Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an extrusion device for extruding viscous substances such as grease or compounds (injected into compression clamps for overhead transmission lines).

For example, in an extrusion device for injecting into a compression clamp, as shown in FIG.
A lid 5 is placed between the opening end 3 of the container 1 and a sealing material 4.
is attached, and a pouring nozzle 7 is formed in the opening 6 of the lid 5, and the pouring nozzle 7 is screwed to a nozzle inlet (not shown) of a compression clamp (not shown). Therefore, when inserting the pouring nozzle 7 of the extrusion device into the nozzle inlet of the compression clamp, the entire extrusion device must be rotated, and this work requires skill if performed at a high place. Not only was it dangerous, but it was also dangerous work.

The present invention has been made to solve these drawbacks, and the first aspect of the invention is a viscous material extrusion device in which an extrusion tool is slidably housed in a container for accommodating a viscous material. This is a viscous material extrusion device in which a partition wall formed of an elastic body is attached to the open end of the container, and a slit is provided in the partition wall.
The structure of the invention is that in a viscous material extrusion device in which an extrusion tool is slidably housed in a container for storing a viscous material, a partition wall formed of an elastic material is attached to the open end of the container, and a partition wall formed of an elastic material is attached to the partition wall. This is a viscous material extrusion device with a thin wall section.

An embodiment of the first invention will be described based on the drawings. As shown in FIGS. 2 and 3, an extrusion tool 12 is slidably housed in a container 11 containing compound a, and a partition wall 13 made of rubber is attached to an open end 11a of the container 11 as a lid. As shown in FIGS. 4 and 5, the partition wall 13 has a ring-shaped clamping part 15 which is clamped by the opening end 11a and the lid 14, and an inner side of the clamping part 15. It consists of a truncated conical partition part 16 that covers the container 11, and a fitting part 1 that extends in the axial direction of the container 11 inside the clamping part 15.
7 is protruded, and its fitting portion 17 is fitted into the inner surface of the open end 11a of the container 11, and in order to enhance the fitting effect of the fitting portion 15, the fitting portion 15 and the fitting portion 17 are A concave portion 18 is formed on the outer periphery of the root portion. The inside of the fitting part 17 is formed into a tapered shape 17a whose tip side widens outward. Further, a cross-shaped slit 19 is cut from the center of the partition portion 16. The lid body 14 is provided with an opening 20 at a position opposite to the slit 19, and projects outward from the opening 20 to the connecting pipe 21.
A pouring nozzle is connected to the outer circumference of the pouring nozzle 22, and a threaded groove 23 is formed on the outer circumference of the tip of the pouring nozzle 22.

Next, the effect will be explained. The compound a is filled into the container 11, the partition wall 13 is inserted into the open end 11a of the container 11, and the lid 14 is attached from the outside of the partition wall 13. On the other hand, only the pouring nozzle 22 is removed from the connecting pipe 21 of the lid 14 and screwed into the injection port 24 of the compression clamp B. Then, by connecting the connecting pipe 21 of the lid body 14 to the injection nozzle 22 and moving the extrusion tool 12, the container 1
Compound A in 1 pushes open the slit 19 of the partition wall 13, passes through the partition 16, the connecting pipe 21 and the pouring nozzle 22, and is filled into the injection port 21 of the compression clamp B. Since the slit 19 closes due to its own elastic force unless the pressure of the compound a is applied, the compound a in the container 11 is
There is no leakage from the partition wall 13.

Further, a fitting part 17 is provided on the outer periphery of the partition wall 13, and the inside of the fitting part 17 has a tapered shape 17a with a tip expanding outward. Therefore, when the pressure from the inside increases due to extrusion of the viscous material a, the outside of the fitting part 17 spreads outward and comes into close contact with the container 11, improving the sealing performance, and the viscous material a is released from this part. There is no risk of it leaking.

As described above, in the first invention, a partition wall formed of an elastic material is attached to the open end of the container, and a slit is provided in the partition wall, so that the pouring nozzle can be removed from the container. If a coupler method is adopted to connect the connecting pipe of the lid and the pouring nozzle as in this embodiment, even if a thread groove is formed in the injection port, the entire extrusion device can be operated without rotating. It can push out viscous substances.

Further, since a fitting portion is provided on the outer periphery of the partition wall to spread outward due to the pressure of the viscous contents and improve the sealing performance with the container, there is no risk of the contents leaking during extrusion.

Next, an embodiment of the second invention will be described based on FIG. 6. This viscous material extrusion device is based on the partition portion 16 of the partition wall 13 in the extrusion device A of the embodiment of the first invention.
The thin wall portion 24 can be easily torn, and by moving the pressing tool 12, the thin wall portion 24 can be easily torn.
ruptures under the pressure of compound a, and compound a
is the pouring nozzle 22 as in the embodiment of the first invention.
being pushed out from Since the thin wall portion 24 is formed of an elastic body, it will close due to its own elastic force unless the pressure of the compound a is applied.
The compound a in the container 11 does not flow out through the partition wall 13. Furthermore, the thin portion 24
A notch-like groove may be formed in advance so that it can be easily torn.

As described above, in this second invention, a partition wall formed of an elastic material is attached to the open end of the container, and a thin wall portion is provided on the partition wall, so that the pouring nozzle can be removed from the container. Therefore, if a coupler method is used to connect the connection part of the lid body and the pouring nozzle as in this example, even if a thread groove is formed in the injection port, the entire extrusion device can be rotated. It can push out viscous substances without any pressure.

Further, if the partition wall is also used as a sealing material between the container and the lid, the number of parts of the entire extrusion device can be reduced.
