Description

The manual pipeline drainer of family expenses

The utility model relates to a kind of pipe-dredging machinery, the manual pipeline drainer of especially a kind of family expenses.

The machinery that is used for dredging pipeline in the prior art can be divided into electronic and manual two kinds by the power source category, a wherein electronic class is because its power demand is bigger, picture " energetically " board drain cleaner is received on the common 220V of the resident family circuit, particularly occur accidents such as tripping operation on the circuit in the old room in the 60 to 70's easily, and the sewerage in this class house limits the situation that obstruction occurs also very frequent because of its structure.With regard to manual pipeline drainer, the dredger that air pressure hydraulic pressure mediation mode is generally arranged, also there is guide head to stir the dredger of mode, the dredger of stirring mode generally is to connect a flexible axle by one handle, establish sharp-pointed cutlery or a less hook of a taper in the end of flexible axle, it is intended that and will gets lodged in it that foreign material in pipeline blend or hook goes out, foreign material in the general family pipeline accumulate over a long period, often stifled full whole pipeline cross section, the grease that solidifies is wherein arranged, the centre is adhering to such as hair, foreign material such as dish leaf with above-mentioned dredger front end less cutlery or hook, can not contact with tube wall is fine when dredging pipeline, the plug that forms with the obstruction at pipeline blocks up and gets out an aperture only, make pipeline for the moment unobstructed, but because the obstruction at close tube wall place is not touched, pipeline can stop up soon again.In addition, the flexible axle of existing manual stirring formula pipeline drainer and the connecting structure between handle and the guide head be more complicated all, and performance is very unreliable, and dismounting is also inconvenient.

The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of obstruction handle and the flexible axle wherein that can thoroughly remove in the pipeline to connect reliably the manual pipeline drainer of the family expenses of easy accessibility.

For achieving the above object, the utility model is taked following design proposal:

The manual pipeline drainer of family expenses includes handle, spring and guide head, and described guide head is little, broad in the middle, the fairshaped jatharapanvartanasana spring bodies in front and back, and its rear end extends a straight tube spring section; Described spring is a straight tube shape, play flexible axle exactly, the diameter of the spring section that its front end and described guide head rear end extend and spring spacing are complementary and peg graft fixing, the spring silk of the spring section on the guide head and the spring silk of described spring are respectively pitched together one by one, such connecting mode is relatively reinforced, and dismounting is also more convenient.Described handle is made up of taper knob, elasticity locking core and locking cap, and described taper knob is a hollow tubular; Plug in the pipe of its front end and axially locating one elasticity locking core, it is a hollow tubular, have cannelure on the tube wall of the front end of described elasticity locking core, so that make front end that contraction elasticity be arranged, cannelure can leave four roads along circumference and constitute cross, described elasticity locking core front end is one section caliber from fine to coarse transition section backward in the past vertically, the length of described cannelure is greater than the length of the described transition section on the elasticity locking core, the rear end of described spring is inserted in the front end of described elasticity locking core, outside sheathed one vasiform locking cap at described elasticity locking core, the front end caliber of locking cap also has in the past from fine to coarse a transition section backward, the transition section of the caliber of its tapering and described elasticity locking core front end is complementary, and the rear portion and the taper knob of locking cap are spirally connected.By locking cap is constantly screwed on taper knob, the outer wall of the front end transition section of the leading portion transition section inwall extruding elasticity locking core of locking cap, owing to have cannelure, make the front end of elasticity locking core have elasticity, then shrink after being squeezed, thereby the rear end of described spring is clamped on the handle securely.

The caliber transition section of described elasticity locking core and locking cap is the arc transition section vertically.The elastic performance of arc transition section is better than straight shape transition section.

When using this dredger to carry out pipe-dredging, described spring is arranged in the hollow tubular of taper knob, pull out the spring of certain-length as required by the handle front end, with locking cap the spring rear portion is clamped on the handle then, the fixing described guide head of front end grafting at spring injects pipeline with guide head then.The curved edge of fairshaped guide head can well coincide with the shape at the turning of pipeline, makes this dredger in pipeline, and especially resembling turning such as return trap can pass through smoothly.In addition, this guide head can contact more with tube wall, to being bonded at the effect preferably that scraped of foreign material on the tube wall.For can being hooked the foreign material that scrape off, guide head is drawn out pipeline then thereupon, the gap of the adjacent spring silk of the spring body of guide head can be 2-10mm, the surface that so is worth little spring body too is because smooth, the foul of losing control of one's feelings, the ability of then scraping foreign material also can descend, but this value is too big, and the rigidity of guide head will reduce, and the ability that penetrates obstruction will weaken.Operator limit handle with sleeve, the limit pushes spring to the pipeline depths, spring length as reservation is not enough, then unscrew locking cap, by pulling out one section spring in the handle sleeve again, screw locking cap then again and get final product, at last spring and guide way are pulled out the foreign material that hook on the pipeline cleaning guide head together, whole dredger all cleaned up split into handle, spring and guide head are collected.

Handle with sleeve and rotational lock cap can be made vertical raised and concave figures when dredging for convenience on the outer wall of handle and locking cap.

Simple in structure, the easy accessibility of the manual pipeline drainer of the family expenses that the utility model provides connects reliably between each parts, can thoroughly remove the obstruction in the pipeline, for people's life provides convenience.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment:

As shown in Figure 1, this dredger is made up of handle, spring 2 and guide head 3, and described guide head 3 is front and back streamlined jatharapanvartanasana spring bodies little, broad in the middle, and the gap of its adjacent spring silk is 7 millimeters, rear end extends a spring section 3-1 on it, connects firmly (as shown in Figure 4) with the front end fork-join of spring 2.Taper knob 1 is a hollow tubular, and its anterior inner tube wall is provided with convex shoulder 1-0, inserts elasticity locking core 1-1, axially locating on convex shoulder 1-0 at taper knob 1 front end.Elasticity locking core 1-1 is a hollow tubular, and its anterior caliber is gradually big with the arc Changing Pattern after by forward direction, has four cannelure 1-1-1 on the front end tube wall, and its length changes the length (shown in Fig. 2,3) of transition section greater than the arc on the elasticity locking core.Locking cap 1-2 is established in outside at elasticity locking core 1-1, after the front portion of locking cap 1-2 has the caliber that is complementary with elasticity locking core 1-1 front portion by forward direction with the gradually big transition section of arc Changing Pattern, on the inner tube wall at locking cap rear portion and be provided with the screw thread of mutual coupling on the pipe outer wall of taper knob front end.
