The utility model content
The utility model has overcome that the hook and the adapter plate of towing hook snaps inefficacy easily behind the existing automobile; There is the deficiency of potential safety hazard in towing hook behind the automobile in the process of using; Towing hook behind a kind of automobile is provided; The stable welding of its hook and adapter plate is reliable, is difficult for snapping inefficacy, and towing hook is safe in utilization behind the automobile.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: towing hook behind a kind of automobile comprises adapter plate and is welded on the hook on the adapter plate; Said adapter plate comprises substrate, welded plate; Connect through connecting panel between substrate and the welded plate, substrate, connecting panel, welded plate link together stepped, and substrate is provided with the installation via hole; Hook takes the shape of the letter U; The hook comprise the preceding welding section of open end, away from the back welding section of open end, preceding welding section is welded on the substrate, back welding section is welded on the welded plate.The preceding welding section of hook and back welding section respectively with substrate and the welded plate weld together of adapter plate, take the shape of the letter U and link up with, so be equivalent to have four welding regions.Near towing hook behind the automobile is installed via hole, increase the welding region of hook and adapter plate,, reduce back towing hook work deflection, improve service life to reduce the acting force arm when the work of towing hook behind the automobile.Four are disperseed and autotelic welding region has been practiced thrift welding cost to the utmost, have satisfied back towing hook integral intensity and deformation requirements again.Hook is reliable with the stable welding of adapter plate, is not prone to the situation of snapping inefficacy, makes behind the automobile use of towing hook safer.Substrate is provided with the installation via hole, and on automobile, change and safeguard by easy disassembly through bolted connection for towing hook behind the automobile.
As preferably, said substrate, connecting panel and welded plate are all rectangular, and said substrate, connecting panel and welded plate are structure as a whole, and the bending angle of said connecting panel and substrate and welded plate all is the right angle.Substrate, connecting panel and welded plate are structure as a whole has increased the rigidity of adapter plate.
As preferably; Before the preceding welding section of said hook and back are provided with between the welding section and connect welding section and back welding section and and the bending section of their integrative-structures; Preceding welding section, bending section, back welding section link together and are stepped appearance, and bending section and preceding welding section all are the obtuse angle with the bending angle of back welding section.Step-like hook has improved the non-deformability of hook.
As preferably, the both sides of said adapter plate are provided with flange.Flange has increased the rigidity of adapter plate.
As preferably, the connection location of the connection location of said substrate and connecting panel and connecting panel and welded plate is provided with plurality of strengthening ribs.Reinforced rib has increased the intensity of whole adapter plate, makes adapter plate not yielding.
As preferably, the mouth of hook position, rear end of said hook is to the top of welded plate perk camber.The perk of arc has made things convenient for articulating of hook attachment for trailer.
Compared with prior art, the beneficial effect of the utility model is: the stable welding of the hook of towing hook and adapter plate is reliable behind (1) automobile, is difficult for snapping, and towing hook is safe in utilization behind the automobile; (2) towing hook passes through bolted connection on automobile behind the automobile, disassembling, assembling and replacing and easy to maintenance; (3) near towing hook behind the automobile is installed via hole, increase the welding region of linking up with adapter plate, reduced the acting force arm of towing hook when work behind the automobile, reduced back towing hook work deflection, improved service life.
