Problems solved by technology
Bolts are also widely used in automobiles. It can be said that a car is inseparable from bolts, but various vibrations will occur during driving, which will have a certain impact on bolts. The existing bolts have a simple structure. Under the influence of long-term vibration, the bolts may be loosened, resulting in damage to parts, and even serious car accidents

The invention discloses a high-strength anti-loosening bolt with a hexagonal flange surface for automobiles, which comprises a screw body, a screw head, a flange plate, and several anti-loosening clips. The screw body is cylindrical, and the outer surface of the screw body is The outer thread of the screw is coiled, and the upper end of the screw body is provided with a screw head that can cooperate with it. The screw head and the screw body are coaxially arranged, and a flange is provided between the screw head and the screw body. The flange is arranged coaxially with the screw body and the screw head, and a number of anti-loosening clips are arranged inside the upper end of the screw body. distance setting, the present invention arranges a number of anti-loosening clips between the upper end of the bolt and the flange, and the bolt can be clamped after the bolt is tightened, the friction between the bolt and the screw hole is improved, the anti-loosening performance of the bolt is improved, and the bolt is increased. safety.
Description
【Technical field】 [0001] The invention relates to the technical field of bolts, in particular to the technical field of anti-loosening bolts on automobile hexagonal flange surfaces. 【Background technique】 [0002] Bolt is the physical and mathematical principle of using the oblique circular rotation and friction of the object to tighten the device parts step by step. Bolt is a general term for fasteners, and it is an everyday colloquial language. Bolt is an indispensable industrial necessity in daily life: the tiny bolt used in cameras, glasses, clocks, electronics, etc.; the general bolts for TV, electrical products, Musical Instruments, furniture, etc.; Bolts and nuts; vehicles, airplanes, trams, automobiles, etc. are used in combination with large and small bolts. Vital task industrially born by bolt, as long as there is industry on the earth, then the function of bolt will be the most important forever. Bolt is a common invention in people's production and life for th...
