Description

Technical Field

[0001] The utility model belongs to the technical field of controllers, and particularly relates to an anti-disassembly structure for a controller shell. Background Art

[0002] A controller refers to a master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit in accordance with a predetermined sequence to control the starting, speed regulation, braking, and reverse of a motor. It mainly consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. During the use of the controller, in order to prevent someone from privately disassembling the controller, an anti-disassembly structure is usually installed on the shell of the controller, and an alarm is triggered when the anti-disassembly structure is used by the user to privately disassemble the controller.

[0003] A document with the publication number of CN111741637B discloses an anti-disassembly structure for a vehicle scale controller shell, which includes a lower shell and an upper shell. The lower shell and the upper shell are connected by connecting bolts. A trigger switch is arranged on the lower shell, a guide sleeve is arranged on the lower shell, a resisting rod is connected in the guide sleeve, one end of the resisting rod abuts against the trigger switch, and the other end abuts against the upper shell.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. For the anti-disassembly structure of the controller shell mentioned above, a trigger switch is arranged on the lower shell, and a resisting rod is connected to the lower shell through a guide sleeve. The two ends of the resisting rod respectively abut against the trigger switch and the upper shell. Since the length of the resisting rod is fixed, the resisting rod can only be used for the lower shell and the upper shell with a specific distance, and it is not convenient to be used for the lower shell and the upper shell with different distances for anti-disassembly protection.

[0006] 2. For the anti-disassembly structure of the controller shell mentioned above, one end of the guide sleeve is installed on the lower shell through a fixed bracket, the other end of the guide sleeve is installed on the upper shell through a screw and a first rod body, and the resisting rod is installed through the guide sleeve. It is not convenient to install and disassemble the guide sleeve between the lower shell and the upper shell, and it is not convenient to install and disassemble the anti-disassembly structure.
