Problems solved by technology
However, in the existing threaded assembly, the inner end faces of the nut and the end of the bolt are all set to a planar structure, and the inner end face of the planar structure is a simple smooth surface, and there is no gap between it and the contact surface of the assembled object. With anti-loose anti-slip resistance
Therefore, when the relevant parts vibrate and transmit between the screwed assembly and the assembled object, because the existing screwed assembly does not have an effective anti-loosening and anti-slip structure, it will be damaged in the existing screwed assembly and the assembled object over time. loose sliding

Embodiment Construction
[0033] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with accompanying drawings.
[0034] Please refer to the attached figure 1 to attach image 3 Shown is an embodiment of the bolt 100 of the anti-loosening and anti-slip screw assembly of the present invention, which includes an end body 110 and a rod body 120 integrally formed, and further includes a connecting piece 130 .
[0035] The end body 110 has a first outer end surface 111 and a first inner end surface 112 opposite to each other. Wherein, the first inner end surface 112 is provided with several first protruding teeth 113, which extend radially from the first central portion 114 of the first inner end surface 112 to the first outer peripheral portion 115 of the first inner end surface 112 at intervals. , and several first protruding teeth 113 protrude obliquely in a helical shape towar...

The invention discloses an anti-loosening and anti-slip screw assembly and its bolts and nuts. The anti-loosening and anti-slip screw assembly includes a bolt and a nut. The bolt includes an end body and a rod body integrally formed, the inner end surface of the end body is provided with a plurality of first protruding teeth, and the rod body is provided with a thick diameter portion. The nut includes an end plate, a screw body and a screw hole integrally formed, and a plurality of second protruding teeth are arranged on the inner end surface of the end plate. The plurality of first protruding teeth and the plurality of second protruding teeth provided on the bolt and the nut have anti-loosening and anti-slip functions, and the thick-diameter portion provided on the bolt can improve the torsion resistance strength of the bolt.
Description
technical field [0001] The invention relates to a nut combination, in particular to an anti-loosening and anti-slip screw assembly and its bolts and nuts. Background technique [0002] The screwing method is a feasible method for assembling objects, and its advantage is that it is easy to assemble. The screwing method is realized by screwing components. The threaded assembly usually includes a bolt with an external thread, and a nut with an internal thread corresponding to the external thread of the bolt. The inner end surface of the bolt end and the inner end surface of the nut are jointly pressed to assemble the assembled object. [0003] In actual use, due to the vibration of related parts or other factors, sometimes there will be a phenomenon of loosening and sliding between adjacent surfaces of different parts. For example, loose sliding occurs between the inner end surface of the nut and the assembled object, and between the inner end surface of the bolt end and the...
