Manually adjustable supply air outlets for rail vehicle air conditioning

Abstract

The invention discloses a manual adjustable air supply outlet used for a railway vehicle air conditioner, which comprises a driving rotary piece, a first driven rotary piece, a second driven rotary piece, a connecting rod, a clamping piece, a ferrule and a base, wherein the driving rotary piece is an oval structural member; the first driven rotary piece and the second driven rotary piece are circular arc structural members; the connecting rod is a long strip structural member with a slot in the middle; the clamping piece is a structural member with an arc outer part; an upper edge of the ferrule is protruded; an arc bayonet and a clamp connecting structure in a corresponding position are arranged on the wall of the ferrule; the upper edge of the base is protruded, and a circular ring structure is arranged on the inner wall of the base; the driving rotary piece, the first driven rotary piece and the second driven rotary piece are movably connected via the connecting rod and are then connected onto the ferrule in an embedded manner via a positioning bulge, and are finally fixed and positioned via the clamping piece; then the ferrule is movably clamped onto the base, so that the ferrule can rotate on the base. The manual adjustable air supply outlet has the advantages as follows: blast capability and blowing direction of the air vent of the railway vehicle air conditioner can be adjusted in all directions, independent adjustment of blast capability and blowing direction in the horizontal plane can be realized, and manufacture and use are both very convenient.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of rail vehicle air conditioners, in particular to a manually adjustable air supply port for rail vehicle air conditioners. Background technique [0002] The so-called "rail vehicle" in the present invention mainly refers to the used vehicles of urban subway trains, light rail trains and intercity trains. With the development of urbanization worldwide, the construction of rail transit, including subway, light rail and intercity train, has become the development trend of public transportation in various countries. Rail trains not only need a good air-conditioning system, but also need a good ventilation environment to keep the rail cars comfortable. [0003] The existing rail vehicle air-conditioning air supply outlets, including the air-conditioning air supply outlets of the driver's cab, are basically non-adjustable air outlets, and their forms include square air outlets and circu...

Problems solved by technology

Its disadvantages are: (1) It can only be realized on a single side (2) The adjustment of the wind direction is accompanied by the adjustment of the air volume, and the two cannot be carried out independently; (3) The position of the fan blade will shift with the increase of the air volume; (4) Once the air outlet is installed , the wind direction adjustment surface will not be able to change
