Referring to fig. 1, the stair convenient for cleaning dust in a crack comprises a plurality of L-shaped supporting plates 1 which are sequentially and fixedly connected end to end, wherein an extrusion block 2 is arranged at the top of each L-shaped supporting plate 1, a sliding opening corresponding to the extrusion block 2 is formed in the top of each L-shaped supporting plate 1, a connecting block 3 is fixedly connected onto each extrusion block 2, a movable groove corresponding to the connecting block 3 is formed in the bottom of each L-shaped supporting plate 1 positioned at the top of the connecting block 3, and connecting rods 4 are fixedly connected to two sides of each connecting block 3;
it should be noted that: the stairs are formed by a plurality of L-shaped supporting plates 1 which are fixedly connected end to end in sequence, so that two sides of each L-shaped supporting plate 1 are fixedly connected with the wall surface of a building, the stability of each L-shaped supporting plate 1 is ensured, and the stairs are convenient to use by people; the extrusion block 2 can be limited under the action of the sliding opening, so that the extrusion block 2 can stably move back and forth; the movement of the extrusion block 2 can drive the connection block 3 to move in the movable groove, thereby facilitating the cleaning of people;
further, when people cleared up the crack department of stair with the broom, at first make connecting block 3 forward motion through extrusion piece 2 to be convenient for drive the motion of the connecting rod 4 of connecting block 3 both sides, then the operation after being convenient for, wherein will extrude the piece 2 setting and have following effect at the top of L type backup pad 1: when people clear up one of the L-shaped supporting plates 1, people certainly stand on the lower L-shaped supporting plate 1 of the L-shaped supporting plate 1 to be cleared up, so that people only need to use the toe of one foot to extrude the extruding block 2 on the lower layer, the connecting block 3 can be driven to move in the movable groove, the standing posture and the operation process of people during operation are met, and the use of people is very convenient.
One end, far away from the connecting block 3, of one connecting rod 4 is fixedly connected with a sealing block 8, the bottom of an L-shaped supporting plate 1 is provided with a control cavity corresponding to the sealing block 8, an L-shaped mounting groove is formed in a crack of the L-shaped supporting plate 1, a rubber layer 9 is fixedly connected to the inner side wall of the mounting groove, a plenum chamber 10 is formed between the rubber layer 9 and the inner side wall of the mounting groove, and the plenum chamber 10 is communicated with the control cavity through a plurality of vent holes 11;
it should be noted that: 1. the joint of the outer side wall of the rubber layer 9 and the mounting groove and the outer side wall of the L-shaped support plate 1 are positioned on the same horizontal plane, so that the rubber layer 9 and the L-shaped support plate 1 can be positioned on the same plane, and no crack exists between the joint of the L-shaped support plate 1 and the rubber layer 9, so that dust cannot be accumulated, 2, the rubber layer 9 has the advantage of good plasticity, has certain ductility, and can be guaranteed not to be damaged after being used for a long time; 3. the sealing block 8 is connected with the inner side wall of the control cavity in a sliding and sealing mode, namely the first rubber can be fixedly connected with the outer side wall of the sealing block 8, the sealing performance of the first rubber is guaranteed, the air pressure in the control cavity and the air charging chamber 10 can be changed along with the movement of the sealing block 8, the rubber layer 9 can be conveniently inflated to bulge, and therefore people can conveniently clean the crack of the L-shaped supporting plate 1;
further, when the extrusion block 2 moves forward, the connection block 3 is driven to move forward, so that the sealing block 8 moves forward through the connection rod 4, the volume in the control cavity communicated with the inflation chamber 10 and the inflation chamber 10 is reduced along with the forward movement of the sealing block 8, the air pressure in the inflation chamber 10 and the control cavity is increased, the air pressure in the inflation chamber 10 and the control cavity is in a negative pressure state, so that the rubber layer 9 is adsorbed on the L-shaped support plate 1 when not in use, the air pressure in the inflation chamber 10 and the control cavity is continuously increased along with the forward movement of the sealing block 8 until the air pressure is larger than the external atmospheric pressure, so that the rubber layer 9 is supported, the state can be referred to fig. 2, so that the dust at the seam of the L-shaped support plate 1 slides onto the L-shaped support plate 1 along with the radian of the supported rubber layer 9, and meanwhile, dust which is difficult to clean can be swept onto the L-shaped support plate 1 through the broom, this facilitates the subsequent sweeping of dust from the L-shaped support plate 1.
One end of the other connecting rod 4, which is far away from the connecting block 3, is fixedly connected with a piston 5, the bottom of the L-shaped supporting plate 1 is provided with a cavity corresponding to the piston 5, the cavity is divided into a first control chamber 6 and a second control chamber 7 by the piston 5, and the piston 5 is in sliding sealing connection with the inner side wall of the cavity;
it should be noted that: the connecting rod 4 is connected with the inner side wall of the cavity in a sliding and sealing manner, namely, the outer side wall of the connecting rod 4 is fixedly connected with second rubber, and the inner side wall of the cavity and the inner side wall of the opening corresponding to the connecting rod 4 are fixedly connected with an O-shaped ring, so that the gas in the first control chamber 6 cannot overflow; the piston 5 is in sliding seal with the inner side wall of the cavity, namely, the outer side wall of the piston 5 is fixedly connected with third rubber, so that the influence of gas permeation in the first control chamber 6 and the second control chamber 7 on the change of the gas pressure in the first control chamber 6 and the second control chamber 7 is avoided;
further, when the extrusion piece 2 drives the connecting block 3 and moves forward, drive piston 5 through connecting rod 4 and move forward, then lead to the volume of first control chamber 6 to diminish, and the volume grow of second control chamber 7, lead to first control chamber 6 to be greater than the atmospheric pressure in the second control chamber 7 like this, thereby after finishing using, because first control chamber 6 is greater than the atmospheric pressure in the second control chamber 7, make connecting block 3 reset, and then make the better completion of sealed piece 8 and extrusion piece 2 reset, be convenient for next use.
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.
