[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1-3A lock hook control structure applicable to mechanical combination lock boxes includes a housing 1, a lock hook body 2, and an unlocking component. The housing 1 includes a bottom cover 3, a middle frame 4, a top cover 5, and a lock cylinder assembly 6. The middle frame 4 has a storage cavity that runs vertically through the center. The bottom cover 3 is provided on the bottom wall of the middle frame 4, and the top cover 5 is provided on the top wall of the middle frame 4. One end of the top cover 5 is hinged to the middle frame 4, and the other end of the top cover 5 is provided with the lock cylinder assembly 6 connected to the middle frame 4.

[0022] A guide frame 7 is provided at one end of the middle frame 4 near the unlocking component. A guide groove for guiding the unlocking component is provided in the middle part of the guide frame 7. The unlocking component includes a spring 8 and a spring sheet 9. The spring 8 is arranged in two symmetrical sets. The upper and lower sides of the spring 8 are respectively connected to the spring sheet 9 and the bottom cover 3. The locking hook body 2 is U-shaped. The two free ends of the locking hook body 2 pass through the middle frame 4 and the guide groove. The two free ends of the locking hook body 2 are provided with a tapered surface 10. The two free ends of the locking hook body 2 are also provided with a positioning groove that matches the upper part of the spring sheet 9. The end of the spring sheet 9 away from the locking hook body 2 is also provided with a pressure plate 11. The middle part of the guide frame 7 is provided with an inverted U-shaped groove that matches the pressure plate 11.

[0023] The bottom cover 3, middle frame 4, and top cover 5 enclose and seal the storage cavity. When unlocking the mechanical combination box, the user must first ensure that the password is entered correctly, making the lock cylinder assembly 6 operable (this part of the password recognition and the opening of the lock cylinder assembly 6 are controlled by the overall mechanical system of the combination box; here, the focus is mainly on the lock hook control structure). After the top cover 5 is opened, the user presses the pressure plate 11 at the end of the spring 9 away from the lock hook body 2. After the pressure plate 11 is subjected to force, it drives the spring 9 to move downward against the elastic force of the spring 8. Since there is a positioning groove below the spring 9 that matches the spring 8, the spring 8 can stably provide support and reset force for the spring 9. During the upward movement of the spring 9, its upper part will gradually separate from the positioning groove of the two free ends of the lock hook body 2. The lock hook body 2 is U-shaped, with the two free ends passing through the middle frame 4 and the guide groove. The guide groove in the middle part of the guide frame 7 provides precise guidance for the movement of the unlocking element, ensuring the accurate movement trajectory of the spring 9 and the lock hook body 2. When the spring piece 9 is completely separated from the positioning groove, the locking hook body 2 is no longer restricted by the spring piece 9, and its two free ends can move freely because they are no longer stuck, thereby achieving unlocking;

[0024] When locking the combination lock, align the two free ends of the lock hook body 2 with the positions of the middle frame 4 and the guide groove, and insert it. The tapered surfaces 10 on the two free ends of the lock hook body 2 serve as guides, making it easier to insert into the corresponding positions. As the lock hook body 2 is inserted, its two free ends will gradually approach the spring piece 9.

[0025] The leather sleeve 12 fitted onto the lock hook body 2 and the rainproof plugs 13 at both free ends provide protection. The leather sleeve 12, located on the outside of the middle frame 4, prevents dust and debris from entering the gap between the middle frame 4 and the lock hook body 2, thus avoiding interference with the normal operation of the lock hook. The rainproof plugs 13, fitted against the middle frame 4, effectively prevent rainwater from entering, protecting the internal mechanical structure and preventing rust and damage. The gasket 14 located below the bottom cover 3 provides cushioning and protection, reducing friction between the bottom cover 3 and the placement surface, preventing damage to the bottom cover 3; it also reduces the impact of vibration on the internal structure. The top cover 5 has a notch adapted to the unlocking button of the lock cylinder assembly 6, facilitating user operation of the lock cylinder assembly 6 for locking and unlocking, improving ease of use.
