Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water pipe cutting auxiliary technology, specifically relating to a water pipe cutting precision positioning auxiliary device. Background Technology
[0002] For the pre-embedding of electromechanical installation pipes, a hacksaw, pipe cutter, or grinder is generally used for pipe cutting. The pipe to be cut is measured to the correct dimensions, placed securely in the jaws of the clamps, and then cut. The cut should be clean and straight, with the pipe end smooth and free of burrs, and any metal filings removed from the inside. However, during pipe installation, there is usually a certain amount of allowance left for further processing after installation. Cutting from the outside becomes more difficult at this point. Utility Model Content
[0003] In response to the shortcomings of existing technologies, the inventors have developed a precise positioning auxiliary device for water pipe cutting through long-term practice, which solves the problem of not being able to make precise cuts from the outside of the water pipe.
[0004] This utility model discloses a precise positioning auxiliary device for water pipe cutting, comprising a fixed circular tube and a movable circular tube sleeved on the fixed circular tube, the movable circular tube being able to slide freely on the fixed circular tube. A saw blade is disposed at the bottom of the fixed circular tube, and a ring of evenly arranged saw teeth is disposed around the outer periphery of the saw blade. A limiting plate is disposed at the bottom of the movable circular tube, and a handle is connected and fixed to the movable circular tube above the limiting plate, the handle being fixed to the movable circular tube by fasteners.
[0005] Furthermore, the fixed circular tube is a solid circular tube, and the movable circular tube is a hollow circular tube.
[0006] Furthermore, a sleeve is provided at the top of the fixed circular tube.
[0007] Furthermore, both the saw blade and the sleeve are welded and fixed to the fixed circular tube.
[0008] Furthermore, the height of the movable circular tube does not exceed half the height of the fixed circular tube.
[0009] Furthermore, the inner diameter of the movable circular tube is larger than the outer diameter of the fixed circular tube but does not exceed 1.5 times the outer diameter of the fixed circular tube.
[0010] Furthermore, the limiting disk is disc-shaped.
[0011] Furthermore, the outer diameter of the limiting disk is larger than the outer diameter of the moving circular tube.
[0012] Furthermore, the handle is fixed to the movable cylindrical tube by fastening screws.
[0013] The beneficial effects of this utility model are:
[0014] An adjustable sleeve device is used to cut water pipes from the inside. The device has an adjustable movable circular tube section that controls the cutting length, while the saw blade cuts from within the pipe, requiring minimal workspace. This device has a simple construction principle, is easy to manufacture and use, and is particularly effective for water pipes located deep underground in confined spaces where direct external measurements are impossible.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0020] See Figure 1 and Figure 2 This utility model proposes a precise positioning auxiliary device for water pipe cutting, including a fixed circular pipe 1 and a movable circular pipe 2 sleeved on the fixed circular pipe 1. In this embodiment, the fixed circular pipe 1 is a solid circular pipe. A sleeve 12 is provided at the top of the fixed circular pipe 1, which is used to connect to a special electric drill. A saw blade 11 is provided at the bottom of the fixed circular pipe 1. The saw blade 11 is disc-shaped, and a ring of evenly arranged saw teeth is provided on the outer periphery of the saw blade 11 for cutting water pipes.
[0021] In this embodiment, both the saw blade 11 and the sleeve 12 are welded and fixed to the fixed round tube 1.
[0022] The movable circular tube 2 is a hollow circular tube. The height of the movable circular tube 2 does not exceed half of the fixed circular tube 1, and the inner diameter of the movable circular tube 2 is greater than the outer diameter of the fixed circular tube 1 but does not exceed 1.5 times the outer diameter of the fixed circular tube 1. The movable circular tube 2 can slide freely on the fixed circular tube 1.
[0023] A limiting plate 21 is provided at the bottom of the movable circular tube 2. The limiting plate 21 is disc-shaped, and its outer diameter is larger than that of the movable circular tube 2. In this embodiment, the limiting plate 21 is welded and fixed to the movable circular tube 2. A handle 22 is connected and fixed to the movable circular tube 2 above the limiting plate 21. The handle 22 is connected and fixed to the movable circular tube 2 by fasteners 23. Specifically, the handle 22 is connected and fixed to the movable circular tube 2 by fastening screws.
[0024] The working principle of this utility model device is as follows:
[0025] First, insert one end of the saw blade 11 of the fixed round tube 1 into the water pipe to be cut. According to the length of the water pipe to be cut, slide the moving round tube 2 to the desired position. At this time, the limiting plate 21 is pressed against the end of the water pipe to be cut. Use a tape measure to measure the distance from the bottom of the saw blade 11 of the fixed round tube 1 to the limiting plate 21 of the moving round tube 2. This length is the length of the water pipe to be cut. Then, turn the operating handle 22 to a position convenient for cutting, tighten the fastening screw to fix the handle 22, connect the socket 12 to the special electric drill securely, start the electric drill, hold the handle 22 and move it along the circumference of the water pipe. The saw blade 11 cuts the water pipe from the inside until the cutting work is completed.
[0026] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
