Pull and set between limiting plate of the structure including being located at the upper tubing string both sides respectively, two pieces of limiting plates on described
There is the stud through the upper tubing string, and be provided with to be located on the downside of the upper tubing string between two pieces of limiting plates and pull plate, institute
State to pull to be respectively equipped between plate and two pieces of limiting plates and pull block and be connected；The upside of the upper tubing string is provided with upper bracket, institute
The two ends for stating upper bracket are respectively provided with the spacing side for preventing that the limiting plate from rotating around the stud axis；It is described spacing
Plate is provided with anti-rotating hole, and the stud is provided with the anti-rotation section coordinated with the anti-rotating hole.
Further, neck is correspondingly provided with the both sides side wall for pulling block, the plate that pulls is provided with and the neck
The bayonet socket of cooperation, and the side wall of the neck and described pull are correspondingly provided with screw mounting hole between plate.
Further, the bayonet socket is in splayed, and the width of the bayonet socket points to the side of lower tubular column along the upper tubing string
To being gradually reduced.
Further, the anti-rotating hole and anti-rotation section are in the quadrangle cooperated.
The beneficial effects of the utility model are：
Stable collapsing structure from steering wheel two of the present utility model to regulation, by lower collapsing structure set interference match somebody with somebody
Upper tubing string, lower tubular column and the crumple bushing closed, when by a certain degree of axial force, upper tubing string, lower tubular column and crumple bushing
Between can be achieved crumple；Spacing matching relationship is set between the upper bracket in structure and limiting plate by being pulled by, simultaneously
Matching relationship between stud and limiting plate is set to anti-rotation structure, plate is pulled by non axial in this way, can be prevented effectively from
During power produce rotation caused by pull block be broken and can not crumple, increase the uniformity of tubing string crumple.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing is illustrated：
Fig. 1 is structural representation of the utility model steering wheel two to the stable collapsing structure embodiment of regulation；
Fig. 2 is Fig. 1 axonometric drawing；
Fig. 3 is the structural representation for above pulling structure.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model can be better understood from and can be practiced, but illustrated embodiment is limited not as to of the present utility model.
As shown in figure 1, for structural representation from the utility model steering wheel two to the stable collapsing structure embodiment of regulation.
The steering wheel two of the present embodiment including lower collapsing structure and above pulls structure to the stable collapsing structure of regulation.Lower collapsing structure
Including upper tubing string 1, lower tubular column 2 and crumple bushing 3, the interference fit of lower tubular column 3 is sleeved on the lower end of crumple bushing 3, and crumple bushing 3
Upper end interference fit be sleeved in tubing string 1.
Structure is pulled on the present embodiment to be included respectively being located between the limiting plate 4 of the upper both sides of tubing string 1, two pieces of limiting plates 4
Plate 6 is pulled provided with being provided with to be located on the downside of upper tubing string 1 between the stud 5 through upper tubing string 1, and two pieces of limiting plates 4, plate 6 is pulled
