[0002] A house refers to a construction building for people to live, work, study, produce, operate, entertain, store goods and carry out other social activities. During the use of the house, water, electricity and gas are needed. When water is used, pipes need to be laid. After long-term use, pipes will leak. Since the pipes are all inside the wall, they need to be detected by detection devices.

[0003] In the prior art, the leakage point is detected by a leakage detector and a sound wave stethoscope is used to detect the leakage point. The closer to the leakage point, the larger the sound wave generated, and the signal reception is determined by the detector.

[0004] In the current prior art, since the probe position is held by hand during operation, the detection point cannot be accurately determined along the direction of signal increase through multiple comparisons, which affects the detection efficiency and is inconvenient to operate. Therefore, a leakage detection device is proposed to address the above problems. Utility Model Content

[0007] The positioning structure comprises a sliding sleeve, which is vertically arranged to penetrate the sliding hole. A rotating seat is rotatably mounted on the bottom end of the sliding sleeve, and a suction cup is fixed on the bottom end of the rotating seat.

[0008] Preferably, a fixing plate is fixed to the middle of the suction cup.

[0009] Preferably, a limiting ring is sleeved on the outer side of the top of the sliding sleeve, and the area of ​​the limiting ring is larger than the area of ​​the fixed plate, which can ensure that the pressing is more accurate when the positioning structure is rotated.

[0010] Preferably, a resistance ring is fixed on the bottom inner wall of the sliding sleeve, a piston rod is inserted into the interior of the sliding sleeve in the vertical direction, a piston is fixed to the bottom end of the piston rod, the piston is offset on the bottom side of the resistance ring, and the piston area is larger than the hollow area of ​​the resistance ring.

[0011] Preferably, the outer diameter of the piston is smaller than the inner diameter of the sliding sleeve, and the diameter of the piston rod is smaller than the inner diameter of the resistance ring, so that when the piston is pressed, air can quickly enter the suction cup to release the adsorption operation.

[0012] Preferably, a support ring is fixed on the top inner wall of the sliding sleeve, and a spring is fixedly connected between the support ring and the extrusion cap, which can cooperate with the suction cup to allow air to enter and release the adsorption operation.

In order to better determine the penetration point, with the cooperation of the positioning structure 6, the movable plate 7 is lifted and fixed, and the sliding range of the diagnostic and auscultatory probe 2 is set by the movable plate 7. During the sliding process of the slide buckle 4 along the slide rail 5, the diagnostic and auscultatory probe 2 can be slid, so as to move along the direction in which the auscultatory signal gradually increases, so as to finally find the penetration point.

[0025] The positioning structure 6 includes a sliding sleeve 61, which is vertically penetrated by a sliding hole. A rotating seat 65 is rotatably mounted on the bottom end of the sliding sleeve 61. A suction cup 66 is fixed to the bottom end of the rotating seat 65. A fixing plate 63 is fixed to the middle of the suction cup 66. A limiting ring 62 is sleeved on the top outer side of the sliding sleeve 61. The area of ​​the limiting ring 62 is larger than that of the fixing plate 63.

When the positioning structure 6 is fixed, the limiting ring 62 is pressed to press the sliding sleeve 61, so that the sliding sleeve 61 is fixed under the adsorption cooperation of the bottom suction cup 66, and the movable plate 7 is fixed.
