Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines and marking machines, in particular to an automatic spray gun. Background Art

[0002] Spraying machines and marking machines are equipped with spray gun components. When the spray gun is working, you need to press the start switch on the spray machine first. The internal conduction of the start switch forms a closed circuit to start the motor in the spray machine. Then pull the trigger on the spray gun to transport the pressurized paint from the supply hose to the spray gun and spray it out through the spray gun outlet.

[0003] Since the existing spray gun components need to press the start switch on the spray machine before working, in some occasions the spray gun is far away from the spray machine. The operator needs to hold the spray gun and drag the feed hose to walk back and forth between the spray machine and the spraying work surface to control the start and stop of the spray machine. The operation is inconvenient and it is easy for the spray machine feed pressure and speed to not match or the machine to stop frequently. It is extremely inconvenient and has potential safety hazards when working at high altitudes, resulting in slow operation speed and low efficiency, making it difficult to meet the needs of mass production. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an automatic spray gun, which utilizes a spray gun trigger for linkage operation, making the spray gun control more convenient and flexible, effectively improving work efficiency, and greatly improving work safety.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic spray gun comprises a spray gun body, a spray head, a gun handle, a trigger, a sheath and a touch-pressure switch, wherein the touch-pressure switch is arranged on the lower side of the gun handle, one end of the sheath is arranged between the spray gun body and the spray head, and the other end of the sheath is connected to the touch-pressure switch housing, the sheath surrounds the trigger, a compression spring paddle is arranged at the lower end of the sheath, the cantilever end of the compression spring paddle extends to above the button of the touch-pressure switch, and when the trigger is actuated, the tail end thereof presses the compression spring paddle to touch the button of the touch-pressure switch, thereby controlling the touch-pressure switch to form a closed loop.

[0007] Furthermore, the cable at the end of the touch-pressure switch is tied together with a feed hose connected to the rear end of the gun handle and connected to the sprayer.

[0008] Furthermore, a switch seat is provided on the lower side of the gun handle, and the touch-pressure switch is arranged on the gun handle through the switch seat.

[0009] Furthermore, the fixed end of the compression spring paddle is arranged on the housing of the touch-pressure switch, and the lower end of the sheath is riveted to the fixed end of the compression spring paddle.

[0010] Furthermore, the compression spring paddle is made of copper alloy.

[0011] Furthermore, a connecting thread is provided between the spray gun body and the spray head, and the upper end of the sheath is inserted into the connecting thread.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model utilizes the spray gun trigger for linkage operation. When the trigger is pulled, the touch pressure switch can be controlled to form a closed loop. The spray gun is more convenient and flexible to control, which can effectively improve work efficiency and greatly improve work safety.

[0014] 2. A compression spring paddle is added to the touch-pressure switch of the utility model, and the sheath is connected to the fixed end of the compression spring paddle, so that the compression spring paddle is firmly installed, the trigger linkage operation is reliable during use, and it is not easy to be triggered by mistake.
