Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ratchet trench for a temporary frame in which a replacement socket can be conveniently stored in a handle.

[Conventional technology]

The ratchet trench for temporary frames that tightens and loosens the nuts of round separators used at concrete wall formation sites that use temporary frames can be used for two types of round separators that use 21 hex nuts and 12 hex nuts. If it's not practical, it's not practical.

Therefore, only one replacement socket that can be used for small hexagonal nuts is always kept, and this replacement socket is removably inserted into and attached to a rotating socket that is applied to large hexagonal nuts for different uses.

In this way, I use the replacement socket by attaching or removing it as needed, but when I am not using it, I usually put it in the pocket of my work clothes or work pants, so it gets in the way and interferes with my work. You may forget to bring it with you to the temporary frame site, or you may lose it immediately, or you may accidentally damage it during work. There were drawbacks such as the possibility of dropping the product.

[Problem that the invention attempts to solve]

The technical problem of the present invention is to solve the above-mentioned drawbacks using the following concept.

First, both the handle 1 and the replacement socket 4 are made of pipe.

In this way, since both are made of pipe, by expanding the base end side of the handle 1, the replacement socket 4 having a small diameter portion and a large diameter portion can be easily inserted therein.

At this time, a spring plate 7 is attached to the side surface of the replacement socket 4 to exert an elastic locking action to prevent detachment.

Moreover, the attachment of the spring plate 7 is designed to exert a similar elastic locking effect even when the replacement socket 4 is fitted into the rotating socket 3, thereby preventing it from coming off.

[Means for solving problems]

The gist of the present invention will be explained with reference to the accompanying drawings.

A working main body 2 is connected to the tip of the handle 1 so that it can be bent at right angles, and a rotating socket 3 that rotates by a ratchet rotation mechanism is provided on the working main body 2. In a ratchet trench for a temporary frame that can be applied to two types of hexagonal nuts for round separators by removably fitting a replacement socket 4 that is applied to a hexagonal nut smaller than the hexagonal nut to which the socket 3 is applied, the handle 1 The large-diameter portion 4b of the replacement socket 4 is inserted into the proximal end member of the handle 1 made of this pipe through the tapered portion 1'. A large-diameter socket storage portion 5 is formed that bulges to an inner diameter that can be inserted, the replacement socket 4 is formed from a pipe, and a part of the spring plate 7 is made to protrude from the circumferential surface of the replacement socket 4 made of the pipe. This relates to a ratchet trench for a temporary frame, characterized in that a replacement socket 4 having an elastic locking portion 7a is removably fitted into a socket storage portion 5.

[Effect]

When using the replacement socket 4, insert your finger into the replacement socket 4 and press the inner surface of the replacement socket 4 while pulling it out, and the elastic locking part 7a of the replacement socket 4 will be pressed and removed. The replacement socket 4 can be easily pulled out from the socket accommodating portion 5 and fitted into the rotating socket 3 to accommodate a small hexagonal nut.

On the other hand, after use, simply push the replacement socket 4 into the socket storage part 5 of the handle 1, and the elastic locking part 7a will close.
The elastic locking action prevents the device from falling off.

〔Example〕

The working main rod 2 is shown in a case where it can be used by being bent at 90 degrees with respect to the handle 1.

Further, a spanner portion 6 is formed at the tip of the main working rod 2.

The replacement socket 4 is constructed by protruding a spring protrusion 7a of a spring plate 7 from the outer periphery of the insertion portion 4a, and pressing the spring protrusion 7a against the inner peripheral surface of the fitting hole 8 of the rotation socket 3. The figure shows a case in which the holder is fitted into the rotating socket 3 in a manner that prevents it from coming off.

In addition, the socket storage portion 5 has an annular locking groove 9 formed on its inner circumferential surface, and the elastic locking portion 7a of the spring plate 7 of the replacement socket 4 is pressed against the ring-shaped locking groove 9 and is removed. Although the figure shows a case in which the spring plate 7 is fitted and fixed in the stopped state, various designs can be made for the locking structure of the spring plate 7.

10 in the figure is a ratchet switching lever.

[Effect of idea]

As mentioned above, when the replacement socket 4 is used, the replacement socket 4 is taken out from the socket storage part 5 and fitted into the rotation socket 3 as shown in FIG. 2, and when the replacement socket 4 is not used, the replacement socket 3 is rotated. Since it is taken out from the moving socket and stored and fixed in the socket storage part 5 as shown in Fig. 1, the replacement socket 4 that is not in use does not get in the way at all, so there is no problem with the work, and that is all. Work efficiency is improved, the pocket is not damaged or lost, and the replacement socket 4 can be quickly taken out from the socket storage section 5 and replaced for use, making it even more convenient. This will improve work efficiency.

The replacement socket 4 is stored and fixed in the handle 1 by the spring protrusion 7a of the spring plate 7, as shown in the drawing.
By having a structure in which the replacement socket 4 is locked to the inner circumferential surface of the socket storage part 5, the replacement socket 4 can be securely stored and fixed in the socket storage part 5, and it is also easy to take out the replacement socket 4. It can be easily taken out by simply pushing a finger into the replacement socket 4 and pulling it out.

Thus, the present invention provides a ratchet trench for a temporary frame that improves work efficiency since the replacement socket 4 is stored in the socket storage part 5 so as not to get in the way when not in use. Structurally, both the handle 1 and the replacement socket 4 are made of pipe, and a socket storage part 5 for storing and fitting the replacement socket 4 is formed at the rear end of the handle 1 through a tapered part 1'. Socket storage section 5
Since the replacement socket 4 is fitted exactly inside the replacement socket 4, the storage structure of the replacement socket 4 is extremely simple, and it is easy to manufacture and suitable for mass production. It is effective.
