Description

Technical Field

[0001] The present application relates to the technical field of air duct hangers, and more specifically, to an air duct hanger for a building central air conditioner. Background Art

[0002] The construction of high-rise buildings requires the installation of large central air-conditioning equipment so that each floor of the building can achieve the cooling effect of central air-conditioning. The air duct of the central air-conditioning is composed of air ducts. When the air ducts are installed along the floors, they need to be suspended and installed on the roof of each floor of the building using a hanger. The traditional hanger includes hanging wires, expansion bolts and supporting steel. The structure is simple and the construction is convenient. However, after installation, it does not have the purpose of shock absorption and buffering of the air duct and silent and wear-resistant installation. The existing public technology number CN218178099U proposes a central air-conditioning air duct hanger. The device can be installed without disassembling the hanging chain. By directly disassembling the hanger, the suspension state of the hanger can be quickly released, or the hanging state of the hanger can be quickly formed. The disassembly and assembly are simple, fast and convenient, which improves the efficiency of air duct diversion, cleaning, maintenance or replacement. Regarding the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: after installation, the hanger in the comparative literature is difficult to clamp and limit air ducts of different models, and the air duct still does not have the purpose of shock absorption and buffering and silent and wear-resistant installation after installation. In addition, the thermal insulation cotton wrapped around the outside of the air duct is easily worn, resulting in a decrease in the air conditioning cooling effect. In view of this, we propose a building central air conditioning duct hanger. Utility Model Content

The application realizes a rectangular frame structure connected by two clamping beams and two buffers, and the installation height of the buffer can be adjusted by loosening the lock nut to make the screw slide along the strip groove. The distance between the two buffers can be adjusted by rotating the adjusting threaded rod, and then different types of air ducts can be clamped.
