[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] See also Figure 1-4A self-locking fastening bolt comprises a body 1, a slot 2 is provided on the outer wall of the body 1, a nut 3 is threadedly connected to the outer wall of the body 1, a mounting hole 6 is provided in the middle of the nut 3, a movable hole 9 is provided on the inner wall of the mounting hole 6, a through slot 4 is provided on the inner wall of the movable hole 9, a retaining ring 7 is sleeved on the inner wall of the mounting hole 6, a retaining rod 10 is abutted on the outer wall of the retaining ring 7, a ferrule 8 is fixedly sleeved on the outer wall of the retaining rod 10, and a force block 5 is fixedly assembled on the outer wall of the ferrule 8.

[0021] In the above structure, by setting the main body 1, the slot 2, the nut 3, the through slot 4, and the clamping rod 10 structure, when the fastening bolt is in use, when the user connects the main body 1 with the nut 3, the clamping rod 10 is ejected by utilizing the elasticity of the retaining spring 7, so that the clamping rod 10 is plugged into the slot 2, thereby achieving the effect of locking the main body 1, thereby improving the stability of the main body 1 after installation.

[0022] In a preferred embodiment, the inner wall of the through slot 4 is slidably connected to the outer wall of the force-bearing block 5 , there are two force-bearing blocks 5 , and the two force-bearing blocks 5 are symmetrically distributed along the bottom of the nut 3 .

[0023] In the above structure, through the provided nut 3 and force block 5 structure, when the user connects the nut 3 with the main body 1, the force block 5 can be pried to allow the clamping rod 10 to disengage from the clamping slot 2, thereby facilitating the user to continue rotating and making the nut 3 and the main body 1 connected more tightly, further improving the stability of the fastening bolt after assembly, and also making it convenient for the user to remove the clamping rod 10 and separate the main body 1 and the nut 3, thereby improving the user's disassembly and assembly efficiency of the fastening bolt.

[0024] In a preferred embodiment, the outer wall of the ferrule 8 is slidably connected to the inner wall of the movable hole 9, and the ferrule 8 is made of galvanized iron metal.

[0025] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the ring 8 during movement, thereby extending the service life of the ring 8. At the same time, it can also ensure the limiting effect of the ring 8 on the clamping rod 10, thereby improving the stability of the fastening bolt after long-term use.

[0026] In a preferred embodiment, the number of the card slots 2 is four, and the four card slots 2 are evenly distributed along the outer wall of the body 1 .

[0027] In the above structure, by setting up four slots 2, when the user rotates the nut 3, the two slots 2 can be used to lock the main body 1, avoiding the main body 1 from being blocked by the clamping rod 10 due to errors in the production process and thus being unable to be locked, thereby ensuring the normal use of the fastening bolt.

[0028] In a preferred embodiment, the interior of the mounting hole 6 is communicated with the inner wall of the nut 3 through the movable hole 9 , and a circular hole is formed on the inner wall of the movable hole 9 , and the diameter of the circular hole matches the diameter of the clamping rod 10 .

[0029] In the above structure, the circular hole structure is provided so that the card rod 10 can be inserted into the card slot 2 when it pops out, so that the body 1 is restricted and cannot rotate, thereby achieving a self-locking effect, ensuring the stability of the body 1 after installation and preventing it from loosening.

[0030] In a preferred embodiment, the diameter of the clamping groove 2 is matched to the diameter of the clamping rod 10 .

[0031] In the above structure, the slot 2 structure is provided, and the slot 2 can accommodate the clamping rod 10, thereby ensuring that the main body 1 can be fixed and cannot rotate, avoiding the main body 1 from loosening due to vibration or external force after installation, and improving the stability of the fastening bolt.

[0032] Working principle: After the user connects the main body 1 with the nut 3, he rotates the nut 3 and at the same time presses the force block 5 with a single finger so that the force block 5 cannot push the clamping rod 10 to pop out, thereby ensuring that the nut 3 can continue to rotate until it is fixedly connected to the main body 1, so that the main body 1 can fix the equipment or installation component. After tightening, the user can loosen the force block 5, so that the force block 5 automatically pops out due to the elasticity of the retaining spring 7 and is plugged into the clamping slot 2, so that there is no positional offset between the main body 1 and the nut 3, thereby achieving a self-locking effect. If the fastening bolt needs to be disassembled, the nut 3 can be rotated in the opposite direction through the same steps as above.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
