The utility model relates to a novel, simple structure, the part technological requirement is reasonable, and the action reliability is very good, and the circuit breaker that causes of having avoided can not reseing at once or can not reseing because of the energy -stored spring traditionally damages, has reduced the unnecessary loss from this.
Description
Technical field
The present invention relates to a kind of breaker mechanism servicing unit, specifically a kind of breaker mechanism switch-on latching device, belongs to technical field of electric equipment.
Background technology
Circuit breaker it not only can cut off or no-load current in closed high circuit and load current; and when system jam by the effect of relay protection; cut off overload electric current and short circuit current; it has quite perfect arc extinguishing structure and enough cutout abilities, can be divided into: oil circuit breaker (bulk-oil circuit-breaker, oil-minimum breaker), sulfur hexafluoride breaker (SF6 circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.
In circuit breaker operation mechanism, generally all need manually spring-compressed to be carried out energy storage, then locked by locking mechanism; When needs close a floodgate time; the effect of the acquisition rapid closing of the energy stored by Compress Spring is discharged at once by operational lock mechanism; traditionally because the locking mechanism of energy-stored spring arranges unreasonable; when not resetting at once after spring release; the poor reliability of action; the situation that circuit breaker therefore usually can be caused to damage occurs, and causes unnecessary loss thus.
How to provide one to arrange rational energy-stored spring locking mechanism, can not reset at once after solving spring release, the reliability improving action needs the problem of solution badly.
Utility model content
The utility model, in order to overcome the defect of prior art, discloses a kind of breaker mechanism switch-on latching device.
An object of the present utility model is, provides a kind of breaker mechanism switch-on latching device of rational in infrastructure, reliable in action.
In order to realize according to these objects of the present utility model and other advantage, provide a kind of breaker mechanism switch-on latching device, comprise torsion spring, there is the connecting lever axle rotating trend to closing position under torsion spring effect, connecting lever axle is provided with connecting lever, connecting lever is provided with roller, the side of connecting lever is provided with the sincere sub-axle of the maintenance be arranged on pedestal, keep sincere sub-axle being provided with the energy storage can rotated around sincere sub-axle and keep sincere son, energy storage keeps being provided with torsion spring between sincere son and sincere sub-axle, the elastic force of torsion spring can make energy storage keep sincere son to turn to latched position, described energy storage keep the front end of sincere son have a spacing end face and can latched position make spacing end face be blocked in roller on the stroke of closing position movement, it is characterized in that, little centre, described connecting lever two is wide, its segment thickness be connected with connecting lever axle is greater than its part be connected with roller.
Preferably, described pedestal is provided with the pin that can limit energy storage and keep sincere sub-latched position.
Preferably, between described connecting lever and connecting lever axle, needle bearing is housed.
Preferably, described energy storage keeps the confined planes of sincere sub-end to be curved surfaces.
The utility model at least comprises following beneficial effect: adopt above-mentioned locker structure, it is novel in design, structure is simple, part process requires rationally, Reliability of Microprocessor is very good, avoid traditionally because the circuit breaker that energy-stored spring can not reset at once or can not reset and cause damages, thereby reduce unnecessary loss; According to the strength demand of connecting lever different parts, select different material thickness and shape, not only save material, improve connecting lever intensity, and connecting lever not easy fracture.
Part is embodied by explanation below by other advantage of the present utility model, target and feature, part also will by research and practice of the present utility model by those skilled in the art is understood.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model breaker mechanism switch-on latching device;
Fig. 2 is the side-looking structural representation of the utility model breaker mechanism switch-on latching device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
Fig. 1 and 2 shows according to a kind of way of realization of the present utility model, comprising torsion spring 4, there is the connecting lever axle 1 rotating trend to closing position under torsion spring 4 acts on, connecting lever axle 1 is provided with connecting lever 7, connecting lever 7 is provided with roller 6, the side of connecting lever 7 is provided with the sincere sub-axle 2 of the maintenance be arranged on pedestal, keep sincere sub-axle 2 being provided with the energy storage can rotated around sincere sub-axle 2 and keep sincere sub 5, energy storage keeps being provided with torsion spring 4 between sincere sub 5 and sincere sub-axle 2, the elastic force of torsion spring 4 can make energy storage keep sincere sub 5 to turn to latched position, described energy storage keep the sincere front end of sub 5 to have a spacing end face and can latched position make spacing end face be blocked in roller 6 on the stroke of closing position movement, little centre, described connecting lever 7 two is wide, its segment thickness be connected with connecting lever axle 1 is greater than its part be connected with roller 6.
Described pedestal is provided with the pin 3 that can limit energy storage and keep sincere sub 5 latched positions.
Between described connecting lever 7 and connecting lever axle 1, needle bearing is housed.
Described energy storage keeps the confined planes of sincere sub 5 ends to be curved surfaces.
As mentioned above, according to the utility model, keep on sincere sub-axle because combined floodgate energy storage keeps sincere son to adopt needle bearing to be enclosed within, can ensure that sincere son rotates flexibly; Because energy storage keeps sincere son installs torsion spring, energy storage can be made to keep sincere son to remain at pin institute restriction site, sell to adopt with mechanism mounting panel and be threaded, positioning precision is accurate; Because roller energy storage of being closed a floodgate keeps sincere sub-arc surface snap close, snap close contact zone is large, can ensure enough part strength and Mechanical Reliability; Due to the strength demand according to connecting lever different parts, select different material thickness and shape, not only save material, improve connecting lever intensity, and connecting lever not easy fracture.
Operation principle of the present utility model: in making process, connecting lever rotates clockwise the sincere sub-arc surface snap close of energy storage maintenance until connecting lever upper roller is closed a floodgate under switching force drives, and makes circuit breaker remain on "on" position; Combined floodgate energy storage keeps sincere son to rotate counterclockwise while obtaining switching signal, and the roller on connecting lever can roll across combined floodgate energy storage and keep sincere sub-arc surface, thus removes switch-on latching.Although embodiment of the present utility model is open as above, it is not restricted to listed in specification and execution mode utilization.It can be applied to various applicable field of the present utility model completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
