Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the breakage-proof pocketed honeycomb structure spring includes a spring unit 1, the spring unit 1 includes a non-woven fabric unit 20 and a concave spiral spring 3 wrapped inside the non-woven fabric unit 20, and the spring unit 1 is arranged in a one-to-one manner to form a spring layer.

In this embodiment, the spring assembly may be used as a mattress, a sofa cushion or other living soft cushion, and the soft cushion may have a planar structure such as a bed board or the ground as a supporting surface.

In this embodiment, use the non-woven fabrics that appear on the market as the material of spring bagged structure, like organic macromolecular material such as high density polyethylene fibre, this kind of macromolecular material is corrosion-resistant, and the fibre bits of cloth grinds the rate of taking off low, and the fibre tearing degree is low, can not torn by the spring under the motion state, and is favorable to the fungi-proofing anti-mite, and the gas permeability is good, can exhaust fast and hydrofuge in the sleep process.

As shown in fig. 1 and 2, each nonwoven fabric unit 20 is a rectangular parallelepiped structure, and regular hexagonal fabric pieces 21 are sealed at the edges of the upper and lower surfaces, each nonwoven fabric unit 20 includes two wide side surfaces 22 and two long side surfaces 23 with the area twice as large as the wide side surfaces, each two nonwoven fabric units 20 in the same row share one wide side surface 22, each row of long side surfaces is one-half of the front and rear long side surfaces, and the wide side surface 22 is connected to the central axis of the front and rear long side surfaces 23 in the same row.

In this embodiment, the nonwoven fabric is formed into a sealed environment by the action of heat and pressure, wherein the individual nonwoven fabric units 20 are closely arranged in a cross-over arrangement, without the need for adhesives and fillers.

As shown in fig. 1, 2 and 3, when opposite forces are applied to the central axes of the front and rear long side surfaces 23, the long side surfaces 23 are deformed by the forces, and the nonwoven fabric unit 20 is changed into a honeycomb structure.

In the present embodiment, the non-woven fabric unit is in a rectangular parallelepiped shape in the initial state, and the long side 23 can be stretched, as shown in fig. 3, and changed to a honeycomb structure, the area of the spring unit is increased, and the entire area of the whole breakage-proof pocketed honeycomb-structure spring is increased at the same time.

In this embodiment, as shown in fig. 1, the spiral diameter of the concave-convex spiral spring 3 gradually decreases from top to bottom and then gradually increases, the bottom end and the top end of the concave-convex spiral spring 3 are respectively provided with a wire loop 4, and the wire loop 4 is welded to two ends of the spring.

When the spring received pressure and the type becomes, the iron wire that its both ends were exposed easily torn bagged structure, caused bagged structure's damage, fixed the iron wire at both ends on iron wire circle 4 with the welded mode in this embodiment, reduced and pulled the local pressure that in-process bagged structure need bear, reduced the loss.

As shown in fig. 1, elastic threads 24 are disposed between four corners of the top layer and four corners of the bottom layer of the nonwoven fabric unit 20, and the elastic threads 24 penetrate the concave coil spring 3 from top to bottom. The present embodiment provides the elastic thread 24 to fix the concave-shaped coil spring 3 in the vertical direction, and prevents the spring from swaying or even tilting from side to side in the relatively large-space nonwoven fabric unit 20 when the spring jumps.

Through the breakage-proof pocket honeycomb structure spring of the present embodiment, wherein the non-woven fabrics are connected into a cross and closely arranged rectangular structure by means of hot pressing, the regular hexagonal fabric pieces 21 are connected to the lower bottom edge of each non-woven fabric unit by hot pressing, the spring is put into each non-woven fabric, the regular hexagonal fabric pieces 21 are connected to the top edge of the non-woven fabric unit 20 by hot pressing and sealing, and finally the pocket-sealed spring unit 1 is formed with the upper and lower surfaces contracted inward.

In addition, in practical application, the breakage-proof pocket springs of the present embodiment are pulled in the direction perpendicular to the long side surfaces, the upper and lower surfaces of the pocket springs are changed from rectangular to honeycomb by force, and the size of the entire area is changed to adapt to mattress supports of different areas.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
