[0050] As shown in Figures 11-15 the first connecting assembly 50 includes a rotating assembly 5a and a clamping assembly 5b in an embodiment; the rotating assembly 5a can rotate the bearing assembly 20 to switch between the vertical placement state and the horizontal placement state, facilitating the installation or removal of the bearing assembly 20; the clamping assembly 5b can limit the rotation of the rotating assembly 5a when the bearing assembly 20 is horizontally placed, that is, when the rotating assembly 5a rotates to the horizontal placement state, the clamping assembly 5b can limit the rotation of the rotating assembly 5a, thereby facilitating the installation or removal of the bearing assembly 20.

[0051] As shown in Figures 11-15 optionally, the rotating assembly 5a includes a driving part 5a1 and a support frame 5a2, the upper side of the support frame 5a2 is rotatably connected with the upper side of the main body, and the driving part 5a1 is used to drive the upper side of the support frame 5a2 to rotate around the rotating connection position. The support frame 5a2 is driven to rotate by the driving part 5a1, thereby realizing the transformation of the support frame 5a2 between the vertical placement and the horizontal placement, thereby facilitating the installation or removal of the bearing assembly 20.

[0052] As shown in Figures 11-14 optionally, the driving part 5a1 includes a first rotating shaft 511, a first driving part 512 and a second driving part 513 provided on the main body; the bearing assembly 20 can drive the first rotating shaft 511 to rotate through the first driving part 512, and the first rotating shaft 511 drives the support frame 5a2 to rotate through the second driving part 513. Through the transformation of the bearing assembly 20 to the first rotating shaft 511 and then to the support frame 5a2, the driving force required for rotation can be reduced, and the driving difficulty can be reduced.

[0053] As shown in Figures 11-14 optionally, the first driving part 512 includes a first gear 12n and a first rack 12m, the first gear 12n is provided on the first rotating shaft 511, and the first rack 12m is provided on the bearing assembly 20; the movement of the first rack 12m can drive the first rotating shaft 511 to rotate through the first gear 12n. Through the cooperation of the first gear 12n and the first rack 12m, the stability during driving can be effectively ensured.

[0054] As shown in Figures 11-15As shown, optionally, the second driving member 513 comprises a second gear 13n, a third gear 13m and an inner ring gear 13x, the second gear 13n is arranged on the first rotating shaft 511, the inner ring gear is arranged on the support frame 5a2, the third gear 13m is located between the second gear 13n and the inner ring gear 13x, the second gear 13n, the third gear 13m and the inner ring gear 13x constitute a planetary gear set, and the first rotating shaft 511 drives the inner ring gear 13x to rotate through the second gear 13n and the third gear 13m, thereby driving the support frame 5a2 to rotate, which reduces the strength of the first rotating shaft 511 driving the support frame 5a2 to rotate, facilitating the installation and disassembly of the bearing assembly 20.

[0055] As shown in Figures 11-12 , Figure 15 As shown, optionally, the clamping assembly 5b comprises a sliding rod 5b1, a push block 5b2, a fourth clamping groove 5b3 and a fourth elastic member 5b4, the sliding rod 5b1 is arranged on both sides of the support frame 5a2, the push block 5b2 is fixed on the side of the sliding rod 5b1 away from the first rotating shaft 511, the fourth elastic member 5b4 can drive the sliding rod 5b1 to move towards the side close to the first rotating shaft 511, and the fourth clamping groove 5b3 is arranged on the main body 10. When the support frame 5a2 is rotated to be placed horizontally, the sliding rod 5b1 is fixed in the fourth clamping groove 5b3 under the action of the fourth elastic member 5b4, so that the support frame 5a2 is fixed to the horizontal placement position. When the fixation of the sliding rod 5b1 needs to be released, that is, when the bearing assembly 20 is installed with the support frame 5a2, the bearing assembly 20 will push the push block 5b2 to move away from the first rotating shaft 511, and then the sliding rod 5b1 is separated from the fourth clamping groove 5b3, and the first rotating shaft 511 can subsequently rotate the support frame 5a2 to be arranged vertically under the action of the first rack 12m.

[0056] As shown in Figure 13 , optionally, the bearing assembly 20 is provided with a first stop member 5c, and the first rotating shaft 511 is provided with a second stop member 5d. When the first rack 12m is separated from the first gear 12n, the sliding rod 5b1 is just positioned opposite the fourth clamping groove 5b3, that is, the sliding rod 5b1 can be inserted into the fourth clamping groove 5b3. When the first rack 12m is separated from the first gear 12n, the first stop member 5c and the second stop member 5d contact to block the rotation of the first rotating shaft 511, preventing the first rotating shaft 511 from rotating after the first rack 12m is separated from the first gear 12n, which causes the sliding rod 5b1 to be misaligned with the fourth clamping groove 5b3, resulting in the problem that the support frame 5a2 cannot be fixed.

[0057] As shown in Figures 11-12 , Figure 15As shown, optionally, the third positioning member 5f is installed on the side of the push block 5b2 away from the first rotating shaft 511, and the positioning hole 5g is arranged on the lower side of the main body.

[0089] As shown in the figure, Figures 1-5 Optionally, the second positioning member 6b2 is spherical or ellipsoidal, which can make the first positioning member 6b1 and the second positioning member 6b2 not separated under the adsorption of strong magnet, and can reduce the rotation resistance when rotating, and ensure the stability of the second positioning member 6b2 when rotating.

[0090] Optionally, the bearing assembly 20 is provided with a second rotating shaft 6c, and a second positioning member 6b2 is installed on the second rotating shaft 6c, and the axis of the second rotating shaft 6c passes through the center of the second positioning member 6b2; when the second rotating shaft 6c rotates, it drives the second positioning member 6b2 to rotate.

[0094] like Figures 1-5 As shown, optionally, the driving member 6e faces the LED display assembly 30.

A second elastic member 6f is provided on the side of the driving member 6e away from the LED display assembly 30. The second elastic member 6f gives the driving member 6e a force to move towards the LED display assembly 30. The force of the driving member 6e moving towards the LED display assembly 30 can cause the driving wheel 6d to rotate, so that the second positioning member 6b2 rotates to the same magnetic pole as the first positioning member 6b1. 1. The magnetic poles are opposite; the LED display assembly 30 is provided with a clearance hole, and the first positioning member 6b1 is provided in the clearance hole.

[0095] Optionally, the second rotating shaft 6c is provided with a delaying element (not shown in the figure), which can slow down the driving speed of the driving element 6e when the second elastic element 6f pushes the driving element 6e to move; so that the second positioning element 6b2 is delayed in attracting the first positioning element 6b1 after rotation, ensuring sufficient operation time.

[0096] Preferably, the delaying element can be a liquid retarder installed at the second rotating shaft 6c.

[0097] Preferably, the delaying element is a friction layer provided on the second rotating shaft 6c, which slows down the rotation of the second rotating shaft 6c driven by the driving element 6e through friction.

[0101] As shown in the figure, Figures 1-5 when dismounting is needed, the LED display assembly 30 is adsorbed by the negative pressure suction cup, then the LED display assembly 30 is pressed, the LED display assembly 30 is driven by the driving part 6e to rotate the second positioning part 6b2, the second positioning part 6b2 is rotated to the same magnetic pole as the first positioning part 6b1, the repulsion of the second positioning part 6b2 enables the first positioning part 6b1 to move away from the second positioning part 6b2, then the negative pressure suction cup is dragged to make the LED display assembly 30 move away from the bearing assembly 20; at this time, the LED display assembly 30 is separated from other LED display assemblies 30 on the circumferential side, and the second connector 80 of the LED display assembly 30 is separated; during the movement of the LED display assembly 30, the clamping block a22 always moves in the third clamping groove 11c, so that the clamping block a22 is not blocked; but at this time, the LED display assembly 30 will not be separated under the action of the first clamping groove 11a, if no subsequent operation is taken, when the second positioning part 6b2 is rotated to the opposite magnetic pole of the first positioning part 6b1 under the action of the second elastic part 6f, the LED display assembly 30 will be attracted and fixed by the strong magnet again, in this way, the problem of accidental removal can be prevented; if the LED display assembly 30 needs to be removed, the LED display assembly 30 needs to be pulled to move away from the bearing assembly 20, so that the LED display assembly 30 moves to be not flush with the adjacent LED display assembly 30, then the LED display assembly 30 is rotated, the clamping block a22 is moved along the first clamping groove 11a to the second clamping groove 11b, and finally the LED display assembly 30 is removed.

[0102] When mounting is needed, the dismounting process is reversed.

[0103] In summary, the present application provides an LED display screen, through the setting of the rotating assembly and the clamping assembly, the bearing assembly can be placed and taken out in a transverse manner, the stability and convenience of the installation and dismounting of the bearing assembly are ensured, and the burden during operation is reduced.
