Technical Field

[0001] The utility model relates to the technical field of building painting tools, in particular to a painting roller for anti-seepage construction of building exterior walls. Background Art

[0002] During the construction of the walls of a building, in order to prevent rainwater from penetrating the walls and causing damage to the building, anti-seepage paint will be applied to the exterior walls. When applying paint to the exterior walls, a paint roller is often used. The paint roller is also called a roller brush, which is divided into three types: long hair, medium hair, and short hair. It is a tool used for applying paint over large areas.

[0003] However, when painting walls, the existing roller brush needs to be continuously dipped into the paint bucket before painting, which not only wastes time and seriously reduces work efficiency, but also causes a large amount of paint to drip during the process of taking the roller brush out of the paint bucket and painting on the wall, which causes a lot of paint to be wasted.

[0004] To this end, we provide a paint roller for anti-seepage construction of building exterior walls to solve the above problems. Utility Model Content

[0005] 1) Technical problems solved

[0006] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a painting roller for anti-seepage construction of building exterior walls.

[0007] 2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a painting roller for anti-seepage construction of building exterior walls, comprising a roller, a roller brush being clamped at the outer end of the roller, a connecting head being connected to the side end of the roller, a bent pipe being fixedly connected to the side end of the connecting head, a detector being fixedly connected to the side end of the bent pipe, a tube being fixedly connected to the lower end of the bent pipe, and a handle being fixedly connected to the lower end of the tube.

[0015] 3) Beneficial effects

[0016] Compared with the existing technology, the coating roller for anti-seepage construction of building exterior walls has the following beneficial effects:

[0017] 1. The utility model has a paint hole in the rotating roller and a discharge hole in the roller brush, and the paint is injected into the tube by a suction pump, and then the paint is pushed by a telescopic cylinder, so that the paint can be directly overflowed from the rotating roller to the surface of the roller brush, so that the staff does not need to dip the paint, which saves the time of dipping the roller brush in the paint, can facilitate painting, improve work efficiency, and effectively reduce the amount of paint dripping. It solves the problem that the existing roller brush needs to constantly dip the paint in the paint bucket before painting when painting the wall, which not only wastes time and seriously reduces work efficiency, but also a large amount of paint will drip in the process of taking the roller brush out of the paint bucket and painting on the wall, which will cause a lot of paint to be wasted.

[0018] 2. The utility model can facilitate the replacement of the roller brush by sleeve-connecting the roller brush to the outer end of the rotating roller. Specifically, when replacing the roller brush, one hand holds the roller brush to prevent it from moving, and the other hand rotates the rotating handle to remove the threaded rod from the threaded groove, so that the push shell releases the fixation of the roller brush, and the roller brush can be removed. Then, a new roller brush is sleeved on the outer end of the rotating roller, and the threaded rod is inserted into the threaded groove. The rotating handle is rotated in the opposite direction, and the threaded rod cooperates with the threaded groove to drive the push shell to gradually clamp the roller brush, thereby completing the replacement.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1-6 As shown, the utility model provides a technical solution: a paint roller for anti-seepage construction of building exterior walls, comprising a roller 1, which is in the shape of an octagonal prism and hollow inside. A roller brush 2 is clamped on the outer end of the roller 1, and an octagonal groove is provided on the inner wall of the roller brush 2, so that the roller brush 2 is sleeved on the outer end of the roller 1 to avoid relative sliding between the two. A paint hole 101 is provided on the outer end surface of the roller 1, and a discharge hole 201 is provided inside the roller brush 2. The paint hole 101 is aligned with the discharge hole 201 and is connected to the paint hole 101, so that the paint in the roller 1 can be discharged to the surface of the roller brush 2 through the paint hole 101 and the discharge hole 201. The apertures of the paint hole 101 and the discharge hole 201 are small, and the paint is relatively viscous, so that the paint is difficult to overflow without external force. A baffle 102 is fixedly connected to the side end of the roller 1, and the baffle 102 is used to constrain the position of the roller brush 2.

[0028] A threaded groove 103 is provided at the side end of the roller 1, and the threaded groove 103 does not pass through the roller 1. A threaded rod 8 is connected to the inner thread of the threaded groove 103, and a push shell 9 is provided at the outer end of the threaded rod 8. The push shell 9 is clamped with the side end of the roller brush 2. The side end of the threaded rod 8 is fixedly connected with a rotating handle 10, and the rotating handle 10 can facilitate the rotation of the threaded rod 8. The rotation of the threaded rod 8 cooperates with the threaded groove 103, so that the threaded rod 8 can move in the threaded groove 103, thereby driving the push shell 9 to move. The push shell 9 cooperates with the baffle 102 to clamp and lock the roller brush 2. Reverse rotation of the threaded rod 8 can release the push shell 9 from fixing the roller brush 2, so that the roller brush 2 can be replaced.

[0029] The side end of the roller 1 is connected to a connector 3, which can make the roller 1 rotate. The two are tightly connected to prevent the paint from overflowing from the connection gap between the two. The side end of the connector 3 is fixedly connected to a bend pipe 4, and the lower end of the bend pipe 4 is fixedly connected to a tube 6. The bend pipe 4 is a hollow tube and is connected to the roller 1 and the tube 6, so that the paint can enter the roller 1 from the tube 6 through the bend pipe 4. The outer end of the tube 6 is provided with a paint hose 11, and the tail end of the paint hose 11 is provided with a suction pump 12. The suction pump 12 is placed in the paint bucket to extract the paint into the tube 6. A filter plate is provided at the feed port of the suction pump 12 to prevent unmixed granular paint from entering the device and causing blockage.

[0030] The lower end of the tube 6 is fixedly connected to a handle 7, and a telescopic cylinder 13 is fixedly connected to the inside of the handle 7. A button is provided on the handle 7 to start the telescopic cylinder 13. The driving end of the telescopic cylinder 13 is movably connected to the tube 6. The driving end of the telescopic cylinder 13 is fixedly connected to an extrusion plate 14, and the extrusion plate 14 is slidably connected to the tube 6. Starting the telescopic cylinder 13 to push the extrusion plate 14 can squeeze the paint in the tube 6 into the roller 1. The paint in the roller 1 is squeezed and will overflow through the paint hole 101.

[0031] The side end of the bent pipe 4 is fixedly connected to a detector 5, which is used to detect the amount of paint in the roller 1. When the inside of the roller is full of paint, the detector 5 will be pressurized to generate a signal, which can stop the pump 12. A movable plate 501 is slidably connected to the inside of the detector 5, and a pressing head 502 is fixedly connected to the rear end of the movable plate 501. A contact head 503 is provided in the detector 5, and a spring 504 is fixedly connected to the rear end of the movable plate 501. The spring 504 is fixedly connected to the inside of the detector 5. The elasticity of the spring 504 is very small. The force applied to the spring 504 when it is compressed and retracted is less than the force required for the paint in the roller 1 to overflow under pressure. The rear end of the contact head 503 A signal transmitter 505 is provided. When the feed pump 12 injects paint into the tube 6, the paint will enter the roller 1 through the bend 4. When the roller 1 is full of paint, the paint in the bend 4 will have difficulty entering the roller 1, and it will squeeze the paint in the roller 1. At the same time, the paint in the bend 4 will push the movable plate 501. The movable plate 501 will retract under pressure to make the pressing head 502 contact with the contact head 503. This will trigger the signal transmitter 505, and the signal transmitter 505 will send a signal to stop the feed pump 12, so as to avoid the situation where the paint continues to overflow from the roller 1 when the feed pump 12 injects paint into the tube 6.

[0032] Working principle: put the extraction pump 12 into the paint bucket, the extraction pump 12 extracts the paint and injects it into the tube 6 through the paint hose 11. When the tube 6 is full of paint, the paint will enter the roller 1 through the bend 4. When the roller 1 is full of paint, the paint in the bend 4 will find it difficult to enter the roller 1, which will squeeze the paint in the roller 1. At the same time, the paint in the bend 4 will push the movable plate 501. The spring 504 at the rear end of the movable plate 501 is compressed and retracted to make the pressing head 502 contact with the contact head 503, which can trigger the signal transmitter 505. The signal transmitter 505 sends a signal to stop the extraction pump 12.

[0033] Press the button on the handle 7 to start the telescopic cylinder 13 to push the extrusion plate 14. The extrusion plate 14 pushes the paint in the tube 6 and squeezes it into the elbow 4, thereby squeezing the paint in the roller 1, so that the paint in the roller 1 can overflow to the surface of the roller brush 2 through the paint hole 101 and the discharge hole 201, so that brushing can be carried out. When the telescopic cylinder 13 retracts, the paint in the tube 6 is squeezed out, and the remaining paint in the elbow 4 and the roller 1 will flow back, so that the detector 5 is no longer under pressure. The spring 504 rebounds and pushes the moving plate 501, so that the pressing head 502 is no longer connected to the contact head 503, and the signal transmitter 505 will send a signal to start the material pump 12 to inject paint into the tube 6 until the detector 5 is pressurized again and sends a signal to stop the material pump 12.
