Abstract
The invention relates to the field of switch actuators, and particularly relates to a spring actuator with a flexible manual switching-on/off function. The spring actuator comprises a shell. A manual operation device and a rotation half shaft are arranged on the shell. The manual operation device includes an operation shaft assembled on the shell in a rotatable manner and a plunger assembly connected between the operation shaft and the rotation half shaft in a transmission mode. The operation shaft is provided with an operation shaft crank arm, and the rotation half shaft is provided with a half shaft crank arm. The plunger assembly includes a base, two force transfer members arranged on the base, and a buffer spring installed between the two force transfer members in an abutting mode. One of the two force transfer members is matched with the operation shaft crank arm, and the other is matched with the half shaft crank arm. During manual operation, even if a user uses too much strength, movement of the components can be buffered by the buffer spring, and strong impact and damage caused thereby are avoided. Therefore, the risk of damage of the spring actuator is reduced, and the reliability of the spring actuator is improved.

Embodiment
With the embodiment of the spring operating mechanism of flexible manual divide-shut brake function, as Figure 1-5, should comprise housing with the spring operating mechanism of flexible manual divide-shut brake function, housing is provided with hand-operating device and rotates semiaxis.
Housing comprises front plate 11 and rear plate 12, is fixed together between forward and backward clamping plate, and the structure of housing is prior art, is therefore no longer described in detail with regard to the structure of housing herein.
Hand-operating device comprises operating axis 13 and push rod component.
Operating axis 13 rotates and is assemblied on housing, before it is specifically assemblied in housing, on rear plate, it is fixedly equipped with operating axis connecting lever 14, operating axis connecting lever 14 is used for exporting the motion of operating axis 13, in the present embodiment, in order to limit the rotation amplitude of operating axis 13, it is also provided with and turns width connecting lever 15, turn width connecting lever 15 to be specifically made up of the bearing pin be fixed on operating axis, in order to turn width connecting lever 15 and coordinate, housing is also respectively equipped with at the both sides place turning width connecting lever and turns width locating part 16, in the present embodiment, turn width locating part 16 to be specifically made up of the backing pin be located on housing.
Push rod component comprises pedestal 17 and is located at pedestal 17 linearly can be contained in the buffer spring 18 between two force transmission elements in two force transmission elements of relative motion and top, in the present embodiment, pedestal 17 is specifically made up of the pilum be located on housing, one in two force transmission elements is power transmission cover 19, another for one end be plugged in power transmission cover 19 in transmission rod 20, wherein buffer spring 18 top be contained in transmission rod 20 the inner (insert power transmission cover in one end) and power transmission overlap between 19.Power transmission cover 19 is mobilizable to be vertically assemblied on pilum and near operating axis connecting lever 14 compared with transmission rod 20, the activity that operating axis connecting lever 14 can overlap 19 for power transmission provides top pressure power, in order to realize automatically reseting of power transmission cover 19, in the present embodiment, pedestal and power transmission are top-loaded with back-moving spring 21 between overlapping, power transmission cover 19 is coordinated with back-moving spring 21 by a baffle ring 22 set by it on, and baffle ring 22 is enclosed within power transmission and puts and overlap 19 anticreeps by a split pin 23 and power transmission and coordinate.
Rotate semiaxis 24 parallel to each other with operating axis 13, which is provided with semiaxis connecting lever 25, semiaxis connecting lever 25 is also for coordinating with push rod component, thus constitute the arrangement form of push rod component between operating axis connecting lever 14 and semiaxis connecting lever 25, the motion of operating axis connecting lever 14 passes to semiaxis connecting lever 25 by push rod component, semiaxis connecting lever 25 also can pass motion to operating axis connecting lever 14, in order to realize rotating automatically reseting of semiaxis 24, rotating semiaxis 24 and being provided with torsion spring 26; In order to limit the scope of activities of semiaxis connecting lever 25, the side place of the close push rod component at semiaxis connecting lever 25 on housing is provided with reset stop 27, limiting block stop member 28 is provided with at the side place deviating from reset stop of semiaxis connecting lever, reset stop 27 is adjustable stopper stop member, reset stop 27 specifically comprises the pillar be located on housing and the adjusting bolt be assemblied on pillar, threaded engagement between adjusting bolt and pillar, can realize the adjustment to semiaxis connecting lever institute extreme position by the position adjusting bolt, adjusting bolt is provided with locking nut and pad.
When using this spring actuator with flexible manual divide-shut brake function, can first rotating operation axle, operating axis is by the power transmission cover of operating axis connecting lever pushing push rod component, power transmission cover on the one hand compression reseting spring advances, transmission rod is pushed on the one hand by buffer spring, transmission rod and then push semiaxis connecting lever, semiaxis connecting lever orders about and rotates semiaxis rotation, thus the snapping end of deflecting cam plate 29 can be made to depart from the groove 30 rotated on semiaxis, and then unlock deflecting cam assembly 31, realize point (conjunction) lock of switch.In this process, the width connecting lever that turns of operating axis touches when turning width locating part and cannot rotate again in rotation process, even if operating axis is under external force continues increase effect, the power of push rod component transmission will remain on a constant value.Thus realize protection mechanism push rod component, semiaxis connecting lever and these delicate structure of limiting block stop member, the structural member that intensity is relatively limited, greatly improve the reliability of mechanism self.
In other embodiment of the spring operating mechanism with flexible manual divide-shut brake function, push rod component two force transmission elements also can also be all coordinate with foot guide, need not have direct assembly relation therebetween.
