[0005] In one of the embodiments, the LED display box frame further includes a locking screw and a locking hole, wherein the locking screw is arranged at the lower end of the frame body, and the locking hole is arranged at the upper end of the frame body.

[0006] In one embodiment, the upper positioning structure is a cylindrical positioning column.

[0007] In one of the embodiments, the cylindrical positioning column is fixed to the frame body by rotating and tightening the thread.

[0008] In one of the embodiments, the upper positioning hole is a U-shaped hole, and the cross-sectional shape of the U-shaped hole is composed of a rectangle and a trapezoid, wherein the upper portion is a rectangle and the lower portion is a trapezoid.

[0009] In one embodiment, the side positioning structure is a wedge-shaped block structure, and the wedge-shaped block structure is bent downward to form the guide surface.

[0010] In one embodiment, the side positioning groove is a wedge-shaped groove, and the upper and lower sides of the wedge-shaped groove cross section are inclined inwards.

[0011] In one embodiment, the wedge block structure includes a guide angle and a pressure angle. The guide surface extends upward to the frame of the frame body to form the guide angle, and the other surface of the wedge block structure bent downward to the frame inward to form the pressure angle.

[0012] In one embodiment, the guide angle ranges from 120 degrees to 135 degrees, and the pressure angle ranges from 10 degrees to 17 degrees.

[0013] In one of the embodiments, the angle between the upper side of the wedge-shaped groove cross section and the horizontal direction and the guide angle are complementary, and the angle between the lower half of the wedge-shaped groove cross section and the horizontal direction and the pressure angle are complementary.

[0014] Compared with the prior art, the utility model has the following beneficial effects: Different from the prior art, the utility model sets a plurality of wedge-shaped block structures and wedge-shaped grooves on both sides of the frame. After the adjacent LED display boxes slide into the wedge-shaped grooves through the guide surfaces on the wedge-shaped block structures, the adjacent LED display boxes are pressed tightly due to the angle setting. At this time, the upper and lower adjacent boxes are fixed by screws set up at the top and bottom to complete the splicing. Rapid positioning, splicing and installation between boxes are realized, and screws are set on the upper and lower frames of the box frame to ensure the flatness of the entire LED display screen.

[0020] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] See also Figure 1 to Figure 2 The utility model provides an LED display box frame including a frame body 1, an upper positioning structure 2, an upper positioning hole 3, a side positioning structure 4 and a side positioning groove 5, wherein the upper positioning structure 2 is arranged at the upper end of the frame body 1, the upper positioning hole 3 is arranged at the lower end of the frame body 1, the side positioning structure 4 is arranged at the side of the frame body 1, and the side positioning groove 5 is arranged at the other side of the frame body 1. The LED display box frame also includes a locking screw 6 and a locking hole 7, the locking screw 6 is arranged at the lower end of the frame body 1, and the locking hole 7 is arranged at the upper end of the frame body 1.

[0025] In some specific embodiments, the upper positioning structure 2 is a cylindrical positioning column (as shown in the figure). The cylindrical positioning column is fixed to the frame body by screwing and tightening. The upper positioning hole 3 is a U-shaped hole.

[0026] Specifically, the cross-sectional shape of the U-shaped hole is composed of a rectangle and a trapezoid (such as Figure 2Trivia), the upper part is a rectangle and the lower part is a trapezoid. The side positioning structure 4 is a wedge-shaped block structure (as shown in the figure), and the wedge-shaped block structure is bent downward to form the guide surface. The side positioning groove 5 is a wedge-shaped groove, and the upper and lower sides of the wedge-shaped groove cross section are inclined inward. The wedge-shaped block structure 4 also includes a guide angle 8 and a pressure angle 9. The guide surface upward to the frame of the frame body constitutes the guide angle 8, and the other side of the wedge-shaped block structure bent downward inward to the frame constitutes the pressure angle 9. The guide angle ranges from 120 degrees to 135 degrees, and the pressure angle ranges from 10 degrees to 17 degrees. Moreover, the angle between the upper side of the wedge-shaped groove cross section and the horizontal direction is complementary to the guide angle, and the angle between the lower half of the wedge-shaped groove cross section and the horizontal direction is complementary to the pressure angle. In a specific embodiment, angle 10 is equal to pressure angle 9, and angle 11 is equal to pressure angle 8. In the optimal embodiment, the guide angle is 135 degrees and the pressure angle is 17 degrees, at which time the assembly splicing effect of the box frame is optimal.

[0027] See also Figure 3 The specific box installation process is as follows: the adjacent boxes are close to each other for splicing, and the guide surface of the side positioning structure 4 makes it slide into the side positioning groove 5 of the adjacent frame. At this time, the positioning structure 2 is in the upper positioning hole 3, and the locking screw 6 is moved left and right to the locking hole 7 and then tightened to complete the splicing installation. Figure 4 This is a schematic diagram after the adjacent box frames on the upper, lower, left and right sides are spliced ​​together.

[0028] The LED box frame designed by the utility model is connected, fixed and locked by locking screws at the top and bottom, and is tightened by wedge blocks at the left and right. The positioning columns prevent front and back misalignment. The upper positioning holes of the U-shaped holes enable adjacent frames to be adjusted with a certain degree of freedom at the left and right when splicing, thereby achieving rapid positioning, splicing and installation between the boxes while ensuring the flatness of the entire LED display screen.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
