[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 6 As shown, the present application provides an LED spherical box assembly including: a plurality of frames 10, a connecting piece 20 and a wedge 30. The plurality of frames 10 are spliced ​​in sequence so that the inner surfaces of the plurality of frames 10 are connected together to form an inner spherical surface, and the plurality of frames 10 at least include a first frame 11 and a second frame 12 that are spliced. The connecting piece 20 is connected to the outer surfaces of the first frame 11 and the second frame 12, and blocks the first splicing seam 13 between the first frame 11 and the second frame 12. The wedge 30 is adjustably arranged in the first splicing seam 13 along the radial position of the inner spherical surface and is connected to the connecting piece 20.

[0032] By applying the technical solution of this embodiment, the connecting piece 20 is connected to the outer surface of the first frame 11 and the second frame 12, and blocks the first joint 13 between the first frame 11 and the second frame 12, so that the first frame 11 and the second frame 12 can be spliced ​​together. The wedge block 30 is adjustably arranged in the first joint 13 along the radial position of the inner spherical surface. Along the radial direction of the inner spherical surface, the wedge block 30 can adjust the size of the first joint 13 between the first frame 11 and the second frame 12, avoiding the method of relying on moving only one of the frames 10 for adjustment, and can meet the precision requirements of splicing multiple frames 10 together. In this way, the technical solution of this embodiment can solve the problem in the related art that the precision requirements of splicing multiple unit board brackets together cannot be met.

[0033] Furthermore, the present application has multiple connecting pieces, and multiple connecting pieces and multiple frames 10 are sequentially spliced ​​together to achieve quick installation without relying on an external skeleton for support, making installation easier.

[0034] like Figures 1 to 6 As shown, in order to facilitate the radial position adjustment of the wedge block 30 along the inner spherical surface, the LED spherical box assembly also includes an adjustment member 40 passing through the connecting piece 20 and the wedge block 30. When the adjustment member 40 rotates, it drives the wedge block 30 to adjust its position along the radial direction of the inner spherical surface.

[0035] like Figures 1 to 6 As shown, the adjusting member 40 includes a threaded rod 41, and a screw hole 42 is provided on the wedge block 30 to cooperate with the threaded rod 41, and the axis of the screw hole 42 extends along the radial direction of the inner spherical surface. Since the rotation of the wedge block 30 itself is restricted by the first frame 11 and the second frame 12, the wedge block 30 can only move along the radial direction of the inner spherical surface. In this way, when the threaded rod 41 rotates, the spiral cooperation between the screw hole 42 and the threaded rod 41 converts the rotation of the threaded rod 41 into the linear movement of the wedge block 30, so that the position of the wedge block 30 is adjusted along the radial direction of the inner spherical surface.

[0036] like Figures 1 to 6As shown, the multiple frames 10 also include a third frame 17 and a fourth frame 18 that are spliced ​​with each other. The third frame 17 is spliced ​​with the second frame 12, and the fourth frame 18 is spliced ​​with the first frame 11. A second splicing seam 14 connected to the first splicing seam 13 is formed between the second frame 12 and the third frame 17, a third splicing seam 15 connected to the first splicing seam 13 is formed between the third frame 17 and the fourth frame 18, and a fourth splicing seam 16 connected to the first splicing seam 13 is formed between the fourth frame 18 and the first frame 11. A cross-shaped splicing seam is formed at the place where the first splicing seam 13, the second splicing seam 14, the third splicing seam 15 and the fourth splicing seam 16 are connected to each other. The connecting piece 20 is connected to the outer surfaces of the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18, and blocks the cross-shaped splicing seam. The wedge block 30 is adjustably arranged in the first splicing seam 13 along the radial position of the inner sphere. In this way, one connecting piece 20 can simultaneously connect the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18, so as to facilitate splicing the four frames 10 together. When the radial position of the wedge 30 along the inner spherical surface is adjusted, the size of the second splicing seam 14, the third splicing seam 15 and the fourth splicing seam 16 can be referred to for real-time adjustment.

[0037] Specifically, in order to flexibly meet the precision requirements of splicing multiple frames 10 together, there are four wedge blocks 30, which are respectively arranged in the first splicing seam 13, the second splicing seam 14, the third splicing seam 15 and the fourth splicing seam 16. Correspondingly, there are four adjusting members 40, which are respectively arranged on the four wedge blocks 30.

[0038] like Figures 1 to 6 As shown, in order to connect the connecting piece 20 to the outer surfaces of the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18, the LED spherical box assembly also includes four first fasteners 51, and the four first fasteners 51 are connected to the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18 one by one to connect the connecting piece 20 to the outer surfaces of the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18.

[0039] like Figures 1 to 6As shown, the connecting sheet 20 is provided with four first strip holes 21 for four first fasteners 51 to pass through, and each first strip hole 21 extends from the center of the connecting sheet 20 to a corner of the connecting sheet 20. In this way, before the wedge block 30 adjusts the size of the first joint seam 13 along the radial position of the inner sphere, the first fasteners 51 on the first frame 11 and the second frame 12 can be loosened, and the first fasteners 51 on the first frame 11 or the second frame 12 move relative to the first strip holes 21, so that the wedge block 30 can subsequently adjust the size of the first joint seam 13 along the radial position of the inner sphere. After the size of the first joint seam 13 meets the precision requirement for splicing the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18 together, the first fasteners 51 are tightened to fix the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18.

[0040] like Figures 1 to 6 As shown, in order to improve the reliability of the first frame 11 and the second frame 12 being spliced ​​together, the first frame 11 includes a first side panel 111 adjacent to the second frame 12, the second frame 12 includes a second side panel 121 adjacent to the first frame 11, and the LED spherical box assembly further includes a second fastener 52 connecting the first side panel 111 and the second side panel 121. Before the wedge block 30 adjusts the size of the first splicing seam 13 along the radial position of the inner spherical surface, the second fastener 52 can be loosened to facilitate the subsequent wedge block 30 to adjust the size of the first splicing seam 13 along the radial position of the inner spherical surface.

[0041] like Figures 1 to 6 As shown, the wedge block 30 is located between the first side plate 111 and the second side plate 121, and a second strip hole 31 is provided on the wedge block 30 for the second fastener 52 to pass through. In the process of adjusting the size of the first joint seam 13 along the radial position of the inner spherical surface, the second fastener 52 can be loosened, and the second fastener 52 moves relative to the second strip hole 31. After the size of the first joint seam 13 meets the precision requirement for splicing the first frame 11, the second frame 12, the third frame 17 and the fourth frame 18 together, the second fastener 52 is fastened to fix the first frame 11 and the second frame 12.

[0042] like Figures 1 to 6 As shown, in the process of adjusting the size of the first joint seam 13 along the radial position of the inner spherical surface by the wedge 30, in order to prevent the adjustment member 40 from interfering with the connecting piece 20, a third strip hole 22 for the adjustment member 40 to pass through is provided on the connecting piece 20, and the extension direction of the third strip hole 22 itself is consistent with the extension direction of the first joint seam 13 along the circumferential direction of the inner spherical surface. In order to make the connecting piece 20 adapt to the outer surface of the first frame 11 and the second frame 12 and ensure the stability of the connection, the side of the connecting piece 20 that contacts the outer surface of the first frame 11 and the second frame 12 is a contact spherical surface.

[0043] The present application also provides an LED spherical display device, which includes an LED spherical box assembly and a plurality of display modules 60. The LED spherical box assembly is the above-mentioned LED spherical box assembly, and the plurality of display modules 60 are connected one by one to the inner surfaces of the plurality of frames 10 of the LED spherical box assembly. Since the above-mentioned LED spherical box assembly can solve the problem in the related art that the precision requirements of splicing together of a plurality of unit board brackets cannot be met, the LED spherical display device having the LED spherical box assembly can solve the same technical problem. The plurality of display modules 60 can be spliced ​​into an inner spherical display surface, providing an experience space for panoramic display and satisfying the depth experience of 3D integration. Of course, in an embodiment not shown in the figure, the plurality of display modules are connected to the inner surface of a frame of the LED spherical box assembly.
