The cross-sectional area of plug realizes the movement of piston rod to the pressure difference generated, and unlike mechanical spring, gas spring has
The elastic curve of near-linear.Performance is unstable in actual use for the gas spring of the prior art, is easily damaged, wants simultaneously
The machining accuracy asked is higher, the larger demand for not adapting to market of cost.
Chinese utility model patent, Authorization Notice No.: 203796836 U of CN, authorized announcement date: 2014.08.27, it is open
A kind of gas spring, including cylinder body, piston rod, button, bushing, guide sleeve, bowl-type rubber pad, piston valve and rear stifled, described is rear stifled
Positioned at the left end of cylinder body, the piston valve is located in cylinder body, and cylinder body is divided into two gas chambers in left and right, the piston valve and cylinder
Contact level is equipped with sealing element, and the middle part of sliding channel of piston valve is equipped with the venthole of vertical direction, during the piston rod is
Hollow structure, piston rod right output port inserted with button, button is club shaped structure, and groove is located at the right part of cylinder body, the bowl
Shape pad, guide sleeve and bushing are successively set on the right of groove.The structural elements of the utility model are more, requirement on machining accuracy
Height, assembling steps are more, inconvenient, and the components such as button therein, bushing belong to easily loss component, and influencing gas spring makes
Stability in limits the service life of gas spring, is unfavorable for promoting and applying in the market.
