Abstract
The utility model relates to an electromagnetic lock of a subway door, and belongs to the electromagnetic locks for subway doors. A lock plunger is fixedly connected with a link bar which is hinged with a crank shaft, the crank shaft is hinged with a pull rod which is connected with an electromagnet in a sliding manner, a guide pole rack is fixedly connected with a baseplate which is in rotationalconnection with a latch hook, a torsion spring is in wire-wrap connection of the latch hook, the lock plunger is connected with a guide pole on the guide pole rack in a sliding manner, and the pressure spring is in sleeve joint with the guide pole. The electromagnetic lock has the advantages of novel and simple structure, low cost, reliable operation, safety control, firm and reliable installation, convenient assembly, disassembly and operation, long service life, low noise, good stability, and energy conservation. Special maintenance personnel can perform manual operation on the electromagnetic lock in the case of power cut or power supply failure. The power supplied for triggering the door lock is of impulse characteristic, which consume little electric energy. The utility model has usage temperature ranging from 50 DEG C to 90 DEG C, relatively extensive scope, and excellent heat resistance and cold resistance.
Description
Technical field
The utility model belongs to a kind of underground automobile door lock.
Technical background
The underground automobile door electromagnetic lock is the important control assemblies of car door such as subway, light rail, bullet train, directly has influence on the safety of the operation and the person.The control of door is current a multiple mode, as the control of S type, vertical latch control etc.The control of S type requires the installation accuracy height, and volume is big.Shortcomings such as the vertical mortise lock lock pin life-span is short, noise is big even can not use.
Summary of the invention
The utility model provides a kind of underground automobile door electromagnetic lock, requires the installation accuracy height to solve the control that present door lock exists, big, the vertical problem that the mortise lock lock pin life-span is short, noise is big of volume.The technical scheme that the utility model is taked is: locking bolt is fixedlyed connected with link rod, link rod and crank are hinged, crank and pull bar are hinged, pull bar and electromagnet are slidingly connected, the guide pillar frame is fixedlyed connected with substrate, and latch hook is connected with substrate rotating, torque spring and latch hook solderless wrapped connection, guide pillar on locking bolt and the guide pillar frame is slidingly connected, compression spring and guide pillar socket.
At closing time, under the power effect of door push rod A, promote two latch hooks and rotate relatively, at this moment locking bolt blocks latch hook in the compression spring effect falls into the latch hook card.As run into rocking of door, and impact, various fortuitous events such as vibrations, because locking bolt can not produce under the effect of compression spring power to top offset, latch hook just can not produce rotation, door is firmly pinned.
When opening the door, the electromagnet energising produces electromagnetic force, and the pulling pull bar drives the crank rotation, and the pulling link rod makes and moves away stuck position on the locking bolt, and the push rod of door is out of hand, and door just can be opened.
The utility model advantage is a novel structure, simple, and cost is low, and underground automobile door electromagnetic lock reliable operation is guaranteed safety, and is solid and reliable, and charge and discharge operations is convenient.But specialized maintenance personnel manual operation in the time of maybe can't powering has a power failure.Life-span is long, noise is little, good stability.Save the energy.The energising that this door lock is opened belongs to pulse character, and consumed power seldom.Serviceability temperature-50 ℃～90 ℃, scope is wider, has good heat resistance and cold tolerance.
