Description
Technical field
The utility model relates to electromagnetic lock field, particularly a kind of magnetic suspension low power consumption electromagnetic lock.
Background technology
Electromagnetic lock is object common in daily life, and need for different functions, the design of electromagnetic lock is also varied.General electromagnetic lock structure as shown in Figure 1, the thinner end 71 of magnetic conductive rod 7 (can be made by the material of attraction) extend in coil 2, comparatively butt end 72 is exposed at outside coil 2, magnetic field is produced after coil 2 is energized, magnetic field is greater than the attraction of thinner end 71 compared with the attraction of butt end 72 to magnetic conductive rod 7, such magnetic conductive rod 7 will be moved to the left promotion dead bolt 6 and move to right, and locks after step 61 Compress Spring 5 of dead bolt 6; When magnetic field dissipate after coil 2 power-off, disappear to the magnetic force of magnetic conductive rod 7, spring 5 resilience, dead bolt 6 and magnetic conductive rod 7 are all popped into position, and now unblank.
The design size of above-mentioned magnetic conductive rod 7 needs the larger promotion that could realize dead bolt 6, the size of housing 1 is also comparatively large in requisition for what design, takes up room comparatively large, and only by the magnetic force moving magnetic conductive rod 7 that coil 2 produces, the power consumption of coil 2 is comparatively large, works long hours fragile.
Utility model content
Utility model object: for problems of the prior art, the utility model provides a kind of magnetic suspension low power consumption electromagnetic to lock, and can reduce coil power dissipation, extension coil working life, energy-conserving and environment-protective; And the global design size of electromagnetic lock can be reduced, internal construction is simple, takes up room less, low production cost.
Technical scheme: the utility model provides a kind of magnetic suspension low power consumption electromagnetic lock, comprise housing, coil, wire spool, magnet, spring and dead bolt, coil is enclosed within wire spool, wire spool is fixed in housing, magnet is positioned at wire spool, and magnet can move around in the interstitial hole in wire spool; One end of dead bolt leans against magnet one end and is positioned at housing, and the other end of dead bolt reaches hull outside; Spring is connected to dead bolt and is positioned on one end of housing.
Preferably, the two ends of described spring effectively contact with dead bolt with housing respectively.
Preferably, described spring is big spring.
Operating principle and beneficial effect: can magnetic field be produced when the coil is energized, magnetic field can produce repulsive force (if the magnetic field that coil produces produces magnet is attraction to magnet, then the both positive and negative polarity of coil electricity is exchanged), magnet will move to left promote dead bolt move to left, dead bolt moves to left and namely can realize locking by holddown spring, when magnetic field dissipate after coil blackout, disappears to the repulsive force of magnet, dead bolt and magnet spring back to original position under the action of the spring, are now unlocking conditions.The shape of visible magnet only needs simple cuboid, and length can be designed to very short, and needs compared with longer magnetic conduction iron in prior art, and the internal construction of this electromagnetic lock is more simple, and taking up room, it is a lot of to also reduce; In addition, because magnet itself has the magnetic field with coil equidirectional, make to have a repulsive force therebetween, the magnetic field force produced with relying on coil in prior art is to compared with the attraction of magnetic conductive rod, the power consumption of coil is less, thus making the energy-conserving and environment-protective more of this electromagnetic lock, the life-span is longer.
Accompanying drawing explanation
Fig. 1 is the internal construction schematic diagram of electromagnetic lock in prior art;
Fig. 2 is structural representation when magnetic suspension low power consumption electromagnetic is locked in unlocking condition in the utility model;
Fig. 3 is structural representation when magnetic suspension low power consumption electromagnetic is locked in locking state in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Present embodiments provide for a kind of magnetic suspension low power consumption electromagnetic lock, as shown in Figure 2, by housing 1, coil 2, wire spool 3, magnet 4, dead bolt 6 and spring 5 form, wire spool 3 is " work " font, centre is cylinder, both sides are disk, be fixed in housing 1, coil 2 is around in the middle cylinder of wire spool 3, magnet 4 is cuboid, right-hand member is positioned at the interstitial hole of wire spool 3, it is outside that left end reaches wire spool 3, the right-hand member of dead bolt 6 has a step 61, and this step 61 just to and against the left end of magnet 4, the left end of dead bolt 6 reaches outside housing 1 by the hole of housing 1 left side wall, overlap inside the left side wall of housing 1 and between step 61 and have spring 5.
Be worth together, in order to avoid there is delay phenomenon when unblanking or lock, the left end of spring 5 preferably effectively contacts with inside the left side wall of housing 1, and right-hand member preferably effectively contacts with on the left of step 61; In addition, in order to the effect of unblanking and lock making this electromagnetic lock can reach optimum, above-mentioned spring 5 preferably uses big spring.
This electromagnetic lock when unlocking condition as Fig. 2, spring 5 in the raw, after being energized to coil 2, coil 2 can produce magnetic field, attention will ensure that the magnetic direction of magnet 4 is identical with the magnetic direction that coil 2 produces, if difference, exchange the both positive and negative polarity be energized to coil 2, the magnetic field force that the magnetic field of coil 2 like this produces can have an effect repelled to magnet 4, now magnet 4 will be moved to the left and then be promoted left by dead bolt 6, now step 61 Compress Spring 5 of dead bolt 6, as shown in Figure 3, be compressed to a certain degree at spring 5, just locking of electromagnetic lock is completed after the left end of dead bolt 6 reaches the outside preset length of housing 1.
If give coil 2 power-off, the then magnetic field dissipate of coil 2 after electromagnetic lock is locked, also disappear to the magnetic field force of magnet 4, now spring 5 resilience, all springs back to original position by dead bolt 6 and magnet 4, as Fig. 2, is namely now unlocking condition.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.
