Abstract
The utility model provides an equal-pressure sealing strip which comprises a mounting part and a sealing part, wherein the mounting part and the sealing part adopt an integrated structure; a cross section of the mounting part is an approximate pentagon; grooves are formed in the left side and the right side of the mounting part; the sealing part is 7-shaped and comprises a head part and a neck part; and the neck part is connected with the mounting part. The equal-pressure sealing strip has the benefits that the pressure of an outer equal-pressure cavity and the pressure outdoors are reduced, and the water tightness is enhanced.
Description
Technical field
The utility model belongs to the door-window sealing member field, especially relates to a kind of isobaric weather strip.
Background technology
The watertightness of casement window is to weigh the key factor of a casement window quality, its water resistance comprises the watertightness of glass and sash and the watertightness of sash and window frame, wherein, the watertightness of window frame and sash is except can also realizing by the design of equivalent pressure cavity realizing by being arranged at weather strip between sash and window frame, and the sealing of isobaric weather strip is determining the performance of equivalent pressure cavity.Between isobaric weather strip on market and window frame, coordinate tight ness rating not high, the bad phenomenon that easily causes roof leaking of window water proofing property.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of isobaric weather strip, especially is suitable for the sealing of lap gap between fan and window frame.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of isobaric weather strip, comprise installation portion and sealing, described installation portion and described sealing are the integral type structure, the cross section of described installation portion is the class pentagon, and the described installation portion left and right sides is provided with groove, and described sealing is " 7 " font, described sealing comprises head and neck, and described neck is connected with described installation portion.
Further, described installation portion is hollow-core construction.
Further, described hollow-core construction comprises two cavitys in left and right.
Further, two ends, described installation portion bottom surface are provided with chamfering.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, between isobaric weather strip and window frame, coordinate tight ness rating high, the sealing of window is better, plays the effect of waterproof.
The accompanying drawing explanation
Fig. 1 is cross sectional representation of the present utility model.
In figure:
1, installation portion 2, sealing 3, groove
4, hollow-core construction 5, chamfering 6, head
7, neck
The specific embodiment
As shown in Figure 1, the utility model comprises installation portion 1 and sealing 2, installation portion 1 is the integral type structure with sealing 2, the cross section of installation portion 1 is the class pentagon, installation portion 1 left and right sides is provided with groove 3, sealing 2 is " 7 " font, and sealing comprises head 6 and neck 7, and neck 7 is connected with installation portion 1; Installation portion 1 is hollow-core construction 4; Hollow-core construction 4 comprises two cavitys in left and right; Installation portion 1 two ends, bottom surface are provided with chamfering 5.
The course of work of this example: by installation portion 1, isobaric weather strip is arranged on to the surrounding of window frame, the design of installation portion 1 left and right groove 3 makes window frame can block isobaric weather strip, when the design of chamfering 5 is convenient to install, isobaric weather strip is embedded in the groove of window frame surrounding, the hollow-core construction 4 of installation portion 1 makes it be difficult for coming off with window frame, during Window closing, sash profile is withstood the head 6 of sealing 2, make head 6 produce the tight ness rating that certain deformation coordinates with window frame to increase isobaric weather strip, isobaric weather strip and external seal strip form outer equivalent pressure cavity, isobaric weather strip and interior weather strip form interior equivalent pressure cavity, when rainwater impacts, interior equivalent pressure cavity pressure is less than outer equivalent pressure cavity pressure, in connecting like this, the isobaric weather strip of outer equivalent pressure cavity will more be adjacent to sash profile under the effect of external pressure, make rainwater can't enter constant-pressure cavity, and under the effect of negative pressure rapidly from the equivalent pressure cavity drain hole drain.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
