Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Please refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: A bolt fastener includes a first fastening plate 1 and a second fastening plate 2. The lower end surface of the first fastening plate 1 is provided with the second fastening plate 2. A connection sleeve bolt 4 is fixedly installed inside the first fastening plate 1 and the second fastening plate 2. A second gasket 6 is provided between the connection sleeve bolt 4 and the second fastening plate 2. A sealing ring 11 is provided at the upper end of the connection sleeve bolt 4. A positioning connection sleeve 3 is installed inside the sealing ring 11. A first gasket 5 is provided between the positioning connection sleeve 3 and the first fastening plate 1. Two limit clamping rings 15 and a connection ring 16 are provided between the connection sleeve bolt 4 and the positioning connection sleeve 3. The connection sleeve bolt 4 is fixedly welded to the two limit clamping rings 15, and the positioning connection sleeve 3 is fixedly welded to the two connection rings 16. The limit clamping ring 15 and the connection ring 16 are snap-fitted and installed, and the positioning connection sleeve 3 and the connection sleeve bolt 4 are limited and locked by the limit clamping ring 15 and the connection ring 16.

[0021] Please refer to Figure 2 , a locking bolt 7 is installed inside the positioning connection sleeve 3. The bottom end of the positioning connection sleeve 3 penetrates through the sealing ring 11 and is inserted into the inside of the connection sleeve bolt 4. The bottom end of the locking bolt 7 penetrates through the positioning connection sleeve 3 and is threadedly connected to the connection sleeve bolt 4. The positioning connection sleeve 3 and the first fastening plate 1 are connected through the sealing ring 11. The sealing ring 11 can continuously seal the limit clamping ring 15 and the connection ring 16.

[0022] Please refer to Figure 1 and Figure 3, a transparent sealing piece 8 is installed inside the upper end of the locking bolt 7. An elastic shielding seat 10 is movably installed on the lower end surface of the transparent sealing piece 8. A fluorescent ring 9 is slidably connected to the outside of the elastic shielding seat 10. A transmission rod 12 is installed at the bottom end of the elastic shielding seat 10. A connecting rod 13 is installed at the bottom end of the transmission rod 12. A rubber seat 14 is provided between the transmission rod 12 and the connecting rod 13. Both the transparent sealing piece 8 and the fluorescent ring 9 are adhesively fixed to the locking bolt 7. The upper end of the elastic shielding seat 10 is inserted into the inside of the transparent sealing piece 8 and the fluorescent ring 9. The bottom end of the elastic shielding seat 10 is adhesively fixed to the transmission rod 12. The upper end of the connecting rod 13 penetrates through the connecting sleeve bolt 4 and is inserted into the inside of the locking bolt 7.

The connecting rod 13 and the connecting sleeve bolt 4 are threadedly connected. By gradually reducing the shielding area of the fluorescent ring 9 by the elastic shielding seat 10, the brightness of the fluorescent ring 9 can be observed, and thus the loosening condition of the bolt fastener can be quickly judged.

[0023] During use, insert the connecting sleeve bolt 4 into the inside of the first fastening plate 1 and the second fastening plate 2. At this time, insert the positioning connecting sleeve 3 into the inside of the connecting sleeve bolt 4 and rotate it by a certain angle, so that the positioning connecting sleeve 3 and the connecting sleeve bolt 4 are clamped and installed through the limit retaining ring 15 and the connecting ring 16. Pass the bottom end of the locking bolt 7 through the positioning connecting sleeve 3 and threadedly connect it with the connecting sleeve bolt 4, so that the fixing and locking operation of the first fastening plate 1 and the second fastening plate 2 can be realized by connecting the connecting sleeve bolt 4 and the locking bolt 7. On the basis of the limit connection of the positioning connecting sleeve 3 and the connecting sleeve bolt 4 by the limit retaining ring 15 and the connecting ring 16, further locking is carried out through the locking bolt 7, which can effectively maintain the fixing effect of the whole on the first fastening plate 1 and the second fastening plate 2;

[0024] The transparent sealing piece 8 and the fluorescent ring 9 are adhesively bonded inside the upper end of the locking bolt 7, and the upper end of the elastic shielding seat 10 is inserted between the transparent sealing piece 8 and the fluorescent ring 9. The bottom end of the elastic shielding seat 10 is fixed to the transmission rod 12. The upper end of the connecting rod 13 penetrates through the connecting sleeve bolt 4 and is fixedly connected to the transmission rod 12 through the rubber seat 14. When loosening occurs during the overall application process, the connecting rod 13 drives the transmission rod 12 to move downward through the rubber seat 14 under the supporting action of the connecting sleeve bolt 4, so that the transmission rod 12 drives the elastic shielding seat 10 to slide inside the locking bolt 7. Furthermore, the shielding area of the elastic shielding seat 10 for the fluorescent ring 9 gradually decreases, so that the fluorescent ring 9 gradually becomes brighter in a dim environment. The loosening condition of the whole can be directly observed in real time through the brightness of the fluorescent ring 9, which is convenient for timely maintenance and replacement.
