Description

Technical Field

[0001] This utility model relates to the field of pipe surface treatment technology, specifically a pipe surface painting device for building engineering. Background Technology

[0002] Pipe fittings are generally painted with anti-rust coating when they leave the factory using specialized painting equipment. However, at construction sites, some pipe fittings are not used in time and are piled up in one place for a long time. The anti-rust coating on the surface of the pipe fittings is easy to fall off, resulting in rust. When they are used again, the pipe fittings cannot be returned to the factory for painting. They are usually painted directly by workers using hand brushes, which is inefficient. In addition, the curved surface of the pipe fittings is not easy to paint. Utility Model Content

[0003] The purpose of this utility model is to provide a surface painting device for pipe fittings used in building engineering, so as to achieve rapid and uniform painting of the outer surface of the pipe fittings.

[0004] This utility model discloses a surface painting device for pipe fittings used in construction engineering, comprising a handle, a connecting rod, an outer ring, a nozzle, a material pipe, and a spraying device. The connecting rod is fixedly connected to the top surface of the handle, the outer ring is fixedly connected to the top surface of the connecting rod, the nozzle is fixedly connected to the inner wall of the outer ring, the nozzle of the nozzle faces the axis of the outer ring, the front end of the material pipe is fixedly connected to the nozzle inlet, and the spraying device includes a material tank and a spray pipe, with the rear end of the material pipe connected to the spray pipe of the spraying device.

[0005] Furthermore, the nozzle is provided in multiple parts, all of which are fixedly connected to the inner wall of the outer ring. The multiple nozzles are evenly distributed around the axis of the outer ring, and the nozzles of the multiple nozzles are all facing the axis of the outer ring. The front end of the material tube is connected to the inlet of the multiple nozzles.

[0006] Furthermore, the outer ring has an annular hollow cavity inside, and the front part of the material tube is embedded in the annular hollow cavity inside the outer ring in an annular shape. The inlets of multiple nozzles are all connected to the material tube embedded in the annular hollow cavity inside the outer ring in an annular shape.

[0007] Furthermore, it includes a connecting plate and a guiding mechanism. The guiding mechanism includes a fixed plate, a guide post, a sliding plate, a mounting base, a rotating shaft, a guide wheel, and a spring. One end of the connecting plate is fixedly connected to the end face of the outer ring. The fixed plate is fixedly connected to the end of the connecting plate away from the outer ring. The side wall of the fixed plate away from the connecting plate has a groove, and the groove is oriented in the same direction as the radius of the outer ring. The guide post is fixedly connected in the groove, and the guide post is oriented in the same direction as the radius of the outer ring. The sliding plate has a through hole at the rear, and the through hole at the rear of the sliding plate is slidably fitted into the guide post. The front of the sliding plate extends out of the groove. The top surface of the mounting base is fixedly connected to the bottom surface of the sliding plate extending out of the groove. The rotating shaft is rotatably connected to the lower end of the mounting base. The guide wheel is fixedly connected to the rotating shaft, and the guide wheel faces the axis of the outer ring. The spring is sleeved on the guide post, and the spring is located on the side of the guide post away from the axis of the outer ring. The upper end of the spring is connected to the top surface of the groove, and the upper end of the spring is connected to the top surface of the sliding plate.

[0009] Furthermore, two connecting plates are symmetrically connected to both the left and right end faces of the outer ring, with the two connecting plates on the left end face of the outer ring and the two connecting plates on the right end face of the outer ring being staggered.

[0010] Furthermore, the outer wall of the handle is provided with a pleated groove.

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

[0012] When using this utility model, the two sides of the pipe are raised, and the outer ring is put on the outside of the pipe. At this time, the guide wheel rotates on the outside of the pipe to ensure that the outer ring moves stably on the outside of the pipe and does not contact the pipe. The nozzle inside the outer ring achieves stable and uniform painting, ensuring the quality and efficiency of painting.

[0013] The guide column can push the sliding plate to move, and the sliding plate can drive the mounting base and the rotating shaft to move, which in turn drives the guide wheel to adjust to a certain extent.

[0018] like Figures 1-3 As shown, the present invention provides a surface painting device for pipe fittings used in construction engineering, comprising a handle 1, a connecting rod 2, an outer ring 3, a nozzle 6, a material pipe 7, and a spraying device 8.

[0019] Multiple nozzles 6 are provided, and all nozzles 6 are fixedly connected to the inner wall of the outer ring 3. The multiple nozzles 6 are evenly distributed around the axis of the outer ring 3, and the nozzles of the multiple nozzles 6 are all facing the axis of the outer ring 3. The front end of the material tube 7 is connected to the inlet of the multiple nozzles 6.

[0020] The outer ring 3 has an annular hollow inside, and the front part of the material pipe 7 is embedded in the annular hollow inside the outer ring 3 in a ring shape. The inlets of multiple nozzles 6 are all connected to the material pipe 7 embedded in the annular hollow inside the outer ring 3 in a ring shape.

[0021] When using this device, the power is turned on, the two sides of the pipe are raised, and the outer ring 3 is put on the outside of the pipe. At this time, the guide wheel 507 rotates on the outside of the pipe, which can ensure that the outer ring 3 moves stably on the outside of the pipe and will not contact the pipe. The nozzle 6 inside the outer ring 3 achieves stable and uniform painting, ensuring the quality and efficiency of painting. The spraying equipment 8 outputs the paint through the material pipe 7 and then discharges it through multiple nozzles 6.

[0022] This utility model includes a connecting plate 4 and a guiding mechanism 5. The guiding mechanism 5 includes a fixed plate 501, a guide post 503, a sliding plate 504, a mounting base 505, a rotating shaft 506, a guide wheel 507, and a spring 508. One end of the connecting plate 4 is fixedly connected to the end face of the outer ring 3. The fixed plate 501 is fixedly connected to the end of the connecting plate 4 away from the outer ring 3. A groove 502 is provided on the side wall of the fixed plate 501 away from the connecting plate 4. The groove 502 is oriented in the same direction as the radius of the outer ring 3. The guide post 503 is fixedly connected in the groove 502. The guide post 503 is oriented in the same direction as the radius of the outer ring 3. The sliding plate 506... 4. A through hole is provided at the rear. The sliding plate 504 is slidably sleeved in the guide post 503 through the rear through hole. The front of the sliding plate 504 extends out of the groove 502. The top surface of the mounting base 505 is fixedly connected to the bottom surface of the sliding plate 504 extending out of the groove 502. The rotating shaft 506 is rotatably connected to the lower end of the mounting base 505. The guide wheel 507 is fixedly connected to the rotating shaft 506. The guide wheel 507 faces the axis of the outer ring 3. The spring 508 is sleeved on the guide post 503. The spring 508 is located on the side of the guide post 503 away from the axis of the outer ring 3. The upper end of the spring 508 is connected to the top surface inside the groove 502. The upper end of the spring 508 is connected to the top surface of the sliding plate 504.

[0023] There are two connecting plates 4 connected to the end face of the outer ring 3. The two connecting plates 4 are symmetrical about the axis of the outer ring 3 at 180°. Each connecting plate 4 is connected to a guide mechanism 5, and the two guide mechanisms 5 are symmetrical.

[0024] Two connecting plates 4 are symmetrically connected to both the left and right ends of the outer ring 3. The two connecting plates 4 on the left end of the outer ring 3 and the two connecting plates 4 on the right end of the outer ring 3 are staggered.

[0025] The sliding plate 504 can drive the mounting base 505 and the rotating shaft 506 to move, which in turn drives the guide wheel 507 to adjust to a certain extent. At this time, it can be painted for pipes of different diameters to ensure work efficiency. Its spring 508 can squeeze the sliding plate 504 to slide stably on the outside of the guide post 503.

[0026] Generally, a connecting plate 4 and a guide mechanism 5 can be provided on one side of the outer ring 3. In use, the connecting plate 4 and the guide mechanism 5 are located in front of the outer ring 3 in the direction of movement, so that the outer ring 3 does not come into contact with the painted fittings.

[0027] The connection plate 4 and guide mechanism 5 on both sides of the outer ring 3 can improve the stability of the outer ring 3 sliding on the outside of the pipe fitting. However, it is inevitable that the guide wheel 507 located on the rear side of the movement direction of the outer ring 3 will come into contact with the painted pipe fitting, which can easily form scratches on the paint of the pipe fitting. However, since this utility model is generally used for washing and spraying anti-rust paint on building pipe fittings with peeling anti-rust paint, and the pipes are generally pre-buried during the later construction, the scratches on the paint will not affect the use of the pipe fitting later. If the scratches on the paint will affect the use of the pipe fitting, the technical solution of setting the connection plate 4 and guide mechanism 5 on one side of the outer ring 3 can be used.

[0028] The outer wall of handle 1 is provided with a pleated groove, which can increase friction and ensure a firm grip.
