Abstract
Description
Technical Field:
[0001] The utility model relates to a spraying gun with a rotatable and adjustable long rod, belonging to the technical field of spraying guns. Background Art:
[0002] The spraying gun is mainly used for spraying large areas and high-consumption thick coatings of high-viscosity coatings. The coating is transported to the spray gun through a high-pressure pipe under high pressure. When the coating is ejected from the nozzle, it is atomized. The coating is sucked in, sent to the nozzle, and the coating is pressed out of the nozzle and atomized under the pressure of up to 200 kg (20 MPa). This high pressure has an extremely fine atomizing effect on the coating. Since air is not used in this process, it is called the high-pressure airless process; this high-pressure spraying process has the advantages of extremely fine atomization, smokeless operation, and a smooth and bubble-free spraying surface. Similarly, it is worth mentioning that it also has the advantages of fast working speed and convenient operation.
[0003] Currently, the existing spraying guns cannot rotate and adjust the spraying angle. If the spraying direction needs to be adjusted, it requires cumbersome operations. When the working conditions are different, the direction of the nozzle needs to be rotated. If the nozzle only sprays in one direction, there will be unevenness. The products on the market all complete the change of the nozzle direction by the operator adjusting the arm direction, or adjusting the rotation direction of the nozzle (it needs to be loosened with a wrench and then rotated, and then tightened). The irrationality of the angle and posture makes it extremely laborious to operate and there are potential safety hazards. Content of the Utility Model:
[0004] In view of the above problems, the technical problem to be solved by the utility model is to provide a spraying gun with a rotatable and adjustable long rod.
[0005] A spraying gun with a rotatable and adjustable long rod of the utility model comprises a spraying gun, a rotatable device, an extension rod, a nozzle, and a duckbill seat. A rotatable device is screwed onto the paint outlet of the spraying gun. The rotatable device is composed of a connector and a rotation adjustment angle head. The connector is fixed on the paint outlet of the spraying gun. A rotation adjustment angle head is arranged outside the connecting column rod of the connector. A connecting cavity is arranged inside the rotation adjustment angle head. A gear positioning hole, a guiding positioning hole, a self-locking seal ring positioning groove, and a spraying center through hole are arranged on the inner wall of the connecting cavity. The lower end of the rotatable device is fixed with an extension rod. The spray gun guiding channel of the extension rod penetrates through the spraying center through hole. A nozzle is fixedly connected in front of the extension rod. A duckbill seat is connected to the outside of the nozzle.
[0006] Preferably, a gear hole, a guiding groove ring, a self-locking seal groove, and a self-locking seal slot are arranged on the connecting column rod of the connector. A gear ball is clamped on the gear hole. A first spring is arranged behind the gear ball. The gear ball and the first spring are arranged on the gear positioning hole of the rotation adjustment angle head. Half of the gear ball is arranged on the gear positioning hole.
[0007] Preferably, a guiding ball is clamped inside the guiding groove ring. A second spring is arranged behind the guiding ball. The guiding ball and the second spring are arranged in the guiding positioning hole of the rotary adjusting angle head, and half of the guiding ball is arranged on the guiding groove ring.
[0008] Preferably, a self-locking sealing O-ring is clamped inside the self-locking sealing groove and is arranged on the inner wall of the connection cavity of the rotary adjusting angle head. A self-locking sealing ring is clamped on the self-locking sealing groove and is clamped and fixed in the self-locking sealing ring positioning groove of the rotary adjusting angle head.
[0009] The beneficial effects of the utility model are as follows: It has a reasonable structural design, is simple to install and convenient to use. By installing a rotatable device on the spraying gun, without cumbersome operations, it solves the potential safety hazards existing when changing the spraying direction, can accurately position when adjusting the direction, the extension rod has a self-locking function, and the extension rod cannot be rotated during spraying, and is applied to high-pressure airless spraying.

Specific embodiments:
[0017] As Figures 1-5As shown in the figure, the present specific embodiment adopts the following technical solution: It includes a spraying gun 1, a rotatable device 2, an extension rod 3, a nozzle 4, and a duckbill seat 5. A rotatable device 2 is screwed onto the paint outlet of the spraying gun 1. The rotatable device 2 is composed of a connection head 21 and a rotation angle adjustment head 22. The connection head 21 is fixed to the paint outlet of the spraying gun 1. An outer connection column rod of the connection head 21 is provided with a rotation angle adjustment head 22. A connection cavity 221 is arranged inside the rotation angle adjustment head 22. On the inner wall of the connection cavity 221, there are a gear position positioning hole 222, a guiding positioning hole 223, a self-locking seal ring positioning groove 224, and a spraying center through hole 225. The lower end of the rotatable device 2 is fixed with an extension rod 3. The spray gun guiding channel of the extension rod 3 penetrates through the spraying center through hole 225. A nozzle 4 is connected and fixed in front of the extension rod 3. A duckbill seat 5 is connected to the outside of the nozzle 4. The duckbill seat 5 can play the role of guiding the spraying direction.
[0018] On the connection column rod of the connection head 21, there are a gear position hole 211, a guiding groove ring 212, a self-locking seal groove 213, and a self-locking seal slot 214. A gear position ball 23 is clamped on the gear position hole 211. A first spring 24 is arranged behind the gear position ball 23. The gear position ball 23 and the first spring 24 are arranged in the gear position positioning hole 222 of the rotation angle adjustment head 22. Half of the gear position ball 23 is arranged in the gear position positioning hole 222. This state can play the role of fixed limit. When the angle needs to be adjusted, the gear position ball 23 retracts into the gear position positioning hole 222 and rotates to the next one. Half of the gear position ball 23 is positioned on the gear position hole 211 for limit.
[0019] A guiding ball 25 is clamped in the guiding groove ring 212. A second spring 26 is arranged behind the guiding ball 25. The guiding ball 25 and the second spring 26 are arranged in the guiding positioning hole 223 of the rotation angle adjustment head 22. Half of the guiding ball 25 is arranged on the guiding groove ring 212. The guiding principle is completed by the rotation of the guiding ball 25 in the guiding groove ring 212.
[0020] A self-locking seal O-ring 27 is clamped in the self-locking seal groove 213 and is arranged on the inner wall of the connection cavity 221 of the rotation angle adjustment head 22. A self-locking seal ring 28 is clamped on the self-locking seal slot 214 and is clamped and fixed in the self-locking seal ring positioning groove 224 of the rotation angle adjustment head 22. When high-pressure paint enters the spraying channel, the self-locking seal O-ring 27 and the self-locking seal ring 28 are effectively locked by the reverse pressure to achieve the self-locking function.
[0021] Principle of the angle limit structure in this specific embodiment: Rotation drives the rotation of the rotation adjustment angle head 22. While the rotation adjustment angle head 22 drives the gear marbles 23 in the gear positioning holes 222 to rotate along the gear holes 211 on the connecting column rod of the connecting head 21, it also drives the directions of the extension rod 3 and the duckbill seat 5, adjusting to the spraying angle desired by oneself. With half of the gear marbles 23 fixed on the gear holes 211, rotation is limited when no one rotates it.
[0022] This specific embodiment is reasonably structured, simple to install, and convenient to use. By installing a rotatable device on the spray gun, without cumbersome operations, it solves the potential safety hazards existing when changing the spraying direction, can accurately position when adjusting the direction, the extension rod has a self-locking function, and the extension rod cannot be rotated during spraying, and it is applied to high-pressure airless spraying.
