[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a coaxial valve switch self-switching mechanism, including a base 1, a switch mechanism 2 fixedly mounted on the upper surface of the base 1, and mounting mechanisms 3 on both sides of the switch mechanism 2. The switch mechanism 2 includes a cylinder 20, the lower surface of which is fixedly connected to the base 1. A front cover 26 and a rear cover 21 are respectively provided at both ends of the cylinder 20. A valve seat 22 is fixedly mounted on the inner side of the rear cover 21. A front air hole 27 and a rear air hole 28 are opened on the upper surface of the cylinder 20. A control tube 25 is slidably mounted on the inner side of the cylinder 20. A spring 24 is sleeved on the outer side of the control tube 25. A valve core 23 is fixedly mounted on the outer side of the control tube 25. When using the switch mechanism 2, it is first fixedly mounted in the working position by the base 1. When it is necessary to switch the fluid or gas passage, an external force is applied to the control tube 25, causing it to slide along the sliding groove 29 on the inner side of the cylinder 20. The sliding of the control tube 25 causes the valve core 23, which is fixedly mounted on its outer side, to move together, thereby changing the relative position between the valve core 23 and the valve seat 22, which is fixedly mounted on the inner side of the rear cover 21, thus opening or closing the passage. At the same time, the spring 24 sleeved on the outer side of the control tube 25 provides corresponding elastic force according to the direction of movement of the control tube 25, ensuring that the valve core 23 can accurately and quickly return to the initial position or remain in the working position. During the switching process, the front air hole 27 and the rear air hole 28 opened on the upper surface of the cylinder body 20 serve as the inlet and outlet of fluid or gas, ensuring smooth passage.

[0018] The mounting mechanism 3 includes two mounting plates 30. One side of each mounting plate 30 is fixedly connected to one side of the front cover 26 and the rear cover 21, respectively. Multiple mounting rods 36 arranged in a rectangular array are slidably mounted on both mounting plates 30. Each end of a mounting rod 36 is threaded with a fastening nut 32. A fixing bracket 33 is provided on the outer side of both the front cover 26 and the rear cover 21, and the fixing bracket 33 is fixedly engaged with the base 1. Using the mounting mechanism 3, firstly, the two mounting plates 30 are fixedly connected to one side of the front cover 26 and the rear cover 21, respectively. Then, the multiple mounting rods 36 arranged in a rectangular array are slidably inserted through the mounting holes 31 on one side of the mounting plates 30, ensuring that the mounting rods 36 can slide freely and adapt to different installation requirements. Next, fastening nuts 32 are threaded onto both ends of the mounting rods 36, and the position of the mounting rods 36 is fixed by tightening the fastening nuts 32, thereby achieving a stable connection between the mounting mechanism 3 and the switching mechanism 2. Finally, the fixing brackets 33 on the outer side of the front cover 26 and the rear cover 21 are fixedly engaged with the base 1, and the fixing brackets 33 are connected to the corresponding structures on the base 1 through the fixing holes 34 on the lower surface of the fixing brackets 33, so as to ensure the stability and reliability of the entire coaxial valve switch self-switching mechanism.

[0019] The sliding grooves 29 formed at both ends of the cylinder 20 slide in conjunction with the control tube 25. This design ensures the stability and smoothness of the control tube 25 during sliding, effectively reducing friction and wear, and improving the service life and reliability of the switching mechanism 2. Multiple rectangular arrayed fixing grooves 35 on the upper surface of the base 1 provide more mounting points and fixing methods for the entire mechanism, enhancing its stability and adaptability.

[0020] Multiple mounting holes 31 on one side of the mounting plate 30 slide with the mounting rod 36, making the installation process more flexible and convenient, while ensuring a stable connection between the mounting mechanism 3 and the switching mechanism 2. Sealing grooves 37 are provided at both ends of the cylinder body 20 and on one side of the front cover 26 and the rear cover 21, and sealing rings 38 are provided inside each pair of sealing grooves 37, effectively improving the sealing performance of the mechanism, preventing fluid or gas leakage, and ensuring the normal operation of the mechanism. Fixing holes 34 on the lower surface of the fixing bracket 33 are fixedly engaged with the base 1, further enhancing the stability and reliability of the entire mechanism, enabling the coaxial valve switching mechanism to operate stably in various harsh environments.

[0021] Working Principle: When using the switching mechanism 2, it is first securely installed in the working position via the base 1. When it is necessary to switch the fluid or gas passage, an external force is applied to the control pipe 25, causing it to slide along the sliding groove 29 on the inner side of the cylinder body 20. The sliding of the control pipe 25 will cause the valve core 23 fixedly mounted on its outer side to move together, thereby changing the relative position between the valve core 23 and the valve seat 22 fixedly mounted on the inner side of the rear end cover 21, realizing the opening or closing of the passage. At the same time, the spring 24 sleeved on the outer side of the control pipe 25 will provide corresponding elastic force according to the direction of movement of the control pipe 25, ensuring that the valve core 23 can accurately and quickly return to the initial position or remain in the working position. During the switching process, the front air hole 27 and the rear air hole 28 opened on the upper surface of the cylinder body 20 serve as the inlet and outlet of the fluid or gas, ensuring the smooth flow of the passage.

[0022] First, using the mounting mechanism 3, two mounting plates 30 are fixedly connected to one side of the front cover 26 and the rear cover 21, respectively. Then, multiple mounting rods 36 arranged in a rectangular array are slidably inserted through the mounting holes 31 on one side of the mounting plates 30, ensuring that the mounting rods 36 can slide freely and adapt to different installation requirements. Next, fastening nuts 32 are threaded onto both ends of the mounting rods 36, and the position of the mounting rods 36 is fixed by tightening the fastening nuts 32, thereby achieving a stable connection between the mounting mechanism 3 and the switching mechanism 2. Finally, the fixing brackets 33 provided on the outer sides of the front cover 26 and the rear cover 21 are fixedly engaged with the base 1, and connected to the corresponding structure on the base 1 through the fixing holes 34 on the lower surface of the fixing brackets 33, ensuring the stability and reliability of the entire coaxial valve switching mechanism.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
