Description
Technical field
The utility model is related to weather strip for automobile technical field, especially a kind of sealing strip for door frame of automobile.
Background technology
In high molecular material, rubber is since with good mechanical property and high resilience, elasticity modulus is very small, therefore
It is widely used in anti-vibration article.But on the whole, the mechanical strength of rubber material is relatively low, and wearability is poor, during movement
The frictional resistance of generation is big, also there is certain limitation in terms of media-resistant.
Solid straight strip knot is made by ethylene-propylene diene copolymer in traditional automobile door frame gasket structure complexity, sealing strip
Structure, the sealing strip compression deformation is small, and elasticity is poor, therefore sealing performance is relatively weak.
Utility model content
The technical problems to be solved in the utility model is：Overcome deficiency in the prior art, it is close to provide a kind of automobile door frame
Strip of paper used for sealing.
Technical solution is used by the utility model solves its technical problem：A kind of sealing strip for door frame of automobile, including under
Rubber skin is separately installed with the first seal assembly and the second seal assembly on lower rubber skin by two support portions, and described first
Seal assembly includes the first rubber skin, and the first rubber skin is triangular shape hollow pipe, and the first rubber skin inner cavity is provided with inner sponge cores,
First rubber skin inner wall is integrally formed with the stent of support inner sponge cores；Second seal assembly includes the second circular rubber
Rubber, the second rubber skin top are equipped with a plurality of bypass channel；It is connected between first rubber skin and the second rubber skin and divides up and down
The upper connecting portion of cloth and lower connecting portion are equipped with cavity between upper connecting portion and lower connecting portion.
Further, the inner sponge cores and the first rubber skin are concentric or eccentric structure.
Further, the first rubber skin top is equipped with water bar.
Further, the lower rubber skin bottom is integrally formed with sawtooth portion.
Further, the second rubber skin thickness is twice of the first rubber skin thickness.
The beneficial effects of the utility model are：The utility model is simple in structure, reasonable design, using polytetrafluoroethylene (PTFE) sponge
Core has extremely superior chemical stability and low-down friction coefficient, improves close as sealing material, polytetrafluoroethylene (PTFE)
The elasticity and intensity of strip of paper used for sealing extend the service life and sealing performance of sealing strip.
Description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
1. first rubber skin in figure, 2. inner sponge cores, 3. stents, 4. water bars, 5. times rubber skins, 6. second rubber skins,
7. bypass channel, connecting portion on 8., 9. times connecting portions, 10. support portions, 11. sawtooth portions.
Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows the composition related with the utility model.
Sealing strip for door frame of automobile as shown in Figure 1 including lower rubber skin 5, is divided on lower rubber skin 5 by two support portions 10
First seal assembly and the second seal assembly are not installed, first seal assembly includes the first rubber skin 1, the first rubber skin
1 is triangular shape hollow pipe, and 1 inner cavity of the first rubber skin is provided with inner sponge cores 2, and 1 inner wall of the first rubber skin is integrally formed with support
The stent 3 of inner sponge cores 2；Second seal assembly includes the second circular rubber skin 6, and 6 top of the second rubber skin is equipped with a plurality of
Bypass channel 7；The upper connecting portion 8 being distributed up and down and lower connecting portion 9, upper company are connected between first rubber skin 1 and the second rubber skin 6
Cavity is equipped between socket part 8 and lower connecting portion 9, upper connecting portion 8 is arc strip.
2 and first rubber skin 1 of inner sponge cores is concentric structure；First rubber skin, 1 top is equipped with water bar 4；Lower rubber
5 bottom of skin is integrally formed with sawtooth portion 11；Second rubber skin, 6 thickness is twice of 1 thickness of the first rubber skin.
This sealing strip for door frame of automobile is simple in structure, reasonable design, using polytetrafluoroethylene (PTFE) sponge core as sealing material,
Polytetrafluoroethylene (PTFE) has extremely superior chemical stability and low-down friction coefficient, improves the elastic and strong of sealing strip
Degree extends the service life and sealing performance of sealing strip.
The above embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, all equivalent change or modifications substantially made according to the spirit of the present invention should all cover the protection model in the utility model
In enclosing.
