The invention relates to the technical field of automobile fuel tanks, and particularly discloses a mechanical sealing device for an automobile fuel tank, which comprises a connecting body connected with the automobile fuel tank and a sealing assembly rotationally connected with the connecting body and used for sealing the connecting body, the sealing assembly comprises a fixing block fixedly connected to one side of the connecting body, a rotating shaft arranged in the fixing block, a steering piece matched with the rotating shaft and used for changing steering, a first sealing body connected with the rotating shaft and a second sealing body connected with the steering piece, and the steering directions of the first sealing body and the second sealing body are opposite. Mounting bodies are symmetrically and fixedly connected to the bottom of the connecting body, connecting rods are symmetrically and fixedly connected to the positions, corresponding to the mounting bodies, of the first sealing body, arc-shaped rods are arranged between the connecting rods and the mounting bodies, moving plates connected with the arc-shaped rods are arranged on the mounting bodies, pulling ropes are fixedly connected to one sides of the moving plates, and wires of the pulling ropes reach the inner wall of the connecting body through the mounting bodies. And an annular groove is formed in the inner wall of the connecting body. The problem that a traditional oil tank cover is poor in sealing effect is solved.

    本发明涉及汽车油箱技术领域,具体公开了一种汽车油箱用机械密封装置,包括与汽车油箱连接的连接体和与连接体转动连接的用于封闭连接体的密封组件,密封组件包括固接在连接体一侧的固定块、设置在固定块内的转动轴、与转动轴配合用于改变转向的转向件、与转动轴连接的第一密封体和与转向件连接的第二密封体,第一密封体和第二密封体的转向方向相反,连接体的底部对称固接有安装体,第一密封体对应安装体的位置对称固接有连接棒,连接棒与安装体之间设有弧形棒,安装体上设有与弧形棒连接的移动板,移动板的一侧固接有牵引绳,牵引绳的走线经安装体到达连接体的内壁,连接体的内壁开有环形槽,本装置解决了传统的油箱箱盖密封效果差的问题。
