The invention provides an anti-aging heavy-steam trailer pin handle, relates to the technical field of automobile part machining, and aims to solve the problems that a conventional trailer pin handle is mostly made of cast iron and stainless steel, and cast iron devices are easy to corrode and age, insufficient in rigidity, difficult to bear high-strength traction force, easy to rotate and slip in the use process, poor in service life and the like. The safety protection device comprises a connecting seat, a vehicle pin is vertically and upwards embedded and rotationally mounted at the rear end of the connecting seat; the upper end of the pin is sleeved with a trailer ring; a tray is fixedly installed on the lower portion of the middle of the vehicle pin. The portion, above the tray, of the vehicle pin is sleeved with a spring. And a protective locking sleeve is vertically sleeved on the vehicle pin above the spring in a sliding manner. The connecting base and the automobile pin are both manufactured through semi-solid die casting, the components are composed of 50% of liquid phase and 50% of solid phase, the requirements for high performance and light weight of part products in the automobile industry are particularly met, and the anti-aging agent can be fully fused in the material.
本发明提供抗老化重汽拖车销手柄,涉及汽车零件加工技术领域,以解决常规的拖车销手柄多采用铸铁和不锈钢制成,而铸铁器件不仅易腐蚀老化而且刚性不足,难以承载高强度牵拉力,并且在使用过程中易旋转滑脱,从而造成危险事故的问题,包括连接座;所述连接座的后端垂直向上镶嵌转动安装有车销;所述车销的上端套接有拖车环;所述车销的中部靠下处固定安装有托盘;所述托盘上方的车销上套装有弹簧;所述弹簧上方的车销上竖向滑动套装有保护锁止套。本发明中连接座和车销均采用半固态压铸制成,其中成分为50%液相和50%固相共同组成,特别符合汽车行业对零部件产品高性能和轻量化的要求,并且抗老化剂可充分融于材料中。
