[0002] Building curtain walls refer to the non-load-bearing exterior wall cladding of a building, which usually consists of panels and a supporting structure behind them. During the construction of building curtain walls, it is usually necessary to test their flatness, which requires the use of flatness testing devices.
[0003] A search revealed that the announcement number is CN221077536U, and the name is "A Building Curtain Wall Construction Flatness Testing Device," which includes a main ruler. Research and analysis revealed that although it has the advantage of not requiring splicing installation, thus facilitating data recording by surveyors and preventing interference with the flatness measurement results, it also has the following disadvantages to some extent.
[0004] For example, during the use of this device, it usually requires staff to hold and inspect it manually, and it can only inspect one line on the surface of the exterior wall. The inspection range is small, and staff need to hold and move it multiple times, which increases the workload of staff and is inconvenient for people to use. In order to solve the above technical problems, we have designed a building curtain wall construction flatness inspection device. Utility Model Content
[0005] The purpose of this utility model is to provide a flatness testing device for building curtain wall construction, which has the advantage of a wide testing range. It solves the problems that the device usually requires workers to hold it by hand during use, and can only test one line on the exterior wall surface. The testing range is small, and workers need to hold and move it multiple times, which increases the workload of workers and makes it inconvenient for people to use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a building curtain wall construction flatness detection device, comprising a positioning shell, an installation shell welded to the front side of the positioning shell, an electric telescopic rod bolted to the surface of the installation shell, a telescopic suction cup bonded to the rear side of the positioning shell, a connecting plate bonded to the front side of the telescopic suction cup, the rear side of the electric telescopic rod bolted to the connecting plate, a fixing plate bolted to the front side of the installation shell, a motor bolted to the rear side of the fixing plate, an installation assembly mounted on the drive shaft of the motor, a threaded block mounted on the surface of the installation assembly, a buzzer bolted to the front side of the threaded block, a positioning frame welded to the rear side of the threaded block, a first release switch mounted on the surface of the positioning frame, a second release switch mounted on the rear side of the threaded block, a movable rod extending through the rear side of the positioning frame, a spring sleeved on the surface of the movable rod, and a roller bolted to the rear side of the movable rod.
[0007] Preferably, the mounting assembly includes a rotating block, the drive shaft of the motor is connected to the rotating block by bolts, a mounting bracket is welded to the right side of the rotating block, a motor is connected to the right side of the mounting bracket by bolts, the drive shaft of the motor is connected to a lead screw by bolts, and the surface of the lead screw is threadedly connected to the threaded block.
[0008] Preferably, the inner cavity of the mounting bracket is bolted to a guide rod, and the surface of the guide rod is slidably connected to the threaded block.
[0009] Preferably, a support ring plate is welded to the front side of the fixed plate, and the rear side of the rotating block is slidably connected to the support ring plate.

[0012] Preferably, the front side of the spring is welded to the positioning frame, and the rear side of the spring is welded to the roller.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a telescopic suction cup to adhere to the surface of the curtain wall. Then, the drive shaft of the motor drives the rotating block, mounting bracket, lead screw and threaded block to rotate. During the rotation of the threaded block, the roller will roll on the surface of the curtain wall. If the roller encounters a protrusion on the surface of the curtain wall, the roller will drive the movable rod to move back and forth. The movable rod will press the second release switch to start the buzzer. The buzzer will sound an alarm and at the same time stop the roller at the protrusion position. The staff can mark the protrusion position.
[0015] 2. When encountering a depression on the curtain wall surface, this utility model uses a spring to provide elastic force to the roller, which in turn drives the movable rod to move back and forth. The movable rod presses the first release switch, which activates the buzzer, causing it to sound as a warning. Simultaneously, the roller stops at the raised position, allowing workers to mark it for subsequent repairs. After testing at the same loop position, a motor drives a lead screw to rotate, which in turn drives the threaded block, positioning frame, movable rod, and roller to move laterally, adjusting the roller's detection position. The above operation can then be repeated to test different positions on the curtain wall. Attached Figure Description

[0024] Please see Figure 1 A support ring plate is welded to the front side of the fixed plate 6. By setting the support ring plate, the rotating block 8 can be supported and positioned, and the rotating block 8 can rotate stably. The rear side of the rotating block 8 is slidably connected to the support ring plate.
[0025] Please see Figure 1 and Figure 4 The rear side of the second release switch 16 contacts the movable rod 17, and the front side of the first release switch 15 contacts the movable rod 17. By setting the first release switch 15 and the second release switch 16, it is convenient to start the buzzer 13 and to trigger an alarm when an abnormality is detected.
[0026] Please see Figure 1 and Figure 4 The buzzer 13 is electrically connected to the first release switch 15 and the second release switch 16 respectively.
