Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is perspective view of the present utility model
Description of reference numerals:
In figure: 1. guide rail, 2. guide bracket, 3. spring, 4. rotating shaft, 5. limiting plate, 6. go up connecting rod, 7. lower link, 8. go up door-plate, 9. play door-plate, 10. side plate, 11. chutes.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Shutter mechanism of switch cabinet described in the utility model, as shown in Figure 1, comprises linkage unit and valve;
Linkage unit comprises guide rail 1, rotating shaft 4, limiting plate 5 and connecting rod;
Guide rail 1 has two, be arranged in parallel, and on guide rail 1, symmetric position place is all rotatablely equipped with rotating shaft 4, and rotating shaft 4 end be positioned at outside guide rail 1 is all fixedly connected with connecting rod;
The limiting plate 5 that limiting rod drives rotating shaft 4 rotational angle size is installed with above rotating shaft 4 outside guide rail 1;
The described connecting rod other end is all fixedly connected on valve.
Specifically, described valve is arranged between biside plate 10, and on the inner side that biside plate 10 is corresponding, symmetry has chute 11, and described valve comprises the upper and lower door-plate 8,9 be hinged, slide and be arranged in chute 11 in upper door-plate 8 upper end, lower door-plate 9 bottom is fixedly installed between biside plate 8.
Be provided with below described guide rail 1 and match with guide rail 1, the guide bracket 2 of guide rail 1 movement along its length can be made.
Described connecting rod is two bar linkage structures, and lower link 7 is connected to rotating shaft 4 end, and upper connecting rod 6 is connected on lower door-plate 9.
This shutter mechanism of switch cabinet specific works principle is as follows: when entering service position from test position, the circuit breaker driving shaft be positioned on handcart drives guide rail 1 to do the movement away from valve direction along guide bracket 2, due to the position-limiting action of limiting plate 5, lower link 7 drags upper connecting rod 6 and moves down, thus drive lower door-plate 9 to be fixed on bottom between biside plate 8 for axle with it to rotate, and then drive and the upper door-plate 8 that is hinged of lower door-plate 9 along chute 11 slide downward, valve is opened the most at last, make circuit breaker contact arm enter in contact box, dynamic/static contact realizes occlusion.When returning test position from service position, linkage unit running order is contrary to the above, thus makes circuit breaker contact arm exit in contact box, and dynamic/static contact realizes being separated.
Preferably, be positioned in the rotating shaft 4 inside guide rail 1 and be all connected with spring 3, spring 3 other end is fixedly installed in inside guide rail 1.When test position enters service position, lower link 7 action drives rotating shaft 4 to rotate, thus make spring 3 be in extended state, when needs return test position from service position, rotating shaft 4 is under the effect of spring 3 restoring force, more easily realize revolution, and then drive the homing action of lower link 7, upper connecting rod 6, lower door-plate 9 and upper door-plate 8 successively, further ensure the smooth closedown of valve.
Preferably, described limiting plate 5 is triangle platy structure, can increase the connectivity robustness with guide rail 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
