Description

Reinforced trailer hook Technical Field The utility model relates to the technical field of trailer couplers, in particular to a reinforced trailer coupler. Background The trailer hook is usually arranged at the tail part of the vehicle, mainly plays roles of towing and carrying, and is the most concentrated part of stress in the towing and carrying process. Most of the existing trailer couplers are directly welded at the tail part of a vehicle, and when the trailer couplers are subjected to a heavy load, the fixed mode is characterized in that the trailer couplers are easy to tear and fall from the connection position of the anti-collision beam or deform at the connection point, so that the driving safety of the vehicle can be influenced, and therefore, the reinforced trailer couplers are designed for solving the problems. Disclosure of utility model Aiming at the defects of the existing trailer hook technology, the utility model aims to provide a reinforced trailer hook which has the advantages of improving the connection strength, being convenient to install and the like. In order to achieve the purpose, the technical scheme includes that the reinforced trailer hook comprises a reinforcing beam, triangular reinforcing plates, fan-shaped reinforcing plates, side plates, extension columns, connecting plates, plug brackets and the trailer hook, wherein the side plates are symmetrically welded at two sides of the reinforcing beam, combined positioning holes fixed with a vehicle body are formed in the outer ends of the side plates, the triangular reinforcing plates are welded at connecting included angles of the side plates and the reinforcing beam, two extension columns are symmetrically and fixedly connected in the middle of the reinforcing beam, the fan-shaped reinforcing plates are welded at the connecting positions of the extension columns and the reinforcing beam, the connecting plates are fixedly connected at the outer ends of the two extension columns, the trailer hook is arranged in the middle of each connecting plate, the thickness of each connecting plate is larger than 5mm, and the plug brackets are arranged on the outer sides of any extension columns; When the trailer hook is fixed, the side plate is assembled corresponding to the frame position, and then the high-strength bolt is inserted into the positioning through hole and the opening hole and is in locking connection with the inner side of the vehicle girder; Preferably, one end of the trailer hook is provided with a connecting flange, the other end of the trailer hook is provided with a ball head, and the connecting flange is detachably fixed with the connecting plate through a high-strength bolt; Preferably, one side of the reinforcing beam is also provided with a wire harness buckle fixing bracket; Preferably, the outer sides of the side plates are vertically provided with U-shaped lifting lugs fixed with the vehicle, and the end surfaces of the U-shaped lifting lugs are provided with reinforcing fixing holes; The utility model has the advantages that 1, the high-strength bolts are connected with the vehicle girder, the stress points of the trailer hook and the vehicle can be increased, so that the trailer hook is prevented from tearing and falling from the connecting position of the anti-collision girder under the condition of heavy load, 2, the stress points of the trailer hook are dispersed through the reinforcing cross beam, the triangular reinforcing plate, the sector reinforcing plate, the side plates, the extension column and the connecting plate, so that the force transmission path can be dispersed, the strength of the trailer hook is increased, 3, the trailer hook and the vehicle are positioned and fixed through the combined positioning holes, and a tool is not required to be used for positioning the trailer hook during installation, so that the aim of convenient installation is realized.
