Description
Technical field
The present invention relates to life applied technical field, be specifically related to a kind of folding mobile stairway.
Background technology
Ladder is daily life tools, even if in high-tech modern society, ladder still has irreplaceable status.But along with the development of society, the progress of human society, the pursuit of people is also more and more higher, and on the basis of practicality, convenience, multifunction and appearance seem very important too.But the ladder on existing market has public feature, that be exactly performance single, take up room larger, and it is heavier, seem extremely inconvenient, be difficult to meet the requirement of modern society people to multifunctionality, convenience, aesthetic property, and our design is just in order to this demand of consumer better, the basis of original ladder is improved, makes its multifunction, convenient purification, attractive in appearanceization.
In daily life, although the purposes of ladder constantly develops to various aspects, ladder all will be used in upper roof, repair wires, stringing etc., even speedily carries out rescue work in fire-fighting, the place such as oil tank sampling also will use ladder.In order to meet these demands, present market there is various ladder.But these ladders have a kind of feature, that takes up room larger exactly, and heavier, seems extremely inconvenient, and the carrying of ladder is just very hard, is difficult to meet the frequent mobile ladder of those needs with the requirement of the staff finished the work.
Prior art can not meet the needs of people, and for making up prior art deficiency, the present invention aims to provide a kind of A type folding mobile stairway.
For achieving the above object, the present invention is by the following technical solutions:
A kind of A type folding mobile stairway, at least comprises front-wheel, the first revolute pair, the second revolute pair, the 3rd revolute pair, the 4th revolute pair, the first support bar, the second support bar, the 3rd support bar, the 4th support bar, trailing wheel, chain, handwheel and gripper shoe; Described front-wheel is symmetricly set on the first both sides, support bar bottom; Described first support bar, the second support bar, the 3rd support bar and the 4th support bar junction are connected with the 4th revolute pair respectively by the first revolute pair, the second revolute pair, the 3rd revolute pair; Described handwheel one end is fixed on support bar, and is connected with trailing wheel by two-stage transmission mechanism by chain; Described gripper shoe is arranged on support bar.
Described first support bar, the second support bar, the 3rd support bar and the 4th support bar junction are rotational structure respectively by the first revolute pair, the second revolute pair, the 3rd revolute pair and the 4th revolute pair junction.
Compared with prior art, the invention has the beneficial effects as follows: this folding mobile stairway,
(1) can use as vertical ladder and double ladder;
(2) there is folder function, take up room after folding less;
(3) removable during work, avoid the trouble of continuous ladder up and down during work, decrease the working time;
(4) can haul away as drawing case after folding, facilitating the carrying of ladder;
(5) low cost, outward appearance is generous, can popularization strong.
Because the design has catered to, consumers in general are convenient, multi-functional, attractive in appearance to the consumer goods, take up space little demand, has no lack of the practicality of works simultaneously, and make also relatively simple, and cost of manufacture is lower.Therefore, product is extensively by the favor of customer; Overall structure is simple, practical, easily manufactured, is easy to promote the use of.
Summary of the invention
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Wherein: 1, front-wheel, the 21, first revolute pair, the 22, second revolute pair, the 23, the 3rd revolute pair, the 24, the 4th revolute pair, 31, the first support bar, the 32, second support bar, the 33, the 3rd support bar, the 34, the 4th support bar, 4, trailing wheel, 5, chain, 6, handwheel, 7, gripper shoe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of A type folding mobile stairway, at least comprises front-wheel 1, first revolute pair 21, second revolute pair 22, the 3rd revolute pair 23, the 4th revolute pair 24, first support bar 31, second support bar 32, the 3rd support bar 33, the 4th support bar 34, trailing wheel 4, chain 5, handwheel 6 and gripper shoe 7; Described front-wheel 1 is symmetricly set on the first both sides, support bar 31 bottom; Described first support bar 31, second support bar 32, the 3rd support bar 33 are connected with the 4th revolute pair 24 respectively by the first revolute pair 21, second revolute pair 22, the 3rd revolute pair 23 with the 4th support bar 34 junction; Described handwheel 6 one end is fixed on support bar, and is connected with trailing wheel 4 by two-stage transmission mechanism by chain 5; Described gripper shoe 7 is arranged on support bar.
Described first support bar 31, second support bar 32, the 3rd support bar 33 and the 4th support bar 34 junction are rotational structure respectively by the first revolute pair 21, second revolute pair 22, the 3rd revolute pair 23 and the 4th revolute pair 24 junction.
The present invention is when making: the agent structure of the design continues to use the framework of double ladder, ensure that stability, outward appearance generous; Adopt 75 degree, optimal climbing angle, often joint is highly 280mm, makes people climb ladder or stand in ladder to work all very comfortable; The foldover design of four joints, the space accounted for after making ladder collapses is less; Handwheel adopts drawing type self-locking, ensure that the safety of user while being user-friendly to; Chain conveyer is nonelastic slip and skidding, reliable operation, efficiency is high, and transmitted power is large, and overload capacity is strong; Can, as drawing case to walk in tow, make ladder use as vertical ladder, and ladder can not from line slip after ladder collapses is considered in the design of wheel simultaneously.
The principle of work and power of the present invention is:
To ascend a height function:
As Household ladder, the function of double ladder is enough to the demand of satisfied most of family.Certainly, sometimes use vertical ladder can be more convenient.The design not only can use as double ladder, also can use as vertical ladder.After being opened completely by ladder, by the self-locking of handwheel, ladder does not just have any difference with common double ladder.While secondary ladder part is packed up, pin is propped up and puts down, by pin support ladder, and can use as vertical ladder.
Locomotive function:
Four wheels adds that Chain conveyer constitutes the mobile system of this design.Through double stage chain wheel deceleration transmission from handwheel to driving wheel, add rotating torque.Handwheel is provided with the safety that drawing self-locking mechanism ensure that ladder movement process.After folding, driven pulley is positioned at ladder side.Can walk by ladder in tow during carrying ladder.
Folder function:
Consider that present domestic space is more and more less, the main ladder and pair ladder of ladder have installed folding joint, respectively when not using by ladder collapses.
