[0031] Figures 1 to 4The inflatable hollow cushion shown comprises a cushion body 1 , an air pipe 4 is provided on one side of the cushion body 1 , and a fixing device 2 is provided on one side of the cushion body 1 .

[0032] Figures 1 to 4 The fixing device 2 shown includes a square tube 21, which is fixedly connected to the cushion body 1, and a fixing belt 22 is slidably connected inside the square tube 21. A plurality of threaded tubes 23 are fixedly connected to one side of the fixing belt 22. A threaded bolt 24 is provided on the side of the fixing belt 22 away from the threaded tube 23, and the bolt 24 is threadedly connected to the threaded tube 23. When the inflatable hollow cushion is used, the air pipe 4 of the cushion body 1 is inflated by an air pump to expand the cushion body 1 to form a hollow cushion for use. When using the cushion body 1, the fixing belt 22 inside the square tube 21 can be moved to make the fixing belt 22 contact with the chair, and then the bolt 24 on one side of the fixing belt 22 can be passed through the fixing belt 22 to reach the inside of the threaded tube 23 on the other side of the fixing belt 22, and then the fixing belt 22 and the chair can be fixed, thereby completing the fixation of the cushion body 1 and the chair to avoid the position movement of the cushion body 1. By using the fixing device 2, the cushion body 1 can be fixed to avoid the position shift of the cushion body 1 on the chair, which then affects the user's sitting posture, thereby improving the use effect of the cushion body 1.

[0033] Figures 1 to 4 One side of the bolt 24 shown is fixedly connected with a plurality of anti-sliding blocks 3625, and the plurality of anti-sliding blocks 3625 are arranged in a circumferential order on one side of the bolt 24. By using the anti-sliding blocks 3625, the friction between the bolt 24 and the user is increased, so that the bolt 24 can be rotated more easily. A nut 26 is threadedly inserted on one side of the bolt 24, and the size of the nut 26 is fixedly connected to one side of the bolt 24. By using the nut 26, the position of the bolt 24 is reinforced to prevent the bolt 24 from being separated from the threaded tube 23. A connecting rope 27 is fixedly connected to one side of the bolt 24, and the side of the connecting rope 27 away from the bolt 24 is fixedly connected to the fixing belt 22. By using the connecting rope 27, the bolt 24 is connected and fixed to the fixing belt 22 to prevent the bolt 24 from being lost. A control block 28 is fixedly connected to the side of the fixing belt 22 close to the bolt 24, and the control block 28 is in a circular ring shape. By using the control block 28, the contact area between the user and the fixing belt 22 is increased, so that the user can move the fixing belt 22 more easily.

[0034] Figures 1 to 4The seat cushion body 1 shown is provided with an auxiliary device 3 on one side, and the auxiliary device 3 includes four fixing blocks 31, which are fixed at the four corners of the seat cushion body 1, and the surface of the fixing block 31 is clamped with a connecting cloth 32, and one side of the connecting cloth 32 is fixedly connected with an auxiliary pad 33, and the size of the auxiliary pad 33 is adapted to the size of the seat cushion body 1. Before using the seat cushion, the auxiliary pad 33 can be moved to place the auxiliary pad 33 on the surface of the seat cushion body 1, and then the connecting cloth 32 is clamped and fixed with the fixing block 31, and then the position of the auxiliary pad 33 is fixed. By using the auxiliary device 3, the auxiliary pad 33 can be worn instead of the seat cushion body 1, thereby increasing the service life of the seat cushion body 1.

A plurality of anti-sliding blocks 3625 are fixedly connected to one side of the auxiliary pad 33, and the plurality of anti-sliding blocks 3625 are equidistantly arranged on one side of the auxiliary pad 33. By using the anti-sliding blocks 3625, the friction between the auxiliary pad 33 and the user is increased to prevent the user from sliding when contacting the auxiliary pad 33.

[0036] Working principle: When using the inflatable hollow cushion, the air pipe 4 of the cushion body 1 is inflated by an air pump to expand the cushion body 1 to form a hollow cushion for use. When using the cushion body 1, the fixing belt 22 inside the square tube 21 can be moved to make the fixing belt 22 contact the chair, and then the bolt 24 with the anti-sliding block 25 on one side of the fixing belt 22 passes through the fixing belt 22 to reach the inside of the threaded tube 23 on the other side of the fixing belt 22, and then the fixing belt 22 is fixed to the chair, and the bolt 24 is fixed by rotating the nut 26, thereby completing the fixation of the cushion body 1 to the chair and preventing the cushion body 1 from moving. By using the fixing device 2, the cushion body 1 can be fixed to prevent the cushion body 1 from shifting on the chair and affecting the user's sitting posture, thereby improving the use effect of the cushion body 1.

[0037] Before using the seat cushion, the auxiliary pad 33 with the anti-sliding block 36 can be moved so that the auxiliary pad 33 is placed on the surface of the seat cushion body 1, and then the connecting cloth 32 is clamped and fixed to the fixing block 31. At this time, the squeezing block 35 is driven by the spring 34 to squeeze and limit the connecting cloth 32, and then the position of the auxiliary pad 33 is fixed. By using the auxiliary device 3, the auxiliary pad 33 can replace the seat cushion body 1 to be worn, thereby improving the service life of the seat cushion body 1.
