[0035] In order to make the purpose, technical solutions and advantages of the technical solutions of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure.

[0036] The same reference signs in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0037] Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0038] Embodiment 1

[0039] As Figures 1 to 6 shown, the utility model discloses a rotary transmission structure, comprising: bottom plate 1, wherein Figure 3 The specific structure of the bottom plate 1 is shown, which has a shaft sleeve 2 connected movably or detachably or fixedly; further comprising a support plate 3, which is arranged parallel to the bottom plate 1, Figure 1 And Figure 4 The support plate 3 is shown above the bottom plate 1; the support plate 3 is movably or fixedly connected with the shaft sleeve 2; in the implementation, when the shaft sleeve 2 is movably connected with the bottom plate 1, the support plate 3 can be movably or fixedly connected with the shaft sleeve 2; when the shaft sleeve 2 is fixedly connected with the bottom plate 1, the support plate 3 and the shaft sleeve 2 are movably connected. The support plate 3 also has a support arm 11 connected fixedly or detachably, which is used to mount the table panel on the support arm 11 during use; of course, the support arm 11 is not necessary, and in actual application, the support arm 11 can be deleted, and the table panel is directly mounted on the support plate 3.

[0040] Further comprising a transmission disc 4, as Figure 3 And Figure 4 shown, the transmission disc 4 is mounted between the bottom plate 1 and the support plate 3, and the transmission disc 4 is arranged parallel to the bottom plate 1 and the support plate 3; Figure 6 The transmission disc 4 is shown having a fixedly connected connecting tooth 5; the transmission disc 4 has at least three limiting holes 6 penetrating its upper and lower surfaces. It comprises a first ball 7, which is at least three, and the at least three first balls 7 are movably mounted in the at least three limiting holes 6. It comprises a second ball 8, Figure 4 The second ball 8 is shown as at least three, and the second ball 8 is movably mounted between the transmission disc 4 and the bottom plate 1; the second ball 8 simultaneously abuts against the bottom plate 1 and the transmission disc 4.

[0041] Including motor 9, Figure 3 The motor 9 is shown to have a transmission gear 10 fixedly connected to its shaft. Figure 4 The transmission gear 10 is shown to mesh with the connecting gear 5. The motor 9 drives the transmission gear 10, and the rotation of the transmission disk 4 is achieved through the meshing connection between the transmission gear 10 and the connecting gear 5.

[0042] The rotary transmission structure of this utility model has the following transmission steps: the support plate 3 is used to install the rotating tabletop of the table during use; the base plate 1 is used for fixing. When the motor 9 is started, the transmission gear 10 drives the transmission disk 4 to rotate through the meshing connecting teeth 5. The second ball 8 plays a supporting role, and the first ball 7 passively rotates within the limiting hole 6 of the transmission disk 4. Since the first ball 7 abuts against the support plate 3, the friction of the first ball 7 causes the support plate 3 to rotate passively.

[0043] The rotary transmission structure of this utility model uses a motor 9 to drive a transmission disk 4, and relies on the first ball 7 to indirectly drive the support plate 3 to rotate. At the same time, under the action of the first ball 7, the support plate 3 can stop more smoothly at any time during the rotation. Furthermore, due to the cooperation of the first ball 7, the support plate 3 and the transmission disk 4, the overall friction is smaller and more uniform.

[0044] like Figure 3 As shown, the surface of the base plate 1 has a first annular groove 12; Figure 6 The lower surface of the transmission disc 4 is shown to have a second annular groove 13, as shown in the image. Figure 4 As shown, the first annular groove 12 and the second annular groove 13 are respectively centered on the bushing 2; the first annular groove 12 and the second annular groove 13 have the same diameter; Figure 4 The second ball bearing 8 is shown to be installed in the first annular groove 12 and the second annular groove 13.

[0045] Among them, such as Figure 3 As shown, the support plate 3 has a first connecting hole 14; Figure 1 , Figure 2 The images show the bushing 2 installed within the first connecting hole 14. Further examples include... Figure 1 As shown, a bearing 15 can also be installed in the first connecting hole 14, and the bushing 2 is installed in the bearing 15.

[0046] like Figure 3 and Figure 6As shown, the transmission disk 4 has a second connecting hole 16; the connecting teeth 5 mentioned above have two different implementations, the first being that the connecting teeth 5 are arranged around the edge of the transmission disk 4; the second being that the connecting teeth 5 are arranged around the second connecting hole 16. Figure 6 The second embodiment is shown, in which the connecting teeth 5 surround the edge of the second connecting hole 16.

[0047] like Figure 3 and Figure 6 As shown, the upper surface of the transmission disk 4 has at least three sliding holes 17; see also Figure 4 The sliding hole 17 includes at least three third ball bearings 18, which are installed within the sliding hole 17 and simultaneously abut against the support plate 3. The sliding hole 17 has two implementation schemes: one scheme is that the sliding hole 17 is a countersunk hole that does not penetrate the bottom; the other scheme is that the sliding hole 17 gradually narrows from top to bottom. In either case, the purpose is to ensure that the third ball bearings 18 are installed within the sliding hole 17 and do not fall out downwards. That is, the sliding hole 17 serves to limit the movement of the third ball bearings 18, allowing them to rest against the support plate 3 under the limiting and supporting effect of the sliding hole 17.

[0048] like Figure 3 and Figure 5 As shown, the bushing 2 has a limiting groove 19; it includes a limiting member 20, which is detachably installed in the limiting groove 19; the lower surface of the limiting member 20 abuts against the support plate 3 and / or the bearing 15.

[0049] Example 2

[0050] This embodiment 2 is the same as embodiment 1, so the similarities will not be repeated. The following only describes the differences, which are: the first ball 7 mentioned above is not unique, and the first ball 7 can also be replaced by a columnar structure.
