Abstract

The invention relates to an automatic security door with a door leaf weight balance structure, and relates to the field of automatic security doors. On the basis of an original security door, a rotaryshaft and a supporting arm are additionally arranged, two ends of the supporting arm are separately connected with the rotary shaft and a door leaf, pull force generated during the rotation of the supporting arm forms counterclockwise torque which is equal to clockwise torque generated by the weight center of the door leaf and counteracts each other so as to ensure that the door leaf is not deflected, and the balance state of an open fan composed of a moving column and the door leaf in the process of opening and closing is ensured; and the structure enables the external driving force needed when the door leaf moves to the left and right to be less, the structure is simpler, the manufacturing, installation, debugging and maintenance are more convenient, and the cost is lower.

Description

technical field [0001] The invention relates to the field of automatic anti-theft doors, in particular to an automatic anti-theft door with a door leaf weight balance structure. Background technique [0002] The existing automatic opening anti-theft door generally installs a hanger on the left upper part of the door leaf. The hanger drives the door leaf to move along the track of the upper door frame to realize the opening and closing of the door leaf. Since the hanger is only installed on one side of the door leaf, it is easy to cause the door leaf The deflection causes the slider connected with the hanger to be stuck due to the great friction between it and the guide rail, so that the door leaf cannot be opened and closed normally. In order to ensure the smooth opening of the door leaf, it is necessary to use a balance structure, such as the invention patent with the publication number 106930643A and the name "A Translating Automatic Opening Anti-theft Door". The body bal...
