Description

But outdoor stair of self-cleaning tread

Technical Field

The invention relates to the technical field of building decoration, in particular to an outdoor stair capable of automatically cleaning a stair surface.

Background

The stair is a common structure in the building field, is mainly used for high-rise building's use, makes things convenient for people to climb according to the structure of stair self and reaches the eminence, before the stair becomes the building, it embodies a harmonious powerful symbolic factor, and present stair type has a lot of, has the interior stair also to have outdoor stair.

General outdoor stair mainly used independent building, also have the existence of its shortcoming in the time of the convenience, outdoor stair distinguish in the shelter from that the stair has the roof, can not suffer from the wind-blown sunshine, and the design of outdoor stair self leads to can receiving external environment's influence, sometimes has the accumulation of a lot of dust or debris on the surface of stair, and old man or child lead to going up the special difficultly of stair because the altitude problem of guardrail when the climbing moreover.

In order to solve the problems, the inventor provides the outdoor stair capable of automatically cleaning the stair surface, the stair surface is pressed downwards by a person through the cooperation of the stair surface and the spring, the fan at the bottom of the guardrail is driven to run through the setting of the rack and the gear, dust or sundries on the stair surface can be cleaned, the effect of automatically cleaning the stair surface is achieved, the height of the guardrail can be reduced through the movable connection of the guardrail cross rod and the vertical rod, and the effect of facilitating climbing of old people or children is achieved.

Disclosure of Invention

In order to achieve the purpose, the invention is realized by the following technical scheme: an outdoor stair capable of automatically cleaning stair surfaces comprises handrails, wherein the bottoms of the handrails are fixedly connected with vertical rods, the bottom of the vertical rod is movably connected with a movable clamp, one end of the movable clamp far away from the vertical rod is fixedly connected with a protective cover, the bottom of the protective cover is fixedly connected with a foundation, the top of the foundation is fixedly connected with a connecting plate, the top of the connection plate is fixedly connected with a spring, the top of the spring is fixedly connected with a pedal, the pedal is fixedly connected with a fixed rod at one end close to the protective cover, the fixed rod is fixedly connected with a rack at one end far away from the pedal, a gear is meshed at the outer side of the rack, a rotating rod is fixedly connected inside the gear, an axial column is fixedly connected at one end of the rotating rod far away from the gear, the fan blades are fixedly connected to the outer side of the axle center column, and the cross rod is movably connected to the outer side of the vertical rod.

Preferably, there is the contained angle between handrail and the ground, and is in a parallel position with the ground, guarantees to climb at the in-process of climbing, can will pacify all the time as one borrow power point and climb, and the length of handrail is greater than the distance between two farthest montants.

Preferably, the montant respectively has four with the quantity that removes to press from both sides, and every removes the distance between the clamp and equals, evenly distributed is at the top of protection casing, the quantity of horizontal pole is four, and the clearance distance between every horizontal pole is the same, thereby can remove horizontal pole and montant through the handrail and reduce the height of handrail, makes things convenient for old man and child's climbing.

Preferably, nine springs of bottom fixed connection of footboard, the distance between every spring equals, and the setting of a plurality of springs, the pressure that receives of sharing that can be fine, great extension the life of spring, and have the clearance between footboard and the protection casing, and also not contact between the upper portion of and the connection board.

Preferably, the length of rack is less than the recess length of protection casing, and the contained angle between rack and the dead lever is 90, makes the rack remain vertical direction's motion throughout, and the dead lever is in the position of the lower half part district of rack, contactless between protection casing and the rack prevents that the rack from blocking at the in-process of operation.

Preferably, the length of rotating rod is less than the length of fixed rod, and the quantity of flabellum has two, and the symmetric distribution is at the both ends of axle center post, and the position of flabellum in the recess of protection casing, guarantees that the flabellum can not touch the fixed rod at rotatory in-process.

Preferably, there is the clearance between flabellum and the dead lever, prevents the collision of flabellum and dead lever, leads to going back along with of flabellum, the rack is the flat slide bar in the position at both ends.

The invention provides an outdoor stair capable of automatically cleaning stair surfaces. The method has the following beneficial effects:

1. this but outdoor stair of self-cleaning tread receives the effect in lining through the footboard, and extrusion spring moves down, and footboard moves down drives the dead lever and moves down, and rethread dead lever top rack uses with the cooperation of gear, and it is rotatory to drive the gear, and the rotatory flabellum that drives of gear begins to rotate, has reached the effect that can self-cleaning tread.

2. This but outdoor stair of self-cleaning tread uses through the cooperation that the removal of montant and bottom was pressed from both sides, when promoting the handrail, drives the montant and begins to remove, and the swing joint of rethread montant and horizontal pole, the montant can drive the horizontal pole and remove together, so when promoting the handrail, can carry out the removal of controlling with whole and reduce the height of handrail, has reached the climbing that makes things convenient for old man and child.
