Abstract

Disclosed is a folding ladder, which comprises an upper ladder and a lower ladder hinged with each other, and the free end of the upper ladder is hinged with the wall body of the side face; a traction apparatus connected with the lower ladder is arranged above the upper ladder, the traction apparatus comprises a driving motor, a winding drum and a haulage rope, and one end of the haulage rope is hinged with the lower ladder; and the upper ladder and the lower ladder in initial state are horizontally arranged respectively by folding. The upper ladder and the lower ladder adopt the hinged connection means, in the initial state, the upper ladder and the lower ladder are horizontally arranged at one side of the wall body respectively to form a rather narrow combined state, the storage space is rather small, the structure is simple and the manufacturing cost is low; when needing to extend the ladder, the driving motor runs, the haulage rope is lowered to cause the free end of the lower ladder to swing downwards until reaching the same straight line with the upper ladder, and the operation is simple and convenient; and the driving motor operates inversely to realize the furling state of the upper ladder and the lower ladder, so as to facilitate operation.

Description

Folding ladder

(1) technical field

The utility model relates to a kind of ladder, specifically is a kind of folding ladder of collapsible stretching, extension.

(2) background technology

Existing folding ladder, complex structure, space occupy-place are big, and manufacturing cost height, result of use are poor.

(3) summary of the invention

In order to overcome the defective that above-mentioned technology exists, the utility model provide a kind of simple in structure, result of use good, can make full use of the folding ladder of space and low cost of manufacture.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of folding ladder includes mutually hinged last ladder and descending stair, and the free end of described upward ladder and the body of wall of side are hinged; Described top of going up ladder is provided with the draw-gear that is connected with descending stair, and described draw-gear includes drive motors, reel, pull rope, and an end and the descending stair of described pull rope are hinged; The last ladder and the descending stair of original state, horizontal folding is arranged respectively.

Pull rope is connected by swivel pin with descending stair, and described swivel pin is two, is arranged symmetrically in the descending stair both sides.

The free-ended back of described descending stair is provided with the buffer limit piece.

The beneficial effects of the utility model mainly show: 1, go up ladder, the hinged connected mode of descending stair employing, original state, last ladder and descending stair horizontal arrangement respectively form narrower merging phase in body of wall one side, deposit take up space less, simple in structure, low cost of manufacture; 2, when needs extend, drive motors work, pull rope transfer make the descending stair free end to lower swing until being positioned at same straight line with last ladder, simple, convenient; 3, the drive motors reverse operation can be realized the rounding state of ladder and descending stair, easy operating; 4, the affixed point of pull rope and descending stair has 2, is arranged symmetrically in the both sides of descending stair, steady, safety during traction; 5, the back of descending stair is provided with the buffer limit piece, in the time of avoiding the pull rope tractive to put in place and last terraced collision impact, abates the noise.

(4) description of drawings

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is in the schematic diagram of extended configuration for the utility model.

(5) specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to accompanying drawing 1-2, a kind of folding ladder includes mutually hinged upward ladder 1 and descending stair 2, and the free end of described upward ladder and the body of wall 3 of side are hinged; Described top of going up ladder is provided with the draw-gear that is connected with descending stair, and described draw-gear includes drive motors 4, reel 5, pull rope 6, and pull rope is connected by swivel pin 7 with descending stair, and described swivel pin is two, is arranged symmetrically in the descending stair both sides; The last ladder and the descending stair of original state, horizontal folding is arranged respectively.The free-ended back of described descending stair is provided with buffer limit piece 8.
