The device includes the rotating axes base equipped with breaker and acting contactor which is mounted in the cavum of the rotating axes base, the acting contactor possesses a pair of rotating arm which can rotate around the core of the rotating axes base, contacting point is set at front end of the rotating arm; two reeds are set in position which is corresponding with two rotating arms, the rear end of the reed are limited on the rotating axes base, the front segment of the reed is a bend segment which bends to the center of the rotating axes, compressed elastic is set between the bend segments; sliding axes is fixed at the rotating arm, the sliding axes is pressed to outer side of the reed. The invention is simple, convenient to assembly, reliable to use.

Description

Reed rotating axis locking mechanism
Technical field
The invention belongs to low voltage electrical equipment, relate to a kind of reed rotating axis locking mechanism that is used for low-voltage circuit breaker.
Background technology
In the common low-voltage circuit breaker course of work, when bigger failed shorted electric current occurring in the circuit, before the operating mechanism action, moving contact overcomes contact pressure and should scold out in advance under the active force of electrodynamic repulsion force, and the rotating shaft transfixion.The effect of rotating axis locking mechanism is exactly, dynamic and static contact scold reach large opening after, make moving contact rest on maximum position, under the effect of operating mechanism, thread off at release, reduce and fall to cause arc reignition to avoid moving contact to hinder short circuit current for some reason.The existing circuit breaker rotating axis locking mechanism generally has two kinds of forms: a kind of form is the moving contact cam structure, and it is when moving contact is scolded out, and blocks cam surface by the effect axle, and it blocks simple in structure, but reliability is lower; Another kind of form is a bar linkage structure, its effect connecting rod back and forth movement between the dead point, this form block the architecture complexity, technological requirement is very high, and difficulty is installed.
Summary of the invention
Technical problem to be solved by this invention is, a kind of simple in structure, easy to assembly, circuit breaker reed rotating axis locking mechanism that dependability is high is provided.
Reed rotating axis locking mechanism of the present invention includes the rotating shaft matrix of circuit breaker and is installed in moving contact in the cavity of rotating shaft matrix, moving contact has a pair of pivoted arm of matrix center rotation around the shaft, and the inner side edge front end of pivoted arm is provided with the contact that cooperates with fixed contact; With two corresponding positions of cursor, be provided with two reeds, the rear end of reed is spacing on the rotating shaft matrix, the leading portion of reed is one section bending section to the bending of rotating shaft center position, the start point distance center of rotation of bending section is provided with between the bending section of two reeds and makes two outside open compression springs of reed farthest; In addition, the leading portion of reed also has notch longitudinally, and the cursor of moving contact is arranged in notch, is fixed with sliding axle on cursor, and sliding axle is pressed in the outside of reed.
The present invention is simple in structure, easy for installation, reliable in action is good; This structure in the course of the work, when dynamic and static contact is scolded out because of bigger electrodynamic repulsion force, after the starting point of crossing bending section is peak, sliding axle operation on the pivoted arm arrives the bending section of reed, because compress spring and be compressed this moment, therefore the bending section of reed slopes inwardly, and makes sliding axle can rest on bending section, and moving contact falls after rise and causes arc reignition when having prevented that electrodynamic repulsion force from weakening.
Description of drawings

Fig. 2 is the sectional structure schematic diagram of the present invention when dynamic and static contact closure;
Fig. 3 is the sectional structure schematic diagram of the present invention when dynamic and static contact disconnects;
Embodiment
As shown in the figure, this rotating axis locking mechanism includes breaker rotating axis matrix 1 and moving contact 2, moving contact is installed in the cavity 11 in the rotating shaft matrix, and the pivoted arm 21 of the moving contact center of matrix around the shaft rotates, and the inner side edge front end of pivoted arm 21 is to be used for the contact 22 that cooperates with fixed contact 3.Two pivoted arms lay respectively in vertical notch 41 on two reeds 4, running through 5 of sliding axles that are fixed on the pivoted arm is pressed on the lateral surface of reed, and at the medial surface of reed, be provided with compression spring 6 between the bending section 42 of two reed leading portions, the compression spring the axial bilateral symmetry of moving contact be provided with a pair of, make the inside and outside both sides of reed be compressed spring and reed pressure holding respectively, the rear end of reed then is limited on the rotating shaft matrix.
When dynamic and static contact was positioned at normal make position, as shown in Figure 2, the sliding axle 5 on the moving contact was positioned at the back segment of reed 4, and the bending section 42 of reed leading portion outwards opens under the effect of compression spring 6; When having bigger fault current to pass through in the dynamic and static contact, moving contact 2 is scolded out under the electrodynamic repulsion force effect, sliding axle 5 moves to its leading portion on reed 4 surfaces, the elastic force that overcomes the compression spring inwardly is incorporated into reed, after sliding axle is crossed the bending section 42 of peak arrival reed, because this moment, bending section sloped inwardly, thereby sliding axle can rest on bending section, prevented that moving contact from falling after rise and cause arc reignition.
