Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model discloses a car back of body door buffer, as shown in fig. 1-3, this car back of body door buffer includes: a buffer device body 6; the damper body 6 includes:
a first fixed part 1; a second fixing portion 2 integrally formed with the first fixing portion 1; the first fixed connecting part 3 is correspondingly connected with the vehicle body mounting hole; and a second fixed connecting part 4 connecting the first fixed connecting part 3 and the first fixed part 1 and integrally formed with the first fixed connecting part 3 and the first fixed part 1;
wherein, the first fixed part 1 is provided with a cylindrical groove 5, and at least part of the second fixed part 2 is fixed in the cylindrical groove 5;
the first fixing portion 1, the second fixing portion 2, the first fixing connection portion 3, and the second fixing connection portion 4 are axisymmetric.
The first fixing portion 1 is a cylindrical structure, and the diameter of the first circular end surface 11 of the cylindrical structure is smaller than the diameter of the second circular end surface 12.
The second fixing portion 2 is a cylindrical structure, wherein the diameter of the cylindrical structure is smaller than that of the cylindrical groove 5.
The first fixed connecting part 3 is a cylindrical structure, and the diameter of the third round end surface 31 of the cylindrical structure is smaller than that of the fourth round end surface 32; the diameter of the fourth round end surface 32 is smaller than that of the second round end surface 12; and the fourth rounded end surface 32 is opposite the second rounded end surface 12.
The second fixed connection portion 4 is a cylindrical structure, and the cylindrical structure is disposed between the second circular end surface 12 and the fourth circular end surface 32, and the diameter of the end surface of the cylindrical structure is smaller than the diameter of the fourth circular end surface 32.
The damping device body 6 is made of rubber material.
When the automobile body fixing device is installed, the fixing connecting part 3 is directly screwed into an automobile body mounting hole to be tightly matched with the automobile body mounting hole, and the second round end face 12 of the first fixing part 1 can completely block the periphery of the automobile body mounting hole to play the roles of water prevention and sealing.
