Two roll wheel assemblies 3 put in or stretched out simultaneously relative to mounting seat 2, and adjusting part 4 is provided with two to be parallel to each other, thus by
Two adjusting parts 4 control four rolling component 3, are additionally provided between roll wheel assembly 3 and mounting seat 2 for protecting roll wheel assembly 3
Hold the limit assembly 5 for stretching out or putting in state.
Wherein, the bottom of ladder 1 is provided with four mounting seats 4, and the structure of each mounting seat 4 is identical, and mounting seat 4 is to having
For accommodating the cavity 21 of roll wheel assembly 3 and limit assembly 5, cavity 21 is down-set be used to having for roll wheel assembly 3 put in or
The opening that person stretches out, so realizes that roll wheel assembly 3 can stretch out or put in relative to cavity 21.
As shown in figure 3, the roll wheel assembly 3 for being responsible for stretching out moveable step ladder includes rolling wheel support 31, under rolling wheel support 31
Side is rotatably connected to universal wheel 32, and all directions for causing step ladder equipped with universal wheel 32 can move, 31 turns of rolling wheel support
Dynamic to be connected with adjusting part 4, adjusting part 4 includes adjusting bracket 41, and adjusting bracket 41 and rolling wheel support 31 are rotatablely connected, so
The angle change of adjusting bracket 41 can drive the rotation of rolling wheel support 31, and the end of adjusting rod 42 is in spherical setting, adjusting bracket 41
T-shaped elongated slot 411 is offered on length direction, adjusting rod 42 is connected in T-shaped elongated slot 411 and can slid, and so realizes regulation
Bar 42 and the sliding clamping of adjusting bracket 41, the end that adjusting rod 42 connects control-rod 43 are offered with circular groove, control
Bar 43 connects the end setting spherical in shape of adjusting rod 42, so realizes that adjusting rod 42 is rotatablely connected control-rod 43, as shown in figure 4,
Mounting seat 2 offers through hole 22, and through hole 22 is located at the side of the T-shaped direction of elongated slot 411, and control-rod 43 stretches out from through hole 22, control
Moving horizontally for bar 43 processed can drive moving horizontally for adjusting rod 42, and such adjusting rod 42 slides in T-shaped elongated slot 411, sliding
The rotation of adjusting bracket 41 is driven during shifting, so drives the rotation of rolling wheel support 31, this makes it possible in mounting seat 2
Outside regulation roll wheel assembly 3 puts in or stretched out relative to mounting seat 2.
As shown in figure 4, when roll wheel assembly 3 stretches out relative to mounting seat 2, it is necessary to make roll wheel assembly 3 using limit assembly 5
Stretching state is kept, limit assembly 5 includes the baffle plate 51 that adjusting bracket 41 extends downwardly away from the side of adjusting rod 42, baffle plate 51
Intermittently contradicted with rolling wheel support 31, the madial wall of mounting seat 2 is fixedly connected with gag lever post 52, and gag lever post 52, which is located at, is provided with regulation
The side of bar 42, gag lever post 52 intermittently contradict with rolling wheel support 31, when rolling wheel support 31 and adjusting bracket 41 are in plumbness
When, baffle plate 51 contradicts on rolling wheel support 31 so that the side that rolling wheel support 31 can not face away from adjusting rod 42 is rotated further,
Gag lever post 52 is contradicted on rolling wheel support 31 so that rolling wheel support 31 rotates without the side of normal direction adjusting rod 42, thus by spacing
The collective effect of bar 52 and baffle plate 51 causes rolling wheel support 31 to keep vertical state or take in cavity 21.
As shown in figure 5, the control sleeve 44 that both sides opening is set is provided between two mounting seats 2, the two of control sleeve 44
End is provided with oppositely oriented internal thread, and two control-rods 43 are threaded in the both sides of control sleeve 44 respectively, so rotation
During control sleeve 44, two control-rods 43 are rotated to the direction that control sleeve 44 rotates simultaneously, and two are provided between four mounting seats 2
Individual control sleeve 44, control belt 45, the perisporium of control sleeve 44 and control belt 45 are rotatably connected between two control sleeves 44
Projection 452 is designed with inwall, so increases control sleeve 44 and controls the frictional force between belt 45, prevent control skin
Band 45 rotates, but control sleeve 44 does not have situation about being driven, and the outside of control belt 45 is additionally provided with spacing identical
Grips 451, grips 451 are fixedly connected on the lateral wall of control belt 45, so that the rotation of control belt 45 is more
Add conveniently, so by the rotation of control belt 45, drive the rotation of four control-rods 43 so that 3 same luck of four rolling component
It is dynamic.
When step ladder needs to move, the personnel of ascending a height hold grips 451 and apply active force, rotate control belt 45, together
When drive control sleeve 44 to rotate, the rotation of control sleeve 44 drives the control-rod 43 that is threadedly coupled with it of both sides, control-rod 43
Rotation meeting and mounting seat 2 on through hole 22 between rotate, the movement that such control-rod 43 can be on occurred level direction, to
The direction of control sleeve 44 is moved, and so promotes being displaced outwardly for the horizontal direction of adjusting rod 42, adjusting rod 42 is displaced outwardly that tune can be made
Save support 41 to rotate to vertical direction, while drive the rotation of rolling wheel support 31, rolling wheel support 31 can contradict gag lever post 52, such as
It is that rolling wheel support 31 turns to vertical position that this rolling wheel support 31, which has an active force away from gag lever post 52, when adjusting bracket 41
When on vertical position, the meeting pair roller of baffle plate 51 support 31 has an active force towards gag lever post 52, so that roller
Component 3 stretches out mounting seat 2 so that step ladder conveniently moving, when being moved to required position, then to carry out operation of ascending a height
When, opposite direction rotates control belt 45 so that roll wheel assembly 3 is put in the cavity 21 of mounting seat 2, is ascended a height by mounting seat 2
The support of ladder, simple and convenient and conversion is converted completely between the movement and fixation of such step ladder, will not when step ladder is fixed
It is moved, ensure that the safety for the personnel of ascending a height.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
