Description

Technical Field

[0001] The utility model relates to the technical field of infrared sensor installation, and more specifically, to a leveling mechanism for an infrared sensor. Background Art

[0002] An infrared sensor is an intelligent device developed based on the principle of infrared reflection. During the installation process of an infrared sensor, an adjustment mechanism is required to adjust the sensing direction and tilt angle of the infrared sensor. However, for the commonly used infrared sensor adjustment mechanism, although it can adjust the sensing direction and tilt angle position, it cannot accurately adjust the direction angle and tilt angle, and needs to be adjusted repeatedly, which brings inconvenience to users.

[0003] For example, an infrared sensor with an angle adjustment bracket disclosed in the patent publication number CN217843347U includes an infrared sensor body. One side of the mounting block is provided with an adjustment component two for adjusting the up and down angle of the infrared sensor body. Both of the sliding blocks are movably sleeved outside the slide rail, and an adjustment component one for adjusting the left and right angle of the infrared sensor body is provided inside the slide rail.

[0004] As can be seen from the above disclosed solution, the sensing direction of the infrared sensor body is adjusted by the adjustment component one, and the tilt angle of the infrared sensor body is adjusted by the adjustment component two. However, during the adjustment of the left and right angles and up and down angles of the infrared sensor, it cannot be accurately adjusted to the required angle position and needs to be debugged repeatedly, which brings great inconvenience to users.

The side of the limiting plate 21 is provided with an indicating block 22, and the shape of the indicating block 22 is triangular. Both ends of the adjusting shaft 2 are respectively connected with a fastening sleeve 25 and a positioning sleeve 27 by threads. One end of the limiting block 24 is clamped with a mounting block 3. The surface of the mounting block 3 is provided with a mounting groove 31. The side of the mounting groove 31 is provided with symmetric shaft holes, and the inner wall of the shaft hole is movably sleeved with a rotating shaft 41.
