Technical Field

The invention relates to a door, in particular to an access door arranged on an access to control the passing.

Background

In many stations, airports and other public places, access doors are required to be arranged on the access passages, wherein some doors only allow one-way passage and some doors allow two-way passage. In order to meet the requirement of one-way passing, the existing one-way doors arrange mutually spaced cross bars into comb-shaped door leaves, more than two (generally four) door leaves are arranged on a rotating shaft to rotate in one direction, and then a row of fixed comb-shaped door leaves and the rotating door leaves form intersection to prevent reverse passing, so that air circulation cannot be prevented, the one-way doors do not have a windproof function, the width of a channel is large, the occupation ratio of useless channels (namely the occupied space of the fixed door leaves) is high, a plurality of required rotating door leaves consume a certain space, and other one-way doors have the defect of complex structure; for a two-way door, a windtight door leaf can be used, but in order to always block the passage, more than two door leaves (generally four) are also needed, and the width of the passage needs the width of two door leaves, which is not practical for some occasions where only a narrow passage can be arranged.

Disclosure of Invention

The invention aims to provide a passage door which can always keep a passage blocked when passing in a one-way or two-way mode, has few door leaves, small required passage width, high effective passage occupation ratio and simple and practical structure, and can easily realize the windproof effect.

In order to achieve the purpose, the invention adopts the following technical scheme:

a channel door comprises a channel, wherein a rotating shaft, a first door leaf and a second door leaf are arranged on the channel, the first door leaf or the second door leaf rotates along with the rotating shaft and can translate on the rotating shaft, when the channel is plugged by the first door leaf, the first door leaf rotates along with the rotating shaft but does not translate, and the second door leaf rotates along with the rotating shaft and can translate; when the second door leaf blocks the channel, the second door leaf rotates along with the rotating shaft but does not perform translation, and the first door leaf rotates along with the rotating shaft and can perform translation; the channel is always blocked by the first door leaf or the second door leaf.

Preferably, the rotating shaft is provided with a first vertical seam and a second vertical seam, the first door leaf translates in the first vertical seam, and the second door leaf translates in the second vertical seam; when the first door leaf translates, the second door leaf is positioned on one side of the first vertical seam; when the second door leaf translates, the first door leaf is positioned on one side of the second vertical seam.

Preferably, a first group of auxiliary wheels is arranged on the first vertical seam, and the first door leaf is positioned between the first group of auxiliary wheels; and a second group of auxiliary wheels are arranged on the second vertical seam, and the second door leaf is positioned between the second group of auxiliary wheels.

Preferably, a guide track is arranged at the top and/or the bottom of the channel, a guide member is arranged at the top and/or the bottom of the first door leaf and the second door leaf, and the guide member drives the first door leaf and the second door leaf to move along the guide track and enables the first door leaf and the second door leaf to perform the translational motion.

Preferably, a first gear is arranged on the first vertical seam, a first rack is arranged on the first door leaf, and the first gear drives the first door leaf to move horizontally through the first rack; and a second gear is arranged on the second vertical seam, a second rack is arranged on the second door leaf, and the second gear drives the second door leaf to translate through the second rack.

Preferably, the first rack is located at the top of the first door leaf, a first roller is arranged at the bottom of the first door leaf, the second rack is located at the top of the second door leaf, and a second roller is arranged at the bottom of the second door leaf.

Preferably, the first and second perps are orthogonal.

Preferably, the channel has a first side wall and a second side wall, an inlet and an outlet are formed between the first side wall and the second side wall, the rotating shaft is arranged between the inlet and the outlet and provided with a blocking portion between the rotating shaft and the first side wall, the second side wall has an arc-shaped portion, and when the first door leaf or the second door leaf blocks the channel and rotates, the outer end of the first door leaf or the second door leaf is substantially tangent to the arc-shaped portion.

Preferably, the arc of the arc part is 90 degrees.

Preferably, the rotating shaft is a one-way rotating shaft or a two-way rotating shaft, and the first door leaf and the second door leaf are provided with through parts or are not provided with through parts.

Preferably, the rotating shaft is a unidirectional and bidirectional convertible rotating shaft, and unidirectional and bidirectional conversion is performed through network control or unidirectional and bidirectional conversion is controlled through a manual switch.

Preferably, the guide rails are arc-shaped and located at both sides of the rotating shaft.

According to the technical scheme, the vertical seams allowing the two door leaves to translate are arranged on the rotating shaft, when the first door leaf rotates and blocks the channel, a space is reserved for the second vertical seam of the rotating shaft, the second door leaf can penetrate through the second vertical seam and simultaneously reserve a space of the first vertical seam, and when the second door leaf rotates and blocks the channel, the first door leaf can translate and change positions in the first vertical seam. Because the translational motion can be carried out, the door leaves can pass through the rotating shaft from one side of the rotating shaft and then are positioned at the other side of the rotating shaft, the effect that the difference of the four door leaves is 90 degrees in the past is achieved, the whole process that the door leaves pass through the vertical seams to block the channels is experienced in the process that the door leaves rotate less than half a circle, the rotation of one circle is not needed, and the channel width of nearly one door leaf is saved. Meanwhile, the structure of the passage door allows a single door plate to be used instead of the comb-shaped door leaf, so that the windproof effect can be realized. Compared with other one-way doors in the prior art, the passage door is simple in structure and convenient to popularize.
