Description
Technical field
The present invention relates to a kind of magnetic force lock, relate in particular to a kind of mini mechanical magnetic force lock.
Background technology
Existing a kind of small-sized magnetic machinery door latch structure is as shown in Figure 1; Knuckling rod 2 is set on the substrate 1 of a door-plate in opposed in opposite directions two door-plates; Both sides at knuckling rod 2 are provided with iron plate 12, and columnar spherical cavity 7 being set on another piece door-plate and being nested with can axially movable locating snap ring 6 in spherical cavity 7 peripheries.Wherein, said knuckling rod 2 is for being the cylindrical rod of ball perpendicular to the protruding end of door-plate, and the bulb diameter of knuckling rod 2 ends is greater than body diameter, on locating snap ring 6, with iron plate 12 corresponding positions magnet 10 is being set.This existing magnetic machinery door lock has been realized reaching big door leaf engaging force with little electromagnetic force conversion; After cutting out, must mandate could open by door leaf with ways such as Electromagnetic Control; Smooth operation, convenience, remote-controlled.
The volume of this existing small-sized machine magnetic force lock has lower limit, and the more little magnetic force face of small product size is more little, and the more little magnetic force of magnetic force face is more little, and product can't be locked when the volume that therefore need lock was too small.
Summary of the invention
The technical problem that the present invention will solve provides the safer mini mechanical magnetic force lock of a kind of more compact structure.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of mini mechanical magnetic force lock, comprise the support of door one side and from the support the pulling plug of vertical protrusion, and the magnet of door opposite side, be fixed on the magnet and upper shed can be inserted the sleeve of pulling plug and is nested with at the peripheral locating snap ring of sleeve.Wherein, locating snap ring is fixed in the iron plate of magnet top and can moves axially with respect to sleeve.Spacing connector one end is fixed on the magnet, and the other end inserts the perforate that iron plate is gone up correspondence position, and spacing connector is nested with spring outward, and spring plays the effect that magnet and iron plate are setovered each other.
For above-mentioned mini mechanical magnetic force lock, sleeve is fixed on the magnet as follows: lower cartridge is fixed on the pedestal of magnet below through the bottom connector.
For above-mentioned mini mechanical magnetic force lock, the bottom connector that passes magnet will overlap tube bottom and pedestal is resisted against the magnet above and below respectively.
For above-mentioned mini mechanical magnetic force lock, spacing connector is two stop screws that are positioned at the sleeve both sides, and two stop screws respectively are nested with spring outward.
For above-mentioned mini mechanical magnetic force lock, magnet is electric lost magnet.
Compared with prior art, the main advantage of technical scheme of the present invention is following:
1, the magnet of monoblock replaces original iron plate and is arranged on the volume that two blocks of magnet in the iron plate can further dwindle mechanical magnetic force lock in the mechanical magnetic force lock construction of the present invention, so product can be applicable to the field of newly guarding against theft such as furniture, automatic door, automobile etc.
2, the set-up mode of spring matches with the shape and structure of iron plate and magnet, further dwindles the volume of mechanical magnetic force lock.
3, the structure of pulling plug support one side is more succinct in the mechanical magnetic force lock construction of the present invention, and volume is littler.

Fig. 2 is the explosive view of the described mini mechanical magnetic force lock of one embodiment of the invention;
Fig. 3 illustrates the unlocking condition of the mini mechanical magnetic force lock of Fig. 2;
Fig. 4 illustrates the locking state of the mini mechanical magnetic force lock of Fig. 2.
The specific embodiment
Like Fig. 2, Fig. 3 and shown in Figure 4, the described mini mechanical magnetic force lock of one embodiment of the invention comprise the support 1 of door one side and from the support 1 pulling plug 2 and the door opposite side of vertical protrusion magnet 10, be fixed on the magnet 10 and upper shed can be inserted the sleeve 7 of pulling plug 2 and is nested with at the peripheral locating snap ring 6 of sleeve 7.Wherein, the termination of pulling plug 2 forms flange.The mechanism in the aperture that having on sleeve 7 and the locating snap ring 6 works in coordination regulates these sleeve 7 internal cavities; This mechanism comprises a plurality of circular holes that have on sleeve 7 sidewalls on the one hand; The ball of in each circular hole, placing 9; Side wall inner surfaces at locating snap ring 6 forms step on the other hand, and the aperture, top of the internal cavities of locating snap ring 6 is littler than lower part aperture.Locating snap ring 6 is fixed in the iron plate 5 of magnet 10 tops and can moves axially with respect to sleeve 7.Spacing connector 3 one ends are fixed on the magnet 10, and the other end inserts the perforate of correspondence position on the iron plate 5, the spacing connector 3 outer springs 4 that are nested with, and spring 4 plays magnet 10 and iron plate 5 effect of biasing each other of making.
Preferably, spacing connector 3 is for being positioned at two stop screws on sleeve 7 both sides, and two stop screws respectively are nested with spring 4 outward, and spring 4 can be arranged between magnet 10 and the iron plate 5, also can act between the screw cap and iron plate 5 of stop screw.
A plurality of circular holes on sleeve 7 sidewalls can be six, and ball 9 can be six steel balls.Bottom connector 8 can adopt screw.
Mini mechanical magnetic force lock of the present invention is the adhesive of adopting electromagnetism and the mode of release realizes the process of unblanking to lock, and can be that outage is opened the door or cut off the power supply and locks, and becomes the outage form of locking and needs only and change magnet 10 into electric lost magnet.Promptly when having a power failure, product is kept locking state to the theftproof that lock construction can further promote product in the outage.
As shown in Figure 3; Pulling plug 2 is inserted to sleeve 7 at closing time; Iron plate 5 receives spring 4 effects on the spacing connector 3 to keep certain distance with magnet 10; The large aperture part that is fixed on locating snap ring 6 inner chambers on the iron plate 5 is surrounded the part that sleeve 7 is provided with ball 9, so the termination flange of pulling plug 2 can further insert sleeve 7 through the position that sleeve 7 is provided with ball 9.Give magnet 10 power supplies or outage then; As shown in Figure 4, magnet 10 holds iron plate 5, and iron plate 5 overcomes the effect of spring 4 and moves to magnet 10; The small-bore part of locating snap ring 6 inner chambers is surrounded the part that sleeve 7 is provided with ball 9 simultaneously; Ball 9 is radially shunk in sleeve 7, and ball 9 is embraced the termination flange of pulling plug 2, thereby reaches the effect of locking a door.
