Abstract
The utility model relates to a folding herringbone ladder which is provided with two ladder faces which are hinged on the upper part of the utility model, wherein the upper part of a ladder face is provided with a hook plate for fixing when the two ladder faces are divided. The upper part of the ladder face on one side is provided with a handrail. The middle part of an articulated shaft is downward articulated with a support rod of which the bottom end is fixed with a foot disc with an enlarged diameter. And thus, gravity is most shared by the support rod when a person climbs the utility model and thus the carrying capacity of the utility model is increased. Bottoms of the ladder faces are provided with non-skid foot margins, and the middle part of the bottom face of each non-skid foot margin is provided with a groove in which a universal wheel is arranged by an elastic piece. When the person climbs the utility model, the ladder faces are stressed, the universal wheel is shrunk into the groove, and the non-skid foot margins touch down to support the gravity; when the person descends from the utility model, the universal wheel is sprung out of the groove under the action of the elastic piece and then the utility model can walk on floors.
Description
Technical field
The utility model relates to a kind of daily necessities, particularly a kind of collapsible double ladder.
Background technology
When being used for interior decoration or depositing, withdrawing the eminence article, especially in the work in library, need often climb up and climb down, put or search books in order, these occasions all need this collapsible double ladder.Collapsible double ladder of the prior art is provided with two treads, and two treads are at upper articulation, and its weak point is: will fix by hook plate when two treads separate.Its bearing capacity is limited.And move inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of novel collapsible double ladder.Its big supporting capacity that improves ladder.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of collapsible double ladder, it is provided with two treads, two treads are at upper articulation, the hook plate of fixing when the top of one of them tread is provided with separately, be characterized in: at the downward hinged support bar in the middle part of jointed shaft, the support bar bottom is fixed with the pin dish of dilated diameter.Like this, in people's cat ladder, the gravity major part is shared by support bar, thereby increases the supporting capacity of ladder.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, in the tread bottom anti-skidding lower margin is housed, and has groove at the middle part, bottom surface of each anti-skidding lower margin, by elastic component universal wheel is housed in the groove.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, on the top of a side tread handrail is housed.
The utility model compared with prior art, the hinged support bar downwards at the jointed shaft of two treads middle part, the support bar bottom is fixed with the pin dish of dilated diameter.Like this, in people's cat ladder, the gravity major part is shared by support bar, thereby increases the supporting capacity of ladder.In the tread bottom anti-skidding lower margin is housed in addition, has groove, by elastic component universal wheel is housed in the groove at the middle part, bottom surface of each anti-skidding lower margin.When at people's cat ladder the time, tread is stressed, and then in the universal wheel retraction groove, anti-skidding lower margin lands, and supports gravity; When the people descended on a ladder, universal wheel ejected groove under the elastic component effect, and then this moment, ladder can be walked on the floor.

Fig. 2 is the mounting structure sketch of universal wheel.
The specific embodiment
A kind of collapsible double ladder, it is provided with 3,6, two treads 3,6 of two treads at upper articulation, the hook plate of fixing when the top of one of them tread 3 is provided with separately 5, at the downward hinged support bar 7 in the middle part of jointed shaft, support bar 7 bottoms are fixed with the pin dish 8 of dilated diameter.Like this, in people's cat ladder, the gravity major part is shared by support bar 7, thereby increases the supporting capacity of ladder.In the tread bottom anti-skidding lower margin 2 is housed, has groove 9, by elastic component 10 universal wheel 1 is housed in the groove 9 at the middle part, bottom surface of each anti-skidding lower margin 2.On the top of a side tread 3 handrail 4 is housed.
