Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a novel four-core spring for a mattress. Background Art

[0002] A mattress is an item that is placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep. Mattresses include spring mattresses, memory foam mattresses, latex mattresses and other types. Spring mattresses generally have springs installed inside the mattress, making the mattress elastic and supportive.

[0003] The springs used in existing mattresses are generally formed by spirally winding a single elastic metal wire. During use, the spring's own supporting performance is poor. When subjected to excessive force, it will cause deformation and collapse. In addition, the contact area between the two ends of the spring and the mattress is small, which can easily damage the mattress and hurt the user. Moreover, because the spring is exposed inside the mattress, the spring itself will come into contact with the air inside the mattress. The oxygen in the air will oxidize and rust the spring surface, resulting in poor performance. Therefore, we propose a new four-core spring for mattresses. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a new type of four-core spring for a mattress.

[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a novel four-core spring for a mattress is designed, comprising four elastic metal wires, which form a spring core wire, the spring core wire being arranged in a spiral shape, and the spring core wire including a second support section arranged in the middle and first support sections arranged at both ends;

DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Reference Figures 1-4 A new type of four-core spring for a mattress includes four elastic metal wires 6, which form a spring core wire 7. The spring core wire 7 is spirally arranged, and the spring core wire 7 includes a second support segment 11 arranged in the middle and a first support segment 10 arranged at both ends. The diameter of the second support segment 11 is larger than the diameter of the first support segment 10, which can increase the load capacity and greater elastic deformation of the spring, extend the service life of the spring, and will not lose elasticity due to excessive pressure during use.

[0024] like Figure 1 and Figure 2 As shown, the utility model also includes two support pads 1, the spring core wire 7 is located between the two support pads 1, and a first connecting block 2 is vertically installed at one end of each first support segment 10, and a first strip connecting plate 3 is provided along the bottom side of each first connecting block 2, and a second connecting block 4 is installed at both ends of each support pad 1, and the first strip connecting plate 3 is arranged under the corresponding second connecting block 4, and a second strip connecting plate 5 is extended to one side of the bottom of each second connecting block 4, and the second strip connecting plate 5 is fastened to the corresponding first strip connecting plate 3 by bolts or welding, so that the support pad 1 can be connected to the first support segment 10, which can increase the contact area between the spring end and the mattress and improve the support effect.

[0025] It should be noted that each support pad 1 is flush with the end of the corresponding first support section 10. In this way, when in use, under the action of the support pad 1, the contact area between the spring end and the mattress remains stable and will not hurt the user.

[0026] like Figure 3 and Figure 4 As shown, a first protective cover 8 is installed on the outer surface of each elastic metal wire 6. The first protective cover 8 is made of a sealing rubber material, or other sealing materials with deformation properties. Under the action of the first protective cover 8, the elastic metal wire 6 can be separated from the external environment. In this way, during actual use, the elastic metal wire 6 will not be oxidized and rusted by oxygen in the external air, thereby improving the protection effect.

[0027] It should be noted that the outer surface of each elastic metal wire 6 is provided with a chrome plating layer 13. In actual use, the chrome plating layer 13 can still provide rust protection for the elastic metal wire 6 even after the first protective cover 8 and the second protective cover 9 are damaged.

[0028] like Figure 3As shown, a second protective cover 9 is further provided on the outer surface of the spring core wire 7. The second protective cover 9 is made of a sealing rubber material, or other sealing materials with deformation properties. A sealant 12 is filled between the second protective cover 9 and the first protective cover 8. In actual use, the second protective cover 9 and the sealant 12 can provide secondary protection for the elastic metal wire 6, further preventing the elastic metal wire 6 from being oxidized and corroded by oxygen in the external air.

[0029] Specifically, when the present invention is in use, the staff first fixes the second strip connecting plate 5 on the support pad 1 with the first strip connecting plate 3 fixed on the first support section 10, and then installs the four-core spring in the mattress. The first protective cover 8 can isolate the oxygen in the air on the side of the elastic metal wire 6, so that the elastic metal wire 6 will not be oxidized and rusted by oxygen. The second protective cover 9 and the sealant 12 are then used for secondary protection to protect the elastic metal wire 6. Under the action of the support pad 1, the contact parts of the two ends of the four-core spring and the mattress can be kept stable without damaging the mattress. After the user lies on the mattress, the user will not be hurt by the end of the first support section 10.

[0030] Furthermore, Figure 3 As shown, the four elastic metal wires 6 are arranged to be spirally wound around each other, which can increase the strength of the spring core wire 7. When the spring is subjected to excessive pressure, the spring core wire 7 will not lose its elasticity due to excessive deformation.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
