Description

Technical Field

[0001] The utility model relates to the technical field of mattress springs, in particular to a 5R-shaped mattress spring. Background Art

[0002] A spring is an elastic element with a very wide range of uses. Its outer 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. This 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] Among them, the utility model with the application number CN202322161677.0 discloses an elastic bed net structure. The bed net structure includes a frame structure. The frame structure includes two upper and lower corresponding upper frames and lower frames. Both the upper frame and the lower frame are rectangular frame structures; it also includes a spring structure. The spring structure includes a mattress spring and a bubble spring. The mattress spring is located between the upper frame and the lower frame. The bubble spring protrudes from the surface of the upper frame, and the mattress spring and the bubble spring are an integrated spring structure; by using a combined integrated spring structure of the mattress spring and the bubble spring, and the bubble spring protruding from the surface of the upper frame, the elasticity and softness of the mattress surface are increased through the bubble spring, and there is no need to add a latex pad on the mattress surface, and the integrated spring structure can simplify the manufacturing process of the mattress.

[0005] Most of the existing spring structures adopt a single spring body design. The pressure resistance of this structure is average. When the force is large, it is easy to break. Content of the Utility Model

[0006] The purpose of the utility model is to provide a 5R-shaped mattress spring aiming at the deficiencies of the prior art.

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

[0008] A 5R-shaped mattress spring includes a spring body. A top support ring is formed at the top of the spring body, and a bottom support ring is formed at the bottom of the spring body. The spring body includes a first spring main body and a second spring main body. The cross-sectional shapes of both the first spring main body and the second spring main body are elliptical. Among them, a notch is formed along the length direction of the first spring main body, and the second spring main body is embedded into and integrally formed with this notch.

[0009] Further: The elliptical diameter of the first spring main body is 2.5 mm.

[0010] Further: The minor axis of the ellipse of the first spring main body is 1.8 mm.

[0011] Further: The depth of the notch is 0.9 mm, and the width of the notch is 1.8 mm.

[0012] Further: The notch has a radian, and the diameter of the notch is 2.3 mm.

[0013] Further: The surface of the spring body is coated with a corrosion-resistant layer.

[0014] The beneficial effects of the present utility model: Adopting the structure of a double spring main body, the first spring main body and the second spring main body are integrally formed and connected through a notch to form a spring body; the structure of the double spring main body can effectively increase the supporting force. At the same time, support ring structures are formed at both ends of the spring body. When placed vertically, it not only avoids the bad points that are prone to breakage under pressure but also enhances the compressive and anti-fatigue durability of the spring body; squeezing or cutting off 1 / 4 of the other side where the spring body is erected can reduce the self-weight of the spring and increase the resilience of the spring itself. Without affecting the comfort of the mattress, it can also meet the operability requirements of different people during handling and maintenance. Description of the Drawings

[0020] The present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figure 1-2As shown in the figure, a 5R-shaped mattress spring includes a spring body 1. A top support ring 11 is formed at the top of the spring body 1, and a bottom support ring 12 is formed at the bottom of the spring body 1. The spring body 1 includes a first spring main body 13 and a second spring main body 14. The cross-sectional shapes of both the first spring main body 13 and the second spring main body 14 are elliptical. Among them, a notch 15 is formed along the length direction of the first spring main body 13, and the second spring main body 14 is embedded into and integrally formed with the notch 15.

[0022] Adopting the structure of a double spring main body, the first spring main body 13 and the second spring main body 14 are integrally formed and connected through the notch 15 to form the spring body 1. The structure of the double spring main body can effectively increase the supporting force. At the same time, support ring structures are formed at both ends of the spring body 1. When placed vertically, it not only avoids the bad points that are prone to breakage under pressure but also enhances the compressive and anti-fatigue durability of the spring body 1. Squeezing or cutting off 1 / 4 of the other side where the spring body 1 is erected can reduce the self-weight of the spring and increase the resilience of the spring itself. On the premise of not affecting the comfort of the mattress, it can also meet the operability requirements of different people during handling and maintenance.

[0023] The major axis diameter of the first spring main body 13 is 2.5 mm. The minor axis diameter of the first spring main body 13 is 1.8 mm. The steel wire coil is extruded by an extrusion device to form the first spring main body 13 with an elliptical cross-section of 1.8 / 2.5.

[0024] The depth of the notch 15 is 0.9 mm, the width of the notch 15 is 1.8 mm, the notch 15 has a radian, and the diameter of the notch 15 is 2.3 mm. After the first spring main body 13 with an elliptical shape is extruded, it is then extruded by a moon-shaped mold or cut and separated by a tool to form the notch 15 on the first spring main body 13 for the second spring main body 14 to be embedded and connected.

[0025] Furthermore: 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. This can improve the rust-proof performance of the spring body 1.

[0026] The ellipse is composed of four different arc segments. The first spring main body 13 in this solution is formed with a notch 15 with a diameter of 2.3 mm on the basis of the original ellipse. Therefore, the cross-sectional shape of the first spring main body 13 in this solution is composed of five different arc segments, thus forming a 5R-shaped spring.

[0027] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency that has never existed in the prior art during use and thus having practicality, becoming a product with extremely high practical value.

[0028] 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 on the present utility model.
