Embodiment

[0017] The conveniently adjustable paint spray gun of this embodiment is a manual air spray gun, and its structure is shown in Figure 1. The joint below the handle of the gun body 5 is used for external compressed air delivery pipelines, and the paint delivery pipeline joint under the gun body is connected to paint cans. . Compressed air passes through the nozzle at the gun head through the internal channel of the gun body from the handle. Since the paint can also passes through the nozzle at the gun head through the internal passage of the gun body, when the compressed air is input, the Venturi effect will be generated in the internal passage of the gun body above the paint can, and the paint liquid in the paint can will be sucked into the passage to make it It is mixed with compressed air and sprayed out from the center nozzle hole of the protruding nozzle 6 at the nozzle. The trigger mounted on the gun body 5 acts as a switch for controlling the on-off of the compressed ai...

Abstract

The present invention relates to one kind of easy-to-regulate paint spraying gun and belongs to the field of painting equipment technology. The paint spraying gun has a gun body, a joint with inner channel to the spout with central hole, a nozzle fixed to the tip of the gun, surrounded with an annular space and with distributed air jet holes, an annular baffle with at least two set of holes and set between the annular space and the nozzle, a clamp nut with notch, and a shifting rod to stretch out from the annular baffle and through the notch. When the shifting rod is located in the first position or the second position, the upper and lower jet holes or the left and the right jet holes are made to communicate without annular space. The easy-to-regulate paint spraying gun may be regulated fast in the spraying form so as to ensure the painting quality.

Description

technical field [0001] The invention relates to a spray gun, in particular to an improved structure of a spray gun for spraying paint, and belongs to the technical field of spraying equipment. Background technique [0002] Paint spray gun is a common tool in the spraying industry. Its typical structure is that the gun body is connected with gas and paint pipelines leading to the nozzle, the central spray hole at the nozzle is connected to the paint gas mixed flow channel, and the surrounding spray holes are connected to the air flow channel. When spraying, the compressed air carries the paint and sprays it from the central spray hole to make it atomized. The air sprayed from the surrounding spray holes not only further refines the paint mist, but more importantly, it can control the spray shape of the paint mist. For example, when only the air nozzles on the left and right sides of the center nozzle hole emit air, the paint mist sprayed from the center nozzle hole will form ...
