[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-6 The utility model provides a technical solution: a seat cushion that is easy to adjust the use area, including a main body 10, a cavity 20, a rubber sheet 201, a hole 1 202, a hole 203, an airbag 1 204, a screw rod 30, a gear 301, a rack 302, a telescopic sheet 303, a side plate 304, an airbag 2 305, a pipe 306 and a gasket 40;

[0033] The seat cushion is convenient for ventilation, and the specific implementation method is as follows:

[0034] The main body 10 is configured as a square structure, and a cavity 20 is embedded in the surface of the main body 10, a gasket 40 is fixedly connected to the bottom of the main body 10, a ventilation mechanism is arranged inside the cavity 20, and the ventilation mechanism includes: a rubber sheet 201 is fixedly connected to the inner wall of the cavity 20, and an airbag 1 204 is installed on the inner bottom surface of the cavity 20, and a hole 1 202 is embedded between the cavity 20 and the main body 10, a hole 203 is embedded on the surface of the rubber sheet 201, a pipe 306 is connected between the airbag 1 204 and the airbag 2 305, and the surface of the airbag 1 204 fits with the bottom of the rubber sheet 201.

[0035] The main body 10 is placed on the surface of the seat. At this time, the bottom of the gasket 40 is in contact with most of the surface. The gasket 40 increases the friction between the seat and the main body 10 to prevent the main body 10 from moving. When the air enters the interior of the cavity 20 from the hole 202, the air flows inside the cavity 20, which can cool the gasket 40. At the same time, the heat absorbed by the gasket 40 can enter the cavity 20 through the hole 203. The air drives the heat to flow out of the cavity 20 from the inside of the hole 202, completing the ventilation of the cushion. The airbag 1 204 can be inflated by an external inflation device. Since the airbag 2 305 is squeezed, the gas will not enter the interior of the airbag 2 305, causing the airbag 1 204 to expand and change the hardness of the airbag 1 204. The airbag 1 204 can be inflated to a suitable hardness according to the user's requirements.

[0036] The cushion can adjust the use area, and the specific implementation method is as follows:

[0037] A stretching mechanism is provided on the surface of the main body 10, and the stretching mechanism includes: a screw rod 30 is embedded in the surface of the main body 10, and a gear 301 is fixedly connected to the surface of the screw rod 30, a rack 302 is symmetrically provided on the surface of the gear 301, a side plate 304 is fixedly connected to the end of the rack 302, and a telescopic piece 303 is fixedly connected to the surface of the side plate 304, and the other end of the telescopic piece 303 is fixedly connected to the main body 10, an airbag 2 305 is provided between the side plate 304 and the main body 10, and a pipe 306 is connected to the surface of the airbag 2 305, a thread is provided inside the main body 10, and the main body 10 is threadedly connected to the screw rod 30, the gear 301 is meshedly connected to the rack 302, and the rack 302 is slidably connected to the main body 10, the side plates 304 are symmetrically provided on both sides of the main body 10, and a gasket 40 is provided at the bottom of the side plates 304.

[0038] The screw rod 30 is rotated to rotate inside the main body 10. At this time, the screw rod 30 drives the gear 301 to rotate, and the gear 301 drives the rack 302 on the surface to move inside the main body 10. At this time, the end of the rack 302 pushes the side plate 304 outward, so that the side plate 304 drives the expansion piece 303 to move outward. The expansion piece 303 receives the tension and stretches. At the same time, the side plate 304 drives the airbag 2 305 to move, so that the airbag 2 305 becomes larger and the airbag 2 305 is no longer folded. At this time, the gas inside the airbag 1 204 passes through the pipe 306. Enter the interior of airbag 2 305 to expand airbag 2 305. When the side plate 304 moves to a suitable position, stop rotating the screw rod 30. At this time, airbag 1 204 is inflated through an external inflation device. The gas enters the interior of airbag 2 305 through pipe 306 to expand airbag 2 305 and airbag 1 204 at the same time. When airbag 1 204 and airbag 2 305 are inflated to a suitable hardness, stop inflating. At this time, airbag 2 305 supports the rubber sheet 201, and airbag 2 305 supports the expansion sheet 303.

[0039] Working principle: When using the seat cushion with adjustable use area, hole 1 202, hole 203 and airbag 1 204 are provided to facilitate ventilation of the seat cushion. A telescopic sheet 303, side panel 304 and airbag 2 305 are provided to adjust the use area, thereby increasing overall practicality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
