Preferably, the moving plates are arranged in a concave shape, the opening directions of the two moving plates are opposite, and the moving plates are wrapped by rubber pads.

Preferably, the inner part of the bottom end of the air bag is fixedly connected with a supporting block, and the height of the supporting block is lower than the communication position between the telescopic hose and the air bag.

Compared with the prior art, the invention has the beneficial effects that:

1. the movable plate is used for moving, so that the upper surface and the lower surface of the pedal are cleaned completely by the aid of the spongy cushion, the spongy cushion is only required to be detached from the movable plate and replaced with a new one during cleaning, the pedal is not required to be cleaned by the mop which is stooped one by one every day, time of a user is saved, labor intensity of the user is reduced, and the pedal cleaning machine is more convenient and scientific to use.

2. The purpose of dust removal is further achieved by utilizing static electricity generated by friction, and meanwhile, the opening directions are opposite when the movable plate is installed each time, so that the cleaning effect can be improved, and meanwhile, the side edges of the pedals can be cleaned.

In the figure: the device comprises a supporting side plate 1, a spring 2, an air bag 3, a rubber rod 4, a mounting plate 5, a friction pad 6, a pressure valve 7, an expansion hose 8, a connecting plate 9, a spongy cushion 10, a pedal 11 and a movable plate 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-3, a duplex building stair comprises two supporting side plates 1, a plurality of mounting grooves are arranged on the inner sides of the two supporting side plates 1 at equal intervals, an air bag 3 vertically arranged is mounted at the bottom end of each mounting groove, the side edge of the upper end of the air bag 3 is communicated with the atmosphere, a connecting plate 9 is fixedly connected to the upper end of each air bag 3, a spring 2 is fixedly connected between the connecting plate 9 and the side wall of the mounting groove, a pedal 11 is fixedly connected to one end of the connecting plate 9, a mounting plate 5 is mounted on the connecting plate 9, the mounting plate 5 is arranged in a concave shape, a gas collection cavity is arranged on the side wall of the mounting plate 5, a pressure valve 7 and a one-way valve are mounted in the gas collection cavity, the pressure valve 7 is communicated with the bottom end of the air bag 3 through a flexible hose 8, a supporting block is fixedly connected to the, therefore, the spring 2 is prevented from being damaged due to the fact that the spring 2 exceeds the stiffness coefficient, the friction pad 6 is laid on the inner wall of the mounting plate 5, the movable plates 12 are symmetrically and slidably connected to the pedal 11, the movable plates 12 are arranged in a concave shape, the opening directions of the two movable plates 12 are opposite, the movable plates 12 are wrapped by rubber pads, the sponge pads 10 are installed on the contact surfaces of the movable plates 12 and the pedal 11, the rubber rods 4 are installed on one sides, close to the friction pad 6, of the movable plates 12, and the rubber rods 4 are slidably connected.

In the invention, when a person steps on the pedal 11, the pedal 11 moves downwards under the action of gravity, meanwhile, the spring 2 stretches and the air bag 3 compresses, when the air bag 3 is compressed, the air in the air bag enters the air collecting cavity through the telescopic hose 8, and when the connecting plate 9 has no gravity, the connecting plate 9 and the air bag 3 are reset under the action of the spring 2 for next use;

when going upstairs and downstairs each time, the connecting plate 9 will move downwards, so that the air in the air bag 3 is continuously discharged into the air collecting cavity, the pressure in the air collecting cavity is gradually increased along with the continuous increase of the pressed air, when the limit pressure of the pressure valve 7 is reached and broken through, so that the pressure valve 7 is opened, the air inside is sprayed out instantly under the action of pressure intensity, and then impacts on the rubber rod 4, so that the rubber rod 4 moves towards the middle, the moving plate 12 is driven by the movement of the rubber rod 4 to move, therefore, the upper surface and the lower surface of the pedal 11 are wiped clean by the spongy cushion 10, and the spongy cushion 10 only needs to be detached from the movable plate 12 and replaced by a new one when being cleaned, the pedals 11 do not need to be cleaned by stooping down one by the mop every day, so that the time of a user is saved, the labor intensity of the user is reduced, and the use is more convenient and scientific.

In the moving process of the moving plate 12, the rubber rod 4 and the friction pad 6 generate friction, so that a large amount of static electricity is generated around the rubber rod 4, dust on the upper surface and the lower surface of the pedal 11 can be adsorbed in the moving process of the moving plate 12, the dust removal purpose is further achieved, meanwhile, the opening directions are opposite when the moving plate 12 is installed every time, the cleaning effect can be improved, and meanwhile, the side edge of the pedal 11 can be cleaned.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
