Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] In order to solve the problems existing in the current LED cabinet connection device in terms of versatility, installation efficiency and convenience. Figures 1 to 3 As shown, the present application provides a universal, easy-to-install, and highly efficient LED box connection device, which includes a connection base 1, a cushion block 2, a first fastener 4, and a second fastener 5.

[0045] The connection base 1 is the core skeleton of the entire connection device, and is provided with a first connection hole 11 and a second connection hole 12. The number of the second connection holes 12 is at least two, and the number can be flexibly selected according to actual needs, such as two, three or four, to meet the connection requirements of display cabinets of different specifications and quantities, which not only ensures the applicability of the connection device, but also improves the installation flexibility.

[0046] One side of the cushion block 2 is connected to the connection base 1, and the other side is used to directly contact the display box. In order to allow the second fastener 5 to pass through the cushion block 2 and connect to the display box, the cushion block 2 is provided with a third connection hole 21 corresponding to the second connection hole 12.

[0047] The first fastener 4 is used to connect the connection base 1 to the mounting frame. Specifically, the first fastener 4 is designed as a bolt, and the first connection hole 11 is a threaded hole on the connection base 1. When in use, the first fastener 4 only needs to be inserted through the first connection hole 11 and threadedly connected or abutted with the mounting frame. By adjusting the extension length of the first fastener 4, it can be compatible with the installation of various mounting frames, thereby increasing its scope of application.

[0048] The second fastener 5 is an important component for connecting the connection base 1 to the display box. The second fastener 5 can be movably arranged in the second connection hole 12 and the third connection hole 21. By adjusting the specific position of the second fastener 5, it can adapt to the connection requirements of display boxes of different specifications, without the need to design and produce a special connection device, which not only improves the versatility of the connection device, but also reduces the production cost. The second fastener 5 can be specifically a captive bolt, also called a captive bolt. The captive bolt will not fall off from the second connection hole 12 and the third connection hole 21 when it is not tightened on the display box. The number of second fasteners 5 matches the number of second connection holes 12, and an appropriate number can be selected according to actual needs, such as two, three or four, etc., to meet the connection requirements in different scenarios. Among these second fasteners 5, at least one can be connected to other display boxes, thereby achieving a stable connection between two or more display boxes.

[0049] like Figures 1 to 3 As shown, in one embodiment of the present application, the connecting base 1 includes a groove portion 13 and flange portions 14 arranged on both sides of the groove portion 13 and extending in the transverse direction, the first connecting hole 11 is arranged in the groove portion 13, and the second connecting hole 12 is arranged in the flange portion 14.

[0050] Among them, the groove portion 13 is specifically set in a U shape, so that the groove portion 13 can be sleeved on the mounting frame. When the groove portion 13 is sleeved on the mounting frame, the first fastener 4 passes through the first connecting hole 11 on the groove portion 13, and is threaded or abutted with the mounting frame to achieve a stable connection between the connecting base 1 and the mounting frame. The extension direction of the flange portion 14 requires the back of the display box to be set parallel. The extension length of the flange portion 14 needs to be matched according to the connection width between the display boxes. During the connection process, the flange portion 14 provided on the left side of the groove portion 13 corresponds to one display box, and the flange portion 14 provided on the right side of the groove portion 13 corresponds to another display box. By connecting the two flange portions 14 on the base 1, two adjacent display boxes are connected together to form an integral structure.

[0051] like Figures 1 to 3As shown, in one embodiment of the present application, the second connection hole 12 includes a circular hole portion 121 and a long hole portion 122 that are connected to each other. Among them, the circular hole portion 121 is the starting part of the second connection hole 12, and its main function is to facilitate the penetration of the second fastener 5. The diameter of the circular hole portion 121 matches the diameter of the second fastener 5 to ensure that the second fastener 5 can penetrate the circular hole portion 121. The long hole portion 122 extends laterally along one side of the circular hole portion 121, and the second fastener 5 can move in the long hole portion 122, so that the second fastener 5 has a certain activity space. Through the movement of the second fastener 5 in the long hole portion 122, the installation position of the second fastener 5 can be flexibly adjusted to meet the connection requirements of display cabinets of different specifications, which not only improves the versatility of the connection device, but also simplifies the installation process and reduces the difficulty of operation. It is worth noting that the diameter of the circular hole portion 121 is greater than the width of the long hole portion 122. The purpose of this arrangement is to ensure the movement of the second fastener 5 in the long hole portion 122 and prevent the second fastener 5 from accidentally falling out of the long hole portion 122, so that when using the LED box connection device of the present application, there is no need to find another suitable fastener.

[0052] like Figures 1 to 5 As shown, in one embodiment of the present application, the length of the third connection hole 21 is smaller than the length of the second connection hole 12 , and along the thickness direction of the flange portion 14 , part of the third connection hole 21 is overlapped with the circular hole portion 121 , or the entire third connection hole 21 is outside the circular hole portion 121 .

[0053] The function of the third connection hole 21 is to limit the movement range of the second fastener 5. After the cushion block 2 is installed, along the thickness direction of the flange portion 14, since part of the third connection hole 21 overlaps with the circular hole portion 121, or the third connection hole 21 is entirely outside the circular hole portion 121, the second fastener 5 can no longer completely enter the circular hole portion 121, and will not escape from the second connection hole 12 from the circular hole portion 121, thereby achieving that the second fastener 5 can move in the second connection hole 12 and the third connection hole 21, but will not escape from the second connection hole 12 and the third connection hole 21.

[0054] like Figures 1 to 5 As shown, in one embodiment of the present application, the LED box connection device further includes a third fastener 6. The function of the third fastener 6 is to fix the pad 2 on the connection base 1 to prevent loosening or falling off due to vibration, impact and other factors during subsequent use. The third fastener 6 can flexibly select various fastening methods, including but not limited to screws, rivets, pins, etc., to meet the needs of different application scenarios. Specifically, when a screw is used as the third fastener 6, the corresponding threaded holes can be preset on the pad 2 and the connection base 1, and the screw can be screwed in to achieve fastening.

[0055] like Figure 6 As shown, in one embodiment of the present application, the second fastener 5 includes a fastening head 51, a connecting rod 52 and a screwing portion 53. The surface of the fastening head 51 has threads for threaded connection with the mounting hole of the display box. The screwing portion 53 is convenient for manually screwing the second fastener 5 during installation. The connecting rod 52 serves as a connecting portion between the fastening head 51 and the screwing portion 53. In order to ensure that the second fastener 5 can move in the long hole portion 122 and will not accidentally fall out during the connection process, the diameters of the fastening head 51 and the screwing portion 53 are both larger than the diameter of the connecting rod 52, and the diameter of the fastening head 51 is also larger than the width of the long hole portion 122.

[0056] like Figure 2 As shown, in one embodiment of the present application, the length L of the connecting rod portion 52 is greater than the sum of the thicknesses l of the flange portion 14 and the cushion block 2. Only when L is greater than l, the fastening head 51 of the second fastener 5 can pass through the flange portion 14 and the cushion block 2 and connect with the threaded hole inside the display box. The screwing length of the fastening head 51 and the threaded hole of the display box is equal to the difference between L and l. When the difference between L and l is larger, the screwing length is longer, and the connection is more stable and reliable.

[0057] like Figure 3 As shown, in one embodiment of the present application, the number of second connection holes 12 on the flange portion 14 is multiple. By increasing the number of second connection holes 12, multiple second fasteners 5 can be fixed to the display box, thereby ensuring that the connection between the connection base 1 and the display box is more secure. This multi-point fixing method effectively reduces the risk of loose connection or damage caused by excessive force on a single point.

[0058] like Figure 1 As shown, in one embodiment of the present application, the number of the pads 2 is at least two. By providing a plurality of pads 2, it is possible to increase the layout of the pads 2 connected to the connection base 1, so that the force between the connection base 1 and the display box is more uniform. The pads 2 are symmetrically connected to the flange 14, thereby effectively preventing deformation or damage of the connection part due to uneven force.

[0059] The present application also provides an LED display device, including a display box, a mounting frame, and the LED box connecting device in the above embodiment. The display box is the core component of the entire LED display device, and is used to carry the display screen and other functional components. The mounting frame is generally a square tube frame, which has excellent load-bearing capacity and stability. The LED box connecting device is used to connect the display box to the mounting frame. Since the LED display device has the LED box connecting device in the above embodiment, it also has the advantages of the LED box connecting device in the above embodiment.

[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
