The quick-loading structure of the material tank of the paint spray gun

Abstract

The invention belongs to the technical field of a paint spray gun, and relates to a material tank fast mounting structure of a paint spray gun. The material tank fast mounting structure is characterized in that two sides, relative to an axial line, on the inner wall of the upper side of a first joint are respectively provided with short shafts or convex blocks transversely pointing at the axial line, two sections of arc-shaped grooves or bulges are axisymmetrically arranged on the outer wall of the lower side of a second joint, notches through which the short shafts or the convex blocks arranged on the first joint can pass via axial moving are formed in the end parts of the two sections of arc-shaped grooves or bulges, the short shafts or the convex blocks arranged on the first joint pass through the notches through axial moving, then rotate and can be clamped and connected onto the grooves or the bulges for realizing the fast connection of the first joint and the second joint, and a sealing ring is arranged between the first joint and the second joint. The material tank fast mounting structure has the advantages that the fast dismounting and mounting of the paint spray gun and the material tank can be realized by the first joint and the second joint, the production process is simple, the service life is long, the product maintenance is good, and the material tank fast mounting structure is applicable to the fast dismounting and mounting structure of various types of paint spray guns and material tanks.

Description

technical field [0001] The invention belongs to the technical field of paint spray guns, in particular to a quick-loading structure for a material tank of a paint spray gun. Background technique [0002] At present, there are two forms of connection between the tank of the paint spray gun and the paint spray gun: one is the threaded connection in the true sense; The material tank can be connected to the paint spray gun in less than a week after the butt joint of the threaded thread; its disadvantage is: for the threaded connection structure in the true sense, it must be rotated during disassembly (the paint tank is filled with paint during installation, and the weight large) material tank, so that the disassembly and assembly time of the material tank and the paint spray gun is long, and the labor intensity is high; for the screw connection structure of two arc-shaped threads, one is that the arc shape of less than one week is formed on the gun body of the paint spray gun. ...

[0002] At present, there are two forms of connection between the tank of the paint spray gun and the paint spray gun: one is the threaded connection in the true sense; The material tank can be connected to the paint spray gun in less than a week after the butt joint of the threaded thread; its disadvantage is: for the threaded connection structure in the true sense, it must be rotated during disassembly (the paint tank is filled with paint during installation, and the weight large) material tank, so that the disassembly and assembly time of the material tank and the paint spray gun is long, and the labor intensity is high; for the screw connection structure of two arc-shaped threads, one is that the arc shape of less than one week is formed on the gun body of the paint spray gun. The machining of threads is difficult and the production cost is high; the second is that the arc-shaped internal threads produced by turning are easy to be damaged due to cracks, bruises and other reasons due to poor strength, resulting in the scrapping of the entire paint spray gun
