A drainage ring 5 is fixedly installed on the top of the water storage bucket 4. The drainage ring 5 is designed with a large upper opening and a small lower opening,呈喇叭形状, so that the sprayed water can be smoothly led into the water storage bucket 4. An installation platform 6 is arranged above the drainage ring 5. A U-shaped frame 7 is fixedly installed at the bottom of the installation platform 6. A clamping mechanism is arranged on the U-shaped frame 7 to clamp the LED lamp. A U-shaped pipe 11 is fixedly installed on the top of the sealing cover 3, and a ring pipe 12 is fixedly installed at the bottom of the U-shaped pipe 11. Six nozzles 13 distributed in a circular array are fixedly installed at the bottom of the ring pipe 12. In this way, the LED lamp can be waterproof tested from multiple directions. A lifting rod 21 is slidably installed on the test bench 1. Its top penetrates through the water storage bucket 4 and is slidably and sealingly connected to the bottom of the water storage bucket 4. The top of the lifting rod 21 is fixedly connected to the U-shaped frame 7. A lifting mechanism is arranged below the test bench 1 to lift and lower the lifting rod 21, so that the installed LED lamp can be brought down into the water storage bucket 4, thereby enabling a water pressure waterproof test and improving the diversity of waterproof tests.

[0026] The clamping mechanism mentioned above includes a bidirectional screw 8. The bidirectional screw 8 is rotatably installed on both sides of the U-shaped frame 7. Two linkage plates 9 are threadedly installed on the bidirectional screw 8. Clamping strips 10 are fixedly installed on one side of the two linkage plates 9 close to each other. In order to ensure that the linkage plates 9 can only move linearly horizontally, two limiting rods one are fixedly installed on the outer walls of both sides of the U-shaped frame 7. The corresponding two limiting rods one penetrate through the corresponding linkage plates 9 and are slidably connected to them.

[0027] The lifting mechanism mentioned above includes two connecting pieces. Both connecting pieces are fixedly installed on the same support plate 2. The same U-shaped frame 18 is fixedly installed on the two connecting pieces. A lifting screw 19 is rotatably installed inside the U-shaped frame 18. The bottom end of the lifting screw 19 extends below the U-shaped frame 18. A lifting platform 20 is threadedly installed on the lifting screw 19. The top of the lifting platform 20 is fixedly connected to the lifting rod 21. In order to ensure that the lifting platform 20 can only move linearly up and down, two limiting rods two are fixed inside the U-shaped frame 18. Both limiting rods two penetrate through the lifting platform 20 and are slidably connected to it.

[0028] In this method, in order to extract water for waterproof testing of the LED lamp, a water pump 14 is fixedly installed on the outer wall of one side of the sealing cover 3, and a water outlet pipe 15 is fixedly installed on the water outlet thereof. The water outlet pipe 15 is connected with the shaped pipe 11 through a water pipe 16, and a water valve 1 is provided on the water pipe 16. One end of a water pipe 2 17 is fixedly installed on the water outlet pipe 15, and the other end of the water pipe 2 17 extends into the water storage barrel 4, and a water valve 2 is provided on the water pipe 2 17. The water pipe 2 17 passes through one side of the sealing cover 3.

[0029] In this method, two connecting pieces are arranged vertically one above the other, and a rotating shaft is rotatably installed on the connecting piece located at the bottom. Synchronous wheels are fixedly sleeved on the rotating shaft and the lifting screw 19. The two synchronous wheels are sleeved with the same synchronous belt. A motor is fixedly installed on the connecting piece located at the bottom, and its output shaft is fixedly connected to the top end of the rotating shaft.

[0030] The working principle of the LED lamp waterproof test equipment provided by the utility model is as follows:

[0031] The water inlet of the water pump 14 is connected to the external water tank through an external pipe, and in the initial state, the water valve 1 and the water valve 2 are both closed;

[0032] When conducting a waterproof test on the LED lamp, first open the sealing door in the installation opening, then place the LED lamp on the installation table 6, then rotate the bidirectional screw 8, the two linkage plates 9 move in a direction close to each other, and finally clamp the LED lamp through the two clamping strips 10. After clamping, first open the water valve 1, randomly start the water pump 14 to start pumping water, and the pumped water enters the ring pipe 12 through the water guide pipe 16 and the shaped pipe 11 in turn, and finally sprays out through the nozzle 13 and sprays on the LED lamp, thereby simulating rainy weather to conduct a waterproof test on the LED lamp, and the water sprayed during the test directly falls into the water storage bucket 4 for storage;

[0033] After the above test method is completed, if there is no problem with the LED lamp, continue to perform the immersion test. During the test, first close the water valve 1, then open the water valve 2, continue to start the water pump 14, and the pumped water will enter the water storage barrel 4 through the water pipe 2 17. After a certain amount of water is injected, turn off the water pump 14, and then start the motor in the forward direction. Its output shaft drives the rotating shaft to rotate. At this time, through the transmission between the synchronous wheel and the synchronous belt, the lifting screw 19 can be driven to rotate. Therefore, under the threaded cooperation between the lifting screw 19 and the lifting platform 20, the lifting rod 21 brings the shaped frame 7 down, and the mounting platform 6 and the installed LED lamp are lowered accordingly, until the LED is immersed in the water to the specified height position, and then the motor is turned off. At this time, the water pressure test of the LED lamp can be formed;

[0034] After all tests are completed, start the motor in reverse to bring the LED lamp back to its original height, then take it out and replace it with the next LED lamp to be tested.

[0035] Compared with the related art, the LED lamp waterproof testing equipment provided by the utility model has the following beneficial effects:

[0036] The utility model provides a waterproof testing device for LED lamps. By means of the arranged convex tube 11, the ring tube 12 and the nozzle 13, a waterproof test simulating rainy days can be performed on the LED lamps. Moreover, after the waterproof test is completed, the LED lamps can be brought into a water storage barrel 4 for a water pressure waterproof test by means of the threaded cooperation of the lifting screw 19 and the lifting platform 20. Thus, two testing methods can be realized, and the two testing processes can be performed in sequence, which greatly improves the comprehensiveness of the waterproof performance test of the LED lamps.
