Abstract

The utility model relates to an airtight door, which comprises a movable door leaf (1) and a guideway (2) above which an orbit (21) is arranged, wherein the bottom of the movable door leaf (1) is provided with a rubber pad (11), and the top of the movable door leaf (1) is fixed with a hanging frame (3) provided with a pulley (4). The pulley (4) is inserted on the orbit (21) of the guideway (2) to move, the guideway (2) is provided with a groove (22) which is lower than the orbit (21) at the position corresponding to the pulley (4) of the movable door leaf (1) under a closed state, the bottom of the groove (22) is positioned at the inner side of the bottom of the orbit (21), and the groove (22) and the orbit (21) are in smooth transition. Through arranging the groove at the relevant position of the guideway, the rubber pad of the bottom is attached to the ground completely by the utility model when the movable door leaf is closed at a fixing position and the sealing performance of the airtight door is ensured. In the course of opening and closing the movable door leaf, the rubber pad is prevented from contacting the ground thoroughly, the abrasion degree of the rubber pad is reduced and service life is increased.

Description

A kind of air tight door

Technical field

The utility model relates to the automatic door technical field, particularly a kind of air tight door.

Background technology

Automatic-opening various air tight door because of guaranteeing advantages such as indoor relative sealing and health, convenience, has been widely used in the special occasions such as hospital operating room and sterile production workshop.Existing air tight door, generally comprise the twice swing leaf and be positioned at door leaf top and be provided with the frame of guide rail, and the swing leaf top is fixed with the door leaf suspension bracket, suspension bracket is provided with pulley, and this pulley can roll on the guide rail of frame, also is provided with motor and transmission mechanism on frame, the output of transmission mechanism promptly links to each other with suspension bracket, when motor when transmission mechanism drives suspension bracket and rolls on guide rail, swing leaf promptly moves laterally, and removes to one side.The shape of this guide rail generally matches with regard to the shape that is made into bottom pulley, thereby pulley is flatly moved on guide rail.Simultaneously, for strengthening the sealing performance of air tight door, the swing leaf bottom is provided with rubber pad toward contact, but swing leaf needs frequent translation, rubber pad and ground rub again and again, cause the wearing and tearing of rubber pad easily, reduce application life, and cause the rubber pad bottom can not be fully and the ground applying, directly influence the sealing performance of air tight door.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of application life the long and very desirable air tight door of sealing performance at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this air tight door, include swing leaf and be positioned at swing leaf top and be provided with the guide rail of track, the bottom of wherein said swing leaf is provided with rubber pad, its top then is fixed with suspension bracket, this suspension bracket is provided with pulley, this pulley just is embedded on the track of described guide rail and moves, it is characterized in that: the position of described guide rail described pulley under the described swing leaf closure state of correspondence has the groove that is lower than track, and rounding off.

When swing leaf was closed, the one side can be close on the side of doorframe, does not have the slit to guarantee swing leaf both sides and doorframe; strengthen the sealing of air tight door; when swing leaf is closed in translation, need be to the bias internal certain distance, so; the bottom of described guide rail upper groove can be positioned at the inboard of its track bottom; like this, described swing leaf also can be taken advantage of a situation and moves to the inside when being moved downward; when it is closed, be close to doorframe.

And for rubber, its dilatability is limited, for increasing the flexible height of swing leaf bottom rubber pad, when swing leaf is moved downward, can guarantee the complete and ground applying of rubber pad, and described rubber pad can be tabular, and extends to the side direction bending.

Be further enhanced leaktightness performance, the both sides of described swing leaf bottom can be provided with described rubber pad, when swing leaf moves downward like this, the side direction bending extension of the rubber pad of its two bottom sides is all to lateral extension, guaranteed the complete and ground applying in swing leaf bottom, good sealing effect.

Compared with prior art, advantage of the present utility model is: offer groove by the relevant position at guide rail, when swing leaf is moved into place closing, pulley will be on guide rail groove and move downward certain distance, thereby compress the rubber pad of swing leaf bottom, make its complete and ground applying, guaranteed the sealing performance of air tight door, and open the door and during translation when swing leaf, pulley again can be along the rounding off at groove edge and is risen to normal level height, swing leaf will and then upwards promote certain distance and translation, rubber pad is in swing leaf opening and closing process like this, thoroughly avoid coming in contact, reduced its degree of wear greatly, increased application life with ground; And the guide rail upper groove is with respect to the design of original normal orbit do to bias internal, make swing leaf when closing, when moving downward, can be offset to the inside and just in time flush with the side of doorframe, guaranteed and doorframe between do not have the slit, strengthened the sealing of air tight door; Simultaneously, the rubber pad of tabular bends the bottom that is arranged on swing leaf to side direction with extending, has solved the limited difficult problem of rubber pad dilatability like a cork, has guaranteed the sealing performance of air tight door.The utility model is simple in structure, the sealing performance ideal, and outward appearance is neat and artistic, is easy to apply.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structural representation under the swing leaf closed condition.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, this air tight door, include swing leaf 1 and be positioned at swing leaf 1 top and be provided with the guide rail 2 of track 21, wherein the bottom of swing leaf 1 is provided with rubber pad 11, its top then is fixed with suspension bracket 3, this suspension bracket 3 is provided with pulley 4, and this pulley 4 just is embedded on the track 21 of guide rail 2 and moves;

And described guide rail 2 has the groove 22 that is lower than track 21 in the position of corresponding swing leaf 1 closure state lower sheave 4, and the bottom of this groove 22 is positioned at the inboard of its track 21 bottoms, and this groove 22 and track 21 rounding ofves;

Described rubber pad 11 is tabular, and extends to the side direction bending.

When swing leaf 1 is closed, pulley 4 translation on the normal orbit 21 of guide rail 2, suspension bracket 3 then drives swing leaf 1 and moves horizontally by the track of pulley 4, when moving into place, pulley 4 is taken advantage of a situation downwards and upcountry and is moved in the groove 22 on the guide rail 2, and swing leaf 1 also and then downwards and move inward certain distance, like this, fitting fully in the rubber pad 11 and the ground of swing leaf 1 bottom, then fits fully with doorframe 5 in the side of swing leaf 1; Correspondingly, when swing leaf 1 is opened, pulley 4 from the groove 22s of guide rail 2 upwards and move to laterally on the

track

21,1 of swing leaf and then makes progress and moves a certain distance laterally, like this, the rubber pad 11 of swing leaf 1 bottom breaks away from ground, and its side also breaks away from doorframe 5, moves horizontally then.
