Description

Technical Field

[0001] This application relates to the field of rotating nozzles, and more particularly to a rotating water-spraying bird. Background Technology

[0002] A rotary sprinkler is an irrigation device that rotates automatically by water flow. It is widely used in gardens, lawns, agriculture, and sports fields. By evenly distributing water flow, it effectively improves irrigation efficiency and reduces water waste.

[0003] A rocker arm rotary sprinkler is an irrigation device that uses the impact of water flow to drive the rocker arm to swing, which in turn drives the nozzle to rotate. It is widely used in home gardens, lawns, agriculture, and commercial settings. When water flows out of the nozzle, the impact force pushes the rocker arm to swing. The swing of the rocker arm is converted into the rotational motion of the nozzle through a linkage mechanism, achieving fan-shaped or circular water spray coverage. When the rocker arm swings to its limit position, an internal torsion spring causes it to rebound, and the cycle continues.

[0004] However, during use, due to the constant and repeated swinging of the rocker arm, the connection strength between the torsion spring and other components is not high enough, which can easily cause the torsion spring to separate from other components and also cause damage to the torsion spring, making the rotary nozzle unusable. Utility Model Content

[0005] In order to extend the service life of the rotating nozzle, this application provides a rotating water spray bird.

[0006] The rotating water-spraying bird provided in this application adopts the following technical solution:

[0007] A rotating water-spraying bird includes a water spray pipe, a connector, a control post, a rocker arm, and a torsion spring. The connector includes a first connecting rod, a connecting plate, and a second connecting rod. The first and second connecting rods are respectively fixedly connected to both ends of the connecting plate. The ends of the first and second connecting rods away from the connecting plate are both fixedly connected to the outer wall of the water spray pipe. The connector and the water spray pipe together form a connection port. The control post is located inside the connection port and is rotatably connected to the outer wall of the water spray pipe around its own axis. The rocker arm passes through the connection port and is fixedly connected to the outer wall of the control post. The connecting plate has a limiting port, and the rocker arm has a positioning port. The torsion spring is sleeved on the outer periphery of the control post and passes through the limiting port and the positioning port. One end of the torsion spring is fixedly connected to the connecting plate, and the other end of the torsion spring is fixedly connected to the rocker arm.

[0008] By adopting the above technical solution, the limiting port and positioning port limit the torsion spring, so that the force at the connection between the two ends of the torsion spring is dispersed during use, the torsion spring is not easily damaged, and the service life of the rotating water spout is extended.

[0009] Preferably, the water spray pipe includes an inlet pipe, a first outlet pipe, and a second outlet pipe, which are interconnected. The first connecting rod is fixedly connected to the outer wall of the first outlet pipe, and the second connecting rod is fixedly connected to the outer wall of the second outlet pipe. The axis of the control column is collinear with the axis of the inlet pipe.

[0010] By adopting the above technical solution, it is easy to fix the connector to the water spray pipe. The first and second connecting rods are used to limit the swing of the rocker arm, which facilitates the automatic rotation of the nozzle.

[0011] Preferably, the water spray pipe further includes a support block, which is fixedly connected to the outer wall of the first water outlet pipe and the second water outlet pipe away from the water inlet pipe. The end of the support block away from the water inlet pipe is provided with a positioning groove, and one end of the control column is fixedly connected to a positioning column, which is coaxially rotatably embedded in the positioning groove.

[0012] By adopting the above technical solution, the positioning groove limits the rotation of the positioning column, so that the control column can rotate stably.

[0013] Preferably, the connecting plate has a through-hole, the through-hole is coaxially arranged with the positioning groove, and the end of the control column opposite to the water spray pipe is coaxially fixedly connected to a limiting column. The diameter of the limiting column is smaller than the diameter of the control column, and the limiting column is coaxially rotatably connected to the inner wall of the through-hole.

[0014] By adopting the above technical solution, the through-hole limits the rotation of the limiting post, and the connecting plate limits the rotation of the rotating post, so that the rotating post rotates stably within the connecting hole.

[0015] Preferably, the rocker arm includes a sleeve, a first rocker arm, and a second rocker arm. The sleeve is coaxially and fixedly connected to the outer wall of the control column. The first rocker arm and the second rocker arm are both fixedly connected to the outer wall of the sleeve. The first rocker arm and the second rocker arm are arranged opposite to each other. The first rocker arm is used to abut against the first connecting rod, and the second rocker arm is used to abut against the second connecting rod. The first rocker arm is used to be impacted by water sprayed from the first water outlet pipe. Both the first rocker arm and the second rocker arm are provided with positioning ports. The torsion spring is sleeved on the outer periphery of the sleeve.

[0016] By adopting the above technical solution, water sprayed from the first water outlet pipe impacts the first swing arm, causing the first swing arm to move away from the water outlet end of the first water outlet pipe. The rocker arm rotates, and the torsion spring causes the rocker arm to return to its original position. The second swing arm strikes the second connecting rod, causing the water spray pipe to rotate. After the first swing arm approaches the water outlet end of the first water outlet pipe, it is pushed away by the water flow. This continuous cycle causes the spray pipe to rotate.

[0017] Preferably, the rocker arm further includes an abutment block, which is fixedly connected to the outer wall of the sleeve and is disposed between the first rocker arm and the second rocker arm.

[0018] By adopting the above technical solution, the abutment block is used to abut the torsion spring, making the torsion spring less prone to deformation and damage, thus extending the service life of the rotating water spout.

[0019] Preferably, the end of the abutment block opposite to the sleeve is provided with an abutment groove, which is used to limit the torsion spring.

[0020] By adopting the above technical solution, the abutment groove limits the torsion spring, making the torsion spring less prone to damage and extending the service life of the rotating water spout.

[0021] Preferably, the connecting plate includes a fixing plate and a limiting plate. The first connecting rod and the second connecting rod are respectively fixedly connected to both ends of the fixing plate. The fixing plate has a placement annular groove coaxially provided at one end facing the water spray pipe. The limiting plate is fixedly connected to the bottom of the placement annular groove and has a limiting opening.

[0022] By adopting the above technical solution, it is easier for the torsion spring to pass through the limiting port.

[0023] Preferably, the connecting plate further includes a limiting block, which is fixedly connected to the groove wall of the placing annular groove, and the end of the limiting block facing away from the water spray pipe is used for the torsion spring to abut.

[0024] By adopting the above technical solution, the limiting block abuts against the torsion spring, making the torsion spring less susceptible to damage and extending the service life of the rotating water spout.

[0025] Preferably, the end of the limiting block opposite to the water spray pipe is provided with a limiting groove, which is used to limit the torsion spring.

[0026] By adopting the above technical solution, the limiting groove restricts the torsion spring, making the torsion spring less prone to damage and extending the service life of the rotating water spout.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The limiting port and positioning port limit the torsion spring, so that the force at the connection between the two ends of the torsion spring is distributed during use, the torsion spring is not easily damaged, and the service life of the rotating water spray bird is extended.

[0029] 2. Water sprayed from the first water outlet pipe impacts the first swing arm, causing the first swing arm to move away from the water outlet end of the first water outlet pipe. The rocker arm rotates, and the torsion spring causes the rocker arm to return to its original position. The second swing arm strikes the second connecting rod, causing the water spray pipe to rotate. After the first swing arm approaches the water outlet end of the first water outlet pipe, it is pushed away by the water flow. This cycle continues, causing the spray pipe to rotate.

[0030] 3. The limiting block abuts against the torsion spring, making the torsion spring less susceptible to damage and extending the service life of the rotating water spout. Attached Figure Description
