Abstract

The invention relates to a bistable bidirectional self-locking device. The swing cam is fixedly installed on the connecting shaft, and the left and right sides of the swing cam are respectively provided with guide cylinders; the fixed base is arranged under the swing cam, and two freely rotatable spring brackets are installed on the left and right sides of the fixed base. hole; the spring bracket on the left side of the fixed base is connected with the guide cylinders on both sides of the swing cam respectively through the spring assembly; The U-shaped groove on the top is embedded in the guide cylinders on both sides of the swing cam and can rotate relatively. The guide spring and the energy storage spring are set on the guide rod together, and the guide spring is placed in the energy storage spring. The guide spring and the energy storage spring are The compressed state is installed between the groove seat and the spring bracket. The invention can realize a stable self-locking function when the swing mechanism swings in both directions, has simple structure, convenient assembly, flexible operation and is suitable for mass production.

Description

technical field [0001] The invention relates to a bidirectional self-locking swing mechanism applied to a circuit breaker, in particular to a bistable bidirectional self-locking device. Background technique [0002] With the continuous development of the circuit breaker industry, the two-way swing mechanism on the circuit breaker is more and more widely used. In order to realize the two-way self-locking of the swing mechanism, a self-locking structure is needed, but the traditional self-locking structure is complicated, and it is difficult to achieve two-way Self-locking has been unable to meet the requirements of miniaturization. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a bistable bidirectional self-locking device, which can realize a stable self-locking function when the swing mechanism swings in both directions, and has the advantages of simple structure, convenient assembly, fle...
