Abstract
A convenient ladder is formed by overlapping at least two sectional ladder units, wherein each ladder unit comprises two tubular vertical rods and at least two cross rods which are fixed between the two vertical rods in a crossing manner; the two ends of the vertical rod are respectively a big end and a small end; in two adjacent ladder units, the small head end of one ladder unit can be inserted into the large head end of the other ladder unit; and a sleeving and locking structure is arranged between the large head end and the small head end of the adjacent ladder units. Therefore, when in use, the ladder units can be increased or decreased at any time according to the requirements to achieve the required length of the ladder, thereby achieving the purpose of convenient use; in addition, the utility model can be disassembled when not in use so as to be convenient for carrying, carrying and storage, therefore, the structure of the utility model is more reasonable.
Description
Technical field
The utility model relates to a kind of ladder.
Background technology
We are at ordinary times when using ladder, often can run into ladder otherwise oversize vertical not, or the too short situation that cannot use.In addition, we know that oversize ladder had not only been not easy to daily carrying and has carried, but also is not easy to storage and deposits.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of more reasonable structure, carries and carry and collect convenient ladder easily.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of convenient ladder, it is overlapped by least two segmented ladder unit and forms, described ladder unit include two tubuloses montant and across at least two cross bars be fixed between this two montant; Described montant two ends are stub end and little head end respectively; In adjacent two ladder unit, the little head end of one of them ladder unit can be inserted into the stub end of another ladder unit; And be provided with socket latch-up structure between the large and small head end of adjacent ladder unit.
In the improvement project to above-mentioned convenient ladder, described socket latch-up structure is latch, chaining or hook.
Compared with prior art, the beneficial effects of the utility model are: because it is overlapped by least two segmented ladder unit to form, just can increase and decrease ladder unit so in use as required at any time to reach desired ladder length, reach object easy to use; In addition, just it can be split when not using and come, carry and collect so that carry, therefore more reasonable structure of the present utility model.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Accompanying drawing explanation
Fig. 1 is the decomposing schematic representation of the utility model embodiment.
Detailed description of the invention
The utility model is a kind of convenient ladder, and as shown in Figure 1, it is overlapped by least two segmented ladder unit 1 and forms, described ladder unit 1 include two tubuloses montant 11 and across at least two cross bars 12 be fixed between this two montant 11; Described montant 11 two ends are stub end 111 and little head end 112 respectively; In adjacent two ladder unit 1, the little head end 112 of one of them ladder unit 1 can be inserted into the stub end 111 of another ladder unit 1; And between the large and small head end 111,112 of adjacent ladder unit 1, be provided with socket latch-up structure 2, cause danger to prevent adjacent ladder unit to disconnect in use.As can be seen from above, because this ladder adopts multiple ladder unit to be socketed to form one by one, just can increase and decrease ladder unit so in use as required at any time to reach desired ladder length, reach object easy to use; In addition, just it can be split when not using and come, carry and collect so that carry, therefore more reasonable structure of the present utility model.
Described socket latch-up structure 2 can be latch, chaining or hook etc., as long as can prevent disconnection from causing danger, conveniently lock again, unlocking when overlapping or split ladder unit.
Although reference above embodiment describes the utility model in detail, but be it will be apparent to one skilled in the art that by the disclosure, and when not departing from principle of the present utility model and the scope of described claim restriction, can make a variety of changes the utility model or revise.Therefore, the detailed description of disclosure embodiment is only used for explaining, instead of is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
