Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0031] This embodiment can provide an anti-slip function when the hook is hoisted by installing the anti-slip frame on the hook head. The anti-slip component is installed on the hook head through a rotating shaft. The anti-slip main rod can be pressed against the bottom of the hook head opening during the use of the hook head, thereby preventing the hanging part from detaching from the hook head. The anti-slip component is provided with a magnet and a reinforcing rod, which can improve the tightness of the connection between the anti-slip component and the contact point of the hook head and the pressure bearing capacity of the anti-slip component itself, so that the anti-slip frame is not easy to shake during use, has good and stable anti-slip ability, and further improves the practicality of the entire device. The specific implementation is as follows:
[0032] like Figures 1 to 5As shown, a hook head device with an anti-slip structure includes a hook head 1 and an anti-slip frame 2. The hook head 1 is provided with a hook head opening 4 for the entry of hanging parts. The middle part of the hook head 1 is connected with the anti-slip frame 2. The anti-slip frame 2 includes an anti-slip component 6, a rotating shaft 7 and a limiting frame 8. The limiting frame 8 is fixedly installed on the side of the top of the anti-slip component 6. The inner side of the top of the anti-slip component 6 is installed with a rotating shaft 7. The rotating shaft 7 is rotatably connected to the hook head 1. The anti-slip component 6 includes two anti-slip plates 9 arranged in parallel and an anti-slip main rod 12 connected to the bottom of the two anti-slip plates 9. A plurality of reinforcing rods 11 are arranged between the two anti-slip plates 9. A magnet 15 is arranged inside the anti-slip main rod 12. The anti-slip frame 2 is installed on the hook head 1 to provide an anti-slip function when the hook head 1 is hoisted. The anti-slip component 6 is installed on the hook head 1 through the rotating shaft 7. The anti-slip main rod 12 can be pressed against the bottom of the opening of the hook head 1 during the use of the hook head 1, thereby preventing the hanging part from detaching from the hook head 1. The magnet 15 and the reinforcing rod 11 are arranged on the anti-slip component 6 to improve the tightness of the connection between the anti-slip component 6 and the contact point of the hook head 1 and the pressure-bearing capacity of the anti-slip component 6 itself, so that the anti-slip frame 2 is not easy to shake during use, has good and stable anti-slip ability, and further improves the practicality of the entire device.
[0033] A pin hole 18 is provided on the hook head 1 at a position above the hook head opening 4, and a rotating shaft 7 is inserted and connected in the pin hole 18. The two ends of the rotating shaft 7 are respectively welded to the top ends of the two anti-slip plates 9 and can drive the two anti-slip plates 9 to rotate along the circumferential direction of the pin hole 18. The rotating shaft 7 can pass through the pin hole 18 to connect the hook head 1 and the anti-slip frame 2.
[0034] An anti-slip main rod 12 is welded between the bottom ends of the two anti-slip plates 9. The lower surface of the anti-slip main rod 12 is formed with an inclined plane that matches the position below the hook head opening 4. Through the anti-slip main rod 12, the hook head 1 can be supported by the inclined plane.
[0035] A magnet 15 is installed inside the inclined plane, and a magnetic block 17 matched with the magnet 15 is installed below the hook head opening 4. With the cooperation of the magnet 15 and the magnetic block 17, the anti-drop main rod 12 can be magnetically attracted to prevent it from falling.
[0036] The inner surface of the hook head 1 is provided with an anti-skid layer 16, and the inner edge of the hook head 1 is installed with two symmetrically arranged limiting protrusions 5. The limiting protrusions 5 arranged on the inner side of the hook head 1 can assist the anti-slip frame 2 to limit the hanging parts and prevent the hanging parts from shifting and detaching. The anti-skid layer 16 can increase the friction between the hook head 1 and the hanging parts.
[0037] The limiting frame 8 is a U-shaped steel pipe, and a counterweight groove 10 is installed on the upper surface of the limiting frame 8 away from the rotating shaft 7. A detachable counterweight block is placed in the counterweight groove 10. Through the setting of the counterweight groove 10 on the limiting frame 8, the counterweight groove 10 can be added as needed, which can keep the limiting frame 8 downward and drive the anti-detachment component 6 connected to it to keep upward, thereby resisting the inner edge of the hook head 1, thereby enhancing the locking and limiting effect.
[0038] The length of the anti-slip plate 9 is greater than the opening size of the hook head opening 4, and the length of the anti-slip plate 9 is less than the length of the limiting frame 8. The length can be adjusted according to the load of the hook head 1 and the opening size of the hook head 1, mainly to ensure the anti-slip effect. The length of the limiting frame 8 is 1.3-1.5 times that of the anti-slip plate 9, and the width is equal.
[0039] The outside of the anti-slip main rod 12 is provided with a buffer sleeve 13, and the outer surface of the buffer sleeve 13 is provided with a wear-resistant layer 14. The buffer sleeve 13 provided inside the anti-slip main rod 12 can reduce the extrusion force generated by the anti-slip main rod 12 and the hook head 1. At the same time, the wear-resistant layer 14 is provided on the outer surface of the anti-slip main rod 12, which can improve the wear resistance and the service life of the anti-slip main rod 12, and further improve the durability of the entire device.
[0040] Three reinforcing rods 11 are welded in sequence between the two anti-slip plates 9, and the surface of the rotating shaft 7 is provided with a wear-resistant coating. With the cooperation of the three reinforcing rods 11, the strength of the anti-slip assembly 6 can be fully improved, and the wear-resistant coating can improve the wear resistance of the rotating shaft 7.
[0041] The material of the anti-drop assembly 6 is stainless steel, the material of the limiting frame 8 is threaded steel, and the row of the hook head 1 is provided with a connecting block 3. Through the connecting block 3, the lifting equipment can be connected, which is convenient for the use of the entire hook head 1.
[0042] Working principle: The anti-slip frame is installed on the hook head, which can be rotated to a certain extent and provide an anti-slip function when the hook head is hoisted. The anti-slip component is installed on the hook head through a rotating shaft, and a counterweight block can be set in the counterweight slot of the limit frame to generate downward pressure, so that the anti-slip component and the anti-slip plate rotate upward and move the anti-slip main rod upward, so that when the hook head is in use, the anti-slip main rod is against the bottom of the hook head opening and prevents the hanging part from detaching from the hook head. A magnet is set on the anti-slip component, which can attract the magnetic block on the hook head through magnetic attraction, thereby improving the tightness of the connection between the anti-slip component and the contact point of the hook head. At the same time, multiple reinforcing rods are set between the anti-slip plates to improve the overall strength of the anti-slip component and the pressure-bearing capacity of the anti-slip component itself, making the anti-slip frame During use, it is not easy to shake and has good and stable anti-slip ability, which further improves the practicality of the entire device. The limiting protrusion arranged on the inner side of the hook head can assist the anti-slip frame to limit the hanging parts and prevent the hanging parts from shifting and detaching. By setting the counterweight groove on the limiting frame, the counterweight groove can be added as needed, so that the limiting frame can be kept downward and drive the anti-slip assembly connected to it to keep upward, thereby resisting the inner edge of the hook head, thereby enhancing the locking and limiting effect. By setting the buffer sleeve inside the anti-slip main rod, the extrusion force generated by the mutual squeezing of the anti-slip main rod and the hook head can be reduced. At the same time, a wear-resistant layer is arranged on the outer surface of the anti-slip main rod to improve the wear resistance and the service life of the anti-slip main rod, thereby further improving the durability of the entire device.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
