Especially when the turntable unit rotates and bears a heavy weight, the turntable support base can also achieve stable support, improving the safety of use.

[0033] As Figure 2As shown, in some specific embodiments, the base structure 110 includes a base frame 111 at the bottom, a mounting plate 112 at the top, and base plates 113 arranged along the circumferential direction of the mounting plate 112. The upper end of the base plate 113 is integrally connected to the mounting plate 112, and the lower end of the base plate 113 is integrally connected to the base frame 111.

During the rotation of the turntable unit, the forces on each part of the base body 100 are relatively uniform, so that the structure is stable and firm and not easily damaged. The support interface 101 is arranged at the bottom of the base frame 111, and the mounting structure 120 is arranged on the mounting plate 112. The mounting plate 112 is supported at a certain height through the base frame 111 and the base plates 113 and is spaced from a support surface such as the ground. The structure is simple and light, and a spherical groove space for placing objects is formed under the base structure 110. The base frame 111 is set as a circular ring structure, the strengthening member 210 is arranged along the inner surface of the base frame 111, and the connecting member 220 is connected between the strengthening member 210 and the base frame 111, so that the strengthening structure 200 is arranged close to the bottom of the base body 100, which is more conducive to maintaining the stability of the overall structure of the base body 100 and not easily deforming. Moreover, the base frame 111, the mounting plate 112, and the base plates 113 are set as an integral structure and made of plastic material, and can be integrally processed and formed by production processes such as injection molding and blow molding during production, which is convenient for mass production and no additional screws need to be provided for connection, simplifying the structure.

[0039] As Figure 3 shown, in some specific embodiments, the base body 100 further includes a plurality of foot pad members 114 arranged along the circumferential direction of the base frame 111 at the bottom of the base frame 111. The foot pad members 114 are detachably connected to the base frame 111. The support interface 101 is provided on the bottom surface of the foot pad members 114. The foot pad members 114 are provided with an anti-slip structure to prevent the turntable support base from moving relative to a support surface such as the ground during use, further preventing deformation of the base body 100 and improving the safety during use. The bottom of the foot pad members 114 protrudes outward from the base frame 111 to increase the contact area between the foot pad members 114 and the ground or other installation surfaces, improving the stability of the placement of the base body 100. An extension flange 106 covering the upper side of the foot pad members 114 is protruded outward from the bottom of the base frame 111 for protecting the foot pad members 114 and extending the service life of the foot pad members 114.
