Abstract

The invention provides a fast on-off switch. The fast on-off switch comprises a bottom plate, a pin A, an air cylinder, a swing rod, a pin B, a cylinder barrel, a gear, a pin C, a cylindrical rod, a compression spring, a vertical plate, an L-shaped support and the like and is characterized in that the cylinder barrel is horizontally leftwards mounted on the bottom plate, the cylinder barrel is provided with a natural gas inlet and an air inlet in the upper portion, the right side of the cylinder barrel is sealed, the right end face of the cylinder barrel is provided with a circular hole, a spark plug is mounted in the circular hole, and an exhaust valve is arranged on the front side of the cylinder barrel. The fast on-off switch has the advantages that the rack can be pushed to move by the fast expansion of fuel gas by the aid of the air cylinder and the spark plug, the rack drives the gear and the L-shaped support to fast rotate clockwise, the off pressure between two copper contacts is large, and high off speed is achieved.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a quick on-off switch. Background technique [0002] At present, some low-voltage switches on the market have a slow closing speed, are prone to arcing, and the contact pressure between the contacts is not large enough, so there is an urgent need for a switch with a fast closing speed and high contact pressure. Contents of the invention [0003] In view of the above problems, the present invention provides a quick on-off switch. By setting the cylinder and the piston, the present invention can use the rapid expansion of the gas to push the rack to move. The rack drives the gear and the L-shaped bracket to rotate clockwise quickly. The two copper The closing pressure between the contacts is large and the closing speed is fast. [0004] The technical solution used in the present invention is: a quick on-off switch, including a base plate, a pin A, a cylinder, a swing rod,...
