Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, and relates to a nut, and more particularly to a nut that can automatically lock. Background Technology

[0002] Nuts are fasteners that are screwed onto bolts or screws to provide a fastening effect. Depending on the material, they are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] Traditional nuts do not have a self-locking function during use. During equipment operation, due to external forces such as vibration and impact, nuts can easily become loose. In a car engine, the engine generates strong vibrations when it is running. If the nut becomes loose, it may cause the parts to be not firmly connected, leading to engine failure and even affecting driving safety. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a nut that is self-locking after connection, has high stability, and can automatically lock.

[0005] The purpose of this utility model can be achieved through the following technical solution: an automatically locking nut, including a nut body, a washer fixedly connected to the bottom of the nut body, a threaded hole opened on the surface of the nut body, a connecting block provided on the surface of the nut body, a spring fixedly connected between the nut body and the connecting block, a locking piece fixedly connected to the surface of the connecting block, and an inclined block fixedly connected to the top of the connecting block.

[0006] By incorporating a nut body, threaded hole, connecting block, spring, and locking plate, the locking plate automatically locks the nut after it is tightened, as it comes into close contact with the stud under the spring tension. This eliminates the need for additional anti-loosening devices, greatly simplifying the installation process and improving work efficiency. When the tool sleeve is fitted with the nut, the sleeve pushes the wedge block to move, which in turn moves the connecting block and locking plate, keeping the locking plate away from the inner cavity of the threaded hole, thus facilitating the installation and removal of the nut.

[0007] In the aforementioned self-locking nut, the locking plate extends through the nut body and into the inner cavity of the threaded hole on the side away from the connecting block, and the locking plate is movably connected to the nut body. The locking plate can contact the stud more directly, increasing the contact area and friction, enhancing the locking effect on the nut, effectively preventing the nut from loosening due to vibration, and improving the reliability of the connection.

[0008] In the aforementioned self-locking nut, a first groove is formed on the surface of the nut body, and a second groove is formed on the surface of the connecting block. One side of the spring extends into the inner cavity of the first groove and is fixedly connected to the inner wall of the first groove, while the other side of the spring extends into the inner cavity of the second groove and is fixedly connected to the inner wall of the second groove. By providing the first and second grooves, a stable installation space is provided for the spring, sealing it internally and preventing it from contacting the external environment, thus ensuring the reliability of the automatic locking function.

[0009] In the aforementioned self-locking nut, the top of the washer is provided with a groove, and the bottom of the connecting block is fixedly connected to a slider. The bottom of the slider extends into the inner cavity of the groove and is movably connected to the groove. By setting the groove and slider, precise guidance is provided for the movement of the connecting block, allowing the connecting block to move stably along the groove under the action of the spring. This ensures that the locking plate can accurately contact and separate from the stud, improving the accuracy and reliability of the automatic locking.

[0010] In the aforementioned self-locking nut, an anti-slip pad is adhered to the bottom of the washer, and the bottom of the anti-slip pad has anti-slip patterns. When the nut is installed on the equipment, the anti-slip pad contacts the mounting surface, and the anti-slip patterns increase the friction between the pad and the mounting surface, further preventing the nut from rotating or loosening due to external forces during use. This better resists the influence of external forces and ensures a stable connection of the equipment.

[0011] In the aforementioned self-locking nut, the top of the nut body is hexagonal, and the bottom of the washer is annular. The hexagonal nut facilitates connection with socket tools, allowing for easy installation and removal using standard tools without the need for specially customized tools, thus improving operational convenience and versatility.

[0012] Compared with existing technologies, the advantages of this self-locking nut are: after the nut body is tightened, the locking plate can make close contact with the stud under the action of the spring thrust, realizing the automatic locking of the nut. No additional anti-loosening device is required, which greatly simplifies the installation process, improves work efficiency, and enhances safety. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the automatically locking nut includes a nut body 1, a washer 2 fixedly connected to the bottom of the nut body 1, a threaded hole 3 opened on the surface of the nut body 1, a connecting block 4 provided on the surface of the nut body 1, a spring 5 fixedly connected between the nut body 1 and the connecting block 4, a locking piece 6 fixedly connected to the surface of the connecting block 4, and an inclined block 7 fixedly connected to the top of the connecting block 4.

[0019] To elaborate further, the locking piece 6, on the side away from the connecting block 4, penetrates the nut body 1 and extends into the inner cavity of the threaded hole 3, with the locking piece 6 movably connected to the nut body 1. A first groove 8 is formed on the surface of the nut body 1, and a second groove 9 is formed on the surface of the connecting block 4. One side of the spring 5 extends into the inner cavity of the first groove 8 and is fixedly connected to the inner wall of the first groove 8, while the other side of the spring 5 extends into the inner cavity of the second groove 9 and is fixedly connected to the inner wall of the second groove 9.

[0020] In actual manufacturing, the top of the washer ring 2 has a groove 10, and the bottom of the connecting block 4 is fixedly connected to a slider 11. The bottom of the slider 11 extends into the inner cavity of the groove 10 and is movably connected to the groove 10. An anti-slip pad 12 is adhered to the bottom of the washer ring 2, and the bottom of the anti-slip pad 12 is provided with anti-slip texture. The top of the nut body 1 is hexagonal, and the bottom of the washer ring 2 is annular.

[0021] In use, the sleeve is fitted onto the surface of the nut body 1. The sleeve pushes the inclined block 7 to move, and the inclined block 7 drives the connecting block 4 and the locking plate 6 to move, so that the locking plate 6 moves away from the inner cavity of the threaded hole 3, and the nut body 1 is rotated and installed on the surface of the stud. After installation, the sleeve is removed, and the spring 5 pulls the connecting block 4 and the locking plate 6, so that the locking plate 6 presses against the stud to lock and fix the nut.
