The invention relates to a fastener structure, in particular to a locking bolt having a fine positioning function and capable of being prevented from being loosened by utilizing blockage of a mechanical body. The locking bolt comprises a nut, a screw rod and an elastic locking pin, wherein an annular column body is arranged at one end of the nut; through holes distributed in a radial direction and perpendicular to an axis are uniformly formed in the side surfaces of the annular column body; a thread matched with the nut is formed in the surface of the screw rod; two notches are axially formed in parallel in the side surfaces of the screw rod; the elastic locking pin consists of a pin rod and an elastic ring, and the front and back surfaces of the elastic locking pin are marked; the elastic ring is arranged along the annular column body of the nut; one side of the elastic ring is bent inwards and can be inserted in the through hole of the nut; the pin rod is arranged on the other side of the elastic ring; the diameter of the pin rod is slightly smaller than the diameter of the through hole of the nut; and the pin rod can penetrate through the through hole of the nut and is positioned in the notch of the screw rod. The bolt is short in usage process and convenient and quick to operate. The whole bolt is simple in structure and the elastic locking pin can be inserted and clamped on the nut when not in use and is stored together with the nut, so that the locking bolt is very convenient to tidy and collect.
Description
technical field [0001] The invention relates to a fastener structure, in particular to a fine positioning locking bolt which uses a mechanical body to prevent the bolt from loosening. Background technique [0002] Bolt connection is a commonly used mechanical connection method, which has the advantages of repeated disassembly and assembly and easy maintenance. But the bolt connection also has an obvious disadvantage, that is, it is easy to loosen. The relative rotation between the nut and the screw is easy to cause the bolt to loosen, especially the vibration can cause the bolt to loosen. In order to prevent the bolts from loosening, there are two commonly used methods to solve the problem: [0003] The first category is to use various friction forces to prevent bolts from loosening. Most of the anti-loosening bolts, anti-skid bolts, and locking bolts adopt various structures on the nuts, screws or bolts to prevent the bolts from loosening by various forms of friction. T...
