One-way door with planar door leaves

Abstract

The invention provides a one-way door with plane door leaves and relates to a plate-shaped one-way revolving door capable of being opened in the positive direction and being closed in the reverse direction. The one-way door mainly solves that problem that the gap between the secondary door and the main door of the known plate-shaped one-way door cannot completely block reverse walking of pedestrian and the problems that one end of a folding type secondary door is directly fixed on a connecting rod, a crank connecting rod and a folding door are hinged unstably, the folding secondary door has great inertia during operation, and vibration and noise cannot be overcome. The one-way door comprises three main doors and a secondary door, wherein the three main doors are fixed on a main shaft; the secondary door is connected with the main shaft through a crank connecting rod mechanism; the top of the main shaft is connected with a driving gear of a speed reducer through a key. The one-way door is characterized in that an output shaft of the speed reducer is connected with a pulley through the crank connecting rod mechanism; the pulley is mounted on a rail at the upper end of a door body; the lower part of the pulley is connected with an arc-shaped secondary door edge of the secondary door; the other end of the secondary door is hinged with a secondary door winding drum; a torsional spring is fixed at the end part of the secondary door winding drum; the other end of the torsional spring is fixed on a torsional spring fixing shaft; the upper end of the pulley is connected with a balance belt wheel through a balance belt; the balance belt wheel is fixedly connected to a wheel shaft; one end of the wheel shaft is fixedly connected to the door body through the a balance torsional spring. In the rotating process of the main doors, one main door and the secondary door are contacted all the time and maintain a small gap, so pedestrian only can walk in one way. The one-way door is reasonable and compact in structure, and has a good effect and operates stably through repeated tests.

Description

technical field [0001] The invention relates to a one-way door, in particular to a plate-shaped one-way revolving door with one-way passage and reverse closure. Background technique [0002] There are many kinds of known one-way doors, which are divided into half-height and full-height according to their heights. Half-height one-way doors are a symbolic blocking facility and are used in places where general safety requirements are not high. The full-height one-way door has a complete door frame and is used in more important places. Pedestrians cannot pass in the opposite direction anyway. However, in order to achieve the purpose of continuous one-way traffic in the traditional full-height one-way door, a comb-like fixed comb is provided on one side of the door, and the movable revolving door leaf must also be made into a comb-like shape to bypass the fixed comb. In other words, it is like a comb, using fixed comb teeth to block reverse pedestrians from the door, there are s...

Problems solved by technology

However, in order to achieve the purpose of continuous one-way traffic in the traditional full-height one-way door, a comb-shaped fixed comb is provided on one side of the door, and the movable revolving door leaf must also be made into a comb-like shape to bypass the fixed comb. In other words, like a comb, using fixed comb teeth to block reverse pedestrians from the door, there are still several problems: one is that people on both sides of the inside and outside cooperate with each other, and items can be passed through the gap between the comb teeth; , can not prevent air circulation, so that the northern heating and southern air conditioning efficiency is reduced; the third is the shape of the crisscross, affecting the appearance

[0003] The applicant applied for a plate-shaped one-way door with the application number 2010221686. Although the above-mentioned problems can be solved, there are the following deficiencies: 1. Since the auxiliary door adopts a straight door edge, it is impossible to keep the distance between the main door and the auxiliary door. 2. Since the auxiliary door adopts a folding door, one end is fixed on the door body, and the other end is directly fixed on the connecting rod. The function of one-way traffic cannot be realized; 3. The inertia of the folding auxiliary door is large during operation, and the vibration and noise at the left and right dead points cannot be overcome; 4. When someone deliberately pushes the main door, the speed will be out of control, resulting in damage to the moving components; 5. The running resistance of the folding auxiliary door is quite different in different positions, so it cannot run at a uniform speed
