Description

Technical Field

[0001] The utility model belongs to the technical field of household articles, and in particular relates to a spring bed core structure and a spring mattress thereof. Background Art

[0002] As people's living standards continue to improve, people's requirements for sleep quality are getting higher and higher. Mattresses are used between the human body and the bed to ensure that people get healthy and comfortable sleep. Spring mattresses are commonly used in modern times and have good performance. The bed core is composed of springs. Spring mattresses have the advantages of good elasticity, good support and high comfort.

[0003] However, traditional spring mattresses are not completely ergonomically designed. Some spring cores have excessive deformation, which can easily lead to collapse, while others have too small deformation, which causes the deformation in different positions to be almost the same. They cannot fit the human body curve well, are generally comfortable, and cannot enable people to achieve the best sleeping state when sleeping.

[0004] Therefore, a spring bed core structure and a spring mattress thereof are designed to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model. Utility Model Content

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a spring bed core structure and a spring mattress thereof.

[0007] In order to achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a spring bed core structure, including a plurality of spring bodies arranged in a row and a tension spring body used to connect the spring bodies in two adjacent rows;

[0008] Both ends of the spring body are open structures, and both ends of the spring body are provided with a free end; both ends of the spring body include two straight portions arranged opposite to each other, and the two straight portions are connected by a connecting portion;

[0009] Both ends of the tension spring body are open structures, and both ends of the tension spring body are provided with a hook end.

[0010] In this solution, both ends of the spring body are open structures. When the axial direction of the spring body is under pressure, the opening at the end will become larger, and when no pressure is applied, the opening will return to its initial size. The size of the pressure is proportional to the size of the opening of the spring body. The spring bodies are arranged in a row and connected by tension spring bodies, so that different stress positions of the spring bed core will produce different degrees of deformation, which can better fit the curve of the human body.

[0011] Furthermore, the two ends of each of the spring bodies are respectively connected to a tension spring body, the tension spring body is arranged along the length direction of the straight portion, and the tension spring body connects and winds the two straight portions of the same end of two adjacent spring bodies close to each other inside. In this solution, the straight portion of the spring body is arranged inside the tension spring body by winding, which can ensure that the tension spring body is firmly connected to the spring body and is not easy to fall off.

[0012] Furthermore, the connecting portion is an arc segment. In this solution, the connecting portion is set as an arc segment, so that the spring body can have better elasticity and flexibility when subjected to force, and the spring bed core can automatically fit the human body when subjected to pressure, making the human body feel more comfortable.

[0013] Furthermore, the axial centerline of the hook end is perpendicular to the axial centerline of the tension spring body. In this solution, the hook end is bent relative to the tension spring body, which plays a limiting role, ensuring that the tension spring body and the straight part of the spring body are firmly wound, preventing the two ends of the tension spring body from rotating or loosening.

[0014] Furthermore, the straight portion is arranged in the axial center area of ​​the tension spring body. In this solution, the straight portion is arranged in the axial center area of ​​the tension spring body, which can be more uniform and stable when subjected to force.

[0015] Furthermore, the rotation directions of the spring bodies in two adjacent rows are opposite. In this solution, one of the spring bodies in two adjacent rows is left-handed and the other is right-handed, which can make the force effect of the spring body better.

[0016] Furthermore, two adjacent straight sections in the same tension spring body, one of which has N rings strung in it, and the other of which has N+1 rings strung in it, wherein N is an integer greater than or equal to 4. In this solution, at least 4 rings of the tension spring are strung in the straight section, so that the spiral of the tension spring body can be denser, and the elasticity of the tension spring can be better.

[0017] Furthermore, it also includes an upper frame and a lower frame arranged in parallel, and the upper frame and the lower frame are respectively connected to the two ends of the spring body. In this solution, the arrangement of the frame makes the structure of the spring bed core more stable and the edge of the spring bed core is more evenly stressed.

[0018] Furthermore, the upper frame and the lower frame are both provided with a plurality of clamps, and the spring bodies at the edges are respectively inserted into the corresponding clamps. In this solution, the spring body is connected to the upper frame and the lower frame by inserting the spring body into the clamps, which is convenient for assembly and disassembly and has a firm connection.

[0019] The utility model also provides a spring mattress, the interior of which comprises the spring core structure described in any one of the above technical solutions.

[0020] Due to the application of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0021] The spring bed core structure and spring mattress designed by the utility model set both ends of the spring body into open structures. When the axial direction of the spring body is compressed, the openings at the ends will become larger, and the pressure is proportional to the size of the opening of the spring body. Different stress positions of the spring bed core will produce different degrees of deformation, which can better fit the curve of the human body and make the human body feel more comfortable.
