In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0032] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0033] like Figures 1 to 8 As shown, according to the first aspect of the present application, the present application provides a connecting device 100, which is used for an LED display screen. The LED display screen includes a box frame 200. The connecting device 100 is installed on one of the box frames 200 of two adjacent LED display screens, and is used to achieve rapid splicing with the other box frame 200 of the two adjacent LED display screens, thereby solving the problem of rapid splicing of LED display screens.

[0034] It should be noted that the connecting device 100 can be directly fixed on the box frame 200, or the connecting device 100 can be fixed on other connecting structures, and then the connecting structure is fixed on the box frame 200. The connecting structure can be a built-in structure of the box frame 200, or an external structure of the box frame 200, and this application does not limit this.

[0035] In an optional embodiment, the connecting device 100 includes an adjustment component 102 and a connecting lock 101 for splicing two adjacent LED display screens. The adjustment component 102 is installed on the box frame 200, and the connecting lock 101 is at least partially movably passed through the adjustment component 102. The adjustment component 102 cooperates with the box frame 200 to adjust the radial clearance of the connecting lock 101 through the box frame 200 and the end face clearance between the connecting lock 101 and the box frame 200, so that the connecting lock 101 can be applied to box frames 200 of different thicknesses and box frames 200 with different hole sizes, thereby ensuring the splicing effect and display effect of the LED display screen.

[0036] Exemplarily, a mounting hole 201 is provided on the box frame 200, and the adjustment component 102 is at least partially arranged in the mounting hole 201, for limiting the aperture of the mounting hole 201, so as to limit the moving direction of the locking rod 20 of the connecting lock 101, so that the connecting lock 101 can be installed on the box frame 200 with different hole sizes; or, the adjustment component 102 is arranged on the connecting end surface between the connecting lock 101 and the mounting hole 201, for filling or adjusting the installation gap between the connecting lock 101 and the box frame 200, so as to control the axial stroke of the locking rod 20 of the connecting lock 101 along the mounting hole 201, thereby realizing the splicing of box frames 200 of different thicknesses.

[0037] It should be noted that the adjustment component 102 can also cooperate with the connecting lock 101 through a partial structure installed in the mounting hole 201 to control the axial stroke of the locking rod 20 along the mounting hole 201, so that the connecting lock 101 can adapt to box frames 200 of different thicknesses and realize splicing between box frames 200 of different thicknesses, so that the connecting lock 101 can be applied to the splicing between box frames 200 with different hole positions and thicknesses, and also ensure the display effect of the LED display.

[0038] In an optional embodiment, the connecting lock 101 includes a lock base 10 and a locking rod 20. The locking rod 20 is rotatable and axially movable on the lock base 10. The lock base 10 is installed on a box frame 200 of two adjacent LED display screens. The adjustment component 102 is at least partially arranged in the mounting hole 201 of the box frame 200, which is used to limit the moving direction of the locking rod 20, so that the connecting lock 101 can adapt to box frames 200 with different hole sizes.

[0039] In an optional embodiment, the adjustment component 102 includes a limit seat 1021, and the limit seat 1021 is provided with a limit through hole 10211 for the locking rod 20 to pass through. The inner diameter of the limit through hole 10211 is adapted to the outer diameter of the locking rod 20, so that after the connecting lock 101 is installed on the box frame 200 through the lock seat 10, the locking rod 20 can move along the axial direction of the limit through hole 10211, so as to better guide it to the other box frame 200 in the two adjacent LED display screens, so that the two box frames 200 can be connected together through the locking rod 20.

[0040] In an optional embodiment, the connecting lock 101 includes a locking sleeve 40, which is disposed in the lock base 10, and the locking rod 20 is threadedly connected to the locking sleeve 40. The locking sleeve 40 is movable along the height direction of the lock base 10 to limit the movement of the locking rod 20 along the locking sleeve 40, thereby enabling the splicing of two box frames 200 of different thicknesses.

[0041] For example, when the thickness of the two box frames 200 to be spliced ​​is relatively thin, the locking sleeve 40 can be controlled to move away from the mounting hole 201, thereby controlling the length of the locking rod 20 extending from the lock base 10 or the box frame 200, thereby allowing the two thinner box frames 200 to be spliced ​​together. When two thicker box frames 200 are spliced ​​together, the locking sleeve 40 can be moved toward the mounting hole 201, thereby increasing the length of the locking rod 20 extending from the lock base 10 or the box frame 200, thereby allowing the two thinner box frames 200 to be spliced ​​together. This structure is simple and easy to operate.

[0042] In an optional embodiment, a protruding portion 10212 is provided on the side of the limit seat 1021 facing the lock seat 10, and an abutting portion 41 is provided on the lock sleeve 40. The abutting portion 41 cooperates with the protruding portion 10212 to limit the axial movement length of the locking rod 20.

[0043] For example, the number of the raised portion 10212 and the abutment portion 41 is two, the two raised portions 10212 are symmetrically arranged relative to the central axis of the limit seat 1021, and the two abutment portions 41 are symmetrically arranged relative to the central axis of the lock sleeve 40. When the position of the raised portion 10212 corresponds to the position of the abutment portion 41, that is, when the raised portion 10212 abuts against the abutment portion 41, the position of the lock sleeve 40 moving toward the limit seat 1021 is limited, thereby causing the lock rod 20 to move toward the lock seat 10 or the box frame 2 00 extends outwardly at the shortest length so as to adapt to the splicing of the box frame 200 with a smaller thickness; on the contrary, when the position of the raised portion 10212 and the position of the abutment portion 41 are staggered with each other, that is, the raised portion 10212 is accommodated in the first groove between the two abutment portions 41, and the abutment portion 41 is accommodated in the second groove between the two raised portions 10212, at this time, the length of the lock rod 20 extending toward the lock seat 10 or the box frame 200 is the longest, so as to adapt to the splicing of the box frame 200 with a larger thickness.

[0044] In an optional embodiment, the adjustment assembly 102 also includes a control rod 1023, and an adjustment track 202 is provided on the box frame 200. The control rod 1023 is connected to the limit seat 1021 and is movably installed in the adjustment track 202, and is used to adjust the relative position of the raised portion 10212 in the mounting hole 201, thereby realizing the control of the extension length of the locking rod 20.

[0045] In an optional embodiment, the two ends of the adjustment rail 202 respectively have a first limit groove and a second limit groove, and the inner diameters of the first limit groove and the second limit groove are adapted to the outer diameter of the control rod 1023 to limit the position of the control rod 1023 and prevent the control rod 1023 from moving relative to the adjustment rail 202 when no force is applied.

[0046] In an optional embodiment, the connecting lock 101 includes a handle assembly 30, which is used to drive the locking rod 20 to rotate relative to the locking sleeve 40, thereby controlling the locking rod 20 to extend or retract into the lock seat 10 to achieve splicing between the two box frames 200.

[0047] In an optional embodiment, the handle assembly 30 includes a driving handle 31 and a locking wrench 32. The driving handle 31 is fixedly connected to the locking rod 20, and the locking wrench 32 is rotatably installed in the driving handle 31, and is used to cooperate with the locking sleeve 40 to limit the rotation of the driving handle 31 relative to the locking sleeve 40, thereby playing a locking role.

[0048] Illustratively, a receiving groove 311 is formed on the driving handle 31, and the locking wrench 32 is rotatably mounted in the receiving groove 311, and is used to control the coupling or decoupling of the driving handle 31 and the locking sleeve 40, so that the driving handle 31 can rotate relative to the locking sleeve 40 or be fixed to the locking sleeve 40. Specifically, the locking wrench 32 is provided with a first tooth portion 321, and the locking sleeve 40 is provided with a second tooth portion 42. The first tooth portion 321 cooperates with the second tooth portion 42 to limit the rotation of the driving handle 31 relative to the locking sleeve 40.

[0049] For example, when the first tooth portion 321 is disengaged from the second tooth portion 42, the driving handle 31 is rotated to rotate the locking rod 20 relative to the locking sleeve 40. The driving handle 31 and the locking rod 20 move axially along the locking sleeve 40, so that the locking head on the locking rod 20 can move closer to or away from the lock base 10. When the locking head approaches the lock base 10, the two box frames 200 can be locked.

[0050] In an optional embodiment, the connecting lock 101 includes an elastic component 50, which is located within the lock base 10 and is mounted on the lock sleeve 40. The two ends of the elastic component 50 respectively abut the lock base 10 and the driving handle 31. When the two box frames 200 are spliced ​​together, a thrust is applied to the driving handle 31, causing the lock head to extend into the lock hole of the other box frame 200, compressing and deforming the elastic component 50. When the two box frames 200 are disassembled, when the lock head is separated from the lock hole, the compressive deformation force of the elastic component 50 causes the lock head to disengage from the lock hole.

[0051] In an optional embodiment, the adjustment assembly 102 includes a gasket 1022, which is arranged between the lock seat 10 and the box frame 200, and is used to adjust the end face gap between the lock seat 10 and the box frame 200, so that the length of the locking rod 20 extending out of the box frame 200 is shortened, and the length of the locking rod 20 extending out of the box frame 200 can be adjusted by the thickness of the gasket 1022, which is not limited in this application.

[0052] In an optional embodiment, the adjustment assembly 102 includes an elastic member 1024, which is arranged in the mounting hole 201 and abuts against the gasket 1022 and the limit seat 1021 respectively, so that the limit seat 1021 can be firmly installed in the mounting hole 201, and it is also convenient to adjust the relative position of the protruding portion 10212 in the mounting hole 201 through the control rod 1023.

[0053] like Figures 1 to 8 As shown, according to the second aspect of the present application, the present application provides an LED display screen, including a box frame 200 and the above-mentioned connecting device 100, and the connecting lock 101 of the connecting device 100 is set in the box frame 200 for realizing splicing of adjacent box frames 200.
