The buttocks are an important supporting part of the human body, bearing the weight of the upper body. The seat cushion can effectively disperse the pressure on the muscles and bones of the buttocks.

[0003] For example, an elastomeric seat cushion with publication number CN217852117U relates to the technical field of seat cushions and comprises an outer sleeve and a core body, wherein the outer sleeve is arranged on the outside of the core body, and the core body comprises a sponge body and an elastomer, wherein the sponge body has a accommodating cavity, wherein an elastomer is arranged in the accommodating cavity, and wherein a plurality of independent elastic cavities are arranged in the elastomer body, wherein an elastic member is placed in the elastic cavity, and the two ends of the elastic member are respectively in conflict with the upper and lower walls of the elastic cavity. The utility model designs an independent spring, and the outside of the spring is molded with two layers of non-woven fabric, and utilizes the spring and the sponge pad to enhance the elastic force of the seat cushion.

[0004] In the prior art, the support structure of the seat cushion is usually composed of a combination of independent springs. This design enables each spring to work independently to provide the support force required by the seat cushion. A potential problem with this structure is that once one of the springs is damaged, it may extend from the inside of the seat cushion to the outside, thereby increasing the risk of potential harm to the human body. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-slip fixed composite cushion, comprising an installation box, a support frame, and a cushion surface, wherein the support frame is fixedly connected to the top of the installation box, and the support frame is set to an elastic material, and the cushion surface is fixedly connected to the inside of the support frame;

[0007] The pad surface is set to be a woven elastic material, and a plurality of limit holes distributed in a matrix are set inside the pad surface, an adaptive structure is set inside the installation box, the adaptive structure is provided with a central support block, and the central support block is set to be rectangular, and the four corners of the bottom of the central support block are fixedly connected to support springs, the adaptive structure is also provided with corner support blocks, and the corner support blocks are set to be right-angled sectors, and the bottom corners of the corner support blocks are fixedly connected to support springs;

[0008] A limiting structure for limiting the shape of the pad surface is arranged between the pad surface and the installation box, and fixing structures for fixing the device are arranged on both sides of the installation box.

[0009] Furthermore, the center support block and the corner support blocks are both provided with slots at right angles, and the bottom of the support spring is fixedly connected to the bottom of the installation box.

[0010] Furthermore, twelve central support blocks are provided, and four corner support blocks are provided, and the twelve central support blocks and the four corner support blocks form a quasi-rectangular structure, and the quasi-rectangular structure fits with the bottom of the pad surface.

[0011] Furthermore, the limiting structures are provided in plurality and distributed in a matrix at the bottom of the installation box, and the limiting structures are aligned with the plurality of pads.

[0012] Furthermore, the limiting structure is provided with a fixed cylinder, and a sliding rod is slidably connected inside the fixed cylinder, a limiting button is fixedly connected to the top of the sliding rod, and a connecting plate is fixedly connected to the middle outer side of the sliding rod, a pull-down spring is fixedly connected to the bottom of the limit button, and the pull-down spring is located inside the fixed cylinder, and the pull-down spring and the bottom of the fixed cylinder are both fixedly connected to the bottom of the installation box.

[0013] Furthermore, the slide bar is located inside the limiting hole, and the limiting button is located on the top of the pad surface, and the limiting button is aligned with the limiting hole, the outer side of the connecting piece is snap-connected to the inside of the card slot, and the connecting piece is set to an elastic material.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The anti-slip fixed composite seat cushion is provided with an adaptive structure. When the human body's buttocks exert downward pressure on the cushion surface, the cushion surface will drive the central support block and the corner support blocks to compress the support spring. During this process, the angles of the central support block and the corner support blocks will be adjusted accordingly to adapt to the curve of the human buttocks, thereby achieving adaptation and support for the curve of the human buttocks.

[0017] Furthermore, a limiting structure is provided. When the corner support blocks and the center support block are displaced, the center support block and the corner support block move the driving connecting piece of the slot downward, thereby guiding the slide bar to move downward synchronously with the connecting piece. Since the connecting piece is designed as an elastic structure, it will make the movement of the surrounding corner support blocks and the center support block consistent with the movement of the connecting piece through the action of the slot, thereby forming a coordinated whole. The elastic material characteristics of the connecting piece make the center support block and the corner support block not completely synchronized when following the movement of the connecting piece. This non-completely synchronized movement mode can effectively prevent the support spring from excessively protruding when driving a single center support block or a corner support block, thereby avoiding discomfort to the buttocks of the human body.

[0018] Furthermore, a fixing structure is provided, and by operating the pull groove, the rotating plate is caused to rotate around the connecting block, and the seat cushion is installed to the top of the chair surface. Subsequently, the pull groove is released, and the rotating plate continues to rotate around the connecting block toward the inside of the installation box until a plurality of fixing teeth are fitted with the bottom of the chair, thereby achieving a firm fixation of the seat cushion.

[0028] When the human body's buttocks exerts downward pressure on the cushion surface 3, the cushion surface 3 will drive the central support block 6 and the corner support blocks 7 to compress the support spring 5. During this process, the angles of the central support block 6 and the corner support blocks 7 will be adjusted accordingly to adapt to the curve of the human body's buttocks, thereby achieving adaptation and support for the curve of the human body's buttocks.
