[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-5 A splicing LCD display includes a main body 1, a quick-installation mechanism, and a maintenance mechanism. The quick-installation mechanism includes a first mounting frame 2, a fixing plate 3, a spring, and a fixing bracket 5. The main body 1 is mounted on and detachably connected to the first mounting frame 2. The fixing plate 3 is mounted on the first mounting frame 2 and is connected to the main body 1. The spring is mounted on the fixing plate 3, and its other end is fixedly connected to the fixing plate 3. The fixing bracket 5 is mounted on and connected to the fixing plate 3. The maintenance mechanism includes a second mounting frame 6, a bidirectional motor 7, a lead screw 8, a sliding frame 9, a connecting rod 10, and auxiliary components. The bidirectional motor 7 is fixedly mounted in the second mounting frame 6, and its two output ends are fixedly connected to the lead screw 8. The lead screw 8 rotates in the second mounting frame 6. The sliding frame 9 is mounted in the second mounting frame 6 and is slidably connected to the second mounting frame 6. One end of the connecting rod 10 is rotatably connected to the sliding frame 9, and the other end of the connecting rod 10 is rotatably connected to the fixing bracket 5.

[0032] In this embodiment, the quick installation mechanism includes a first mounting bracket 2, a fixed plate 3, a spring, and a fixed frame 5. In use, the main body 1 is installed onto the first mounting bracket 2. The positioning rod on the first mounting bracket 2 directly enters the positioning hole in the first mounting bracket 2, and the connecting block 19 on the main body 1 enters the first mounting bracket 2. Then, the fixed plate 3 is installed onto the first mounting bracket 2, and the second positioning rod 21 on the first mounting bracket 2 enters the positioning groove 25 in the fixed plate 3. Pulling the fixed frame 5 stretches the spring installed in the placement groove 24. Rotating the fixed plate 3 causes the first positioning rod 18 on the connecting block 19 to enter the entry hole 26 in the fixed plate 3. Subsequently, as the fixed plate 3 rotates, the first positioning rod 18 rotates in the connecting groove 27 in the fixed plate 3. Once the fixed plate 3 and the first positioning rod 18 are fixed together, the fixed frame 5 is released. The stretched spring causes the fixed frame 5 to directly insert into the second positioning hole 22 in the second positioning rod 21, thereby fixing the fixed plate 3 in place.

[0033] In this embodiment, the maintenance mechanism includes a second mounting frame 6, a bidirectional motor 7, a lead screw 8, a sliding frame 9, a connecting rod 10, and auxiliary components. In use, the bidirectional motor 7 installed in the second mounting frame 6 drives the lead screw 8 to rotate. The rotation of the lead screw 8 allows the sliding frame 9 installed on the lead screw 8 to slide in the positioning frame 17 on the second mounting frame 6. The sliding of the sliding frame 9 changes the position of the connecting rod 10, thereby pushing the first mounting frame 2 out of the second mounting frame 6. At this time, the main body 1 on the first mounting frame 2 can be maintained.

[0034] In this embodiment, the auxiliary components include a fixing plate 11, expansion bolts 12, and a pressure plate 13. In use, the fixing plate 11 is installed in the fixing groove 14 on the second mounting bracket 6. Holes are drilled in the wall through the insertion groove 15 on the fixing plate 11. After drilling, the expansion bolts 12 can be installed in the insertion groove 15, thereby completing the fixing of the fixing plate 11 to the second mounting bracket 6. When the first mounting bracket 2 retracts the second mounting bracket 6, the first mounting bracket 2 needs to contact the contact block 16 to protect the main body 1. When repairing the main body 1 on the first mounting bracket 2, the pressure plate 13 installed on the second mounting bracket 6 is taken out to support the first mounting bracket 2.

[0035] Example 2:

[0036] In summary, during use, the main body 1 is first installed onto the first mounting bracket 2. The positioning rod on the first mounting bracket 2 directly enters the positioning hole in the first mounting bracket 2, and the connecting block 19 on the main body 1 enters the first mounting bracket 2. Then, the fixing plate 3 is installed onto the first mounting bracket 2, and the second positioning rod 21 on the first mounting bracket 2 enters the positioning groove 25 in the fixing plate 3. Pulling the fixing bracket 5 stretches the spring installed in the mounting groove 24. Rotating the fixing plate 3 causes the first positioning rod 18 on the connecting block 19 to enter the entry hole 26 in the fixing plate 3. Subsequently, as the fixing plate 3 rotates, the first positioning rod 18 rotates in the connecting groove 27 in the fixing plate 3. After the fixing plate 3 and the first positioning rod 18 are fixed together, the fixing bracket 5 is released. The stretched spring causes the fixing bracket 5 to directly insert into the second positioning hole 22 in the second positioning rod 21, thus fixing the fixing plate 3. When the main body 1 needs repair, the fixing plate 3 is then installed onto the second mounting bracket 6. Driven by the bidirectional motor 7, the lead screw 8 is rotated directly. The rotation of the lead screw 8 allows the sliding bracket 9 mounted on the lead screw 8 to slide in the positioning bracket 17 on the second mounting bracket 6. The sliding of the sliding bracket 9 causes the position of the connecting rod 10 to change, thereby pushing the first mounting bracket 2 out of the second mounting bracket 6. At this time, the main body 1 on the first mounting bracket 2 can be repaired. When installing and repairing the main body 1, the second mounting bracket 6 needs to be fixed to the wall. The fixing plate 11 is installed in the fixing groove 14 on the second mounting bracket 6. A hole is drilled in the wall through the insertion groove 15 on the fixing plate 11. After drilling, the expansion bolt 12 can be installed in the insertion groove 15 to complete the fixation of the fixing plate 11 and the second mounting bracket 6. When the first mounting bracket 2 retracts into the second mounting bracket 6, the first mounting bracket 2 needs to contact the contact block 16 to protect the main body 1. When repairing the main body 1 on the first mounting bracket 2, the pressure plate 13 mounted on the second mounting bracket 6 is taken out to support the first mounting bracket 2.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
