Embodiment 2
With reference to shown in Fig. 3, a kind of ladder that the utility model embodiment two is provided, including at least two groups ladder modules 100.
It should be noted that the structure of ladder module 100 in the present embodiment, operation principle and technique effect and embodiment
The structure of the ladder module 100 in, operation principle are identical with technique effect, may be referred to the corresponding contents in embodiment one,
It is not described in detail herein.
One group of first connecting portion of ladder module 100 111 in the ladder in two adjacent groups ladder module 100 with another group
The second connecting portion 112 of ladder module 100 is rotatably connected.Here it should be understood that two in same ladder module 100
One connecting portion 111 is rotatably connected with two second connecting portions 112 in another group of ladder module 100 respectively.
It should be noted that described being rotatably connected refers to that two groups of adjacent ladder modules 100 have and keep phase herein
To fixed first state, and the second state that two groups of adjacent ladder modules 100 can be relatively rotated.
When two groups of adjacent ladder modules 100 are in first state, one group of ladder in two adjacent groups ladder module 100
First ratchet clamping part 113 of module 100 is intermeshed and tight fit with the second ratchet clamping part 114 of another group of ladder module 100, this
When, two adjacent groups ladder module 100 can not be relatively rotated, and the first ratchet clamping part 113 is intermeshed with the second ratchet clamping part 114
So that the adjacent more difficult relative rotation of two groups of ladder modules 100.
When two groups of adjacent ladder modules 100 are in the second state, one group of ladder in two groups of adjacent ladder modules 100
First ratchet clamping part 113 of submodule group 100 is separated from each other with the second ratchet clamping part 114 of another group of ladder module 100, now adjacent
Two groups of ladder modules 100 can be rotated in certain angular range.
Also, it should be noted that one group of first connecting portion of ladder module 100 in two groups of adjacent ladder modules 100
111 can be bolted with another group of second connecting portion of ladder module 100 112, it is also possible to be connected by bearing pin.Use
During bolt connection, it is possible to use nut is fastened so that first connecting portion 111 is fitted with second connecting portion 112, and nut can be selected
Butterfly nut, butterfly nut convenient disassembly, it is not necessary to can just be tightened using other instruments or unscrewed.Can certainly be first
The internal thread that the external screw thread of bolt coordinates is arranged in through hole on connecting portion 111 and second connecting portion 112.
Ladder has deployed condition (as shown in Figure 3) and contraction state (as shown in Figure 4).
When ladder is in contraction state, the first support of one group of ladder module 100 in two adjacent groups ladder module 100
Part 11 and another group of doubling of the first support member 11 of ladder module 100.In the present embodiment, when ladder is retracted to limiting condition,
First support member 11 of two adjacent groups ladder module 100 is substantially parallel and two ends are substantially flush；Ladder also is understood as to be retracted to
During limiting condition, the angle between the first support member 11 of two adjacent groups ladder module 100 is 0 °.Ladder makes in contraction state
The entire length for obtaining ladder is shorter, thus facilitates and places, and occupies little space, and also facilitates and carries.
When ladder is in deployed condition, the first support of one group of ladder module 100 in two adjacent groups ladder module 100
There is angle between part 11 and another group of the first support member 11 of ladder module 100.In the present embodiment, when ladder is in the limit
During deployed condition, the angle between the first support member 11 of two adjacent groups ladder module 100 is 220 °.Certainly, two adjacent groups are worked as
When angle between first support member 11 of ladder module 100 is 180 °, ladder is yi shaped ladder (as shown in Figure 5).When using, can
To adjust the angle between two adjacent groups ladder module 100 as needed.Using more convenient.
The ladder module 100 of one end of ladder is the first ladder module 101, the ladder of the other end of ladder in the present embodiment
Module 100 is the second ladder module 102, and one end away from the second ladder module 102 of the first ladder module 101 can be provided with anti-
Saddle 15, Non-slip material 15 be fixed on the first support member 11 of the first ladder module 101 away from the one of the second ladder module 102
End.One end away from the first ladder module 101 of second ladder module 102 can also set Non-slip material 15, and Non-slip material 15 is fixed
In one end away from the first ladder module 101 of the first support member 11 of the second ladder module 102.Non-slip material 15 can increase ladder
Son and contact surface between frictional force, it is to avoid when in use between ladder and ground or ladder between the walls produce skidding show
As.
In the present embodiment, the first support member 11 of the first ladder module 101 includes the first support body 115 and regulation
Part 116, the slidable connection of 116 and first support body of regulating part 115.When the first support body 115 is hollow structure,
Regulating part 116 can be arranged in the first support body 115；Cunning can certainly be set in the first support body 115
Groove, regulating part 116 is arranged in chute.Regulating part 116 is scalable relative to the first support body 115, that is, using ladder
When, if bottom surface sections are smooth, can be by adjusting regulating part 116 so that ladder is steady.The support body of regulating part 116 and first
Can be fixed by screw between 115, when screw lock, regulating part 116 can not be slided relative to the first support body 115
Dynamic, when screw unclamps, regulating part 116 can be slided relative to the first support body 115.
The outside of the first support member 11 of the second ladder module 102 can also set hook 16, and when using, ladder has to be hung
Upward, hook 16 can be used to suspended item, such as kit bag etc. for one end of hook 16, when aloft operation, can be work
Tool is all placed in kit bag, it is to avoid upper and lower ladder fetching tool back and forth, and larger convenience is brought to operation.
It should be noted that the first support member 11 of the first ladder module 101 and the second ladder module 102 is respectively provided with freedom
End, free end can be not provided with first connecting portion 111 or second connecting portion 112.
Also, it should be noted that ladder can not only be launched into the state of " one " font, ladder can also be launched into other
State, now has angle between the first support member 11 of two adjacent groups ladder module 100, the angle of angle can be as needed
Regulation.As shown in fig. 6, ladder can be from medium position bending so that into " people " font, can thus work as double ladder makes ladder
With；Ladder can also be bent into " U " word, and the ladder of this state, two free ends are placed on the ground, thus be can be used to
Do drying frame and dry thing or for doing rack stacked items.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
