[0002] Nuts are a common type of mechanical fastener and are widely used in many fields. Whether it is industrial equipment, building structures or various utensils in daily life, nuts play a vital fastening role. However, in actual use, nuts face many challenges, among which the problem of loosening is particularly prominent.

[0003] In industrial production environments, mechanical equipment is often subjected to high-speed vibration. Due to the intense vibration, high-frequency shocks and impacts are generated, making it easy for nuts connecting various parts of the mechanical equipment to loosen. Once the nuts loosen, the connection between the parts may fail, leading to equipment failure and even serious safety accidents. Existing anti-loosening nut concealment devices usually use multiple nesting or additional locking components to achieve the anti-loosening and concealment functions, which not only significantly increases the manufacturing cost of the device itself; therefore, improvements are needed to address the above problems.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a nut concealment device with anti-loosening function, comprising an annular base 1 installed at the nut, a docking ring platform 2 formed on the top surface of the annular base 1, and a rectangular mounting groove 4 formed on one side of the annular base 1. A rotating rod 11 passes through the rectangular mounting groove 4, and a closing cover 3 is rotatably mounted on the rotating rod 11. This structure allows the annular base 1 to be installed at the nut, the docking ring platform 2 provides a foundation for subsequent component docking, and the rotating rod 11 facilitates the rotation of the closing cover 3, realizing the closing and opening functions, improving the flexibility of the device and the convenience of concealing the nut. The shape of the docking ring platform 2 corresponds to the closing cover 3, and the closing cover 3 is provided with mounting... The mounting ring 5 has two symmetrical T-shaped protrusions 6 on both sides. The corresponding shapes of the mating ring platform 2 and the closing cover 3 facilitate precise mating between the two. The mounting ring 5 and the T-shaped protrusions 6 help to cooperate with other components, enhancing the stability of the device connection and the accuracy of installation. Two dovetail grooves 12 are symmetrically opened on the inner wall of the top surface of the mounting ring 5. A rubber block 7 is inserted into the mounting ring 5. Dovetail blocks corresponding to the dovetail grooves 12 extend from both sides of the rubber block 7. The cooperation between the dovetail grooves 12 and the dovetail blocks allows the rubber block 7 to be firmly installed in the mounting ring 5. The rubber block 7 can increase the friction with the nut, play a role in preventing loosening, and improve the fastening stability of the nut.

[0020] In this invention, T-shaped slots corresponding to T-shaped protrusions 6 are provided on both sides of the top surface of the docking ring platform 2, and a corresponding nut-shaped insertion groove is provided at the center of the rubber block 7. The T-shaped protrusions 6 and T-shaped slots cooperate to further strengthen the connection between the closing cover 3 and the annular base 1. The insertion groove of the rubber block 7 can better wrap the nut, enhance the anti-loosening effect, and improve the overall anti-loosening performance of the device. An insertion protrusion 8 is provided at the top of the closing surface of the closing cover 3, and an insertion interface corresponding to the insertion protrusion 8 is provided on the top surface of the docking ring platform 2. The cooperation between the insertion protrusion 8 and the insertion interface... The closure cover 3 is made to close more tightly, preventing foreign objects from entering and improving the sealing and protection of the device. A waterproof rubber sheet 9 is provided at the connection between the closure cover 3 and the outer wall of the annular base 1. A torsion spring 10 is sleeved on the rotating rod 11. A groove corresponding to one end of the torsion spring 10 is opened on the closure cover 3. One end of the torsion spring 10 abuts against the top surface of the rectangular mounting groove 4. The waterproof rubber sheet 9 can prevent water and other liquids from entering the device and play a waterproof protection role. The torsion spring 10 enables the closure cover 3 to automatically spring open, making it easy to operate the nut and improving the convenience of operation and the efficiency of the device.

[0021] Working principle: When using this utility model, first install the annular base 1 at the nut, and manually press the closing cover 3. As the closing cover 3 gradually moves down, the T-shaped protrusions 6 on both sides of the mounting ring 5 on the closing cover 3 begin to align with the T-shaped slots on the docking ring platform 2 on the top surface of the annular base 1. Continue pressing until the closing cover 3 is completely closed. At this time, the insertion protrusion 8 at the top of the closing surface of the closing cover 3 fits tightly with the insertion interface on the top surface of the docking ring platform 2, completing the locking and fixing. At the same time, the waterproof rubber sheet 9 at the connection between the closing cover 3 and the outer wall of the annular base 1 prevents dust, debris and moisture from entering. The dovetail blocks on both sides of the rubber block 7 cooperate with the dovetail groove 12 on the inner wall of the top surface of the mounting ring 5, and are firmly installed in the mounting ring 5. The insertion groove at its axis, corresponding to the shape of the nut, tightly wraps around the nut, increasing friction and preventing the nut from loosening. The device is now in use.
