Description

A kind of structure improved water strainer

Technical field

The utility model relates to a kind of water strainer, particularly a kind ofly can simple and easyly align firm combination, and the structure improved water strainer of the good difficult generation loose or dislocation of structural strength.

Background technology

Existing water strainer of a great variety, wherein has best pure water supply effect with RO reverse osmosis water strainer, be a known reverse osmosis water strainer structure as shown in Figures 1 and 2, can hold to go into for filtering core tube 3 by outer cylinder body 1, and give combination with lid 2, lid 2 inside are provided with prosopyle 2a and posticum 2b, and this prosopyle 2a is communicated with an oblique cone shape centre hole 2c, branches such as other lid 2 bottoms are provided with plural L shaped fit slot 2d, L shaped fit slot 2d has vertical channel and level trough, can insert and rotate for the set plural projection 3a in filtering core tube 3 outer rims upper ends, and rest on the level trough position, filtering core tube 3 tops are provided with the centre hole 2c that conical nose 3b can enter lid 2, and this conical nose 3b outer rim is nested with O shape ring 3c.

Aforesaid known reverse osmosis water strainer structure, have following defective: (one) though its filtering core tube 3 by the L shaped fit slot 2d button knot of projection 3a and lid 2, but this design only can provide easy location (effect of similar hook), and can't reach the effect of firm combination and packing, and the volume of its projection 3a is little, so be easy to assemble or produce when stressed the situation of fracture; (2) its filtering core tube 3 and lid are 2, be to paste by the nested O shape of conical nose 3b outer rim ring 3C and oblique cone shape centre hole 2c wall to support and reach leakage-proof effect, thereby the possibility of seepage is easily arranged because of scale error.

And for example United States Patent (USP) the 4th, 956, shown in 086, is the filter structure of another known reverse osmosis water strainer, though its register hole that can borrow two buckle fins of filtering core tube head to wear iron plate screws snap fit; But, when its iron plate is subjected to two buckle fin snap fit of filtering core tube head, Yi Yin is stressed and produce distortion, and then cause the buckle steadiness not good, the possibility that seepage is arranged between lid and filtering core tube head, moreover there is no localized design when its two buckles fin and iron plate snap fit, thereby screw to align and be difficult for and easily produce loose or dislocation.

The utility model content

In view of this inventor is actively constantly studied improvement, and through inquiring into and study specimen test in many ways, and repeatedly revise improvement, and release the utility model, be used to solve the problem that leakage problems between filtering core tube head and lid and lid align difficulty and easily produce loose or dislocation.

The utility model provides a kind of structure improved water strainer, it comprises a filtering core tube and a lid, wherein the filtering core tube upper end is provided with a head, this head is by the nearly peripheral region of a disc end face one annular groove to be set, the end face center is convexly equipped with one or two scalariform shrinking section, rank, the big footpath of shrinking section end face is provided with some prosopyles, the sheathed waterstop ring in periphery upper end, the relative both sides of periphery respectively are provided with a horizontal U-shaped and fasten fin, shrinking section path rank end face is provided with a posticum in addition, the sheathed waterstop ring in periphery upper end, the relative both sides of lid are provided with a water supply connector and a water out adapter, the bottom surface is provided with a fit slot and two locking holes, and the hypomere periphery is provided with relative two card knot holes and communicates with fit slot, and respectively forms a card knot sheet in two card knot holes; Whereby, can be simple and easy that lid is sleeved on the fixed plate knot of locking is fixing, the shrinking section with the filtering core tube head is rotated snap fit with the fit slot cover merging of lid again, makes shrinking section rely on two waterstop rings closely to be sleeved on the fit slot inner edge of lid, finishes assembling.Wherein the nearly peripheral region of disc end face of filtering core tube head is provided with an annular groove; The card knot hole system of lid is made of in being interconnected than hyphen cylindrical void one end a long horizontal stripe hole and a hyphen cylindrical void, and forms a card knot sheet between long horizontal stripe hole and hyphen cylindrical void; The horizontal U-shaped of rank, the big footpath of filtering core tube shrinking section periphery fastens fin, and laterally ㄈ shape fastens the fin replacement; The lid bottom surface is provided with two locking holes; Lid is sandwiched on the fixed plate with its two cards knot borehole jack and locks, and this fixed plate is provided with the U-shaped breach, and U-shaped breach both sides are provided with screw.

Advantage of the present utility model is:

1, can guarantee ne-leakage between filtering core tube head and lid; Be to adopt overlapped way to insert and put buckle between the shrinking section of its filtering core tube head and the fit slot of lid, linking steady character and structural strength are good, are difficult for because of stressed generation distortion, thereby have guaranteed ne-leakage between filtering core tube head and lid.

2, lid aligns simple and easy and difficult generation loose or dislocation; During the fit slot buckle of the shrinking section of its filtering core tube head and lid, can borrow the horizontal U-shaped of filtering core tube head to fasten fin and the card of lid and tie the sheet fit and fasten and reach the location, thereby solve the problem that lid aligns difficulty and easily produces loose or dislocation.
