Technical Field

[0001] The utility model relates to the technical field of environmental test equipment, in particular to an automatic lifting structure of a rain test chamber. Background Art

[0002] The rain test chamber, also known as a rain test machine or a rain box, is mainly used to detect the waterproof performance of various products. It can provide a realistic simulation environment to test the performance and reliability of products in a humid environment.

[0025] In the present invention, a telescopic frame 13 and a telescopic sleeve 7 are provided. The telescopic frame 13 supports the top plate 8 by means of the cross frame 10, and at the same time, it can be lifted and lowered under the drive of the telescopic cylinder 12, so that it can drive the water supply pipe 9 and the spray plate 14 to achieve a height adjustment effect by means of the cross frame 10 and the top plate 8. And the structure is arranged outside the rain box 3 and will not come into contact with water. At the same time, in this way, the overall height of the equipment can be adjusted, so that it is not limited by the height of the equipment box body, and when transporting, the position of the top plate 8 can be adjusted to the lowest, which is convenient for the transportation and movement of the equipment;

[0026] In addition, when the top plate 8 moves, it will drive the telescopic sleeve 7 connected thereto to stretch or contract, so that while keeping the top plate 8 movable, the space between the top cover 6 and the top plate 8 can be sealed, ensuring that the rain test will not interfere with the outside or be interfered by the outside.

[0027] A transparent door panel 5 is provided on the front of the shower box 3. The transparent door panel 5 is connected to the shower box 3 in a transverse sliding manner, and a handle is provided on the end surface of the transparent door panel 5.

[0028] By providing the transparent door panel 5 , the transparent door panel 5 can be used to close the rain box 3 while observing the situation inside the rain box 3 using the transparent material, so as to facilitate monitoring of the test process.

[0029] A height detector 4 is provided on the side of the shower box 3 and the top plate 8. The height detector 4 is used to detect the height of the shower plate 14 from the material placing component 2.

[0030] By setting up a height detector 4, the height detector 4 is divided into a signal transmitting part arranged on the side of the rain box 3, and a signal receiving part arranged on the side of the top plate 8. When the position of the top plate 8 is adjusted, the corresponding distance between the two will also change, thereby achieving the purpose of detecting the distance between the spray plate 14 and the material placing component 2, and by being arranged on the outside, it will not come into contact with water.

[0031] A plurality of recovery tanks 15 are provided on the base 1 at positions inside the shower box 3. The recovery tanks 15 are connected to the water storage device inside the base 1.

[0032] By setting up the recovery tank 15, the recovery tank 15 can recover the accumulated water dropped during the rain test, and introduce the accumulated water into the water storage device in the machine base 1, and then use the water supply device in the rain machine base 1 to achieve the effect of recycling.

[0033] The material placement component 2 includes a turntable 201, a support rod 202 and a material placement plate 207. The turntable 201 is provided on the machine base 1 and has a built-in drive mechanism. The support rod 202 is provided on the turntable 201 and the top end is connected to the material placement plate 207. The material placement plate 207 is located under the spray plate 14.

[0034] By setting up the turntable 201 and the support rod 202, the turntable 201 can drive the material placing plate 207 to rotate through the support rod 202. The rotation allows the product to be more fully exposed to the rain, further ensuring the effect of the rain test. At the same time, the support rod 202 can keep a certain distance between the material placing plate 207 and the machine base 1. This method can prevent water droplets falling on the machine base 1 from splashing onto non-test parts of the product, causing the product test results to be affected.

[0035] Example 2

[0036] refer to Figure 4 Specifically, a clamping plate 203 is provided on the support rod 202, a threaded rod 204 is provided on the side of the clamping plate 203, a ball 205 is fitted in the clamping plate 203, and a connecting rod 206 connected to the material placing plate 207 is provided on the ball 205. The threaded rod 204 uses the clamping plate 203 to apply a clamping force to the ball 205;

[0037] In the present utility model, by using the clamping plate 203, the spherical ball 205, and the threaded rod 204 plays a limiting role on the clamping plate 203, enabling the clamping plate 203 to deform inward and fix the spherical ball 205. Correspondingly, the connecting rod 206 and the material placing plate 207 connected to the spherical ball 205 are also fixed. In this way, the angle of the material placing plate 207 can be adjusted so that it can be adjusted according to the specific requirements of the product, and it has a larger applicable range compared with the first embodiment.

[0038] A plurality of fixing holes 208 are formed in the material placing plate 207. The fixing holes 208 are arranged in a rectangular array, and threads are provided on the inner wall of the holes.

[0039] By providing the fixing holes 208, the product can be directly or indirectly fixedly connected to the material placing plate 207 by using the fixing holes 208, making the placement of the product more firm and avoiding the problems of the product shifting and falling due to the impact of water flow during the test.

[0040] Working principle:

[0041] Before the test, the angle of the material placing plate 207 is adjusted to a suitable position. At the same time, the product is connected to the material placing plate 207 through the fixing holes 208. Then, the transparent door panel 5 is closed, and the telescopic cylinder 12 is started to drive the telescopic frame 13 to move upward. The telescopic frame 13 drives the top plate 8 to move through the cross frame 10 at the top. The top plate 8 drives the spray plate 14 to move through the water supply pipe 9, so that the distance between the spray plate 14 and the product is moved to the required height. When the top plate 8 moves, the telescopic sleeve 7 is stretched, and the telescopic sleeve 7 seals between the top cover 6 and the top plate 8. Finally, the water supply component in the machine base 1 supplies water to the spray plate 14 through the hose 11 and the water supply pipe 9, and the accumulated water that falls is recycled through the recovery tank 15.

[0042] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
