[0027] 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 of 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.

[0028] Please refer to the attached Figures 1 to 5 As shown, a self-balancing base in an embodiment of the utility model comprises a base body 1, two fixed tripods 7 are symmetrically fixedly connected to the inner sides of the base body 1, an electric push rod 8 is fixedly connected to the lower end surface of the fixed tripod 7, the lower end of the electric push rod 8 extends out of the bottom surface of the base body 1 and is fixedly connected to an adjustable supporting foot 2, the four electric push rods 8 are independent of each other and can be independently extended and retracted, when supporting, the inclination angle of the base body 1 is changed by adjusting the extension degree of each electric push rod 8, thereby realizing self-balancing adjustment of the base body 1, ensuring stable support, so that the base can be used on the ground of different flatness, with a wide range of applications, the adjustable supporting foot 2 can be extended and retracted, thereby expanding and reducing the supporting area, ensuring stable support without occupying too much ground space, with comprehensive functions and strong practicality.

[0029] The adjustable supporting foot 2 includes a connecting seat 28, the outer end of the connecting seat 28 is slidably sleeved with a sliding shell 21, a through groove 23 is opened in the middle of the upper end surface of the sliding shell 21, the upper end surface of the connecting seat 28 is fixedly connected with a connecting platform 24 extending out of the through groove 23, the connecting platform 24 is fixedly connected to the electric push rod 8, the sliding shell 21 of the adjustable supporting foot 2 is slidably sleeved with the internal connecting seat 28, and can be retracted and retracted. When the sliding shell 21 is extended, the supporting area can be increased to ensure stable support, and the sliding shell 21 can also be retracted to reduce the floor space and facilitate transportation.

[0030] Guide grooves 25 are provided on both sides of the sliding housing 21, and locking grooves 26 are provided on both sides of the guide grooves 25. The diameter of the locking grooves 26 is larger than the diameter of the guide grooves 25. Elastic locating pins 27 extending out of the guide grooves 25 are connected to both sides of the connecting seat 28. The elastic locating pins 27 are engaged with the locking grooves 26. The elastic locating pins 27 are used to lock the sliding housing 21.

[0031] The elastic locating pin 27 includes a connecting rod 271, the inner end of which extends into the interior of the connecting seat 28 and is fixedly connected to a pressure plate 274. A spring 275 is provided between the pressure plate 274 and the interior of the connecting seat 28. A positioning head 273 is fixedly connected to the middle part of the connecting rod 271, and the positioning head 273 is engaged with the locking groove 26.

[0033] A slide rail 29 is fixedly connected to the middle of the inner bottom of the sliding housing 21 , and the lower end surface of the connecting seat 28 is slidably connected to the slide rail 29 . The sliding housing 21 slides with the connecting seat 28 through the slide rail 29 , and the sliding is stable and smooth.

[0034] The upper end surface of the base body 1 is fixedly connected with a column 5, and the upper end of the column 5 is fixedly connected with a mounting frame 6. The arrangement of the column 5 and the mounting frame 6 facilitates the installation and fixing of the display screen.

[0035] The lower end surface of the seat body 1 is rotatably connected to the inner side of the four adjustable supporting feet 2 with self-locking universal wheels 3. The self-locking universal wheels 3 are convenient for moving the seat body 1 after the adjustable supporting feet 2 are folded, which can improve the flexibility of use.

[0036] An inspection door 4 is fixedly connected to the middle of the front end surface of the seat body 1 by screws. After the inspection door 4 is removed, the internal space of the seat body 1 can be opened to facilitate maintenance of the interior of the seat body 1.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
