[0035] The first aspect of the utility model is as follows Figure 1-Figure 10 As shown, a leveling connection device 1 is provided for connecting at least two display elements 100. The leveling connection device 1 comprises a connection plate 11. At least a portion of the connection plate 11 is located in the edge projection area of ​​the display element 100. The connection plate 11 is connected to the display element 100 via a connection member 12. A top member 13 is provided on the connection plate 11. The top member 13 can move along the normal direction of the display element 100 itself and abut against the display element 100 to drive the display element 100 to move.

[0036] The leveling connection device 1 includes a connection plate 11, on which are disposed a plurality of connection pieces 12 and a plurality of top pieces 13. The plurality of connection pieces 12 respectively connect the plurality of display elements 100 to the connection plate 11. The top pieces 13 on the connection plate 11 can move along the normal direction of the display element 100. The top pieces 13 abut against the display element 100 to fine-tune the display element 100, adjust the step difference between the display elements 100, and improve the flatness. The device has a small structure, low cost, and simple operation, and can improve the efficiency of leveling.

[0037] like Figure 1-Figure 4 As shown, the display system 200 includes a plurality of display elements 100 assembled and spliced ​​together, and the adjacent plurality of display elements 100 are locked and leveled by a leveling connection device 1 .

[0038] It can be understood that the connecting plate 11 is provided with connecting parts 12 corresponding to the number of display elements 100, and the number of connecting parts 12 of a leveling connection device 1 can be an integer multiple of the number of display elements 100 connected thereto, and several display elements 100 are respectively connected to the connecting plate 11 through the connecting parts 12.

[0039] It can be understood that the connecting plate 11 is provided with top pieces 13 corresponding to the number of display elements 100, and the number of top pieces 13 of a leveling connection device 1 can be an integer multiple of the number of display elements 100 connected thereto, and the distance between each display element 100 and the connecting plate 11 is adjusted by the top pieces 13 to level a plurality of display elements 100.

[0040] In one possible implementation, Figure 5 and Figure 6As shown, the connecting member 12 includes a bolt, and a through hole is opened on the connecting plate 11, and the bolt passes through the through hole.

[0041] Among them, a through hole is opened on the connecting plate 11 for the rod of the bolt to pass through, and the head of the bolt is located on the side of the connecting plate 11 away from the display element 100. The inner diameter of the through hole is larger than the rod of the bolt and smaller than the head of the bolt. During the assembly process, the tail of the bolt passes through the through hole and is connected to the display element 100, which is used to connect the connecting plate 11 and the display element 100 together.

[0042] A gasket may be installed between the head of the bolt and the connecting plate 11. The gasket is sleeved on the rod of the bolt to disperse the pressure, increase the stability of the connection, and reduce vibration and loosening.

[0043] In one possible implementation, Figure 5-Figure 10 As shown, the top member 13 includes a rod, a thread is provided on the outer wall of the rod, a head or a head can be provided at the first end of the rod, a screw groove is opened at the first end of the rod, and the second end of the rod is used to abut against the display element 100.

[0044] Among them, Figure 5 and Figure 6 As shown, the top member 13 includes a machine screw, and a first screw hole is provided on the connecting plate 11, and the machine screw is threadedly connected to the first screw hole.

[0045] The connecting plate 11 is provided with a first screw hole for the machine screw to pass through, and the machine screw can move along the normal direction of the display element 100 during the rotation in the first screw hole. During the movement of the machine screw toward the display element 100, the tail of the machine screw can abut against the display element 100, and by continuing to rotate the machine screw, the display element 100 is driven to move along the normal direction of itself, and the height difference between the multiple connected display elements 100 is adjusted, thereby improving the flatness of the assembly of the display element 100.

[0046] Among them, Figure 7-10 As shown, the head of the machine screw is provided with a torque portion 132, and the torque portion 132 can be a screw groove structure or a protrusion structure. The shape of the torque portion 132 can be a flat, cross, Pozi, plum blossom, triangle, hexagon, square, hexagon with column, H-shaped and other different structures, which can provide torque for the machine screw to rotate around its own axis.

[0047] Among them, Figure 7-10 As shown, the machine screw includes a contact surface 133, and the machine screw contacts the display element 100 through the contact surface 133. The contact surface 133 can be at least one of a plane, a conical surface, and a curved surface.

[0048] When the machine screw rotates along the first screw hole, the abutting surface 133 is used to abut against the display element 100. In order to reduce the damage of the machine screw to the display element 100, the surface of the abutting surface 133 is smooth.

[0049] Further, such as Figure 7-10 As shown, the rotational symmetry axis of the abutment surface 133 coincides with the axis of the machine screw itself. During the rotation of the machine screw, the shape of the abutment surface 133 remains unchanged relative to the display element 100, reducing the wear on the display element 100 and improving the stability of the movement of the display element 100.

[0050] In one possible implementation, Figure 5 and Figure 6 As shown, the connecting plate 11 is arranged parallel to the display element 100 , and the first screw hole is arranged along the normal direction of the display element 100 .

[0051] The connector 12 connects the connecting plate 11 and the display element 100 together. The connecting plate 11 and the display element 100 are arranged in parallel. The pressure on the connecting plate 11 is relatively even, which increases the contact area between the connecting plate 11 and the connector 12 and improves the stability of the connection.

[0052] The connecting plate 11 may be designed with rounded corners to improve safety during use.

[0053] Among them, the internal thread of the first screw hole is adapted to the external thread of the top piece 13, and the first screw hole is arranged along the normal direction of the display element 100 itself. Therefore, during the rotation of the top piece 13 in the first screw hole, it is ensured that the top piece 13 can move along the normal direction of the display element 100 itself, so that the top piece 13 abuts against the display element 100 and pushes the display element 100 to move, avoiding the top piece 13 from being displaced in the horizontal direction of the display element 100, thereby reducing the wear on the display element 100.

[0054] In one possible implementation, the number of the connecting members 12 is not less than the number of the display elements 100 , and the number of the top members 13 is not less than the number of the display elements 100 .

[0055] The number of the top pieces 13 is twice that of the connecting pieces 12 , and the top pieces 13 are disposed on both sides of the connecting piece 12 .

[0056] It is understandable that the connector 12 is used to connect the connecting board 11 and the display element 100 together, that is, at least one connector 12 is required between each display element 100 and the connecting board 11, and the number of connectors 12 is not less than the number of display elements 100.

[0057] It is understandable that the top piece 13 is used to adjust the height difference between the connecting plate 11 and the display element 100 , that is, at least one top piece 13 is required between each display element 100 and the connecting plate 11 , and the number of top pieces 13 is not less than the number of display elements 100 .

[0058] Furthermore, the number of the connecting members 12 is an integer multiple of the number of the display elements 100, the number of the top members 13 is an integer multiple of the number of the display elements 100, and the number of the top members 13 may be twice or more than the number of the connecting members 12.

[0059] The second aspect of the utility model is as follows Figure 1-Figure 10 As shown, a display system 200 is provided, comprising any one of the leveling connection devices 1 of the first aspect, the display system 200 also comprising at least two display elements 100, adjacent display elements 100 are detachably connected via the leveling connection device 1, the display element 100 comprises a box plate 110, and the connecting plate 11 is arranged parallel to the box plate 110.

[0060] It is understandable that the display system 200 is assembled from a plurality of display elements 100. Reducing the height difference between the plurality of display elements 100 can improve the overall flatness of the display system 200 and improve the display effect. The utility model connects at least two display elements 100 through a leveling connection device 1, and can fine-tune and reduce the height difference between the display elements 100.

[0061] Among them, one leveling connection device 1 can connect at least two display elements 100, the shape and number of the leveling connection device 1 are specifically set according to the shape of the display element 100, and the shape of the connection plate 11 can be set accordingly according to the shape and number of the display element 100. The shape of the display element 100 can be a triangle, a quadrilateral, a hexagon, a special shape, etc., and the number of display elements 100 connected by one leveling connection device 1 can also be three, four, five, six, or other integers.

[0062] The display element 100 includes a box plate 110 , and the height of the box plate 110 is aligned by the leveling connection device 1 .

[0063] The connection plate 11 is arranged in parallel with the box plate 110, which can improve the uniformity of the forces between the connection member 12, the top member 13, the connection plate 11 and the box plate 110, and improve the stability of the structure.

[0064] It can be understood that the connecting member 12 and the top member 13 are both arranged at the sharp corners of the box plate 110 to facilitate connecting multiple box plates 110 together through the connecting plate 11 .

[0065] like Figure 1-Figure 4As shown, in this embodiment, the shape of the display element 100 is a square as an example, the sharp corners of four adjacent display elements 100 are aligned, and the four display elements 100 are locked and leveled by a leveling connection device 1, and the connecting plate 11 can be square.

[0066] Among them, Figure 5 and Figure 6 As shown, the connecting member 12 can be set at the four corner positions of the connecting plate 11 to connect the connecting plate 11 and the box plate 110. The top member 13 can be set on both sides of the connecting member 12. The top member 13 is located between two adjacent connecting members 12. The top members 13 on both sides of a connecting member 12 are used to connect the same display element 100. The connecting member 12 is used to preliminarily fix the connecting plate 11 and the box plate 110. The top member 13 is used to adjust the distance between the connecting plate 11 and the box plate 110.

[0067] Among them, the number of connecting members 12 can be the same as the number of connected display elements 100, and the number of top members 13 can be twice the number of connected display elements 100, that is, two top members 13 are used to adjust the distance between a box plate 110 and the connecting plate 11, that is, top members 13 are provided on both sides of each connecting member 12, and a group includes a connecting member 12 and two top members 13, each group is used to connect to a box plate 110, and there are four groups in total.

[0068] In one possible implementation, Figure 5 and Figure 6 As shown, a columnar body 120 is disposed on the box plate 110 , and the columnar body 120 is disposed along the normal direction of the box plate 110 itself, and a portion of the columnar body 120 is inserted into the cavity of the connecting plate 11 .

[0069] Among them, the columnar body 120 is arranged at the sharp corner of the box plate 110, extending along the normal direction of the box plate 110 itself close to the connecting plate 11, and a cavity is provided in the middle position of the connecting plate 11, and the columnar body 120 is inserted into the cavity, and the columnar body 120 is arranged vertically to the connecting plate 11.

[0070] There may be a small clearance fit between the columnar body 120 and the connecting plate 11 .

[0071] Among them, a flange can be provided at the end of the columnar body 120, and a part of the flange is located in the edge projection area of ​​the connecting plate 11. The flange is located on the side of the connecting plate 11 away from the box plate 110, so as to limit the connecting plate 11 in the normal direction of the box plate 110 itself, thereby preventing the connecting piece 12 from loosening and causing the connecting plate 11 to fall directly off the display element 100.

[0072] It is understandable that due to the certain distance between the box plate 110 and the connecting plate 11, direct connection through the connecting piece 12 may damage the display screen. At the same time, the connecting piece 12 and the top piece 13 are too long and are easily loosened by vibration, affecting the stability of the structure.

[0073] In one possible implementation, Figure 5 and Figure 6 As shown, a connecting seat 130 protruding toward the connecting plate 11 is provided on the box plate 110, a second screw hole is opened on the connecting seat 130, and the connecting member 12 is threadedly connected to the second screw hole.

[0074] By increasing the thickness of the installation position of the connecting member 12 on the box plate 110, a connecting seat 130 protruding toward the connecting plate 11 is provided on the box plate 110. The connecting member 12 passes through the through hole and is connected to the second screw hole on the connecting seat 130. This can reduce the required length of the connecting member 12 and improve the stability of the structure.

[0075] In one possible implementation, Figure 5 and Figure 6 As shown, a mounting seat 140 protruding toward the connecting plate 11 is provided on the box plate 110 , and a groove is provided on the mounting seat 140 . A part of the top piece 13 is located in the groove, and the shape of the groove is adapted to the top piece 13 .

[0076] By increasing the thickness of the abutment position of the top piece 13 on the box plate 110, a mounting seat 140 protruding toward the connecting plate 11 is provided on the box plate 110. After the top piece 13 passes through the first screw hole, it abuts against the mounting seat 140, which can reduce the required length of the top piece 13 and improve the stability of the structure.

[0077] The top piece 13 may abut against the groove wall of the groove of the mounting seat 140 , and the side wall of the groove and the side wall of the top piece 13 may be matched with each other with a small gap.

[0078] Among them, the shape of the groove is adapted to the top piece 13, and the groove wall surface of the groove is smooth, so as to increase the contact area and fit between the groove and the top piece 13 as much as possible and reduce the friction between the two, so that when the top piece 13 moves, it can smoothly push the box plate 110 to move, fine-tune the step difference between several box plates 110, and improve the accuracy and efficiency of leveling.

[0079] Specifically, the shape of the groove is set according to the shape of the top piece 13; when the abutting surface 133 of the top piece 13 is a plane, the groove is also a matching plane; when the abutting surface 133 of the top piece 13 is a conical surface, the groove is also a matching conical surface; when the abutting surface 133 of the top piece 13 is an arc surface, the groove is also a matching arc surface.
