Abstract

A variable voltage controller with a protection function disclosed by the present invention comprises a controller, sliding grooves are formed in the left side and the right side of the lower part of the front surface of the controller, a protection mechanism comprises a square block, a first arc plate, a chute, a short plate, a transverse plate, a threaded rod and a handle, and the outer wall of the square block is slidably clamped with the left side of the inner wall of the sliding groove. And a first arc plate is arranged at the bottom of the square block. The protection mechanism controls the first arc plate to move and cooperate with the second arc plate to abut against and fix the wire, thereby preventing the connection part of the wire from being bent and worn, guaranteeing the normal use of the controller, preventing the connection part from being loosened due to the dead weight of the wire, solving the pulling problem, guaranteeing the stable connection and achieving the installation of the controller. The installation is convenient, the disassembly is easy, and the working difficulty is reduced. And meanwhile, bolt fixation is changed through the control mechanism and the clamping mechanism, the problem of rust is solved, disassembly of the controller is guaranteed, overall damage and disassembly are not needed, cost is saved, usability is improved, and popularization is convenient.

Description

technical field [0001] The invention relates to the technical field of variable voltage controllers with protection functions, in particular to a variable voltage controller with protection functions. Background technique [0002] The variable voltage controller refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order. [0003] The existing variable voltage controller cannot protect the connecting wire during use, and the connection is easy to bend and wear, resulting in damage to the wire and affecting the normal use of the controller. Moreover, the wire will pull on the connection due to its own weight, and it is easy to loosen for a long time. Affects the stability of the connection, and the controller is fixed with bolts, which is troublesome to install and inconvenient to disassem...
