Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0037] Please see Figures 1 to 15As shown, the present invention provides the following technical solution: an LED screen curvature clamping device 1000, comprising two sets of clamping devices 100 and a curvature adjustment device 200, wherein the curvature adjustment device 200 is connected to the two sets of clamping devices 100; each set of clamping devices 100 includes a clamping base 10, two sets of clamping components 20 and two sets of clamping members 30, wherein the two sets of clamping components 20 are distributed on both sides of the clamping base 10, and the two sets of clamping members 30 are distributed and installed on two LED screens 2000, and the two sets of clamping components 20 are respectively used to clamp the two sets of clamping members 30 distributed and installed on the two LED screens 2000; the curvature adjustment device 200 includes a curvature adjustment component 40 and a locking component 50, wherein the two ends of the curvature adjustment component 40 are respectively connected to the two sets of clamping devices 100, and the locking component 50 is installed on the curvature adjustment component 40, and the locking component 50 is used to lock the curvature adjustment component 40.

[0038] The LED screen curvature clamping device 1000 provided in this embodiment includes two sets of clamping devices 100 and a curvature adjustment device 200. Each set of clamping devices 100 clamps two sets of clamping components 30 distributed on two LED screens 2000 respectively through two sets of clamping components 20. Thus, each set of clamping devices 100 can assemble two LED screens 2000. The curvature adjustment device 200 is connected to the two sets of clamping devices 100, so the two sets of clamping devices 100 together assemble four LED screens 2000. The curvature adjustment device 200 is used to adjust the installation curvature between the two LED screens 2000 assembled by one set of clamping devices 100 and the two LED screens 2000 assembled by the other set of clamping devices 100. When the curvature adjustment device 200 adjusts the installation curvature between two screens assembled by one set of clamping devices 100 and two screens assembled by another set of clamping devices 100, since the two ends of the curvature adjustment device 200 are respectively connected to two sets of clamping devices 100, the user can simultaneously stretch the two sets of clamping devices 100 connected to the two ends of the curvature adjustment device 200 to the outward sides. At this time, the curvature adjustment component 40 in the curvature adjustment device 200 will extend to both ends of the curvature due to the pulling force of the clamping devices 100 at both ends, thereby adjusting the curvature between the two sets of clamping devices 100, and thus adjusting the corresponding installation curvature between the two LED screens 2000 assembled by one set of clamping devices 100 and the two LED screens 2000 assembled by another set of clamping devices 100. In this invention, four LED screens 2000 are assembled together by two clamping devices 100, resulting in high assembly efficiency. Furthermore, the curvature adjustment device 200 can adjust the corresponding installation curvature between two LED screens 2000 assembled by one set of clamping devices 100 and two LED screens 2000 assembled by another set of clamping devices 100. Thus, the curvature adjustment device 200 can support the corresponding curvature installation between the LED screens 2000, which is both efficient and convenient.

[0039] Please see Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the curvature adjustment assembly 40 includes a curvature adjustment plate 402, two curvature support plates 401, an adjustment block 403, and a movable bead 4032. The two curvature support plates 401 are arranged adjacent to each other. One end of the curvature adjustment plate 402 is located between the two curvature support plates 401, and the other end of the curvature adjustment plate 402 is connected to two sets of clamping devices 100 respectively. The adjustment block 403 is fixed between the two curvature support plates 401, and the adjustment block 403 is located between the two curvature support plates 401. In the plate groove 4021 opened in the middle of the section plate 402, the top of the adjusting block 403 is elastically provided with a movable bead 4032, and the top groove wall of the plate groove 4021 is provided with several bead grooves 4022. The movable bead 4032 elastically abuts against the bead grooves 4022. The interior of the adjusting block 403 is provided with an elastic element 4031, which is elastically connected to the movable bead 4032. The top of the arc adjusting plate 402 is provided with several engagement grooves 4023, which are used to engage with the locking component 50.

[0040] In specific implementation: When the user simultaneously stretches the two sets of clamping devices 100 connected to both ends of the arc adjustment device 200 outwards, when the arc adjustment component 40 in the arc adjustment device 200 is subjected to tension, the movable beads 4032 on the adjustment block 403 fixed between the two arc plates pass through several bead grooves 4022 opened on the top groove wall of the plate groove 4021 in the arc adjustment plate 402. The adjustment block 403 is provided with an elastic element 4031 to elastically connect the movable beads 4032. The movable beads 4032 can elastically pass through several bead grooves 4022 in sequence, thereby pulling the distance between the two arc support plates 401 and the arc adjustment plate 402, so as to realize the arc adjustment component 40 extending to both ends of the arc. During the process of the arc adjustment component 40 extending to both ends of the arc, the corresponding installation arc between the two LED screens 2000 assembled by one set of clamping devices 100 and the two LED screens 2000 assembled by the other set of clamping devices 100 is adjusted. With this configuration, the curvature adjustment component 40 in the curvature adjustment device 200 can effectively adjust the corresponding installation curvature between the two LED screens 2000 assembled by one set of clamping devices 100 and the two LED screens 2000 assembled by another set of clamping devices 100.

[0041] Please see Figure 4 , Figure 6 , Figure 7As shown, in some embodiments, the locking assembly 50 is mounted on two curved support plates 401. The locking assembly 50 includes an operating handle 501, a housing 502, two rotating disks 5021, a transmission rod 503, and a locking block 504. The two rotating disks 5021 are rotatably disposed on both sides of the housing 502. The operating handle 501 is connected to the two rotating disks 5021. The transmission rod 503 is fixed between the edges of the two rotating disks 5021. The housing 502 has a cavity inside, and the locking block 504 is accommodated in the cavity. The transmission rod 503 passes through the top of the locking block 504. The bottom of the locking block 504 is provided with a plurality of meshing teeth 5041, which are used to mesh with the meshing groove 4023.

[0042] In specific implementation: When both ends of the arc adjustment component 40 are adjusted to the desired arc, the locking component 50 needs to be operated to lock the adjusted arc of the arc adjustment component 40. The user can rotate the operating handle 501 counterclockwise by hand. When the operating handle 501 rotates counterclockwise, it drives the two rotating disks 5021 to rotate counterclockwise. When the two rotating disks 5021 rotate counterclockwise, they drive the transmission rod 503 to rotate counterclockwise along the edges of the two rotating disks 5021 and descend. When the transmission rod 503 descends, it drives the locking block 50. 4. As the locking block 504 descends, the meshing teeth 5041 at the bottom of the locking block 504 engage with the meshing groove 4023 at the top of the curvature adjustment plate 402, thereby locking the curvature adjustment plate 402 with the locking assembly 50. Since the locking assembly 50 is mounted on the two curvature support plates 401, while locking the curvature adjustment plate 402, the two curvature support plates 401 are fixed to the locking assembly 50, thus preventing them from being pulled apart. This design allows the locking assembly 50 to effectively lock and fix the curvature adjusted by the curvature adjustment assembly 400 after the curvature adjustment assembly 400 has adjusted the curvature of the two clamping devices 100.

[0043] Please see Figure 7 , Figure 8 As shown, in some embodiments, a push rod 5011 is slidably connected to the operating handle 501, and a retaining groove 5022 is provided on the housing 502 facing the push rod 5011, and the retaining groove 5022 is movably engaged with the push rod 5011.

[0044] In practice: After the user controls the locking component 50 via the operating handle 501 to lock and fix the adjusted curvature of the curvature adjustment component 40, the user can manually push the push rod 5011 on the operating handle 501 towards the receiving groove 5022 until one end of the push rod 5011 engages and is fixed with the receiving groove 5022, thereby fixing the operating handle 501. This design ensures that after the locking component 50 locks the curvature adjustment component 40, the operating handle 501 is fixed, thus fixing the state of the locking component 50 in the curvature adjustment component 40.

[0045] Please see Figure 10 , Figure 11 , Figure 13 As shown, in some embodiments, the clamping assembly 20 includes a handle 201, a housing 202, a guide 203, and a clamping member 204. The guide 203 is movably disposed on the housing 202, and the clamping member 204 is movably disposed in a receiving cavity 2021 provided inside the housing 202. The clamping member 30 is embedded in the receiving cavity 2021 from the bottom of the clamping seat 10. The cavity wall of the receiving cavity 2021 is movably abutted against the wall of the clamping member 204. The receiving cavity 2021 gradually widens from top to bottom. One end of the handle 201 is throttledly connected to the guide 203, and the guide 203 is throttledly connected to the clamping member 204. The handle 201 is used to drive the guide 203 to guide the clamping member 204 to clamp the clamping member 30 or to release the clamping member 30.

[0046] In practice: the user can hold the handle 201 and rotate it counterclockwise. Then, the handle 201 will drive the clamping member 204 to rise through the transmission guide 203. During the rising process, the two sides of the clamping member 204 will move and abut against the two sides of the cavity wall of the gradually narrowing receiving cavity 2021 and be squeezed together. Thus, the clamping member 204 set in the receiving cavity 2021 will clamp the clamping member 30 embedded in the receiving cavity 2021 during the closing process, and the clamping assembly 20 will fix the LED screen 2000. When the clamping assembly 20 releases the clamping member 30 from the LED screen 2000, the user can rotate the handle 201 clockwise. The handle 201 then guides the clamping member 204 to descend via the transmission guide 203. During this descent, the sides of the clamping member 204 extend and open as they move against the sides of the gradually widening receiving cavity 2021. This releases the clamping member 30 embedded in the receiving cavity 2021, thus releasing the clamping assembly 20 from the LED screen 2000. This design allows the clamping assembly 20 to effectively clamp the clamping member 30 on the LED screen 2000, thereby effectively securing the LED screen 2000.

[0047] Please see Figure 13 , Figure 14 , Figure 15 As shown, in some embodiments, the guide member 203 includes two turntables 2031 and a guide rod 2032. The two turntables 2031 are rotatably disposed on both sides of the housing 202. One end of the handle 201 is connected to the two turntables 2031 in a transmission manner. The guide rod 2032 is fixed between the edges of the two turntables 2031. The clamping member 204 includes a first clamping body 2041 and a second clamping body 2042. The first clamping body 2041 movably accommodates the second clamping body 2042. The bottom of the first clamping body 2041 and the bottom of the second clamping body 2042 are both provided with a hook portion 2044. The top of the second clamping body 2042 is provided with a guide groove 20421, and the guide rod 2032 passes through the guide groove 20421.

[0048] In specific implementation: When the guide member 203 guides the clamping member 204 to rise and close to clamp the clamping member 30 on the LED screen 2000, the user holds the handle 201 and rotates it counterclockwise. Then, the handle 201 drives the two turntables 2031 to rotate counterclockwise. When the two turntables 2031 rotate counterclockwise, they drive the guide rod 2032 to rotate counterclockwise along the edges of the two turntables 2031 and rise. When the guide rod 2032 rises, it guides the second clamping body 2042 to rise. Since the first clamping body 2041 movably accommodates part of the second clamping body 204, 2. When the second clamp 2042 rises, it simultaneously drives the first clamp 2041 to rise. During the simultaneous rise of the first clamp 2041 and the second clamp 2042, the first clamp 2041 and the second clamp 2042 move against the sides of the cavity wall of the gradually narrowing receiving cavity 2021 and are squeezed together. After the first clamp 2041 and the second clamp 2042 are closed, the hooks 2044 provided at the bottom of the first clamp 2041 and the bottom of the second clamp 2042 cooperate to hook and clamp the clamping part 30 on the LED screen 2000. When the guide member 203 guides the clamping member 204 to descend and open, thus releasing the clamping member 30 on the LED screen 2000, the user holds the handle 201 and rotates it clockwise. The handle 201 then drives the two turntables 2031 to rotate clockwise. As the two turntables 2031 rotate clockwise, the guide rod 2032 rotates clockwise along the edges of the two turntables 2031 and descends. When the guide rod 2032 descends, it guides the second clamping body 2042 to descend. Since the first clamping body 2041 movably accommodates part of the second clamping body 2042, the second clamping body 2042... As the second clamp 2042 descends, it simultaneously lowers the first clamp 2041. During this descent, the first and second clamps 2041 move and abut against the sides of the gradually widening receiving cavity 2021, extending and opening. After opening, the hooks 2044 at the bottom of both clamps simultaneously open to release the clamping member 30 on the LED screen 2000. This design allows the guide member 203, driven by the handle 201, to effectively guide the clamping member 204 to clamp or release the clamping member 30 on the LED screen 2000.

[0049] Please see Figure 13 , Figure 14 , Figure 15 As shown, in some embodiments, the wall of the clamping member 204 is configured as a polygon that gradually widens from top to bottom, and the cavity wall of the receiving cavity 2021 is configured as a polygon that can movably abut against the wall of the clamping member 204 and gradually widens from top to bottom.

[0050] In practice: When the user rotates the handle 201 counterclockwise to drive the guide 203 to guide the clamping member 204 upward, the polygonal shape of the clamping member 204, which gradually widens from top to bottom, can move and abut against the polygonal shape of the cavity wall of the receiving cavity 2021, which also gradually widens from top to bottom. This allows the sides of the clamping member 204 to be pressed against and squeezed by the upwardly narrowing cavity wall of the receiving cavity 2021, thus achieving a clamping action. When the user rotates the handle 201 clockwise to drive the guide 203 to guide the clamping member 204 downward, the polygonal shape of the clamping member 204, which gradually widens from top to bottom, can move and abut against the polygonal shape of the cavity wall of the receiving cavity 2021, which also gradually widens from top to bottom. This allows the sides of the clamping member 204 to extend and open towards the downwardly widening cavity wall of the receiving cavity 2021, thus canceling the clamping action. With this configuration, the wall of the clamping member 204 can be moved against the cavity wall of the receiving cavity 2021, thereby enabling the clamping member 204 to complete the clamping action or cancel the clamping action.

[0051] Please see Figure 14 As shown, in some embodiments, the housing 202 has two limiting blocks 205 connected inside, and the two limiting blocks 205 are respectively located in the limiting grooves 2043 opened on the first clamping body 2041 and the second clamping body 2042.

[0052] In specific implementation: the two limiting blocks 205 are used to abut and limit the first clamping body 2041 and the second clamping body 2042 in the clamping member 204 when they reach the matching position during the upward or downward movement. This arrangement allows the two limiting blocks 205 to limit the movement of the first clamping body 2041 and the second clamping body 2042 in the clamping member 204, thereby preventing excessive movement of the first clamping body 2041 and the second clamping body 2042 and potential misalignment or damage.

[0053] Please see Figure 9 , Figure 10 As shown, in some embodiments, the clamping member 30 includes a clamping base 301, a clamping post 302, and two fixing posts 303. The two fixing posts 303 are respectively disposed on both sides of the clamping post 302. Each of the two fixing posts 303 has a screw hole 3031. The clamping post 302 is disposed on the clamping base 301 and located between the two fixing posts 303. The surface of the clamping post 302 has an annular groove 3021.

[0054] In specific implementation: When the clamping component 30 is installed on the LED screen 2000, screws are inserted into the screw holes 3031 on the fixing posts 303 on both sides of the clamping base 301 to fix it to the frame of the LED screen 2000. The annular groove 3021 on the clamping post 302 is used for the hook portions 2044 provided at the bottom of both the first clamping body 2041 and the bottom of the second clamping body 2042 to cooperate and clamp. With this arrangement, the clamping assembly 20 can effectively clamp the clamping component 30 on the LED screen 2000.

[0055] Please see Figure 12 , Figure 13 As shown, in some embodiments, a push rod 2011 is slidably connected to the handle 201, and a slot 2022 is provided on the housing 202 facing the push rod 2011, the slot 2022 being movably engaged with the push rod 2011.

[0056] In practice: After the user operates the handle 201 to rotate counterclockwise, the transmission guide 203 guides the clamping member 204 to rise and close, clamping the supply clamping member 30. Then, the user can manually push the push rod 2011 on the handle 201 towards the slot 2022 until one end of the push rod 2011 engages with the slot 2022, thus fixing the handle 201. This design allows the user to control the clamping member 204 to clamp the supply clamping member 30 by operating the handle 201, and then push the push rod 2011 on the handle 201 to engage with the slot 2022 to fix the clamping member 204 in the clamping state of the supply clamping member 30.
