Abstract

The invention provides an installation clip of an intumescent rubber product suitable for special-shaped installation holes, which relates to the field of automobiles and includes sheet metal and clips. In the present invention, convex special-shaped holes are used to eliminate the possibility of rotation from the structure, and the axis is symmetrically shaped along the dotted line. ZX plane symmetry) The expansion block can be universal (that is, the left and right sides are mutually installed), and the asymmetrical shape along the solid line can realize foolproofing. It can only be installed in a specific direction, not in the opposite direction; there is a possibility to cooperate along the installation direction. The design concept of clearance uses local elastic limit, combined with rigid limit to ensure tight installation and no shaking.

Description

A mounting clip for intumescent adhesive products suitable for special-shaped mounting holes

technical field

The invention relates to the field of automobiles, in particular to an installation clip of an intumescent rubber product suitable for special-shaped installation holes.

Background technique

The expansion glue is installed in the body-in-white bypass cavity in the welding workshop, and undergoes electrophoresis baking in the painting workshop, resulting in chemical changes: foaming, and sealing the cavity section and mounting holes after foaming, thereby blocking the sheet metal bypass cavity It can absorb vibration and air noise, and achieve the function of sound insulation and noise reduction.

However, because the existing single-buckle sound-insulating rubber block products use ordinary square holes, rectangular or circular holes, they will rotate under electrophoretic shock, and the positional deviation will lead to sealing failure. The existing buckles are installed on the sheet metal along the installation. There is a gap in the direction matching, which will cause shaking in this direction, which is unfavorable for the fixation of the product. The existing design cannot be foolproof when the sheet metal features are not obvious.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a mounting clip for intumescent rubber products suitable for special-shaped mounting holes, so as to solve the above-mentioned technical problems.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions to realize: an installation buckle for expansion rubber products suitable for special-shaped installation holes, including sheet metal and buckles,

The sheet metal is provided with a special-shaped hole, the special-shaped hole has a convex structure, and the buckle is clamped in the special-shaped hole;

The buckle includes an installation seat, a buckle spring, an upper limit and a lower limit, the buckle spring is installed on the side wall of the installation seat, and the upper limit and the lower limit are respectively installed on the installation seat side walls and bottom;

The snap elastic piece is combined with the local elastic limit of the left port of the special-shaped hole, and the upper limit and the lower limit are combined with the rigid limit of the right port of the special-shaped hole.

The convex special-shaped hole is used to eliminate the possibility of rotation from the structure, and the shape is symmetrical along the dotted line axis, and the left and right sides (the car has left bypass sheet metal and right bypass sheet metal, and the left and right sides are symmetrical along the ZX plane) The expansion rubber block can be universal (that is, the left and right sides are mutually installed), and the asymmetrical shape along the solid line can realize foolproofing. It can only be installed in a specific direction, and cannot be installed in the opposite direction;

Fitting along the installation direction is a design concept with gaps, using local elastic limit, combined with rigid limit, to ensure tight installation without shaking.

The beneficial effects of the present invention are:

In the present invention, convex special-shaped holes are used to eliminate the possibility of rotation from the structure, and the axis is symmetrically shaped along the dotted line. ZX plane symmetry) The expansion rubber block can be universal (that is, the left and right sides are mutually installed), and the asymmetrical shape along the solid line can realize foolproofing. It can only be installed in a specific direction, not in the opposite direction;

Fitting along the installation direction is a design concept with gaps, using local elastic limit, combined with rigid limit, to ensure tight installation without shaking.

Detailed ways

In order to make the technical means, creative features, goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific embodiments and accompanying drawings, but the following embodiments are only preferred embodiments of the present invention, not all of them. . Based on the examples in the implementation manner, other examples obtained by those skilled in the art without creative work, all belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in Figure 1-3, a mounting clip for intumescent adhesive products suitable for special-shaped installation holes, including sheet metal 1 and clip 2,

The sheet metal 1 is provided with a special-shaped hole 3, the special-shaped hole 3 has a convex structure, and the buckle 2 is clamped in the special-shaped hole 3;

The buckle includes an installation seat 201, a buckle spring 202, an upper limit 203 and a lower limit 204. The buckle spring 202 is installed on the side wall of the installation seat 201, and the upper limit 203 and the lower limit 204 are respectively installed on the installation seat. 201 side walls and bottom;

The snap elastic piece 202 is combined with the local elastic limit of the left port of the special-shaped hole 3 , and the upper limit 203 and the lower limit 204 are rigidly combined with the right port of the special-shaped hole 3 .

The convex special-shaped hole 3 is used to eliminate the possibility of rotation from the structure, and the axis is symmetrically shaped along the dotted line. Plane symmetry) The expansion block can be universal (that is, the left and right sides are mutually installed), and the asymmetrical shape along the solid line can be foolproof. It can only be installed in a specific direction, not in the opposite direction; there is a gap along the installation direction. The design concept of using the local elastic limit, combined with the rigid limit, ensures that the installation cooperates closely and does not shake.

In the present invention, unless otherwise expressly specified and limited, a first feature "on" or "under" a second feature may include direct contact between the first and second features, or may include the first and second features Not directly but through additional features between them. Also, the first feature being "above", "over" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is level higher than the second feature. The first feature is "below", "below" and "below" the second feature includes the first feature is directly below and diagonally below the second feature, or simply means that the first feature has a lower level than the second feature.

The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and descriptions are only preferred examples of the present invention, and are not intended to limit the present invention, without departing from the spirit and scope of the present invention.
