The invention provides a car coupler supporting cover connecting structure which comprises a car coupler mounting base, a long-strip-shaped protrusion is arranged in the middle of the lower side of a lower plate of the car coupler mounting base, and a hole used for mounting a second car coupler pin is formed in the portion, in the middle of the protrusion, of the car coupler mounting base. After the second coupler pin penetrates through the coupler mounting seat, the lower bolt extends out of the outer side of the coupler mounting seat; a hole is formed in the middle of the coupler supporting cover, the coupler supporting cover is fixed to the lower side of the coupler mounting base, the lower bolt penetrates through the hole in the middle of the coupler supporting cover and then is provided with the slotted nut, and the slotted nut is in a loose state enabling the coupler pin to rotate freely. According to the coupler pin bolt, the requirement for convenient installation of an existing vehicle structure can be met, meanwhile, the problems of abrasion and fatigue of an original coupler pin bolt are solved, positioning and the freedom degree are considered, and force for limiting axial rotation of a coupler pin in an original bolt structure is released.

    本发明提供一种车钩托盖连接结构,包括车钩安装座,车钩安装座下板下侧中部设有长条状的凸起,凸起中部位置的车钩安装座上设有用于安装第二车钩销的孔,其特征在于,还包括车钩托盖、第二车钩销,第二车钩销下端带有下部螺栓,第二车钩销穿过车钩安装座后,下部螺栓伸出车钩安装座外侧;车钩托盖中部设孔,固定在车钩安装座下侧,下部螺栓穿过车钩托盖中部孔后安装开槽螺母,开槽螺母处于使车钩销可自由转动的松弛状态。本发明该发明具有能够满足既有车辆结构便捷的安装性,同时,解决了原有车钩销螺栓磨损和疲劳的问题,兼顾了定位和自由度,释放了原有螺栓结构中限制车钩销轴向旋转的力。
