An arc-shaped groove is opened on one side of the adjusting disc, and a locking component is installed in the arc-shaped groove to fix the position of the adjusting disc after adjustment.

[0007] Specifically, the locking component includes a stud disposed in an arc-shaped groove, an adjusting disc that rotates freely around the arc-shaped groove, a threaded connection between the lower side of the stud and the mounting plate, a circular washer fitted on the upper side of the stud, the circular washer being located on the upper side of the adjusting disc, a locking cap being installed on the upper side of the circular washer, and the locking cap being fixedly connected to the stud.

[0008] Specifically, the sealing component includes a rubber outer cylinder fitted onto the connection between the ventilation pipe and the outer pipe. The upper side of the rubber outer cylinder has a groove, and two arc-shaped pressure rings with their bottoms intersecting are connected in contact within the groove. Each arc-shaped pressure ring has a binding plate with a vertical groove fixedly installed on its upper side. A locking screw is rotatably connected inside one binding plate, and the locking screw freely enters the other binding plate and is threadedly connected to a locking cap.

[0009] Specifically, the ventilation box is symmetrically threaded with lifting rings, and a right-angled triangular bracket is symmetrically fixed on the side of the ventilation box facing the main pipe, with multiple mounting holes on the right-angled triangular bracket.

[0010] Specifically, an adjustment handle is fixedly installed on the side of the adjustment disc away from the arc-shaped groove.

[0011] Specifically, the adjustment disc has a scale value on one side of the arc-shaped groove.

[0012] Compared with the prior art, the ventilation equipment of this utility model that facilitates connection to ventilation ducts has at least the following beneficial effects:

[0013] This invention utilizes the combination of an adjusting disc and a square column to rotate the valve plate, thus altering the airflow velocity within the ventilation duct. The combination of a stud, a circular washer, and the adjusting disc facilitates fixing the adjusting disc's position on the mounting plate, thereby fixing the valve plate's angular position within the ventilation duct.

Therefore, they should not be construed as limitations on this utility model.

[0022] This embodiment discloses a ventilation device that is easy to connect to ventilation ducts, such as... Figure 1-5 As shown, the device includes a ventilation box 1, a main pipe 3 fixedly connected to the side of the ventilation box 1, and ventilation connecting pipes 5 symmetrically fixedly connected to the main pipe 3 along its length. An airflow regulating component is fixedly installed inside the ventilation connecting pipe 5 to adjust the airflow on the side of the ventilation connecting pipe 5 away from the main pipe 3. An outer pipe 6 is threadedly connected to the end of the ventilation connecting pipe 5 away from the main pipe 3. A sealing component is installed on the outside of the connection between the ventilation connecting pipe 5 and the outer pipe 6 to seal the gap at the connection between the ventilation connecting pipe 5 and the outer pipe 6.

[0023] The airflow regulating component includes a rotating shaft that is rotatably and sealed within the ventilation pipe 5. A valve plate 15 is fixedly connected to the rotating shaft and is located inside the ventilation pipe 5. The upper side of the rotating shaft extends to the upper side of the ventilation pipe 5 and is fixedly connected to a square column 8. A slotted mounting plate 4 is fixedly installed on the upper side of the ventilation pipe 5. An adjusting disc 9 is inserted into the upper side of the square column 8. An arc-shaped groove 11 is opened on one side of the adjusting disc 9. A locking component is installed in the arc-shaped groove 11 to fix the position of the adjusting disc 9 after adjustment. By rotating the adjusting disc 9, the adjusting disc 9 drives the square column 8 to rotate, and the square column 8 drives the valve plate 15 to rotate, thereby changing the airflow velocity inside the ventilation pipe 5.

[0024] The locking component includes a stud disposed in an arc-shaped groove 11. The adjusting disc 9 rotates freely around the arc-shaped groove 11. The lower side of the stud is threaded to the mounting plate 4. A circular washer 12 is fitted on the upper side of the stud. The circular washer 12 is located on the upper side of the adjusting disc 9. A locking cap 10 is installed on the upper side of the circular washer 12. The locking cap 10 is fixedly connected to the stud. After the adjusting disc 9 is rotated to a suitable angle, the locking cap 10 is rotated. The locking cap 10 drives the circular washer 12 to move towards the adjusting disc 9, thereby fixing the position of the adjusting disc 9 on the mounting plate 4, and thus fixing the angular position of the valve plate 15 within the ventilation pipe 5.

[0025] The sealing component includes a rubber outer cylinder 18 fitted at the connection between the ventilation pipe 5 and the outer pipe 6. The upper side of the rubber outer cylinder 18 has a groove, within which two arc-shaped pressure rings 14, whose bottoms meet, are in contact. Each arc-shaped pressure ring 14 has a binding plate 16 with a vertical groove fixedly installed on its upper side. A locking screw 17 is rotatably connected to one binding plate 16, and the locking screw 17 freely enters the other binding plate 16 and is threadedly connected to a locking cap 13. The outer diameter of the locking cap 13 is larger than the width of the vertical groove. By rotating the locking cap 13, the upper sides of the two arc-shaped pressure rings 14 move closer together, thereby fixing the rubber outer cylinder 18 at the gap between the ventilation pipe 5 and the outer pipe 6 through the arc-shaped pressure rings 14, thus achieving a sealing effect and reducing the corrosion of the connection between the ventilation pipe 5 and the outer pipe 6 by external water.

[0026] The ventilation box 1 is symmetrically threaded with lifting rings 2, which facilitates moving the device to a suitable position. A right-angled triangular bracket 19 is symmetrically fixed on the side of the ventilation box 1 facing the main pipe 3. The right-angled triangular bracket 19 has multiple mounting holes. The device is fixed to the workbench by using locking screws through the mounting holes of the right-angled triangular bracket 19.

[0027] An adjustment handle 7 is fixedly provided on the side of the adjustment disc 9 away from the arc groove 11, and the angle of the adjustment disc 9 can be easily adjusted by adjusting the handle 7.

[0028] The adjustment disc 9 has a scale value on one side of the arc groove 11, which makes it easy for the staff to accurately adjust the angle of the valve plate 15 at the ventilation pipe 5.

[0029] In use, the outer pipe 6 is installed into one end of the ventilation pipe 5. The gap at the connection between the ventilation pipe 5 and the outer pipe 6 is sealed by the sealing component. According to the output air volume in the two ventilation pipes 5, the air volume entering the outer pipe 6 is adjusted by adjusting the air volume regulating component. After rotating the adjusting plate 9 to a suitable angle, the locking cap 10 is rotated. The locking cap 10 drives the circular pad 12 to move towards the adjusting plate 9, thereby fixing the position of the adjusting plate 9 on the mounting plate 4, and thus fixing the angular position of the valve plate 15 in the ventilation pipe 5.
