Abstract
The utility model relates to an electromagnetic lock, which is composed of a lock case, an electric magnet, a draw rod for an armature iron and a lock bolt. A manual switch knob and reverberatory force springs, which are fixed by two fixed clamps, are arranged on the draw rod, the lock bolt is arranged on the other corresponding end of the draw rod, and the lock bolt which is a flat cylinder is inserted with a rotating shaft on the center. The rotating shaft is inserted with torsion springs, a circular hole is arranged on one end of the lock bolt corresponding to the draw rod, and a fan-shaped concave mouth arranged on the other side is corresponding to the upper pillar of a door frame. The electric magnet is powered on, the draw rod is pulled out, and the door is provided with the rotation of the lock bolt; the closed door is automatically locked. The utility model has the advantages that the structure is simple, the installation and the application are convenient, and the opening of the lock can be controlled from a long distance.
Description
The utility model belongs to a kind of electric door lock.
At present general family and the employed door lock of storehouse all are a kind of standard machinery structure lock or coded lock, its structure is made of lock body, lock core and snap, the branch that size is respectively arranged, general structure is identical, advantage be simple in structure, production and processing is easy, cost is low, but shortcoming is to unblank at a distance, the place of garden is arranged especially, far from the Qianmen, gone in front of the door to unblank, use inconvenience, for service units such as some hostels, hotels, the room is a lot, can manage concentratedly, if take precautions against difficult management with monolock.
In order to solve the inconvenience of unblanking at a distance, the purpose of the utility model provides a kind of electromagnetic lock, adopts electromagnetic actuation and discharges and unblank, and has effectively solved the problem of unblanking at a distance.
Structure design of the present utility model is achieved in that its structure of this electromagnetic lock is by lock housing, electromagnet, armature pull bar and dead bolt four parts are formed (as shown in Figure 1), its connection is: the side at base is equipped with electromagnet, corresponding with electromagnet is the armature pull bar, on pull bar, be with return spring, two geometrical clamps are housed on the pull bar simultaneously, be equipped with on pull bar in the pull bar intermediate vertical and manually remove button, be connected with dead bolt with the armature pull bar, dead bolt is flat cylinder, the center is installed with rotating shaft, two ends are fixed on the base of lock, be installed with the dead bolt torsion spring in rotating shaft, have a circular hole in the corresponding side with the armature pull bar of dead bolt, the insertion circular hole has been in harmony in the pull bar termination, opposite side at dead bolt has a scallop, and the column on the corresponding doorframe just inserts (as shown in Figure 3).
Its operating principle: when door is closed, door lock is a lock-out state, column on the doorframe inserts in the scallop of dead bolt, at this moment in the circular hole of insertion dead bolt has been in harmony in the termination of armature pull bar, the pin tongue can't be rotated, pull bar is because the effect of return spring, can not extract automatically, when opening the door, the electromagnet energising, the armature pull bar is inhaled, extract from dead bolt the termination of pull bar, this moment, the effect owing to torsion spring on the dead bolt made the dead bolt rotation, to the reaction of doorframe column, door was opened automatically a little, lock the state of being out this moment, manually remove button if left alone without help electricity can be moved, pull bar is extracted, door is opened automatically.
The utility model and existing lock relatively have following advantage: simple in structure, easy to install, use electromagnet can be unblanked in remote operation, is suitable for tame garden front yard and opens the door and large-scale hotel, hostel use.
Detailed structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a kind of structure principle chart of electromagnetic lock;
Fig. 2 is a kind of locking closure structure chart of electromagnetic lock;
Fig. 3 is a kind of dead bolt structure chart of electromagnetic lock.
Its structure is known by Fig. 1, (1) is the electromagnetic lock outer casing base, (2) be electromagnet coil, be fixed on the base (1), draw from a side by lead, (3) be the armature pull bar, return spring (5) is housed above, the center is equipped with and manually removes button (4), fixing by two geometrical clamps (10), and make pull bar (3) at geometrical clamp (10) but in move left and right, in another end of pull bar (3) dead bolt (6) is housed, the centre is installed with dead bolt rotating shaft (9), button spring (7) is housed in rotating shaft (9), rotating shaft (9) two ends are fixing by fixed block (8), and (11) are doorframe column, are known by Fig. 2, removing when button (4) is unblanked when not having electricity in the middle of the locking closure used, know that by Fig. 3 dead bolt (6) is an oblate post, when pull bar (3) is extracted, dead bolt (6) rotation, door pillar is thrown off, and this moment, door was opened, and has only when electromagnet energising door just can be opened.
Claims (4)
1, a kind of electromagnetic lock, the structure that it is characterized in that electromagnetic lock is made up of lock housing (1), electromagnet (2), armature pull bar (3) and dead bolt (6) four parts, its connection be the side at base (1) be equipped with electromagnet (2) corresponding with electromagnet (2) be armature pull bar (3), in another end of pull bar (3) dead bolt (6) is housed.
