Description

Take sparse translation automatically-controlled door of smoke protection function

Technical Field

The utility model belongs to the technical field of the translation door, concretely relates to take sparse translation automatically-controlled door of smoke protection function.

Background

The concept of automatic sliding door is to be understood as an extension of the concept of automatic door, which is the development and perfection of the function of the door according to the needs of people. Hotels, banks, office buildings, hospitals, shops and the like can see the automatic translation door, and the automatic translation door is often applied to public places. The automatic door is provided with two types of movable door leaves and fixed door leaves, the movable door leaves automatically translate along a track parallel to the plane of the movable door leaves under the normal operation state, and the fixed door leaves are fixed. When emergencies such as fire alarms occur in the interior of a building, the power supply is usually automatically cut off for safety consideration, and people are difficult to escape if the movable door leaf is in a closed state. Therefore, the automatic door is generally provided with a UPS power supply to supply power for one time or more times, so that the movable door leaf is opened in a translational manner again in case of emergency, and people can escape from the automatic door.

When an emergency occurs, the opening size of the automatic door is only the width of the opened movable door leaf, namely half of the width of the whole automatic door opening; in addition, because the UPS belongs to an electronic product, the reliability of the UPS greatly influences safe escape, and if the UPS fails or is not replaced after too long use, the automatic door cannot be opened in an emergency, so that people are difficult to escape. In any state, the automatic sliding door does not accord with the escape specification, the automatic sliding door cannot be opened or is inconvenient to open in emergency, and the escape is facilitated only by the door which can be manually pushed outwards.

Therefore, patent number CN200820147016.5 discloses "automatic door", which adopts a technical scheme including a fixed door leaf, a movable door leaf, an upper guide rail, a bottom rail, a sliding frame, a guide wheel mechanism and a fastener mechanism; one end of the upper end and the lower end of the movable door leaf is pivoted on the sliding frame, and the other end of the movable door leaf is pivoted on the guide wheel mechanism; the upper end and the lower end of the fixed door leaf are respectively pivoted on the upper guide rail and the bottom rail; the movable door leaf is provided with a safety buckle, and the fixed door leaf is provided with a notch. The utility model discloses automatically-controlled door activity door leaf and fixed door leaf all can open under emergency, have high reliability and security, adopt electromagnetic position switch to make activity door leaf can stop the automatic operation at once after being promptly pushed open, can not lead to the fact the crowd of promptly fleing to obstruct or strike the injury. The problem of traditional automatic translation door can't open influence personnel and flee is solved. However, after people escape, the door is still in an open state, smoke can be diffused outwards along with the opened door, people in the escape cannot go back to close the door, and the smoke generated by indoor fire can be diffused outwards to influence people's escape.
