[0002] Bolt is a tool that uses the physical and mathematical principles of the inclined surface of an object and friction to tighten machine parts gradually. Bolt is a general term for fasteners, and is a common term in daily life. Bolts are essential industrial necessities in daily life: very small bolts are used in cameras, glasses, watches, electronics, etc.; general bolts are used in televisions, electrical appliances, musical instruments, furniture, etc.; large bolts, nuts are used in engineering, construction, bridges; and both large and small bolts are used in transportation devices, airplanes, electric trains, cars, etc. Bolts play an important role in industry, and as long as there is industry on earth, the function of bolts will always be important. Bolts are a common invention in the production and life of people over the past thousand years. In today's social context, bolts have more or less applications in various aspects of industry and life, and they are assembled in various parts and products, but there are risks of bolt loosening and breaking, and once the bolt loosens, safety problems are likely to occur. There are various anti-loose structures on the market today, such as double-nut type, self-locking nut type, and stop washer type, but their clamping forces are relatively small. Therefore, there is an urgent need for an anti-loose bolt assembly to solve the above technical problems. SUMMARY

[0003] The purpose of the present application is to provide an anti-loose bolt assembly to solve the problem of small clamping force of the anti-loose structure, easy loosening, and potential safety hazards.

[0004] To achieve the above purpose, the present application provides an anti-loose bolt assembly, which comprises an anti-loose bolt, a mounting nut, an anti-slip washer, an adaptive screw rod, an anti-loose sheet and an assembled part. The assembled part, the anti-loose sheet and the anti-slip washer pass through the anti-loose bolt in sequence. The end of the anti-loose bolt close to the anti-slip washer is connected with the adaptive screw rod, and the end of the adaptive screw rod away from the anti-slip washer is connected with the mounting nut. The anti-loose bolt is provided with double-sided openings.

[0005] Preferably, the top end of the adaptive screw rod is provided with a protruding cylinder, a spring is sleeved on the protruding cylinder, and a spring positioning sheet is arranged at the end of the spring away from the protruding cylinder.

[0006] Preferably, the end of the spring positioning sheet close to the spring is provided with a limiting groove two adapted to the spring.

[0007] Preferably, an anti-slip groove is formed in the anti-slip washer.

[0008] Preferably, a limiting groove is provided on one side of the anti-loosening plate, and the diameter of the limiting groove is the same as the diameter of the spring positioning plate.

[0009] Preferably, the top of the adapter screw and the top of the anti-loosening bolt are both made of magnetic material.

[0010] Preferably, the anti-loosening bolt and the adapter screw are respectively provided with concave thread and convex thread, and the concave thread and the convex thread are compatible.

[0011] Therefore, the present invention employs the above-mentioned anti-loosening bolt assembly, which has the following beneficial effects:

[0012] (1) In this invention, the spring is compressed to generate spring force, which causes the spring positioning plate to give the anti-loosening plate an axial force. Due to the existence of this axial force, the assembled parts between the anti-loosening plate and the anti-loosening bolt can be locked, thereby playing an anti-loosening role. It has a wide range of applications, ingenious design, good performance, and high safety factor.

[0013] (2) Even if the mounting nut becomes loose, it can still maintain normal operation for a short time without safety issues due to the spring force.

[0014] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0028] The following detailed description of embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application as claimed, but merely represents selected embodiments of the application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0029] Please refer to Figures 1-10The application discloses a loosening-preventing bolt assembly, which comprises a loosening-preventing bolt 7, a mounting nut 1, an anti-skid washer 5, an adapting screw 2, a loosening-preventing washer 6 and an assembled part 14. The anti-skid washer 5, the loosening-preventing washer 6 and the assembled part 14 are sequentially penetrated by the loosening-preventing bolt 7. The loosening-preventing bolt 7 is connected with the adapting screw 2 at an end close to the anti-skid washer 5. The adapting screw 2 is connected with the mounting nut 1 at an end away from the anti-skid washer 5. The connecting position of the loosening-preventing bolt 7 and the adapting screw 2 is respectively provided with a female thread 10 and a male thread 11, and the female thread 10 and the male thread 11 are matched. The loosening-preventing bolt 7 is provided with a double-side opening 9. The top end of the adapting screw 2 is provided with a protruding cylinder 13. The protruding cylinder 13 is sleeved with a spring 3. The end of the spring 3 away from the protruding cylinder 13 is provided with a spring positioning piece 4. The end of the spring positioning piece 4 close to the spring 3 is provided with a limiting groove 16 matched with the spring 3. The anti-skid washer 5 is provided with an anti-skid groove 17. One side of the loosening-preventing washer 6 is provided with a limiting groove 15, and the size of the limiting groove 15 is the same as that of the spring positioning piece 4. The top of the adapting screw 2 and the top of the loosening-preventing bolt 7 are made of magnetic material. In the specific installation, the loosening-preventing bolt 7 is first assembled in the assembled part 14, then the loosening-preventing washer 6 is assembled on the assembled part 14 through the double-side opening 9 of the loosening-preventing bolt 7, the limiting groove 15 of the loosening-preventing washer 6 is outwardly directed, the spring 3 is sleeved on the top protruding cylinder 13 of the adapting screw 2, the other side of the spring 3 is connected to the limiting groove 16 of the spring positioning piece 4, the assembly is spirally connected through the female thread 10 of the loosening-preventing bolt 7 and the male thread 11 of the adapting screw 2, the top end 8 of the loosening-preventing bolt and the top end 12 of the adapting screw are butted, the spring positioning piece 4 is butted in the limiting groove 15 of the loosening-preventing washer 6, and the spring 3 is in a compressed state. The anti-skid washer 5 is sleeved on the loosening-preventing bolt 7 and connected with the loosening-preventing washer 6, the side of the anti-skid washer 5 with the anti-skid groove 17 is outwardly directed, finally, the mounting nut 1 and the adapting screw are spirally connected, the mounting nut 1 is connected with the side of the anti-skid washer 5 with the anti-skid groove 17 after being rotated to the position, and is located at the connecting position of the loosening-preventing bolt 7 and the adapting screw 2.

[0030] Working principle: when the adapting screw 2 and the lock bolt 7 are connected by screwing, the spring 3 on the convex cylinder 13 at the top of the adapting screw 2 is in a compressed state after being connected, and a large spring force is generated, which is transmitted to the lock plate 6 through the spring positioning sheet 4, so that a large extrusion force is generated between the lock plate 6 and the lock bolt 7, and the assembled part is in a locked state. Since the mounting nut 1 is located at the connection between the adapting screw 2 and the lock bolt 7, it is difficult for the connection between the adapting screw 2 and the lock bolt 7 to loosen, and the top end 12 of the adapting screw and the top end 8 of the lock bolt are both made of magnetic material, so that the magnetic force generated further makes it difficult for the connection between the adapting screw 2 and the lock bolt 7 to loosen. Since the top end of the adapting screw 2 has the convex cylinder 13 and the limiting groove two 16 on the spring positioning sheet 4, the spring 3 can be prevented from shaking and swinging, so that the spring force is parallel to the axial direction, and the limiting groove one 15 on the lock plate 6 can maximize the spring force acting on the lock plate 6, wherein the spring 3 adopts a spring with a large elastic coefficient, which can generate a large spring force, so that the lock effect is more obvious. The anti-slip washer 5 can effectively prevent the mounting nut 1 from loosening due to the existence of the anti-slip groove 17. Finally, even if the mounting nut 1 loosens, the assembly can still operate normally for a short time without safety problems due to the spring force.

[0031] Therefore, the anti-loose bolt assembly is adopted to solve the problem of small clamping force, easy loosening and safety hidden trouble of the existing anti-loose structure. The spring force generated by the compression of the spring makes the spring positioning sheet generate an axial force on the lock plate, and the assembled part between the lock plate and the lock bolt is locked due to the existence of the axial force, so that the anti-loose effect is achieved, and the application is wide, the design is ingenious, and the use effect is improved.

[0032] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
