[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood by specific circumstances.

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figure 1-Figure 5As shown, a liquid crystal display screen that is easy to disassemble and assemble is composed of a display screen body 1, a top frame ear group 2, a bottom frame ear group 3, a top wall frame 6 and a bottom wall frame 7;

[0021] The top frame ear group 2 is fixedly mounted on the top of the back side of the display screen body 1, and the bottom frame ear group 3 is fixedly mounted on the bottom of the back side of the display screen body 1. The top frame ear group 2 is mounted with a top horizontal column 4. Specifically, the top frame ear group 2 is composed of two top frame ears, which are fixed on both sides of the top horizontal column 4, and the bottom frame ear group 3 is fixedly mounted with a bottom horizontal column 5;

[0022] A top elastic pin frame 8 is fixedly installed on one side of the top wall frame 6, and a bullet cavity 9 is arranged in the top elastic pin frame 8, and a plug-in elastic pin 12 is inserted in the bullet cavity 9, and the bottom end of the plug-in elastic pin 12 extends to the bottom of the top elastic pin frame 8, and the top end of the plug-in elastic pin 12 extends to the top of the top elastic pin frame 8. A spring pressing ear 13 is fixedly installed in the plug-in elastic pin 12 in the bullet cavity 9, and a spring 10 is pressed between the spring pressing ear 13 and the top cavity wall of the bullet cavity 9. The spring 10 is used to press the spring pressing ear 13 to drive the plug-in elastic pin 12 to be in a downward pressure blocking state for a long time;

[0023] A bottom hanging bracket 17 is fixedly installed at the bottom of the bottom wall frame 7, and the bottom cross column 5 is hung in the hanging groove of the bottom hanging bracket 17 and can be rotated, so that the bottom hanging installation is conveniently realized.

[0024] like Figure 1-Figure 5 As shown, the utility model also discloses the following more optimized specific structures:

[0025] A plug-in cap 11 is installed at the top of the plug-in pin 12, and manual plug-in is performed when disassembly is required. A curved surface 14 is provided at the bottom of the plug-in pin 12, which is convenient for the display screen body 1 to be rotated and buckled without manually plugging the plug-in cap 11. The cross-section of the top horizontal column 4 is semicircular, with one side being a plane and the other side being a curved surface, which is convenient for cooperating with the curved surface 14 for one-way passage.

[0026] The bottom hanging frame 17 is composed of an arc-shaped bearing slot frame 16 and arc slot vertical walls 15 installed on both sides of the top of the arc-shaped bearing slot frame 16 .

[0027] The display screen main body 1 is composed of a frame 19 and a screen body 18 installed in the frame 19 .

[0028] The top wall frame 6 and the bottom wall frame 7 are both provided with screw holes, through which the top wall frame 6 and the bottom wall frame 7 are fixed to the wall with screws.

[0029] like Figure 1-Figure 5The LCD screen that is easy to disassemble and assemble as shown needs to first fix the top wall frame 6 and the bottom wall frame 7 to the wall by screws, then lift the display screen body 1, so that the bottom horizontal column 5 at the bottom of the back side is placed in the hanging groove of the bottom hanging frame 17, and then flip the display screen body 1, so that the top horizontal column 4 at the top of the back side is pressed to the side of the arc-pressing surface 14 at the bottom of the plug-in elastic pin 12, and the arc-pressing surface 14 is forced to drive the plug-in elastic pin 12 to move upward, and when the top horizontal column 4 continues to be pressed and displaced to the other side of the plug-in elastic pin 12, the plug-in elastic pin 12 moves downward under the action of the spring, thereby blocking the plane side of the top horizontal column 4, and realizing quick installation;

[0030] When it is necessary to disassemble, the plug-in cap 11 is pulled upward, and the blocking function of the plug-in elastic pin 12 disappears, so that the display screen body 1 is turned out and removed from the platform.
