Water gun

Abstract

The invention discloses a water gun. A joint is independently processed by adopting plastic, an annular convex edge is arranged at one end of the joint with a cylinder structure, after the joint is rotated and smelted through a rotary smelting machine, the annular convex edge is directly, integrally and hermetically connected with a water supply connecting port in the lower end of a gun handle, and then a soft plastic shell is connected with the gun handle, so that the problem of surface shrinkage caused by too thick wall of the plastic shell is solved, meanwhile the working reliability is also improved, and the water gun has the characteristic of simple structure, and can be used for reducing assembling components of the spraying water gun and lowering the production cost.

Description

【Technical field】 [0001] The invention relates to spraying equipment, especially a water gun. 【Background technique】 [0002] Usually, the gun body shell of the sprinkler gun and the joint used to connect the water supply pipe with the gun handle are generally integrally formed through a mold, and soft plastic materials are used. The holes should also be molded with corresponding screw teeth. Therefore, the plastic on the joint must have a thicker wall thickness. If the soft plastic is too thick, it will easily cause the surface of the plastic to shrink, which will affect the normal work and use, and also affect the performance of the spray gun. Appearance; In addition, when the joint is connected to the gun handle, an inner plug needs to be added to ensure the sealing of the connection. This structure increases the number of parts, which increases the process and cost. [0003] The present invention studies and proposes aiming at the deficiencies in the prior art. 【Conte...
