[0052] As shown in Figures 11-15As shown in the drawings, in an embodiment, the first connecting assembly 50 comprises a rotating assembly 5a and a clamping assembly 5b; the rotating assembly 5a can rotate the bearing assembly 20, so as 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.

[0053] As shown in the drawings, Figures 11-15 Optionally, the rotating assembly 5a comprises a driving part 5a1 and a support frame 5a2, the upper side of the support frame 5a2 is rotationally connected with the upper side of the main body, and the driving part 5a1 is used for driving the upper side of the support frame 5a2 to rotate around the rotationally connected 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.

[0054] As shown in the drawings, Figures 11-14 Optionally, the driving part 5a1 comprises a first rotating shaft 511, a first driving part 512 and a second driving part 513, which are arranged on the main body; the support frame 5a2 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 support frame 5a2 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.

[0055] As shown in the drawings, Figures 11-14 Optionally, the first driving part 512 comprises a first gear 12n and a first rack 12m, the first gear 12n is arranged on the first rotating shaft 511, and the first rack 12m is arranged on the support frame 5a2; 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.

[0056] As shown in the drawings, Figures 11-15 Optionally, the second driving part 513 comprises a second gear 13n, a third gear 13m and an inner gear ring 13x, the second gear 13n is arranged on the first rotating shaft 511, the gear ring is arranged on the support frame 5a2, the third gear 13m is located between the second gear 13n and the inner gear ring 13x, the second gear 13n, the third gear 13m and the inner gear ring 13x constitute a planetary gear set, and the first rotating shaft 511 drives the inner gear ring 13x to rotate through the second gear 13n and the third gear 13m, thereby driving the support frame 5a2 to rotate, reducing the driving force of the first rotating shaft 511 to drive the support frame 5a2 to rotate, and facilitating the installation and removal of the bearing assembly 20.

[0057] AsFigures 11-12 , Figure 15 As shown, optionally, the locking assembly 5b includes a slide rod 5b1, a push block 5b2, a fourth locking groove 5b3, and a fourth elastic member 5b4. The slide rod 5b1 is located on both sides of the support frame 5a2. The push block 5b2 is fixed on the side of the slide rod 5b1 away from the first rotating shaft 511. The fourth elastic member 5b4 can drive the slide rod 5b1 to move towards the side closer to the first rotating shaft 511. The fourth locking groove 5b3 is located on the main body 10. When the support frame 5a2 is rotated to a horizontal position, the slide rod 5b1 is fixed in the fourth locking groove 5b3 under the action of the fourth elastic member 5b4, so that the support frame 5a2 is fixed in the horizontal position. When it is necessary to release the slide bar 5b1, 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. Then the slide bar 5b1 will disengage from the fourth slot 5b3. The first rotating shaft 511 will then be able to rotate the support frame 5a2 to a vertical position under the action of the first rack 12m.

[0058] like Figure 13 As shown, optionally, the bearing assembly 20 is provided with a first stop 5c, and the first rotating shaft 511 is provided with a second stop 5d. When the first rack 12m disengages from the first gear 12n, the slide rod 5b1 is positioned directly opposite the fourth slot 5b3, that is, the slide rod 5b1 can be inserted into the fourth slot 5b3. When the first rack 12m disengages from the first gear 12n, the first stop 5c and the second stop 5d contact each other to block the rotation of the first rotating shaft 511, preventing the slide rod 5b1 from not corresponding to the fourth slot 5b3 after the first rack 12m disengages from the first gear 12n, thus preventing the support frame 5a2 from being fixed.

[0059] like Figures 11-12 , Figure 15 As shown, optionally, a third positioning element 5f and a positioning hole 5g are also included. The third positioning element 5f is installed on the side of the push block 5b2 away from the first rotating shaft 511, and the positioning hole 5g is located on the lower side of the main body. After the bearing assembly 20 pushes the push block 5b2 to move away from the first rotating shaft 511 to release the fixation, the bearing assembly 20 will continue to push the push block 5b2 to move away from the first rotating shaft 511 until the support frame 5a2 is rotated to a vertical position. Then, the bearing assembly 20 will push the push block 5b2 again to insert the third positioning element 5f into the positioning hole 5g. Under the action of the third positioning element 5f, the stability of the bearing assembly 20 after it is rotated to a vertical position can be ensured.

[0060] Optionally, the lower end of the third positioning element 5f is tapered to facilitate insertion into the positioning hole 5g for positioning.

[0061] like Figures 11-12 , Figures 14-15As shown, the first connecting assembly 50 also comprises a sliding mechanism 5h for mounting or dismounting the bearing assembly 20 and the support frame 5a2. The sliding mechanism 5h can ensure the stability of the mounting of the bearing assembly 20 and the support frame 5a2.

[0062] Optionally, the sliding mechanism 5h comprises a sliding groove 5h2 and a sliding protrusion 5h1. The sliding groove 5h2 is arranged on the support frame 5a2, and the sliding protrusion 5h1 is arranged on the bearing assembly 20. The bearing assembly 20 slides on the support frame 5a2 through the sliding groove 5h2 and the sliding protrusion 5h1, thereby ensuring the stability of the mounting.

[0063] Optionally, after the bearing assembly 20 is mounted on the support frame 5a2, the sliding groove 5h2 and the sliding protrusion 5h1 are arranged in an up-down manner. During the mounting or dismounting of the bearing assembly 20 through the sliding groove 5h2 and the sliding protrusion 5h1, the bearing assembly 20 is driven to rotate the first rotating shaft 511 through the first rack 12m and the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate through the planetary gear set, thereby ensuring the stable operation.

[0064] The implementation process of the rotation of the support frame 5a2 is as follows:

[0065] When the bearing assembly 20 is dismounted, the bearing assembly 20 moves upward along the sliding groove 5h2 through the sliding protrusion 5h1. After the bearing assembly 20 moves upward, the fourth elastic member 5b4 is first pulled to disengage from the positioning hole 5g. The bearing assembly 20 continues to move upward. The first rack 12m on the bearing assembly 20 drives the first rotating shaft 511 to rotate through the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate through the planetary gear set, until the support frame 5a2 is rotated to a horizontal placement state. The rotation of the support frame 5a2 also causes the bearing assembly 20 to rotate to a horizontal placement state. After the first rack 12m and the first gear 12n are disengaged, the slide rod 5b1 is placed in the fourth clamping groove 5b3 to fix the support frame 5a2. Then the bearing assembly 20 can be taken out.

[0066] When the bearing assembly 20 is mounted, the sliding protrusion 5h1 on the bearing assembly 20 is first placed in the sliding groove 5h2. Then the bearing assembly 20 is pushed to move along the sliding groove 5h2 until the bearing assembly 20 contacts and pushes the push block 5b2 to move. The slide rod 5b1 is disengaged from the fourth clamping groove 5b3. Then, the first rack 12m and the first gear 12n are engaged. The bearing assembly 20 drives the first rotating shaft 511 to rotate through the first rack 12m and the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate again through the planetary gear set, until the support frame 5a2 is rotated to a vertical placement. Finally, the bearing assembly 20 pushes the push block 5b2 to make the third positioning member 5f inserted into the positioning hole 5g, and the bearing assembly 20 is fixed.

[0083] Optionally, the limiting block 6a1 is provided with a clamping groove a11, and the limiting hole 6a2 is provided with a clamping block a22. When the clamping block a22 is placed in the clamping groove a11 by rotating the limiting block 6a1, the clamping block a22 limits the limiting block 6a1 and the limiting hole 6a2 from being separated through the clamping groove a11.

The first clamping groove 11a makes the limiting block 6a1 and the limiting hole 6a2 not easily separated; the second clamping groove 11b and the third clamping groove 11c can be displaced, which facilitates the movement of the clamping block a22, so that the limiting block 6a1 and the limiting hole 6a2 are installed or separated.

[0086] Preferably, the included angle of the first clamping groove 11a is 90 degrees.

When the first positioning member 6b1 is fixed to the second positioning member 6b2, the LED display assembly 30 and the bearing assembly 20 can be fixed.

[0088] Optionally, the first positioning member 6b1 is a strong magnet, which can be a ferrous boron magnet;

[0089] Optionally, the second positioning member 6b2 is a strong magnet, which can be a ferritic boron magnet.

[0090] As shown in Figures 1-5 Optionally, the second positioning member 6b2 can rotate, when the second positioning member 6b2 rotates to the opposite magnetic pole of the first positioning member 6b1, the first positioning member 6b1 is adsorbed and fixed with the second positioning member 6b2; when the second positioning member 6b2 rotates to the same magnetic pole of the first positioning member 6b1, the repulsion of the second positioning member 6b2 makes the first positioning member 6b1 move away from the second positioning member 6b2, and the first positioning member 6b1 can be separated from the second positioning member 6b2.

[0091] As shown in 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 unable to separate under the adsorption of strong magnet, and can reduce the rotation resistance when rotating, to ensure the stability of the second positioning member 6b2 when rotating.

[0092] Optionally, the bearing assembly 20 is provided with a second rotating shaft 6c, the 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 to drive the second positioning member 6b2 to rotate.

[0093] Optionally, the second rotating shaft 6c is provided with a driving wheel 6d, and the bearing assembly 20 is provided with a driving member 6e, which can drive the driving wheel 6d to rotate.

[0096] As shown in Figures 1-5As shown, the driving member 6e is towards the LED display assembly 30, and the LED display assembly 30 can push the driving member 6e to move when pushing the bearing assembly 20, thereby driving the driving wheel 6d to rotate, and making the second positioning member 6b2 rotate to the same magnetic pole as the first positioning member 6b1. The side of the driving member 6e away from the LED display assembly 30 is provided with a second elastic member 6f, which 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 make the driving wheel 6d rotate, and make the second positioning member 6b2 rotate to the opposite magnetic pole of the first positioning member 6b1. The LED display assembly 30 is provided with a clearance hole, and the first positioning member 6b1 is arranged in the clearance hole and can move axially relative to the clearance hole. When the LED display assembly 30 pushes the driving member 6e to move, the first positioning member 6b1 can give way to the second positioning member 6b2 to prevent jamming. The side of the first positioning member 6b1 away from the second positioning member 6b2 is provided with a third elastic member 6g, which gives the first positioning member 6b1 a force to move towards the second positioning member 6b2, so that the first positioning member 6b1 and the second positioning member 6b2 can keep in contact.

[0097] Optionally, the second rotating shaft 6c is provided with a delaying member (not shown in the figure), which can slow down the driving speed of the driving member 6e when the second elastic member 6f pushes the driving member 6e to move. After the second positioning member 6b2 rotates, the delaying member slows down the attraction between the second positioning member 6b2 and the first positioning member 6b1, so as to ensure sufficient operation time.

[0098] Preferably, the delaying member can be a liquid retarder arranged at the second rotating shaft 6c.

[0099] Preferably, the delaying member is a friction layer arranged on the second rotating shaft 6c, which slows down the rotation of the second rotating shaft 6c driven by the driving member 6e in the form of friction.

[0100] Optionally, the fixing mechanism 6b includes multiple groups and surrounds the side of the limiting mechanism 6a.

[0101] Preferably, the fixing mechanism 6b is 4 groups.

[0102] Optionally, the connecting head a1 is arranged at a position away from the LED display assembly 30 by the limiting block 6a1, the power supply port a2 is arranged in the limiting hole 6a2, and the power supply port a2 always has a force to move towards the LED display assembly 30.

[0103] As Figures 1-5As shown, when disassembly is needed, the LED display assembly 30 is adsorbed by the negative pressure suction cup, and then the LED display assembly 30 is pressed, the LED display assembly 30 is driven by the driving piece 6e to rotate the second positioning piece 6b2, the second positioning piece 6b2 is rotated to the same magnetic pole as the first positioning piece 6b1, the repulsion of the second positioning piece 6b2 enables the first positioning piece 6b1 to move away from the second positioning piece 6b2, and then the negative pressure suction cup is dragged to move the LED display assembly 30 away from the bearing assembly 20; at this time, the LED display assembly 30 is separated from other LED display assemblies 30 on the circumference, 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 is always located in the third clamping groove 11c to move, 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, and if no subsequent operation is taken, after the second positioning piece 6b2 is rotated to the opposite magnetic pole of the first positioning piece 6b1 under the action of the second elastic piece 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 is not flush with the adjacent LED display assembly 30, and then the LED display assembly 30 is rotated, so that the clamping block a22 moves along the first clamping groove 11a to the second clamping groove 11b, and finally the LED display assembly 30 is removed.

[0104] When installation is needed, the disassembly process is reversed.

[0105] In summary, the present application provides an LED display screen, by cooperation of the limiting mechanism and the fixing mechanism, after the fixing mechanism is separated, the LED display assembly will not be directly separated from the bearing assembly under the limiting of the limiting mechanism, and only after the limiting mechanism is removed, the LED display assembly and the bearing assembly can be separated, so that the problem of falling and damage of the LED display assembly due to not taking the LED display assembly when the fixing is removed is prevented.
