Infrared position indicator

The invention discloses an infrared position indicator, which includes an infrared position indicator body, an inspection port installed on the lower part of the infrared position indicator body and ashort pipe installed on the lower part of the inspection port. The infrared position indicator body is provided with one or more vertical infrared rays and horizontal infrared rays, and the outer diameters of short pipes are matched with the inner diameters of drainage embedded parts. The infrared position indicator body is used for being connected with the inspection port, then the short pipes are connected with the drainage embedded parts, and the center position of the drainage embedded part of an upper layer floor can be positioned reversely and vertically. The drainage embedded part of the layer is used as a positioning reference, and the positioning accuracy error can be improved by 1-2 mm. 本发明种红外线定位仪，包括红外线定位仪、安装在红外线定位仪下部的检查口以及安装在检查口下部的短管，红外线定位仪至少具有条垂直红外线和水平红外线，短管外径与排水预埋件内径相适配。利用红外线定位仪及检查口连接，然后通过短管与排水预埋件连接，
