In order to achieve the above object, the technical scheme adopted in the present invention is:

A self-extending faucet, comprising a fixed pipe, a movable pipe and a fixed pin, the left end of the movable pipe is arranged inside the fixed pipe, the right end is arranged outside the fixed pipe, the left end of the movable pipe is provided with an annular plate, and the annular plate is connected to the right side of the fixed pipe. A spring I is arranged between the walls; one end of the fixed pin is provided with a pin cap, and the end of the other end passes through the side wall of the fixed tube, and the fixed pin is arranged between the ring plate and the right wall of the fixed tube, and the fixed pin passes through the right wall of the fixed tube. The end passing through the fixed pipe is a slope, the right end of the slope is flush with the inner wall of the fixed pipe, and the right end is arranged between the fixed pipe and the movable pipe.

The spring I is a tension spring.

An elastic pull piece is arranged between the annular plate and the left wall of the fixed pipe.

A spring II is arranged between the pin cap and the outer wall of the fixed pipe.

The elastic coefficient of the elastic pull member is smaller than that of the spring I.

A sealing ring is provided on the outer side of the annular plate.

A washer is arranged between the annular plate and the right wall of the fixed pipe.

The spring II is a tension spring.

The fixed pipe is a hollow cylindrical pipe, and the left wall and the right wall are respectively provided with a water inlet hole and a water outlet hole, and the left end of the movable pipe passes through the water outlet hole on the right wall and is arranged in the fixed pipe.

Owing to adopted above-mentioned technical scheme, the beneficial effect of the present invention is:

The invention is simple in structure, convenient to use, saves space, and can be extended automatically. The movable pipe can be extended into the fixed pipe when not in use, and drawn out again when in use. In order to prevent the movable tube from being ejected too fast and causing harm to people, the elastic puller can give the movable tube a certain pulling force when the movable tube is ejected, so as to reduce the ejection speed of the movable tube.

detailed description

Below in conjunction with accompanying drawing, the present invention is described in detail.

Example 1

As a preferred embodiment of the present invention, referring to accompanying drawings 1 to 3 of the specification, this embodiment discloses a self-extending faucet, which includes:

A self-extending faucet, comprising a fixed pipe 1, a movable pipe 2, a fixed pin 6 and a pressure rod 9, the left end of the movable pipe 2 is arranged inside the fixed pipe 1, the right end is arranged outside the fixed pipe 1, and the left end of the movable pipe 2 An annular plate 3 is provided, and a spring I4 is arranged between the annular plate 3 and the right wall 102 of the fixed pipe 1; one end of the fixed pin 6 is provided with a pin cap 61, and the end of the other end passes through the side wall 103 of the fixed pipe 1 , and the fixed pin 6 is arranged between the annular plate 3 and the right wall 102 of the fixed tube 1, the end of the fixed pin 6 passing through the fixed tube 1 is a slope, the right end of the slope is flush with the inner wall of the fixed tube 1, and the right end is arranged on the Between the fixed pipe 1 and the movable pipe 2; the pressure rod 9 is arranged parallel to the pin cap 61, the left end of the pressure rod 9 is an inclined plane, and the lowest point of the inclined plane is arranged under the pin cap 61.

Example 2

As a preferred embodiment of the present invention, referring to accompanying drawings 1 to 3 of the specification, this embodiment discloses a self-extending faucet, which includes:

A self-extending faucet, comprising a fixed pipe 1, a movable pipe 2 and a fixed pin 6, the left end of the movable pipe 2 is arranged inside the fixed pipe 1, the right end is arranged outside the fixed pipe 1, and the left end of the movable pipe 2 is provided with an annular plate 3. A spring I4 is provided between the annular plate 3 and the right wall 102 of the fixed pipe 1; a pin cap 61 is provided at one end of the fixed pin 6, and the end of the other end passes through the side wall 103 of the fixed pipe 1, and the fixed pin 6 is arranged between the annular plate 3 and the right wall 102 of the fixed pipe 1, the end of the fixed pin 6 passing through the fixed pipe 1 is a slope, the right end of the slope is flush with the inner wall of the fixed pipe 1, and the right end is arranged between the fixed pipe 1 and the fixed pipe 1. between active tube 2.

The spring I4 is a tension spring.

An elastic puller 9 is disposed between the annular plate 3 and the left wall 101 of the fixed pipe 1 .

A spring II7 is arranged between the pin cap 6 and the outer wall of the fixed pipe 1 .

The elastic constant of the elastic pull member 9 is smaller than that of the spring I4.

A sealing ring 5 is provided on the outer side of the annular plate 3 .

A washer 8 is arranged between the annular plate 3 and the right wall of the fixed pipe 1 .
