Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] During pipe cleaning, cleaning brushes are often used to remove dirt and impurities from the inner walls of pipes. Traditional cleaning brushes are mostly round in design, and their diameter is usually fixed. While this design can meet the cleaning needs of pipes with a specific diameter, it is not flexible enough when dealing with pipes of different diameters. It cannot adapt to the actual needs of pipes of different sizes. When the diameter of the cleaning brush does not match the diameter of the pipe, not only will the cleaning effect be poor, but it may even be unable to pass through the pipe smoothly, thus failing to complete the cleaning task.

[0022] To resolve the aforementioned defects in the use of the cleaning brush, please refer to [link / reference needed]. Figures 1-4 This utility model provides an installation structure for a variable-diameter arc-shaped cleaning brush, which can adjust the diameter of the cleaning brush according to the diameter of the pipe, making it suitable for pipes of different diameters. The cleaning brush uses a handle 1 as a base, with a support frame 2 fixedly connected to one end of the handle 1. The support frame 2 has multiple circumferentially evenly distributed telescopic grooves 3. Limiting rods 4 are movably installed inside the telescopic grooves 3, and brushes 5 are fixedly connected to one end of the limiting rods 4. An adjustment mechanism 6 is provided on the handle 1 to drive the multiple brushes 5 to expand or contract synchronously. The adjustment mechanism 6 can drive the multiple brushes 5 to expand or contract synchronously, thereby adjusting the diameter of the cleaning brush. The adjustment mechanism 6 includes a turntable 61 rotatably sleeved outside the handle 1. The upper part has multiple arc-shaped limiting grooves 62 corresponding to the expansion groove 3. The other end of the limiting rod 4 passes through the limiting groove 62 and is threaded with an installation piece 63. When adjusting the diameter of the cleaning brush, the turntable 61 is rotated. Due to the action of the limiting groove 62, the limiting rod 4 can be driven to slide along the expansion groove 3, realizing the synchronous expansion and contraction of multiple brushes 5. This makes the cleaning brush suitable for pipes of different diameters. When the cleaning brush has been used for a certain period of time and the brush 5 becomes aged or worn, the brush 5 can be removed and replaced by rotating the installation piece 63. This also facilitates the maintenance of the cleaning brush.

[0023] After the diameter of the cleaning brush is adjusted, the turntable 61 needs to be fixed in order to ensure the stability of the brush 5. Therefore, the handle 1 is provided with an adjusting component 64 for fixing the turntable 61. The adjusting component 64 includes a sleeve 641 fixedly installed on the side of the turntable 61. The sleeve 641 is rotatably sleeved on the outside of the handle 1. One end of the sleeve 641 has a plurality of circumferentially evenly distributed slots 642. The outer wall of the handle 1 is slidably installed with a plug rod 643 that matches the slot 642. When the plug rod 643 is inserted into the slot 642, it can limit the sleeve 641 and restrict the rotation of the turntable 61, thereby fixing the multiple brushes 5 in the designated position and ensuring the stability of the cleaning brush. When adjusting the diameter of the cleaning brush, simply remove the plug rod 643 from the slot 642.

[0024] To facilitate control of the insertion rod 643, a toothed plate 644 is fixedly connected to one side of the insertion rod 643. A rotating shaft 645 is rotatably connected inside the handle 1. One end of the rotating shaft 645 is fixedly connected to a gear 646 that meshes with the toothed plate 644, and the other end of the rotating shaft 645 is fixedly connected to a pressure rod 647. A torsion spring 648 is sleeved on the outside of the rotating shaft 645. The two ends of the torsion spring 648 are respectively fixedly installed on the inner side of the gear 646 and the outer wall of the handle 1. A protruding pressure head 649 is provided at the end of the pressure rod 647. When adjusting the brush 5, the handle 1 is held and the protruding pressure head 649 is pressed. The protruding pressure head 649 facilitates the rotation and downward pressing of the pressure rod 647. The rotation of the pressure rod 647 drives the rotating shaft 645 to rotate, and at the same time, the torsion rod 647 rotates. When spring 648 deforms, the rotating shaft 645 rotates, driving gear 646 to rotate. Gear 646 rotates, causing toothed plate 644 to slide. The sliding of toothed plate 644 causes insert rod 643 to move out of slot 642. The other hand can turn the turntable 61 to control the synchronous expansion and contraction of multiple brushes 5. After adjusting the brushes 5, release the protruding pressure head 649. The rotating shaft 645 can be reversed and reset by the torque of torsion spring 648. The reverse rotation of rotating shaft 645 drives gear 646 to reverse, and gear 646 reverses, causing toothed plate 644 to slide and reset. This allows insert rod 643 to be re-inserted into the corresponding slot 642, and the turntable 61 to be fixed again. The adjustment of brushes 5 is thus completed. The operation is simple and convenient.
