Abstract
The invention mainly discloses a gas spring which comprises a sleeve and a push rod, wherein the sleeve is of a cylindrical structure with a bottom but without cover; and one end of a movable type push rod extends into the sleeve and forms seal contact with the inner wall of the sleeve. The invention can realize elasticity by fully utilizing space and has the advantages of high elastic deformation degree and flexible and reliable gas adjustment.
Description
Technical field
The present invention relates to the spring technical field, special relevant with a kind of gas spring.
Background technique
Existing spring generally all is the elastic characteristic by elastic material, realizes elastic strain, and this elastic strain just utilizes the characteristic of material itself, and can't reach maximum compression.And after generally spring was made, its elasticity was just determined, can't regulate automatically as required again, and flexibility is not high.
Given this, the inventor designs a kind of gas spring, and this case produces thus.
Summary of the invention
Of the present inventionly mainly provide a kind of gas spring, can make full use of the space and realize elasticity, elastic strain degree height.
To achieve these goals, the technical solution used in the present invention is:
Gas spring comprises sleeve and push rod, and sleeve is the tubular structure that end uncovered is arranged, and one of packaged type push rod stretches into sleeve inner, forms sealing with sleeve lining and contacts.
Described push rod comprises upper bottom surface, bottom surface, links into an integrated entity with connecting shaft between two bottom surfaces.
A kind of gas spring mattress comprises base plate, some gas springs, backing plate, has the bottom plate hole that several supplied gas spring spools are set on the base plate, and backing plate is placed on the push rod, forms with the material coating outside base plate and the backing plate.
Described gas spring mattress, the bottom of all sleeves is communicated with by tracheae.
Described tracheae is provided with gas inlet and outlet.
After adopting such scheme, the spring among the present invention is can push rod compression sleeve gas inside, and the elastic strain of implementation space produces elastic force.Exist in the sleeve and have or not malicious innocuous gas, sleeve and push rod form the locking system that tightness is good.When push rod was not stressed, the gas in the sleeve was static, kept state of equilibrium.When push rod was subjected to external pressure, gas was compressed, and volume reduces, and it is big that air pressure becomes, up to reaching new balance.
The mattress of making by this gas spring, when bed body backing plate normal condition is not stressed, the pressure balance that the sleeve inner push-rod is subjected to up and down, sleeve keeps state of rest.When bed body backing plate was stressed, push rod was subjected to the effect of power and presses down, and gas is under pressure and smaller volume, and the air pressure of gas becomes greatly thereupon, and this process can last till till the pressure and external pressure balance of air pressure to push rod always.In addition, the cover tube bottom of whole mattress adopts tracheae that gas is communicated, and according to human body the bed body application of force is varied in size, and the gas compression of each sleeve inner is not of uniform size, forces gas flow, reaches new state of equilibrium.
In order to carry packaged convenience, the tracheae in the mattress is provided with a gas inlet and outlet simultaneously, and the gas of sleeve inner can be discharged outside the mattress, and push rod just can push sleeve inner, reduces the volume of mattress itself.And, in use,, use flexibility and reliability by the pressure size that gas inlet and outlet is regulated mattress gas.
Description of drawings
Fig. 1 is the structural representation of gas spring and base plate in the preferred embodiment of the present invention;
Fig. 2 is the schematic cross-section of preferred embodiment of the present invention;
Fig. 3 is the structural representation of tracheae in the preferred embodiment of the present invention.
Embodiment
As shown in Figure 1, gas spring mainly comprises sleeve 1 and push rod 2, and both formations are similar to the sealing configuration of cylinder and piston.
Present embodiment middle sleeve 1 is the cylindrical tube shape that end uncovered is arranged, and push rod 2 shapes are similar to I-shaped, comprises upper bottom surface 21, bottom surface 22 and middle 23, three parts of connecting shaft structure that links into an integrated entity.The shape of last bottom surface 21,22 is that the interior shape with sleeve 1 matches, and can form the sealing contact.Wherein bottom surface 22 extend into the inside of sleeve 1, and when sleeve 1 inside has under the situation of gas, upper bottom surface 21 exposes outside the sleeve 1, and it is stressed to be convenient to upper bottom surface 21 like this.
The mattress that adopts the above-mentioned gas spring to make except above-mentioned sleeve of mentioning 1 and push rod 2, also comprises base plate 3 and backing plate 4, as depicted in figs. 1 and 2.
Base plate 3 is main carriers of mattress, has some bottom plate holes of making according to sleeve 1 shape 31 on the plate body, and can be according to the mattress specification of reality and required elastic strengths and decide in the quantity of bottom plate hole 31 and position, is arranged to proper alignment usually.Each sleeve 1 all independently is embedded in the bottom plate hole 31, and push rod 2 is exposed at the top down at the tube end.Backing plate 4 is laid on the push rod 2, is withstood by push rod 2.Be coated with mattress fabric at base plate 3 and backing plate 4 outsides, form a mattress integral body.
As shown in Figure 3, in order to realize the flexible adjusting of mattress, be connected with tracheae 5 in the bottom of each sleeve 1, all tracheaes 5 all are connected together, and an input and output gas mouth 6 is set at last.When the air pressure of gas in the sleeve 1 does not meet demand, can suitably charge and discharge by input and output gas mouth 6, up to reaching required air pressure.When needs are carried, also can discharge gas outside the sleeve 1 from input and output gas mouth 6, push rod 2 just can be pushed into sleeve 1 inside fully, reduces the volume of mattress, dwindles transport space greatly.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
