[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Disc brushes usually consist of bristles 23, a chassis, and a central shaft. The bristles 23 can be nylon, steel wire, or other materials, while the chassis is usually made of metal or plastic. Depending on the material and hardness of the bristles 23, disc brushes can be divided into soft brushes and hard brushes. Soft brushes are suitable for light cleaning, while hard brushes are used to remove stubborn dirt or for polishing. The diameter and thickness of the disc brush can be customized according to specific application requirements, and common diameters range from a few centimeters to tens of centimeters. In the manufacturing industry, disc brushes are used to clean the surfaces of machinery and equipment, production lines, and workpieces to ensure the hygiene of the production environment and the normal operation of the equipment. Disc brushes are also commonly used in floor cleaning machines, which can effectively remove dirt, oil stains, and other impurities on the ground.

[0025] Example 1:

[0026] Based on the technical defects of the existing technology that are inconvenient to disassemble and assemble, please refer to Figure 1-Figure 5 The utility model provides a disc brush quick-change structure, which can realize the quick-change function of the disc brush by setting a snap assembly 15, has the advantages of convenient and quick disassembly, and greatly improves the replacement efficiency of the disc brush. The quick-change structure includes a mounting disc unit 1 and a disc brush unit 2. The disc brush unit 2 is snapped onto the bottom of the mounting disc unit 1. The mounting disc unit 1 includes a disc body 11. A plurality of limiting plates 17 are integrally formed at a position near the outer edge of the disc body 11. A plurality of equidistantly distributed jacks 14 are opened on the inner side of the disc body 11 near the limiting plate 17, and the inner ends of the jacks 14 are The diameter is smaller than the inner diameter of the middle position of the socket 14, and both sides of the socket 14 are provided with a snap assembly 15 fixed to the surface of the disk body 11, and a limit assembly 18 is also fixed at a position on the surface of the disk body 11 near the snap assembly 15; when installing the disc brush unit 2, the fixing pin 22 is vertically inserted into the socket 14 of the disc body 11, and then the disc body 21 is rotated and the fixing pin 22 enters one end of the socket 14. At this time, the fixing pin 22 is locked under the action of the snap assembly 15 to realize the installation of the disc brush unit 2. Conversely, the disc brush unit 2 can be rotated in the opposite direction when disassembling.

[0027] To facilitate the installation of the brush unit 2, please refer to Figure 2The disc brush unit 2 includes a disc body 21, a through hole is provided at the center of the surface of the disc body 21, and a plurality of equally distributed fixing pins 22 are provided on the outside of the through hole. The fixing pins 22 are inserted into the sockets 14, and bristles 23 are fixed to the bottom of the disc body 21; the fixing pins 22 are inserted into the sockets 14 of the disc body 11, thereby forming a connection with the disc body 21.

[0028] In order to facilitate the connection between the mounting disk unit 1 and the driving shaft of the motor, a connecting column 12 is integrally formed at the center of the surface of the disk body 11, and a steel sleeve 13 is embedded inside the connecting column 12; the steel sleeve 13 can be sleeved on the driving shaft of the motor to achieve the connection between the two, and the connection is stable and not easy to deform.

[0029] To ensure that the motor drive shaft can smoothly drive the mounting disk unit 1 to rotate, the steel sleeve 13 is polygonal and a positioning groove 131 is provided in the steel sleeve 13; the steel sleeve 13 can be positioned and installed on the motor drive shaft through the positioning groove 131, which can ensure the stability of power transmission.

[0030] To achieve the connection and fixation of the fixing pin 22, please refer to Figure 3 The snap assembly 15 includes a fixing block 151 fixed to the surface of the disk body 11, and a mounting groove 1511 is opened on the fixing block 151, and a spring snap 152 is placed in the mounting groove 1511. A bolt 153 is inserted into the fixing block 151, and a nut 154 is threadedly connected to the bottom of the bolt 153. The nut 154 is placed in the perforated groove 16 opened at the bottom of the disk body 11; when the fixing pin 22 enters one end of the insertion hole 14, the fixing pin 22 can be clamped under the action of the spring snap 152 to fix the fixing pin 22, and under the action of the bolt 153 and the nut 154, the spring snap 152 can be easily disassembled and assembled for replacement.

[0031] In order to improve the strength of the disc body 11, a reinforcing rib 19 is provided at the bottom of the disc body 11, and the reinforcing rib 19 is located in the through hole.

[0032] Example 2:

[0033] When the disc brush stops rotating, the disc brush unit 2 will tend to continue rotating under the action of inertia. At this time, the locking force of the spring buckle 152 cannot completely offset its movement trend, which will cause the fixing pin 22 to break away from the spring buckle 152, causing the disc brush unit 2 to fall off. To solve this problem, based on the first embodiment, please refer to Figure 5The limiting assembly 18 includes two connecting blocks 181 fixedly connected to the surface of the disk body 11, and a semi-annular limiting rod 182 is rotatably connected between the two connecting blocks 181; after the fixing pin 22 is clamped by the spring buckle 152, the limiting rod 182 is rotated 90° and clamped to one side of the top of the fixing pin 22. When the mounting disk unit 1 stops rotating, the limiting rod 182 can horizontally limit the movement of the fixing pin 22, thereby avoiding the problem of the fixing pin 22 being detached.

[0034] It can be seen from the above embodiment that when installing the disc brush unit 2, the fixing pin 22 is vertically inserted into the socket 14 of the disc body 11, and then the disc body 21 is rotated to make the fixing pin 22 enter one end of the socket 14. At this time, the fixing pin 22 is locked under the action of the spring clip 152 to achieve the installation of the disc brush unit 2. Conversely, when disassembling, the disc brush unit 2 can be rotated in the opposite direction. After the fixing pin 22 is clamped by the spring clip 152, the limiting rod 182 is rotated 90° and clamped to one side of the top of the fixing pin 22 to achieve the restriction effect on the fixing pin 22. When the installation disc unit 1 stops rotating, the limiting rod 182 can horizontally limit the movement of the fixing pin 22, thereby preventing the fixing pin 22 from detaching.
