[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-4 , an LED digital tube connection mechanism includes a fixed support plate 1 and an LED digital tube body 4. A protective cover 9 is fixedly connected to the front surface of the fixed support plate 1, and a first spring 10 is inserted into the protective cover 9. A rubber pad 8 is fixedly connected to the front surface of the first spring 10, and the front surface of the rubber pad 8 abuts against the LED digital tube body 4. A fixing cover 2 is sleeved on the surface of the LED digital tube body 4, and buckle assemblies 7 are symmetrically and fixedly connected to the upper and lower ends of the fixing cover 2. Limiting strips 3 are symmetrically and fixedly connected to the inner walls of the upper and lower ends of the fixing cover 2.

[0022] Further, referring to Figure 2 , it can be known that a rectangular groove is formed on the left side of the fixing cover 2, a threaded groove is formed on the left side of the fixing cover 2, and a threaded rod 6 is inserted into the threaded groove. A rubber pad 8 is inserted into the rectangular groove, and the rubber pad 8 is connected to the threaded rod 6 through a bearing. The rubber pad 8 is of an arc structure, which is convenient for limiting the connecting wire.

[0023] Further, referring to Figure 3 , it can be known that through holes are symmetrically formed at the upper and lower ends of the fixed support plate 1, and a pull rod 5 is inserted into the through holes. One end of the pull rod 5 inserted into the fixed support plate 1 is fixedly connected to a moving limiting plate 12, and limiting blocks 14 are fixedly connected to the surface of the end of the moving limiting plate 12 away from the pull rod 5. There are two groups of limiting blocks 14, and the surfaces of the two groups of limiting blocks 14 are inclined surfaces. When the buckle assembly 7 moves, it abuts against the surfaces of the limiting blocks 14, and the limiting blocks 14 are forced to move towards both ends.

[0024] Further, referring to Figure 3 and Figure 4 , it can be known that a second spring 13 is sleeved on the surface of the pull rod 5, one end of the second spring 13 is fixedly connected to the inner wall of the fixed support plate 1, and the other end of the second spring 13 is fixedly connected to the surface of the moving limiting plate 12. The second spring 13 deforms under an external force and returns to its original state after the external force is removed, thereby facilitating the reset of the limiting block 14.

[0025] Further, referring to Figure 3 , it can be known that a bearing rod is installed on the left side of the center position inside the fixed support plate 1, a gear 15 is sleeved on the surface of the bearing rod, a first rack 11 is meshed with the left side of the gear 15, and a second rack 16 is meshed with the right side of the gear 15. When the gear 15 rotates, the first rack 11 and the second rack 16 move in opposite directions, thereby facilitating the simultaneous sliding of the limiting block 14 out of the limiting groove formed on the surface of the buckle assembly 7, and thus facilitating the rapid disassembly of the fixing cover 2.

[0026] Further, referring to Figure 3It can be known that rectangular grooves are symmetrically opened on the upper and lower surfaces of the fixed support plate 1. The buckle assembly 7 passes through the rectangular groove and is connected to the limit block 14. A limit groove is opened on the surface of the buckle assembly 7. The buckle assembly 7 passes through the rectangular groove and enters the inside of the fixed support plate 1. The limit block 14 is inserted into the inside of the limit groove, so as to play a role in buckling connection.

[0027] Working principle: When the present utility model is in use, according to the attached Figure 1 , attached Figure 2 , attached Figure 3 and attached Figure 4 shown, first, the fixed support plate 1 is fixedly installed. After installation, the LED digital tube body 4 is inserted into the inside of the fixed cover 2 and limited by the limit strip 3. The fixed cover 2 is sleeved on the surface of the protective cover 9. The rubber pad 8 is pushed by the elastic force of the first spring 10 to be in contact with the surface of the LED digital tube body 4. At this time, the buckle assembly 7 passes through the rectangular groove and is inserted into the inside of the fixed support plate 1. The buckle assembly 7 is connected to the limit block 14, so as to play a role in fixing and limiting;

[0028] After the installation is completed, one hand limits the rubber pad 8, and the other hand rotates the threaded rod 6 clockwise to push the rubber pad 8 to move, so as to limit the connecting wire. When it is necessary to disassemble the buckle assembly 7, rotate the threaded rod 6 counterclockwise, unplug the data cable, and then pull up a set of pull rods 5. The upward movement of the pull rods 5 drives the moving limit plate 12 to move, squeezing the second spring 13 into a contracted state. During the movement of the moving limit plate 12, the first rack 11 is driven to move. The first rack 11 drives the gear 15 to rotate. The rotation of the gear 15 pushes the second rack 16 to move downward. The second rack 16 drives the other set of moving limit plates 12 to move, so as to facilitate the two limit blocks 14 to move away from the inside of the limit groove opened by the buckle assembly 7 at the same time, so as to facilitate disassembly. The operation is completed. The above is the entire working principle of the present utility model.

[0029] In the present utility model, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all its components are its own technologies.
