Embodiment

Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:

As Fig. 1, Fig. 2, shown in Fig. 3, a kind of universal circuit breaker drawer seat, it comprises cabinet, Shell of circuit breaker 1, rocker assembly 2 and the rotating shaft 3 by rocker assembly 2 driven rotary, also comprise an interlocking gear, this interlocking gear comprises pin 4, swing arm 5 and lever 61, described rotating shaft 3 two ends are through housing sidewall 11, exposed outside housing sidewall 11, pin 4 is hinged on outside housing sidewall 11, swing arm 5 lower end fixed is in rotating shaft 3, with rotating shaft 3 linkage rotation, upper end is provided with clamping block 51, this lever 61 middle-end 612 is fixed on pin 4, and with this middle-end 612 for fulcrum, tail end 613 is against the clamping block 51 in swing arm 5, tail end 613 is driven to decline by swing arm 5, front end 611 is connected with the lock on cabinet by the steel wire rope of vertical socket, also comprise the return unit ordering about lever 61 tail end 613 and rise.

As shown in Figure 7, rocker assembly 2 comprises handle, screw rod 21, push pedal 22, base plate 23 and gear 24, and gear 24 is socketed in rotating shaft, and tooth engages with base plate 23, base plate 23 is connected with push pedal 22, there is threaded engagement, swinging handle in screw rod 21 and push pedal 22, screw rod 21 is rotated, drive push pedal 22 translation, and then drive base plate 23 translation, thus realize gear 24 and engage with base plate 23 and rotate, finally drive rotating shaft 3 rotates.

Omnipotent breaker divides work, test, separation three states, operating state, and the binding post made by rocker assembly 2 is normally connected, and busbar also normally connects, and omnipotent breaker normally works; Trystate, the binding post made by rocker assembly 2 is normally connected, and busbar does not connect, and at this time can do a little auxiliary test operation; Released state, the binding post made by rocker assembly 2 is not connected, and busbar does not connect yet, and omnipotent breaker does not work.

Described swing arm 5 upper end is integrally provided with arm 55, minor axis 56 and clamping block 51, arm 55, minor axis 56 and clamping block 51 form the first groove 58 of inlay card lever 61 tail end 613, described return unit is the torsion spring 7 be enclosed within pin 4, and this torsion spring 7 one end is fixed in fixing hole 54, other end support lever 61.By rocker assembly 2, drawout chassis is shaken out, circuit breaker is made to be in released state, now, rotated by rotating shaft 3, drive swing arm 5 to rotate, thus drive lever 61 tail end 613 of inlay card on the first groove 58 to decline, due to lever principle, rising in lever 61 front end 611, thus makes steel wire rope be in releasing orientation, realize cabinet and lock the state opened, make it to open; By rocker assembly 2 drawout chassis shaken into, circuit breaker is made to be in test or operating state, now, rotated by rotating shaft 3, after driving swing arm 5 to rotate, the restoring force of torsion spring 7 drives lever 61 tail end 613 to rise, due to lever principle, lever 61 front end 611 declines, thus tense wire rope, realize the state that cabinet pins, make it to open.

As Fig. 4, shown in Fig. 5, described swing arm 5 upper end integrally, be arranged with arm 55, minor axis 56 and clamping block 51, the second groove 59 in the slide rail 53 of the formation inlay card relative with the first groove 58 in housing sidewall 11, this second groove 59 forms slippage with this slide rail 53 and coordinates, the two ends of swing arm 5 are fixed with the inlay card of the second groove 59 and slide rail 53 and rotating shaft 3, make it to be fitted on outside housing sidewall 11, ensure swing arm 5 when rotated, can on one face, skew can not be produced, otherwise long-term skew can affect rotating shaft 3 produces skew, the final rocker assembly 2 that affects shakes accuracy into shaking out.

Described swing arm 5 upper end is integrally provided with projection 57, described projection 57 is fixed between two-arm 55, also comprise one end and be socketed in spring 52 on projection 57, the other end of this spring 52 is fixed in the fixing hole 54 in housing sidewall 11, and steel wire rope is from releasing orientation to tension, the rotation of recovery elasticity to swing arm 5 of extension spring is utilized to assist, extension spring is fixed in swing arm 5 by projection 57, can make extension spring stress balance, can not produce skew, swing arm 5 unitary design, equipment is convenient.

Described front end 611 is latch hook, adopts latch hook, steel wire rope can be prevented from this end landing.Certainly, also can recessing between front end 611, to fix steel wire rope.

Described latch hook is through limit base 62, be in outside limit base 62, left and right restriction is carried out in the front end 611 of limit base 62 pairs of levers 61, to fit housing sidewall 11 to make lever 61, limit base 62 carries out upper and lower displacement restriction to the front end 611 of lever 61 simultaneously, with the snap fitting structure making lever 61 can not damage tail end 613 because of the unrestricted of front end 611, even damage rotating shaft 3, and then make whole circuit breaker cisco unity malfunction.

Described door interlocking gear is symmetricly set on outside housing sidewall 11, and both sides are all provided with an interlocking gear, so can more firmly realize cabinet lock status.

Also comprise symmetrically arranged door handle 12, this door handle 12 adopts metal material, increases durability.

As shown in Fig. 1, Fig. 6, in addition, also comprise the gear mesh 8 be symmetricly set on inside housing sidewall 11, described gear mesh 8 adopts the tooth engaged completely, in omnipotent breaker, gear mesh 8 forms its transmission mechanism, changes gear ratio, makes the speed of busbar from separation point position to service position accelerate thus.

Below described by reference to the accompanying drawings embodiment is only the preferred embodiment of the present invention, and the restriction not to protection scope of the present invention, and any improvement done based on the present invention's spirit all ought within scope.
