The inner wall of the slot 103 is movably connected with an insert block 104, and the top of the insert block 104 passes through the top of the mounting block 101.

[0024] As a technical optimization solution of the utility model, by setting up the protective component 10, the protective cover 102 can be effectively placed into the interior of the mounting block 101, and the plug block 104 is inserted into the inner wall of the slot 103, so that the protective cover 102 can be positioned. The protective cover 102 can protect the infrared sensor 8 to prevent dust from affecting the service life of the infrared sensor 8.

[0025] refer to Figure 1 and Figure 2 The adjustment component 11 includes an electric push rod 111, which is fixedly connected to the top of the inner wall of the slide groove 6. A U-shaped block 112 is fixedly installed at the output end of the electric push rod 111, and the bottom of the U-shaped block 112 is fixedly connected to the top of the mounting frame 7.

[0026] As a technical optimization solution of the utility model, by setting the adjustment component 11, the electric push rod 111 can effectively drive the U-shaped block 112 to move, so that the U-shaped block 112 can drive the mounting frame 7 to adjust up and down, thereby facilitating the user to adjust the infrared sensor 8 to the desired height, so as to facilitate the user to adjust the detection range of the infrared sensor 8.

By using the T-shaped seat 17 in conjunction with the base 1, the stability of the rectangular tube 2 when placed can be improved, preventing the rectangular tube 2 and the warning cloth strip 5 from shaking.

[0035] The working principle and use process of the utility model are as follows: when in use, the user first puts the mounting bracket 7 into the inside of the slide slot 6, fixes the infrared sensor 8 through the mounting bracket 7, detects pedestrians through the infrared sensor 8, and when it is detected that the pedestrian is approaching the warning light bar 9, the infrared sensor 8 transmits a signal to light up the warning light bar 9, and the warning light bar 9 can warn the pedestrian, and the infrared sensor 8 transmits a signal and starts the buzzer 15, and the buzzer 15 can warn the surrounding pedestrians, thereby improving the safety of the warning device, so that the pedestrians who lower their heads to play with mobile phones or do not pay attention to the front can be warned, and the safety of the warning device is enhanced. To prevent the warning cloth strip 5 from causing pedestrians to trip, the user then places the protective cover 102 into the interior of the mounting block 101 and inserts the plug block 104 into the inner wall of the slot 103, thereby positioning the protective cover 102 so that the protective cover 102 can protect the infrared sensor 8 and prevent dust from affecting the service life of the infrared sensor 8. Then the electric push rod 111 drives the U-shaped block 112 to move, so that the U-shaped block 112 can drive the mounting frame 7 to adjust up and down, thereby facilitating the user to adjust the infrared sensor 8 to the desired height, so as to facilitate the user to adjust the detection range of the infrared sensor 8, thereby improving the flexibility of the infrared sensor 8.

[0036] To sum up: this kind of warning device installed in an elevator, by setting a mounting frame 7, an infrared sensor 8, a warning light bar 9 and a protective component 10, can effectively enable the infrared sensor 8 to detect pedestrians. When a pedestrian is detected approaching the warning light bar 9, the infrared sensor 8 transmits a signal to light up the warning light bar 9. The warning light bar 9 can warn the pedestrian, thereby improving the safety of the warning device and solving the problem that although the warning device can warn the surroundings, when the pedestrian is playing with the mobile phone with his head down or not paying attention to the front, the warning cloth strip will cause the pedestrian to trip, thereby causing injury to the pedestrian, which poses a certain risk.
