Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts processing technology, and in particular to an internal groove cleaning tool. Background Technology
[0002] Workpieces with grooves, such as valve blocks and cable clamps, have multiple grooves or holes. After processing, these holes and grooves will have some burrs left. These burrs cannot be removed by ultrasonic cleaning machines. Therefore, after processing, burrs are often removed by scraping with a scraper. The scrapers currently used are relatively simple, consisting of a handle and a blade. This tool can only perform scraping operations through the blade body and cannot pick out the burrs (if some burrs stick to the inner wall of the groove during the scraping process, repeated scraping will have an adverse effect on the roughness of the inner wall). In addition, the existing blade body is relatively wide, so it is not suitable for processing burrs on the inner wall of grooves or holes with small diameters. Utility Model Content
[0003] This utility model provides an internal groove cleaning tool to overcome the shortcomings of the prior art and solve the problem of inconvenient removal of burrs on the inner wall of grooves or holes, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: An internal tank cleaning tool includes a pipe fitting, one end of which is connected to a first end cap via an external threaded ring, and the other end of which is connected to a second end cap via an external threaded ring. The first end cap has a rectangular hole. The fitting has a movable column inside, one end of which is connected to an inner column by a thread. A round rod is formed on the inner column and passes through the second end cap. The end of the round rod is bent into an end hook. The other end of the movable column is connected to a threaded column via a threaded connection. An end plate is formed on the outer end of the threaded column, and a scraper is fixed on the end plate. The scraper passes through a rectangular hole.
[0005] Furthermore, an extended tube is formed on the second end cap, and a round rod is inserted inside the extended tube.
[0006] Furthermore, the outer periphery of the pipe fitting is formed with multiple anti-slip grooves.
[0007] Furthermore, the other end of the hook has a pointed conical structure.
[0008] Furthermore, the scraper has a scraper strip formed on it, the width of the scraper strip is smaller than the width of the scraper, one side of the scraper strip is flush with one side of the scraper, the end of the scraper strip has a pointed tip, and the other side of the scraper strip has a blade.
[0009] Furthermore, the pipe fitting has elongated holes arranged symmetrically. The movable column is equipped with a movable rod that passes through an elongated hole. One end of the movable rod is equipped with an end cap, and a first pressure block is movably mounted on one end of the movable rod. A second pressure block is movably mounted on the other end of the movable rod. The end cap and the first pressure block are located at the same end. A spring is sleeved on the movable rod and is located between the end cap and the first pressure block. An L-shaped top piece is hinged to the other end of the movable rod through a hinge shaft. One end of the L-shaped top piece abuts against the outer end of the second pressure block.
[0010] Furthermore, two pairs of pins are fixed at both ends of the outer periphery of the pipe fitting, with each pair of pins inserted into the second pressure block and the first pressure block respectively.
[0011] Furthermore, the end of the L-shaped top piece that contacts the second pressure block has an arc-shaped structure.
[0012] The advantages of the above technical solution are: This utility model, through the setting of an end hook and its pointed conical structural design, makes it easy to pick up or remove burrs, thereby facilitating burr processing.
[0013] This invention improves safety during operation. Its key feature is that when the end hook is used, the entire scraper is located inside the pipe, while when the scraper is used, the end hook is located at one end of the pipe to prevent the protruding round rod from adversely affecting the scraping action.
[0014] This invention prevents the end hook or scraper from moving when in use. When fixed, the pin is inserted into the second pressure block and the first pressure block, thereby preventing the end hook or scraper from moving during use. Attached Figure Description

One end of the pipe fitting 1 is connected to a first end cap 2 by an external threaded ring, and the other end of the pipe fitting 1 is connected to a second end cap 3 by an external threaded ring. A rectangular hole 20 is opened on the first end cap 2.
[0021] The pipe fitting 1 has a movable column 5 inside. One end of the movable column 5 is connected to an inner column by a thread. A round rod 50 is formed on the inner column. The round rod 50 passes through the second end cover 3. The end of the round rod 50 is bent into an end hook 51. The other end of the end hook 51 has a pointed conical structure.
[0022] The other end of the movable column 5 is connected to a threaded column by a thread. An end plate 52 is formed on the outer end of the threaded column. A scraper 53 is fixed on the end plate 52. The scraper 53 passes through the rectangular hole 20. A scraper strip 54 is formed on the scraper 53. The width of the scraper strip 54 is smaller than the width of the scraper 53. One side of the scraper strip 54 is flush with one side of the scraper 53. A tip 55 is formed at the end of the scraper strip 54. A blade is opened on the other side of the scraper strip 54.
[0023] The second end cap 3 has an extended tube 30 formed on it, and the round rod 50 passes through the extended tube 30.
[0024] The pipe fitting 1 has symmetrically arranged elongated holes 10. The movable column 5 has a movable rod 4, which passes through the elongated holes 10. One end of the movable rod 4 is provided with an end cap 42. A first pressure block 41 is movably provided at one end of the movable rod 4.
