[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0022] Embodiment: Please refer to Figs. 1 to 4 A stage lamp rotating base, comprising a base body 1, the top of the base body 1 is provided with a Y-axis 101, the upper end of the Y-axis 101 is fixedly provided with a supporting arm 102, the supporting arm 102 is provided with an X-axis 103, and a stage lamp is fixed on the X-axis 103, so that the stage lamp can freely rotate at multiple angles through cooperation of the Y-axis 101 and the X-axis 103, which is prior art and will not be described here.

[0023] The embodiment further comprises a fixing plate 2, two extension mounting frames 3 and two positioning fixing mechanisms 5. The fixing plate 2 is fixed to the bottom of the base body 1, and the outer edge of the fixing plate 2 is larger than the outer edge of the base body 1, so as to facilitate installation of other components.

[0024] The extension mounting frame 3 will be described in detail as follows:

[0025] The two extension mounting frames 3 are located on the left and right sides of the fixing plate 2, and a contraction groove 4 matched with each extension mounting frame 3 is formed in the bottom of the fixing plate 2. The extension mounting frame 3 can be extended in the contraction groove 4, so as to adjust the size of the contact range. Specifically, the extension mounting frame 3 comprises two extension plates 301 which are parallel and connected to the contraction groove 4 through sliding, a mounting plate 302 is fixed to the outer end of each extension plate 301, a plurality of mounting holes 303 are formed in the mounting plate 302, and the mounting plate 302 is fixed to the ground, ceiling or wall through cooperation of external bolts and the mounting holes 303.

[0026] In the embodiment, the lower surface of the mounting plate 302, the lower surfaces of the extension plates 301 and the lower surface of the fixing plate 2 are flush, so that the mounting plate 302, the extension plates 301 and the fixing plate 2 can be in contact with the ground, ceiling or wall at the same time, the contact area is large, and the installation is stable.

[0027] In addition, the inner end of the extension plate 301 is fixedly provided with a sliding block 6, and a limiting sliding groove 7 for sliding of the sliding block 6 is formed in the contraction groove 4. When the extension mounting frame 3 is extended or retracted, the sliding block 6 can slide in the limiting sliding groove 7, so that the extension plate 301 will not be separated from the contraction groove 4.

[0028] The positioning fixing mechanism 5 will be described in detail as follows:

[0029] Two positioning and fixing mechanisms 5 are arranged on the top of the fixed plate 2 and correspond to each of the extension mounting frames 3, and are used to fix the extension mounting frame 3 and the fixed plate 2. Specifically, the positioning and fixing mechanism 5 comprises a portal frame 501 fixed on the top of the fixed plate 2, a connecting rod 502 corresponding to each of the extension plates 301 is movably arranged on the portal frame 501 in parallel and at intervals, a limiting plate 503 is fixed on the upper end of each of the connecting rods 502, and is used to prevent the connecting rod 502 from over displacement. A positioning plug rod 504 movably passes through the fixed plate 2 in the vertical direction at the lower end of each of the connecting rods 502, a compression spring 505 is sleeved on each of the connecting rods 502 and is located between the positioning plug rod 504 and the portal frame 501, the compression spring 505 always applies a downward elastic force to the positioning plug rod 504, so that the positioning plug rod 504 can pass through the fixed plate 2. A plurality of positioning holes 8 are arranged on each of the extension plates 301 at equal intervals along the length direction. After the extension plate 301 is extended or retracted, the positioning plug rod 504 can be inserted into the corresponding positioning hole 8, so that the position of the extension plate 301 is fixed, and then the extension mounting frame 3 can be fixed with the fixed plate 2.

[0030] The working principle is as follows:

[0031] When it is needed to install the device on the ground, the extension plate 301 is completely received in the retraction groove 4, the position of the extension plate 301 is fixed by the cooperation of the positioning plug rod 504 and the positioning hole 8, and finally the device can be installed on the ground by the cooperation of the external bolt and the mounting hole 303. In this way, the overall structure of the device is small, and it is not easy to affect the surrounding environment.

[0032] When it is needed to install the device on the ceiling or wall, the limiting plate 503 is first lifted upward, the positioning plug rod 504 is separated from the positioning hole 8, and then the extension plate 301 is pulled out from the retraction groove 4, so that the contact range of the device with the ceiling or wall is increased to improve the stability after installation. After adjustment, the limiting plate 503 is loosened, the positioning plug rod 504 is inserted into the corresponding positioning hole 8 under the driving of the compression spring 505, so that the extension plate 301 is fixed, and finally the device can be installed on the ceiling or wall by the cooperation of the external bolt and the mounting hole 303.
