[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Example 1

[0034] Combine Figures 1 to 6 As shown, the display unit connection device of the present invention is schematically shown, comprising a base 10 and a connecting component 20. The base 10 is used to provide a mounting base for the connecting component 20. The end of the connecting component 20 is provided with a connecting structure for connecting to the housing of the display unit, that is, the connecting structure can be connected to the housing of another display unit. The connecting component 20 is slidably connected to the base 10. Preferably, the connecting component 20 is slidably connected to the base 10 along a preset direction A, that is, the connecting component 20 and the base 10 can slide back and forth relative to each other in the preset direction A. When the base 10 has a receiving space 14, a portion of the connecting component 20 is accommodated in the receiving space 14. The sliding connection between the connecting component 20 and the base 10 allows the connecting component 20 to extend from the receiving space 14 to the outside of the base 10, or to be retracted and accommodated in the receiving space 14.

[0035] like Figure 4 The base 10 is movably provided with a limiting component 30. The limiting component 30 and the base 10 can be connected in a sliding manner or in a rotating manner. The movement trajectory of the connecting component 20 intersects with the movement trajectory of the limiting component 30. Therefore, the limiting component 30 can prevent the connecting component 20 from sliding relative to the base 10 under certain conditions. Specifically, the limiting component 30 has a locked state and an unlocked state. When the limiting component 30 is in the locked state, the limiting component 30 is engaged with the connecting component 20, so that the connecting component 20 cannot slide relative to the base 10 in the above-mentioned preset direction A. When the limiting component 30 is in the unlocked state, the limiting component 30 and the connecting component 20 are slidably abutted. At this time, the connecting component 20 can slide relative to the base 10 in the above-mentioned preset direction A. At the same time, the limiting component 30 and the connecting component 20 are slidably connected, and the limiting component 30 does not restrict the connecting component 20 from sliding relative to the base 10.

[0036] Further, combined with Figure 4 and Figure 5 The connecting member 20 is provided with a limit block 21. The limit block 21 is arranged along the sliding direction between the connecting member 20 and the base 10 (i.e., the preset direction A). The limit block 21 has a head end 21a and a tail end 21b. The tail end 21b of the limit block 21 is fixedly connected to the connecting member 20. The limit block 21 is provided with a limit inclined surface 211 that is arranged at an angle relative to the motion trajectory of the connecting member 20. That is, the inclination direction of the limit inclined surface 211 is arranged from the head end 21a to the tail end 21b of the limit block 21. When the limit member 30 is in the unlocked state, it can slidably abut against the limit inclined surface 211. When the limit member 30 is in the locked state, it is engaged with the head end 21a of the limit block 21.

[0037] When the limiting component 30 is in the unlocked state, Figure 2 and Figure 3When the movement direction of the connecting component 20 is from the tail end 21b of the limiting block 21 to the head end 21a, the connecting component 20 is gradually accommodated in the accommodating space 14, and the limiting component 30 moves toward the direction of approaching the connecting component 20 under the guidance of the limiting slope 211. When the movement direction of the connecting component 20 is from the head end 21a of the limiting block 21 to the tail end 21b, the connecting component 20 extends out of the accommodating space 14, and the limiting component 30 moves toward the direction of moving away from the connecting component 20 under the guidance of the limiting slope 211. Figure 1 and Figure 2 When the connecting component 20 continues to move in this direction, the limiting component 30 passes the edge of the limiting slope 211, and the limiting component 30 disengages from the limiting slope 211. If the limiting component 30 moves in the direction close to the connecting component 20, the limiting component 30 abuts against the head end 21a of the limiting block 21, so that the limiting component 30 switches to the locked state.

[0038] In order to automatically switch to the locked state after the limiting component 30 disengages from the limiting slope 211, the display unit connecting device also includes an elastic member (not shown in the figure), the two ends of the elastic member are respectively connected to the base 10 and the limiting component 30, and the limiting component 30 has a tendency to move toward the connecting component 20 under the elastic force of the elastic member. Therefore, when the limiting component 30 passes over the edge of the limiting slope 211, the limiting component 30 disengages from the limiting slope 211, and the limiting component 30 moves in the direction close to the connecting component 20 under the elastic force of the elastic member. The limiting component 30 abuts against the head end 21a of the limiting block 21, so that the limiting component 30 switches from the unlocked state to the locked state.

[0039] Furthermore, the display unit connection device also includes a guide assembly, which includes a slide groove 22 and a slider 11 that are slidably engaged with each other. The slide groove 22 is provided on the connecting component 20, and the slider 11 is provided on the base 10. The provision of the slide groove 22 and the slider 11 is used to limit the degrees of freedom between the connecting component 20 and the base 10, so that the connecting component 20 and the base 10 can slide back and forth in the preset direction A. In this embodiment, the slide groove 22 and the limit block 21 are provided in parallel to reduce the structural length of the connecting component 20 in the above-mentioned preset direction A, making the structure of the connecting component 20 more compact. In addition, the base 10 is provided with a guide block 12 located on one side of the motion trajectory of the connecting component 20. The side edge of the connecting component 20 can slidably abut the guide block 12. The guide block 12 is also used to limit the degrees of freedom between the connecting component 20 and the base 10. The guide block 12 and the slide groove 22 are respectively located on both sides of the limit block 21.

[0040] Combine Figure 4 and Figure 6As shown, the limiting component 30 includes a limiting rod 31, and the base 10 is provided with a mounting hole 32. The limiting rod 31 can be slidably penetrated into the mounting hole 32, wherein the end of the limiting rod 31 is clamped to the connecting component 20 in the locked state, and the end of the limiting rod 31 can slidably abut against the connecting component 20 in the unlocked state. A pull block 311 is also provided at the end of the limiting rod 31 away from the connecting component 20. The installation and maintenance personnel can apply force to the pull block 311 to pull the limiting rod 31 to move the limiting rod 31 away from the connecting component 20 (at this time, the elastic potential energy of the elastic member increases), and switch the limiting component 30 from the locked state to the unlocked state.

[0041] Example 2

[0042] The difference between this embodiment and the first embodiment is that the connection structure includes a connection through hole 23 provided in the connection component 20 , and the connection through hole 23 can be connected to a rod-shaped structure on another display unit housing.

[0043] Example 3

[0044] This embodiment differs from Example 1 in that the connection structure includes a hook 24 located on the side of the connection component 20. The hook 24 can connect to a hole or slot on another display unit housing. In some optional embodiments, the connection structure includes the hook 24 of this embodiment and the connecting hole 23 of Example 2, with the hook 24 and the connecting hole 23 located at opposite ends of the connection component 20.

[0045] In addition, the base 10 is provided with a connecting member 13 , which abuts against the hook 24 when the limiting member 30 is in a locked state. The connecting member 13 can limit the travel limit of the connecting member 20 through the hook 24 .

[0046] Example 4

[0047] This embodiment provides a display device, including a display unit and the display unit connecting device as described above. The display unit housing is provided with a base 10. The base 10 can be assembled and connected to the housing, or can be designed as an integral whole with the housing. The connecting component 20 of the display unit connecting device is used to connect to the housings of other display units.

[0048] To sum up, the connecting component 20 can be connected to the box of other display units through the connecting structure at its end. The connecting component 20 and the base 10 can be slidably connected, so that the connecting component 20 has a storage function. The limiting component 30 movably connected to the base 10 can lock the movement of the connecting component 20 so that the connecting component 20 can be stably maintained in the extended state and connected to the box of other display units. After the limiting component 30 is switched from the locked state to the unlocked state, the connecting component 20 can slide and be stored relative to the base 10, saving space and avoiding damage caused by collision with foreign objects.
