Abstract
The utility model discloses a reversible step ladder which is characterized by comprising a working platform and an up-and-down platform step ladder, wherein the front side of the working platform is provided with an entrance/exit through which the personnel go in and out; the up-and-down platform step ladder is rotationally arranged on the bottom side of the front side of the working platform through a step ladder turning shaft; a first machine leg for supporting in the process of folding the up-and-down platform step ladder is fixed on the top of the entrance/exit; and a second machine leg for supporting in the process of unfolding the up-and-down platform step ladder is fixed below the working platform. Compared with the prior art, the reversible step ladder has the advantages and effects that the step ladder is simple and reasonable in structure, low in manufacturing cost, small in occupied space, time-saving and labor-saving, can be turned and folded and provides convenience for the staff to go up and down the working platform.
Description
Technical field
The utility model relates to a kind of turning step.
Background technology
At present the work high above the ground personnel working platform is basic up and down walks platen from ground by fixing step to secondary crossbeam earlier, then by working platform about other steps, perhaps walk platen working platform up and down through secondary crossbeam, very inconvenient as this action, particularly go down working platform arrival ground spended time and grow, consume one's energy many.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, good reliability, easy to use, make turning step simple, that the cooperating platform uses.
The technical scheme in the invention for solving the above technical problem is: this turning step, it is characterized in that: comprise working platform, last lower platform step, the front of described working platform offers the access of coming in and going out for personnel, last lower platform step is rotatably installed in by the step trip shaft on the base in front of working platform, first under-chassis that supports usefulness when keeping supplying the lower platform step and packing up is fixedly arranged at the top of access, fixedly have below the working platform and keep supplying second under-chassis that supports usefulness when the lower platform step launches, the corresponding dual-side fixed-site that goes up the lower platform step has pair of brackets on the below of working platform, night bolt is installed on the support, night bolt fixedly has the latch handle, offers the jack that matches with night bolt on the last lower platform step; Also slide on the dual-side of access and be provided with when packing up for last lower platform step fixedly the first locking latch and second of usefulness and lock latch, offer the jack that matches with the first locking latch and the second locking latch on the last lower platform step, the first locking latch and the second locking latch are furnished with wing nut.
The handrail that uses when last lower platform is fixedly arranged on the dual-side of access described in the utility model.
The material of going up the lower platform step described in the utility model adopts aluminum alloy material.
The utility model compared with prior art has the following advantages and effect: simple and reasonable, low cost of manufacture, turning pack up, take up room little, for the staff up and down working platform convenience is provided, has saved time and laborsaving.
Description of drawings
Fig. 1 is the last lower platform step of the utility model embodiment structural representation when launching.
Fig. 2 is the last lower platform step of the utility model embodiment structural representation when packing up.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1-Fig. 2, the turning step of present embodiment, comprise working platform 10, last lower platform step 1, the front of working platform 10 offers the access of coming in and going out for personnel, last lower platform step 1 is rotatably installed in by step trip shaft 3 on the base in front of working platform 10, first under-chassis 6 that supports usefulness when keeping supplying lower platform step 1 and packing up is fixedly arranged at the top of access, fixedly have below the working platform 10 and keep supplying second under-chassis 8 that supports usefulness when lower platform step 1 launches, the corresponding dual-side fixed-site that goes up lower platform step 1 has pair of brackets on the below of working platform 10, night bolt 2 is installed on the support, night bolt 2 fixedly has latch handle 9, offers the jack that matches with night bolt 2 on the last lower platform step 1; Also slide on the dual-side of access and be provided with when packing up for last lower platform step 1 fixedly the first locking latch 4 and second of usefulness and lock latch 7, offer the jack that matches with the first locking latch 4 and the second locking latch 7 on the last lower platform step 1, the first locking latch 4 and the second locking latch 7 are furnished with wing nut.Last lower platform handrail 5 is fixedly arranged on the dual-side of access.The material of last lower platform step 1 adopts aluminum alloy material.
The operating principle of the turning step of present embodiment: the wing nut on the first locking latch 4 and the second locking latch 7 is unclamped, the first locking latch 4 and the second locking latch 7 are extracted, just can turn down around rotating shaft 3 going up lower platform step 1, use latch handle 9 rotation spring latches 2 then, the elastic force effect of night bolt 2 compressed springs, be inserted into the jack of lower platform step 1, last lower platform step 1 is locked by night bolt 2, and the staff can use lower platform step working platform 10 about in the of 1.If last lower platform step 1 is regained, then at first extract night bolt 2 with latch handle 9, rotation spring latch 2 lockings then (rotation direction is opposite when locking steps with use latch 2) prevent from ejecting, then will go up lower platform step 1 up overturns, when two jacks on the last lower platform step 1 align with the first locking latch 4 and the second locking latch 7, the first locking latch 4 and the second locking latch 7 are inserted in the jack of step 1, use the wing nut locking first locking latch 4 and the second locking latch 7, note during locking can not first under-chassis 6 press tension.
The turning step of present embodiment not only for the staff up and down working platform convenience is provided, and take up room and be particularly suitable for for a short time being applied on the working platform with folder function.
Above content described in this manual only is to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of the utility model manual or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
