Technical field
The present invention relates to electrical equipment technical field, specifically is a kind of spring operating mechanism.
Background technology
The spring operating mechanism of prior art comprises frame and rack-mounted operating means and locking and releasing device; Described operating means is made up of operating axis, quadric chain and output shaft; Described operating axis is connected with the input of quadric chain, and the output of said quadric chain is connected with output shaft; Described locking and releasing device by a back-moving spring, slide block and one and the swing arm that offsets of slide block form, described output shaft is connected with swing arm.Swing arm props up the slide block action when swing, drive the back-moving spring acting simultaneously, and when arriving certain position, slide block is taken back by back-moving spring and resetted, and locks.During release, pull at the movable slider action, overcome back-moving spring and do manual work, when arriving certain position, slide block leaves with swing arm mutually, and swing arm resets.There is following defective in the spring operating mechanism of said structure in the use of reality: because the locking of this kind structure and releasing device in use all need the acting of customer service spring resistance, the comparison difficulty therefore operates.And when discharging, because swing arm has very strong resilience force, so slide block and swing arm be prone to frayed and cause locking and the inefficacy of releasing device, thereby the functional reliability of the spring operating mechanism of prior art is relatively poor.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the defective of above prior art, and a kind of simple to operate and spring operating mechanism that functional reliability is high is provided.
Technical scheme of the present invention is, a kind of spring operating mechanism is provided, and comprises frame and rack-mounted operating means and locking and releasing device; Described operating means comprises operating axis, quadric chain and the output shaft that is located on the frame, and described operating axis is connected with the input of quadric chain, and the output of said quadric chain is connected with output shaft; Described locking and releasing device comprise swing arm, first rotating shaft and the pendulum plate and the cam that are used; The middle part of said swing arm is rotatably connected on the frame; One end of said swing arm is hinged on the output shaft, and the other end of said swing arm is provided with the arc piece; Described first rotating shaft is rotatably connected on the frame; The outer end of described first rotating shaft is provided with an operating grip, and the disc of the inner of said second rotating shaft is provided with the stopper slot that matches with the arc piece; Described pendulum plate middle part is fixed in second rotating shaft; Described cam is installed on the operating axis; One end of said pendulum plate be located at cam directly over.
The middle part of said swing arm is rotatably connected on the frame and is meant: be rotatably connected to second rotating shaft on the described frame, the middle part of described second rotating shaft and swing arm is rotationally connected.
The other end of said pendulum plate be located at second rotating shaft under.
Also be provided with on the described frame one be used to limit the swing arm position limit shaft, described swing arm is provided with the deep-slotted chip breaker that cooperates with limit shaft, described limit shaft can be against in the deep-slotted chip breaker.
Described limit shaft is located at the end near the swing arm of arc piece.
After adopting above structure, the present invention compared with prior art has the following advantages:
The locking of spring operating mechanism of the present invention and releasing device all do not need the against the force of the spring acting; But utilize cam and output shaft to drive whole locking and releasing device action; When discharging, only need get final product, so spring operating mechanism of the present invention operates very simple with the light rotation of have gentle hands first rotating shaft.In addition because contactless between arc piece and the stopper slot when discharging, therefore also with regard to not existing because wearing and tearing cause locking and the problem of releasing device inefficacy, so the functional reliability of spring operating mechanism of the present invention is higher.
