[0002] The automotive air conditioning system assembly includes air conditioning pipes, evaporator / condenser cores, air conditioning box assemblies, etc. Each air conditioning assembly requires at least three connecting pipes. Due to the differences in each vehicle model, the thickness of the air conditioning pipes and the thickness and interface size requirements of the pressure plates connecting the two ends are also different, resulting in a wide range of pipe specifications. In addition, to ensure the sealing quality of the pipes, 100% sealing testing must be carried out using corresponding leak detection tools.

[0003] The leak detection tools currently used on site include pipe plugs and pipe buckles. The pipe plugs are mainly used to seal the ends of the pipelines to be inspected, while the pipe buckles are used to clamp and fix the pipelines to be inspected. However, the spacing between the pipe plugs and the pipe buckles in common leak detection tools is fixed, which makes it difficult to adapt to the diverse specifications of air-conditioning pipelines. For example, there are more than 15,000 common air-conditioning pipeline specifications, and the lengths and sizes are also different. Generally, pipe plugs of different lengths and specifications need to be designed specifically. If the outsourcing cost is high, and a large number of tooling racks are required to store a variety of pipe plugs, a large production site will be occupied. More importantly, since there are many varieties of pipe plugs and they are very similar, they can easily be mixed up if you are not careful. It takes a lot of time to find the corresponding tooling when the variety is changed, which affects production efficiency. Utility Model Content
