Description

Technical Field

[0001] The utility model relates to the technical field of mattress springs, in particular to an orchid-shaped mattress spring. Background Art

[0002] The springs used on spring mattresses are all independent. After being arranged on the mattress, they are strung into a net with steel wires. Since these springs are independent of each other, the integrity is not good.

[0003] Therefore, there is a kind of Bonnell spring on the market. This spring is wound by a whole steel wire along the sleeping direction of the human body. Therefore, the integrity is better than that of individual independent springs. However, the current Bonnell spring also has defects. The top and bottom of each spring are triangular, and part of the projection of the middle position of the spring is located outside the bottom and top of the spring. Therefore, when the spring is stressed, the stress at the middle position and the bottom of the spring is not on the same straight line, which may generate torsion, so the stability is not strong and it is necessary to be improved.

[0004] The utility model with the application number CN202322321115.8 discloses a spring for a spring mattress, which includes a plurality of monomers. The monomers are wound by steel wires. The monomers are divided into end parts and a middle part. The middle part is in a spiral shape. The middle part connects the two end parts. One end parts of adjacent two monomers are connected together. Along the axial direction projection of the middle part, the projection of the middle part is located within the projection of the end part. Since the projection of the middle part is located within the projection of the end part, when the end part is stressed, the stress direction will be consistent with the force transmission direction of the middle part. Therefore, there will be no torsional problem and the spring is more stable.

[0005] Most of the existing mattress spring structures are spiral structures, and the spring bodies are arranged along the spiral direction; this traditional structure has relatively general support stability and poor elastic support force. When used in a mattress to support a person with a large body weight, the depression is relatively serious, affecting the use. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an orchid-shaped mattress spring in view of the deficiencies of the prior art.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] An orchid-shaped mattress spring includes spring monomers, which are wound by steel wires. The spring monomers are divided into a top annular support part, a bottom annular support part and a middle spiral part; wherein the middle spiral part of the spring monomer is in a wavy structure.

[0009] Further: The cross-section of the spring monomer is circular.

[0010] Furthermore, the top annular support part and the bottom annular support part are parallel to each other.

[0011] Furthermore, the number of spring units is multiple, and two adjacent spring units are connected.

[0012] Furthermore, the top annular support part and the bottom annular support part are respectively provided with two layers.

[0013] Furthermore, the middle helical part has more than three layers.

[0014] Furthermore, the diameter of the middle helical part is larger than the diameters of the top annular support part and the bottom annular support part.

[0015] Furthermore, the top annular support part, the bottom annular support part and the middle helical part are coaxially aligned respectively.

[0016] The beneficial effects of the present utility model are as follows: Due to the design of the top annular support part and the bottom annular support part, the spring units can be placed vertically. During elastic support, the top can achieve planar support, and the bottom can be in surface contact with the support area, improving the stability of the support and reducing the occurrence of left - right shaking. In addition, since the middle helical part has a wavy structure, compared with the traditional smooth arc structure, the required wire length increases. The overall height and diameter of the spring units remain unchanged, which can increase the elastic support force. When being pressed under force, the shaking amplitude decreases and the stability is further improved. Description of the Drawings

[0017] Figure 1 It is a schematic structural diagram of the spring unit.

[0018] The reference signs include:

[0019] 1 - Spring unit,

[0020] 11 - Top annular support part, 12 - Bottom annular support part, 13 - Middle helical part. Detailed Embodiment

[0021] The present utility model will be described in detail below with reference to the drawings.

[0022] As Figure 1As shown, an orchid-shaped mattress spring includes a spring unit 1, which is formed by winding steel wire. The spring unit 1 is divided into a top annular support portion 11, a bottom annular support portion 12 and an intermediate spiral portion 13; wherein the intermediate spiral portion 13 of the spring unit 1 is in a wavy structure. The design of the top annular support portion 11 and the bottom annular support portion 12 enables the spring unit 1 to be placed vertically. During elastic support, the top can achieve planar support, and the bottom can be in surface contact with the support area, thereby improving the stability of the support and reducing the occurrence of left and right shaking. In addition, since the intermediate spiral portion 13 is in a wavy structure, the required steel wire length is increased compared to the traditional smooth arc structure. The overall height and diameter of the spring unit 1 remain unchanged, which can increase the elastic support force. When pressed downward by force, the amplitude of shaking is reduced, and the stability is further improved.

[0023] Furthermore, the cross section of the spring unit 1 is circular.

[0024] The top annular support portion 11 and the bottom annular support portion 12 are respectively provided with two layers, and the middle spiral portion 13 has more than three layers; the multi-layer design can increase the elastic supporting force, and when used in a mattress, it can support objects of greater weight and rebound smoothly.

[0025] The top annular support portion 11 and the bottom annular support portion 12 are parallel to each other. Since the top annular support portion 11, the bottom annular support portion 12 and the middle spiral portion 13 are coaxially aligned, when the top annular support portion 11 is subjected to force, the force direction will be consistent with the force transmission direction of the middle spiral portion 13, so there will be no torsion problem, and the spring will be more stable.

[0026] There are multiple spring monomers 1, and two adjacent spring monomers 1 are connected. Multiple spring monomers 1 form a modular spring, and multiple modular springs are placed in the mattress to form a force-bearing surface more evenly.

[0027] Preferably, the diameter of the middle spiral portion 13 is larger than the diameters of the top annular support portion 11 and the bottom annular support portion 12. When subjected to force, the multi-layer structure of the middle spiral portion 13 can increase the elastic support force, and the whole is not easy to deform and has better stability.

[0028] Since the middle spiral portion 13 is in a wave-shaped structure, it cooperates with the top annular support portion 11 and the bottom annular support portion 12 to form an orchid-shaped mattress spring.

[0029] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0030] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
