[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. Floor scrubbers have advantages such as being environmentally friendly, energy-saving, and highly efficient. They are currently mainly used in places such as factories, hospitals, garages, shopping malls, stations, subways, schools, and squares.
[0003] According to CN213097709U, a motor and brush plate connection device for a floor scrubber includes a flange and a magnetic snap-fit plate. The flange has a shaft mounting groove at its center, into which the motor output shaft is inserted to connect to the flange. A metal ring is fixedly installed at the bottom of the flange. The flange and snap-fit plate are connected by magnetic attraction of the metal ring. The materials of the metal ring, flange, and snap-fit plate in the above document result in a relatively heavy overall weight of the brush plate, making it inconvenient for the operator to replace the brush cloth. Furthermore, the small size of the water outlet on the brush plate limits the overall water outlet capacity. Additionally, the centrifugal force generated during high-speed rotation of the brush plate makes it prone to misalignment between the flange and snap-fit plate, limiting the connection stability between them and thus affecting the efficiency of floor cleaning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3 A flange fastening assembly for a floor scrubber cleaning brush includes a flange 1 and a fastening plate 2. The flange 1 has a shaft mounting groove 3 at its center. The shaft mounting groove 3 corresponds to the output shaft on the floor scrubber, thereby locking the flange 1. Further, the flange 1 and the fastening plate 2 are preferably made of PVC rigid plate. The flange 1 and the fastening plate 2 are lightweight and can be installed quickly.
[0021] A ring frame 4 extending into the buckle plate 2 is fixedly installed on flange 1, and five circumferentially distributed positioning strips 5 extending into the buckle plate 2 are fixedly installed on the ring frame 4. The ring frame 4 has a ring-shaped structure, and the buckle plate 2 has circumferentially distributed clamping grooves 6 corresponding to the positioning strips 5. (See the attached instruction manual.) Figure 2 As shown, the positioning strip 5 and the clamp groove 6 work together to quickly lock the flange 1 and the buckle 2. The flange 1 has large circumferentially distributed water outlets, which can ensure the efficiency of cleaning fluid delivery.
[0022] A reinforcing structure is provided between flange 1 and buckle 2.
[0023] The reinforcing structure includes a groove 7 on the buckle plate 2, a cavity 8 on the ring frame 4, and a guide rod 9 fixedly installed in the cavity 8. A slider 10 is slidably sleeved on the guide rod 9, and a spring 12 that cooperates with the guide rod 9 is welded between the slider 10 and the cavity 8. The guide rod 9 guides the slider 10, so that the slider 10 drives the clamp end 11 to move smoothly when it moves. The spring 12 resets the slider 10. When the clamp end 11 is unloaded, the spring 12 can drive the slider 10 back to the initial position.
[0024] The guide rod 9 is horizontally set, the cavity 8 has a concave structure, the clamp end 11 has a U-shaped structure, the spring 12 is sleeved on the guide rod 9, and the clamp end 11, which is connected to the slider 10 and extends into the groove 7, is slidably sleeved in the cavity 8.
[0025] The buckle 2 is provided with a drive structure for driving the clamp end 11.
[0026] The driving structure includes a displacement rod 13 slidably sleeved within the ring frame 4, and a movable frame 14 extending into the clamp end 11 is fixedly installed on the displacement rod 13. A second spring 16 is welded between the displacement rod 13 and the ring frame 4. A contact rod 17 is slidably sleeved on the buckle 2, which moves against the displacement rod 13. A first spring 18 is welded between the contact rod 17 and the buckle 2. Corresponding arc surfaces are opened on the contact rod 17 and the displacement rod 13. After the contact rod 17 moves against the displacement rod 13, the displacement rod 13 causes the movable frame 14 to disconnect from the clamp end 11. The clamp end 11 extends into the groove 7 under the traction of the third spring 12, thereby connecting the flange 1 and the buckle 2. This can prevent misalignment between the flange 1 and the buckle 2 caused by the rotation of the brush plate.
[0027] The displacement rod 13 is set vertically, and two arc grooves 15 are opened in the clamp end 11 to cooperate with the moving frame 14. The position of the clamp end 11 can be locked by the two arc grooves 15. The second spring 16 is set vertically, and the abutment rod 17 is set horizontally on one side of the displacement rod 13. The ring frame 4 is provided with a traction end connected to the displacement rod 13. The traction end can pull the displacement rod 13 and press the clamp end 11 into the cavity 8.
[0028] The functional principle of this utility model can be explained through the following operation methods:
[0029] After the buckle 2 extends onto the flange 1, it automatically locks itself through the cooperation of the positioning strip 5 and the clamp groove 6.
[0030] After the positioning strip 5 and the clamp groove 6 correspond to each other, the contact rod 17 and the displacement rod 13 move against each other under the action of the spring 18. Under the influence of the arc surface, the contact surface between the displacement rod 13 and the contact rod 17 gradually increases, causing the displacement rod 13 to move upward. The spring 16 is stressed, and the upward movement of the displacement rod 13 causes the moving frame 14 to disconnect from the arc groove 15 on the clamp end 11. Under the action of the spring 12, the clamp end 11 drives the slider 10 to slide on the guide rod 9. When the clamp end 11 slides in the cavity 8, it extends into the groove 7, thereby locking the buckle 2 and the flange 1.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
