Abstract
The utility model discloses a kind of door and window sealing strip, described door and window sealing strip comprises smooth bottom, the left end top of this bottom is provided with the arc sealing of the hanging shape extending to upper right side, simultaneously, the upper surface of this bottom is provided with the raised line of at least 1 section semicircular in shape, and this raised line has hollow cavity, and has air-vent on this raised line, and this doors and windows sealing strip adoption rubber-plastics material is one-body molded.The utility model has the advantages that: sealing effectiveness is better, application life is longer.
Description
Technical field
The present invention relates to weather strip technical field, especially relate to a kind of door and window sealing strip.
Background technology
Door and window sealing strip adopts rubber-plastics material to be prepared as solid stripe or hollow strip more.Its defect is: sealing effectiveness is poor, is easy to form distortion tired.
Summary of the invention
The object of this invention is to provide a kind of door and window sealing strip, it has good sealing effectiveness, and application life longer feature.
The technical solution adopted in the present invention is: door and window sealing strip, described door and window sealing strip comprises smooth bottom, the left end top of this bottom is provided with the arc sealing of the hanging shape extending to upper right side, simultaneously, the upper surface of this bottom is provided with the raised line of at least 1 section semicircular in shape, and this raised line has hollow cavity, and has air-vent on this raised line, and this doors and windows sealing strip adoption rubber-plastics material is one-body molded.
A kind of preparation in described doors and windows sealing strip adoption EPDM, CR, EVA, SBR, NBR.
The side of described bottom is provided with draw-in groove.
The advantage that the present invention has is: sealing effectiveness is better, and application life is longer.The unsettled sealing of doors and windows sealing strip adoption of the present invention, makes the rigidity of sealing portion at the beginning of extruding minimum, and along with the carrying out of pushing, its rigidity has very big lifting, in conjunction with the support giving with raised line, make the sealing effectiveness of sealing bar fabulous, be particularly useful for the sealing of door and window.Meanwhile, under the support of raised line, the root of sealing portion is unlikely to bend completely, then makes it be difficult for producing distortion fatigue, has longer application life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the sectional view of the section of embodiments of the invention.
In figure: 10, bottom, 11, draw-in groove; 20, sealing; 30, raised line, 31, hollow cavity, 32, air-vent.
The specific embodiment
Embodiment, as shown in Figure 1: door and window sealing strip, comprise smooth bottom 10, the left end top of this bottom 10 is provided with the arc sealing 20 of the hanging shape extending to upper right side.That is between, the left end of the left end of this bottom 10 and sealing portion 20 connection, the right-hand member of this bottom 10 and the right-hand member of sealing portion 20, there is gap.Meanwhile, the upper surface of this bottom 10 is provided with the raised line 30 of at least 1 section semicircular in shape.Obviously, the trend of this raised line 30 is same as the integral body trend of sealing bar.This raised line 30 has hollow cavity 31, and has air-vent 32 on this raised line 30.And this doors and windows sealing strip adoption rubber-plastics material is one-body molded.Such as, a kind of preparation in this doors and windows sealing strip adoption EPDM, CR, EVA, SBR, NBR.Like this, the rigidity of unsettled sealing 20 at the beginning of extruding is minimum, and along with the carrying out of pushing, its rigidity has very big lifting, in conjunction with the support giving with this raised line 30, makes the sealing effectiveness of sealing bar fabulous.Meanwhile, under the support of this raised line 30, the root of sealing portion 20 is unlikely to overflexing, then makes it be difficult for producing distortion fatigue.
Further say, for the ease of assembling, the side of this bottom 10 is provided with draw-in groove 11.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
