[0018] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0019] Example
[0020] like Figures 1 to 6 The tight anti-dropping washer bolt of the utility model comprises a bolt body, a corrugated washer 4 and a positioning buckle 5, which are both sleeved on the bolt body, and the positioning buckle 5 is used to fix the corrugated washer 4; when the bolt body is in use, the corrugated washer 4 is fixed by the positioning buckle 5, which increases the stability of the corrugated washer 4 during use, prevents the corrugated washer 4 from loosening on the head 1, and improves the reliability and practicality during use.
[0021] like Figure 1 and Figure 3 The bolt body includes a head 1, a connecting part 2 and a rod 3. The connecting part 2 is fixedly installed at the lower end of the head 1, and the rod 3 is fixedly installed at the lower end of the connecting part 2. The diameter of the rod 3 is larger than the diameter of the connecting part 2. The corrugated washer 4 and the positioning buckle 5 are both provided with circular holes communicating with each other from top to bottom. The diameter of the circular holes is smaller than the diameter of the rod 3. The corrugated washer 4 and the positioning buckle 5 are both mounted on the connecting part 2. Since the diameters of the circular holes on the corrugated washer 4 and the positioning buckle 5 are smaller than the diameter of the rod 3, and the corrugated washer 4 and the positioning buckle 5 are both mounted on the connecting part 2, the corrugated washer 4 and the positioning buckle 5 are not easy to fall off on the connecting part 2, which is convenient for use.
[0022] like Figure 4 The upper and lower end surfaces of the corrugated washer 4 are both wavy, and a plurality of groups of protrusions 6 are arranged on the upper circumference of the positioning buckle 5, and the plurality of groups of protrusions 6 are fixedly mounted on the upper end of the positioning buckle 5, and the plurality of groups of recesses on the wavy shape on the lower end surface of the corrugated washer 4 are respectively located directly above the plurality of groups of protrusions 6; through the above arrangement, when the bolt body is fastened to the fastener, pressure is applied to the corrugated washer 4 and the positioning buckle 5 by the head 1 and the fastener respectively, so that the corrugated washer 4 and the positioning buckle 5 are squeezed against each other, so that the plurality of groups of protrusions 6 on the upper end of the positioning buckle 5 are respectively tightened and fixed with the plurality of groups of recesses on the lower end surface of the corrugated washer 4, so that the corrugated washer 4 and the positioning buckle 5 are engaged with each other, thereby improving the stability of the corrugated washer 4 during use and preventing the corrugated washer 4 from slipping, having a simple structure and good anti-loosening effect.
[0023] like Figure 6 The lower end of the positioning buckle 5 is provided with multiple groups of circular grooves 7, and the multiple groups of circular grooves 7 are evenly distributed on the circumference of the lower end of the corrugated washer 4; through the above arrangement, when the bolt body is connected with the counterpart, the lower end surface of the positioning buckle 5 is in close contact with the counterpart. Since the circular grooves 7 are provided on the positioning buckle 5, the positioning buckle 5 can be fixedly adsorbed on the counterpart while being in close contact with the counterpart, preventing the positioning buckle 5 from slipping and ensuring the interference positioning effect of the positioning buckle 5 on the corrugated washer 4. It is easy to use and has high reliability.
[0024] Soft pads are arranged in the multiple groups of circular grooves 7 .
[0025] like Figure 2 A polygonal groove 9 is provided at the upper end of the head 1; through the above arrangement, a wrench can be inserted into the polygonal groove 9 to rotate the head 1 of the bolt body, which facilitates the rotation of the bolt body and improves convenience.
