[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are 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 shall fall within the scope of protection of the present invention.

[0023] Example 1

[0024] See Figure 1 、 Figure 2 , a gas path direction rotation adjustment device, including a shell, a rotating shaft 1, a flange bearing 4, a limit block 5, a ball plunger 6, a pipe joint 7, and an air pipe 8. The rotating shaft 1 is rotatably connected in the shell through two flange bearings 4. In this embodiment, taking a rotating shaft 1 as an example, the rotating shaft 1 is circumferentially provided with multiple gas path interfaces 102, and the line connecting the midpoints of the multiple gas path interfaces 102 is parallel to the axis of the rotating shaft. An opening is provided at one end of the rotating shaft 1, in which an air path channel is provided. The opening is connected to the multiple air path interfaces 102 through the air path channel. The pipe joint 7 includes a fixed end 71 and a rotating end 72. The rotating end 72 is rotatably connected to the fixed end 71, and the rotating end 72 is fixedly connected to the rotating shaft 1. In this embodiment, a threaded connection is taken as an example, and the fixed end 71 is connected to the air path channel and the air path interface 102 through an opening; the pipe joint 7 in this embodiment can adopt a commercially available right-angle terminal tube 360 ​​rotary joint, model YPN-Lφ8-G1 / 8;

[0025] The fixed end 71 of the pipe joint 7 is connected to the air pipe 8, which is connected to the air source, and the gas is transported to the rotating shaft 1 through the air pipe 8. A plurality of limiting holes 101 are also formed circumferentially at both ends of the rotating shaft 1. The limiting holes 101 are distributed at equal angles along the circumference of the rotating shaft 1. A limiting block 5 is fixedly connected to the shell. The limiting block 5 is located on the outside of the rotating shaft 1, and a ball plunger 6 is provided on the side facing the limiting hole 101. The ball plunger 6 includes a ball head and a spring. A concave hole adapted to the ball head is opened in the limiting block 5, and the ball head is elastically connected to the inner wall of the concave hole through a spring, wherein part of the ball head and the spring are located in the concave hole, and the limiting hole 101 is adapted to the shape of the ball head.

[0026] See Figure 1 、 Figure 3 The housing includes a bottom mounting plate 2 and a side mounting plate 3. Two side mounting plates 3 are fixedly connected to the bottom mounting plate 2. The limit block 5 is fixedly connected to the bottom mounting plate 2 by bolts. A side mounting hole 301 is opened on the side mounting plate 3. The flange bearing 4 rotatably cooperates with the side mounting plate 3 through the side mounting hole 301. The rotating shaft 1 can rotate relative to the side mounting plate 3, thereby changing the gas outlet direction of the gas path interface 102.

[0027] The gas circuit interface 102 is connected to male and female gas nozzles. The female gas nozzle 10 can be the old aerospace oxygen inhalation terminal YF-LHTBTJT-YTS purchased on the market, and the male gas nozzle 11 can be the pagoda plug YF-LHTBT-02. Among them, the female gas nozzle 10 is fixedly connected to the gas circuit interface 102, and the male gas nozzle 11 and the female gas nozzle 10 are detachably connected. The male gas nozzle 11 and the female gas nozzle 10 are connected after being plugged into each other, and are not connected after the male gas nozzle 11 is unplugged. The male gas nozzle 11 is connected to the air pipe 8. In this embodiment, there are three gas circuit interfaces 102. Adjusting the air outlet direction of the gas circuit interface 102 can save the length of the air pipe 8 and avoid crossing of the connected air pipes 8, effectively saving the air path, improving the smoothness of the air path, and increasing the gas utilization rate.

[0028] Working principle:

[0029] When the ball plunger 6 is in use, the spring can expand and contract as the force changes, and the spring drives the ball head to expand and contract synchronously. When the rotating shaft 1 is fixed, the ball head is stuck in the limiting hole 101, limiting the position of the rotating shaft 1 so that it will not rotate; when the rotating shaft 1 is manually rotated, due to the change in force, the ball head is retracted into the ball plunger 6, and the rotating shaft 1 can rotate. When passing through the limiting hole 101 at another angle, the ball head of the ball plunger 6 pops out to limit the position again.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that, in this embodiment, two rotating shafts 1 are provided, and the two rotating shafts 1 are arranged side by side. Of course, they can also be set to three. By adjusting the number and setting position of the rotating shafts 1, different air path interfaces 102 can be partitioned. The shell also includes a top cover 9, and the top cover 9 is fixedly connected to the bottom mounting plate 2 and the side mounting plate 3. The top cover 9 is provided with an L-shaped waist hole groove for rotating the male air nozzle 11 and the female air nozzle 10. Since there are two rotating shafts 1, the air pipe 8 is connected to the two rotating shafts 1 through two pipe joints 7 respectively. One pipe joint 7 is a right-angle terminal pipe 360 ​​rotary joint, model YPN-Lφ8-G1 / 8, and the other pipe joint 7 is a three-way quick-tighten pipe joint, model YPN-Eφ8-G1 / 8.
