Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defect 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 the operating axis, quadric chain and the output shaft that are located in frame, and described operating axis is connected with the input of quadric chain, and the output of described quadric chain is connected with output shaft; Described locking and releasing device comprise swing arm, the first rotating shaft and the pendulum plate and the cam that are used in conjunction with; The middle part of described swing arm is rotatably connected in frame; One end of described swing arm is hinged on output shaft, and the other end of described swing arm is provided with arc piece; The first described rotating shaft is rotatably connected in frame; The outer end of the first described rotating shaft is provided with an operating grip, and the inner disc of described the first rotating shaft is provided with a stopper slot matching with arc piece; Described pendulum plate middle part is fixed in the second rotating shaft; Described cam is arranged on operating axis; One end of described pendulum plate be located at cam directly over.
The middle part of described swing arm is rotatably connected in frame and refers to: in described frame, be rotatably connected to the second rotating shaft, the second described rotating shaft and the middle part of swing arm are rotationally connected.
The other end of described pendulum plate be located at the second rotating shaft under.
In described frame, be also provided with one for limiting the limit shaft of swing arm position, described swing arm is provided with the deep-slotted chip breaker coordinating with limit shaft, and described limit shaft can be against in deep-slotted chip breaker.
Described limit shaft is located at the described other end near the swing arm of arc piece.
Adopt after 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 against the force of the spring acting, but utilize cam and output shaft to drive whole locking and releasing device action, in the time discharging, only need to gently rotate the first rotating shaft with have gentle hands, therefore spring operating mechanism of the present invention operates very simple.In addition, due to contactless between arc piece and stopper slot in the time discharging, therefore also just do not have the problem that causes locking and releasing device to lose efficacy due to wearing and tearing, therefore the functional reliability of spring operating mechanism of the present invention is higher.
