Description

Adjustable positioning device

technical field

The invention relates to an adjustable positioning device, in particular to a positioning device which utilizes the elimination of screw spacing to generate friction to achieve the effect of adjusting or adjusting the positioning.

Background technique

At present, the mechanisms used for positioning and tampering can be roughly divided into the following categories:

1. Process the ring groove on the head of the screw. After the screw is tightened, continue to turn the head to break the head from the ring groove, leaving only the threaded part to be locked in the object. If the head is broken with a large force, the internal thread part of the object must have a considerable strength to resist the torsion force, which is easy to cause the problem of thread collapse during use, and the locking degree cannot be adjusted according to the requirements of the object.

2. Design a groove with a special shape on the screw head to match the tool of this shape for locking. In this way, the screw is easier to disassemble, and the construction personnel need to use special tools, which leads to inconvenience in use.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to utilize the adjusting structure to enable the positioning element on the connecting piece to be convenient for the user to adjust the position of the positioning element on the connecting piece, and to produce the effect of positioning or positioning tamper-proof at the proper position.

In order to achieve the above purpose, the present invention includes a connecting piece, a positioning assembly and an adjusting structure, the connecting piece is provided with an external thread portion and a head connected to the side of the external thread portion; A positioning member and an adjustment member, the positioning member is close to the head of the connecting member, and the adjustment member is located on the other side of the positioning member away from the head; the adjustment structure has two convex parts and at least one abutting surface, and the two convex parts are respectively arranged On the two opposite surfaces of the positioning piece and the adjusting piece of the positioning assembly, the abutting surface is formed by the bottom end of one of the convex parts rotating and rising in the direction of the other convex part; the two convex parts are abutted against each other, so that the adjusting piece When the connecting piece rotates close to the head, push the positioning piece to rotate close to the head at the same time, and when the adjusting piece rotates away from the head, the convex part not connected to the abutting surface will gradually approach and abut against the abutting surface, thereby eliminating the positioning piece And the screw spacing between the adjusting part and the external thread part, to produce the positioning effect.

Compared with the prior art, the present invention has the beneficial effects of having both positioning and anti-dismantling effects.

Detailed ways

Please refer to FIG. 1 to FIG. 5. It can be clearly seen from the figures that the adjustable positioning device of the present invention is provided with a connecting piece 1, a positioning assembly 2 and an adjustment structure 3, wherein:

The connector 1 is provided with an external thread portion 11 and a head portion 12 connected to the side of the external thread portion 11;

The positioning assembly 2 is provided with a positioning member 21 and an adjusting member 22. The positioning member 21 has a positioning internal thread 211, and the adjusting member 22 has an adjusting internal thread 221. The positioning member 21 and the adjusting member 22 are connected by the positioning internal thread 211 and the adjusting internal thread. The 221 is screwed to the external thread portion 11 of the connector 1 , the positioning member 21 is close to the head 12 of the connector 1 , and the adjusting member 22 is located on the other side of the positioning member 21 away from the head 12 .

The adjusting structure 3 has a first protruding portion 31 , a second protruding portion 32 and at least one abutting surface 33 . The first protruding portion 31 and the second protruding portion 32 are respectively disposed on the positioning member 21 and the adjusting member 22 of the positioning assembly 2 . For the two opposite surfaces, in this embodiment, the abutting surface 33 is formed by the bottom end of the first convex portion 31 being rotated and inclined upward toward the direction of the other second convex portion 32 .

By virtue of the above, when the present invention is in use, the positioning member 21 of the positioning component 2 is firstly screwed with the positioning inner thread 211 to the outer thread portion 11 of the connecting member 1, and the adjusting member 22 is adjusted with its inner thread 221. It is screwed to the external thread portion 11 of the connecting member 1 so that the first convex portion 31 and the second convex portion 32 are in an opposite shape. Continue to rotate the adjusting member 22 to allow the second convex portion 32 to push the first convex portion 31, so that the positioning member 21 is rotated and locked in with the adjusting member 22 toward the head 12. When the adjusting member 22 is rotated to the proper position, as shown in FIG. 32 will gradually approach and abut against the abutting surface 33, thereby eliminating the positioning internal thread 211 of the positioning member 21 and the screw spacing between the adjusting internal thread 221 and the external thread portion 11 of the adjusting member 22, resulting in a positioning effect; For this positioning effect, the positioning member 21 only needs to be unscrewed toward the side away from the head 12 , and the first convex portion 31 can push the second convex portion 32 to drive the adjusting member 22 to rotate.

Please refer to FIG. 5 and FIG. 6 , it can be clearly seen from the figures that when the present invention needs to produce the anti-removal effect, the positioning member 21 of the positioning assembly 2 is located in the through hole 41 of the object 4, that is, the positioning cannot be rotated by rotation. The positioning member 21 is released from the positioning state of the positioning member 21 and the adjusting member 22, so that the effect of positioning and dismantling can be achieved.
