[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1 A structural diagram of a preferred embodiment of a reinforced stainless steel fastener provided by the utility model; Figure 2 for Figure 1 A structural diagram of the threaded rod structure shown; Figure 3 for Figure 1 A schematic structural diagram of the rubber ring structure shown; Figure 4 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 5 for Figure 2 The enlarged schematic diagram of part B is shown. The reinforced stainless steel fastener includes: a hexagonal fixing block 1, the bottom of which is rotatably connected to a disc 4, a threaded rod 3 fixedly installed at the center of the bottom of the hexagonal fixing block 1, the threaded rod 3 passing through the disc 4, a nut 2 threadedly connected to the outer wall of the lower end of the threaded rod 3, and a plurality of groups of bar blocks 9 installed on the top of the disc 4. Each group of bar blocks 9 has a rectangular groove 2 13 formed on the top, and each group of rectangular groove 2 13 is fixedly connected to a rotating shaft 19 on the inner wall near the hexagonal fixing block 1. Each group of rotating shaft 19 is rotatably connected to a rectangular rod 17 on the outer wall. The side walls of the hexagonal fixing block 1 are each mounted with rectangular blocks 5, each group of rectangular blocks 5 has a rectangular groove 10 formed on the side near the rectangular groove 2 13, and each group of rectangular blocks 5 has a limit assembly 8 installed on the side wall, and the limit assembly 8 contacts the outer wall of the rectangular rod 17.

[0023] The limiting assembly 8 includes a limiting hole 83, which is opened on the side wall of the rectangular block 5 at the entrance end of the rectangular slot 10. The limiting hole 83 runs through the entire rectangular block 5. A limiting rod 84 is connected to the inside of the limiting hole 83. The limiting rod 84 is located at the outer end of the rectangular block 5 and is equipped with a handle 81. A spring 82 is installed between the handle 81 and the outer wall of the rectangular block 5. The spring 82 is sleeved on the outside of the limiting rod 84. When the handle 81 is pulled outward, the handle 81 drives the limiting rod 84 to leave the limiting hole 83, thereby releasing the blockage of the entrance end of the rectangular slot 10. When the handle 81 is released, the spring 82 will automatically drive the limiting rod 84 to reset, so that the limiting rod 84 can re-block the entrance end of the rectangular slot 10.

[0024] A torsion spring 18 is provided at the connection between the rotating shaft 19 and the rectangular rod 17. The setting of the torsion spring 18 ensures that when the limit rod 84 no longer blocks the entrance end of the rectangular groove 10, the rectangular rod 17 automatically enters the rectangular groove 2 13 from the inside of the rectangular groove 10 under the action of the torsion spring 18.

[0025] A hexagonal groove 6 is provided on the top of the hexagonal fixing block 1 , and a cross groove 7 is provided on the bottom of the hexagonal groove 6 . The arrangement of the hexagonal groove 6 and the cross groove 7 allows the hexagonal fixing block 1 to be rotated by using corresponding tools.

[0026] An annular groove 12 is formed on the top of the nut 2 , and a rubber ring 11 is placed on the inner wall of the annular groove 12 . The provision of the rubber ring 11 increases the friction between the nut 2 and the object to be fastened.

[0027] The rubber ring 11 is composed of a vulcanized butadiene rubber layer 14, a chloroprene rubber layer 15 and an isoprene rubber layer 16. The vulcanized butadiene rubber layer 14 is located on top of the chloroprene rubber layer 15 and is fixedly connected by gluing. The bottom of the chloroprene rubber layer 15 is fixedly connected to the top of the isoprene rubber layer 16. The arrangement of the vulcanized butadiene rubber layer 14 makes the vulcanized butadiene rubber have particularly excellent cold resistance, wear resistance and elasticity. The arrangement of the chloroprene rubber layer 15 makes the rubber ring have good comprehensive performance and is resistant to oil, flame, oxidation and ozone.

[0028] The working principle of the reinforced stainless steel fastener provided by the present invention is as follows: the threaded rod 3 is passed through the object to be fastened, and then the nut 2 is put onto the outside of the threaded rod 3 and tightened, so that the object to be fastened is fixed between the nut 2 and the disc 4, and then the rectangular rod 17 is rotated a certain angle from the inside of the rectangular groove 2 13, and then the rectangular groove 10 is opened by the limiting component 8, and the rectangular rod 17 is pushed into the inside of the rectangular groove 10, and then the entry end of the rectangular groove 10 is closed by the limiting component 8, so that one end of the rectangular rod 17 is locked inside the rectangular groove 10, and the other end is restricted inside the rectangular groove 2 13, thereby forming a lock to prevent the hexagonal fixing block 1 from being displaced during use.

[0029] Compared with the related art, the reinforced stainless steel fastener provided by the present invention has the following advantages:

[0030] Beneficial effects:

[0031] Through the interaction of components such as the nut 2, threaded rod 3, disc 4, rectangular rod 17, rectangular slot 2 13, limit assembly 8, rectangular slot 1 10 and hexagonal fixing block 1, the hexagonal fixing block 1 can be reinforced to prevent the hexagonal fixing block 1 from being displaced during use and causing the threaded rod 3 and nut 2 to loosen.
