The purpose of this utility model is to provide a kind of chopper spring mechanism machinery anti-bouncing device, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model following technical scheme of offer: a kind of chopper spring mechanism machinery anti-bouncing device，Including mechanism's side plate、Electric magnet and axle，The side of described mechanism side plate is provided with electromagnet mounting plate by screw，The both sides of described electric magnet are separately installed with right guide plate and left guide plate，And electric magnet is arranged on the surface of electromagnet mounting plate by left guide plate，The dynamic iron core ends screw of described electric magnet is linked with moving mass，Described moving mass passes through axle sleeve equipped with little buckle，Little buckle return spring is installed at the middle elongated hole of described little buckle，And the another side of little buckle contacts with moving mass surface，The horixmtal long hole that the two ends of described axle are run through on right guide plate and left guide plate carries out guide-localization，Described energy storage keeps buckle to be arranged on the side of mechanism's side plate by axle，And energy storage keeps the top of buckle to contact with the bottom of the horixmtal long hole one end on right guide plate and left guide plate，Described energy storage holding buckle can rotate and pass through buckle return spring and contact and spacing bottom right guide plate and left guide plate around buckle axle.
Preferably, described electromagnet mounting plate is approximately U-shaped, and the electric magnet installed surface of electromagnet mounting plate is provided with two groups of electric magnet installing holes.
Preferably, described energy storage keeps buckle to be double-decker, and energy storage keeps the double-decker of buckle to be connected by buckle axle.
Preferably, described moving mass is rectangle, and the centre of moving mass has elongated hole to be provided with little buckle return spring.
Compared with prior art, the beneficial effects of the utility model are: this utility model prevents the generation of jump from the frame for movement within operating mechanism, can prevent from electrically jumping, and also can prevent from manually jumping, and not conflict with comprehensive protector.
Accompanying drawing explanation
Fig. 1 is that mechanical anti-jump parts assemble schematic diagram.
In figure: 1 mechanism's side plate, 2 electromagnet mounting plates, 3 electric magnet, 4 right guide plates, 5 left guide plates, 6 energy storage keep buckle, 7 little buckle return springs, 8 axles, 9 buckle axles, 10 little buckles, 11 moving mass, 12 buckle return springs.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，A kind of technical scheme of this utility model offer: a kind of chopper spring mechanism machinery anti-bouncing device，Including mechanism's side plate 1、Electric magnet 3 and axle 8，The side of mechanism's side plate 1 is provided with electromagnet mounting plate 2 by screw，Electromagnet mounting plate 2 is approximately U-shaped，And the electric magnet installed surface of electromagnet mounting plate 2 is provided with two groups of electric magnet installing holes，Improve the convenience that electric magnet 3 is installed，The both sides of electric magnet 3 are separately installed with right guide plate 4 and left guide plate 5，And electric magnet 3 is arranged on the surface of electromagnet mounting plate 2 by left guide plate 5，The dynamic iron core ends screw of electric magnet 3 is linked with moving mass 11，Moving mass 11 is rectangle，Moving mass 11 is set with little buckle 10 by axle 8，The centre of little buckle 10 is provided with little buckle return spring 7，And the another side of little buckle 10 contacts with moving mass 11 surface，The horixmtal long hole that the two ends of axle 8 are run through on right guide plate 4 and left guide plate 5 carries out guide-localization，Energy storage keeps buckle 6 to be arranged on the side of mechanism's side plate 1 by screw，And energy storage keeps the top of buckle 6 to contact with the bottom of the horixmtal long hole one end on right guide plate 4 and left guide plate 5，Energy storage holding buckle 6 can rotate around buckle axle 9 and pass through buckle return spring 12 and contact and spacing bottom right guide plate 4 and left guide plate 5，Energy storage keeps buckle 6 to be double-decker，And energy storage keeps the double-decker of buckle 6 to be connected by buckle axle 9，It is capable of energy storage to keep, between buckle 6 difference, a certain degree of rotation to occur.
Operation principle: when spring mechanism storage 6 can be complete, electric magnet 3 obtains end that is electric or that be manually pressed by dynamic iron core then makes the dynamic iron core of electric magnet 3 move right, drive the little buckle 10 horixmtal long hole along right guide plate 4 and left guide plate 5 to move right, promote energy storage to keep crimp on buckle 6 to make energy storage keep buckle 6 to rotate clockwise and open snap close and closed a floodgate；When energy storage keeps buckle 6 to rotate to certain angle, little buckle 10 will slip over from the upper side, and now energy storage keeps buckle 6 will to return to original position under the effect of buckle return spring 12；Can carry out during now mechanism's energy storage again keeping and snap close, prevent chopper from again closing a floodgate, little buckle 10 slips over energy storage and keeps after buckle 6, if electric magnet 3 dead electricity or manually unclamp, the least buckle 10 rotates around axle 8 and reset under the return spring effect of electric magnet 3 original state；Wait reclosing command next time.I.e. when, under the state that electric magnet 3 iron core does not reset, energy storage keeps buckle 6 still can reset, it is achieved that the function that machinery is anti-jump.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
