[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4As shown, this utility model provides an anti-loosening screw, including: a head 1, the lower surface of the head 1 is fixedly connected to the connecting part 5 through the positioning part 4, and the outer side of the positioning part 4 is symmetrically provided with positioning grooves 10, and the inner side of the check ring 7 is connected to the positioning block 13 corresponding to the position of the positioning groove 10. The upper surface of the check ring 7 is fixedly connected to the lower surface of the head 1, and the lower surface of the check ring 7 is symmetrically provided with check grooves 6. At the same time, the fastening pad 2 is sleeved on the outer side of the positioning part 4, and the lower surface of the fastening pad 2 is provided with adhesive grooves 8 and adsorption grooves 3 respectively, and the upper surface of the fastening pad 2 is provided with buffer grooves. The bottom of the buffer grooves is symmetrically provided with through holes, and the fixing ring 11 is slidably connected in the buffer grooves. The lower surface of the fixing ring 11 is connected to the fitting rod 9 corresponding to the position of the through hole.

[0019] In this embodiment, when using anti-loosening screws to fix objects, first, the fastening washer 2 is fitted onto the positioning part 4 of the screw, and then the connecting part 5 of the screw is passed through the through hole of the object and screwed into the pre-drilled screw hole on the mounting surface. During the screw installation and fixing process, the head 1 of the screw will drive the anti-return ring 7 to rotate on the surface of the fastening washer 2, and the anti-return ring 7 will push the fitting rod 9 into the mounting surface around the through hole of the object through the fixing ring 11, thereby enhancing the stability of the fixed connection between the fastening washer 2 and the mounting surface. In addition, the anti-return groove 6 on the lower surface of the anti-return ring 7 will simultaneously squeeze the surfaces of the auxiliary layer 12 and the fastening washer 2, and the auxiliary layer 12 and the fastening washer... Both are made of rubber. The compressed portion of the auxiliary layer 12 and the fastening pad 2 can be embedded in the check groove 6, thereby increasing the frictional resistance between the fastening pad 2 and the check ring 7, further reducing the probability of the screw loosening. Moreover, the adsorption groove 3 opened on the surface of the fastening pad 2 will form a negative pressure environment after being compressed and deformed, which can further enhance the fixing effect between the fastening pad 2 and the mounting surface. In addition, the worker can inject adhesive into the adhesive groove 8 through the injection hole, using the adhesive to further enhance the stability of the fixed connection between the fastening pad 2 and the mounting surface, thereby enhancing the anti-loosening effect of the screw and ensuring the safety of the object after installation and fixing.

[0020] In a preferred embodiment, the positioning part 4, which is fixedly connected to the lower surface of the head 1, has a cylindrical structure, and the diameter of the positioning part 4 is larger than the diameter of the connecting part 5. At the same time, the head 1, the positioning part 4, and the connecting part 5 adopt an integral molding structure.

[0021] In this embodiment, as Figure 1 and Figure 2 The screw is integrally formed from the head 1, the positioning part 4 and the connecting part 5, which helps to enhance the overall mechanical strength of the screw and reduce the probability of accidental breakage. At the same time, the size of the positioning part 4 facilitates the fixed connection between the screw and the check ring 7.

[0022] In a preferred embodiment, the check ring 7 has a circular ring structure, and the two sets of positioning blocks 13 fixedly connected to the inner side of the check ring 7 are both isosceles trapezoidal structures. The dimensions of the positioning blocks 13 and the positioning grooves 10 opened in the positioning part 4 are matched, and the thickness of the check ring 7 is less than the thickness of the positioning part 4.

[0023] In this embodiment, as Figure 1 and Figure 2 The check ring 7 is made of the same material as the screw, which facilitates the fixed connection between the check ring 7 and the head 1 of the screw. The structure of the positioning block 13 can not only help enhance the stability of the connection between the check ring 7 and the positioning part 4, but also help reduce the probability of breakage at the connection between the positioning block 13 and the check ring 7.

[0024] In a preferred embodiment, multiple sets of check grooves 6 are formed at equal intervals around the lower surface of the check ring 7 in the circumferential direction, and the multiple sets of check grooves 6 are all elongated structures with right-angled triangular structures at the end faces.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The structure of the check groove 6 allows the portion of the surface of the fastening pad 2 located in the check groove 6 to protrude when the check ring 7 presses against the surface of the fastening pad 2. This protrusion can then be embedded in the check groove 6, thereby increasing the frictional resistance when the check ring 7 reverses direction and effectively enhancing the anti-loosening effect of the screw.

[0026] In a preferred embodiment, the fastening pad 2 has a circular ring structure, and an adhesive groove 8 is formed on the outer side of the lower surface of the fastening pad 2. The adhesive groove 8 has a circular ring structure, and four sets of injection holes are symmetrically formed on the top of the adhesive groove 8.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The fastening pad 2 can be made of rubber to enhance its elasticity, which in turn facilitates the anti-reverse effect between the check ring 7 and the fastening pad 2. At the same time, the setting of the adhesive groove 8 and the injection hole allows the worker to inject adhesive between the fastening pad 2 and the mounting surface, which helps to enhance the stability of the fixed connection between the fastening pad 2 and the mounting surface.

[0028] In a preferred embodiment, multiple sets of adsorption grooves 3 are evenly opened on the inner side of the lower surface of the fastening pad 2. The adsorption grooves 3 have a hemispherical structure, and the multiple sets of adsorption grooves 3 are combined together to form a ring distribution.

[0029] In this embodiment, as Figure 1 , Figure 3 and Figure 4The adsorption groove 3 allows the fastening pad 2 to be pressed against the mounting surface, and the adsorption groove 3 can deform to form a negative pressure environment, thereby helping to enhance the fixing effect between the fastening pad 2 and the mounting surface.

[0030] In a preferred embodiment, the fixing ring 11 has a circular structure, and the size of the fixing ring 11 and the buffer groove are matched. The auxiliary layer 12 fixedly connected to the upper surface of the fixing ring 11 has a circular structure, and multiple sets of through holes are opened at equal intervals around the bottom of the inner cavity of the buffer groove. The fitting rod 9 fixedly connected to the lower surface of the fixing ring 11 has a cylindrical structure, and the length of the fitting rod 9 is greater than the thickness of the fastening pad 2.

[0031] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The auxiliary layer 12 can be made of rubber, which can help increase the frictional resistance of the check ring 7 when it reverses on the surface of the auxiliary layer 12. At the same time, the cooperation between the fitting rod 9 and the through hole allows the screw to embed the fitting rod 9 into the mounting surface through the fixing ring 11, which can help enhance the stability of the fixed connection between the fastening pad 2 and the mounting surface, thereby helping to enhance the anti-loosening effect of the screw.

[0032] The anti-loosening screw of this utility model, through the cooperation of the positioning part 4, the check ring 7, the fastening washer 2, the fixing ring 11, and the fitting rod 9, can effectively enhance the stability of the screw after installation and effectively enhance the loosening effect of the screw. At the same time, the fastening washer 2 is fixedly connected to the mounting surface through three methods: the adhesive in the adhesive groove 8, the fitting rod 9 of the fixing ring 11, and the negative pressure adsorption of the adsorption groove 3. This can effectively enhance the fixing effect between the fastening washer 2 and the mounting surface, help reduce the probability of the screw loosening, and the three fixing methods between the fastening washer 2 and the mounting surface can be selected according to the actual situation of the mounting surface.
