Description

Technical Field

[0001] This application relates to the field of building waterproofing construction tools, and in particular to a multifunctional pipe root surface treatment tool. Background Technology

[0002] In building waterproofing projects, the pipe roots (hereinafter referred to as "pipe roots") in areas such as bathrooms and kitchens are high-frequency weak points where leaks occur. The current standard construction process is to apply waterproof coatings or wrap waterproof membranes around the pipe roots for sealing and reinforcement.

[0003] However, existing technologies have many shortcomings: Adhesion challenges: Common PVC and PPR plastic pipes have smooth surfaces, making it difficult for waterproof coatings to adhere firmly. If the substrate is not properly prepared, the coating is prone to peeling off due to stress changes during later use, leading to leaks.

[0004] Inefficient and ineffective surface treatment: To increase the surface roughness of pipes, the industry commonly uses manual sanding around the pipes with handheld sandpaper. This method is time-consuming, labor-intensive, and the uniformity of the sanding depends entirely on the worker's experience, making it difficult to guarantee consistent treatment quality and thus creating potential for leakage.

[0005] Waterproof membrane cutting precision issues: For processes requiring the wrapping of waterproof membrane rolls, installers must cut the rolls into rings of specific sizes according to the pipe diameter. Traditional manual cutting using scissors or utility knives easily produces burrs and dimensional deviations (too large or too small), affecting the sealing effect. Cutting too small prevents installation, while cutting too large requires overlapping, creating new weak points.

[0006] Separation of processes and cumbersome tools: Grinding pipe roots and cutting roll material are two separate processes. Construction workers need to use different tools alternately. Frequent switching not only reduces the overall construction efficiency, but also increases the complexity of tool management and personnel operation.

[0007] Limitations of existing power tools: In recent years, although some electric sanders have emerged to improve efficiency, they generally suffer from the following problems: High cost: Electric equipment is much more expensive than simple hand tools.

[0008] Poor flexibility: Its grinding head (such as grinding wheel) has a fixed specification, and it is difficult for one machine to adapt to the common pipe diameter range from DN20 to DN110. It is necessary to equip multiple specifications of grinding heads, which increases the cost and carrying burden.

[0009] Limited functionality: It only has a sanding function and cannot solve the problem of cutting roll materials.

[0010] Safety risks: Using electrical equipment in damp environments such as bathrooms poses certain safety hazards.

[0011] The related technology, disclosed in CN222661907U, describes a cutting device for additional layers at the root of waterproof membrane pipes, which uses a motor-driven abrasive belt to grind the pipes. While this technology improves efficiency to some extent, it still fails to solve the aforementioned problems of adaptability, limited functionality, and electrical safety in humid environments. Its complex structure also makes it difficult to replace grinding components adapted to different pipe diameters. Utility Model Content

[0012] To address the limitations of existing multi-functional pipe root surface treatment tools due to their design features, the inventors have identified issues with adaptability, limited functionality, and electrical safety in humid environments. Furthermore, their complex structures and the difficulty in replacing grinding components to accommodate different pipe diameters hinder the development of a multi-functional pipe root surface treatment tool. This application provides a different solution.

[0013] The multifunctional pipe root surface treatment tool provided in this application adopts the following technical solution: it includes an adjusting column with a threaded structure, an adjusting seat adapted to the adjusting column, a fixing part connected to the adjusting seat, a rotating part rotatably connected to the fixing part, a handheld part fixedly disposed on one side of the rotating part, and a cutting assembly connected to the rotating part. The above technical solution includes a threaded adjusting column, a compatible adjusting seat, a connecting fixing part, a rotatably connected rotating part, a fixedly mounted handheld part, and a cutting assembly connected to the rotating part. The adjusting seat and adjusting column are threaded together, allowing the fixing part to adjust the outer diameter of the pipe root, thus adapting to pipe roots of different inner diameters. Furthermore, by adjusting the distance of the cutting assembly relative to the pipe root mounting surface, the cutting position of the cutting assembly can be adjusted, ensuring cutting efficiency.

[0014] As a preferred embodiment, the outer periphery of the adjusting column is provided with an external thread, and the inner wall of the adjusting seat is provided with an internal thread that matches the external thread on the outer periphery of the adjusting column.

[0015] By adopting the above technical solution, the adjusting seat and adjusting column are threaded together, allowing the fixing part to adjust the inner diameter of the pipe root, thus adapting to pipe roots of different inner diameters. Furthermore, by adjusting the distance between the cutting assembly and the pipe root mounting surface, the cutting position of the cutting assembly can be adjusted, ensuring cutting efficiency.

[0016] As a preferred embodiment, the rotating part is located at the end of the adjusting seat away from the fixed part, and a sealed bearing is provided at the connection between the adjusting seat and the rotating part.

[0017] By adopting the above technical solution, the rotating part can rotate freely relative to the adjusting seat, and the sealed bearing ensures that there is no leakage during rotation, thus enhancing the flexibility of the device.

[0018] As a preferred embodiment, the fixing part includes a first fixing claw disposed on one side of the adjusting seat, a second fixing claw disposed on the other side of the adjusting seat, a first connecting seat respectively fixedly disposed on the outer periphery of the adjusting seat, and a second connecting seat hinged to the end of the adjusting column. The first fixing claw and the second fixing claw are configured as arc-shaped claws, and anti-slip pads are respectively provided on the outer sides of the first fixing claw and the second fixing claw.

[0019] By adopting the above technical solution, the fixing part includes a first fixing claw and a second fixing claw, which are arc-shaped. They can not only hold the object tightly, but also have anti-slip pads on the outside to increase friction and prevent instability in fixing the pipe root.

[0020] As a preferred embodiment, the first connecting seat is rotatably connected to the first fixed gripper and the second fixed gripper, and the other ends of the first fixed gripper and the second fixed gripper are rotatably connected to the other end of the second connecting seat.

[0021] By adopting the above technical solution, the first connecting seat is rotatably connected to the first fixed jaw and the second fixed jaw, allowing the jaws to adjust their angle as the adjusting seat moves; the second connecting seat is hinged to the end of the second fixed jaw and the adjusting column, realizing the overall rotation function. The working principle is as follows: when the fixing part moves with the adjusting seat, the rotational connection between the first and second connecting seats allows the first and second fixed jaws to adapt to pipe fittings with different inner diameters. The anti-slip pads on the outer sides of the first and second fixed jaws increase friction, and the first and second fixed jaws penetrate deep into the inner cavity of the pipe to tighten the inner wall of the pipe, ensuring the stability of the pipe fitting during fixing.

[0022] As a preferred embodiment, the cutting assembly is detachably connected to the rotating part, and the cutting assembly includes a blade holder detachably connected to the rotating part, a cutting head connected to the blade holder, and an adjustment assembly disposed between the cutting head and the blade holder.

[0023] By adopting the above technical solution, the adjustment component facilitates the adjustment of the radial extension length of the cutting head, thereby precisely setting the annular diameter of the pipe root to be cut. Furthermore, it facilitates the rotation of the rotating part via the handheld part, converting the circular motion of the rotating part into the radial feed motion of the cutting head or a circular motion that maintains a constant position.

[0024] As a preferred embodiment, the adjustment assembly includes an adjustment blade holder fixedly disposed on one side of the cutting head and an adjustment bolt passing through the blade holder and connecting to the adjustment blade holder, wherein the adjustment bolt and the adjustment blade holder are connected by a threaded structure.

[0025] By adopting the above technical solution, the adjusting assembly, through the adjusting bolt and the adjusting blade holder, enables the cutting head to be adjusted in the radial direction, thereby precisely setting the annular diameter of the pipe root to be cut. Specifically, the adjusting bolt passes through the blade holder and the adjusting blade holder, and is connected to the adjusting blade holder through a threaded structure. Rotating the adjusting bolt can adjust the radial extension length of the cutting head.

[0026] As a preferred embodiment, it further includes a polishing assembly connected to the rotating part, the polishing assembly being detachably connected to the rotating part, and the polishing assembly being an annular belt or polishing sleeve with abrasive material attached.

[0027] By adopting the above technical solution, the grinding component is connected to the rotating part in a detachable manner. According to different usage requirements, a suitable abrasive material can be selected and attached to the annular belt or grinding sleeve, thereby achieving efficient grinding of different materials and surfaces. The circular motion of the rotating part is transformed into the circular grinding motion of the grinding sleeve.

[0028] In summary, this application includes the following beneficial technical effects: 1. The threaded adjusting column, through its threaded engagement with the adjusting seat, allows for adjustment of the inner diameter of the fixing part, thus making it suitable for pipe roots with different inner diameters; the threaded structure of the adjusting seat fixing part ensures tightness of the contact surface and enhances the fixing effect. 2.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application discloses a multifunctional pipe root surface treatment tool. It includes a threaded adjustment column 100, an adjustment seat 1 adapted to the adjustment column 100, a fixing part connected to the adjustment seat 1, a rotating part 41 rotatably connected to the fixing part, a handheld part 5 fixedly disposed on one side of the rotating part 41, and a cutting assembly connected to the rotating part 41. The central axes of the rotating part 41, the adjustment seat 1, the fixing part, and the cutting assembly coincide to accommodate annular operation around the pipe root. Please refer to the details. Figure 3 , Figure 4 and Figure 5 The adjusting seat 1 and the adjusting column 100 are threaded together, allowing the fixing part to adjust the inner diameter of the pipe root, thus adapting to pipe roots of different inner diameters. Furthermore, the distance between the cutting component and the pipe root mounting surface is adjusted, thereby achieving adjustment of the cutting position of the cutting component and ensuring cutting efficiency. In terms of working principle, the user first adjusts the inner diameter of the fixing part to match the pipe root size through the threaded connection between the adjusting column 100 and the adjusting seat 1, and then adjusts the relative distance between the cutting component and the pipe root mounting surface. Finally, the user holds the handheld part 5 and rotates the rotating part 41 to perform the cutting operation. Through mechanical rotation around the pipe root, the cutting task of the pipe root is completed accurately and effectively.

[0033] Please refer to the details. Figure 1 and Figure 3The adjusting column 100 has an external thread on its outer periphery, and the adjusting seat 1 has an internal thread on its inner wall that matches the external thread on the outer periphery of the adjusting column 100. The adjusting seat 1 and the adjusting column 100 are connected by threads, allowing the fixing part to adjust the inner diameter of the pipe root, thus making it suitable for pipe roots with different inner diameters. Furthermore, the distance between the cutting assembly and the pipe root mounting surface is adjusted, thereby achieving adjustment of the cutting position of the cutting assembly and ensuring cutting efficiency.

[0034] Please refer to details. Figure 1 , Figure 2 and Figure 4 The rotating part 41 is located at the end of the adjusting seat 1 away from the fixed part, and a sealed bearing 411 is provided at the connection between the adjusting seat 1 and the rotating part 41. The rotating part 41 can rotate freely relative to the adjusting seat 1. The sealed bearing 411 ensures that there is no leakage during rotation, which enhances the flexibility of the device.

[0035] Please refer to details. Figure 1 , Figure 2 and Figure 3 The fixing part includes a first fixing claw 21 disposed on one side of the adjusting seat 1, a second fixing claw 22 disposed on the other side of the adjusting seat 1, a first connecting seat 31 respectively fixedly disposed on the outer periphery of the adjusting seat 1, and a second connecting seat 32 hinged to the end of the adjusting column 100. The first fixing claw 21 and the second fixing claw 22 are configured as arc-shaped claws, and anti-slip pads are respectively provided on the outer side of the first fixing claw 21 and the second fixing claw 22. The fixing part includes the first fixing claw 21 and the second fixing claw 22, which are arc-shaped. They can not only support the object, but also have anti-slip pads on the outside, which increases the friction and prevents the stability of fixing the pipe root.

[0036] Please refer to details. Figure 2 and Figure 3The first connecting seat 31 is rotatably connected to the first fixed jaw 21 and the second fixed jaw 22. The other ends of the first fixed jaw 21 and the second fixed jaw 22 are rotatably connected to the other end of the second connecting seat 32. The rotatable connection between the first connecting seat 31 and the first fixed jaw 21 and the second fixed jaw 22 allows the jaws to be adjusted in angle as the adjusting seat 1 moves. The second connecting seat 32 is hinged to the end of the second fixed jaw 22 and the adjusting column 100, realizing the overall rotation function. The working principle is as follows: When the fixed part moves with the adjusting seat 1, the rotational connection between the first connecting seat 31 and the second connecting seat 32 causes the outer sides of the first fixed jaw 21 and the second fixed jaw 22, which are deep into the inner cavity of the pipe root, to tighten the pipe root. This adapts to pipes with different inner diameters. The anti-slip pads on the first fixed jaw 21 and the second fixed jaw 22 increase the friction and ensure the stability of the connection between the first fixed jaw 21 and the second fixed jaw 22 and the pipe root. In this way, the fixing part can be flexibly applied to pipe fittings with various inner diameters, improving the flexibility and adaptability of use.

[0037] Please refer to details. Figure 3 , Figure 4 and Figure 5 The cutting assembly is detachably connected to the rotating part 41. The cutting assembly includes a blade holder 61 detachably connected to the rotating part 41, a cutting head 62 connected to the blade holder 61, and an adjustment assembly disposed between the cutting head 62 and the blade holder 61. The adjustment assembly facilitates the adjustment of the radial extension length of the cutting head 62, thereby precisely setting the annular diameter of the pipe root to be cut. Furthermore, it facilitates the rotation of the rotating part 41 via the handheld part 5, converting the circular motion of the rotating part 41 into the radial feed motion of the cutting head 62 or a circular motion maintaining a constant position.

[0038] Please refer to details. Figure 4 and Figure 5 The adjustment assembly includes an adjusting blade holder 621 fixedly mounted on one side of the cutting head 62 and an adjusting bolt 63 passing through the blade holder 61 and connecting to the adjusting blade holder 621. The adjusting bolt 63 and the adjusting blade holder 621 are connected by a threaded structure. The adjustment assembly, through the adjusting bolt 63 and the adjusting blade holder 621, allows the cutting head 62 to be adjusted in the radial direction, thereby precisely setting the annular diameter of the pipe root to be cut. Specifically, the adjusting bolt 63 passes through the blade holder 61 and the adjusting blade holder 621, and is connected to the adjusting blade holder 621 through a threaded structure. Rotating the adjusting bolt 63 adjusts the radial extension length of the cutting head 62. The working principle is that the circumferential motion of the rotating part 41 drives the blade holder 61 and the cutting head 62 to rotate, while the radial extension length of the cutting head 62 is finely adjusted by the adjusting bolt 63, thereby achieving precise cutting of pipes with the required diameter.

[0039] Please refer to details. Figure 1 and Figure 6 It also includes a polishing assembly 7 connected to the rotating part 41. The polishing assembly 7 is detachably connected to the rotating part 41 and is an annular belt or polishing sleeve with abrasive material applied to it. The polishing assembly 7 is detachably connected to the rotating part 41, and a suitable abrasive material can be selected to be applied to the annular belt or polishing sleeve according to different usage requirements, thereby achieving efficient polishing of different materials and surfaces. The circular motion of the rotating part 41 is converted into the circular polishing motion of the polishing sleeve.

[0040] The implementation principle of a multifunctional pipe root surface treatment tool according to an embodiment of this application is as follows: When in use, the first fixed clamp 21 and the second fixed clamp 22 extend into the inner cavity of the pipe root and are adjusted by the threaded engagement of the adjusting column 100 and the adjusting seat 1. When the fixed part moves with the adjusting seat 1, the first connecting seat 31 and the second connecting seat 32 are rotated and connected, so that the outer sides of the first fixed clamp 21 and the second fixed clamp 22 that are deep into the inner cavity of the pipe root support the pipe root, thereby adapting to pipes with different inner diameters. The anti-slip pads on the first fixed clamp 21 and the second fixed clamp 22 increase the friction and ensure the stability of the connection between the first fixed clamp 21 and the second fixed clamp 22 and the pipe root. The circular motion of the rotating part 41 drives the tool holder 61 and the cutting head 62 to rotate. The adjusting bolt 63 passes through the tool holder 61 and the adjusting tool holder 621, and is connected to the adjusting tool holder 621 through the threaded structure. Rotating the adjusting bolt 63 can adjust the radial extension length of the cutting head 62, thereby achieving precise cutting of pipes with the required diameter. If it is necessary to grind the outer periphery of the pipe root, remove the cutting assembly and install the grinding assembly 7. The grinding assembly 7 is connected to the rotating part 41 in a detachable manner. According to different usage requirements, a suitable abrasive material can be selected and attached to the annular belt or grinding sleeve to achieve efficient grinding of different materials and surfaces. The circular motion of the rotating part 41 is converted into the circular grinding motion of the grinding sleeve.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
