[0021] Specifically, the throttle hole adjusting member 6 is connected to the inside of the liquid outlet pipe 5 by sliding, and the depth of the throttle hole adjusting member 6 inserted into the throttle hole tube 4 is controlled, thereby controlling the size of the liquid outlet hole at one end of the throttle hole tube 4, thereby achieving the ability to adjust the throttling size of the throttle according to demand, thereby improving the practicality of the throttle.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the throttle structure of the automobile air conditioner of the present invention has a T-shaped groove 12 on both sides of the inner wall of the liquid outlet pipe 5, a T-shaped slider 13 is slidably connected between the two T-shaped grooves 12, and fixed blocks 7 are fixedly installed on the sides of the two T-shaped sliders 13. The two fixed blocks 7 are fixedly connected to the two sides of the throttle hole adjustment member 6.

[0023] One of the T-shaped slide grooves 12 has a screw 14 rotatably connected to both sides of the inner wall. The screw 14 is threadedly connected to the middle part of the T-shaped slider 13. One end of the screw 14 is fixedly installed with a second bevel gear 16. One side of the bottom end of the T-shaped slide groove 12 is rotatably connected to a rotating rod 17. The end of the rotating rod 17 is fixedly installed with a first bevel gear 15. The first bevel gear 15 is meshed with the second bevel gear 16.

[0024] Specifically, the first bevel gear 15 is driven to rotate by the rotating rod 17, and the first bevel gear 15 is engaged with the second bevel gear 16, thereby realizing the rotation of the screw 14, and the rotation of the screw 14 drives the movement of the T-shaped slider 13, and the movement of the T-shaped slider 13 drives the movement of the throttle hole adjustment member 6.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the throttle structure of the automobile air conditioner of the utility model has a valve plate 10 rotatably connected to the middle of the regulating valve 9, a valve stem 11 rotatably connected to the top of the liquid outlet pipe 5, and a bottom end of the valve stem 11 is fixedly connected to the top end of the valve plate 10.
