[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1-Figure 4 ,in, Figure 1 A schematic diagram of the structure of an infrared sensor that is easy to install and position provided by the utility model; Figure 2 for Figure 1 A cutaway view of an infrared sensor is shown; Figure 3 for Figure 2 A schematic diagram of the structure when the rotating device and the positioning device are combined; Figure 4 for Figure 3 An exploded view of the rotating device and the positioning device is shown.

[0023] In the specific implementation process, Figure 1-Figure 4 As shown, an infrared sensor that is easy to install and position includes a base 1, a rotating device 15 and a positioning device 16. An accommodating space is opened inside the base 1, a mounting groove 11 is opened at the center of the base 1, an infrared sensor housing 2 is placed inside the mounting groove 11, the rotating device 15 is arranged in the accommodating space, and the positioning device 16 is fixedly arranged at the bottom end of the infrared sensor housing 2;

[0024] A groove 6 is provided at the bottom of the accommodating space, and the rotating device 15 includes a rotating rod 3. The bottom end of the rotating rod 3 is fixedly connected to a limiting disk 5, and the limiting disk 5 is movably arranged in the groove 6. A plurality of limiting grooves 7 are provided on the side wall of the limiting disk 5, and an insertion hole 17 is provided above one end of the limiting groove 7. Only when the limiting disk 5 is rotated to the position of the insertion hole 17, the infrared sensor housing 2 can be taken out. An auxiliary block 4 is movably provided on the outer wall of the rotating rod 3, and the rotating rod 3 can be rotated in the auxiliary block 4. One end of the rotating rod 3 and the top end of the auxiliary block 4 extend out of the top surface of the base 1, and the auxiliary block 4 is fixedly connected to the top of the infrared sensor housing 2, so that the operator can rotate the rotating rod 3. The positioning device 16 includes a positioning rod 9 and a positioning column 8. The positioning column 8 is hollow, and a spring 12 is movably sleeved on the positioning rod 9, and the positioning rod 9 extends out of the infrared sensor housing 2.

[0025] The mounting groove 11 is adapted to the bottom of the infrared sensor housing 2 and the positioning rod 9 extending out from one side of the infrared sensor housing 2. When the infrared sensor housing 2 is aligned with the mounting groove 11 and the infrared sensor housing 2 is moved downward, the positioning rod 9 is squeezed by the inner wall of the mounting groove 11, and the spring 12 is in a compressed state, which facilitates the positioning rod 9 to extend into the limiting groove 7.

[0026] A limiting ball 13 is fixedly installed at one end of the positioning rod 9. The limiting ball 13 is adapted to the limiting groove 7 and can extend into the limiting groove 7. A ring 10 is fixedly installed on the positioning rod 9. The ring 10 is inside the positioning column 8 and is located on one side of the positioning column 8. The ring 10 is used to resist against the end of one side of the positioning column 8 and the spring 12.

[0027] The limiting ball 13 is a hemispherical body. Since the outer surface of the hemispherical body is arc-shaped, there will be no jamming when taking the infrared sensor housing.

[0028] One end of the spring 12 abuts against one end of the positioning column 8, and the other end of the spring 12 abuts against the ring 10. When the limiting ball 13 is squeezed by the inner wall of the mounting groove 11, the limiting ball 13 drives the positioning rod 9 to move in the positioning column 8, and the ring 10 squeezes the spring 12, driving the spring 12 to contract, so that the limiting ball 13 can move into or out of the limiting groove 7.

[0029] The groove 6 is communicated with the mounting groove 11 , so that the limiting ball 13 can extend into the limiting groove 7 .

[0030] A protective cover 14 is provided on the portion of the positioning rod 9 extending out of the infrared sensor housing 2 to prevent the positioning rod 9 from being accidentally touched when the infrared sensor is not in use, causing the limit plate 5 to rotate and the infrared sensor housing 2 to lose its limit.

[0031] The working principle provided by the utility model is as follows: when installing the infrared sensor, align the infrared sensor housing 2 with the mounting groove 11, and move the infrared sensor housing 2 downward. At this time, the limiting ball 13 is squeezed by the inner wall of the mounting groove 11, driving the positioning rod 9 to move in the positioning column 8, and the ring 10 squeezes the spring 12, driving the spring 12 to contract. When the infrared sensor housing 2 reaches the bottom of the mounting groove 11, the limiting ball 13 also reaches the connection between the mounting groove 11 and the groove 6, remove the protective cover 14, rotate the rotating rod 3, and the rotating rod 3 drives the limiting ball 13 to move in the positioning column 8. The positioning disk 5 rotates in the groove 6. When the limiting groove 7 is rotated to the position where the mounting groove 11 and the groove 6 are connected, the limiting ball 13 is no longer squeezed by the inner wall of the mounting groove 11, and the spring 12 is no longer compressed. The limiting ball 13 extends into the limiting groove 7. The rotating rod 3 is rotated again to make the positioning rod 9 move away from the end where the through hole 17 is located until the positioning rod 9 reaches the other end of the limiting groove 7. At this time, the infrared sensor housing 2 is limited to the base 1. Only when the limiting disk 5 is rotated to the position of the through hole 17 can the infrared sensor housing 2 be taken out.
