Description

Technical Field

[0001] The utility model relates to the technical field of dustproof air compressors, in particular to a dustproof air compressor. Background Art

[0002] An air compressor is a device used to compress air. When the air compressor is started, the motor shaft of the motor inside the air compressor drives the piston to move up and down through the connecting rod, thereby compressing the gas in the piston chamber and sending the compressed gas into the gas storage tank for use. In order to prevent dust, existing air compressors are equipped with a dust cover structure on the outside of the air compressor body.

[0003] However, the existing dust cover structure is generally fixed to the outside of the air compressor, for example, by bolting or welding. This installation method of the dust cover is not convenient for the later maintenance of the air compressor, and a filter is usually arranged on the side of the existing dust cover at the air intake of the air compressor to filter large impurities in the air. The installation method of this filter is generally also installed by screws, and can only be replaced when the air compressor is shut down, resulting in delays in normal work. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the installation method of the existing air compressor protective cover is relatively simple, which is inconvenient for the maintenance of the air compressor, and is inconvenient for replacing the filter screen and the filter screen cannot be replaced without stopping the machine.

[0007] As a further solution of the utility model: an air vent is provided on one side of the dust cover at the dust filter plate, and limiting guide rails are fixed on the upper and lower sides of the air vent to limit the position of the dust filter plate, and the dust filter plate is slidably arranged between the limiting guide rails, and long plug-in holes are provided on one side of the dust cover on both sides of the air vent, and baffles are inserted in the long plug-in holes, and the baffles can slide in the long plug-in holes.

[0008] As a further solution of the utility model: a limiting guide hole is provided on one side of the baffle, and four stoppers are symmetrically fixed on the upper and lower sides of the baffle to prevent the baffle from escaping from the limiting guide hole.

[0009] As a further solution of the utility model: the width of the limiting guide hole is greater than the width of the dust filter plate, the height of the limiting guide hole is greater than the height of the dust filter plate, the lower side of the limiting guide hole is flush with the lower side of the limiting guide rail located below, which can facilitate the dust filter plate to pass through the limiting guide hole.

[0010] As a further solution of the utility model: arc grooves are provided below both sides of the dust cover, and a push handle is fixed to one side of the dust cover for moving the device.

[0011] Compared with the prior art, the advantages of the utility model are: the utility model adds a locking structure and a hinged structure.
