AI Technical Summary
In the traditional pressure-regulating side blower, when the cold air enters the bellows, the wind speed is affected by resistance, resulting in slower wind speed and uneven air volume.
An air duct adjustment plate is designed, including a bellows, an inclined plate, a first adjustment plate and a second adjustment plate. By adjusting the positions of the first adjustment plate and the second adjustment plate, the upper end of the first adjustment plate is lower than the upper end of the second adjustment plate, thereby accelerating the wind speed and ensuring that the air volume is uniform when the cold wind blows through these plates.
By adjusting the position of the adjustment plate, the wind speed at the bellows wall can be significantly accelerated, thereby ensuring that the air volume is uniform when the cold air blows through these plates, solving the problem of uneven air volume.

Technical Field
[0001] The utility model relates to the field of regulating plates, in particular to an air duct regulating plate. Background Art
[0002] In the traditional pressure-stabilizing side-blowing bellows, the cold air sent by the air supply fan enters from the cold air inlet. When the cold air enters the bellows from the air inlet, the wind speed on both sides close to the bellows wall is affected by resistance and the wind speed is slower, so the wind is not uniform. By adjusting the four air duct adjustment plates, it is ensured that the air volume can be kept uniform on the left and right before the cold air enters the three-layer bellows device. Utility Model Content
[0003] The utility model aims to provide an air duct adjustment plate to solve the problems raised in the above-mentioned background technology, which has the advantage of keeping the air volume uniform on the left and right.

[0005] By adopting the above technical solution, the wind speed near the bellows wall is affected by resistance and is slow. It is necessary to lower the first adjustment plates on both sides so that the upper end of the first adjustment plate is lower than the upper end of the second adjustment plate. At this time, the wind speed at the bellows wall can be accelerated so that the cold air can be evenly distributed when blowing over the first adjustment plate and the second adjustment plate.
[0006] As a further solution of the utility model: the inclined plate includes a first positioning plate that is inclined relative to the opening direction of the air inlet, and a second positioning plate is integrally connected to one side of the first positioning plate.
[0007] By adopting the above technical solution, the first positioning plate is tilted to facilitate guiding the flow direction of the cold air.
[0008] As a further solution of the utility model: the second positioning plate is provided with a threaded hole passing through the second positioning plate, the first adjustment plate and the second adjustment plate are both provided with a long groove passing through the first adjustment plate and the second adjustment plate, the second positioning plate is fixedly connected to the first adjustment plate and the second adjustment plate by bolts passing through the threaded hole and the long groove, and the bolts are threadedly connected with nuts.
[0009] By adopting the above technical solution, after adjusting the first adjustment plate and the second adjustment plate to the appropriate position, the bolts are passed through the threaded holes and the long grooves in sequence, and then the nuts are rotated to make the first adjustment plate and the second adjustment plate and the second positioning plate in a relatively fixed state.
[0010] As a further solution of the utility model: a reinforcing rod is integrally connected to the inner side of the second positioning plate, and reinforcing plates are integrally connected to both ends of the reinforcing rod.
[0011] By adopting the above technical solution, the provision of the reinforcing rod and the reinforcing plate increases the strength of the second positioning plate.
[0012] As a further solution of the present invention: the first adjustment plate and the second adjustment plate are both integrally connected with an L-shaped plate extending inward.
[0013] By adopting the above technical solution, the setting of the L-shaped plate plays a certain guiding role.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] Near the bellows wall, the wind speed is affected by resistance and is slow. It is necessary to lower the first adjustment plates on both sides so that the upper end of the first adjustment plate is lower than the upper end of the second adjustment plate. At this time, the wind speed at the bellows wall can be accelerated so that the cold air can be evenly distributed when blowing over the first adjustment plate and the second adjustment plate.
