Abstract
The utility model relates to an irregular sectional material double-cavity co-extrusion adhesive tape and belongs to the technical field of building doors and windows. The adhesive tape and a sectional material are connected tightly, and the irregular sectional material double-cavity co-extrusion adhesive tape is good in stability, windproof, waterproof and dustproof. The technical scheme is that the irregular sectional material double-cavity co-extrusion adhesive tape comprises a rubber strip body, and the section of the rubber strip body is mainly formed by an O-shaped structure, a first vertical edge, a second vertical edge and a base. The O-shaped structure, the first vertical edge and the second vertical edge are fixed on the base, the second vertical edge is located between the O-shaped structure and the first vertical edge, and the base is further provided with a first protrusion and a second protrusion which are used for being clamped in a sealing groove. The irregular sectional material double-cavity co-extrusion adhesive tape is windproof, waterproof, dustproof and good in stability and is widely used for plastic steel doors and windows.
Description
Technical field
The utility model relates to a kind of profile shapes two-chamber coextrusion rubber strip, belongs to building doors and windows technical field.
Background technology
At present, plastics-steel shapes for door and window weather strip makes to be comprised of two one high and one low flat adhesive tape, is distributed in the sealing notch both sides of plastics-steel shapes for door and window.This sealing joint strip is connected not tight with section bar, steadiness is poor, causes adhesive tape easily to come off, and this sealing joint strip of while is windproof, waterproof and dustproof poor performance, and sealing is poor, and easily distortion.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of adhesive tape and has been connected with section bar closely, and steadiness is good, can be windproof, the profile shapes two-chamber coextrusion rubber strip of waterproof and dustproof.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: profile shapes two-chamber coextrusion rubber strip, comprise: rubber strip body, the cross section of described rubber strip body mainly consists of O shape structure, the first vertical edge, the second vertical edge and base, described O shape structure, the first vertical edge and the second vertical edge are all fixed on base, the second vertical edge, between O shape structure and the first vertical edge, is also provided with on described base for being installed on the projection of first in seal groove and the second projection.
Described the first vertical edge is obliquely installed.
The free end of described the second vertical edge is fixed on the first vertical edge.
The beneficial effect that the utility model compared with prior art had is: in the utility model, adopt the first annular seal space of O type structure formation and the common crush seal of the second annular seal space that the first vertical edge, the second vertical edge are connected to form, good airproof performance, there is good windproof, waterproof and dustproof performance simultaneously, not yielding; And O type structure, the first vertical edge and the second vertical edge are fixed together, and be installed in seal groove by the first projection and the second projection, adhesive tape is connected with section bar closely, and steadiness is good, difficult drop-off.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is rubber strip body, 2 is O shape structure, and 3 is the first vertical edge, and 4 is the second vertical edge, and 5 is base, and 6 is the first projection, and 7 is the second projection, and 8 is seal groove, and 9 is section bar.
The specific embodiment
As shown in Figure 1, profile shapes two-chamber coextrusion rubber strip, comprise: rubber strip body 1, it is characterized in that: the cross section of described rubber strip body 1 mainly consists of O shape structure 2, the first vertical edge 3, the second vertical edge 4 and base 5, described O shape structure 2, the first vertical edge 3 and the second vertical edge 4 are all fixed on base 5, the second vertical edge 4, between O shape structure 2 and the first vertical edge 3, is also provided with on described base 5 for being installed on the projection of first in seal groove the 6 and second projection 7.
Described the first vertical edge 3 is obliquely installed.
The free end of described the second vertical edge 4 is fixed on the first vertical edge 3.
In the utility model, O shape structure 2 forms the first annular seal space, the first vertical edge 3 and the second vertical edge 4 are joined together to form the second annular seal space, during use, the common extruding of the first annular seal space and the second annular seal space seals, good airproof performance, there is good windproof, waterproof and dustproof performance simultaneously, not yielding, O shape structure 2, the first vertical edge 3 and the second vertical edge 4 are all fixed on base 5 simultaneously, on base 5, be provided with for being installed on the projection of first in seal groove the 6 and second projection 7, rubber strip body 1 and section bar are fastenedly connected, steadiness is good, difficult drop-off.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skills; various variations can also be under the prerequisite that does not depart from the utility model aim, made obtaining, also protection domain of the present utility model should be considered as.
