The folding ladder has the advantages that the folding ladder is portable and can be used as step ladder, vertical ladder and bracket.

Description

A kind of folding ladder that makes things convenient for

The utility model relates to a kind of ladder, especially a kind of folding ladder that makes things convenient for.

At present double ladder and the vertical ladder that uses can not fold, carry very inconvenient, and, can not change between double ladder and the vertical ladder, bring inconvenience to use.

It is folding that the purpose of this utility model provides a kind of convenience, easy to carry, can make the folding ladder that makes things convenient for of double ladder, vertical ladder or support use.

For achieving the above object, the utility model is a kind of to be made things convenient on the revolving part of connection positioner of folding ladder rotating hole, around rotating hole, be evenly distributed with 3-8 tip hole, connection handle is arranged on the revolving part, the axis of rotation that is fixed on the keeper is corresponding with the rotating hole on the revolving part, one end of axis of rotation has inner bolt hole, 3-8 the pin that is fixed on the keeper is corresponding with 3-8 tip hole on the revolving part, axis of rotation on the keeper passes two rotating holes on the revolving part, pass spring again, the hole that screw passes on the packing ring is connected with inner bolt hole on the axis of rotation, 3-8 on a keeper pin correspondingly is inserted in two 3-8 on revolving part tip hole, a hole is arranged on the fixed leg on the keeper, the hole that bolt passes on the fixed leg on hole and the keeper on the projection of handgrip one end is connected with nut, the corresponding opening that is inserted on the keeper of the projection of handgrip one end, the connection handle on the revolving part of connection positioner is fixedlyed connected with horizontal terraced bar.

After adopting such structure, stir the handgrip that connects in the positioner, then, make two revolving parts rotations, after the pin on the keeper correspondingly is inserted in two tip holes on the revolving part, make to make things convenient for folding ladder to become double ladder, vertical ladder, support or be folded state.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a kind of connection positioning device structure schematic diagram that makes things convenient for folding ladder of the utility model.

Fig. 2 is a kind of structural representation that makes things convenient for folding ladder of the utility model.

Fig. 3, Fig. 4, Fig. 5, Fig. 6 are a kind of user mode figure that makes things convenient for folding ladder of the utility model.

As Fig. 1, on the revolving part 11 of a kind of connection positioner 19 that makes things convenient for folding ladder shown in Figure 2 rotating hole 12 is arranged, around rotating hole 12, be evenly distributed with 3-8 tip hole 13, connection handle 14 is arranged on the revolving part 11, the axis of rotation 9 that is fixed on the keeper 5 is corresponding with the rotating hole 12 on the revolving part 11, one end of axis of rotation 9 has inner bolt hole, 3-8 the pin 10 that is fixed on the keeper 5 is corresponding with 3-8 tip hole 13 on the revolving part 11, axis of rotation 9 on the keeper 5 passes two rotating holes 12 on the revolving part 11, pass spring 15 again, the hole 17 that screw 18 passes on the packing ring 16 is connected with inner bolt hole on the axis of rotation 9,3-8 on the keeper 5 pin 10 correspondingly is inserted in two 3-8 on the revolving part 11 tip hole 13, a hole 8 is arranged on the fixed leg 6 on the keeper 5, the hole 8 that bolt 4 passes on the fixed leg 6 on hole 3 and the keeper 5 on the projection of handgrip 1 one ends is connected with nut 2, the corresponding opening 7 that is inserted on the keeper 5 of the projection of handgrip 1 one ends, the connection handle 14 on the revolving part 11 of connection positioner 19 is fixedlyed connected with horizontal terraced bar 20.

During use, making vertical ladder, double ladder or support as need uses, stir the handgrip 1 that connects in the positioner 19, then, make 11 rotations of two revolving parts, after pin 10 on the keeper 5 correspondingly is inserted in two tip holes 13 on the revolving part 11, make to make things convenient for folding ladder to become vertical ladder as shown in Figure 3, become double ladder as shown in Figure 4, become support as shown in Figure 5, when carrying, make to make things convenient for folding ladder to become folded state as shown in Figure 6.
