Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] As Figures 1-5 shown, a box-type rain test chamber for automobile lamp production includes a box body 1. A test chamber 2 is inwardly opened on the front side of the box body 1. A first chamber door 3 is rotatably installed on the outside of the test chamber 2. On the inner upper surface of the test chamber 2, three arc-shaped water pipes 4 are fixedly connected and arrayed. A number of shower nozzles 5 are arrayed and fixedly installed on the lower surface of the arc-shaped water pipe 4. A connecting water pipe 6 extends outward from the side surface of the test chamber 2 and is fixedly connected. A long strip nozzle 7 is fixedly connected to the side of the connecting water pipe 6 close to the middle of the test chamber 2. A first fixing cylinder 8 is fixedly connected to the lower surface of the test chamber 2. A first motor 9 is fixedly installed inside the first fixing cylinder 8 on the lower surface of the test chamber 2. The output end of the first motor 9 is fixedly connected to a rotating rod 10. The rotating rod 10 extends upward through the top of the first fixing cylinder 8 and is fixedly connected to a fixing block 12. A rotating bar 13 is rotatably connected inside the fixing block 12. The rotating bar 13 is fixedly connected to the center of the lower surface of a placing plate 11. A second motor 15 is fixedly connected to one side surface of the fixing block 12. A second fixing cylinder 14 is sleeved and fixedly connected to the side surface of the fixing block 12 on the outer surface of the second motor 15. By fixing the lamp on the placing plate 11 and starting the first motor 9 and the second motor 15, at this time, the placing plate 11 and the lamp are rotated to a suitable inclination angle with the rotating bar 13 as the center, and the lamp is driven to rotate by the rotating rod 10. At this time, then open the shower nozzles 5 at the top for a rain test, and at the same time intermittently inject water into the connecting water pipe 6 so that the water curtain is sprayed from the long strip nozzle 7 onto the lamp to simulate the situation during driving, so as to test whether the gap connection is firm enough when the produced lamp is hit by such a large amount and large-impact water curtain, thereby improving the detection effect of the device on the lamp.

[0022] As Figure 2As shown, in some embodiments, the extended part of the connecting water pipe 6 slopes downward, and the long strip nozzle 7 is fixedly connected to the outer surface of the inclined part of the connecting water pipe 6. Specifically, by setting it inclined, when the lamp rotates, the entire side surface can be impacted by the water curtain, avoiding the water curtain always impacting a fixed-height circular range and affecting the test results.

[0023] As Figure 4 shown, in some embodiments, one end of a U-shaped connecting block 16 is fixedly connected to the outer surface of the placement plate 11. The other end of the U-shaped connecting block 16 extends above the placement plate 11 and is penetrated by a threaded rod 17. The threaded rod 17 is threadedly connected to the U-shaped connecting block 16. One end of the threaded rod 17 close to the placement plate 11 is rotatably connected to a clamping plate 18. Specifically, after placing the lamp on the placement plate 11, rotate the threaded rod 17 to drive the clamping plate 18 to press down to clamp and fix the lamp, so as to uniformly fix lamps of various shapes. When the placement plate 11 is inclined, the U-shaped connecting block 16 should be located below, so as to support the bottom of the lamp.

[0024] As Figure 4 shown, in some embodiments, anti-slip pads 19 are fixedly connected to the upper surface of the placement plate 11 and the lower surface of the clamping plate 18. Specifically, by installing the anti-slip pads 19, after the lamp, the placement plate 11, and the clamping plate 18 are wetted by water, the lamp will not be easily impacted and fallen off by the water curtain due to the easy slipping between their surfaces.

[0025] As Figure 1 、 5 shown, in some embodiments, a water tank chamber 20 is opened below the front side of the box body 1 in the test chamber 2. A chamber door two 21 is rotatably installed on the outside of the water tank chamber 20. A water storage tank 22 is placed inside the water tank chamber 20. A drain pipe 23 penetrates and is fixedly connected to the lower surface of the test chamber 2. The drain pipe 23 extends downward to be close to the bottom of the water storage tank 22. Specifically, through the drain pipe 23, the water sprayed inside the test chamber 2 will flow into the placed water storage tank 22, which is convenient for storage and reuse. The deeper extension of the drain pipe 23 can prevent water from splashing outside the water storage tank 22. In actual use, the drain pipe 23 can be set as a flexible pipe, avoiding being blocked by the drain pipe 23 when the water storage tank 22 is pulled, affecting the cleaning of its interior, and also facilitating taking out the bottom end of the drain pipe 23 to drain the circulating water multiple times to replace the test water.

[0026] As Figure 5 shown, in some embodiments, a water pump 24 is placed inside the water storage tank 22. The water outlet of the water pump 24 is fixedly connected to a water suction pipe 25. The water suction pipe 25 extends upward and is connected to the water supply system inside the box body 1. Specifically, by turning on the water pump 24, the water in the water storage tank 22 is pumped back into the water supply system inside the box body 1, thereby achieving the purpose of recycling water in the device and saving water better.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
