Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a socket removal device for a box socket, and more particularly to a socket removal device of the type in which a cylindrical body for socket removal is provided around the outer circumference of a plug.

As this kind of socket removal device,
The one described in Publication No. 43591 is known. In this device, a cylindrical body 1 serving as a socket removal device is provided on the outer periphery of a plug 2 so as to be movable up and down. Connecting the socket 3 by associating the concave groove 7 with the protrusion 8 of the cylinder 1
There is an interlock mechanism (safety device) for removal. (Fig. 1, Fig. 2) The above-mentioned conventional box pot is used by burying the box 5 that accommodates the pot body 4 in the wall or floor, but the buried depth is not constant and in some cases , as shown in the same figure, may be buried deep in the wall or floor.

In this case, the socket 3 can be easily connected to the plug 2 by simply pushing it in, but since the cylinder 1 is located deep, it is difficult to pull up the cylinder when removing the socket. Difficult to do.

The present invention is based on the following features: A socket attached to the plug 2 can be removed by pulling up the cylindrical body 1 that surrounds the outer periphery of the plug of the main body buried deep inside the opening formed in the wall surface, etc. To provide a socket that can be easily removed without being affected by the depth at which the socket is buried in the socket.

The technical means of the present invention for solving the above problems is as follows: In addition to fitting the secondary cylinder 9 into the cylinder body 1, the two cylinders 1 and 9 are connected to each other by using screws carved on the interface between them. or these two cylinders 1,
9 are connected via a one-way clutch means that acts to prevent movement of the sub-tube 9 in the drawing direction, so that the tip of the sub-tube 9 is connected to a wall surface formed as an entrance to the box stock side. It is possible to move from the vicinity of the opening to the depths thereof.

The above technical means works as follows.

When burying the box socket deeply in a wall or floor surface, it is sufficient to fix the sub cylinder 9 in a state in which it is pulled out from the cylinder body 1 in advance. The tip of the sub-tube 9 pulled out from the box will be located near an opening formed in the wall or the like (an opening that will be the entrance to the box).

Next, when the tip of the sub-tube 9 located near the opening is pulled up, the sub-tube 9 is threadedly connected to the cylinder body 1, or the sub-tube 9 is pulled out of the drawer. Since the cylinder body 1 is connected via a one-way clutch means that acts to prevent movement in the direction, the cylinder body 1 moves together with the sub-cylinder 9 that has been pulled up.
The cylindrical body 1 allows the socket attached to the plug 2 to be removed.

Next, a case will be described in which the box stick is buried shallowly in a wall or floor.

First, when adopting a configuration in which the cylinder body 1 and the sub-cylinder 9 are screwed together, the screwing amount of both of them is adjusted.
In addition, when adopting a configuration in which the sub cylinder 9 and the cylinder body 1 are connected via a one-way clutch means, the sub cylinder 9
The amount of protrusion of the sub cylinder 9 is adjusted by pushing it in the direction of the cylindrical body 1 by the required amount.

As a result, the amount by which the sub-tube 9 protrudes from the cylindrical body 1 becomes shorter, and if the box stock with the protruding amount of the sub-tube 9 shortened is buried shallowly in a wall or floor surface, the tip of the sub-tube 9 can be moved from the wall surface. It will be located near the opening formed in the area.

The present invention has the following unique effects.

Even if the buried depth of the box stock changes, by adjusting the amount of protrusion of the sub cylinder 9 relative to the cylinder 1, the tip of the sub cylinder 9 can be formed near the opening for installing the box stock on the wall surface, etc. Since the cylindrical body 1 at the back thereof can be pulled up through the sub-cylindrical part 9, the socket can be easily removed.

Even if the socket socket is buried deep or shallow depending on the installation conditions, the degree of engagement between the secondary cylinder and the cylinder body can be adjusted, so the upper end of the secondary cylinder, which serves as the knob for removing the socket, is always on the floor. Or it will be located at an appropriate position near the wall surface. Therefore, even when the installation depth is shallow, there is no need to worry about the sub-tube becoming jammed.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the first embodiment shown in FIG. 3, a sub cylinder 9 is fitted inside the cylinder body 1, and the inner diameter of the sub cylinder is set to a diameter that can accommodate the socket, and the inner surface of the cylinder body 1 and the secondary cylinder are set to a diameter that can accommodate the socket. A one-way clutch means is provided between the outer surfaces of the tube 9. This one-way latch means includes a large number of engagement steps 10 with a sawtooth cross section provided on the sub-tube 9, a pair of engagement protrusions 11 provided on the cylindrical body 1,
11 to prevent the sub-tube from being pulled out independently after adjusting the degree of insertion of the sub-tube.
The inclined part 12 of the engagement step part 10 is set to face downward, and the horizontal part 13 is set to face upward, while the engaging projections 11, 11 of the cylindrical body 1 are set so that the horizontal part 14 faces downward. be. (Fig. 4) In addition, a slit 15 is cut in the body of the sub-tube 9 in the axial direction so as to open at the lower end, so that the degree of insertion can be easily adjusted, that is, the degree of insertion can be adjusted with a light force. It's like this.

Incidentally, in order to enable the above-mentioned insertion, the sub-tube 9 is formed of an elastic material such as synthetic resin.

Next, in the second embodiment shown in FIG.
A male thread 16 is installed on the outer periphery of the cylindrical body 1, and a female thread 1 is installed on the inner periphery of the cylindrical body 1.
7 are formed and screwed into each other, and the inner diameter of the sub-tube 9 is made larger than the diameter of the socket.

In this case, it is necessary to hold the cylindrical body 1 on a fixed part in a rotation-preventing manner, and as in the conventional example shown in FIG. 1, the cylindrical body is mated against the fixed part.

In this second embodiment, by adjusting the screwing depth of the sub-tube 9, the fixing position of the sub-tube 9 can be set that is optimal for the mounting conditions of the box stock.

In each of the above embodiments, the sub cylinder 9 is fitted inside the cylinder 1, but the sub cylinder 9 may be fitted externally.In this case, the inner diameter of the cylinder 1 is set to accommodate the socket. The diameter should be set to an acceptable diameter.

It goes without saying that the socket removal device of the present invention can be used for all box sockets (buried gas sockets) in which the socket is removed by pulling up a cylindrical body provided on the outer periphery of the plug.
