Description

Technical Field

[0001] The utility model relates to the technical field of sponge mattresses, in particular to a compression-resistant and deformable sponge mattress. Background Art

[0002] Sponge, usually made by foaming polyurethane materials, has a certain elasticity and softness.

[0003] The sponges of sponge mattresses are usually divided into three categories: ordinary sponges, memory sponges, and high-resilience sponges. Ordinary sponges provide basic softness and elasticity, and the softness and hardness of the mattress can be adjusted by different densities and thicknesses.

[0038] Working principle: When using the compression-deformation-resistant sponge mattress, the pressure applied to the low-noise sponge 3 is transmitted to the latex 4, and then to the pressure plate 7, causing the pressure plate 7 to drive the slider 6 to press down on the support spring 8. When the support spring 8 is compressed to a certain extent, the movement of the slider 6 will cause the fixing column 9 on the fixed pressure plate 7 to pull the return spring 16. The pulling of the return spring 16 will relieve the movement of the fixed block 11 to a certain extent, and then prevent the low-noise sponge 3 around the pressure plate 7 area from having excessive depressions. On the contrary, the pulling of the return spring 16 will also enhance the resilience of the pressure plate 7, thereby reducing the generation of certain indentations and enhancing its service life, which is beneficial to improving the compression-deformation resistance of the sponge mattress.

[0039] When using a sponge mattress with a folding function, first pull the handle 204 upward, and then the sliding rod 203 drives the first sliding column 205 to move upward. When the first sliding column 205 squeezes the spring column 206 to a certain limit, the spring column 206 drives the second sliding column 207 and the rotating rod 208 to move. Under the action of the rotating column 209 and the fixing plate 210, the other end of the rotating rod 208 drives the moving rod 211 and the gear catch 212 to move downward, so that the gear catch 212 disengages from the circular gear 213. Finally, under the action of the shaft rod 214, this sponge mattress can then be folded, thereby saving the occupied area of this sponge mattress and facilitating its handling and movement.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
