[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a multi-key management structure for a mechanical lock, including a key management box 1 and a fixing mechanism 2 for fixing the keys. The fixing mechanism 2 is located in the inner cavity of the key management box 1. Several sets of adjustment frames 3 are bolted to the inner cavity of the key management box 1. The inner cavity of the adjustment frame 3 is rotatably connected to a screw 4 through a damping shaft. The friction of the damping shaft is greater than the weight of the moving seat 6. The surface of the screw 4 is provided with a self-locking thread structure. One end of the screw 4 passes through the adjustment frame 3 and is fixedly connected to a button block 5. The inner cavity of the adjustment frame 3 is also provided with a moving seat 6. The surface of the moving seat 6 is provided with a through hole. A threaded sleeve 8 is inserted and fixed in the inner cavity of the through hole of the moving seat 6. The inner cavity of the threaded sleeve 8 is threadedly connected to the screw 4. The surface of the moving seat 6 is also provided with a hook 7 for hanging keys.

[0026] In use, first open the key management box 1, then place the bottom of the key into the fixing mechanism 2. The fixing mechanism 2 will then fix the bottom of the key. Next, rotate the knob 5 to drive the screw 4 to rotate. Through the threaded connection between the screw 4 and the threaded sleeve 8, the screw 4 drives the moving seat 6 to move through the threaded sleeve 8. The moving seat 6 drives the hook 7 to move, thus adjusting the distance between the hook 7 and the fixing mechanism 2. Hang the hanging ring at the top of the key on the hook 7. Finally, close the key management box 1 for storage and management. This method allows the key storage cabinet to store and manage keys of different lengths, improving its applicability and convenience.

[0027] The surface of the movable seat 6 is provided with a movable hole, and a slide rod 9 is slidably inserted into the inner cavity of the movable hole. Both sides of the slide rod 9 are fixedly connected to the inner cavity of the adjusting frame 3. The movable hole and the slide rod 9 can support both sides of the movable seat 6, preventing the movable seat 6 from rotating when the threaded sleeve 8 moves, thus improving the stability of the movable seat 6 when it moves within the inner cavity of the adjusting frame 3.

[0028] The fixing mechanism 2 includes a concave seat 21, which is fixedly connected to the inner cavity of the key management box 1 by bolts. The inner cavity of the concave seat 21 is provided with a clamping structure for clamping the key. The bottom end of the key is placed in the inner cavity of the concave seat 21, and then the clamping structure is controlled to cooperate with the concave seat 21 to clamp and fix the bottom end of the key, thereby fixing the position of the bottom end of the key and improving the stability of the key in the key management box 1.

[0029] The clamping structure includes a clamping plate 22 located in the inner cavity of the concave seat 21. A support rod 24 is integrally formed on the surface of the clamping plate 22, and a spring 25 is sleeved on the outer surface of the support rod 24. The other end of the support rod 24 passes through the concave seat 21 and is provided with a pull ring 23. When the key is placed into the concave seat 21, the pull ring 23 is pulled first to drive the clamping plate 22 to move through the support rod 24, so that the clamping plate 22 compresses the spring 25. When the bottom end of the key is placed into the concave seat 21, the pull ring 23 is released, so that the spring 25 is released and rebounds to push the clamping plate 22 to move toward the key surface, so as to cooperate with the concave seat 21 to compress and fix the key.

[0030] Both the surface of the clamping plate 22 and the inner wall of the concave seat 21 are bonded with cushioning pads. The cushioning pads prevent the clamping plate 22 from clamping the concave seat 21 with excessive force and damaging the surface of the key.

[0031] The inner cavity of the concave seat 21 is provided with a support groove 10, and a support block 11 is slidably connected to the inner cavity of the support groove 10. The support block 11 is T-shaped and the top end of the support block 11 is fixedly connected to the bottom end of the clamping plate 22. Through the cooperation of the support block 11 and the support groove 10, the clamping plate 22 can be assisted to move within the concave seat 21, so as to avoid the angle of the clamping plate 22 shifting when it moves.

[0032] It also includes a transparent label box 12, which is bolted to the inner cavity of the key management box 1. The transparent label box 12 is strip-shaped. By setting the transparent label box 12, the code of the corresponding key can be written on the label card. When the user is looking for the key, he / she can retrieve the key by asking for the key code, which provides convenience for key management.

[0033] The inner cavity of the key management box 1 is integrally formed with a partition 13. The partition 13 is provided with several sets. The key codes on the labels inside the transparent label box 12 can be separated by the partition 13, making it convenient for users to view them.

[0034] In practical use: First, open the key management box 1, then pull the pull ring 23 to drive the clamping plate 22 to squeeze the spring 25 through the support rod 24, place the bottom end of the key in the concave seat 21, release the pull ring 23 to release the spring 25 and push the clamping plate 22 to move towards the key surface, and the bottom end of the key is clamped and fixed by the cooperation of the concave seat 21 and the clamping plate 22.

[0035] Rotating the knob 5 clockwise causes the screw 4 to rotate, which in turn drives the movable seat 6 upward through the threaded sleeve 8. Rotating the knob 5 counterclockwise causes the movable seat 6 to move downward. Adjusting the position of the movable seat 6 according to the length of the key adjusts the position between the hook 7 and the concave seat 21. Then, hang the key ring on the hook 7 and rotate the screw 4 clockwise again to move the movable seat 6 upward, which works in conjunction with the fixing mechanism 2 to pull and fix the key, preventing it from falling off due to vibration when carried. This solution allows the key storage cabinet to store and manage keys of different lengths, improving its applicability and convenience.

[0036] 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.
