Description

Technical Field

[0001] The utility model relates to the technical field of mattress springs, in particular to a 6R-shaped mattress spring. Background Art

[0002] A spring is an elastic element with a very wide range of uses. Its shape is usually cylindrical, and the production and processing can be divided into cold coiling forming and hot coiling forming. Different industries use springs with different strengths, stiffnesses, and service lives according to different uses.

[0003] The bed net is the internal structure of the mattress. The bed net is composed of a frame and springs. Springs are the main components to improve the comfort of the mattress; traditional mattresses generally increase the overall elasticity and softness of the mattress surface by adding a layer of silica gel or latex layer on the mattress surface, or adding another layer of springs on the mattress surface and then wrapping the springs to form a spring cushion layer, which will make the manufacturing process of the mattress very complicated. However, without such a structure, the softness and elasticity of the mattress will be greatly reduced.

[0004] The utility model with the application number CN202323013571.2 is applicable to the technical field of mattress springs and provides a spring for a mattress, including a spring body composed of a plurality of coil turns. The spring body is a soft spring; a first end part arranged at the upper end of the spring body and having a vortex disk-like structure, the first end part is led out from the upper end of the spring body and is composed of a plurality of coil turns with gradually decreasing outer diameters; a second end part arranged at the lower end of the spring body and having a circular ring-like structure, the second end part is led out from the lower end of the spring body and is composed of a single coil turn. By arranging a buffer spring inside the spring body, when the spring body 1 is subjected to a large force, the deformation amount of the spring body is reduced to protect the spring body from deformation damage and improve the service life of the spring body. At the same time, when the force is moderate, the top end of the buffer spring will not contact the first end part on the spring body, and the spring body deforms freely to provide good comfort for users.

[0005] Most of the existing spring structures adopt a single spring body design. The pressure resistance of this structure is average, and when subjected to a large force, it is prone to breakage. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a 6R-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] A 6R-shaped mattress spring includes a spring body, characterized in that: a top support ring is formed at the top of the spring body, a bottom support ring is formed at the bottom of the spring body, and the spring body includes a first spring body and a second spring body;

[0009] The first spring body is cut with a first connection surface along the length direction, and the second spring body is cut with a second connection surface along the length direction. The first connection surface of the first spring body and the second connection surface of the second spring body are connected to form the spring body of an integral structure; the cross-section formed after the connection of the first spring body and the second spring body is an "8" shape arranged symmetrically.

[0010] Furthermore: The raw materials of the first spring body and the second spring body are wire rods with a diameter of 6.0 - 6.5 mm.

[0011] Furthermore: The cross-sections of the first spring body and the second spring body are both ellipses with a size of 1.8 / 2.5.

[0012] Furthermore: The overall width of the spring body is 2.8 mm.

[0013] Furthermore: The widths of the first connection surface and the second connection surface are 1 mm.

[0014] Furthermore: The surface of the spring body is coated with a corrosion-resistant layer.

[0015] The beneficial effects of the present utility model: The spring body of this solution adopts the characteristics of double-circle symmetry, increasing the stress points of the spring body, making the compressive and fatigue resistance of the spring body double, and extending the service life. While having the same bearing strength as a circular steel wire with the same diameter, this kind of spring body also reduces the self-weight of the spring, enhances the resilience of the spring itself, and doubles the comfort and experience.

[0021] The following describes the present utility model in detail with reference to the drawings.

[0022] As Figure 1-2 shown, a 6R-shaped mattress spring includes a spring body 1, and the spring body 1 includes a first spring body 11 and a second spring body 12.

[0023] The first spring body 11 is cut with a first connection surface 13 along the length direction, and the second spring body 12 is cut with a second connection surface 14 along the length direction. The first connection surface 13 of the first spring body 11 and the second connection surface 14 of the second spring body 12 are connected to form the spring body 1 of an integral structure; the cross-section formed after the connection of the first spring body 11 and the second spring body 12 is an "8"-shaped symmetrically arranged.

[0024] The spring body 1 of this solution adopts the characteristics of double-circle symmetry, increasing the stress points of the spring body 1, making the compressive resistance and fatigue resistance of the spring body 1 double, and extending the service life. While having the same bearing strength as a circular wire of the same diameter, this kind of spring body 1 also reduces the self-weight of the spring, enhances the resilience of the spring itself, and doubles the comfort and experience.

[0025] The raw materials of the first spring body 11 and the second spring body 12 are wire rods with a diameter of 6.0 - 6.5 mm; the wire rods of 6.0 - 6.5 mm are successively processed through a hole cutter of 5.0 mm, a hole cutter of 4.0 mm, a hole cutter of 3.0 mm, and a hole cutter of 2.5 mm to form a preliminary spring body 1.

[0026] The cross-sections of the first spring body 11 and the second spring body 12 are both ellipses of 1.8 / 2.5. The preliminary spring body 1 is drawn into the spring body 1 by extrusion. Then it is drawn into an "8"-shaped symmetrically arranged up and down through a gourd-shaped mold.

[0027] Furthermore, the overall width of the spring body 1 is 2.8 mm.

[0028] Furthermore, the width of the first connection surface 13 and the second connection surface 14 is 1 mm.

[0029] Furthermore, a top support ring 15 is formed at the top of the spring body 1, and a bottom support ring 16 is formed at the bottom of the spring body 1. The use of the top support ring 15 and the bottom support ring 16 can increase the support area, further improve the support stability, and prevent the phenomenon of the mattress from sagging.

[0030] The surface of the spring body 1 is coated with a corrosion-resistant layer, and the corrosion-resistant layer is an epoxy resin or polyolefin coating. It can improve the rust-proof performance of the spring body 1.

[0031] The ellipse is composed of four different arc segments. The first spring body 15 in this solution is formed with a first connection surface 13 or a second connection surface 14 with a width of 1 mm on the basis of the original ellipse; therefore, the cross-sectional shape formed by the first spring body 11 and the second spring body 12 in this solution is composed of 6 different arc segments, thus forming a 6R-shaped spring.

[0032] As described above, it can be seen that the present utility model has the excellent characteristics described above, enabling it to enhance the efficiency unprecedented in the prior art during use and thus having practicality, becoming a product with extremely high practical value.

[0033] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
