Description
Technical Field
[0001] This utility model specifically relates to the technical field of anti-detachment hook structures, and more specifically to a novel anti-detachment hook structure. Background Technology
[0002] In the field of lifting operations, the hook is the core component connecting the lifting equipment and the load, and its safety performance is of paramount importance. Traditional hooks, in actual use, are prone to detachment due to factors such as load swaying and external impacts, leading to serious accidents such as load falling, equipment damage, and even personal injury. Although some hooks are equipped with simple anti-detachment structures, they have many shortcomings: such as poor connection stability of the anti-detachment components, making them prone to loosening under vibration; limited anti-detachment range, making it difficult to cope with irregular swinging of loads under complex working conditions; and cumbersome installation and operation, affecting lifting efficiency. Utility Model Content

By installing the anti-detachment mechanism with the hook body, the overall structure of the hook is enhanced and the anti-detachment performance is greatly improved. At the same time, it has convenient operation and wide applicability, so as to solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A novel anti-detachment hook structure, including
[0006] The hook body is equipped with an anti-detachment mechanism.
[0007] The anti-detachment mechanism includes an anti-detachment lifting lug connecting rod, with anti-detachment lifting lugs symmetrically installed at both ends of the anti-detachment lifting lug connecting rod. Each anti-detachment lifting lug has a reinforcing block on its inner side, and each anti-detachment lifting lug has a circular fixing screw hole at its other end.
[0008] One side of the fixing screw hole on one of the anti-detachment lugs is connected to one end of the locking screw rod.

A locking nut is provided on the other side of the washer. Both the locking nut and the washer are threaded to the other end of the locking screw rod.
[0009] As a further technical solution of this utility model, the locking screw part also has a through-hole, which is located between the fixing screw holes on the anti-detachment lugs that are symmetrically arranged, and the through-hole is located at the front end of the hook body.
[0010] As a further technical solution of this utility model, the upper end of the hook body is connected to the hook and the ring, and a rotating shaft is provided on the rear side of the upper end of the hook body, and the inner side of the rotating shaft is rotatably connected to the anti-detachment lug connecting rod.
[0011] As a further technical solution of this utility model, a connecting ear plate is provided on the front side of the upper end of the hook body, and anti-detachment limiting pins are fixedly installed on both sides of the connecting ear plate.
[0012] As a further technical solution of this utility model, the anti-detachment limiting pin and the auxiliary anti-detachment baffle are symmetrically connected by connecting holes at the rear end, and the front end of the auxiliary anti-detachment baffle is connected to the front end of the hook body; an anti-detachment elastic retaining spring is provided at the connection between the auxiliary anti-detachment baffle and the anti-detachment limiting pin.
[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7 In this embodiment of the utility model, a novel anti-detachment hook structure includes a hook body 1, on which an anti-detachment mechanism 2 is installed;
[0029] The anti-detachment mechanism 2 includes an anti-detachment lifting lug connecting rod 21, with anti-detachment lifting lugs 22 symmetrically installed at both ends of the anti-detachment lifting lug connecting rod 21. Each anti-detachment lifting lug 22 has a reinforcing block on its inner side, and each anti-detachment lifting lug 22 has a circular fixing screw hole 23 at its other end.
[0030] One side of the fixing screw hole 23 on one of the anti-detachment lugs 22 is connected to one end of the locking screw 24. The screw part of the locking screw 24 passes through the fixing screw holes 23 on both anti-detachment lugs 22. One side of the fixing screw hole 23 on the other anti-detachment lug 22 is connected to the washer 25. The other side of the washer 25 is provided with a locking nut 26. Both the locking nut 26 and the washer 25 are threaded to the other end of the locking screw 24.
[0031] The locking screw 24 also has a connecting hole 14 through it. The connecting hole 14 is located between the fixing screw holes 23 on the anti-detachment lugs 22 which are symmetrically arranged, and the connecting hole 14 is located at the front end of the hook body 12.
[0032] The upper end of the hook body 12 is connected to the hook ring 11, and a rotating shaft 13 is provided on the rear side of the upper end of the hook body 12. The inner side of the rotating shaft 13 is rotatably connected to the anti-detachment lug connecting rod 21.
[0033] By adopting the above technical solutions, the inner reinforcing block of the anti-slip lug 22 improves the local strength, and the locking screw 24, locking nut 26 and washer 25 work together to ensure that the anti-slip mechanism is firmly connected to the hook body 12; the design of the rotating shaft 13 and the anti-slip elastic snap ring 17 makes the connection between the components both flexible in rotation and stable in elastic return, adapting to the dynamic working conditions of lifting operations.
[0034] The anti-detachment mechanism is installed using conventional connecting parts such as locking screws 24 and locking nuts 26. The auxiliary anti-detachment baffle 18 automatically resets with the help of the anti-detachment elastic snap ring 17. No complicated operation procedures are required, and the operation difficulty of lifting operations is not increased. This facilitates workers to quickly attach and lift heavy objects, thereby improving work efficiency.
[0035] In this embodiment, a connecting ear plate 15 is provided on the front side of the upper end of the hook body 12, and anti-detachment limiting pins 16 are fixedly installed on both sides of the connecting ear plate 15.
[0036] The anti-detachment limiting pin 16 and the auxiliary anti-detachment baffle 18 are symmetrically connected by connecting holes at the rear end, and the front end of the auxiliary anti-detachment baffle 18 is connected to the front end of the hook body 12; the auxiliary anti-detachment baffle 18 and the anti-detachment limiting pin 16 are provided with an anti-detachment elastic snap ring 17.
[0037] By adopting the above technical solution, when in use, the anti-detachment lug 22 and the auxiliary anti-detachment baffle 18 work together to build an anti-detachment barrier from different parts of the hook body 12, covering the hook opening and surrounding area, effectively preventing the heavy object from falling off the hook due to shaking, impact, etc., and greatly reducing the risk of detachment.
[0038] The working principle of this utility model is as follows: the anti-detachment lugs 22 at both ends of the anti-detachment lug connecting rod 21 are connected to the hook body 12 through locking screws 24, washers 25, and locking nuts 26. The structural strength is enhanced by reinforcing blocks to form the first anti-detachment protection.
[0039] The anti-detachment limiting pin 16 on the connecting ear plate 15 is rotatably connected to the auxiliary anti-detachment baffle 18. The anti-detachment elastic snap spring 17 provides elastic force, so that the auxiliary anti-detachment baffle 18 fits against the end of the hook body 12 and closes the hook opening area. When the heavy object is hung into the hook, the auxiliary anti-detachment baffle 18 is squeezed open. After the heavy object is in place, it is reset under the action of the anti-detachment elastic snap spring 17. Together with the anti-detachment lifting ear 22, it restricts the heavy object from falling out from different directions.
[0040] When in use, the anti-detachment lug 22 and the auxiliary anti-detachment baffle 18 work together to build an anti-detachment barrier from different parts of the hook body 12, covering the hook opening and surrounding area, effectively preventing the heavy object from falling off the hook due to shaking, impact, etc., and greatly reducing the risk of detachment.
[0041] The inner reinforcing block of the anti-slip lug 22 enhances local strength, and the locking screw 24, locking nut 26, and washer 25 work together to ensure a stable connection between the anti-slip mechanism and the hook body 12; the design of the rotating shaft 13 and the anti-slip elastic snap ring 17 allows the connection between the components to have both rotational flexibility and elastic return stability, adapting to the dynamic working conditions of lifting operations.
[0042] The anti-detachment mechanism is installed using conventional connecting parts such as locking screws 24 and locking nuts 26. The auxiliary anti-detachment baffle 18 automatically resets with the help of the anti-detachment elastic snap ring 17. No complicated operation procedures are required, and the operation difficulty of lifting operations is not increased. This facilitates workers to quickly attach and lift heavy objects, thereby improving work efficiency.
