Abstract
A lower end cover of a hydraulic filter comprises an end cover, and a through hole which is arranged in the middle of the end cover protrudes outwards. The outer end of the diameter of the through hole is small and the inner end of the diameter of the hole is large. A supporting ring is arranged at the inner end of the through hole and a seal ring is arranged between the wall of the through hole and the supporting ring. The structure of the through hole is formed by die-casting in one step, thereby production processes are simple, production efficiency is improved and the lower end cover is firmer. In addition, due to the facts that the supporting ring is mounted on the inner side of the through hole, even if welding spots fall off, the seal ring can't fall off and normal utilization is not affected. Furthermore, the supporting ring is positioned on the inner side of the through hole and is invisible commonly, so that appearance of the whole filter is more attractive.
Description
Technical field
The utility model relates to a kind of cleaner, relates in particular to a kind of hydraulic pressure cleaner bottom end cover device.
Background technology
Hydraulic pressure cleaner bottom end cover is located at the bottom of cleaner, plays the support fixation effect.Hydraulic pressure cleaner bottom end cover of the prior art, as shown in Figure 1 and Figure 2: it comprises end cap 1, is provided with through hole 4 in the middle of the end cap 1, and is welded with ring washer 2 in the outside of end cap 1, is provided with sealing ring 5 between this ring washer 2 and the end cap.This structure is welded, and welding portion 3 long-term stressed effects come off easily, cause sealing ring to drop, and cleaner can not normally be used.And welding portion 3 is in the outside of end cap 1, and it is attractive in appearance that welding portion 3 is exposed to the outside influence, and production process is also more loaded down with trivial details.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of hydraulic pressure cleaner bottom end cover of new structure is provided, and this end cap is more firmly attractive in appearance.
The utility model solves the technical scheme that its technical problem adopts: this hydraulic pressure cleaner bottom end cover, comprise end cap, and be provided with through hole in the middle of the end cap, this through hole is projection laterally, and its outer end, aperture is little, the inner big; End cap is provided with support ring in the inner of through hole, is provided with sealing ring between the hole wall of through hole and the support ring.The structure of this through hole forms by disposable die casting, and production process is simple, has improved production efficiency, and more firm.In addition, because support ring is installed in the inboard of through hole, even the solder joint place comes off, sealing ring can not drop yet, and does not influence normal use.Support ring is positioned at the inboard in addition, can't see usually, makes whole cleaner appearance more attractive in appearance.
Support ring is welded on the end cap.
The effect that the utility model is useful is: the utility model is rational in infrastructure simple, and result of use is good.Support ring is installed in the inboard of through hole, even the solder joint place comes off, sealing ring can not drop yet, and does not influence normal use.Support ring is positioned at the inboard in addition, can't see usually, makes whole cleaner appearance more attractive in appearance.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this hydraulic pressure cleaner bottom end cover, comprise end cap 1, be provided with through hole 4 in the middle of the end cap 1, this through hole 4 is projection laterally, and its outer end, aperture is little, inner big; End cap 1 is provided with support ring 6 in the inner of through hole 4, is provided with sealing ring 5 between the hole wall 4-1 of through hole 4 and the support ring 6.The structure of this through hole 4 forms by disposable die casting, and production process is simple, has improved production efficiency, and more firm.Support ring 6 is welded on the end cap 1, and support ring 6 is welded on the inboard of end cap 1, and end cap 1 inboard that welding portion is hidden does not affect the appearance.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
