[0030] The embodiments of the utility model provide a splicing mechanism and a splicing screen. The following are detailed descriptions. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] See also Figure 1-5 The present invention provides a splicing mechanism 1 for splicing display screens. The splicing mechanism 1 includes at least two splicing units 10 spliced ​​to each other, and each of the splicing units 10 includes a plurality of side surfaces.

[0032] The multiple side surfaces include a first side surface 10a, a second side surface 10b, a third side surface 10c and a fourth side surface 10d connected end to end, the first side surface 10a is arranged opposite to the third side surface 10c, and the second side surface 10b is arranged opposite to the fourth side surface 10d. The first side surface 10a and the second side surface 10b are both provided with at least one ball screw 11 and at least one gap adjustment member 12, the third side surface 10c is provided with at least one positioning groove 13 corresponding to the ball screw 11 on the first side surface 10a, and the fourth side surface 10d is provided with at least one positioning groove 13 corresponding to the ball screw 11 on the second side surface 10b.

[0033] The ball screw 11 in the utility model cooperates with the positioning groove 13 to support and position the two adjacent splicing monomers 10. When the ball screw 11 is assembled, there is a gap between the two adjacent splicing monomers 10 in the initial state. Due to the elasticity of the ball screw 11, it can be compressed, so the gap between the two splicing monomers 10 can be adjusted by adjusting the gap adjustment member 12 until it is adjusted to zero gap, thereby achieving zero gap splicing.

[0034] It should be noted that, for two splicing monomers 10 arranged up and down and spliced ​​to each other, the third side surface 10c of the splicing monomer 10 located at the top is connected to the first side surface 10a of the splicing monomer 10 located at the bottom; wherein the first side surface 10a of the splicing monomer 10 located at the bottom is provided with the ball screw 11, and the third side surface 10c of the splicing monomer 10 located at the top is correspondingly provided with the positioning groove 13. For two splicing monomers 10 arranged left and right and spliced ​​to each other, the second side surface 10b of the splicing monomer 10 located on the left is connected to the fourth side surface 10d of the splicing monomer 10 located on the right; wherein the second side surface 10b of the splicing monomer 10 located on the left is provided with the ball screw 11, and the fourth side surface 10d of the splicing monomer 10 located on the right is correspondingly provided with the positioning groove 13.

[0035] The splicing process of two adjacent splicing monomers 10 is described as follows: first, the corresponding side surfaces of the two splicing monomers 10 are aligned so that the ball screw 11 is aligned with the corresponding positioning groove 13, and the ball screw 11 is assembled in the corresponding positioning groove 13 to support and position the two splicing monomers 10. At this time, there is a certain gap between the two adjacent splicing monomers 10; then, the gap adjustment member 12 is assembled on the side surface of the splicing monomer 10, and the tightness of the gap adjustment member 12 is controlled to compress the ball screw 11, so that the gap between the two adjacent splicing monomers 10 is continuously reduced until it is adjusted to zero gap, thereby achieving zero gap splicing.

[0036] In the embodiment of the utility model, for the convenience of splicing, the plane shape of the splicing monomer 10 is a quadrilateral, and optionally, the plane shape of the splicing monomer 10 is a rectangle. Of course, in other embodiments, the plane shape of the splicing monomer 10 can also be other polygons or special shapes, and the utility model does not limit this.

[0037] In one embodiment, if Figure 5 As shown, the ball screw 11 includes a base 110, an elastic member 111 and a ball 112, one end of the elastic member 111 is connected to the base 110, and the other end is connected to the ball 112. The ball 112 of the ball screw 11 in one splicing unit 10 cooperates with the corresponding positioning groove 13 in another adjacent splicing unit 10.

[0038] Specifically, the ball 112 is disposed on the top surface of the ball screw 11, and the spherical surface of the ball 112 is exposed to the outside. The ball 112 corresponds to the positioning groove 13 one by one, and when the ball screw 11 is assembled, at least part of the ball 112 is located in the positioning groove 13.

[0039] The elastic member 111 can be compressed and stretched under force. When the gap between two adjacent splicing units 10 is adjusted by the gap adjustment member 12 , the elastic member 111 of the ball screw 11 is compressed under force.

[0040] Optionally, the elastic member 111 may include a spring or the like.

[0041] Optionally, the shape of the positioning groove 13 is the same as the spherical shape of the ball 112 .

[0042] In the embodiment of the utility model, the first side surface 10a and the second side surface 10b are provided with a first adjustment hole 14, the third side surface 10c and the fourth side surface 10d are provided with a second adjustment hole 15, and the second adjustment hole 15 is provided corresponding to the first adjustment hole 14. The gap adjustment member 12 cooperates with the first adjustment hole 14 in one of the splicing monomers 10 and the corresponding second adjustment hole 15 in another adjacent splicing monomer 10.

[0043] In this way, when the gap adjustment member 12 is used to adjust the gap between two adjacent splicing monomers 10, the gap adjustment member 12 can be controlled to move up and down in the first adjustment hole 14 and the second adjustment hole 15. For example, taking the two splicing monomers 10 spliced ​​up and down as an example, when the gap adjustment member 12 is controlled to move downward in the first adjustment hole 14 and the second adjustment hole 15, the two splicing monomers 10 are constantly approaching each other, so that the ball screw 11 is compressed, so that the gap between the two adjacent splicing monomers 10 is continuously reduced until it is adjusted to zero gap, thereby achieving zero gap splicing.

[0044] Optionally, the gap adjustment member 12 includes a gap screw, etc., and the gap screw includes a matching bolt 122 and a nut 121, the bolt 122 is located in the first adjustment hole 14 and the second adjustment hole 15, and the nut 121 is located on the side of the splicing mechanism 1. Optionally, the nut 121 can be rotated by a wrench to make the bolt 122 move up and down in the first adjustment hole 14 and the second adjustment hole 15.

[0045] In the embodiment of the present utility model, Figure 2-3As shown, each of the splicing units 10 includes a main board 16 and a plurality of fixing parts 17 on the main board 16, each of the fixing parts 17 being arranged at the connection between two adjacent side surfaces; wherein the ball screws 11 and the gap adjusting member 12 are arranged on the fixing parts 17. That is, the fixing parts 17 are located at the four corners of the main board 16, and can prevent other components on the main board 16 from bumping while playing the role of arranging the ball screws 11 and the gap adjusting member 12.

[0046] Specifically, the plane shape of the main board 16 is the same as the plane shape of the splicing unit 10 . In the embodiment of the utility model, the plane shape of the main board 16 is a rectangle.

[0047] In one embodiment, the fixing portion 17 can be integrally formed with the main board 16, which is beneficial to improving the strength of the fixing portion 17; in another embodiment, the fixing portion 17 and the main board 16 can also be made separately, and the two can be fixedly connected by mechanical means to facilitate replacement and maintenance.

[0048] Specifically, Figure 4 As shown, each of the fixing parts 17 includes an inner side surface connected between two adjacent side surfaces, and the inner side surface is composed of a plurality of steps 171; wherein the gap adjusting member 12 is arranged corresponding to the steps 171 located at the edge, and the ball screw 11 is arranged corresponding to the steps 171 located at the middle area. In this way, the inner side surface of the fixing part 17 is stepped, that is, the thickness of the part of the fixing part 17 where the ball screw 11 is arranged is greater than the thickness of the part of the fixing part 17 where the gap adjusting member 12 is arranged, so as to facilitate the placement and locking of the gap adjusting member 12.

[0049] Specifically, the surface of the area where the ball screw 11 is set on the first side surface 10a and the second side surface 10b is higher than the surface of the area where the gap adjustment member 12 is set, so that in the splicing process of two adjacent splicing monomers 10, the gap between the two corresponding sides of the two splicing monomers 10 at the gap adjustment member 12 is greater than the gap at the ball screw 11, so that the gap adjustment member 12 has a larger gap adjustment margin.

[0050] In one embodiment, in order to ensure that the splicing unit 10 has enough positioning points during splicing without causing assembly difficulties due to too many positioning points, two ball screws 11 and two gap adjustment members 12 are provided on the first side 10a and the second side 10b. Of course, in other embodiments, multiple ball screws 11 and multiple gap adjustment members 12 are provided on the first side 10a and the second side 10b, and the utility model does not limit the number of the ball screws 11 and the gap adjustment members 12.

[0051] In an embodiment of the utility model, at least one hook 18 is provided on the main board 16, and the splicing screen also includes at least one hanger 19, each of the hangers 19 at least spans across two of the splicing units 10 and is fixedly connected to the hook 18 to achieve a fixed connection between two adjacent splicing units 10.

[0052] In the embodiment of the utility model, a plurality of driving circuit boards 20 are further arranged on the main board 16, and the hook 18 is arranged in the interval area of ​​the plurality of driving circuit boards 20, and the driving circuit board 20 is used to provide a driving signal to the display screen 2. The driving circuit board 20 is arranged on the main board 16, which is conducive to realizing a narrow frame, thereby further realizing zero gap splicing.

[0053] Accordingly, see Figure 6 The embodiment of the utility model further provides a splicing screen. The splicing screen comprises the splicing mechanism 1 in the above embodiment and at least two display screens 2, the splicing mechanism 1 is arranged on the non-light-emitting side of the display screen 2, and the display screens 2 are spliced ​​by the splicing structure.

[0054] In the embodiment of the utility model, one splicing unit 10 may correspond to one display screen 2 , that is, each display screen 2 is located on a corresponding splicing unit 10 .

[0055] Specifically, the display screen 2 may be a liquid crystal display screen 2 or an organic light emitting diode display screen 2, and the present invention does not limit this. Since the above embodiment has described the splicing mechanism 1 in detail, the splicing mechanism 1 will not be described in detail in the embodiment of the present invention.

[0056] Beneficial effect: In the splicing mechanism and splicing screen provided by the embodiment of the utility model, the splicing mechanism includes at least two splicing units spliced ​​to each other, at least one ball screw and at least one gap adjustment member are provided on the first side and the second side of the splicing mechanism, at least one positioning groove corresponding to the ball screw on the first side is provided on the third side, and at least one positioning groove corresponding to the ball screw on the second side is provided on the fourth side. The ball screw in the utility model cooperates with the positioning groove to position and support the splicing unit. At this time, there is a gap between the two adjacent splicing units in the initial state. Due to the elasticity of the ball screw itself, it can be compressed, so the gap between the two splicing units can be adjusted by the gap adjustment member until it is adjusted to zero gap, thereby achieving zero gap splicing.
