Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Please refer to Figure 1-Figure 6The present invention provides a technical solution: a fastener sleeve locking device, comprising: a fastener sleeve 1, a locking washer 2 and a locking nut 3. The fastener sleeve 1 is the core component of the entire device, and is mainly used to install and fix the shaft or other rotating parts. Its design usually has a precise inner diameter to ensure a tight fit with the fixed parts. The locking washer 2 is located on the outer wall of the fastener sleeve 1, and its main function is to increase the friction between the locking nut 3 and the fastener sleeve 1 to prevent the locking nut from loosening under vibration or impact. The locking washer 2 is made of elastic material and has a certain deformation ability, and can provide a better locking effect during the locking process. The locking nut 3 is a key component of the fastener sleeve 1 locking device, and is used to firmly fix the fastener sleeve 1 on the shaft. It presses the locking washer 2 by rotating, thereby achieving the locking of the fastener sleeve 1.

[0022] A locking gasket 2 is provided on the outer wall of one end of the fixing sleeve 1, a locking nut 3 is provided on the outer side of the locking gasket 2, a lower gasket 4 is provided on the outer side of the locking nut 3, and the lower gasket 4 is located between the locking nut 3 and the rubber support sleeve 5, and mainly plays an isolation and protection role. It can prevent the locking nut 3 from directly pressing the rubber support sleeve 5, causing excessive deformation or damage to the rubber material. At the same time, the lower gasket 4 can also provide a certain rigid support to enhance the stability of the entire device. A rubber support sleeve 5 is provided on the outer side of the lower gasket 4. The rubber support sleeve 5 is an important elastic element in the locking device of the fixing sleeve 1, which is used to absorb vibration and impact energy. It is located between the lower gasket 4 and the socket 6. Through its elastic deformation ability, it can apply a reverse force to the outer nut 8 and the locking nut 3 when the fixing sleeve is vibrated or impacted, thereby preventing them from loosening. The rubber support sleeve 5 can also provide a certain sound insulation and shock absorption effect.

[0023] A dimple 6 is provided on the outside of the rubber support sleeve 5. The dimple 6 is located on the outside of the rubber support sleeve 5 and mainly plays a role of strengthening and supporting. It can increase the stability of the rubber support sleeve 5 and prevent it from being excessively deformed when subjected to force. At the same time, the design of the dimple 6 can also be closely matched with the rubber support sleeve 5 to ensure the effective absorption of vibration and impact energy. An upper gasket 7 is provided on the outside of the dimple 6. The upper gasket 7 is located between the dimple 6 and the outer nut 8, and also plays an isolation and protection role. It can prevent the outer nut 8 from directly pressing the dimple 6, causing the dimple 6 to be deformed or damaged. The upper gasket 7 can also provide a certain rigid support to enhance the stability of the entire device. An outer nut 8 is provided on the outside of the upper gasket 7. The top surface of the rubber support sleeve 5 abuts against the inner wall of the dimple 6, and the bottom surface of the rubber support sleeve 5 abuts against the lower gasket 4. The outer nut 8 is the outermost component of the locking device of the fixing sleeve 1, and is used to firmly fix the entire device on the external structure. It presses the upper gasket 7 and the dimple 6 and other components by rotating to ensure the stability of the entire device. The outer nut 8 is usually designed to have a larger size and strength to withstand greater tension and pressure.

[0024] When the adapter sleeve locking device is in use, the locking of the adapter sleeve 1 is achieved by means of the locking gasket 2 and the locking nut 3. An elastic rubber supporting sleeve 5 and a socket 6 are arranged on the outside of the locking nut 3. In addition, the outer end is locked by the outer nut 8. When the adapter sleeve 1 is subjected to vibration or impact during use, force is applied to the outer nut 8 and the locking nut 3 through the elastic force of the socket 6 and the rubber supporting sleeve 5, so as to prevent the locking nut 3 and the external thread 8 from loosening and ensure the stability of the adapter sleeve 1.

[0025] An external thread is provided on the outer wall of one end of the adapter sleeve 1, and an internal thread matching the external thread is provided on the inner wall of the locking nut 3 and the outer nut 8. The external thread is provided on the outer wall of one end of the adapter sleeve 1, and this design enables the adapter sleeve to achieve reliable threaded connection with other components with internal threads. The existence of the external thread provides the basis for mechanical locking, ensuring that the adapter sleeve 1 can be firmly fixed on the shaft or connected with other components. In addition, the external thread also facilitates the rotation operation during installation and disassembly, improving work efficiency. The internal thread of the inner wall of the locking nut 3 is designed to match the external thread of the adapter sleeve to form a tight threaded connection. This design not only increases the reliability of locking, but also effectively prevents the adapter sleeve from loosening under vibration or impact. By rotating the locking nut 3, the adapter sleeve can be pressed and locked to ensure the stability and safety of the entire device. The internal thread of the inner wall of the outer nut 8 is designed to match the external thread of the adapter sleeve 1 to form an additional threaded connection layer. This design increases the strength and stability of the entire locking device, especially when it needs to withstand large external forces or vibrations. The existence of the outer nut 8 also provides additional locking force to prevent the locking nut 3 from loosening due to vibration or impact. In addition, the internal thread design of the outer nut 8 is also convenient for connecting with other parts with external threads, increasing the flexibility and applicability of the device.

[0026] The nest 6 is in an inverted disc shape, and a through hole is provided in the middle of the nest 6. The nest 6 is made of elastic steel. An outer flange is provided at the bottom of the nest 6, and the outer flange of the nest 6 abuts against the lower gasket 4. The nest 6 is designed to be in an inverted disc shape, and this shape enables it to be firmly supported in the tight sleeve locking device, while providing enough area to disperse and withstand pressure and vibration from the outside. The inverted design also helps to ensure the close contact between the nest 6 and the rubber support sleeve 5, the lower gasket 4 and other components, thereby improving the stability and reliability of the entire device. The through hole design in the middle of the nest 6 allows the tight sleeve or other shaft components to pass through, thereby realizing the installation and fixation of the device. The presence of the through hole not only simplifies the installation process, but also ensures that the shaft components can rotate smoothly without being hindered by the nest. The nest 6 is made of elastic steel, which has good elasticity and recovery, and can be deformed and quickly restored to its original shape when subjected to external force. This characteristic enables the nest 6 to effectively absorb and disperse vibration and impact energy, and protect the tight sleeve locking device from damage. At the same time, the elastic steel material also has good strength and durability, ensuring the stability and reliability of the nest 6 in long-term use. The outer flange design at the bottom of the nest 6 increases the contact area between the nest and the lower gasket 4, thereby improving the connection strength and stability between them. The outer flange of the nest 6 abuts against the lower gasket 4, and this design ensures close contact and firm connection between them. This connection method not only improves the stability and reliability of the entire device, but also can effectively prevent vibration and impact from damaging the internal components of the device. At the same time, the abutment of the outer flange and the lower gasket 4 also plays a positioning role, ensuring the correct position of the nest 6 during installation.

[0033] In this embodiment: the outer circumference of the locking gasket 2 is provided with a notch, and there are several notches, and the several notches are evenly arranged in the circumferential direction on the locking gasket 2.

A screw 11 is provided in the middle of the clamping gasket 10, and a threaded sleeve 9 is provided inside the locking nut 3 and outside the screw 11. The design of the threaded sleeve 9 provides a stable support and fixing point for the screw 11. Through the threaded connection between the threaded sleeve 9 and the inside of the locking nut 3, the screw 11 is firmly fixed on the locking nut 3. The design of the screw 11 enables the clamping gasket 10 to be further fixed on the locking nut 3.

There are multiple swivel seats 12, and multiple swivel seats 12 are evenly arranged in the circumferential direction at the bottom of the locking gasket 2. The design of the swivel seat 12 provides a mounting base for the swivel rod 13. The design of the swivel rod 13 is the key to achieving the relative rotation restriction between the locking gasket 2 and the fastening sleeve 1. Through the clamping connection between the swivel rod 13 and the clamping seat 14, it can be ensured that the locking gasket 2 will not rotate relative to the fastening sleeve 1 when subjected to external force. This design not only improves the locking performance of the locking device, but also prevents loosening or damage caused by relative rotation. The design of the clamping seat 14 provides a clamping point for the swivel rod 13. By arranging the holder 14 on the outer wall of the adapter sleeve 1, it can be ensured that the rotating rod 13 can correctly cooperate with the holder 14, thereby realizing the relative rotation restriction between the locking washer 2 and the adapter sleeve 1. The uniform circumferential arrangement of multiple rotating seats 12 can ensure that the locking washer 2 can be uniformly stressed when subjected to external forces, thereby improving the stability and reliability of the entire device. At the same time, the design of multiple rotating seats 12 can also increase the number of connection points between the locking washer 2 and the adapter sleeve 1, further improving the locking performance of the locking device.

[0036] When the adapter sleeve locking device is in use, the adapter sleeve 1 is locked by the locking washer 2 and the locking nut 3. An elastic rubber support sleeve 5 and a dimple 6 are arranged on the outside of the locking nut 3. In addition, the outer end is locked by the outer nut 8. When the adapter sleeve 1 is subjected to vibration or impact during use, the elastic force of the dimple 6 and the rubber support sleeve 5 is used to apply force to the outer nut 8 and the locking nut 3, so that the locking nut 3 and the external thread 8 can be prevented from loosening, thereby ensuring the stability of the adapter sleeve 1. In addition, during the use of the adapter sleeve, by fixing the locking nut 3 and the locking washer 2 together through the screws 11, the clamping washer 10 and the threaded sleeve 9, and coordinating the clamping fixation of the rotating rod 13 and the clamping seat 14, the locking washer 2 can be prevented from rotating relative to the adapter sleeve 1, thereby preventing the locking nut 3 from rotating relative to the adapter sleeve 1, thereby ensuring the locking performance of the locking device.
