Abstract

The utility model relates to a watering device which is used for watering gardens in a moving mode. The watering device is composed of a water inlet pipe (1), a water outlet pipe (7), corresponding sealing rings (2) and (13), a main pipe body (3), a ball body (8), a connecting nut (6), a connecting rod and a rotating handle. The utility model is characterized in that a flow passage (9) with a big opening and a nozzle flow passage (10) are arranged on the water outlet pipe (7), and the water inlet pipe (1) of the watering device is connected to a hose which is connected with a pressure water source. The rotating handle rotates, the ball body (8) is driven by the connecting rod to rotate to corresponding positions, and functions of water flow of large flow quantity with low flow rate, water flow of small flow with high flow rate and cutting water flow can be realized during watering. Compared with a mode that water is directly sprinkled by rubber hoses, labor is saved, and appropriate water flow is easy to obtain.

Description

Watering device

The utility model relates to a kind of sprinkler, and it is made up of water inlet pipe and water outlet pipe, main pipe, spheroid, connecting rod, rotary handle, sealing ring and coupling nut.

At present, gardening moves to water and generally uses rubber hose.When the big flow of need, low speed water, it is still convenient to use; And when need watering flowers and trees at a distance, or foul, water outlet on the flushing flowers and trees road then need user's hand to pinch and press flexible pipe to export when wanting the low discharge high-velocity flow; When wouldn't water, then flexible pipe to be bent 180 ° backward, with the temporarily disconnected current.This mode had not only wasted time and energy, flow velocity but wayward suitably, and flexible pipe bending place cracky.

The purpose of this utility model is to avoid the deficiency of above-mentioned prior art, provide a kind of and can make things convenient for controlled water flow, by rotating rotary handle through the rotation of connecting rod drive spheroid, can make current flow velocity output and cut-out on demand, need not pinch the sprinkler of pressing and bending flexible pipe.

The utility model adopts connection structures such as water inlet pipe and water outlet pipe, main pipe, spheroid, coupling nut, connecting rod, rotary handle to form, and is characterized in that design has two outlet passages in outlet pipe.The built-in spheroid of main pipe is provided with passage, and this passage can make it by the rotation of rotary handle to cooperate with the outlet pipe runner.When the big flow low speed water of need, the spheroid passage promptly is screwed into the position that cooperates with big mouthful runner; When need low discharge high-velocity flow, the spheroid passage is cooperated with nozzle flow channel; In the time of wouldn't needing water, then spheroid passage water side can be screwed into outlet pipe two runner position intermediate, or make the spheroid channel vertical in the main pipe.By the relative position of rotation control spheroid passage and outlet pipe runner, the also flow velocity of fine-tuning water.Spheroid passage water inlet can be designed to the gradual shrinkage conical bore, to reduce resistance.For guaranteeing that outlet pipe two runner water inlet sealing rings do not come off, two runner water inlet borders are provided with groove, and sealing ring is embedded in wherein.The aperture of spheroid passage water side needs less than the minimum range D between the edge in the two runner water inlet sealing rings, can cut off current in the time of so just preventing two runners while spilling water and make it be in two outlet passage water inlet centre positions.

The utility model compared with the prior art, because of it designs big mouthful of runner and nozzle flow channel in outlet pipe, by rotating the relative position of rotary handle control spheroid passage and two runners, can obtain expediently to water required flow velocity and cut off current does not need the user to pinch to press and bending flexible pipe, convenient and strength-saving and flexible pipe cracky not.

The utility model Figure of description is as follows:

Fig. 1. the utility model front view.

Fig. 2. the utility model cutaway view of bowing.

The utility model embodiment will do as detailed below in conjunction with the accompanying drawings:

See Fig. 1 Fig. 2, this sprinkler is made up of the sealing ring (2) (13) and the coupling nut (6) of water inlet pipe (1), outlet pipe (7), main pipe (3), spheroid (8), connecting rod (4), rotary handle (5), different size.One end of connecting rod (4) is connected in the spheroid top, and the other end links to each other with rotary handle outside the main pipe.Water inlet pipe (1), outlet pipe (7) are one by two coupling nuts (6) with main pipe (3) connection structure.And water inlet pipe and water outlet pipe (1) (7) and spheroid (8), and main pipe (3) between, and between main pipe (3) and the connecting rod (4) corresponding sealing ring (2) is set, set sealing ring (13) in outlet pipe (7) two runner (9) (10) the water inlet border grooves, to realize the sealing of sprinkler.Outlet pipe is provided with two outlet passages, and one is big mouthful of runner (9), another is nozzle flow channel (10), and spheroid (8) is provided with passage and this passage water inlet (12) can be designed to the gradual shrinkage conical bore.The rotation control spheroid passage water side (11) by rotary handle (5) and the matching relationship of outlet pipe runner (9) (10) can be realized controlling flow velocity and be prevented the purpose of two runners spilling water and cut-out simultaneously.For guaranteeing the realization of aforementioned purpose, the aperture of spheroid passage water side (11) needs less than the minimum range D between the edge in outlet pipe two runners (9) (10) the water inlet sealing ring.

Claims

1, sprinkler, form by water inlet pipe (1), outlet pipe (7), main pipe (3), spheroid (8), connecting rod (4), rotary handle (5), sealing ring (2) (13) and coupling nut (6), it is characterized in that outlet pipe (7) is provided with two runners, one is a big mouthful of runner (9), and it two is nozzle flow channel (10).

2, sprinkler according to claim 1 is characterized in that outlet pipe (7) two runner (9) (10) water inlet borders are provided with groove, and sealing ring (13) is embedded in wherein.
