Abstract

The invention relates to a ladder, aiming to solve the problem that the ladder in the prior art has a single function. The ladder comprises a primary ladder and a secondary ladder, wherein the upper end of the secondary ladder and the upper end of the primary ladder are in adapter coupling together through a hinge, and a U-shaped groove is formed in each long primary rod; each U-shaped groove consists of a flat plate and two vertical plates perpendicular to the flat plate; primary chutes are formed in the front side and the rear side of each long primary rod; the inner side wall of each vertical plate of each U-shaped groove is provided with a sliding strip, the two sliding strips of each U-shaped groove are respectively arranged in the two primary chutes in each long primary rod; secondary chutes are formed in the front side and the rear side of each long secondary rod; each long primary rod is sleeved by a chuck; and a neck is formed in each primary ladder. The length of the ladder can be changed through bending, the ladder can be used at both higher positions and lower positions, and the problems that an existing ladder is single in function and the use is limited can be solved.

Description

A kind of ladder

Technical field

The present invention relates to a kind of ladder.

Background technology

Current function of ladder is single; The length of vertical ladder is fixed, and can not regulate length, sometimes vertical ladder oversize can not apply with less space in, vertical ladder is too short sometimes can not get too high article; Vertical ladder need to lean on the wall and use, and uses on the ground and can not independently stand; Double ladder can independently be stood and be used on the ground, but double ladder is often too short, can not be in work high above the ground, and use is restricted; If be equipped with two ladders, not only take up room, and cost be high simultaneously.

Summary of the invention

The invention provides a kind of ladder, be intended to solve the single problem of function of ladder in prior art.

In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of ladder, comprise by the parallel female stock in two of left and right and be connected in mother's ladder that the female quarter butt between two female stocks forms, by the parallel sub-stock in two of left and right be connected in the sub-ladder that the sub-quarter butt between two root stocks forms, the upper end of described son ladder is equipped with a U-shaped groove matching with female stock together with transferring by hinge with the upper end of female ladder on every female stock; Each U-shaped groove forms by a flat board with perpendicular to two risers of flat board; The front side of described female stock and rear side are equipped with the female chute that is parallel to female stock, on each riser inside wall of U-shaped groove, are equipped with a draw runner matching with female chute, and two draw runners on U-shaped groove are separately positioned in two female chutes on female stock; Front side and rear side that lock is stated sub-stock are equipped with the sub-chute that is parallel to sub-stock and matches with draw runner; Group ladder and female terraced time in the same plane, sub-chute and female chute are corresponding and communicate one by one; On each female stock, be all socketed with one for limiting the fixture block of U-shaped groove position, each fixture block forms by one U-shaped and one elastica that is connected to U-shaped two ends; On each female ladder, be equipped with and the U-shaped draw-in groove matching, in the time being positioned at draw-in groove for U-shaped, the part of U-shaped is positioned at draw-in groove, and another part is for limiting the position of U-shaped groove and being positioned at outside draw-in groove.

Further, between described female ladder and sub-ladder, be connected with connecting rod, described connecting rod is made up of sub-connecting rod and female connecting rod; The a end switching of described sub-connecting rod is on sub-ladder, and the b end of sub-connecting rod is together with the switching of the c of female connecting rod end; The d end of female connecting rod is transferred on female ladder by dismountable bearing pin; Not only can be used as vertical ladder and use, and can be used as double ladder use.

Further, on described female ladder, be also provided with one for tying down the rope of bearing pin; In the time that bearing pin is plugged on female ladder, will after rope, tie down bearing pin, can prevent that bearing pin from coming off.

Further, the length of described sub-chute is the half of U-shaped slot length, and described female chute length is 1.6 times of U-shaped slot length, the half that described draw-in groove is U-shaped slot length apart from the length of the upper end of female stock; Embrace sub-stock when U-shaped groove half, when second half embraces female stock, fixture block is stuck in draw-in groove, U-shaped groove can be fixed, thus the state of maintenance vertical ladder; Female chute length is 1.6 times of U-shaped slot length, when being convenient to sub-ladder and female ladder and folding, is not blocked by U-shaped groove.

Further, described connecting rod has two and be separately positioned on left side and the right side of son ladder; When ladder more firm during in double ladder state.

Compared with prior art advantage of the present invention is: the present invention can change the length of ladder by bending, all can use in higher position and lower position operation, has solved current function of ladder single and use restricted problem.
