Abstract
The invention discloses a dual-purpose herringbone ladder which comprises a cylindrical ladder, a grooved ladder, a rotary hinge, a length expansion joint, a fixing rope, a barrier piece and a skid-proof sleeve, wherein the cylindrical ladder is combined with the length expansion joint; the length expansion joint is connected with the grooved ladder through the rotary hinge; when the length expansion joint and the grooved ladder are in the same plane, the cylindrical ladder is inserted into a groove of the grooved ladder; the cylindrical ladder is prevented from moving outside by use of the barrier piece below the grooved ladder, thus a simple herringbone ladder is formed. When the herringbone ladder is to be used, the barrier piece is moved away, the cylindrical ladder is pulled out and forms a certain angle with the grooved ladder through the rotation of the rotary hinge so as to form the herringbone ladder; the length expansion joint is used for maintaining the stability of the herringbone ladder by keeping the cylindrical ladder and the grooved ladder consistent in length, and the fixing rope is used for fixing the two ladders to prevent outward movement of the two ladders, so that the safety is guaranteed.
Description
Technical field
The present invention relates to ladder technical field, specifically a kind of dual-purpose double ladder, can make yi shaped ladder and double ladder and use.
Background technology
At present, in life, mostly use yi shaped ladder and double ladder.Yi shaped ladder can lean against on foreign object, function singleness.Double ladder is fixed without foreign object, and structure is more complicated, and carrying is inconvenient, and cost is higher.People need yi shaped ladder sometimes, sometimes need double ladder, are difficult to when needed find the ladder needing.
Summary of the invention:
Not enough in order to solve in prior art side, the object of this invention is to provide a kind of dual-purpose double ladder, by yi shaped ladder and being combined as a whole of double ladder, both having can be used as yi shaped ladder and used, also can become double ladder and use.
The technical solution adopted in the present invention is: a kind of dual-purpose double ladder, comprises that cylinder ladder, groove are terraced, rotary gemel, length compensation joint, static line, barrier sheet and Anti-slip cover.Cylinder ladder is connected with groove ladder by rotary gemel with length compensation joint combination, length compensation joint.When length compensation joint is with groove ladder at grade time, cylinder ladder is just in the groove of embedded groove ladder, by groove ladder below barrier sheet, stops that cylinder ladder goes out, and forms simple yi shaped ladder.When needs double ladder, barrier sheet is removed, pull out cylinder ladder, rotation by rotary gemel makes the terraced angled double ladder that just forms of cylinder ladder and groove, by length compensation, saved and made cylinder ladder keep double ladder stable consistent with groove ladder length, static line connects two ladders and prevents the outer assurance safety of moving of two ladders.
Outstanding advantages of the present invention is: by groove ladder fluting, makes cylinder ladder when using yi shaped ladder be positioned at groove ladder, reduced ladder volume, and easy to use.When using double ladder, open barrier sheet cylinder ladder is pulled out and can be used, convenient and swift, safety, reduces volume and is convenient to deposit and transport.
Accompanying drawing explanation
The structural representation of Fig. 1 a kind of dual-purpose double ladder of the present invention.
The yi shaped ladder structural representation of Fig. 2 a kind of dual-purpose double ladder of the present invention.
The rotary gemel of Fig. 3 a kind of dual-purpose double ladder of the present invention and length compensation joint package assembly schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described further.
As shown in Figure 1, a kind of dual-purpose double ladder of the present invention, comprises rotary gemel 1, length compensation joint 2, groove ladder 3, static line 4, barrier sheet 5, Anti-slip cover 6 and cylinder ladder 7.Concrete structure and connected mode are: cylinder ladder 7 is connected with groove ladder 3 by rotary gemel 2 with length compensation joint 2 combinations, length compensation joint 2.When length compensation joint 2 is with groove ladder 3 at grade time, cylinder ladder 7 is just in the groove of embedded groove ladder 3, by groove ladder 3 below barrier sheets 5, prevent from stopping preventing that cylinder ladder 7 from going out, and be simple yi shaped ladder like this.
When needs double ladder, barrier sheet 5 is removed, pull out cylinder ladder 7, rotation by rotary gemel 1 makes that cylinder ladder 7 and groove ladder 3 are angled just forms double ladder, by length compensation, save 2 and make cylinder ladder 7 keep double ladder stable consistent with groove ladder 3 length, static line 4 connects two ladders and prevents the outer assurance safety of moving of two ladders.Anti-slip cover 6 is enclosed within the bottom of groove ladder 3.
Claims (5)
1. a dual-purpose double ladder, comprise cylinder ladder, groove ladder, rotary gemel, length compensation joint, static line, barrier sheet and Anti-slip cover, it is characterized in that, described cylinder ladder and the combination of length compensation joint, length compensation joint is connected with groove ladder by rotary gemel, when length compensation saves with groove ladder at grade, cylinder ladder is just in the groove of embedded groove ladder, by groove ladder below barrier sheet, stop that cylinder ladder goes out, form simple yi shaped ladder, when needs double ladder, barrier sheet is removed, pull out cylinder ladder, rotation by rotary gemel makes the terraced angled double ladder that just forms of cylinder ladder and groove, static line connects two ladders to be prevented from moving outside two ladders.
2. a kind of dual-purpose double ladder according to claim 1, is characterized in that, described groove ladder is that a side is opened reeded ladder.
3. a kind of dual-purpose double ladder according to claim 1, is characterized in that, described length compensation joint is connected with cylinder ladder and rotary gemel, and while guaranteeing work, cylinder ladder is identical with groove ladder length.
4. a kind of dual-purpose double ladder according to claim 1, is characterized in that, described barrier sheet is positioned on groove ladder, prevents that cylinder ladder skids off when yi shaped ladder is worked.
5. a kind of dual-purpose double ladder according to claim 1, is characterized in that, when described static line is worked at double ladder, connecting cylinder ladder and groove ladder, guarantee that between two ladders, angle is certain.
