Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning pipeline detection, and in particular to an adjustable multi-purpose tool for water-tightness detection of air-conditioning pipelines. Background Art

[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

[0031] The following is combined with Figure 1 This application is described in further detail.

[0032] The embodiment of the present application discloses a multi-purpose tool for water-tightness inspection of air-conditioning pipelines. Figure 1 The air-conditioning pipeline sealing water inspection adjustable multi-purpose tool includes a fixed seat 1, a fixed handle 2, a rotating handle 3, a pipeline plug 4, a pipeline buckle 5 and a plug adjusting piece 6. The fixed handle 2 is fixedly installed on one side of the fixed seat 1, and the middle part of the rotating handle 3 is rotatably assembled on the other side of the fixed seat 1. The plug adjusting piece 6 is installed on the fixed seat 1. The pipeline plug 4 is arranged at one end of the plug adjusting piece 6, and the pipeline buckle 5 is vertically fixed to the end of the rotating handle 3. The plug adjusting piece 6 is used to adjust the distance between the pipeline plug 4 and the pipeline buckle 5. Pressing the rotating handle 3 away from the end of the pipeline buckle 5 is used to drive the pipeline buckle 5 to move out of the locking position. The pipeline buckle 5 is a rectangular plate and is opened in a U-shaped notch to adapt to the pipeline to be inspected.

[0033] In this embodiment, the plug adjustment member 6 includes an adjusting screw 61 and a locking nut 62.

[0041] The specific operation method of the multi-purpose adjustable water-tightness inspection tool for air-conditioning pipes in the embodiment of the present application is as follows:

[0042] Press the rotating handle 3 inward to make the pipe buckle 5 deviate from the front of the pipe plug 4, plug the pipe plug 4 and the interface of the inspected pipe into each other, loosen the rotating handle 3, and the pipe buckle 5 will be reset under the action of the elastic reset structure 7, locking the inspected pipe. Then it can be placed in the water tank, start the equipment, and pass 3.5MPa air to maintain the pressure for 1 minute. Observe whether there are bubbles to determine whether the sealing is qualified.

[0043] The beneficial technical effects of the multi-purpose adjustable water-tightness inspection tool for air-conditioning pipes according to the embodiment of the present application are as follows:

[0044] The purpose of adjusting the distance between the pipeline plug 4 and the pipeline buckle 5 is achieved by the plug adjustment part 6, and the locking force can be effectively guaranteed to realize normal leak detection operation. The tooling of the present application can replace at least the original 9 types of tooling, and the service life can be increased from the original 3 months to more than 2 years, which greatly reduces the processing types and quantities of tooling.
