First region of described main ladder support and the corresponding side of described bottom ladder, is evenly provided with the affixed assemblies of many groups;
The top of support frame as described above is provided with affixed deflation mechanism;
The described affixed mechanism of tightening can organize any one group of suitable connection the in affixed assembly with described more, and support frame as described above is supported described main ladder support;
Described bottom ladder, main ladder support and bracing frame surround triangle space.
Above-mentioned combination ladder, preferred, described affixed assembly comprises two affixed projections;
On the corresponding support arm that is separately positioned on described main ladder support of described two affixed projections.
Above-mentioned combination ladder, preferred, the bottom of described bottom ladder is provided with removable pulley.
From technique scheme, can find out, in the combination ladder that the utility model provides, bottom ladder, main ladder support and supporting frame group are synthesized a triangular framing; The two ends of bottom ladder are connected with bracing frame with main ladder support by wheel shaft respectively, and making described main ladder support and support frame as described above can wheel shaft be that the strong point planar rotates; Regulate the fitting relation between affixed deflation mechanism and the affixed assembly of many groups simultaneously, play in the horizontal direction and object that vertical direction regulates combination ladder, make more firmly safety of work high above the ground.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of a kind of combination ladder that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.
With reference to figure 1, show the structural representation of a kind of combination ladder that the utility model provides, comprising:
Bottom ladder 102, main ladder support 103 and bracing frame 104;
Wherein:
One end of described bottom ladder 102 is connected with the bottom of described main ladder support 103 by the first wheel shaft 101, and the other end of described bottom ladder 102 is connected with the bottom of support frame as described above 104 by the second wheel shaft 107;
First region of described main ladder support 103 and described bottom ladder 102 corresponding sides, is evenly provided with the affixed assemblies 106 of many groups;
The top of support frame as described above 104 is provided with affixed deflation mechanism 105;
The described affixed mechanism of tightening can organize any one group of suitable connection the in affixed assembly with described more, and 104 pairs of described main ladder supports 103 of support frame as described above are supported;
Described bottom ladder 102, main ladder support 103 and bracing frame 104 surround triangle space.
In the combination ladder that the utility model provides, described affixed assembly 106 comprises two affixed projections;
On the corresponding support arm that is separately positioned on described main ladder support 103 of described two affixed projections.
In the combination ladder that the utility model provides, on two support arms of main ladder support 103, be disposed with respectively the affixed assembly 106 of many groups, on each support arm, be disposed with a plurality of projections, two projections corresponding on two support arms form an affixed assembly.
Affixed deflation mechanism 105 comprises a crossbeam, described crossbeam is fixed on the top of support frame as described above 104, the two ends of described crossbeam are respectively arranged with two draw-in grooves, described two draw-in grooves respectively with described main ladder support on one group of affixed assembly in two protruding phase clampings, 104 pairs of main ladder supports 103 of bracing frame are played a supporting role.
Affixed contracted structure and different affixed assembly phase clamping, be all moved the main ladder support in described combination ladder in the horizontal direction with vertical direction.
In the combination ladder that the utility model provides, affixed assembly is arranged on the upper area of described main ladder support, when guaranteeing affixed assembly with affixed contracted structure phase clamping, the angle forming between main ladder support and bottom ladder within the specific limits, and do not make main ladder support too skew in the vertical direction, fall.
The combination ladder that the utility model provides in use, is determined according to the far and near height of working space situation and actual needs, as long as the connecting portion of the upper end of main ladder support and bracing frame and bottom ladder is fixed and can be climbed or Job Operations.Operating personnel can be on main ladder support, also can be on the ladder of bottom.Compared with prior art, this combination ladder not only can change horizontal and vertical distance, uses flexibly, and makes operating personnel's scope of activities large and steady, therefore safe and reliable.In addition, not the used time, as long as open the retaining mechanism of bracing frame and bottom ladder, collapsible merging reduced volume, therefore easy to carry and transport.
The bottom of described bottom ladder is provided with removable pulley, thereby it is more efficient and convenient that described combination ladder is moved.
