An oil gun is connected with an oiling machine through an oil pipe, an oil outlet pipe of the oil gun is sleeved with a freely-telescopic air bag, the air bag is connected with an air tank through an air pipe, the air tank provides filling gas for the air bag, and the outer diameter of the air bag is larger than the diameter of an automobile oil filling port; a safety cable is arranged between the oil gun and the oiling machine, the end, away from the oil gun, of the safety cable is connected with a valve of the gas tank and an oiling machine oil outlet switch, and the safety cable is shorter than the oil pipe. The device effectively prevents damage to refueling equipment or an automobile after the automobile is started without pulling out an oil gun; the safety cable is linked with an oil outlet switch of the oiling machine, pollution and waste caused by overflow of more oil are prevented, and the labor intensity of accident treatment is reduced; flame-retardant filling gas and an elastic contact push plate are used for preventing oil fire caused by friction in the contact process; the structure is simple, operation is convenient, protection is efficient, and normal refueling work is not affected.
本发明公开了一种防拖拽加油装置,油枪通过油管与加油机连接,油枪的出油管上套设自由伸缩的气囊,气囊通过气管连接为其提供充填气体的气罐,气囊的外径大于汽车加油口的直径;油枪与加油机之间设置安全索,安全索远离油枪的一端连接气罐的阀门和加油机出油口开关,安全索的长度小于油管的长度。该装置有效的防止在未拔出油枪而启动汽车后对加油设备或者汽车的损害;安全索联动加油机的出油口开关,同时防止更多的油溢出造成污染和浪费,降低事故处理的劳动强度;阻燃性的填充气体和弹性接触的推板,防止接触过程中摩擦引发油料起火;结构简单、操作方便、高效防护,且不影响正常的加油工作。
