[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a movable and adjustable cold storage air outlet device, comprising a plurality of air ducts 1 connected in series to the air outlet end of the refrigerator, a plurality of circular holes 1.1 are arranged in the middle of the bottom plate of the air duct 1 along its axial direction, and a plurality of sleeve holes 1.2 are arranged in the circumferential direction at the position of the bottom plate of the air duct 1 located outside the circular holes 1.1; and a slide rail 1.3 is fixed to the front and rear ends of the bottom surface of the air duct 1 along its axial direction. Among them, connecting flanges 1.4 are arranged at both ends of the air duct 1, and a plurality of connecting frames 1.5 are fixed to the top of the front and rear walls of the air duct 1, that is, a plurality of air ducts 1 are connected to each other through the connecting flanges 1.4 in combination with suture bolts, and the connecting frame 1.5 is fixed to the top plate in the cold storage room with expansion bolts, so as to facilitate the fixed installation of the air duct 1.

[0028] The inner cavity of the air duct 1 is provided with a circular plugging plate 2 covering the circular hole 1.1, wherein a plurality of guide posts 2.1 which are slidably sleeved and matched with the sleeve hole 1.2 are vertically fixed to the outer edge of the bottom surface of the circular plugging plate 2. This facilitates the circular plugging plate 2 to be smoothly lifted upward from the bottom of the circular hole 1.1; in addition, a limiting ring is provided at the bottom end of the guide post 2.1 to prevent the guide post 2.1 from being separated from the sleeve hole 1.2.

[0029] The sliding seat 3 comprises a horizontal support plate 3.1, a slider 3.3 fixed at the four corners of the top surface of the horizontal support plate 3.1 and slidably mounted on the slide rail 1.3, and an internally threaded cylinder 3.2 with a top fixedly sleeved in the middle of the horizontal support plate 3.1 and extending vertically.

[0030] The top thread of the external threaded cylinder 4 is sleeved in the internal threaded cylinder 3.2, and the top of the external threaded cylinder 4 is movably sleeved and matched with the circular hole 1.1. The top of the wall of the external threaded cylinder 4 is provided with a plurality of opening grooves 4.1 along the circumferential direction.

[0031] The swing air outlet mechanism 5 comprises a sleeve 5.2 with its top end rotatably mounted on the outside of the bottom end of the external threaded cylinder 4, a horizontal tube 5.1 fixedly connected to the bottom end of the side wall of the sleeve 5.2 in the radial direction, and an air outlet cover 5.3 with its top end fixedly connected to the horizontal tube 5.1 away from the bottom surface of one end of the sleeve 5.2 and opening downward.

[0032] In summary, when the air outlet position of the cold storage air outlet device needs to be adjusted, first move the sliding seat 3 relative to the air duct 1. When the sliding seat 3 moves horizontally, the slider 3.3 slides along the slide rail 1.3 until the top of the external threaded cylinder 4 is opposite to the corresponding circular hole 1.1. At this time, the external threaded cylinder 4 is rotated relative to the internal threaded cylinder 3.2, so that the external threaded cylinder 4 gradually moves upward, and finally lifts the circular blocking plate 2 upward to the highest point. At this time, the opening groove 4.1 is just completely located in the inner cavity of the air duct 1. Then swing the horizontal tube body 5.1 relative to the external threaded cylinder 4, so that the opening direction of the air outlet hood 5.3 is opposite to the set position. At this time, the cold air generated by the refrigerator is first discharged into the air duct 1, and then flows through the opening groove 4.1, the inner cavity of the external threaded cylinder 4, the inner cavity of the sleeve 5.2, and the inner cavity of the horizontal tube body 5.1 in turn, and finally discharged downward from the opening of the air outlet hood 5.3.

[0033] The bottom surface of the circular plugging plate 2 is provided with a sealing ring, so that when the circular plugging plate 2 is sealed on the circular hole 1.1, the circular hole 1.1 can be airtightly sealed; at the same time, the guide column 2.1 is located at the lowest position, and the top surface of the horizontal support plate 3.1 must be lower than the lowest position. A flexible sealing ring is arranged inside the circular hole 1.1, so that when the external threaded cylinder 4 is inserted into the circular hole 1.1, an airtight structure is formed between the two to reduce air leakage.

[0034] In order to facilitate the rotation of the externally threaded cylinder 4, a handle 4.2 is fixedly connected to the middle of the outer peripheral wall of the externally threaded cylinder 4 along its radial direction.

[0035] In order to facilitate the positioning of the swing air outlet mechanism 5, a threaded sleeve 5.4 is fixedly mounted on the side wall of the sleeve 5.2 near the top in the radial direction, and a positioning bolt 5.5 is mounted on the inner thread of the threaded sleeve 5.4. That is, when the positioning bolt 5.5 is tightened, the inner end of the positioning bolt 5.5 will be pressed against the outer peripheral wall at the bottom of the external thread cylinder 4, so that the swing air outlet mechanism 5 and the external thread cylinder 4 are relatively fixed.
