Description

Electromechanical locks

The utility model relates to field of lockset, refers in particular to the electromechanical locks of opening with motor.

After the nineties in last century, building conversational system appearred in China, also occur with the matched electric control door lock of building conversational system thereupon.The electric control lock electricity consumption is opened, and its principle is to utilize coil electricity to produce magnetic field to make the lock core displacement, discharges and threads off, and makes the dead bolt return again, and the withdrawal lock housing is opened the gate.The electric control lock major defect is: noise is too big at closing time, has influenced people's normal life.Causing the excessive main cause of noise is dropout pressure too big (about seven kilograms), and the force rate of usefulness is bigger at closing time so utilize door closer, sends bigger sound when resilient tongue and doorframe are collided.

At the end of the nineties in last century, people require to solve the noise puzzlement that electric control lock is closed the door and brought, and have adopted the magnetic force lock.The operating principle of magnetic force lock is: main lock body is by coil and silicon steel sheet combination, and the energising back produces high-intensity magnetic field, causes closely adhesive of main lock body and suction disc (pure iron), plays closing function.Magnetic force is locked in China some areas and uses after 1 year, and it is found that it has many defectives: (1) keyed end compressive resistance is lower than 600 kilograms (Ministry of Public Security stipulates more than 600 kilograms); (2) have a power failure or during electric being out of order door lock just be in opening, dangerous; (3) because of switching on for a long time, power consumption is big; (4) manufacturing cost height.

For above-mentioned reasons, two locks are not optimal supporting door locks in the building conversational system more than.

For solving above-mentioned two defectives that are latched in, the utility model provides a kind of electromechanical locks, has kept on the basis of former electric control lock advantage to have solved noise problem, makes it become relatively more perfect, the desirable supporting lock of building system.
