Description

Technical Field

[0001] The utility model relates to a towing hook assembly, belonging to the technical field of automobile trailers. Background Art

[0002] The tow hook assembly needs to be installed at the front or rear end of the car, and is mainly used to tow faulty vehicles and RVs. Existing tow hooks are usually directly fixed on the rear anti-collision beam of the car, and the vehicle to be towed is hung on the tow hook by hanging.

[0003] When the trailer hook is towing, if the road is bumpy or uphill, there is no locking mechanism between the hook and the trailer hook, and the closure is not tight, so it is easy to fall off from the opening of the trailer hook, making it impossible to tow the trailer normally. In order to solve the above problem, a blocking member is usually set on the trailer hook. When the towed vehicle or RV is hooked on the trailer hook, the blocking member closes the opening of the trailer hook to prevent the trailer from being unhooked during travel.

[0004] However, the existing blocking member is usually locked by a torsion spring, that is, one end of the existing blocking member is hinged to the trailer hook, and the other end thereof presses the end of the opening of the trailer hook under the elastic force of the torsion spring, thereby closing the opening. When there are steep uphill and downhill slopes or bumpy roads, the blocking member may still be unhooked due to the large impact it receives, making it very inconvenient to use. Utility Model Content
