[0013] Compared with the prior art, the present utility model provides an automatic detachment hook, which has the following beneficial effects:

[0014] 1. In the automatic detachment hook, a spring conduit is provided inside the connecting counterweight plate. A connecting steel wire rope is provided at the left end position of the spring conduit. A hook connecting plate is provided at the end position of the connecting steel wire rope. The hook connecting plate is connected to the left side surface position of the hook body. The automatic detachment hook pulls up the hook body through the spring conduit to open the hook body for lifting heavy objects. According to the self-weight of the lifted object, the hook body is closed. After the lifting is completed, the hook body loses the self-weight of the object and automatically opens. After being improved by the present utility model, it can be automatically detached without manual operation, which improves the safety and efficiency to a certain extent. Since it is a self-detaching hook, the hook load is small, and thus the practicability of the hook in use can be effectively improved.

[0015] 2. In the automatic detachment hook, a connecting bearing column is provided at the middle position of the end groove of the hook body. A middle connecting shaft is provided inside the connecting bearing column. The middle connecting shaft can rotate along the connecting bearing column. A contact auxiliary roller is provided at the middle position of the middle connecting shaft. The contact auxiliary roller is located at the middle section of the middle connecting shaft and is an integral mechanism with the middle connecting shaft. A moving slope clamping block is provided at the upper side position of the middle connecting shaft. The outer end position of the moving slope clamping block has a structure with a slope facing upward. An internal spring body is provided at the end position where the moving slope clamping block contacts the hook body. The moving slope clamping block is connected to the hook body through the internal spring body. Because when the hook is used to lift items, it is very easy to be unable to hook normally due to the direct friction with the top of the hook, which easily affects the use efficiency. After being improved by the present utility model, the friction at its top can be reduced, and the smoothness of hooking and unhooking can be improved to a certain extent, and thus the practicability of use can be effectively improved.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1-4 shown, an automatic detaching hook, including a connecting counterweight plate 6 and a hook body 3 arranged at the bottom position of the connecting counterweight plate 6; a spring conduit 2 is arranged at the internal position of the connecting counterweight plate 6, a connecting steel wire rope 5 is arranged at the left end position of the spring conduit 2, a hook connecting plate 4 is arranged at the end position of the connecting steel wire rope 5, and the hook connecting plate 4 is connected to the left side surface position of the hook body 3. The automatic detaching hook pulls up the hook body 3 through the spring conduit 2 to achieve the purpose of opening the hook body 3 by lifting heavy objects, closes the hook body 3 according to the self-weight of the lifted object, and after the lifting is completed, the hook body 3 loses the self-weight of the object and automatically opens. After being improved by the present utility model, it can be automatically detached without manual operation, improving the safety and editability to a certain extent. Because of its self-detaching hook, the hook load is small, and thus the practicability of the hook in use can be effectively improved.

[0023] As Figure 1As shown, a hook connecting rotating shaft 8 is provided at the upper end position of the hook body 3. The hook body 3 is rotatably connected to the connecting counterweight plate 6 through the hook connecting rotating shaft 8. A lifting hook release 1 is provided at the upper side position of the connecting counterweight plate 6. The lifting hook release 1 is rotatably connected to the connecting counterweight plate 6 through a hook release connecting rotating shaft 7 provided at the bottom end position thereof. The connection of the hook body 3 to the connecting counterweight plate 6 through the hook connecting rotating shaft 8 can facilitate the rotation of the hook body 3 for convenient unhooking.

[0024] As Figure 4 shown, the hook body 3 is made of high-strength alloy steel material. A groove is provided at the end position of the hook body 3. A connecting bearing column 9 is provided at the middle position of the end groove of the hook body 3. A middle connecting shaft 10 is provided inside the connecting bearing column 9. The middle connecting shaft 10 can rotate along the connecting bearing column 9. A contact auxiliary roller 13 is provided at the middle position of the middle connecting shaft 10. The contact auxiliary roller 13 is located at the middle section position of the middle connecting shaft 10 and is an integral structure with the middle connecting shaft 10. A moving slope clamping block 12 is provided at the upper side position of the middle connecting shaft 10. Because when the hook is lifting an object, it is very easy to be unable to hook the object normally due to the friction force directly with the top of the hook, which easily affects the use efficiency. After the improvement of the present utility model, the friction force at its top can be reduced, and the smoothness of hooking and unhooking can be improved to a certain extent, thereby effectively improving the practicability of use.

[0025] As Figure 4 shown, the outer end position of the moving slope clamping block 12 has a structure with a slope facing upwards. A connecting built-in spring body 11 is provided at the end position where the moving slope clamping block 12 contacts the hook body 3. The moving slope clamping block 12 is connected to the hook body 3 through the built-in spring body 11. During installation, only need to squeeze the moving slope clamping block 12 by the connecting bearing column 9. After being squeezed, the moving slope clamping block 12 will generate a lateral component force and move laterally. After the connection of the bearing column 9 is completed, the moving slope clamping block 12 will reset due to the action of the connecting built-in spring body 11 to limit the connecting bearing column 9, which is convenient for the staff to install and disassemble, and thus can effectively improve the work efficiency of the staff.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
