Abstract

The invention discloses a rear trailer hook device for an airport trailer, and relates to the technical field of towing hook devices. The device includes a body. The first passage and the second passage are respectively arranged on the inner two sides of the trailing hook device. The first passage and the second passage have the same structure, one side of the first passage and one side of the second passage are respectively provided with a first engaging groove and a second engaging groove, and the other side of the first passage and the other side of the second passage are respectively provided with a first mounting port and a second mounting port. On the one hand, the trailer is connected by one end of the third trailer chain, the other end of the third trailing chain is connected withone end of the first trailing chain and the second trailing chain. When the trailer is moved forward, the trailing hook device simultaneously provides pulling force for the third trailing chain through the first trailing chain and the second trailing chain. The first trailing chain and the second trailing chain are uniformly forced, and the overall pulling efficiency is much higher than that of the conventional trailing hooks.

Description

technical field [0001] The invention relates to the technical field of tow hook devices, in particular to a rear tow hook device for an airport trailer. Background technique [0002] The decoupling device is generally a tow hook, also called a tow ball and a tow bar, etc. The tow hook is widely used for towing RVs, yachts, beach motorcycles, RVs, bicycles, storage boxes, etc., and the tow hooks of trailers used in airports The device is usually installed at the rear of the car. The trailer device is generally fixed on the tow hook of the trailer and the towed vehicle through the trailer tow rope, and is driven by the front vehicle to be moved by the trailer. However, the overall trailer effect of the current decoupling device is not good, because the power of the trailer is concentrated on A tow rope is not only easy to cause wear and tear after long-term use, and has potential safety hazards, but also the decoupling device bears all the pulling force when towing the vehicle...
