Description

A kind of electromagnetic lock

Technical field

The utility model relates to field of lockset, especially relates to a kind of electromagnetic lock.

Background technology

On market, electromagnetic lock is various informative, can be divided into two classes operating principle, switches to lock-out state after the energising of first kind electromagnetic lock by opening.Another kind of electromagnetic lock operating principle is then contrary, switches to opening after electromagnetic lock energising by lock-out state.A rear class electromagnetic lock only needs to provide the active force of unblanking of short time therefore, it is possible to reach the effect reducing power consumption, a rear class electromagnetic lock when electromagnetic force not by force or not lastingly time, locking-in state can not be switched to opening by electromagnetic lock fast.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, provides the electromagnetic lock that a kind of electromagnetic force is powerful, lasting and low in energy consumption.

It is that a kind of electromagnetic lock, comprises lock box, power supply, dead bolt, latch hook, return spring, electromagnet framework, electromagnet cover plate and actuating unit that the utility model solves the technical scheme that its technical problem adopts; Described dead bolt comprises upper lock tongue and lower dead bolt, and described upper lock tongue is all connected with lock box by turning cylinder with lower dead bolt, and described upper lock tongue and the lower dead bolt moving axis that all rotates rotates; The tip of the tongue of described lower dead bolt has upper lock tongue tongue mouth, the described size of upper lock tongue tongue mouth and the root of the tongue size of shape and upper lock tongue and shape suitable, described upper lock tongue is provided with return spring; Described actuating unit comprises electromagnetic coil, iron core, slide bar, pull bar screw and tower spring; Described electromagnetic coil is placed on iron core and slide bar, and iron core is fixed in electromagnetic coil, slide bar left end and iron core right-hand member suitable; The two ends of described pull bar screw are connected with slide bar right-hand member and the lower dead bolt root of the tongue respectively; Described electromagnet framework and electromagnet cover plate are fixed on lock box, and form electromagnetic wire ring recess, described electromagnetic coil is positioned in electromagnetic wire ring recess; Described tower spring is placed on slide bar and two ends and is connected with slide bar and electromagnet cover plate respectively; Described power supply is connected with electromagnetic coil.

Further, described power supply is electrically connected with four-way switch, and described four-way switch is fixed on lock box.

Further, described electromagnet framework and electromagnet cover plate are ironwork.

Compared with prior art, the utility model compact conformation, low cost of manufacture; Install simple and convenient, low in energy consumption, be provided with electromagnet framework and electromagnet cover plate, electromagnetic coil is easy to dismounting and can strengthens electromagnetic force, ensures that electromagnetic lock switches to opening fast and keeps the stability of its opening.

Detailed description of the invention

Embodiment

With reference to accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, the present embodiment comprises lock box 1, power supply, dead bolt, latch hook 2, return spring 3, electromagnet framework 4, electromagnet cover plate 5 and actuating unit; Dead bolt comprises upper lock tongue 6 and lower dead bolt 7, and upper lock tongue 6 is all connected with lock box 1 by turning cylinder with lower dead bolt 7, and upper lock tongue 6 and lower dead bolt 7 moving axis that all rotates rotates; The tip of the tongue of lower dead bolt 7 has upper lock tongue tongue mouth 14, the described size of upper lock tongue tongue mouth 14 and the root of the tongue size of shape and upper lock tongue 6 and shape suitable, upper lock tongue 6 is provided with return spring 3; Actuating unit comprises electromagnetic coil 8, iron core 9, slide bar 10, pull bar screw 11 and tower spring 13; Electromagnetic coil 8 is placed on iron core 9 and slide bar 10, and iron core 9 is fixed on the inner left end of electromagnetic coil 8, and slide bar 10 left end agrees with mutually with iron core 9 right-hand member; Pull bar screw 11 two ends are connected with slide bar 10 right-hand member and lower dead bolt 7 root of the tongue respectively; Be fixed on lock box after described electromagnet framework 4 assembles with electromagnet cover plate 5 and form an electromagnetic wire ring recess, described electromagnetic coil 8 is positioned in electromagnetic wire ring recess; Described tower spring 13 is placed on slide bar 10 and two ends and is connected with slide bar 10 and electromagnet cover plate 5 respectively; Described power supply is connected with electromagnetic coil 8.Power supply is connected with a four-way switch 12, and four-way switch 12 is fixed on lock box 1, and four-way switch 12 controls the "on" position of electromagnetic coil 8.

When electromagnetic lock is in opening, upper lock tongue 6 keeps an original state under the effect of return spring 3, and upper lock tongue 6 root of the tongue and lower dead bolt 7 the tip of the tongue are in released state, and lower dead bolt 7 and linkage part are in original state.

When needs locking electromagnetic lock, latch hook 2 is only needed to insert lock box 1, latch hook 2 contacts with upper lock tongue 6 the tip of the tongue, upper lock tongue 6 is forced to turn clockwise, latch hook 2 slowly by between upper lock tongue 6 the tip of the tongue and lock box 1 gap to lock box 1 internal motion, meanwhile upper lock tongue 6 root of the tongue contacts with lower dead bolt 7 the tip of the tongue and drives lower dead bolt 7 to rotate clockwise, and when upper lock tongue 6 root of the tongue slides to upper lock tongue tongue mouth 14, electromagnetic lock switches to lock-out state by opening.Under the effect of tower spring 13, upper lock tongue 6, lower dead bolt 7 and its linkage part are in a kind of stable state.

Only need electromagnetic coil 8 to be energized when electromagnetic lock is restored to opening by needs, now slide bar 10 axially moves to iron core 9 direction along electromagnetic coil 8, and then drive lower dead bolt 7 clockwise movement, final upper lock tongue 6 root of the tongue is separated with lower dead bolt 7 the tip of the tongue, under the effect of return spring 3, upper lock tongue 6 is returned to initial position, be returned to initial position at the effect drop shot 10 of tower spring 13, electromagnetic lock is in opening.

Electromagnetic lock is provided with electromagnet framework 4 and electromagnet cover plate 5, is fixed on lock box and forms an electromagnetic wire ring recess, just can be positioned in electromagnetic wire ring recess by electromagnetic coil 8 after the two being assembled, and electromagnetic coil 8 can conveniently dismounting; Electromagnet framework 4 and electromagnet cover plate 5 are ironwork, can strengthen electromagnetic force, ensure that electromagnetic lock switches to opening fast and keeps the stability of its opening.
