For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below will knot
Close the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.Implement it should be noted that described embodiment is only a part of the present invention
Example rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under not making creative work premise, broadly falls into
The scope of protection of the invention.
Embodiment
Refer to Fig. 1 and Fig. 2, embodiments provide a kind of scissor-type ladder, including
At least two scissor unit；Each scissor unit includes the first scissor 1 and the second scissor 2；
First scissor 1 is centrosymmetric structure, the first scissor 1 include first high foot-operated 4, the
One low foot-operated 3 and the first connecting portion of being connected between first high foot-operated 4 and first low foot-operated 3
5, first high foot-operated 4 low with first foot-operated 3 be arranged in parallel, and first high foot-operated 4 is positioned at a high position,
First low foot-operated 3 is positioned at low level, and the first high foot-operated 4 and first low end of foot-operated 3 is equipped with
Hinge hole, the middle part of the first connecting portion 5 is provided with the first spacing articulated section 6；
Second scissor 2 is centrosymmetric structure, the second scissor 2 include second high foot-operated, second
Low foot-operated and be connected to second high foot-operated and second low foot-operated between the second connecting portion, second is high
Foot-operated ride low with second be arranged in parallel, and the second high riding is positioned at a high position, and the second low riding is positioned at
Low level, the second high riding is equipped with hinge hole with the second low foot-operated end, the second connecting portion
Middle part is provided with the second spacing articulated section；
In the middle part of first connecting portion 5 of one the first scissor 1 with the second of second scissor 2 even
Connect in the middle part of portion by first spacing articulated section 6 and second one scissor of the hinged composition in spacing articulated section
Unit, and when first high foot-operated 4, second high foot-operated, first low foot-operated 3 and second low foot-operated
When being placed in horizontal position, the first spacing articulated section 6 offsets with the second spacing articulated section；At least two is cut
Fork unit is connected with each other, and the first of the first scissor 1 of superposed scissor unit is low by foot-operated 3
High with the second of the second scissor 2 of the scissor unit being positioned at bottom foot-operated hinged；Superposed
Second low riding of the second scissor 2 of scissor unit is cut with the first of the scissor unit being positioned at bottom
It is hinged that first height of fork 1 rides 4.
The maximum advantage of the present invention is portability, the characteristic of product whole utilization scissors mechanism,
Can fold layer by layer, finally be reduced to the size of a traveling bag, be can be placed in traveling bag to carry
The ladder carried.
First scissor 1 and the second the most symmetrical parts of scissor 2.When organizing work,
Be positioned at bottom the first scissor 1 first high foot-operated 4 with the of superposed second scissor 2
Two is low foot-operated horizontally overlapping, forms one grade of complete riding.In like manner, it is positioned at the second of bottom to cut
Fork 2 second high foot-operated with the first of superposed first scissor 1 low foot-operated 3 also level weights
It is stacked one grade to ride.Operating personnel just rides the most upwards along every grade when climbing
Climbing, the method for use is as good as with common ladder.First spacing articulated section of the first scissor 1
6 and second second spacing articulated section of scissor 2 offset when ladder is fully deployed, thus
Limit further rotating between the first scissor 1 and the second scissor 2, ensure that ladder is in work
During stability.
Material for the first scissor 1 with the second scissor 2 is not defined, can be according to work
Occasion select different raw material, the lightest solid highstrenghtpiston or insulating properties attractive in appearance
Strong solid wood etc., therefore not to repeat here.
As preferably, the two ends of described first scissor 1 and the second scissor 2 are equipped with fillet.By
This avoid using during scratching to human body, prevent injured.
As preferably, the bottom surface of described first scissor 1 and the second scissor 2 is equipped with rubber cushion.By
Likely occur shearing in ladder the first scissor 1 and second scissor 2 during storage folds
Danger, the most preferably bottom surface at the first scissor 1 with the second scissor 2 sets rubber cushion and protects.
As preferably, the first connecting portion 5 of described first scissor 1 and first high foot-operated 4 and the
One low foot-operated 3 is obliquely installed；Second connecting portion of described second scissor 2 and second high foot-operated and
Second high riding is obliquely installed.Under this scheme, the first scissor 1 and broken line of the second scissor 2
Structure is more mild, helps the whole height of ladder when lowering storage.
And as another kind of preferred version, the first connecting portion 5 and first of described first scissor 1
High foot-operated 4 and first low foot-operated 3 are vertically arranged；Second connecting portion of described second scissor 2 with
Second height is foot-operated and the second high riding is vertically arranged.Under this scheme, when ladder is organized work
A junction 5 can be the most vertically superposed with the second connecting portion, can reduce consumptive material, and increase is ridden
Width.
Above two scheme is actual there is no dividing of quality, can need freely select according to design.
As preferably, described first spacing articulated section 6 is fan-shaped flange, and fan-shaped circle centre position is provided with
Hinge hole；Described second spacing articulated section is fan-shaped flange, and fan-shaped circle centre position is provided with hinge hole；
When first high foot-operated 4, second high foot-operated, first low foot-operated 3 and second low foot-operated be placed in level
The fan-shaped flange of fan-shaped flange side and the second spacing articulated section of the first spacing articulated section 6 during position
Side offsets.
The effect of the first spacing articulated section 6 and the second spacing articulated section is the first scissor 1 and
Two scissors 2 spacing hinged, prevents the first scissor 1 and the second scissor 2 360 ° without limitation
Hinged.And the preferred version used in the present invention is to be made in the first articulated section and the second articulated section
For fan-shaped flange, one-body molded with the first scissor 1 and the second scissor 2 respectively, processing is once
Put in place.
A kind of scissor-type ladder that the present invention provides, can save parking space with stored collapsed,
Being more convenient for, it is mobile to carry, and is particularly suited for the occasion needing frequent ladder to move, the body after folding
Actively it is tiny, it might even be possible to puts into and carries inside traveling bag.And product integrated operation letter
Single, it is possible to safe spacing, thus high safety.Meanwhile, product structure is simple, and component is few,
The lightest.
Embodiment described above only have expressed one embodiment of the present invention, and its description more has
Body is with detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.Should refer to
Go out, for the person of ordinary skill of the art, before without departing from present inventive concept
Putting, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.
Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
