Description
Technical field
The utility model relates to nitrogen spring technical field, relates in particular to a kind of bottom and has and fillThe nitrogen spring of gas.
Background technology
Known nitrogen spring is a kind of parts with spring function, and it seals high pressure nitrogenIn definite container, external force is compressed nitrogen by plunger rod, leans on high pressure in the time that external force is removedNitrogen expansion obtains certain elastic force pressure, and this parts are called nitrogen cylinder or gas spring, letterClaim nitrogen spring. Existing nitrogen spring is all made up of cylinder body, plunger rod and upper end cover, cylinderBody and plunger rod are formed with the cavity of nitrogen, general on cylinder body, have a nitrogen inflation inlet, butThat existing nitrogen spring all exists following defect: the first, the cylinder body of existing nitrogen springOn be provided with nitrogen inflation inlet, but nitrogen inflation inlet is all by by the nitrogen inflation on cylinder bodyMouth is opened, and because nitrogen inflation inlet is connected with the cavity of nitrogen, thereby makes in cavity remainingNitrogen just may discharge by nitrogen inflation inlet, will cause like this waste of resource; The second,Existing nitrogen spring design is reasonable not, makes sealing property poor, can not meet peopleUser demand; The 3rd, between existing cylinder body and plunger rod, be provided with upper end cover, structure isComplexity, is unfavorable for installing, and has increased the difficulty of installing.
Utility model content
For deficiency of the prior art, the utility model provides a kind of bottom to have inflationNitrogen spring.
To achieve these goals, technical solution adopted in the utility model is:
Bottom has a nitrogen spring for inflation, comprises cylinder body and plunger rod, and cylinder body is emptyThe cylinder of the heart, the inside of cylinder body lower end is provided with bottom, and cylinder upper end face is provided with plunger rod,Cylinder body and bottom, plunger rod are formed with the cavity of nitrogen, and the bottom of cavity contacts and establishes with bottomBe equipped with anti-wear lubricating oil reservoir, have fill opening on bottom, fill opening is connected with cavity,Fill opening inside is provided with charge valve, and the fill opening inwall of charge valve bottom is provided with interior spiral shellLine, the internal thread fill opening of charge valve bottom is provided with nut.
Between described plunger rod and inboard wall of cylinder block, under upper, be disposed with dust ring one, resistance toGuide ring and the y-type seal ring of mill, described dust ring one has wear-resisting functions.
Between described bottom and inboard wall of cylinder block, be disposed with from top to bottom O type circle, steel wire gearCircle and dust ring two.
Described plunger rod upper surface is provided with the screwed hole of maintenance.
The beneficial effects of the utility model: compared with prior art, the utility model cylinder body isHollow cylinder, the inside of cylinder body lower end is provided with bottom, and cylinder upper end face is provided with plungerBar, cylinder body and bottom, plunger rod are formed with the cavity of nitrogen, and it is reasonable in design, simple in structure,Thereby be convenient to install and manufacture; The bottom of cavity contacts and is provided with wearproof lubricant with bottomLayer, has fill opening on bottom, fill opening is connected with cavity, the inner peace of fill openingCharge valve is housed, and the fill opening inwall of charge valve bottom is provided with internal thread, charge valve bottomInternal thread fill opening be provided with nut, thereby make the nut of nitrogen inflation inlet open itAfter, the residue nitrogen in cavity also can not run out of automatically, thereby makes to have avoided waste resource,Save resource, protected environment; Between described plunger rod and inboard wall of cylinder block under upper successivelyBe provided with dust ring one, wear-resisting guide ring and y-type seal ring, described bottom and inboard wall of cylinder blockBetween be disposed with from top to bottom O type circle, elastic spring and dust ring two, thereby greatly carryHigh sealing property, can meet people's user demand more.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of bottom has the nitrogen spring of inflation, comprises cylinder body 1 and postStopper rod 2, cylinder body 1 is hollow cylinder, the inside of cylinder body 1 lower end is provided with bottom 3,Between described bottom 3 and cylinder body 1 inwall, be disposed with from top to bottom O type circle 11, steel wireBack-up ring 12 and dust ring 2 13, cylinder body 1 upper surface is provided with plunger rod 2, described plunger rod2 and cylinder body 1 inwall between from being disposed with dust ring 1, wear-resisting guide ring under upper22 and y-type seal ring 23, described dust ring 1 has wear-resisting functions, cylinder body 1 and the endLid 3, plunger rod 2 are formed with the cavity 4 of nitrogen, and the bottom of cavity 4 contacts with bottom 3Be provided with anti-wear lubricating oil reservoir 41, on bottom 3, have fill opening 31, fill opening 31 withCavity 4 is connected, and fill opening 31 inside are provided with charge valve 32, charge valve 32 bottomsFill opening 31 inwalls be provided with internal thread 33, the inflation of the internal thread of charge valve 32 bottomsOpening is provided with nut, and described plunger rod 2 upper surfaces are provided with the screwed hole 24 of maintenance.
The utility model is first only used the nut of fill opening 31 is opened in the process using,And in cavity 4, also have nitrogen, because fill opening 31 inside are provided with charge valve 32, therebyNitrogen in cavity 4 can not discharged to some extent along with opening of nut, be conducive to save moneySource and protection of the environment, and after external equipment and fill opening 31 connections, just can carry outInflated with nitrogen, after inflation finishes, has been full of nitrogen 5 in cavity 4, only fill with pulling out outsideGas is established, and in cavity 4, instinct nitrogen 5 also can not be run out of simultaneously, thereby has saved resource,Then by fill opening on nut cap 31.
The beneficial effects of the utility model: compared with prior art, the utility model cylinder body isHollow cylinder, the inside of cylinder body lower end is provided with bottom, and cylinder upper end face is provided with plungerBar, cylinder body and bottom, plunger rod are formed with the cavity of nitrogen, and it is reasonable in design, simple in structure,Thereby be convenient to install and manufacture; The bottom of cavity contacts and is provided with wearproof lubricant with bottomLayer, has fill opening on bottom, fill opening is connected with cavity, the inner peace of fill openingCharge valve is housed, and the fill opening inwall of charge valve bottom is provided with internal thread, charge valve bottomInternal thread fill opening be provided with nut, thereby make the nut of nitrogen inflation inlet open itAfter, the residue nitrogen in cavity also can not run out of automatically, thereby makes to have avoided waste resource,Save resource, protected environment; Between described plunger rod and inboard wall of cylinder block under upper successivelyBe provided with dust ring one, wear-resisting guide ring and y-type seal ring, described bottom and inboard wall of cylinder blockBetween be disposed with from top to bottom O type circle, elastic spring and dust ring two, thereby greatly carryHigh sealing property, can meet people's user demand more.
