Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1-2, a fastener includes: a bolt head 11 and a screw 12 fixed at one end of the bolt head; the screw rod is provided with threads 121; the screw rod is also provided with three nylon coatings 13 which are uniformly distributed in the circumferential direction. Specifically, the nylon coating may be oval in shape. Specifically, the width of the nylon coating layer along the circumferential direction of the screw corresponds to a central angle of 60 ° to 80 °. In one embodiment, the nylon coating has a length along the axial direction of the screw of 0.2cm to 2 cm. Preferably, the nylon coating is located at an end of the screw remote from the bolt head.
In order to facilitate the rotation of the bolt head, the end of the bolt head remote from the threaded rod is provided with a slot. The open groove can be a straight groove, a cross groove, a plum blossom groove, an inner hexagonal groove, a square groove, a triangular groove or a Y-shaped groove. That is, the application does not limit the specific shape of the slot.
Based on the same inventive concept, the application also provides a fastener, which comprises a screw rod; the screw rod is provided with threads; the screw is also provided with three nylon coatings which are uniformly distributed in the circumferential direction; one end of the screw rod is provided with a slot. That is, a structure of a headless bolt is provided. Preferably, the nylon coating may be located at an end of the screw remote from the slot.
The open groove can be a straight groove, a cross groove, a plum blossom groove, an inner hexagonal groove, a square groove, a triangular groove or a Y-shaped groove. That is, the application does not limit the specific shape of the slot.
The utility model has the advantages that:
not only can play a certain sealed effect, but also can play a certain anti-loosening effect. Specifically, three nylon coatings evenly distributed in the circumferential direction can increase the sealing effect and enhance the anti-loosening effect.
The following table gives the relevant test results:
the above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
