Embodiment 1
[0044]A plugging structure of a filter screen and an inner frame, comprising an inner frame 5, an arc-shaped filter screen 1 and a frame structure 2 plugged with the filter screen 1, the frame structure 2 includes an end frame 21 and a frame 31, the The frame 31 is connected to the filter screen 1 through the plug-in structure 3. The plug-in structure 3 includes an outer plate 311, a connecting plate 32 and a splint 33. The outer plate 311 is integrally formed with the frame 31. The filter screen 1 The edge is plugged into the splint 33 and is fixedly connected with the splint 33 by a locking member, so that the filter screen 1 is conveniently disassembled, installed and replaced in case of blockage or the like. Both the clamping plate 33 and the outer plate 311 are plugged into the connecting plate 32 , which ensures the stability of the connection between the clamping plate 33 , the connecting plate 32 and the outer plate 311 . The inner frame 5 is a split structure installe...

The invention relates to the technical field of dust removal of transportation tools, and discloses an insertion structure of a filter screen and an inner frame and a ventilation device comprising thestructure. The insertion structure comprises an arc-shaped filtering net and a frame structure connected with the filtering net in an inserted mode. The frame structure comprises an end frame and a frame. The frame is connected with the filter screen through a plug-in structure, the plug-in structure comprises an outer plate, a connecting plate and a clamping plate, the outer plate and the frameare integrally formed, the edge part of the filter screen is inserted into the clamping plate and is fixedly connected with the clamping plate through a locking piece, and the clamping plate and the outer plate are both inserted into the connecting plate. The ventilation device solves the problems that an existing dust removal device is difficult in air intake and tedious in disassembly and assembly, and achieves the effects that internal elements of the ventilation device are stably connected, disassembly, assembly and maintenance are convenient, and electrical equipment in an equipment cabindissipates heat well.
Description
technical field [0001] The invention relates to the technical field of dust removal for vehicles, in particular to a plug-in structure of a filter screen and an inner frame and a ventilation device including the structure. Background technique [0002] In today's society, rail transportation mainly includes diesel locomotives, electric locomotives, EMUs, high-speed rail, passenger and truck carriages, light rails, subways and other transportation carriers, and road transportation mainly includes automobiles. Their normal operation needs to inhale a large amount of air to meet the needs of combustion of internal combustion engines, heat dissipation of electronic and mechanical components, and cooling of air conditioners and other facilities. With the inhalation of a large amount of air, there are a large number of floating objects such as dust, catkins, plant leaves, paper scraps, plastics, etc. in the air, which are adsorbed on the dust-proof devices of various air intakes i...
