Now portable multi-function carrier loader application method provided by the invention is described below：
User can select the state of this portable multi-function carrier loader according to the size of cargo.When cargo size compared with
When big, big vehicle body state as shown in Figure 1 may be selected, at this moment cargo can be placed on to front frame 1 and overlay 2 surface of Rear frame
Foldable skewback 12 on, and using vehicle body expansion device for quickly disassembling 17 so that front frame 1 and Rear frame 2 is maintained at same level
Highly, specific method is the outer of the vehicle body expansion Quick Release axis 32 being fixed on the movable end for linking up with 33 in front frame 1 or Rear frame 2
It holds at ailhead.Cargo slides because of vibration when transporting in order to prevent, can be adjusted using lower link bar device for quickly disassembling 15
Position of the lower link bar 14 on sliding rail 16, specific method is that Quick Release rotates by a certain angle 28, to make Quick Release on 28
Boss leaves rubber sheet gasket 31 and lower link bar Quick Release axis 29, and at this moment lower link bar Quick Release axis 29 will be in relaxed state, then
Lower link bar 14 is moved to the outer ledge of cargo along sliding rail 16, is later rotated back Quick Release to original position 28, from
And boss thereon is utilized to clamp rubber sheet gasket 31 and lower link bar Quick Release axis 29, at this moment lower link bar 14 can consolidate cargo
It lives calmly.When needing to adjust the height of telescopic lever 9, the cross bar on elastic force bar 11 can be grasped and then firmly pulled up,
During this, the upright bar on elastic force bar 11 will be slided along the guide groove being oriented on card 27, while the horizontal hook on elastic force bar 11 will
Can because elastic force bar 11 integrally-built cross-direction shrinkage due to be separated from limit hole in a certain spacing card 10, later by upper connecting rod 25
It is moved up or down in the inner wall of lower pull rod 26 to desired position, then unclamps hand, at this moment the cross on elastic force bar 11
Hook will reenter under elastic force bar 11 resilient force of itself in the limit hole in another spacing card 10, is achieved in and stretches
The change of 9 height of contracting pull rod.When needing to unload cargo from eminence, foldable skewback 12 can be unfolded and by around small auricle
13 rotation modes its rear end is put in eminence, at this moment the cargo of eminence i.e. by foldable skewback 12 it is convenient and strength-saving be unloaded to
On this portable multi-function carrier loader.
When cargo size is smaller, small vehicle body state as shown in Figure 2 may be selected.First by Rear frame 2 together with thereon
Foldable skewback 12 downwardly turns on the bottom surface for overlaying front frame 1 after 180 °, then vehicle body is utilized to fold device for quickly disassembling 18
Front frame 1 and Rear frame 2 are fixed together, specific method is the ailhead clamped with finger on vehicle body folding Quick Release axis 34, is made
Pin 35 on its end and end is passed through from the strip preformed hole in the middle part of the back-end framework of Rear frame 2 on bottom surface, then
It is rotated by 90 °, at this moment pin 35 will be blocked by strip preformed hole, and vehicle body, which is thus folded Quick Release axis 34, using pin 35 fixes
Firmly.And vehicle body when needing for small vehicle body state to be launched into big vehicle body state folds 18 unlocking method of device for quickly disassembling antithesis.So
Universal wheel 6 is rotated by a certain angle by wheel shaft locking device 4 afterwards, specific method is that rear wheel bar 7 is pulled outward with hand, to make
Spring 22 in tightening state is further shunk, and at this moment the shank of the key position on wheel shaft 21 will move and be detached from unlocking outward
Flower trough on ladle heel block 19, is rotated by 90 ° or 180 ° forward or backwards later, and hand is unclamped, under the tensioning force effect of spring 22,
The shank of the key position on wheel shaft 21 turns again in the flower trough of locked iron block 19 and is stuck in two opposed slots, and at this moment wheel shaft 21 is
It is locked.Under small vehicle body state, this portable multi-function carrier loader climbs building better performances.In addition, the angle of triangle wheel 3
Method of adjustment is also the same.It, can will be foldable oblique in addition, when needing to unload cargo from the front frame 1 in small vehicle body state
Panel 12 is unfolded and its rear end is placed on ground, you can achievees the purpose that facilitate unloading.
When not using this portable multi-function carrier loader usually, folding as shown in Figure 3 can be fully folded as
State, specific method be with hand by telescopic lever 9 around the rotation of big auricle 8 to being bonded with 1 surface of front frame, and according to the method described above
Triangle wheel 3 and universal wheel 6 are rotated by a certain angle by wheel shaft locking device 4.In a folded configuration, this portable more work(
Energy carrier loader can save parking space.
