[0002] Shock-absorbing rubber is commonly used in structural parts to prevent vibration and impact transmission because of its excellent ability to buffer vibration and impact strength. It is widely used in various motor vehicles, equipment and instruments, industrial equipment, automated office facilities and household appliances. The current shock-absorbing rubber simply uses its own resilience to achieve elastic shock absorption and reset. However, due to its limited extrusion and rebound performance, its shock absorption is also relatively limited, the shock absorption performance cannot be adjusted, and the applicable scenarios are not wide enough. Utility Model Content

[0005] The internal support blind holes are composed of three first support blind holes arranged in a circular array and three second support blind holes arranged in a circular array.

[0006] A hollow shock-absorbing chamber is provided at the bottom inside the support column, and an arc-shaped limiting groove is provided at the lower end of the inner side surface of the second support blind hole.

[0007] The inner hole depth of the first supporting blind hole is the same as the height of the supporting column, and the inner hole depth of the second supporting blind hole is less than the height of the supporting column.

[0008] The first supporting blind hole and the second supporting blind hole are arranged inside the annular receiving groove at intervals.

[0009] The annular receiving groove and the inner assembly surface of the auxiliary support ring are provided with arc-shaped control grooves for easy separation.

[0010] The beneficial effects of the utility model are:

[0011] (1) The combined shock-absorbing rubber of the utility model can change the shock-absorbing reset stroke as needed by adopting a combined structural design, thereby greatly improving the shock-absorbing effect;

[0012] (2) By adopting a detachable design, it is convenient to use the shock-absorbing components according to needs, thereby improving the scope of application;

[0013] (3) By adopting a deep and shallow design, it is convenient to store or unfold as needed, which is convenient for storage;

[0014] (4) By providing a hollow shock-absorbing chamber at the bottom of the support column, the shock absorption performance can be improved while ensuring the anti-loosening performance, and the safety is also better. BRIEF DESCRIPTION OF THE DRAWINGS
