Abstract

The utility model discloses a screwing clamping type detachable filter which has the advantages that the utility model can be disassembled and assembled to replace a filter core, can be repeatedly used for multiple times, the existing disposable filter can be updated into the detachable filter, waste can be used again, the utility model can be used for a long time, resources are saved, repeated production is reduced, and running cost for a locomotive is reduced. The utility model is characterized in that a casing is composed of an inner casing (6) and an outer casing (4) which can be mutually disassembled and assembled to be connected; the wall of the outer circumference of the inner casing is uniformly distributed with clamping convex points (5); the outer casing (4) is provided with corresponding guide slots (7); the bottom of each guide slot (7) is provided with a symmetrical arc slot (3) which is arranged along the circumference.

Description

The dismantled and assembled filter cleaner of swivel bayonet type

The utility model belongs to a kind of filtrating equipment in a kind of mushy stage separation field, specifically a kind of machine oil filtrating equipment of motor.

Existing filter cleaner.Can only use once, filter screen is stopped up back integral body by slag and scraps, and wastes very big.

The utility model purpose is to disclose the dismantled and assembled filter cleaner of a kind of swivel bayonet type.Its advantage is dismantled and assembled more renew cartridge, can be repeatedly used.Particularly can be used for the dismantled and assembled filter cleaner that is updated to existing disposable filter.Can turn waste into wealth, and permanent the use.Both save resource, reduced duplication of production.Reduce the locomotive operation expense again.

Below with reference to embodiment's description of drawings technological scheme.

Fig. 1 is the structure sectional view of existing disposable filter.

Fig. 2 is the sectional view of the utility model embodiment 1 housing parts.

Fig. 3 is the sectional view of the utility model embodiment 2 housing parts.

The dismantled and assembled filter cleaner of the utility model swivel bayonet type is by packing holder 1, base 2, housing, bypass valve 12, filter core 13, check valve 14 compositions such as grade.It is characterized in that: described housing is the inner housing 6 that connects by mutually can dismounting, frame 4 is formed, the outer circle wall that its inner housing near interface of described inner housing inserts section is evenly equipped with two or more clamping salient points 5 at least, described frame 4, the inner peripheral wall that inserts section at inner housing has the respective guide slots 7 that can supply inner housing clamping salient point 5 to insert, the bottom of each guide groove 7 is the arc shaped groove 3 of a symmetry shape along circumference, guide groove 7 is swallow-tail form inclined-plane 8 with the curve bath corner, have respectively in two housings interface one side at the two ends of curve bath that clamping salient point 5 with inner housing 6 is wide suitable to sink 9, inner housing is after guide groove is inserted into frame, arrive frame inner chamber depth location in inner housing forward position portion, the frame inwall has circular groove, two housings is installed in the groove connects the seal ring 10 that the back forms sealing.

Structure is at the renewal of thin-walled disposable filter and the scheme that designs as shown in Figure 2.It is characterized in that: be added with a stiffening ring 11 at inner housing 6 insertion section outer walls and/or frame 4 insertion section inwalls, promptly the guide groove of the clamping salient point 5 of inner housing 6 and frame and curve bath are all on this stiffening ring.

Structure shown in Figure 3 is that the frame and the base of the dismantled and assembled filter cleaner of described swivel bayonet type connects as one, and formation and housing be the part of the base of dismounting mutually, but one-step die casting.

The utility model is specially adapted to the renewal to disposable filter, can realize by following means.

Cut existing disposable filter housing, make it to become two-part.The inner housing outward edge add one the band salient point band, frame makes it to become frame with the level through the punching press pull and stretch, adds a groove band at the frame inward flange.

The utility model shell can adopt volume bucket formula structure, only needs punching press, and pull and stretch processing frame gets final product, and the frame depth as shallow is processed easily.After the frame machine shaping, add a groove band at inward flange, inner housing adds the sticking band salient point band of weldering at a side margin, then with the packing holder interlock behind volume bucket weld seam.This processing method is simple, and cost is low.It is extremely low to produce investment, and the efficient height.And existing disposable filter bucket must need through repeatedly punching press, and pull and stretch forms, and wastes a large amount of manpowers, material resources.The processing cost height.

But the moulding of the utility model base one-step casting, there is seal groove the frame upper end, and there is seal groove frame inside, but the equal casting of inner groovy, once drawing, flange.And existing filter cleaner needs through spot welding, and seaming constitutes, processing technology complexity, cost height.Need main equipment, a large amount of moulds, frock clamping, with high content of technology, the processing coefficient is big.

It is interior to right rotation to the limit that the utility model swivel bayonet type structure, salient point enter groove, and filter and filter base are screwed.Make the filter sealing simultaneously.In the vibrations of automobile can not make, frame was loosening, guarantees airtight.Can open filter separately when salient point is screwed into the groove ingress, whole filter can be taken down when salient point is screwed into left summit.
