Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically to a wind speed regulating mechanism for building ventilation. Background Technology

[0002] Ventilation system refers to the general term for ventilation methods and ventilation networks. Ventilation methods are divided into central, diagonal, zoned and mixed types. Ventilation method refers to the working method of the main ventilation fan supplying air to the building. The existing technology has a fixed wind speed in the ventilation network, which cannot be adjusted according to actual needs in actual use, resulting in poor practicality. Therefore, we propose a wind speed adjustment mechanism for building ventilation. Utility Model Content

[0003] The purpose of this utility model is to provide a wind speed regulating mechanism for building ventilation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind speed regulating mechanism for building ventilation, comprising a ventilation duct, wherein an exhaust pipe is fixedly connected to the left end of the ventilation duct, an air inlet pipe is fixedly connected to the right end of the ventilation duct, and an opening is provided on the right side of the top of the ventilation duct, wherein a liftable baffle is movably arranged inside the opening.

[0005] Furthermore, the top and bottom of the baffle extend to the outside of the opening, and a telescopic rod is fixedly connected to the top right side of the ventilation duct, with a fixed plate fixedly connected to the telescopic end of the telescopic rod.

[0006] Furthermore, the bottom of the fixing plate is fixedly connected to the top of the baffle, the baffle is movably connected to the ventilation duct, and a vertical plate is fixedly connected to the top of the ventilation duct and to the left of the fixing plate.

[0007] Furthermore, multiple fixing slots are sequentially provided on the right side of the vertical plate from bottom to top, and a horizontally movable locking block is movably engaged inside the uppermost fixing slot.

[0008] Furthermore, the right side of the snap-fit ​​block extends to the outside of the fixed slot, and a movable slot is provided on the top of the fixed plate. The left and right sides of the inner wall of the movable slot are fixedly connected by a sliding column.

[0009] Furthermore, a movable block is slidably connected to the left side of the sliding column surface, the movable block is movably connected to the moving groove, and both the front and rear sides of the movable block are in contact with the inner wall of the moving groove.

[0010] Furthermore, the top of the movable block extends to the outside of the moving groove, the left side of the movable block is fixedly connected to the right side of the snap-fit ​​block, a pull ring is fixedly connected to the top right side of the movable block, and a spring is sleeved on the surface of the sliding column and located on the right side of the movable block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the wind speed in the ventilation duct needs to be adjusted, this utility model only requires pulling the pull ring to the right to move the movable block and the locking block to the right, thereby compressing the spring and causing the locking block to disengage from the fixed slot. Then, pulling the fixed plate downward will move the baffle downward, allowing it to descend to the appropriate position. Releasing the pull ring will cause the locking block to reset under the spring force, allowing it to insert into the fixed slot at the corresponding height. Through these steps, the ventilation area of ​​the air inlet duct can be changed by altering the relative position of the baffle and the air inlet duct, thus achieving the adjustment of the wind speed in the ventilation duct.
