In actual use, it is inconvenient to adjust the height to better meet the actual installation needs. In addition, when the roller-type footrest structure is actually used, it is difficult to avoid rolling of the roller, thereby affecting the user's game operation. In addition, during the long-term use of the roller, the direct force of gravity on the roller can easily cause the roller to be damaged, thereby affecting the service life of the footrest.

[0018] 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.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: an adjustable support footrest, including a support foot 1, a screw rod 2 is connected to the support foot 1, a mounting frame 3 is slidably connected to the screw rod 2, the mounting frame 3 and the screw rod 2 are fixed by a second nut 4, a support rod 5 is also obliquely fixed on the lower end surface of the mounting frame 3, and a fixing tube 6 is also fixed on the inner side of the support foot 1.

[0020] The screw rod 2 and the support leg 1 are nested and connected, and the screw rod 2 and the support leg 1 can be locked by a first nut 201; a through hole 301 is provided on the mounting frame 3, and two mounting holes 302 are also provided on the mounting frame 3; a connecting ring 501 is fixed to the right end of the support rod 5, and the connecting ring 501 and the screw rod 2 are slidably connected;

[0021] When using the adjustable support footrest, Figure 1-Figure 3 As shown, when installing the footrest, first adjust the height of the mounting frame 3 according to actual needs. The height adjustment of the mounting frame 3 can be achieved through the sliding action between the mounting frame 3 and the connecting ring 501 and the screw rod 2. After the adjustment is completed, the mounting frame 3 can be locked by the second nut 4 to ensure the stability of the mounting frame 3. Then, the mounting frame 3 and the seat are installed. The mounting frame 3 and the seat can be assembled by the mounting holes 302 and the bolts. After the assembly is completed, the gravity of the seat directly acts on the mounting frame 3, and the supporting action of the support rod 5 on the mounting frame 3 can prevent the mounting frame 3 from being deformed or damaged.

[0022] An annular plate 101 is also fixed to the inner side of the support leg 1, and an anti-skid pad 102 is bonded and fixed to the lower end surface of the annular plate 101, and the lower end surface of the anti-skid pad 102 is lower than the lower end surface of the support leg 1; a sliding rod 7 is slidably connected to the fixed cylinder 6, and the fixed cylinder 6 and the sliding rod 7 are distributed in four groups at equal angles about the center of the circle of the support leg 1; a rolling ball 701 is installed on the lower end surface of the sliding rod 7, and the lower end surface of the ball 701 is lower than the lower end surface of the anti-skid pad 102; one end of a spring 8 is fixed to the upper end of the sliding rod 7, and the other end of the spring 8 is fixed in the fixed cylinder 6;

[0023] After the footrest is installed, Figure 1-Figure 4 As shown, at this time, under the action of the gravity of the seat, the lower end surface of the ball 701 is always lower than the lower end surface of the anti-slip pad 102, so that the ball 701 is in direct contact with the ground. Through the rolling action of the ball 701, the seat can be easily moved for position adjustment. When someone sits on the seat, under the action of the human body's gravity, the ball 701 can be subjected to force, so that the slide rod 7 slides into the fixed tube 6, so that the spring 8 is forced to contract until the lower end surface of the ball 701 is flush with the lower end surface of the anti-slip pad 102, so that the lower end surface of the anti-slip pad 102 is in contact with the ground to achieve an anti-slip effect, effectively preventing the seat from sliding after someone sits on it. This is the working principle of the adjustable support footrest.

[0024] 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.
