Description

Technical Field

[0001] The utility model relates to the technical field of sponge pads, in particular to a sponge pad. Background Art

[0002] Sponge pads are loved by people nowadays because of their suitable hardness and softness. At present, sponge pads are widely used on mattresses or sofa cushions. Many existing sponge pads are made into columns when used on mattresses and are evenly distributed on the bottom plate. However, when installing them, they need to be equipped with a whole elastic grid of the same size as the mattress. They are assembled through the elastic grid. Therefore, not only is the assembly troublesome, but also the whole mattress needs to be lifted after the assembly is completed. If you are not careful, the combined unit will be separated from the elastic grid. Therefore, the utility model provides a multifunctional sponge pad with moderate softness, convenient production, convenient disassembly and assembly, and firm connection.

[0003] In order to solve the above technical problems, a Chinese patent with the announcement number CN210114248U in the prior art discloses a sponge pad, which includes foam columns, a high-density composite board and a bottom plate: the foam columns are evenly arranged and inserted into the perforations of the high-density composite board, and the high-density composite board is connected to the bottom plate. The foam columns are moderately soft and will not make the table and bed too soft or too hard, and the high-density composite board plays a supporting role.

[0004] Although the above-mentioned prior art solution can be disassembled and assembled, and has various functions, when the bottom plate is upward, it is a table, and when the columnar body formed by the sponge pad is upward, it can be installed as a mattress or a children's activity place. However, when assembling the bottom plate with the high-density composite board and the foam column, it is necessary for personnel to twist each group of bolts one by one to disassemble and assemble the groove, which is relatively cumbersome, increases the workload of the staff, and affects the efficiency of disassembly and assembly and maintenance.
