The outer side of the control wheel 401 is provided with two locking grooves that are compatible with the T-shaped rods 802.

[0046] After the control wheel 401 rotates to the right position, the locking spring 801 pushes the T-shaped rod 802 to slide, so that the locking rod 803 is locked in the control wheel 401, so that the control wheel 401 is fixed to prevent it from rotating in other special circumstances;

[0047] The control wheel 401 is formed of two semicircles in one piece, and the ends of the two linkage rods 402 close to the control wheel 401 are both arranged in an arc shape, and the hexagonal holes 404 matched with the outer side of the control wheel 401 are matched with the hexagonal wrench;

[0048] The hexagonal hole 404 is compatible with a hexagonal wrench, so that the cabinet housing 2 can be quickly installed using an installation tool during installation, thereby reducing the use of special tools and improving the versatility of the tools.

[0049] The cabinet shell 2 is also fixedly connected with a mounting plate 9 located in front of the fixing component 4 and the anti-disassembly component 5. The front of the mounting plate 9 is fixedly connected with no less than six hanging components 10. The six hanging components 10 are vertically equidistantly distributed. The front of the mounting plate 9 is provided with a plug hole located outside the hexagonal hole 404. The outside of the plug hole is embedded with a sealing cover 14.

[0050] The sealing cover 14 can seal the jack after the cabinet housing 2 is installed, so as to prevent foreign objects such as keys from falling into the rear side of the mounting plate 9 through the jack, thereby affecting the normal transmission of the mechanism on the rear side of the mounting plate 9;

[0051] The hook assembly 10 includes a fixing box 1001, the back of which is fixedly connected to the front of the mounting plate 9, a fixing shaft 1002 arranged in a transverse direction is fixedly connected inside the fixing box 1001, and at least ten hooks 1003 are rotatably connected to the outside of the fixing shaft 1002, one end of which extends to the front of the fixing box 1001, and the backs of the ten hooks 1003 are fixedly connected to balance bars 1004, and the bottoms of the ten balance bars 1004 are clamped with counterweights 1005 of the same weight as the hooks 1003, and the tops of the ten balance bars 1004 are fixedly connected to pressure bars 1006, and the tops of the ten pressure bars 1006 are spherical, and the top wall of the inner cavity of the fixing box 1001 is fixedly connected to release switches 1007 adapted to the ten pressure bars 1006, and the ten release switches 1007 are electrically connected to external warning devices;

[0052] The counterweight 1005 can disengage the pressing rod 1006 from the release switch 1007 when there is no key hanging on the hook 1003, so as to avoid false alarm triggering;

[0053] The front of the cabinet shell 2 is rotatably connected to a cabinet door 11 that can be locked and closed. The inner side of the cabinet shell 2 is fixedly connected to a sealing rubber ring 12 that is arranged around the outer side of the cabinet door 11. A switch state detection module is arranged inside the cabinet door 11, and the switch detection module is electrically connected to an external warning device.

[0054] The sealing rubber ring 12 has a certain elasticity and memory, so that after the cabinet door 11 is closed and locked, it can fill the gap between the cabinet door 11 and the cabinet shell 2 with its own elasticity and memory, thereby improving the sealing of the inner cavity of the cabinet door 11 and the cabinet shell 2, and preventing moisture and other water vapor from entering the cabinet shell 2 and causing the keys stored inside to rust;

[0055] The front of the reinforcing plate 6 is provided with countersunk holes adapted to the eight expansion bolts 3. The first clamping rod 406 and the second clamping rod 505 are extended to the inner side of the bottom shell 1 at one end and are both rounded. The length of the reinforcing plate 6 is less than the length of the cabinet shell 2.

[0056] The length of the reinforcing plate 6 is shorter than that of the cabinet shell 2. After the cabinet shell 2 and the bottom shell 1 are assembled, the cabinet shell 2 can cover the reinforcing plate 6 and the collision screws for installing the bottom shell 1, thereby reducing the exposure of the moving parts and improving the anti-disassembly capability.

[0057] The hook 1003 is arranged in a U shape, and an anti-drop groove 13 having a diameter larger than the inner diameter of the hook 1003 is provided on the inner side of the hook 1003;

[0058] The anti-slip groove 13 can further improve the reliability of the connection between the key and the hook 1003, and prevent the key from being detached from the hook 1003 due to vibration of the cabinet housing 2 caused by slight impact or the like.

[0059] Working principle:

[0060] Step 1: During installation, the expansion bolts 3, the reinforcing plate 6 and the bottom shell 1 are sequentially assembled, and the bottom shell 1 is fixed to the wall or other fixed position by the expansion bolts 3 to complete the fixing of the bottom shell 1;

[0061] Step 2: Insert the cabinet shell 2 into the bottom shell 1, pry open the sealing cover 14, insert an external hexagonal wrench into the inner hexagonal hole 404 and rotate it, so that the control wheel 401 rotates, and the control wheel 401 pushes the linkage rod 402 to move, so that the linkage rod 402 drives the push block 405 to squeeze the squeeze block 503 to move, and the squeeze block 503 can push the second clamping rod 505 through the cabinet shell 2 and into the bottom shell 1 through the push rod 502. At the same time, the first clamping rod 406 also passes through the cabinet shell 2 and is inserted into the bottom shell 1. When the first clamping rod 406 and the second clamping rod 505 are inserted into the bottom shell 1, the anti-loosening spring 701 can push the clamping block 702 to insert into the first clamping rod The first and second clamping rods 406 and 505 are limited in position in the clamping groove of the rod 406 or the second clamping rod 505. After the control wheel 401 rotates and pushes the first clamping rod 406 to a predetermined position, the locking spring 801 pushes the T-shaped rod 802 to drive the locking rod 803 to clamp the control wheel 401, and the control wheel 401 is clamped to prevent it from rotating again. At the same time, the linkage rod 402 is limited by the control wheel 401 to form a secondary lock with the anti-loosening component 7 to improve the anti-disassembly capability. Finally, the sealing cover 14 is buckled on the mounting plate 9 to seal the mounting plate 9. By hiding the movable parts, the possibility of the cabinet shell 2 being disassembled and moved is reduced;

[0062] Step 3: When the key needs to be stored, unlock the cabinet door 11 and open it, and hang the key on the hook 1003. The weight of the key presses the hook 1003 to rotate via the fixed shaft 1002, so that the pressure rod 1006 presses the release switch 1007. At this time, the release switch 1007 transmits an electrical signal to an external warning device. After closing and locking the cabinet door 11, the switch detection module in the cabinet door 11 transmits an electrical signal to an external warning device.

[0063] Step 4: When the cabinet door 11 is not opened and the key is detached from the hook 1003, the counterweight 1005 drives the balance bar 1004 to make the hook 1003 tilt upward. At this time, the pressure rod 1006 is detached from the release switch 1007. At this time, an electrical signal is sent to the external warning device to generate an alarm. The cross-linkage of the two warning devices improves the safety of key storage.
