In manufacturing, disc brushes are used to clean machinery, production lines, and workpiece surfaces, ensuring a hygienic production environment and proper equipment operation. Disc brushes are also commonly used in floor cleaning machines to effectively remove dirt, oil stains, and other impurities from floors.

[0025] Due to the technical drawbacks of existing technologies, such as inconvenient assembly, please refer to... Figures 1-5 This utility model provides a quick-assembly disc brush structure. The movable sleeve 23 moves due to the elasticity of spring 22. The inner wall of the movable sleeve 23 presses against the self-locking pin 25, forcing one end of the self-locking pin 25 into the self-locking groove 331 on the corner post 33, thus fixing the disc brush in place. No tools are needed for assembly and disassembly, offering the advantages of convenient and quick assembly. The disc brush structure includes a mounting disc assembly 1. A quick-release self-locking assembly 2 is fitted onto the outer wall of the mounting disc assembly 1 and is fixed to the disc brush assembly 3 by engaging the quick-release self-locking assembly 2. The disc brush assembly 3 is inserted into the bottom of the mounting disc assembly 1. During assembly, first lift the movable sleeve 23 in the quick-release self-locking assembly 2 upwards, then insert the corner post 33 in the disc brush assembly 3 along the bottom of the mounting disc assembly 1. Finally, release the movable sleeve 23, and under the action of spring 22, the self-locking pin 25 locks the corner post 33, thus fixing the disc brush in place.

[0026] For easy and quick disassembly and assembly of the disc brush, please refer to... Figure 2The quick-release self-locking assembly 2 includes a fixing ring 21 fixed on the outer wall of the mounting plate assembly 1. The fixing ring 21 is elastically connected to the movable sleeve 23 via a spring 22. The movable sleeve 23 is fitted onto the outer wall of the mounting plate assembly 1. The inner side of the movable sleeve 23 is provided with a self-locking pin 25 movably connected in the mounting plate assembly 1. The self-locking pin 25 is engaged with the top of the disc brush assembly 3. When the disc brush is installed, the corner post 33 on the disc body 31 can be inserted into the mounting plate assembly 1. At this time, the self-locking pin 25 locks the corner post 33, thereby fixing the disc brush. Conversely, by moving the movable sleeve 23 and releasing the self-locking pin 25, the corner post 33 can be pulled out from the bottom of the mounting plate to remove the disc brush.

[0027] To facilitate the installation of the disc brush and ensure smooth power transmission to the drive components, please refer to... Figure 4 and Figure 5 The mounting plate assembly 1 includes a plate body 11, on which a plurality of equally spaced mounting holes 111 are provided. A shaft hole 112 is provided at the center of the plate body 11. The inner wall of the shaft hole 112 is provided with two symmetrically arranged positioning grooves 113. A connecting post 12 is fixedly provided at the bottom of the plate body 11. A plurality of through holes 122 for accommodating self-locking pins 25 are provided on the outer wall of the connecting post 12. The plate body 11 can be installed and fixed to the drive component using the mounting holes 111, and the drive shaft of the drive component can be inserted into the shaft hole 112 to transmit power.

[0028] To prevent the movable sleeve 23 from detaching from the mounting plate assembly 1, a limiting slider 24 is fixed on the inner wall of the movable sleeve 23. The limiting slider 24 is slidably disposed in the limiting groove 121 opened on the outer wall of the connecting column 12. The movable sleeve 23 moves up and down and is limited under the action of the limiting slider 24 and the limiting groove 121, which can prevent the movable sleeve 23 from detaching under the action of the spring force 22.

[0029] To facilitate the movement of the self-locking pin 25, a release groove 231 is provided on the inner wall of the movable sleeve 23 near the bottom. When the disc brush needs to be disassembled, the movable sleeve 23 is lifted upwards, and the release groove 231 can move to the position of the self-locking pin 25. When the corner post 33 is disengaged downwards, the corner post 33 squeezes the movable pin into the release groove 231, so that the corner post 33 can be smoothly pulled out.

[0030] For easier installation of the disk flash, please refer to... Figure 3 The disc brush assembly 3 includes a disc body 31, with bristles 32 fixed at the bottom of the disc body 31 and a corner post 33 fixed at the center of the disc body 31. The corner post 33 is inserted into and adapted to the inner corner groove 123 opened inside the connecting post 12. The outer wall of the corner post 33 is provided with a self-locking groove 331 that engages with the self-locking pin 25. The side wall of the self-locking groove 331 is a sloping structure. The design of the corner post 33 can be used in conjunction with the inner corner groove 123 to provide longitudinal limiting function, making the disc brush more stable and effective when rotating.

[0031] To ensure stable power transmission, both the inner corner groove 123 and the corner post 33 are polygonal structures.

[0032] To improve the strength of the disc brush, a groove is provided on the surface of the disc body 31, and a reinforcing rib 34 is provided in the groove; by setting the reinforcing rib 34, the weight of the disc brush can be reduced, while ensuring the overall strength of the disc brush.

[0033] As can be seen from the above embodiments: When assembling the disc brush, first lift the movable sleeve 23 upwards. At this time, the spring 22 is in a compressed state. Then, insert the corner post 33 from the bottom of the connecting post 12. After the corner post 33 is fully inserted, release the movable sleeve 23 and reset it under the elastic force of the spring 22. At this time, the inner wall of the movable sleeve 23 presses the self-locking pin 25 and forces one end of the self-locking pin 25 into the self-locking groove 331 on the corner post 33, thereby fixing the corner post 33 and completing the installation of the disc brush. When it is necessary to disassemble the disc brush, lift the movable sleeve 23 upwards again. At this time, the release groove 231 can move to the position of the self-locking pin 25. When the corner post 33 is disengaged downwards, the corner post 33 presses the movable pin into the release groove 231, so that the corner post 33 can be smoothly pulled out.
