Technical Field

[0001] This utility model relates to the field of LED screen locking technology, and in particular to a locking structure for LED screen splicing. Background Technology

[0002] LED screens are a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to their high brightness, wide viewing angle, and long lifespan, they are widely used in products such as outdoor advertising screens. In some large-scale advertising screens, multiple LED screens are usually spliced ​​together, and locking devices are used to fix the LED screens together.

[0003] LED screens come in various sizes, and to ensure that the locking devices can effectively secure two LED screens during splicing, the positions of the pre-drilled fixing holes for different sizes of LED screens are usually different. However, existing LED screen locking devices cannot flexibly adjust the positions of the fixing seats at both ends, resulting in an inability to accurately fit the fixing holes of LED screens of different sizes.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0007] Both sides of the main body are provided with locking plates that can move relative to the track. One side of the movable column is provided with an array of teeth along its length. The main body is also provided with a first elastic element that acts on the locking plates. The first elastic element can provide a thrust to push the locking plates to move into the track, so that the end of the locking plates can engage with the teeth to fix the movable column in the track.

[0008] A locking handle is provided at the lower end of the main body. Pressing the locking handle can move the locking plate away from the track and separate the end of the locking plate from the teeth.

[0009] As a further embodiment of this utility model: an L-shaped locking hook is also provided inside the main body, and a pin is provided on the corner end of the locking hook so that the locking hook can rotate around the pin at the corner end as an axis.

[0010] One end of the locking plate has a movable groove, and both ends of the locking handle have upper tops extending into the interior of the main body. One end of the locking hook is inserted into the movable groove and abuts against the inner wall of the movable groove near the locking hook. The lower end face of the other side of the locking hook abuts against the top of the upper top.

[0011] As a further embodiment of this utility model: the first fixed base is rotatably connected to the connecting part, and the second fixed base is rotatably connected to one end of the movable column.

[0012] As a further embodiment of this utility model: the first elastic element is a helical spring, and there are locking blocks on both sides of the locking plate. The first elastic element is sleeved on the outside of the locking plate, and the locking blocks are located within the surrounding interval of the first elastic element.

[0013] As a further embodiment of this utility model: the end of the locking piece is provided with a tooth that is adapted to the tooth.

[0014] As a further embodiment of this utility model: a limiting groove is provided on the locking plate, and a limiting rod is provided inside the main body, the limiting rod being inserted into the limiting groove.

[0015] As a further embodiment of this utility model: a nut groove is provided at the bottom of the main body, a through hole is provided at the lower end of the nut groove, a bolt sleeve is provided on the locking handle, a connecting bolt is provided inside the main body, the threaded part of the connecting bolt passes through the through hole and is screwed and fixed inside the bolt sleeve, and the nut of the connecting bolt is fitted into the nut groove.

[0016] As a further embodiment of this utility model: an abutment groove is provided at the top of the upper end, and one end of the locking hook abuts against the abutment groove.

[0017] As a further embodiment of this utility model: the inner wall of the track is provided with a groove, a second elastic element is provided in the groove, a limiting ball is provided at the opening of the groove, and the second elastic element is connected to the limiting ball;

[0018] The movable column has an array of arc-shaped notches on one side, and the second elastic element can push the limiting ball to abut against the arc-shaped notches.

[0019] As a further embodiment of this utility model: an observation groove is provided on the connecting part, and a scale line is provided on the movable column, with the observation groove aligned with the scale line.

[0020] Compared with the prior art, the beneficial effects of this technical solution are as follows: By pressing the locking handle, the locking plate inside the main body moves away from the track, so that the end of the locking plate separates from the teeth on one side of the movable column. At this time, the movable column can move in the track. According to the distance between the fixing holes on the back of the two LED screens, the distance between the first fixing seat and the second fixing seat can be changed by pushing and pulling the movable column. When the position is adjusted properly, the locking handle is released, the first elastic element elastically recovers and applies a pushing force to the locking plate, so that the end of the locking plate re-engages with the corresponding teeth, thereby fixing the position of the movable column in the track again. This realizes the flexible adjustment of the distance between the first fixing seat and the second fixing seat, so as to accurately fit the fixing holes of the LED screen when splicing and fixing LED screens of different sizes.

[0021] By using a rotatable locking hook, the two ends of the hook abut against the top of the locking handle and the movable groove of the locking plate, respectively. When the locking handle is pressed, the locking hook rotates, which in turn causes the locking plate to move horizontally. This allows the end of the locking plate to separate from the teeth of the movable column, enabling the movable column to move along the track to adjust the distance between the first and second fixed seats. This adapts to the splicing and fixing of LED screens of different sizes. After adjustment, releasing the pressure on the locking handle allows the end of the locking plate to reset and re-engage with the teeth using the elastic restoring force of the first elastic element, thereby fixing the distance between the first and second fixed seats.

[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 1-9A locking structure for splicing LED screens includes a U-shaped body 1. The U-shaped body 1 includes a main body 11 and connecting parts 12 at both ends of the main body 11. A track 13 with an opening is formed in the connecting part 12. A fixing seat 2 is provided at the end of the connecting part 12 away from the opening. A movable column 3 is slidably provided in the track 13. A fixing seat 4 is provided at the end of the movable column 3 away from the U-shaped body 1. By inserting the two movable columns 3 into the track 13, an LED screen locking device is assembled. When it is necessary to splice and fix two LED screens, the fixing seats 2 and 4 at the ends of the connecting part 12 and the movable column 3 are aligned with the fixing holes on the back of the two LED screens. Then, bolts are screwed in to fix the fixing seats 2 and 4 to the two LED screens respectively, thereby splicing and fixing the two LED screens.

[0037] Both sides of the main body 11 are provided with locking plates 5 that can move relative to the track 13. The movable column 3 has an array of teeth 31 arranged along its length on one side. The main body 11 is also provided with a first elastic element 6 that acts on the locking plate 5. The first elastic element 6 can provide a thrust to push the locking plate 5 into the track 13, so that the end of the locking plate 5 can engage with the teeth 31 to fix the movable column 3 in the track 13.

[0038] A locking handle 7 is provided at the lower end of the main body 11. Pressing the locking handle 7 can move the locking piece 5 away from the track 13, causing the end of the locking piece 5 to separate from the teeth 31.

[0039] Specifically, by pressing the locking handle 7, the locking plate 5 inside the main body 11 moves away from the track 13, causing the end of the locking plate 5 to separate from the teeth 31 on one side of the movable column 3. At this time, the movable column 3 can move within the track 13. According to the distance between the fixing holes on the back of the two LED screens, the movable column 3 can be pushed and pulled to change the distance between the fixing seat 1 2 and the fixing seat 2 4. When the position is adjusted properly, the locking handle 7 is released, the first elastic element 6 elastically recovers, and a pushing force is applied to the locking plate 5, so that the end of the locking plate 5 re-engages with the corresponding teeth 31, thereby fixing the position of the movable column 3 within the track 13 again. This achieves flexible adjustment of the distance between the fixing seat 1 2 and the fixing seat 2 4, so as to accurately fit the fixing holes of the LED screen when splicing and fixing LED screens of different sizes.

[0040] Based on the above embodiments, it is further proposed that an L-shaped locking hook 8 is also provided inside the main body 11, and a pin 81 is provided on the corner end of the locking hook 8, so that the locking hook 8 can rotate with the pin 81 at the corner end as the axis.

[0041] The locking plate 5 has a movable groove 51 at one end, and the locking handle 7 has an upper top end 71 extending into the body 11 at both ends. One end of the locking hook 8 is inserted into the movable groove 51 and abuts against the inner wall of the movable groove 51 near the locking hook 8. The lower end face of the other side of the locking hook 8 abuts against the top end of the upper top end 71.

[0042] Specifically, when the locking handle 7 is pressed into the body 11, the upper tops 71 at both ends of the locking handle 7 push one end of each of the two locking hooks 8 upwards. As one end of the locking hook 8 is pushed by the upper tops 71, it rotates around the pin 81. The rotation causes the other end of the locking hook 8 to rotate inwards toward the center of the body 11. Since this end abuts against the inner wall of the movable groove 51 of the locking plate 5, the rotational movement of the locking hook 8 can be converted into a translational movement of the locking plate 5. When the locking plate 5 is translated, its end separates from the teeth 31. At this time, the movable column 3 can move on the track 13 to adjust the distance between the fixed seat 1 2 and the fixed seat 2 4.

[0043] While the locking plate 5 is moving horizontally, it will also squeeze the first elastic element 6. After the distance between the first fixed seat 2 and the second fixed seat 4 is adjusted appropriately, the pressure on the locking handle 7 is released. At this time, the elastic force of the first elastic element 6 is released, causing the locking plate 5 to move into the track 13 and its end to engage with the corresponding tooth 31 again. When the locking plate 5 moves into the track 13, its movable groove 51 will drive one end of the locking hook 8, so that the end that abuts against the inner wall of the locking hook 8 will rotate and reset. Then the other end of the locking hook 8 will rotate and press down on the top end 71, so that the locking handle 7 moves down and resets.

[0044] In particular, whether the top end 71 moves upward or the end of the lock hook 8 rotates due to the movement of the lock plate 5, the two ends of the lock hook 8 will not disengage from the top end 71 and the movable groove 51 of the lock plate 5. The limiting method can be, for example, by adjusting the maximum upward movement distance of the locking handle 7 to control the end of the lock hook 8 to always remain in contact with the top end 71. No further restrictions or descriptions are given here.

[0045] In summary, this utility model, through the setting of the rotatable locking hook 8, allows the two ends of the locking hook 8 to abut against the upper top 71 of the locking handle 7 and the movable groove 51 of the locking plate 5, respectively. This allows the rotation of the locking hook 8 to be converted into the translation of the locking plate 5 by pressing the locking handle 7, which enables the end of the locking plate 5 to separate from the teeth 31 of the movable column 3. This allows the movable column 3 to move on the track 13 to adjust the distance between the first fixed seat 2 and the second fixed seat 4, thus adapting to the splicing and fixing of LED screens of different sizes. After adjustment, releasing the pressure on the locking handle 7 allows the end of the locking plate 5 to reset and re-engage with the teeth 31 using the elastic restoring force of the first elastic element 6, thereby fixing the distance between the first fixed seat 2 and the second fixed seat 4.

[0046] In this utility model, the locking handle 7 is located at the lower end of the main body 11. That is, after the fixing seat 1 2 and the fixing seat 2 4 are fixed to the two LED screens respectively, the locking handle 7 faces the LED screen, and there is enough distance between the main body 11 and the LED screen to allow the worker to insert his finger to press the locking handle 7.

[0047] Preferably, the first elastic element 6 is a helical spring, and there are locking blocks 52 on both sides of the locking plate 5. The first elastic element 6 is sleeved on the outside of the locking plate 5, and the locking blocks 52 are located within the surrounding interval of the first elastic element 6.

[0048] Specifically, by providing a locking block 52 on the locking plate 5 that is locked within the surrounding interval of the first elastic element 6, the locking plate 5 can squeeze the first elastic element 6 when it is translated, and at the same time, the first elastic element 6 can act on the locking plate 5 when it releases its elastic force.

[0049] Preferably, an abutment groove 72 is provided at the top of the upper end 71, and one end of the locking hook 8 abuts against the abutment groove 72; by using the abutment groove 72, the end of the locking hook 8 abutting against the upper end 71 can be limited, so as to prevent the end of the locking hook 8 from shifting to the left or right.

[0050] Preferably, a nut groove 14 is provided at the bottom inner part of the main body 11, and a through hole 15 is provided at the lower end of the nut groove 14. A bolt sleeve 73 is provided on the locking handle 7, and a connecting bolt 9 is provided inside the main body 11. The threaded part of the connecting bolt 9 passes through the through hole 15 and is screwed and fixed inside the bolt sleeve 73, and the nut of the connecting bolt 9 is fitted into the nut groove 14. The connecting bolt 9 is screwed to the bolt sleeve 73 on the locking handle 7 through the through hole 15 by its threaded part, and the nut of the connecting bolt 9 is restricted by the nut groove 14, thereby fixing the locking handle 7 to the lower end of the main body 11, while not restricting the up and down movement of the locking handle 7 when it is pressed.

[0051] Preferably, the locking piece 5 has a limiting groove 53, and the main body 11 has a limiting rod 111. The limiting rod 111 is inserted into the limiting groove 53. Through the cooperation of the limiting groove 53 and the limiting rod 111, the locking piece 5 can be guided, thereby limiting the position and movement trajectory of the locking piece 5. The main body 11 has a cavity inside, and there is a connection between the cavity and the track 13. The locking piece 5 enters the track 13 through the connection.

[0052] Preferably, the end of the locking plate 5 is provided with a tooth 54 that is adapted to the tooth 31. The locking plate 5 fixes the movable column 3 in the track 13 by the engagement of the tooth 31 with the tooth 54.

[0053] In some embodiments, the first fixing seat 2 is rotatably connected to the connecting part 12, and the second fixing seat 4 is rotatably connected to one end of the movable column 3. The first fixing seat 2 and the second fixing seat 4 are rotatably configured to flexibly adapt to some curved LED screens, fit into the curved LED screen, and facilitate the connection of the LED screen.

[0054] In some embodiments, the inner wall of the track 13 is provided with a slot 16, a second elastic element 10 is provided in the slot 16, and a limiting ball 101 is provided at the opening of the slot 16. The second elastic element 10 is connected to the limiting ball 101.

[0055] The movable column 3 has an array of arc-shaped notches 32 on one side, and the second elastic element 10 can push the limiting ball 101 to abut against the arc-shaped notches 32.

[0056] Specifically, after pressing the locking handle 7 to separate the locking plate 5 from the teeth 31, the movable column 3 can freely extend and retract within the track 13. However, the lack of a limit switch makes it difficult to accurately align the two movable columns 3 when operating their positions. Therefore, a limit ball 101, pushed by the second elastic element 10, engages with the arc-shaped notch 32 on the movable column 3. Multiple arc-shaped notches 32 are arranged in an array. When the movable column 3 is pushed or pulled, the limit ball 101 is pushed back into the slot 16. After the positions of the two movable columns 3 are adjusted in sequence, the second elastic element 10 pushes the limit ball 101 to abut against the corresponding arc-shaped notch 32, thereby providing basic limit fixation for the two movable columns 3. Then, the locking handle 7 is released, allowing the locking plate 5 to re-engage with the teeth 31 to fix the positions of the two movable columns 3, thus making the positions of the two movable columns 3 consistent, improving the convenience of adjusting the movable columns 3, and making the operation simpler and faster.

[0057] The second elastic element 10 is a spring.

[0058] Furthermore, the connecting part 12 is provided with an observation groove 17, and the movable column 3 is provided with a scale line 33. The observation groove 17 is aligned with the scale line 33. Through the setting of the scale line 33 and the observation groove 17, the worker can more intuitively see the position of the movable column 3 so as to align the positions of the two movable columns 3.

[0059] Preferably, the U-shaped body 1 includes a U-shaped upper cover 18 and a U-shaped lower cover 19, wherein the U-shaped upper cover 18 and the U-shaped lower cover 19 are assembled to form the main body 11 and the connecting part 12.

[0060] 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.
