Abstract
The utility model discloses a high-strength mattress spring which is formed by winding a single-line-diameter alloy steel wire. Large spring circles are arranged at the upper, middle and lower layers of the spring. The high-strength mattress spring is characterized in that spiral-layer small spring circles are arranged between the large spring circles between the upper layer and the middle layer and between the large spring circles at the middle layer and the lower layer; the diameter ratio of the large spring circle and the small spring circle is equal to 1:0.6-0.7; the number of spiral layers is 4-6; and the large spring circle and the small spring circle are connected with one another by welding. As the large spring circle is arranged at the middle layer of the spring, the longitudinal stress area of the spring circle can be enlarged, and further the longitudinal stress of the spring is uniform, thereby avoiding the malposition and the deformation of the spring due to the overlarge longitudinal pressure on the spring by a human body. The high-strength mattress spring has a simple structure, is easy to implement, and can prolong the service life of a sofa.
Description
Technical field
The utility model relates to a kind of spring, particularly relates to a kind of high tenacity mattress spring.
Background technique
Chinese patent ZL200420083352.X discloses a kind of mattress and has used spring; Its overall structure is that the spiral layers lower end is big spring coil, and the upper end is little spring coil, and is tapered around shape; Basically solved owing to human body to the inequality of spring pressure and the irrecoverable problem on deformation of middle small spring ring that occurs; And the problem of Consumer's comfort, but its amount of elastic deformation is more obvious, and spring strength is also not high enough; Make spiral layers little spring coil in upper end and the big spring coil in lower end that permanent dislocation distortion, the working life of having reduced spring take place easily.
Summary of the invention
The purpose of the utility model is to overcome the strength deficiency of existing mattress spring, and a kind of high tenacity mattress spring of the moderate and difficult dislocation distortion of elasticity is provided.
The utility model is for solving this technical problem; The technological scheme of being taked is: a kind of high tenacity mattress spring; Be entwined by single line footpath alloy steel wire, the upper, middle and lower layer of spring is set to big spring coil, it is characterized in that: go up, the middle level and in, be equipped with the little spring coil of spiral layers between the big spring coil of lower floor; The diameter ratio of described big spring coil and little spring coil is 1: 0.6～0.7, and described spiral layers is 4～6 layers.
The height of described spring is 200～250mm, and diameter is the alloy steel wire of 1.5～2.5mm.
The diameter of described big spring coil is 80～95mm, and the diameter of the little spring coil of spiral layers is 45～50mm.
All adopt between described big spring coil and the little spring coil and be weldingly connected.
The beneficial effect of the utility model: alloy steel wire has the advantage of the high and good toughness of intensity, is well positioned to meet spring to the ability to bear under the different pressures situation.The utility model is taked in the spring middle level big spring coil to be set; Can increase spring ring lifting surface area longitudinally, make the spring longitudinal stress even, thereby overcome owing to human body causes the spring dislocation to be out of shape to the longitudinal pressure of spring is excessive; Working life easy to implement, as to have improved spring.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure, 1. big spring coil (), 2. little spring coil, 3. big spring coil (two), 4. big spring coil (three).
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be described in further detail.
Shown in accompanying drawing: a kind of high tenacity mattress spring; Be entwined by single line footpath alloy steel wire; The upper, middle and lower layer of spring is set to big spring coil; It is characterized in that: be equipped with the little spring coil 2 of spiral layers between the big spring coil in the big spring coil in upper strata () 1, the big spring coil (two) 3 in middle level and middle level (two) 3, the big spring coil (three) 4 of lower floor, the diameter ratio of described big spring coil and little spring coil is 1: 0.6, and described spiral layers is 5 layers.The height of described spring is 220mm, and diameter is the alloy steel wire of 2.0mm; The diameter of described big spring coil is 85mm, and the diameter of the little spring coil 2 of spiral layers is 46mm; All take to be weldingly connected between described big spring coil and the little spring coil 2.The utility model is simple in structure, and it is convenient to implement, and has overcome spring dislocation distortion, has prolonged the working life of sofa.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
Claims (4)
