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.

[0016] Please see Figure 1-6 This utility model provides the following technical solution: a key protection structure for a combination lock cabinet, comprising: a combination lock cabinet body 10 and a protective cover 11. The protective cover 11 is installed on the front end face of the combination lock cabinet body 10. The protective cover 11 is a cuboid structure with an opening at the bottom. The palm can be inserted into the interior of the protective cover 11 through the opening at the bottom of the protective cover 11. An accommodating groove 12 is provided inside the protective cover 11. An electronic keyboard 13 is installed inside the accommodating groove 12. By striking the electronic keyboard 13, a password can be entered to open the combination lock cabinet. A display screen 14 is provided on the front end face of the protective cover 11. The display screen 14 can display whether the combination lock cabinet body 10 is in the unlocked or closed state. This is prior art and will not be described in detail here.

[0017] The front surface of the protective cover 11 is provided with number icons, which correspond to the numbers on the electronic keyboard 13, making it easy for users to identify the input area. The protective cover 11 is provided with protective components 2 spaced on the left and right sides. The protective components 2 can open or close the receiving slot 12 to protect the electronic keyboard 13.

[0018] The protective component 2 includes a drive plate 21 and a protective plate 22. The drive plate 21 and the protective plate 22 are slidably installed at the opening of the receiving groove 12. The protective cover 11 has strip grooves 15 at both ends. The drive plate 21 and the protective plate 22 can extend out of the protective cover 11 through the strip grooves 15, thereby opening the receiving groove 12. At this time, the user can operate the electronic keyboard 13 to input the password.

[0019] The protective cover 11 has a sliding groove 16 inside, and sliders 161 are spaced apart on the left and right sides inside the sliding groove 16. The sliders 161 are connected to the top of their corresponding drive plate 21 and protective plate 22, so that the drive plate 21 and protective plate 22 can slide smoothly along the sliding groove 16.

[0020] Please see Figure 1-3 The protective cover 11 has a transmission gear 23 rotatably installed inside. The protective cover 11 has a transmission component inside. The drive plate 21 can drive the protective plate 22 to move relative to or towards each other through the transmission component and the transmission gear 23, thereby realizing the opening and closing of the receiving groove 12.

[0021] The transmission component includes a drive rack 24 and a transmission rack 25, which are slidably mounted inside the protective cover 11. The teeth of the drive rack 24 and the transmission rack 25 are arranged opposite each other. The drive rack 24 and the transmission rack 25 are respectively connected to the drive plate 21 and the protective plate 22, and both the drive rack 24 and the transmission rack 25 mesh with the transmission gear 23.

[0022] When the user needs to enter a password, they push the drive plate 21 by hand, which causes the drive rack 24 to slide outward along the slide groove 16. The drive rack 24 drives the transmission gear 23 to rotate, and then the transmission gear 23 and the transmission rack 25 mesh together to push the protection plate 22 to move synchronously, so that the drive plate 21 and the protection plate 22 slide in opposite directions, thereby opening the opening of the receiving groove 12. At this time, the electronic keyboard 13 is exposed, and the user can enter the password.

[0023] Please see Figure 1 and Figure 5 A first connecting block 211 is installed at the bottom of the drive plate 21, and the first connecting block 211 is connected to the drive rack 24. A second connecting block 221 is installed at the bottom of the protection plate 22, and the second connecting block 221 is connected to the transmission rack 25. The first connecting block 211 has a limiting groove that runs through the left and right sides and is adapted to the transmission rack 25. The drive plate 21 drives the drive rack 24 to move through the first connecting block 211, and the transmission rack 25 drives the protection plate 22 to slide synchronously through the second connecting block 221. The limiting groove is used to prevent the first connecting block 211 and the transmission rack 25 from interfering with each other during the movement.

[0024] A fixing block 26 is installed on the inner wall of the protective cover 11. A U-shaped handle 27 is installed on the back of the drive plate 21. The fixing block 26 has a slot 271 that matches the U-shaped handle 27 at one end facing the U-shaped handle 27. A drive hole 28 is provided inside the protective cover 11. A drive shaft 281 is rotatably installed inside the drive hole 28. The drive shaft 281 is connected to the transmission gear 23. A torsion spring 29 is provided inside the drive hole 28. One end of the torsion spring 29 is connected to the inner wall of the drive hole 28, and the other end of the torsion spring 29 is connected to the transmission gear 23.

[0025] When a password is required, the drive plate 21 is pushed by the U-shaped handle 27, causing the first connecting block 211 to drive the drive rack 24 to slide outward. The drive rack 24 rotates by meshing with the transmission gear 23, and the transmission gear 23 then drives the transmission rack 25 to move inward and outward. In turn, the second connecting block 221 drives the protection plate 22 to slide synchronously, thereby opening the receiving slot 12.

[0026] Simultaneously, the U-shaped handle 27 gradually engages with the slot 271 of the fixing block 26, positioning the drive plate 21 and ensuring structural stability during password input. At this time, the torsion spring 29 is compressed and stores elastic potential energy. After input is complete, the U-shaped handle 27 is removed from the slot 271, and the torsion spring 29 releases its stored elastic potential energy, driving the transmission gear 23 to rotate in the opposite direction. This causes the transmission rack 25 and the drive rack 24 to move in opposite directions, allowing the drive plate 21 and the protection plate 22 to slide synchronously relative to each other, thereby closing the opening of the receiving slot 12. The electronic keyboard 13 is then re-covered, ensuring the safety and dust prevention of the device when not in use.

[0027] Please see Figure 1-6 Working principle: When in use, the user puts their hand into the protective cover 11 and applies a pushing force through the U-shaped handle 27 to push the drive plate 21 to slide outward in the horizontal direction. The drive plate 21 drives the drive rack 24 to move synchronously. The drive rack 24 rotates by meshing with the transmission gear 23. The transmission gear 23 then drives the transmission rack 25 to move, thereby driving the protective plate 22 to move in opposite directions, realizing the opening of the receiving slot 12. At the same time, the U-shaped handle 27 is inserted into the slot 271 of the fixing block 26 to complete the positioning of the drive plate 21.

[0028] After the password is entered, the U-shaped handle 27 is pulled out of the slot 271, releasing the limit of the drive plate 21. The torsion spring 29 then releases its elastic potential energy, and the transmission gear 23 rotates in the opposite direction, driving the drive rack 24 and the transmission rack 25 to retract synchronously. The drive plate 21 and the protection plate 22 slide relative to each other under the transmission action and return to their initial positions until the receiving slot 12 is completely closed, and the electronic keyboard 13 is tightly covered.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
