Description

Technical Field

[0001] The utility model relates to the technical field of test boxes, in particular to a rain test box. Background Art

[0002] The rain test chamber is a device used to test the waterproof performance of electronic, mechanical, construction, automotive and other products. It simulates the impact and erosion of rain to evaluate the sealing and waterproof performance of the product.

[0003] For example, patent publication number CN218444302U discloses a rain test chamber with adjustable rain intensity, comprising a chamber body, a wind simulation assembly disposed on the left side of the chamber body, a placement plate secured between the left and right side walls of the chamber body, a test bench secured to the upper surface of the placement plate, and an adjustment mechanism disposed on the right side of the chamber body. While the adjustable rain test chamber achieves rotation of a rotating tube through the interaction of various structures in the adjustment mechanism, thereby enabling rainwater to be sprayed from different angles, and furthermore, utilizes a solenoid valve and a control valve to control the water flow rate and adjust the rain intensity, the device has some drawbacks. In actual use, the test bench cannot be adjusted in angle. When testing a test object, the test can only be performed when the test object is horizontally placed on the test bench, resulting in a relatively concentrated rainwater fall on the upper surface of the test object. This makes it impossible to test the rain intensity at different positions of the test object, resulting in relatively limited test results. Therefore, improvements are needed. Utility Model Content

[0026] In this embodiment, through the arrangement of the box 1, the water spray nozzle 2, the placement frame 9, the water collecting chamber 10, the water pump 11 and the water pipe 12, when the water spray nozzle 2 is of the existing structure, it can spray the experimental items installed thereunder to simulate rainfall. When testing the experimental items, the experimental items are placed in the placement frame 9, and the spray liquid is injected into the water collecting chamber 10. The spray liquid is pumped into the water spray nozzle 2 through the water pipe 12 by the water pump 11. The water spray nozzle 2 can then spray the experimental items on the placement frame 9, and cooperate with the rotation of the rotating plate 4 to allow the experimental items on the placement frame 9 to be tested by rain.

[0027] In this embodiment, a water inlet and a water outlet are respectively provided on both sides of the bottom of the box body 1, and a one-way valve is provided on the water inlet and the water outlet. The water inlet is used to inject spray liquid into the water collecting chamber 10, and the water outlet is used to discharge the spray liquid from the water collecting chamber 10 after the experiment is completed.

[0028] In this embodiment, through the arrangement of the partition 3, rotating plate 4, vertical plate 5, rod body 6, gear 7, support frame 8, clamping assembly and driving assembly, the vertical plate 5 is fixedly connected to the rotating plate 4, the rod body 6 is rotatably connected between the vertical plates 5 through a bearing, the gear 7 is fixedly connected to the rod body 6, the support frame 8 is fixedly connected to the gear 7, and the placement frame 9 is fixedly connected to the support frame 8. When the experimental item is placed in the placement frame 9, after the experimental item is fixed by the clamping assembly, the gear 7 can be driven to rotate by the driving assembly. The rotation of the gear 7 can drive the placement frame 9 to rotate, causing the placement frame 9 to tilt, thereby causing the experimental item in the placement frame 9 to tilt, and then the experimental item can be simulated in a tilted state to perform a rain test. By adjusting the rotation angle of the placement frame 9, the rain intensity test can be performed on multiple positions on the experimental item, thereby obtaining multiple experimental results.

[0029] In this embodiment, there is a gap between the partition 3 and the inner wall of the box body 1, and a water seepage groove is provided at the bottom of the placement frame 9 so that the spray liquid sprayed by the water nozzle 2 on the placement frame 9 can be discharged into the water collection chamber 10 in time for reuse.

[0030] See also Figures 1-6 In this embodiment, the clamping assembly includes a sliding rod 100 relatively arranged in the placement frame 9, and a splint 102 with both ends connected to the sliding rod 100 is relatively provided in the placement frame 9. The sliding rods 100 on both sides of the splint 102 are respectively provided with springs 103 for pushing the splints 102 closer to each other. A pull rod 104 extending through the placement frame 9 is respectively provided at the center of the splint 102, and a pull block 105 is provided on the pull rod 104 for pulling the splints 102 away from each other.

[0031] When the cam 102 is in the closed position, the cam 102 is in the closed position, and the cam 102 is in the closed position, so that the cam 102 is in the closed position and the cam 102 is in the closed position.

[0032] See also Figures 1-6 In this embodiment, the driving assembly includes a sliding plate 200 arranged between the vertical plates 5, and the sliding plate 200 is provided with a rack 201 meshing with the gear 7. Mounting blocks 202 are provided on both sides of the rotating plate 4, and a screw 203 with a thread passing through the sliding plate 200 is provided between the mounting blocks 202.

[0033] In this embodiment, the sliding plate 200, the rack 201, the mounting block 202, and the screw 203 are arranged. The mounting block 202 is fixedly mounted on the rotating plate 4, and the screw 203 is rotatably mounted between the mounting blocks 202 via a bearing. When the tilt angle of the placement frame 9 needs to be adjusted, the screw 203 can be rotated, thereby driving the sliding plate 200 to move, thereby moving the rack 201 on it, and driving the gear 7 to rotate, thereby adjusting the tilt angle of the placement frame 9, thereby tilting the test object, and allowing the water nozzle 2 to perform rain intensity tests on different positions on the test object;

[0034] Specifically, in order to facilitate the operator to drive the screw 203 to rotate, one end of the screw 203 passes through the corresponding mounting block 202 and extends out. A turning handle is provided at the extended end of the screw 203, and the turning handle is used to enable the operator to rotate the screw 203.

[0035] See also Figures 1-6 In this embodiment, a limit block 300 is relatively provided on the inner wall of the box body 1, a limit groove 301 is provided in the limit block 300, a lifting block connected to the partition 3 is provided in the limit groove 301, and a screw rod 302 threadedly connected to the lifting block and rotatable is provided in the limit groove 301.

[0036] In this embodiment, by setting the limit block 300, the limit groove 301, the lifting block and the screw rod 302, in actual use, the limit block 300 is fixedly installed on the inner wall of the box body 1 along the height direction of the box body 1, and the lifting block is slidably connected to the limit groove 301. The rotation of the screw rod 302 can drive the lifting block to rise and fall in the limit groove 301. Since the lifting block is fixedly connected to the partition 3, the lifting and lowering of the lifting block can drive the partition 3 to rise and fall. The distance between the placement frame 9 and the water nozzle 2 can be adjusted by lifting and lowering the partition 3, thereby adjusting the intensity of the spray water sprayed by the water nozzle 2 to the experimental item, so as to detect the experimental results of the experimental item under rainwater of different intensities.

[0037] See also Figures 1-6 In this embodiment, a shell is provided on the top of the box body 1, and the top end of the screw rod 302 is extended into the shell. A driving sprocket 303 and a driven sprocket 304 are respectively provided at the end of the screw rod 302 extending into the shell. A chain 305 is provided between the driving sprocket 303 and the driven sprocket 304. A first motor 307 for rotating the screw rod 302 is provided in the shell through a bracket 306.

[0038] In this embodiment, the bracket 306 is fixedly connected to the top of the box body 1 through the arrangement of the shell, the driving sprocket 303, the driven sprocket 304, the chain 305, the bracket 306 and the first motor 307. When the first motor 307 drives the screw rod 302 provided with the driving sprocket 303 to rotate, the two screw rods 302 rotate synchronously through the cooperation of the driving sprocket 303, the driven sprocket 304 and the chain 305, thereby driving the lifting block to be lifted and lowered synchronously in the limit groove 301, and then driving the partition 3 to be lifted and lowered.

[0039] See also Figures 1-6 In this embodiment, a rotatable round rod 400 is provided at the center of the partition 3, the upper end of the round rod 400 is provided with a base 401 connected to the rotating plate 4, and the lower end surface of the partition 3 is provided with a second motor 402 for driving the round rod 400 to rotate.

[0040] In this embodiment, through the arrangement of the round rod 400, the base 401 and the second motor 402, the round rod 400 is rotatably connected to the partition 3 through a bearing, the base 401 is fixedly connected to the upper end of the round rod 400, and the rotating plate 4 is fixedly connected to the base 401. The round rod 400 is driven to rotate by the second motor 402, which can drive the rotating plate 4 to rotate. The rotation of the rotating plate 4 can drive the placement frame 9 to rotate, thereby driving the experimental items in the placement frame 9 to rotate, so as to better simulate the all-round rain environment and ensure the comprehensiveness and accuracy of the test.

[0041] See also Figures 1-6 In this embodiment, a sealing door 13 that can be opened and closed is provided on the outside of the box body 1, and a handle is provided on the sealing door 13.

[0042] In this embodiment, the sealing door 13 and the handle are provided so that the sealing door 13 can be opened and closed, which can better facilitate the placement of experimental items in the box 1. Specifically, a rubber pad is provided on the edge of the sealing door 13 to improve the sealing effect between it and the box 1 and prevent the spray liquid from leaking. The sealing door 13 is provided with transparent glass for observing the experimental conditions inside the box 1, and the handle is used to open and close the sealing door 13.

[0043] Working principle: When the present invention is in use, the sealing door 13 is opened, the pulling block 105 is pulled to drive the splints 102 to move away from each other, and after the experimental object is placed between the splints 102, the pulling block 105 is released to clamp the experimental object through the splints 102. When it is necessary to test the rain intensity of the experimental object when it is placed at an angle, the screw 203 can be rotated at this time to drive the placement frame 9 to rotate, thereby tilting the experimental object in the placement frame 9, and then the sealing door 13 is closed, and then the second motor 402 and the water pump 11 are started to drive the placement frame 9 to rotate. At the same time, the water nozzle 2 sprays spray liquid to the experimental object, and the rain test of the experimental object can be carried out.

[0044] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of coverage of the present patent.
