DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides an embodiment: an anti-loosening self-adjusting fastener, including a cross frame 4, a positioning device 3 is slidably installed at the front end of the cross frame 4, and a guide device 2 is slidably inserted on both sides of the positioning device 3. An alignment device 1 is rotatably installed inside the guide device 2. The alignment device 1 includes a hexagonal hole 5, an alignment sleeve 6 and a gear 7. The hexagonal hole 5 is opened inside the rear end of the alignment sleeve 6, and the alignment sleeve 6 is fixedly installed at the rear end center of the gear 7. The positioning device 3 includes a positioning bolt 15, a slot 16 and a clamp 17. The positioning bolt 15 is threadedly inserted at the top two ends of the clamp 17, and the slot 16 is opened inside the two sides of the clamp 17.
[0021] The guide device 2 includes a support ring 8, an extension base 9, a sliding rod 10, a reset spring 11, a support cavity 12, a rack 13 and a U-shaped sliding key 14. The support ring 8 is fixedly installed on the side end of the U-shaped sliding key 14, the extension base 9 is fixedly installed on the side end of the support ring 8 away from the U-shaped sliding key 14, the support cavity 12 is fixedly installed on the front end of the extension base 9, the sliding rod 10 is slidably inserted into the interior of the support cavity 12, the rack 13 slides through the support cavity 12 and is connected to the sliding rod 10 at one end close to the U-shaped sliding key 14, and the reset spring 11 is symmetrically fixedly installed between the rack 13 and the support cavity 12. The elasticity of the reset spring 11 can drive the rack 13 to quickly dock with the gear 7.
[0022] The U-shaped sliding key 14 is slidably inserted into the inside of the clamping groove 16, the clamp 17 is slidably installed at the front end of the cross frame 4, and the alignment sleeve 6 is rotatably installed on the inner ring of the support ring 8 to support the rotation of the alignment sleeve 6.
[0023] The inner ring of the support ring 8 is fixed with the positioning ring, and the outer ring of the alignment sleeve 6 is provided with an arc groove to prevent the alignment sleeve 6 from falling off.
[0024] The gear 7 is vertically aligned with the rack 13, thereby improving the docking accuracy of the gear 7 and the rack 13.
[0025] A plug hole is provided at the top of the U-shaped sliding key 14 away from the supporting ring 8 to facilitate the docking of the positioning bolt 15 with the U-shaped sliding key 14 .
[0026] Working principle: when in use, first put the pipe between the cross frame 4 and the clamp 17, and then pass the external bolts through the cross frame 4 and the two ends of the clamp 17 to obtain circular holes, until the bolts pass through the cross frame 4 and the clamp 17 and connect with the external equipment, so that the installation of the cross frame 4 and the clamp 17 can be completed. Then, the U-shaped sliding key 14 can be moved to the end close to the bolt until the alignment sleeve 6 contacts the bolt. At this time, the sliding rod 10 can be pulled to the end away from the rack 13, so that the rack 13 can be driven to disengage from the gear 7 and release the gear 7. Afterwards, the hexagonal hole 5 is opened in the inner center of the alignment sleeve 6, and the arc groove on the outer ring of the alignment sleeve 6 can be rotated on the positioning ring on the inner ring of the support ring 8, so that the angle of the alignment sleeve 6 can be adjusted, so as to facilitate the alignment of the hexagonal hole 5 with the external bolt. Afterwards, when the hexagonal hole 5 is slidably sleeved to the outer ring of the bolt, the U-shaped sliding key 14 can drive the top end of the socket to be vertically aligned with the positioning bolt 15. At this time, the positioning bolt 15 can be screwed and rotated until The positioning bolt 15 is inserted into the insertion hole at the top of the U-shaped sliding key 14, so that the support ring 8 and the U-shaped sliding key 14 can be positioned and restricted to prevent the alignment sleeve 6 from sliding again. Subsequently, the sliding rod 10 is released, and the elasticity of the return spring 11 can drive the rack 13 to quickly return to its original position until the rack 13 is meshed with the gear 7 again, so that the alignment sleeve 6 can be prevented from rotating again, thereby preventing the external bolts from loosening inside the alignment sleeve 6, completing the work of preventing the external bolts from loosening. Afterwards, when the pipeline between the cross frame 4 and the clamp 17 needs to be disassembled, the sliding rod 10 can be pulled to the end away from the rack 13 until the rack 13 is out of contact with the gear 7, and then the positioning bolt 15 is screwed and rotated until the positioning bolt 15 is removed from the insertion hole at the top of the U-shaped sliding key 14, and then the U-shaped sliding key 14 is pulled to the front end, so that the alignment sleeve 6 can be removed from the outer ring of the external bolt, which is convenient for the alignment sleeve 6 to quickly disengage from the bolt. At this time, the outside personnel can use tools to remove the bolts to complete the work.
