Abstract

The invention provides a trailer towing hook structure which is applied to the technical field of trailers and is characterized in that a towing vehicle connecting column (1) of the trailer towing hook structure is arranged at the rear part (4) of a towing vehicle, a trailer connecting column (2) is arranged at the front part (5) of the trailer, the rear part (4) of the towing vehicle is provided with a first telescopic cylinder (8), the surface of the towing vehicle connecting column (1) is provided with a first annular groove (10) along the periphery of the surface of the towing vehicle connecting column (1), and a first positioning screw (11) penetrating through a first telescopic rod (9) of the first telescopic cylinder (8) is arranged to be of a structure capable of penetrating through a first threaded hole in a connecting column sleeve piece (3) to extend into the first annular groove (10). The trailer towing hook structure is simple in structure and low in cost, hooking connection of a towing vehicle and a trailer can be conveniently and rapidly achieved, the stress is reliable when a tractor drags the trailer to run, falling is not prone to occurring, the traction hook is convenient to take down when the tractor and the trailer are separated, and convenience and safety in use are improved.

Description

Technical field [0001] The present invention belongs to the technical field of trailer, and more specifically, it is related to a tractor traction structure. Background technique [0002] In large vehicle fields such as trucks, traction hooks are required to be trailer and tractor and tractor connections. The traction hooks in the prior art are either complicated, costly, either simply, but the power is poor, easy to fall off, and not to disassemble, not meet the demand. Inventive content [0003] The technical problem to be solved by the present invention is: aiming at the shortcomings of the prior art, there is a simple structure, low cost, convenient and quick and easy to realize the hook connection of the tractor and the trailer, and the tractor is reliable when traction the trailer. The traction hook is convenient when the traction, tractor and trailer are separated, and the traction hook structure of the trailer traction of the convenience and safety of the use is improved...
