Description
Technical field
The utility model relates to folding ladder, particularly a kind of folding ladder with locking function.
Background technology
Ladder is a kind of instrument be in daily use in people's daily life, and traditional ladder has single rack ladder and folding ladder, and single ladder bed structure is simple, use flexibly, but stable not, and height cannot be regulated, folding ladder improves stability for single ladder, but still cannot overcome the defect of height.Therefore, have the corrective measure of ladder always.
Application number is that the patent " folding ladder " of " 201210403062.8 " passes through anker supporting leg on the hinge hinge of common folding ladder, can improve the stability of folding ladder, but it does not solve the problem how improving stability and regulate height simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of folding ladder with locking function, can lock when gathering, opens Shi Jike and does folding ladder use, can make again single rack ladder and use, flexibly and easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of folding ladder with locking function, and it comprises ladder main body one, ladder main body two, ladder main body one and ladder main body two are undertaken hinged by hinge, and junction plate is fixedly connected with ladder main body two; The vertical bar in ladder main body one left and right sides first, the hole that the vertical bar in ladder main body two left and right sides second is identical with junction plate being drilled with multiple size; Termination, pull bar two ends bends, and pull bar one end and the first vertical bar are hinged, and the pull bar other end is for being connected with junction plate.
In double ladder state, the other end of pull bar is fixedly connected with junction plate; In vertical ladder state, junction plate is connected with the be turned into vertical state first vertical bar and the second vertical bar.
The anglec of rotation of described hinge is limited to 180 degree.
Described pull bar bending part is provided with external screw thread, is threaded with nut, and pull bar is fixed on the first vertical bar, the second vertical bar and junction plate.
Described first vertical bar is corresponding with the position in the hole on junction plate with the hole on the second vertical bar.
A kind of folding ladder with locking function that the utility model provides, by adopting above-mentioned structure, has following beneficial effect:
1, draw locking in: when folding ladder draws, the first vertical bar is passed in termination, pull bar two ends, the corresponding hole on the second vertical bar and junction plate, and fix with nut, play the object of locking.
2, two supporting leg: ladder main body one and ladder main body two are opened certain angle, by pull bar both ends horizontal through the first vertical bar, the hole of the correspondence on the second vertical bar and junction plate, and fix with nut.For common folding ladder, by locking two ladders, stability improves further.
3, single supporting leg: side ladder main body is revolved turnback, simultaneously junction plate also revolves turnback and is tightened by bolts, pull bar two ends are passed vertically through the first vertical bar, the hole of the correspondence on the second vertical bar and junction plate, and fix with nut, lock, realize two supporting leg being converted into the single supporting leg extending version, thus realize the adjustment of height.

In figure: ladder main body 1, ladder main body 22, hinge 3, junction plate 4, the vertical bar 6 of the first vertical bar 5, second, hole 7, pull bar 8, external screw thread 9, nut 10.
Detailed description of the invention
As shown in Fig. 1 ~ 4, a kind of folding ladder with locking function, it comprises ladder main body 1, ladder main body 22, and ladder main body 1 and ladder main body 22 are undertaken hinged by hinge 3, and junction plate 4 is fixedly connected with ladder main body 22; The vertical bar 5 in ladder main body 1 left and right sides first, the vertical bar 6 in ladder main body 22 left and right sides second with junction plate 4 is drilled with the identical hole of multiple size 7; Termination, pull bar 8 two ends bends, and pull bar 8 one end and the first vertical bar 5 are hinged, and pull bar 8 other end is for being connected with junction plate 4.
In double ladder state, the other end of pull bar 8 is fixedly connected with junction plate 4; In vertical ladder state, junction plate 4 is connected with the be turned into vertical state first vertical bar 5 and the second vertical bar 6.
The anglec of rotation of described hinge 3 is limited to 180 degree.
Described pull bar 8 bending part is provided with external screw thread 9, is threaded with nut 10, and pull bar 8 is fixed on the first vertical bar 6 of vertical bar 5, second and junction plate 4.
Described first vertical bar 5 is corresponding with the position in the hole 7 on junction plate 4 with the hole on the second vertical bar 6.
1, in time not needing to use, draw the first vertical bar 5 of ladder main body 1 and the second vertical bar 6 of ladder main body 22 in, pull bar 8 two ends are each passed through the suitable hole 7 on the first vertical bar 5 of ladder main body 1, the second vertical bar 6 of ladder main body 22 and junction plate 4, and fix with nut 10, play the object of locking.
2, when using as folding ladder: ladder main body 1 and ladder main body 22 are opened certain angle, by the hole 7 of pull bar 8 both ends horizontal through the correspondence on the first vertical bar 5 of ladder main body 1, the second vertical bar 6 of ladder main body 22 and junction plate 4, and fix with nut 10.For common folding ladder, by locking two ladder main bodys, stability improves further.
3, when using as single rack ladder: side ladder main body 1 or ladder main body 22 are revolved turnback, junction plate 4 also revolves turnback simultaneously, and fix with bolt, pull bar 8 two ends are passed vertically through the hole 7 of the correspondence on the first vertical bar 5 of ladder main body 1, the second vertical bar 6 of ladder main body 22 and junction plate 4, and fix with nut 10, lock, two supporting leg is converted into the single supporting leg extending version, thus realize the adjustment of height.
The above embodiments are only optimal technical scheme of the present utility model; and should not be considered as restriction of the present utility model; the technical scheme that protection domain of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
