The sleeve is hollow inside and is integrally sleeved and fixed in the end part of one end of the sliding guide pipe; the wall body inside the sleeve is shrunk towards the direction of a central line to form salient point structures which are mutually spaced; and the rubber sleeve is integrally sleeved outside the sliding guide pipe. According to the technical scheme, the dredging machine with sundries attached to the flexible shaft is designed.

Description

Technical Field

[0001] This utility model relates to a drain cleaning machine, which has a unique sleeve structure placed inside the flexible shaft guide tube, so that when the flexible shaft passes through the sleeve, it will clean the debris on the flexible shaft. Background Technology

[0002] A drain cleaning machine is a specialized piece of equipment used for unclogging pipes. It uses a continuously rotating flexible shaft to impact the pipe wall. Currently, during use, debris often adheres to the flexible shaft, affecting its rotation. The main way to deal with this problem is to remove the debris manually, which requires stopping the machine and affects the overall use of the drain cleaning machine. Utility Model Content

[0003] The purpose of this utility model is to provide a drain cleaning machine that facilitates cleaning of flexible shafts. The technical problem to be solved is: to design a drain cleaning machine that removes debris adhering to the flexible shaft.

[0004] A drain cleaning machine that facilitates flexible shaft cleaning includes a sleeve, a rubber sleeve, and a sliding guide tube; the sleeve is hollow inside and is integrally fixed inside one end of the sliding guide tube, and the inner wall of the sleeve contracts towards the center line to form an intermittent protrusion structure; the rubber sleeve is integrally fitted onto the outside of the sliding guide tube.

[0005] The sleeve is a hollow ring structure, and its outer wall is tightly fitted with the inner wall of the sliding guide tube.

[0006] The interspersed protrusions form a plum blossom shape.

[0007] The sliding conduit also has a clamping connector, through which the sliding conduit is assembled with a flexible shaft conduit.

[0008] The clamping connector includes a clamping sleeve and a clamping wrench; the clamping wrench presses the clamping sleeve to fix the sliding guide tube and the flexible shaft guide tube to each other.

[0009] The beneficial effects of this utility model are as follows: By adding a sleeve inside the sliding guide tube, and designing multiple protrusions inside the sleeve, the protrusions are used to block and sweep away debris, preventing it from being brought into the machine and thus ensuring the normal operation of the machine. By designing a clamping connector, the sliding guide tube and the flexible shaft guide tube can be connected together by clamping, allowing the overall length of the two guide tubes to be adjusted as needed to meet the requirements of different applications.

[0019] Please refer to Figures 1 to 2 The figure shows a drain cleaning machine that facilitates the cleaning of a flexible shaft. It mainly includes a body 6, a flexible shaft guide tube 5, a clamping connector 4, a sliding guide tube 3, a rubber sleeve 2, and a sleeve 1. The core innovation of this case is to place a sleeve 1 inside the sliding guide tube 3. The sleeve 1 utilizes the protrusion 11 structure designed inside it to remove debris attached to the flexible shaft.

[0020] The body 6 in the figure is a conventional existing body 6. For specific structure references, see patent publication number CN219033427U, entitled "A Telescopic Adapter Device for a Drain Cleaning Machine," or patent publication number CN219033428U, entitled "An Adapter Device for a Drain Cleaning Machine." The aforementioned body 6 structure extends or retracts the flexible shaft under the action of a motor.

[0021] The sliding conduit 3 in the figure has an inverted J-shaped structure and remains hollow inside, which facilitates the insertion of the sleeve 1 and the penetration of the flexible shaft.

[0022] In the figure, the rubber sleeve 2 is completely wrapped around the outer wall of the sliding conduit 3 to protect the sliding conduit 3.

[0023] The sleeve 1 in the figure is a hollow circular ring structure, which is internally fixed to the end opening of the sliding guide tube 3 by conventional methods such as interference fit, snap fasteners, or screws, thereby maintaining a tight fit with the sliding guide tube 3. The inner wall of the sleeve 1 tapers inward at intervals towards the center line to form a structure of intermittent protrusions 11. These protrusions 11 can be continuous or discontinuous, such as forming a quincunx pattern or other structures. In practical applications, the above-mentioned protrusion structure 11 can also adopt other protruding structures, as long as they can block and catch debris on the flexible shaft.

[0024] In the diagram, the clamping connector 4 is fitted onto one end of the sliding conduit 3 and simultaneously connected to the flexible shaft conduit 5. This allows the sliding conduit 3 to clamp the flexible shaft conduit 5 via the clamping connector 4. The clamping connector 4 is a conventional component, designed with a clamping sleeve 41 and a clamping wrench 42. The clamping sleeve 41 has an internally hollow structure, and the clamping wrench 42 has a conventional arc-shaped structure. With this design, the clamping wrench 42 can press the clamping sleeve 41 to clamp and fix the sliding conduit 3 and the flexible shaft conduit 5.

[0025] The specific embodiments described above are merely illustrative of the present technical solution and are not intended to limit the present technical solution. In the description of the present technical solution, it should be noted that terms such as "upper" and "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
