Description
Technical field
The utility model belongs to building implements technical field, be specifically related to a kind of collapsible, lengthen double ladder.
Background technology
Ladder is the equipment that building field often uses, mainly comprise single ladder and double ladder, existing double ladder is normally by hinged for the top of two single ladders, during use, two single ladders are outwards rotated, forms double ladder, in use, if the fracture of hinged place, top, double ladder just there will be and collapses, and causes injury to personnel.
In addition, when existing double ladder is in closure state, two single ladders are states bonded to each other, and workman, when carrying mobile double ladder, holds residence too wide, easily causes hand fatigue, carrying inconvenience.
Moreover existing double ladder is general lower, when needs work aloft, long ladder can only be used.
Utility model content
The purpose of this utility model is to provide a kind of collapsible, double ladder of lengthening, effectively can avoid the risk collapsed, and can lengthen and use as long ladder.
The technical scheme that the utility model adopts is: collapsible, lengthen double ladder, comprise the main ladder of hollow and the pair ladder of the hollow hinged with main terraced top, also safety rope is provided with between main ladder and pair ladder, one end of safety rope is provided with weight, the one end being connected with weight penetrates in main ladder, and the other end of safety rope penetrates secondary ladder and is connected on the hook that arranges in secondary ladder.
Feature of the present utility model is also,
The width of secondary ladder is not more than the width of main ladder.
The cross section that pin stepped on by main ladder first is the round rectangle vertically placed.
The second cross section stepping on pin on secondary ladder is the round rectangle laterally placed.
Main terraced top is provided with articles holding table, and secondary terraced top is provided with angle bar.
Articles holding table upper surface is provided with slipmat.
The beneficial effects of the utility model are: trestle ladder structure that is collapsible, that lengthen of the present utility model is simple, easy to use, the setting of safety rope, the main ladder on both sides and pair ladder is made to there is the risk that collapses, add the safety of use, and safety rope can be accommodated in main ladder and pair ladder easily, is convenient to deposit, and beautiful and clean; First steps on the setting that pin and second steps on pin, saves material and cost, alleviates weight, is convenient to carrying; The top of main ladder is provided with articles holding table, is convenient to ladder in use place tool.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in detail.
The utility model provide a kind of collapsible, lengthen double ladder, as shown in Figure 1, comprise main terraced 1 of hollow and the pair ladder 2 of the hollow hinged with main terraced 1 top, safety rope 5 is also provided with between main terraced 1 and pair ladder 2, one end of safety rope 5 is provided with weight 7, the one end being connected with weight 7 penetrates in main terraced 1, and the other end of safety rope 5 penetrates secondary ladder 2 and is connected on the hook 8 of setting in secondary ladder 2, as shown in Figure 2.
The width of secondary ladder 2 is not more than the main width of terraced 1.
As shown in Figure 3, the first cross section stepping on pin 4 on main terraced 1 is the round rectangle vertically placed.
As shown in Figure 4, the second cross section stepping on pin 3 on secondary ladder 2 is the round rectangle laterally placed.
As shown in Figure 5, main terraced 1 top is provided with articles holding table 9, and secondary terraced 2 tops are provided with angle bar 6.
As shown in Figure 6, articles holding table 9 upper surface is provided with slipmat 10.
During use, as shown in Figure 7, main terraced 1 and pair ladder 2 are moved round about, make to form certain subtended angle between winner's ladder 1 and pair ladder 2, until the weight 7 of safety rope 5 one end and the inwall close contact of main terraced 1, safety rope 5 is in tensioned state, and now, the utility model just can use as normal double ladder by user; The safety rope 5 tightened make main terraced 1 of both sides and pair ladder 2 can not there is the risk that collapses, add the safety of use.
When the position needing climbing higher, first the hook 8 of safety rope 5 from secondary ladder 2 is taken off, then main terraced 1 and pair ladder 2 are pulled open to level, angle bar 6 now on secondary ladder 2 is stepped on pin with first of main terraced 1 upper end and is contacted, as shown in Figure 8, now, the utility model just can use as vertical ladder by user.
When needing to pack up when finishing using, as shown in Figure 5, secondary ladder 2 is promoted towards the main direction of terraced 1, because the main width of terraced 1 is greater than the width of secondary ladder 2, so secondary ladder 2 can embed in main terraced 1, like this, double ladder edge after packing up is narrower, holds more convenient, laborsaving when carrying is mobile; And now weight 7 draws safety rope 5 under gravity and hangs down and become owner of in the die cavity of terraced 1 column, such safety rope 5, when double ladder is packed up, is just accommodated in the main ladder of double ladder and pair ladder is inner easily, is convenient to deposit, neat and artistic.
Wherein, the on main terraced 1 first cross section stepping on pin 4 is the rectangle vertically placed, and bearing capacity is strong, the user being applicable to body weight heavier tramples ascending stair, the second cross section stepping on pin 3 on secondary ladder 2 is the rectangle laterally placed, and bearing capacity is general, is suitable for the light people of body weight and uses, the advantage of such setting is, without the need to by both sides or certain on one side trample that post does too thick, save material and cost, weight reduction simultaneously, be convenient to carrying, and expand use crowd scope.
Articles holding table 9 is for workman at top place tool, and slipmat 10 can prevent instrument from sliding on double ladder and dropping from double ladder.
By the way, double ladder that is collapsible, that lengthen of the present utility model effectively can avoid the risk collapsed, and can lengthen as long ladder use.Trestle ladder structure that is collapsible, that lengthen of the present utility model is simple, and easy to use, the setting of safety rope, makes the main ladder on both sides and pair ladder there is the risk that collapses, add the safety of use; First steps on the setting that pin and second steps on pin, saves material and cost, alleviates weight, is convenient to carrying.
