DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 to Figure 7 As shown, this embodiment proposes a cabinet with an anti-theft function, including a base 1, a cabinet body 2 is fixedly connected to the top of the base 1, a cabinet door 3 is hinged on one side of the cabinet body 2, a door lock 4 opened by a key is fixedly installed on one end of the cabinet door 3, a lock seat 5 that is slidably matched with a lock tongue of the door lock 4 is fixedly connected to the inner wall of the cabinet body 2, an interlocking mechanism 6 is arranged on one side of the lock seat 5, and the interlocking mechanism 6 includes a movable rod 61, the movable rod 61 passes through the side wall of the lock seat 5, and the movable rod 61 slides with the side wall of the lock seat 5 The movable rod 61 is dynamically connected, one end of the movable rod 61 is provided with a pushing piece 62 which drives the movable rod 61 to slide under the action of the lock tongue of the door lock 4, the other end of the movable rod 61 is hinged with a connecting rod 63, the inner wall of the cabinet body 2 is fixedly connected with a fixing seat 64, the fixing seat 64 is slidably connected with a limiting rod 65 which passes through the fixing seat 64, the bottom end of the limiting rod 65 is hinged with a connecting rod 63, the bottom end of the connecting rod 63 is hinged with the other end of the movable rod 61, and the inner side of the cabinet door 3 is provided with a docking piece 66 which slidably cooperates with the limiting rod 65.

[0026] The key can be used to make the lock tongue of the door lock 4 cooperate with the lock seat 5, which makes the pushing piece 62 drive the movable rod 61 to slide, and the connecting rod 63 applies an upward force to the limit rod 65, so that the limit rod 65 cooperates with the docking piece 66. The cooperation between the lock tongue of the door lock 4 and the lock seat 5 can limit the opening of the cabinet door 3, and the cooperation between the limit rod 65 and the docking piece 66 also limits the opening of the cabinet door 3. This realizes double-layer locking of the cabinet door 3. Even if a thief pries open the door lock 4, he cannot open the cabinet door 3, thereby greatly improving the anti-theft performance of the cabinet.

[0027] Furthermore, the pushing member 62 includes a wedge-shaped pressure block 621, which is fixedly connected to the end of the movable rod 61. A receiving groove 622 matching the wedge-shaped pressure block 621 is provided on the inner side of the lock seat 5. The wedge-shaped pressure block 621 slides in cooperation with the receiving groove 622. A return spring 623 is sleeved on the movable rod 61. One end of the return spring 623 abuts against the wedge-shaped pressure block 621, and the other end of the return spring 623 abuts against the inner wall of the receiving groove 622. When the door lock 4 is closed, the lock tongue abuts against the inclined surface of the wedge-shaped pressure block 621. The length of the wedge-shaped pressure block 621 is the same as the length of the lock tongue of the door lock 4. When the door lock 4 is closed, the lock tongue contacts the inclined surface of the wedge-shaped pressure block 621, which causes the wedge-shaped pressure block 621 to be squeezed and slide, thereby causing the movable rod 61 to slide. At this time, the return spring 623 is compressed and accumulates potential energy, which causes the connecting rod 63 to apply an upward force to the limit rod 65, thereby causing the limit rod 65 to cooperate with the docking piece 66, thereby limiting the opening of the cabinet door 3.

[0028] Furthermore, the docking member 66 includes a connecting plate 661 , one end of which is fixedly connected to the cabinet door 3 , and the other end of the connecting plate 661 is provided with a slot 662 , and the limiting rod 65 is slidably matched with the slot 662 .

[0029] Furthermore, an alarm 8 is provided on the top of the cabinet 2. The alarm 8 includes a protection box 81. The protection box 81 is fixedly connected to the top of the cabinet 2. An alarm 82 is fixedly connected to the inner side of the protection box 81. A plurality of sound amplification holes 83 are provided on the outer wall of the protection box 81. The plurality of sound amplification holes 83 are evenly distributed on the side wall of the protection box 81. A vibration sensor 7 is fixedly connected to the inner wall of the cabinet 2. A corresponding control panel is fixedly connected to the inner side of the cabinet 2. The cabinet 2 includes a processor. The vibration sensor 7 is connected to the processor signal. The output end of the processor is connected to the alarm 8. When the cabinet 2 is damaged by external force and vibrates, the vibration sensor 7 detects the vibration information and then sends a signal to the processor. After receiving the signal, the processor controls the alarm 82 to sound an alarm to deter thieves. The protection box 81 can prevent thieves from directly destroying the alarm 82.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
