Abstract

The utility model belongs to a door lock, in particular to an electromagnetic lock which uses the electrical signal to open the lock. The electromagnetic lock comprises a lock bolt [8], a self locking column [9], an electromagnet [3], a self locking spring [1], a lock bolt spring [1] and a lock shell [2]. When the lock bolt [8] is inserted into the lock from right, the lock bolt [8] compresses the lock bolt spring [1], pushes the self locking column [9] to move upward, and compress the self locking spring [1]. When the self locking column [9] is inserted into the groove [5] of the lock bolt [8] under the action of the self locking spring [1], the lock is closed. When the electromagnet [3] is power on, the magnetic force pushes the self locking column [9] to move upward and recede out of the groove [5] of the lock bolt [8]. The lock bolt spring [1] pushes the lock bolt [8] out of the lock, and thus the lock opening is realized. The utility model has simple structure, high reliability, difficult failure occurrence and long service life.

Description

Electromagnetic lock

Technical field

The utility model belongs to a kind of door lock, particularly a kind of electromagnetic lock of unblanking with the signal of telecommunication.

Background technology

Electromagnetic lock has remote-controlled, can with characteristics such as various smart cards, the supporting use of fingerprint recognition control system, and locker, strongbox of being widely used in hotel, bank, supermarket, school, outdoor bathing place etc. are located.The deficiency of existing electromagnetic lock commonly used is short a, poor reliability of complex structure, life-span.

The utility model content

The purpose of this utility model is: provide a kind of simple in structure, open and close the quiet electromagnetic lock of lock.

The technical solution of the utility model is: a kind of electromagnetic lock is characterized in that: it comprises:

A cylindric dead bolt, its right-hand member is frustum, and a circle groove is arranged after a while;

One from lock, and it is vertical mutually with dead bolt;

An electromagnet makes from lock after its energising to move up;

A self-locking spring, it promotes to move down from lock;

A latch bolt spring, it is released dead bolt in the lock;

A lock housing, it holds above-mentioned each parts;

In the time of in dead bolt inserts lock to the right, it compress latch bolt spring, and promotion from lock move up, self-locking spring compresses, treat when lock is inserted in the groove on the dead bolt, to finish locking under the self-locking spring effect;

When electromagnet was switched on, its magnetic force promoted to move up and withdraw from groove on the dead bolt from lock, and latch bolt spring is released dead bolt in the lock, realizes unblanking.

The utility model is simple in structure, and the reliability height is difficult for breaking down, and application life is longer.

Description of drawings

Accompanying drawing is the internal construction schematic diagram of the utility model embodiment 1,2.

The specific embodiment

Embodiment 1: referring to accompanying drawing, a kind of electromagnetic lock is characterized in that: it comprises:

A cylindric dead bolt 8, its right-hand member 6 is frustum, and a circle groove 5 is arranged after a while;

One from lock 9, and it is vertical mutually with dead bolt 8;

An electromagnet 3 makes from lock 9 after its energising to move up;

A self-locking spring 1, it promotes to move down from lock 9;

A latch bolt spring 1, it is released dead bolt 8 in the lock;

A lock housing 2, it holds above-mentioned each parts;

In the time of in dead bolt 8 inserts lock to the right, it compress latch bolt spring 1, and promote from lock 9 move up, self-locking spring 1 compresses, treat when lock 9 is inserted in the groove 5 on the dead bolt 8, to finish locking under self-locking spring 1 acts on;

When electromagnet 3 energising, its magnetic force promotes to move up and withdraw from groove 5 on the dead bolt 8 from lock 9, and latch bolt spring 1 is released dead bolt 8 in the lock, realizes unblanking.

Embodiment 2: referring to accompanying drawing, for the intensity of the electromagnetic lock of strengthening embodiment 1, can increase by one be connected on the lock housing 2 from lock fairlead 4.

Claims

1, a kind of electromagnetic lock, it is characterized in that: it comprises:

A cylindric dead bolt [8], its right-hand member [6] is frustum, and a circle groove [5] is arranged after a while;

One from lock [9], and it is vertical mutually with dead bolt [8];

An electromagnet [3] makes from lock [9] after its energising to move up;

A self-locking spring [1], it promotes to move down from lock [9];

A latch bolt spring [1], it is released dead bolt [8] in the lock;

A lock housing [2], it holds above-mentioned each parts;

In the time of in dead bolt [8] inserts lock to the right, it compress latch bolt spring [1], and promote from lock [9] move up, self-locking spring [1] compresses, treat when lock [9] is inserted in the groove [5] on the dead bolt [8], to finish locking under self-locking spring [1] acts on;

When electromagnet [3] was switched on, its magnetic force promoted to move up and withdraw from groove [5] on the dead bolt [8] from lock [9], and latch bolt spring [1] is released dead bolt [8] in the lock, realizes unblanking.

2, according to the electromagnetic lock of claim 1, it is characterized in that: further comprising one be connected on the lock housing [2] from lock fairlead [4].
