Automatic door derail-preventing rail

Abstract

The invention discloses an automatic door derail-preventing rail. The automatic door derail-preventing rail comprises an upper rail, a lower rail and a storage frame. The upper rail and the storage frame are fixedly connected through rivets, and the lower rail and the storage frame are fixedly connected through rivets. A lengthened protective plate is connected with the lower end face of the upperrail in a riveting mode, and first channel steel and second channel steel are welded inside the storage frame in sequence from top to bottom. According to the automatic door derail-preventing rail, due to the fact that a falling-preventing arc-shaped face, auxiliary rails and steel tooth grooves are arranged and mutually embedded, the area of contact between the falling-preventing arc-shaped faceand an inner groove of a sliding block is increased through the arc-shaped face, widened chamfers prevent the sliding block from being inclined, the chamfers cooperate with protrusions of the slidingblock to enable the sliding block to move in sliding grooves, and the phenomenon that the position of the sliding block on a guide rail deviates is avoided on the premise that the movement speed is not affected. Due to the fact that the steel tooth grooves and springs are arranged, the purpose of fixing is achieved, the shock in the contact process is reduced, and the automatic door derail-preventing rail is firmer, is suitable for different working conditions and has the better application prospect.

Description

technical field [0001] The invention relates to the field of automatic doors, in particular to an anti-derailing track for automatic doors. Background technique [0002] Automatic door refers to the control unit that recognizes the action of people approaching the door as the door opening signal, opens the door through the drive system, automatically closes the door after the person leaves, and realizes the control system for the process of opening and closing. Automatic doors and non-automatic doors The door moves in the same way, and the movement of the rollers or sliders in the track drives the displacement of the main body of the door; the existing automatic door track has certain disadvantages in use, and it is easy to cause the slider to slide after a long time of use or after being subjected to external collisions. It breaks away from the guide rail and causes jamming. At the same time, when the automatic door is received in the frame, there will be a friction or coll...

[0002] Automatic door refers to the control unit that recognizes the action of people approaching the door as the door opening signal, opens the door through the drive system, automatically closes the door after the person leaves, and realizes the control system for the process of opening and closing. Automatic doors and non-automatic doors The door moves in the same way, and the movement of the rollers or sliders in the track drives the displacement of the main body of the door; the existing automatic door track has certain disadvantages in use, and it is easy to cause the slider to slide after a long time of use or after being subjected to external collisions. It breaks away from the guide rail and causes jamming. At the same time, when the automatic door is received in the frame, there will be a friction or collision with the frame, which will easily cause damage to both sides and bring certain adverse effects during use. Therefore, We propose an automatic door anti-derailment track
