[0003] In the existing safety and anti-slip mold hook, the safety buckle position may have insufficient rotational force of the torsion spring when used for a long time, so it needs to be improved. Utility Model Content
[0004] The utility model aims to solve the problem that the safety buckle in the prior art cannot well resist the hook after a long time, and proposes the following technical solutions:

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0018] like Figures 1 to 3 As shown, a safe and non-slip mold hook comprises a lifting ring 1, a hook 2 is fixedly connected to one side of the surface of the lifting ring 1, an adjusting device 4 is rotatably connected to one side of the lifting ring 1, safety buckles 3 are rotatably connected to both sides of the adjusting device 4, and a shock absorbing device 5 is fixedly connected to the bottom of one side of the safety buckle 3; when the user uses the device, the safety buckle 3 is first pressed downward and the object to be hung is placed into the hook 2, the adjusting device 4 is used to adjust the rotational force of the torsion spring 402, and the shock absorbing device 5 is used to reduce the collision damage of objects to the safety buckle 3.
[0019] like Figures 1 to 3 As shown, the adjusting device 4 includes a rotating rod 401, a torsion spring 402 is sleeved on the outer side of the rotating rod 401, one end of the torsion spring 402 is inserted into one side of the rotating rod 401, one end of the side of the rotating rod 401 is fixedly connected to a plurality of blocks 403, one end of the rotating rod 401 is fixedly connected to a limiting plate 404, and the other end of the rotating rod 401 is fixedly connected to a knob 405; after the torsion spring 402 has been used for a long time, the rotational force of the torsion spring 402 may become smaller, and the safety buckle 3 cannot be pressed against the inner side of the hook 2 again. The rotating rod 401 can be pulled upward first to a height greater than the height of the block 403, and then the rotating rod 401 can be rotated to adjust the rotational force of the torsion spring 402. When the rotational force of the torsion spring 402 reaches the standard, the block 403 is pushed back into the groove for fixation, so that the safety buckle 3 can continue to be used.
[0020] like Figures 1 to 2As shown, the shock absorbing device includes a spring 501, one end of the spring 501 is fixedly connected to the safety buckle 3, and the other end of the spring 501 is fixedly connected to a shock absorbing plate 502; during use, the suspended object will hit the safety buckle 3 when it is constantly swinging. At this time, adding a shock absorbing device 5 to the edge of the safety buckle 3 can effectively resist the impact force of the object on the safety buckle 3 and reduce damage to the safety buckle 3.
[0021] like Figure 3 As shown, the rotational force of the torsion spring 402 on the rotating rod 401 is smaller than the bearing force of the clamping block 403, so as to prevent the rotational force of the torsion spring 402 from breaking the clamping block 403.
[0022] like Figures 2 to 3 As shown, the material of the shock absorbing plate 502 is rubber, and the material of the clamping block 403 is metal. The shock absorbing plate 502 is made of rubber, which can effectively reduce collision damage, and the clamping block 403 made of metal is less likely to be broken.
[0023] like Figures 2 to 3 As shown, the rotation of the rotating rod 401 drives the torsion spring 402 to rotate; one end of the torsion spring 402 is inserted into the rotating rod 401, and the rotation force of the torsion spring 402 increases when the rotating rod 401 rotates.
[0024] Working principle:
[0025] When the user uses the device, first press the safety buckle 3 downward and put the object to be hung into the hook 2. During use, the hung object will hit the safety buckle 3 when it keeps swinging. At this time, adding a shock absorbing device 5 at the edge of the safety buckle 3 can effectively resist the impact force of the object on the safety buckle 3 and reduce damage to the safety buckle 3. After the torsion spring 402 has been used for a long time, the rotation force of the torsion spring 402 may become smaller, and the safety buckle 3 cannot be pushed to the inside of the hook 2 again. The rotating rod 401 can be pulled upward first to a height greater than the block 403, and then the rotating rod 401 can be rotated to adjust the rotation force of the torsion spring 402. When the rotation force of the torsion spring 402 reaches the standard, the block 403 is pushed back into the groove for fixation, so that the safety buckle 3 can continue to be used.
[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
