Description
Technical field
The present invention relates to gas spring technology field, more particularly to a kind of gas compensating type gas spring.
Background technology
Gas spring, is a kind of using gas and liquid as the flexible member of working media, the mainly work in cylinder barrel, cylinder barrel
The composition such as plug and piston rod and guide sleeve.Storage has gas and part fluid in cylinder barrel, and the appearance in cylinder barrel is occupied due to piston
Product, during work in piston rod press-in cylinder barrel, piston axially moves the fluid in extrusion chamber in cylinder barrel, and fluid compressed gas
Body makes piston reach operating position.After the external force of loading on the piston rod disappears, then gas restores and expanded, the gas of expansion
Promote fluid to make piston reset, piston rod is removed, gas spring is realized compression motion and restore damped motion.
Gas spring has significant advantage than common spring：Speed slow, dynamic force change relatively is less (typically 1：
Within 1.2), be easily controlled.Have the disadvantage that relative volume does not have helical spring small, cost is high, the life-span is relatively short.Wherein expanding gas
Easily leakage, influences the life-span of gas spring after a long time use.
The content of the invention
The technical problem to be solved in the present invention is：Easily revealed to solve the expanding gas in cylinder barrel in the prior art
A kind of technical problem, gas compensating type gas spring can supply gas in the case of gas spring micro-leakage.
The technical solution adopted for the present invention to solve the technical problems is：A kind of gas compensating type gas spring, including cylinder barrel and work
Plug assembly, the piston component includes piston and piston rod, and piston is fixed on one end of piston rod, and cylinder is stretched into one end of piston rod
In cylinder and piston is located inside cylinder barrel, the cylinder barrel is double-decker, including internal layer and outer layer, piston are located in internal layer, internal layer
Formed to be provided with air inlet, air inlet on tonifying Qi chamber, outer layer between outer layer and air inlet mouthful seal is installed, the internal layer
On be further opened with gas supplementing opening, the rodless cavity of the gas supplementing opening connection tonifying Qi chamber and cylinder barrel, the gas compensating type gas spring also includes
Tonifying Qi mouthful seal, the section of the tonifying Qi mouthful seal in I-shaped, including the upper ring washer of integrative-structure, columnar supports with
And lower ring washer, upper ring washer and lower ring washer are respectively positioned at the two ends of columnar supports, and upper ring washer is connected in outer layer, cylindricality
Pole is located in tonifying Qi chamber and the outside diameter d 1 of columnar supports is slightly less than the internal diameter of gas supplementing opening, and the height h of columnar supports is slightly less than
The inwall of outer layer is to the inwall of internal layer apart from d2, and the external diameter of lower ring washer is more than the internal diameter of gas supplementing opening.Gas compensating type gas of the present invention
Gas in the tonifying Qi chamber of spring can only be flowed into rodless cavity, and because the external diameter of lower ring washer is more than in gas supplementing opening
Footpath, lower ring washer can cover gas supplementing opening, therefore, and the gas in rodless cavity cannot be introduced into tonifying Qi chamber.
Because the columnar supports of tonifying Qi mouthful seal are needed with certain elasticity, it could cause there is pressure in tonifying Qi chamber
At present ring washer opens gas supplementing opening, and the tonifying Qi mouthful seal is elastic sealing element.
In order to further improve sealing effectiveness, prevent the gas in rodless cavity from being revealed from gas supplementing opening into tonifying Qi chamber, institute
The outer ring for stating lower ring washer is in the circular arc of indent.
The beneficial effects of the invention are as follows, gas compensating type gas spring of the invention, by the way that cylinder barrel is designed into double-decker, increase
Tonifying Qi chamber, when gas that can be in rodless cavity is revealed on a small quantity, timely make-up gas strengthens the pressure of gas spring, it is ensured that
The normal of gas spring is used, so as to improve the service life of gas spring.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As Figure 1-4, it is optimum embodiment of the present invention, a kind of gas compensating type gas spring, including cylinder barrel 1 and piston component,
Piston component includes piston 2 and piston rod 3, and piston 2 is fixed on one end of piston rod 3, and one end of piston rod 3 is stretched into cylinder barrel 1
And piston 2 is located inside cylinder barrel 1, cylinder barrel 1 is double-decker, including internal layer 11 and outer layer 12, piston 2 are located in internal layer 11, interior
Formed to be provided with air inlet, air inlet on tonifying Qi chamber 13, outer layer 12 between layer 11 and outer layer 12 and air inlet sealing is installed
The rodless cavity 14 of gas supplementing opening 5, the connection tonifying Qi of gas supplementing opening 5 chamber 13 and cylinder barrel 1, gas compensating type gas bullet are further opened with part 4, internal layer 11
Spring also includes tonifying Qi mouthful seal 6, as shown in figure 4, the section of tonifying Qi mouthful seal 6 is in I-shaped, including integrative-structure is upper
Ring washer 61, columnar supports 62 and lower ring washer 63, upper ring washer 61 and lower ring washer 63 are respectively positioned at columnar supports 62
Two ends, the upper clamping of ring washer 61 is simultaneously fixed in outer layer 12, and it is interior and columnar supports 62 that columnar supports 62 are located at tonifying Qi chamber 13
Outside diameter d 1 is slightly less than the internal diameter of gas supplementing opening 5, in order to cause the gas in tonifying Qi chamber 13 to enter in rodless cavity 14, cylindricality branch
The height h of bar 62 is slightly less than the inwall of outer layer 12 to the inwall of internal layer 11 apart from d2, and the external diameter of lower ring washer 63 is more than tonifying Qi
The internal diameter of mouth 5.Tonifying Qi mouthful seal 6 is elastic sealing element.The outer ring of lower ring washer 63 is in the circular arc of indent.
As shown in figure 1, when the gas in rodless cavity 14 can normal work when, because the height h of columnar supports 62 is smaller
In outer layer 12 inwall to the inwall of internal layer 11 apart from d2, columnar supports 62 can hold lower ring washer 63, keep rodless cavity
Sealing between 14 and tonifying Qi chamber 13., can be by entering as shown in Fig. 2 when the micro leakage of the gas in rodless cavity 14
Gas port is inflated, and the gas in tonifying Qi chamber 13 enters in the gap between columnar supports 62 and gas supplementing opening 5, the lower ring washer 63 of compressing
Inwall away from internal layer 11 so that gas enters in rodless cavity 14, it is ensured that the gas in rodless cavity 14 is sufficient, meets gas spring
Condition of work.
