Limitation.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of frcition damper, including cylinder 1, cylinder 1
Upper end inner surface slidably connect compression bar 2, the internal end surface of compression bar 2 is fixedly connected with the first briquetting 3, the upper end of cylinder 1
Inner surface is fixedly connected with rubber tube 4, and the outer surface of the first briquetting 3 is fixedly connected with chamfer bevel rubber ring 5, inclination
The outer surface of chamfering rubber ring 5 is slidably connected at the inner surface of rubber tube 4 by chamfer bevel groove 6；
Inner surface is fixedly connected with support ring block 7 at the center of cylinder 1, and the lower end outside surface of compression bar 2 is slidably connected
Pressure spring 8 is slidably connected in the upper end outer surface of the inner surface of support ring block 7, compression bar 2.
The lower surface of compression bar 2 is fixedly connected with the second briquetting 9, when in use, when by pressure compression bar 2, drives the first pressure
Block 3 is depressed, and at this moment the chamfer bevel rubber ring 5 outside the first briquetting 3 rubs downwards in the chamfer bevel groove 6 in rubber tube 4
It slips dynamic, increases resistance, the first briquetting 3 depresses pressure spring 8 at this time, can carry out damping again by pressure spring 8.
The lower end inside surface of cylinder 1 is fixedly connected with corrugated rubber cylinder 10, and the second briquetting 9 is in pressure corrugated rubber cylinder 10
When, corrugated rubber cylinder 10 itself just has buffering and damping effect.
The inner surface of corrugated rubber cylinder 10 is fixedly connected with the first rubber ring 11, and the inner surface of the first rubber ring 11 is set
There is the first annular groove 12, the outer surface of corrugated rubber cylinder 10 is fixedly connected with the second rubber ring 13, the inside of the second rubber ring 13
Surface is equipped with the second annular groove 14, after depressing corrugated rubber cylinder 10, can make 10 compressive deformation of corrugated rubber cylinder, drive the first rubber ring
11 and 13 deformation of the second rubber ring, it can be improved cushion effect, when rebound, pass through corrugated rubber cylinder 10 and the first rubber ring 11 and second
The rebound of rubber ring 13 and the rebound of pressure spring 8, can jack up the second briquetting 9 and the first briquetting 3, and the rebound of compression bar 2 is driven to reset, this
When the upward sliding in chamfer bevel groove 6 of chamfer bevel rubber ring 5, since the upper end opening of chamfer bevel groove 6 is small, lower end
Opening is big, and in upward sliding, resistance is small, and structure is simple, and cost is relatively low.
