Abstract

The invention discloses a locking device of an electric appliance. The locking device comprises a casing, the front side of the casing is provided with a work panel, the work panel is provided with grooves, each groove is internally provided with a jack, a plug is arranged outside the grooves, the top and the bottom of each groove are provided with infrared sensors respectively, the top and bottomof the work panel are provided with movable cardboards respectively, one end of each movable cardboard is provided with a first pressure bar, the inner side of the work panel is provided with a transitional connection board, and the transitional connection board is provided with through grooves. Power on / off is realized via memory alloy, the plug is clamped or loosened by utilizing the characteristic that the memory alloy expands with cold and contracts with heat, and the plug is plugged firmly and plugged in / out easily; and the infrared sensors send a signal to a PLC when it is detected thatthe distance to the hands is very near, the PLC controls the movable cardboards and a second pressure bar to work, the plug is connected with a socket and fastened, and electric shock caused by poweron by inserting the plug directly is avoided.

Description

technical field [0001] The invention relates to the field of bridge construction equipment, in particular to a locking device for electrical equipment. Background technique [0002] In the construction process of bridge construction, a large amount of electrical equipment that consumes electricity is needed. Since the plugs and sockets of existing electrical equipment are generally connected by friction fit, and no other locking devices are provided, when the staff pass by Or if other objects touch it, it is easy to knock the plug of the electrical equipment open, affecting the use of the electrical equipment. [0003] Therefore, it is necessary to invent a locking device for electrical equipment to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a locking device for electrical equipment, so as to solve the problems raised in the background art above. [0005] In order to achieve the above object, the present...
