Description

Simple Electromagnetic Lock

technical field

The utility model relates to a lock set controlled by an electromagnet, in particular to an electromagnetic lock used on a self-service storage cabinet.

Background technique

In order to save labor costs, self-service lockers are usually found in supermarkets, libraries, bathing places and other public places, which are used to store some carry-on items by themselves. At present, the electromagnetic locks on the self-service storage cabinets all have multiple parts, the structure is relatively complicated, and the volume is also large, so it is difficult to install them in smaller storage cabinets. The Chinese Patent Office published on September 10, 2014, a safe electromagnetic lock with the patent number "201420198786.8", which includes a lock body, a deadbolt, a rotating shaft, an electromagnet and a coil. The mold cavity that the coil is suitable for, the coil is connected to the power supply of the safe, the electromagnet is a columnar structure, the electromagnet is socketed with the coil, and passes through the cavity, and the electromagnet is provided with a return spring, the return spring The other end of the lock is fixed to the main body of the lock, and the lock tongue is connected to the main body of the lock through a rotating shaft. A torsion spring and a limit groove matching the electromagnet are arranged on the lock tongue, and the other end of the torsion spring is fixed to the rotation shaft. . After the electromagnet is unlocked, this electromagnetic lock will also be unlocked by turning the dead bolt with a key, and the structure is also more complicated.

Contents of the invention

The purpose of this utility model is to provide people with an electromagnetic lock with small volume, simple structure, low cost and convenient use for the self-service locker against the above-mentioned defects and deficiencies of the prior art.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the simple electromagnetic lock, which includes a bottom case and an outer cover, an electromagnet is installed on the rear side of the bottom case, and a telescopic armature is provided at the front end of the electromagnet , the front side of the bottom case is provided with a baffle plate, and the front end of the armature is provided with a lock tongue, which is inserted through the baffle plate, and a spring is set on the armature, and when the electromagnet is energized, the lock tongue retracts In the baffle, when the electromagnet is de-energized, the dead bolt stretches out of the baffle under the spring restoring force.

The baffle is formed by bending the bottom shell upwards.

The armature and the electromagnetic lock are integrally processed.

An insert is arranged inside the baffle, and a bolt hole matching the shape of the bolt is opened on the insert.

A snap ring is embedded on the armature, and a washer is arranged between the snap ring and the spring.

Both sides of the outer cover extend outward to form a fixing bar, and a plurality of installation holes are opened on the fixing bar.

The outer cover and the bottom case are fixed by screws.

The utility model is mainly used for self-service storage cabinets. When the electromagnet is energized, the lock tongue retracts into the baffle plate. When the electromagnet is de-energized, the lock tongue extends out of the baffle plate under the action of the spring restoring force, and the lock is directly driven by the electromagnet. The tongue moves, and has the advantages of small volume, simple structure, low cost and convenient use.

detailed description

As shown in Fig. 1, Fig. 2, Fig. 3, the utility model is a kind of simple electromagnetic lock, and it comprises bottom case 8 and outer cover 3, and described outer cover 3 and bottom case 8 are fixed by screw 4. Both sides of the outer cover 3 extend outward to form a fixing bar 3.1, and a plurality of mounting holes 3.2 are opened on the fixing bar 3.1 for installing the electromagnetic lock to the self-service storage cabinet.

An electromagnet 7 is installed on the rear side of the bottom case 8, and a telescopic armature 5 is provided at the front end of the electromagnet 7, and the armature 5 can retract when the electromagnet 7 works. The front side of the bottom case 8 is provided with a baffle 8.1, and the baffle 8.1 is formed by bending the bottom case 8 upward. A lock tongue 1 is provided at the front end of the armature 5. The armature 5 and the electromagnetic lock are integrally processed, and the lock tongue 1 is inserted on the baffle plate 8.1. The armature 5 is covered with a spring 6, the armature 5 is embedded with a clip spring 9, and a washer 10 is arranged between the clip spring 9 and the spring 6, so when the electromagnet 7 is de-energized, the spring 6 The restoring force can push the armature 5 and the dead bolt 1 outwards.

The baffle 8.1 is provided with an insert 2, and the insert 2 is provided with a lock tongue 1 hole matching the shape of the lock tongue 1, and the insert 2 can prevent the lock tongue 1 from shaking.

The utility model is mainly used for self-service lockers. When the electromagnet 7 is energized, the lock tongue 1 retracts into the baffle plate 8.1. When the electromagnet 7 is de-energized, the lock tongue 1 protrudes out of the baffle plate 8.1 under the restoring force of the spring 6. , the bolt 1 is directly driven by the electromagnet 7 to move, which has the advantages of small size, simple structure, low cost and convenient use.
