The invention provides a detachable connecting structure and method for an automobile three-way catalytic converter, the detachable connecting structure for the automobile three-way catalytic converter comprises a three-way catalytic converter body, the two sides of the three-way catalytic converter body are both communicated with ventilation pipelines, a preassembled plate is arranged above the ventilation pipelines, a support assembly is arranged at the bottom of the preassembled plate, and the support assembly is arranged above the ventilation pipelines. The surface of the ventilation pipeline is sleeved with a first clamping arm and a second clamping arm, and the top of the first clamping arm is hinged to the top of the second clamping arm. According to the detachable connecting structure and method for the automobile three-way catalyst, when the three-way catalyst is disassembled, the connecting assembly can be conveniently disassembled, so that the ventilation pipeline and the exhaust connecting pipe are separated from each other, and the first clamping arm and the second clamping arm can be rapidly opened through the support assembly; limiting clamping of the first clamping arm and the second clamping arm on the ventilation pipeline is relieved, a worker can take down the three-way catalyst body from the vehicle bottom, and the three-way catalyst body can be disassembled conveniently while it is guaranteed that the three-way catalyst body is firmly installed.

    本发明提供了一种汽车三元催化器的可拆解连接结构及方法,所述汽车三元催化器的可拆解连接结构包括三元催化器本体,三元催化器本体的两侧均连通有通气管道,通气管道的上方设置有预装板,预装板的底部设置有支架组件,通气管道的表面套设有夹持臂一和夹持臂二,夹持臂一和夹持臂二的顶部相互铰接。该汽车三元催化器的可拆解连接结构及方法中,拆解三元催化器时,可方便地拆卸连接组件,使得通气管道和排气连接管脱离接触,通过支架组件可快便快捷地实现夹持臂一和夹持臂二的张开,解除夹持臂一和夹持臂二对通气管道的限位夹持,工作人员可自车底将三元催化器本体取下,在保证三元催化器本体牢固安装的同时,还可方便三元催化器本体的拆解。
