[0023] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0024] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] See Figure 1 , Figure 2 This is one embodiment of a roof grid connection device according to the present invention.

[0026] The components in this case include a main body 1, a cavity 2 inside the main body 1, and insertion holes around the cavity 2. Insertion blocks 3 are inserted into the insertion holes. One end of the insertion block 3 is connected to a grid support rod 4. A limit block 5 is provided on the lower side inside the cavity 2. A threaded hole is provided on the top of the limit block 5. An opening 6 is provided on the top of the cavity 2. A connecting block 7 is inserted into the opening 6. Insert rods 8 are provided around the bottom of the connecting block 7. The bottom of the insert rods 8 is inserted into the top of the insertion block 3. A rotating cavity 9 is provided on the top of the connecting block 7. A rotating block 10 is provided inside the rotating cavity 9. A threaded rod 11 is connected to the bottom of the rotating block 10. One end of the threaded rod 11 passes through the rotating cavity 9 and is threadedly connected to the threaded hole on the top of the limit block 5. A protective cover 12 is provided on the bottom of the connecting block 7. A notch 13 is provided around the opening 6. The outer perimeter of the protective cover 12 is inserted into the notch 13.

[0027] It should be noted that when the roof net rack is operated, the plug-in block 3 connected with the net rack support rod 4 can be inserted into the insertion hole around the cavity 2, and the plug-in block 3 is tightly attached to the block 17. At this time, the operator can move the connecting block 7 by rotating the handle 16, and the protective cover 12 at the bottom of the connecting block 7 is inserted into the opening 6. At the same time, the protective cover 12 can block rainwater, prevent rainwater from entering the cavity 2, and cause the parts to rust, thereby increasing the service life of the device. At this time, the protective cover 12 outside the four parts is inserted into the notch 13. Then the operator rotates the rotating block 10 in the rotating cavity 9 by rotating the handle 16, and the threaded rod 11 connected with the rotating block 10 is screwed into the threaded hole at the top of the limiting block 5. As the operator continuously rotates the rotating block 10, the connecting block 7 is lowered as a whole, and the plug-in rod 8 at the bottom is inserted into the plug-in block 3 at the top, thereby completing the stable and rapid connection of the plug-in block 3 and the net rack support rod 4 connected with the plug-in block 3. When disassembly is required, the above process is repeated in reverse. The present technical solution improves the connection and disassembly efficiency during assembly, thereby achieving the purpose of increasing work efficiency.

[0028] The rotating cavity 9 is T-shaped, and the shape of the rotating block 10 matches the shape of the rotating cavity 9, preventing the rotating block 10 from falling off.

[0029] A horizontal block 14 is arranged on the upper side of the cavity 2 corresponding to the notch 13. The top of the horizontal block 14 is provided with a spring telescopic rod 15. After the connecting block 7 is completely inserted into the opening 6, the bottom of the connecting block 7 will compress the spring telescopic rod 15 at the top of the horizontal block 14, and the reaction force generated by the compression of the spring telescopic rod 15 will make the connection between the threaded rod 11 and the limiting block 5 more tight, thereby increasing the strength of the device connection.

[0030] A block 17 is arranged on the outer side of the limiting block 5, which is used to limit the position of the plug-in block.

[0031] A base 18 is arranged at the bottom of the main body 1, and fixed bolts are arranged on both sides of the base 18. The operator can fix the base 18 on the building plane according to the use requirement.

[0032] Obviously, the above embodiments are only examples for clear illustration, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments cannot be exhausted, and the obvious changes or variations still fall within the protection scope of the present application.
