Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model
Fig. 2 and Fig. 3 is the structure diagram that the utility model is connected with frame-steering frame.
Embodiment
The embodiment of the utility model is described in detail below in conjunction with attached drawing.
As shown in Figure 1, the structure of the present embodiment includes traction bar body 1, telescopic rod 2 and air bag 3, the traction bar body
1 includes extension sleeve 11, back 13 and bottom plate 14, and 11 both sides of extension sleeve connect one end of back 13, back 13 respectively
The other end is connected between two backs 13 to pivotally connected frame bogie 4, the bottom plate 14, and the outside of bottom plate 14 is equipped with an adjustable plate
15th, 15 upper surface of adjustable plate connects the air bag 3, and the air bag 3 is connected with frame-steering frame 4, and the telescopic rod 2 is arranged on
In extension sleeve 11.
In the present embodiment, one end hinged with frame-steering frame 4 on the back 13 is folded upward at, and is divided on two bending parts
Not She You a through hole, and two through hole is coaxial, bolt 16 is equipped with the through hole, to be connected with the journal stirrup on frame-steering frame 4.
In the present embodiment, the adjustable plate 15 is arranged on bottom plate 14 on 13 bending part side of back, the air bag 3
Downside is fixedly connected with adjustable plate 15 and frame-steering frame 4 respectively, and air bag 3 is located on rear side of 13 bending part of back, makes traction
The bolt 16 of 13 bending part of bar body 1, air bag 3 and back forms lever construction.
In the present embodiment, the 14 triangle structure of back 13 and bottom plate, the extension sleeve 11 are arranged on triangle
The apex of shape structure, 11 axis of extension sleeve is perpendicular to bottom plate 14.
In the present embodiment, 11 side wall of extension sleeve is equipped with a through hole, and a spacer pin 12, institute are equipped with the through hole
State it is axially distributed on telescopic rod 2 have multiple through holes, the spacer pin 12 can pass through any through hole on telescopic rod 2, will
Extension sleeve 11 and telescopic rod 2 lock.
The operation principle of above-mentioned draw bar assembly is as follows：
2 front end of telescopic rod connects tractor, according to tractor species and actual shipment operating mode, can adjust telescopic rod 2
Extension elongation, and locked telescopic rod 2 and extension sleeve 11 by spacer pin 12.
In said structure, 13 rear end of back is bolted with frame-steering frame 4, forms hinge, enables back 13
Enough to be rotated around bolt in perpendicular, then back 13, hinge joint and adjustable plate 15 form lever construction.
When carrying out the flexible adjustment of telescopic rod 2, the spacer pin 12 on extension sleeve 11 is first removed, if necessary to stretch
Bar 2 forward extends out, then deflates to air bag 3, and air bag 3 compresses after deflating, and according to lever principle, adjustable plate 15 moves upwards,
1 front end of traction bar body moves downward, i.e. 11 front end of extension sleeve tilts down, then under the action of 2 gravity of telescopic rod, work
Personnel can be easier telescopic rod 2 pulling out one end distance from extension sleeve 11, so that telescopic rod 2 extend out to required length,
Spacer pin 12 is inserted into lock telescopic rod 2 and extension sleeve 11.This mode is equally applicable to need to take the entirety of telescopic rod 2
Situation about going out.
If desired telescopic rod 2 is then inflated air bag 3, expands air bag 3, adjustable plate 15 is applied to after-contraction
Downward pressure, according to lever principle, 1 front end of traction bar body is then moved upwards, 11 front end of extension sleeve is inclined upwardly,
Under the action of 2 gravity of telescopic rod, staff can be easier telescopic rod 2 being pushed into extension sleeve 11, so that telescopic rod 2 is received
Required length is reduced to, spacer pin 12 is inserted into and locks telescopic rod 2 and extension sleeve 11.
It these are only the preferred embodiment of the utility model, be not intended to limit the present invention, for this area
Technical staff for, various modifications and changes may be made to the present invention.Where within the spirit and principles of the present invention,
Any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
