Novel air door of air conditioning unit for rail vehicle

Abstract

The invention discloses a novel air door of an air conditioning unit for a rail vehicle. The novel air door comprises a housing assembly, an adjusting assembly and a connecting assembly, wherein the housing assembly comprises a housing body, fixing nuts, built-in shafts, blades, a connecting pipe and a spacer plate, wherein the fixing nuts are positioned on the upper surface of the housing body and are fixedly connected with the housing body; the inner side wall of the housing body is rotatably connected with the built-in shafts; the blades are positioned on the outer side walls of the built-in shafts and are fixedly connected with the built-in shafts; the connecting pipe is arranged at the middle positions of the blades; the blades are rotatably connected with the connecting pipe. The novel air door of the air conditioning unit for the rail vehicle is provided with the blades, the connecting pipe and connecting ends, and the blades can be spliced and rotated, so that the transmitted air volume can be changed, and real-time using is realized; transmission control can be performed on the air door by means of a supporting box, an adjusting disc and a connecting arm, so that novel airdoor is convenient to disassemble when being cleaned, and the effects of changing the transmitted air volume and facilitating operation are achieved.

Description

technical field [0001] The invention belongs to the technical field of novel dampers, and in particular relates to a novel damper for rail vehicle air-conditioning units. Background technique [0002] The central air conditioner has two air supply systems, one is to absorb fresh air from the outside, called fresh air, the switch of this road is the fresh air door, and the other is to circulate the return air from the system, called return air. [0003] When the damper of the original rail vehicle air-conditioning unit is in use, it is placed in a fixed area, so that the air intake volume of the air conditioner cannot be changed. In addition, during long-term use, it is extremely inconvenient to disassemble and clean the internal shaft, and it is impossible to change the transmission air volume and Easy to operate effect. Contents of the invention [0004] The object of the present invention is to provide a new damper for rail vehicle air conditioners to solve the problem ...
