Description
Technical field
The utility model relates to spring manufacturing technology field, especially a kind of gas column belt gas spring.
Background technique
" spring " can be divided into pressure spring, torsion spring and extension spring on function, pressure spring commonly used encloses around forming with the strong wire of elasticity such as steel wire twist, utilizes its elastic strain to produce elastic force.This type stage clip back elastic force that is shaped is set unadjustable, still occupies than large space after being compressed, and is used in to guarantee that each uses the zone all to have satisfied comfort level behind the place such as spring mattress.Though someone has designed gas spring, it is formed by inserting cylinder in the individual layer cavity, piston (push rod), additional built-in spring etc., and the spring body is made up of single chamber post; Compressive strength is low, and complex structure, cooperates between part to require height; In addition; Above-mentioned gas spring deformation stroke is not enough, and the hardness regulation range is little, and non-working condition still takies than large space.
The model utility content
The purpose of the utility model is for the deficiency that solves above-mentioned existing technology a kind of elasticity adjusting that has to be provided, and the deformation stroke is long, the gas column belt gas spring that takes up room little after the compression.
In order to achieve the above object; A kind of gas column belt gas spring that the utility model designed; Comprise the spring body; It is characterized in that described spring body is made up of many gas column bands with pressed gas receiving cavity, the two ends up and down of said many gas column bands connect positioning piece respectively, and the gas pressure in the said receiving cavity is adjustable.The technological scheme that the utility model limits is born support function by a plurality of gas column bands after locating piece connects, compare single chamber post, and compressive strength is high; But the hardness of real-time regulated gas spring (elasticity) increases comfort level and Applicable scope; Simple in structure, easy to process, it is convenient to assemble; The gas column band get rid of take up room after the pressure air compression little, can package, be convenient to packing, deposit and transport.
Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these characteristics:
Described gas column band is interconnected and has the vent that at least one is communicated with receiving cavity, and the gas pressure in each gas column band is unified to be regulated, convenient, fast, avoids simultaneously because the phenomenons such as one-sided inclination that gas spring air pressure inequality causes; Vent can be one, and exhaust is all operated through this vent with inflation, also can be two vents, an inflation, an exhaust.Each gas column band also can partly be communicated with or all not be communicated with, and separate receiving cavity passes through vent exhaust or inflation separately; Described many gas column bands vertically are provided with and leave each other horizontal and vertical gas-permeable channels; This just can increase the vertical rigidity of gas spring; Further strengthen the gas spring compression capability, and vent ability is good, is difficult for deposition moisture; Avoid spring to use at mattress, sofa, massage chair, fields such as cushion fashionable because of the moisture that gathers to health effects.
Described gas column interband is lined with the hard ring, prevents that one-sided bias voltage from causing the damage of unbalance stress, improves the whole compressive strength of gas spring.
Described locating piece is an air bag, and described gas column band is communicated with this air bag, makes the gas spring surface softness good, improves the travelling comfort that gas spring uses.
Described spring body is with outer cover, and in this programme, said outer cover can adopt the pocket of fabric, can become and the connection of adjacent gas spring is convenient in deformation with the spring bodily form, prevents adjacent sidewall bonding, interferes.
Be lined with the setting plate on the described locating piece or the ring that formalizes, in this programme, through setting plate or setting ring enhancing gas spring ability of anti-deformation are set, platy structure then helps improving the stability of gas spring vertical direction; The setting ring can also be hard elastic materials such as copper wire, plastic ring, and preferred steel wire because of its anti-deformation behavior is good, receives external force extruding back to be prone to restore to the original state, and supportive is good.
Described gas column band is vertical bar band shape or corrugated, and the vertical bar banded structure has the good advantage of supportive, and that wave structure has deformation is big, and the advantage that the hardness regulation range is wide can be decided according to the stressing property of user demand.
Described gas column brings to few one deck sidewall and is processed after compound by macromolecule organic material or itself and fabric, and described macromolecule organic material and fabric be compound to be meant that macromolecule organic material is filled in the hole of fabric or pastes in fabric one side.The macromolecule organic material here comprises rubber, TPU and/or nylon etc., adopts macromolecular materials such as rubber, can play the effect of sealing load gas, and can carry out mending-leakage through leakage compensating agent etc., improves ductility and sealing; Fabric then plays styling, makes gas spring after the pressure air filling, not produce the overdistension distortion, and makes the chamber wall have enough intensity.
Described many gas column band portions are communicated with; Part is independent or independent respectively; Be provided with the vent that is complementary separately; Described many gas column bands vertically are provided with and leave horizontal and vertical gas-permeable channels each other, and the gas pressure of gas spring different parts is regulated in the stressed distribution when using according to gas spring, can increase the gas pressure of the stressed larger part of gas spring.
Described spring height degree is 4-20cm, and it is long that too high then chamber cylindricality becomes stroke, and instability is crossed and hanged down then partially firmly, and comfort level reduces; Bore is 4-8.5cm, and the lining that then is laid on the post of chamber too greatly can be absorbed in from hollow space, forms pit, and too little then bottom surface reduces, and instability is prone to the pressurized swing.
A kind of gas column belt gas spring that the utility model obtains; Overcome metal spring perishable with defectives such as elastic force is non-adjustable; Single piston (push rod) formula gas spring complex structure, poor, the deformation stroke deficiency of vent ability have also been overcome, the defective that compressive strength is low; Regulate its soft, hardness through stowing pressure gas, especially have the good advantage of big, the horizontal and vertical ventilated of deformation stroke, be used to make mattress pad, sofa, massage chair, seat cushion etc., be easy to get rid of moisture, eliminate health effects; Hardness deformation range easy to adjust and unidirectional is big, satisfies the demand of all kinds of occasions, but real-time regulated also increases comfort level; And be convenient to package, save cost of transportation, the user is inflating expanded in use to get final product.
