[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a high-security cabinet door lock, including a cabinet door panel 1. A mounting side panel 11 is fixedly connected to one side of the cabinet door panel 1. A door lock body 3 is fixedly installed on one side of the mounting side panel 11. A support platform 12 is fixedly installed on one side of the mounting side panel 11. The support platform 12 is located directly below the door lock body 3. Sliding grooves 13 are respectively provided on both sides of the door lock body 3. The sliding grooves 13 are fixedly installed on one side of the mounting side panel 11. A slider assembly 21 is slidably connected inside the sliding grooves 13. A protective chamber 2 is fixedly connected to one end of the slider assembly 21. A magnetic positioning assembly 22 is fixedly installed on one end of the inner side of the protective chamber 2. A first magnetic block 111 is fixedly installed on one end of the mounting side panel 11. The magnetic positioning assembly 22 includes a mounting plate 221 and a second magnetic block 222. A mounting groove 223 is opened inside the mounting plate 221. The second magnetic block 222 is fixedly installed inside the mounting groove 223. The mounting plate 221 is fixedly installed on one end of the inner side of the protective chamber 2.

[0024] The specific settings and functions of this embodiment are described below. After the door lock body 3 completes the opening and closing operation of the chassis and cabinet, the protective compartment 2 is pushed down, so that the first magnetic block 111 and the second magnetic block 222 move away from each other, releasing the magnetic attraction. The protective compartment 2 protects the door lock body 3 inside, isolating the door lock body 3 from contact with external corrosive gases, thereby extending the service life of the door lock body 3. The protective compartment 2 is made of polytetrafluoroethylene, which gives it extremely excellent chemical stability. It can withstand the corrosion of almost all strong acids, strong alkalis and strong oxidants, and maintain good performance in high and low temperature environments.

[0025] Example 2: Figure 1 - Figure 4As shown, a high-security cabinet door lock includes a cabinet door panel 1. A mounting side panel 11 is fixedly connected to one side of the cabinet door panel 1. A door lock body 3 is fixedly mounted to one side of the mounting side panel 11. A support platform 12 is fixedly mounted to one side of the mounting side panel 11, positioned directly below the door lock body 3. Slide grooves 13 are provided on both sides of the door lock body 3. The slide grooves 13 are fixedly mounted to one side of the mounting side panel 11. A slider assembly 21 is slidably connected inside the slide grooves 13. A protective chamber 2 is fixedly connected to one end of the slider assembly 21, and a magnetic positioning component is fixedly mounted to one end inside the protective chamber 2. 22. A magnetic block 111 is fixedly installed at one end of the mounting side plate 11. The slider assembly 21 includes a mounting rod 211, a roller 212 and a stop block 213. One end of the mounting rod 211 is fixedly connected to the inside of the protective chamber 2. The roller 212 is rotatably connected to the outside of the other end of the mounting rod 211.

[0026] The overall effect of this embodiment is that when the protective chamber 2 slides downward, it drives the slider assembly 21 to slide inside the slide groove 13. The roller 212 in the slider assembly 21 fits against the inner wall of the slide groove 13, so that the slider assembly 21 does not wobble when sliding inside the slide groove 13, thus improving the stability and continuity of the sliding of the protective chamber 2. In addition, when one end of the protective chamber 2 is about to contact the support platform 12, the sealing strip 25 at one end of the protective chamber 2 will fall into the interior of the sealing groove 121 in the support platform 12, replacing the protective chamber 2 in contact with the support platform 12. At the same time, the sealing strip 25 and the sealing groove 121 cooperate to fill the gap between the protective chamber 2 and the support platform 12, isolating external corrosive gases and further protecting the door lock body 3 from the corrosion of external corrosive gases.

[0027] The usage and working principle of this device are as follows: After the door lock body 3 completes the opening and closing operation of the chassis and cabinet, the protective compartment 2 is pushed down, so that the first magnetic block 111 and the second magnetic block 222 move away from each other, releasing the magnetic attraction. The protective compartment 2 protects the door lock body 3 inside, preventing the door lock body 3 from contacting external corrosive gases. When one end of the protective compartment 2 is about to contact the support platform 12, the sealing strip 25 at one end of the protective compartment 2 will fall into the interior of the sealing groove 121 in the support platform 12, replacing the protective compartment 2 in contact with the support platform 12. At the same time, the sealing strip 25 and the sealing groove 121 cooperate to fill the gap between the protective compartment 2 and the support platform 12.
