Description
Technical field
The utility model relates to spring manufacturing technology field, especially a kind of gas spring of elasticity adjusting.
Background technique
" spring " can be divided into pressure spring, torsion spring and extension spring on function, pressure spring commonly used with the strong wire of elasticity such as steel wire enclose twist around, utilize 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 influences comfort level after being used in place such as spring mattress.Though someone has designed gas spring, it is made up of cylinder, piston (push rod), additional built-in spring etc., and complex structure cooperates between part to require highly, and the deformation stroke is not enough, and the hardness regulation range is little.
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 spring of the little elasticity adjusting that takes up room after the compression.
In order to achieve the above object; The gas spring of a kind of elasticity adjusting that the utility model designed; Comprise the spring body; It is characterized in that described spring body is formed by at least one chamber post, form the chamber that holds pressed gas of sealing in the post of described chamber, described chamber post is corrugated and has the vent that at least one is communicated with chamber.The technological scheme that the utility model limits can be one-body molded, and is easy to process; Also can increase comfort level and Applicable scope through the hardness that vent is inflated or exhaust comes the real-time regulated gas spring; Chamber get rid of take up room after the pressure air compression little, can package, be convenient to packing, deposit and transport.The outer wall of chamber post can be a lineal shape, also can be corrugated.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.
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 chamber post is corrugated; The bellows chamber post is meant that the chamber post jamb is not a straight line; Straight line that is folded to repeatedly inside and outside being or curved side, it is different from existing gas spring and only changes generation deformation with the flexibility of material itself, and adopts corrugated structural deformation to change the deformation stroke of chamber post; It is big to have deformation, the advantage that the hardness regulation range is wide.
The chamber wall of said chamber post 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, and can carry out mending-leakage through leakage compensating agent etc., improves ductility and sealing; Fabric plays styling, makes gas spring after the pressure air filling, not produce the overdistension distortion, and makes the chamber wall have enough intensity.
At least be provided with the ring segment of a band planarea on the post of described chamber; Described planarea constitutes junction surface, and junction surface is used for bonding between adjacent vacant air spring monomer, and it is cross equispaced on ring segment that junction surface can be; Make that a plurality of directions of chamber post all can bonding other monomers, favorable expandability.
Have the air hole that runs through chamber on the described ring segment, be used for the horizontal cross-ventilation of gas spring, be difficult for deposition moisture, avoid spring to use at mattress, sofa, fields such as cushion fashionable because of the moisture that gathers to health effects.
Described ring segment cross section is the Octagon by length limit articulating successively of symmetry, and described planarea lays respectively at octagonal four minor face places, the neat unification of junction surface, and cementability is good.
Bellows segment upper and lower end in the middle of the post of described chamber forms the ring segment of outside hole enlargement, the outer distolateral chamber post upper and lower opening of said ring segment with undergauge, and promptly chamber post upper and lower end bore is less than ring segment; To form independent support; Reduce the chamber intercolumniation and pull deformation mutually, the phase mutual interference is little, and avoids forming depression; More press close to human body contour outline, increase comfort level; The little place of middle bore can be installs the tracheae slot milling, also helps the lateral flow of air.
Post upper and lower opening place, described chamber is lined with the setting ring of processing with steel wire, and the setting ring can also be hardness 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 vent is opened on the interior flanging of ring segment and is provided with air valve, and the spring body caves inward here, and the space is big, is convenient to install.
The cross section of said chamber post is circle or polygonal, further satisfies the requirement in hardness, air pressure spring distribution density, ventilatory effect, the material selection from sectional shape.
The gas spring of a kind of elasticity adjusting that the utility model obtains; 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, changed the structure shape of chamber post; Utilize the wave structure of similar Accordion qin case; Regulate its soft, hardness through stowing pressure gas, especially have the advantage that deformation stroke is big, transversal ventilation property is good, 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.
