In order to solve the LED display module among the prior art and only can maintain or only can maintain from the rear portion from the front portion, lead to the narrow problem of application range of LED display module, the utility model provides an LED display module.

As shown in fig. 1 and fig. 6, the LED display assembly includes a box frame 10, a first magnetic attraction structure 20, a lamp panel 30 and a second magnetic attraction structure 40, wherein the box frame 10 is provided with a connection through hole 11, the first magnetic attraction structure 20 is movably disposed through the connection through hole 11, the second magnetic attraction structure 40 is disposed on the lamp panel 30, and the second magnetic attraction structure 40 is magnetically engaged with the first magnetic attraction structure 20 to fixedly connect the lamp panel 30 and the box frame 10; wherein, first magnetism is inhaled structure 20 and is included the first adjustment end that is close to second magnetism and inhale structure 40 setting and keep away from the second adjustment end that second magnetism inhales structure 40 setting to through the position of first adjustment end and/or the first magnetism of second adjustment end adjustment structure 20 in connect the through hole 11 department, thereby adjust the roughness of lamp plate 30.

The embodiment of the application provides an LED display assembly which can be maintained from the front part and the rear part, particularly, when the LED display assembly needs to be maintained from the front part, a lamp panel 30 is detached, a first magnetic attraction structure is moved at a connecting through hole 11 by utilizing a first adjusting end, and a second magnetic attraction structure 40 and the lamp panel 30 are driven to move by a first magnetic attraction structure 20, so that the relative position between the lamp panel 30 and a box body frame 10 is adjusted, and the adjustment of the flatness of the LED display assembly is realized; when the LED display component is required to be maintained from the rear part, the second adjusting end is utilized to enable the first magnetic attraction structure to move at the connecting through hole, the second magnetic attraction structure is driven by the first magnetic attraction structure to move with the lamp plate, so that the relative position between the lamp plate and the box body frame is adjusted, and the adjustment of the flatness of the LED display component is realized.

It should be noted that, the flatness adjustment of the lamp panel 30 related to the present application includes two meanings, one meaning the flatness of a lamp panel 30 itself, for example, after the lamp panel 30 is installed on the box frame 10, the left side of the lamp panel 30 is higher than the right side, the position of the first magnetic attraction structure 20 located on the right side of the lamp panel 30 is adjusted, so that the first magnetic attraction structure 20 pushes the corresponding second magnetic attraction structure 40 to move, thereby pushing the right side of the lamp panel 30 to move to the side far away from the box frame 10, and further making the right side of the lamp panel 30 flush with the left side of the lamp panel 30; another meaning means, as shown in fig. 2, there is the unevenness between two adjacent lamp plates 30, and the display surface of the lamp plate 30 that is located the top, which is far away from the box frame 10, is lower than the display surface of the lamp plate 30 that is located the bottom, which is far away from the box frame 10, and through adjusting the position of the first magnetic attraction structure 20 corresponding to the lamp plate 30 that is located the top, the first magnetic attraction structure 20 pushes the second magnetic attraction structure 40 and the lamp plate 30 corresponding thereto, so that the display surface of the lamp plate 30 that is located the top is flush with the display surface of the lamp plate 30 that is located the bottom.

As shown in fig. 1, fig. 2 and fig. 6, connecting hole 11 is the screw hole, and first magnetism inhale structure 20 have with connecting hole 11 screw-thread fit's external screw thread, through rotatory first adjustment end and/or second adjustment end, drive first magnetism inhale structure 20 and rotate and make first magnetism inhale structure 20 and remove along connecting hole 11 to promote the second magnetism inhale structure 40 and the motion of lamp plate 30 through first magnetism inhale structure 20, realize the adjustment of the roughness of LED display module. In the illustrated embodiment of the present application, the first magnetic attraction structure 20 is connected to the box frame 10 by a screw thread, and a fixing member for fixing the first magnetic attraction structure 20 to the box frame 10 is omitted by using a self-locking function of the screw thread itself, so that the first magnetic attraction structure has the characteristics of simple structure and convenience in operation.

In an optional embodiment of the present application, a sliding connection between the first magnetic attraction structure 20 and the box frame 10 may also be adopted, so that the first magnetic attraction structure 20 is movably disposed at the connection through hole 11, and after the position of the first magnetic attraction structure 20 on the box frame 10 is adjusted, the first magnetic attraction structure 20 is fixedly connected to the box frame 10 by a fixing member.

When the first adjusting end or the second adjusting end is located in the connecting through hole 11, the user is inconvenient to extend into the connecting through hole 11 to rotate the first magnetic attraction structure 20; also, it is considered that when the size of the first magnetic attraction structure 20 is small, the user is inconvenient to hold the first magnetic attraction structure 20 to rotate the same. As shown in fig. 3 to fig. 5, the LED display assembly further includes a first adjusting tool 50 and a second adjusting tool 60, the first adjusting tool 50 is in driving connection with the first adjusting end, and the second adjusting tool 60 is in driving connection with the second adjusting end, so that the first magnetic attraction structure 20 is driven to rotate by the first adjusting tool 50 or the second adjusting tool 60. In this way, the first magnetic attraction structure 20 can be easily driven to rotate by the first adjusting tool 50 or the second adjusting tool 60 with less effort. In addition, in consideration of the difference between the first adjusting end and the second adjusting end in terms of structure and size, two different adjusting tools are selected to adjust the position of the first magnetic attraction structure 20 in order to better match with the first adjusting end and the second adjusting end in a driving manner.

The following is explained in detail with reference to fig. 2 to 5: when the display surface between two adjacent lamp panels 30 is uneven as shown in fig. 2, the actual situation on site is considered, and front maintenance or rear maintenance is selected, when front maintenance is selected, as shown in fig. 3, the lamp panels 30 are detached, then the first magnetic attraction structure 20 is driven to rotate by using the first adjusting tool 50, the position of the first magnetic attraction structure 20 is adjusted, after the adjustment, the lamp panels 30 are installed on the box body frame 10, whether the display surfaces of the two lamp panels 30 are flat or not is observed, and if the display surfaces are uneven, the steps are repeated for adjustment until the display surfaces are in the flat state as shown in fig. 4; when selecting the post-maintenance, need not dismantle lamp plate 30, as shown in fig. 5, directly utilize second adjustment tool 60 to drive first magnetic structure 20 and rotate, adjust the position of first magnetic structure 20, observe whether the display surface of two lamp plates 30 has leveled up to the leveling state as shown in fig. 5.
