[0022] 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.

[0023] This specific implementation method is a metal air duct that is easy to maintain, and its structural schematic diagram is as follows Figure 1 , Figure 2 As shown, it includes a duct body 3, a shielding plate 2, and a locking assembly 1. A maintenance port 6 is provided on the side wall of the duct body 3. A side cover 5 adapted to shield the maintenance port 6 is provided. The shielding plate 2 is connected to the side cover 5. The connection between the shielding plate 2 and the side plate is stepped. The shielding plate 2 covers the side cover 5. The locking assembly 1 is fixedly installed on the outer wall of the duct body 3, and the locking assembly 1 is adapted to connect with the shielding plate 2.

[0024] Reference Figure 3 The locking assembly 1 includes a limit rod 7, a fixed rod 12, a fixed column 8 and a series plate 13. The limit rod 7 is in a U-shaped structure and is inserted into the fixed rod 12 and slides toward the shielding plate 2. A limit hole 4 is provided on the side wall of the shielding plate 2. The fixed rod 12 is adapted to be plugged in with the limit rod 7, and a handle 9 is provided on the limit rod 7. There are two groups of fixed rods 12 distributed horizontally at intervals. The two groups of fixed rods 12 are fixed by a series plate 13, and the series plate 13 is fixedly connected to the outer wall of the air duct body 3. The interior of the fixed rod 12 is hollow, and movable grooves 11 are respectively provided on the facing surfaces of the two groups of fixed rods 12. The limit rod 7 passes through the movable groove 11 and extends into the fixed rod 12 for sliding installation, and a fixed column 8 is fixedly installed at the end of the limit rod 7.

[0025] Reference Figure 3 , Figure 4The fixed column 8 is arranged horizontally, and a fixed head 14 is fixed to the end away from the end connected to the limit plug rod 7. A spring 15 is connected to the fixed head 14, and the spring 15 is fixed to the inner wall of the fixed rod 12. A shielding bar 10 is also fixedly connected to the outer wall of the limit plug rod 7, and the shielding bar 10 fits the lower edge of the moving groove 11 and slides.

[0026] Working principle: When in use, first connect the air duct body 3 with the straight pipe. When the inside of the air duct body 3 needs maintenance and repair, the locking assembly 1 can be operated to separate the side cover 5, and the handle 9 can be pulled. The handle 9 drives the limiting plug rod 7 to slide along the moving groove 11, and then the end of the limiting plug rod 7 is separated from the inside of the limiting plug hole 4. After losing the limiting force, the shielding plate 2 can be disassembled, and then the maintenance port 6 is exposed, and the inside of the air duct body 3 can be maintained and repaired. After cleaning out the impurities, the side cover 5 is engaged with the maintenance port 6 again, and the shielding plate 2 is fixed by the locking assembly 1. The shielding plate 2 and the side cover 5 are arranged in a step shape, and the side cover 5 fits with the maintenance port 6. The shielding plate 2 fits the surface of the air duct body 3, and the contact position between the shielding plate 2 and the air duct body 3 has a sealing strip;

[0027] When the limiting rod 7 leaves the shielding plate 2, the fixed column 8 slides along the movable groove 11, and the spring 15 is compressed by the force. When the fixed column 8 moves, the shielding strip 10 moves synchronously to block the movable groove 11. In other words, when the limiting rod 7 and the shielding plate 2 are in a plug-in and fixed state, the shielding strip 10 serves to shield and seal the movable groove 11 to prevent dust from entering the interior and affecting the service life of the metal components. When the limiting rod 7 is in a clamping state, the elastic force of the spring 15 supports the fixed column 8, so that the limiting rod 7 is pressed tightly inside the shielding plate 2.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
