Description

Filter shell with simplified structure Technical Field The utility model relates to the technical field of filters, in particular to a filter shell with a simplified structure. Background The filter is a component for filtering impurities, moisture and particulate matters in fuel oil, wherein water is easily mixed in due to the strong hydrophilicity of diesel oil, and therefore, a water accumulation cup is also commonly arranged in the diesel oil filter for collecting the water in the diesel oil. For the diesel filter on the market at present, the connection mode of ponding cup and filter body is generally, and filter body lower extreme is equipped with plastics lower cover and plastic connector respectively, and rethread plastic connector connects ponding cup, still need brush the glue when the assembly, and this kind of connection mode is more loaded down with trivial details, and part number is more, and the required mould of production is more, consequently needs to improve. Disclosure of utility model In view of the shortcomings of the prior art, the present utility model provides a simplified structure of a filter housing, which is used for solving the above-mentioned problems of the prior art. The utility model provides a filter shell with a simplified structure, which comprises a barrel, wherein an upper end cover and a water accumulation cup connecting piece which are distributed up and down are arranged in the barrel; The water accumulation cup connecting piece comprises a cover plate, a connecting plate, an internal thread sleeve and a locking ring which are distributed up and down and are integrally formed, the cylinder body is connected with the locking ring through a locking assembly so as to fix the water accumulation cup connecting piece in the cylinder body, the internal thread sleeve is used for being connected with the water accumulation cup, and water passing holes which are communicated in the internal thread sleeve are formed in the cover plate in a penetrating mode up and down. Preferably, the connecting plates are arranged in a plurality, the connecting plates are distributed at equal angles with the axis of the cover plate as the center, the upper side surfaces of the connecting plates are connected to the lower end of the cover plate, and the lower side surfaces of the connecting plates are fixed to the upper end surfaces of the internal thread sleeves. Preferably, the lower side of the cover plate is integrally formed with a ring, one inward end of the connecting plate is connected to the outer curved surface of the ring, and the ring is sleeved outside the water passing hole. Preferably, the outer end of the connecting plate is further integrally provided with a vertical rib which is vertically arranged, and the vertical rib is simultaneously connected with the inner thread sleeve and the outer curved surface of the cover plate. Preferably, the upper side of the cover plate is integrally formed with a vertical cylinder, the outer curved surface of the vertical cylinder is coplanar with the outer curved surface of the cover plate, and the vertical ribs extend upwards to the outer curved surface of the vertical cylinder. Preferably, the vertical rib is connected to the upper side of the locking ring downward.
