[0018] This specific embodiment is an integrated anti-loosening nut, and its structural schematic diagram is as follows. Figure 1-7 As shown, the anti-loosening nut includes a nut body 1. An assembly hole 101 is provided inside the nut body 1. A set of strip-shaped limiting grooves 102 are provided on all four sides of the inner wall of the assembly hole 101. Four sets of positioning grooves 103 are provided at the bottom of the nut body 1 outside the assembly hole 101. A fixing hole 1031 is provided at the top of the inner wall of the positioning groove 103.
[0019] The nut body 1 has a rubber fastening sleeve 2 embedded inside. The rubber fastening sleeve 2 consists of a sealing ring 201, a fastener 202, and an anti-slip ring 203. The top of the fastener 202 is fixedly connected to the sealing ring 201 at the top of the nut body 1. The top of the sealing ring 201 has anti-slip grooves 2011, which enhance the anti-slip performance of the nut body 1 after tightening the bolt. A limiting strip 2021 is fixedly connected to the outer side of the fastener 202 at a position corresponding to the strip-shaped limiting groove 102. The fastener 202 is connected to the strip-shaped limiting groove 102 through the limiting strip 2021, which initially limits the rubber fastening sleeve 2 inside the nut body 1. The fastener 202 has an internal threaded hole 2022 inside. The bottom of the fastener 202 is fixedly connected to the bottom of the nut body 1 with an anti-slip ring 203. The anti-slip ring 203 has a metal shaping ring 2031 inside. 031 The anti-slip ring 203 is shaped so that it is flatly set at the bottom of the nut body 1, improving the anti-slip performance of the nut body 1 when fixed to the mechanical equipment. A positioning post 2032 is fixedly connected to the top of the anti-slip ring 203 at the position corresponding to the positioning groove 103. The anti-slip ring 203 is inserted into the positioning groove 103 through the positioning post 2032, further limiting the rubber fastening sleeve 2 inside the nut body 1. The metal shaping ring 2031 and the positioning post 2032 are both provided with mounting holes 2033 at the positions corresponding to the fixing hole 1031. The screw passes through the mounting hole 2033 and the fixing hole 1031 to fix the anti-slip ring 203 at the bottom of the rubber fastening sleeve 2 to the bottom of the nut body 1, improving the stability of the rubber fastening sleeve 2 installed inside the nut body 1 and preventing the fastener 202 from slipping when the nut body 1 is threadedly connected to the bolt through the internal thread hole 2022.
[0020] Furthermore, a set of positioning components 3 are fixedly connected to both sides of the nut body 1. A reinforcing rib 301 is fixedly connected to the connection between the positioning component 3 and the nut body 1. The reinforcing rib 301 enhances the connection strength between the positioning component 3 and the nut body 1. A second mounting hole 302 is opened through the end of the positioning component 3 away from the nut body 1. After the nut body 1 is tightened with the bolt, the positioning component 3 is fixed to the mechanical equipment by the screw through the second mounting hole 302, which limits and fixes the nut body 1, further improving the stability of the nut body 1 installed on the bolt. An anti-slip pad 303 is fixedly connected to the bottom of the end of the positioning component 3 away from the nut body 1. The anti-slip pad 303 enhances the anti-slip properties of the positioning component 3 when in contact with the mechanical equipment.
[0021] When using the anti-loosening nut of this technical solution, firstly, pinch the sealing ring 201 and fastener 202 of the rubber fastening sleeve 2, allowing it to deform due to the flexibility of the rubber and easily squeeze into the assembly hole 101 of the nut body 1, so that the nut body 1 is fitted onto the outside of the rubber fastening sleeve 2. The fastener 202 is connected to the strip-shaped limiting groove 102 through the limiting insert 2021, which initially limits the rubber fastening sleeve 2 inside the nut body 1. The anti-slip ring 203 is connected to the positioning groove 103 through the positioning post 2032, which further limits the rubber fastening sleeve 2 inside the nut body 1. The screw passes through the mounting hole 2033 and the fixing hole 1031 to fix the anti-slip ring 203 at the bottom of the rubber fastening sleeve 2 to the bottom of the nut body 1, improving the installation of the rubber fastening sleeve 2 inside the nut body 1. To ensure stability and prevent slippage of the fastener 202 when the nut body 1 is threaded to the bolt through the internal threaded hole 2022, the metal shaping ring 2031 shapes the anti-slip ring 203, ensuring that the anti-slip ring 203 is flatly positioned at the bottom of the nut body 1, thus improving the anti-slip performance of the nut body 1 when fixed to the mechanical equipment. The nut body 1 is threaded to the bolt through the internal threaded hole 2022 of the fastener 202, securing the mechanical components with bolts. The rubber fastening sleeve 2, made of rubber material, has good sealing and anti-slip properties, effectively improving the tightness of the nut body 1 and the bolt. The positioning component 3 is fixed to the mechanical equipment with screws through the mounting hole 302, thereby limiting and fixing the nut body 1, further improving the stability of the nut body 1 installed on the bolt, and preventing the nut body 1 from loosening and falling off.
[0022] The entire operation process is simple and convenient. Compared with existing anti-loosening nuts, this utility model can improve the tightness of the assembly and fixation of the nut and bolt through design, avoid the nut from loosening and falling off when the mechanical equipment moves and vibrates, and enhance the overall practicality.
[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
