The rotating disc 21 is provided with a rotating disc rotating shaft hole 211, and the first bearing sleeve 22 is provided with a rotating disc fixing ring 221 and a hollow rotating shaft 222 which is coaxial with the rotating disc fixing ring 221 and extends from the inner side of the rotating disc fixing ring 221. The turntable fixing ring 221 is fixedly connected with the rotating disk 21 and coaxially arranged with the turntable rotating shaft hole 211, and the hollow rotating shaft 222 penetrates through the turntable rotating shaft hole 211, the first base bearing 13, the first gasket 15 and the second base bearing 14. The hollow shaft 222 is fitted with the first and second base bearings 13 and 14. The second bearing sleeve 23 is fixed at one end of the hollow rotating shaft 222 penetrating through the base rotating shaft hole 111. The turntable fixing ring 221 and the second bearing sleeve 23 together apply a clamping force to the first base bearing 13, the first washer 15 and the second base bearing 14 in an axial direction parallel to the hollow rotating shaft 222.

It will be appreciated that the display may be removably mounted on the rotary disk 21. The display is especially a commercial display screen (for example, a media playing display screen applied in an office, an information display screen applied in ultrasound, an advertisement display screen applied in a large-scale market, etc.), and the display may also be an electronic device with a display function, such as a flat-panel television, or a liquid crystal display, or a tablet computer, or a display terminal. The display can rotate along with the rotating disk 21 relative to the rotating base 10, so that the display can be in a horizontal screen display state or a vertical screen display state, and various display scenes can be met.

The first bearing sleeve 22 is provided with a rotary table fixing ring 221 fixed on the rotary table 21 and a hollow rotary shaft 222 penetrating through the rotary table rotary shaft hole 211, the second bearing sleeve 23 is fixed at one end of the hollow rotary shaft 222 far away from the rotary table fixing ring 221, the second bearing sleeve 23 and the rotary table fixing ring 221 clamp the first base bearing 13, the first gasket 15 and the second base bearing 14, and the first base bearing 13 and the second base bearing 14 are matched with the hollow rotary shaft 222, so that the rotary bracket 20 is tightly matched with the rotary base 10 in a rotating manner, and the rotating stability of the rotary table 21 relative to the chassis 11 is improved.

In this embodiment, the chassis 11 includes an outer surface 112 and an inner surface 113 opposite the outer surface 112. The outer surface 112 faces the rotary disk 21. The base shaft hole 111 penetrates the outer surface 112 and the inner surface 113. The base plate 11 is a circular plate. The central axis of the chassis 11 is coaxial with the central axis of the base rotating shaft hole 111. The outer surface 112 of the chassis 11 is arranged parallel to the inner surface 113. Both the outer surface 112 and the inner surface 113 are planar. The material of the chassis 11 may be steel. The chassis 11 may be formed via a die-casting process. The chassis 11 may be fixed to a column. The chassis 11 can also be fixed on a wall body or a cabinet body of a decorative cabinet. Preferably, the chassis 11 is fixed to a mobile device, so that the mobile device can drive the chassis 11 to move, and the display installation device 100 can be conveniently applied to a meeting room and other scenes.

Specifically, the chassis 11 includes a supporting plate 114 and a peripheral side plate 115 extending from a periphery of the supporting plate 114. The base shaft hole 111 is disposed on the supporting plate 114. An accommodation space 116 is formed inside the peripheral side plate 115, and the bearing assembly 12 and the second bearing sleeve 23 can be accommodated in the accommodation space 116 to protect the bearing assembly 12 and the second bearing sleeve 23. The chassis 11 can also be mounted on a bracket, a column, or a wall structure by using the peripheral side plate 115, so that the support plate 114 can effectively support the rotating disc 21.

In this embodiment, the first base bearing 13 passes through the base rotation shaft hole 111, and partially protrudes relative to the chassis 11, so as to increase the area of the rotation fit between the rotating base 10 and the hollow rotation shaft 222, and increase the stability of the hollow rotation shaft 222. The first gasket 15 abuts against the side wall of the chassis 11, which is protruded from the first base bearing 13. The outer diameter of the first washer 15 is substantially equal to the outer diameter of the first pedestal bearing 13. The inner diameter of the first washer 15 is larger than the inner diameter of the first base bearing 13, so that a gap exists between the first washer 15 and the hollow rotating shaft 222, and the first washer 15 is prevented from generating rotation resistance on the hollow rotating shaft 222. The first washer 15 is fixed between the first base bearing 13 and the second base bearing 14 to pull apart the distance between the first base bearing 13 and the second base bearing 14, so that the first base bearing 13 and the second base bearing 14 can be respectively and approximately in rotating fit with two ends of the hollow rotating shaft 222, thereby increasing the rotating stability of the hollow rotating shaft 222 and preventing the hollow rotating shaft 222 from shaking relative to the bearing assembly 12. The second base bearing 14 abuts against the side wall of the first gasket 15 away from the first base bearing 13, and the inner diameter of the second base bearing 14 is equal to the inner diameter of the first base bearing 13. The outer diameter of the second seat bearing 14 is equal to the outer diameter of the first washer 15. The first base bearing 13, the first washer 15 and the second base bearing 14 are tightly and stably abutted in sequence, and the first base bearing 13, the first washer 15 and the second base bearing 14 are always firmly fixed on the chassis 11, so that the chassis 11 and the bearing assembly 12 are prevented from shaking, and the inner portion of the first base bearing 13 and the inner portion of the second base bearing 14 can provide a stable bearing effect for the hollow rotating shaft 222. The inner peripheral side wall of the first pedestal bearing 13 and the inner peripheral side wall of the second pedestal bearing 14 are in rotating fit with the outer peripheral side wall of the hollow rotating shaft 222, so that the hollow rotating shaft 222 is kept in coaxial rotating fit with the first pedestal bearing 13 and the second pedestal bearing 14. Of course, in other embodiments, the bearing assembly 12 may further include a second washer secured between the second pedestal bearing 14 and the third pedestal bearing, and a third pedestal bearing rotationally engaged with the hollow shaft 222.

In the present embodiment, the rotary plate 21 is substantially in the shape of a rectangular plate. The rotary plate 21 includes a bezel 212 and an inner plate 213 integrated with the bezel 212. The inner plate 213 is disposed in the bezel 212, and the inner plate 213 forms a protruding boss protruding from the bezel 212. The inner plate 213 has an outer convex surface and an inner concave surface opposite to the outer convex surface. The outer convex surface faces the front surface of the chassis 11. The turntable rotating shaft hole 211 penetrates through the inner concave surface and the outer convex surface. The inner diameter of the rotary disc rotary shaft hole 211 is smaller than that of the base rotary shaft hole 111, so that the stability of the rotary disc 21 and the first bearing sleeve 22 is increased conveniently. The frame 212 can enhance the stability of the rotating disc 21, increase the carrying capacity of the rotating disc 21 for the display, and facilitate the rotating disc 21 bearing the display with heavy weight. Optionally, a mounting clip 214 and a fixing upright 215 opposite to the mounting clip 214 are disposed on a surface of the inner plate 213 of the rotating disk 21, the surface being away from the chassis 11, and the mounting clip 214 and the fixing upright 215 are used to fixedly connect a back of the display. The rotating disc 21 is made of steel. Of course, in other embodiments, the rotating disc 21 may be in the shape of a circular plate.

In this embodiment, the turntable fixing ring 221 is attached to the inner concave surface on the outer peripheral side of the rotating shaft hole. The turntable fixing ring 221 is circumferentially provided with a plurality of screw holes, so that the turntable fixing ring 221 can be stably connected with the rotating disc 21 through a plurality of screws. The inner diameter of the turntable fixing ring 221 is smaller than the turntable rotating shaft hole 211, so that the hollow rotating shaft 222 can conveniently penetrate through the turntable rotating shaft hole 211. The turntable fixing ring 221 tightly abuts against a surface of the rotating disc 21 away from the chassis 11. The hollow rotating shaft 222 passes through the rotating shaft hole 211, the first base bearing 13, the first washer 15 and the second base bearing 14. The peripheral side wall of the hollow rotating shaft 222 is rotatably matched with the inner side wall of the first base bearing 13 and the inner side wall of the second base bearing 14. The first and second base bearings 13 and 14 limit the movement of the hollow rotating shaft 222 along the rotating plane. The turntable fixing ring 221 and the second bearing sleeve 23 clamp the first base bearing 13 and the second base bearing 14 to limit the rotation bracket 20 to move relative to the rotation base 10 along a direction parallel to the hollow rotation shaft 222, so as to ensure that the rotation bracket 20 can stably rotate relative to the rotation base 10. The end surface of the hollow rotating shaft 222 is approximately flush with the end surface of the second base bearing 14, so that the second bearing sleeve 23 is stably connected with the end of the hollow rotating shaft 222, and the second bearing sleeve 23 can effectively limit the position of the second base bearing 14. The inner diameter of the second bearing sleeve 23 is smaller than that of the hollow rotating shaft 222, so that the stability of the second bearing sleeve 23 and the hollow rotating shaft 222 is improved. The outer diameter of the second bearing sleeve 23 is larger than the outer diameter of the second base bearing 14, so that the second bearing sleeve 23 can effectively limit the second base bearing 14.

It can be understood that the inside of the first bearing sleeve 22 is communicated with the inside of the second bearing sleeve 23, and the first bearing sleeve 22 and the second bearing sleeve 23 jointly penetrate through the rotating disc 21 and the chassis 11, so that a conductive cable which can be electrically connected with a display can conveniently penetrate through the inside of the first bearing sleeve 22 and the inside of the second bearing sleeve 23, a display fixed on the rotating disc 21 can conveniently penetrate through the first bearing sleeve 22 and the second bearing sleeve 23, and the display can still effectively rotate.

Further, the rotating base 10 further includes a bearing fixing member 16 fixed to the chassis 11, the bearing fixing member 16 is provided with a bearing fixing cylinder 161 coaxial with the base rotating shaft hole 111, and the first base bearing 13, the first washer 15 and the second base bearing 14 are fixed in the bearing fixing cylinder 161 and are tightly fitted to an inner wall of the bearing fixing cylinder 161.

In this embodiment, one end of the bearing fixing cylinder 161 is fixed to the chassis 11, and the other end is disposed away from the chassis 11. The central axis of the bearing fixing cylinder 161 is coaxial with the central axis of the base rotary shaft hole 111. One end of the bearing fixing cylinder 161 is inserted into the base rotation shaft hole 111 to maintain the stability of the bearing fixing cylinder 161 and the chassis 11. The end surface of the bearing fixing cylinder 161 inserted into the base rotation shaft hole 111 is flush with the surface of the chassis 11 facing the rotation plate 21. An end surface of the first base bearing 13 far away from the first gasket 15 is flush with an end surface of the bearing fixing cylinder 161, so that the chassis 11, the bearing fixing cylinder 161 and the first base bearing 13 are effectively stable. The bearing fixing cylinder 161 effectively supports the first base bearing 13 and the second base bearing 14, and ensures the stability of the rotating base 10. The bearing fixing cylinder 161 is detachably connected with the chassis 11, so that the bearing assembly 12 and the chassis 11 can be conveniently detached and maintained, and the service life of the rotating base 10 is prolonged. The bearing fixing cylinder 161 can increase the bearing area of the chassis 11 to the bearing assembly 12, and facilitate the setting of two or more base bearings on the rotating base 10, thereby increasing the area of the rotating fit between the rotating base 10 and the hollow rotating shaft 222, further increasing the bearing performance of the rotating base 10 to the hollow rotating shaft 222, and enabling a heavy display to be fixed on the turntable. Of course, in other embodiments, the bearing fixing member 16 may be integrally formed with the chassis 11, that is, the bearing fixing cylinder 161 extends from the base rotating shaft hole 111.

Further, the bearing fixing member 16 is provided with a bearing limiting ring 162 at one end of the bearing fixing cylinder 161 away from the turntable fixing ring 221, the rotating base 10 further includes a bearing pressing plate 17 fixed on one surface of the base plate 11 away from the turntable fixing ring 221, and the bearing pressing plate 17 and the bearing limiting ring 162 clamp and stabilize the first base bearing 13, the first washer 15 and the second base bearing 14.

In this embodiment, the bearing retainer ring 162 is provided integrally with the bearing fixing cylinder 161. The inner diameter of the bearing retainer ring 162 is smaller than the inner diameter of the bearing fixing cylinder 161. The interior of the bearing retainer 162 may allow the conductive cables of the display to pass through. The bearing retainer 162 is tightly abutted against the outer portion of the second base bearing 14 toward an inner end surface of the chassis 11. The bearing retainer 162 limits the second base bearing 14 to move in a direction away from the chassis 11 along an axial direction parallel to the base rotation axis hole 111.

Specifically, the bearing fixing member 16 is provided with a fixing piece 163 fixedly connected to the chassis 11 at an outer side of an end of the bearing fixing cylinder 161 close to the base rotation shaft hole 111, and the fixing piece 163 is fixed to a surface of the chassis 11 facing the rotation disc 21. The fixing piece 163 and the bearing pressing piece 17 clamp and fix the chassis 11 at the outer periphery of the base rotating shaft hole 111. The screw holes of the fixing piece 163 are opposite to the screw holes of the bearing pressing piece 17, so that the fixing of the fixing piece 163, the base plate 11 and the bearing pressing piece 17 is increased. The bearing pressing plate 17 is integrally provided with the bearing fixing cylinder 161 to secure the structural strength of the bearing fixing member 16. The outer side portion of the fixing piece 163 is stacked with the base plate 11 and is fixedly connected with the base plate 11 by a plurality of screws. The inner side portion of the fixing piece 163 is opposite to the base rotating shaft hole 111, the inner side portion of the fixing piece 163 tightly abuts against the end surface of the bearing fixing cylinder 161 and the end surface of the first base bearing 13, and the fixing piece 163 limits the first base bearing 13 to move along the direction parallel to the axial direction of the base rotating shaft hole 111 and beyond the direction away from the second base bearing 14. The inner portion of the securing tab 163 is closely fitted with the outer portion of the first mount bearing 13. The inner side of the fixing piece 163 is spaced from the hollow rotating shaft 222, so as to prevent the fixing piece 163 from contacting the hollow rotating shaft 222, and the wear resistance and the higher smoothness of the first base bearing 13 and the second base bearing 14 are utilized to ensure the smooth rotation of the hollow rotating shaft 222 and the bearing assembly 12. The stabilizing piece 163 is located between the rotating disc 21 and the chassis 11, and a gap exists between the stabilizing piece 163 and the rotating disc 21, so that the stabilizing piece 163 is prevented from interfering with the rotation of the rotating disc 21 relative to the chassis 11.

Further, an annular groove 231 is formed in one surface, facing the chassis 11, of the second bearing sleeve 23, the rotating bracket 20 further includes a damping ring 24 fixed to the annular groove 231, and the damping ring 24 is in damping fit with an end portion, far away from the second pedestal bearing 14, of the bearing retainer 162.

In this embodiment, the annular groove 231 is located at the second bearing sleeve 23 approximately opposite to the outer portion of the second mount bearing 14. The damping ring 24 is a plastic ring. The damping ring 24 is fixed in the annular groove 231 and abuts against the bearing retainer 162, so that friction is generated between the bearing retainer 162 and the damping ring 24. During the rotation of the rotating disc 21 relative to the chassis 11, the damping ring 24 provides a damping force for the rotation of the bearing retainer 162, so that the damping force exists during the rotation of the rotating disc 21 relative to the chassis 11. The damping effect of the damping ring 24 on the bearing retainer 162 can make the rotating disc 21 keep a relatively static state with the chassis 11 when the rotating disc 21 rotates relative to the chassis 11 without a driving force, so that the display can keep a hovering state and avoid the display from being influenced by gravity to drive the rotating disc 21 to have a large impact effect with the chassis 11. Specifically, the open end of the annular groove 231 is provided with a chamfer, and the end of the bearing limit ring 162 is provided with a chamfer, so that the bearing limit ring 162 is prevented from contacting with the second bearing sleeve 23, and the mutual rotation smoothness of the rotary disc 21 and the chassis 11 is ensured. Of course, in other embodiments, the damping ring 24 may be a silicone gasket, a rubber gasket, or an elastic gasket.

Further, the rotating bracket 20 further includes a second washer 25 fixed to the annular groove 231, and the second washer 25 tightly abuts against the damping ring 24 and the second bearing sleeve 23.

In the present embodiment, the thickness of the second gasket 25 is smaller than the thickness of the damping ring 24. The second washer 25 is located at the bottom of the annular groove 231, so that the tightness of the damping ring 24 and the bearing retainer 162 is higher. The second washer 25 may be a steel ring. The second washer 25 is fixed between the damping ring 24 and the second bearing sleeve 23, so that the stability of the damping ring 24 and the bearing sleeve is increased, and the damping ring 24 is prevented from moving relative to the second bearing sleeve 23 to cause abrasion to the second bearing sleeve 23. The damping ring 24 is pressed by the second washer 25 to more closely abut against the end of the bearing fixing member 16, so that the matching structure of the rotating base 10 and the rotating bracket 20 is more compact. Of course, in other embodiments, a plurality of second washers 25 may be further disposed in the annular groove 231 to increase the contact force of the damping ring 24 against the bearing retainer 162.

Further, the first bearing sleeve 22 is provided with a limit boss 223 at one end of the hollow rotating shaft 222 close to the turntable fixing ring 221 along the circumferential direction, and the limit boss 223 limits one end of the first base bearing 13 close to the hollow rotating shaft 222 to move along the direction parallel to the hollow rotating shaft 222.

In this embodiment, the limit projection 223 extends from the inner portion of the dial fixing ring 221 toward the second bearing sleeve 23. The limit boss 223 is closely and rotatably fitted with the inner side of the first base bearing 13. The limiting boss 223 strengthens the stability of one end of the first bearing sleeve 22 close to the rotating disc 21, and ensures that the first bearing sleeve 22 and the rotating disc 21 are stable in structure. The distance from the limit boss 223 to the end surface of the hollow rotating shaft 222 far away from the rotating disk 21 is slightly smaller than the sum of the thickness of the first base bearing 13, the thickness of the first washer 15 and the thickness of the second base bearing 14, so that after the second bearing sleeve 23 is locked at the end of the hollow rotating shaft 222, the second bearing sleeve 23 and the limit boss 223 can clamp the second base bearing 14 and the first base bearing 13, so as to ensure that the first base bearing 13 and the second base bearing 14 can be effectively in rotating fit with the hollow rotating shaft 222.

Specifically, the first bearing sleeve 22 is provided with a sleeve fixing ring 224 on the outer side of the hollow rotating shaft 222 near one end of the second bearing sleeve 23 along the circumferential direction, and the inner side portion of the second bearing sleeve 23 is fixedly connected to the sleeve fixing ring 224 and limits the movement of the second base bearing 14 near one end of the hollow rotating shaft 222 along the direction parallel to the hollow rotating shaft 222. The inner side of the second bearing sleeve 23 is fastened to the end of the first bearing sleeve 22 by a plurality of screws. In other embodiments, a threaded portion may be provided at an end of the first bearing sleeve 22, and the second bearing sleeve may be screwed to the threaded portion, so that the second bearing sleeve 23 is screwed to the end of the first bearing sleeve 22, and then the pressing force may be applied to the second base bearing 14.

In the present embodiment, the first pedestal bearing 13 has a substantially i-shaped cross section. The first pedestal bearing 13 includes a first beam 131 closely fitted to the hollow rotating shaft 222, a second beam 132 distant from the hollow rotating shaft 222, and a vertical beam 133 connected between the first beam 131 and the second beam 132. The structure of the second base bearing 14 is substantially the same as the structure of the first base bearing 13, and therefore, the detailed description thereof is omitted. The first beam 131 of the first base bearing 13 is closely and rotatably matched with the hollow rotating shaft 222 and the limit boss 223. The second cross beam 132 of the first pedestal bearing 13 is tightly and stably matched with the bearing pressing sheet 17 and the bearing fixing cylinder 161. The first beam 131 of the second base bearing 14 is closely and rotatably matched with the hollow rotating shaft 222 and the second bearing sleeve 23. The second beam 132 of the second pedestal bearing 14 is tightly and stably matched with the bearing retainer ring 162 and the bearing fixing cylinder 161. The first base bearing 13 and the second base bearing 14 have grooves at both ends, so that the weight can be reduced, and the weight of the display mounting device 100 is reduced, thereby facilitating the movement of the display mounting device 100. By utilizing the smaller weight of the first base bearing 13 and the second base bearing 14, the displacement of the central axes of the first base bearing 13 and the second base bearing 14 and the central axis of the base rotating shaft hole 111 caused by the influence of gravity on the first base bearing 13 and the second base bearing 14 is avoided, and the stability of the bearing assembly 12 and the chassis 11 is improved.

Further, the rotating base 10 includes a rear cover 18 covering the chassis 11, an accommodating space 116 is formed between the chassis 11 and the rear cover 18, the second bearing sleeve 23 is accommodated in the accommodating space 116, and the accommodating space 116 is communicated with the inside of the hollow rotating shaft 222. In the present embodiment, the peripheral edge of the rear cover 18 is fixedly connected to the end of the peripheral side plate 115. The rear cover 18 covers the opening of the receiving space 116, so that the second bearing sleeve 23 and the bearing assembly 12 are effectively protected.
