Fig. 1 is a perspective view of a first box 101, fig. 2 is a perspective view of a second box 102, fig. 3 is a schematic cross-sectional view of a positioning structure of a box of an LED display screen, and referring to fig. 1 to 3, according to an aspect of the present invention, the positioning structure of the box of the LED display screen includes: a first casing 101 and a second casing 102. The first box 101 has a first side 103, and the positioning member 104 is detachably mounted on the first side 103. The second box 102 can be spliced with the first box 101, the second box 102 has a second side 105, and the second side 105 is provided with a positioning hole 106. When the first box 101 and the second box 102 are spliced, the first side 103 and the second side 105 are opposite, and the positioning member 104 can be inserted into the positioning hole 106. The positioning member 104 is detachable from the positioning hole 106 in a state where the first casing 101 and the second casing 102 are joined.

In this embodiment, since the detachable positioning member 104 is disposed on the first box 101, the positioning member 104 can be machined and then mounted on the first box 101 by machining, so as to improve the machining accuracy and the mounting accuracy of the positioning member 104 and prevent the box splicing dislocation of the LED display screen. In addition, since the positioning member 104 can be removed from the positioning hole 106 in a state where the cases of the LED display panels are joined to each other, the cases of the LED display panels joined to each other can be easily removed.

Specifically, for example, when the box is removed from the top-bottom direction, since the positioning member 104 is removed in advance, when the box (the first box 101 in fig. 3) above is removed, the box above can be directly removed in the left-right direction or the front-back direction without an upward lifting operation, and the difficulty of removal can be reduced.

With continued reference to fig. 3, in some embodiments, in order to improve the machining precision of the positioning element 104 and improve the versatility of the positioning element 104, the portion of the positioning element 104 inserted into the positioning hole 106 is cylindrical. Specifically, for example, a cylindrical positioning pin can be used for the positioning member 104, and since the cylindrical positioning pin is easily processed with high accuracy and the cylindrical positioning hole 106 is also easily processed with high accuracy, the fitting accuracy between the positioning member 104 and the positioning hole 106 can be improved by using the cylindrical positioning pin as the positioning member 104. The positioning member 104 may be a commercially available positioning pin (i.e., a positioning pin processed in batch by machining or the like), or may be processed according to actual needs.

With continued reference to fig. 2, in some embodiments, the positioning holes 106 include two positioning holes, one of which is located on one side of the second side portion 105 in the length direction (left-right direction in fig. 2) and the other of which is located on the other side of the second side portion 105 in the length direction, and in order to facilitate the alignment between the positioning member 104 and the positioning holes 106, one of the two positioning holes 106 (e.g., the right side in fig. 2) is a kidney-shaped hole extending along the length direction of the second side portion 105.

With continued reference to fig. 3, in some embodiments, in order to easily mount the positioning element 104 and improve the mounting accuracy of the positioning element 104 on the first box 101, the first sidewall 107 of the first side portion 103 is opened with a receiving hole 108 for receiving a portion of the positioning element 104 and positioning the positioning element 104, and the positioning element 104 is locked in the receiving hole 108 by a screw 109. For example, the accommodating hole 108 opens from a side of the first side wall 107 opposite to the second side portion 105, for example, in fig. 3, the accommodating hole 108 opens from bottom to top. Thereby enabling easy installation and positioning of the positioning member 104.

In some embodiments, in order to easily lock the positioning member 104 and improve the installation accuracy of the positioning member 104, the first side wall 107 is further opened with a communication hole 110 communicating with the accommodating hole 108, and the screw member 109 passes through the communication hole 110 and is coupled to the positioning member 104. Specifically, for example, in fig. 3, the communication hole 110 communicates with the accommodation hole 108 in the up-down direction. Correspondingly, one end of the positioning element 104, which is accommodated in the accommodating hole 108, is provided with a threaded hole 111 extending along the axial direction of the positioning element 104. The screw 109, which may be selected from a screw or a bolt, is screwed through the communication hole 110 and the screw hole 111 of the positioning member 104. Since the positioning member 104 can be locked by the screw 109 when the positioning member 104 is accommodated and positioned in the accommodation hole 108, not only can the mounting accuracy of the positioning member 104 be improved, but also the positioning member 104 can be easily locked. Further, since the positioning member 104 is locked by the separate screw member 109 without separately machining a screw hole in the first case 101, it is sufficient to secure the positional accuracy between the positioning member 104 and the accommodation hole 108, and it is not necessary to pay additional attention to the accuracy (e.g., the coaxiality, etc.) between the portion of the positioning member 104 inserted into the positioning hole 106 and the screw hole 111.

In some embodiments, to more easily disassemble the positioning member 104, the positioning member 104 has a cylindrical shape, the positioning hole 106 penetrates through the second sidewall 112 of the second side portion 105, and the positioning member 104 can be disassembled from the positioning hole 106. Since the positioning hole 106 penetrates the second side wall 112, the positioning member 104 can be directly pulled out from one end of the second side portion 105 after the screw 109 of the locking positioning member 104 is removed, and thus the positioning member 104 can be easily removed.

Fig. 4 is a schematic cross-sectional view of another embodiment of a positioning structure of a box body of an LED display panel, referring to fig. 4, in some embodiments, in order to more easily detach the positioning element 104, the first side portion 103 is provided with a through hole 113 penetrating through the first side wall 107 of the first side portion 103, the through hole 113 receives and positions the positioning element 104, and one end of the positioning element 104 penetrates through the through hole 113 and is inserted into the positioning hole 106. In this embodiment, the positioning element 104 may be configured in a step shape, the small diameter end 114 of the positioning element 104 is inserted into the positioning hole 106 through the through hole 113, and the large diameter end 115 of the positioning element 104 is directly supported on the first sidewall 107. Thus, when the spacer 104 is removed, the spacer 104 can be directly pulled out from the through hole 113 to remove the spacer 104.

A spacer (not shown) having a diameter larger than that of the spacer 104 may be fastened to one end of the columnar spacer 104, and the spacer may be fastened to the first sidewall 107 so that the spacer 104 can be supported by the first sidewall 107. When the positioning member 104 and the spacer are detached from each other, the positioning member 104 can be directly pulled out from one end of the second side portion 105, and thus the positioning member 104 can also be easily detached.

With continued reference to fig. 3, in some embodiments, the first enclosure 101 is disposed above the second enclosure 102. Specifically, for example, when the positioning member 104 has a cylindrical shape and the positioning hole 106 penetrates the second sidewall 112, the first casing 101 provided with the positioning member 104 is disposed above the second casing 102 provided with the positioning hole 106. After the positioning element 104 is detached, the positioning element 104 can directly fall off under the action of gravity. Therefore, the positioning member 104 can be easily detached.
