[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figures 1 to 3As shown, a simple valve shaft structure is applied to a simple valve. The simple valve is a simple and easy-to-use switch valve, which is a valve body structure. The simple valve includes a valve body, a valve seat connected to the valve body, a valve core arranged in the valve body, and a simple valve shaft structure that can be rotatably mounted on the valve seat and connected to the valve core. The shaft structure of the simple valve includes a shaft body 1 and a connector 2; the shaft body 1 and the connector 2 are made by cold heading integral molding process.

[0025] The rotating shaft structure of the simple valve is combined by setting a rotating shaft body 1 and a connecting piece 2, and the rotating shaft body 1 and the connecting piece 2 are made by a cold heading integrated forming process, that is, in production, at room temperature, an external force is applied to the metal to form the metal in a predetermined mold. The rotating shaft structure of the simple valve is made by a cold heading integrated forming process. The rotating shaft structure of the simple valve has the characteristics of simple structure, good mechanical properties, simplified manufacturing process, low cost, and convenient assembly. It solves the assembly difficulty and easy loosening problems in the traditional split-type rotating shaft design, can further optimize the product structure, reduce the number of components, improve the overall performance of the product, and improve the overall strength and stability of the rotating shaft structure. It can effectively resist external impact and vibration, which is conducive to extending the service life of the rotating shaft structure of the simple valve, reducing production costs and maintenance difficulties, and has important practical value and promotion significance.

[0026] In this embodiment, the connector 2 includes a snap-fitting portion 21 and a limiting plate 22; the snap-fitting portion 21 is adapted to be snap-fitted with the snap-fitting groove on the valve core of the simple valve to realize a detachable connection between the rotating shaft structure of the simple valve and the valve core, and the structural connection is stable and easy to disassemble and assemble. The rear end of the snap-fitting portion 21 is connected to the front end of the limiting plate 22; the rear end of the limiting plate 22 is connected to the front end of the rotating shaft body 1. The purpose of the limiting plate 22 is to prevent the connector 2 from being installed too far, and to play a good limiting role, preventing the connector 2 from sliding out of the valve seat of the simple valve along with the rotating shaft body 1.

[0027] Ensure that the rotating shaft body 1 can maintain a stable position and angle during the rotation process. By setting the embedded part 21 and the limit plate 22 to form a connecting member 2, the connecting member 2 is convenient for detachable connection with the valve core, the structure is simple, the disassembly and assembly are convenient, and the installation and maintenance are simpler. In another embodiment, the connecting member 2 can be a screw part, and the screw part can be adapted and connected with the screw hole on the valve core of the simple valve to realize the detachable connection between the rotating shaft structure of the simple valve and the valve core, and the structural connection is stable and the disassembly and assembly are convenient.

[0028] Preferably, the upper and lower ends of the circumference of the clamping part 21 are arranged in planes; the left and right sides of the circumference of the clamping part 21 are arranged in arc surfaces. By arranging the clamping part 21 in this way, it is convenient to fit the clamping groove on the valve core of the simple valve for clamping connection. The circumference of the clamping part 21 is designed as a plane and an arc surface, and the structural connection is more stable and reliable.

[0029] In this embodiment, the limit plate 22 is in the shape of a circular plate; the shaft body 1 is in the shape of a cylinder. The limit plate 22 and the shaft body 1 are designed in this way to facilitate the shaft structure of the simple valve to rotate on the simple valve to open the valve for ignition. The diameter of the limit plate 22 is larger than the diameter of the shaft body 1. The limit plate 22 and the shaft body 1 are reasonably designed and limited to avoid the structure being too large or too small. Of course, the shape and size of the shaft body 1 can also be adjusted. For example, the length of the shaft body 1 can be increased or its cross-sectional shape can be changed to accommodate alpine gas tanks of different specifications. At the same time, the design of the connector 2 can also be adjusted accordingly to adapt to different installation environments and requirements.

[0030] In order to facilitate the rotation of the shaft body 1 and achieve a good effect of opening or closing the simple valve, a notch positioning groove 11 is provided on the rear end of the shaft body 1; the notch positioning groove 11 is opened from the rear end surface of the shaft body 1 to the front end surface of the shaft body 1; the notch positioning groove 11 is an inverted L-shaped groove structure. By providing the notch positioning groove 11, it is convenient to add a knob structure, which is matched with the shaft body 1 to achieve the effect of stable sleeve connection on the shaft body 1.

[0031] Preferably, the length of the notch positioning groove 11 is less than or equal to the length of the shaft body 1. In particular, when the length of the notch positioning groove 11 is equal to the length of the shaft body 1, the connection between the additional knob structure and the shaft body 1 is more stable and reliable.

[0032] In order to achieve a better assembly effect and a more stable structure between the shaft body 1 and the added knob structure, the angle between the rear end surface of the shaft body 1 and its peripheral side surface is rounded.

[0033] In the present embodiment, the rotating shaft body 1 and the connecting member 2 are both made of the same high-strength material. By designing the rotating shaft body 1 and the connecting member 2 in this way, the strength and wear resistance of both can be enhanced, and the overall strength and stability of both can be improved. Preferably, the high-strength material is iron. Iron has high strength and good toughness, which enables the iron rotating shaft body 1 and the connecting member 2 to withstand large loads and torques, ensuring the stable operation of the structure. At the same time, the iron rotating shaft structure is not prone to breakage or deformation when subjected to impact or external force, and has high impact resistance. Moreover, iron, as a common metal material, has good processing properties, and users can process iron into the rotating shaft structure of the simple valve through casting and other process means according to demand. In addition, iron is widely available and relatively cheap, which helps to reduce the production cost of the rotating shaft structure of the simple valve and improve the market competitiveness of the product.

[0034] In addition, the shaft structure of the simple valve can be further optimized. For example, an anti-slip texture can be set on the surface of the shaft body 1 to increase friction and prevent slipping during use. At the same time, a limit structure can be set on the connector 2 to prevent the valve from slipping.

[0035] In summary, the embodiment of the utility model provides a shaft structure of a simple valve, wherein the shaft structure of the simple valve is combined by setting a shaft body 1 and a connecting piece 2, and the shaft body 1 and the connecting piece 2 are made by a cold heading integrated molding process, specifically by a mold method, that is, in production, at room temperature, an external force is applied to the metal to form the metal in a predetermined mold. The shaft structure of the simple valve is made by a cold heading integrated molding process, and the shaft structure of the simple valve has the characteristics of simple structure, good mechanical properties, simplified manufacturing process, low cost, and convenient assembly, which solves the assembly difficulty and easy loosening problems in the traditional split shaft design, can further optimize the product structure, reduce the number of components, improve the overall performance of the product, and improve the overall strength and stability of the shaft structure, can effectively resist external impact and vibration, and is conducive to extending the service life of the shaft structure of the simple valve, reducing production costs and maintenance difficulties, and has important practical value and promotion significance.

[0036] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
