Description

Technical Field

[0001] This utility model relates to the field of mechanical locking technology, and in particular to a self-locking spring hook. Background Technology

[0002] In the existing technology, mechanical locking hooks are widely used for suspension connections in scenarios such as lighting equipment, pipeline facilities, and curtain wall installation. Their structure usually consists of a metal hook body and a locking ring, and is used to complete hoisting, fixing or quick connection operations. They are characterized by compact structure and adaptability to multi-angle connections.

[0003] In practical use, most mechanical locks are elastic sheet pressing or spiral tightening structures, lacking a stable and reliable spring-loaded mechanism. This results in the need for manual operation when opening or closing, low efficiency of repeated loading and unloading, and the hooks failing to automatically reset or clamping securely. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing mechanical lock hooks lack an efficient and stable spring-loaded locking structure, which affects ease of use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a self-locking spring hook, including a hook body, a groove is provided on the top of the hook body, a hook guide post is slidably arranged in the groove, two spring chambers are provided in the middle of the hook body, and spring one and spring two are arranged in each of the two spring chambers, the bottom of the hook guide post is abutted against spring two, the hook guide post is slidably connected to the hook body, the top of the hook guide post is abutted against the bottom of the pressing component, a lock body actuator is flexibly connected to one side of the hook guide post, and the lock body actuator is fixedly arranged in the spring chamber of the hook body, the bottom end of spring two is sleeved on the support mechanism, and the support mechanism is located at the bottom end of the spring chamber.

[0006] As a further improvement of this utility model, the pressing component is provided with a frustum-shaped buckle cylinder structure, with a through groove in the center, and is slidably sleeved on the hook body. The bottom end of the pressing component is provided with a pressing actuating mechanism, which is set as an inclined abutment plate at the through groove below the pressing component.

[0007] As a further improvement of this utility model, the lock body actuator is configured as a limiting tongue structure parallel to the hook body, and the bottom is configured as a hook-shaped plate that slopes outward. The outer side of the hook-shaped plate is lock body surface one, and the inner side is lock body surface two.

[0008] As a further improvement of this utility model, the support mechanism is snapped onto the bottom end of the spring chamber and has an L-shaped rod structure. A spring limiting mechanism is also fixedly connected to the top of the support mechanism, and the spring limiting mechanism is a columnar body.

[0009] As a further improvement of this utility model, the hook guide post is configured as a rod-shaped structure parallel to the hook body, and the top of the hook guide post is configured as a conical toothed buckle, and a guide post surface is provided on the outer side of the toothed buckle. A guide post boss is fixed at the bottom of the hook guide post, and the top of the guide post boss is configured as an outwardly inclined guide post surface. A spring mounting mechanism is fixedly connected to the bottom of the guide post boss, and the spring mounting mechanism is configured as a cylinder for the top of the second spring to be sleeved.

[0010] As a further improvement of this utility model, a suspension hole is provided at the tail of the hook body.

[0011] The beneficial effects of this utility model are as follows: By setting a spring chamber and support mechanism inside the hook body, and combining the coordinated operation of spring one and spring two, a stable and elastic reset function of the hook guide post is achieved. In particular, the conical toothed buckle structure and the pressing component set at the top of the hook guide post enable the device to quickly achieve automatic locking and unlocking during use, eliminating the need for frequent manual adjustments and greatly improving the operating efficiency of the hook. At the same time, the setting of the lock body actuator, through the limiting tongue structure, ensures stability and anti-loosening ability during the locking process, solving the problems of weak clamping and poor automatic reset of traditional hooks, and is suitable for various scenarios requiring efficient suspension and repeated loading and unloading.

The bottom end of the pressing component 1 is provided with a pressing actuator 11, which is set as an inclined abutment plate at the through groove below the pressing component 1; used to fasten with the hook guide post 5.

[0024] As attached Figure 2 As shown, the lock body actuator 41 is configured as a limiting tongue structure parallel to the hook body 4, and the bottom is configured as a hook-shaped plate that slopes outward. The outer side of the hook-shaped plate is lock body surface one 411, and the inner side is lock body surface two 412.

[0027] Working principle: In specific implementation, this utility model,

[0028] Opening-Limiting Process: Using one hand, press down on the pressing component 1. The pressing actuator 11 at the bottom of the pressing component 1 presses down on the guide post surface 51 at the top of the hook guide post 5. The guide post boss 53 presses down on the lock body surface 411 of the lock body actuator 41. At the same time, the spring mounting mechanism 54 presses down on the second spring 6, compressing it. The lock body actuator 41 rebounds, and the pressing actuator 11 continues to press down on the second guide post surface 52. Simultaneously, the hook guide post 5 continues to move, and the spring mounting mechanism 54 continues to compress the second spring 6. The pressing actuator 11 releases its downward pressure. Due to the rebound of the second spring 6, the hook guide post 5 rebounds. After the guide post boss 53 returns to the lock body surface 412, its rebound is restricted.

[0029] Springback-closing process: When the external object presses down on the guide post surface 51, the guide post boss 53 disengages from the lock body actuator 41 because the spring is not fully limited laterally. The external object continues to move. After losing the pressure from the external object, the hook guide post 5 returns to its original position under the elastic force of the spring 6, thereby achieving the closure of the upper opening of the hook body 4.
