Abstract

The utility model provides an electromagnetic lock which comprises a lock case, a magnetism assembly, a spring and a spring bolt,wherein after being electrified, the magnetism assembly attracts the spring bolt by magnetic force, so that the spring bolt retreats from a spring bolt hole and unlocking is finished; after the magnetism assembly losses electricity, the compressed spring rebounds, so that the spring bolt is pressed into the spring bolt hole and locking is finished. The electromagnetic lock further comprises a manual unlocking device. A stay cord is pulled, a plectrum pushes a driving lever to pull the spring bolt out of the spring bolt hole, so that manual unlocking is finished. According to the electromagnetic lock, electric roller shutter remote control door opening/unlocking/door closing/padlock can be simultaneously completed, and the function of manual unlocking under the condition of emergency is realized. The electromagnetic lock has the advantages that the structure is simple, the installation is convenient, the cost is low, and the like.The inventive purposes are achieved by additionally arranged a module on the basis of existing electric doors.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the electromagnetic lock critical piece comprises lock housing 1, magnetic force assembly 2, spring 3 and dead bolt 4 to concrete structure of the present utility model.Magnetic force assembly 2 inside are provided with the cavity that can hold spring 3 and dead bolt 4; Dead bolt is the cylinder with boss, within an end pocketed springs, stretches into the cavity of magnetic force assembly, and the other end stretches out from the perforate of lock housing bottom; Described spring one end is positioned at the top of magnetic force assembly cavity, is sleeved on dead bolt, and the other end is placed on the boss of dead bolt, and the top of magnetic force assembly internal cavities and the boss of dead bolt block spring; The lock housing of an electromagnetic lock end relative with the magnetic force assembly is fixedly mounted on the rolling-gate door track 14 inboard places of lower end door, with the dead bolt correspondence position, the dead bolt hole that allows dead bolt to pass through is set on door track.When opening electric rolling door, corresponding control circuit is also given described magnetic force assembly energising, and the magnetic attraction dead bolt that energising produces exits dead bolt hole and completes and unblank; After while closing rolling-gate, rolling-gate put in place, the recoil of spring compressed after system cut-off magnetic force assembly dead electricity headed into dead bolt hole by dead bolt and completes and lock.

As shown in Figure 1, Figure 2 and Figure 3, the noise when reducing work, arrange the vent 12 of up/down perforation in described dead bolt inside; Dead bolt waist cover has nylon cylinder sleeve 5, and the nylon cylinder sleeve vertically arranges opening; Driving lever 6 is set on dead bolt, and described driving lever 6 stretches out and can in described opening, slide up and down from the opening of nylon cylinder sleeve 5, can guarantee that like this dead bolt be movably arranged in electromagnetic lock moves along rectilinear direction, reduces the generation that gets loose and be offset.
