Background
A spray gun is a device that uses a quick release of liquid or compressed air as a motive force. The spray gun has wide application and can be directly used for filling paint. The existing spray gun comprises a gun body, a spray nozzle, an atomizing cap, a coating adjusting knob and the like. The coating adjusting knob is connected with the gun body through threads. In the daily spraying operation, an operator can control the paint flow of the spray gun by rotating the paint adjusting knob according to different spraying requirements.
In order to enable an operator to better master the degree of rotation of the paint adjustment knob. The manufacturer of the spray gun would print the range on the paint adjustment knob by laser. The measuring range is as shown in figure 1 of the specification attached figure of the spray gun disclosed in the Chinese invention patent No. CN103785563B, and the 0 scale of the measuring range is just aligned with the position of the die-closing seam of the gun body. Thus, the operator turns the paint adjustment knob to determine the paint flow rate of the spray gun.
The manufacturer then installs a paint adjust knob with range to the gun body. The paint adjustment knob is typically threaded onto the gun body. The internal threads of the paint adjusting knob are different in starting point or ending point after machining (different in actual machining), so that the directions corresponding to the range starting points on the paint adjusting knob of each spray gun are different after the paint adjusting knob is installed on the gun body and screwed. That is, when the paint adjusting knob is completely closed, the 0 scale of the range is not necessarily exactly aligned with the position of the mold clamping gap of the gun body, so that when an operator rotates the paint adjusting knob to the required flow, the actual flow of the spray gun deviates from the flow desired by the operator, which may affect the spraying operation.
