Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to the attached Figures 1-3 description, it includes an air shaft body 1. A rotating shaft handle 2 is fixedly connected to the side of the air shaft body 1. A rotating rod 3 is arranged on the side of the rotating shaft handle 2. A placement groove 4 is opened inside the rotating rod 3. The rotating shaft handle 2 is placed inside the placement groove 4. A first moving groove 5 is opened inside the rotating shaft handle 2. A first spring 6 is arranged inside the first moving groove 5. A second moving groove 8 is opened inside the placement groove 4. The first moving groove 5 passes through and is inserted into the second moving groove 8. A second spring 9 is arranged inside the second moving groove 8. A pressing rod 10 is arranged inside the second moving groove 8. When it is necessary to disassemble, replace or repair the rotating shaft handle 2 and the air shaft body 1, the pressing rod 10 can be pressed. The pressing rod 10 drives the extrusion of the limiting block 7. When the limiting block 7 is displaced and separated from the second moving groove 8, the placement groove 4 and the rotating shaft handle 2 can be released from the limit, and then the effect of rapid disassembly can be achieved, so that the air shaft body 1 can be quickly disassembled, achieving the effect of convenient replacement and repair.

[0024] Then, three groups of the first moving groove 5, the first spring 6, the limiting block 7, the second moving groove 8, the second spring 9 and the pressing rod 10 are arranged on the placement groove 4. Through the effect of the three pressing rods 10, the rotating shaft handle 2 is more stable when fixed on the rotating rod 3.

[0025] Subsequently, one end of the second spring 9 is fixedly connected to the second moving groove 8, and the other end of the second spring 9 is fixedly connected to the pressing rod 10. One end of the first spring 6 is fixedly connected to the limiting block 7, and the other end of the first spring 6 is fixedly connected to the first moving groove 5. Through this mechanism, the operator can use the elastic properties of the second spring 9 and the first spring 6 to reset the pressing rod 10 and the limiting block 7 without being affected by external forces, achieving the limiting effect of the limiting block 7 on the second moving groove 8.

[0026] Next, the inner wall of the placement groove 4 is in mutual contact with the outer wall of the rotating shaft handle 2. Through this structure, the rotating shaft handle 2 is more stable when fixed in the placement groove 4, and can be more smooth when the rotating shaft handle 2 is disengaged.

[0027] Then, the outer wall of the pressing rod 10 is provided with anti-slip lines. When pressing the pressing rod 10, it has a certain anti-slip effect to prevent operation failure.

[0028] It should be noted that a buffer pad 11 is fixedly sleeved on the outer wall of the pressing rod 10, and a buffer groove 12 is arranged inside the buffer pad 11. The design of this structure enables when the air shaft body 1 is running, when the air shaft body 1 is impacted, the existence of the buffer groove 12 and the buffer pad 11 can effectively relieve the impact force, thus achieving a shock-absorbing effect. Specifically, the pressing rod 10 can drive the internal limiting block 7 to disengage from the limit of the second moving groove 8 through the pressing operation, so that the limit between the rotating shaft handle 2 and the rotating rod 3 is released, facilitating the operator to perform quick disassembly. This design not only improves the operation convenience of the equipment, but also enhances the absorption and buffering ability of the impact force during use;

[0029] In terms of the working principle, when the air shaft body 1 is impacted by an external force during operation, the impact force first acts on the buffer pad 11. The material of the buffer pad 11 has certain elasticity and toughness, which can initially absorb part of the impact force. Then, the impact force is transmitted to the buffer groove 12. The design of the buffer groove 12 enables it to deform when impacted, further absorbing and dispersing the impact force, thereby reducing the force directly acting on the air shaft body 1. This buffering process effectively protects the air shaft body 1, reduces damage and wear caused by impact, and extends the service life of the equipment. In addition, the anti-slip line design on the outer wall of the pressing rod 10 provides better hand feeling and operation stability during the pressing operation, preventing operation failure;

[0030] Among them, the design of the gas expansion shaft body 1 integrates multiple functional components. Through the mutual cooperation of the pressing rod 10, the buffer pad 11 and the buffer groove 12, the buffer function of the equipment in operation is realized, while ensuring the simplicity of operation and the rapidity of disassembly. In the specific implementation, the side of the gas expansion shaft body 1 is fixedly connected with a rotating shaft handle 2, and the rotating shaft handle 2 is connected to the gas expansion shaft body 1 through a rotating rod 3. A placement groove 4 is opened inside the rotating rod 3. The rotating shaft handle 2 is placed inside the placement groove 4, and the limiting function is realized by the first moving groove 5, the first spring 6, the second moving groove 8 and the second spring 9. By pressing the pressing rod 10, the pressing rod 10 drives the limiting block 7 to disengage from the second moving groove 8, thereby releasing the limit between the rotating shaft handle 2 and the rotating rod 3, and realizing quick disassembly. This design not only improves the operating efficiency of the equipment, but also effectively alleviates the impact force in operation through the structure of the buffer pad 11 and the buffer groove 12, thereby enhancing the durability and reliability of the equipment;

[0031] In summary, the design of the air expansion shaft device achieves a shock-absorbing effect through the buffer pad 11 and the buffer groove 12. At the same time, combined with the anti-slip design of the pressing rod 10 and the convenient disassembly function, the equipment is safer and more efficient in operation. This design not only meets the needs of modern coating machines for efficient, safe and convenient operation of air expansion shaft devices, but also improves the service life and reliability of the equipment to a certain extent, providing a more complete solution for the coil processing industry.
