The overall structure diagram for the trailer that example provides；Fig. 3 is the attachment structure schematic diagram of connection handle provided in an embodiment of the present invention.
In a specific embodiment, a kind of trailer is present embodiments provided, specifically, the trailer includes vehicle frame 1, walking
Component, traction piece 2 and elevation and subsidence regulating device 3.
Wherein walking component is for being mounted on vehicle frame 1, to play the role of main support to vehicle frame 1, naturally it is also possible to
It is whole supports.Wherein walking component can be the wheel that 1 left and right sides of vehicle frame and coaxial arrangement are separately positioned on including two,
The center of gravity of vehicle frame 1 is located on the perpendicular where the axis at this time；Wherein walking component can also be including be three in etc.
The wheel of lumbar triangle shape distribution is further added by a wheel in rear side or front side, with shape that is, on the basis of above-mentioned two wheel
Help support；Wherein walking component can also be that the traveling wheel group being arranged including two groups of front and backs, each group traveling wheel group include two
It is separately positioned on the wheel of 1 left and right sides of vehicle frame and coaxial arrangement, totally four wheels are in distributed rectangular.
Wherein traction piece 2 is with pulling equipment for connect, with to the offer tractive force of vehicle frame 1 and steering force, wherein traction piece 2
It is mainly rotatablely connected with pulling equipment around the axis being vertically arranged, so that pulling equipment can not only provide traction piece 2
Forward tractive force, and traction piece 2 can be driven to rotate by own rotation, to drive vehicle frame 1 to rotate, turned to being formed.
Wherein elevation and subsidence regulating device 3 is arranged between vehicle frame 1 and traction piece 2, for adjusting 2 relative frame 1 of traction piece
Height, in new relative altitude, so that new opposite stable relation is kept between vehicle frame 1 and traction piece 2, so that leading
Drawing part 2 can continue to provide tractive force and steering force to vehicle frame 1, while traction piece 2 being made to be adapted to new pulling equipment
Height, be attached with facilitating.It should be noted that wherein the effect of elevation and subsidence regulating device 3 is to tie by itself
Structure adjusts transformation so that traction piece 2 can whole relative frame 1 move up.
In the trailer, when need connect pulling equipment height change when, at this time can not smoothly with traction piece 2
Be attached, at this time can by adjust elevation and subsidence regulating device 3 so that the height of 2 relative frame 1 of traction piece can adjust to
The height of traction piece 2 is corresponding with the height of current pulling equipment, and then can smoothly continue to connect.So in the trailer
In, by the way that elevation and subsidence regulating device 3 is arranged between traction piece 2 and vehicle frame 1, with the height of adjustable 2 relative frame 1 of traction piece
Degree, so that simple adjustment elevation and subsidence regulating device 3, it can so that the height of traction piece 2 is adapted to new pulling equipment, so, it should
Trailer can efficiently solve the current trailer problem bad to the adaptability of pulling equipment.
