[0030] Example 1

[0031] Combination Figures 1 to 3 As shown, the splicing device for the display unit of this utility model is schematically illustrated. It is suitable for splicing the cabinet 40 of the display unit and includes a connecting plate 10 and multiple connecting components.

[0032] like Figure 3 The connecting plate 10 has multiple mounting holes 11. In this embodiment, the connecting plate 10 is rectangular and has four mounting holes 11 with circular cross-sections. The four mounting holes 11 are arranged in a matrix. Correspondingly, the number of connecting components is four, that is, the number of connecting components is the same as the number of mounting holes 11.

[0033] The connecting assembly includes a connecting rod 20 and an eccentric block 30. Each connecting rod 20 corresponds to a mounting hole 11. The connecting rod 20 can slide through the mounting hole 11. The connecting rod 20 is also used to pass through the connecting hole 41 of the box 40. Each box 40 has several connecting holes 41 at its corners. Therefore, the connecting plate 10 can be connected to the four boxes 40 through the connecting assembly to realize the positioning and splicing of the four boxes 40.

[0034] The connecting rod 20 has a head end 21 and a tail end 22. An eccentric block 30 is rotatably connected to the head end 21 of the connecting rod 20, and the tail end 22 of the connecting rod 20 is engaged with the opening of the connecting hole 41. The circumferential surface 321 of the eccentric block 30 abuts against the connecting plate 10. This allows the eccentric block 30 and the tail end 22 of the connecting rod 20 to abut against two opposite surfaces of the housing 40, thus clamping the housing 40 with the connecting assembly. Rotating the eccentric block 30 allows its circumferential surface 321 to abut against or move away from the connecting plate 10, thereby clamping or releasing the housing 40. Installation and maintenance personnel only need to rotate the eccentric block 30 to clamp or release the housing 40, improving the efficiency of connecting or disassembling the splicing screen and enabling tool-free assembly and disassembly of the splicing screen.

[0035] The tail end 22 of the connecting rod 20 is provided with a limiting ring 221. The cross-sectional area of ​​the limiting ring 221 is larger than that of the connecting rod 20. The end face of the limiting ring 221 is engaged with the opening of the connecting hole 41. The limiting ring 221 can prevent the connecting rod 20 from passing through the connecting hole 41 from its tail end 22 to its head end 21, thus achieving the engagement between the tail end 22 of the connecting rod 20 and the opening of the connecting hole 41. The connecting rod 20 is a cylinder, and the cross-sectional shape of the connecting hole 41 is circular. The limiting ring 221 is preferably annular, which is beneficial for the machining of the connecting rod 20.

[0036] Among them, a buffer 23 is provided between the end face of the limiting ring 221 and the opening of the connecting hole 41. The buffer 23 can not only provide a certain buffer margin for the abutting connection between the connecting component and the housing 40, so as to prevent the eccentric block 30 from getting stuck with the connecting plate 10 before the eccentric block 30 has rotated into place, but the buffer 23 can also solve the problem of machining accuracy deviation of the connecting rod 20 and the connecting hole 41.

[0037] Furthermore, the housing 40 is provided with a receiving cavity 42, and a connecting hole 41 is provided on the bottom surface of the receiving cavity 42. The bottom surface of the receiving cavity 42 is circular. The limiting ring 221 is located inside the receiving cavity 42, and the end face of the limiting ring 221 abuts against the bottom surface of the receiving cavity 42. The receiving cavity 42 can be used to receive the limiting ring 221 to prevent the limiting ring 221 from interfering with other components inside the housing 40. At the same time, the setting of the receiving cavity 42 can prevent maintenance personnel from inserting other parts resembling the connecting rod 20 into the connecting hole 41, which has a foolproof function.

[0038] The connecting plate 10 is provided with a gasket 12 made of polyoxymethylene material. The peripheral surface 321 of the eccentric block 30 abuts against the gasket 12. The gasket 12 can reduce the friction between itself and the peripheral surface 321 of the eccentric block 30, so that the peripheral surface 321 of the eccentric block 30 and the gasket 12 can slide more smoothly relative to each other. This is beneficial for installation and maintenance personnel to rotate the eccentric block 30 with less force, and improves the disassembly and assembly experience of the splicing screen.

[0039] In this embodiment, a handle 34 is provided on the eccentric block 30 to facilitate the rotation of the eccentric block 30 by the installation and maintenance personnel.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that, in combination with Figure 3 As shown, the first end 21 of the connecting rod 20 is provided with a connecting groove 211. The opening of the connecting groove 211 is located on the outer side wall of the connecting rod 20. The extension direction of the connecting groove 211 is inclined or perpendicular to the extension direction of the connecting rod 20. The eccentric block 30 is provided with a rotating shaft 33. The rotating shaft 33 is detachably snapped into the connecting groove 211, and the rotating shaft 33 and the connecting groove 211 are rotatably connected. This allows the eccentric block 30 to be installed or disassembled with the connecting rod 20. When assembling the box 40, the installation and maintenance personnel first pass the connecting rod 20 through the connecting hole 41 of the box 40, and then connect the eccentric block 30 to the first end 21 of the connecting rod 20 through the rotating shaft 33 and the connecting groove 211, so as to realize the quick assembly and disassembly of the connecting components. The extension direction of the connecting groove 211 is inclined to the extension direction of the connecting rod 20. When the rotating shaft 33 is engaged in the connecting groove 211 and the circumferential surface 321 of the eccentric block 30 abuts against the gasket 12, the extension direction of the connecting groove 211 is set so that the rotating shaft 33 can be stably engaged in the connecting groove 211 without slipping out of the connecting groove 211.

[0042] Furthermore, the eccentric block 30 is provided with a cam 32, the cam 32 having the aforementioned circumferential surface 321, the eccentric block 30 having a relief plane 31, one end of the circumferential surface 321 being connected to one end of the relief plane 31, the distance between the circumferential surface 321 and the rotation axis of the eccentric block 30 being greater than the distance between the relief plane 31 and the rotation axis of the eccentric block 30, during the forward rotation of the eccentric block 30, the relief plane 31 is initially positioned opposite to the connecting plate 10, at which point the connecting rod 20 can still slide relative to the connecting hole 41, as the eccentric block 30 continues to rotate forward, the relief plane 31 opposite to the connecting plate 10 is switched to the circumferential surface 321 of the cam 32, the circumferential surface 321 being slidably abutting against the connecting plate 10, and realizing the clamping of the housing 40 by the cam 32 and the limiting ring 221.

[0043] Example 3

[0044] like Figure 1This embodiment provides a display device, including multiple display units and a splicing device for the display units. Each display unit includes a cabinet 40 and several display modules. The several display modules are disposed on the cabinet 40. The splicing device for each display unit is connected to four cabinets 40, so as to realize the splicing of multiple display units and finally form a splicing screen with a larger display area.

[0045] In summary, the connecting rods 20 of each connecting component are respectively inserted through the mounting holes 11 of the connecting plate 10. The tail end 22 of the connecting rod 20 is engaged with the opening of the connecting hole 41 of the housing 40. The head end 21 of the connecting rod 20 is rotatably connected to the eccentric block 30. The circumferential surface 321 of the eccentric block 30 slidably abuts against the connecting plate 10. The eccentric block 30 restricts the position of the connecting plate 10, so that the connecting plate 10 and the tail end 22 of the connecting rod 20 can clamp the housing 40. The connecting plate 10 is connected to multiple connecting components to clamp multiple housings 40, realizing the splicing of multiple housings 40. Rotating the eccentric block 30 can tighten or release the connecting plate 10, thereby realizing the quick locking or release of the housing 40 by the connecting components, saving a lot of manpower and time.
