DETAILED DESCRIPTION

[0023] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further explained below in combination with the drawings and examples. It should be explained that the examples and features in the examples of the present application can be combined with each other without conflict.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a quick-release structure for the brush plate of a floor scrubber chassis, including a brush plate 1. The brush plate 1 is provided with a quick-release mechanism 4 inside. The quick-release mechanism 4 includes a connecting plate 41. An end platform 45 is fixedly connected to the upper end of the connecting plate 41. An insertion post 46 is fixedly connected to the upper end of the end platform 45. An inner cavity 48 is formed through the insertion post 46, the end platform 45 and the connecting plate 41. A connecting frame 411 is slidably connected to the lower end of the inner cavity 48. A top post 410 is fixedly connected to the middle of the upper end of the connecting frame 411. The top post 410 is slidably connected to the inner cavity 48. Limiting blocks 47 are rotatably connected to both sides of the middle of the upper end of the insertion post 46.

[0026] The specific settings and functions of this embodiment will be described in detail below. By setting the limiting block 47 and the top column 410, during disassembly, the connecting plate 41 can be pushed upward and the top column 410 can be pulled out to disconnect the limiting block 47 from the motor drive shaft 2, thus completing the disassembly. This design makes disassembly relatively simple and does not require flipping or setting up the floor scrubber for easy use. At the same time, after installation, the weight of the quick-release mechanism 4 and the brush plate 1 causes the inner groove 5 to press the limiting block 47, thereby pressing the top column 410 and increasing the connection stability.

[0027] Example 2: Figure 1 - Figure 6 As shown, a bottom arc groove 416 is provided in the middle of the lower end of the limiting block 47, the upper end of the top column 410 is a dome-shaped design, an external groove 44 is provided on the outer edge of the connecting plate 41, a connecting hole 42 is provided through the lower outer edge of the connecting plate 41, a snap-fit ​​bracket 43 is fixedly connected to the upper end of the connecting plate 41, the snap-fit ​​bracket 43 snaps into the brush plate 1, the connecting hole 42 is fixedly connected to the brush plate 1 by a bolt, a lever plate 412 is fixedly connected to the lower end of the connecting bracket 411, and a spring 4 is provided between the connecting bracket 411 and the inner cavity 48. 14. A first slot 413 is provided on the outer surface of the connecting frame 411. A limiting block 49 is fixedly connected inside the inner cavity 48. The first slot 413 and the limiting block 49 are slidably connected. A limiting groove 415 is provided at the outer edge of the lower end of the connecting frame 411. A brush 3 is fixedly connected to the lower end of the brush plate 1. A connecting sleeve 6 is provided inside the brush plate 1. The end plate 45 is inserted into the connecting sleeve 6. A motor drive shaft 2 is provided inside the connecting sleeve 6. An inner groove 5 is provided inside the motor drive shaft 2. A plug 46 is inserted into the inner groove 5.

[0028] The effect achieved by the whole embodiment is that the position of the connecting frame 411 after installation is limited by the setting of the limiting block 49 and the first clamping groove 413 and the limiting groove 415, so as to ensure the stability of the connection and avoid the disconnection of the limiting block 47 and the built-in groove 5 when the scrubber is working, the spring 414 is arranged for extruding the connecting frame 411, so that the top column 410 can be quickly disconnected from the bottom arc groove 416 when disassembling, so as to further increase the disassembling speed, the external groove 44 is arranged to facilitate holding the connecting disc 41 for installation and disassembly, which is convenient to use, the clamping frame 43 is arranged to clamp the connecting disc 41 and the brush disc 1, and pre-installation is carried out, so as to fix the connecting disc 41 and the brush disc 1.

[0029] The use method and working principle of the device are as follows: when disassembling, the brush disc 1 is lifted upwards, then the hand is inserted below the brush disc 1 to push the connecting frame 411 upwards, at this time, the brush disc 1 moves upwards, the connecting disc 41 rotates downwards, the connection between the bottom arc groove 416 and the top column 410 is loosened, the limiting groove 415 is disconnected from the limiting block 49 by rotating the knob 412, until the first clamping groove 413 is connected with the limiting block 49, the connecting frame 411 is popped out by the elastic force of the spring 414, so that the top column 410 is disconnected from the limiting block 47, in this way, the limiting block 47 is disconnected from the built-in groove 5, the brush disc 1 is put down, and the disassembly is completed, then the brush disc 1 is taken out from below the scrubber, and the brush 3 can be cleaned, when installing, the motor drive shaft 2 is inserted into the connecting sleeve 6, at this time, the insertion column 46 is inserted into the built-in groove 5, the connecting frame 411 is pushed upwards, the knob 412 is rotated, until the limiting block 49 is clamped with the limiting groove 415, in this process, the top column 410 pushes the limiting block 47 to rotate, so that the limiting block 47 is connected with the built-in groove 5, the hand is released, the insertion column 46 is pressed downwards by the weight of the brush disc 1, the limiting block 47 is pressed by the built-in groove 5, so that the limiting block 47 presses the top column 410, and the limiting block 47 is always connected with the built-in groove 5.

[0030] The above is only a preferred embodiment of the present application, and is not a limitation on other forms of the present application. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the above embodiments according to the technical essence of the present application shall be within the protection scope of the technical scheme of the present application.
