To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-loosening bolt with a nylon column, comprising a bolt head, a connecting section, a bolt rod, a bolt side hole, and a nylon column, wherein a connecting section is provided downward from the center of the bolt head, the diameter of the bolt head is larger than the diameter of the connecting section, the lower end of the connecting section is connected to the bolt rod, a bolt side hole is provided on the outer side of the bolt rod, and a nylon column is provided inside the bolt side hole.

Preferably, the bolt head is a hexagonal bolt head.

Preferably, the connecting section is cylindrical.

Preferably, the bolt rod is provided with an external thread on the outside, and the external thread is spirally arranged on the outside of the bolt rod.

Preferably, the bolt rod and the connecting section have the same diameter.

Preferably, the bolt side hole is arranged on the side of the bolt rod close to the bottom, the bolt side hole is a hollow cylindrical shape, and the inner wall of the bolt side hole is provided with a thread.

Preferably, the nylon column comprises a nylon column head and a nylon rod, the lower part of the nylon column head is connected to the nylon rod, and the nylon rod is provided with a spiral thread.

Preferably, the nylon column is detachably mounted inside the bolt side hole on the bolt rod.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a kind of anti-loosening bolt with a nylon column, the bolt side hole is provided with a nylon column, when the bolt is tightened, the nylon column can provide additional friction and increase the anti-loosening ability; the nylon column can reduce the vibration of the structural parts and improve the connection stability of the bolt; the anti-loosening bolt adopts the bolt side hole design to make the installation faster and easier, and the installation can be completed by simply inserting the nylon column into the side hole, and the installation is convenient and quick.

DETAILED DESCRIPTION

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.

Referring to Figures 1-3, in the embodiment of the utility model, a locking bolt with a nylon column includes a bolt head 1, a connecting section 2, a bolt rod 3, a bolt side hole 4, and a nylon column 5. The center of the bolt head 1 is provided with a connecting section 2 downward, the bolt head 1 is an external hexagonal bolt head, the connecting section 2 is cylindrical, the diameter of the bolt head 1 is larger than the diameter of the connecting section 2, the lower end of the connecting section 2 is connected to the bolt rod 3, the bolt rod 3 has the same diameter as the connecting section 2, a bolt side hole 4 is provided on the outer side of the bolt rod 3, and a nylon column 5 is provided inside the bolt side hole 4.
