[0014] An air guide device for cold storage, such as Figure 1 、 2 As shown, it includes an air inlet pipe 1 and an air outlet pipe 2, and the air inlet pipe 1 and the air outlet pipe 2 are connected and arranged, and is characterized in that: a spherical shell 3 is fixedly provided between the air inlet pipe 1 and the air outlet pipe 2, and an air inlet 4 and an air outlet 5 are opened on the left and right sides of the spherical shell 3 in sequence, a bellows 6 is fixedly installed on the air inlet 4, and the air outlet pipe 2 is fixedly installed on the air outlet 5, and the outer periphery of the spherical shell 3 is provided with a first arc ring 7 and a second arc ring 8, and the first arc ring 7 and the second arc ring 8 can respectively slide in contact with the outer periphery of the spherical shell 3, and an annular rubber pad 9 is fixedly installed on the inner periphery of the second arc ring 8. 8 is fixedly mounted on a housing 10, a second annular ring 8 is fixedly mounted in a reserved hole provided on the housing 10, a first through-groove 11 is provided on one side of the housing 10, an air inlet pipe 1 is rotatably mounted on the first through-groove 11, one side of the air inlet pipe 1 is rotatably mounted on the first through-groove 11 via a bearing, one end of the air inlet pipe 1 is connected to one end of the corrugated pipe 6, a spring rod 12 is fixedly mounted on both sides of the housing 10, the fixed ends of the spring rod 12 are fixedly mounted on the upper and lower sides of the inner wall of the housing 10 via a connecting rod, and the movable ends of the spring rod 12 are fixedly connected to both sides of the first arcuate ring 7 via a connecting rod. The utility model has a simple structure and an ingenious design. By controlling the rotation of the spherical housing 3, the air outlet pipe 2 can be adjusted not only 360 degrees in the axial direction but also within a certain radial range, thereby increasing the wind direction guide angle and improving the cooling effect. The utility model is simple to operate, can meet market demand, and is suitable for promotion. When the utility model is used, the device is first placed at the air outlet of the cold storage fan, and the air outlet of the cold storage fan is aligned with the first through-groove 11 by the clamping mechanism, the fan is started, and the direction of the air outlet pipe 2 is adjusted according to the position of the items placed in the cold storage, and the spherical shell 3 is pushed leftward. The spherical shell 3 drives the first arc ring 7 to move left and separate from the second arc ring 8. The spring rod 12 and the bellows 6 are compressed. At this time, the spherical shell 3 is rotated again to adjust the angle, and the spherical shell 3 drives the bellows 6 and the air inlet pipe 1 to rotate. The spherical shell 3 and the first arc ring 7 slide relative to each other. After adjusting to a certain angle, the spherical shell 3 is released. The spherical shell 3 moves to the right under the action of the spring rod 12 into the annular rubber pad 9. Under the action of friction, the spherical shell 3 can maintain the adjusted angle unchanged and improve the sealing between the spherical shell 3 and the second arc ring 8, so that the cold air flowing out through the air outlet pipe 2 can maintain a certain angle to cool the surface of the items placed in the cold storage, thereby improving the cooling effect.

[0015] Specifically, as shown in the figure, one side of the first through groove 11 of this embodiment is fixedly provided with a clamping mechanism that can fix the box body 10 on the cold storage fan. The clamping mechanism includes several screw rods 20. The threads at both ends of the screw rod 20 are rotated in opposite directions. The screw rods 20 are rotatably installed on both sides of the box body 10. Several shaft seats are fixedly installed on both sides of the box body 10. The same screw rod 20 is rotatably installed in the corresponding two shaft seats. The two ends of the screw rod 20 are respectively threaded to fit the nut 21. The nut 21 can only move up and down on the corresponding screw rod 20. Slide grooves are respectively provided on both sides of the box body 10, and sliders are respectively installed in the slide grooves for sliding cooperation. One side of the slider is fixedly connected to one side of the corresponding nut 21. Support rods 22 are respectively fixedly installed on the nut 21, and limit plates 23 are respectively fixedly installed on the inner sides of the corresponding support rods 22. Place the air outlet of the cold storage fan at the position of the first through slot 11, rotate the screw rods 20 on both sides forward, the screw rods 20 drive the nuts 21 on both sides to move toward the middle, and the nuts 21 drive the support rods 22 and the limit plates 23 to move toward the middle. When the limit plates 23 clamp the fan casing, stop rotating the screw rods 20. At this time, the cold storage fan is fixed at the position of the first through slot 11, which speeds up the installation efficiency.

[0016] Specifically, as shown in the figure, an air guide housing 13 is fixedly mounted on one end of the air outlet duct 2 in this embodiment. One side of the air guide housing 13 is open, and a second through-hole 14 is formed on the other side of the air guide housing 13. The second through-hole 14 is connected to the air outlet duct 2. A plurality of air guide plates 30 are provided on one side of the second through-hole 14. The air guide plates 30 are fixedly mounted on the air guide housing 13 at an angle. The plurality of air guide plates 30 are symmetrically distributed front to back, with the left ends of the air guide plates 30 close to each other and the right ends away from each other. The air guide plates 30 have the function of dispersing wind. The wind from the second through-hole 14 can be dispersed by the air guide plates 30, so that it is blown out more evenly from the right side of the air guide housing 13.

[0017] Furthermore, as shown in the figure, one end of the screw rod 20 of this embodiment is fixedly mounted with a hand wheel 40. Rotating the screw rod 20 by rotating the hand wheel 50 is more convenient and labor-saving.
