JP-A-10-220435 Japanese Patent Laid-Open No. 10-246038

  The attachment structure of the end cap to the tubular body described in Patent Documents 1 and 2 is simple because the cap body is pushed into the opening of the pipe by first pushing the opening into the opening of the pipe. The structure is a little complicated.

  On the other hand, the cylinder lock for fitting the key guide as the cap body to the outer cylinder via the retainer is simple in structure, but it must be inserted into the upper ring groove that is elastically deformed. Work is cumbersome and time consuming.

  Accordingly, an object of the present invention is to provide a jig capable of facilitating the mounting operation and simplifying the structure of the mounting portion, thereby eliminating the above-described disadvantages.

  In order to achieve the above object, the invention described in claim 1 is a shallow cup-shaped cap body in which an inner ring groove is formed on the inner peripheral surface of the opening end, and a rod-like or pipe-like shape on which the cap body is fitted. In the state in which the fitting body in which the outer ring groove is formed on the outer peripheral surface of the one end that fits with the cap body is aligned with the inner and outer ring grooves in the axial direction of the fitting body. A ring-shaped retainer is coupled to each other by commonly engaging the inner and outer ring grooves, and holds a fitting body and forms a holding hole for determining an axial position thereof. A first slider guided by a pair of plate-like bodies arranged symmetrically with respect to the holding hole on the surface of the base body so as to be movable in a direction perpendicular to the axis of the fitting body; Superposed on each first slider A second slider which is a plate-like body guided so as to be movable independently of each other, and the first and second sliders are separated from the fitting body in a direction adjacent to the fitting body held by the base body. A first driving end that is a part of an arc having an inner diameter that is substantially the same as the outer diameter of the fitting body, on the mutually opposing end edges of the first slider. The second slider is formed with a second working end edge that is part of a circular arc having substantially the same inner diameter as the first working end edge and is thinner than the plate thickness of the second slider at the mutually facing edges of the second slider, First, a pair of first sliders are brought close to the object to be inserted inserted into the holding hole to form a shelf on which the retainer is placed, and then the second slider is attached. In the direction of reducing the diameter of the retainer by its second working edge close to the body Is sex deformed, while pressing the cap body onto the fitting adherend in this state, characterized in that the first and second slider so as to apart from the fitting adherend.

  The jig according to the present invention configured as described above sets the retainer on the base body, and mounts the retainer around the fit object by sandwiching the fit object between the pair of first sliders. Forming a shelf portion to be placed, and the retainer placed on the shelf portion is pushed and shrunk by the second slider to facilitate engagement of the cap body into the outer ring groove and the inner ring groove. Since the cap body is put on the retainer in the compressed state and the cap body is pressed against the fitting body, the second and first sliders are separated from the fitting body, so that the cap body is attached to the fitting body. It is possible to easily achieve the desired effect.

  In addition, there are various effects such as simplification of the structure of the mounting portion between the cap body and the fitting body.

  In a state where the adherend is fixed to the base body, a ring-shaped retainer is fitted into the outer ring groove of the adherend and temporarily fixed by the action of the first and slider, and in this state, the cap body is covered. The first and second sliders were separated from the fitting body while being pressed against the fitting body, so that the cap body was easily attached to the fitting body.

An embodiment of the invention described in claim 1 will be described below with reference to the drawings.
In this embodiment, the body to be fitted is a main body portion of the cylinder lock, and the cap body is a key guide.

  1 and 2, reference numeral 5 denotes a base body. In the illustrated embodiment, the base body 5 is a block body whose upper surface is long to the left and right, and an elongated bank portion 6 on both sides of the upper surface (upper and lower portions in FIG. 1). , 6 are formed.

  Between the bank portions 6, 6, first and second sliders 7, 8 described later are supported and guided so as to be movable left and right in the drawing.

  Further, a holding hole 9 (see FIG. 2) is formed in the center of the base body 5 so as to penetrate the base body 5 in the vertical direction. In the holding hole 9, a main body portion 11 of the cylinder lock, that is, A cylinder lock with the key guide (cap body) 1 removed is stored.

  Step portions 12 and 12 (see FIG. 8) are formed in the holding hole 9, and an unnumbered step portion of the main body portion of the cylinder lock is engaged with the step portion, and the outer ring groove 4 serves as a base body. Are set so as to be in a predetermined position from the upper surface of 5.

  On the other hand, on the upper surface of the base body, a pair of plate-like first sliders 7, 7 are symmetrical with respect to the holding hole 9, and second sliders 8, 8 are above the first sliders 7, respectively. The first and second sliders 7 and 8 are supported and guided so that they can move in the left-right direction and can move relative to each other.

  In the embodiment shown in the figure, a step portion that is not numbered is formed by stealing the meat on the lower surface of the end portion closer to the holding hole 9 of the pair of second sliders 8, and the first slider 7 is stored in this step portion. Has been.

  As shown in FIGS. 1 and 2, a guide hole 13 that is long in the left-right direction is opened at the end of each second slider 8 that is closer to the holding hole 9, and each guide slider has a corresponding first slider. 7 are engaged so as to be slidable in the left-right direction (see FIG. 8).

  As shown in FIG. 2, a slide spring 15 as a compression coil spring is elastically mounted on an unnumbered step on the lower surface side of each second slider 8.

  The first sliders 7 are biased toward the holding holes 9 by the elasticity of the slide springs 15, but no external force acts on the slide springs 15 due to the engagement between the guide holes 13 and the guide pins 14. In the state, the standby position shown in the figure is maintained.

  On the other hand, as shown in FIG. 1, a pair of first sliders 7, 7 are opposed to each other with a part of an arc having an inner diameter substantially the same as the outer diameter of the cylinder lock body as a fitting body. A first working edge 16 is formed.

  Similarly, a second working end edge 17 having substantially the same inner diameter as the first working end edge 16 is also formed at the end edges of the pair of second sliders 8, 8 facing each other.

  However, as shown in FIG. 8, the upper surface side of each second working end edge 17 is scraped along an arc, and the end portion of each second working end edge closer to the holding hole 9 is thin.

  On the other hand, as shown in FIG. 1, a drive mechanism 18 as a link mechanism is provided on the upper surface side of the base body 5.

  The drive mechanism 18 includes first and second drive levers 19 and 21, and each drive lever is rotatably supported on a support shaft 22 fixed to a base frame (not shown) on the upper surface side of the base body 5. The support shaft 22 can be freely rotated in a plane parallel to the upper surface of the base body 5.

  The upper ends of the first and second drive levers 19 and 21 are linked to each other via a connecting lever 23, and the first drive lever 19 is shown through the engagement of a connecting hole 24 and a connecting pin 25. 1, the second drive lever 21 is connected to the second slider 8 on the right side in FIG. 1 through the engagement of the connection hole 24 and the connection pin 25, respectively.

  The second drive lever 21 is interlocked with the first drive lever by holding the grip ball 26 provided at the free end of the first drive lever 19 and turning the first drive lever 19 counterclockwise. And can be rotated counterclockwise.

  In the first and second drive levers 19 and 21, the engaging portions of the connecting hole 24 and the connecting pin 25 are provided symmetrically with respect to the support shaft 22, so that the first and second drive levers rotate. The pair of second sliders 8 and 8 are driven in a direction approaching the holding hole 9.

  As shown in FIGS. 1 and 2, the jig according to one embodiment of the present invention configured as described above inserts a cylinder lock body 11 into a holding hole 9 of a base body 5. The lock body 11 is metastablely fixed in the holding hole 9.

  Next, when the gripping ball 26 of the drive mechanism is held and moved to the right, the pair of second sliders 8 and 8 are pushed by the first drive lever 19 or the second drive lever 21 via the connecting pins 25, respectively. The second working end edges 17 and 17 move in a direction to sandwich the cylinder lock body.

  However, as described above, the first slider 7 is housed in the lower surface step portion of the second slider 8, and the slide spring 15 is elastically mounted between the first slider 7 and the lower surface step portion of the second slider. Since the elasticity of the slide spring 15 is larger than the frictional resistance of the first slider 7, the first and second sliders 7 and 8 slide integrally.

  Also, as shown in FIG. 1, the first slider 7 is closer to the holding hole 9 than the second slider 8 out of the overlapping first and second sliders 7, 8, so the first slider 7 is the second one. Moves ahead of the slider 8.

  As a result, as shown in FIGS. 3 and 4, the first operating end edge of the first slider 7 is joined to the portion immediately below the outer ring groove 4 of the adherend (cylinder lock) 11. .

  Then, an unnumbered shelf portion is formed on which the retainer 27 (see FIG. 5), which is made of an elastic material and has a substantially C-shape as a whole, is placed. As shown in FIG. Is placed.

  When the gripping ball 26 of the drive mechanism 18 is further moved to the right from this state, as shown in FIGS. 6 and 7, the second slider is brought into contact with the first slider 7 stopped by the cylinder lock 11. 8 moves relatively while pushing and shrinking the slide spring 15.

  As a result, as shown in FIGS. 6 to 8 (particularly FIG. 8), the thin second working edge 17 at the tip of the second slider 8 presses and retracts the retainer 27 placed on the shelf, and this is compressed into the outer ring. It can be pushed into the groove 4.

  It should be noted that the dimensions of the first and second operating edges, particularly the thickness, the vertical position and the relative positional relationship are appropriately set so that the operation described above and shown in FIG. 8 is possible.

  Next, the cap body 1 faces the upper end of the cylinder lock 11 with its opening facing downward, and the lower end opening of the cap body 1 is fitted to the upper end of the cylinder lock as shown in FIG.

  At this time, it is preferable to set the thickness of the second working edge 17 so that the inner peripheral surface of the lower end opening of the cap body 1 can be slightly fitted with the retainer 27.

  As shown in FIG. 8, when the lower end opening of the cap body 1 is slightly fitted to the fitting body, the grip ball 26 of the drive mechanism is moved to the left, and the pair of second operating edges 17 and 17 are moved. While expanding, the cap body 1 is pushed downward, and the lower end edge of the cap body 1 is dropped into a first working end edge shape.

  Further, the grip ball 26 of the drive mechanism is further moved to the left, the pair of first operating end edges 16 and 16 are expanded, the cap body 1 is further pushed downward, and the lower end edge of the cap body 1 is a cylinder. It is joined to a step formed on the outer surface of the lock.

  Then, the retainer 27 that has elastically contacted the inner peripheral surface of the opening end portion of the cap body 1 is aligned with the inner ring groove 3 of the cap body, and at this time, the retainer returns to its original shape due to its elasticity. And since it straddles inner ring grooves 3 and 4, a cap body and a to-be-fitted body are combined stably and reversibly.
