The pushing assembly 5 includes an electric telescopic rod 51 connected to the flip plate 49; the other end of the electric telescopic rod 51 is rotatably connected to a hinge ball 52; the other end of the hinge ball 52 is rotatably connected to a bonding plate 53; a mounting groove is provided on the bonding plate 53; a sliding rod 54 is connected in the mounting groove; and a camera probe 57 is slidably connected to the sliding rod 54.

[0025] By turning the handle 1 25, the gear 24 is driven to rotate, thereby driving the slide bar 23 meshing with the gear 24 to rise and fall, and the camera probe 57 can be adjusted to a suitable height. The lifting of the slide bar 23 can drive the telescopic rod 41 connected thereto to extend and retract, thereby keeping the bevel gear 3 46 and the bevel gear 4 47 always meshed. By turning the handle 2 44, the bevel gear 2 43 is driven to rotate, thereby driving the telescopic rod 41, the bevel gear 1 42 and the bevel gear 3 46 to rotate, and then driving the bevel gear 4 47 and the rotating column 48 to rotate, so that the flip plate 49 is flipped with the rotation of the rotating column 48, and the camera probe 57 can be adjusted to a suitable angle. The building cracks of any height and any angle can be detected, which improves the convenience of the device, and also avoids the construction personnel from climbing up to detect the high wall such as the ceiling, thereby reducing the safety risk. By starting the electric telescopic rod 51, the bonding plate 53 is bonded to the wall surface, so that the camera probe 57 is flush with the crack, which increases the accuracy of the detection result. Example

[0026] like Figure 1-5 As shown, the engineering air tightness detection device proposed by the utility model, compared with the first embodiment, this embodiment also includes: the sleeve 21 is connected with the installation box 3; the through hole 22 is connected with the installation box 3; the gear 24 is arranged inside the installation box 3; the handle 1 25 passes through the installation box 3.

The lifting of the slide bar 23 can drive the telescopic rod 41 connected thereto to extend and retract, thereby keeping the bevel gear 3 46 and the bevel gear 4 47 always meshed. When the camera probe 57 is lifted to a suitable height, adjust the flip assembly 4 according to the angle of the crack, that is, turn the handle 2 44, the handle 2 44 rotates to drive the bevel gear 2 43 to rotate, thereby driving the telescopic rod 41, the bevel gear 1 42 and the bevel gear 3 46 to rotate, and then driving the bevel gear 4 47 and the rotating column 48 to rotate, so that the flip plate 49 flips with the rotation of the rotating column 48.

Then, the motor 56 is started to make the camera probe 57 slide along the sliding rod 54 and the threaded rod 55 and align with the crack. Finally, the detection result can be recorded according to the value detected by the camera probe 57.

[0028] By setting the lifting component 2 and the flip component 4, building cracks at any height and angle can be detected, which improves the convenience of using the device and avoids the construction workers from climbing up to detect high walls such as ceilings, thereby reducing safety risks. By setting the pushing component 5, the camera probe 57 can be flush with the crack, thereby increasing the accuracy of the detection result.
