Abstract

The utility model is a lower doorframe sealing material. The middle of the utility model is a rectangle vacuum tube 1. The two opposite sides of the rectangle vacuum tube extend outwards to form a concave groove 2. The two upright edges of one side of the concave groove 2 are provided with a film clamping groove 22. The upright edge 21 with the film clamping groove 22 extends inwards to form a L-shaped or reverse L-shaped folding edge 23. The film clamping groove 22 is arranged on the outer side of the folding edge 23. The cross section of the film clamping groove 22 takes a T shape. Obviously, the film clamping groove 22 can be only arranged on one upright edge of the upright edges 21. The upright edge 21 which is on the other side of the concave groove 2 extends in horizontal direction from the upper side of the vacuum tube 1 to form a side groove 3. The cross section of the side groove 3 takes one fourth round arc shape. The utility model has the advantage of good dustproof efficiency.

Description

Student's frame seal profile

Technical field

The utility model relates to a kind of section bar that is used to do student's frame, and especially middle is a blank pipe, and the relative both sides of blank pipe are extended the formation groove laterally, are provided with student's frame seal profile of film holding tank on one or two stile of a described side groove.

Background technology

Existing door, window mostly are aluminium alloy door, window greatly, and they all are to make frame with aluminium alloy extrusions, and then, installation glass or other sheet material form in the middle of framework again.The aluminium alloy door of making in this way, window, though it is beautiful to have outward appearance, long-lived advantage,, its dustproof poor effect.As preventing dust, sometimes people have to the thing of film and so on the slit between other fixtures such as the limit of door or window and wall be sealed, for example, for the lower frame of revolving door and the gap between the ground, generally can be on the lower frame of door, nail on or stick film, to prevent in cold wind or the dust inlet chamber.For the cleaning factory building, especially like this.Chinese patent literature CN2729262 discloses a kind of sash frame section bar of alumium alloy door and window, is a blank pipe in the middle of it, and both sides have groove, and there is the film holding tank one of a side groove or two stile inboards, on the film holding tank film are installed.With the Aluminium alloy window-door that the disclosed section bar of this patent documentation is made, solved sealing, and the problem of dustproof sound insulation of window door preferably.But; because the employed film holding tank of this section bar is square; and be positioned at one or two stile inboards of a side groove; it only only is suitable for window limit static or that move back and forth relatively this section bar, is unsuitable for doing the lower frame of revolving door, because; this lower frame that revolves door is done rotatablely moving back and forth through regular meeting; in the course of time, this film will come off, and prevents dust in this way and also can destroy aluminium alloy door's aesthetic property.

Summary of the invention

The purpose of the present utility model is: provide a kind of student's frame seal profile to society, this section bar not only can be suitable for doing the frame of window, be more suitable for simultaneously in the lower frame of doing revolving door, and also do not damage the overall appearance effect of aluminium alloy door, be particularly suitable for doing the student's frame that purifies factory building.

The technical solution of the utility model is: design a kind of student's frame seal profile, the centre is a blank pipe, the relative both sides of described blank pipe are extended the formation groove laterally, on one or two stile of a described side groove, be provided with the film holding tank, the described stile that is provided with the film holding tank extends L-shaped to the inside or/and the flanging of anti-" L " shape, and described film holding tank is arranged on the described flanging outside.Herein " or/and " implication be: when on having only a stile holding tank being arranged, then described stile extends the flanging of L-shaped or anti-" L " shape to the inside; When being equipped with holding tank on two stiles, then stile extends the flanging of L-shaped and anti-" L " shape to the inside.

The cross section of described film holding tank is " T " font.

A stile of described opposite side groove extends the back in described blank pipe side upper lateral and forms a side channel.

The cross section of described side channel is the quadrant arc.

As to improvement of the present utility model, the utility model also can be designed to, and a kind of student's frame seal profile comprises a blank pipe, and is fluted in a side of described blank pipe, and one or two film holding tank is arranged under the bottom surface of described groove opposite side.

When described film holding tank was one, described film holding tank was arranged in the middle of the downside of bottom surface.

The utility model is owing to adopted the described stile that is provided with the film holding tank to extend the flanging of L-shaped or anti-" L " shape to the inside, be arranged on the described flanging outside at described film holding tank, the film holding tank of She Zhiing like this, be more suitable in the lower frame of making the aluminium alloy door, with described film holding tank Cross-section Design is " T " font, embeds wherein with the film with identical " T " font top, and its anti-dust performance is good, fastness is good, and after film is ground away, also change easily.

The specific embodiment

See also Fig. 1, it is a kind of student's frame seal profile, the centre is a rectangle blank pipe 1, the relative both sides of described rectangle blank pipe 1 are extended formation groove 2 laterally, on two stiles 21 of a described side groove 2, be provided with film holding tank 22, described two stiles 21 that are provided with film holding tank 22 extend the flanging 23 of L-shaped and anti-" L " shape respectively to the inside, certainly, when a stile 21 extends to the inside can L-shaped or anti-" L " shape.Described film holding tank 23 is arranged on described flanging 22 outsides; The cross section of described film holding tank 22 is " T " font, and obviously, described film holding tank 22 also can only be arranged on the stile of described stile 21; A stile 21 at described opposite side groove 2 is to extend the back in described blank pipe 1 side upper lateral to form a side channel 3, and the cross section of described side channel 3 is the quadrant arc.

See also Fig. 2, Fig. 2 is the cross-sectional structure schematic diagram of the another kind of embodiment of the utility model, and it is compared with embodiment illustrated in fig. 1, and its general structure is identical, and different is: there is not side channel 3 in it.

See also Fig. 3, Fig. 3 is the cross-sectional structure schematic diagram of another embodiment of the utility model; It is compared with embodiment illustrated in fig. 1, and its general structure is identical, and different is: it has only a groove 2, and its film holding tank 22 is located immediately on the both sides of non-groove 2 one sides of blank pipe 1, like this, saves the cost of section bar more.

See also Fig. 4, Fig. 4 is the cross-sectional structure schematic diagram of another embodiment of the utility model; It is compared with embodiment illustrated in fig. 3, and its general structure is identical, and different is: its film holding tank 22 is positioned in the middle of the base of non-groove 2 one sides of blank pipe 1, like this, can further save the cost of section bar than section bar shown in Figure 3.

During use, with this lower frame as the aluminium alloys doorframe, film on described film holding tank 22 is embedded, this film has the film head that matches with film holding tank 22 " T " glyph shape, and the film head is inserted in the described film holding tank 22.Like this, just can play and prevent that dust from entering in the purification factory building from the gap between student's edge and the ground.
