Technical problem to be solved in the utility model is to provide the climbing ladder cart of a kind of reasonable in design, adjustable-angle easy to use.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of climbing ladder cart of adjustable-angle, comprise the underframe depositing goods, described underframe rear side end is hinged with the armrest frame in order to push-and-pull underframe, described armrest frame be also provided with the slider-rocker mechanism regulating the relative underframe angle of armrest frame between underframe, the both sides of described underframe are provided with three castors in order to speeling stairway.
Further, described slider-rocker mechanism comprises slide block, head and the collar bearing fit be fixed in the middle part of described armrest frame of described slide block, the bottom of described slide block is hinged with two connecting rods simultaneously, described connecting rod is all hinged through rocking bar and armrest frame, described rocking bar is all hinged with L shape latch, the bilateral symmetry of described underframe is intervally distributed with some through holes in order to match with L shape latch.
Further, the head end of described connecting rod and the bottom of slide block are hinged, and the tail end of connecting rod and the head end of rocking bar are hinged, and tail end and the armrest frame of described rocking bar are hinged.
Further, front end, described underframe downside is provided with the universal caster wheel regulating direction.
Further, described slide block is provided with draw ring.
Compared with prior art, the utility model has following beneficial effect: the utility model structure design is simple, convenient to use, according to actual needs, change the relative angle between underframe and armrest frame by adjustment slider-rocker mechanism, even underframe and armrest frame can be piled up completely, greatly reduce floor area, all right speeling stairway of the utility model, multiple functional, have great practical value, be easy to promote.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-underframe, 2-armrest frame, 3-slider-rocker mechanism, 31-slide block, 32-connecting rod, 33-rocking bar, 34-L shape latch, 4-tri-castor, the 5-collar, 6-through hole, 7-universal caster wheel, 8-draw ring.
Detailed description of the invention
As shown in Figure 1, a kind of climbing ladder cart of adjustable-angle, comprise the underframe 1 depositing goods, described underframe 1 rear side end is hinged with the armrest frame 2 in order to push-and-pull underframe 1, described armrest frame 2 be also provided with between underframe 1 in order to regulate and the slider-rocker mechanism 3 of fixing armrest frame 2 relative underframe 1 angle, the both sides of described underframe 1 are provided with three castors 4 in order to speeling stairway.
In the present embodiment, described slider-rocker mechanism 3 comprises slide block 31, head and the collar 5 bearing fit be fixed in the middle part of described armrest frame 2 of described slide block 31, the bottom of described slide block 31 is hinged with two connecting rods 32 simultaneously, described connecting rod 32 is all hinged through rocking bar 33 and armrest frame 2, described rocking bar 33 is all hinged with L shape latch 34, the bilateral symmetry of described underframe 1 is intervally distributed with some through holes 6 in order to match with L shape latch 34, when the angle changed between underframe 1 and armrest frame 2 but when underframe 1 and armrest frame 2 not being folded, be pulled upwardly slide block 31, the relative motion of two connecting rods 32 is until two connecting rods 32 close, in the process that two connecting rods 32 are closed, two rocking bars 33 all rotate around the hinge-point of rocking bar 33 with armrest frame 2, in the process that two rocking bars 33 rotate, drive L shape latch 34 to extract from corresponding through hole 6, regulate the angle of underframe 1 and armrest frame 2 to needs angle, downward release slide block 31, two connecting rods 32 separately, two rocking bars 33, L shape latch 34 all rotates, two L shape latches 34 are caused to insert in required through hole 6, when underframe 1 folds with armrest frame 2 by needs, be pulled upwardly slide block 31, the relative motion of two connecting rods 32 is until two connecting rods 32 close, in the process that two connecting rods 32 are closed, two rocking bars 33 all rotate around the hinge-point of rocking bar 33 with armrest frame 2, in the process that two rocking bars 33 rotate, drive L shape latch 34 to extract from corresponding through hole 6, regulate underframe 1 to fold to underframe 1 and armrest frame 2 with the angle of armrest frame 2.
In the present embodiment, the head end of described connecting rod 32 and the bottom of slide block 31 are hinged, and the tail end of connecting rod 32 and the head end of rocking bar 33 are hinged, and tail end and the armrest frame 2 of described rocking bar 33 are hinged.
In the present embodiment, front end, described underframe 1 downside is provided with the universal caster wheel 7 regulating direction.
In the present embodiment, described slide block 31 is provided with draw ring 8.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
