Technical Field

[0001] The utility model relates to the technical field of plastic pipe disassembly, in particular to a portable tool for disassembling plastic pipes embedded in walls. Background Art

[0002] During construction and maintenance, it's common to remove various pipes, including plastic pipes, embedded in walls. Traditional removal methods typically rely on manual tools, such as screwdrivers and crowbars. These tools present several challenges: They are difficult to operate in confined spaces, especially when pipes are deeply embedded in the wall, making it difficult to exert sufficient force to fully extract them. They are also susceptible to damage: improper operation or force control can easily lead to pipe rupture or deformation, increasing repair costs and time. Manual removal is also inefficient: the process is time-consuming and labor-intensive, reducing work efficiency.

[0003] In order to solve the above problems, we propose a portable tool for dismantling plastic pipes embedded in walls. This portable tool is specifically designed for dismantling plastic pipes embedded in walls and can be adjusted to adapt to plastic pipes of different diameters. Summary of the Invention

[0004] In order to overcome the shortcomings of traditional disassembly methods that usually rely on manual tools such as screwdrivers, crowbars, etc., which are difficult to disassemble, inefficient, and easily damage plastic pipes, the utility model provides a portable tool for disassembling plastic pipes embedded in walls.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0022] Example 1: A portable tool for removing plastic pipes embedded in a wall, such as Figures 1-6 As shown, it includes a fixing tube 1, a fixing ring 2, a first connecting plate 3, a top plate 4, a tightening plate 5, a first nut 6, a connecting frame 7, a connecting ring 8, a second connecting plate 9, a cleaning component and an extension component. The left part of the fixing tube 1 is fixedly connected to the fixing ring 2, and three top plates 4 are equidistantly arranged around the outside of the fixing tube 1. A connecting ring 8 surrounding the fixing tube 1 is arranged on the right side of the fixing ring 2. The left end of the top plate 4 is movably connected to the left end of the fixing tube 1, the middle part of the top plate 4 is movably connected to the fixing ring 2 through the first connecting plate 3, and the right end of the top plate 4 is movably connected to the connecting ring 8 through the second connecting plate 9. The outside of the top plate 4 is fixedly connected to a tightening plate 5, and the surface of the tightening plate 5 is provided with equidistantly distributed rubber strips for increasing friction. The right part of the fixing tube 1 is threadedly connected to the first nut 6, and the connecting frame 7 is rotatably connected to the first nut 6. The left end of the connecting frame 7 is fixedly connected to the connecting ring 8. A cleaning component for cleaning the inner wall of the plastic tube is provided on the fixing tube 1, and an extension component for extending the length is provided on the fixing tube 1.

[0023] When the fixing tube 1 is pulled to the right, the entire device can be driven to move to the right. Under the action of friction, the sticking plate 5 can be pulled out of the wall.

[0024] Example 2: Based on Example 1, Figure 1 and Figure 3 As shown, the cleaning assembly includes a mounting block 10, a motor 11 and a brush plate 12. The left end of the fixed tube 1 is fixedly connected to the mounting block 10, the motor 11 is fixedly connected to the mounting block 10, and the brush plate 12 is fixedly connected to the output shaft of the motor 11.

[0025] When using the device, the staff starts the motor 11, and the output shaft of the motor 11 rotates to drive the brush plate 12 to rotate. When the device is inserted into the plastic pipe, the rotation of the brush plate 12 can clean the impurities on the inner wall of the plastic pipe to prevent dust from affecting the adhesion of the pressing plate 5 to the inner wall of the plastic pipe. When the device is finished using, the staff turns off the motor 11.

[0026] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the extension assembly includes a second nut 13, a connecting rod 131, an extrusion ring 14, a clamping piece 15 and an extension rod 16. The right end of the fixed tube 1 is connected to the second nut 13 by a thread. The second nut 13 is fixedly connected to the connecting rods 131 that are equidistantly distributed around the circumference. The extrusion ring 14 is fixedly connected between the right ends of the connecting rods 131. The right side of the fixed tube 1 is fixedly connected to the clamping piece 15. The clamping piece 15 is provided with four elastic petals and is tapered as a whole. The extrusion ring 14 is extruded and fitted with the clamping piece 15. The extension rod 16 is slidably connected to the inside of the fixed tube 1, and a pull ring is fixedly connected to the right side of the extension rod 16.

[0027] When using this device, the staff can control the extension rod 16 to slide left and right in the fixed tube 1 to adjust the length to adapt to plastic pipes of different depths. When the length is adjusted, the staff controls the second nut 13 to rotate, and the second nut 13 moves to the left while rotating. The second nut 13 moves to the left and drives the extrusion ring 14 to move to the left through the connecting rod 131. The extrusion ring 14 moves to the left to extrude the clamping part 15, causing the clamping part 15 to deform and clamp the extension rod 16, thereby fixing the position of the extension rod 16.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
