Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations set forth in the following description of the specific embodiments.
Example one
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a difficult cracked high strength bolt, includes bolt body 1, and bolt body 1's material is well carbon alloy steel, because bolt body 1's material is well carbon alloy steel, and intensity is higher, and difficult fracture, bolt body 1's top fixed mounting has nut 2, and hexagonal groove 3 has been seted up to nut 2's top surface, and circular slot 4 has been seted up to hexagonal groove 3's inner wall.
Referring to fig. 1-4, a magnet 5 is fixedly mounted on the inner wall of the circular groove 4, the top surface of the magnet 5 is flush with the inner wall of the hexagonal groove 3, the nut 2 is of a hexagonal structure, and the magnet 5 is arranged in the circular groove 4, so that when the nut 2 is screwed by an inner hexagonal wrench, the inner hexagonal wrench can stick to the magnet 5, and at the moment, the magnet 5 can attract the inner hexagonal wrench due to the magnetic force of the magnet 5, so that the screwing can be more convenient, the falling probability of the bolt body 1 in the screwing process is reduced, and the circular groove 4 is the same as the magnet 5 in size.
Example two
Referring to fig. 2, the bottom surface of the nut 2 is provided with the anti-loosening mechanisms near the edge, the anti-loosening mechanisms include three sets of spacers 6, the spacers 6 are fixedly mounted on the bottom surface of the nut 2 near the edge, the number of the anti-loosening mechanisms is three, the three sets of anti-loosening mechanisms are arranged on the bottom surface of the nut 2 in a circumferential manner, the bottom surface of the spacer 6 is fixedly provided with the triangular block 7, the triangular block 7 is made of natural rubber or nitrile rubber, and the triangular block 7 is made of natural rubber or nitrile rubber and is relatively soft, so that when the nut 2 and the bolt body 1 are attached to the mounting surface, a relatively large friction force can be generated, the probability of loosening of the nut 2 and the bolt body 1 is further reduced, and the bolt body 1 is guaranteed to be fixedly and stably fixed.
