Description
Technical field
The utility model relates to a kind of oil sump jettison gear.
Background technique
The particular/special requirements such as some vehicle is arranged the space of diesel engine in order to meet, lubricating oil capacity, the oil sump shape meeting more complicated of diesel engine, adopts common steel plate punched technique to be difficult to realize, often adopts the oil sump of aluminium material in this case.Oil sump must be provided with drain oil and regularly replace lubricant oil for diesel engine, and the easiest method directly on oil sump, arranges a tapped through hole, seals, more unclamp during oil change and tighten plug screw with plug screw and packing ring.Although this method is simple, convenient, because aluminium material is softer, plug screw is repeatedly tightened at screw place and is dismantled, and very easily causes the screw thread of screw to be slided tooth and destroys, cannot install purge cock again, cause oil sump to lose efficacy.
For the risk of screw thread destruction easy to slip teeth, general employing directly first inlays a steel wire lining on the tapped hole of oil sump, then plug screw is installed the mode on oil sump, adopts composite-gasket to seal between plug screw and oil sump.The drawback of this method is, in order to inlay steel wire lining, the screw of oil sump itself will add large gauge, but the screw of the specification of plug screw and common composite-gasket just and after having inlayed steel wire lining mates, common composite-gasket by the gap sealing between steel wire lining and oil sump, cannot cause leakage of oil.If composite-gasket is designed to special structure, the administration cost of part rises, and meanwhile, because packing ring difference is not obvious, diesel engine after market very easily occurs situation about replacing with common composite-gasket, thus is difficult to the sealing ensureing drain oil place.
Chinese patent " has the oil sump in special purge cock hole " (application number 201120562894.5), disclose a kind of oil sump with special purge cock hole, purge cock seat is instead of with steel-wire screw-socket, and eliminate a plain washer, with gasket seal between steel-wire screw-socket and oil sump, have the following disadvantages in this patent: (1), if the pad flat cylinder pad that is common metal, the oil flowed out from screw thread cannot be sealed; (2) if the composite-gasket of the standard of employing, because plug screw screw-thread ending part is for processing factors, one tool withdrawal groove must be had, and the diameter of tool withdrawal groove is less than the major diameter of thread of plug screw, the internal diameter of composite-gasket is identical with major diameter of thread, the axially locating between composite-gasket and plug screw is caused to there is deviation, local location generation composite-gasket is not pressed in for the rubber of sealing oil the outside of oil sump tapped hole completely, part oil can be flowed out from composite-gasket along screw thread; (3) if position packing ring by purge cock being arranged step, increase the processing cost of plug screw, complex structure, this step generally can be very short, the structures shape of standard Composition spacer its in fact cannot to be fixed on this step when assembling, do not have the effect of location, the easy pad that makes when tightening is stuck on step on the contrary, destroys composite-gasket; (4) avoid above hidden danger according to special composite-gasket, because pad is once become non-standard component, just very easily in the situation that after market generation substitutes with common standard part, be difficult to ensure sealing.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel oil sump jettison gear, effectively prevent purge cock and repeats to tighten and dismantle the risk causing aluminium matter oil sump drain oil thread failure.
For achieving the above object, the utility model adopts following technological scheme:
A kind of oil sump jettison gear, comprises the threaded bushing of logical structure in having, and what described threaded bushing was arranged on oil sump drains the oil in screw, and threaded bushing is provided with internal thread and outside thread; Purge cock is arranged in threaded bushing in logical structure, and matches with the internal thread of threaded bushing; The side of described threaded bushing and oil sump phase-contact surface is provided with O type ring recess, and the face that described threaded bushing and oil sump contact is vertical with the axial direction of purge cock, is provided with the O type circle for sealing thread lining and oil sump in described O type ring recess.
Described O type ring recess is arranged at the threaded bushing side of threaded bushing and oil sump phase-contact surface;
Described O type ring recess is arranged at the oil sump side of threaded bushing and oil sump phase-contact surface;
The outside thread of described threaded bushing matches with the screw thread of the screw of draining the oil of oil sump;
Composite-gasket is adopted to seal between described purge cock and threaded bushing;
Described O type ring recess is arranged along the axisymmetrical of purge cock;
The internal diameter of described O type ring recess is greater than the external diameter of the screw of draining the oil on oil sump.
Threaded bushing, before being screwed into oil sump, its outside thread being coated with thread locking adhesive and preventing plug screw to be unscrewed in the process of repeated removal, also can play the effect of the thread pitch between seal cartridge and oil sump simultaneously.
The beneficial effects of the utility model:
(1) jettison gear of the present utility model, adopt O type circle to seal between its threaded bushing and oil sump, the internal diameter of O type ring recess is greater than the external diameter of the screw of draining the oil on oil sump, when there being oil to be outbound flowed by screw thread, utilize O type circle that oil catch is lived, ensure that sealing; Adopt O type circle to seal another benefit to be, relative to pad, the more exquisite matching of assembling of O type circle, to be difficult to load in groove with O type ring recess unmatched O type circle or compacted, just can find whether employ suitable O type circle, avoid misloading in time in assembling.
(2) adopting jettison gear of the present utility model, only need unscrew purge cock and the lining that do not unscrew when draining the oil, thus effectively avoid threaded bushing to repeat to tighten and dismantle the risk causing aluminium matter oil sump drain oil thread failure.
(3) adopt common composite-gasket to seal between purge cock and threaded bushing, ensure that the effect that just can reach sealing with common part.
