Such as Fig. 7：Piston sheet 15 is chrysanthemum flap-type structure, and piston sheet 15 includes the body and circle being sleeved on piston rod 2
The chrysanthemum flap-type blade 16 of the odd number on body, the slitting between adjacent chrysanthemum flap-type blade 16 of air passing hole 11 is arranged in all arrays
Mouth straight slot.
Such as Fig. 8：Piston sheet 15 includes the body being sleeved on piston rod 2, and circumference array is provided with odd number on body
Arc-shaped slot 17.
The more penetrating smoothness of above two structure, preferably 5 fulcrum chrysanthemum piston sheets or big straight slot metallic piston piece.Five fulcrums
Chrysanthemum piston sheet, five fulcrums of plum blossom piston improve piston rod 2 and piston component 5 and cylinder body 3 and pilot seal component 4
Concentricity keeps gas spring operation more steady.
2 right end of piston rod is connected with front connector 1.
Pilot seal component 4 is provided in the right end endoporus of cylinder body 3, pilot seal component 4 and the right end of cylinder body 3 close up
Press setting.
Block up 7 afterwards uses sealing welding, sealing tight with the connection of cylinder body 3.
As preferably such as Fig. 5-6：Block up afterwards 7 and the connection of cylinder body 3 be to be pressed using filling after (note) gas to close up, block up on 7 increase afterwards
Add 2 O-ring seals 13, rear stifled 7 and cylinder body 3 when being separated, high pressure sealing is carried out to empty cylinder body and fills (note) gas, thus
Ensure consistent gas injection rate, improves the accurate requirement of gas spring force value, in cylinder body gas injection complete moment, high-pressure gas injection device
Closing-in mould is blocked up in 7 push-in cylinder bodies 3 after and is closed up simultaneously.
Use secondary no means of press seals, no means of press seals does not have air pressure (pressure), reason when referring to starting between 2 sealing elements
It is inflation while closes up, double containment compression gas spring is using to 3 tail portion cavity gas injection of cylinder body, first sealing element (rear sealing
13) circle has blocked passing through for air pressure, for second sealing element (rear sealing ring 13) because not being pressurized, it generates very little to piston rod
Frictional force is negligible, with the stretching motion of gas spring, the reasonable product with oil mass of the piston rod surface generation of gas spring
It is tired, pressure gradually just is generated to second sealing element lip, which improves 4 sealing performance of pilot seal component and uses the longevity
Fate.
In the figure 7, the damping oil 9 of occupy-place occupies the space of gas volume, and Bing plays the role of flow damping, can press design
The pressure ratio for needing effectively raising gas spring realizes the maximum bearing pressure of gas spring with the mesh of the close balance of mattress gravity.
We describe the application structural principle and component differences, block up 7, pilot seal system 4, piston component 5, occupy-place afterwards
Damping oil 9 this design concept and the present invention general idea application theory, be all our ranges to be laid special stress on protecting.
Reasonable design of the present invention, it is of low cost, durable, safe and reliable, easy to operate, time saving and energy saving, save fund,
It is compact-sized and easy to use.
It is to be disclosed in order to more clear, and just do not illustrating one by one for the prior art that the present invention, which fully describes,.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
