Detailed Description

The technical solutions in the embodiments of the present invention are 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 some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The utility model discloses a garbage bin of ability stair up and down, as shown in fig. 1, fig. 2, fig. 3, including garbage bin body 1, spout 2, supporting rod 3, supporting wheel 4, walking wheel 5, pivot 6, fixed rotating shaft 7, swinging arms 8, activity pivot 9, control rod 10, push rod 11, detent 12, boss 19.

The structure of the garbage can body 1 is the same as that of the existing garbage can, but the front side of the bottom is provided with a boss 19, the rear side is provided with two walking wheels 5, the bottoms of the walking wheels 5 are flush with the bottom surface of the boss 19 on the front side, the garbage can land at four points when being parked, the garbage can is stably placed, and the garbage can be pushed or pulled to walk on the flat ground after being slightly inclined towards the rear side. The upper part of the rear side surface is provided with a push rod 11, and the left side surface and the right side surface are symmetrically provided with an up-down stair device;

the width of a common stair step is 25-35 cm, the sliding grooves 2 are positioned at two sides of the garbage can body 1, the distance from the rear side surface to the rear side surface is half of the width of the stair step, the upper ends of the supporting rods 3 are embedded into the sliding grooves 2 and can only slide up and down in the sliding grooves 2, and the lower ends of the supporting rods 3 are provided with the supporting wheels 4. Because the supporting wheel 4 is positioned right below the chute 2, after the garbage bin is erected, the supporting wheel 4 rotates to travel for a certain distance, and then the traveling wheel 5 can be conveyed to the previous step surface.

The whole operating lever 10 is in a reversed U shape, two sides are side levers, the front ends of the side levers are hinged with the upper end of the supporting rod 3 through a rotating shaft 6, the back of the hinge point is connected with a swinging rod 8 through a movable rotating shaft 9, the other end of the swinging rod 8 is connected with a fixed rotating shaft 7, and the fixed rotating shaft 7 is positioned at the rear edge of the side surface of the garbage can body 1; when the operating lever 10 is pulled up and down, the rotating shaft 6 drives the supporting rod 3 to slide up and down in the chute 2 by taking the movable rotating shaft 9 as a fulcrum, so that the supporting wheel 4 moves up and down, at the moment, the swinging rod 8 swings in a smaller amplitude by taking the fixed rotating shaft 7 as an axis, the side lever of the operating lever 10 is a lever, the movable rotating shaft 9 is a movable fulcrum, and the supporting rod 3 can slide up and down at a vertical position by swinging of the swinging rod 8.

As shown in figure 2, the supporting wheel 4 comprises a pin shaft 15 on which a one-way bearing 14 is arranged, wherein the inner ring of the one-way bearing 14 is integrated with the pin shaft 15, and the outer ring is fixedly connected with a rubber ring 13.

The stop device 12 is installed on the outer side protrusion of the lower end of the supporting rod 3, as shown in fig. 2 and fig. 3, when the garbage can goes upstairs and downstairs, the most important safety problem is that it is generally laborious to go upstairs, when the push rod 11 and the swing control lever 10 are pulled to go upstairs, in order to prevent the supporting wheel 4 from sliding down the stairs due to hand loss, the stop device 12 is installed on the supporting wheel 4, the one-way bearing 14 is installed in the supporting wheel 4, the inner ring of the one-way bearing 14 is integrated with the pin shaft 15, the outer ring is fixedly connected with the rubber ring 13, when the garbage can go upstairs, the handle of the positioning pin 16 is placed in the groove of the upstairs position 17, so that the pin shaft 15 is fixed by the positioning pin 16 and cannot rotate, but the one-way bearing 14 can also rotate in one direction, when the push rod.

The working process is divided into two cases:

1. garbage can upstairs

Firstly, a positioning pin 16 is arranged in a groove of an upstairs position 17 of a stopping device 12, an operator pulls a cart to the edge of a stair, when a walking wheel 5 is in contact with a step, one hand pulls an operating rod 10 upwards, and the other hand slightly presses a push rod 11 downwards, under the action of lever force, a movable rotating shaft 9 is used as a fulcrum, a rotating shaft 6 presses a supporting rod 3 to slide downwards along a chute 2, a supporting wheel 4 moves downwards to support a garbage can, when the bottom of the walking wheel 5 is equal to the height of the last step surface, the push rod 11 is pulled, the supporting wheel 4 rotates to pull the garbage can to the step, then the operating rod 10 is moved downwards, and the supporting wheel 4 is folded upwards by the operating rod 10; the garbage can is continuously pulled forwards, when the travelling wheels 5 knock over the step again, the supporting wheels are approximately positioned in the middle of the width of the step, and the actions are repeated until the garbage can is pulled upstairs.

2. Garbage can stair

The positioning pin 16 is arranged at a downstairs position 18 of the stopping device 12, when the garbage can is pushed to downstairs, the walking wheel 5 is positioned at the edge of a stair step, the operating rod 10 is pulled upwards, the supporting wheel 4 moves downwards to reach the surface of the next step, the garbage can is pushed forwards, when the supporting wheel 4 rotates to move to the middle position of the width direction of the next step, the operating rod 10 is loosened, the supporting wheel 4 is folded upwards, the walking wheel 5 falls onto the step, and the garbage can be stably downstairs by repeating the operation.

When the power arm of the control lever 10 is long, so that the garbage can be controlled without large effort no matter going upstairs or downstairs, the middle part of the garbage can be used for resting, the labor is saved compared with the method of directly carrying the garbage can upstairs and downstairs, when the garbage can is not used, the control lever is put down, the supporting wheel 4 can be automatically lifted, and the influence on the flat ground on pushing the garbage can to walk is avoided.

A garbage can capable of going up and down stairs can be used for climbing stairs, the garbage can move on a road and often bumps down the road with steps, and the garbage can smoothly pass through the road when the garbage can is used.

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 changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
