[0029] The detection box 1 is provided with a water tank 2, which is a constant temperature water tank and has a through top. A control panel 12 is provided at the front end of the detection box 1.

[0030] The fixing mechanism 3 is installed on the inner bottom surface of the water tank 2. Figure 1 As shown, in this embodiment, three fixing mechanisms 3, bottles 4, and reaction tanks 8 are provided respectively. The gas emission of three different test sample amounts of water-based aluminum paint can be tested simultaneously.

[0031] like Figure 2 As shown, the fixing mechanism 3 includes a fixing rod 31 , a fixing disk 32 , an adjusting rod 33 , a fixing plate 34 and a side wall 35 .

[0032] The lower end of the fixing rod 31 is connected to the inner bottom surface of the water tank 2, and the upper end is connected to the fixing plate 32. The fixing plate 32 is disc-shaped, and two arc-shaped side walls 35 are arranged opposite to each other on its upper surface. Figure 3 As shown, the adjusting rod 33 includes a first rod 331, a second rod 332 telescopically sleeved inside one end of the first rod 331, and a spring 333 respectively abutting against the first rod 331 and the second rod 332 inside the first rod 331. The end of the first rod 331 away from the second rod 332 is connected to the inner arc surface of the side wall 35. The end of the first rod 331 can be set to an arc surface that matches the inner arc surface of the side wall 35, or the first rod 331 and the inner arc surface of the side wall 35 can be connected through an arc-shaped mounting seat. The end of the second rod 332 away from the first rod 331 is connected to the fixing plate 34. The fixing plate 34 is an arc-shaped plate that matches the outer surface of the bottle 4.

[0033] The spring 333 acts as a buffer. When the bottle 4 is installed, the spring 333 is compressed and the fixing plate 34 retracts. When the installation force is released, the fixing plate 34 extends under the elastic force of the spring 333 and abuts against the outer surface of the bottle 4 to achieve locking. In this way, the installation of bottles 4 of different diameters can be adapted to prevent tipping during measurement.

[0036] like Figure 1 As shown, the fixing ring 10 is sleeved on the thermostatic tube 72 of the connecting tube 7. The support rod 11 is connected between the fixing ring 10 and the detection box 1. The support rod 11 and the fixing ring 10 can ensure the stability of the thermostatic tube 72 and prevent the thermostatic tube 72 from tilting or falling off during the measurement process. The thermostatic tube 72 can accurately maintain a constant temperature, ensure that the sample to be tested that is transmitted or stored is in a suitable temperature environment, and prevent the accuracy of the test data from being affected by the increase or decrease in temperature.

[0037] The reaction tank 8 is connected to the thermostatic tube 72, and the upper end of the reaction tank 8 is connected to a pressure gauge 9, which displays the pressure change inside the reaction tank 8, indicating the amount of gas generated inside the reaction tank 8, and thus the gas generation amount of the water-based aluminum paint can be measured.
