Technical Field

[0001] The utility model relates to the technical field of painting, in particular to a plastic handle with adjustable painting angle. Background Technique

[0002] Painting generally refers to a way of wall treatment in the construction industry, that is, using materials such as chalk, lime, coatings such as latex paint, paint, etc. to smear the wall to achieve the purpose of beautifying and protecting the wall. The roller brush, also known as the roller, is divided into three types: long hair, medium hair, and short hair. It is a tool for large-area paint rolling. The roller brush, which needs to be used with a paint tray, is the most labor-saving and time-saving brush because of its wide rolling surface. Especially after connecting the extension rod, it can easily paint the high places of the wall or the ceiling.

[0003] In the actual use of the existing painting roller, since the angle between the handle connected to it and the roller is fixed and cannot be adjusted, the roller can only roll and paint the wall at a single angle according to the position where the user stands. During the painting process, the user needs to frequently change the force application direction of the handle to paint the wall. When the wall is restricted by the terrain, the roller cannot rotate to change the rolling direction, making the actual use of the painting roller more cumbersome and the painting construction process more difficult. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that there is a disadvantage in the prior art that the painting rolling direction of the roller is inconvenient to adjust. For this reason, we propose a plastic handle with adjustable painting angle.

[0005] In order to achieve the above purpose, the present application adopts the following technical solution: a plastic handle with adjustable painting angle, including a plastic handle body. Both sides of one end of the plastic handle body are provided with chutes. The inner wall of the chute is slidably connected with a sliding plate. Both ends of one side of the sliding plate are fixedly connected with springs. The other end of the spring is fixedly connected with the inner wall of the chute. The bottom of the sliding plate is fixedly connected with an insertion plate. One end of the plastic handle body is rotatably connected with a semi-circular tooth plate through a rotating shaft. One side of the insertion plate is meshed with the surface of the semi-circular tooth plate. One side of the semi-circular tooth plate is fixedly connected with a housing. The inner wall of the housing is rotatably connected with a mounting plate. A painting roller is installed inside the mounting plate.

[0006] Preferably, through grooves are opened at both ends of the sliding plate. A sliding rod is fixedly connected to the inner wall of the chute. The surface of the sliding rod is slidably connected with the inner wall of the through groove.

[0007] Preferably, the sliding rod is arranged outside the spring, and the inner wall of the sliding rod is slidably connected with the surface of the spring.

[0008] Preferably, push rods are fixedly connected to both sides of the skateboard.

[0009] Preferably, one end of the plastic handle body rotates around the center of the radius of the semi-circular toothed plate.

[0010] Preferably, a plurality of circular grooves are formed at the top of the mounting plate. Both ends of the top of the housing are fixedly connected with nut plates. One end of the nut plate is threadedly connected with a threaded rod, and the bottom of the threaded rod is inserted into the inner wall of the circular groove.

[0011] Preferably, a fillet is formed at the opening at the top of the circular groove.

[0012] Technical effects and advantages of the present utility model:

[0013] In the present utility model, by the staff pushing down the skateboard to pull the spring to drive the plug board away from the semi-circular toothed plate, and then through the rotational connection between the plastic handle body and the semi-circular toothed plate, after rotating the plastic handle body to a specified position, releasing the skateboard to release the force generated by the spring, the spring rebounds to drive the skateboard to drive the plug board to move upward, so that the plug board is inserted on the surface of the semi-circular toothed plate, fixing the position of the plastic handle body, thereby adjusting the inclination angle between the plastic handle body and the housing, enabling the staff to adjust the inclination angle between the plastic handle body and the painting roller according to actual needs, so that the device can realize the angle adjustment of the plastic handle body, and realize the horizontal and vertical multi-angle painting operation of the plastic handle body.

These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Referring to Figure 1 - Figure 4 As shown, the present utility model provides a technical solution: a plastic handle with adjustable painting angle, including a plastic handle body 1. Both sides of one end of the plastic handle body 1 are provided with sliding grooves 2. The inner wall of the sliding groove 2 is slidably connected with a sliding plate 3. Both ends of one side of the sliding plate 3 are fixedly connected with springs 4, and the other ends of the springs 4 are fixedly connected with the inner wall of the sliding groove 2. The bottom of the sliding plate 3 is fixedly connected with an insertion plate 5. One end of the plastic handle body 1 is rotatably connected with a semi-circular toothed plate 6 through a rotating shaft. One side of the insertion plate 5 is meshed with the surface of the semi-circular toothed plate 6. One side of the semi-circular toothed plate 6 is fixedly connected with a sleeve 7. The inner wall of the sleeve 7 is rotatably connected with a mounting plate 8. A painting roller 9 is installed inside the mounting plate 8. By the staff pushing down the sliding plate 3 to pull the spring 4 to drive the insertion plate 5 away from the semi-circular toothed plate 6, and then through the rotational connection between the plastic handle body 1 and the semi-circular toothed plate 6, when the plastic handle body 1 is rotated to a specified position, the sliding plate 3 is released to release the force generated by the spring 4, so that the spring 4 rebounds to pull the sliding plate 3 to drive the insertion plate 5 to move upward, so that the insertion plate 5 is inserted on the surface of the semi-circular toothed plate 6, fixing the position of the plastic handle body 1, thereby adjusting the inclination angle between the plastic handle body 1 and the sleeve 7, enabling the staff to adjust the inclination angle between the plastic handle body 1 and the painting roller 9 according to actual needs, so that the device can realize the angle adjustment of the plastic handle body 1 and perform painting operations at multiple horizontal and vertical angles of the plastic handle body 1.

[0022] Referring to Figure 3 And Figure 4 As shown, in this implementation scheme: through grooves 10 are provided at both ends of the sliding plate 3. The inner wall of the sliding groove 2 is fixedly connected with sliding rods 11. The surface of the sliding rods 11 is slidably connected with the inner wall of the through grooves 10. Through the sliding connection between the through grooves 10 and the sliding rods 11, when the sliding plate 3 moves, the movement track of the sliding plate 3 can be restricted by the sliding rods 11, realizing the horizontal angle movement of the sliding plate 3, preventing the sliding plate 3 from tilting during movement, and making the insertion of the insertion plate 5 into the semi-circular toothed plate 6 more accurate.

[0023] Referring to Figure 3 And Figure 4 As shown, in this implementation scheme: the sliding rods 11 are arranged outside the springs 4, and the inner wall of the sliding rods 11 is slidably connected with the surface of the springs 4. When the springs 4 are storing energy and moving, through the setting that the sliding rods 11 are arranged outside the springs 4, when the springs 4 are stretched or rebounded, they are restricted by the sliding rods 11, preventing the springs 4 from curling inward and winding around each other, and restricting the movement track of the springs 4.

[0024] Refer to Figure 4 As shown, in this embodiment: Push rods 12 are fixedly connected to both sides of the skateboard 3. By arranging the push rods 12 on both sides of the skateboard 3, the staff can operate the push rods 12 to control the movement of the position of the skateboard 3, and the push rods 12 shield the surface of the semi-circular toothed plate 6 due to the arrangement of the push rods 12.

[0025] Refer to Figure 1 As shown, in this embodiment: One end of the plastic handle body 1 rotates around the center of the radius of the semi-circular toothed plate 6. By rotating around the radius of the plastic handle body 1 and the semi-circular toothed plate 6, the adjustment angle of the plastic handle body 1 can reach about 220°, realizing the vertical or horizontal angle use of the plastic handle body 1 and the painting roller 9, greatly improving the angle adjustability of the painting roller 9, and making the painting of the painting roller 9 more convenient.

[0026] Refer to Figure 5 As shown, in this embodiment: A number of circular grooves 13 are opened at the top of the mounting plate 8. Both ends of the top of the sleeve 7 are fixedly connected with nut plates 14. One end of the nut plate 14 is threadedly connected with a threaded rod 15. The bottom of the threaded rod 15 is inserted into the inner wall of the circular groove 13. By rotating the plastic handle body 1 to a specified angle and then rotating the sleeve 7 to adjust the angle between the plastic handle body 1 and the mounting plate 8, the threaded rod 15 is screwed into the circular groove 13 through the nut plate 14 to fix the inclined position of the mounting plate 8 and the plastic handle body 1, and adjust the angle between the plastic handle body 1 and the painting roller 9, so that the painting roller 9 is inclined with respect to the plastic handle body 1, realizing the diagonal painting of the painting roller 9, increasing the adjustability of the device, and realizing the flexible use of the plastic handle body 1.

[0027] Refer to Figure 5 As shown, in this embodiment: Fillets 16 are provided at the top opening of the circular groove 13. By providing the fillets 16 at the top opening of the circular groove 13, the top of the circular groove 13 is round and smooth. When the threaded rod 15 moves downward through the nut plate 14, due to the smooth design of the fillet 16, the threaded rod 15 can slide into the circular groove 13 when contacting the fillet 16, guiding the threaded rod 15 and making the insertion of the threaded rod 15 into the circular groove 13 more accurate and smooth.

[0028] Working principle: The staff pushes the skateboard 3 downward to pull the spring 4, driving the plug board 5 away from the semi-circular tooth plate 6. Then, through the rotational connection between the plastic handle body 1 and the semi-circular tooth plate 6, after rotating the plastic handle body 1 to the specified position, the skateboard 3 is released to let the force generated by the spring 4 rebound. The spring 4 rebounds to pull the skateboard 3, driving the plug board 5 to move upward, so that the plug board 5 is inserted on the surface of the semi-circular tooth plate 6, fixing the position of the plastic handle body 1, thereby adjusting the inclination angle between the plastic handle body 1 and the housing 7, enabling the staff to adjust the inclination angle between the plastic handle body 1 and the painting roller 9 according to actual needs, so that this device can realize the angle adjustment of the plastic handle body 1, and realize the painting operation of the plastic handle body 1 horizontally and vertically at multiple angles. Through the sliding connection between the through groove 10 and the slide bar 11, when the skateboard 3 moves, the movement track of the skateboard 3 can be restricted by the slide bar 11, realizing the horizontal angle movement of the skateboard 3, preventing the skateboard 3 from tilting during movement, making the insertion of the plug board 5 and the semi-circular tooth plate 6 more accurate. When the spring 4 moves for energy storage, due to the slide bar 11 being arranged outside the spring 4, when the spring 4 stretches or rebounds, it is restricted by the slide bar 11, preventing the spring 4 from rebounding inward and curling around each other. By restricting the movement track of the spring 4, through the push rods 12 arranged on both sides of the skateboard 3, the staff can operate the push rods 12 to control the movement of the skateboard 3, and the push rods 12 shield the surface of the semi-circular tooth plate 6 through the arrangement of the push rods 12. Rotating around the center of the radius of the plastic handle body 1 and the semi-circular tooth plate 6, the adjustment angle of the plastic handle body 1 can reach about 220°, realizing the vertical or horizontal angle use of the plastic handle body 1 and the painting roller 9, greatly improving the angle adjustability of the painting roller 9, making the painting of the painting roller 9 more convenient. By rotating the plastic handle body 1 to the specified angle and then rotating the housing 7 to adjust the angle between the plastic handle body 1 and the mounting plate 8, the threaded rod 15 is screwed into the round groove 13 through the nut plate 14 to fix the inclined position of the mounting plate 8 and the plastic handle body 1, adjusting the angle between the plastic handle body 1 and the painting roller 9, making the position of the painting roller 9 and the plastic handle body 1 inclined, realizing the diagonal painting of the painting roller 9, increasing the adjustability of the device, and realizing the flexible use of the plastic handle body 1. Through the rounded corner 16 opened at the top opening of the round groove 13, the top of the round groove 13 is round and smooth. When the threaded rod 15 moves downward through the nut plate 14, due to the smooth design of the rounded corner 16 of the threaded rod 15, the threaded rod 15 can slide into the round groove 13 through the rounded corner 16 when contacting the rounded corner 16, guiding the threaded rod 15, making the insertion of the threaded rod 15 and the round groove 13 more accurate and smooth.
