The invention designs and applies a door closer and an intelligent positioning linkage mechanism together, the door closer is a conventional structure and is not described herein, and the end of a connecting rod part of the door closer is hinged with a linkage actuating mechanism 3 in the intelligent positioning linkage mechanism, namely, the action of the linkage actuating mechanism is used for controlling the action of the door closer part in reverse, so that the real-time delayed door closing action of a door leaf is realized, and the specific actuating action process of the intelligent positioning linkage mechanism is carried out as follows:

at first, when one side of the sliding block mechanism at the sliding strip seam is closed, the trigger plate is in contact with the trigger switch, when a person pushes away the door leaf (different persons have different door opening angles, some persons have large door opening angles, and some persons have small door opening angles), the lamplight display feedback module receives a trigger signal, the lamplight display feedback module sends a signal to the time delay controller to start working at the moment, a red light is on, the door closer connecting rod rotates along with the door leaf, and then the door closer connecting rod pulls the sliding block mechanism to act, referring to fig. 1, when the sliding block mechanism moves to a certain position from right to left along the sliding strip seam, the electromagnet is always in an electrified state in the moving process of the sliding block mechanism, the brake wheel is locked by the brake belt, at the moment, the pawl gear wheel can only rotate in one direction, namely, the door can only be opened continuously but not closed, the time delay controller can automatically control the electrified time of the electromagnet, and the electrified time of the electromagnet determines the door opening time, after the delay time is up, the electromagnet is powered off, the door leaf is closed under the action of the door closer, when the door is pushed again, the electromagnet starts to be electrified, and the door leaf can only be pushed open but cannot be closed.

When the door leaf is in the state of opening the door, the red light in the light display feedback module is in the normally-on state, and the green light state is displayed when the door is closed.

The action of closing the door is that the time delay is up, the electromagnet is powered off, the reset spring is reset to enable the steel wire to be loosened, the brake belt loosens the brake wheel, the pawl gear wheel can idle, the linkage steel wire rope can move in the forward and reverse directions, the door closer can push the door leaf to be closed, and the sliding block mechanism continues to return to the initial position.

Due to the arrangement of the infrared sensor on the door frame, when a person continuously passes through the door frame, the electromagnet is triggered to be electrified to lock the brake wheel, and a delay signal is given to the delay controller, so that the delay controller continuously delays, namely, the door leaf can continuously keep the door opening state for more time.

The delay controller is used for controlling two groups of voltages of the electromagnet, one group is instant voltage which is supplied to the electromagnet to electrify the electromagnet, the other group is constant voltage power supply, the instant voltage needs larger suction to lock a brake wheel when the instant voltage is just triggered, and the constant voltage power supply is realized when the door needs to be opened for a long time later, so that the electromagnet can be electrified and attracted to keep electrified for a long time.

In addition, a normally open switch is arranged on the time delay controller and needs to be manually operated to start, and after the normally open switch is started, the electromagnet is always in a constant-voltage power-on state, so that the door leaf is always in an open state and cannot be closed in a retracting manner.

The structure of the invention can also be applied to a fireproof door, and the situation of blocking can not occur when the fireproof door is opened or closed, so that the fireproof door can be opened and stopped at any angle, and the long-time door stopping can be realized.

The invention can realize the actions of opening and stopping immediately, non-returning and delayed closing at any angle of the door by designing a completely new mechanism and matching with the linkage action of the conventional hydraulic door closer, can really realize the positioning of opening and closing the door at any angle, can really realize the intelligent and humanized design of opening and closing the door, can be widely applied to the opening and closing of doors in various types of public places, and has good practical application value and economic value.
