[0001] The utility model relates to an interior wall painting device, in particular to an interior wall painting device for construction engineering, which is applied in the field of construction engineering. Background Art

[0002] When constructing and renovating building walls, they usually need to be painted with corresponding painting tools. The roller brush body with a long-handled grip can facilitate the rapid painting of large-area walls and high places. The painted walls can help improve the aesthetics of the building and make the walls more durable.

[0003] The specification of Chinese patent CN217734728U discloses a wall brushing roller device. The utility model drives the second threaded rod to rotate when the out-of-phase motor runs. The rotation of the second threaded rod drives the first transmission wheel to rotate. The rotation of the first transmission wheel drives the second transmission wheel to rotate using the transmission belt. The rotation of the second transmission wheel drives the first threaded rod to rotate. When the second threaded rod and the first threaded rod rotate, the dye flows into the roller from the material guide groove and finally flows into the dye cloth from the guide hole in the roller. After the dye cloth is soaked with the dye, the user drives the dye cloth to brush the wall through the round rod, so that it can be automatically stained with the dye, saving time and effort.

[0004] However, in actual application, when the paint is automatically fed into the dye cloth through an external component, the amount of paint cannot be controlled, and the surface of the dye cloth may be stained with too much paint, which will not only cause uneven painting of the wall, but the excess paint will also drip down along the dye cloth, thereby reducing the painting efficiency and causing paint waste. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when paint is automatically fed in directly through an external component, the amount of paint cannot be controlled, which may cause the surface of the dye cloth to be stained with too much paint, which will not only cause uneven wall painting, but also the excess paint will drip down along the dye cloth.

[0006] In order to solve the above problems, the utility model provides an interior wall painting device for construction engineering, including a cart, a liquid pump and a containing box are fixedly connected to the upper end of the cart, a liquid inlet pipe is fixedly connected between the liquid inlet of the liquid pump and the containing box, a liquid outlet of the liquid pump is fixedly connected to a liquid outlet hose, an end of the liquid outlet hose away from the liquid pump is fixedly connected to a liquid storage box, a support pipe is fixedly connected to the lower end of the liquid storage box, a controller is fixedly installed on the outer surface of the support pipe, a push plate is provided on the inner bottom wall of the liquid storage box, a piston sleeve is fixedly provided on the outer annular surface of the push plate, and the piston sleeve is fixedly provided on the outer annular surface of the push plate. The outer surface of the sleeve fits with the inner wall of the liquid storage box, the outer surface of the support tube is cut with a slide groove, the lower end of the push plate is fixedly connected to a push rod, the end of the push rod away from the push plate moves in sequence through the liquid storage box and the slide groove, the upper end of the liquid storage box is fixedly connected to a mounting tube, the end of the mounting tube away from the liquid storage box is fixedly connected to a brush assembly, the brush assembly includes a horizontal tube and a positioning sleeve fixedly mounted on the outer surface of the horizontal tube, the left end of the positioning sleeve is rotatably connected to a discharge pipe, the outer surface of the discharge pipe is cut with a plurality of discharge grooves, and the outer surface of the discharge pipe is fixedly provided with a roller brush.

[0007] In the above-mentioned interior wall painting device for construction engineering, the paint can be pumped into the liquid storage box, and the paint can be manually sent into the roller brush through the push rod, and the amount of paint can be manually controlled, thereby effectively preventing the roller brush from being stained with excessive paint, which is convenient for the staff to use.

[0008] As a further improvement of the present application, a motor is fixedly connected to the lower end of the cart, and an output end of the motor passes through the cart and the containing box in sequence and is fixedly connected to a stirring rod.

[0009] As a further improvement of the present application, an electric valve is fixedly installed at one end of the liquid outlet hose close to the liquid storage box, and the liquid pump and the electric valve are both connected to the controller signal.

[0010] As a further improvement of the present application, the front end of the liquid storage box is fixedly inlaid with glass, and a handle is fixedly sleeved on the outer surface of the push rod near one end of the support tube.

DETAILED DESCRIPTION

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1 and Figure 2Shown: an interior wall painting device for construction engineering, including a cart 1, a liquid pump 2 and a containing box 3 are fixedly connected at the upper end of the cart 1, and technicians in this field can select a suitable type of liquid pump 2 according to actual needs, for example: XBD7.6 / 5W, a liquid inlet pipe is fixedly connected between the liquid inlet of the liquid pump 2 and the containing box 3, a liquid outlet hose 4 is fixedly connected to the liquid outlet of the liquid pump 2, and a liquid storage box 5 is fixedly connected to the end of the liquid outlet hose 4 away from the liquid pump 2, and the liquid storage box 5 can temporarily store paint, and the lower end of the liquid storage box 5 is fixedly connected to a support tube 6, which is convenient for workers to take and paint, and a controller 16 is fixedly installed on the outer surface of the support tube 6, and technicians in this field can select a suitable type of controller 16 according to actual needs, for example: OHR-B300A-A The controller 16 can control the motor 17, the electric valve and the liquid pump 2. The motor 17 is fixedly connected to the lower end of the cart 1. Those skilled in the art can select a suitable type of motor 17 according to actual needs, for example: Y2-63M1-2-0.18KW. The output end of the motor 17 passes through the cart 1 and the containing box 3 in sequence and is fixedly connected with a stirring rod 18. The stirring rod 18 can be driven to rotate by starting the motor 17, so as to continuously stir the paint in the containing box 3, and effectively prevent the paint from settling in the containing box 3. An electric valve is fixedly installed at one end of the liquid outlet hose 4 close to the liquid storage box 5. Those skilled in the art can select a suitable type of electric valve according to actual needs, for example: D341X-10C. The liquid pump 2 and the electric valve are both connected to the controller 16 signal.

[0025] Figure 3 , Figure 4 and Figure 5It is shown that: a push plate 19 is provided on the inner bottom wall of the liquid storage box 5, and a piston sleeve 7 is fixedly sleeved on the outer annular surface of the push plate 19. The outer surface of the piston sleeve 7 fits with the inner wall of the liquid storage box 5, so that the paint accumulates on the top of the push plate 19. A slide groove 8 is cut on the outer surface of the support tube 6. The slide groove 8 facilitates the up and down movement of the push rod 9. The lower end of the push plate 19 is fixedly connected to a push rod 9. The end of the push rod 9 away from the push plate 19 moves through the liquid storage box 5 and the slide groove 8 in turn. The staff can manually push the push rod 9 to move the push plate 19 upward, thereby pushing the paint out of the liquid storage box 5. The upper end of the liquid storage box 5 is fixedly connected to a mounting tube 10, and the end of the mounting tube 10 away from the liquid storage box 5 is fixedly connected to a paint brush assembly. The brush assembly includes a transverse tube 11 and a positioning sleeve 12 fixedly mounted on the outer surface of the transverse tube 11. The left end of the positioning sleeve 12 is rotatably connected to a discharge tube 13. The positioning sleeve 12 can support and limit the discharge tube 13. A plurality of discharge slots 14 are cut on the outer surface of the discharge tube 13. Paint overflows through the discharge slots 14, thereby staining the roller brush 15 with paint. A roller brush 15 is fixedly mounted on the outer surface of the discharge tube 13. Glass is fixedly inlaid on the front end of the liquid storage box 5. A handle is fixedly mounted on one end of the outer surface of the push rod 9 close to the support tube 6. The handle is convenient for the staff to hold the push rod 9. The discharge slot 14 is arc-shaped, and a plurality of discharge slots 14 are distributed in a circular array around the central axis of the discharge tube 13.

[0026] When in use, pour the paint into the storage box 3, and pump it into the liquid storage box 5 through the liquid pump 2 for temporary storage. When painting the wall, push the push rod 9 upward to move the push plate 19 upward, thereby pushing the paint in the liquid storage box 5 upward, so that the paint enters the horizontal pipe 11 and the discharge pipe 13 through the installation pipe 10, and then overflows through the multiple discharge slots 14, so that the roller brush 15 is stained with paint from the inside to the outside, and then the wall is painted, so that the staff can manually control the amount of paint, effectively avoid excessive paint delivery, and cause the paint on the surface of the roller brush 15 to drip, so as to facilitate uniform painting of the wall and improve the painting efficiency.

[0027] The second implementation method:

[0028] Based on the first embodiment, this embodiment adds a painting component, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 6 It is shown that there are two painting components, and the two roller brushes 15 are distributed in parallel up and down. One of the roller brushes 15 is a long-haired brush barrel, and the other roller brush 15 is a short-haired brush barrel. The long-haired brush barrel can dip a large amount of paint and can paint a larger area, but the knurling is larger, which will produce fine textures. The short-haired brush barrel absorbs relatively less paint, and the paint surface after painting is more uniform. First use the long-haired brush barrel to paint a large area, and then use the short-haired brush barrel for a second brushing. This can effectively save paint and improve the uniformity and smoothness of the wall.

[0030] When in use, two roller brushes 15 are used simultaneously to paint the wall, so that the wall is first painted by the long-haired brush barrel and then by the short-haired brush barrel, thereby improving the painting efficiency of the wall and the painted wall is more uniform and smooth.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
