[0002] A leak detector is an instrument for detecting liquid or gas leaks in pipelines or containers. It is an ultra-sensitive combustible gas leak detector that uses the detection principle of semiconductors. It is more suitable for finding and detecting the location of micro-leaks of combustible gas. It is compact, easy to operate, and convenient to carry. It comes with a flexible probe that feels comfortable. After the leak detector is processed as a finished product, its gooseneck tube needs to be tested for curvature.

[0003] When the gooseneck of a leak detector is subjected to a bending fatigue test, the leak detector is usually fixed with bolts to ensure that the position of the leak detector is locked during the swing test. Since the bolts need to be rotated before and after the test, it is inconvenient. Therefore, a locking structure for the bending fatigue test of the gooseneck of a leak detector is needed, which can quickly disassemble and assemble the leak detector and the fatigue test device, thereby improving the convenience of the bending fatigue test of the gooseneck of the leak detector.

[0024] Figure 1-3The present invention shows a locking structure for a gooseneck bend endurance test of a leak detector according to an embodiment of the present invention, which includes an I-shaped plate 1: a slide rail 2, a slider 3 and a cross plate 4 are provided on the outer side of the I-shaped plate 1; a motor 5 is fixedly installed on the surface of the I-shaped plate 1 by bolts; the output shaft of the motor 5 passes through the I-shaped plate 1 and is fixedly connected to a rotating plate 6 by a flange; a support rod 7 is connected to the surface of the rotating plate 6 and the cross plate 4 through a rotating shaft; a splint 8 is welded to the surface of the cross plate 4; a bottom plate 11 is provided below the I-shaped plate 1; a turntable 12 is installed on the top of the bottom plate 11 and is rotatably connected to a rocker arm 14; the bottom plate 11 and the rocker arm 14 are rotatably connected to each other.
