The utility model content
At above problem, the purpose of this utility model provides a kind of ladder of can doing and uses and can make scaffold again and use, and moves, carrying, preservation ladder very easily, and is particularly a kind of by the molecular scaffold of folding ladder.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of by the molecular scaffold of folding ladder, comprise vertical rod group, horizon bar group, support, bridging, described vertical rod group can be that several ladders unit is joined together to form an integral body by the hinges structure; Described horizon bar group also can be that several ladders unit is joined together to form an integral body by the hinges structure; Link together by the hinges structure between described vertical rod group and the horizon bar group.
Described hinges structure comprises short metal tube, metal sheet, junction plate, axis, splicing sleeve, connecting hole and pin, weld together side by side by a metal sheet between the identical short metal tube of two specifications, be inserted in an axis respectively in two short metal tubes, this axis one end is provided with pin-and-hole and pin, and the other end is provided with the retaining sheet that prevents that axis from skidding off from metal tube; The axis of two short metal tubes is put into the connecting hole that end, ladder unit is reserved respectively, and is free to rotate; Outside symmetry at this hinges structure junction plate is on one side fixed two splicing sleeves, the cross sectional shape of this splicing sleeve is being a square tube shape near the junction plate place, be right-angled triangle away from the junction plate place, this splicing sleeve has a screw on top, right-angled triangle place.
When two joint ladder unit link together with the hinges structure, the second joint ladder unit side frame lower bottom part, in the corresponding place of splicing sleeve right-angled triangle place top screw therewith one bolt is set, this bolt splicing sleeve right-angled triangle place top screw therewith is complementary, this bolt lower end has the turn handwheel, and the bolt upper end has the retaining screw plug.
Described support, bridging all are connected with the ladder unit with movable pin.
Splicing sleeve in the described hinges structure can be fixedlyed connected with the ladder unit, also can flexibly connect by bolt with the ladder unit.
This by the molecular scaffold of folding ladder, its horizon bar group can be made up of than the ladder unit of comparatively dense cross bar, is convenient to the scaffold pedal that personnel operate in the above so that form.
The utility model is connected together the ladder unit in twos by hinge arrangement, form an integral body, both can make the horizon bar group of scaffold, also can make the vertical rod group of scaffold, link together by the hinges structure between described vertical rod group and the horizon bar group, add and support and bridging, so just formed a scaffold; In addition, form an integral body, just form long ladder when a plurality of ladders unit is connected together in twos; Such combination is not only moved, carrying, preservation are very convenient, and one-object-many-purposes, has increased function of use, both can make scaffold and use, and can make ladder again and use.
The specific embodiment
Fig. 1 is the structural representation of the utility model scaffold, comprises vertical rod group 1, horizon bar group 6, support 3, bridging 7, and described vertical rod group 1 can be that several ladders unit 4 is joined together to form an integral body by hinges structure 5; Described horizon bar group 6 also can be that several ladders unit is joined together to form an integral body by hinges structure 5; Also link together between described vertical rod group 1 and the horizon bar group 6 by hinges structure 5.
From Fig. 2, Fig. 3 as can be seen: described hinges structure 5 comprises short metal tube 13, metal sheet 14, connector 15, axis 10, splicing sleeve 12, screw 16 and pin 9, two identical short metal tubes 13 of specification are welded on the junction plate 14 side by side, be inserted in an axis 10 respectively in two short metal tubes 13, this axis one end is provided with pin-and-hole and pin 11, and the other end is made retaining sheet 17; The axis of two short metal tubes is put into the connecting hole that 4 ends, ladder unit are reserved respectively, and is free to rotate; Outside symmetry at this hinges structure 5 connector 15 is on one side fixed two splicing sleeves 12, the cross sectional shape of this splicing sleeve 12 is being a triangle away from connector 15 places, be square tube shape near connector 15 places, this splicing sleeve 12 has a screw 16 on top, right-angled triangle place; When two joint ladder unit link together with hinges structure 5, another joint ladder side frame lower bottom part of no splicing sleeve, in splicing sleeve 12 right-angled triangle place top screws 16 corresponding places therewith one bolt that is complementary 9 is set, these bolt 9 lower ends have turn handwheel 18, and the upper end has retaining screw plug 8.
Support among Fig. 12,3 and bridging 7,11 all be connected with the ladder unit activity with pin.
Splicing sleeve 12 in the described hinges structure 5 can be fixedlyed connected with the ladder unit, also can flexibly connect by bolt with the ladder unit.
The described scaffold of being made up of the ladder unit, its horizon bar group 6 can be made up of than the ladder unit of comparatively dense cross bar 19, is convenient to the scaffold pedal that personnel operate in the above so that form.
