Abstract

An oscillating range adjusting module with modular design for being mounted into a sprinkler is revealed. The oscillating range adjusting module which includes a first adjusting unit and a second adjusting unit is located between a water-in control module and an oscillation driving module. During assembly, the first adjusting unit is fitted on an inlet tube of a water-in control module. After an O-ring being connected to the first adjusting unit, the second adjusting unit is mounted on the inlet tube and connected to the first adjusting unit by at least one fastener of the second adjusting unit engaged with at least one connection surface of the first adjusting unit. Lastly a water inlet of the oscillation driving module is connected to the second adjusting unit. Thereby, a modular assembly of the oscillating range adjusting module between the oscillation driving module and the water-in control module is achieved.

First claim

What is claimed is:

1. An oscillating range adjusting module of a sprinkler, adapted to be connected between a water-in control module and an oscillation driving module of the sprinkler, wherein an oscillation of a spraying nozzle module of the sprinkler is controlled by the oscillation driving module, the oscillating range adjusting module comprising:
a first adjusting unit comprising a first circular plate, a first circular side wall formed on a top surface of the first circular plate and a hollow connecting cylinder formed on a center of the first circular plate, wherein the first circular plate consisting of a first curved slot and a third curved slot provided therein, wherein the first curved slot is located beside the hollow connecting cylinder and close to the first circular side wall and the third curved slot is located beside the hollow connecting cylinder and close to the first circular side wall, wherein on an edge at a bottom of hollow connecting cylinder, a first connection surface is formed an located between the third curved slot and the hollow connecting cylinder and a second connection surface is formed and located between the first curved slot and the hollow connecting cylinder, wherein a limiting curved groove is formed on a bottom surface of the first circular plate, wherein a first pull member is connected to an outer surface of the first circular side wall and located beside the hollow connecting cylinder and opposite to the first curved slot; and
a second adjusting unit, configured to be connected to the first adjusting unit, comprising a second circular plate, a second circular side wall formed on a bottom surface of the second circular plate, a first insertion member, and a second insertion member, and having an assembly hole formed on a center of the second circular plate to be connected to the bottom of the hollow connecting cylinder of the first adjusting unit for forming a water inlet of the oscillation driving module of the sprinkler, wherein a first surface of the first circular plate, wherein the second circular plate consisting of a second curved slot and a fourth curved slot disposed thereon, wherein the second curved slot is located beside the assembly hole and close to the second circular side wall and the fourth curved slot is located beside the assembly hole and close to the second circular side wall, wherein the second circular plate further comprises a first snapping member and a second snapping member arranged at a top surface thereof and respectively engaged with the first connection surface and the second connection surface so as to connect the second adjusting unit to the first adjusting unit, wherein a limiting curved protrusion is formed on the top surface of the second circular plate to be mounted into the limiting curved groove of the first circular plate, wherein the first insertion member is formed on the top surface of the second circular plate and located between the fourth curved slot and the assembly hole and the second insertion member is formed on the top surface of the second circular plate and located between the second curved slot and the assembly hole, wherein the first insertion member and the second insertion member are arranged opposite to each other and respectfully inserted into the third curved slot and the first curved slot of the first adjusting unit when the second adjusting unit is connected to the first adjusting unit, wherein a second pull member is connected to an outer surface of the second circular side wall and located beside the assembly hole and opposite the second curved slot;
thereby when the first pull member is in contact with the second pull member, an intersection of the first curved slot of the first circular plate of the first adjusting unit and the second curved slot of the second circular plate of the second adjusting unit form a first limiting slot for limiting the spraying nozzle module to swing within a minimum oscillating range for limiting a swing limiting member of the oscillation driving module to swing in the first limiting slot, and that by pulling one of the first pull member and the second pull member to set a maximum distance therebetween, an intersection of the first curved slot of the first circular plate of the first adjusting unit and the second curved slot of the second circular plate of the second adjusting unit form a second limiting slot for limiting the spraying nozzle module to swing within a maximum oscillating range, so that a swing limiting member of the oscillation driving module of the sprinkler is able to be limited to swing in the second limiting slot while the oscillation driving module controlling a swing of the spraying nozzle module.

2. The oscillation range adjusting module, as recited in claim 1 , further comprising an O-ring being clipped between the bottom of the hollow connecting cylinder of the first adjusting unit and an edge of the assembly hole of the second adjusting unit when the top surface of the second circular plate is connected to the bottom surface of the first circular plate and the limiting curved protrusion is inserted into the limiting curved groove.

3. The oscillating range adjusting module, as recited in claim 2 , further comprising a first pull member connected to an outer surface of the first circular side wall and located beside the hollow connecting cylinder and opposite to the first curved slot, a second pull member connected to an outer surface of the second circular side wall and located beside the assembly hole and opposite to the second curved slot.

4. The oscillating range adjusting module, as recited in claim 3 , wherein a surface of the first circular plate is defined as a top surface for facing a water-in control module of the sprinkler while a surface of the second circular plate is defined as a bottom surface for facing the oscillation driving module.

5. The oscillating range adjusting module, as recited in claim 4 , wherein the first pull member comprises a first base portion and a first pull portion for being pulled while a bottom surface of the first base portion is in close contact with the outer surface of the second circular side wall, wherein the second pull member comprises a second base portion and a second pull portion for being pulled while a bottom surface of the second base portion is in close contact with the outer surface of the first circular side wall, wherein the first limiting slot is formed when the first base portion of the second pull member is in contact with the second base portion of the second pull member.

6. The oscillating range adjusting module, as recited in claim 3 , wherein a surface of the second circular plate is defined as a top surface for facing a water-in control module of the sprinkler while a surface of the first circular plate is defined as a bottom surface for facing the oscillation driving module.

7. The oscillating range adjusting module, as recited in claim 6 , wherein the first pull member comprises a first base portion and a first pull portion for being pulled while a bottom surface of the first base portion is in close contact with the outer surface of the second circular side wall, wherein the second pull member comprises a second base portion and a second pull portion for being pulled while a bottom surface of the second base portion is in close contact with the outer surface of the first circular side wall, wherein the first limiting slot is formed when the first base portion of the second pull member is in contact with the second base portion of the second pull member.

8. The oscillating range adjusting module, as recited in claim 3 , wherein the first pull member comprises a first base portion and a first pull portion for being pulled while a bottom surface of the first base
