First connecting hole, the other end of the cushion dashpot are provided with sealing plate, the limit of one of invagination are provided on the buffering inside wall of cylinder
Position ring, in the cushion dashpot with stop collar cooperation it is fixed pressure relief plate is installed, the pressure relief plate center offers pressure release
Cushion dashpot is divided into two sections by hole, the stop collar, mobilizable in one section of cylinder body of the first connector to be provided with adjustable plate,
It is mobilizable in other end cylinder body to be provided with piston rod, pass through bolt on the piston rod and is removably connected with piston, it is described
Piston is slidably matched with the buffering inside wall of cylinder, and the piston rod stretches out the sealing plate, and is fixedly connected in piston-rod end
There is the second connector, it is perforative on second connector to offer the second connecting hole.
Compared with the prior art, the utility model has the following beneficial effects:
A kind of buffer provided by the utility model is provided with three layers of buffer in the utility model in a cushion dashpot
System, one of which are to utilize piston rod buffer function caused by the intracorporal compression of the other end cylinder or elongation；Another layer
Buffering is when another intracorporal pressure of cylinder is sufficiently large, and high-pressure fluid passes through pressure relief plate out of described other end cylinder body
On relief hole pressure release in one end cylinder body, and then so that cylinder body between pressure relief plate and piston, and let out
Cylinder body between pressing plate and adjustable plate realizes pressure intercommunication, thus by cylinder body damper piston between pressure relief plate and adjustable plate with
The pressure of cylinder body between pressure relief plate plays further buffer function；The last layer buffering is that adjustable plate is in described one end
It can be slided in cylinder body, when the pressure between pressure relief plate and adjustable plate is much larger than the pressure between adjustable plate and the first connector
When, adjustable plate is mobile to the first connector under pressure, the pressure of further damper piston, to realize three layers of buffer
System, the component that can be connected to effective protection on the second connector of piston-rod end, the utility model structure is simple, manufacturing cost
It is low, good buffer effect.
Detailed description of the invention
Fig. 1 is the external structure schematic diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model；
Fig. 3 is the main view in the utility model.
Specific embodiment
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
As shown in Figure 1-Figure 3, as a kind of preferred embodiment of the utility model, the utility model proposes a kind of bufferings
Device, including cushion dashpot 10, described 10 one end of cushion dashpot are fixedly connected with the first connector 11,11 end of the first connector at
Spherical, the spherical two sides offer connecting end surface, perforative between two connecting end surfaces to offer the first connection
Hole 12, the other end of the cushion dashpot 10 are provided with sealing plate 13, the limit of one of invagination are provided on 10 inner wall of cushion dashpot
Position ring 14 cooperates with the stop collar 14 in the cushion dashpot 10 and fixed is equipped with pressure relief plate 15,15 center of pressure relief plate
Relief hole is offered, the diameter of the relief hole is 1-4mm, and cushion dashpot is divided into two sections by the stop collar 14, is connected close to first
It is mobilizable in one section of cylinder body of connector 11 to be provided with adjustable plate 16, it is mobilizable in other end cylinder body to be provided with piston rod 17,
Piston 19 is removably connected with by bolt 18 on the piston rod 17, the piston 19 is slided with 10 inner wall of cushion dashpot
Cooperation, the piston rod 17 stretches out the sealing plate 13, and is fixedly connected with the second connector 20 in 17 end of piston rod, described
It is perforative on second connector 20 to offer the second connecting hole 21；By being set in periphery on the piston 19 and adjustable plate 16
Rubber seal and cushion dashpot 10 on face is in sealing contact.
Three layers of buffering are provided in above scheme in a cushion dashpot 10, one of buffer function is to utilize work
The buffer function caused by the intracorporal compression of the other end cylinder or elongation of stopper rod 17；Another layer of buffering is when described another
When the intracorporal pressure of one cylinder is sufficiently large, high-pressure fluid is out of described other end cylinder body through the relief hole on pressure relief plate 15 described in
Pressure release in the cylinder body of one end, and then so that cylinder body and pressure relief plate 15 between pressure relief plate 15 and piston 19 and adjust
Cylinder body between plate 16 realizes pressure intercommunication, thus by cylinder body damper piston 19 between pressure relief plate 15 and adjustable plate 16 with let out
The pressure of cylinder body between pressing plate 15 plays further buffer function；The last layer buffering is that adjustable plate 16 is described one
Can be slided in the cylinder body of end, when the pressure between pressure relief plate 15 and adjustable plate 16 much larger than adjustable plate 16 and the first connector 11 it
Between pressure when, adjustable plate 16 is mobile to the first connector 11 under pressure, the pressure of further damper piston 19, thus
Realize three layers of buffering, the component that can be connected to effective protection on the second connector of piston-rod end 20, the utility model
Structure is simple, and manufacturing cost is low, good buffer effect.
Preferably, the pressure relief plate 15 is also fixedly connected with buffering elastic on one end end face of the adjustable plate 16
Spring 22.In action process, especially when piston rod 17 stretches out cushion dashpot 10, the pressure in cushion dashpot is gradually reduced, at this time
Adjustable plate 16 can be mobile towards pressure relief plate 15, when 16 movement speed of adjustable plate is very fast, is easy to hit with pressure relief plate 15, because
Buffer spring 22 is arranged on the end face of pressure relief plate 15 for this it is possible to prevente effectively from the generation hit, protects buffer internal structure.
Preferably, the axis co-planar of first connecting hole 11 and the second connecting hole 20.The axis of two connecting holes
It is more convenient to be connect with shielded component when coplanar, especially in stress, when the axis co-planar of two connecting holes, it will not go out
Existing torsion force helps to protect buffer.
Above-mentioned buffer realizes internal, external protective effect by three layers of buffering inside cushion dashpot 10, slow
During punching, do not need to entering and leaving buffer medium in buffer again, it is only necessary to during installation, it is disposable inject buffer pressure oil or
Person's protective gas, use are very convenient.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
