Description
Technical Field
The utility model relates to a low-voltage apparatus technical field, in particular to circuit breaker energy storage buffer gear.
Background
The operating mechanisms of most circuit breakers at present are mechanical. If the circuit breaker is broken, the energy must first be stored in the operating mechanism of the circuit breaker by means of a compression spring for closing to be done without any human effort. At present, a few manufacturers have own operating mechanisms, and particularly, the operating mechanisms of the manufacturers in China are different. This results in the homogenization of the domestic circuit breaker product. For spring compression mechanisms, energy losses during compression and release of the spring are minimized. In order to stably and reliably switch on and off the circuit breaker, the capacity of an energy storage spring must have design allowance, excessive energy release can cause the cam of the energy storage mechanism to overshoot, and therefore the risk of false switching-on is brought.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a circuit breaker energy storage buffer gear, it is through setting up a buffer gear who comprises the leaf spring on the curb plate, cushions the backstop to the cam of energy storage, absorbs unnecessary energy.
In order to achieve the above object, the utility model provides a pair of circuit breaker energy storage buffer gear includes:
the spring piece is arranged on the side surface of the side plate opposite to the energy storage cam, one end of the spring piece is fixed with the side plate, and the other end of the spring piece can freely extend; the spring piece is provided with an arched area in the middle, and the arched area is set to be in a way that when an energy storage system releases energy to enable the energy storage cam to rotate, the energy storage cam is in contact with the arched area to press the arched area, so that the energy storage cam is stopped and the rotation of the energy storage cam is buffered; and when the energy storage system stores energy to enable the energy storage cam to rotate, the energy storage cam is not in contact with the arched area.
Furthermore, one end of the spring piece is provided with a fixing hole which is fixed with the side plate through a mounting nail.
Further, the other end of the spring piece is provided with an extension hole which is a waist hole, the positioning nail is positioned in the extension hole and fixed on the side plate, and when the arched area is extruded by the energy storage cam to extend, the other end of the spring piece can move relative to the positioning nail.
Further, the energy storage cam comprises a cantilever, when the energy storage system releases energy to enable the energy storage cam to rotate, the cantilever of the energy storage cam is in contact with the arched area to press the arched area, and therefore stopping and buffering of rotation of the energy storage cam are achieved; and when the energy storage system stores energy to enable the energy storage cam to rotate, the cantilever is in contact with the arched area.
The utility model provides a pair of circuit breaker energy storage buffer gear, the inventor considers the energy storage of energy storage cam and the rotatory characteristics of release energy, and the simple structure of make full use of leaf spring, simple to operate's performance receives the extrusion compression through it and cushions the backstop in order to absorb unnecessary energy to the cam, simple structure, good reliability, and the mechanical life who uses is high.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1, 2 and 4, the utility model provides a pair of circuit breaker energy storage buffer gear is used on the curb plate 6 of general circuit breaker 1 energy storage mechanism, can interact with energy storage cam 2.
Referring to fig. 3 to 8, the utility model provides a pair of circuit breaker energy storage buffer gear includes a spring leaf 3 that sets up on the relative energy storage cam 2's of curb plate 6 side, and 3 one end of spring leaf is equipped with fixed orifices 9, and it is fixed with curb plate 6 through installation nail 4, and the other end of spring leaf 3 is equipped with extension hole 8, and extension hole 8 sets to a waist hole (see fig. 6), and location nail 5 is located in extension hole 8 and fixing on curb plate 6, the size in extension hole 8 is greater than the diameter of location nail 5, and like this, spring leaf 3 can remove for location nail 5 for this tip can freely extend. The spring plate 3 is provided with an arched area 10 in the middle, and the arched area 10 protrudes towards the energy storage cam 2.
