[0030] Reference Figure 1-5The utility model provides an embodiment: a liquid crystal splicing screen that is easy to maintain, including a display screen 1, four rear corners of the display screen 1 are fixedly connected with connecting pieces 10, the upper left and right sides of the connecting pieces 10 are rotatably connected with two-way threaded rods 12 on the sides close to each other, the middle end of the two-way threaded rod 12 is fixedly connected with a rotating block 11, the outer shaft of the two-way threaded rod 12 is threadedly connected with two sliding pieces 14, the two sliding pieces 14 are connected with a mounting column 5 on the side close to each other through a telescopic component, the display screen 1 is installed on the wall through the rear mounting column 5, the two sliding pieces 14 are separated by a plug-in component, and the plug-in component is moved toward the display screen by rotating the rotating block 11. The screen 1 moves on both sides to splice the plug-in components of the display screen 1 with the plug-in components of another display screen 1. The upper two sliding members 14 and the lower two sliding members 14 are connected by a connecting rod 6. The movement of the sliding member 14 on the bidirectional threaded rod 12 will drive the lower sliding member 14 to move on the sliding rod 4 through the connecting rod 6. A snap-fit ​​groove is provided on the right side of the top of the connector 9, and the blocking block 3 is arranged in the snap-fit ​​groove. An directional groove is provided on the right end of the adjusting member 8, and the contraction shaft 7 is rotatably connected inside the directional groove. The front ends of the two lower sliding members 14 are slidably connected with the sliding rod 4, and the left and right ends of the sliding rod 4 are fixedly connected to the two lower connecting members 10.

[0031] The telescopic assembly includes an adjusting member 8 fixedly connected to one side of the sliding member 14, a contraction shaft 7 is rotatably connected inside the one side of the adjusting member 8, and one end of the contraction shaft 7 provided with a collar is rotatably connected to the outer wall of the mounting column 5. The movement of the sliding member 14 also drives the adjusting member 8 thereon to move, so that the position state of the contraction shaft 7 in the directional groove provided on the adjusting member 8 changes, so that the display screen 1 will approach the direction of the mounting column 5;

[0032] The plug-in assembly includes a connector 2 fixedly connected to the left end of the left sliding member 14 and a connector 2 9 fixedly connected to the right end of the right sliding member 14. A sliding groove is arranged on the left side of the top of the connector 2, and a spring 13 is fixedly connected to the bottom end of the sliding groove. A blocking block 3 is fixedly connected to the other end of the spring 13. When the connector 2 moves to the edge of the display screen 1, it will be inserted into the connector 2 9 of the other display screen 1. The blocking block 3 on the connector 2 will be compressed into the interior of the connector 2 by the extrusion of the connector 2 9. When the connector 2 extends into the engaging groove at the top of the connector 2 9, the blocking block 3 will be engaged with the engaging groove on the connector 2 9 through the spring 13 at the bottom.

[0033] Working principle: The display screen 1 is installed on the wall through the rear mounting column 5. After the display screen 1 is installed, the bidirectional threaded rod 12 inside the rotating block 11 is rotated by rotating the rotating block 11. The rotation of the bidirectional threaded rod 12 causes the sliding member 14 thereon to move to both sides. The movement of the sliding member 14 on the bidirectional threaded rod 12 will drive the lower sliding member 14 to move on the sliding rod 4 through the connecting rod 6. The movement of the sliding member 14 also drives the adjustment member 8 thereon to move, so that the position state of the contraction shaft 7 in the directional groove provided on the adjustment member 8 changes, so that the display screen 1 will approach the direction of the mounting column 5. The movement of the sliding member 14 will also drive the connector 1 2 and the connector 2 9 thereon to both sides of the display screen 1 When connector 1 is moved to the edge of display screen 1, it will be inserted into connector 2 9 of another display screen 1, and the blocking block 3 on connector 1 2 will be compressed into the inside of connector 1 2 by the extrusion of connector 2 9. When connector 1 2 extends into the engaging groove at the top of connector 2 9, blocking block 3 will be engaged with the engaging groove on connector 2 9 through the spring 13 at the bottom, so that connector 1 2 and connector 2 9 are fixed, and the two display screens 1 are spliced. When it is necessary to repair display screen 1, blocking block 3 can be pressed first and then rotating block 11 to separate the two, and then rotating block 11 can be continued to make the retracting shaft 7 push display screen 1, and display screen 1 can be pushed out for the convenience of maintenance personnel to repair display screen 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
