Description

Technical Field

[0001] This utility model relates to the technical field of air cooler equipment, and in particular to an air cooler for cold storage. Background Technology

[0002] Evaporative air coolers are divided into industrial evaporative air coolers and household evaporative air coolers. Industrial evaporative air coolers are generally used in cold storage and cold chain logistics refrigeration environments. Household evaporative air coolers, also known as water-cooled air conditioners, are evaporative cooling and ventilation units that integrate cooling, ventilation, dust prevention, deodorization, and humidification.

[0003] Traditionally, large cold storage facilities use large air coolers for temperature control. These air coolers have multiple air vents with protective grilles. The outer edge of the protective grille has multiple sets of positioning holes along its circumference. By creating several sets of threaded holes on the air cooler's casing, the positioning holes are aligned with the threaded holes, and bolts are threaded through the positioning holes and threaded holes of the protective grille to fix its position on the air cooler. This prevents external objects from being sucked in and damaging the fan when it is running inside the air vent.

[0004] However, when cleaning the fan later, the personnel need to use appropriate tools to remove the bolts one by one when disassembling the protective grille. Some bolts are prone to stripping during disassembly after being used for a long time, which further increases the difficulty of disassembly and reduces the efficiency of disassembly. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cold air cooler for cold storage.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cold storage air cooler includes a body and an air outlet at its front end. An air guide tube is provided at the air outlet, and a protective grille is fitted on the air guide tube. The protective grille is composed of multiple sets of concentrically arranged grille rings and radial reinforcing ribs. The multiple sets of grille rings at the front end of the protective grille are arranged radially along the air guide tube, and the multiple sets of grille rings at the rear end have the same outer diameter and are arranged along the length of the air guide tube. The radial reinforcing ribs are connected to the outer wall of each set of grille rings. A positioning cylinder is provided on the air guide tube along its radial direction. A base plate is slidably arranged inside the positioning cylinder. A limit plate is rotatably arranged on the base plate through a rotating rod. An insertion rod is slidably arranged on the limit plate. An insertion hole is provided on the outer wall of the air guide tube to engage with the insertion rod.

[0007] Preferably, a telescopic spring is provided inside the positioning cylinder, and the bottom plate is connected to the inner wall of the positioning cylinder through the telescopic spring.

[0008] Preferably, a torsion spring is sleeved on the outside of the rotating rod, with one end of the torsion spring connected to the base plate and the other end connected to the limiting plate.

[0009] Preferably, an extension plate is provided at the end of the insertion rod away from the air guide tube, and a telescopic spring is provided on the extension plate and connected to the limiting plate. The limiting plate is provided with a limiting groove on the side facing the air guide tube that fits against the outer wall of the grille ring.

[0010] Preferably, the outer diameter of the positioning cylinder is smaller than the shortest distance between two adjacent sets of grid rings at the rear end of the protective grid, and the air guide duct is provided with a receiving groove for placing the limiting plate at the positioning cylinder.

[0011] Preferably, a friction pad is fitted on the outer wall of the insertion rod, and a flexible pad is provided on the side of the grid ring at the rear end of the protective grid facing the air guide tube.

[0012] The beneficial effects of this utility model are as follows: By setting a positioning cylinder on the air guide tube, a base plate is slidably set inside the positioning cylinder, and a limiting plate is rotatably set on the base plate via a rotating rod. The limiting plate is provided with an insertion rod, and an insertion hole is provided on the air guide tube for the insertion rod to be inserted. Compared with the prior art, this utility model allows the limiting plate to pass through the protective grille sleeved on the outside of the air guide tube, and the insertion rod is inserted into the insertion hole on the air guide tube. The rotating rod is positioned horizontally between two adjacent sets of grille rings in the protective grille, thereby limiting the protective grille to the outside of the air guide tube. At the same time, the limiting groove on the limiting plate fits against the outer wall of the grille ring in the protective grille, further enhancing the stability of the protective grille sleeved on the air guide tube during machine operation. When disassembling the protective grille, the insertion rod can be pulled out of the insertion hole, and the limiting plate can be moved a certain distance away from the air guide tube and then rotated a certain angle to allow the limiting plate to enter the receiving groove. This makes it convenient for personnel to install or remove the protective grille from the air guide tube without the need to find tools to install or remove the protective grille from the air guide tube.

[0021] The directional terms mentioned in this embodiment, such as "up," "down," "left," and "right," are merely used to help those skilled in the art understand the relationships between various features or parts in conjunction with the accompanying drawings.

[0022] In this embodiment, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 5As shown, a cold storage air cooler includes a body 1 and two sets of air outlets 2 at its front end. An air guide duct 3 is fixed at the air outlet 2. A protective grille 4 is fitted on the outer wall of the air guide duct 3. In this embodiment, the protective grille 4 is composed of multiple sets of concentrically arranged grille rings 401 and radial reinforcing ribs 402 that connect the sets of grille rings 401. The multiple sets of grille rings 401 at the front end of the protective grille 4 are arranged radially along the air guide duct 3, and the multiple sets of grille rings at the rear end have the same outer diameter and are arranged along the length of the air guide duct 3. The radial reinforcing ribs 402 are L-shaped and connect the outer walls of the sets of grille rings 401.

[0024] A positioning cylinder 5 is radially arranged on the outer wall of the air guide duct 3, and the positioning cylinder 5 is located between two adjacent sets of grid rings 401 at the rear end of the protective grid 4. A flexible pad 18 is provided on the inner wall of the grid rings 401 at the rear end of the protective grid 4. Figure 3 As shown, a telescopic spring 11 is installed inside the positioning ring. The right end of the telescopic spring 11 is connected to the base plate 6. A rotating rod 7 is rotatably connected to the right side of the base plate 6. A limiting plate 8 is fixedly connected to the right side of the rotating rod 7. A torsion spring 12 is sleeved on the outside of the rotating rod 7. One end of the torsion spring 12 is connected to the base plate 6, and the other end is connected to the limiting plate 8. The length of the limiting plate 8 is greater than the shortest distance between two adjacent sets of grid rings 401 at the rear end of the protective grid 4. The purpose of this is to limit the movement of the protective grid 4 through the limiting plate 8. The limiting plate 8 has a rod 9 on the side facing the air duct 3. A friction pad 16 is fitted on the outer wall of the rod 9. The rod 9 is slidably connected to the limiting plate 8. An insertion hole 10 is opened on the outer wall of the air duct 3 to engage with the rod 9. An extension plate 13 is connected to the end of the rod 9 away from the air duct 3. A second telescopic spring 14 is provided on the extension plate 13 and connected to the outer wall of the limiting plate 8. The second telescopic spring 14 is fitted on the outside of the rod 9. A limiting groove 15 is provided on the side of the limiting plate 8 facing the air duct 3 to fit against the outer wall of the grille ring 401.

[0025] The outer diameter of the positioning cylinder 5 is smaller than the shortest distance between the two adjacent sets of grid rings 401 at the rear end of the protective grid 4. The air guide duct 3 has a receiving groove 17 for placing the limiting plate 8 at the positioning cylinder 5 to avoid interference caused by the limiting plate 8 when the protective grid 4 is removed or installed. It should be noted that in this embodiment, when the limiting plate 8 is parallel to the grid ring 401, a notch is opened on the side facing the air guide duct 3 opposite to the outer wall of the positioning cylinder 5 (not shown in the attached figure). The purpose is that when the limiting plate 8 enters the receiving groove 17, the positioning cylinder 5 will extend into the notch to avoid interference with the movement of the limiting plate 8.

[0026] When the protective grille 4 is installed on the air duct 3 of the air cooler body 1, the limiting plate 8 is located at the end of the grille ring 401 at the rear end of the protective grille 4 away from the air duct 3. The torsion spring 12 is in a torsional state. The limiting groove 15 on the limiting plate 8 fits against the outer wall of the grille ring 401. At the same time, the insertion rod 9 on the limiting plate 8 is inserted into the insertion hole 10 on the outer wall of the air duct 3. The second telescopic spring 14 is in the initial state. The first telescopic spring 11 located in the positioning cylinder 5 is also in the initial state. When the limiting plate 8 is pulled towards the air duct 3, the flexible pad 18 is in a compressed state. At this time, the entire protective grille 4 is limited at the air duct 3 of the body 1, which plays a protective role.

[0027] To remove the protective grille 4 from the air duct 3, first pull the extension plate 13 to pull the insertion rod 9 away from the insertion hole 10. Then, hold the limiting plate 8 and pull it away from the air duct 3 to stretch the telescopic spring 11. Ensure that the grille ring 401 at the rear end of the protective grille 4 does not interfere. Then, release the force on the limiting plate 8, and the torsion spring 12 will start to reset, pulling the limiting plate 8 to rotate 90 degrees so that the limiting plate 8 is parallel to the grille ring 401 at the rear end of the protective grille 4. After that, stop pulling the limiting plate 8, and the telescopic spring 11 will retract at the same time, pulling the limiting plate 8 into the receiving groove 17. Perform the same operation on each group of positioning cylinders 5 on the air duct 3. After all are completed, the protective grille 4 can be removed. This is convenient and quick, and there is no need to find tools for disassembly and installation.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
