Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, in particular to a spray gun with an adjustable straw angle. Background Art

[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as power. Spray guns are divided into two types: ordinary pressure type and pressurized type. When the compressed air generated by an air compressor passes through the air cap at the front of the spray gun and is ejected, a low-pressure area lower than the atmospheric pressure is generated in front of the paint nozzle connected thereto. The spray gun is included in the automation selection of Kuaiyiyou. This pressure difference generated at the spray gun nozzle sucks the paint out of the paint storage tank and, under the action of the high-speed jet force of the compressed air, atomizes it into fine particles and sprays them on the surface of the object to be painted.

[0003] However, during the use of the spray gun, the paint kettle for storing the paint is often in an inclined state. At this time, the paint on the inner side wall of the paint kettle cannot be output, resulting in waste of the sprayed material. Therefore, it is necessary to provide a spray gun with an adjustable straw angle, so as to be able to output the remaining paint in the paint kettle. Summary of the Utility Model

[0004] In order to solve the problem that the paint on the inner side wall of the above-mentioned paint kettle is not easy to be ejected, the utility model provides a spray gun with an adjustable straw angle, and the specific technical solution is as follows:

[0005] A spray gun with an adjustable straw angle includes a spray gun head and a paint kettle installed at the spray gun head. The spray gun head includes a three-way joint pipe. A straw is arranged in the paint kettle. The top of the straw is communicated with the lower port of the three-way joint pipe. A connecting part is arranged below the spray gun head, and the paint kettle is communicated with the connecting part. The top of the straw is drivingly connected with an adjusting rotating pipe, and the adjusting rotating pipe is communicated with the straw. The lower port of the three-way joint pipe is communicated to the adjusting rotating pipe. An adjusting notch is arranged on the connecting part, and the adjusting rotating pipe is located at the adjusting notch. The lower end of the straw is provided with a bending part, and rotating the adjusting rotating pipe drives the bending part at the lower end of the straw to rotate in a direction.

[0006] In some embodiments, a claw is arranged at the top of the adjusting rotating pipe, and a clamping convex block is arranged at the lower port of the three-way joint pipe, and the claw and the clamping convex block are mutually engaged.

[0007] In some embodiments, a clamping notch is arranged on a part of the claw.

[0008] In some embodiments, a first sealing ring is sleeved on the three-way joint pipe, and the first sealing ring is located between the three-way joint pipe and the adjusting rotating pipe, and the first sealing ring seals the gap between the three-way joint pipe and the adjusting rotating pipe.

[0009] In some embodiments, a second sealing ring is provided on the straw, and the second sealing ring is located between the straw and the adjustable rotating tube, and the second sealing ring seals the gap between the straw and the adjustable rotating tube.

[0010] In some embodiments, a connecting cover that fits with the spray pot is provided at the lower end of the connecting portion, and a third sealing ring is provided on the straw. The third sealing ring is located between the straw and the connecting cover, and the third sealing ring seals the gap between the straw and the connecting cover.

[0011] In some embodiments, a rotating handle is provided on the adjusting rotating tube, and the rotating handle is fixedly connected to the adjusting rotating tube, and the adjusting rotating tube is rotated by turning the rotating handle.

[0012] In some embodiments, a recessed portion is disposed on the top of the straw, and a protrusion that fits with the recessed portion is disposed on the adjustable rotating tube.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] First, in the present invention, a bending portion is provided at the lower end of the straw, and the bending portion at the lower end of the straw is driven to rotate in a certain direction by rotating the adjusting tube. The lower end of the bending portion of the straw is located at the inner edge of the spray pot. The user can adjust the direction of the bending portion of the straw by rotating the adjusting tube, so that the bending portion of the straw can always be located at the lowest end of the liquid level in the spray pot at different angles of the spray gun.

[0015] Second, in this solution, a first sealing ring is arranged between the three-way pipe and the adjustable rotating pipe, and a second sealing ring is arranged between the straw and the adjustable rotating pipe. The first sealing ring and the second sealing ring can respectively seal the gap between the adjustable rotating pipe and the three-way pipe and the straw, thereby ensuring sufficient sealing when the straw rotates flexibly.

[0016] Thirdly, in this solution, a rotating handle is provided on the adjusting rotating tube, and the rotating handle is fixedly connected to the adjusting rotating tube. Turning the rotating handle drives the adjusting rotating tube to rotate, and the user can flexibly control the rotation of the adjusting rotating tube through the provided rotating handle.

[0017] Fourthly, a concave portion is arranged at the top of the straw, and a protrusion which matches with the concave portion is arranged on the adjustable rotating tube, so that the power transmission between the straw and the adjustable rotating tube can be satisfied through the mutually matching concave portion and protrusion.
