Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, and more specifically to a pipeline cleaning tool. Background Art

[0002] After long-term use of the pipeline, the sewage in the pipeline carries impurities, and some sewage contains grease, which makes the inner wall of the pipeline sticky, causing impurities to adhere to the inner wall of the pipeline. When the pipeline is blocked, it needs to be cleaned.

[0003] The existing cleaning method is mainly high-pressure water gun flushing, which uses high-pressure water sprayed from the water gun to push out impurities. However, for impurities on the inner wall of the pipe, the flushing direction of the water gun cannot be controlled, resulting in impurities on the inner wall cannot be flushed out, resulting in incomplete cleaning. Utility Model Content

[0005] The utility model provides the following technical solution: a pipeline cleaning tool comprises a push rod, a mounting rod is detachably mounted on the top end of the push rod, the top end of the mounting rod is arc-shaped, a mounting block is fixedly connected to the surface of the mounting rod, a groove is provided on the lower surface of the mounting block, a rotating groove is provided on the inner side wall of the groove, a rotating rod is rotatably connected to the inner wall of the rotating groove through a bearing, a connecting block is fixedly connected to the surface of the rotating rod, a fan-shaped scraper is fixedly connected to the surface of the connecting block, and a blocking block is fixedly connected to the lower surface of the mounting block.

[0006] The scheme is further that a circular groove is provided at the top of the push rod, and a connecting rod is fixedly connected to the bottom end of the push rod, the diameter length of the connecting rod is the same as the inner diameter length of the circular groove, and the height of the connecting rod is the same as the depth of the circular groove, the surface of the mounting rod overlaps the inner wall of the circular groove, and the surfaces of the mounting rod and the connecting rod are both provided with a T-shaped mounting groove, and the inner wall of the T-shaped mounting groove is slidably connected with a sliding block, and the sliding block and the opposite surface of the T-shaped mounting groove are fixedly connected with a connecting spring, and a positioning block is fixedly connected with a side of the sliding block away from the connecting spring. A positioning hole adapted for the positioning block is provided on the surface of the push rod, and the upper and lower surfaces of the positioning block are semi-arc-shaped, and the straight surface of the semi-arc surface of the positioning block overlaps the inner wall of the positioning hole, and the arc length of the semi-arc surface of the positioning block is greater than the length of the bottom wall inside the positioning hole. The arrangement of the positioning block, the sliding block and the spring facilitates the connection between the push rods and the connection between the mounting rod and the push rod. The arrangement of the semi-arc surface of the positioning block ensures stability after installation through its plane overlapping the positioning hole.

[0007] A further solution is that the number of the mounting blocks is four, and the four mounting blocks are arranged in a circular array on the surface of the mounting rod, and the four fan-shaped scrapers can cover the surroundings of the inside of the pipe to ensure the raking out of the garbage.

[0008] Technical effects and advantages of the utility model:

[0009] 1. For this pipe cleaning tool, push the installation rod into the pipe. When the fan-shaped scraper encounters garbage obstruction, the fan-shaped scraper will rotate. After pushing the installation rod to a deeper part of the pipe, pull out the installation rod. At this time, the garbage in the pipe will block the return of the fan-shaped scraper. The fan-shaped scraper is subject to resistance. At this time, the fan-shaped scraper opens under the obstruction of the garbage. After opening, the fan-shaped scraper can overlap with the inner wall of the pipe. Continue to pull the installation rod through the push rod. At this time, the fan-shaped scraper can rake out the garbage in the pipe. The impurities on the inner wall of the pipe can be scraped off after multiple treatments, which is convenient for cleaning the pipe.

[0010] 2. For the pipe cleaning tool, press the positioning block, push the straight surface of the positioning block into the T-shaped mounting groove, insert the mounting rod or the connecting rod into the round groove, at this time, the arc surface of the positioning block is forcefully received in the T-shaped mounting groove, after the mounting rod or the connecting rod is completely inserted, rotate the push rod, when the positioning port is rotated to the positioning block, the elastic force of the connecting spring pushes the positioning block to be inserted into the positioning port, at this time, the straight surface of the positioning block moves to the positioning port, which can prevent the positioning block from being pulled out, and when taking out the mounting rod or the connecting rod, press the positioning block to move the arc surface of the positioning block to the positioning port and then pull the push rod, so that the tool can be disassembled and assembled for easy use.
