Description

Technical Field

[0001] The utility model relates to the technical field of furniture accessories, in particular to a spring and a spring bed net. Background Art

[0002] At present, Bonnier spring is one of the most common types of springs used in the manufacture of mattresses or cushions. It is a spring with large upper and lower port diameters, small middle diameter, and end-face knotted winding. It has the characteristics of strong elasticity, excellent vertical support performance, and relatively high hardness.

[0003] Existing Bonnier spring bed nets are all made by connecting Bonnier springs together in a row, so that the Bonnier springs can extend in a spring core in a row or column, and are connected by twisting or winding a plurality of spring strips. However, there is a disadvantage that, limited by the curvature of the current Bonnier spring, the number of windings between the spring strip and the Bonnier spring is only two. When a heavy person sits down or sleeps, the supporting force is insufficient, which will affect the performance of the spring in the long run; therefore, improvements should be made.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spring, comprising a spring body, wherein the spring body comprises a spiral coil in the middle section and end coils arranged at both ends of the spiral coil, wherein the ends of the end coils are wound between the spiral coil and the end coils, wherein the left and right sides of the end coils are symmetrically provided with crossing parts, wherein the crossing parts are arranged in a direction away from the compression direction of the spiral coil, the crossing parts are in an outer arc-shaped structure relative to the spiral coil, the arc radius is 10-12mm, and the two ends of the crossing parts are connected to the end coils through a retracted part.

[0006] Furthermore, the diameter of the end coil is larger than that of the spiral coil.

[0007] Furthermore, the number of winding turns of the end coil is at least 2 turns.

[0008] A spring bed net comprises the above-mentioned spring body, wherein the spring bed net is composed of a plurality of laterally distributed spring rows, and spring bars are arranged between adjacent spring rows, the spring rows are composed of a plurality of spring bodies distributed along the longitudinal direction, the crossing portion on the left side of one spring body is staggered with the crossing portion on the right side of another spring body, and the spring bars are wound and fixed to connect the two laterally adjacent spring rows.

[0009] Furthermore, the number of winding turns between the spring bar and the through portion is at least 4 turns.

[0010] Furthermore, a frame is included, the frame is a rectangular structure, and the frame is connected to the end coil of the spring body through a fixing sleeve.

[0011] Compared with the prior art, the beneficial effects of the utility model include: end coils are provided at both ends of the spring body, and through-parts are symmetrically provided on the left and right sides of the end coils, the through-parts are located away from the compression direction of the spiral coil and have an outer arc structure with an arc radius of 10-12mm. When multiple spring bodies are combined to form a spring bed net, adjacent spring bodies are wound and fixed by spring strips, so that the spring strips can be wound on the through-parts for at least 4 turns.
