Paint gun structure

Abstract

The invention discloses a structure of a paint spray gun. The structure of the paint spray gun comprises a gun body, a connecting pipe, a paint receiving pipe, a gas pressure adjustment component and a spray nozzle component, wherein the gun body comprises a joint face, a flow channel and a paint receiving pipe orifice, wherein the joint face is provided with a connecting hole; the connecting pipe is connected into the connecting hole; the connecting pipe is provided with a fixed connecting hole and a connecting part; one end of the paint receiving pipe is provided with a connecting pipe end correspondingly penetrating into the fixed connecting hole of the connecting pipe; the paint receiving pipe is correspondingly connected to the paint receiving pipe orifice of the gun body; the gas pressure adjustment component is connected to the connecting pipe and comprises an adjustment ring body and a gas pressure ring, wherein the adjustment ring body is provided with a ring groove; the gas pressure ring is provided with a plurality of gas holes; the gas pressure ring is connected with the ring groove; and the spray nozzle component is combined with the gas pressure adjustment component, and is provided with a joint part connected with the connecting part. According to the paint spray gun disclosed by the invention, the gas pressure ring is replaced to be connected with the ring groove so as to adjust different gas pressure, and a user can conveniently disassemble the spray nozzle from the paint spray gun.

Description

technical field [0001] The invention relates to a paint spray tool, in particular to a paint spray gun structure. Background technique [0002] During the use of the paint spray gun, the pressure value of the sprayed gas needs to be adjusted frequently to match the use of different paint volumes. The user needs to disassemble the paint spray gun to achieve the purpose of adjusting the gas pressure. The conventional paint spray gun is like Figure 9 As shown, the paint spray gun includes a gun body A, an airflow guiding element B, an inner nozzle C, a splitter D and an outer nozzle E, wherein the inner nozzle C is screwed on the airflow guiding element B in the direction of positive teeth, and the airflow The guide element B is screwed on the gun body A in the opposite direction. [0003] Conventional paint spray guns have the following disadvantages: [0004] 1. When the conventional paint spray gun needs to replace the inner nozzle C with the airflow guiding element B, sin...

Problems solved by technology

[0004] 1. When the conventional paint spray gun needs to replace the inner nozzle C with the airflow guiding element B, since the inner nozzle C and the airflow guiding element B are in the state of positive and negative screw connection with each other, when the inner nozzle C rotates in the direction of the positive tooth on the airflow guiding When the component B is used, the inner nozzle C will also loosen the airflow guiding component B on the gun body A, and the user must rotate and fix the airflow guiding component B screwed on the gun body A again in the opposite direction. Therefore, every time the inner nozzle C is replaced, the airflow guiding element B must be adjusted on the gun body A, which is quite inconvenient to use

[0005] 2. Since the airflow guiding element B is integrally machined, and the airflow guiding element B is screwed to the external thread B1 of the gun body A, the turning process is complicated. If you want to adjust different air pressures and use it for painting, you need to replace the airflow guiding element B as a whole. It is relatively inconvenient for users to use, and the cost of manufacturing materials is relatively high

[0006] When dismantling the paint spray gun in the previous case, it is necessary to adjust the action of the airflow guiding element, and it is quite inconvenient to adjust the different gas pressures
