[0023] Reference Figure 1 As shown, an air tightness detection device for an air chamber toy includes a bottom plate 1, a lifting plate 2, and a top plate 3 arranged from bottom to top. The bottom plate 1 and the top plate 3 are connected by a support plate 4, and the lifting plate 2 can be elastically raised and lowered.

[0024] The bottom plate 1 is provided with a first base 5, which is provided with a first groove 51 open upward. The lifting plate 2 is provided with a second base 6 on the side facing away from the first base 5, which is provided with a second groove 61 open upward.

[0025] A driving module 7 is provided on the top plate 3, and a cover plate 8 is provided at the output end of the driving module 7. The cover plate 8 is driven to rise and fall by the driving module 7. When the cover plate 8 descends, it can seal the second groove 61 and push the lifting plate 2 to descend. The lifting plate 2 descends and then seals the first groove 51. When the cover plate 8 rises, the lifting plate 2 will rise autonomously, allowing the first groove 51 to be opened. When the cover plate 8 rises to a certain height, the cover plate 8 separates from the second base body 6, allowing the second groove 61 to be opened.

[0026] The first groove 51 and the second groove 61 are both connected to the input air pipe 9 and the pressure gauge 10. The first groove 51 is used to place the toy to be tested, and the second groove 61 is used to place similar toys with good airtightness. The total length of the input air pipe 9 of the first groove 51 and the air pipe required for connecting it to the pressure gauge 10 is the same as the total length of the input air pipe 9 of the second groove 61 and the air pipe required for connecting it to the pressure gauge 10.

[0027] After the first groove 51 and the second groove 61 are sealed, air is introduced into the first groove 51 and the second groove 61 at the same time, and the values of the two barometers 10 are observed to determine the pressure difference between the first groove 51 and the second groove 61. If the pressure difference exceeds a certain range, it is determined that the air tightness of the toy to be tested is poor, so that the air chamber of the toy is connected to the first groove 51. Through this device, the air tightness of the toy can be tested without getting the toy wet, eliminating the toy drying process and improving production efficiency.

[0028] In this embodiment, a first annular groove 52 is provided on the top of the first base body 5, and a first sealing ring is provided in the first annular groove 52.
