Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
As depicted in figs. 1 and 2, the present invention provides a kind of noise insulation blocks, the sky being equipped with for filling automobile body side wall
Chamber, the noise insulation block include sound insulation block body, first be set on sound insulation block body buckle 2 and the second buckle 3, the first buckle 2
Different with the diameter of the second buckle 3, sound insulation block body has the drip fluid apertures 7 for allowing electrophoresis liquid to pass through.
Specifically, as depicted in figs. 1 and 2, the diameter of the first buckle 2 is greater than the diameter of the second buckle 3, the first buckle 2
It is set on the same side of sound insulation block body with the second buckle 3 and is stretched out towards the same side of sound insulation block body.First buckle 2
It is respectively set one with the second buckle 3, the first buckle 2 and the second buckle 3 are for being inserted into peace set on body side wall metal plate
It fills in hole, realizes that installation of the noise insulation block in body side wall cavity is fixed.
As shown in figure 3, two the first card-tight parts that the first buckle 2 inserting column 21 and be set on the first inserting column 21 including first
22, the V-shaped distribution of two the first card-tight parts 22 and be arranged symmetrically, one end of the first inserting column 21 and sound insulation block body fixation company
Connect, the one end of two the first card-tight parts 22 is fixedly connected with the other end of the first inserting column 21, two the first card-tight parts 22 it is another
The vertical range c that one end is located between the side of the first inserting column 21 and the end of two the first card-tight parts 22 is
The diameter of one buckle 2 is also the size maximum of the first buckle 2.Two the first card-tight parts 22 have elasticity, buckle 2 first
During being inserted into the mounting hole on body side wall metal plate, two the first card-tight parts 22 are shunk, so that the first buckle 2 can
Across mounting hole and clamping.
