Abstract
The invention discloses folded ladder easy to carry and use, it is the ladder of L including thickness, two sections of cuttings are carried out to ladder, two sections of cuttings ladder has altogether and is cut to three sections, and line of cut crosses the trisection point of ladder center line, to be respectively mounted hinge hinged by three stepladders with another section of destination county of cutting for one section of starting point of cutting wherein, ladder is divided into 3 sections and uses chain connection, when we need not step on it is too high when, two sections therein of expansion is only needed to use, remaining one section keeps flat and play a part of on the ground anti-skidding fixation, simultaneously, storage can be folded up in 3 ends when storage, save space.It is an advantage of the invention that：According to space and the high flexible climbed up can be needed to use, it is easy to operate；Without when can fold up storage, save space.
Description
Technical field
The present invention relates to a kind of ladder, and in particular to folded ladder easy to carry and use.
Background technology
Ladder, daily life toolses do side by two thick bar long, and scansorial cross bar is crossed in centre, for climbing.
Practical double ladder has fixed double ladder and moving herringbone ladder.Fixed double ladder is that people build instrument temporarily；The herringbone of activity
Ladder is that the top of two ladders is connected together with loose-leaf, can altogether, due to its flexibility, therefore extensively when mobile
It is applied in electrician's operation.The double ladder of early stage is usually what timber made, now to utilize aluminium with the development of metal industry more
Alloy material；Aluminium alloy herringbone ladder has light, and attractive in appearance, the characteristics of durable, and cost is not high, therefore is widely used.But, people
Word ladder is larger to floor space demand, therefore, in the place of narrow space, we generally use vertical ladder.
When being ascended a height using vertical ladder, the length of vertical ladder directly affects the height that can be climbed up, but, vertical ladder is more long, vertical ladder frame
If bigger with ground angle afterwards, security is lower, at the same when we need not simultaneously step on to it is too high local when, use inconvenience.
The content of the invention
The technical problems to be solved by the invention are that when being ascended a height using vertical ladder, the length of vertical ladder directly affects what can be climbed up
Highly, but, vertical ladder is more long, and vertical ladder is bigger with ground angle after setting up, and security is lower, when we need not be simultaneously stepped on to too high
It is local when, use inconvenience, it is therefore intended that provide folded ladder easy to carry and use, solution is stepped on safely in small space
Problem high.
The present invention is achieved through the following technical solutions：
Folded ladder easy to carry and use, including thickness is the ladder of L, and two sections of cuttings, described two are carried out to ladder
Section cutting ladder has altogether and is cut to three sections, and line of cut crosses the trisection point of ladder center line, wherein one section of starting point of cutting
Hinge being respectively mounted with the destination county of another section of cutting, three stepladders are hinged.Due to ladder is cut into 3 sections,
The terminal that one section of starting point cut and second segment cut is respectively mounted hinge, i.e. first paragraph and the 3rd stepladder can respectively from two
Individual direction folds to middle that stepladder, ladder is divided into 3 sections and uses chain connection, when we need not step on it is too high when, only
Need to launch two sections therein to use, remaining one section keeps flat and play a part of on the ground anti-skidding fixation, meanwhile, when storage
Storage can be folded up in 3 ends, save space.
The each section of cutting is divided into two steps, and first is formed along cutting for the first time is carried out into A angles with ladder bearing of trend
Tangent plane, A is more than 15 °, and depth of cut is L*csc15 °, and then ladder is carried out second by edge with the first tangent plane into 105 ° of direction again
Secondary cutting forms the second tangent plane, and ladder is cut off, and the line of cut of cutting crosses the trisection point of ladder center line for the first time.Using
The ladder of said structure, when being erected using the angle with 15 ° of angles of vertical line, it is ensured that when two stepladders is erected, cut for the second time
Cut the second cut surface to be formed ladder to erecting common with remaining one section of ladder for keeping flat on the ground and form support, support is more
Plus stabilization.
The cut surface that second cutting is formed is polished, with and the slipmat of form fit is installed replaces polishing
The material for falling.When ladder sets up, the cut surface that second cutting is formed is contacted with ground, is favorably improved by anti-skidding treatment
The security of ladder.
Also it is connected with fastener by lock between every two stepladder.Needing to carry out higher when ascending a height, will latch
It is locked with fastener, it is ensured that the stability of vertical ladder, will not bend in use.
The present invention compared with prior art, has the following advantages and advantages：
1st, present invention folded ladder easy to carry and use, the high flexible that can be climbed up according to space and needs makes
With easy to operate；
2nd, present invention folded ladder easy to carry and use, without when can fold up storage, saving space.

Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
It is limitation of the invention.
Embodiment
As shown in figure 1, present invention folded ladder easy to carry and use, including thickness is the ladder 1 of 10cm 3m long, it is right
Ladder carries out two sections of cuttings, and two sections of cuttings ladder 1 is cut to three sections altogether, and line of cut crosses the trisection of the center line of ladder 1
Point, i.e., the center line 1m long of each stepladder 1, one section of starting point cut and another section of destination county of cutting are distinguished wherein
Hinge 5 is installed three stepladders 1 are hinged.The each section of cutting is divided into two steps：Edge and the bearing of trend of ladder 1 into A angles
Degree carries out first time cutting, and A is more than 15 °, and depth of cut is 10.35cm, and then edge will into 105 ° of direction with the first tangent plane again
Ladder carries out second cutting, and ladder 1 is cut off, and the line of cut of cutting crosses the trisection point of the center line of ladder 1 for the first time.It is right
The cut surface that second cutting is formed is polished, and grinding depth is 0.5cm, with and the slipmat 4 of form fit is installed
Instead of the material for polishing off.Also it is connected with fastener 3 by lock 2 between every two stepladder 1.
Above-described specific embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail, should be understood that and the foregoing is only specific embodiment of the invention, be not intended to limit the present invention
