Abstract

The utility model relates to an electromagnetic lock with electromagnetism manipulation set bar, especially an electromagnetic lock suitable for mine emergency exit uses, its primary structure comprises mutually perpendicular's owner, vice lock to set up the locked groove corresponding with vice lock spring bolt when a main lock unblock on the main lock spring bolt. When the main lock and the auxiliary lock obtain unlocking or locking signals, the unlocking or locking can be realized instantly, and the device has the advantages of long service life, small starting current, good waterproof performance, simple structure, small volume, convenience in use and the like.

Description

Electromagnetic lock

The utility model relates to a kind of electromagnetic lock with electromagnetism operated lock bolt, particularly a kind of electromagnetic lock that is applicable to that mine mine safety door uses.

Disclose a kind of MQ1-3 tractive magnet in " simple and clear practical eelctrical engineering handbook " electromagnet one joint that Shanghai science tech publishing house publishes, this product mainly is made up of parts such as yoke, armature, coils.If adopt the safety door blocking device of this tractive magnet, its weak point: 1, because this tractive magnet water resistance extreme difference is difficult to the ambient conditions that is applicable to that the mine mine uses as occasions such as mine mines; 2, because this tractive magnet is put lock or the release work of will switching on for a long time, the life-span is short; 3, starting current is big; 4, complex structure, volume is big, installs inconvenient.

The purpose of this utility model provides the electromagnetic lock that just can realize release after a kind of starting current is little, moment switches on or put lock.

For achieving the above object, the technical solution adopted in the utility model is such: an end of the dead bolt of main lock is contained in the main coil centre bore, and with the main lock tongue vertical direction pair lock that is made of secondary coil, secondary lock dead bolt, stage clip, collection magnetism board is being set; When being set, master's lock release locks the corresponding locked groove of dead bolt with pair on main lock tongue.When electromagnetic lock obtained unlocking signal, main coil moment conducting produced high-intensity magnetic field, attracts main lock tongue, make main lock tongue withdraw from main lock locked groove, and itself by self-locking, had realized the permanent release of electromagnetic lock under the effect of pair lock dead bolt; When electromagnetic lock obtains putting lock signal, secondary coil moment conducting attracts secondary lock dead bolt, and electromagnetic lock is removed self-locking, and main lock tongue enters main lock locked groove under the effect of main lock stage clip, realize putting lock.

Because dead bolt one end is contained in the hub of a spool hole, seldom reveal between dead bolt and collection magnetism board in the magnetic field that coil is produced, and under the effect of identical rated current, tractive force is bigger, therefore, is keeping under the constant situation of tractive force, and starting current is just little.

Because the utility model has adopted above technical scheme, compared with prior art has the following advantages:

1, moment can realize putting lock or release for electricity, short time work, and the life-span is long;

2, because coil separates with dead bolt, and coil is easily realized sealing, water resistance is good;

3, starting current is little;

4, simple in structure, volume is little, and is easy to use;

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is an embodiment front view of the present utility model

As seen from Figure 1, Figure 2, present embodiment mainly is made of the major and minor lock that is integrated in one, and main lock is made of main coil 9, dead bolt 6, stage clip 5, collection magnetism board 10, and dead bolt 6 one ends are contained in the centre bore of main coil 9, stage clip 5 one ends withstand on the convex shoulder of dead bolt 6, and an end withstands on the inwall of shell 1.Secondary lock is made up of secondary coil 3, dead bolt 4, stage clip 8, collection magnetism board 2, and dead bolt 4 one ends are contained in the centre bore of secondary coil 3, and stage clip 8 one ends withstand on the secondary coil end face, and an end withstands on the shoulder of dead bolt 4.When master's lock release is set on dead bolt 6, with dead bolt 4 corresponding annular lock groove 7.Because dead bolt one end is contained in the hub of a spool hole, seldom reveal between dead bolt and collection magnetism board in the magnetic field that coil is produced, and under the effect of identical rated current, tractive force is bigger, therefore, is keeping under the constant situation of tractive force, and starting current is just little; Because the dead bolt of major and minor lock separates with major and minor coil, make major and minor coil easily realize sealing on the other hand, water resistance is good.When electromagnetic lock obtained unlocking signal, main coil 9 moment conducting produced high-intensity magnetic field, attract dead bolt 6, make dead bolt 6 withdraw from locked groove 11, and itself is because the effect of dead bolt 4, by self-locking, realized the permanent release of electromagnetic lock, when electromagnetic lock obtains putting lock signal, secondary coil 3 moment conducting, attract dead bolt 4, electromagnetic lock is removed self-locking, and dead bolt 6 enters locked groove 11, realizes putting lock.Because the utility model moment can realize putting lock or release for electricity, short time work, the life-span is long.The utility model is applicable to that also factory, hotel, universities and colleges etc. automatically put lock in the gate.

Claims
