Description
Technical Field
[0001] This utility model relates to the field of LED display equipment technology, and in particular to an easily adjustable arc-shaped lock for LED screen splicing. Background Technology
[0002] LED displays are display devices that use LED light-emitting arrays to create images. They feature high brightness, long lifespan, good color reproduction, and wide environmental adaptability, and are widely used in outdoor advertising, stage backdrops, monitoring centers, and other scenarios. Curved LED displays, on the other hand, are based on flat screens but use special structural designs to create a curved surface, providing a more immersive visual experience and adapting to special installation environments such as curved building facades and circular exhibition halls.
[0003] In curved LED display splicing, the arc lock is a core connector. Through its locking structure and engagement with the mounting holes of the screen units, it precisely controls the curvature and angle of adjacent units, ensuring a smooth and continuous curved surface after splicing, without noticeable gaps or protrusions. Simultaneously, the arc lock possesses strong load-bearing and fixing capabilities, guaranteeing the structural stability of the curved screen during long-term use. It is a key component for achieving precision and reliability in curved splicing.
[0004] Curved LED displays come in various sizes, and to ensure the locking mechanism's effectiveness during splicing, the positions of the pre-drilled fixing holes often differ for different screen sizes. However, existing LED screen locking mechanisms have significant limitations: they are difficult to assemble, and it is hard to flexibly adjust the positions of the fixing brackets at both ends to fit different sizes of LED screens. Even if some locking mechanisms have adjustment functions, they mostly use the traditional screw-type locking method, which is cumbersome to operate, inconvenient, and costly, and cannot efficiently meet the splicing and fixing requirements.
[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0009] The two tracks are provided with racks on one side facing the control unit, and locking plates are provided on both sides inside the control space. The locking plates can extend into the assembly space and engage with the racks, and a rope is connected between the two locking plates.
[0010] A locking button is provided on the outside of the control unit. The end of the locking button extends into the control space and abuts against the rope. A first elastic element is also provided inside the control space. The first elastic element can use elastic force to push the locking plate to move towards the assembly unit.
[0011] As a further embodiment of this utility model: the incline body includes an incline top cover, a locking cover plate, and track cover plates on both sides;
[0012] The locking cover and the middle section of the U-shaped top cover form a control unit and create a control space;

The locking button includes a pressing part, which passes through the movable opening and is provided with a limiting ring that matches the limiting groove. A push post is provided at the upper end of the pressing part after passing through the movable opening, and the upper end of the push post abuts against the rope.
[0015] As a further embodiment of this utility model: the control space is provided with an upper cover plate connected to the locking cover plate, the upper cover plate is located above the limiting groove, and the upper cover plate is provided with a through hole corresponding to the push post, the push post can pass through the through hole, and the upper end of the push post is provided with a cable limiting groove, the corresponding section of the rope is located in the cable limiting groove.
[0016] As a further embodiment of this utility model: a second elastic element is provided between the upper end of the pressing part and the upper cover plate.
[0017] As a further embodiment of this utility model: a limiting pin is also provided inside the control space, and the lower end of the limiting pin abuts against the rope, so that the rope is located between the limiting pin and the push post.
[0018] As a further embodiment of this utility model: the rope is a steel wire rope, and each of the two locking plates is provided with a connecting hole. The two ends of the rope are fixed to the connecting holes through fixed terminals.
[0019] As a further embodiment of this utility model: the first elastic element is a spring and is sleeved on the outside of the locking plate. The locking plate is provided with a locking block, which is located within the surrounding interval of the first elastic element.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figure 1-8 An adjustable arc-shaped lock for LED screen splicing includes a chamfered body 1, a control part 2 and assembly parts 3 at both ends of the control part 2, an assembly space 4 on the assembly part 3, and a control space 5 inside the control part 2 that is connected to the assembly space 4.
[0037] It also includes a track 6, one end of which is retractably disposed within the assembly space 4, and the other end is rotatably disposed with a first fixed seat 7, and the end of the assembly part 3 away from the track 6 is rotatably disposed with a second fixed seat 8.
[0038] Preferably, by inserting two rails 6 into the assembly space 4, an LED screen locking component is assembled. When it is necessary to splice and fix two LED screens, the first fixing seat 7 and the second fixing seat 8 at the end of the rails 6 and the assembly part 3 are aligned with the fixing holes on the back of the two LED screens. Then, screws are screwed in, so that the first fixing seat 7 and the second fixing seat 8 are respectively fixed to the two LED screens, thereby splicing and fixing the two LED screens.
[0039] Two tracks 6 are provided with racks 9 on one side facing the control unit 2. Locking plates 10 are provided on both sides inside the control space 5. The locking plates 10 can extend into the assembly space 4 and mesh with the racks 9. A rope 11 is connected between the two locking plates 10.
[0040] A locking button 12 is provided on the outside of the control unit 2. The end of the locking button 12 extends into the control space 5 and presses against the rope 11. A first elastic element 13 is also provided inside the control space 5. The first elastic element 13 can use elastic force to push the locking plate 10 to move towards the assembly unit 3.
[0041] Specifically, during use, by pressing the locking button 12, the end of the locking button 12 pushes the rope 11, and the rope 11 drives the locking plates 10 on both sides inside the control space 5 to move towards the middle, so that the ends of the locking plates 10 separate from the rack 9. At this time, the track 6 located inside the assembly space 4 can be extended and retracted, realizing flexible adjustment between the first fixed seat 7 and the second fixed seat 8 to adapt to LED screens of different sizes. It can also be disassembled for easy disassembly and assembly.
[0042] After the position of track 6 is determined, release the locking button 12. At this time, the first elastic element 13 uses its rebound force to push the locking plate 10 to move towards the assembly part 3, so that the two locking plates 10 pull the rope 11 back to a straight state, allowing the end of the locking plate 10 to re-engage with the rack 9, thereby fixing the track 6 in the assembly space 4, and then fixing the position of the first fixing seat 7 and the second fixing seat 8. As the rope 11 returns to a straight state, it will press down the locking button 12, so that the locking button 12 is reset for the next adjustment operation.
[0043] Preferably, a connecting groove (not shown in the figure) is provided between the control space 5 and the assembly space 4 for the locking piece 10 to extend from the control space 5 into the assembly space 4. The length, width and height of the connecting groove are the same as the cross-sectional dimensions of the locking piece 10, which can limit the locking piece 10, allowing the locking piece 10 to maintain horizontal displacement during translation. Furthermore, after the locking piece 10 is translated towards the center and separated from the rack 9, its end is still in the connecting groove, ensuring the effectiveness of the limiting.
[0044] Furthermore, the end of the locking piece 10 has teeth that match the rack 9. When it moves toward the rack 9, the teeth will mesh with the rack 9, thereby fixing the position of the track 6.
[0045] In summary, this utility model connects two locking plates 10 via a rope 11. By pushing the rope 11 with the locking button 12, the rope 11 deforms, causing the two locking plates 10 to separate from the racks 9 on the two tracks 6, facilitating adjustment or disassembly of the tracks 6. After adjustment or disassembly (or after the tracks are inserted into the assembly space 4 in an assembled manner), simply releasing the locking button 12 allows the rebound force of the first elastic element 13 to push the locking plates 10 back to their original position and re-engage with the racks 9, fixing the positions of the tracks 6, the first fixing seat 7, and the second fixing seat 8. The locking button 12 is reset as the rope 11 is straightened. This design offers high ease of operation; a single press unlocks the track 6 for adjustment. After adjustment, the elastic reset mechanism automatically resets and locks the locking plates 10 and the locking button 12, replacing the traditional spiral locking method and reducing manufacturing and assembly costs.
[0046] Based on the above embodiments, it is further proposed that the C-shaped main body 1 includes a C-shaped top cover 14, a locking cover plate 15, and track cover plates 16 on both sides;
[0047] The middle section of the locking cover 15 and the U-shaped upper cover 14 together form the control part 2 and the control space 5;
[0048] The track cover 16 and the two sides of the U-shaped top cover 14 form the assembly part 3 and the assembly space 4.
[0049] Based on the above embodiments, it is further proposed that a limiting groove 17 is provided on the locking cover plate 15, and a movable opening 18 is provided at the lower end of the limiting groove 17. The locking button 12 includes a pressing part 19, which passes through the movable opening 18 and is provided with a limiting ring 20 that matches the limiting groove 17. After the upper end of the pressing part 19 passes through the movable opening 18, a push post 21 is provided, and the upper end of the push post 21 presses against the rope 11.
[0050] Specifically, the pressing part 19 serves as the area pressed by the user, causing the upper push post 21 to push against the rope 11. When the push post 21 is pushed down during the process of being straightened by the rope 11, the limiting ring 20 it is provided with will be restricted by the limiting groove 17 to prevent the pressing part 19 from disengaging from the movable opening 18.
[0051] Based on the above embodiments, it is further proposed that an upper cover plate 22 connected to the locking cover plate 15 is provided in the control space 5. The upper cover plate 22 is located above the limiting groove 17, and a through hole 23 corresponding to the push post 21 is opened on the upper cover plate 22. The push post 21 can pass through the through hole 23, and a cable limiting groove 24 is provided at the upper end of the push post 21. The corresponding section of the rope 11 is located in the cable limiting groove 24.
[0052] Specifically, by setting the upper cover plate 22, the push column 21 is guided and limited by the through holes 23 of the upper cover plate 22 to avoid deviation of the movement trajectory of the push column 21;
[0053] The cable-limiting groove 24 provided at the upper end of the push post 21 is used to limit the position of the rope 11, preventing the rope 11 from detaching from the push post 21, and as... Figure 2 and Figure 6 As shown, there are two pushers located on both sides of the upper end of the pressing part 19, which can strengthen the restraint of the rope 11 and prevent it from dislodging.
[0054] Based on the above embodiments, it is further proposed that a second elastic element 37 is provided between the upper end of the pressing part 19 and the upper cover plate 22.
[0055] Specifically, the second elastic element 37 can be a spring. When the user releases the pressure on the pressing part 19, the rebound force of the second elastic element 37 can push the pressing part 19 to quickly return to its original position. At the same time, under normal conditions, the second elastic element 37 continuously presses against the pressing part 19, which can prevent the pressing part 19 from moving on its own and pushing the rope 11, thereby causing the track 6 to move on its own.
[0056] Based on the above embodiments, it is further proposed that a limiting pin 25 is also provided inside the control space 5, and the lower end of the limiting pin 25 abuts against the rope 11, so that the rope 11 is located between the limiting pin 25 and the push post 21.
[0057] Specifically, such as Figure 2 As shown, three limit pins 25 are provided and are interspersed with two push pins 21. That is, each of the two push pins 21 is located in the middle of the limit pins 25. When the rope 11 is pushed up, the limit pins 25 can play a role in steering and limiting, allowing the two push pins 21 to quickly deform the rope 11 and pull it to the locking plate 10 for translation.
[0058] Based on the above embodiments, it is further proposed that the rope 11 is a steel wire rope, and each of the two locking plates 10 is provided with a connecting hole 26. The two ends of the rope 11 are fixed to the connecting hole 26 through a fixed terminal.
[0059] Specifically, the wire rope has the advantages of high tensile strength and good durability, and as a rope 11, its locking force is stable. The two ends of the rope 11 are fixed in the connection holes 26 opened on the locking plate 10 through fixed terminals.
[0060] Based on the above embodiments, it is further proposed that the first elastic element 13 is a spring and is sleeved on the outside of the locking piece 10. The locking piece 10 is provided with a locking block 27, which is located within the surrounding interval of the first elastic element 13.
[0061] The control space 5 is also equipped with a baffle 28, and the first elastic element 13 is located between the baffle 28 and the inner wall of the control space 5.
[0062] Specifically, the first elastic element 13 has the baffle 28 as its bottom surface. When the locking plate 10 moves, the locking plate 10 can compress the first elastic element 13 by means of the locking block 27, so that when the pressing part 19 is released, the first elastic element 13 can release the rebound force and push the locking plate 10 to reset.
[0063] Based on the above embodiments, it is further proposed that the end of the track 6 near the first fixed seat 7 is provided with a mounting jaw 29, the first fixed seat 7 is provided with a mounting plate 30, the mounting plate 30 is provided with a through hole 31, both ends of the mounting jaw 29 are provided with a first screw hole 32, and a bolt 33 is provided outside the mounting jaw 29. The bolt 33 is screwed into the two first screw holes 32, and the mounting plate 30 can be rotatably sleeved on the bolt 33 through the through hole 31.
[0064] Specifically, when installing the first fixing seat 7, the mounting plate 30 of the first fixing seat 7 is placed in the mounting jaw 29. Then, while turning the bolt 33 through the first screw hole 32 on the mounting jaw 29, the bolt 33 passes through the through hole 31 on the mounting plate 30. The mounting plate 30 can then rotate within the mounting jaw 29 through the through hole 31 to adjust the angle and match the curved screen. It should be noted that the bolt 33 may only have threads at the end for screwing into the first screw hole 32 on one side of the mounting jaw 29, so that the surface of the area contacted by the through hole 31 is smooth, making the first fixing seat 7 rotate more smoothly.
[0065] Based on the above embodiments, it is further proposed that an arc-shaped groove 34 is opened on one side of the mounting plate 30, and a second screw hole 35 is opened on one side of the mounting jaw 29. A screw rod 36 is screwed into the second screw hole 35, and rotating the screw rod 36 can make it abut against the inner wall of the arc-shaped groove 34.
[0066] Specifically, when adjusting the angle of the first fixed seat 7, the screw 36 screwed into the second screw hole 35 can be turned so that the screw 36 abuts against the inner wall of the arc groove 34 on one side of the mounting plate 30, thereby fixing the angle of the first fixed seat 7.
[0067] The installation and adjustment methods of the second fixed seat 8 and the assembly part 3 are the same as those of the first fixed seat 7 and the track 6, and will not be elaborated further here.
[0068] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
