Description

Technical Field

[0001] The utility model relates to the technical field of hooks, in particular to an anti-unhooking lock hook. Background Art

[0002] In hoisting operations, it is critical to hook and lock the fastening points or hanging points of the hoisted objects. In particular, in order to prevent the impact force generated by the irregular swing of the hoisted objects from causing the fastening points to fall out of the hook body, a high-strength locking mechanism is required, and the various entities of this mechanism can effectively prevent the associated hanging with other objects to ensure the safety and reliability of the hoisting process. Traditional hoisting hook devices often have problems such as loose locking, weak impact bearing of the safety device, easy damage, and exposed springs that are easy to hang with other objects, which are difficult to meet the high requirements of modern hoisting operations.

[0030] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0031] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0032] Please refer to Figure 1The overall structure diagram of the utility model anti-unhooking lock hook includes a hook body and an elastic safety card, wherein the hook body is a pear-shaped structure as a whole, and has a hook head 1 and a hook body 2. The hook head 1 is provided with a hook groove 3 for hanging the object to be hung, and the top of the hook body 2 is provided with a circular hanging hole 12 for installation with a sling or a sling. The hook body 2 is provided with a mounting hole 4 for connecting the elastic safety card on the side close to the hook groove 3.

[0033] Please combine Figure 1-2 As shown, in this embodiment, the elastic insurance card includes a card body 5, a groove 51 is set at the top of the card body 5, a pair of connecting plates 52 are set at both ends of the groove 51, and the pair of connecting plates 52 are clamped on both sides of the mounting hole 4 by the pin 6 to form a hinged structure. The bottom end of the card body 5 extends toward the opening of the hook groove 3 to just close the notch of the hook groove 3. A blind hole 53 extending along the axial direction of the card body 5 is set in the groove 51, and a spring return mechanism is installed in the blind hole 53.

[0034] Among them, the spring return mechanism includes a top shaft 7 and a spring 8. A pressure block 9 connected to the spring 8 is arranged at the bottom end of the top shaft 7. The top end of the top shaft 7 is bent to form a flat jaw 10. The bottom end of the spring 8 is against the bottom of the blind hole 53. The top end of the jaw 10 is stuck in the slot 11 on the side of the mounting hole 4 close to the hook slot 3. When the top shaft 7 rotates along the slot 11, the spring 8 is in a compressed state to generate a rebound force.

[0035] When the present embodiment is in use, the card body 5 is squeezed toward the inner side of the hook body, and the card body 5 rotates with the latch pin 6 as the center. At the same time, the flat jaw 10 at the top end of the top shaft 7 abuts against the card slot 11 of the hook body of the hook body and rotates along the card slot 11. The spring 8 is squeezed and compressed. When the gap between the hook body and the card body 5 is large enough to accommodate the fastening point or hanging point of the suspended object, the suspended object is placed in. After that, no external force is applied. The spring automatically rebounds due to its own resilience, and the card body 5 rotates back to abut against the hook body of the hook body to close the hook slot 3, thereby limiting the fastening point or hanging point of the suspended object. The principle of releasing the suspended object is the same as that of placing the suspended object.

[0036] To sum up, the anti-unhooking lock hook designed by the utility model has a spring locking mechanism that cooperates closely with the hook body, which can effectively prevent the impact force generated by the irregular swing of the hoisted object from causing the fastening point or hanging point to fall out of the hook groove during the hoisting process, and the various solid parts of the hook body can effectively prevent the associated hanging with other objects, thereby ensuring safe and reliable hoisting operations.

[0037] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
