Technical Field

[0001] This utility model relates to the technical field of anti-collapse devices, and in particular to anti-collapse sofa filling sponge. Background Technology

[0002] Sofas are now a necessity for many families. Sofas sold on the market are generally divided into three types: low-back sofas, high-back sofas, and ordinary sofas that fall between the two. "Sofa" is a foreign word, a transliteration of the English word "sofa". It is a type of upholstered chair with multiple seats, a backrest with springs or thick foam, and armrests on both sides.

[0003] Existing sofa anti-collapse devices have complex structures, are inconvenient to disassemble and install, are difficult to transport and carry, have poor anti-collapse effects, poor sofa elasticity, and are uncomfortable to use.

[0004] Therefore, an anti-collapse sofa filling sponge is proposed, which has the advantage of good anti-collapse effect, thereby solving the problems in the background technology mentioned above. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-collapse sofa filling sponge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-collapse sofa filling sponge body, comprising a cover and a sponge filling body installed inside it. The inner side of the cover is provided with an inner lining layer, which is located in the gap between the cover and the sponge filling body. The sponge filling body is composed of several sponge blocks bonded together, and a splicing line is formed between two adjacent sponge blocks. A receiving cavity is opened between two adjacent sponge blocks. An anti-collapse component is embedded in the receiving cavity of the sponge filling body, and two support plates are provided in the middle of the anti-collapse component. A telescopic rod is installed between the two support plates of the anti-collapse component, and a spring is sleeved on the surface of the telescopic rod to abut against the two support plates. Support pads are attached to the top and bottom surfaces of the sponge filling body, and the support pads are bonded to the end faces of the anti-collapse component.

[0007] As a further description of the above technical solution: the surface of the cover is provided with a loading and unloading opening, and the periphery of the loading and unloading opening is provided with an edge band that is sewn together with the cover.

[0008] As a further description of the above technical solution: the inner lining layer is made of silicone, and the middle part of the inner lining layer is provided with a pleated section with a wavy cross-section.

[0009] As a further description of the above technical solution: both ends of the anti-collapse component are provided with frustum portions, and the frustum portions are bonded to the support pad.

[0010] As a further description of the above technical solution: both ends of the support pad are provided with crescent-shaped portions, and the crescent-shaped portions are in contact with the edge of the sponge filler.

[0011] As a further description of the above technical solution: the thickness of the sponge filler is matched with the height of the anti-collapse component, and the contour of the internal space of the accommodating cavity is adapted to the shape of the anti-collapse component.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, a spliced ​​sponge filling body is constructed from equally divided sponge blocks, with splicing lines between adjacent sponge blocks. A receiving cavity for placing the anti-collapse component is provided at the splicing lines. Two support pads are attached to the upper and lower surfaces of the sponge filling body, respectively, and are also bonded to the two ends of the anti-collapse component. When the sponge body is compressed, the silicone inner lining layer inside the sleeve maintains elasticity and comfort in contact with the user. The compressed sponge body compresses the anti-collapse component through the support pads, causing the spring and telescopic rod in the middle of the anti-collapse component to adaptively contract, achieving pressure buffering and kinetic energy absorption. With this structure, the contact area between the sponge filling body and the user can be increased through the support pads, avoiding local collapse caused by long-term pressure on the sponge filling body.
