Description

Technical Field

[0001] This invention relates to the field of floor scrubber technology, and more specifically to a liftable side guardrail for a floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying and removing wastewater from the site. It offers advantages such as environmental friendliness, energy efficiency, and high performance. Floor scrubbers are categorized into semi-automatic, fully automatic, walk-behind, and ride-on types.

[0003] Floor scrubbers are equipped with brushes to clean the floor. However, the brushes on both sides of existing floor scrubbers are directly exposed, causing water to be splashed out by the brushes during the cleaning process, making the floor on both sides of the scrubber dirty and resulting in low cleaning efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a liftable side guardrail for a floor scrubber to prevent water from splashing out.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liftable side guardrail for a floor scrubber, comprising a mounting frame and a cover plate, wherein a rubber pad is fixedly connected to the cover plate, and a rotating mechanism is provided on the mounting frame, the rotating mechanism comprising a first rotating part and a second rotating part, wherein the cover plate rotates on a first plane via the first rotating part, and the cover plate rotates on a second plane via the second rotating part, wherein the first plane and the second plane are perpendicular to each other.

[0006] As a further improvement of the present invention, the first rotating part includes a bracket and a rotating shaft, the rotating shaft being fixedly connected to the mounting bracket, and the bracket being rotatably connected to the rotating shaft.

[0007] As a further improvement of the present invention, the second rotating part includes a plurality of positioning rods and a plurality of connecting members, wherein each connecting member corresponds to one of the positioning rods, and a mounting plate is fixedly connected to the cover plate. One end of each connecting member is rotatably connected to the positioning rod, and the other end of each connecting member is rotatably connected to the mounting plate.

[0008] As a further improvement of the present invention, two positioning rods and two connecting members are provided respectively. The two connecting members are parallel to each other, and the vertical distance between the two connecting members is greater than two-fifths of the length of the connecting member and less than one-half of the length of the connecting member.

[0009] As a further improvement of the present invention, a limiting part is provided on the mounting plate, the limiting part being used to restrict the rotation of the cover plate on the second plane.

[0010] As a further improvement of the present invention, the bracket includes a horizontal plate with a through hole, and the limiting part includes a hook that is movably connected to the mounting plate and is adapted to the through hole.

[0011] As a further improvement of the present invention, the mounting bracket includes a fixing member and a support member, the fixing member is fixedly connected to the support member, the rotating shaft is connected to the support member, and the distance between the rotating shaft and the fixing member is less than the vertical distance from the rotating shaft to the through hole and greater than two-thirds of the vertical distance from the rotating shaft to the through hole.

[0012] As a further improvement of the present invention, the top surface of the cover plate is a first inclined surface, the bottom surface of the cover plate is a second inclined surface, the height of the first inclined surface gradually decreases from the end near the mounting frame to the end away from the mounting frame, and the height of the second inclined surface gradually increases from the end near the mounting frame to the end away from the mounting frame.

[0013] As a further improvement of the present invention, the cover plate includes a connecting plate and an arc-shaped member, the arc-shaped member being located at the end of the connecting plate away from the mounting frame, and the vertical distance between the end of the arc-shaped member near the connecting plate and the mounting frame gradually decreasing from the end of the arc-shaped member away from the connecting plate.

[0014] As a further improvement of the present invention, the arc angle of the arc-shaped member is in the range of 10° to 30°.

[0015] The beneficial effects of this invention are as follows: In this invention, the cover plate rotates on a first plane via a first rotating part and on a second plane via a second rotating part, adjusting the distance between the cover plate and the scrubbing brush. This distance adjustment allows water droplets from the brush during the floor cleaning process to be splashed onto the cover plate, changing the distance the water droplets travel. When there is a lot of water on the floor, reducing this distance means the water travels a shorter distance to reach the cover plate, making it easier for the brush to carry it away and clean it, thus speeding up the cleaning process. Furthermore, the distance between the rubber pad and the floor can be adjusted, increasing the pressure between the rubber pad and the floor, thereby reducing water leakage from the rubber pad.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Reference Figure 1 As shown, a floor scrubber with a liftable side guardrail in this embodiment includes a mounting frame 1 and a cover plate 2. The top surface of the cover plate 2 is a first inclined surface, and the bottom surface of the cover plate 2 is a second inclined surface. The height of the first inclined surface gradually decreases from the end near the mounting frame 1 to the end away from the mounting frame 1, while the height of the second inclined surface gradually increases from the end near the mounting frame 1 to the end away from the mounting frame 1. The design of the first and second inclined surfaces reduces the weight of the cover plate 2 at the end away from the mounting frame 1, making the center of gravity of the cover plate 2 closer to the mounting frame 1, thus making the cover plate 2 more stable during rotation in a horizontal or vertical plane. A rubber pad 21 is fixedly connected to the cover plate 2 for contact with the ground. A rotating mechanism 3 is provided on the mounting frame 1, which includes a first rotating part 31 and a second rotating part 32. The cover plate 2 rotates on a first plane through the first rotating part 31. The cover plate 2 rotates on the second plane via the second rotating part 32. With the first plane as the horizontal plane and the second plane as the vertical plane, the rotation of the cover plate 2 on the horizontal plane adjusts the distance between the cover plate 2 and the scrubbing brush. This maximizes the range of distance between the end of the cover plate 2 furthest from the first rotating part 31 and the scrubbing brush. This distance adjustment allows water droplets from the brush to be splashed onto the cover plate 2 during the cleaning process, changing the distance the water travels. When there is a lot of water on the floor, this reduced distance means the water travels less back and forth when it encounters the cover plate 2, making it easier for the brush to carry it away and speeding up the cleaning process. The rotation of the cover plate 2 on the vertical plane adjusts the distance between the rubber pad 21 and the floor, increasing the pressure between the rubber pad 21 and the floor, thereby reducing water leakage from the rubber pad 21. The first and second planes are perpendicular to each other.

[0020] Reference Figure 1As shown, the first rotating part 31 includes a bracket 311 and a rotating shaft 312. The rotating shaft 312 is fixedly connected to the mounting frame 1, and the bracket 311 is rotatably connected to the rotating shaft 312. The rotation of the bracket 311 on the rotating shaft 312 drives the cover plate 2 to rotate in the horizontal direction. The second rotating part 32 includes several positioning rods 321 and several connecting parts 322. The connecting parts 322 correspond one-to-one with the positioning rods 321. A mounting plate 22 is fixedly connected to the cover plate 2. One end of the connecting part 322 is rotatably connected to the positioning rod 321, and the other end of the connecting part 322 is rotatably connected to the mounting plate 22. The cover plate 2 rotates in the vertical plane through the connecting parts 322, so that the cover plate 2 can fall naturally under the action of gravity, so that the rubber pad 21 is in contact with the ground. When needed, there is no need to actively adjust the distance between the cover plate 2 and the ground, which is more convenient. The bracket 311 is provided with a limiting part 4, which is used to restrict the rotation of the cover plate 2 on the second plane. When the floor scrubber is not working, the cover plate 2 is not needed. At this time, the limiting part 4 can be used to restrict the natural fall of the cover plate 2, prevent the rubber pad 21 from sticking to the ground, and prevent the rubber pad 21 from deforming. The bracket 311 includes a horizontal plate 313 with a through hole 314. The limiting part 4 includes a hook 41, which is movably connected to the mounting plate 22. The hook 41 is adapted to the through hole 314. By hooking the hook 41 into the through hole 314, the weight of the cover plate 2 is borne by the bracket 311. The bracket 311 provides support for the cover plate 2, so that the cover plate 2 will not fall naturally.

[0021] Reference Figure 1 As shown, two positioning rods 321 and two connecting pieces 322 are provided. The connecting piece 322 can be a rod, with one end rotatably connected to the positioning rod 321 and the other end rotatably connected to the mounting plate 22. The two connecting pieces 322 are parallel to each other, and the vertical distance between the two connecting pieces 322 is greater than two-fifths of the length of the connecting piece 322 and less than half the length of the connecting piece 322. During the rotation of the cover plate 2 in the vertical plane, the tension on the mounting frame 1 is reduced, the support force provided by the mounting frame 1 is reduced, and damage to the mounting frame 1 is prevented. This ensures that the fixing piece 11 and the support... The support members 12 will not fall apart, extending their service life. The mounting frame 1 includes a fixing member 11 and a support member 12. The fixing member 11 and the support member 12 are fixedly connected. The rotating shaft 312 is connected to the support member 12. The distance between the rotating shaft 312 and the fixing member 11 is less than the vertical distance from the rotating shaft 312 to the through hole 314 and greater than two-thirds of the vertical distance from the rotating shaft 312 to the through hole 314. By limiting the distance between the rotating shaft 312 and the fixing member 11, the range of rotation of the cover plate 2 on the horizontal plane is limited, preventing the cover plate 2 from colliding with the brush plate and affecting the cleaning work of the brush plate.

[0022] Reference Figure 1As shown, the cover plate 2 includes a connecting plate 23 and an arc-shaped component 24. The arc-shaped component 24 is located at the end of the connecting plate 23 away from the mounting bracket 1. The vertical distance between the arc-shaped component 24, from the end near the connecting plate 23 to the end away from the connecting plate 23, and the mounting bracket 1 gradually decreases. The arc-shaped component 24 is adapted to the circular brush disc to prevent water stains from being flung out from the arc-shaped component 24. The arc angle of the arc-shaped component 24 ranges from 10° to 30°, and the angle can be determined according to the different rotation speeds of the brush disc to ensure that water stains are flung out from the arc-shaped component 24.

[0023] Working principle: When the floor scrubber is working, the hook 41 can be removed from the through hole 314. The cover plate 2 falls naturally by gravity and rotates on the first plane and the second plane, so that the rubber pad 21 is in contact with the ground. During the process of the brush cleaning the bottom surface, the water stains on the ground will be splashed onto the cover plate 2 and the rubber pad 21 to prevent the water stains from being splashed out.

[0024] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
