Description
Technical field：
This utility model is related to a kind of two-stage buffer, belongs to buffer technology field.
Background technology：
All it is generally constant force buffer in the market, and buffers inefficient, dynamics is consistent, and service life is short.
Utility model content：
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of two-stage buffer.
A kind of two-stage buffer of the present utility model, it includes stretching tube, mechanical spring, fixed piston, sealing ring, activity
Piston, jump ring, piston rod, fairlead；Lower end inside stretching tube is provided with mechanical spring, is provided with Medium Oil in stretching tube,
Fixed piston is arranged on the inside of stretching tube, and the outer surface of fixed piston is provided with sealing ring, is provided with work on fixed piston
Consent, is provided with piston rod in the middle part of fixed piston, and the front end of piston rod is worn and is connected in fairlead, and fairlead is arranged on stretching
The front end of pipe, is socketed with movable piston on the downside of piston rod, the outer surface of movable piston is provided with sealing ring, arranges on piston rod
There is draw-in groove, jump ring is installed in draw-in groove.
The beneficial effects of the utility model are：Secondary buffer is facilitated implementation, and leading portion dynamics is little, the buffering of back segment great efforts
Device, and automatically reset, all accessories are effectively protected, easy to operate, high working efficiency is time-consuming.
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- mechanical springs；3- fixed pistons；4- sealing rings；5- movable pistons；6- jump rings；7- pistons
Bar；8- fairleads.
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, mechanical spring 2, fixes
Piston 3, sealing ring 4, movable piston 5, jump ring 6, piston rod 7, fairlead 8；Lower end inside stretching tube 1 is provided with mechanical spring
2, mechanical spring 2 causes antivibrator to automatically reset, and 1 load medium of stretching tube oil, fixed piston 3 are arranged on the inside of stretching tube 1,
And the outer surface of fixed piston 3 is provided with sealing ring 4, sealing ring 4 is realized piston seal during compression, is provided with fixed piston 3
Piston hole 31, when fixed piston compresses, allows oil by piston hole 31 so as to produce power, can be by the size in regulating piston hole 31
Control dynamics, the middle part of fixed piston 3 are provided with piston rod 7, and piston rod 7 plays a part of a positioning to all accessories, and
The front end of piston rod 7 is worn and is connected in fairlead 8, and fairlead 8 is arranged on the front end of stretching tube 1, and fairlead 8 is positioned to piston rod 7,
Seal whole antivibrator simultaneously, the downside of piston rod 7 is socketed with movable piston 5, and the outer surface of movable piston 5 is provided with sealing ring
4, draw-in groove is provided with piston rod 7, and jump ring 6 is installed in draw-in groove, when movable piston 5 compresses, activity does not produce dynamics, to Dacca
Resistance is produced during 6 position of spring.
Further, described Medium Oil is silicone oil.
The operation principle of this specific embodiment is：, by piston hole so as to produce dynamics, buffer is identical for hydraulic oil
In the case of the medium (silicone oil) of viscosity, realize that front end uses macropore piston by dual piston method, so as to cause dynamics little,
Rear end causes great efforts using aperture piston, and spring is placed in bottom makes buffer automatically reset；Using convenient.
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.
