Referring to fig. 1, fig. 1 shows a schematic structural diagram of a gap fine-tuning device 10 in an embodiment of the present application, and the gap fine-tuning device 10 provided in the embodiment of the present application is disposed inside a box body in a display screen, and is used for adjusting a gap between a display module and the box body in the display screen according to a user operation.

The fine gap adjustment apparatus 10 includes a base 100, a sliding member 200, and a rotating member 300. The base 100 is disposed inside the housing of the display screen and is also used to provide a foundation for the mounting and support of the components. The sliding member 200 is disposed in the sliding groove 110 of the base 100 along a first direction, and the rotating member 300 is disposed on the base 100 along a second direction intersecting the first direction and is in transmission connection with the sliding member 200. The rotating member 300 can be controlled to drive the sliding member 200 to slide along the first direction relative to the sliding groove 110, so that the sliding member 200 can apply a pushing force to the display module, and finally the gap between the display module and the box body can be adjusted.

Specifically, a sliding groove 110 is formed through both ends of the base 100 along the first direction, and the sliding member 200 is slidably disposed in the sliding groove 110 and can slide back and forth in the first direction relative to the sliding groove 110. When the sliding member 200 slides in the first direction, the end of the sliding member 200 beyond the base 100 can apply a pushing force to the display module, so as to push the display module to move and change the gap between the display module and the box body.

A rotation hole 120 is further formed in the base 100 along a second direction intersecting the first direction, one end of the rotation hole 120 is communicated with the middle point of the sliding groove 110, and the other end of the rotation hole 120 is exposed on the surface of the base 100 in an open shape.

The rotation member 300 is disposed in the rotation hole 120 and includes a positioning end 310 and an operating end 320. The positioning end 310 extends into the rotation hole 120, and the operation end 320 is exposed through the opening of the rotation hole 120 to facilitate the operation of the user. Meanwhile, the sliding member 200 is provided with a positioning hole 210, and the positioning end 310 extends into the rotating hole 120 and is in transmission connection with the positioning hole 210 of the sliding member 200.

The positioning end 310 and the operating end 320 are eccentrically disposed. When the operation end 320 is rotated by an external force, the positioning end 310 is constrained by the positioning hole 210 and converts the rotation of the rotation member 300 into the linear motion of the sliding member 200 in the first direction by abutting against the wall of the positioning hole 210.

Specifically, the positioning end 310 is a cylindrical positioning column, and the positioning end 310 is movably disposed in the positioning hole 210. The positioning hole 210 is a kidney-shaped hole formed along the third direction, and meanwhile, the dimension of the positioning hole 210 in the first direction is matched with the dimension of the positioning end 310 in the first direction, so that the positioning end 310 is ensured to be always abutted against the hole wall of the positioning hole 210 in the first direction, and when the positioning end 310 rotates along with the operating end 320, the sliding member 200 is driven to slide back along the first direction.

In one embodiment of the present invention, the base 100 is a rectangular parallelepiped, the first direction is perpendicular to a sidewall of the base 100, and the first direction, the second direction and the third direction are perpendicular to each other.

The operating end 320 is a cylindrical shaft and is at least partially received in the rotating hole 120. The handle end 320 is provided with an adjustment aperture 322 for engagement with a rotary tool to provide controlled rotation of the rotary member 300. Specifically, in the embodiment, the adjusting hole 322 is an inner hexagonal screw hole, and an operator can rotate the rotating member 300 in a clockwise direction or an anticlockwise direction by fastening the hexagonal tool to the inner hexagonal screw hole, so as to smoothly adjust the displacement of the sliding member 200.

When the rotation member 300 rotates, the position of the positioning end 310 moves in the third direction relative to the positioning hole 210 and pushes the slide member 200 to move through the positioning hole 210. Specifically, when the positioning end 310 is located at the top point or the bottom point of the positioning hole 210 along the third direction, the sliding member 200 is completely received in the sliding slot 110, and the position of the display module on the box body is not changed by the gap fine-tuning device 10. When the rotating member 300 rotates clockwise or counterclockwise, the positioning end 310 moves from the top point or the bottom point of the positioning hole 210 to the middle point of the positioning hole 210 along a third direction, i.e. descends or ascends from the top point or the bottom point of the positioning hole 210, and generates an urging force on the inner wall of the positioning hole 210, thereby pushing the sliding member 200 to move horizontally leftwards or rightwards, thereby changing the position of the display module on the box body, so as to adjust the gap between the display module and the box body.

And, when the positioning end 310 moves from the top point or the bottom point of the positioning hole 210 in the third direction to the middle point, the slider 200 slides to extend the farthest distance in the first direction relative to the base 100. At this time, the rotating member 300 is further rotated, and the positioning end 310 moves from the middle point of the positioning hole 210 to the top point or the bottom point again, so that the sliding member 200 slides along the first direction relative to the base 100 and is gradually accommodated in the base 100. The positioning end 310 can also limit the sliding member 200 to prevent the sliding member 200 from completely separating from the sliding groove 110.

In an embodiment, a part of the rotating member 300 is provided with lines through knurling, friction between the rotating member 300 and the rotating hole 120 can be increased by the lines, and the rotating member 300 is prevented from returning after being acted by an external force, so that the rotating member 300 drives the sliding member 200 to return, and the width of a gap between the display module and the box cannot be fixed.

The base 100 is further provided with a tightening hole 180, the tightening hole 180 is a cylindrical through hole, one end of the tightening hole 180 is communicated with the rotating hole 120, and the other end of the tightening hole 180 is arranged on the base 100. The fastening screw 400 is disposed in the fastening hole 180, and the fastening screw 400 abuts against the rotating member 300 to prevent the sliding member 200 from returning after receiving an external force, so that the sliding member 200 cannot fix the width of the gap between the display module and the box.

The base 100 is formed with a limiting hole 170 communicating with the sliding groove 110, and the surface of the sliding member 200 facing the limiting hole 170 is formed with a limiting groove 220. A set screw 400 is disposed in the limiting hole 170, and one end of the set screw 400 passes through the limiting hole 170 and abuts against the limiting groove 220. The distance between two groove walls of the limiting groove 220 in the first direction is the maximum sliding distance of the sliding member 200 relative to the sliding groove 110 in the first direction.

When the operation end 320 is rotated, the positioning end 310 drives the sliding member 200 to slide in the first direction, and when the fastening screw 400 abuts against the groove wall at one end of the sliding groove 110, the sliding of the sliding member 200 is stopped, so as to effectively limit the sliding stroke of the sliding member 200 and prevent the sliding member 200 from completely falling out of the sliding groove 110.

The base 100 further has a fixing hole 160. In the embodiment, the fixing hole 160 is a threaded hole, and the gap fine-tuning device 10 is screwed on the box body through the fixing hole 160.

The application also provides an LED display screen, which comprises a box body, a display module and the gap fine-tuning device 10 in the embodiment.

Specifically, the display module is movably arranged in the box body through magnet adsorption, and the gap fine-adjustment device 10 is arranged on the box body and is adjacent to the display module, so that when the rotating piece 300 rotates, the sliding piece 200 can push the display module to move, the connection between the display module and the box body can be realized, and the relative movement between the display module and the box body can be realized.

Specifically to the embodiment, the LED display screen still includes a plurality of gap micromatic setting 10, and a plurality of gap micromatic setting use the display module assembly to set up as central symmetry to make the user can adjust the clearance between display module assembly and the box omnidirectionally, thereby promote the result of use of LED display screen.

The housing has a through hole, and the rotating member 300 is aligned with the through hole of the housing so that the gap fine-adjustment device 10 can be adjusted from the through hole of the housing without disassembling the housing.
