DETAILED DESCRIPTION
[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a hook bolt with an anti-loosening structure, comprising a winding wheel 1, a winding rope 2 is wound around the interior of the winding wheel 1, a fixing hook 3 is fixedly installed at the end of the winding rope 2, a hook 5 is clamped on the fixing hook 3, a connecting rod 4 is fixedly connected to the outer wall of the hook 5, an adjusting box 6 is arranged on the side of the connecting rod 4, a connecting rope 7 passes through the interior of the adjusting box 6, the connecting rope 7 is fixedly connected to the end of the connecting rod 4, an anti-falling mechanism 8 is arranged inside the adjusting box 6, and a fixing mechanism 9 is arranged inside the adjusting box 6.
[0022] In this embodiment, an anti-falling mechanism 8 is provided inside the adjusting box 6. When the connecting rod 4 pulls the connecting rope 7, the sleeve 83 in the anti-falling mechanism 8 rotates around the rotating rod 81, so that the sleeve 83 and the adjusting box 6 are in a parallel state. When the winding rope 2 is loose, the winding rope 2 can continue to be kept taut by rotating the twisting sleeve 83, thereby preventing the clamping connection between the fixed hook 3 and the hook 5 from falling off.
[0023] In this embodiment, a fixing mechanism 9 is provided inside the adjusting box 6. By engaging the clamping block 96 in the fixing mechanism 9 into the inside of the clamping slot 97, the extrusion plate 92 can stably press the connecting rope 7 to prevent loosening. At the same time, by pushing the elastic plate 95 to release the clamping block 96, the extrusion rod 91 can drive the extrusion plate 92 to reset, thereby facilitating the adjustment of the position of the connecting rope 7.
[0024] The above-mentioned anti-falling mechanism 8 includes a rotating rod 81, which is rotatably connected to the inner wall of the adjusting box 6. A sleeve plate 83 is fixedly installed at the end of the rotating rod 81. The sleeve plate 83 is set to be inclined relative to the adjusting box 6. A wiring groove 84 is opened inside the sleeve plate 83, and a connecting rope 7 runs through the wiring groove 84. The sleeve plate 83 can be rotated around the rotating rod 81 by pulling the connecting rope 7 by the connecting rod 4, so that the sleeve plate 83 and the adjusting box 6 are in a parallel state. The outer wall of the rotating rod 81 is fixedly connected to one end of the torsion spring 82, and the other end of the torsion spring 82 is elastically connected to the inner wall of the adjusting box 6. The sleeve plate 83 can be rotated by the elastic force of the torsion spring 82, so that the winding rope 2 continues to remain in a taut state, thereby preventing the clamping connection between the fixing hook 3 and the clamping hook 5 from falling off.
[0025] The fixing mechanism 9 includes an extrusion rod 91, which passes through the interior of the sleeve plate 83. A push plate 94 is fixedly installed at the end of the extrusion rod 91. By pushing the push plate 94, the extrusion rod 91 can be driven to move toward the interior of the sleeve plate 83. An extrusion plate 92 is fixedly installed at the end of the extrusion rod 91. By driving the extrusion plate 92 to move toward the interior of the sleeve plate 83 by the extrusion rod 91, the connecting rope 7 can be compressed. The extrusion plate 92 is located inside the wiring groove 84, and an arc groove is provided on the extrusion plate 92. The outer wall of the extrusion rod 91 is sleeved with a return spring 93. One end of the return spring 93 is fixedly connected to the outer wall of the extrusion rod 91, and the other end of the return spring 93 is connected to the outer wall of the sleeve plate 83. The wall is fixedly connected, and the elastic force of the reset spring 93 can make the extrusion rod 91 drive the extrusion plate 92 to reset. An elastic plate 95 is fixedly installed on the outer wall of the push plate 94, and a clamping block 96 is fixedly installed on the outer wall of the elastic plate 95. The elastic force of the elastic plate 95 can make the clamping block 96 be clamped into the inside of the clamping groove 97, so that the extrusion plate 92 can stably press the connecting rope 7. One end of the clamping block 96 is set to an arc shape, and the arc-shaped outer wall of the clamping block 96 is squeezed by the sleeve plate 83, which can make the clamping block 96 drive the elastic plate 95 to deform. A clamping groove 97 is opened on the outer wall of the sleeve plate 83, and the clamping groove 97 is located on the side of the clamping block 96, and the size of the clamping groove 97 is adapted to that of the clamping block 96.
[0026] In this embodiment, the connecting rope 7 is first adjusted to a suitable position, and then the pushing plate 94 is pushed to drive the extrusion rod 91 to move toward the inside of the sleeve plate 83, and then the extrusion rod 91 drives the extrusion plate 92 to move toward the inside of the sleeve plate 83 to compress the connecting rope 7. At the same time, the pushing plate 94 drives the block 96 on the outer wall of the elastic plate 95 to move toward the slot 97, and the sleeve plate 83 squeezes the arc-shaped outer wall of the block 96, so that the block 96 drives the elastic plate 95 to deform, and finally the block 96 continues to move toward the slot 97, and the elastic force of the elastic plate 95 makes the block 96 snap into the inside of the slot 97, so that the extrusion plate 92 stably compresses the connecting rope 7, and the winding wheel is started at this time. 1 is used to reel in the winding rope 2, and through the engagement between the fixed hook 3 and the hook 5 and the pulling of the connecting rope 7 by the connecting rod 4, the sleeve plate 83 is rotated around the rotating rod 81, thereby making the sleeve plate 83 and the adjusting box 6 in a parallel state. When the winding rope 2 is loose during use, the sleeve plate 83 can be rotated by the elastic force of the torsion spring 82, thereby keeping the winding rope 2 in a taut state, preventing the fixed hook 3 and the hook 5 from being engaged and falling off. After use, the winding rope 2 is unwound by the winding wheel 1, and the engagement of the clamping block 96 is released by pushing the elastic plate 95, and the extrusion rod 91 drives the extrusion plate 92 to reset by the elastic force of the reset spring 93, so as to facilitate the adjustment of the position of the connecting rope 7.
[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
