Abstract
The utility model discloses an electromagnetic lock, which is that the two ends of an electromagnet the two ends of a continue iron plate are respectively provided with upper teeth and lower teeth. The utility model is mainly composed of an electromagnet and a continue iron plate. The utility model is characterized in that the two ends of the electromagnet are provided with the upper teeth, and the two ends of the continue iron plate are provided with the lower teeth. The movable terminal box has the advantages of artful design and reasonable structure; the utility model uses the saw tooth engaging principle for accurately positioning; thereby, the door can be reliably locked, and the safety can be greatly improved.
Description
The utility model relates to a kind of lockset, particularly relates to a kind of electromagnetism shearing lock that is provided with upper and lower teeth at the electromagnet and the iron plate two ends of continuing.
Electromagnetism shearing lock is used for the occasion of the positive and negative bidirectional opening of door mostly.Is made up of the electromagnet and the iron plate two large divisions that continues, wherein electromagnet is installed in the crosspiece of doorframe or straight grade, with the iron plate adhesive mutually that continues of door leaf top or side.The fundamental diagram of traditional magnetic force lock walks to doorframe following time when door leaf is subjected to the inertia force effect as shown in Figure 1, is subjected to magneticaction, electromagnet 10 with continue iron plate 20 adhesives, utilize the U groove of electromagnet 10 housings, reach the purpose of pinning.And when the door leaf location is not placed in the middle, the phenomenon of Fig. 2 then can occurs, thereby can not pin exactly.In addition, live, have an active force that pushes to act on when last, can make the iron plate of continuing that deflection takes place downwards, and door can not be pinned reliably, as shown in Figure 3 when door lock.
The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, the magnetic force lock that door can be pinned reliably.
The technical solution of the utility model is, a kind of electromagnetism shearing lock, and mainly by electromagnet with continue iron plate forms, its characteristics are: the two ends of electromagnet are provided with teeth, are provided with time teeth correspondingly at the two ends of the iron plate of continuing.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, used the principle of engagement to locate exactly, thereby door is pinned reliably, improved the safety of using significantly, the tool promotional value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the fundamental diagram of traditional electromagnetism shearing lock;
Fig. 2 is the accurately schematic diagram during locking-in state of traditional electromagnetism shearing lock;
Fig. 3 is that traditional electromagnetism shearing lock pins back chance external force, the schematic diagram when continuing the iron plate deflected condition;
Fig. 4 is the structural representation of the utility model electromagnet;
The structural representation that Fig. 5 continues iron plate for the utility model;
Fig. 6 is the structural representation of the utility model electromagnet side direction when continuing the iron plate adhesive.
Referring to Fig. 4, the two ends of electromagnet 30 of the present utility model are provided with teeth 31, and the top of last teeth 31 is provided with guiding angle surface 311.Referring to Fig. 5, and the two ends of the iron plate 40 of continuing are provided with down teeth 41 with it accordingly, and the top of following teeth 41 is provided with guiding angle surface 411.Referring to Fig. 6, when electromagnet 30 with continue iron plate 40 mutually during adhesive, because the buffering of guiding angle surface and the effect of guiding can make down teeth 41 be embedded in exactly in the teeth 31, thereby reach the purpose that door leaf is pinned quickly and accurately.
