Abstract
The invention discloses a breaker mechanism energy storage lock catch apparatus. The apparatus comprises a camshaft which is connected with an energy storage spring and has a trend of rotating towards a switching-on position under the effects of the energy storage spring. The camshaft is provided with a cam capable of driving a beaker mechanism to be switched on; the camshaft is provided with a connecting lever; the connecting lever is provided with a roller; the side of the connecting lever is provided with a pawl shaft installed on a base body; the pawl shaft is provided with a pawl capable of rotating about the pawl shaft; a torsion spring is arranged between the pawl and the pawl shaft; the spring force of the torsion spring can enable the pawl to rotate to a locking position; and the front end of the pawl is provided with a limiting end surface and can enable the limiting end surface to block in the roller' stroke of moving towards the switching-on position at the locking position. By using the foregoing structure, the design is novel, the structure is simple, the part technology requirements are reasonable, the motion reliability is quite good, the damage to a breaker caused by the incapability of immediate reset or incapability of reset of the energy spring is avoided, and accordingly unnecessary loss is reduced.
Description
?
Technical field
The present invention relates to a kind of breaker mechanism servicing unit, specifically a kind of breaker mechanism energy storage locker, belongs to electric equipment technical field.
Background technology
In circuit breaker operation mechanism, generally all need manually spring-compressed to be carried out to energy storage, then by locking mechanism, lock; When needs close a floodgate; by operational lock mechanism, discharge at once the effect of the acquisition rapid closing of the stored energy of Compress Spring; locking mechanism due to energy-stored spring arranges unreasonable traditionally; can not immediate replacement after spring discharges; the poor reliability of action; the situation that therefore usually can cause circuit breaker to damage occurs, and has caused thus unnecessary loss.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of breaker mechanism energy storage locker of rational in infrastructure, reliable in action.
In order to solve the problems of the technologies described above, breaker mechanism energy storage locker of the present invention, comprise and be connected with energy-stored spring and under the effect of energy-stored spring, have to the camshaft of closing position rotation trend, the cam that can drive breaker mechanism to close a floodgate is installed on camshaft, connecting lever is installed on camshaft, on connecting lever, be provided with roller, one side of connecting lever is provided with the sincere sub-axle being arranged on pedestal, on sincere sub-axle, be provided with the sincere son that can rotate around sincere sub-axle, between sincere son and sincere sub-axle, torsion spring is installed, the spring force of torsion spring can make sincere son turn to latched position, the front end of sincere son has a spacing end face and can spacing end face is blocked on the stroke moving to closing position of roller in latched position.
On described pedestal, be provided with the spacer pin that can limit sincere sub-latched position.
The confined planes of described sincere sub-end is arranged to curved surfaces.
Adopt after above-mentioned structure, due to the locker arranging, its modern design, simple in structure, part process requires rationally, Reliability of Microprocessor is very good, avoided traditionally because of energy-stored spring can not immediate replacement or the circuit breaker causing that can not reset damage, reduced thus unnecessary loss.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of breaker mechanism energy storage locker of the present invention;
Fig. 2 is the side-looking structural representation of breaker mechanism energy storage locker of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, breaker mechanism energy storage locker of the present invention is described in further detail.
As shown in the figure, breaker mechanism energy storage locker of the present invention, comprise and be connected with energy-stored spring and under the effect of energy-stored spring, have to the camshaft 1 of closing position rotation trend, the cam 7 that can drive breaker mechanism to close a floodgate is installed on camshaft 1, and cam adopts keyway to be connected with camshaft; On camshaft 1, connecting lever is installed, on connecting lever, be provided with roller 6, one side of connecting lever is provided with the sincere sub-axle 2 being arranged on pedestal, is provided with and can is enclosed within on sincere sub-axle and guarantees that sincere son rotation is flexible around sincere sub 5, sincere sub 5 preferential employing needle bearings of sincere sub-axle 2 rotations on sincere sub-axle 2; Sincere sub 5 and sincere sub-axle 2 between torsion spring 4 is installed, the spring force of torsion spring 4 can make sincere sub 5 to turn to latched position, sincere sub 5 front end has a spacing end face can spacing end face is blocked on the stroke moving to closing position of roller 6 in latched position; On pedestal, be provided with the spacer pin 3 that can limit sincere sub 5 latched positions.
Further can also be arranged to curved surfaces at the confined planes of sincere sub 5 ends, guarantee enough part strength and Mechanical Reliability, reduce unlocking resistance.
