[0028] Referring to Figures 3 - 7 , an embodiment of the present utility model provides a corner lock structure 200 for rapid assembly of a display screen module, including a connection piece 210 and locking components 220 provided at the four corners of the box body 110 of the LED display screen module 100. Four locking rods 211 are provided on the connection piece 210. The locking component 220 includes a locking hole 112 provided on the box body 110. Referring to Figure 1 and Figure 2 , the four locking rods 211 on the connection piece 210 are respectively inserted into the locking holes 112 on the box bodies 110 of the adjacent four LED display screen modules 100 assembled (only the assembly of two LED display screen modules 100 is shown in the figure), so as to assemble the four LED display screen modules 100 together.

[0029] Specifically, the locking assembly 220 further includes a locking piece 221. An arc-shaped notch 2211 is provided on one side of the locking piece 221 close to the locking hole 112. The locking piece 221 is rotatably connected to the box body 110. The box body 110 has a locking position and an unlocking position. The locking piece 221 rotates between the locking position and the unlocking position. When the locking piece 221 rotates to the unlocking position on the box body 110, the arc-shaped notch 2211 is concentric with the locking hole 112. At this time, the locking rod 211 can be inserted into the locking hole 112 or taken out from the locking hole 112. When the locking piece 221 rotates to the locking position on the box body 110, the side wall of the arc-shaped notch 2211 abuts against the locking rod 211, thereby fixing the locking rod 211 in the locking hole 112 and preventing the locking rod 211 from being taken out from the locking hole 112, and further ensuring the stability of the assembled LED display module 100.

[0030] In this embodiment, referring to Figure 2 and Figure 3 , a receiving groove 111 is provided on one side of the box body 110. The locking hole 112 is located at the bottom of the receiving groove 111. When the locking rod 211 is inserted into the locking hole 112, the surface height of the connecting piece 210 is lower than the surface height of the box body 110, so that the connecting piece 210 is received in the receiving grooves 111 of the four LED display modules 100 of the assembled display screen. Further, the connecting piece 210 has four arms, and the four arms are arranged in an annular array. A locking rod 211 is provided on each arm. The end of the arm is an arc-shaped surface, and the side wall of the receiving groove 111 is also an arc-shaped surface, so as to improve the structural stability and aesthetics.

[0031] In some embodiments, referring to Figures 3 - 5 , two limiting holes 113 are provided at the bottom of the receiving groove 111, and two limiting posts 213 corresponding to the limiting holes 113 are provided on the connecting piece 210. When the locking rod 211 is inserted into the locking hole 112, the limiting posts 213 are inserted into the limiting holes 113, thereby improving the stability of the connecting piece 210 after installation and preventing the connecting piece 210 from shaking.

[0032] Further, referring to Figures 3 - 5, a retaining block 212 is provided at one end of the locking rod 211 away from the connecting piece 210. The diameter of the retaining block 212 is larger than that of the locking rod 211. When the locking piece 221 is rotated until the side wall of the arc-shaped notch 2211 abuts against the locking rod 211, the locking piece 221 is located directly above the retaining block 212. That is, when the locking rod 211 moves out of the locking hole 112, the locking piece 221 blocks the movement of the retaining block 212, thereby preventing the locking rod 211 from disengaging from the locking hole 112.

[0033] In this embodiment, referring to Figure 5 , an installation groove 115 communicating with the locking hole 112 is provided on the box body 110. A pressing piece 223 is connected to the box body 110. The pressing piece 223 covers the installation groove 115 to form an installation space. The locking piece 221 is located in the installation space. A central hole 2212 is provided on the locking piece 221. A rotating shaft 222 is rotatably connected in the central hole 2212. A fixing hole 116 is provided at the bottom of the installation groove 115. A pin is provided on the pressing piece 223. One end of the rotating shaft 222 is connected to the fixing hole 116, and the other end of the rotation is fixedly connected to the pin. In this way, the locking piece 221 can rotate based on the rotating shaft 222. Limited by the installation space, the locking piece 221 can rotate between the locking position and the unlocking position.

[0034] Further, referring to Figure 6 and Figure 7 , a circular protrusion 2213 is provided on one side of the locking piece 221. The circular protrusion 2213 is in sliding contact with the bottom of the installation groove 115. A washer 2214 is provided on the other side of the locking piece 221. A sliding block 2215 is provided on the washer 2214. The sliding block 2215 is in sliding contact with the pressing piece 223. Through the arrangement of the circular protrusion 2213 and the sliding block 2215, the friction area between the locking piece 221 and the box body 110 is reduced, that is, the frictional force when the locking piece 221 rotates is reduced, which is convenient for the staff to operate the rotation of the locking piece 221 with less effort.

[0035] Further, referring to Figure 3 and Figure 8 , a corner lock handle 226 is connected to the side of the locking piece 221 away from the arc-shaped notch 2211. A guiding mark 114 is provided on the box body 110. The guiding mark 114 is arranged corresponding to the corner lock handle 226. The guiding mark 114 is used to identify the unlocking position and the locking position. When the corner lock handle 226 is aligned with the unlocking position, that is, the locking piece 221 is located at the unlocking position. When the corner lock handle 226 is aligned with the locking position, that is, the locking piece 221 is located at the locking position. This is convenient for the staff to operate.

[0036] In some embodiments, with reference to Figures 3 - 5 , the locking assembly 220 further includes a fixing member for fixing the position of the locking piece 221. Specifically, the fixing member includes a connecting block 224 disposed on the locking piece 221. The connecting block 224 is integrally formed between the locking piece 221 and the corner lock handle 226. A spring detent 225 is disposed on the connecting block 224, and a plurality of positioning holes 227 for cooperating with the spring detent 225 are disposed on the pressing piece 223. When the connecting block 224 rotates with the locking piece 221, the spring detent 225 passes through the connection line of the plurality of positioning holes 227, and when the spring detent 225 is directly above the positioning hole 227, the spring detent 225 is inserted into the positioning hole 227 under the action of its own elastic force. In this way, when the operator rotates the corner lock handle 226 to rotate the locking piece 221, the cooperation between the spring detent 225 and the positioning hole 227 generates a damping feeling. When the spring detent 225 moves to the positioning holes 227 at both ends of the pressing piece 223, the locking piece 221 is in the locked position or the unlocked position. Thus, when the locking rod 211 is inserted into the locking hole 112 and the locking piece 221 is rotated to the locked position, the spring detent 225 is inserted into the positioning hole 227 at the end of the pressing piece 223. Without a large external force, the locking piece 221 will not move, ensuring the reliability of the corner lock structure 200 after assembling the LED display module 100; when the locking piece 221 is in the unlocked position, the spring detent 225 is inserted into the positioning hole 227 at the other end of the pressing piece 223. In this way, when not assembled, the corner lock handle 226 in a single LED display module 100 will not shake randomly.

[0037] The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
