Description

Electromagnetic lock shaft positioning locking structure

The present invention provides a shaft positioning and locking structure for an electromagnetic lock, in particular, a base of the base body is provided with a lock and a solenoid valve, and the solenoid valve has a body and an actuating assembly, and the movable seat is coupled to the body. The movable seat is provided with an adjusting component at the positioning hole of the base for switching to adjust the power-on unlocking or the power-on locking state.

According to the electromagnetic lock, it is mostly used for the control of the entrance or exit of a building or different compartments. Since the electromagnetic lock is an electromagnetic actuating device capable of converting electric power into mechanical force, and the electromagnetic actuating device is driven by electric power to the motor or the electromagnetic valve, The door can be locked or opened by energizing or de-energizing the drive to push the latch.

Furthermore, the electromagnetic lock can be roughly divided into two types, the first one being a power-off lock door, that is, the lock body is in a state of being locked when the lock body is not energized or powered off, and can be controlled by an external control system (such as a credit card machine, After the card body is energized, the internal electromagnetic actuating device of the lock body is activated to release the latch to achieve the state of opening the door; and the second type is to open the door when the power is turned off, and the door is normally locked. The lower lock body is continuously energized. Only when the external control system powers off the lock body, the electromagnetic actuating device will start to open the door, which can avoid the occurrence of sudden power failures (such as power outages, fires, etc.) due to power failure. The evacuation or escape route caused by the lock door is blocked, even in the case of critical user safety, to ensure the safety of the overall use.

However, the conventional electromagnetic lock system includes a housing, a U-shaped latch and a solenoid device fixed on the back plate, wherein the solenoid device includes a movable rod located in the solenoid for active displacement and is fixed to the movable a stopper at one end of the rod, and a plurality of screw holes are arranged on the back plate, and the housing is provided with a long slot hole and two screw holes provided at the front and the rear, and the long slot hole is fixedly locked on the back board. The adjusting screw in the screw hole of the block, and one of the screw holes in the housing is provided with a positioning screw locked in the screw hole of the back plate away from the block, the positioning screw can be locked close to The screw hole in the right or center of the housing allows the solenoid device to be driven to abut the U-shaped latch position to prevent it from rotating to open the door when energized or de-energized.

However, when the electromagnetic lock switching mode is used, the operator needs to loosen the adjusting screw first, then loosen the positioning screw, and push the adjusting screw to move the back plate to make the solenoid device traverse a distance position, and then the positioning can be performed. The screw is locked in another screw hole to complete the adjustment and positioning. The secondary locking method of the positioning screw is not only complicated and inconvenient, but also the positioning screw is not easy to be aligned after the adjusting screw moves the back plate. Another screw hole; in addition, the solenoid device is fixed at one end of the movable rod to have two protruding portions, and two protruding portions are provided on the U-shaped bolt, when the blocking block and the U-shaped latch When the protruding portions are opposite, the U-shaped latch can not be rotated to lock the door. However, due to the high requirement of the protruding portion of the stopper, the overall structure of the stopper is inconvenient and difficult to manufacture, and the stopper and the block are The movable rod is not stable in the overall structure of the structure. If the stopper is subjected to the U-shaped latch, the movable rod is prone to bending deformation or damage, and it is to be redesigned to effectively solve the problem.

Therefore, the new creators have been using the electromagnetic lock structure in the use of the problems and lack of use, collecting relevant information through multiple assessments and considerations, and using the years of engaging in this industry The R&D experience has been continuously tried and modified, and a new type of shaft positioning and locking structure for such electromagnetic locks has been designed.
