Description

Gas tightness test fixture Technical Field The utility model relates to the field of detection tools, in particular to an air tightness testing tool. Background In industrial production, the air tightness test is a core link for guaranteeing the product quality, and is widely applied to the fields of water heating pipelines, gas conveying pipelines, automobile cooling pipelines and the like. Because the pipe fitting structure is various (such as tee bend, cross, direct etc.) and pipe diameter specification are numerous, in order to realize accurate seal and location, need carry out the work piece fixed with the help of rubber positioning seat usually. The existing pipe fitting airtight test tool mostly adopts customized rubber positioning seats, namely, special rubber positioning seats are designed aiming at different types of pipe fittings (such as tee joints and straight-through pipes) and pipe diameter sizes. When the test pipe fitting is replaced, an operator needs to detach and replace the positioning seat, so that the operation is complex, the time consumption is long, positioning inaccuracy is easily caused by installation errors, and the reliability of the airtight test result is affected. Disclosure of utility model The utility model aims to provide an air tightness testing tool, which solves the problem that the conventional air tightness testing tool provided in the background art has a smaller adaptation range of a positioning seat. In order to achieve the purpose, the technical scheme is that the air tightness testing tool comprises a workbench assembled by a bottom plate, a supporting rod, a positioning plate and a sealing mechanism, wherein a plurality of L-shaped plates are slidably arranged at the top of the positioning plate, a support is rotatably arranged on the supporting rod, the support is connected with the L-shaped plates, a turntable is fixedly arranged at the bottom of the support, an anti-falling cap is slidably arranged at the top of the bottom plate through an elastic member, and a plurality of insertion holes for accommodating the anti-falling cap are formed in the periphery of the turntable so that the anti-falling cap is embedded into the insertion holes to limit the turntable. Preferably, the bottom fixed mounting of L shaped plate has the U-shaped piece, the top of positioning disk is equipped with a plurality of be used for holding the spout of U-shaped piece, the connecting rod is installed in the bottom rotation of U-shaped piece, the other end of connecting rod with the support rotates to be connected. Preferably, a rubber pad is fixedly arranged on the side wall of the L-shaped plate. Preferably, the top of the bottom plate is fixedly provided with a vertical rod, the anti-falling cap is slidably arranged on the vertical rod, and the elastic component is a spring sleeved on the vertical rod. Preferably, the top of the turntable is provided with a plurality of through holes. Preferably, the top of the anti-drop cap is fixedly provided with a U-shaped rod. Compared with the prior art, the utility model has the beneficial effects that: according to the air tightness testing tool, the L-shaped plates, the connecting rods, the brackets and the turntables are assembled to form the air tightness testing tool, the distance between the adjacent L-shaped plates is adjustable to adapt to workpieces with different shapes and specifications, and compared with the traditional positioning mode requiring disassembly and reassembly, the air tightness testing tool is simple in structure and convenient to operate, the tool adjusting time is greatly shortened, the testing process is accelerated, and the detection efficiency is improved.
