[0028] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 4 to 6As shown, one embodiment of this utility model provides a splicing component 13, including a lock body 51 and a lock base 14 disposed opposite to each other. The lock base 14 includes a first fixing block 30 and a locking block 15. The first fixing block 30 is used to connect to the first display unit 1 of the LED display screen. The first fixing block 30 has a mounting surface 31 on the side facing the lock body 51. The locking block 15 is movably connected to the mounting surface 31. The locking block 15 has a locking hook 18 on the side facing away from the first fixing block 30. The locking hook 18 has a locking groove 19. The locking hook 18 has a main abutment surface on the side facing the lock body 51. The included angle between the main abutment surface and the mounting surface 31 is adjustable.

[0030] The lock body 51 includes a second fixing block 61, a support block 10, and a latch 52. The second fixing block 61 is used to connect to the second display unit 4 of the LED display screen. The support block 10 is connected to the second fixing block 61. The support block 10 has a second abutting surface 86 on the side facing the first fixing block 30. The latch 52 can be locked in the lock groove 19 so that the second abutting surface 86 abuts against the main abutting surface.

[0031] Specifically, the angle between the main abutment surface on the lock hook 18 and the mounting surface 31 on the first fixing block 30 is adjustable. When the lock 52 is locked to the lock groove 19, the second abutment surface 86 of the lock body 51 abuts against the first abutment surface 20, causing the angle between the second abutment surface 86 and the mounting surface 31 to change accordingly. Since the bearing block 10 with the second abutment surface 86 is connected to the second display unit 4, and the first fixing block 30 with the mounting surface 31 is connected to the first display unit 1, the angle between the first display unit 1 and the second display unit 4 can be adjusted, thereby adjusting the curvature of the LED display and improving the applicability of the LED display.

[0032] In one embodiment, the mounting surface 31 is provided with a sliding groove 34, the locking block 15 is slidably connected to the sliding groove 34, and a plurality of locking hooks 18 are provided. The plurality of locking hooks 18 are arranged at intervals along the sliding direction of the locking block 15. Each locking hook 18 has a first abutting surface 20 on the side facing the second abutting surface 86, and the included angle between each first abutting surface 20 and the mounting surface 31 is different.

[0033] Of all the hooks 18, the first abutment surface 20 of the hook 18 that is directly opposite the second abutment surface 86 serves as the main abutment surface.

[0034] Specifically, the mounting surface 31 is located on the side of the first fixing block 30 facing the lock body 51. The mounting surface 31 is provided with a sliding groove 34 extending in the vertical direction. The lock block 15 is slidably connected in the sliding groove 34.

The included angle between each first abutment surface 20 and the mounting surface 31 is different. When it is necessary to adjust the curvature of the LED display screen, the locking block 15 is slid up and down so that the first abutment surface 20 of the required angle is aligned with the second abutment surface 86 as the main abutment surface. Then, the latch 52 of the lock body 51 is placed in the lock groove 19. The angle between the main abutment surface and the mounting surface 31 is changed by sliding up and down, which is simple in structure and easy to design.

[0036] In one embodiment, the first abutting surface 20 is provided with a first positioning post 22, and the second abutting surface 86 is provided with a first positioning hole 11, wherein the first positioning post 22 and the first positioning hole 11 are inserted into each other.

[0038] Furthermore, the diameters of the first connecting hole 25 and the second connecting hole 26 are both larger than the diameter of the first pin 23, allowing the first positioning post 22 to move axially within the first insertion hole 21 without disengaging from it. One end of the first positioning post 22 facing the first insertion hole 21 is connected to the bottom wall of the hole via a spring 24. The spring 24 drives the first positioning post 22 to move towards the second abutment surface 86, assisting in its insertion into the first positioning hole 11 on the second abutment surface 86. The engagement of the first positioning post 22 with the first positioning hole 11 helps the first abutment surface 20 and the second abutment surface 86 to fit tightly together.

[0039] In one embodiment, the lock base 14 further includes a first locking mechanism for locking the lock block 15 in the slide groove 34. The first locking mechanism is used to lock the lock block 15 in the slide groove 34 to prevent the lock block 15 from sliding freely in the slide groove 34.

[0040] In one embodiment, the locking block 15 is provided with a first slot 29 on the side facing the first fixing block 30.

By inserting a third pin 42 through the third connecting hole 38, the fourth connecting hole 39 and the fifth connecting hole 41, the second pin 40, the transition block 37 and the first connecting arm 36 are connected together. The other end of the second pin 40 is provided with a sixth connecting hole 43. The first locking member 44 is provided with a seventh connecting hole 45. The connecting arm is provided with an eighth connecting hole 47. By inserting a fourth pin 48 through the sixth connecting hole 43, the seventh connecting hole 45 and the eighth connecting hole 47, the first locking member 44 is rotatably mounted on the connecting arm.

[0043] The first driving member 49 includes a first wrench 50 connected to the first locking member 44. The locking member has an abutment angle 46 on the side facing the locking block 15. The abutment angle 46 protrudes from the locking member on the side facing the locking block 15. When it is necessary to lock the locking block 15, the first wrench 50 is pulled in the direction of the locking block 15. The first wrench 50 drives the first locking member 44 to rotate, so that the first locking member 44 rotates to the first locking position, so that the abutment angle 46 is engaged in the first slot 29 on the locking block 15, thereby locking the locking block 15 in the slide groove 34. When it is necessary to unlock the locking block 15, the first wrench 50 is pulled in the opposite direction. The first wrench 50 drives the first locking member 44 to rotate in the opposite direction, so that the first locking member 44 rotates to the first unlocking position, so that the abutment angle 46 disengages from the first slot 29, thereby unlocking the locking block 15.

[0044] In one embodiment, the lock body 51 further includes a second locking mechanism for locking the latch 52 in the lock groove 19.

[0045] The second fixing block 61 has a second slot 62 on the side opposite to the first fixing block 30.

[0046] The second locking mechanism includes a lock housing 58, a second locking member 68, and a second driving member. The lock housing 58 is rotatably connected to the second fixing block 61. The end of the latch 52 away from the first fixing block 30 is rotatably connected to the lock housing 58. The second locking member 68 is rotatably connected to the lock housing 58. The second locking member 68 has a second locking position that engages with the second slot 62 and a second unlocking position that disengages from the second slot 62. The second driving member is connected to the lock housing 58, and the second locking member 68 is connected to the second driving member. The second driving member is used to drive the second locking member 68 to move between the second locking position and the second unlocking position.

[0047] Specifically, the latch 52 includes a second wrench 53 and a tensioning post 55 for locking with the lock groove 19. The end of the tensioning post 55 away from the lock seat 14 is threaded. The threaded end of the tensioning post 55 passes through the second wrench 53 and is fixed to the second wrench 53 by a washer 57 and a nut 56. The first rotating shaft 54 ​​on the second wrench 53 is rotatably inserted into the first rotating shaft hole 59 of the lock housing 58 so that the second wrench 53 and the tensioning post 55 can rotate relative to the lock housing 58.

[0048] The lock housing 58 has a second pivot hole 60 on the front side of the first pivot hole 59, and the second fixing block 61 has a third pivot hole 65. By inserting a second pivot 66 through the second pivot hole 60 and the third pivot hole 65, the front end of the lock housing 58 can be rotated and assembled onto the second fixing block 61.

[0049] The second locking member 68 includes a snap-fit ​​part 71, a rotating part 69 and a driving part 73 connected in sequence. The rotating part 69 is provided with a fourth pivot hole 70, and the second connecting arm 74 of the lock housing 58 is provided with a fifth pivot hole 85. By passing a third pivot 75 through the fourth pivot hole 70 and the fifth pivot hole 85, the rotating part 69 is rotatably assembled onto the lock housing 58.

[0050] The second driving component includes a first torsion spring 77 and a fixed post 76. The rotating part 69 is provided with a driving hole 72. The fourth rotating shaft hole 70 is provided through the driving hole 72. The first torsion spring 77 includes a connected main body part 78, a fixed end 80 and a driving end 79. The main body part 78 is installed in the driving hole 72 and is sleeved on the third rotating shaft 75.

[0051] The second connecting arm 74 of the lock housing 58 is provided with a sixth pivot hole 81 on the rear side of the fifth pivot hole 85. The fixing post 76 passes through the sixth pivot hole 81. The driving end 79 of the first torsion spring 77 is connected to the upper side of the fixing post 76, and the fixing end 80 is connected to the edge of the hole near the second fixing block 61 of the driving hole 72. The first torsion spring 77 can drive the rotating part 69 to rotate, so that the second locking member 68 rotates to the second locking position, and at the same time, the locking part 71 swings towards the second slot 62, so that the locking part 71 engages with the second slot 62 on the first fixing block 30.

[0052] When it is necessary to unlock the second locking member 68, manually press the drive part 73 to make the second locking member 68 rotate in the opposite direction to the second unlock position, so that the locking part 71 disengages from the second slot 62 on the second fixing block 61. At this time, by pulling the second wrench 53 downward, the tensioning column 55 disengages from the lock slot 19, so that the lock body 51 and the lock seat 14 are unlocked.

[0053] In addition, a second torsion spring 67 is also fitted on the first rotating shaft 54. One end of the second torsion spring 67 is connected to the first rotating shaft 54, and the other end of the second torsion spring 67 is connected to the lock housing 58. The second torsion spring 67 is used to drive the first rotating shaft 54 ​​to rotate, so that the locking pin swings away from the lock groove 19 to assist the tensioning pin 55 in disengaging from the lock groove 19.

[0054] When it is necessary to lock the lock seat 14 and the lock body 51, press the drive part 73 of the second locking member 68 to disengage the locking part 71 from the second slot 62. Then, lift the second wrench 53 to lock the tensioning post 55 in the lock groove 19. Then, turn the handle part 82 of the lock shell 58 toward the direction close to the first fixing block 30. Finally, release the drive part 73. Relying on the elastic force of the first torsion spring 77, the first torsion spring 77 drives the second locking member 68 to rotate, so that the locking part 71 abuts against the second slot 62. At this time, the pull force between the lock shell 58 and the second fixing block 61 and the pull force between the tensioning post 55 and the lock groove 19 will lock the latch 52 in the lock groove 19.

[0055] When unlocking is required, press the drive unit 73 again to unlock the locking part 71 from the slot. Then, turn the handle part 82 of the lock case 58 away from the first fixing block 30 to release the tension between the lock case 58 and the second fixing block 61. After that, by pressing down the second wrench 53, the tensioning column 55 is swung away from the lock groove 19, so that the tensioning column 55 is disengaged from the lock groove 19, thus unlocking.

[0056] According to the splicing component 13 of this utility model embodiment, compared with the prior art, the included angle between the main abutment surface on the lock hook 18 and the mounting surface 31 on the first fixing block 30 is adjustable. When the lock buckle 52 and the lock groove 19 are locked, the second abutment surface 86 of the lock body 51 abuts against the first abutment surface 20, so that the included angle between the second abutment surface 86 and the mounting surface 31 also changes. Since the bearing block 10 with the second abutment surface 86 is connected to the second display unit 4, and the first fixing block 30 with the mounting surface 31 is connected to the first display unit 1, the included angle between the first display unit 1 and the second display unit 4 can be adjusted, thereby adjusting the curvature of the LED display and improving the applicability of the LED display.

[0057] In addition, such as Figures 1 to 3 As shown, an embodiment of the present invention provides an LED display screen, including a first display screen unit 1, a second display screen unit 4 and the splicing component 13 described above.

[0063] Specifically, the second sliding part 17 is provided with a ball hole 27, and a ball 28 is installed in the ball hole 27. When the first abutment surface 20 of the locking block 15 at the required angle slides to the position facing the second abutment surface 86, the ball 28 enters the arc groove 9 and generates a certain vibration to indicate that the locking block 15 moves into place, so as to ensure that the first abutment surface 20 and the second abutment surface 86 are facing each other.

[0064] The working principle of the LED display screen of this utility model embodiment is as follows:

[0065] When the curvature of the LED display needs to be adjusted, first slide the locking block 15 up and down so that the first abutting surface 20 of the required angle is directly opposite the second abutting surface 86. Then, pull the first wrench 50 toward the side where the locking block 15 is located. The first wrench 50 drives the first locking member 44 to rotate, so that the first locking member 44 rotates to the first locking position, so that the abutting angle 46 is engaged in the first slot 29 on the locking block 15, thereby locking the locking block 15 in the slide groove 34.

[0066] Then, lock the lock base 14 and lock body 51: When it is necessary to lock the lock base 14 and lock body 51, press the drive part 73 of the second locking member 68 to disengage the locking part 71 from the second slot 62. Then, lift the second wrench 53 to lock the tensioning column 55 in the lock groove 19. Then, turn the handle part 82 of the lock case 58 toward the direction close to the first fixing block 30. Finally, release the drive part 73. Relying on the elastic force of the first torsion spring 77, the first torsion spring 77 drives the second locking member 68 to rotate, so that the locking part 71 abuts against the second slot 62. At this time, the latch 52 is locked by the tension between the lock case 58 and the second fixing block 61 and the tension between the tensioning column 55 and the lock groove 19, so that the second abutting surface 86 abuts against the first abutting surface 20 at the required angle, thereby changing the included angle between the first display unit 1 and the second display unit 4.

[0067] When unlocking is required: Press the drive unit 73 again to unlock the locking part 71 from the slot. Then, turn the handle part 82 of the lock case 58 away from the first fixing block 30 to release the tension between the lock case 58 and the second fixing block 61. Then, lift the handle part 82 of the lock case 58 and press down the second wrench 53 to make the tensioning column 55 swing away from the lock groove 19, so that the tensioning column 55 disengages from the lock groove 19 and unlocks the lock.

[0068] According to the present invention, compared with the prior art, the angle between the main abutment surface on the hook 18 and the mounting surface 31 on the first fixing block 30 of the LED display screen is adjustable. When the latch 52 and the lock groove 19 are locked, the second abutment surface 86 of the lock body 51 abuts against the first abutment surface 20, so that the angle between the second abutment surface 86 and the mounting surface 31 also changes. Since the bearing block 10 with the second abutment surface 86 is connected to the second display screen unit 4, and the first fixing block 30 with the mounting surface 31 is connected to the first display screen unit 1, the angle between the first display screen unit 1 and the second display screen unit 4 can be adjusted, thereby adjusting the curvature of the LED display screen and improving the applicability of the LED display screen.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
