Description

Technical Field

[0001] This utility model relates to the field of air guide structure technology, specifically an air guide structure for a cold storage. Background Technology

[0002] Cold storage is used for the freezing and refrigeration of food, medicine, and machinery. It maintains a certain low temperature indoors through artificial refrigeration. However, storage or manufacturing requires not only low temperature, but also air exchange with the outside environment. Therefore, cold storage is equipped with a ventilation system.

[0003] In existing technologies, the ducts of cold air systems are fixed. However, when the quantity, height, and placement of items in the cold storage change, the direction of the air ducts needs to be adjusted. The direction of existing air ducts is mostly unadjustable or has a small adjustment range. When the shelves are high, they are easily blocked, which makes it impossible to ensure the uniformity of temperature in the cold storage. In view of this, we propose an air guiding structure for cold storage. Utility Model Content

Air inlets extending into the interior are opened on the adjacent surfaces of the two air inlet pipes. Two fixing plates are fixedly connected to the front and rear surfaces of the horizontal plates of the U-shaped ventilation duct, and a limit rod is fixedly connected between the two adjacent fixing plates. Fixed air outlet pipes are fixedly connected to the front and rear surfaces of the U-shaped ventilation duct, and the fixed air outlet pipes communicate with the interior of the U-shaped ventilation duct. An mounting plate is slidably fitted onto the outer surface of the limit rod. Movable air outlet pipes are fixedly connected to the opposite surfaces of the two mounting plates. A folding pipe is provided between the movable air outlet pipe and the fixed air outlet pipe, and the folding pipe communicates with the interior of both the movable and fixed air outlet pipes. An adjustment component is provided on the U-shaped ventilation duct.

[0006] Preferably, the adjustment assembly includes a drive box, which is fixedly connected to the lower surface of the U-shaped ventilation duct, and the drive box has two cavities inside.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figures 1-4 As shown, a cold storage ventilation structure includes a U-shaped ventilation duct 1. Air inlet pipes 2 are fixedly connected to the adjacent surfaces of the two vertical plates of the U-shaped ventilation duct 1. A fan is installed inside each air inlet pipe 2. Air inlets 3 extending into the interior of each adjacent surface of the two air inlet pipes 2 are provided. Two fixing plates 4 are fixedly connected to the front and rear surfaces of the horizontal plates of the U-shaped ventilation duct 1. Limiting rods 5 are fixedly connected between two adjacent fixing plates 4. Fixed outlet pipes 6 are fixedly connected to the front and rear surfaces of the U-shaped ventilation duct 1. The fixed outlet pipes 6 are connected to the interior of the U-shaped ventilation duct 1. The components are connected, and the outer surface of the limiting rod 5 is slidably fitted with the mounting plate 7. The opposite sides of the front and rear mounting plates 7 are fixedly connected with the movable air outlet pipe 8. A folding pipe 9 is provided between the movable air outlet pipe 8 and the fixed air outlet pipe 6. The folding pipe 9 is connected to the interior of the movable air outlet pipe 8 and the fixed air outlet pipe 6. An adjustment component is provided on the U-shaped ventilation pipe 1. The movable component drives the movable air outlet pipe 8 to move, thereby adjusting the position of the air outlet channel over a wide range, avoiding the high shelf from obstructing the air flow. At the same time, the folding pipe 9 provides a certain amount of movement space while ensuring continuous connection.

[0022] Furthermore, the adjustment assembly includes a drive box 10, which is fixedly connected to the lower surface of the U-shaped ventilation pipe 1. The drive box 10 has two cavities 11 inside, and each cavity 11 has a forward and reverse motor 12 fixedly connected to its inner wall. The two forward and reverse motors 12 are mirror images of each other. The output ends of each of the two forward and reverse motors 12 are fixedly connected to threaded rods 13 via couplings. The opposite ends of the two threaded rods 13 rotatably extend out of the drive box 10 and are rotatably connected to the vertical plate of the U-shaped ventilation pipe 1. Connecting plates 14 are fixedly connected to the lower surfaces of two adjacent mounting plates 7. The lower surfaces of the connecting plates 14... A threaded sleeve 15 is fixedly connected to the surface of the threaded rod 13. The threaded sleeve 15 is threaded onto the outer surface of the threaded rod 13. An embedded groove 16 is provided on the upper surface of the air inlet pipe 2. A through groove 17 extending into the interior of the air inlet pipe 2 is provided on the bottom wall of the embedded groove 16. An installation frame 18 is provided inside the air inlet pipe 2. A filter plate 19 is fixedly connected to the inner wall of the installation frame 18. The upper surface of the installation frame 18 extends out of the upper surface of the air inlet pipe 2 through the through groove 17. A lifting handle 20 is fixedly connected to the upper surface of the installation frame 18. By using the filter plate 19, it is possible to prevent dust from the ground from being transported to the upper side and discharged when cold air is drawn in from the bottom, thus preventing the goods from being covered by dust.

[0023] The forward and reverse motor 12 mentioned in the article is an existing structure, and will not be described in detail here.

[0024] Working principle: Cold air from the bottom of the cold storage is drawn into the air inlet duct 2 by a fan. After being filtered by the filter plate 19, the cold air enters the U-shaped ventilation duct 1, then the fixed air outlet duct 6, and finally the movable air outlet ducts 8 on both sides through the folded pipe 9. The air is then discharged from the top of the cold storage, thus balancing the temperature difference between the bottom and top of the cold storage. When the shelves at the bottom of the movable air outlet duct 8 are high, or when the cold air cannot blow directly onto them, the forward and reverse motors 12 can drive the threaded rod 13 to rotate. The threaded sleeve 15's movement trajectory is restricted by the connecting plate 14, which in turn is limited by the two mounting plates 7. Position rod 5 restricts the movement trajectory, so when threaded rod 13 rotates, it will synchronously drive threaded sleeve 15 to move horizontally. In turn, the movement of threaded sleeve 15 will drive connecting plate 14 and mounting plate 7 to move. When mounting plate 7 moves, it will drive moving air outlet pipe 8 to move horizontally. When moving air outlet pipe 8 moves, it will provide movement space with the folding feature of folding pipe 9 without breaking the connection with fixed air outlet pipe 6, thereby achieving the purpose of adjusting the position of air outlet channel over a wide range. When filter plate 19 is dirty, it can be pulled out and replaced by lifting handle 20. At the same time, during installation, sealing gaskets can be added and fixed bolts can be tightened to prevent air leakage.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
