Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-6A splicing structure of an LED display screen 8 includes a main body 1, a position adjustment mechanism and a quick installation mechanism, the position adjustment mechanism includes a mounting frame 2, a fastening bolt 3, a support plate 4, a butterfly nut 5 and a sliding rod 6, the mounting frame 2 is detachably connected to the main body 1 through the fastening bolt 3, the support plate 4 is installed inside the mounting frame 2 and slides inside the mounting frame 2, the sliding rod 6 is fixedly installed at both ends of the support plate 4 and slides inside the mounting frame 2, the butterfly nut 5 is detachably connected to the sliding rod 6, the quick connection mechanism includes a connecting rod 7, a display screen 8, an extrusion block 9, a first spring 10 and a clamping mechanism, the connecting rod 7 is detachably connected to the display screen 8, the extrusion block 9 is installed inside the support plate 4, the first spring 10 is installed inside the support plate 4 and the two ends are respectively fixedly connected to the extrusion block 9 and the support plate 4.

[0030] In this embodiment, the position adjustment mechanism includes a mounting frame 2, a fastening bolt 3, a support plate 4, a butterfly nut 5 and a sliding rod 6. When in use, the end face of the mounting frame 2 is aligned with the main body 1, and then the fastening bolt 3 is inserted into the mounting hole 20 to complete the fixation of the main body 1 and the mounting frame 2. Then, according to the position and size of the display screen 8, the position of the support plate 4 is adjusted, and the sliding rod 6 is pushed to slide inside the adjustment groove 14. After reaching the specified position, the butterfly nut 5 is installed on the sliding rod 6 and then tightened to make the butterfly nut 5 move on the sliding rod 6. When the butterfly nut 5 touches the mounting frame 2 and is squeezed and fixed, the position adjustment is completed and the display screen 8 is placed.

[0031] In this embodiment, the quick connection mechanism includes a connecting rod 7, a display screen 8, an extrusion block 9, a first spring 10 and a clamping mechanism. When in use, after aligning the connecting rod 7 on the display screen 8 with the insertion hole 21 on the support plate 4, the display screen 8 is pressed inwardly. During this process, the clamping head 18 on the connecting rod 7 enters the insertion hole 21 and begins to contact the extrusion block 9. As the pressure is pressed, the limit block 16 on the extrusion block 9 slides in the limit groove in the insertion hole 21 and contacts the clamping block 12, extruding the clamping block 12 into the support plate 4 and starting to compress the first spring 10. When the limit block 16 slides to the bottom of the limit slide groove 15, the clamping mechanism works at this time to fix the clamping head 18 in the insertion hole 21. When the display screen 8 needs to be repaired or replaced, the clamping mechanism is moved, and the clamping head 18 is no longer bound. At this time, the first spring 10 pops outward to give the extrusion block 9 a pop-up force, thereby popping out the clamping head 18 and removing the display screen 8.

[0032] In this embodiment, the clamping mechanism includes a second spring 11, a clamping block 12 and a push-pull rod 13. When in use, when the clamping head 18 reaches the position of the clamping mechanism, the clamping block 12 is no longer squeezed by the extrusion block 9. The compressed second spring 11 begins to exert force on the clamping block 12 and pops the clamping block 12 out and inserts it into the clamping hole 19 inside the clamping head 18. At this time, the push-pull rod 13 slides inside the push-pull slide groove 17 under the drive of the clamping block 12. At this time, the clamping block 12 is in the clamping hole 19, and the first spring 10 exerts force to push the extrusion block 9, and the extrusion block 9 squeezes the clamping head 18 again, so that; the clamping head 18 is subjected to vertical force to form a static state. According to the above-mentioned contact clamping state, the push-pull rod 13 is pushed and pulled toward the middle part of the support plate 4. At this time, the clamping block 12 is disengaged from the clamping hole 19, and the clamping head 18 leaves the support plate 4 under the action of the extrusion plate.

[0033] Embodiment 2:

[0034] In summary, when in use, the end face of the mounting frame 2 needs to be aligned with the main body 1, and then the fastening bolts 3 are inserted into the mounting holes 20 to complete the fixation of the main body 1 and the mounting frame 2. Then, according to the position and size of the display screen 8, the position of the support plate 4 is adjusted, and the sliding rod 6 is pushed to slide inside the adjustment slot 14. After reaching the specified position, the butterfly nut 5 is installed on the sliding rod 6 and then tightened to make the butterfly nut 5 move on the sliding rod 6. When the butterfly nut 5 touches the mounting frame 2 and is squeezed and fixed, the installation is completed. After the position is adjusted, the display screen 8 is placed. When the support plate 4 is fixed, the display screen 8 is installed. After the connecting rod 7 on the display screen 8 is aligned with the insertion hole 21 on the support plate 4, the display screen 8 is pressed inward. During this process, the clamping head 18 on the connecting rod 7 enters the insertion hole 21 and begins to contact the extrusion block 9. As the pressure is pressed, the limit block 16 on the extrusion block 9 slides in the limit groove in the insertion hole 21 and contacts the clamping block 12, which is squeezed into the support plate 4 and the first spring begins to be compressed. 10. When the limit block 16 slides to the bottom of the limit slot 15 and the clamping head 18 reaches the position of the clamping mechanism, the clamping block 12 is no longer squeezed by the squeezing block 9. The compressed second spring 11 starts to exert force on the clamping block 12 and pops the clamping block 12 out and inserts it into the clamping hole 19 inside the clamping head 18. At this time, the push-pull rod 13 slides inside the push-pull slot 17 driven by the clamping block 12. At this time, the clamping block 12 is in the clamping hole 19, and the first spring 10 pushes the squeezing block 9 to squeeze. Block 9 squeezes the clamping head 18 again, so that the clamping head 18 is subjected to vertical force and forms a static state. When the display screen 8 needs to be repaired or replaced, the clamping mechanism needs to be released. At this time, the push-pull rod 13 is pushed and pulled toward the middle part of the support plate 4. At this time, the clamping block 12 is disengaged from the clamping hole 19, and the clamping head 18 leaves the support plate 4 under the action of the squeezing plate. The clamping head 18 is no longer restrained. At this time, the first spring 10 pops outward to give the squeezing block 9 a pop-out force, thereby popping out the clamping head 18 and removing the display screen 8.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
