Description

Plastic sprinkler {A plastic sprinkler}

The present invention has a mechanically coupled state when combining the sprinkler structure and the fixed body so that the coupling state can be clearly confirmed. The sprinkler structure is provided with a first rotor and a water crushing rotor to install water droplets into the secondary. It relates to a plastic sprinkler that can be crushed finely.

In general, the existing plastic sprinkler is the connection of the sprinkler structure and the water transfer pipe is mainly composed of a mechanical coupling using a screw or a frictional coupling of the surface.

That is, the conventional sprinkler is not only the productivity is reduced by making the female screw in the sprinkler structure of the coupling structure, but also takes a lot of time when disassembly and coupling because the male screw should be made to the fixture. In addition, when the sprinkler structure and the fixture are coupled by surface friction, the surface friction is required to be coupled, so that it is difficult to determine the reliable coupling state, and the water transfer pipe connected to the fixture in the coupled state is slightly elliptical. When the water is made of leaky structure.

In the conventional sprinkler structure structured as described above, screwing is not only productive but also inconvenient, such as when disassembly is required when urgent disassembly is required, such as when a nozzle is clogged. By friction, it is very difficult to know what kind of fastening state the fastening state is, so it requires excessive force for disassembly and assembly, but it is easy to break the joint. In addition, the existing sprinkler structure is not smooth where the shaft tube is attached to hold the shaft could not be used as an axis to rotate the droplet crushing rotor using it.

An object of the present invention is to solve the above problems, by having a mechanical coupling state when coupling the sprinkler structure and the fixed body so that the coupling state can be clearly confirmed by the first rotor and water droplets in the sprinkler structure It is an object of the present invention to provide a plastic sprinkler that can finely crush water droplets by installing a grinding rotor.

In order to achieve the above object, at least two compression bands are formed in the insertion tube of the fixed body, and the coupling tube of the sprinkler structure coupled to the nozzle is inserted into the inner side and the insertion tube is coupled to the lower side thereof. When the insertion tube is coupled, the compression band of the insertion tube is closely adhered to the inner surface of the coupling tube by the engagement of the locking projection and the locking jaw provided at the outside so that the water leaks even when the insertion tube is somewhat elliptical. The part to be made by the compression band is to be combined and disassembled with a minimum surface friction force.

In addition, the plastic sprinkler structure of the present invention can be used by combining the first rotor or the second rotor, and in some cases, additionally combines the droplet grinding rotor outside the rotating shaft of the first rotor and opens the through hole of the droplet grinding rotor. It is characterized by providing a coupling structure that can be used outside of the axial collection of the structure.

The crimping band 24 formed in the insertion tube 23 may have any shape such as trapezoid, semi-circle, triangle, and rectangle, and its height is 0.1 mm or more and width is 0.5 mm or more and the interval is 0.5 mm or more. do. In addition, the lower surface of the fixed body 20 is formed with a stopper 21a for preventing the hose 27 from being pulled out.

When the structure 10 and the fixing body 20 having the above-described configuration are coupled, the nozzle 30 having the injection pipe 31 is positioned above the insertion tube 23, and then the insertion tube 23 is inserted into the coupling tube 16 and the structure 10 is rotated 90 degrees. The locking protrusion 18 formed at the bottom of the coupling pipe 16 is caught by the locking step 25 of the fixing body 20.

The first rotor 40 and the droplet crushing rotor 50 coupled between the upper and lower side I beam rod-shaped apparatus bars 11 and 12 of the structure 10 are configured as follows.
