Abstract
The utility model discloses a sealing strip for a coach pneumatic door. The sealing strip comprises a clamping part connected under a sealing lip; the clamping part comprises two blocking grooves fixed with a door side in a matching way; the outer groove wall of each blocking groove is longer than the inner groove wall of the blocking groove; the outer groove walls of the two blocking grooves are respectively inclined inwards, so that a reversed V shape can be formed. According to the sealing strip for the coach pneumatic door, the two outer groove walls of the blocking grooves of the clamping part form a reversed V-shaped opening, so that the contact area between the clamping part and an assembled part can be enlarged, and the static friction force of the assembled part is further increased; sealing strip is easy to assemble while guaranteeing fixation to be reliable, and is attractive in appearance; after the sealing strip is adopted, the phenomena of being loosened and falling off can be guaranteed to be avoided in the using process; a weight reduction through hole is arranged, so that a great deal of raw material is saved, and the whole sound insulation of the sealing strip is improved.
Description
Technical field
The utility model relates to automotive sealant production field, is specifically related to a kind of passenger vehicle pneumatic door sealing band.
Background technology
the sealing band of installing on the pneumatic door of passenger vehicle left and right can play the effect of dustproof sound insulation; existing sealing band only relies on the Clamping force between draw-in groove and fabricated section to fix; outer side edges and the inner side edge of holding part are isometric, little with the contact surface of fabricated section, therefore often there will be the phenomenon coming off.And existing gasket structure raw materials requirement when moulding is larger, productive costs is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of passenger vehicle pneumatic door sealing band, increases the Clamping force between sealing band and fabricated section, the good and conservation of soundproof effect.
The utility model is achieved through the following technical solutions:
A kind of passenger vehicle pneumatic door sealing band, comprise the holding part being connected under sealing lip limit, holding part consists of two draw-in grooves that are fixed with door limit, and the external groove sidevall length of described each draw-in groove is longer than internal groove side wall, and the external groove sidevall of described two draw-in grooves slopes inwardly respectively and is herringbone.
The further improvement project of the utility model is that the inclination angle of described external groove sidevall is 10-30 °.
The utility model further improvement project is along sealing band length direction, to be provided with some loss of weight cavitys on the entity between described lip limit and holding part.
Compared to the prior art the utility model has the following advantages:
Two external groove sidevalls of holding part draw-in groove of the present utility model are the opening of herringbone, thereby the contact surface that can increase holding part and assembly parts increases the static friction force with assembly parts, guarantee that fixedly failure-free is easy to assembling simultaneously, image is attractive in appearance, guarantee in use not occur the phenomenon of loose or dislocation, a large amount of raw-material sound-proofings that simultaneously improve sealing band integral body are saved in offering of loss of weight through hole.
Accompanying drawing explanation
Fig. 1 is the utility model end view.
The specific embodiment
A kind of passenger vehicle pneumatic door sealing band as shown in Figure 1, comprise the holding part 2 being connected under sealing lip limit 1, holding part 2 consists of two draw-in grooves 3 that are fixed with assembly parts, external groove sidevall 31 length of each draw-in groove 3 are longer than internal groove side wall 32, the external groove sidevall 31 of two draw-in grooves 3 slopes inwardly respectively 10 ° and forms a herringbone, thereby this structure can increase the contact surface increase of holding part 2 and assembly parts and the static friction force of assembly parts, guarantees that fixedly failure-free is easy to assemble vivid attractive in appearance simultaneously.
On entity in the present embodiment between lip limit 1 and holding part 2, along sealing band length direction, be provided with some loss of weight cavitys 4, loss of weight cavity 4, all about the end surface symmetric rotational symmetry of sealing band, has improved the sound-proofing of sealing band integral body in the time of conservation.
Claims (3)
