Examples

Referring to fig. 1 to 4, an embodiment of the present invention includes: the utility model provides a seat back shim for car, includes first gasket 5 and second gasket 6, and connecting pipe 4 is installed in the embedding of 5 lower surfaces of first gasket, and 5 upper surfaces of first gasket are equipped with second skid

resistant course

3, and 3 upper surfaces of second skid resistant course and the 4 tops of connecting pipe are in the coplanar. Through setting up second skid resistant course 3 thereby make first gasket 5 and connection structure when being connected stability promote. An external thread 8 is arranged on the outer wall of the connecting pipe 4 below the first gasket 5, a nut sleeve 7 is arranged at the bottom of the connecting pipe 4 in a threaded mode, and the top end of the nut sleeve 7 and the upper surface of the second gasket 6 are located on the same plane. The nut sleeve 7 is arranged so that the connecting pipe 4 can be rotationally displaced up and down in the second gasket 6.

The nut sleeve 7 is embedded and installed on the inner side of the second gasket 6. The lower surface of the second gasket 6 is provided with a first anti-slip layer 1, the lower surface of the first anti-slip layer 1 and the bottom end of the nut sleeve 7 are positioned on the same plane, and the lower surface of the first anti-slip layer 1 and the bottom end of the connecting pipe 4 are positioned on the same plane. Through setting up first skid resistant course 1 to stability when making second gasket 6 be connected with connection structure promotes. The rubber gasket 2 is sleeved on the connecting pipe 4 on one side, opposite to the first gasket 5 and the second gasket 6, of the connecting pipe, and the inner wall of the rubber gasket 2 is not in contact with the external thread 8 on the outer wall of the connecting pipe 4. By sleeving the rubber gasket 2 on the connecting pipe 4, a buffer exists between the first gasket 5 and the second gasket 6, and the rubber gasket 2 provides a better buffer when the first gasket and the second gasket are close to each other to the maximum extent. The rubber gasket 2 is sleeved on the connecting pipe 4 on one side, opposite to the first gasket 5 and the second gasket 6, of the connecting pipe, and the inner wall of the rubber gasket 2 is not in contact with the external thread 8 on the outer wall of the connecting pipe 4. By sleeving the rubber gasket 2 on the connecting pipe 4, a buffer exists between the first gasket 5 and the second gasket 6, and the rubber gasket 2 provides a better buffer when the first gasket and the second gasket are close to each other to the maximum extent. Through setting up first gasket 5 and second gasket 6, and set up connecting pipe 4 in first gasket 5 and the relative one side of second gasket 6, through with connecting

pipe

4 and 5 fixed connection of first gasket, and make connecting

pipe

4 and 6 threaded connection of second gasket through nut cover 7, thereby when first gasket 5 atress is rotatory, connecting pipe 4 accessible nut cover 7 moves to 6 below of second gasket, and after moving one end distance, 2 chucking of rubber packing ring are in first gasket 5 and the relative one side of second gasket, thereby produce the buffering to the vibration, and then improve the locking power of gasket, the effect that has improved structural stability has been reached.

The working principle is as follows: when the rubber gasket is installed, the rubber gasket 2 is sleeved on the connecting pipe 4, the connecting pipe 4 is screwed into the second gasket 6 provided with the nut sleeve 7 through the external thread 8, when the rubber gasket is used, the bolt penetrates through the connecting pipe 4 and is screwed so as to be fixedly installed on an installation part through the nut, at the moment, the bolt is continuously screwed so as to drive the first gasket 5 and the connecting pipe 4 to rotate, so that the connecting pipe 4 penetrates through the opening of the installation part and is contacted with the nut, under the condition of continuous screwing, the connecting pipe 4 is deformed so as to shorten the length, at the moment, the first gasket 5 is close to the second gasket 6 and applies force to the rubber gasket 2, so that the rubber gasket 2 is tightly clamped on one side, opposite to the first gasket 5 and the second gasket 6, and the effect of buffering vibration is achieved.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
