Multi-station ratchet switch

Abstract

The invention discloses a multi-station ratchet switch. The switch comprises a control transposition part and three switch contact parts. The control transposition part is composed of a fixed base, arotary base, a pair of inner meshing gears, a gear shaft and a motor. An output shaft of the motor is fixedly connected with the gear shaft. The pinion is fixedly arranged on the gear shaft. The gearwheel is fixedly mounted on the rotary base. When the motor drives the pinion to rotate, the rotary base is driven by the gearwheel to rotate along with the gearwheel, implementing transposition. The three contact parts are uniformly and fixedly mounted on the rotary base. The contact part controls the opening and closing actions of a switch through a ratchet wheel, a cam and a pair of bevel gears.The ratchet wheel motor drives the ratchet wheel to periodically rotate by 90 degrees. Two contact blocks placed at 180 degrees are fixedly installed on the ratchet wheel, the cam placed on the horizontal bevel gear controls the baffle to do reciprocating motion on the bevel gear shaft, the ratchet wheel makes contact with and is opened from the contact blocks on the baffle, and the switch has the advantages of being capable of adapting to various working environments, high in safety coefficient and convenient to operate.

Description

technical field [0001] The invention relates to the electrical field, in particular to a multi-position ratchet switch. Background technique [0002] With the development of all walks of life and the dependence on electric energy, electric energy has begun to be applied to various environments and working conditions. Each situation has different requirements for switches. At this time, a switch that can adapt to multiple A working condition of the switch to solve this problem. For example, in the prior art (201721304921.2), a multi-position switch for quenching is disclosed, which includes a mounting base, an output female electrode disposed on the mounting base, and at least two input electrodes disposed on the mounting base, and each Each input electrode is correspondingly provided with a switching assembly; one end of the switching assembly is connected to the mounting base, and the other end is provided with an electrode switching board that can move up and down. And l...

For example, in the prior art (201721304921.2), a multi-position switch for quenching is disclosed, which includes a mounting base, an output female electrode disposed on the mounting base, and at least two input electrodes disposed on the mounting base, and each Each input electrode is correspondingly provided with a switching assembly; one end of the switching assembly is connected to the mounting base, and the other end is provided with an electrode switching board that can move up and down. And leave the outgoing and incoming electrodes to conduct or disconnect the electric circuit. This invention is only used in the quenching process and has relatively large limitations. Therefore, the present invention provides a multi-position ratchet switch
