Description

Technical Field

[0001] This application relates to the field of wall construction, and in particular to an adjustable roller brush. Background Technology

[0002] In wall construction, roller brushes are a commonly used tool, widely used for applying paints and varnishes. Traditional roller brushes typically include a fixed handle and a roller shaft with the brush head mounted on it. However, this traditional design has some limitations.

[0003] When working on higher walls, workers often need to use ladders or other auxiliary tools, which not only increases the complexity and danger of the work but also reduces work efficiency. To solve this problem, workers usually find a wooden stick or other long pole on the construction site as an extension pole and temporarily fix it to the handle of the roller brush so that they can reach the high wall more easily.

[0004] When fixing the extension rod to the handle, it is usually done by directly inserting the extension rod into the handle and using the friction between the handle and the extension rod to fix it. However, this temporary fixing method is often not stable enough, and the extension rod is easy to loosen or fall off the handle, which makes it inconvenient to operate when using the roller brush. Utility Model Content

[0005] The purpose of this application is to address the problem in the background art where the extension rod is typically inserted directly into the handle and fixed using the friction between the handle and the extension rod. However, this temporary fixing method is often unstable, and the extension rod is prone to loosening or falling off the handle, leading to inconvenience during roller brush operation. This application provides an adjustable roller brush.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An adjustable roller brush includes a roller shaft with a brush surface fixed on it. A connecting rod is rotatably connected to one end of the roller shaft. A handle is provided at the end of the connecting rod away from the roller shaft. One end of the handle is open. An angle adjustment mechanism is provided between the handle and the connecting rod. A clamping mechanism is provided on the handle.

[0008] By adopting the above technical solution, construction workers generally find an extension pole at the construction site. The extension pole can be a wooden stick or other long pole. One end of the extension pole is inserted into the handle, and then the clamping mechanism is used to clamp and fix the extension pole, so that the extension pole can be stably connected to the handle. This can further improve the stability of the handle and the external extension pole, and reduce the possibility of movement between the handle and the extension pole during the operation of the roller brush, which may cause the roller brush to be difficult to operate.

[0009] Furthermore, the clamping mechanism includes a plurality of clamping rods arranged in a circular pattern inside the handle, one end of each clamping rod is fixed with an inclined rod, a tightening assembly is provided between the plurality of inclined rods and the handle, and a moving assembly is provided on the handle.

[0010] By adopting the above technical solution, after the external extension rod is inserted into the handle, the tightening component drives the tilting rod and the clamping rod to clamp the clamping rod on the external extension rod. This improves the stability between the handle and the external extension rod and reduces the possibility of movement between the handle and the extension rod during roller brush operation, which could lead to difficulty in operating the roller brush or the handle falling off.

[0011] Furthermore, the tightening assembly includes a frustum-shaped cylinder fixed to the handle, with a storage cylinder fixed to one end of the frustum-shaped cylinder.

[0012] By adopting the above technical solution, the tilting rod is located in the frustum cylinder and abuts against the inner wall of the frustum cylinder. At the same time, the storage cylinder covers the clamping rod, which makes it easy for the tilting rod to move along the frustum cylinder and for several clamping rods to gradually approach each other.

[0013] Furthermore, a movable block is provided inside the handle, and several movable rods distributed in a circle are slidably connected to the movable block. The movable rods are fixedly connected to the end of the tilting rod away from the clamping rod.

[0014] By adopting the above technical solution, the moving block drives the moving rod to move in the handle, thereby making it convenient for the tilting rod to move in the frustum cylinder.

[0015] Furthermore, two symmetrical sliding blocks are fixed on the movable block, and a sliding groove corresponding to the sliding block is opened on the handle. The sliding block is located in the sliding groove and is slidably connected to the handle.

[0016] By adopting the above technical solution, the moving block drives the sliding block, allowing the sliding block to move in the sliding groove, thereby enabling the moving block to move stably.

[0017] Furthermore, the movable component includes a connecting ring sleeved on the handle, the connecting ring being fixedly connected to two sliding blocks, and a threaded ring being rotatably connected to the connecting ring, the threaded ring being threadedly connected to the handle.

[0018] By adopting the above technical solution, the threaded ring moves on the handle, and the threaded ring drives the connecting ring to move, thereby making it convenient for the sliding block to drive the moving block to move.

[0019] Furthermore, the angle adjustment mechanism includes an adjustment block one fixed on the handle, an adjustment block two provided on one side of the adjustment block one, the adjustment block two being fixedly connected to the connecting rod, a fixing bolt being threaded onto the adjustment block one, one end of the fixing bolt passing through the adjustment block two and fixing a limit block.

[0020] By adopting the above technical solution, the second adjusting block rotates along the fixing bolt on the first adjusting block, thereby facilitating the adjustment of the angle between the roller shaft and the handle. This reduces the possibility of the extension rod tilting excessively, which could make the roller brush operation difficult.

[0021] Furthermore, both the first and second adjustment blocks are fixed with a number of circumferentially distributed limiting teeth that mesh with each other.

[0022] By adopting the above technical solution, when the first adjusting block and the second adjusting block come into contact, the limiting teeth on the first adjusting block and the second adjusting block engage together, thereby improving the stability of the first adjusting block and the second adjusting block coming into contact.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, after the construction personnel use locally sourced materials to extend the rod, they insert the extended rod into the storage cylinder. Then, they rotate the threaded ring, causing the threaded ring to move on the handle. The threaded ring drives the connecting ring, the connecting ring drives the sliding block, the sliding block drives the moving block, the moving block drives the connecting rod, the connecting rod drives the tilting rod, and the tilting rod drives the clamping rod. During the movement of the tilting rod, the tilting rods move closer to each other under the constraint of the inner wall of the frustum cylinder. With the support of the moving rod, the tilting rods drive the clamping rods to move closer to each other, so that the clamping rods clamp and abut against the external extended rod. This achieves the purpose of improving the stability between the handle and the external extended rod, reducing the possibility of movement between the handle and the extended rod during the operation of the roller brush, which could lead to difficulty in operating the roller brush or the handle falling off.

[0025] 2. In this application, by rotating the fixing bolt, the fixing bolt moves on the adjusting block one, causing the adjusting block one to move away from the adjusting block two, thus separating the limiting teeth between the adjusting block one and the adjusting block two. Then, the adjusting block two rotates on the fixing bolt, causing the connecting rod to rotate to a suitable angle. After that, the fixing bolt is rotated, causing the fixing bolt to move the limiting block, which in turn moves the adjusting block two, causing the limiting teeth on the adjusting block two and the adjusting block one to re-engage. This completes the adjustment of the angle between the roller shaft and the handle, making it convenient to adjust the angle between the roller shaft and the handle. This reduces the possibility of excessive tilting of the extension rod during use, which could lead to difficulties in operating the roller brush. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0034] This application discloses an adjustable roller brush.

[0035] Reference Figure 1 , Figure 2 and Figure 3 An adjustable roller brush includes a roller shaft 1, a brush surface 2 fixed on the roller shaft 1, a connecting rod 3 rotatably connected to one end of the roller shaft 1, a handle 4 provided at the end of the connecting rod 3 away from the roller shaft 1, one end of the handle 4 being open, an angle adjustment mechanism 6 provided between the handle 4 and the connecting rod 3, and a clamping mechanism 5 provided on the handle 4.

[0036] When using this roller brush, hold the handle 4 directly, then immerse the brush surface 2 on the roller shaft 1 into the paint. Use the handle 4 to drive the connecting rod 3, which in turn drives the roller shaft 1. This allows the brush surface 2 on the roller shaft 1 to press against the wall surface for brushing. If the wall is too high, the worker will typically find an extension pole (a wooden stick or other long pole) at the work site. Insert one end of the extension pole into the handle 4, and then use the clamping mechanism 5 to hold and secure the extension pole, ensuring a stable connection between the extension pole and the handle 4. The worker then holds the extension pole and raises the handle 4. The roller shaft 1 is used to brush the brush surface 2 on higher wall surfaces. During use, the angle adjustment mechanism 6 can be used to adjust the angle between the roller shaft 1 and the handle 4, making it easier for the roller shaft 1 to reach into some corners. When it is necessary to brush higher wall surfaces, the construction workers can find an extension rod on-site and insert it into the handle 4. The clamping mechanism 5 is used to further clamp the extension rod inserted into the handle 4, thereby further improving the stability of the handle 4 and the external extension rod and reducing the possibility of movement between the handle 4 and the extension rod during the brushing operation, which could lead to difficulty in operating the brush.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The clamping mechanism 5 includes several clamping rods 51 arranged in a circular pattern inside the handle 4. One end of each clamping rod 51 is fixed with an inclined rod 52. A tightening component 53 is provided between the inclined rods 52 and the handle 4. A moving component 54 is provided on the handle 4.

[0038] In addition, the tightening component 53 includes a frustum cylinder 531 fixed to the handle 4, and a storage cylinder 532 is fixed to one end of the frustum cylinder 531.

[0039] Furthermore, a movable block 533 is provided inside the handle 4, and several movable rods 534 arranged in a circle are slidably connected to the movable block 533. The movable rods 534 are fixedly connected to the end of the tilting rod 52 away from the clamping rod 51.

[0040] Furthermore, two symmetrical sliding blocks 535 are fixed on the moving block 533, and a sliding groove 536 corresponding to the sliding block 535 is provided on the handle 4. The sliding block 535 is located in the sliding groove 536 and is slidably connected to the handle 4.

[0041] Furthermore, the movable component 54 includes a connecting ring 542 sleeved on the handle 4, the connecting ring 542 being fixedly connected to two sliding blocks 535, and a threaded ring 541 being rotatably connected to the connecting ring 542, the threaded ring 541 being threadedly connected to the handle 4.

[0042] After the construction workers used readily available materials to extend the rod, they inserted it into the storage cylinder 532. Then, they rotated the threaded ring 541, causing it to move on the handle 4. The threaded ring 541 drove the connecting ring 542, which in turn drove the sliding block 535. The sliding block 535 then drove the moving block 533, which in turn drove the connecting rod 3. The connecting rod 3 then drove the tilting rod 52, which in turn drove the clamping rod 51. During the movement of the tilting rod 52, it moved closer to each other under the constraint of the inner wall of the frustum cylinder 531, tilting... Supported by the moving rod 534, the rod 52 drives the clamping rods 51 to move closer together, so that the clamping rods 51 clamp and abut against the external extension rod. By causing the sliding block 535 to drive the moving rod 534, the moving rod 534 drives the tilting rod 52 to move inward toward the handle 4, so that the clamping rod 51 on the tilting rod 52 clamps the external extension rod inserted into the handle 4. This can improve the stability between the handle 4 and the external extension rod, and reduce the possibility of movement between the handle 4 and the extension rod during the operation of the roller brush, which may cause the roller brush to be difficult to operate or the handle 4 to fall off.

[0043] Reference Figure 3 and Figure 5 The angle adjustment mechanism 6 includes an adjustment block 61 fixed on the handle 4, an adjustment block 62 on one side of the adjustment block 61, the adjustment block 62 being fixedly connected to the connecting rod 3, a fixing bolt 63 being threaded onto the adjustment block 61, one end of the fixing bolt 63 passing through the adjustment block 62 and fixing a limit block 64.

[0044] In addition, both the first adjusting block 61 and the second adjusting block 62 are fixed with several circumferentially distributed limiting teeth 65, which mesh with each other.

[0045] When it is necessary to adjust the angle between the roller shaft 1 and the handle 4, rotate the fixing bolt 63 to move the fixing bolt 63 on the adjusting block 1 61. This causes the adjusting block 1 61 to move the limiting block 64 away from the adjusting block 2 62, separating the limiting teeth 65 between the adjusting block 1 61 and the adjusting block 2 62. Then, rotate the adjusting block 2 62 on the fixing bolt 63. After the adjusting block 2 62 drives the connecting rod 3 to rotate to the appropriate angle, rotate the fixing bolt 63 to drive the limiting block 64. This causes the limiting block 64 to drive the adjusting block 2 62, allowing the limiting teeth 65 on the adjusting block 2 62 and the adjusting block 1 61 to re-engage, thus completing the adjustment of the angle between the roller shaft 1 and the handle 4. By having the adjusting block 2 62 drive the roller shaft 1 and the adjusting block 1 61 drive the handle 4, the angle between the adjusting block 1 61 and the adjusting block 2 62 can be adjusted along the fixing bolt 63. This makes it convenient to adjust the angle between the roller shaft 1 and the handle 4, reducing the possibility of excessive tilting of the extension rod during use, which could make the roller brush operation difficult.

[0046] Working principle: When using this roller brush, hold the handle 4 directly, then immerse the brush surface 2 on the roller shaft 1 into the paint. Use the handle 4 to drive the connecting rod 3, which in turn drives the roller shaft 1. This allows the brush surface 2 on the roller shaft 1 to press against the wall surface for brushing. If the wall is too high, the worker typically uses an extension rod (wooden stick or other long pole) inserted into the storage cylinder 532. Then, rotate the threaded ring 541, moving it on the handle 4. The threaded ring 541 drives the connecting ring 542, which in turn drives the sliding block 535. The sliding block 535 then drives the moving block 533, which in turn drives the connecting rod 3. The connecting rod 3 then drives the tilting rod 52, which in turn drives the clamping rod 51. During the movement of the tilting rod 52, it is restrained by the inner wall of the frustum-shaped cylinder 531. As the tilting rod 52 approaches, supported by the moving rod 534, it drives the clamping rod 51 to approach each other, allowing the clamping rod 51 to clamp and abut against the external extension rod, thus stably connecting the extension rod to the handle 4. The fixing bolt 63 is rotated, causing it to move on the adjusting block 1 61, which in turn moves the limiting block 64 away from the adjusting block 2 62, separating the limiting teeth 65 between the adjusting block 1 61 and the adjusting block 2 62. Then, the adjusting block 2 62 rotates on the fixing bolt 63, causing the connecting rod 3 to rotate to a suitable angle. The fixing bolt 63 is then rotated, causing the limiting block 64 to move, which in turn moves the adjusting block 2 62, re-engaging the limiting teeth 65 on the adjusting block 2 62 and the adjusting block 1 61. This completes the adjustment of the angle between the roller shaft 1 and the handle 4. The construction worker then uses the brush surface 2 on the roller shaft 1 to roll and brush the wall surface.
