Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a controller fixing structure. Background Art

[0002] A controller refers to a main command device that controls the starting, speed regulation, braking and reversal of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit in a predetermined order. The controller consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the decision-making body that issues commands, that is, it completes the coordination and command of the operation of the entire computer system. The controller is divided into combinational logic controllers and microprogram controllers. The two controllers have their own strengths and weaknesses. The combinational logic controller is difficult to design and has a complex structure. Once the design is completed, it cannot be modified or expanded, but it is fast. The microprogram controller is easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram.

[0003] After searching, the patent document with publication (announcement) number: CN220674260U discloses a controller fixing structure and a controller, including a fixed base, and the upper outer surface of the fixed base is detachably connected to a protective shell. When using this device, the ventilation performance of the bottom of the protective shell can be increased by the provided ventilation filter, and the moisture at the bottom of the device can be absorbed by the provided moisture-absorbing gasket to prevent the device from being eroded by moisture and affecting normal use. The force generated when the device is shaken is reduced under the cooperation of the telescopic round rod and the shock-absorbing spring, thereby extending the service life of the device. The speed at which the device dissipates heat is accelerated under the action of the limit groove and the ventilation fan, effectively extending the service life of the device. The fixed baffle is fixed to the surface of the box or wall under the action of the supporting column and the connecting baffle, and the protective shell is sleeved on the side of the fixed baffle through the limit slide groove and fixed with a limit screw. The structure is simple and easy to disassemble and assemble, which can bring better usage prospects.

[0004] However, it is inconvenient to remove the controller from the protective shell during use of the device. Therefore, we propose a controller fixing structure to solve the above problem. Utility Model Content
