Description

Technical Field

[0001] This utility model relates to the field of infrared sensing lens technology, and in particular to a human body infrared sensing lens. Background Technology

[0002] Existing technology, such as Chinese utility model patent document, publication number CN213930843U, discloses an LED light with an infrared sensor control switch, including an upper shell and a lower shell, which are connected by screws, forming a placement cavity between the upper shell and the lower shell. A PCB circuit board is installed in the placement cavity, and an infrared sensor, a light sensor, and a transformer are set on the PCB circuit board. The upper end face of the upper shell has mounting holes corresponding to the positions of the infrared sensor and the light sensor, and an infrared lens is set in the mounting holes. The lower end face of the lower shell has a plug, which is electrically connected to the PCB circuit board. A lamp cover is inserted into the right end of the upper shell and the lower shell, and an LED light board is set inside the lamp cover, and the LED light board is electrically connected to the PCB circuit board.

[0003] Based on the above, in existing technologies, infrared sensors require the use of lenses. Current infrared lenses are generally installed within mounting holes in the housing using a snap-fit ​​method. While this snap-fit ​​method allows for tool-free assembly and is highly efficient, it presents a problem later on. If the lens is damaged due to impacts or other factors, the clips within the mounting holes are difficult to disengage. Often, the user needs to break the entire lens and then separate the clips, making disassembly very difficult and requiring further improvement. Utility Model Content

[0032] Please see Figure 1-11 This utility model provides a technical solution: a human infrared sensing lens, including a mounting housing 1 and a lens housing 2. The mounting housing 1 has a mounting groove 14. The lens housing 2 is movably inserted into the inner cavity of the mounting groove 14. The lens housing 2 and the mounting groove 14 are matched with each other. The bottom of the lens housing 2 has a groove 10. The top of the lens housing 2 is fixedly connected to two insert blocks 13. The top of the inner cavity of the mounting groove 14 has two insertion holes 12. The insert blocks 13 are movably inserted into the inner cavity of adjacent insertion holes 12. The two insert blocks 13 are symmetrically arranged about the central axis of the lens housing 2. The front side of the lens housing 2 near the bottom has a circular groove 3. The rear side of the inner cavity of the circular groove 3 has a through hole 11. The inner cavity of the through hole 11 is rotatably connected to a rotating rod 5.

[0033] A circular plate 4 is fixedly connected to the front end of the rotating rod 5. A cross groove is opened on the front side of the circular plate 4. The circular plate 4 is movably inserted into the inner cavity of the circular groove 3. A fixing frame 6 is fixedly connected to the rear side of the lens housing 2 near the bottom. The rear end of the rotating rod 5 is rotatably connected to the fixing frame 6. The cross-section of the fixing frame 6 is L-shaped. A torsion spring 7 and a movable plate 8 are provided on the inner side of the fixing frame 6. The rear end of the rotating rod 5 is fixedly inserted through the movable plate 8. The rear end of the rotating rod 5 is movably inserted through the torsion spring 7. The front end of the torsion spring 7 is fixedly connected to the movable plate 8. The rear end of the torsion spring 7 is fixedly connected to the inner side of the fixing frame 6. A baffle 9 is provided on the right side of the movable plate 8 near the bottom. The cross-section of the baffle 9 is L-shaped. The movable plate 8 is movably inserted into the inner side of the baffle 9. The baffle 9 is fixedly connected to the rear side of the mounting housing 1.

[0034] Working principle: This utility model discloses a human infrared sensing lens. During use, when it is necessary to disassemble the lens housing 2, the fingernail is inserted into the "+" groove on the front side of the circular plate 4. Then, the other hand holds the groove 10 and rotates the circular plate 4 with the fingernail. The circular plate 4 drives the rotating rod 5 and the movable plate 8 to rotate. At the same time, the torsion spring 7 is torsionally deformed, and the movable plate 8 rotates away from the baffle 9, flipping the movable plate 8 to a horizontal state, thereby releasing the fixation of the lens housing 2. Then, the finger holding the groove 10 is used to press the lens housing 2 forward. The lens housing 2 flips downward away from the mounting groove 14. Then, the force on the circular plate 4 is released, and the rotating rod 5 and the movable plate 8 are reset under the elastic action of the torsion spring 7. After that, the lens housing 2 is moved downward, and the lens housing 2 drives the insert block 13 to move downward away from the insertion hole 12, thereby removing the lens housing 2.

[0035] When installing the lens housing 2, first move the lens housing 2. The lens housing 2 drives the insert block 13 to be inserted into the inner cavity of the insertion hole 12. Insert the fingernail into the "+" groove on the front side of the circular plate 4. Then, hold the groove 10 with the other hand and rotate the circular plate 4 with the fingernail. The circular plate 4 drives the rotating rod 5 and the movable plate 8 to rotate. At the same time, the torsion spring 7 is torsionally deformed, flipping the movable plate 8 to a horizontal state. Then push the lens housing 2 to the rear. The lens housing 2 is inserted into the inner cavity of the mounting groove 14. Then release the force on the circular plate 4. The rotating rod 5 and the movable plate 8 are reset under the elastic action of the torsion spring 7. The movable plate 8 is then inserted into the inner side of the baffle 9, thereby fixing the lens housing 2.

[0036] When installing the lens housing 2, the device only requires positioning the lens housing 2 by first using the insertion block 13 and the insertion hole 12. Then, the circular plate 4 is rotated by the fingernail, and the lens housing 2 is pushed backward. The lens housing 2 is inserted into the inner cavity of the mounting groove 14. Then, the force on the circular plate 4 is released, and the rotating rod 5 and the movable plate 8 are reset under the elastic action of the torsion spring 7. The movable plate 8 is then inserted into the inner side of the baffle 9, thereby fixing the lens housing 2. That is, the lens housing 2 of this device can be installed and disassembled without the aid of tools, which makes the assembly efficiency high and the operation simple.
