[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-5 An adjustable anti-slip chair comprises a seat body 1 and a cushion 2 arranged at the top of the seat body 1, the seat body 1 and the cushion 2 are provided with aligned negative pressure holes 201, the bottom end of the seat body 1 is fixedly connected with a relatively arranged support plate 7, the bottom end of the support plate 7 is fixedly connected with a porous base 6, the bottom of the seat body 1 is located at the negative pressure hole 201 and is fixedly connected with a piston cylinder 8, the interior of the piston cylinder 8 is provided with an anti-slip protrusion 3, the bottom end of the anti-slip protrusion 3 is fixedly connected with a driving plate 11, the anti-slip protrusion 3 is a cylinder with a hemispherical top, and the anti-slip protrusion 3 is made of rubber material.

[0021] It should be noted that: according to the needs of the patient, the driving plate 11 can drive the anti-skid protrusion 3 to move upward on the inner side of the piston cylinder 8, so that the anti-skid protrusion 3 extends above the seat cushion 2, thereby increasing the friction of the seat cushion 2 to prevent the patient from sliding down, and the anti-skid protrusion 3 can massage the patient's buttocks and legs;

[0022] The anti-slip protrusion 3 moves downward inside the piston cylinder 8, so that a vacuum is formed inside the piston cylinder 8, which can exert a negative pressure adsorption effect on the patient's buttocks and legs, realize the patient's limiting effect, and prevent the patient from sliding down.

[0023] A driving assembly for driving the driving plate 11 to rise and fall is arranged below the driving plate 11, and the driving assembly includes a cylinder 10 installed on the side wall of the support plate 7, a lower U-shaped adapter block fixedly connected to the output end of the cylinder 10, an upper U-shaped adapter block fixedly connected to the bottom end of the driving plate 11, and a transmission rod 9 rotatably connected between the lower U-shaped adapter block and the upper U-shaped adapter block.

[0024] It should be noted that the cylinder 10 drives the lower U-shaped adapter block to move, thereby driving one end of the transmission rod 9 to move, so that the other end of the transmission rod 9 drives the driving plate 11 to move up and down, thereby controlling the anti-slip protrusion 3 to move up and down inside the piston cylinder 8.

[0025] The surface of the support plate 7 is slidably connected to a relatively arranged U-shaped slider 4, the bottom end of the U-shaped slider 4 is fixedly connected to a plurality of limit pins 5 which are plugged into the internal holes of the porous base 6, the U-shaped slider 4 is fixedly connected to the drive plate 11 through a connecting rod, and the bottom end of the limit pin 5 is provided with anti-slip grooves.

[0026] It should be noted that the U-shaped slider 4 drives the limit pin 5 to move downward and penetrate the holes in the porous base 6 to contact the ground, which can greatly increase the friction between the porous base 6 and the ground, thereby ensuring the stability of the seat body 1 and further ensuring the stability of the patient sitting on the anti-slip chair.

[0027] The cylinder 10 is a prior art, and its model is SCJ50X100-50-S-FA. It can realize the function of driving the lower U-shaped transfer block to move, and will not be described in detail here.

[0028] When the utility model is used, according to the needs of the patient, the cylinder 10 cooperates with the transmission rod 9 to control the driving plate 11 to move up, so that the anti-skid protrusion 3 moves up and extends above the seat cushion 2, thereby increasing the friction of the seat cushion 2 to prevent the patient from sliding down. At the same time, the anti-skid protrusion 3 can massage the patient's buttocks and legs;

[0029] By moving the driving plate 11 downward and driving the anti-sliding block to move to the inside of the piston cylinder 8, a negative pressure environment is formed inside the piston cylinder 8, which can negatively adsorb the patient's buttocks and legs to achieve the patient's limiting function and prevent the patient from sliding down. At the same time, the U-shaped slider 4 drives the limiting pin 5 to move downward and penetrate the holes in the porous base 6 to touch the ground, which can greatly increase the friction between the porous base 6 and the ground, thereby ensuring the stability of the seat body 1 and further ensuring the stability of the patient sitting on the anti-slip chair.
