Abstract
The utility model relates to a kind of Collapsible ladder, comprise main ladder and bracing frame, described main ladder is made up of two risers, the upper end of two risers is connected by secondary ladder, the centre position of two riser formations is connected with one group of main pedal, the side of each main pedal is hingedly connected together by foot pedal support frame, and two ends and two risers of the opposite side of each main pedal lower position are coupling, and making winner's pedal fold rear is same plane with two montants.The effect that the utility model is useful is: due to have employed T-shaped crank arm A with crank arm B and being connected by joint of cranking arm, considerably increase the stability of the open mode of ladder; The side of each main pedal is hingedly connected together by foot pedal support frame, and two ends of opposite side and two risers are coupling, instead of the mode that common side is hinged, after making to open, and main pedal stability and safety more.
Description
Technical field
The utility model relates to ladder field, especially a kind of Collapsible ladder.
Background technology
Existing ladder is folding mostly folding inconvenient, and when opening and using, stability and intensity poor, people stands in above ladder and rolls, and safety is poor.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of Collapsible ladder.
The utility model solves the technical scheme that its technical problem adopts: this Collapsible ladder, comprise main ladder and bracing frame, described main ladder is made up of two risers, the upper end of two risers is connected by secondary ladder, the centre position of two riser formations is connected with one group of main pedal, the side of each main pedal is hingedly connected together by foot pedal support frame, two ends and two risers of the opposite side of each main pedal lower position are coupling, making winner's pedal fold rear is same plane with two montants, the upper position of described main ladder is socketed with the sliding sleeve that can slide on main ladder, sliding sleeve is hinged by one end of runner and bracing frame, the lower position of main ladder is provided with connecting rod, two ends of connecting rod are connected with the chute in roller through riser, a position of chute makes roller raise, another position of chute makes roller reduce, the rotational angle of connecting rod is corresponding with the position of chute, the A that cranks arm is T-shaped, and its one end is connected with the riser of the lower position of main ladder, the B that cranks arm is T-shaped, and its one end is connected with bracing frame, the other end of A of cranking arm is connected with the other end of the B that cranks arm by joint of cranking arm.
The centre position of described connecting rod is provided with roller pedal.
The effect that the utility model is useful is: due to have employed T-shaped crank arm A with crank arm B and being connected by joint of cranking arm, considerably increase the stability of the open mode of ladder; The side of each main pedal is hingedly connected together by foot pedal support frame, and two ends of opposite side and two risers are coupling, instead of the mode that common side is hinged, after making to open, and main pedal stability and safety more; Connecting rod controls the lifting of roller, when making mobile and use, convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this Collapsible ladder, comprise main terraced 3 and bracing frame 8, it is characterized in that: described main terraced 3 are made up of two risers, the upper end of two risers is connected by secondary ladder 1, the centre position of two riser formations is connected with one group of main pedal 12, the side of each main pedal 12 is hingedly connected together by foot pedal support frame 9, two ends and two risers of the opposite side of each main pedal 12 lower position are coupling, making winner's pedal 12 fold rear is same plane with two montants, the described main upper position of terraced 3 is socketed with the sliding sleeve 2 that can slide on main terraced 3, sliding sleeve 2 is hinged by runner 4 one end with bracing frame 8, the main lower position of terraced 3 is provided with connecting rod 13, two ends of connecting rod 13 are connected with the chute 14 in roller 11 through riser, a position of chute 14 makes roller 11 raise, another position of chute 14 makes roller 11 reduce, the rotational angle of connecting rod 13 is corresponding with the position of chute 14, namely rotation angle of connecting rod can control the lifting of roller 11, the centre position of described connecting rod 13 is provided with roller pedal 10.The A5 that cranks arm is T-shaped, and its one end is connected with the riser of the main lower position of terraced 3; The B6 that cranks arm is T-shaped, and its one end is connected with bracing frame 8; The other end of A5 of cranking arm is connected with the other end of the B6 that cranks arm by joint 7 of cranking arm.
When packing up, as shown in Figure 1-2, the A5 and the B6 that cranks arm that cranks arm folds, and main pedal 12 folds, and now controls 10 roller pedals and puts down 11 rollers, can carry out by hand steered secondary ladder 1 pair of ladder, convenient mobile.
When opening, as shown in Figure 3 and Figure 4, pull open bracing frame 8, the A5 and the B6 that cranks arm that cranks arm stretches thereupon, and main pedal 12 is set level thereupon, reaches duty.Duty only needs control pedal roller 10, connecting rod that roller 11 is put down as needed mobile ladder.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
