The gear 32 is rotatably arranged in the adjusting groove 311, and the rotation axis of the gear 32 is perpendicular to the extension direction of the adjusting groove 311. The second end of the rack 33 is inserted in the adjusting groove 311 and meshes with the gear 32. When the gear 32 rotates, the rack 33 can move along the extension direction of the adjusting sleeve 31 to adjust the angle between the first box body 10 and the second box body 20.
[0032] By applying the technical solution of the utility model, the box assembly of the LED display device includes a first box 10, a second box 20 and a first adjustment assembly 30. When adjusting the angle between the first box 10 and the second box 20, the gear 32 is rotated to move the gear 32 along the extension direction of the rack 33, and the rack 33 is moved along the extension direction of the adjustment sleeve 31. Since the first adjustment assembly 30 is located at the rear side of the LED module, the first end of the rack 33 is hinged to the first box 10, and the first end of the adjustment sleeve 31 is hinged to the second box 20. When the length of the rack 33 extending relative to the adjustment sleeve 31 increases, the distance to the rear side of the LED module increases, and the distance to the front side of the LED module remains unchanged. The first box 10 and the second box 20 are bent toward the front side of the LED module together, so that the LED module gradually forms an inner arc structure, and the curvature gradually increases. When the length of the rack 33 extending relative to the adjusting sleeve 31 decreases, the distance of the rear side of the LED module decreases, and the distance of the front side of the LED module remains unchanged. The first box 10 and the second box 20 are bent toward the rear side of the LED module, so that the LED module gradually forms an outer arc structure, and the arc gradually increases. Compared with the arc adjustment mechanism in the related art, the structure is simpler and the operation is easier.
[0033] In this embodiment, the hinge axis of the adjusting sleeve 31 and the second housing 20 , the hinge axis of the rack 33 and the first housing 10 are all parallel to the rotation axis of the gear 32 , and all extend in the vertical direction.
[0034] In other embodiments, the rotation axis of the gear 32 may extend in the horizontal direction.
[0035] It should be noted that, since the distance at the rear side of the LED module changes, the distance at the front side of the LED module remains unchanged, and thus the angle between the first box body 10 and the second box body 20 can be adjusted to bend the LED module.
[0036] like Figure 1 and Figure 3 As shown, the first adjustment assembly 30 further includes a locking member 34 movably disposed on the adjustment sleeve 31, and the locking member 34 has a locking position in which the locking member 34 is fitted with the gear 32 to stop the gear 32 from rotating, and an unlocking position separated from the gear 32. By using the locking member 34 to stop the gear 32 from rotating, the angle between the first housing 10 and the second housing 20 can be maintained unchanged, thereby keeping the curvature of the LED module unchanged.
[0037] As long as the locking member 34 can make the gear 32 stationary relative to the adjusting sleeve 31, the gear 32 can be locked. For example, the locking member 34 can be set as a plug-in column, and a plug-in slot can be set on the gear 32, and the gear 32 can be stopped by plugging the plug-in column and the plug-in slot.
[0038] like Figure 1As shown, the locking member 34 includes a knob, which is rotatably inserted into the adjusting sleeve 31 and threadedly connected to the adjusting sleeve 31, and the rotation axis of the knob is perpendicular to the rotation axis of the gear 32 and perpendicular to the extension direction of the adjusting slot 311. The locking member 34 provided with a knob can use the adjusting sleeve 31 to carry the knob, and has the advantages of simple structure and easy operation.
[0039] In this embodiment, the gear 32 is stopped from rotating by the friction force between the end of the knob and the gear 32 .

[0041] like Figures 4 to 6 As shown, there are two first adjustment components 30, and the two first adjustment components 30 are spaced apart along the length direction of the first housing 10. The two ends of the driving rod 35 are respectively inserted into the two adjustment sleeves 31 of the two first adjustment components 30, and connected to the two gears 32 of the two first adjustment components 30. By arranging two first adjustment components 30 along the length direction of the first housing 10, the angle adjustment between the first housing 10 and the second housing 20 can be made more stable, thereby making the curvature of the LED module more stable.

The adjustment prompt component 40 with the above arrangement can make different grooves 41 correspond to different curvatures of the LED module. When the protrusion 42 switches to a different groove 41, the operator is reminded that the specific angle has been switched through the sound emitted when the protrusion 42 sinks into the groove 41 and the hand feeling.
[0045] In other embodiments, a plurality of protrusions 42 may be provided on the side wall of the gear shaft, and grooves 41 may be provided in the adjusting sleeve corresponding to the protrusions 42 .
[0046] Of course, a plurality of prompt lines may be provided on the side wall of the adjustment sleeve 31 , and prompt points may be provided on the gear shaft. When the prompt points and the prompt lines are aligned, the curvature of the LED module at this time is determined.
