Specific embodiment
In order to be more clearly understood to technical characteristic of the invention, purpose and effect, now compare accompanying drawing and describe in detail
Specific embodiment of the invention.
As Figure 1-Figure 11, the present invention includes support arm 1, stretcher 3 and column for the vibration damping stretcher device of vehicle equipment
2.Column 2 is provided with multiple lock holes 4, and different height is designed with lock hole 4, and sustained height also is provided with multiple lock holes
4.Support arm 1 is sleeved on the outside of column 2, and support arm 1 is fixed in lock hole 4 by stop pin 6.Stretcher 3 is placed on support arm 1, is stood
The upper and lower ends of post 2 are all fixed on vehicle equipment.The upper end of column 2 is connected by Quick-release pin 23 with upper connector 24.Column 2
Lower end be connected with lower connector 26 by Quick-release pin 25.The bottom of stretcher 3 is provided with leg 27, and support arm 1 is provided with mounting groove 28,
Connected in the insertion mounting groove 28 of leg 27 and by Quick-release pin 29.Upper connector 24 is connected and lower connector 26 is fixed on delivery and sets
It is standby upper.
The inside of column 2 sets damper mechanism, and it includes guide cylinder 30, middle stator 17 and sets up separately in middle stator 17
The upper fixed cover 18 and lower fixed cover 19 of upper and lower both sides.Upper spring 21 is set between middle stator 17 and upper fixed cover 18, in
Between lower spring 20 is set between stator 17 and lower fixed cover 19, upper spring 21 and lower spring 20 are sleeved on the outside of guide cylinder 30.
Middle stator 17, upper fixed cover 18, lower fixed cover 19 are fixedly connected by screw 22 with column 2 respectively.
When vehicle equipment causes column 2 to move upwards due to vibration, column 2 can drive lower spring 20 to move upwards, under
Spring 20 compresses, so as to reach the effect of vibration damping.Similarly, when vehicle equipment causes column 2 to move downward due to vibration, column
2 can drive spring 21 to move downward, and upper spring 21 compresses, so as to reach the effect of vibration damping.
