DETAILED DESCRIPTION

[0031] like Figure 1-4 As shown, a LED large screen splicing structure includes a fixing frame 3 for supporting the LED screen 1. Specifically, a U-shaped bracket 2 is fixedly installed on the back of the LED screen 1, and a guide rod 4 is fixedly connected to the bracket 2. The guide rod 4 passes through the fixing frame 3 and slides with it. In order to prevent the guide rod 4 from being out of contact with the fixing frame 3, a retaining ring is fixedly provided at one end of the guide rod 4 away from the LED screen 1, and the retaining ring is located on the side of the fixing frame 3 away from the LED screen 1;

[0032] In actual use, in order to facilitate the maintenance of the LED screen 1, a rotating shaft 6 is arranged at the center of the bracket 2. Specifically, a through hole is opened at the center of the bracket 2, and the rotating shaft 6 passes through the through hole. A spiral second limiting groove 601 is opened on the outer circumferential surface of the rotating shaft 6, and a second limiting block 18 matching the second limiting groove 601 is elastically arranged on the inner wall of the through hole. When the second limiting block 18 is in a pop-up state and inserted into the second limiting groove 601, the rotating shaft 6 can be rotated to drive the bracket 2 to move away from the fixing frame 3, thereby moving the LED screen 1 out, which is convenient for the staff to inspect it. A spiral first limiting groove 201 is opened on the inner wall of the through hole, and a first limiting block 16 matching the first limiting groove 201 is elastically connected to the rotating shaft 6. When the first limiting block 16 is in a pop-up state and inserted into the first limiting groove 201, the rotation of the rotating shaft 6 can drive the bracket 2 to gradually approach the fixing frame 3, thereby completing the installation of the LED screen 1.

[0033] Furthermore, the rotating shaft 6 is provided with a traction component that cooperates with the first limit block 16, and the bracket 2 is provided with a clamping component that cooperates with the second limit block 18. In order to drive the rotating shaft 6 to rotate, a coil spring 8 is sleeved on the outer side of the rotating shaft 6, and the two ends of the coil spring 8 are respectively connected to the rotating shaft 6 and the fixing frame 3. In the initial state, one end of the second limit block 18 is located in the second limit groove 601. At this time, the positive rotation of the rotating shaft 6 can drive the bracket 2 to gradually move away from the fixing frame 3. When the second limit block 18 slides to the end of the second limit groove 601, the second limit block 1 8 is squeezed into the bracket 2, and the second limit block 18 can be locked by the snap-on assembly. When the LED screen 1 needs to be reinstalled, the shaft 6 can be rotated in the opposite direction to compress the coil spring 8. During this process, the centrifugal force generated by the shaft 6 enables the traction assembly to pull the first limit block 16, thereby making the first limit block 16 in a pop-up state and finally cooperate with the first limit groove 201. Thereafter, when the shaft 6 rotates forward under the action of the coil spring 8, the LED screen 1 can be reinstalled through the cooperation of the first limit block 16 and the first limit groove 201.

[0034] Specifically, one end of the second limiting groove 601 is configured as an inclined guide surface 602 , so that the second limiting block 18 can move out of the second limiting groove 601 .

[0035] As Figure 3-10 As shown, the above-mentioned clamping assembly includes a clamping block 19 elastically connected to the bracket 2, and a clamping slot matching with the clamping block 19 is opened on the side of the second limit block 18. When the clamping block 19 pops out and is inserted into the inside of the clamping slot, the second limit block 18 can be locked;

[0036] Furthermore, a magnetic plate 301 is fixedly embedded on one side surface of the fixing frame 3 close to the bracket 2, and the above-mentioned block 19 is made of iron. When the bracket 2 gradually moves away from the fixing frame 3, the magnetic plate 301 and the block 19 gradually move away from each other, so that the block 19 can be in a pop-up state.

[0037] The traction assembly includes a pressure block 17 disposed below the first limit block 16. The pressure block 17 is configured as a U-shape as a whole. A limit spring is fixedly disposed between the pressure block 17 and the first limit block 16.

[0038] Furthermore, a shaft sleeve 11 is sleeved on one end of the rotating shaft 6 passing through the fixing frame 3, and the shaft sleeve 11 is connected to the rotating shaft 6 via a one-way bearing. A counterweight 12 is slidably arranged on the shaft sleeve 11. When the rotating shaft 6 drives the shaft sleeve 11 to rotate, the counterweight 12 slides outwards under the influence of centrifugal force. A pull rope 10 is fixedly arranged between the counterweight 12 and the pressing block 17. When the counterweight 12 slides outwards, the pull rope 10 can be tightened, so that the pressing block 17 is driven by the pull rope 10 to gradually approach the first limit block 16, thereby squeezing out the first limit block 16.

[0039] Furthermore, a baffle 22 is elastically provided on the rotating shaft 6, and the baffle 22 is set to be U-shaped. An iron block 20 is provided above the baffle 22, and a connecting rod is fixedly provided between the iron block 20 and the baffle 22. Blocks 23 are elastically provided on both side surfaces inside the baffle 22, and an end of the block 23 extending to the outside of the baffle 22 is provided with an inclined surface 2301, and a protrusion 21 is fixedly provided on the outer side of the above-mentioned pull rope 10. In the process of the pull rope 10 pulling the pressure block 17 to move upward, the protrusion 21 will contact the inclined surface 2301 on the block 23 and squeeze the block 23 into the baffle 22. When the protrusion 21 passes over the block 23, the block 23 can pop out again and limit the protrusion 21, thereby preventing the pull rope 10 from resetting. A magnetic ring 5 is sleeved on the outer side of the rotating shaft 6, and the magnetic ring 5 is fixedly connected to the bracket 2.

[0040] In order to position the rotating shaft 6, a plurality of positioning grooves 9 are evenly provided on the outer circumferential surface of the rotating shaft 6, and a positioning block 13 cooperating with the positioning groove 9 is slidably provided on the fixed frame 3, and a second inclined surface 1301 is provided at the bottom end of the positioning block 13, so that the rotating shaft 6 can only rotate in one direction relative to the positioning block 13, and a sliding block 14 is fixedly provided at the top end of the positioning block 13, and the sliding block 14 is made of iron, and an electromagnet 15 cooperating with the sliding block 14 is fixedly installed on the fixed frame 3.

[0041] When the rotating shaft 6 rotates in the reverse direction, in order to prevent the first limiting block 16 from interfering with the first limiting groove 201 , a third inclined surface 1601 is provided at one end of the first limiting block 16 away from the pressing block 17 .

[0042] When the LED screen 1 needs to be repaired, the electromagnet 15 can be controlled to be energized, and the suction force of the electromagnet 15 on the slider 14 can drive the positioning block 13 to move upward, so that one end of the positioning block 13 is moved out of the positioning groove 9. At this time, the rotating shaft 6 can be driven to rotate forward under the action of the coil spring 8, and the bracket 2 can be driven to move away from the fixing frame 3 through the cooperation of the second limiting block 18 and the second limiting groove 601, so as to move out of the LED screen 1, which is convenient for the staff to repair it. Since the rotating shaft 6 and the sleeve 11 are connected by a one-way bearing The second limit block 18 is connected to the bracket 2 so that the shaft 6 does not drive the shaft sleeve 11 to rotate during the process, so that the first limit block 16 is stored in the shaft 6 during the process. When the second limit block 18 slides to the end of the second limit groove 601, the second limit block 18 is squeezed by the guide surface 602, so that the second limit block 18 moves in the direction away from the shaft 6. When the clamping block 19 is aligned with the clamping groove, the clamping block 19 pops out and is inserted into the clamping groove, thereby locking the second limit block 18 with the bracket 2, thereby preventing the second limit block 18 from matching with the shaft 6.

[0043] When the maintenance is completed, the staff can rotate the coil spring 8 in the opposite direction to compress it. During this process, the electromagnet 15 can be de-energized, so that the positioning block 13 cooperates with the positioning groove 9, so that the rotating shaft 6 can only rotate in one direction relative to the positioning block 13. This structure allows the staff to rotate the rotating shaft 6 more stably. During this process, the third inclined surface 1601 on the first limit block 16 will contact and squeeze the side edge of the first limit groove 201, thereby avoiding interference between the first limit block 16 and the rotating shaft 6. During the reverse rotation of the rotating shaft 6, the shaft sleeve 11 can be driven to rotate through the rotating shaft 6. At this time, the counterweight block 12 can be prompted to move outward under the action of centrifugal force. As the counterweight block 12 slides outward, the pull rope 10 can be used to pull the pressure block 17, thereby driving the pressure block. 17 moves upward and squeezes the first limit block 16 through the limit spring, so that the first limit block 16 has a tendency to pop out. In the process of the pull rope 10 pulling the pressure block 17, the protrusion 21 will squeeze the stopper 23. When the protrusion 21 passes over the stopper 23, the stopper 23 can limit the protrusion 21, thereby preventing the pull rope 10 from resetting, so that the pressure block 17 can be stably pulled by the pull rope 10. Later, when the electromagnet 15 is energized to make one end of the positioning block 13 withdrawn from the positioning groove 9, the force of the coil spring 8 can drive the rotating shaft 6 to rotate forward again. When the first limit block 16 pops out and is inserted into the first limit groove 201, the cooperation between the two can drive the bracket 2 to gradually approach the fixing frame 3, thereby retracting the LED screen 1, which is conducive to the completion of the installation of the LED screen 1.

[0044] When the bracket 2 moves to the fixing frame 3 and fits therewith, it stops moving. At this time, the magnetic ring 5 is located on the outside of the iron block 20. The suction force between the two can drive the iron block 20 and the baffle 22 to move outward, thereby causing the baffle 23 to be offset from the protrusion 21, which is conducive to loosening the pull rope 10. When the pull rope 10 is loosened, the pressure block 17 can drive the first limit block 16 to gradually reset, thereby causing the first limit block 16 to gradually move out of the first limit groove 201. In addition, the suction force between the magnetic plate 301 and the card block 19 can drive the card block 19 to move outward and separate from the card groove, thereby allowing the second limit block 18 to reset and cooperate with the second limit groove 601. After that, the electromagnet 15 is de-energized to complete the installation of the LED screen 1. The next time the electromagnet 15 is maintained, the LED screen 1 can be moved out by simply energizing the electromagnet 15.

[0045] To summarize, this device, through the arrangement of the first limit block 16 and the second limit block 18 and other structures, enables the rotating shaft 6 to drive the bracket 2 to slide in different directions during the process of rotating in one direction, thereby facilitating the removal of the LED screen 1 or the installation of the LED screen 1. The driving of the rotating shaft 6 can be completed by energizing or de-energizing the electromagnet 15, making the overall operation more convenient and the overall structure relatively light and stable. In addition, the structure in this scheme is convenient for the staff to exert force during operation, especially for high-altitude operations, the staff can operate this device more stably.
