[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way constitutes a limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] As Figures 1 to 7 shown, the embodiment of the present invention provides a rotating base for connecting with the display component 70. The rotating base includes a base 10, a rotating member 20, and a rotation limiting structure 30. A first wire routing channel 11 is provided on the base 10. The rotating member 20 is rotatably arranged on the base 10 and has multiple adjustment positions. The rotation axis of the rotating member 20 extends in the vertical direction. An installation portion 21 for connecting with the display component 70 is provided on the rotating member 20. A second wire routing channel 22 communicating with the first wire routing channel 11 is also provided on the rotating member 20. The rotation limiting structure 30 is arranged between the base 10 and the rotating member 20 to limit the maximum rotation angle of the rotating member 20 relative to the base 10.

[0034] The rotating base provided in this embodiment is applied, and the rotating base includes a base 10, a rotating member 20 and a rotation limiting structure 30. The display assembly 70 is connected to the mounting portion 21. When the rotating member 20 is rotated, the display assembly 70 can be driven to rotate around the vertical axis of the rotating member 20 together with the rotating member 20, thereby changing the display angle of the display assembly 70. The cable 80 connected to the display assembly 70 is passed through the first wiring channel 11 and the second wiring channel 22 to facilitate the wiring of the cable 80 without being exposed, and a rotation limiting structure 30 is set between the rotating member 20 and the base 10 to limit the maximum rotation angle of the rotating member 20 relative to the base 10, so as to avoid the problem of cable 80 being twisted and damaged due to excessive rotation angle of the rotating member 20 relative to the base 10.

[0035] like Figures 1 to 4 and Figure 6 As shown, the rotating member 20 includes a rod body 23 and a disk body 24, the rod body 23 extends in the vertical direction and is rotatably arranged around its axis through the base 10, the mounting portion 21 is arranged on the rod body 23, the rotation limit structure 30 is arranged between the rod body 23 and the base 10, the disk body 24 is sleeved on the rod body 23 and connected to the rod body 23 or the display assembly 70, and the rotating base also includes a locking structure 40, which is arranged between the disk body 24 and the base 10 to lock the rotating member 20 in any of a plurality of adjustment positions. Specifically, the display assembly 70 is sleeved on the rod body 23 and connected to the mounting portion 21, thereby improving the firmness and stability of the rotation of the display assembly 70, and by arranging the locking structure 40 between the disk body 24 and the base 10, when the display angle of the display assembly 70 is adjusted to the right position, the locking structure 40 can be used to lock the rotating member 20, thereby improving the stability of the display angle of the display assembly 70.

[0036] like Figure 2 As shown, the upper surface of the disk body 24 is provided with reinforcing ribs 241 extending along the radial direction of the rod body 23 and perpendicular to the disk body 24, the upper end of the reinforcing rib 241 is connected to the display assembly 70, and the lower end of the reinforcing rib 241 is connected to the disk body 24 to reduce the contact area between the lower end of the display assembly 70 and the base 10, thereby reducing the rotation resistance.

[0037] like Figures 3 to 6As shown, the locking structure 40 includes an adjustment post 42 and at least two adjustment holes 41. The at least two adjustment holes 41 are provided on the base 10 and are arranged in the circumferential direction of the rod body 23. The adjustment post 42 is movably provided on the disc body 24 and can selectively extend into one of the at least two adjustment holes 41. When it is necessary to adjust the display angle of the display assembly 70, the adjustment post 42 is pulled out from the adjustment hole 41 to disengage from the base 10, and the outer side of the display assembly 70 is forcefully toggled to apply a torque to the display assembly 70, thereby rotating the rotating member 20 to drive the display assembly 70 to rotate around the vertical axis of the rotating member 20 together with the rotating member 20. When the display angle of the display assembly 70 is adjusted in place, the adjustment post 42 is extended into the adjustment hole 41 corresponding to the current display angle to fix the display angle of the display assembly 70. By using the above locking structure 40 in cooperation with the rotating member 20, the manual adjustment of the display angle of the display assembly 70 is realized, and the cost can be reduced compared with the electric adjustment method.

[0038] In this embodiment, the display angle adjustment gradient corresponding to two adjacent adjustment holes 41 is 20°.

[0039] As Figure 1 , Figure 3 and Figure 6 shown, the rotating member 20 includes a rod body 23. The rod body 23 is rotatably disposed through the base 10 around its vertical axis and is connected to the base 10. The mounting portion 21 is provided on the rod body 23. The rotation limiting structure 30 includes a fixing pin 31 and a limiting platform. The fixing pin 31 is disposed through the lower end of the rod body 23 in the transverse direction. The limiting platform is provided on the base 10. The end of the fixing pin 31 can be in a stop fit with the limiting platform in the circumferential direction of the rod body 23. The above rotation limiting structure 30 has the advantages of simple structure, easy assembly and low processing cost. When the rotation angle of the rotating member 20 relative to the base 10 reaches the preset maximum rotation angle, the end of the fixing pin 31 is in a stop fit with the limiting platform in the circumferential direction of the rod body 23 to avoid the problem of cable 80 being damaged due to further rotation of the rotating member 20 relative to the base 10.

[0040] In this embodiment, the rotation limiting structure 30 includes two limiting platforms arranged at equal intervals in the circumferential direction of the rod body 23 to limit the maximum clockwise rotation angle of the rotating member 20 relative to the base 10 to 180°, and limit the maximum counterclockwise rotation angle of the rotating member 20 relative to the base 10 to 180°, to prevent the display assembly 70 from rotating 360 degrees and avoid cable 80 being damaged.

[0041] As Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the rotating base further includes a fastening nut 50. The fastening nut 50 is sleeved on the rod body 23 and is in threaded fit with the rod body 23. The upper end of the fastening nut 50 abuts against the lower surface of the base 10. By using the threaded fit between the fastening nut 50 and the rod body 23 and abutting against the lower surface of the base 10, the rod body 23 is prevented from protruding upward out of the base 10.

[0042] Specifically, the fixing pin 31 is located below the fastening nut 50 and abuts against the fastening nut 50 to prevent the fastening nut 50 from slipping relative to the rod body 23. Anti-slip cards 33 are also provided at both ends of the fixing pin 31 to prevent the fixing pin 31 from protruding relative to the rod body 23, further improving the installation reliability of the rod body 23.

[0043] As Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the rotating base further includes a bearing 60. An installation hole 16 is provided on the base 10. The outer ring of the bearing 60 is arranged in the installation hole 16 and is connected to the base 10. The inner ring of the bearing 60 is sleeved on the rod body 23 and is connected to the rod body 23. By providing the bearing 60, the rotation resistance can be reduced when the rod body 23 rotates relative to the base 10, improving the rotation smoothness and reducing wear.

[0044] Specifically, a through hole for the rod body 23 to pass through is further provided on the base 10. The aperture of the through hole is smaller than the aperture of the installation hole 16 to form a first step surface between the through hole and the installation hole 16. The rod body 23 includes an upper rod body and a lower rod body connected in sequence from top to bottom. The rod diameter of the upper rod body is larger than that of the lower rod body to form a second step surface between the upper rod body and the lower rod body. The lower rod body passes through the through hole. The outer ring of the bearing 60 is sleeved on the lower rod body. The lower end of the bearing 60 abuts against the first step surface, and the upper end of the bearing 60 abuts against the second step surface. The fastening nut 50 is sleeved on the lower rod body and is in threaded fit with the lower rod body. The fixing pin 31 passes through the lower rod body.

[0045] As Figure 5 As shown, a pointing mark 25 is provided on the rotating member 20. At least two angle scales 12 are provided on the upper surface of the base 10. The at least two angle scales 12 are spaced apart in the rotation direction of the rotating member 20. The pointing mark 25 can be selectively aligned with one of the at least two angle scales 12. By observing the alignment state of the pointing mark 25 and the angle scale 12, it is convenient to identify the display angle corresponding to the display component 70 at this time, facilitating the improvement of the adjustment accuracy of the display angle of the display component 70.

[0046] As Figure 6As shown, the installation part 21 includes a first installation clip 211 and a second installation clip 212. The first installation clip 211 and the second installation clip 212 are buckled on the rod body 23 and are detachably connected to the rod body 23. Connection lugs 213 are provided on both the first installation clip 211 and the second installation clip 212. By buckling the first installation clip 211 and the second installation clip 212 on the rod body 23 and connecting them to the rod body 23, the connection between the installation part 21 and the rod body 23 is completed. Then, by using the connection lugs 213 provided on the first installation clip 211 and the second installation clip 212, screws are passed through the connection lugs 213 and connected to the display component 70, so as to conveniently connect the installation part 21, the rod body 23, and the display component 70.

[0047] Specifically, at least two installation parts 21 are arranged on the rod body 23 along its axial direction.

[0048] As Figure 3 shown, the installation part 21 further includes a fastener 214. The fastener 214 includes a stud and a nut. The stud passes through the rod body 23 and the connecting plate of the display component 70, and the nut is sleeved on the stud and is in threaded cooperation with the stud, so as to connect the rod body 23 and the connecting plate by using the stud and the nut.

[0049] As Figure 3 shown, the rotating part 20 includes a rod body 23. The rod body 23 is rotatably passed through the base 10 around its vertical axis and is connected to the base 10. The installation part 21 is arranged on the rod body 23. A hollow hole 231 and a through hole 232 are provided on the rod body 23. The hollow hole 231 penetrates the rod body 23 along the axial direction of the rod body 23, and the through hole 232 is provided on the side wall of the rod body 23 and is communicated with the hollow hole 231. The hollow hole 231 and the through hole 232 together form a second wire routing channel 22. With the above structure, the cable 80 can be passed through the rod body 23 to route the cable 80 along the axial direction of the rod body 23. And when the display component 70 rotates, since the cable 80 is located in the hollow hole 231 of the rod body 23, the wear of the cable 80 can be reduced.

[0050] As Figures 1 to 3As shown, the base 10 includes a base body 13, as well as traveling wheels 14 and first support feet 15 provided on the base body 13. The first support feet 15 and / or the traveling wheels 14 are arranged on the base 10 in a liftable manner. The base 10 has a traveling state and a stationary state. When the base 10 is in the stationary state, the first support feet 15 protrude downward beyond the traveling wheels 14. When the base 10 is in the traveling state, the traveling wheels 14 protrude downward beyond the first support feet 15. When it is necessary to move the rotating base, by raising the first support feet 15 and / or lowering the traveling wheels 14, the base 10 is switched to the traveling state, and the base 10 travels through the traveling wheels 14. When the rotating base moves into place, by lowering the first support feet 15 and / or raising the traveling wheels 14, the base 10 is switched to the stationary state, and the base 10 is supported on the ground by the first support feet 15 to improve the placement stability of the rotating base.

Among them, the cable 80 connected to the display component 70 is passed through the first wire routing channel 11 and the second wire routing channel 22, which is convenient for the cable 80 to be routed without being exposed. And a rotation limit structure 30 is provided between the rotating member 20 and the base 10 to limit the maximum rotation angle of the rotating member 20 relative to the base 10, and to avoid the problem of the cable 80 being damaged due to the over-large rotation angle of the rotating member 20 relative to the base 10.

When the second supporting foot 73 is in the rotating state, the second supporting foot 73 retracts upward relative to the box body 71 and is separated from the base 10. When it is necessary to adjust the display angle of the display component 70, the second supporting foot 73 is switched to the rotating state, the second supporting foot 73 is separated from the base 10, and the adjusting column 42 is pulled out of the adjusting hole 41 to fall off the base 10, and the outer side of the display component 70 is pushed to apply torque to the display component 70, thereby rotating the rotating member 20 to drive the display component 70 to rotate around the vertical axis of the rotating member 20 together with the rotating member 20. When the display angle of the display component 70 is adjusted to the right position, the adjusting column 42 is extended into the adjusting hole 41 corresponding to the current display angle to fix the display angle of the display component 70, and the second supporting foot 73 is switched to the supporting state, and the second supporting foot 73 abuts against the base 10 to improve the stability of the display component 70.

[0054] The display assembly 70 is sleeved on the rod body 23 and connected to the mounting portion 21 , that is, the rod body 23 passes through the display assembly 70 along the vertical direction to improve the firmness and stability of the display assembly 70 in rotation.

[0055] In this embodiment, if Figure 6 As shown, the disc body 24, the reinforcing ribs 241 and the frame 711 adopt an integrally formed structure.
