Description

Technical Field

[0001] The utility model relates to the technical field of paintbrushes, in particular to a paintbrush with inclined bristles. Background Art

[0002] For the paintbrushes in the prior art, the front end face is generally flat, which can make the paint application more uniform, but it is not convenient to paint corners, arc surfaces and other places. Generally, when painting different surfaces, different sizes of paintbrushes are used for painting, and it is necessary to replace different sizes of paintbrushes, which increases the working intensity and is not convenient for workers to work.

[0003] The Chinese patent with the publication number CN208941168 U was proposed in the prior art to solve the above-mentioned existing technical problems. The technical solution disclosed in the patent document is as follows: a paintbrush with inclined bristles, including a brush handle, a brush head and bristles. The front end of the bristles is an inclined slope surface relative to the direction perpendicular to the brush handle. The thickness of the bristles gradually increases from one end of the inclined high surface to one end of the inclined bottom surface, so that the cross-section of the bristles is trapezoidal. The shape of the brush head is a three-dimensional isosceles trapezoid structure. A triangular plate surface is provided at the corner where the brush head is connected to the brush handle. The two sides of the brush handle are connected with brackets through bolt structures. The brackets can be rotated up and down for position adjustment. The brackets are composed of two side support plates and a cross plate. The width of part of the support plate is greater than the width of the triangular plate surface. The beneficial effects of the utility model are as follows: the bristles of the paintbrush of the utility model are inclined, meeting the painting requirements of the paintbrush for areas such as corners and arc surfaces; during the use of the paintbrush, it can prevent the paint from adhering to the hands. When not in use temporarily, it is convenient to place the paintbrush by adjusting the brackets. However, when using this device for painting, it does not have a high adaptability to corners at different angles, resulting in low painting efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a paintbrush with inclined bristles to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A paintbrush with inclined bristles includes a brush handle. A chute is provided on the brush handle, and a number of moving grooves are evenly arranged along the length direction of the chute inside the brush handle. A number of brush hairs are arranged inside the brush handle. One side of the brush hair is fixedly connected with a moving block, and the moving block is slidably connected with the moving groove. A baffle is fixedly connected inside the brush handle. One end of the brush hair close to the lead screw is fixedly connected with a compression spring, and the other end of the compression spring is fixedly connected with the baffle. A housing is fixedly connected inside the brush handle. A clockwork spring is arranged inside the housing. One end of the clockwork spring is fixedly connected with the housing, and the other end of the clockwork spring is fixedly connected with a moving belt. The moving belt is slidably connected with the housing. A support column is fixedly connected to the side of the brush handle far from the housing, and the moving belt is fixedly connected with the support column. A control component for changing the arrangement shape of the brush hairs is connected inside the brush handle, and a moving component for moving the brush hairs is connected inside the control component.

[0007] When it is necessary to paint the wall corners at different angles, the control component and the moving component can be adjusted to cooperate with each other to drive the moving belt to lift the brush hairs. At the same time, the moving belt will also act on the adjacent brush hairs. At this time, the compression spring is in a stretched state, so that a number of evenly arranged brush hairs can be combined into different shapes, so as to adapt to different angles for painting work. Such a setting not only enables the paintbrush to adapt to more wall corners at different angles, but also makes it more convenient to switch angles, thus improving the working efficiency of the device.

[0008] A further improvement of the technical solution of the present utility model lies in that: the control component includes a lead screw, the lead screw is rotatably connected with the brush handle, a first knob is arranged at one end of the lead screw, the first knob is fixedly connected with the lead screw, and a slider is threadedly connected to the lead screw. The slider is slidably connected with the brush handle.

[0009] Adopting the above technical solution, in this solution, when it is necessary to paint the wall corners at different angles, the first knob can be twisted to drive the lead screw fixedly connected thereto to rotate. The rotation of the lead screw will drive the slider slidably connected with the brush handle to move along the axis direction of the lead screw, so as to achieve the purpose of adjusting the position of the moving component.

[0010] A further improvement of the technical solution of the present utility model lies in that: the moving component includes a rotating shaft. A locking component for locking the position of the moving component is connected to the end of the rotating shaft far from the slider. The rotating shaft is rotatably connected with the slider. A bevel gear is fixedly connected to the end of the rotating shaft close to the slider. A shaft body is rotatably connected inside the slider. A bevel gear and a gear are fixedly connected to the shaft body. The bevel gears are meshed with each other. A rack is arranged below the gear. The gear is meshed with the rack. The rack is slidably connected with the slider. One end of the rack close to the moving belt is fixedly connected with a push plate, and one end of the rack far from the push plate is fixedly connected with a limit tooth.

[0011] With the above technical solution, when adjusting according to the required angle in this solution, turn the second knob. The second knob will drive the bevel gear fixedly connected thereto to rotate. The bevel gear will drive the shaft body to rotate through the bevel gear meshing with it, thereby driving the gear fixedly connected to the shaft body to rotate. The rotation of the gear will drive the rack meshing with it to move. The movement of the rack will push the moving belt to move through the push plate. At this time, the movement of the moving belt will drive the brush to move along the length direction of the moving groove, thus forming a certain angle. This can adapt to the corners with different angles.

[0012] A further improvement of the technical solution of the present utility model lies in that: the locking assembly includes a transmission shaft. The transmission shaft is located at the end of the rotating shaft away from the slider. The rotating shaft is connected to the transmission shaft through a spline structure. A tension spring is fixedly connected to the end of the rotating shaft close to the transmission shaft. The other end of the tension spring is fixedly connected to the transmission shaft. The tension spring is located inside the transmission shaft. A second knob is fixedly connected to the end of the transmission shaft away from the rotating shaft. A limiting plate is fixedly connected to the outer side of the transmission shaft. The limiting plate is slidably connected to the chute.

[0013] With the above technical solution, when it is necessary to adjust the moving part in this solution, pull and rotate the second knob. Because the transmission shaft and the rotating shaft are connected through a spline structure, the rotation of the transmission shaft will drive the rotation of the rotating shaft. At the same time, the transmission shaft and the rotating shaft are slidably connected. When pulling the transmission shaft, the tension spring is in a stretched state at this time. Then, after rotating a certain angle, release the second knob. At this time, the tension spring resets, driving the limiting plate to move downward and then getting stuck inside the chute, thereby achieving the locking effect.

[0014] A further improvement of the technical solution of the present utility model lies in that: a limiting block is fixedly connected inside the moving groove.

[0015] With the above technical solution, the reason for fixedly connecting and arranging a limiting block inside the moving groove in this solution is to prevent the brush from being wound and pulled, resulting in the fracture of the pressure spring. The arrangement of the limiting block can better protect the pressure spring from being damaged, thereby reducing the probability of the device malfunctioning.

[0016] A further improvement of the technical solution of the present utility model lies in that: a smooth layer is provided on the surface of the push plate close to the moving belt.

[0017] With the above technical solution, the reason for providing a smooth layer on the surface of the push plate close to the moving belt in this solution is to reduce the friction generated between the push plate and the moving belt due to sliding, thereby extending the service life of the moving belt.

[0018] A further improvement of the technical solution of the present utility model lies in that: the material of the moving belt is nylon.

[0019] With the above technical solution, in this solution, the material of the moving belt is set to nylon because nylon has good flexibility, good deformation and bending recovery ability. Nylon also has the characteristics of high strength and high durability, making it have good wear resistance and durability at the same time.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by this utility model compared with the prior art is as follows:

[0021] 1. This utility model provides a paintbrush with inclined bristles. When painting wall corners at different angles, by adjusting the cooperation of the control component and the moving component, the moving belt can be driven to lift the brush, and at the same time, the moving belt will also act on the adjacent brush. At this time, the compression spring is in a stretched state, so that a number of uniformly arranged brushes can be combined to form different shapes, thus adapting to painting work at different angles. Such a setting not only enables the paintbrush to adapt to more wall corners at different angles, but also makes it more convenient to switch angles, thereby improving the working efficiency of the device.

[0022] 2. This utility model provides a paintbrush with inclined bristles. When painting wall corners at different angles, by turning the first knob, the screw rod fixedly connected thereto can be driven to rotate. The rotation of the screw rod will drive the slider slidably connected to the brush handle to move along the axis direction of the screw rod, so as to achieve the purpose of adjusting the position of the moving component.

[0023] 3. This utility model provides a paintbrush with inclined bristles. When adjusting according to the required angle, turn the second knob. The second knob will drive the bevel gear fixedly connected thereto to rotate. The bevel gear will drive the shaft body to rotate through the meshing bevel gear, thereby driving the gear fixedly connected to the shaft body to rotate. The rotation of the gear will drive the rack engaged therewith to move. The movement of the rack will push the moving belt to move through the push plate. At this time, the movement of the moving belt will drive the brush to move along the length direction of the moving groove, thus forming a certain included angle. This can adapt to wall corners with different included angles. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the moving belt 10 will also act on the adjacent brush 4. At this time, the compression spring 7 is in a stretched state, so that a plurality of brushes 4 arranged evenly can be combined into different shapes, so as to adapt to different angles for painting work. Such a setting not only enables the paintbrush to adapt to more wall corners at different angles, but also makes it more convenient to switch angles, thus improving the working efficiency of the device.

[0039] As Figure 6 shown, preferably, the locking component includes a transmission shaft 22. The transmission shaft 22 is located at the end of the rotating shaft 15 away from the slider 14. The rotating shaft 15 is connected to the transmission shaft 22 through a spline structure. A tension spring 23 is fixedly connected to the end of the rotating shaft 15 close to the transmission shaft 22. The other end of the tension spring 23 is fixedly connected to the transmission shaft 22. The tension spring 23 is located inside the transmission shaft 22. A second knob 24 is fixedly connected to the end of the transmission shaft 22 away from the rotating shaft 15. A limiting plate 25 is fixedly connected to the outside of the transmission shaft 22.

[0041] As Figure 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a limiting block 26 is fixedly connected inside the moving groove 3.

[0042] In this embodiment, the limiting block 26 is fixedly connected inside the moving groove 3 to prevent the brush 4 from being wound and pulled, resulting in the fracture of the compression spring 7.

[0044] In this embodiment, by providing a smooth layer on the surface of the push plate 20 close to the moving belt 10, the friction generated between the push plate 20 and the moving belt 10 due to sliding is reduced, thereby extending the service life of the moving belt 10. Embodiment 4

[0045] As Figure 2 shown, on the basis of Embodiment 3, the present utility model provides a technical solution: Preferably, the material of the moving belt 10 is nylon.

[0046] In this embodiment, the material of the moving belt 10 is set to nylon because the nylon material has good flexibility, good deformation and bending recovery capabilities. The nylon material also has the characteristics of high strength and high durability, making it have good wear resistance and durability at the same time.

[0047] Next, specifically describe the working principle of this paintbrush with inclined bristles.

[0048] As Figures 1-6As shown, when it is necessary to paint the wall corners at different angles, the control component and the moving component can be adjusted to cooperate with each other to drive the moving belt 10 to lift the brush 4. At the same time, the moving belt 10 will also act on the adjacent brush 4. At this time, the compression spring 7 is in a stretched state, so that a number of uniformly arranged brushes 4 can be combined to form different shapes, so as to adapt to painting work at different angles. Such a setting not only enables the paintbrush to adapt to more wall corners at different angles, but also makes it more convenient to switch angles, thus improving the working efficiency of the device. When it is necessary to paint the wall corners at different angles, the first knob 13 can be twisted to drive the screw rod 12 fixedly connected thereto to rotate. The rotation of the screw rod 12 will drive the slider 14 slidably connected to the brush handle 1 to move along the axis direction of the screw rod 12, so as to achieve the purpose of adjusting the position of the moving component. When adjusting according to the required angle, the second knob 24 is twisted. The second knob 24 will drive the bevel gear 16 fixedly connected thereto to rotate. The bevel gear 16 will drive the shaft body 17 to rotate through the meshing bevel gear 16, thereby driving the gear 18 fixedly connected to the shaft body 17 to rotate. The rotation of the gear 18 will drive the rack 19 engaged therewith to move. The movement of the rack 19 will push the moving belt 10 to move through the push plate 20. At this time, the movement of the moving belt 10 will drive the brush 4 to move along the length direction of the moving groove 3, so as to form a certain included angle. This can adapt to wall corners with different included angles. When it is necessary to adjust the moving component, the second knob 24 is pulled and rotated. Since the transmission shaft 22 and the rotating shaft 15 are connected by a spline structure, the rotation of the transmission shaft 22 will drive the rotating shaft 15 to rotate. At the same time, the transmission shaft 22 is slidably connected to the rotating shaft 15. When the transmission shaft 22 is pulled, the elastic spring 23 is in a stretched state at this time. Then, after rotating a certain angle and releasing the second knob 24, the elastic spring 23 resets, driving the limiting plate 25 to move downward and then getting stuck inside the sliding groove 2, so as to achieve the locking effect. A limiting block 26 is fixedly connected in the moving groove 3 to prevent the brush 4 from being wound and pulled, resulting in the fracture of the compression spring 7. The setting of the limiting block 26 can better protect the compression spring 7 from being damaged, thereby reducing the probability of the device malfunctioning. By providing a smooth layer on the surface of the push plate 20 close to the moving belt 10, the friction generated between the push plate 20 and the moving belt 10 due to sliding can be reduced, thereby extending the service life of the moving belt 10. By setting the material of the moving belt 10 to nylon, because nylon material has good flexibility, good deformation and bending recovery ability, and nylon material also has the characteristics of high strength and high durability, making it have good wear resistance and durability at the same time.
