Detailed implementation mode
[0021] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with specific embodiments.
[0022] As Figure 1 , Figure 2 and Figure 3 shown, a magnetic attraction type background frame includes a left frame 1 and a right frame 2. The left frame 1 and the right frame 2 include round tubes 3. The left frame 1 and the right frame 2 are assembled and spliced through a plurality of round tubes 3. A magnetic attraction structure 4 is arranged inside adjacent round tubes 3. The magnetic attraction structure 4 is used for adsorbing and assembling between the left frame 1 and the right frame 2;
[0023] The magnetic attraction structure 4 includes a first straight magnetic attraction part 5 and a second straight magnetic attraction part 6 inserted inside the round tube 3. A magnet 8 is arranged inside the connection part of the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6. A sleeve 7 is sleeved inside the magnet 8. An internal hexagonal flat head screw 11 penetrates through the inside of the sleeve 7. The internal hexagonal flat head screw 11 penetrates through the inside of the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6, and a locknut 9 is connected to one end of the internal hexagonal flat head screw 11;
[0024] Bullet heads 10 are clamped at one ends of the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6. A clamping post 12 is fixedly installed on the outside of the bullet head 10. Clamping holes 13 corresponding to the clamping post 12 are formed on the outside of the round tube 3, the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6.
[0025] In this implementation mode, during the process of assembling the left frame 1 and the right frame 2, the magnet 8 inside the magnetic attraction structure 4 is sleeved outside the sleeve 7. The internal hexagonal flat head screw 11 sequentially penetrates through the first straight magnetic attraction part 5, the sleeve 7 and the second straight magnetic attraction part 6, and then is tightened through the locknut 9. The magnet 8 on the straight magnetic attraction part and the sleeve 7 is limited. The two ends of the straight magnetic attraction part are respectively inserted into the bullet head 10. After combination, the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6 are inserted into the round tube 3. The clamping post 12 on the bullet head 10 penetrates through the first straight magnetic attraction part 5 and the second straight magnetic attraction part 6 and the clamping hole 13 of the round tube 3, completing the limitation of the magnetic attraction structure 4 and the round tube 3 and completing the installation of the left frame 1 and the right frame 2;
[0026] When the left frame 1 and the right frame 2 need to change directions, change the direction angle of the connection between the left frame 1 and the right frame 2. The left frame 1 and the right frame 2 can be flexibly changed and adsorbed by the magnetic structure 4 in the adjacent circular tube 3 to achieve the frame support required for displaying backgrounds of different sizes.
[0027] As an implementation method, as Figure 2 and Figure 3 shown, the connection parts of the straight magnetic part one 5 and the straight magnetic part two 6 are both set as stepped openings, and arc pieces 15 are arranged in the stepped openings.
[0028] In this implementation method, the straight magnetic part one 5 and the straight magnetic part two 6 are combined through the stepped opening. Under the combination of the stepped opening and the arc piece 15, the arc piece 15 contacts the inner wall of the stepped opening, so that the straight magnetic part one 5 and the straight magnetic part two 6 are mutually clamped, improving the clamping speed and the connection accuracy between the straight magnetic parts.
[0029] As an implementation method, as Figure 2 and Figure 3 shown, the card holes 13 are equidistantly distributed on the outsides of the straight magnetic part one 5 and the straight magnetic part two 6, and anti-slip strips 14 are distributed around the outsides of the straight magnetic part one 5 and the straight magnetic part two 6.
[0030] In this implementation method, when the straight magnetic part one 5 and the straight magnetic part two 6 are inserted into the circular tube 3 after combination, the anti-slip strips 14 on the outsides of the straight magnetic part one 5 and the straight magnetic part two 6 are used to rub against the inner wall of the circular tube 3 during the insertion process, improving the connection strength and stability between the magnetic structure 4 and the circular tube 3, and preventing the magnetic structure 4 from moving or sliding when subjected to external forces;
[0031] At the same time, the clamping posts 12 on the bullet heads 10 penetrate through the straight magnetic part one 5 and the straight magnetic part two 6 and the card holes 13 of the circular tube 3 to complete the limit of the magnetic structure 4 and the circular tube 3.
[0032] As an implementation method, as Figure 3 shown, connection holes for accommodating the through penetration of the socket head cap screws 11 are opened inside the straight magnetic part one 5, the straight magnetic part two 6 and the sleeve 7, and the inner diameter of the sleeve 7 is larger than the outer diameter of the socket head cap screws 11.
[0033] In this implementation method, the socket head cap screws 11 penetrate through the straight magnetic part one 5, the sleeve 7 and the straight magnetic part two 6 in sequence, and then are tightened through the lock nuts 9 to limit the magnets 8 on the straight magnetic parts and the sleeve 7. At the same time, the inner diameter of the sleeve 7 is larger than the outer diameter of the socket head cap screws 11, and the magnets 8 and the sleeve 7 can rotate outside the socket head cap screws 11.
[0034] As an implementation method, as Figure 3As shown, the magnet 8 is a hollow ring, and there is a 0.5 mm gap between the straight magnetic attracting member 1 and the straight magnetic attracting member 2 and the magnet 8.
[0035] In this embodiment, a 0.5 mm gap exists around the cavity formed by the magnet 8 and the straight magnetic attracting member 1 and the straight magnetic attracting member 2, ensuring that the magnet 8 embedded in the sleeve 7 can rotate freely both in the cavity and on the socket head cap screw 11, and can also be adsorbed when changing the combination angle between the left frame 1 and the right frame 2.
[0036] As an embodiment, as Figure 2 and Figure 3 shown, the warhead 10 is arranged in a V-shaped structure, and the warhead 10 is mirror-symmetrically arranged with the center of the magnet 8 as the reference.
[0037] In this embodiment, when the straight magnetic attracting member 1 and the straight magnetic attracting member 2 are inserted into the round tube 3, the two ends are respectively inserted into the warhead 10. The clamping post 12 on the warhead 10 penetrates through the straight magnetic attracting member 1 and the straight magnetic attracting member 2 and the clamping hole 13 of the round tube 3 to complete the limit of the magnetic attracting structure 4 and the round tube 3. When the V-shaped warhead 10 is squeezed by the clamping post 12, the magnetic attracting structure 4 is separated from the round tube 3.
[0038] Working principle: During use, in the process of assembling the left frame 1 and the right frame 2, the magnet 8 in the magnetic attracting structure 4 is sleeved outside the sleeve 7. The socket head cap screw 11 sequentially penetrates through the straight magnetic attracting member 1, the sleeve 7 and the straight magnetic attracting member 2, and then is tightened through the lock nut 9. The straight magnetic attracting member is limited by the magnet 8 on the sleeve 7. The inner diameter of the inner sleeve 7 is larger than the outer diameter of the socket head cap screw 11, and a 0.5 mm gap exists around the cavity formed by the magnet 8 and the straight magnetic attracting member 1 and the straight magnetic attracting member 2, ensuring that the magnet 8 embedded in the sleeve 7 can rotate freely both in the cavity and on the socket head cap screw 11;
[0039] The two ends of the straight magnetic attracting member are respectively inserted into the warhead 10. After combination, the straight magnetic attracting member 1 and the straight magnetic attracting member 2 are inserted into the round tube 3. During the insertion process, the external anti-slip strips 14 of the straight magnetic attracting member 1 and the straight magnetic attracting member 2 are used to rub against the inner wall of the round tube 3 to improve the connection strength and stability between the magnetic attracting structure 4 and the round tube 3, preventing the magnetic attracting structure 4 from moving or sliding when subjected to external forces;
[0040] After insertion, the clamping post 12 on the warhead 10 penetrates through the straight magnetic attracting member 1 and the straight magnetic attracting member 2 and the clamping hole 13 of the round tube 3 to complete the limit of the magnetic attracting structure 4 and the round tube 3, and complete the installation of the left frame 1 and the right frame 2. When the left frame 1 and the right frame 2 need to change directions, change the direction angle of the connection between the left frame 1 and the right frame 2, and use the magnetic attracting structures 4 in the adjacent round tubes 3 to adsorb to achieve the frame support required for displaying backgrounds of different sizes.
