• at least two middle frames spliced together, said middle frame has a rectangular outer contour with a corner region at each of the four corners of said rectangular, at least one of said corner regions is provided with a splicing plate assembly zone for cooperating with said splicing plate, said splicing plate assembly zone is provided with a splicing screw hole and a positioning pin hole;
• at least one splicing plate for splicing said at least two middle frames;
• at least two display modules, each said display module is mounted on the front side of each said middle frame respectively;
• and
• at least two back covers, each said back cover is mounted on the rear side of each said middle frame, respectively;
• wherein said splicing plate includes a plate body and a first threaded fastener, said plate body is provided with a splicing through hole and a positioning pin, said positioning pin is integrally formed with said plate body, said positioning pin is configured to cooperate with said positioning pin hole, said splicing through hole and said splicing screw hole are configured to cooperate with said first threaded fastener to securely connect said splicing plate with said middle frame.

A splicing display screen, comprising:

• a first middle frame and a second middle frame, each of which includes a front side and a rear side opposite to the front side;
• at least two display modules, wherein each display module is installed on the front side of the respective middle frame;
• and
• at least two back covers, each installed on the rear side of the respective middle frame;
• wherein the adjacent side beams of the first middle frame and the second middle frame are respectively provided with corresponding first electrical through-hole and second electrical through-hole;
• a first electrical interface component is installed on the back cover of the first middle frame, which includes a fixed part that is connected to the back cover and a movable part that is movably connected to the fixed part;
• and the movable part can slide in the first direction and is connected to the first electrical interface via a second fastener;
• wherein the second middle frame is equipped with a second electrical interface that corresponds to the first electrical interface;
• said second electrical interface is fixedly connected to the second middle frame and exposed through the second electrical through-hole;
• and the first electrical interface can slide in the first direction via the movable part to connect to or disconnect from the second electrical interface through the first electrical through-hole.

A middle frame, comprising:

• four side beams forming a rectangular outer frame;
• wherein the four side beams include a first side beam and a second side beam;
• wherein the first side beam is provided with a first fixing hole and a first adjustment hole, and the second side beam is arranged opposite to the first side beam;
• wherein the second side beam is provided with a second fixing hole, which corresponds in position to the first fixing hole;
• wherein the first adjustment hole is configured to cooperate with a first adjustment component to adjust a gap between the adjacent middle frames;
• and
• wherein the first adjustment component comprises a first bolt, including a bolt head and a stud, and the length of the stud is greater than the depth of the first adjustment hole.
