[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] like Figure 1As shown, a corrugated pipe positioning ruler comprises a main body 1, a sleeve 2 arranged on the main body 1 and raised and lowered on the main body 1, two support rods 3 are arranged side by side on the side of the sleeve 2, and a positioning mechanism for positioning the threaded pipe is provided on the upper end of the support rod 3. The length of the standard section of the corrugated pipe changes with the length of the beam, but the height of the corrugated pipe remains unchanged. According to the height value on the drawing, the position of the sleeve 2 is adjusted, and according to the position of the positioning steel bar, the accurate positioning of the standard section of the corrugated pipe can be ensured. It reduces the repeated work of workers' tape measurement and avoids inaccurate positioning caused by excessive flexibility of the tape measure. According to the traditional measurement method, it takes about 40 minutes for two workers to position the four corner corrugated pipes. Using this positioning ruler, one worker only needs 10 minutes to complete the positioning work. This positioning ruler greatly improves work efficiency, speeds up the progress of on-site construction, is simple to make, requires little investment, and is easy to operate.

[0020] The corrugated pipe is inserted between the two support rods and locked by a positioning machine to prevent the main body from falling, making construction easier.

[0021] like Figure 2 As shown, the main body 1 is provided with a long hole 4, and the side wall of the sleeve 2 passes through the long hole 4. The sleeve 2 can move up and down along the long hole 4, and the position of the sleeve can be fine-tuned according to the position of the bellows, which has a wide range of applications.

[0022] like Figure 2 As shown, the main body 1 is provided with a positioning screw 5 for positioning the sleeve 2.

[0023] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a through hole set in the support rod 3, a positioning head 6 is provided in the through hole, the front end of which is rotatably connected to the inner wall of the through hole, and the lower end of the positioning head 6 is provided with an inclined surface inclined downward from the outside to the inside. When the bellows enters between the upper and lower support rods 3, the positioning head 6 swings downward, and the bellows is locked by the positioning head 6, thereby fixing the body and facilitating the installation of the remaining bellows.

[0024] like Figure 2 As shown, a limit plate 7 is provided at one inner end of the upper end surface of the protected positioning head 6, through which the angle of the positioning head is limited, and the limit plate is used to facilitate lifting the positioning head 6 and removing the main body.

[0025] like Figure 2 As shown, a scale 8 is provided on the side of the body 1 .

[0026] like Figure 2 As shown, a handle 9 is provided on the body 1 .
