Description

Automatic-closing water saving tap

The utility model relates to a kind of tap that is contained on the running water pipe, particularly promotes the self-closing link water tap that manger board is opened with the flat push rod force transmission mechanism of flat axle.

Traditional tap is closed because of forgetting after opening, and regular meeting causes the loss and the waste of tap water.For this reason, people have manufactured and designed various self closing water-saving taps, still, and these water conserving taps or too high or use difficulty thereby be difficult to be accepted by people because of opening effort because of the complex structure cost.Promote the self closing water-saving tap that valve rod is opened as a kind of directly press...with one's finger on handle, open very effort, and must continue after opening that firmly tightly withstanding handle could continue flowing water.Therefore, use very inconveniently, even old man and children can't use.For above-mentioned reasons, greatly limiting its popularization and use.

The purpose of this utility model is to provide a kind of self-closing link water tap laborsaving, easy to use of opening.It not only can accomplish to loose one's grip self-closing, and unlatching is laborsaving flexibly, uses easy and convenient.

The purpose of this utility model is achieved by the following scheme:

One has an annular boss with the identical valve body of traditional leading shape, a pilot hole is arranged behind this boss on its inwall.One end has flat top board, and the other end has the valve rod of manger board to be contained in the pilot hole, is with Returnning spring on the valve rod.One end of Returnning spring is pressed on the flat top board, and the other end is pressed on the support of pilot hole.The flat shaft portion of flat push rod and handle shaft is close together, and they and valve rod, pilot hole constitute the flat push rod force transmission mechanism of flat axle jointly.Handle shaft is stretched out its end of valve body rotatable handle is housed, and when nature, Returnning spring is upheld, and manger board is pressed on the annular boss, and tap water can not flow in the valve body.Rotatable handle, handle shaft drive the flat push rod force transmission mechanism motion of flat axle, the Returnning spring compression, and manger board leaves annular boss, and tap water flows through annular boss and enters in the valve around manger board, flow out from weep hole.Release handle, under the acting in conjunction of Returnning spring and current, manger board is pressed on the boss again, returns to nature.

In such scheme, pilot hole should connect together by pole and boss or valve body, to guarantee having enough gaps to allow flowing water pass through between them.Also can be cast as one pilot hole and annular boss separately as valve core, and then in the valve body of packing into.

The utility model is owing to adopted the flat push rod force transmission mechanism of flat axle, its using method and profile structure is with traditional leading just the same, therefore easilier accepted by people psychologically, and since handle radius several times of the present utility model ground greater than the turning radius of flat axle, so be very easy to when opening laborsaving.Simultaneously since when opening be not push away, by handle, but therefore rotatable handle uses the custom that more meets people, it is flexible more to seem.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the main sectional view of the utility model in off position the time.

Fig. 2 is the main sectional view of the utility model when opening state.

Can see that from Fig. 1 and Fig. 2 the encapsulating method between the connecting means of handle of the present utility model (1) and handle shaft (2) and handle shaft (2) and the valve body (3) is no longer set forth with traditional leading just the same here.

Comparison diagram 1 and Fig. 2 as can be known, Fig. 1 is pilot hole (7) and annular boss as the valve core casting together, in the valve body of packing into then.Fig. 2 is pilot hole (7) and annular boss is direct and valve body is cast together.

As shown in Figure 1, when natural closed condition, under the pressure acting in conjunction of manger board (10) tap water in the pressure of Returnning spring (6) and pipeline, be pressed in tightly on the annular boss (9), tap water can not flow in the valve body (3).It is also parallel that the plane of flat axle this moment (4) and flat top board (5) flat pressed close to.Rotatable handle (1) handle shaft (2) is rotated simultaneously, and the plane of flat axle (4) is flat vertical by parallel steer with flat top board (5).Returnning spring (6) is compressed, and valve rod (8) moves forward along pilot hole (7), and manger board (10) leaves annular boss (9), and tap water flows through annular boss (9) and enters in the valve body (3) around manger board (10), flow out from drain opening.When handle (1) half-twist, reach state shown in Figure 2, under this state, the convex surface of flat axle (4) and flat contact of flat top board (5), the plane of flat axle (4) and the flat vertical of flat top board (5) and with the parallel axes of valve rod (8), therefore, just can guarantee continuous flowing water as long as buttress handle (1) gently.Release handle (1), valve rod (8) move backward along pilot hole (7) under the acting in conjunction of Returnning spring (6) and current, and flat top board (5) promotes flat axle (4) and handle shaft 2 is rotated together, returns to natural closed condition shown in Figure 1 again.

Can also see that from Fig. 2 the plane of flat axle (4) can be made eccentric with respect to the axis of handle shaft (2).Rotate 180 ° under state shown in Figure 2 makes flat axle (4) shorter and smaller convex surface contact with flat top board (5), just can obtain less current.

In sum, the utility model is not only opened laborsaving, closes flexibly, and is easy to use, and rational in infrastructure, easy to manufacture, and its profile structure is with traditional leading just the same, accepted by people easilier, can be extensive use of in various places.

Claims (3)

1, a kind of tap that is contained on the running water pipe, it comprises handle, handle shaft, valve body and is positioned at valve rod and the Returnning spring that valve body has manger board.It is characterized in that: handle shaft and valve rod make the rotating force that acts on the handle shaft change into end thrust on valve rod by the flat push rod force transmission mechanism of flat axle, and actuate valve stem moves.

2, tap according to claim 1 is characterized in that an end of valve rod armrest arbor has a flat top board, the flat push rod of the common formation of this flat top board and valve rod.

3, tap according to claim 1 is characterized in that handle shaft stretches into valve body and partly has to be a flat axle.
