It is another object of the present invention to provide a device that can be performed without human intervention. [0005] In order to achieve the above object, a first sliding hole having a first sliding hole penetrating from one end to the other end is provided.
An outer diameter D1 having a second sliding hole penetrating from one end side to the other end side, and being slidable fluid-tight on one end side along the sliding hole of the first cylindrical member. A second cylinder having a flange-shaped large-diameter piston portion and an extrusion-extending cylindrical portion extending from the large-diameter piston portion toward the other end and having an outer diameter smaller than the first sliding hole. Member; inner diameter D3 penetrating from one end to the other end
And has an outer diameter D2 smaller than the outer diameter of the large-diameter piston on one end side, and one end side is substantially directed toward the end face on the one end side of the large-diameter piston. A flange-shaped small-diameter piston portion formed so as to be able to abut fluid-tightly, and a first fluid-tightly slidable with respect to the second sliding hole extending from the small-diameter piston portion toward the other end. A third cylindrical member having a release extended cylindrical portion having a sliding outer peripheral surface; a first cylindrical member fixed to one end surface of the first cylindrical member and closing one end of the first sliding hole. A flange; and an insertion hole fixed to the other end surface of the first cylinder member, and having an insertion hole through which the extrusion cylinder portion of the second cylinder member is fluid-tightly inserted, and an outer peripheral surface of the release extension cylinder portion. A second flange having an insertion hole that can be inserted in a fluid-tight manner and closing the other end of the first sliding hole; having a center hole and having one end to the other end A male connector portion extending at one end, substantially fixed to the first flange by inserting the first flange in the axial direction, and having a male connector portion having an annular protrusion at the other end; A fourth cylindrical member having a sliding outer peripheral surface that slides along the third sliding hole of the third cylindrical member at an intermediate portion between the first flange and the second flange.

A female connector with a female connector is detached from the male connector, and a hose with a female connector is configured as a test attaching / detaching device. Since the present invention is constructed as described above, the second
When the fluid is supplied to the second through-hole communicating with the first sliding hole by facing the other end of the large-diameter piston of the second cylindrical member from the outside with the flange of the second cylindrical member, Fluid pressure acts on the other end of the large-diameter piston portion, and moves the third tubular member together with the second tubular member and the second tubular member from the other end of the first tubular member to one end. be able to. At this time, since the third tubular member is separated from the annular projection of the male connector portion on the other end side of the fourth tubular member, the female connector fixed to one end of the hose should be connected to this male connector portion. Can be. On the other hand, when fluid is supplied to the first through-hole communicating with the first sliding hole while the first flange faces the one end side of the large-diameter piston of the second cylindrical member from the outside, the third flange is formed. Since the outer diameter D2 of the small-diameter piston portion of the cylindrical member satisfies the following expression, the following expression is obtained.
In a state where the small-diameter piston is substantially in fluid-tight contact from one end side to the other end side, the third cylindrical member is joined to the fourth cylindrical member from one end to the other end together with the second cylindrical member. It can be moved by a fixed amount. That is, the distal end of the extension cylindrical portion for release of the third cylindrical member is forcibly displaced radially outward from the deformable claw of the holding member of the female connector connected to the connection position of the male connector portion of the fourth cylindrical member. The third tubular member can be moved to a position where the third tubular member can be spread, and the claw of the holding member can be kept in a spread state. Thereafter, when the third tubular member stops, the second tubular member moves from one end side to the other end side with respect to the second tubular member, and the second tubular member moves to the second tubular member.
The pushing of the rear end of the holding member expanded by the push-out extension cylindrical portion of the cylindrical member allows the female connector to be detached from the male connector portion. Therefore, the fluid can be supplied to the hose through the central hole of the fourth cylindrical member, and after performing an airtightness test or the like of the hose with the female connector, the hose can be easily removed from the male connector portion for testing using the apparatus. Can be removed. An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numeral 10 denotes a first cylindrical member,
The first sliding hole 10a penetrating in the axial direction penetrates from one end 11 to the other end 12, and is used by being fixed to a base (not shown). The first sliding hole 10a has one end 11 in the axial direction.
A second cylindrical member 20 having a second sliding hole 20a penetrating from the side to the other end 12 is disposed so as to be movable along the first sliding hole 10a. Specifically, the second cylindrical member 20
Has an outer diameter D on one end side in a fluid-tight manner with respect to the first sliding hole 10.
A large-diameter piston portion 21 having a flange shape, and an extended cylindrical portion 22 for extrusion having an outer diameter smaller than the outer diameter of the large-diameter piston portion 21 is integrally formed from the large-diameter piston portion 21 toward the other end. The extension cylindrical portion 22 for extrusion is provided at the center of a second flange 60 fixed to the other end 12 of the first cylindrical member 10 by using four bolts 61. It is inserted through the hole 60a, supported in a fluid-tight and slidable manner,
As a result, the large-diameter piston portion 21 is movably supported along the first sliding hole 10a. A third cylindrical member 30 having a third sliding hole 30a penetrating from one end to the other end is held movably along the sliding hole 20a of the second cylindrical member 20. I have. Specifically, the third cylindrical member 30 has a flange-shaped small-diameter piston portion 31 having an outer diameter D2 smaller than the outer diameter of the large-diameter piston portion 21 at one end, and a third end at the other end. And a release extension cylindrical portion 32 extending from the piston portion 31 toward the other end side. The release extension cylindrical portion 32 can slide in the second slide hole 20a in a fluid-tight manner. One sliding outer peripheral surface 33 is formed. A fitting hole formed at one end of the large-diameter piston portion 21 is provided so as to be fitted to the other end of the small-diameter piston portion 31, and formed at the other end of the small-diameter piston portion 31. An annular contact surface 31a is brought into contact with the large-diameter piston portion 21 such that it can be separated from the end surface 21a on one end side. More specifically, the working area S2 at one end of the small-diameter piston portion 31 is larger than the annular working area S1 at one end of the large-diameter piston portion 21. A first flange 50 for closing the first sliding hole 10a is fixed to one end 11 surface of the first cylindrical member 10 by four bolts 52, and a shaft hole 40 extending in the axial direction is provided.

And fixed with a nut 53 via a seat plate 51, and an intermediate portion 4 between the one end 41 and the other end 42.
The third cylindrical member 30 described above is movably fitted into the first sliding hole 10a. Therefore, a second sliding outer peripheral surface 43a which fits into the third sliding hole 30a is formed in the intermediate portion 43 so that the third cylindrical member can move smoothly. The other end 42 of the fourth tubular member 40 has an annular protrusion 42a formed at a position separated by a certain distance from the other end, and is formed on the male connector portion 42. It functions as a piping member. As shown in FIG. 1, when the third tubular member 30 is moved to one end together with the second tubular member 20, a female connector drawn by a two-point flange line is attached to the male connector. The hose 80 having 70 can be connected with one touch. That is, the female connector 70 includes a cylindrical housing 71 and a holding element 72 having an arm claw 72a that can be biased outward in the radial direction.
It is fitted and held at one end of one shaft hole. Therefore, when the female connector 70 is inserted toward the one end side relative to the male connector, the arm claws 72
When the arm claw 72a is further forcibly inserted, the arm claw 72a is deformed radially outward into a bias, so that the arm claw 72a can pass through the annular protrusion 42a and the arm claw 72a is restored. The female member 70 can be connected to the male connector portion 42 with one touch by locking behind the annular projection 42a. In the connector connection thus connected, as described above, the working area S2 on one end of the small-diameter piston portion 31 is made larger than the annular working area on one end of the large-diameter piston portion 21. That is, assuming that the outer diameter of the fourth cylindrical member is D3, the following expression is satisfied. Therefore, the third cylindrical member 30 is moved together with the second cylindrical member 20 from one end side. It can be moved to the other end, and first, after the end 32a of the extension cylindrical portion 32 for release formed on the other end of the third cylindrical member 30 contacts the surface of the arm claw 72a of the holding element 72, the arm claw 72a Can be pushed outward in the radial direction, the movement is prevented by the annular projection 42a, and the connection between the male connector 42 and the female connector is releasably connected. Therefore, with the arm pawl 72a pushed outward in the radial direction, the large-diameter piston portion 2
By moving the push-out tube portion 22 of the second tube member 20 toward the other end so as to be away from the small-diameter piston portion 31 by 1,
After the end 22a of the pushing cylindrical portion 22 of the second cylindrical member 20 abuts on the rear end 72b of the arm pawl 72 of the holding element 72, the female connector 70 is connected to the male connector 42 together with the housing 71. The female connector 70 can be moved toward the end side, and the female connector 70 can be easily removed from the male connector portion 42 using the above-described device. The details of the female connector 70 adopted here are described in detail with reference to FIGS. 15 to 17 in Japanese Patent Publication No. 6-31668, but are not limited to this female connector. is not. For example, Japanese Utility Model 4-13

For example, the connector disclosed in Japanese Patent No. 419 can be used for a connector of a type in which the engaging claw is released by moving the extension cylindrical portion 32 for release in the axial direction so that the male connector portion 42 and the female connector can be detached. . On the other hand, the female connector 70 is
As shown in FIG. 1, it is necessary to move the large-diameter piston portion 21 to one end side. In order to move the large-diameter piston portion 21 from the other end portion to the one end side in the first sliding hole 10a in this manner, the second flange 60 has a second through hole communicating with the first sliding hole 10a. 62, an external pipe (not shown) connected to the second through hole 62a is connected, and a fluid is supplied to the other end 21b of the large-diameter piston portion 21 by the pressure fluid supplied through the pipe. Is supplied, and the third cylindrical member 30 is also moved from the other end to the one end with the second cylindrical member 20. At this time, since the first flange 50 is also provided with the first through hole 53 communicating with the outside and the first sliding hole 10a, the first flange 21 on the one end 21a of the large diameter piston portion 21 is formed. The fluid in the sliding hole 10a is discharged to the outside through an external pipe connected to the screw hole 53a formed in the first through hole 53. As described above, by moving the second tubular member 20 and the third tubular member 30 from the other end to one end,
As shown in FIG. 1, the female connector 70 can be connected.
As described above, in order to release the connector connection thus connected and remove the hose 80 with connector,
The third cylindrical member 30 is moved together with the second cylindrical member 20 from one end to the other end, and then the second cylindrical member 20 is moved.
