Abstract
The utility model relates to the technical field of the climbing tool. The utility model discloses a folding type multi-functional ladder. The utility model comprises a plurality of ladder frames; the adjacent ladder frames are connected by a hinge device; wherein, the hinge device consists of a main hinge piece and a subsidiary hinge piece which can rotate relatively; a limit mechanism is mounted between the main hinge piece and the subsidiary hinge piece. Each adjacent ladder frame of the utility model can rotate relatively and the ladder presents in various types; the limit mechanism which is mounted between the main hinge piece and the subsidiary hinge piece can fasten the type of the ladder. Not only the operation and the application are very convenient, but also the firmness of the ladder is increased which avoids the shaking phenomenon of the ladder.
Description
Technical field:
The utility model relates to the climbing technical field of tools, especially relates to a kind of folding ladder.
Background technology:
Ladder is one of people's instrument commonly used in daily life, and its pattern is varied, and a kind of folding ladder that is is wherein arranged, and it can be opened in use, can draw in after finishing using to reduce shared space.Folding ladder is made of a plurality of ladders, links to each other so that ladder can relatively rotate by hinge means between each two adjacent ladder.But the shortcoming that existing folding ladder all exists complicated operation, poor, the easy integral body of sound construction to rock is necessary to be improved.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of new collapsible multipurpose ladder is provided that it has characteristics firm, easy for operation simple in structure.
For achieving the above object, the utility model comprises a plurality of ladders, links to each other by hinge means between two adjacent ladders, wherein, described hinge means is made of relatively turnable main hinge sheet and secondary hinge plate, is provided with position-limit mechanism between main hinge sheet and the secondary hinge plate.
Described main hinge sheet and secondary hinge plate constitute by the rotation section of circle and the connecting portion of strip, the rotation section of main hinge sheet and secondary hinge plate is superimposed together, connecting portion then links to each other with ladder, wherein, offer chute on the rotation section of main hinge sheet, the elasticity fixture block is installed in the chute, offers a plurality of locating slots that cooperate with fixture block on the excircle of secondary hinge plate rotation section.
The flexible catch of hinged inside of secondary hinge plate rotation section, elastic block piece has the blocking arm identical with locating slot quantity.
Outermost two ladder lower ends are provided with support foot.
The beneficial effects of the utility model are: can relatively rotate between its each adjacent ladder, make ladder present various kenel, and be arranged at the main hinge sheet of hinge means and the kenel that the position-limit mechanism between the secondary hinge plate can be fixed ladder, not only operation and very easy to use, and increased the fastness of ladder, make it the phenomenon that integral body is rocked can not occur.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a user mode schematic diagram of the present utility model;
Accompanying drawing 2 is the combination schematic diagram (from the front) of hinge means;
Accompanying drawing 3 is the decomposing schematic representation of hinge means (from the back side);
Accompanying drawing 4 is the combination schematic diagram (from the back side) of hinge means.
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See that accompanying drawing 1 is to shown in the accompanying drawing 4: (in fact the utility model comprises four ladders 10,20,30,40, the quantity of ladder is not limited to four, it also can be even numbers such as six, eight), link to each other by hinge means between adjacent two ladders 10 and 20,20 and 30 and 30 and 40.See shown in accompanying drawing 2 and the accompanying drawing 3: hinge means is made of relatively turnable main hinge sheet 50 and secondary hinge plate 60, and main hinge sheet 50 and secondary hinge plate 60 constitute by the rotation section 51,61 of circle and the connecting portion 52,62 of strip; The rotation section 51,61 of main hinge sheet 50 and secondary hinge plate 60 is superimposed together, 52,62 of connecting portions link to each other with ladder, offer chute 511 on the rotation section 51 of main hinge sheet 50, elasticity fixture block 512 is installed in the chute 511, offer a plurality of locating slots 611 that cooperate with fixture block 512 on the excircle of the rotation section 61 of secondary hinge plate 60, elasticity fixture block 512 and locating slot 611 constitute position-limit mechanism.After main hinge sheet 50 and secondary hinge plate 60 relatively rotated certain angle, elasticity fixture block 512 snapped in the locating slot 611 under the elastic force effect, thereby fixes the kenel of ladder; And will change the ladder kenel time, then elasticity fixture block 512 can be pulled back along chute 511, itself and locating slot 611 are broken away from, like this, two adjacent ladders then can be rotated further, make ladder present different moulding, such as herringbone, bench type, yi word pattern etc., or gathering folds fully.
In addition, the flexible catch 612 of the hinged inside of the rotation section 61 of secondary hinge plate 60, elastic block piece 612 have and the identical blocking arm of locating slot 611 quantity, can prevent that like this slip phenomenon from appearring in elasticity fixture block 512 when not snapping in the locating slot 611 fully.
In addition, outermost two ladders of ladder 10,40 lower ends are provided with support foot 70, and support foot 70 bottoms form anti-slop serrations, to increase the frictional force on ladder and ground, make it be not easy to slide.
Claims (4)
1. collapsible multipurpose ladder, it comprises a plurality of ladders, link to each other by hinge means between two adjacent ladders, it is characterized in that: described hinge means is made of relatively turnable main hinge sheet and secondary hinge plate, is provided with position-limit mechanism between main hinge sheet and the secondary hinge plate.
2. collapsible multipurpose ladder according to claim 1, it is characterized in that: described main hinge sheet and secondary hinge plate constitute by the rotation section of circle and the connecting portion of strip, the rotation section of main hinge sheet and secondary hinge plate is superimposed together, connecting portion then links to each other with ladder, wherein, offer chute on the rotation section of main hinge sheet, the elasticity fixture block is installed in the chute, offer a plurality of locating slots that cooperate with fixture block on the excircle of secondary hinge plate rotation section.
3. collapsible multipurpose ladder according to claim 2 is characterized in that: the flexible catch of hinged inside of secondary hinge plate rotation section, elastic block piece has the blocking arm identical with locating slot quantity.
