Description

Technical Field

[0001] This utility model relates to the field of anti-slip hook technology, specifically an anti-slip hook structure. Background Technology

[0002] Anti-slip hooks are safety devices used to prevent objects from slipping or falling off. They are typically designed as components with a curved hook-like structure. By hooking onto an object or fixed point, they provide additional gripping force or stability, thereby preventing objects from slipping, shifting, or falling off when subjected to force or vibration. Anti-slip hooks are widely used in construction, machinery, transportation, outdoor sports, and other fields to secure tools, equipment, ropes, safety belts, etc., ensuring operational safety and equipment stability.

[0003] Existing anti-slip hooks typically employ anti-slip textures or pads to enhance friction with objects, thereby effectively improving anti-slip performance. These designs significantly enhance safety when lifting or securing objects, preventing them from sliding or falling. However, this friction-dependent design also has limitations. In actual use, continuous friction occurs between the anti-slip textures or pads and the object's surface. As usage time increases, these textures or pads gradually wear down, becoming smooth and reducing friction. This wear not only reduces the anti-slip effect of the hook but also affects its reliability in subsequent use. Therefore, an anti-slip hook structure is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slip hook structure to solve the problem that existing anti-slip hooks usually adopt anti-slip textures or anti-slip pads in their design to enhance the friction between the hook and the object. These anti-slip textures or anti-slip pads will gradually wear down, causing their surfaces to become smooth and the friction to weaken. This wear not only reduces the anti-slip effect of the anti-slip hook, but may also affect its reliability in subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-slip hook structure includes a hook assembly. A buffer moving component and an anti-slip component are installed inside the hook assembly. The hook assembly includes a hook body with an external through hole, a movable hole, an arc-shaped channel, and an inclined groove on its inner side. The buffer moving component includes a positioning plate. An extension column is fixedly connected to the bottom end of the positioning plate, and an extension plate is fixedly connected to the bottom end of the extension column. A rubber sealing ring is fixedly connected to the outer side of the extension plate, and a spring is fixedly connected to the bottom end of the extension plate. The bottom end of the spring is fixedly connected to the lower end of the movable hole. The anti-slip component slides inside the inclined groove.

[0007] As a further optimization of this utility model, the left and right ends of the hook body are both fixedly connected to reinforcing plates, and the bottom end of the hook body is fixedly connected to an outer ring.

[0008] As a further optimization of this utility model, the external through hole penetrates one end of the hook body, the external through hole is connected to the movable hole, the movable hole is cylindrical in shape, and there are multiple movable holes.

[0009] As a further optimization of this utility model, the external through hole and the movable hole are both vertical structures, the movable hole, the arc-shaped channel and the inclined groove are connected, and the arc-shaped channel is arc-shaped.

[0010] As a further optimization of this utility model, the inclined groove is an inclined structure that extends through one end of the hook body, and the inclined groove is formed by two cylinders of different diameters.

[0011] As a further optimization of this utility model, the following features are provided: the extension column and the expansion plate are both cylindrical in shape; the upper end of the extension column extends outward from the outer side of the external through hole; a gap is provided between the positioning plate and the hook body; and the positioning plate is arc-shaped.

[0012] As a further optimization of this utility model, the structure of the anti-slip component is the same as that of the extension column, the extension plate and the rubber sealing ring. Hydraulic oil is provided inside the movable hole, the arc-shaped channel and the inclined groove. The anti-slip component is an inclined structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, by setting up a hook assembly, a buffer moving assembly, and an anti-slip assembly, the device, through a unique hydraulically driven limiting structure, avoids direct friction between the anti-slip hook and the object before and during lifting, thereby significantly reducing wear of the anti-slip components caused by friction. This design not only extends the service life of the anti-slip hook, but also ensures its reliability and anti-slip performance in long-term use, improving the safety and stability of the equipment.

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.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] An anti-slip hook structure includes a hook assembly 1, a buffer moving assembly 2 and an anti-slip assembly 3 installed on the inner side of the hook assembly 1. The hook assembly 1 includes a hook body 11, and the inner side of the hook body 11 has an external through hole 12, a movable hole 13, an arc-shaped channel 14 and an inclined groove 15. The buffer moving assembly 2 includes a positioning plate 21, an extension column 22 fixedly connected to the bottom end of the positioning plate 21, an extension plate 23 fixedly connected to the bottom end of the extension column 22, a rubber sealing ring 24 fixedly connected to the outer side of the extension plate 23, and a spring 25 fixedly connected to the bottom end of the extension plate 23. The bottom end of the spring 25 is fixedly connected to the lower end of the movable hole 13. The anti-slip assembly 3 slides on the inner side of the inclined groove 15.

[0028] As a further implementation of this solution, the left and right ends of the hook body 11 are fixedly connected with reinforcing plates 4, and the bottom end of the hook body 11 is fixedly connected with an outer ring 5. Through the above settings, the reinforcing plates 4 enhance the overall structural strength and stability of the device, and can better withstand the tension and gravity during lifting, ensuring the reliability of the device during use. The outer ring 5 can be connected to external equipment.

[0029] As a further implementation of this solution, the external through hole 12 penetrates one end of the hook body 11 and is connected to the movable hole 13. The movable hole 13 is cylindrical in shape and there are multiple movable holes 13. Both the external through hole 12 and the movable hole 13 are vertical structures. The movable hole 13, the arc-shaped channel 14 and the inclined groove 15 are connected. The arc-shaped channel 14 is arc-shaped. With the above settings, the multiple external through holes 12 are designed vertically, which facilitates the up and down movement of the buffer moving component 2. This design allows hydraulic oil to flow between the movable hole 13 and the inclined groove 15, which improves the response speed and stability of the hydraulic system. At the same time, the design of multiple movable holes 13 can evenly distribute the force and enhance the anti-slip effect of the device.

[0030] As a further implementation of this solution, the inclined groove 15 is an inclined structure. The inclined groove 15 passes through one end of the hook body 11. The opening shape of the inclined groove 15 is two cylinders with different diameters. Through the above setting, it can better adapt to the tilt angle of the object, provide more accurate limiting and anti-slip effects, and enhance the adaptability and reliability of the device.

[0031] As a further implementation of this solution, both the extension column 22 and the expansion plate 23 are cylindrical. The upper end of the extension column 22 extends outward from the outer side of the external through hole 12. A gap is provided between the positioning plate 21 and the hook body 11. The positioning plate 21 is arc-shaped. The structure of the anti-slip component 3 is the same as that of the extension column 22, the expansion plate 23, and the rubber sealing ring 24. Hydraulic oil is provided inside the movable hole 13, the arc-shaped channel 14, and the inclined groove 15. The anti-slip component 3 is an inclined structure. Through the above settings, when lifting, the extension column 22 and the expansion plate 23 are moved downward through the external through hole 12, which can squeeze the hydraulic oil inside the movable hole 13. This allows the anti-slip component 3 to move flexibly under the action of the hydraulic oil and extend into the interior of the inclined groove 15, closely fitting the object and providing a limiting effect. The inclined structure of the anti-slip component 3 can better adapt to the tilt angle of the object, further enhancing the anti-slip effect.

[0032] Workflow: When preventing object slippage on the hook column, open the latch of the hook body 11, hang the object inside the hook body 11, and simultaneously ensure the object is in contact with the top of the positioning plate 21. Initially, the extension column 22 protrudes from the outside of the outer through hole 12, and the upper end of the anti-slip component 3 is flush with the upper end of the inclined groove 15. During lifting, the entire device will move upward. Due to the weight of the object, it will press against the positioning plate 21. At this time, the positioning plate 21 will drive the extension column 22, the expansion plate 23, and the rubber sealing ring 24 to move downward. The expansion plate 23 compresses the spring 25, causing the spring 25 to deform. The rubber sealing ring 24 seals the space between the expansion plate 23 and the hook body 11, preventing hydraulic oil from overflowing from the movable hole 13. When the bottom end of the positioning plate 21 is in contact with the hook body 11, a gap is created between the bottom end of the expansion plate 23 and the bottom end of the movable hole 13. Simultaneously, as the expansion plate 23 moves downward, multiple expansion plates 23 simultaneously push the hydraulic oil inside multiple movable holes 13 to flow. The hydraulic oil inside the movable holes 13 will pass through... The arc-shaped channel 14 enters the connected inclined groove 15, and under the pressure of hydraulic oil, it can push the anti-slip component 3 to move outward, causing the anti-slip component 3 to extend out of the inclined groove 15. At this time, the anti-slip component 3 is in contact with the object, and the limiting action of the anti-slip component 3 can prevent the object from sliding, thus achieving the purpose of anti-slip. After the work is completed, the object is removed from the hook body 11, and under the action of the spring 25, the extension column 22 and the positioning plate 21 are pushed upward, so that the anti-slip component 3 can be stored back into the inclined groove 15 for easy reuse. The setting of the reinforcing plate 4 enhances the strength of the device. Based on the above principles, when the device is lifting an object, it prevents the object from sliding by blocking the object from moving on the hook body 11. With this setting, the anti-slip component 3 used for limiting will not contact the object before lifting and when installing the object, avoiding the generation of friction. After lifting, the object is relatively stable, thus greatly reducing the probability of friction between the anti-slip component 3 and the object, ensuring the service life of the device.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
