Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0026] See also Figure 1-7 The rotatable circular display stand comprises a base 1 and a turntable 2 which are rotatably connected to each other.

[0027] The turntable 2 is located above the base 1, and the base 1 includes a chassis 101 and a mounting column 102.

[0028] The mounting column 102 is located at the top center of the chassis 101, wherein a journal 103 is provided at the top edge of the mounting column 102, on which the inner ring of a tapered roller bearing 104 is fixedly sleeved, and a bearing mounting groove 105 is provided at the top center of the mounting column 102, in which a thrust ball bearing 106 is fixedly installed; a mounting sleeve 201 is provided downward at the bottom center of the turntable 2, and an inner mounting step 202 is provided at the inner wall of the lower end of the mounting sleeve 201, wherein the outer ring of the tapered roller bearing 104 is fixedly installed in the inner mounting step 202, and an inner shaft 203 is provided vertically downward at the inner top of the mounting sleeve 201, and the shaft ring of the thrust ball bearing 106 is fixedly installed at the bottom of the inner shaft 203;

[0029] The turntable 2 is arranged on the turntable 2 by the cooperation and rotation of the thrust ball bearing 106 and the tapered roller bearing 104. At the same time, the thrust ball bearing 106 is used to bear the axial load and plays a role in supporting the turntable 2 in the vertical direction; while the tapered roller bearing 104 is mainly used to bear the radial load and prevent the turntable 2 from moving in the radial direction.

[0030] At the same time, the present invention also includes a driving structure 3 for driving the turntable 2 to rotate.

[0031] Therefore, the driving structure 3 includes a power mechanism 310 and a transmission mechanism 320, wherein the transmission mechanism 320 is composed of at least a turbine 321 and a worm 322 that mesh with each other, wherein the turbine 321 is located outside the mounting sleeve 201 and is fixedly mounted on the bottom of the turntable 2, wherein both ends of the worm 322 are fixedly mounted on the chassis 101 through bearings and bearing seats 323;

[0032] The power mechanism 320 is a stepping motor, which is horizontally arranged on the chassis 101, and the output shaft of the stepping motor is drivingly connected to one end of the worm 322;

[0033] When the stepper motor is in motion, it drives the worm 322 to rotate, and then drives the turntable 2 to rotate through the cooperation of the turbine 321 and the worm 322.

[0034] A horizontal stepper motor is used, and then a transmission mechanism of a worm gear is used. This arrangement ensures that the horizontal height of the driving structure 3 is relatively low, so that the entire rotatable circular display stand can be made thinner;

[0035] In this solution, in order to ensure the structural strength of the turntable 2, a plurality of oblique ribs 204 are provided in a circular array at the bottom of the turntable 2;

[0036] In this solution, an upper outer abutment platform 4 and a lower outer abutment platform 5 are also included, wherein the upper outer abutment platform 4 is located at the bottom edge of the turntable 2, and the outer diameter of the upper outer abutment platform 4 is consistent with the outer diameter of the turntable 2, and the lower outer abutment platform 5 is located at the edge above the chassis 101, and the outer diameter of the lower outer abutment platform 5 is consistent with the outer diameter of the chassis 101; a lower outer gasket 401 is fixedly installed at the bottom of the upper outer abutment platform 4, and an upper outer gasket 501 is fixedly installed at the top of the lower outer abutment platform 5, and the lower outer gasket 401 and the upper outer gasket 501 abut against each other;

[0037] In this solution, an upper inner abutment platform 6 and a lower inner abutment platform 7 are also included, wherein the upper inner abutment platform 6 is located at the bottom edge of the turntable 2, and the upper inner abutment platform 6 is located inside the upper outer abutment platform 4; the lower inner abutment platform 7 is located inside the lower outer abutment platform 5; a lower inner gasket 601 is fixedly installed at the bottom of the upper inner abutment platform 6, and an upper inner gasket 701 is fixedly installed at the top of the lower inner abutment platform 7, and the lower inner gasket 601 and the upper inner gasket 701 abut against each other;

[0038] The lower outer gasket 401, the upper outer gasket 501, the lower inner gasket 601 and the upper inner gasket 701 are all self-lubricating gaskets. The self-lubricating gasket is a prior art, which is basically a solid lubricant such as graphite embedded in a high-strength brass matrix;

[0039] It is also worth noting that the height of the lower outer abutment platform 5 is lower than the height of the lower inner abutment platform 7;

[0040] In this solution, four self-lubricating gaskets are used to support the periphery of the turntable 2 to prevent the edge of the turntable 2 from tilting;

[0041] At the same time, the abutment platforms of different heights can also protect the driving structure 3 from dust to a certain extent;

[0042] like Figure 6 As shown, the stepper motor is also connected with an electric wire, which passes through the lower inner abutment platform 7 and the lower outer abutment platform 5 in sequence and is electrically connected to the mains.

[0043] When the utility model is in operation, the stepping motor drives the worm 322 to rotate, and then drives the turntable 2 to rotate through the cooperation of the turbine 321 and the worm 322, so that the exhibits placed on the turntable 2 rotate to display at multiple angles.
