In the figure: the bolt comprises a bolt column 1, an inner bolt head 2, an outer bolt head 3, a square hole 4, a locking gasket 5, a plum blossom-shaped inner hole 6, a hexagonal prism 7, an anti-skid thorn 8 and a thread groove 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an inner hole type bolt with good anti-slip effect comprises a bolt column 1, wherein the top of the bolt column 1 is connected with an inner screw head 2, the inner screw head 2 is fixed at the top of the bolt column 1 in a welding mode to ensure the strength of the inner screw head 2 and further increase the mutual stability between the inner screw head 2 and the bolt column 1, the outer screw head 3 is sleeved outside the inner screw head 2, the outer screw head 3 is clamped outside the inner screw head 2 through a square hole 4, the bottom of the outer screw head 3 is provided with a square hole 4, a locking gasket 5 is sleeved on the bolt column 1 inside the square hole 4, the locking gasket 5 has elasticity, the bolt column 1 can be prevented from loosening from a connecting structure through the elastic locking gasket 5, the main function of the inner hole type bolt is that the locking gasket 5 plays a role of reacting force, when the outer screw head 3 is extruded by external force, the locking gasket 5 is extruded to deform, the deformed locking gasket 5 generates reacting force to weaken the external force, the bolt column 1 can be effectively prevented from being pulled by external force to be loosened, the top of the outer screw head 3 is provided with the plum blossom-shaped inner hole 6, the plum blossom-shaped inner hole 6 and the hexagonal prism 7 are formed on the outer screw head 3 in a die-casting mode, the hexagonal prism 7 and the outer screw head 3 are integrally arranged, the strength of the hexagonal prism 7 can be effectively guaranteed, the stability of the hexagonal prism 7 is improved, the hexagonal prism 7 is connected to the top of the outer screw head 3 positioned in the plum blossom-shaped inner hole 6, the bottom of the outer screw head 3 is provided with the anti-skid spines 8, the anti-skid spines 8 are manufactured in a die-casting mode, and the bottom of the outer screw head 3 can play a role in skid resistance;

It is specific, fix bolt cooperation nut on treating the connecting piece through specific spanner, when using the spanner to twist the bolt, the spanner inserts in the plum blossom hole 6, the inside hexagonal clamping groove card of spanner is established on hexagonal prism 7, can effectually avoid spanner and the outer bolt head 3 of bolt to produce and slide, and then avoid the outer bolt head 3 of bolt to damage, bolt fixed connection accomplishes the back, when the bolt is dragged to external force, the check washer 5 at 1 top of bolt post is by extrusion deformation, and then 5 production reaction forces of check washer weaken external force and neutralize, and then can prevent the bolt looseness.
