Preferably, being provided with fixing hole on described rear stifled shell.
The beneficial effects of the utility model are：Using front fast rear slow formula buffering, buffer time can be both met, can reach again
It is to complete muting function, easy to use, it is easy to operate.
Description of the drawings：
For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is structural representation of the present utility model.
In figure：1- stretching tubes；2- movable pistons；Block up after 3-；4- mechanical springs；5- sealing rings；6- fixed pistons；7- pistons
Bar；8- fairleads；9- union joints.
Specific embodiment：
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below by what is illustrated in accompanying drawing
Specific embodiment is describing this utility model.However, it should be understood that these descriptions are simply exemplary, and it is not intended to limit this reality
With new scope.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in figure 1, this specific embodiment is employed the following technical solutions：It includes stretching tube 1, movable piston 2, blocks up afterwards
3rd, mechanical spring 4, sealing ring 5, fixed piston 6, piston rod 7, fairlead 8, union joint 9；The inside of stretching tube 1 is marked with silicone oil,
The rear end of stretching tube 1 blocks up 3 after being provided with, and blocks up after blocking up the plastics with sealing member afterwards, forbids silicone oil to lead to bottom, and bottom brill is logical
Hole, facilitates the fixation and installation of product, blocks up afterwards and is provided with sealing member on 3, and mechanical spring 4 is arranged on the lower end inside stretching tube 1,
The front end of mechanical spring 4 is provided with movable piston 2, and mechanical spring 4 allows movable piston 2 to realize automatically reseting, pacifies on movable piston 2
Equipped with piston hole 21 is provided with sealing ring 5, and movable piston 2, sealing member sealing piston periphery when movable piston 2 compresses allows
Oil can not only produce resistance by piston hole so as to produce power during stretching, the front end of stretching tube 1 is provided with fairlead 8, fairlead
Position piston rod, and seal whole antivibrator, the inside of fairlead 8 is worn and is connected to piston rod 7, the rear end of piston rod 7 is installed
There is fixed piston 6, be provided with fixed piston 6 on sealing ring 5, and fixed piston 6 and be provided with piston hole 21, fixed piston is fixed
On piston rod, with piston rod activity, sealing member sealing piston periphery during compression, allow oil pass through piston hole so as to produce
Power, does not produce resistance during stretching, the front end of piston rod 7 is provided with union joint 9, and union joint is fixed on piston rod, and top is with circle
Hole, convenient fixed product..
Further, connecting hole is provided with described union joint 9.
Further, fixing hole is provided with described rear stifled 3 shell.
The operation principle of this specific embodiment is：Sealing buffer tubes bottom, bottom holes drilled through and top is blocked up after buffer
The union joint of the piston rod fixed belt hole in portion, it is convenient to fixedly mount.Compression buffer during use, the piston of piston rod are lived downwards
Dynamic, the periphery of sealing member sealing piston makes oil pass through by the hole on piston, so as to produce power.In the silicone oil of same media
Space under, the piston of fixed piston rod adopts macropore, and dynamics is less than normal, and movable piston adopts piston hole less than normal, and dynamics is bigger than normal,
When compression distance reaches movable piston, dual piston produces power, so as to accomplish level 2 buffering, it is fast before secondary buffer after
Slowly, buffer time can have both been met, complete muting function can have been reached again.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model.This utility model
Claimed scope is by appending claims and its equivalent thereof.
