Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to the mesh assembly in a spring pad. Background Technology

[0002] The mesh used in spring mattresses generally refers to a type of elastic fabric or mesh structure material used to connect and fix springs, or to act as a support layer / cushioning layer, in cushions or mattresses equipped with spring support systems.

[0003] It plays a key role in enhancing the comfort, breathability, durability, and structural stability of seat cushions.

[0004] Currently used mesh is mostly grid-like steel wire mesh. While this type of mesh has high strength, its cushioning performance is limited. Furthermore, because the longitudinal and transverse steel wires in the mesh are in direct, rigid contact, the friction between the wires during use generates noise, which in turn affects the comfort of the cushion or mattress. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a mesh assembly in a spring pad.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0007] A mesh assembly in a spring pad includes a first steel wire arranged laterally and a second steel wire arranged longitudinally. It is characterized by further including a connecting tube and a covering layer located outside the first steel wire. There are two first steel wires arranged parallel to each other. Several second steel wires are vertically connected between the two first steel wires and are evenly distributed along the length of the first steel wires. The covering layer is tightly pressed between the first and second steel wires. The connecting tube is parallel to the first steel wire, and several second steel wires are threaded and connected to the connecting tube.

[0008] In the mesh assembly of the aforementioned spring pad, the connecting tube is a flexible tube, and there are several connecting tubes, which are evenly distributed between two steel wires.

[0009] In the mesh assembly of the aforementioned spring pad, the covering layer is a polypropylene layer covering the outside of the steel wire.

[0010] In the mesh assembly of the aforementioned spring pad, the covering layer is a polyethylene layer covering the outside of the steel wire.

[0011] In the mesh assembly of the aforementioned spring pad, the inner diameter of the connecting tube is larger than the outer diameter of the steel wire.

[0012] In the mesh assembly of the aforementioned spring pad, the two ends of the steel wire have a spirally wound connecting portion and the connecting portion is sleeved on the first steel wire.

[0013] In the mesh assembly of the aforementioned spring pad, some of the connecting parts of the second steel wire have a relief portion that bends inward toward the entire mesh assembly, while other connecting parts of the second steel wire have a hook that protrudes outward toward the entire mesh assembly.

[0014] In the mesh assembly of the spring pad described above, along the length of the first wire, the second wire with a clearance portion and the second wire with a hook are arranged alternately and adjacently.

[0015] In the mesh assembly of the aforementioned spring pad, the midpoint of the line connecting the upper and lower parts of the connecting portion is the reference position, and the outer end of the aforementioned clearance portion is located at the reference position.

[0016] In the mesh assembly of the aforementioned spring pad, the number of turns in the connecting portion is 1.5 to 4 turns.

[0017] Compared with existing technologies, in the mesh assembly of this spring pad, the covering layer prevents steel wire one and steel wire two from forming a rigid connection; at the same time, the connecting tube ensures that two adjacent steel wires maintain a set distance. Therefore, when the entire mesh assembly is subjected to external force, steel wire one and steel wire two will not make direct rigid contact, resulting in less noise when under force and effectively improving the user comfort of the corresponding elastic pad.

[0018] In addition, during use, several connecting pipes connect several steel wires, so that the entire mesh assembly can not only provide stable support, but also maintain the same strength in all parts of the mesh assembly, which has high practical value. Attached Figure Description

[0025] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0026] like Figure 1-2 As shown, the mesh assembly in this spring pad includes a horizontally arranged steel wire 1 and a longitudinally arranged steel wire 2, as well as a connecting tube 3 and a covering layer 4 located outside the steel wire 1. There are two steel wires 1 arranged in parallel. The steel wires 2 are vertically connected between the two steel wires 1 and there are several steel wires 2. The several steel wires 2 are evenly distributed along the length of the steel wires 1. The covering layer 4 is tightly pressed between the steel wires 1 and the steel wires 2. The connecting tube 3 is arranged in parallel with the steel wires 1, and the several steel wires 2 are all threaded and connected to the connecting tube 3.

[0027] The connecting pipe 3 is a flexible tube, and there are several connecting pipes 3, which are evenly distributed between two steel wires 1.

[0028] Since the outer side of steel wire 1 is wrapped with a coating layer 4, and the coating layer 4 is made of a flexible material, the rigid contact between steel wire 1 and steel wire 2 can be avoided under the action of the coating layer 4.

[0029] In this embodiment, the connecting pipe 3 is made of polyethylene. Of course, depending on the actual situation, it is also feasible to use polypropylene for the connecting pipe 3.

[0030] Given that several connecting tubes 3 are evenly distributed between two steel wires 1, and steel wires 2 pass through and connect to each connecting tube 3, in other words, several connecting tubes 3 are evenly distributed along the length of all steel wires 2. Under the action of the connecting tubes 3, the steel wires 2 can maintain a set spacing, and the flexible connecting tubes 3 can further enhance the buffering performance of the entire mesh assembly.

[0031] The coating layer 4 is a polypropylene layer covering the outside of the steel wire 1. Depending on the actual situation, it is also feasible to use a polyethylene layer covering the outside of the steel wire 1 as the coating layer 4.

[0032] Regardless of whether the covering layer 4 is made of polypropylene or polyethylene, rigid contact at the connection between steel wire 1 and steel wire 2 can be avoided.

[0033] The inner diameter of the connecting pipe 3 is larger than the outer diameter of the steel wire 1.

[0034] This structure not only ensures that the entire mesh assembly has sufficient buffering performance, but also allows the steel wire 2 to be stably threaded and connected to the connecting pipe 3.

[0035] The end of the second steel wire has a spirally wound connecting part 21, and the connecting part 21 is sleeved on the first steel wire 1.

[0036] The connecting part 21 can increase the contact area at the connection between steel wire 1 and steel wire 2, thereby improving the connection stability between steel wire 1 and steel wire 2.

[0037] Some of the connecting parts 21 of the steel wire 2 have a relief part 211 that bends inward toward the inside of the whole mesh assembly, while other parts of the connecting parts 21 of the steel wire 2 have a hook 212 that protrudes outward toward the outside of the whole mesh assembly.

[0038] Since the clearance part 211 is located inside the mesh assembly, the arrangement of the clearance part 211 can prevent the end of the steel wire 2 from occupying too much space on the outside of the entire mesh assembly.

[0039] The hook 212 allows the mesh assembly to be stably connected to its matching frame.

[0040] Along the length of the first wire 1, the second wire 2 with the avoidance part 211 and the second wire 2 with the hook 212 are arranged alternately and adjacently.

[0041] This improves the structural compactness of the entire mesh assembly.

[0042] The midpoint of the line connecting the upper and lower parts of the connecting part 21 is the reference position, and the outer end of the avoidance part 211 is located at the reference position.

[0043] This structure prevents the avoidance part 211 from protruding from the upper or lower part of the entire mesh assembly.

[0044] The number of turns of the connecting part 21 is 1.5 to 4 turns.

[0045] This range of turns ensures a stable connection between wire 1 and wire 2.

[0046] In the mesh assembly of this spring pad, the covering layer 4 prevents steel wire 1 and steel wire 2 from forming a rigid connection; at the same time, the connecting tube 3 ensures that two adjacent steel wires 2 maintain a set distance. Therefore, when the entire mesh assembly is subjected to external force, steel wire 1 and steel wire 2 will not make direct rigid contact, resulting in less noise when under force and effectively improving the comfort of using the corresponding elastic pad.

[0047] In addition, during use, several connecting pipes 3 connect several steel wires 2 together, so that the entire mesh assembly can not only provide stable support, but also maintain the same strength in all parts of the mesh assembly, which has high practical value.

[0048] This mesh assembly is suitable for sofas, chairs, swivel chairs, and mattresses.

[0049] like Figure 3 and Figure 4 As shown, in this scheme, the ends of the steel wire 2 in the mesh assembly of the spring pad do not have hooks 212, and all ends of the steel wire 2 are clearance parts 211.

[0050] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0051] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
