Technical field
The utility model belongs to technical field of electrical equipment, the energy-stored spring behaviour of more particularly to a kind of low voltage isolation switch Make mechanism.
Background technology
Need to cut off the electricity supply when electric equipment is repaired, maintenance part is isolated with live part, and keep effective isolation Distance, is at this moment accomplished by using low voltage isolation switch.Conventional low voltage isolation switch mainly includes housing, switch contact machine at present Structure, contacts cover, manually operated axle and handle;Wherein switch contact mechanism is located at the inside of housing;Contacts cover is arranged on switch Switch contact actuator on the upper end of contact mechanism, and switch contact mechanism runs through in a movable manner is arranged on contacts cover On perforate in;The bottom of manually operated axle is connected with an action bars, the outer end of action bars and opening on the outside of contacts cover Close contact actuator upper end side to be in contact, the upper end of manually operated axle extends to hull outside;Handle is then connected to manual behaviour Make the outer end of axle.When staff move handle and low voltage isolation switch is carried out point, closing operation when, in the drive of handle Under, manually operated axle will produce rotation, so as to drive action bars accordingly to rotate, then switch contact actuator touches driving switch Head mechanism on contact and make its separate or close.But, there is following point in this low voltage isolation switch:The closure of contact Speed is relevant with the service speed of staff, i.e., so-called relevant manual operation, once service speed is excessively slow, disconnecting switch is just It is easy to burn.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of energy-stored spring operation machine of low voltage isolation switch Structure, by the design of stroke compensating unit, ensure that the action of low voltage isolation switch is unrelated with manual operation.
Therefore, the technical solution of the utility model is:
The energy-stored spring operating mechanism of a kind of low voltage isolation switch, installed in the top of low voltage isolation switch, including operation Axle, driving lever and stroke compensating unit;
The bottom of the operating shaft is arranged on the top of the low voltage isolation switch, radially can freely rotate;
The driving lever has two, the orthogonal and fixed bottom for being arranged on the operating shaft;
The stroke compensating unit includes spring installation axle spring, rotating shaft, galianconism, long-armed, first axle, the second axle and cylinder Shape is raised;The spring installation axle is hinged in the operating shaft, on the upside of the driving lever;The freedom of the spring installation axle End sets the first long strip through hole;The spring is through in the spring installation axle;The rotating shaft is arranged on the low voltage isolation switch Top, radially can freely rotate;The galianconism, it is long-armed be respectively and vertically fixed in the rotating shaft, both are parallel to each other; The bottom of the first axle be fixed on it is described it is long-armed on, its top is fixed on the free end of the galianconism;The first axle is passed through The first long strip through hole set in the spring installation axle;The long-armed free end is provided with the second long strip through hole, described second Axle can be under the promotion of the driving lever along second long strip through hole slip;The long-armed bottom, which is fixed, is formed with circular cylindrical projection Rise.
Specifically, the bottom of second axle is formed with chassis or fixture block;Shape on the second long strip through hole inwall The groove that chassis described in Cheng Youyu or fixture block match;Chassis or fixture block are slided along groove.
Or following connected mode can also be changed into:The second axle bottom sets groove, the inside of second long strip through hole Provided with track, groove slides along the track.
The energy-stored spring operating mechanism of the low voltage isolation switch be using the idle stroke in spring installation axle and rotary shaft come Ensure that the operation speed of operating personnel is unrelated with the action switched, thus contact can be made quickly to divide, close, it is to avoid to keep apart Close contact burnout failure.In addition, also having reasonable in design, simple, cost low, without entering to former low voltage isolation switch structure The advantages of row is changed.

The working state figure of the energy-stored spring operating mechanism for the low voltage isolation switch that Fig. 2 provides for the utility model.
Embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the energy-stored spring operating mechanism of a kind of low voltage isolation switch, installed in the top of low voltage isolation switch Portion, including operating shaft 1, driving lever 2 and stroke compensating unit 3;
The bottom of operating shaft 1 is arranged on the top of low voltage isolation switch, radially can freely rotate;
Driving lever 2 has two, the orthogonal and fixed bottom for being arranged on operating shaft 1;
Stroke compensating unit 3 includes spring installation axle 301, spring 302, rotating shaft 303, galianconism 304, long-armed 305, first axle 306th, the second axle 307 and cylindrical protrusions 308;Spring installation axle 301 is hinged in operating shaft 1, positioned at the upside of driving lever 2;Spring The free end of installation axle 301 sets the first long strip through hole 309;Spring 302 is through in spring installation axle 301;Rotating shaft 303 is arranged on low The top of disconnecting switch is pressed, radially can freely be rotated;Galianconism 304, long-armed 305 are respectively and vertically fixed in rotating shaft 303, and two Person is parallel to each other;The bottom of first axle 306 is fixed on long-armed 305, and its top is fixed on the free end of galianconism 304;First axle 306 pass through the first long strip through hole 309 set in spring installation axle 301;Long-armed 305 free end is provided with the second long strip through hole 310, the second axle 307 can be slided along the second long strip through hole 310 under the promotion of driving lever 2;Long-armed 305 bottom is fixed and is formed with circle Column-shaped projection 308.
Specifically, the bottom of the second axle 307 is formed with chassis or fixture block;Formed on the inwall of second long strip through hole 310 There is the groove matched with chassis or fixture block;Chassis or fixture block are slided along groove.
Or following connected mode can also be changed into:The bottom of second axle 307 sets groove, and the inside of the second long strip through hole 310 is set There is track, groove slides along the track.
