DETAILED DESCRIPTION

[0022] The technical scheme in the utility model will be further described below in combination with the drawings and embodiments.

[0023] As Figs. 1-3 shown, the embodiment of the utility model discloses a wind pressure resisting reinforced type splicing mechanism of court screen box, which comprises:

[0024] The adjacent screen boxes 1 are locked through bolts, and the screen box 1 is installed on the corresponding frame body, which is the prior art.

[0025] The splicing mechanism 3 is used for mounting the LED screen 2 on the screen box 1, and the splicing mechanism 3 comprises a connecting sleeve 6 mounted on the inner wall of the screen box 1, and the inner wall of the screen box 1 is welded with a supporting block 4, and the connecting sleeve 6 is welded on the supporting block 4, and the connecting sleeve 6 is made of stainless steel, so as to ensure the stability between the connecting sleeve 6 and the supporting block 4.

[0026] The connecting column 7 is fixed on the LED screen 2, and the connecting column 7 is connected with the connecting sleeve 6 through a magnetic attraction mechanism, the first magnet 9 is fixed in the connecting sleeve 6, the second magnet 10 is fixed on the bottom of the connecting column 7, the opposite faces of the first magnet 9 and the second magnet 10 have opposite magnetic poles, and the first magnet 9 and the second magnet 10 are used for pre-mounting the connecting column 7, that is, pre-mounting the LED screen 2.

[0027] The inner wall of the screen box 1 is fixed with a fixed box 5, the fixed box 5 is fixed with an electromagnet 13 connected with the LED screen 2, the fixed box 5 is slidably provided with a magnetic block 14 used in cooperation with the electromagnet 13, and the opposite face of the magnetic block 14 and the electromagnet 13 has the same magnetic pole; wherein the electromagnet 13 is connected with a module power supply in the screen box 1, and can be connected through a wire.

[0028] The magnetic block 14 is fixed with a locking pin 8, wherein the magnetic block 14 is fixed with a spring 11, the spring 11 is fixedly connected with the inner wall of the fixed box 5, and is used for resetting the magnetic block 14 and the locking pin 8; wherein the repulsion between the magnetic block 14 and the electromagnet 13 is greater than the elastic force of the spring 11, that is, the magnetic block 14 can be driven to move. The fixed box 5 is provided with a sliding groove, and the locking pin 8 is slidably connected in the sliding groove; the connecting column 7 is provided with a locking groove 12, and the locking pin 8 is slidably connected in the locking groove 12, so as to lock the connecting column 7 in the connecting sleeve 6.

[0029] Wherein, the connecting sleeve 6 is provided with a through hole, the through hole is opposite to the locking groove 12, and the initial state of the locking pin 8 is located in the through hole.

[0030] Pre-installation stage

[0031] Connecting sleeve and supporting block installation: the inner wall of the screen box 1 is pre-welded with the supporting block 4, and the connecting sleeve 6 is firmly fixed on the supporting block 4 through welding. The connecting sleeve 6 is made of stainless steel, which ensures the structural strength and stability.

[0032] Magnetic attraction pre-positioning: the connecting column 7 is mounted on the back of the LED screen 2, the bottom of the connecting column 7 is embedded with the second magnet 10, and the connecting sleeve 6 is internally fixed with the first magnet 9. Since the opposite faces of the first magnet 9 and the second magnet 10 have opposite magnetic poles, when the LED screen 2 approaches the screen box 1, the magnetic attraction makes the connecting column 7 automatically adsorb into the connecting sleeve 6, so as to realize the rapid pre-positioning of the LED screen 2.

[0033] Locking stage

[0034] The electromagnet and the magnetic block repulsion drive: the fixed box 5 is fixed on the inner wall of the screen box 1, the electromagnet 13 is installed in the fixed box 5, and the module power supply of the screen box 1 is connected through the wire. The magnetic block 14 is slidably installed in the fixed box 5, and the opposite poles of the magnetic block 14 and the electromagnet 13 are the same. After being electrified, the electromagnet 13 generates a magnetic field, and forms repulsion between the magnetic block 14, drives the magnetic block 14 to move to the connecting column 7.

[0035] The lock pin sliding locking: the lock pin 8 is fixed on the magnetic block 14 and connected with the inner wall of the fixed box 5 through the spring 11. When the electromagnet 13 is electrified, the repulsion is greater than the elastic force of the spring 11, the magnetic block 14 overcomes the spring resistance and slides, drives the lock pin 8 to move along the sliding groove of the fixed box 5. At this time, the lock pin 8 is inserted into the lock slot 12 of the connecting column 7 from the through hole of the connecting sleeve 6, and the locking of the connecting column 7 is completed. Since the connecting column 7 is located in the connecting sleeve 6, the up and down and horizontal direction of the connecting column 7 is limited, so that it is not easy to move, and the stability is further ensured.

[0036] As described above, compared with the prior art, the installation of the LED screen 2 is more stable, and the wind pressure effect is better. Therefore, the stability during use can be ensured.

[0037] Reset and disassembly stage

[0038] Power-off release: when the LED screen 2 needs to be disassembled, the power supply of the electromagnet 13 is disconnected, and the repulsion disappears. The elastic force of the spring 11 resets the magnetic block 14, drives the lock pin 8 to exit the lock slot 12, and the connecting column 7 is unlocked.

[0039] Magnetic attraction auxiliary disassembly: after the connection is disconnected, the magnetic force of the first magnet 9 and the second magnet 10 can still assist the stable removal of the LED screen 2, avoiding mechanical jamming.

[0040] Efficient installation: magnetic attraction pre-positioning realizes rapid alignment, electromagnet driving realizes one-key locking, and installation time is significantly shortened.

[0041] High stability: stainless steel connecting sleeve and magnetic- mechanical double locking mechanism ensure the reliability of the LED screen in complex environment.

[0042] Modular design: each component is independently packaged, which is convenient for maintenance and upgrading, and reduces maintenance cost.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application. The technical solutions should be covered in the scope of the claims of the present application.
