Space further includes a pair of of bayonet.The program, which uses, respectively symmetrically sets a pair mutually to block with retaining rail on bumper support both sides
Tight bayonet arrangement.The program supporting without alluvium and guide frame in itself, it is necessary to additionally add guide rail for alluvium
With stent, program guide rail is still independently separated with buffer, and positioning is more difficult during assembling.
The content of the invention
It is an object of the invention to provide a kind of twin ring spring buffer units, are meeting buffer pooling feature
It has supporting and the effect being oriented to concurrently simultaneously, overcomes conventional motion body buffer unit and multigroup guide rail and assembling caused by stent are set
The problems such as location difficulty, mass of system are excessive, reliability is low.
Realize the object of the invention solution be:A kind of twin ring spring buffer unit, including first annular outer
Circle, the second annular outer ring, the first connecting plate, the second connecting plate, shell and two groups of buffer cells, first annular outer ring and the second ring
Shape outer ring parallel interval is set inside the shell, and first annular outer ring inner wall is arranged with a pair of of mounting hole, in the second annular outer ring
Wall is arranged with a pair of of mounting hole, and one group of buffer cell is also cross a mounting hole on first annular outer ring and the second annular
A mounting hole on outer ring, movable body are set inside the shell, and pass through first annular outer ring and the second annular outer ring, movable body
One end is connected with the first connecting plate center, and the other end is connected with the second connecting plate center, and the first connecting plate both ends are respectively fitted over slow
It rushes on unit, the second connecting plate both ends are respectively fitted on buffer cell.
Compared with prior art, the present invention its remarkable advantage is to have:(1)Buffer cell has supporting and the effect being oriented to concurrently,
Instead of the multigroup stent and guide rail set in conventional buffer, facilitate assembling and position, alleviate mass of system, improve
The reliability of system;(2)When buffer works, each group thread connector is not born directly by axial impact loading, is coupled tight
Close, reliability is high;(3)Buffer unit compact overall structure, simple structure, manufacture easy to process;(4)Cushion performance is by temperature shadow
