[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 8 The utility model provides a pneumatic actuator suitable for docking different air pipes, including an actuator body 1 and an air source connector 2 connected to the side of the actuator body 1, and the air source connector 2 is provided with two air source interfaces 6. The air source connector 2 is connected to an adapter 3, and the adapter 3 is provided with two docking interfaces 4, and the docking interfaces 4 are in communication with the corresponding air source interfaces 6. The bottom of the adapter 3 is connected to two L-shaped plates 10, and the two L-shaped plates 10 are relatively distributed. The actuator body 1 is connected to a positioning mechanism for positioning the L-shaped plate 10, and the positioning mechanism includes two U-shaped seats 9, two positioning columns 13, two springs 14, and an arc plate 8. The positioning column 13 passes through the top of the U-shaped seat 9, and one end of the positioning column 13 is connected to the arc plate 8, and the other end matches the L-shaped plate 10. The spring 14 is used to drive the arc plate 8 to move in a direction close to the U-shaped seat 9. The arc plate 8 is connected to a guide mechanism for guiding the arc plate 8.

[0026] Different sizes of adapters 3 can be processed according to the size of the trachea to match the docking port 4.

[0027] After selecting the adapter 3 of the corresponding size, the adapter 3 is connected to the gas source connector 2, and then the adapter 3 is rotated, which synchronously drives the two L-shaped plates 10 to rotate, so that the L-shaped plates 10 are inserted into the U-shaped seat 9, and the positioning column 13 is pushed up and pressed tightly against the positioning groove 20 of the L-shaped plate 10. At this time, the spring 14 and the spring 2 17 are both in an extended state, which can not only realize the positioning of the adapter 3, but also improve the tightness of the connection between the adapter 3 and the gas source connector 2, making it easier to install the adapter 3.

[0028] The positioning mechanism also includes two second bevels 19, located at the bottom of positioning post 13 and matching bevel 18 at the end of L-shaped plate 10. As adapter 3 rotates, bevels 18 and 19 slide relative to each other, lifting positioning post 13. This gradually stretches springs 14 and 17 until the bottom of positioning post 13 connects with positioning slot 20, at which point adapter 3 stops moving, effectively positioning and securing L-shaped plate 10 and limiting the position of adapter 3.

[0029] The L-shaped plate 10 is provided with a positioning groove 20 , which matches the end of the positioning column 13 .

[0030] The spring 14 is sleeved on the positioning column 13 , and both ends of the spring 14 are connected to the arc plate 8 and the U-shaped seat 9 , and the U-shaped seat 9 is connected to the actuator body 1 .

[0031] There are two guide mechanisms, including a guide cylinder 15, a guide post 16, and a second spring 17. The guide cylinder 15 is connected to the actuator body 1. One end of the guide post 16 is slidably connected to the guide cylinder 15, and the other end is connected to the curved plate 8. The second spring 17 is used to drive the curved plate 8 toward the guide cylinder 15. When the first inclined surface 18 and the second inclined surface 19 slide relative to each other, the upward movement of the positioning post 13 can simultaneously drive the curved plate 8 upward. The guide post 16 also moves upward synchronously, and the second spring 17 is stretched. The guide post 16 can ensure the stable raising and lowering of the curved plate 8, providing a good guiding effect.

[0032] The second spring 17 is sleeved on the guide column 16 , and both ends of the second spring 17 are connected to the guide cylinder 15 and the arc plate 8 .

[0033] The end of the gas source connector 2 is provided with a groove 12, into which a sealing ring 11 is connected. The outer side of the gas source connector 2 is provided with a sealing surface 7, which is an annular inclined surface. When the adapter 3 is installed, the adapter 3 is pressed tightly against the sealing ring 11 and sealing surface 7, improving the sealing between the adapter 3 and the gas source connector 2, achieving a double sealing effect, preventing air leakage, and ensuring safe and reliable use.

[0034] The adapter 3 is provided with an air flow channel 5 , which is connected to the docking port 4 and the air source port 6 .

[0035] Working principle: After selecting the appropriate adapter 3, the adapter 3 is connected to the gas source connector 2, and then rotating the adapter 3 can synchronously drive the two L-shaped plates 10 to rotate. The L-shaped plate 10 is gradually inserted into the U-shaped seat 9, and the inclined surface 18 and the inclined surface 2 19 slide relative to each other, which can gradually lift the positioning column 13. The upward movement of the positioning column 13 drives the arc plate 8 to move upward. At this time, the spring 14 and the spring 2 17 are gradually stretched. Until the bottom of the positioning column 13 is connected to the positioning groove 20 of the L-shaped plate 10, the L-shaped plate 10 can be limited, and the stability of the connection between the adapter 3 and the gas source connector 2 is improved. Combined with the use of the sealing ring 11 and the sealing surface 7, a double sealing effect is achieved, which improves the tightness of the connection between the adapter 3 and the gas source connector 2. Then the air pipe is docked with the docking port 4, which is convenient for the use of the actuator. When the adapter 3 needs to be disassembled, the arc-shaped plate 8 can be lifted, and the two positioning posts 13 can be moved upward synchronously to separate the bottom of the positioning posts 13 from the positioning grooves 20, thereby loosening the L-shaped plate 10. Then, the adapter 3 can be rotated to synchronously drive the two L-shaped plates 10 to move back, thereby loosening the adapter 3, making it easy to disassemble and replace the adapter 3 with high efficiency.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
