[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a human presence detector technical solution: including a detector body 1, a rotating block 2 and a flipping block 9. The rotating block 2 is fixedly installed at the bottom of the detector body 1. The bottom of the rotating block 2 is movably connected to a fixed block 3 through a first rotating shaft 5. The bottom of the rotating block 2 has a first arc-shaped groove 4 around the first rotating shaft 5. The top of the fixed block 3 has a first contraction groove 7 around the first rotating shaft 5. A first arc-shaped protrusion 6 is slidably arranged inside the first contraction groove 7. The first arc-shaped protrusion 6 extends into the interior of the first arc-shaped groove 4. A first resistance spring 8 is also arranged inside the first contraction groove 7. The two ends of the first resistance spring 8 are fixedly connected to the inner wall of the first contraction groove 7 and one end of the first arc-shaped protrusion 6, respectively.

[0017] Specifically, a flipping block 9 is fixedly installed at the bottom of the fixed block 3. A movable seat 10 is movably connected to the outer periphery of the bottom end of the flipping block 9 through a second rotating shaft 11. A second shrinkage groove 14 is provided on both sides of the inner wall of the movable seat 10 around the second rotating shaft 11. A second arc-shaped protrusion 15 is slidably provided inside the second shrinkage groove 14. A second arc-shaped groove 13 is provided on both sides of the bottom end of the flipping block 9 around the second rotating shaft 11. The second arc-shaped protrusion 15 extends into the interior of the second arc-shaped groove 13.

[0018] Specifically, the inner walls of the first shrinkage groove 7 and the second shrinkage groove 14 are provided with limiting grooves 17 on both sides, and the outer ends of the first arc-shaped protrusion 6 and the second arc-shaped protrusion 15 are provided with limiting blocks 18 on both sides. The limiting blocks 18 extend into the interior of the limiting groove 17 and slide in connection with its inner wall.

[0019] Specifically, a second resistance spring 16 is provided inside the second contraction groove 14, and the two ends of the second resistance spring 16 are fixedly connected to the inner wall of the second contraction groove 14 and one end of the second arc-shaped protrusion 15, respectively.

[0020] Specifically, a base 12 is fixedly installed at the bottom of the movable seat 10. The base 12 has a conical structure, and the movable seat 10 is installed on the top of the base 12.

[0021] Specifically, a suction cup 19 is provided on the bottom inner side of the base 12, and the suction cup 19 is fixedly embedded in the bottom inner side of the base 12.

[0022] In this embodiment, during use, the device is stably adsorbed onto a smooth surface at a suitable position by the suction cup 19 at the bottom of the base 12 to ensure the stability of the device. Then, the detector body 1 can be held and rotated as needed, causing the detector body 1 to drive the rotating block 2 to rotate. Although the first arc-shaped protrusion 6 extends into the interior of the first arc-shaped groove 4 under the action of the first resistance spring 8, generating a certain resistance, it does not affect the rotation of the rotating block 2. After rotating to a suitable angle, the resistance generated by the first arc-shaped protrusion 6 extending into the interior of the first arc-shaped groove 4 plays a certain positioning role, preventing rotation and ensuring the stability after adjustment. In addition, it can also drive the flipping block 9 to flip according to the required detection angle. The second arc-shaped protrusion 15 extends into the interior of the second arc-shaped groove 13 under the action of the second resistance spring 16, forming resistance on it. This creates a certain damping effect on the flipping block 9 after flipping, preventing the flipping block 9 from falling or resetting due to gravity, and ensuring the stability after adjustment.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
