Abstract
The utility model relates to a width adjustable foot ladder. The foot ladder comprises a straight ladder, wherein two hollow foot bars are stacked on the upper part of a ladder rod of the straight ladder; a horizontal extension support rod, which can be used as an upper support of the straight ladder after being laterally pulled out from the inner side of each hollow foot bar to be locked, is sleeved with each hollow foot bar; two hollow reinforcing tubes are arranged at the lower part of the ladder rod of the straight ladder in an X-shaped intersection manner; an inclined extension support rod, which can be used as a bottom support of the straight ladder after being pulled out downwards from the inside of each hollow reinforcing tube in an inclined manner, is sleeved with each hollow reinforcing tube. According to the foot ladder disclosed by the utility model, the horizontal extension support rod, which can be used as the upper support of the straight ladder after being laterally pulled out from the inner side of each hollow foot bar to be locked, is sleeved with each of the two hollow foot bars stacked on the upper part of the ladder rod of the straight ladder, and the two hollow reinforcing tubes, which are arranged at the lower part of the ladder rod of the straight ladder in an X-shaped intersection manner, are respectively internally provided with the inclined extension support rod, which can be used as the bottom support of the straight ladder after being pulled out downwards in an inclined manner to be fixed, in a sleeved manner, so that the ladder can adapt to a place with an uneven floor or can be used as usual in a place with holes in the leaning surface.
Description
Technical field
The utility model belongs to ladder technical field, is specifically related to a kind of adjustable wide foot of ladder.
Background technology
Vertical ladder is as the one of ladder, producing, in life, application is very extensive, but common vertical ladder in use, running into while needing there is cavity on the metope that leans on or supporting surface, cannot lean on well support, in addition, in the time running into ground support and be step or sloping floor, the foot of ladder of terraced bar can not be brought into play supporting role well, sometimes, can cause and cannot use vertical ladder, need to fulfil assignment by other instrument, the effect of vertical ladder cannot be given full play to.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above and a kind of adjustable wide foot of ladder that can have empty place to use at ground injustice, leading surface is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of adjustable wide foot of ladder, comprise a vertical ladder, the terraced bar top of described vertical ladder is folded and is provided with two hollow treadles, described in each, in hollow treadle, be arranged with one can be in described hollow treadle after pull-out locking laterally as the horizontal expansion support bar of described vertical ladder upper support, the terraced bar bottom X-shaped of described vertical ladder intersects and is provided with two hollow reinforced pipes, described in each, in hollow reinforced pipe, be arranged with one can be in described hollow reinforced pipe the oblique extension support bar as described vertical ladder bottom support after oblique lower pull-out locking.
The outer end of described horizontal expansion support bar is provided with Anti-slip cover.
The bottom of described oblique extension support bar is provided with Anti-slip cover.
The utility model is folded and is provided with two hollow treadles by the terraced bar top at vertical ladder, described in each, in hollow treadle, be arranged with one can be in described hollow treadle after pull-out locking laterally as the horizontal expansion support bar of described vertical ladder upper support, the terraced bar bottom X-shaped intersection of described vertical ladder is provided with two hollow reinforced pipes, described in each, in hollow reinforced pipe, be arranged with the oblique extension support bar as described vertical ladder bottom support after can be in a described hollow reinforced pipe oblique lower pull-out locking, thereby can make this ladder adaptation ground injustice or leading surface have empty place as usual to use.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the adjustable wide foot of ladder that the utility model embodiment provides
Figure 2 shows that the schematic diagram under Fig. 1 closure state.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1～2, a kind of adjustable wide foot of ladder, comprise a vertical ladder 1, the terraced bar top of described vertical ladder 1 is folded and is provided with two hollow treadles 2,3, described in each, in hollow treadle, be arranged with one can be in described hollow treadle after pull-out locking laterally as the horizontal expansion support bar 21,31 of described vertical ladder upper support, the terraced bar bottom X-shaped of described vertical ladder 1 intersects and is provided with two hollow reinforced pipes 4,5, described in each, in hollow reinforced pipe, be arranged with one can be in described hollow reinforced pipe the oblique extension support bar 41,51 as described vertical ladder bottom support after oblique lower pull-out locking.
Further, the outer end of described horizontal expansion support bar 21,31 is provided with respectively Anti-slip cover 22,32.
Further, the bottom of described oblique extension support bar 41,51 is provided with Anti-slip cover 41,52.
Further, between described hollow treadle and described horizontal expansion support bar, and be provided with locking device between described hollow reinforced pipe and described oblique extension support bar.
Described locking device can be provided in a side of the lock hole on described hollow treadle (or hollow reinforced pipe) and be located at securing rod (pin) or the columnar projections of the described lock hole of correspondence on described horizontal expansion support bar (or oblique extension support bar), described securing rod (pin) or columnar projections are under external force, can be pressed in described horizontal expansion support bar (or oblique extension support bar), during without External Force Acting, can in horizontal expansion support bar (or oblique extension support bar), outwards eject.
When the utility model need to be adjusted leading surface cavity width, by the horizontal expansion support bar pull-out of upper end, in case of there is the extension support bar below step or sloping floor pull-out on ground, adjust length, and locking, after ascending a height, regain, can do common vertical ladder and use.In addition, in storage, when carrying is convenient, volume is little, and lightweight.
The utility model is folded and is provided with two hollow treadles by the terraced bar top at vertical ladder, described in each, in hollow treadle, be arranged with one can be in described hollow treadle after pull-out locking laterally as the horizontal expansion support bar of described vertical ladder upper support, the terraced bar bottom X-shaped intersection of described vertical ladder is provided with two hollow reinforced pipes, described in each, in hollow reinforced pipe, be arranged with the oblique extension support bar as described vertical ladder bottom support after can be in a described hollow reinforced pipe oblique lower pull-out locking, thereby can make this ladder adaptation ground injustice or leading surface have empty place as usual to use.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
