Garden sprinkler adjustment structure

Abstract

A garden sprinkler adjustment structure includes: a base, a sprinkler unit, a displacement component, a nozzle strip, and a knob. The sprinkler unit has a sprinkler component and a cover that fit together. One side of the sprinkler component and the cover together form a mounting hole. Both sides of the mounting hole have elastic latches. A control plate extends from the center of one side of the displacement component. A through hole is passed through the control plate and connected to a spiral groove. The knob is provided with a ratchet gear and extends a shaft tube. The outer surface of the shaft tube has spiral patterns.

Claims

1. A garden sprinkler adjustment structure, comprising: a base, a sprinkler unit, a displacement component, a nozzle strip, and a knob, wherein: The base is equipped with a controller. One end of the controller has a water inlet for connecting to a water source, and the other end has a water outlet, allowing the base to connect to the sprinkler unit via the water outlet. The sprinkler unit has a sprinkler component and a cover that fit together. The sprinkler component is a hollow tubular shape with a connector at one end for connecting to the water outlet. The other end has an opening for inserting the nozzle strip into the sprinkler component. The nozzle strip is then pivotally connected to the base through an end cap installed on the opening. The sprinkler component has a recess and a spray surface arranged sequentially from top to bottom. The spray surface and the cover are respectively provided with a number of first and second through holes arranged along their axial direction. The length of these second through holes is gradually widened from the center of the cover to both ends. The recess is used to provide a space for the displacement component to be inserted and then closed by the closing of the cover. The center of one side of the sprinkler component and the cover together form a mounting hole. Both sides of the mounting hole have elastic latches. The top surface of the displacement component has multiple elongated adjustment holes that radiate outwards from the center to both ends. A control plate extends from the center of one side of the displacement component, and a sleeve hole runs through the control plate. The sleeve hole is connected to a spiral groove. When the displacement component is placed in the recessed part, the sleeve hole aligns with the mounting hole. The nozzle strip has a plurality of elastic nozzles protruding to match the number of the first through holes, allowing the nozzle strip to continuously pass through the first through hole, the adjustment elongated hole, and the second through hole inside the sprinkler component. The knob has a ratchet gear and an extended shaft tube. The outer surface of the shaft tube has a spiral pattern. The spiral pattern engages with the spiral groove, allowing the shaft tube to pass smoothly through the mounting hole and the sleeve hole. The rotation of the knob, via the spiral pattern, drives the displacement component to move horizontally. After rotation, the elastic pawl can also engage the ratchet gear, allowing the knob to be fully positioned.

2. The garden sprinkler adjustment structure as described in claim 1, wherein, The base is a frame.

3. The garden sprinkler adjustment structure as described in claim 1, wherein, The base is used to provide a shielding element for one end of the end cap that is pivotally connected to the end cap.

4. The garden sprinkler adjustment structure as described in claim 1, wherein, The water spray surface is provided with several guide rails, and the bottom surface of the displacement component is provided with several guide grooves. The guide grooves are used to provide the guide rails for insertion, so that the displacement component can be moved horizontally by the knob along a fixed path.

5. The garden sprinkler adjustment structure as described in claim 1, wherein, The cover is closed and then fastened to the sprinkler component.

6. The garden sprinkler adjustment structure as described in claim 1, wherein, The cover and the sprinkler unit are joined together with the mounting hole to clamp the knob, so that the knob can only be rotated on the sprinkler unit and cannot be pulled out.

7. The garden sprinkler adjustment structure as described in claim 1, wherein, The elastic nozzle is connected to the nozzle strip by a flange. By using the flange to fit into the first through hole, both leakage prevention and positioning effects can be achieved simultaneously.
