Abstract
The invention discloses a kind of stair, comprise some ladders, first surface and the second surface angulation of some ladders are more than or equal to 90 degree, each ladder is divided into Part I and Part II according to the plane at the mid point line place of the mid point line of first surface both sides and second surface both sides, Part I and the Part II of each ladder are rotationally connected, run-on point is positioned at first surface mid point, ladder side is provided with head rod, head rod and some Part I hinged, ladder side is provided with motor, on the output shaft of motor, bending is provided with the second connecting rod, second connecting rod is provided with waist hole, head rod one end is slidably connected in waist hole.This stair facilitate people to walk for ladder in the ordinary course of things, and when needs carrying heavy goods, electric machine rotation drives Part I upset, and stair become slide, and weight can be placed in go-cart by people, is carried upstairs by weight easily with go-cart along slide.
Description
Technical field
The present invention relates to a kind of stair, specifically a kind of stair that can realize slide and ladder conversion.
Background technology
In daily life, what the general family of people generally adopted when building stair is all ladder, because ladder is convenient to people's walking.If but when wanting carrying heavy goods, stair-stepping stair just can not use go-cart to carry, necessary manpower lift to move, and quite require great effort in lift to move process.
Summary of the invention
The present invention is directed to prior art deficiency, provide a kind of stair, this stair can realize the conversion of slide and ladder, making stair is generally ladder, can slide be converted to when needs carrying heavy goods, weight can be contained in go-cart and push, convenient carrying.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of stair, comprise some ladders, first surface and the second surface angulation of some described ladders are more than or equal to 90 degree, each described ladder is divided into Part I and Part II according to the plane at the mid point line place of the mid point line of described first surface both sides and described second surface both sides, described Part I and the described Part II of each described ladder are rotationally connected, run-on point is positioned at described first surface mid point, described ladder side is provided with head rod, described head rod and some described Part I hinged, described ladder side is provided with motor, on the output shaft of described motor, bending is provided with the second connecting rod, described second connecting rod is provided with waist hole, described head rod one end is slidably connected in described waist hole.This stair facilitate people to walk for ladder in the ordinary course of things, and when needs carrying heavy goods, electric machine rotation drives described Part I to overturn, and stair become slide, and weight can be placed in go-cart by people, are carried upstairs by weight easily with go-cart along slide.
In technique scheme, preferably, when stair are stepped, described Part I and described Part II contact surface are respectively arranged with fitting projection and groove, due to script Part I and Part II contact surface when Part I is dug as the upper surface of slide, if upper surface friction not, people is easy to slip, and therefore arranges projection and the friction between groove increase slide and people's sole.
The present invention compared with prior art, has following beneficial effect:
This stair of the present invention are in the ordinary course of things for ladder facilitates people to walk, when needs carrying heavy goods, electric machine rotation drives described Part I to overturn, and stair become slide, weight can be placed in go-cart by people, is carried upstairs by weight easily with go-cart along slide.

Fig. 1 is the structural representation of embodiment of the present invention state one.
Fig. 2 is the structural representation of embodiment of the present invention state two.
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 1 to Fig. 3, a kind of stair, comprise some ladders 1, first surface 11 and second surface 12 angulation of some described ladders 1 are more than or equal to 90 degree, each described ladder 1 is divided into Part I 2 and Part II 3 according to the plane at the mid point line place of the mid point line of first surface 11 both sides and described second surface 12 both sides, described Part I 2 and the described Part II 3 of each described ladder 1 are rotationally connected, run-on point is positioned at described first surface 11 mid point, described ladder 1 side is provided with head rod 4, described head rod 4 is hinged with some described Part I 2, described ladder 1 side is provided with motor 5, on the output shaft of described motor 5, bending is provided with the second connecting rod 6, described second connecting rod 6 is provided with waist hole 61, described head rod 4 one end is slidably connected in described waist hole 61.This stair facilitate people to walk for ladder in the ordinary course of things, and when needs carrying heavy goods, motor 5 rotates and drives described Part I 2 to overturn, and stair become slide, and weight can be placed in go-cart by people, is carried upstairs by weight easily with go-cart along slide.
When stair are stepped, described Part I 2 and described Part II 3 contact surface are respectively arranged with fitting projection 21 and groove 31, in the present embodiment, Part I 2 is provided with protruding 21, Part II 3 is provided with groove 31, due to script Part I 2 and Part II 3 contact surface when Part I 2 is dug as the upper surface of slide, if upper surface friction is not, people is easy to slip, therefore arrange protruding 21 and groove 31 increase friction between slide and people's sole.
