The invention discloses a closing-opening device for a change-over switch electric appliance in a low-voltage cabinet. The closing-opening device includes a front baffle plate and two side baffle plates, wherein a drive board is attached to the outer surface of the front baffle plate; at least two limited pillars penetrate through the drive board and are arranged on the front baffle plate; vertical long bar-shaped holes corresponding to the limited pillars are formed in the drive board; a drive disc is hinged to the front baffle plate; an arc groove taking a linkage point as the center of circle is formed in the drive disc; a limiting spindle sleeve is arranged in the arc groove; the limiting spindle sleeve is hinged to the front baffle plate; one side, close to the drive board, on the drive disc is hinged to a drive pillar; a guide groove corresponding to the drive pillar is formed in the drive board; the drive pillar stretches into the guide groove to drive the drive board to move upand down; a stroke groove is formed in one side baffle plate; a poker rod is arranged in the stroke groove; the drive board is connected with a transmission mechanism; and the poker rod is driven bythe transmission mechanism, and then the poker rod moves to the other end from one end of the stroke groove to realize switching of the closing state and the opening state. The closing-opening devicefor a change-over switch electric appliance in a low-voltage cabinet has the advantages of simple structure, convenient assembling and low cost.
Description
technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a closing and opening device for a switch electric appliance in a low-voltage cabinet. Background technique [0002] The closing and opening device is an important component mechanism in the transfer switch in the low-voltage cabinet. The existing closing and opening device is usually composed of two independent mechanisms and the corresponding linkage mechanism and coil. The two independent mechanisms That is, the closing mechanism that is specially responsible for the closing of the automatic transfer switch and the opening mechanism that is specially responsible for the opening of the automatic transfer switch. When the closing coil in the closing mechanism is energized, the coil pulls in to drive the closing linkage mechanism. Closing operation; when the opening coil in the opening mechanism is energized, the coil pulls in and drives the opening linkage mec...
