Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nut locking seat fixture.

The applicant previously proposed a locking seat for a nut screwed onto a bolt.

First of all, the specific structure of this nut locking seat will be explained with reference to Figs. 1 to 3. The nut locking seat R is manufactured according to a standard or method that matches the pitch and height of the bolt. Therefore, it is necessary to set the thickness and width to increase the snapping force according to the load conditions, purpose of use, etc.

As shown in the first diagram, the planar shape of the gap 1 is
It is approximately ring-shaped with a notch at 0, and a set circumferential pressure 1L12 is formed around this gap, and long grooves 13 and 14 are bored in this seat along the rotational direction of the nano 1-N. be.

The locking seat R is the screw thread Ba of the bolt B (Fig. 3).
It has a twisted fitting part so that it can be fitted with a one-pitch shift.

By the way, as shown in the first and third figures, first rotate the nut N to screw it into the thread of the bolt B, and then tighten the locking seat R.
into thread Ba of bolt B.

By the way, even if the nut rotates in the return direction after tightening the Nano l-N in a predetermined position and starts to loosen,
Since the locking seat R engages with the screw thread Ba of the pole I-B, it is impossible to rotate this nut any further in the return direction.

By the way, one way to install the locking device R with the above structure by screwing it onto the bolt B is to insert the tip of a screwdriver or the like into the long groove 13 and rotate the locking seat. This method has poor work efficiency, and the screwdriver often damages nuts and other nearby equipment.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a mounting tool that can easily fit and rotate the nut H locking tool R of the above-mentioned structure onto the bolt B to attach or remove it.

An embodiment of the present invention will be explained based on FIGS. 4 to 8. In FIG. 4, the body A of the fixture has a bolt B in the center.
It has a hollow part 1 through which it passes, and there are protrusions 2,
3 is a protrusion.

These protrusions 2 and 3 are connected to the long grooves 13 and 14 of the locking seat R.
It is sufficient that at least one protrusion is provided, but the installation and removal work is further improved by providing two protrusions.

When one protrusion (the left protrusion 2 in Fig. 4) is connected to the outer end 13a of the long groove 13 (Fig. 1), the gap between these two protrusions 2 and 3 is the gap between the two protrusions 2 and 3. It is necessary that the protrusion 3 (on the right side in FIG. 4) does not join to the inner end 14a of the other long groove 14 (FIG. 1).

Therefore, the operation of attaching the locking seat R to the pole I-B using the fixture A according to the present invention will be explained.

First, the two long grooves 13 and 14 of the locking seat H are engaged with the protrusions 2 and 3 of the fixture A, respectively.

In this case, if you embed a permanent magnet on the side of fixture A,
The locking seat R can be easily and stably attached to the fixture A by the attraction force between the two protrusions 2 and 3 and the magnet.

In Figs. 6 to 8, when the fixture A is rotated in one direction (counterclockwise in Fig. 8), one protrusion 2 pushes the outer end 13a of the long groove 13, and this locking seat R is rotated into the position B. Screw together.

At this time, the other protrusion 3 is not in contact with the inner end 14a of the other long groove 14, so this locking seat R is in the gap 10 (first
Figure) and S are expanded, so that the locking seat can be smoothly screwed onto the bolt B and tightened until it is joined to the side surface of the N nut N.

When the tightening work is completed, the fixture A can be pulled out from the bolt B.

In addition, when removing the locking seat R, it is sufficient to perform the reverse operation as described above, and in this case as well, pass the hollow part 1 of the fixture A through the port L-B, and insert it in the loosening direction (clockwise in Fig. ), the protrusion 3 now joins the outer end 14b of the elongated groove 14 (FIG. 1), while the other protrusion 2 joins the inner end 1 of the elongated groove 13.
3b (Fig. 1), the locking seat R opens and expands due to the gap 10, and as a result, the tight contact between the locking seat R and the pole I-B is released, and the locking seat R is rotated five times. By doing so, the locking seat, nut N, and bolt B can be removed smoothly.

Note that the outer peripheral shape of the fixture A is desirably shaped so that it can be easily held, and it is also appropriately selected to have a shape that allows it to be attached to a machine or the like.

Since the present invention has the above configuration, a set circumferential pressure is formed around the gap, a long groove is bored in the set circumferential pressure, and a nut locking seat that can be fitted to the thread of the bolt by shifting it by one pitch is formed. Installation and removal work can be done easily, quickly, and accurately.
