Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] As Figures 1-7As shown in the figure, a quick-release rotating shaft provided by the utility model includes a fixing plate 1, a shaft rod 2 and a rotating member 3. The shaft rod 2 is movably connected to the rotating member 3. The fixing plate 1 is provided with a plug hole 4 and a fixing hole 5. The plug hole 4 is fixedly connected to the shaft rod 2 through a plug member 6. The shaft rod 2 includes an assembly section 7 and a fixing section 8. The shaft rod 2 is movably connected to the rotating member 3 through the assembly section 7. The plug hole 4 is a flat hole, and the plug hole 4 is coupled with the plug member 6. A gasket group 9 and a nut 10 are fixedly installed on the assembly section 7. The gasket group 9 sequentially includes a first ordinary gasket 11, a first elastic gasket 12, a second elastic gasket 13 and a second ordinary gasket 14. The rotating member 3 is provided with a connecting arm 15, and the connecting arm 15 is provided with a U-shaped assembly port 16. The number of the connecting arms 15 is 3. The materials of the fixing plate 1, the shaft rod 2 and the rotating member 3 are all stainless steel.

[0023] Through the above technical solution, the fixing plate 1 of the present invention is provided with a plug hole 4, the shaft rod 2 is provided with a plug member 6, and the plug member 6 is inserted into the plug hole 4 to fix the shaft rod 2 on the fixing plate 1. The rotating member 3 is movably installed on the shaft rod 2. When installing the present invention, the fixing plate 1 is separated from the shaft rod 2. The fixing plate 1 is fixed on the first structural object, and the rotating member 3 is installed on the second structural object. When in use, the plug member 6 of the shaft rod 2 is inserted into the plug hole 4 of the fixing plate 1, so that the first structural object and the second structural object are connected by a rotating shaft. When the first structural object and the second structural object need to be disassembled and separated, the plug member 6 of the shaft rod 2 is pulled out of the plug hole 4 of the fixing plate 1, and the disassembly is quickly completed.

[0024] Embodiment 2:

[0025] As Figures 1-7As shown in the figure, the utility model includes a fixing plate 1, a shaft rod 2 and a rotating member 3. The surface of the fixing plate 1 is provided with a socket hole 4 and a fixing hole 5. The socket hole 4 is used to connect with the shaft rod 2, and the fixing hole 5 is used for further fixing measures, that is, using screws to pass through the fixing hole 5 to fix the fixing plate 1 at the rotating shaft installation position. The shaft rod 2 has two main parts, namely an assembly section 7 and a fixing section 8. The assembly section 7 is movably connected to the rotating member 3, and the fixing section 8 is connected to the fixing plate 1 through a socket member 6. The socket member 6 is an extended convex structure of the fixing section 8. Through this design, the assembly section 7 of the shaft rod 2 can rotate relative to the rotating member 3, and the shaft rod 2 is fixed on the fixing plate 1 by means of socket connection, that is, the socket member 6 is inserted and fixed with the socket hole 4, so that the shaft rod 2 is fixed on the fixing plate 1. When disassembling, by pulling out the socket member 6 in the socket hole 4, the shaft rod 2 is separated from the fixing plate 1 to complete rapid disassembly. The socket hole 4 enables the shaft rod 2 to be connected to the fixing plate 1 in a simple manner. The socket member 6 firmly connects the shaft rod 2 and the fixing plate 1 through the socket hole 4. Such a connection method not only ensures the stability of the shaft rod 2 during use, but also simplifies the installation process of the rotating shaft. When the rotating shaft needs to be disassembled, only by taking out the socket member 6 from the socket hole 4, the shaft rod 2 and the fixing plate 1 can be conveniently separated without using traditional bolt tools, which greatly improves the disassembly efficiency. The assembly section 7 of the shaft rod 2 is combined with the rotating member 3 through a movable connection. This design enables the rotating member 3 to rotate freely relative to the shaft rod 2 when the rotating shaft is working. The fixing section 8 is combined with the fixing plate 1 through the socket member 6, ensuring the stable support of the shaft rod 2 on the fixing plate 1, so that the shaft rod 2 can maintain a stable position during the operation of the rotating shaft. The installation process of the present invention is simpler and more efficient. The fixing plate 1 and the rotating member 3 are pre-assembled separately, that is, fixed on two objects that need to rotate relative to each other. The rotating member 3 and the shaft rod 2 are an integral assembly structure, that is, they are already assembled at the factory. When the rotating shaft needs to be rotated, the fixing section 8 of the shaft rod 2 is connected to the socket hole 4 on the fixing plate 1 through the socket member 6 to quickly complete the installation of the rotating shaft structure. In this process, the installer only needs to perform a simple socket connection operation to complete the installation of the rotating shaft without the need for cumbersome bolt fixing. When the structural objects connected by the rotating shaft need to be disassembled and separated, by pulling out the socket member 6 in the socket hole 4, the shaft rod 2 is separated from the fixing plate 1 to complete rapid disassembly. During use, the disassembly of the quick-release rotating shaft is also very simple. Just operate in reverse, and the socket member 6 can be taken out from the socket hole 4, and the connection between the shaft rod 2 and the fixing plate 1 will be released accordingly.

[0026] The shape of the insertion hole 4 of the present utility model is a flat hole. The coupling connection method between the flat hole and the insert 6 further enhances the firmness of the connection. In this connection method, the contact between the flat hole and the insert 6 is very tight, so that the rotating shaft can bear a large working load without loosening after installation. During the use of the rotating shaft, the design of the flat hole also plays a role in preventing the shaft rod 2 from rotating. Due to the specific shape of the flat hole, it can provide good directional support for the insert 6 after insertion, thus preventing the offset of the shaft rod 2 during rotation. The coupling connection between the flat hole and the insert 6 also makes the disassembly process of the rotating shaft simpler. The coupling connection design allows the insert 6 to be pulled out of the flat hole when needed. During disassembly, the operator only needs to apply an appropriate force to the insert 6 to take it out of the flat hole without additional tools or complex operation steps. This disassembly method not only saves time but also reduces labor intensity, making the maintenance work more efficient and convenient. In addition, the design of the flat hole can also position the insert 6 more accurately. In the flat hole, the insert 6 can be accurately fixed in the predetermined position, thus preventing functional problems caused by inaccurate positions. The accurate positioning also ensures the geometric stability of the rotating shaft during operation, which helps to improve the overall performance and working reliability of the equipment.

[0027] A gasket set 9 and a nut 10 are fixedly mounted on the assembly section 7 of the utility model, thereby improving the working performance and durability of the rotating shaft. The gasket set 9 includes four main parts, namely, a first common gasket 11, a first elastic gasket 12, a second elastic gasket 13 and a second common gasket 14. The first common gasket 11 and the second common gasket 14 are respectively located at the two ends of the gasket set 9. The common gaskets (11, 14) are used to clamp the elastic gaskets (12, 13). Since the surface of the elastic gaskets (12, 13) is not a flat plane, it is easy to wear the rotating part 3. The elastic gaskets (12, 13) are clamped by the common gaskets (11, 14), thereby reducing friction and wear caused by direct contact, thereby improving the service life of the rotating part 3. Two elastic gaskets (12, 13) are arranged between the common gaskets (11, 14), namely, the first elastic gasket 12 and the second elastic gasket 13. The main function of the elastic gaskets (12, 13) is to provide elastic buffering in the axial direction. This buffering performance is essential for the smooth operation of the shaft. The elastic gaskets (12, 13) can absorb and alleviate the vibration and impact caused by rotation and external forces during the operation of the shaft. This buffering effect can reduce the direct impact between the rotating member 3 and the assembly section 7, reduce wear and noise, and improve the operation stability of the shaft. The arrangement of the first elastic gasket 12 and the second elastic gasket 13 can ensure that uniform elastic support is provided under different operating conditions of the shaft. These elastic gaskets (12, 13) will deform to a certain extent when subjected to force, thereby dispersing the axial force applied to the shaft and preventing excessive force from being concentrated in a single part. This dispersion effect not only prolongs the service life of the shaft and its related components, but also enhances the adaptability of the shaft when bearing operating loads. The nut 10 in the gasket group 9 is responsible for fixing the entire gasket group 9 on the assembly section 7 to ensure that all gaskets can be correctly positioned and function. The tightening effect of the nut 10 enables the gasket group 9 to be firmly clamped between the assembly section 7 and the rotating member 3 to maintain the relative stability of the assembly during operation.

[0028] The rotating member 3 of the utility model is equipped with a connecting arm 15, and the connecting arm 15 is provided with a U-shaped assembly opening 16. The function of the U-shaped assembly opening 16 is to firmly fix the rotating member 3 to the structural object on which the rotating shaft needs to be installed. The provision of the connecting arm 15 enables the rotating member 3 to be better combined with the overall structure of the rotating shaft. The design of the U-shaped assembly opening 16 provides a fixed position for the rotating member 3, so that the rotating member 3 can be safely and stably installed on the structural object. In actual operation, after the rotating member 3 is docked to the structural object through the U-shaped assembly opening 16, a firm connection is formed between the rotating member 3 and the structural object, ensuring that the normal operation of the rotating shaft will not be affected by the loosening of the rotating member 3 during use.

[0029] The rotating part 3 of the present utility model is provided with three connecting arms 15. Each connecting arm 15 is provided with a U-shaped assembly port 16 for firmly fixing the rotating part 3 to a structural object. The three connecting arms 15 enable the rotating part 3 to obtain balanced support on the structural object. Each connecting arm 15 is docked with the corresponding part of the structural object through the U-shaped assembly port 16, thus forming a stable support frame around the rotating part 3. This multi-point support structural layout effectively disperses the load and torque generated during the operation of the rotating shaft, enabling the rotating part 3 to remain stable throughout the operation process. In practical applications, the configuration of the three connecting arms 15 improves the fixing stability of the rotating part 3. Due to the increase in the number of connecting arms 15, the contact area and the number of support points of the rotating part 3 on the structural object also increase accordingly.

[0030] The fixing plate 1, the shaft rod 2 and the rotating part 3 of the present utility model are all made of stainless steel. The application of stainless steel as the material has significant advantages in these components, not only improving the durability of the entire rotating shaft system but also enhancing its reliability under various environmental conditions. In an industrial environment, the rotating shaft is often exposed to the influence of moisture or corrosive substances. Using stainless steel as the material can effectively prevent structural deterioration or performance degradation caused by corrosion. Even in a high-humidity or chemically corrosive environment, the corrosion-resistant characteristics of stainless steel can maintain the structural integrity and functional stability of the fixing plate 1, the shaft rod 2 and the rotating part 3, ensuring the long-term operation of the rotating shaft in a harsh environment. Stainless steel has excellent mechanical properties, including high strength and toughness. The fixing plate 1, the shaft rod 2 and the rotating part 3 need to bear certain mechanical stresses and loads during the operation of the rotating shaft. The high strength of stainless steel can ensure that these components will not deform or break due to excessive load during operation. In addition, the toughness of stainless steel can effectively absorb and disperse the impact force and vibration generated during the operation process, further improving the working stability and durability of the rotating shaft.
