[0002] An infrared detector is a device used to detect and measure infrared radiation. Infrared radiation is part of the electromagnetic spectrum with wavelengths typically ranging from 0.75 microns to 1000 microns, between visible light and microwaves.

[0003] The infrared detector is usually connected by arranging four-core wires at the place of use for installation with the mainboard, including two power lines and two signal lines. In order to make the infrared detector look aesthetically pleasing, the length of the four-core wire is usually set to be consistent with the installation and connection position of the infrared detector, and then a ladder is used to connect the line to the mainboard. Due to the high installation height and the need to use tools to disassemble the detector and connect the lines, all subsequent maintenance and replacement operations need to be performed at high altitudes, which is cumbersome for operators and poses certain safety hazards.

[0004] Therefore, it is necessary to design a wall-mounted infrared detector to solve the above problems. Utility Model Content

When wiring, a line length consistent with the installation height can be reserved. First, fix the adjustable mounting part 2 at the installation position, pass the connecting end of the four-core wire through the threading hole 3, pass the remaining end of the line through the wire pressing mechanism, and fix the wire end. After the infrared detector body 1 is connected to the four-core wire, hook the two hook ropes 6 with the second connecting plate 5, then turn on the micro motor 7, and use the rotating shaft to drive the winding wheel 8 to rotate, so that the two hook ropes 6 can be wound around the inside of the two second winding grooves 10. At the same time, the reserved four-core wire will be wound around the first winding groove 9 until the bottom of the first connecting plate 4 fits with the top of the hook rope 6, thereby completing the installation of the infrared detector body 1. After installation, the detection angle of the infrared detector body 1 is adjusted by the adjustable mounting part 2.

[0022] It should be noted that the wire pressing mechanism mentioned in the above description includes a fixed block 15. After the end of the four-core wire passes through the through-hole, an installation length is reserved. Then, the rotation of the rotating block 11 drives the threaded rod 12 to rotate. Since the pressing block 13 is slidably inserted into the sliding groove of the fixed block 15, the pressing block 13 can be lowered to fix the four-core line, thereby ensuring the stability of the line when the infrared detector body 1 is raised or lowered, and it is also convenient to wind the line around the first winding groove 9.

[0023] In order to better fix the four-core wire passing through the through hole and prevent the four-core wire from being damaged, the pressing block 13 is a semicircular block, and the bottom of the pressing block 13 is a semicircular arc surface.

[0024] Furthermore, in order to facilitate the laying of the line and ensure the stability of the winding connection between the line and the first winding groove 9, the threading hole 3 and the through hole are located at the same horizontal plane, and the size of the threading hole 3 matches the size of the connecting wire of the infrared detector body 1.

[0025] In order to improve the stability of the infrared detector body 1 during lifting and to ensure the stability of the infrared detector body 1 after installation, the two second winding grooves 10 are respectively located on both sides of the first winding groove 9, and the first connecting plate 4 is U-shaped, and the bottom of the first connecting plate 4 is in contact with the top of the second connecting plate 5.
