Abstract

The utility model discloses a folding type triangular ladder, comprising a first supporting rod, a second supporting rod, a third supporting rod and a fixed mounting frame, wherein the top ends of the first supporting rod, the second supporting rod and the third supporting rod are respectively hinged with the fixed mounting frame; at least one layer of foldable transverse pedal is arranged between the first supporting rod and the second supporting rod; and a limiting piece is arranged between the first supporting rod and the third supporting rod, and a limiting piece is arranged between the second supporting rod and the third supporting rod. With the adoption of the technical scheme, the first supporting rod, the second supporting rod and the third supporting rod are unfolded by means of erecting with three feet and supporting with one another when the folding type triangular ladder is used. The utility model has the very strong stability through the interactive effect of the transverse pedal and a pull rope. When not being used, the folding type triangular ladder is folded and tied so as to be convenient to carry and save storage space. As the three supporting rods can be made of a steel tube, the utility model is light in weight.

Description

Collapsible triangle ladder

Technical field

The utility model relates to a kind of ladder, is specifically related to a kind of collapsible triangle ladder.

Background technology

Existing ladder, a kind of is single ladder, must have fixtures such as wall or column to support dependence in use, the scope of therefore using is less; Another kind is two ladders, the Eight characters ladder that two ladders are made up of two single ladders, and two single ladders can support each other in use, between two single ladders, connect with stay cord, with enhanced stability.It is big that above-mentioned two kinds of ladders all exist volume, and weight is big, carries inconvenient defective.

The utility model content

The utility model provides a kind of volume little, in light weight, portable triangle folding ladder in order to solve weak point of the prior art.

For solving the problems of the technologies described above; The utility model adopts following technical scheme: collapsible triangle ladder; Comprise first pole, second pole, the 3rd pole and fixing and mounting bracket; The top of first pole, second pole, the 3rd pole is hinged with fixing and mounting bracket respectively, is provided with the folding horizontal pedal of one deck between first pole and second pole at least, and first pole and second pole are respectively and be provided with a locating part between the 3rd pole.

Said fixing and mounting bracket is provided with column, is hinged with vertical rod on the column, also pegs graft through horizontal latch between column and the vertical rod, laterally is equipped with the vertical latch that prevents that horizontal latch is out of stock on the latch, and vertically latch is connected on the fixing and mounting bracket through cotton rope.

Said horizontal pedal is provided with five layers, on second pole, is provided with support hook, and every layer horizontal pedal one end and first pole are hinged, and the other end bottom of every layer horizontal pedal offers with support hook and articulates the draw-in groove that cooperates.

Said first pole, second pole and the 3rd pole lower end are respectively equipped with a backing plate.

Said vertical rod sidepiece is provided with hook.

Said locating part is a stay cord.

Said first pole and second pole upward with on the 3rd pole are respectively equipped with a joint push rod, are respectively equipped with the square pedal that a tile height equates on every joint push rod, and square pedal is positioned at the lower edge of the horizontal pedal of the superiors.

Adopt technique scheme, the utility model can strut first pole, second pole, the 3rd pole in use; Stand like the legs of a tripod, support each other, and the interaction through horizontal pedal and stay cord, very strong stability had; The time spent does not just fold binding with it, and is easy to carry, deposits and saves the space; Three poles can be processed by steel pipe, and are in light weight.Use horizontal latch that column and vertical rod are connected as one, play the effect of fixedly vertical rod, extracting horizontal latch can be folding with vertical rod, is tied to one with three poles.Draw-in groove on the horizontal pedal in the upper and lower articulates with support hook on second pole and cooperates, and strengthens the stability of first pole and second pole.Backing plate plays the pressure that reduces between pole and the ground, increases the effect of stability.The hook of vertical rod sidepiece is used to hang up kit bag, is convenient to people's work high above the ground.Locating part is a stay cord, and stay cord plays and prevents that first pole, second pole and the 3rd pole from outwards separately causing the effect of slipping.Three square pedals are triangularly arranged, and the operator can do 360 ° turning round on three square pedals, be convenient to carry out work high above the ground, and push rod plays the effect of supporting square pedal.

The utlity model has following advantage: 1, in light weight: than the weight saving 1/3rd of common double ladder; 2, be prone to fold: it is folding that length is all collapsible, and folding back is a bundle steel pipe, and is easy to carry; 3, structure is steady: stand like the legs of a tripod safety and stability when strutting.

Fig. 1 is the structural representation of the utility model.

The specific embodiment

As shown in Figure 1; The collapsible triangle ladder of the utility model comprises that first pole 1, second pole 2, the 3rd pole 3 and fixing and mounting bracket 4, the first poles 1, second pole 2, the 3rd pole 3 process by steel pipe; Fixing and mounting bracket 4 comprises a triangular plate 18; Triangular plate 18 convenient three poles are folding, and triangular plate 18 bottoms are provided with three blocks of fork plates 5, and two blocks of adjacent fork plates 5 are 120 ° of settings.The top of first pole 1, second pole 2, the 3rd pole 3 is hinged with three blocks of fork plates 5 respectively; First pole 1, second pole 2, the 3rd pole 3 are equilateral triangle with the lines of the pin joint of three blocks of fork plates 5 respectively; At least be provided with the folding horizontal pedal 6 of one deck between first pole 1 and second pole 2; First pole 1 and second pole 2 respectively and be provided with a locating part between the 3rd pole 3, locating part is a stay cord 7.Laterally pedal 6 is provided with five layers, and every layer of horizontal pedal 6 processed by angle steel, and an end and first pole 1 are hinged, and second pole 2 is provided with support hook 8, and horizontal pedal 6 bottoms offer with support hook 8 and articulate the draw-in groove 9 that cooperates.Be respectively equipped with a joint push rod 19 on first pole 1 and second pole 2 with on the 3rd pole 3; Be respectively equipped with the square pedal 17 that a tile height equates on every joint push rod 19; Square pedal 17 is positioned at the lower edge of the horizontal pedal 6 of the superiors; Three square pedals 17 are triangularly arranged, and the operator can do 360 ° turning round on three square pedals 17, be convenient to carry out work high above the ground.
