AI Technical Summary
The structural stability of the existing clean room air volume hood auxiliary frame is poor, which can easily lead to the drop of the air volume hood, especially when the ventilation opening is not parallel to the ground, the detection result is distorted.
The height adjustment mechanism including a lifting structure is adopted, which consists of a fixed block, a rotating rod, a bevel gear, a screw rod and a support plate. By manually operating the active bevel gear, the driven bevel gear and the screw rod are driven to realize the lifting and lowering movement of the air volume cover. Make sure it is closely aligned with the vents.
It improves the stability and use value of the air volume hood, so that accurate detection results can be maintained when the vent is not parallel to the ground and avoid falling.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary frames, in particular to a height adjustment structure of an auxiliary equipment frame of a clean room air volume hood. Background Art
[0002] The air volume hood is mainly composed of three parts: the air volume hood body, the base, and the PDA. The air volume hood body is mainly used to collect air volume and collect the wind to the wind speed uniformizer on the base. A wind pressure sensor is installed on the wind speed uniform base. The sensor reflects the change of wind speed and then calculates the air volume according to the size of the base. The air volume hood is displayed using a PDA. The large-screen LCD screen is intuitive and can directly obtain the data of wind speed, wind temperature and air volume. The recording time interval can be set for continuous parameter recording in order to analyze the data. The measured and recorded data is recorded on the memory card and will not be lost. The data can be transferred to the PC through the computer's serial port for further application.
[0003] Chinese patent CN212228147U discloses an auxiliary frame for clean room air volume hood, which aims to solve the problem that when measuring air volume, if the vent is not level with the ground, a gap will appear at the place where the upper end of the air volume hood placed on the auxiliary frame abuts against the vent, causing the gas discharged from the vent to escape from the gap, so that the result of the air volume hood detection is distorted. The key points of its technical solution are as follows: it includes a base, a lifting rod and a support frame, and a plurality of fixing devices and limit grooves for fixing the lower end of the air volume hood are installed on the support frame. A support block is placed in the limit groove, and the lower end of the air volume hood is placed on the support block. An adjustment mechanism is connected to the lower part of the support block. The height of the support block is adjusted by the adjustment mechanism, thereby driving the horizontal height of the air volume hood in this direction. The adjustment mechanisms in the plurality of limit grooves are adjusted together to change the direction of the upper end of the air volume hood. Even if the vent is not parallel to the ground, the upper end of the air volume hood can be aligned with the vent and tightly abutted against the vent, so that the detection result remains accurate. The structural stability is poor, which can easily cause the air volume hood to fall off.
[0004] Therefore, in order to solve such problems, we propose a height adjustment structure for an auxiliary equipment rack of a clean room air volume hood. Utility Model Content
