Abstract

An electromagnetic drive lock comprises a lock box (1) with a box cover (6), an electromagnetic coil body (11), a moving core, a bolt spring (2), and a latch (8); the electromagnetic coil body (11) is fixed in the lock box (1); the moving core serving as a bolt (3) is disposed in the electromagnetic coil body (11); the bolt (3) is sleeved with the bolt spring (2); one end of the bolt spring (2) is abutted to the electromagnetic coil body (11), and the other end of the bolt spring (2) is positioned on the bolt (3); the latch (8) is provided with a lock hole (10) matching with the bolt (3). The electromagnetic drive lock is characterized in that the inside of the lock box (1) is provided with a limit slide at the front end of the bolt (3) and axially perpendicular to the bolt (3), a slider (5) is mounted in the limit slide, a spring (4) is disposed between the slider (5) and the box cover (6), and the latch (8) matches with the limit slide. The electromagnetic drive lock is compact in structure and low in overall cost; the bolt (3) and the latch (8) can be accurately positioned, and the electromagnetic drive lock is solid and reliable.

Description

Electromagnetic Drive lock

One, technical field

The present invention relates to one utilizes Current Control electromagnet to move that iron core (dead bolt) is flexible to cooperatively interact and realize the Electromagnetic Drive lock of opening with locking door leaf with snap close.This Electromagnetic Drive lock is specially adapted to the integrated storage facilities consisting of multiple independent lockers that the places such as workshop, market arrange.

Two, background technology

At present, the mounting means of known Electromagnetic Drive lock is that lock box is fixed on door leaf cover plate, by the snap fit on dead bolt and doorframe in lock box, pins locker.In the time of need to opening the door, by key manually or implement by modes such as electronic ciphers, and can realize by the spring spindle automatic opening door being located on doorframe and fanning.But because general doorframe takes up space all littlely, mounting spring push rod can take the usefull space, and both the uneconomical mistake multiple component that also increased, has increased fabrication and installation difficulty.

Three, summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, design a kind of simple in structure, stable performance, spring spindle is integrated in the Electromagnetic Drive lock in lock box.Thereby can reduce component, compact conformation, saves installation work-hour, reduces holistic cost.

Basic ideas of the present invention are: in lock box, be positioned at dead bolt front end place and be provided with spacing slideway, and spacing slideway is axially vertical with dead bolt, in spacing slideway, slide block is housed, and between slide block and lid, spring is housed; Snap close coordinates with spacing slideway.Like this, when closing door leaf, snap close is by slide block toward interior top, and spring is compressed, and dead bolt departs from slide block and enters and in the lockhole on snap close, realize locking door leaf under the effect of latch bolt spring; When needs are opened door leaf, give electromagnet moment energising, under the effect of electromagnetic force, dead bolt is toward indentation in electromagnetic coil, and latch bolt spring is compressed, and dead bolt departs from lockhole, and spring reset forces door leaf to be opened rapidly to snap close reaction force; When door leaf is opened rapidly, electromagnet is power-off also, and latch bolt spring resets, and dead bolt resets thereupon and withstands on slide block.

The present invention is specifically achieved through the following technical solutions:

An Electromagnetic Drive lock, comprising:

With the lock box of lid, be fixed on the electromagnetic coil body in lock box, the moving iron core that forms dead bolt is housed in electromagnetic coil body, on dead bolt, cover has latch bolt spring, latch bolt spring one end to withstand on electromagnetic coil body, and the latch bolt spring other end is positioned on dead bolt;

Snap close, and on snap close, have lockhole, dead bolt coordinates with lockhole;

It is characterized in that: in lock box, be positioned at dead bolt front end place and be provided with spacing slideway, and spacing slideway is axially vertical with dead bolt, in spacing slideway, slide block is housed, and between slide block and lid, spring is housed;

Snap close coordinates with spacing slideway.

The invention has the beneficial effects as follows, this Electromagnetic Drive lock construction compactness, holistic cost is low.Dead bolt, snap close accurate positioning, and solid and reliable.It is few that this Electromagnetic Drive lock takies the usefull space.

Four, accompanying drawing explanation

Five, the specific embodiment

Below in conjunction with accompanying drawing, the present invention is described further.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of Electromagnetic Drive lock, comprising:

Lock box 1 with lid 6, be fixed on the electromagnetic coil body 11 in lock box 1, the moving iron core that forms dead bolt 3 is housed in electromagnetic coil body 11, on dead bolt 3, cover has latch bolt spring 2, latch bolt spring 2 one end withstand on electromagnetic coil body 11, and latch bolt spring 2 other ends are positioned on dead bolt 3;

Snap close 8, and on snap close 8, have lockhole 10, dead bolt 3 coordinates with lockhole 10;

It is characterized in that: in lock box 1, be positioned at dead bolt 3 front end places and be provided with spacing slideway, and spacing slideway is axially vertical with dead bolt 3, and slide block 5 is housed in spacing slideway, between slide block 5 and lid 6, spring 4 is housed;

Snap close 8 coordinates with spacing slideway.

Operating principle of the present invention is:

During door opening, electromagnet is without electricity, and spring 4 makes slide block 5 in Fig. 5 state in Local Contraction state, and slide block 5 now blocks dead bolt 3 and stops dead bolt 3 to stretch out, and latch bolt spring 2 is in compressive state.

Close the door in process, the effect that makes snap close 8 transmit power to slide block 5 by external force, extruding slide block 5, the support spring 4 of slide block 5 becomes complete compressive state from Local Contraction state shape, slide block 5 positions are moved to and no longer block dead bolt 3, latch bolt spring 2 changes Local Contraction state into by complete compressive state, makes dead bolt 3 insert lockhole 10 and realizes locking, sees Fig. 4 state.

Open the door in process, the energising of electromagnet moment realizes dead bolt 3 and shrinks, and latch bolt spring 2 is complete compressive state by Local Contraction state-transition, and spring 4 changes Local Contraction state into by complete compressive state.Because snap close 8 is all the time in stationary state, under the effect of spring 4, make door flick realization and open the door, lock box 1 inner body is got back to Fig. 5 state.
