[0019] The following is combined with Figure 1-5 The specific implementation methods of the present invention are further described in detail.

[0020] Embodiment 1, the technical solution is that when the present application is in use, two sets of latch locks 7 are arranged on the inner wall of the cabinet 1. Furthermore, in order to increase the connection strength of the lock, more latch locks 7 and components such as trigger devices 6 used in conjunction with the latch locks 7 can be evenly arranged around the door opening 2, thereby forming a multi-point combined locking mechanism to ensure the locking strength of the cabinet 1.

[0021] In this application, the cabinet door 4 is installed at the door opening 2 position of the cabinet body 1 through the hinge 3. When the cabinet door 4 is closed, the cabinet door 4 will interact with the trigger device 6, and then the locking controller 8 will be started through the trigger device 6, and then the locking controller 8 will start the latch lock 7, so that the insertion rod 21 is inserted into the lock sleeve 5, and the cabinet door 4 is locked. When the cabinet door 4 needs to be opened, only the corresponding password needs to be entered through the password unlocking controller 17, and the unlocking controller will act on the latch lock 7, so that the insertion rod 21 is disengaged from the lock sleeve 5, and then the unlocking is completed to facilitate the opening of the cabinet door 4. This application is easy to use and has strong practicality.

[0022] Example 2, based on Example 1, specifically, as shown in the accompanying drawings Figure 2 As shown, at this time the cabinet door 4 is in a locked state. When the cabinet door 4 is in the locked state, the pressing piece 14 and the pressure sensor 15 are in a contact state, and the spring 16 is in a stretched state; when the cabinet door 4 is in the open state, the spring 16 is in a normal extended state, the positions of the trigger rod 12 and the trigger ball 13 are forward relative to when the cabinet door 4 is locked, and the pressing piece 14 and the pressure sensor 15 are in a separated state.

[0023] During use of the present application, when a correct password is input into the password unlocking controller 17, the password unlocking controller 17 is activated and controls the electronic telescopic rod 19 fixedly connected to the card sleeve 18 to retract a set stroke. As the electronic telescopic rod 19 retracts, the connecting rod 20 drives the insertion rod 21 out of the lock sleeve 5, and then the cabinet door 4 can be opened through the handle 24. When the cabinet door 4 is opened, the trigger ball 13 loses the restraint of the cabinet door 4, and then the spring 16 automatically contracts and drives the trigger rod 12 to move forward along the guide sleeve 11, and then the pressing piece 14 will also lose contact with the pressure sensor 15;

[0024] When the cabinet door 4 needs to be locked again, during the process of closing the cabinet door 4, the rear end of the cabinet door 4 will first contact and act on the trigger ball 13. As the cabinet door 4 continues to close, the cabinet door 4 will force the trigger rod 12 to move backward along the guide sleeve 11 on the vertical rod 10 through the trigger ball 13. When the trigger rod 12 moves backward, the spring 16 is stretched. When the cabinet door 4 is fully closed, the pressing piece 14 will also move to the extreme position with the trigger rod 12 and contact the pressure sensor 15 on the bracket 9. Then the pressure sensor 15 senses the pressure signal from the pressing piece 14 and transmits it to the locking controller 8. The locking controller 8 will control the electronic telescopic rod 19 to extend the set stroke. As the electronic telescopic rod 19 extends, the connecting rod 20 together with the insertion rod 21 will move synchronously toward the lock sleeve 5, so that the insertion rod 21 is inserted into the lock sleeve 5 to complete the locking of the cabinet door 4.

[0025] In the third embodiment, based on the second embodiment, the front end of the bracket 9 abuts against the rear end of the cabinet door 4, thereby facilitating the complete closing of the cabinet door 4 and the alignment of the insertion rod 21 with the locking sleeve 5. A guide block 22 is arranged on the inner wall of the guide sleeve 11, which cooperates with the guide groove 23 on the trigger rod 12, restricting the trigger rod 12 to move only along the axial direction of the guide sleeve 11.
