Description

Technical Field

[0001] The utility model relates to the field of heating, ventilation and air conditioning, and in particular to an air volume regulating mechanism for heating, ventilation and air conditioning. Background Art

[0002] HVAC is an air conditioner with heating, ventilation and air conditioning functions. The HVAC system can control the temperature and humidity of the air and improve indoor comfort. It is an important part of medium and large industrial buildings or office buildings. It is used to adjust the air flow and pressure. The air volume adjustment mechanism is usually installed in the air duct, allowing the air flow to be adjusted to suit the system needs. HVAC is an important part of buildings such as hospitals or schools.

[0003] However, most of the air volume adjustment mechanisms used in HVAC currently have the following problems:

[0004] For example, the air volume adjustment device for HVAC with publication number CN220931336U can adjust the use of the wind screen by tightening the adjusting nut, but when fixing the wind screen, it is necessary to tighten the adjusting nut multiple times to fix it. Adjustment requires tightening or loosening the adjusting nut, which is troublesome to use and inconvenient to adjust the use of the wind screen conveniently. At the same time, in order to ensure clean air is blown out, most existing HVAC equipment installs filter plates for filtering. In order to improve the filtering stability, most of them are connected and fixed with bolts to avoid the filter plates from falling off. After long-term use, impurities clog the filter plates, which easily affects the filtering effect, making it inconvenient to disassemble and clean the filter plates conveniently.

[0005] Therefore, we make improvements to this and propose an air volume adjustment mechanism for HVAC. Utility Model Content

[0006] The purpose of the utility model is to solve the existing problems of inconvenience in conveniently adjusting and limiting the use of the windshield curtain and inconvenience in conveniently disassembling and cleaning the filter plate.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] An air volume regulating mechanism for heating, ventilation and air conditioning is used to improve the above problems.

[0009] The specific application is as follows:

[0010] The cam is fixedly provided with a first end in contact with the first link, and the second end in contact with the first link is fixedly provided with a first spring, and the cam is fixedly provided with a first spring, and the cam is fixedly provided with a second link.

[0011] As a preferred technical solution of the present application, the cross-sections of the guide block and the slider are both "T"-shaped, and the side end surface of the limit plate is in contact with the inner side surface of the slider.

[0012] As a preferred technical solution of the present application, the sliders are symmetrically distributed on the left and right sides of the adjustment box, and the sliders correspond one-to-one with the pull rods through the limit plates.

[0013] As a preferred technical solution of the present application, the pull rod is fixedly connected to the center of one side of the limiting plate, and the inner side surface of the dustproof box is in contact with the outer side surface of the adjustment box.

[0014] As a preferred technical solution of the present application, the second springs are symmetrically distributed on the left and right sides of the installation box, and the second springs correspond one-to-one with the clamping blocks through the fixing plate.

[0015] As a preferred technical solution of the present application, a clamping block is fixedly connected to the fixed plate, an extrusion plate is fixedly connected to the fixed plate, and a cross section of one side of the clamping block is inclined.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. A slider is provided; when adjusting the position of the windshield to control the air volume, the traction ring can be pulled to drive the pull rod to move, and the pull rod can squeeze the first spring through the limit plate when moving. The upward movement of the pull rod can separate the Velcro from the Velcro on the adjustment box. When the slider is not hindered by the pull rod, the slider can be slid to drive the windshield on the second connecting rod to move. When moving, the second connecting rod can be supported by the guide block to move smoothly. Pull the windshield on the first connecting rod to move, extend the usable area of ​​the windshield, block the internal space of the adjustment box, and adjust the air volume. After the adjustment is completed, release the second connecting rod, and drive the limit plate and the pull rod to reset under the push of the first spring. The downward movement of the pull rod can fit the Velcro on the Velcro on the adjustment box, fix the pull rod and the slider, and you only need to pull the pull rod and slide the slider to adjust, thereby improving the adjustment efficiency.

[0019] 2. A card plate is provided; when disassembling the dustproof box, the extrusion plates on both sides of the installation box can be pushed to drive the fixed plate to move. The fixed plate can squeeze the second spring when moving, and at the same time the fixed plate can drive the card block to detach from the card plate. When the card plate on the dustproof box is unobstructed, the dustproof box on the adjustment box can be disassembled to clean the dust and impurities filtered by the dustproof box, thereby improving the disassembly and cleaning efficiency. When resetting the installation, insert the card plate on the dustproof box into the installation box, loosen the extrusion plates on both sides, and drive the fixed plate and the card block to reset under the push of the second spring. The card block can be smoothly engaged in the card plate for connection and fixation. BRIEF DESCRIPTION OF THE DRAWINGS
