Embodiment
See figures.1.and.2 the utility model sofa spring embodiment is described further.
A kind of sofa 2 use springs, comprise spring body 1, described spring body 1 is by spring thread spiral forming, described spring thread cross section periphery basic shape is circular, described spring body 1 includes supporting deformation portion 12 and the contraction deformation portion 13 of one winding, described spring silk dwindles coiling gradually by 13 one-tenth cross-section areas of supporting deformation portion 12 to contraction deformation portion, the spacing of any two adjacent spring threads of described contraction deformation portion 13 is less than the spacing of any two adjacent spring threads of supporting deformation portion 12, the spring thread external diameter of described supporting deformation portion 12 is less than the spring thread external diameter of contraction deformation portion 13.
The basic shape of spring body 1 is arranged to circle, be convenient for people to manufacturing, spring body 1 arranges supporting deformation portion 12 and after sofa 2 is interior, provides firm supporting effect for spring fitting, block body is heavy can allow because the deformation of supporting deformation portion 12 supports spring compression step by step after taking compared with large people, until just no longer deformation after mutually conflicting between each ring spring silk, arrange that contraction deformation portion 13 shrinks after being convenient for people to take and for people provide deformation power and cushion effect, seat on sofa 2 time sense of touch more comfortable, spring silk is dwindled to coiling gradually by 13 one-tenth cross-section areas of supporting deformation portion 12 to contraction deformation portion, so in the time that the spring that the application is installed is interior to sofa 2, supporting deformation portion 12 should be arranged on to the one side of people's seat dorsad, contraction deformation portion 13 is arranged on needs people's one side that directly contact is sat down, consider that supporting deformation portion 12 need to provide support power to the people who is sitting on sofa 2, so need the larger of cross-section area setting, make sofa 2 better firmly, and people are directly sitting in and need enough comfort levels and softness on sofa 2, so contraction deformation portion 13 little cross-section area is arranged to the one side towards people's seat, spring silk is more soft, take more comfortable, the cross-section area of whole piece spring silk presents the setting that gradually changes, the elastic force of spring body 1 can be changed according to born weight, meet the user's request of different weight, so sofa 2 furniture such as grade that sofa 2 use springs are made, there is good springiness, the advantage that comfort level is high.
Described spring thread all turns to smooth resistance surface 14 along the axial bi-side of helix, and smooth resistance surface 14 external diameters of supporting deformation portion 12 and smooth resistance surface 14 external diameters of contraction deformation portion 13 are suitable.When the stressed compressed rear adjacent spring thread of spring body 1 is in the time conflicting, the adjacent mutual butt of smooth resistance surface 14, can stably accept load, and suppresses spring thread along spiral slippage radially.
Described spring thread cross section periphery is cut apart two symmetry planes, and the cross section of this spring thread is formed two linearity ranges that are parallel to each other 141 and connected respectively the arcuate segment 142 of two linearity range 141 ends by two symmetry planes.Also with regard to being roughly, the sectional shape of spring thread is similar to the ellipse in four 100-metre dash roads, two symmetry planes are mainly that the end in order conveniently to make spring presents smooth plane, supporting deformation portion 12 arranges plane and makes spring body 1 be arranged on the placement that sofa 2 can be smooth when interior, be not easy, can effectively prevent from occurring depression position because of the unstable of supporting deformation portion 12 after sofa 2 from installing, contraction deformation portion 13 arranges plane and can make people be sitting in smooth plane, and comfort level is better.The plane of spring thread can first be processed into the columned steel wire of entirety, then, by section milling two planes of its two symmetry out, at the coiling machine by professional, its coiling is formed.
The helical spring central diameter at described spring body 1 two ends is larger.Spring body 1 two ends are larger, and area of contact is also larger, can adapt to large-area external load, also facilitate spring body 1 to be fixed on sofa 2.
