[0021] A VOC emission testing device for automotive sound insulation cotton materials comprises a test box body 1, wherein a test inner box 2 is integrally formed at the upper left end of the test box body 1, and an auxiliary support plate 3 is provided at the lower middle position of the inner test box 2, and side frames 4 are provided at both sides of the top of the auxiliary support plate 3, a group of side frames 4 are connected by supporting ribs 5, an oblique bar 7 is fixedly connected to the top of the side frames 4, a collecting plate 8 is provided directly below the supporting ribs 5, and a limiting clamping strip 9 is fixedly connected to the bottom end of the collecting plate 8, and side buckle plates 10 are fixedly connected to both sides of the front end of the limiting clamping strip 9, and a control panel 15 is provided at the upper position of one side of the front end of the test box body 1.

[0022] like Figure 1 and Figure 2As shown, a sealed box door 13 is provided at the front position of the test inner box 2, and the sealed box door 13 is rotatably connected to the test box body 1 through a hinge, and an observation window 14 is clamped in the middle position of the sealed box door 13. When the device performs detection operations on the vehicle sound insulation cotton material, the staff can observe the current status of the sample through the observation window 14 which is made of a transparent material; transmission sliders 11 are fixedly connected to the two sides of the auxiliary support plate 3, and the transmission slider 11 is slidably connected to the test inner box 2, and a screw rod 12 is threadedly connected to the middle part of the transmission slider 11, and the screw rod 12 is rotatably connected to the test inner box 2. Since the screw rod 12 is connected to a driving device installed inside the test box body 1 during assembly, when it is necessary to adjust the height position of the auxiliary support plate 3, it is only necessary to start the driving device so that the transmission structure composed of the transmission slider 11 and the screw rod 12 can move the auxiliary support plate 3 up and down, and the height position of the auxiliary support plate 3 can be quickly adjusted.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, a side opening 6 is formed in the middle of the side frame 4 through integral molding, and the connection between the side opening 6 and the side frame 4 forms a "U"-shaped structure. A group of side frames 4 are fixedly connected to the collecting plate 8 respectively. By providing the side opening 6, this arrangement will facilitate the air to pass through the inside of the side opening 6 first, and then pass evenly through the reserved gaps between the multiple supporting ribs 5; the supporting ribs 5 are distributed in an equidistant structure along the horizontal direction, the top surface of the collecting plate 8 is provided with a "V"-shaped groove structure, and the upper half of the collecting plate 8 is provided with a limiting card strip 9 with a conical structure. A card groove for the limiting card strip 9 to be engaged and connected is provided in the middle of the auxiliary support plate 3, and the auxiliary support plate 3 and a group of side buckle plates 10 are fixedly connected with bolts, which will facilitate the VOC emission test device for vehicle sound insulation cotton materials to be able to be used When testing, a support structure composed of a plurality of supporting ribs 5 and a group of side frames 4 is used to provide support for the test sample. At the same time, the support process also facilitates the centralized falling of waste chips, so that the subsequent device can complete the testing operation of the vehicle sound insulation cotton material by quickly and independently disassembling and taking out the supporting structure, so as to conveniently realize the cleaning operation of the support structure table surface.
