Abstract
The utility model relates to a centrifugal oil filter assembly device for a large diesel engine, in particular to a centrifugal oil filter with a locking mechanism, which mainly solves the problem that in actual work, because the centrifugal oil filter is only locked by threads, so that the centrifugal oil filter may fail to work in speed rotation and intense vibration. In order to solve the technical problem, the centrifugal oil filter with the locking mechanism has the technical scheme that: the centrifugal oil filter with the locking mechanism comprises an outer shell and a base; a rotor filter element is arranged in the outer shell; a rotor shaft passes through the rotor filter element and is screwed and fixed by a screw cap on the top of the outer shell through threads; the centrifugal oil filter with the locking mechanism is characterized in that the bottom of the outer shell is provided with a flange; a plurality of buckles with stopping sides are arranged on the outer side of the bottom of the flange around the circumstances; a circumferential surface which is butted with the base is provided with a plurality of slots which are matched with the buckles; a round of locking slots are arranged on a base wall below the slots; and the buckles pass through the slots, rotate along the locking slots and lock the outer shell and the base. In order to improve the sealing performance, rubber seal rings are arranged on the circumferences which are butted with the outer shell and the base, and the compression force locks the slots. The centrifugal oil filter with the locking mechanism can greatly improve the reliability of an oil filter assembly.
Description
Technical field
The utility model relates to the spin-on oil filter assembly device that large-scale diesel engine is used, the particularly spin-on oil filter of tight mechanism with lock.
Background technique
At present at spin-on oil filter on the market in real work since in the centrifugal oil strainer real work single with thread locking may since inefficacy arranged under the vibration of speed rotation and accompanied by intense may.Thereby so on original thread locking basis, increase the risk of draw-in groove locking reducing greatly product assembly.
Summary of the invention
The purpose of this utility model provides a kind of spin-on oil filter of tight mechanism with lock, mainly solves existing filter cleaner and depends merely on its part of thread locking technical problem that the assembly parts reliability reduces under the situation of high speed rotating and judder.
The technological scheme that its technical problem that solves the utility model adopts is: the spin-on oil filter of tight mechanism with lock, comprise shell and base, the rotor filter core is installed in the enclosure, rotor shaft passes the rotor filter core and spins fixing by cover top portion nut screw thread, it is characterized in that outer casing bottom band flange, the buckle of a plurality of band stop edge is set along circumference in the flange bottom outside, at base butt joint circumferential surface draw-in groove a plurality of and the buckle coupling is set, draw-in groove below base wall is provided with all locking slot, and buckle passes draw-in groove and rotates shell and base locking along locking slot.For improving sealability, to dock circumference at shell with base rubber seal is set, its impacting force makes draw-in groove lock.
The beneficial effects of the utility model are: set up the draw-in groove locking on the basis that does not change original assembly structure and boundary dimension, increase product reliability greatly by dual locking mechanism.

Fig. 3 is the utility model base draw-in groove structural representation.
Among the figure: 1-nut, 2-shell, 3-rotor filter core, 4-rotor shaft, 5-rubber seal, 6-base, 7-draw-in groove, 8-buckle, 9-stop edge, 10-locking slot.
Embodiment
With reference to Fig. 1,2,3, the spin-on oil filter of tight mechanism with lock, comprise shell 2 and base 6, rotor filter core 3 is installed in the shell 2, rotor shaft 4 passes rotor filter core 3 and spins fixing by nut 1 screw thread at shell 2 tops, shell 2 bottom band flange, the buckle 8 of a plurality of band stop edge 9 is set along circumference in the flange bottom outside, at base 6 butt joint circumferential surfacies draw-in groove 7 a plurality of and the buckle coupling is set, draw-in groove below base inner wall is provided with all locking slot 10, and buckle 8 passes draw-in groove 7 and rotates shell 2 and base 6 lockings along locking slot 10.For improving sealability, to dock circumference with base at shell rubber seal 5 is set, its impacting force makes draw-in groove lock.Spin-on oil filter according to the rules assemble sequence and after requirement installs, because the nut 1 on shell 2 tops provides a kind of locking that is connected with thread locking between the rotor shaft 4.Simultaneously because the rotor filter core 3 of the working principle enclosure of centrifugal oil strainer rises and high speed rotating counterclockwise, also have a trend that is rotated counterclockwise at the drive lower casing 2 of this driving force when work.In order to prevent that regular screw threads from making screw thread get loose under the effect of this trend power, we are the closely-pitched left-hand thread with this screw thread design, utilize this counterclockwise trend power further to increase screw-down torque when strengthening thread locking power.
Correct install the back by buckle 8 structural limitations of base draw-in groove 7 and shell 2 freely getting loose between shell 2 and the base 6, and if only if, and situation lower casing 2 and base 6 that draw-in groove 7 aims at buckle 8 can be disassembled.Simultaneously because the rotor filter core of the working principle enclosure of centrifugal oil strainer rises and high speed rotating counterclockwise, also have a trend that is rotated counterclockwise at the drive lower casing of this driving force when work.Draw-in groove is aimed at buckle and situation about losing efficacy when driving shell rotate freely counterclockwise under extremity for anti-driving force here, and we are provided with freely rotating of stop edge 9, limit stoper limit shell on the buckle of shell.And require the extremely function maximization of this structure of spacing promise under original state of manual insertion when assembling.
