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.
[0020] Please see Figure 1-4This utility model provides a technical solution: a waterproof testing mechanism for bicycle lights; including a test water tank 1, with a rotating fixing mechanism inside the test water tank 1, and a drive motor 2 fixed on the outside of the test water tank 1. A reducer 3 is connected to the output end of the drive motor 2, and the output end of the reducer 3 is matched and connected to the rotating fixing mechanism. The reducer 3 drives the rotating fixing mechanism to rotate stably and uniformly, fixing the bicycle light on the rotating fixing mechanism. Water spraying mechanisms are provided on both sides of the upper end of the test water tank 1, corresponding to the bicycle light fixed on the rotating fixing mechanism. When the rotating fixing mechanism rotates upward, water is sprayed through the water spraying mechanisms for testing, and then the rotation... The fixing mechanism rotates downwards into the test water tank 1. A test water level line 7 is set inside the test water tank 1. Water is poured into the test water tank 1 up to the test water level line 7. At this time, the headlight rotates downwards to immerse the headlight in water for another test. In this way, two waterproof tests are performed on the headlight in the test water tank 1: spray test and immersion test. A high-pressure pump 9 is set inside the lower end of the test water tank 1. The output end of the high-pressure pump 9 is connected to the water spraying mechanism. A connection port 8 is opened inside the test water tank 1. The connection port 8 is connected to the injection end of the high-pressure pump 9. The high-pressure pump 9 enables the internal water to be circulated and reused, saving water.
[0021] The rotating fixing mechanism includes a rotating rod 4, which is rotatably set inside the test water tank 1. One end of the rotating rod 4 is fixedly connected to the output end of the reducer 3. A support rod 5 is fixed on the side wall of the rotating rod 4. A fixing rod 6 is fixed to the end of multiple support rods 5. The vehicle lights are clipped onto the fixing rod 6. Multiple vehicle lights can be fixed on the fixing rod 6 at one time, which can increase the number of tests and efficiency.
[0022] The water spraying mechanism includes a main pipe 10, which is fixedly connected to the output end of a high-pressure pump 9. A branch pipe 11 is fixed at the upper end of the main pipe 10. Multiple output ends are provided on the side of the branch pipe 11. A nozzle 13 is fixed on each output end of the branch pipe 11. The nozzle 13 is located inside the test water tank 1 and is positioned at the highest point of the rotation of the fixed rod 6. Thus, when the high-pressure pump 9 pumps water from the main pipe 10 into the branch pipe 11 and then sprays it out from the nozzle 13, the sprayed water is continuously set to test the passing vehicle lights. A valve 12 is fixed on the corresponding branch pipe 11, and the valve 12 is positioned corresponding to the nozzle 13. The valve 12 is opened according to the number of vehicle lights being tested.
[0023] Protective plates 14 are fixed on both sides of the lower end of the test water tank 1. Heat dissipation holes 15 are provided on the protective plates 14. The high-pressure pump 9 at the lower end of the test water tank 1 can maintain its operating efficiency and improve internal heat dissipation through the heat dissipation holes 15.
[0024] The nozzle 13 has a flat outlet, and the outlet width of the nozzle 13 is equal to the distance between the two support rods 5, which allows for a wider range of testing of the vehicle lights.
