The invention provides a leakage alarm mechanism for oil and gas transportation, and relates to the field of leakage alarm, the leakage alarm mechanism comprises a pull piece, the pull piece is of an inverted U-shaped structure, each movable guide ring is connected with a driving displacement plate through two pull plates, the outer end of each driving displacement plate is of a wedge-shaped structure, and an auxiliary rod is arranged in the middle of the outer end of each driving displacement plate; the outer side of each auxiliary rod is sleeved with a spring. During use, the pulling piece is pulled to ascend, the spring on the outer side of the auxiliary rod can stretch, the driving displacement plate is pulled to move outwards, the driving displacement plate conducts guiding displacement in the driving groove, the stress push rod is stressed to move downwards, and the contact piece makes contact with the upper portion of the oil tank truck. The contact fixing effect is improved, and the problem that when an existing leakage alarm mechanism is used, bumping and vibration can be generated due to the fact that a transport vehicle is in a continuous moving state, and the alarm mechanism is prone to loosening is solved.

    本发明提供一种油气运输用泄露报警机构,涉及泄漏报警领域,包括:拉件,所述拉件为倒U形结构,每个移动导环通过两个拉板连接有一个驱动位移板,驱动位移板的外端为楔形结构,每个驱动位移板的外端中间位置设有一个辅助杆,每个辅助杆的外侧套装有一个弹簧。使用的时候,拉动拉件上升,使辅助杆外侧的弹簧可以伸展,拉动驱动位移板向外移动,使驱动位移板在驱动槽的内部导向位移,使受力推杆受力向下移动,使接触件与油罐车上方接触,由于接触件为橡胶材质,使其与油罐车防滑平稳接触,提高接触固定效果,解决了现有的泄露报警机构在使用的时候,由于运输车辆处于持续移动的状态,会产生颠簸以及振动,容易导致报警机构产生松动的问题。
