Abstract

The utility model relates to an electromagnetic lock, wherein, a lock bolt is arranged in an electromagnetic lock body, the lock bolt is provided with a reset spring and a positioning circlip, and the tail of the lock bolt is arranged in an electromagnetic coil. The back end of the electromagnetic lock body is provided with a magnetic cover, and a flute which is matched with the front end of the lock bolt is arranged on a fastening device of the electromagnetic lock. An electromagnetic converting device of the utility model and a door lock are integrated, and the utility model has the advantages that the volume is small, and the cost is low. The lock can be connected with different control systems and mechanical type switches, and the alternating current and direct current can be both used.

Description

Electromagnetic lock

The utility model relates to a kind of Electromagnetic lock.

At present, the Electromagnetic lock that uses on safety cabinet, the strongbox partly combines by power section and mechanical lock head, these two parts generally adopt the finished product of specialized factory, owing to be subjected to the restriction of trimmed size, can not design as required, thereby make volume excessive, shape is long, easily cause waste, range of application is also limited to.Adopt finished product to make up, cost is higher, and this combination product can only use alternating current.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of electromagnetic switching device and door lock integrated, and volume is little, and cost is low, makes easyly, exchanges, all spendable Electromagnetic lock of direct current.

The purpose of this utility model can reach by following measure:

A kind of Electromagnetic lock, comprise lock body, dead bolt, pintle hook lock, its special character is, described lock body is an Electromagnetic lock, described dead bolt is the conducting magnet core of being located in the Electromagnetic lock, dead bolt is provided with and can makes dead bolt retainer spring that resets and the location jump ring that limits the dead bolt shift length, and the dead bolt afterbody is located in the electromagnetic coil, and the Electromagnetic lock rear end is provided with magnetic conductive cover; Pintle hook lock is provided with the groove that can cooperate with the dead bolt front end.

Accompanying drawing is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to accompanying drawing, dead bolt 2 of the present utility model is a conducting magnet core, be located in the Electromagnetic lock 3, and can move forward and backward within it, outside the extended Electromagnetic lock 3 of dead bolt 2 front ends, enter in the groove of pintle hook lock 1, dead bolt 2 is provided with back-moving spring 4 and location jump ring 5, back-moving spring 4 one ends peak on the dead bolt 2, and the other end is fixed on the Electromagnetic lock 3, and location jump ring 5 is fixed on the dead bolt bar of dead bolt 2.Location jump ring 5 can be adjusted the distance that dead bolt 2 moves.Dead bolt 2 afterbodys are located in the electromagnetic coil 6, and electromagnetic coil 6 can join with power supply through prap 7, the prap 7 outer sheaths 8 that are provided with.Electromagnetic lock 3 rear ends are magnetic conductive cover 9.After control system is sent signal, power connection, electromagnetic coil 6 gets electric, and its magnetic field suction dead bolt 2 moves, and dead bolt 2 withdraws from from pintle hook lock 1, and lock promptly is opened; After the outage, under the effect of back-moving spring 4, dead bolt 2 is headed in the pintle hook lock 1, and tapered end is closed.Electromagnetic lock of the present utility model, dead bolt, magnetic conductive cover etc. can adopt industrial soft iron or other permeability magnetic material.

The utility model compared with prior art has following advantage:

1, electromagnetic switching device and door lock are integrated, and compact conformation, volume only have 2/3 of former combined type product, and can be designed to the different profiles being convenient to install.

2, the manufacturing is easy, with low cost.

3, can be connected with different control systems, also can be connected with mechanical switch, widely applicable.

4, power supply can adopt interchange, direct current or DC-AC two-use power supply.

Claims

1, a kind of Electromagnetic lock, comprise lock body, dead bolt, pintle hook lock, it is characterized in that: described lock body is an Electromagnetic lock, described dead bolt is the conducting magnet core of being located in the Electromagnetic lock, dead bolt is provided with and can makes dead bolt retainer spring that resets and the location jump ring that limits the dead bolt shift length, the dead bolt afterbody is located in the electromagnetic coil, and the Electromagnetic lock rear end is provided with magnetic conductive cover; Pintle hook lock is provided with the groove that can cooperate with the dead bolt front end.
