Abstract

The invention discloses an electric appliance plate capable of being conveniently disassembled and assembled and an electric appliance box. One end of the electric appliance plate is provided with a bolt mounting hole, the other end of the electric appliance plate is provided with a bolt steering device, the bolt steering device comprises a fixing plate, a transverse bolt, a vertical bolt and a fastening nut, and a protruding section of the fixing plate comprises two vertical sections and a transverse section connected with the two vertical sections. The fixing plate is arranged on the electric appliance plate, the transverse bolt penetrates through the two vertical sections, the fastening nut is arranged on the electric appliance plate, the vertical bolt sequentially penetrates through the electric appliance plate, the fastening nut and the transverse section, the vertical bolt is in threaded fit with the fastening nut, the transverse bolt is provided with a driving bevel gear, and the vertical bolt is provided with a driven bevel gear capable of being meshed with the driving bevel gear. The electric appliance box comprises the electric appliance plate, the electric appliance plate is arranged on the inner top wall of the electric appliance box, and the bolt mounting holes are close to the maintenance surface of the electric appliance box. According to the invention, the fastening direction of the bolts is converted from the vertical direction to the horizontal direction through the bolt steering device, so that loosening and locking of the rear-row bolts are easily realized, and single-side dismounting and maintenance of the electric appliance plate are realized.

Description

technical field [0001] The invention relates to electrical equipment, in particular to a conveniently disassembled and assembled electrical panel and electrical box. Background technique [0002] The components in the electrical box on the urban rail are usually installed on the electrical board, and the electrical board is fixed on the box body by two rows of bolts at the front and back. If the components on the electrical board are damaged, because it involves removing the wires and removing the front and rear bolts, then remove the electrical board and replace the components. Due to the complicated operation, the front and rear doors of the electrical cabinet need to be opened for operation, but the space on the vehicle is limited, so it is usually necessary to disassemble the entire electrical box for maintenance and replacement in such cases. This operation is time-consuming and laborious, and also delays the operation of urban rail vehicles. Contents of the inventio...
