Description
Technical field
The utility model relates to a kind of oil filter.
Background technique
In motor car engine working procedure, carbon distribution oxidized under metal filings, dust, high temperature and gelatinous precipitate, water etc. are constantly mixed into lubricant oil, the effect of oil filter is exactly filter these mechanical admixtures and colloid, protects the clean of oil to be lubricated, extends its life time.The ubiquitous deficiency of existing oil filter has: structure relative complex, insufficient strength, and sealing is poor, and sealing sealing easily departs from seal ring, is also unfavorable for assembling.
Summary of the invention
In view of the deficiency that background technique exists, the purpose of this utility model is intended to provide that a kind of structure simple strength is high, good airproof performance, sealing sealing location are reliable, the band power-assisted button oil filter that is beneficial to assembling.
The utility model takes following technological scheme:
Band power-assisted button oil filter, comprise housing, seal ring, thread plate, element kit and power-assisted button, seal ring is located at the upper shed of housing, power-assisted button is located at the bottom of housing, thread plate is fixed on the bottom surface of seal ring, thread plate establishes center oilhole and side to put oilhole, non-return diaphragm seal is established in the bottom that oilhole is put on side, described element kit comprises center tube, refill, refill upper cover and refill lower cover, the bottom of element kit is provided with spring, it is characterized in that: described seal ring is welded to connect the upper shed at housing with brazing mode, described non-return diaphragm seal is connected with seal ring and is structure as a whole with seal ring, seal ring set is located at the top of center tube, seal ring upper-end surface contacts with the bottom surface of thread plate to put between oilhole at center oilhole and side and forms isolating seal, described power-assisted button is made up of the sheetmetal striking out semi-spherical shape, hemispherical central authorities offer cutting groove.
The upper-end surface of described seal ring is provided with opening slot to hold sealing sealing, and sealing is sealed in inner ring bottom position and is provided with back-up ring body, and opening slot is provided with interior side flanging at tip position to be undertaken protecting by back-up ring body.
After adopting technique scheme, the attainable Advantageous Effects of the utility model is: be 1. welded to connect by brazing mode between seal ring and the upper shed of housing, first the structure of seal ring and housing upper shed can be made to be simplified, join strength is high, can guarantee outside seal reliability simultaneously; 2. non-return diaphragm seal is connected with seal ring and is structure as a whole, and not only structure is simple, is also conducive to filter cleaner inner sealing; 3. the structure of power-assisted button is simple and compact, stretches in cutting groove to carry out pulling can screw or unclamp filter cleaner during installation by screw-driver, is beneficial to assembling; 4. sealing is sealed in seal ring opening slot and obtains well spacing and prevent from, and location is reliable.
