Frame 2, the ladder chair frame 2 include bottom plate 21, and the front surface of the bottom plate 21 and the front surface of bearing plate 14 are hinged by hinge 3,
It is connected with left plate 22 on the left of bottom plate 21, right side plate 23, the left plate 22 and the right side plate 23 are connected on the right side of bottom plate 21
Between be connected with several level boards 24, table on the vertical range between 21 bottom surface of bottom plate and 22 upper end of left plate and bearing plate 14
Vertical range between face and ground matches.
The front end of terraced chair frame 2 and the front end of bearing plate 14 are hinged by several hinges 3, enable terraced chair frame 2 along 3 axis of hinge
Line rotates 180 °, and when terraced chair frame 2 is placed on bearing plate 14, several level boards 24 in terraced chair frame 2 make for storage archives
With extending trolley archiving space, make staff that can disposably carry more archives, improve space utilization
Rate；
When archives need to be placed on higher document shelf by staff, it can will be placed on terraced 2 upper end archives of chair frame and turn
It puts to the archives loading plate 11 of vehicle frame 1, terraced chair frame 2 is then rotated 180 ° along 3 axis of hinge, at this time left plate 22 and right side
The upper end and ground face contact, 21 bottom surface of bottom plate and 14 upper surface of bearing plate of plate 23 are in same plane, and terraced chair frame 2 is inverted, in vehicle frame 1
Front end form a firm terraced chair, can not only be trampled for staff, staff is facilitated to take on higher document shelf
Archives are put, the interim seat of staff is also used as, the use when needing to read archives provides temporary rest, alleviates
The fatigue of staff substantially increases the comfort for arranging archives work；Terraced chair frame 2 can realize that archives are deposited in different conditions
It puts, three kinds of functions of ladder and chair, killing three birds with one stone increases the diversity of trolley function, achieves significant beneficial effect.
Fixed device 4, the rear table of the right side plate 23 are connected between 1 front end of rear surface and vehicle frame of the left plate 22
Fixed device 4 is connected between 1 front end of face and vehicle frame, the fixed device 4 includes fixing buckle pedestal 41, fixing buckle 42, fixes
Protrusion 43, the fixing buckle pedestal 41 is mounted on the rear surface of left plate 22 and right side plate 23, sets on the fixing buckle pedestal 41
There is the fixing buckle mounting hole through left and right sides, the fixing buckle 42 includes two connecting rods 421, mounting post 422 and connection
One end of column 423, two connecting rods 421 is detachably connected by mounting post 422, and the other end of two connecting rods 421 passes through company
The connection of column 423 is connect, the fixing buckle 42 is fitted to fixing buckle pedestal 41 by mounting post 422 and the fixing buckle mounting hole
On, the fixed lobe 43 is mounted on the front end of vehicle frame 1, and fixed lobe 43 is equipped with the groove matched with connecting column 423.
One end of two connecting rods 421 is detachably connected by mounting post 422, and connecting rod 421 is facilitated to be mounted on fixing buckle pedestal
On 41, the connecting column 423 of fixing buckle 42 and the groove on fixed lobe 43 cooperate, when being placed on terraced chair frame 2 on bearing plate 14,
Terraced chair frame 2 and vehicle frame 1 are securely connected, is prevented when staff pushes trolley mobile, terraced chair frame 2 is revolved due to inertia force
Then the archives being stored in terraced chair frame 2 is caused to be scattering into ground；Structure is simple, stable connection, easy to operate.
The left front end of the left plate 22 and the right front ends of right side plate 23 are equipped with anticollision device, collision-prevention device 25, the anticollision device, collision-prevention device 25
Anti-collision air bag or anticollision cavernous body can be used, when terraced chair frame 2 is unexpected to collide with foreign object, anticollision device, collision-prevention device 25 is effectively relieved
The impact force of collision reduces the damage of terraced chair frame 2 or document shelf, plays a good protective effect.
The upper end of the left plate 22 and right side plate 23 is equipped with anti-skid rubber cushion 26, and anti-skid rubber cushion 26 not only increases
The height of terraced chair frame 2, the setting for consolidating terraced chair frame 2 after 180 ° of rotation on the ground, while playing effective anti-skidding work
With, improve staff work when safety.
The rear and front end of the level board 24 is equipped with baffle 241, when preventing staff from pushing trolley mobile, storage
Archives in terraced chair frame 2 are scattering into ground due to inertia force.
It is connected with several reinforcing ribs 15 between the bottom of the bearing plate 14 and the front surface of vehicle frame 1, improves bearing plate 14
Bearing capacity, it is compact-sized, ensure that the stability of equipment entirety.
There are gaps for the rear end of the ladder chair frame 2 and 1 front surface of vehicle frame, execute spinning movement convenient for terraced chair frame 2, reduce ladder
Frictionally damage between chair frame 2 and vehicle frame 1.
The hand-pushing handle 12 has inclined radian rearwardly and upwardly, and staff is facilitated to apply motive force, knot to trolley
Structure is more humanized.
The rear surface of the vehicle frame 1 is equipped with several storage bags 16 to be made for sundries such as staff's holding water cup, pen, paper
The function of trolley has more diversity, improves the working efficiency of staff.
When in use, in the normal state, terraced chair frame 2 is placed on bearing plate 14 device, is used for archiving, archives
It is stored on level board 24, when baffle 241 effectively prevent staff to push trolley mobile, the shelves that are stored in terraced chair frame 2
Case since inertia force is scattering into ground, reinforced with vehicle frame 1 and connected, further prevented in staff by fixed device 4 by terraced chair frame 2
When pushing trolley mobile, terraced chair frame 2 causes the archives being stored in terraced chair frame 2 to be scattering into ground since inertia force rotates
Face；
When archives need to be placed on higher document shelf by staff, it will be placed on terraced 2 upper end archives of chair frame first
It relays to the archives loading plate 11 of vehicle frame 1, while the connecting column of fixing buckle 42 423 being separated with the groove of fixed lobe 43,
So that fixed device 4 is failed, terraced chair frame 2 is then rotated 180 ° along 3 axis of hinge, at this time the upper end of left plate 22 and right side plate 23
With ground face contact, in same plane, terraced chair frame 2 is inverted, is formed in the front end of vehicle frame 1 for 21 bottom surface of bottom plate and 14 upper surface of bearing plate
One firm terraced chair, can not only trample for staff, facilitate staff to pick and place archives on higher document shelf, may be used also
Using the seat interim as staff, the use when needing to read archives provides temporary rest, alleviates the tired of staff
Labor substantially increases the comfort for arranging archives work；Archive arrangement work is carried out when staff needs to continue to move to trolley
When making, terraced chair frame 2 need to only be rotated to initial position, and connecting column 423 is caught in again in the groove of fixed lobe 43
The terraced chair frame 2 of realization is fixedly secured with vehicle frame 1, and terraced chair frame 2 can continue to use for archiving at this time；Terraced chair frame 2 is in different shapes
State realizes three kinds of archiving, ladder and chair functions, and killing three birds with one stone increases the diversity of trolley function, achieves aobvious
The beneficial effect of work.
For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with
In the case where spirit, changes, modifications that embodiment is carried out, replacement and variant still fall within protection scope of the present invention it
It is interior.
