Description

Hinge connection structure Technical Field The utility model relates to a hinged connection structure, and belongs to the technical field of mechanical equipment. Background The hinge is to movably connect two objects, and the two objects are in conditional relative movement with each other by keeping partial freedom of movement, so that the hinge is a common mechanical connection mode. In the practical application process, the hinge between the straight connecting piece 1 and the H-shaped connecting piece 2 is commonly encountered, as shown in fig. 1, the current conventional practice is to open a connecting hole on the H-shaped connecting piece, insert a pin shaft in the connecting hole, and arrange a sleeve on the straight connecting piece 1, and sleeve the sleeve on the pin shaft to complete the hinge connection of the two. The conventional hinged connection structure needs to process connecting holes, sleeves and pin shafts, and is high in processing procedures, materials and cost, and not suitable for mass production. Therefore, there is a need for a new hinge connection structure that is simple in structure and low in cost, and reduces the manufacturing cost of the device. Disclosure of Invention The utility model aims to overcome the defects and provide a novel hinged connection structure with simple structure and low cost, and the manufacturing cost of equipment is reduced. The purpose of the utility model is realized in the following way: A hinged connection structure comprises a straight connecting piece and an H-shaped connecting piece, wherein an integrally formed T-shaped connector is arranged on the straight connecting piece, a connecting through hole is formed in the H-shaped connecting piece, connecting parts movably connected with the connecting through hole are arranged at two ends of the T-shaped connector, and cylindrical bosses movably embedded into the connecting through hole are arranged at the connecting parts. Further, the T-shaped connector is integrally formed by injection molding of engineering plastics. Further, the engineering plastic is glass fiber reinforced nylon. Further, the two sides of the T-shaped connector are provided with reinforcing sheet layers, and the reinforcing sheet layers and the connecting part are provided with conical surface structures for transition. Further, the cylindrical boss of the connecting part is replaced by a threaded counter bore, and the connecting part is movably connected with the connecting through hole through a bolt and the threaded counter bore. Further, two connecting portions of the T-shaped connector are provided with a cylindrical boss, and the other connecting portion is provided with a threaded counter bore. Compared with the prior art, the utility model has the beneficial effects that: The utility model adopts the T-shaped connector with the T-shaped structure as the main structure of the hinged connection, and the connecting parts are arranged at the two sides of the T-shaped connector and are movably connected with the H-shaped connecting piece, so that the hinged connection structure is simplified, the assembly is convenient, the cost is low, and the utility model is suitable for mass production.
