Description
Technical field
The utility model relates to spring manufacturing technology field, especially a kind of reducing column type 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 forms complex structure by cylinder, piston (push rod), additional built-in spring etc.; Cooperate between part to require height, especially it is provided with piston respectively at a flexible cylindrical barrel upper and lower end, the middle cavity that forms; Realize Spring effect, but have airproof drawback up and down, when it is used for the mattress stage clip; Moisture in human body generation or the environment can be assembled in mattress surface; Can't get rid of through cross-ventilation, human body is being full of on the pneumatic spring mattress of moisture sleepingly, must impact healthy; 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, and the part complex manufacturing, and cost is higher.
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 vent ability is good, and the deformation stroke is long, the reducing column type gas spring that takes up room little after the compression.
The utility model is realized in the following manner: a kind of reducing column type gas spring; Comprise the spring body; Said spring body is formed by the cavity of a hollow at least, and the sidewall of said cavity is a multi-layer structure, all forms the chamber that holds pressed gas of sealing between each layer sidewall; It is cylindric that said cavity is the thick middle thin reducing in two ends, and each chamber all has vent.In this programme, gas spring hollow, full communication between the higher and lower levels property is good, is difficult for deposition moisture, avoids processing objects such as pad, seat with this gas spring because of gathering moisture health and product itself to be had a negative impact; Through the aeration quantity that vent is inflated or exhaust comes the real-time regulated chamber, thereby the hardness (elasticity) of regulating gas spring increases comfort level and Applicable scope; The gas spring sidewall is a multilayer, when being two-layer, forms a chamber, when being three layers, forms double-deck chamber arranged side by side, can set according to the load-bearing state; It is cylindric that the middle part cavity of said gas spring is the thin reducing in two short and thick centres, sees from its vertical cross-section, is recessed cydariform; And under inflated condition; Sidewall is the smooth flat of being with radian, and it is different from existing gas spring and only changes generation deformation with the flexibility of material itself, and adopts recessed drum organization to change the deformation stroke of cavity; It is big to have deformation, the advantage that the hardness regulation range is wide; When the pressure of gas spring receives top, this structure can evenly be disperseed pressure on gas spring, avoids causing the excessive overflexing of local compression impaired because of unbalance stress for a long time, effectively improves working life; It is little after chamber is got rid of the pressure air compression, to take up room, can package, and be convenient to packing, deposit and transport; The chamber post can be a monomer, also can in a row or become row to be shaped, and the chamber of each chamber post can independently also can be interconnected.
As preferably, have the air hole that several rows laterally run through chamber on the said cavity wall.In this programme, provide gas spring horizontal air convection channel, further increase its ventilatory effect, the design of air hole and hollow cavity has overcome the airtight problem of bringing of gas spring, has had the ventilation advantage of steel stage clip.
As preferably, the place of accent up and down of said cavity all is lined with the setting ring that can recover deformation, and said cavity madial wall path place be lined with one with the parallel stiffening ring of said setting ring.In this programme, the setting ring can also be hard elastic materials such as steel wire, 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; In addition,, effectively make each side producing balanced forces of cavity path section, prevent that one-sided bias voltage from causing unbalance stress and damaging raising gas spring compressive strength through stiffening ring is set.
As preferably, be opened on the said vent on the sidewall of said cavity, and be provided with air valve.In this programme, vent is located at is convenient on the sidewall connect tracheae and air valve, be convenient to make the equal may command air pressure of each gas spring intensity, avoid influencing comfort.
As preferably; Described cavity one deck sidewall is at least 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.In this programme, macromolecule organic material 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.
As preferably, described housing depth is 4-20cm, and bore is 4-8.5cm.In this programme, the too high then cavity of housing depth deformation stroke is long, and instability is crossed and hanged down then partially firmly, and comfort level reduces; The lining that bore then is laid on too greatly on the cavity can for want of support and partly be absorbed in, and forms pit, and too little then bottom surface reduces, and instability is prone to the pressurized swing.
As preferably, said spring external is enclosed with a soft ventilative outer cover.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.
As preferably, the place of accent up and down of said cavity all is lined with the hollow positioning plate.In this programme, through being set, positioning plate strengthens the gas spring anti-pressure ability, and platy structure helps improving the stability of gas spring vertical direction.
The beneficial effect of the utility model: adopt mode to realize that cavity is soft, hardness is adjustable to hollow cavity multilayer sidewall stowing pressure gas; Especially make its deformation stroke become big, the horizontal and vertical ventilated preferably that has; Both overcome metal spring perishable with defectives such as elastic force is non-adjustable; Also overcome the defective of piston (push rod) formula gas spring complex structure, vent ability difference; And the recessed drum type of inner arc wall is arranged instead through the structure of cavity, and make gas spring stressed evenly, obtain compressive strength preferably.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.
