Disclosure of Invention
The utility model aims to provide a fixing connector for an automobile.
To achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a fixed connection spare for car, including inserting the plastics buckle of car body panel beating in and fixed connection decorative board, be provided with the elastic sealing disk on the plastics buckle, the elastic sealing disk is located one side that car body panel beating is close to the connection decorative board, is provided with the sealing member of laminating with car body panel beating extrusion on the elastic sealing disk, the sealing member adopts foaming agent PU foaming form to make.
Further, the cross-sectional shape of the sealing element adopts a 'water drop' structure, and the sealing element is positioned at the inner end part of the elastic sealing disc.
Further, the bottom of the plastic buckle is provided with a clamping part fixedly connected with the decorative plate.
Further, the plastic buckle comprises a buckle body, a plurality of spring plates and a back-off, the spring plates can be extruded to shrink inwards to deform, the elastic sealing disc is arranged on the outer edge of the buckle body, the sealing piece is adhered to the end edge of the elastic sealing disc, and when the plastic buckle is clamped with the metal plate of the automobile body, the spring plates are abutted against the hole wall of the metal plate of the automobile body.
Further, the afterbody of every spring plate all is provided with the back-off of inwards warping, and the outer fringe of a plurality of back-offs all contradicts with the pore wall of car body panel beating.
Further, an extension part is arranged between the elastic sealing disc and the clamping part.
The utility model has the beneficial effects that: the sealing element of the fixing connecting piece for the automobile adopts the foaming agent PU, and the required sealing element can be obtained only by coating and standing foaming on the elastic sealing disc according to the known shape, and the sealing element does not need a die, has a short development period, can be produced at any time according to drawings, and has high production speed and low cost by adopting pipelining operation. Because the foaming material has softer texture, the fault tolerance range is larger when the scene compression sealing is used, the sealing effect is better, and the aging resistance can be realized for a longer time.
Drawings
In order to more clearly illustrate the technical solution of the embodiments of the present utility model, the drawings that are required to be used in the embodiments of the present utility model will be briefly described below.
FIG. 1 is a cross-sectional view of a stationary connector;
FIG. 2 is a cross-sectional view of the mounting state of the stationary connector;
FIG. 3 is a schematic perspective view of the installation state of the present utility model;
in the figure: 1-a plastic buckle; 1 a-a clamping part; 1 b-buckling body; 1 c-spring plate; 1 d-extension; 1 e-an elastic sealing disc; 1 f-back-off; 2-a seal; 3-sheet metal of the automobile body; 4-decorative board.
Detailed Description
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to be limiting of the present patent; for the purpose of better illustrating embodiments of the utility model, certain elements of the drawings may be omitted, enlarged or reduced in size and do not represent the actual product dimensions.
Referring to the fixed connection spare for car that fig. 1 through 3 show, including inserting the plastics buckle 1 and the sealing member 2 of pasting on plastics buckle 1 elastic sealing disk 1e of car body panel beating 3 and fixed connection decorative board 4, sealing member 2 adopts foaming agent PU foaming form to make, only need according to known shape coating and standing foaming on plastics buckle 1 elastic sealing disk 1e, can obtain the fixed connection spare for car that needs, and this application does not need the mould, and the development cycle is short can be produced at any time according to the drawing, adopts pipelining production fast, with low costs. Because the foaming material has softer texture, the fault tolerance range is larger when the scene compression sealing is used, the sealing effect is better, and the aging resistance can be realized for a longer time.
One side that plastics buckle 1 elastic sealing disk 1e and car body panel beating 3 laminate is provided with sealing member 2, and sealing member 2 cross sectional shape adopts similar "water droplet" structure, and foaming round along elastic sealing disk 1e edge for sealing member 2 can take place extrusion deformation, and the face that extrusion deformation produced is sealed with car body panel beating 3 surface laminating, increases sealing area through this kind of mode, improves the sealing grade.
