Description

A kind of position, hole seals structure

Technical field

This utility model relates to vehicle component, is specifically related to a kind of position, hole and seals structure.

Background technology

In recent years, along with consumer is more and more higher to automotive quality and self organoleptic requirements, the sealing requirements of car load was also More and more higher, in vehicle manufacturing process, in order to weld, leakage and assembly technology requirement, manufacturer can be at body in white metal plate Offer corresponding position, hole on gold, but before car load rolls off the production line, this some holes must block with blanking cover, otherwise will produce and leak, Noise, the problem such as vibrations, affect car load sealing.In existing automobile sealed design structure, usually sheet metal adds gluing Technique seals, metal stopple as shown in Figures 1 and 2, and metal stopple 2 is filled in stamping holes position 1, and metal stopple 2 is outside Sealed by application fluid sealant 3, i.e. in prior art, ensured the sealing of position, hole by application gluing technique.

Sealing frame mode shown in Fig. 1 with Fig. 2 has the disadvantage that: 1. owing to stopple is metal, add car load weight Amount；2. gluing process influence productive temp, waste man-hour and repetitive operation are sealed；3. metal resistant is not strong, has corrosion Hidden danger.Accordingly, it would be desirable to design a kind of position, hole to seal structure to solve problem above.

Utility model content

This utility model provides a kind of position, hole and seals structure, and its sealing is strong, assembling is simple and operation saves time.

For achieving the above object, this utility model provides following technical scheme:

A kind of position, hole seals structure, including seal body, described seal body include for panel beating upper surface pressing Expose block, described in expose the inner side of block and be fixed with built-in pipe, the outer wall of described built-in pipe is provided with for the peace with described panel beating The resilient barb clamp that matches of dress hole, the material of described seal body is plastics, described in expose and be equipped with at block inside edge PUR.

Preferably, expose, described in, the edge fitted with described panel beating inside block and be provided with profile of tooth cell body, described PUR It is contained in described serrate slot body.

Preferably, described profile of tooth cell body is the most stepped.

Preferably, described seal body material is polyamide 6 or nylon 6 or thermoplastic elastomer (TPE).

Preferably, expose block, built-in pipe and resilient barb clamp described in and be integrated injection mo(u)lding.

Preferably, described hot melt adhesive material is ethylene-vinyl acetate copolymer.

The beneficial effects of the utility model are:

The position, hole that this utility model provides seals structure, has resistant to elevated temperatures seal body, exposes in block in seal body It is equipped with PUR at lateral edges, in use, seal body is pressed in the stamping holes position of respective aperture, makes resilient barb card Subcard, at the inwall of stamping holes position, can pass through Painting Shop high temperature station, make PUR by high temperature melt bonding with panel beating one Body, it is achieved thereby that fully seal stamping holes position, has cut off the infiltration of water and gas effectively.

Detailed description of the invention

In order to make those skilled in the art can be further understood that feature of the present utility model and technology contents, below in conjunction with This utility model embodiment is elaborated by drawings and embodiments.

It is the schematic diagram of position, this utility model embodiment hole sealing structure as shown in Figures 3 to 5, including: seal body 5, Described seal body 5 includes exposing block 7 for panel beating upper surface pressing, is fixed with built-in pipe 8 in the inner side exposing block, built-in The outer wall of pipe is provided with the resilient barb clamp 9 for matching, wherein, described seal body 5 with the installing hole of described panel beating Material be plastics, described in expose and be equipped with PUR 6 at block 7 inside edge.

It should be noted that PUR is a kind of plastic binding agent, room temperature is solid state, can be fast after heating and melting Speed is bonding, and PUR cements from gluing to cooling, it is only necessary to Ji Shimiao, the time of the most several seconds.

Specifically, described in expose and at block 7 inside edge, be provided with profile of tooth cell body, described profile of tooth cell body is used for housing described heat Melten gel 6.As shown in Figure 6, in order to corresponding with described profile of tooth cell body, in this utility model embodiment, PUR 6 ladder ringwise Shape.Certainly, described profile of tooth cell body is the most stepped.

Specifically, expose block 7, built-in pipe 8 and resilient barb clamp 9 described in and be integrated injection mo(u)lding.

Specifically, described seal body material is polyamide 6 or nylon 6 (PA6) or thermoplastic elastomer (TPE) (TPE).

Specifically, described hot melt adhesive material is ethylene-vinyl acetate copolymer (EVA).

It should be noted that in this utility model embodiment, be greater than coating process owing to seal body self is high temperature resistant High-temperature temperature, within the most high temperature resistant 220 DEG C, therefore, during use by vertically-mounted for seal body behind corresponding panel beating aperture, By Painting Shop high temperature station, the PUR of himself band is met high temperature melt and is quickly bonded together with panel beating.

The sealing structure that this utility model embodiment provides, has resistant to elevated temperatures seal body, exposes block in seal body It is equipped with PUR at inside edge, in use, seal body is pressed in the stamping holes position of respective aperture, makes resilient barb Clamp is stuck in the inwall of stamping holes position, can pass through Painting Shop high temperature station, make PUR bonding with panel beating by high temperature melt Integrally, it is achieved thereby that stamping holes position is fully sealed, the infiltration of water and gas has effectively been cut off.This utility model is implemented The sealing mechanism of example offer is that a kind of sealing is strong, assembling is simple, operation saves time and has position, the hole sealing structure of weight advantage.

Being described in detail this utility model embodiment above, detailed description of the invention used herein is to this practicality Novel being set forth, the explanation of above example is only intended to help and understands this utility model；Simultaneously for this area one As technical staff, according to thought of the present utility model, the most all will change, to sum up Described, this utility model content should not be construed as restriction of the present utility model.
