For realizing above-mentioned purpose; The telescoping vehicle towing hook of the utility model; Be equipped with on car body, comprise the car puller hook that has crook, cooperate the shock absorber that links to each other with car body; When it received external force and have the motion opposite with vehicle heading at car puller hook, described shock absorber was that car puller hook provides the elastic force opposite with this sense of motion;
Inhibiting device, it cooperates with car body and links to each other, and when car puller hook received the application force along the vehicle direct of travel, described inhibiting device limited the relative car body of car puller hook moving along the vehicle direct of travel.
As qualification to aforesaid way; Described shock absorber comprises the sleeve that is connected with car body, the back-up ring that is connected with the rigidly connected pipe link of car puller hook, with pipe link; In sleeve, be provided with the one-level spring; Receive external force and when having the motion opposite with vehicle heading, described pipe link drives back-up ring and in sleeve, slides at car puller hook, and the one-level spring is applied thrust through back-up ring.
As improvement to aforesaid way, in sleeve, with the one-level spring altogether line of centers be provided with the two-level spring that the tail end with sleeve is connected, the length of described two-level spring is less than the one-level spring.
As improvement, be provided with the pilot bar that cooperates with the pipe link plug-in mounting that connects back-up ring at the sleeve internal fixation to aforesaid way.
As qualification to aforesaid way, the line of centers setting altogether of described pilot bar and one-level spring.
As qualification to the utility model; Described inhibiting device comprise the limiting bracket that is connected with car body, with the rigidly connected swivel nut of car puller hook; When car puller hook receives the application force along the vehicle direct of travel, described limiting bracket through with contact matching restriction car puller hook the moving of swivel nut along the vehicle direct of travel.
As the qualification to the utility model, described car body is the longeron of vehicle frame.
Adopt technique scheme,, make car puller hook receive external force and when having the motion opposite with vehicle heading through shock absorber; For car puller hook provides the elastic force opposite with this sense of motion, like this, when not using car puller hook; Can through set up on the bumper/spoiler one with bumper/spoiler on the hole passed of the confession car puller hook that the is provided with buckle that carries out spiral-lock car puller hook is headed into the inside that bumper/spoiler contains, improve integral aesthetic property, and when using car puller hook; Only need buckle is deducted, car puller hook can eject under the effect of shock absorber outside the bumper/spoiler, at this moment; Because the effect of inhibiting device makes car puller hook and car body relative fixed, realize the trailer effect; In addition, when bumping, because the effect of this shock absorber has reduced the injury of car puller hook to human body, its integral structure is simple.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify:
Fig. 1 is the utility model telescoping vehicle towing hook integral structure scheme drawing.
Among the figure: the 1-car puller hook; The 2-limiting bracket; The 3-swivel nut; The 4-pipe link; The 5-back-up ring; 6-one-level spring; The 7-two-level spring; The 8-pilot bar; The 9-sleeve; The 10-longeron.
The specific embodiment
The telescoping vehicle towing hook of the utility model; Comprise car puller hook 1 that has crook and shock absorber and the inhibiting device that matches with car puller hook 1; Shock absorber cooperates with car body and links to each other; When car puller hook 1 receives external force and has the motion opposite with vehicle heading, for car puller hook 1 provides the elastic force opposite with this sense of motion; Inhibiting device and car body cooperate and link to each other, and when car puller hook 1 received the application force along the vehicle direct of travel, described inhibiting device limited car puller hook 1 relative car body moving along the vehicle direct of travel.
