[0028] Reference Figures 1 to 5 The embodiment of the present application provides an automatically tightened sliding bolt nut, including: an anchor 100; a gasket 200, which is arranged above the anchor 100, and the gasket 200 is rotatably connected to the anchor 100; a torsion spring 300, which is arranged between the anchor 100 and the gasket 200, and the torsion spring 300 is provided with a first end 310 and a second end 320, and the first end 310 and the second end 320 are respectively connected to the anchor 100 and the gasket 200; a bolt 400, which is sequentially passed through the gasket 200 and the torsion spring 300 and is threadedly connected to the anchor 100, and the bolt 400 is provided with a compression spring 410, and the compression spring 410 is pressed against the gasket 200.

[0029] By setting a rotational connection between the gasket 200 and the anchor 100, and providing a torsion spring 300 between the gasket 200 and the anchor 100, and the compression spring 410 presses the gasket 200, a certain external force is applied to the gasket 200 in advance during use, so that the gasket 200 is away from the anchor 100 and rotates relative to the anchor 100. At this time, the compression spring 410 is in a compressed state, and the torsion spring 300 has a certain torque. Then the gasket 200 is released, and the gasket 200 will move under the action of the resetting of the compression spring 410 and the torsion spring 300, thereby realizing automatic tightening with the profile, without the need to apply external force for tightening for the second time, the structure is simple, the operation is easy, the labor intensity is reduced, and the installation efficiency is improved.

[0030] The anchor 100 is provided with a first connector 110, the gasket 200 is provided with a second connector 210, the first connector 110 is rotatably connected to the second connector 210, the compression spring 410 is passed through the gasket 200 to press the second connector 210, the torsion spring 300 is provided in the first connector 110, and the two ends of the torsion spring 300 are respectively connected to the anchor 100 and the second connector 210. By providing the first connector 110 and the second connector 210, it is convenient to realize the rotation connection between the gasket 200 and the anchor 100, and the production and processing are simple, thereby improving the work efficiency.

[0031] Of course, the first connecting member 110 and the second connecting member 210 can also be directly formed integrally with the anchor 100 and the gasket 200, respectively, to make installation easier.

[0032] Reference Figures 1 to 4 It can be imagined that the inner wall of the first connecting member 110 is provided with a slide groove 120, the slide groove 120 is provided with a clamping position 130, and the outer wall of the second connecting member 210 is provided with a convex rib 220, and the convex rib 220 can move along the slide groove 120 and be embedded in the clamping position 130. Pull and rotate the gasket 200, so that the gasket 200 drives the second connecting member 210 to move, and the convex rib 220 is separated from the clamping position 130 and is located in the slide groove 120. At this time, the torsion spring 300 has a certain torsion force; then loosen the gasket 200, and the gasket 200 drives the second connecting member 210 to move under the action of the compression spring 410 and the torsion spring 300 to reset, so that the convex rib 220 moves along the slide groove 120 and returns to the clamping position 130 again, thereby realizing automatic fastening with the profile. The convex rib 220 cooperates with the slide groove 120 to facilitate the rotation connection between the first connecting member 110 and the second connecting member 210, thereby improving the stability of the rotation reset.

[0033] Further, the slide groove 120 is arranged around the inner wall of the first connecting member 110, and the clamping position 130 is provided with two groups, and the two groups of clamping positions 130 are symmetrically arranged on the slide groove 120. By symmetrically arranging two groups of clamping positions 130 on the slide groove 120, when the torsion spring 300 rotates toward either side, it can ensure that the convex rib 220 is smoothly embedded in the clamping position 130, thereby avoiding the situation that the torsion spring 300 is incorrectly installed, making the installation easier. It can be imagined that each group of clamping positions 130 includes a first clamping position and a second clamping position, and there is an angle between the first clamping position and the second clamping position, and the depth of the first clamping position is greater than the depth of the second clamping position. By providing two clamping positions 130 with different depths, it can be applied to profiles with different installation heights, thereby expanding the scope of application. Furthermore, there are two convex ribs 220, and the two convex ribs 220 correspond to the first clamping position and the second clamping position one by one. By the two convex ribs 220 being connected with the two latching positions 130 at the same time, the stability of the connection between the first connecting member 110 and the second connecting member 210 can be further improved, and the structure is simple and the operation is easy.

[0034] Reference Figures 1 to 5 In some embodiments, a mounting groove 140 is provided at the bottom of the first connector 110, and the first end 310 extends out of the first connector 110 along the mounting groove 140, and the first end 310 is bent downward to form a bent portion 330, and the bent portion 330 abuts against the side wall of the anchor 100, so that the first end 310 is clamped with the anchor 100. By providing the mounting groove 140 on the first connector 110, the position of the first end 310 can be limited to prevent the torsion spring 300 from loosening and affecting its effectiveness, and then the bent portion 330 abuts against the anchor 100 to achieve clamping, which has a simple structure and is easy to operate. The second connector 210 is provided with a mounting hole 230, and the second end 320 is inserted into the mounting hole 230. By adopting the above structure, the installation of the torsion spring 300 is facilitated, and the operation is simple.

[0035] It is easy to understand that the bottom of the first connector 110 is provided with a first buckle 150, the mounting groove 140 is located next to the first buckle 150, and the anchor 100 is provided with a first buckle 160, and the first buckle 150 is engaged with the first buckle 160. The first buckle 150 cooperates with the first buckle 160 to achieve the engagement of the first connector 110 and the anchor 100, which can prevent the first connector 110 and the anchor 100 from falling off during use, thereby improving the stability of the engagement. Correspondingly, the second connector 210 is provided with a second buckle 240, and the gasket 200 is provided with a second buckle 250, and the second buckle 240 is engaged with the second buckle 250, thereby facilitating the engagement of the second connector 210 and the gasket 200, preventing the second connector 210 and the gasket 200 from falling off during use, thereby improving the stability of the engagement.

[0036] When in use, the bolt 400 is sequentially passed through the gasket 200 and the torsion spring 300 to be threadedly connected with the anchor 100 to form an assembly; then a certain external force is applied to the gasket 200, so that the gasket 200 drives the second connecting member 210 away from the anchor 100, the convex rib 220 disengages from the locking position 130 and is located in the slide groove 120, and the compression spring 410 is in a compressed state; at the same time, the gasket 200 is rotated to make the second connecting member 210 rotate relative to the first connecting member 110, the convex rib 220 moves along the slide groove 120, and the torsion spring 300 has a certain torque at this time; then the assembly is clamped onto the profile; finally, the gasket 200 is released, and the gasket 200 drives the second connecting member 210 to move under the cooperation of the compression spring 410 and the torsion spring 300, so that the convex rib 220 moves along the slide groove 120 and returns to the clamping groove again, thereby achieving the fixation of the assembly and the profile. By adopting the above structure, automatic fastening with the profile can be achieved without applying external force for fastening a second time. The structure is simple, the operation is easy, the labor intensity is reduced, and the installation efficiency is improved.
