Problems solved by technology

However, the existing pocketed helical spring row adopts a single seam structure (see Figure 1). After the cushion is formed, the row direction is easily elongated and deformed under the action of external force, so it will cause deformation after a period of use; Moreover, the pocketed helical spring row with a single seam structure is stressed because the seam is not a symmetrical structure, so it will cause the spring row to bend toward the seam (see figure 2 , image 3 ), affecting the quality of the upholstery
In addition, the bag body in the existing independent bagged spiral spring column is formed by a piece of cloth, and the scope of use is limited to a certain extent

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with accompanying drawing (embodiment):

[0015] refer to Figure 4 , The present invention includes a bag body 1 and a coil spring 2 . Each helical spring 2 is arranged side by side to form a helical spring row, and the bag body 1 is divided into two pieces of cloth, wrapped outside it, and forms two longitudinal seams 3, 4 consistent with the row direction, two seams 3, 4 are respectively located on the plane where the two ports of the cylinder of the coil spring 2 are located. Seams 3 and 4 can be welded, welded, sewn, glued and other processes. Due to the addition of a seam, the elongation and deformation of the spring row under the tension in the row direction can be effectively prevented; and because the two seams 3 and 4 are symmetrical structures, it can improve the spring row after being stressed in the row direction. In the deformed state, even if the force in the column directio...

Abstract

The invention discloses a double-joint independent bag-packed spiral spring row, which consists of bag body and spiral spring, wherein each spiral spring arranges side by side, with forms the spiral spring row; the bag body wraps the spiral spring row; the double-joint is formed on the row direction of spiral spring row upwards. The invention prevents the spring row from deforming, which changes the deformation state of row direction in the bed pad.

Description

technical field [0001] The invention relates to a spring row, in particular to a double seam type independent bagged spiral spring row. Background technique [0002] The existing independently bagged spiral spring columns are all wrapped with cloth. In order to make the produced mattresses, sofa cushions and other cushions softer and more comfortable, the materials used for the bag body are generally made of softer fabrics or non-woven fabrics. Elastic materials such as cloth have a certain elasticity under force. After the material forms a seam, it will form a different structure at the seam, making it hard and tough, and losing its original elasticity. However, the existing pocketed helical spring row adopts a single seam structure (see Figure 1). After the cushion is formed, the row direction is easily elongated and deformed under the action of external force, so it will cause deformation after a period of use; Moreover, the pocketed helical spring row with a single sea...
