specific Embodiment 1

[0048] The structure of the spring operating mechanism is as follows Figure 1 to Figure 3 As shown, the spring operating mechanism in this embodiment includes a frame body 9 on which a power shaft 10 and an energy storage shaft 11 are rotatably mounted. The transmission mechanism drives the energy storage shaft 11 to rotate in the forward direction. An energy storage spring is arranged on the frame body 9. The energy storage spring is connected to the crank arm transmission on the energy storage shaft 11. When the energy storage shaft 11 is rotating forward, it can force The energy storage spring is deformed to realize the energy storage operation.

[0049] The power shaft 10 is provided with a driven sprocket, and the frame body 9 is provided with a motor, which drives the driving sprocket to rotate, and the driving sprocket drives the driven sprocket 13 to rotate through the chain, thereby driving the power shaft 10 to rotate forward.

[0050] The power shaft 10 drives the...

specific Embodiment 2

[0063] It differs from Embodiment 1 mainly in that: in Embodiment 1, the pawl plate is rotatably assembled on the energy storage shaft. In this embodiment, the pawl plate is rotatably assembled on the frame body, and special support bearings can be provided to realize the rotation of the pawl plate. Of course, at this time, the pawl plate should still be arranged coaxially with the energy storage shaft.

specific Embodiment 3

[0065] The difference between it and Embodiment 1 mainly lies in that in Embodiment 1, the pusher adopts a roller, which contacts and pushes with the driving cam wire. In this embodiment, the push member can adopt a circular shaft to push and cooperate with the drive cam, and can also drive the ratchet plate to swing forward.

Abstract

The invention relates to a spring operating mechanism. The spring operating mechanism comprises a frame; a power shaft, an energy storage shaft, an energy storage transmission mechanism and an energy storage spring are assembled on the frame; the energy storage transmission mechanism comprises a ratchet wheel, a pawl plate, a driving pawl, a pushing piece and a driving cam; when the power shaft rotates forwards to input energy storage driving force, the driving cam follows theforward rotation of the power shaft, the pawl plate is forced to swing forwards through the pushing piece, and the driving pawl drives the ratchet wheel to drive the energy storage shaft to rotate forwards by a set angle; and the power shaft continuously rotates to drive the energy storage shaft to continuously rotate forwards until the energy storage operation is completed. The energy storage transmission structure is simple in structure and convenient to machine, manufacture and assemble. Moreover, as the pawl plate and the energy storage shaft are coaxially arranged, the radial size of the pawl plate can be designed according to actual needs, and therefore, the space utilization rate is improved, intensive management of products is realized, and the miniaturization design of the spring operating mechanism is facilitated.

Description

technical field [0001] The invention belongs to the technical field of operating mechanisms of electric switches, and in particular relates to a spring operating mechanism. Background technique [0002] Most of the energy storage devices of the existing spring operating mechanism adopt a motor to directly drive the pawl shaft, and the two large and small pawls on the pawl shaft drive the ratchet to rotate, so as to realize energy storage of the mechanism. This energy storage method leads to a larger space occupied by the energy storage device of the operating mechanism, which is not conducive to reducing the volume of the overall spring operating mechanism, thereby realizing the design characteristics of miniaturization and intensification of the operating mechanism. [0003] An energy storage structure of a spring operating mechanism is disclosed in the Chinese utility model patent specification whose authorized announcement number is CN2341258Y, which includes a ratchet co...
