[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model is described clearly and completely, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] The composite independent spring provided in the embodiments of the application solves the problems that the independent spring is pressed and extruded by the flexible sponge latex material on the upper layer of the mattress in actual use, the sharp part is easy to damage the sponge and latex, and the spring in the extruded area often has a rapid decline in elasticity effect in actual use, resulting in the collapse of part of the area of the mattress.

[0021] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and specific embodiments.

[0022] The utility model discloses a composite independent spring.

[0023] According to the drawings, Figs. 1-3 As shown, it comprises an outer spring cover 1, the inside of the outer spring cover 1 is provided with a built-in elastic support 2, the built-in elastic support 2 comprises a straight line spring 21, a spring net 22 and a shaping ring 23;

[0024] The shaping ring 23 is arranged at the two ends of the straight line spring 21, the spring net 22 is fixedly installed inside the shaping ring 23, the two ends of the straight line spring 21 are fixedly connected with the spring net 22, the two ends of the outer spring cover 1 are movably clamped with the spring net 22, the outer surface of the spring net 22 is provided with a rubber sheath 24, and the shaping ring 23 is fixedly arranged on the inner wall of the rubber sheath 24. By arranging the built-in elastic support 2 in the inside of the traditional outer spring cover 1, the built-in elastic support 2 is wrapped around the two ends of the outer spring cover 1 through the two ends of the shaping ring 23, the spring net 22 and the rubber sheath 24, so that when the outer spring cover 1 contacts the flexible material of the mattress, the puncture damage to the flexible material can be avoided, the rubber sheath 24 can further protect the flexible material of the mattress, and the rubber sheath 24 can be fixed with the flexible material of the mattress in the form of sewing or binding, so that the composite independent spring will not be deviated and tilted in the mattress.

[0025] The inner wall of the spring net 22 is fixedly provided with a positioning snap ring 25, and the two ends of the outer spring sleeve 1 are movably clamped in the positioning snap ring 25. The two ends of the outer spring sleeve 1 are fixed by the positioning snap ring 25, so that the two ends of the outer spring sleeve 1 directly act on the spring net 22. The spring net, as a flexible material, can uniformly disperse the extrusion contact force, thereby avoiding the case that the flexible material is pierced due to the direct contact of the sharp end with the flexible material of the mattress.

[0026] The two ends of the outer spring sleeve 1 are flared, and the outer diameter of the outer spring sleeve 1 gradually increases from the middle to the two ends, so that the two ends of the outer spring sleeve 1 have larger contact areas, which can support more stably and are not easy to be laterally tilted and deformed in use.

[0027] The pitch of the two ends of the outer spring sleeve 1 is large, and the pitch of the middle part of the outer spring sleeve 1 is small. The large pitch of the two ends makes the entire outer spring sleeve 1 compressed first at the two ends and then at the middle part, so that the whole collapses symmetrically and folds, avoiding the noise caused by the mutual extrusion and friction of the springs in linear compression.

[0028] The wire diameter of the two ends of the outer spring sleeve 1 is thick, and the wire diameter of the middle part of the outer spring sleeve 1 is thin, so that the two ends of the outer spring sleeve 1 are less prone to plastic deformation, and the strength of the two ends is also higher.

[0029] The wire diameter of the linear spring 21 is larger than that of the outer spring sleeve 1, and the elastic coefficient of the linear spring 21 is larger than that of the outer spring sleeve 1. The built-in elastic support 2 provides additional elastic force for the outer spring sleeve 1 through the linear spring 21, so that the elastic force of the outer spring sleeve 1 can support the mattress surface after being extruded for a long time, avoiding the collapse of the mattress surface. The linear spring 21 has better elastic force and strength.

[0030] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
