Two-leaf rotary automatic door with circular-arc door leaf capable of intelligently retracting

Abstract

The invention discloses a two-leaf rotary automatic door with a circular-arc door leaf capable of intelligently retracting. The two-leaf rotary automatic door comprises a fixed circular-arc curved wall, a rotary fan and a driving system driving the rotary fan to rotate. The rotary fan comprises a main body, the circular-arc door leaf arranged on the main body and separated from the main body and a movable fan front stile arranged in the manner of operating ahead of the circular-arc door leaf. The driving system comprises a main driving system driving the rotary fan to perform circular motion, a door leaf driving system driving the circular-arc door leaf to perform smooth movement and a signal detection system in electric connection with the main driving system. The main driving system is further in electric connection with the door-leaf driving system. The two-leaf rotary automatic door with the circular-arc door leaf capable of intelligently retracting has following beneficial effects: by virtue of the separating design, the main body and the signal detection system of the rotary fan can set up a buffer mechanism in a hazardous region of the rotary automatic door in order to offset impact of the rotary automatic door upon a human body; therefore, a user cannot get nipped or collided; and a conventional two-leaf rotary automatic door does not have any greater potential safety hazard.

Description

technical field [0001] The invention relates to a revolving automatic door, in particular to a two-wing revolving automatic door with arc-shaped door wings that can retract intelligently. Pinch or bruise. Background technique [0002] Such as figure 1 and figure 2 As shown, the main structure of most traditional two-wing revolving automatic doors on the market is composed of a rotating moving fan 100, a fixed arc curved wall 200, and a transmission system (including a mechanical system and an electrical system). The rotary moving fan 100 is mainly composed of arc door wings, a display box (optional), a smooth automatic door in the middle (optional) and other parts, which are connected and fixed together. Among them, the vertical stile at the front of the arc door wing is the movable sill 300; facing the entrance and exit of the revolving automatic door, the column on the right side of the fixed arc curved wall 200 is the door right column 400, and the dangerous area is t...

AI Technical Summary

Problems solved by technology

Since the rotating fan 100 is composed of an exhibition box and an intermediate door, the weight of the door body is heavy, and the transmission system cannot stop the rotating fan 100 immediately when it hits or pinches a person.

Therefore, the safety of the traditional two-wing revolving automatic door is not high, and there is a great potential safety hazard, which may cause fatal danger to users, especially vulnerable groups such as children and the elderly at any time.
