【Specific embodiment】
Refer to shown in Fig. 3-5, bicycle saddle cushion elevating adjusting device 2 of the present utility model is arranged in one first pipe fitting
The two after 2A and one second pipe fitting 2B is combined is internal；The second pipe fitting 2B tops are affixed with seat cushion, the bottom of first pipe fitting 2A
End is affixed with bicycle frame.The bottom of second pipe fitting 2B is penetrated in first pipe fitting 2A by the top of first pipe fitting 2A
Portion.Wherein, the bicycle saddle cushion elevating adjusting device 2 is an oil hydraulic cylinder, is had：
One cylinder barrel 2C, as shown in Figure 5.Cylinder barrel 2C includes an outer tube 20 and an inner tube 21, and the length of inner tube 21 is outer compared with this
Pipe 20 is short, and the inner tube 21 is fixedly arranged on the inside of outer tube 20 and has a gap 22 therebetween.The two ends of the inner and outer pipe 21,20 point
Ju You not the mouth of pipe 211,201 of one first mouth of pipe 210,200 and 1 second, the difference of first, second mouth of pipe 200,201 of the outer tube 20
Sealed by the first plug member 23 and one second plug member 24.The outer wall of first mouth of pipe 210 of the inner tube 21 is consolidated with the inwall of the outer tube 20
Connect.The inside of second mouth of pipe 211 of the inner tube 21 sets a valve 25, to control communicating or closing for inner tube 21 and outer tube 20, this
Valve 25 is installed with a spring 250, and with pushing tow, the valve 25 is always maintained at closing strength the spring 250.
One striker 26, can be by control axial displacement.The striker 26 is interior by extending to this outside second mouth of pipe 201 of the outer tube 20
It is affixed with the valve 25 at second mouth of pipe 211 of pipe 21, can open valve 25 by the pushing tow striker 26.Tool one floats and lives
Plug 260, is arranged on the striker 26, and the floating piston 260 is located inside the outer tube 20, and positioned at second mouth of pipe of the outer tube 20
Between 201 and second mouth of pipe 211 of the inner tube 21, the inner area of outer tube 20 is separated with one first grease chamber by the floating piston 260
202 and an air chamber 203, first grease chamber 202 is communicated with the gap 22.
One piston rod 27, the piston rod 27 by the outer tube 20 the end of first mouth of pipe 200 via the inner tube 21 first mouth of pipe
210 extend to inside the inner tube 21.Has a piston 28, the piston 28 is fixedly arranged on the end of the piston rod 27 and positioned at the inner tube 21
Inside, with the displaced position of piston 28 as boundary, will separate one second grease chamber 212 and the 3rd grease chamber 213 inside the inner tube 21.Should
The inwall of inner tube 21 is provided with plurality of through holes 214, the through hole 214 adjacent to the end of first mouth of pipe 210 of the inner tube 21, by the through hole 214
The 3rd grease chamber 213 is made to be communicated with the gap 22 and first grease chamber 202.When valve 25 is opened, seat cushion can be adjusted
Displacement, and the piston rod 27 up or is down adjusted displacement with seat cushion, the piston 28 can be with the oil body in moveable cylinder 2C
Through valve 25 forward or reverse flow to do space hyperphoric；When valve 25 is blocked, the seat cushion position is to be fixed.
Have an elastomer 270 (as shown in Fig. 6 A, 6B, 6C), be set in outside the piston rod 27 (as shown in Figure 7 A), positioned at this
Between first mouth of pipe 210 of through hole 214 and the neighbouring inner tube 21, it is impossible to blocking via hole 214.The outer wall stage casing of the elastomer 270
With a groove 271 set with ring-type, having the elastomer 270 can be by compressibility.Shaft core position is provided with a perforation 272,
So that piston rod 27 is passed through；The top surface of the elastomer 270 and bottom surface be indivedual to be provided with one and pushes away and pull out inclined-plane 273, makes the elastomer 270
The tool elasticity of compression.
When bicycle is in normal temperature environment, the oil body in cylinder barrel 2C is compresses elastomeric 270 slightly, such as Fig. 7 and 7A
It is shown；When bicycle is in low temperature environment (such as snowfield), because of low temperature, volume is reduced the oil body in cylinder barrel 2C, cylinder barrel 2C
Internal cause oil body volume diminishes vacateed space, makes the elastomer 270 no longer be recovered to open shape by compression, such as Fig. 8 and 8A institutes
Show, to fill up the space that cylinder barrel 2C is vacateed, so that, even if opening valve 25 in low temperature environment, because of the space in cylinder barrel 2C
Filled up by elastomer 270, there will not be unnecessary oil body and enter in the 3rd grease chamber 213, cause bicycle to move to normal temperature environment
When opening valve 25 pressure become big, and the missing for being difficult to open the adjustment seat cushion of valve 25 is present.
The setting of the utility model elastomer, can fill up cylinder barrel inside oil body volume when low temperature environment and diminish what is vacateed
Space, even if opening valve, there will not be unnecessary oil body and enters in the 3rd grease chamber, improves known bicycle and moves to normal temperature environment
Afterwards, because the 3rd grease chamber oil mass increases, volume and pressure increase, and cause the stubborn missing of valve.Therefore the utility model has
Having can keep bicycle saddle cushion elevating adjusting device to use upper stability.
