Description

Automatic door opening and closing device

Technical Field

The utility model belongs to the technical field of the door, specific accessory for controlling door automatic switch that says so.

Background

Along with the development of science and technology, current household articles have all become more and more intelligent, improve people's quality of life greatly, like the lock of current entrance door, the mechanical lock of unblanking by the initial key is gradually replaced by the fingerprint, the password or the automatic lock of brushing the face, the vexation of unblanking and forgetting the key has been made things convenient for greatly, nevertheless even unblanking of current these entrance doors is convenient, can still lean on the hand to push away and close to pushing away the door and closing the door, and not set up automatic door opening and closing device, if both hands are holding article when advancing, it is so convenient not just to the switch door, current system board technique is to realizing that door automatic switch's circuit board is made and can be realized completely simultaneously, but because there is not corresponding switch device now, lead to still being unable effect of realizing door leaf automatic switch promptly.

SUMMERY OF THE UTILITY MODEL

In view of the defect that current entrance door exists, the utility model discloses the technical problem that will solve is: the device for controlling the automatic opening and closing of the door is provided, and the device is matched with a circuit board to realize the effect of automatically opening and closing the door.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: an automatic door opening and closing apparatus, comprising:

the power device comprises a speed reducing motor and an electromagnetic clutch, wherein a speed reducing gear box of the speed reducing motor drives a main shaft of the electromagnetic clutch to rotate, a control block is fixed on the main shaft of the electromagnetic clutch, and a stop arm extends from one side of the control block;

the two travel switches are arranged on two sides of the control block, when the resisting arm resists against one travel switch, the door leaf is closed with the door frame, and when the resisting arm resists against the other travel switch, the door leaf is opened to the maximum angle;

one side of the push rod is fixed with the electromagnetic clutch, and the bottom of the other side of the push rod extends to form a sliding shaft;

the door leaf, its top one side of door leaf is opened has a breach, opens the spout that supplies the sliding shaft joint on the bottom surface of breach, and door leaf and door frame closed back, push rod are in the door leaf breach.

This automatic switch door gear is by gear motor's positive and negative rotation, makes electromagnetic clutch can drive the push rod along spout round trip movement, finally makes the push rod pulling or promote the door leaf, makes it open or close.

Further, the notch is a strip-shaped right-angle notch, and the notch end is arranged on one side, opposite to the door frame, of the door leaf. Above-mentioned design not only makes the push rod can hide in the bar right angle breach, and the back is closed to the door leaf simultaneously, can not cause to leave the air vent between door leaf and the door frame yet, causes the door leaf sealed effect not good.

Compared with the prior art, the utility model has the advantages of: the automatic door opening and closing device is matched with the existing plate making technology to achieve the effect of automatic door opening and closing, and the embarrassment that the existing plate making technology is empty and the corresponding door opening and closing specific structure is not available is solved.
