[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-6As shown, a rain test machine spray angle adjustment device includes a test machine body 1, and a spray mechanism 2 is arranged inside the test machine body 1. The test machine body 1 includes a motor 109; the spray mechanism 2 includes a mounting frame 201, of which three mounting frames 201 are provided. Several branch pipes 202 are fixedly connected to the inner side of each mounting frame 201. Each branch pipe 202 is equidistantly arranged along the width direction of the side of the mounting frame 201, and each branch pipe 202 has a nozzle 203 on its surface. Each nozzle 203 is equidistantly arranged along the length direction of the branch pipe 202, and the inner wall of the nozzle 203 is threaded; a main pipe 204 is also embedded and fixed to the side of the mounting frame 201. One side of the main pipe 204 is fixed and connected to the branch pipe 202. A support pipe 205 is fixed and connected to the middle of the side of the main pipe 204 away from the branch pipe 202. A sealing ring 206 is fixedly connected to the end of the support pipe 205. Figure 5 As shown, nozzles of different shapes can be additionally installed through the threads inside the nozzle 203;

[0028] The main body 1 of the testing machine also includes a casing 101. The top of the inner wall of the casing 101 is fixedly installed with a single mounting frame 201. Extension plates 114 are fixedly connected to both sides of the middle section of the inner wall of the casing 101. The sides of the two extension plates 114 are rotatably connected to the middle sections of different mounting frames 201. A knob 115 is rotatably connected to the surface of the extension plate 114. The knob 115 passes through the extension plate 114 at the pivot and is fixedly connected to the mounting frame 201. A threaded rod 116 is threadedly connected to the surface of the extension plate 114 above the knob 115. A stop block 117 is rotatably connected to the bottom end of the threaded rod 116. Figure 5 As shown, the abutment 117 is in close contact with the knob 115, thereby preventing the mounting frames 201 located on both sides from rotating;

[0029] The back of the chassis 101 is connected to and fixedly connected to the topmost support pipe 205. The back of the chassis 101 is also connected to and rotatably connected to the support pipes 205 on both sides below. All the ends of the support pipes 205 are connected to a four-way pipe 207. Multiple valves are installed on the outside of the four-way pipe 207 to control water flow. The side of the four-way pipe 207 is fixedly connected to the back of the chassis 101. Figure 2 As shown, the support pipes 205 and the four-way pipe 207 on both sides are rotatably connected to each other. The sealing ring 206 can reduce the connection gap and thus prevent pipe leakage.

[0030] The inner walls of the chassis 101 are provided with clearance grooves 104 at the upper and lower ends on both sides. The inner walls of the clearance grooves 104 extend away from the mounting frame 201. A door 102 is hinged to the upper front of the chassis 101. An observation window 103 is also inlaid and fixed on the surface of the door 102. Figure 1 , Figure 3 As shown, the arrangement of the clearance slot 104 increases the maximum rotation angle of the mounting frame 201;

[0031] A support plate 105 is fixedly connected to the lower end of the inner wall of the chassis 101. A water storage tank 112 is fixedly connected to the inner wall of the chassis 101 and below the support plate 105. A drain pipe 113 is fixedly connected to the lower end of the side of the chassis 101, and the end of the drain pipe 113 is connected through the interior of the water storage tank 112. Figure 3 As shown, a valve structure is installed inside the drain pipe 113;

[0032] The surface of the support plate 105 has several drain outlets 106, and the top surface of the support plate 105 also has slide rails 107 on both sides. A sliding seat 108 is slidably connected to the inner side of the slide rails 107. A motor 109 is fixedly installed in the middle of the inner wall of the sliding seat 108. The output end of the motor 109 extends upward through the sliding seat 108 and is fixedly connected to a support plate 110. A support mesh 111 is inlaid and fixedly fixed to the side surface of the support plate 110. The upper part of the outer wall of the sliding seat 108 is sloped around its perimeter. Figure 1 , Figure 6 As shown, the sliding seat 108 above the support plate 105 can be installed according to the requirements of the product to be tested. The product can also be tested by placing it directly on the support plate 105. The motor 109 is a commonly used device in the prior art. The specific model needs to be purchased according to the test requirements, so it will not be described in detail here.

[0033] The working principle of this utility model:

[0034] When using the device, first place the product to be tested on the support plate 110. Then, start the motor 109 to rotate the support plate 110 and adjust the product orientation. When adjusting the angle of the two spray mechanisms 2, turn the threaded rod 116 to lift itself and the stop block 117 through its surface threads. Then, rotate the mounting frame 201 as a whole by turning the knob 115. When the angle needs to be fixed, turn the threaded rod 116 in the opposite direction so that the stop block 117 abuts against the knob 115. Depending on the testing requirements, the fan-shaped nozzle or the cone-shaped nozzle can be used. The water is installed into the threaded grooves in the nozzle 203. Then, by connecting the output end of the external water pump to the four-way pipe 207 and opening the valve on the corresponding side inside the four-way pipe 207, the water flows into the interior of each support pipe 205, then through the column pipe 204 and the branch pipe 202, and finally simulates rainwater through the nozzle 203 or the nozzle output. The simulated rainwater can wash different surfaces of the product to be tested. The falling rainwater enters the water storage tank 112 through the drain outlet 106, and finally is discharged by opening the valve of the drain pipe 112.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
