Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a portable multi-angle spraying device for building decoration and renovation. Background Technology

[0002] In building decoration and renovation projects, the application of paint (such as latex paint, wood paint, anti-corrosion paint, etc.) is one of the key processes. For the spraying of paint, spraying equipment is required, such as spray guns. The principle is that the paint is pressurized and atomized through a power system, and the atomized paint is evenly covered on the surface of various decorative substrates such as walls, ceilings, furniture, and pipes to form a continuous and smooth coating.

[0003] Existing spraying devices, such as spray guns, are simple in structure and operation, but the position of their nozzles is fixed. While this design method has high spraying efficiency, it is not very effective when dealing with complex or irregularly shaped parts or when frequent local touch-up spraying is required. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a portable multi-angle spraying device for building decoration and renovation to more accurately solve these issues.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a portable multi-angle spraying device for building decoration and renovation, including a gun body, a first connecting pipe connected to the output end of the gun body, and a flexible hose disposed on one side of the first connecting pipe and connected to the first connecting pipe through a sealing element. The other end of the flexible hose is connected to a second connecting pipe through a sealing element, and the other end of the second connecting pipe is threadedly connected to an atomizing cap. An arc-shaped transition plate is disposed on one side of the first connecting pipe and on both sides of the flexible hose. Connecting blocks are disposed above and below the first connecting pipe. A rotating disk is disposed on one side of the two connecting blocks. The rotating disk has a semi-circular rotating groove. A rotating block that matches the rotating groove is disposed on one side of the second connecting pipe. A screw is disposed on one side of the rotating block. A nut is threadedly connected to the screw. A scale strip is disposed on the rotating disk.

[0007] Furthermore, the sealing element includes a protruding end, a lip disposed on one side of the protruding end, and a spring clamp that is sleeved with the hose and used to fix the hose.

[0008] Furthermore, the second connecting pipe has an external thread on its outer surface and a barrier cover on its inner side, the barrier cover having an internal thread that mates with the external thread.

[0009] Furthermore, the present invention provides a raw material inlet on the gun body, which is connected to an external raw material injection device via a pipe. An air inlet is provided at the bottom of the gun body, which is connected to an external air source via a pipe. A cleaning fluid inlet is provided at the bottom of the gun body, on one side of the air inlet.

[0010] Furthermore, the gun body is provided with a trigger.

[0011] The beneficial effects of this utility model are:

[0012] The arrangement of the rotating disk, rotating block, screw and nut allows the operator to adjust the second connecting pipe and atomizing head at different angles according to the different spraying positions. The atomizing cap and second connecting pipe, which can be adjusted at different angles, have the advantages of high flexibility, adaptability to various complex shapes of workpieces, no spraying dead angles and wide applicability.

[0013] The curved transition plate allows the bends in the hose to transition in an arc shape during the bending process. The advantage of using an arc transition at the bend is that it can effectively disperse the stress at the bend and increase the service life of the hose itself. At the same time, it can also reduce the resistance of coatings and compressed gas during the flow process. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example

[0020] refer to Figure 1-3 A portable multi-angle spraying device for building decoration and renovation includes a gun body 1, a first connecting pipe 2 connected to the output end of the gun body 1, and a hose 4 disposed on one side of the first connecting pipe 2 and connected to the first connecting pipe 2 through a sealing element 3. The other end of the hose 4 is connected to a second connecting pipe 5 through the sealing element 3. The other end of the second connecting pipe 5 is threadedly connected to an atomizing cap 51. An arc-shaped transition plate 21 is disposed on one side of the first connecting pipe 2 and on both sides of the hose 4. Connecting blocks 22 are disposed above and below the first connecting pipe 2. A rotating disk 23 is disposed on one side of the two connecting blocks 22. A rotating groove 24 in a semi-circular shape is opened on the rotating disk 23. A rotating block 52 that cooperates with the rotating groove 24 is disposed on one side of the second connecting pipe 5. A screw 53 is disposed on one side of the rotating block 52. A nut 54 is threadedly connected to the screw 53. A scale strip 25 is disposed on the rotating disk 23.

[0021] The gun body 1 is designed to deliver the raw material to be sprayed into the first connecting pipe 2, and then through the first connecting pipe 2 to the hose 4 and the second connecting pipe 5, and finally through the atomizing cap 51 to atomize and spray it out, thus ensuring the coating spraying work is carried out.

[0022] The arrangement of the rotating disk 23, rotating block 52, screw 53 and nut 54 allows the operator to adjust the second connecting pipe 5 and atomizing head at different angles according to the different spraying positions. The atomizing cap 51 and the second connecting pipe 5, which can be adjusted at different angles, have the advantages of high flexibility, adaptability to various complex shapes of workpieces, no spraying dead angles and wide applicability.

[0023] The arc transition plate 21 can make the bend of the hose 4 bend in an arc shape during the bending process. The advantage of the arc transition at the bend of the hose 4 is that it can effectively disperse the stress at the bend of the pipe and increase the service life of the hose 4 itself. At the same time, it can also reduce the resistance of the coating and compressed gas during the flow process.

[0024] In this embodiment, the rotating groove 24 is configured to cooperate with the rotating block 52 and the screw 53, and provides a basis for the rotation of the rotating block 52 and the screw 53. The rotation range of the rotating groove 24 with respect to the rotating block 52 and the screw 53 is 180 degrees.

[0025] In this embodiment, the scale bar 25 provided on the rotating disk 23 can facilitate the staff to observe the rotation angle of the second connecting pipe 5, ensuring the accuracy of the angle adjustment of the second connecting pipe 5;

[0026] In this embodiment, the hose 4 can be an existing elastic recovery type pipe or a structurally reinforced pipe, such as a silicone tube or a metal corrugated pipe.

[0027] like Figure 2 As shown, the sealing element 3 includes a protruding end 31, a lip 32 disposed on one side of the protruding end 31, and a spring clamp 33 that is sleeved with the hose 4 and used to fix the hose 4.

[0028] The lip 32 is designed to form the first physical seal after being connected to the inner wall of the hose 4, while the elastic clamp can further fix the connection between the lip 32 and the hose 4, and simultaneously counteract the radial relaxation generated by the hose 4 during bending, maintaining the fitting pressure.

[0029] like Figure 2 As shown, the outer surface of the second connecting pipe 5 is provided with an external thread 55, and a barrier cover 6 is provided on the second connecting pipe 5. The inner side of the barrier cover 6 is provided with an internal thread that mates with the external thread 55.

[0030] The threaded connection between the external thread 55 and the internal thread makes it easy for workers to install the barrier cover 6 onto the second connecting pipe 5. The barrier cover 6 can block the paint from escaping during the paint spraying process by the atomizing cap 51 and prevent the paint from damaging the scale values ​​on the rotating disk 23.

[0031] In this embodiment, the gun body 1 is provided with a raw material inlet 11, which is connected to an external raw material injection device through a pipe. The bottom of the gun body 1 is provided with an air inlet 12, which is connected to an external air source through a pipe. The bottom of the gun body 1, and on one side of the air inlet 12, is provided with a cleaning fluid inlet 13.

[0032] In this embodiment, a trigger is provided on the gun body 1.

[0033] Working principle:

[0034] First, the staff removes the wall and connects the raw material feed and feed port to the external raw material injection equipment and air source through pipes. The raw material injection equipment injects the paint to be used into the gun body 1, and the compressed air output by the air source flows to the first connecting pipe 2, the hose 4 and the second connecting pipe 5, so that it is atomized and sprayed out through the atomizing cap 51. When the staff needs to adjust the angle of the atomizing cap 51, the nut 54 is loosened and the screw 53 is pulled at the same time, so that the screw 53 slides in the rotating groove 24. As the screw 53 slides, the angle of the atomizing cap 51 and the second connecting pipe 5 will change synchronously. After the angle of the atomizing cap 51 and the second connecting pipe 5 is adjusted, the staff can fix the adjusted atomizing cap 51 and the second connecting pipe 5 by tightening the nut 54.

[0035] A washer is provided between the nut 54 and the rotating disk 23.

[0036] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
