Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, and specifically relates to a waterproof sleeve water-stop ring cutting device. Background Technology

[0002] During indoor water supply and drainage construction, water supply and drainage pipes need to penetrate walls. For pipes penetrating walls, protective sleeves are required. These sleeves effectively prevent water leakage from the gaps between the pipes and the walls, ensuring the dryness and safety of the building interior. Protective sleeves also reduce friction and damage caused by thermal expansion and contraction or building settlement, extending the pipes' lifespan. Furthermore, to further improve waterproofing, a water-stop ring is installed on the outer wall of the protective sleeve. This ring is typically welded to the sleeve and its function is to increase the path for water seepage, thereby significantly increasing the resistance to seepage and achieving impermeability. Therefore, in actual construction, water-stop rings need to be cut from a single piece of steel plate. Currently, the common method is to manually mark lines and then cut according to the markings. However, cutting along the markings can easily lead to cutting deviations due to hand tremors, resulting in errors or material waste. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof sleeve water-stop ring cutting device.

[0005] The gas cutting torch is connected to an oxygen cylinder or liquefied petroleum gas tank via a pipeline. The pipeline also needs to be equipped with a pressure gauge and a control valve, which is existing technology and will not be described in detail here.

[0006] The upright includes a vertical sleeve and a vertical rod inserted into the vertical sleeve. A top plate is fixedly installed at the upper end of the vertical sleeve. An mounting ring is fixedly installed on the vertical sleeve. A spring connects the mounting ring and the top plate. The spring is sleeved on the vertical rod. A magnet is installed at the lower end of the vertical rod.

[0007] The spring is not subjected to external force, and the magnet does not protrude from the base plate.

The end of the outer sleeve is provided with a screw that tightens the inner sleeve rod through a threaded connection. The outer sleeve is mounted on the vertical rod through a rotating ring. Limiting rings are provided on the vertical rod on the upper and lower sides of the rotating ring.

[0009] The cross-sectional shape of the inner sleeve, outer sleeve, vertical rod, and vertical sleeve is rectangular.

[0010] Both the inner sleeve and the outer sleeve have length measurement scale lines on their outer walls, with the smallest scale generally being 1 millimeter.

[0011] The magnet is generally connected to the vertical rod in a detachable manner, such as by screws; in addition, a detachable protective cover can be provided on the outside of the magnet.

[0012] How to use:

[0013] Place the base plate on the steel plate to be cut. Adjust the position of the gas cutting gun according to the outer diameter of the waterstop ring to be cut. After adjustment, tighten the screws to fix it in place. Press the handle, the spring is compressed, and the magnet is attracted to the steel plate.

[0014] Then, press down the handle with one hand and rotate the gas cutting gun along the vertical rod with the other hand to cut the steel plate. After the cutting is completed, the cut round steel plate is removed by a magnet.

[0015] Based on the inner diameter of the waterstop ring plate to be cut, readjust the position of the gas cutting gun, and rotate the gas cutting gun along the vertical rod with the other hand to cut the circular steel plate. After two cuts, the waterstop ring plate is obtained.

[0016] The beneficial effects of the technical solution provided by this utility model embodiment are: it can assist manual cutting of the water-stop ring plate, and the centering of the two cuts is achieved by the magnet, which is not easy to cause deviation; the gas cutting gun can be adjusted in position by the telescopic rod, which is not easy to cause displacement during cutting; the overall structure is simple and easy to use.
