A semicircular ring 40 is arranged on the door frame, and a door opening contact 41, a door closing contact 42 and a door closing contact 43 are arranged on the semicircular ring; the door shaft is provided with a rotating part 22, and the rotating part is provided with a movable contact which can be contacted with a door opening contact, a door closing contact and a door closing contact.
The moving contact is connected with the positive pole of the power supply, and a first resistor 51 is arranged between the moving contact and the power supply.
The door opening contact is connected with a first circuit, the first circuit is connected with the motor, the door opening contact is in contact with the movable contact, and the power supply provides reverse current for the motor.
The door closing contact is connected with a second circuit, the second circuit is connected with the motor, the door closing contact is in contact with the movable contact, and the power supply provides forward weak current for the motor.
The door closing contact is connected with a third circuit, the third circuit is connected with the motor, the door closing contact is in contact with the movable contact, and the power supply provides positive direction strong current for the motor.
The first circuit, second circuit, third circuit, and power source may be mounted on the door frame 10, or may be mounted in a housing that is mounted on the door frame. The motor is installed on the top of door frame, and the motor shaft is connected with the door shaft.
Referring to fig. 2 and 4, when the worker opens the door, for example, the angle between the door and the door frame reaches 60 degrees, the movable contact contacts the door opening contact 41, the power supply supplies reverse current to the motor 30, the motor rotates in reverse, the motor drives the door shaft 21 to rotate in reverse, the door shaft drives the door 20 to rotate in reverse, and the door continues to open until the door opening contact is separated from the movable contact.
When the worker closes the door, for example, the angle between the door and the door frame is less than 60 degrees, the door closing contact 42 contacts with the movable contact, the power supply supplies a forward weak current to the motor, the motor 30 drives the door shaft 21 to rotate forward, and the door 20 is gradually closed until the movable contact is separated from the door closing contact and contacts with the door closing contact 43.
When the movable contact contacts the closing contact 43, the power supply provides positive strong current to the motor 30, and the motor drives the door shaft 21 to rotate in the positive direction, so that the door is closed powerfully, and the door is closed completely.
During the process of opening the door by a worker, the movable contact will first pass through the door closing contact 43, then pass through the door closing contact 42, and then contact the door opening contact 41. Because the motor obtains the heavy current and drives the door to rotate with strength when the movable contact contacts with closing the door contact, therefore, in order to facilitate the workman to open the door, until the movable contact contacts with opening the door contact, the invention sets up a third switch, this third switch is connected in series with the positive pole of the power directly, this third switch sets up on the door handle. The door handle rotates, the lock head of the door lock retracts into the door, the lock head is separated from the lock hole on the door frame, and the door can be opened; the workman releases the door handle, and the tapered end resets under the effect of spring, stretches out the edge of door, can cooperate the keyhole of going into on the door frame, pins the door. The third switch may comprise a movable contact connected to the handle, a stationary contact mounted on the door, the handle being rotated such that the movable contact is disengaged from the stationary contact, the power source being disconnected from all of the circuits and the motor being inoperative; after the handle is released by a worker, the handle is automatically reset, the movable contact is in contact with the fixed contact, the power supply can supply power to the circuit, and the motor can work. Thus, the worker rotates the handle to open the door to 60 degrees, releases the handle, and at this time, the door opening contact 41 contacts the movable contact, and the door continues to be opened by the driving of the motor.
If the third switch is not designed, the worker may open the door by force until the door opening contact 41 comes into contact with the movable contact.
When the movable contact contacts the door opening contact 41 or the movable contact contacts the door closing contact 42, the motor can drive the door 20 to automatically open or close, and at the moment, a worker applies acting force to the door to overcome the acting force of the motor driving the door so as to enable the door to rotate according to the intention of the worker.
The main functions of the closing contact 43 are: the telescopic lock head on the door may not retract into the door when the door hits the door frame, so that the door cannot be completely matched in the door frame; therefore, when the door closing contact is in contact with the movable contact, the power supply supplies strong current or large current to the motor, the door is driven to rotate powerfully, the spring elasticity in contact with the lock head is overcome, and the lock head is retracted into the door, so that the door can be completely closed.
