Description

An electric door opener with one-way arbitrary position locking

technical field

The invention relates to an electric door opener with one-way locking at any position.

Background technique

The prison door is a high-strength anti-riot door specially designed to adapt to the intelligent construction of the public security department's prevention and monitoring. Prison-specific doors in the prior art usually include a translation door and a horizontal opening door. When a prison needs to arrange prison personnel to go out of the prison, the translation door often needs to open the prison door a little bit for only one or two people to go out at the same time. The prison staff will open all the prison doors. It is necessary to study a one-way locking door opener for prevention, so that the prison door can only move in the direction of closing the door and prohibits opening the door unless it needs to be opened and controlled in an early warning. direction to move.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

As shown in Figures 1 to 5, an electric door opener with one-way arbitrary position locking includes a bottom plate 1, a gear 2, a motor 3, and a one-way locking assembly, and the gear 2, motor 3 and one-way locking The assembly is arranged on the bottom plate 1, the gear 2 is connected with the rack 9 arranged on the door or the door frame (when the electric door opener is arranged on the door, the rack 9 is arranged on the door frame, when the electric door opener is arranged on the door frame When the rack 9 is set on the door), the motor 3 is connected to the gear 2 to drive the gear 2 to rotate and then drive the door to open or close. The one-way locking assembly includes a The base 4, the locking member 5 arranged on the base 4, the electromagnet 6 arranged on the base plate 1, the manual dial 7 arranged on the base plate 1, the locking member 5 includes a locking ring 501, One locking piece 502 and two unlocking pieces 503, the locking ring 501 is rotationally connected with the base 4, the locking piece 502 and the unlocking piece 503 are connected with the locking ring 501, the locking piece 502 Cooperate with the rack 9, the electromagnet 6 cooperates with one of the unlocking pieces 503, and the manual paddle 7 cooperates with the other unlocking piece 503. After the electromagnet 6 and/or the manual paddle 7 moves, the locking piece 502 is released from the rack 9 to release the one-way locking state, and the locking member 5 is provided with a return spring (not shown in the figure) so that after the electromagnet 6 and the manual plectrum 7 are reset simultaneously, the locking The locking piece 502 cooperates with the rack 9 to be in a one-way locking state, and the electromagnet 6 and the motor 3 are electrically connected to the control circuit board 8 , which is arranged on the bottom plate 1 .

As a preferred embodiment, the base 4 is provided with at least one limiting column 401 , and the limiting column 401 is located at the end where the locking piece 502 and/or the unlocking piece 503 is connected to the locking ring 501 . In a further preferred embodiment, the base 4 is provided with a limit column 401, and the limit column 401 is located at the end where the lock plate 502 is connected to the lock ring 501, and the lock plate 502 is connected to the lock ring 501.

working principle:

Take when the electric door opener is set on the door, the rack 9 is set on the door frame as an example (when the electric door opener is set on the door frame, the principle when the rack 9 is set on the door is the same)

1. When the door needs to be opened, input the door opening signal to the door opener, the electromagnet 6 moves to push the unlocking piece 503, and then releases the one-way locking state between the locking piece 502 and the rack 9, the motor 3 works to drive the gear 2 to rotate, and the door opener follows move with the door;

2. When the door reaches the designated position, the electromagnet 6 resets, and the locking plate 502 cooperates with the rack 9 under the action of the reset spring, that is, the one-way locking state. At this time, the door can move in the direction of closing. It cannot move in the direction of the big pocket to achieve one-way locking;

3. When the door needs to be closed, input the door closing signal to the door opener, the electromagnet 6 does not act, and the motor 3 rotates in reverse to drive the gear 2 to rotate in reverse, and the door can be closed.

When running into an emergency, such as a fire and power failure, you can use the key to turn the manual paddle 7 to release the one-way locking state, and then you can open the door with your bare hands; the key hole is symmetrically arranged on the round hole 701 The inner limit block 702 is formed, and a key or a flat object can be used to rotate the manual plectrum 7 at will, so as to prevent the panic from finding the key and not opening the door in case of emergency, causing serious consequences.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the implementation and protection scope of the present invention. For those skilled in the art, they should be able to realize that all equivalents made by using the description and illustrations of the present invention The solutions obtained by replacement and obvious changes shall all be included in the protection scope of the present invention.
