Description
Technical field
The utility model relates to double ladder field, especially a kind of contraction type double ladder.
Background technology
The ladder of ascending a height is the conventional instrument of people's routine work and life, and current ladder is made up of two crosspieces between stock and stock mostly, and the length of stock cannot regulate; During use, ladder needs one to have one shot or certain stationary support could use, when cannot use without when support as support.Market has occurred that human body is carried, although it solve the problem not needing support, its length is still fixing for this reason, carries and uses extremely inconvenience.
Utility model content
The utility model aims to provide a kind of contraction type double ladder easy to use.
For achieving the above object, the utility model provides following technical scheme: contraction type double ladder, comprises telescopic ladder, section of ladder, rotating shaft and latch, and described telescopic ladder has two, is connected between two telescopic ladders by rotating shaft; Described section of ladder is located on telescopic ladder, and this section of ladder comprises terraced leg, crosspiece, top jack and bottom jack, and described terraced leg top is provided with crosspiece; Described terraced leg is also provided with top jack and bottom jack.
As further scheme of the present utility model: described terraced leg is provided with two, is symmetrical arranged.
As further scheme of the present utility model: described section of ladder is provided with several, wherein every two adjacent section of ladders are connected by latch.
As further scheme of the present utility model: described latch is Demountable.
As further scheme of the present utility model: described top jack is positioned at the outside of cross bar.
As further scheme of the present utility model: described bottom jack is located at bottom terraced leg.
Compared with prior art, the beneficial effects of the utility model are: this contraction type double ladder, forms telescopic ladder by several section of ladder, achieves the Telescopic of double ladder, and can regulate double ladder height by changing section of ladder quantity, easy to use; When not in use, just can section of ladder be folded together after latch is pulled out, by rotating shaft, two telescopic ladders can also be folded, reduce the volume of double ladder greatly, easy to carry.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model;
Fig. 2 is the overall schematic of section of ladder.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, in the utility model embodiment, contraction type double ladder, comprises telescopic ladder 1, section of ladder 2, rotating shaft 3 and latch 4, and described telescopic ladder 1 has two, connected by rotating shaft 3 between two telescopic ladders 1, two telescopic ladders 1 are folded by rotating shaft 3, unites two into one, easy to use, be applicable to multiple environment for use, and be convenient to transport; Described section of ladder 2 is located on telescopic ladder 1, and this section of ladder 2 comprises terraced leg 201, crosspiece 202, top jack 203 and bottom jack 204, and described terraced leg 201 has two, is symmetrical arranged, and terraced leg 201 top is provided with crosspiece 202; Described terraced leg 201 is also provided with top jack 203 and bottom jack 204, this top jack 203 is positioned at the outside of cross bar, and bottom jack 204 is located at bottom terraced leg 201; Described section of ladder 2 is provided with several, can arrange according to real needs, the height of change ladder that can be convenient, flexible, wherein every two adjacent section of ladders 2 are connected by latch 4, adjacent section of ladder 2 cooperatively interacts, the top jack 203 of the bottom jack 204 being positioned at the section of ladder 2 of top and the section of ladder 2 that is positioned at below coordinates, and the top jack 203 of the bottom jack 204 that latch 4 inserts the section of ladder 2 of top and the section of ladder 2 that is positioned at below is inner, is coupled together by adjacent two section of ladders 2; Described latch 4 is Demountable, just can adjacent two section of ladders 2 be folded together after pulling out latch 4, terraced leg 201 diameter of the section of ladder 2 on upper strata is less than terraced leg 201 diameter of the section of ladder 2 of lower floor, when folding, the terraced leg 201 of the section of ladder 2 on upper strata inserts in the terraced leg 201 of the section of ladder 2 of lower floor, thus shorten the length of ladder, be convenient to transport.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
