The two ends of the snap-on block 301 are respectively connected to the side of the snap-on block 301 and the side wall of the docking block 201. The docking block 201 is aligned with the docking groove 202 and pressed. The snap-on block 301 retracts due to the pressure. When the snap-on block 301 passes through the docking groove 202, the spring 302 drives the snap-on block 301 to reset, so that the lower cover plate 104 and the upper cover plate 105 can be fixedly connected.

[0027] In one embodiment, Figure 1-Figure 5As shown, the unlocking component includes a connecting rope 401 and a pull ring 402.

In this way, the unlocking is completed, which is convenient for the next test.

[0028] In one embodiment, Figure 1-Figure 2 As shown, a sealing gasket is provided on the contact surface between the lower cover plate 104 and the upper cover plate 105 to play a sealing role and improve the accuracy of detection.

[0029] In one embodiment, Figure 1-Figure 2 As shown, a valve 103 is provided on the side of the stainless steel cylinder 102, and a pressure sensor is provided on the valve 103. The pressure sensor connected to the valve 103 monitors the pressure change inside the device in real time, so that the self-sealing performance of the self-healing rubber at different temperatures can be verified.

[0031] In one embodiment, Figure 1 and Figure 4 As shown, the inner walls of the holes are respectively provided with grids 106, and the grids 106 are used to facilitate the placement of films.

[0032] The above embodiment discloses a self-sealing performance testing device for self-healing rubber, wherein the self-sealing rubber is coated between the upper and lower layers of film (film size 300*300mm), and the coating process is consistent with the coating process of the self-sealing tire. The film is placed on the lower cover plate 104, and the upper cover plate 105 is covered and fixed by the docking assembly and the clamping assembly. A certain amount of gas is filled into the device through the valve 103. After the air pressure in the device reaches the test air pressure, the device is placed in a water tank to verify its air tightness to ensure that there are no leaks in the device and each connecting interface. Then, nails are inserted into the film, and the pressure sensor connected to the valve 103 monitors the pressure changes inside the device in real time. In this way, the self-sealing performance of the self-healing rubber at different temperatures can be verified. The pressure sensor and the temperature sensor can monitor the changes in the air pressure and temperature in the device before and after the test in real time, and the data is recorded.
