The invention discloses a filter screen device, an air conditioner and a railway vehicle, the filter screen device comprises a filter screen mounting frame and a filter screen detachably arranged on the filter screen mounting frame, two long edges of the filter screen are respectively provided with at least one clamping column, and the clamping columns are arranged along the width direction of thefilter screen; at least two clamping grooves capable of being clamped with the clamping columns in a one-to-one matching manner are formed in the filter screen mounting frame, the clamping grooves are formed in local positions of the long edges of the filter screen mounting frame, each clamping groove is provided with a clamping part in positioning fit with the corresponding clamping column and aguide part for guiding the corresponding clamping column to get in and out of the corresponding clamping part, and the guide parts are arranged in the thickness direction of the filter screen; and the filter screen mounting frame is provided with a limiting piece for limiting the clamping column on the clamping part, and the limiting piece is detachably fixed on the wide edge of the filter screenmounting frame. The clamping columns of the filter screen move in the thickness direction of the filter screen to be clamped into and separated from the clamping grooves of the filter screen mountingframe, and the filter screen does not need to be pushed and pulled in the whole length direction, so that the push-pull distance of the filter screen relative to the filter screen mounting frame is shortened, and the filter screen is convenient to disassemble and assemble.

    本发明公开一种滤网装置、空调和轨道车辆,滤网装置包括滤网安装框和可拆卸地设置在滤网安装框上的滤网,滤网的两个长边上分别设有至少一个卡接柱,卡接柱沿滤网宽度方向布置;滤网安装框上设有能够与卡接柱一一配合卡接的至少两个卡槽,卡槽布置在滤网安装框长边的局部位置,卡槽具有与卡接柱定位配合的卡接部和导向卡接柱出入卡接部的导向部,导向部沿滤网的厚度方向设置;滤网安装框上设有用于将卡接柱限位在卡接部的限位件,其可拆卸地固定在滤网安装框的宽边上。本发明通过使滤网的卡接柱沿滤网厚度方向移动,实现卡入和脱离滤网安装框的卡槽,无需沿整个长度方向推拉滤网,从而缩短了滤网相对滤网安装框的推拉距离,方便滤网的拆装。
