The airbag 10 is isolated from the fixed base 1 and the movable cover plate 2 by the upper and lower wooden boards 6.

[0039] The TPU airbag cyclic inflation and deflation test clamping device also includes a leather backing 7, which is located between the fixed base 1 and the movable cover plate 2 and is connected to the top surface of the fixed base 1 and the bottom surface of the movable cover plate 2. The airbag 10 is isolated from the fixed base 1 and the movable cover plate 2 by the upper and lower leather backings 7.

[0040] The wooden board 6 and the leather backing 7 can be respectively connected to the fixed base 1 and the movable cover 2 by adhesive bonding, and the installation and connection are convenient and the connection stability is high.

[0041] The linear sliding bearing 3 is mounted on the movable cover plate 2 by screws to achieve a stable and reliable connection.

[0042] The outer surface of the optical axis 4 and / or the inner surface of the linear sliding bearing 3 are coated with high temperature butter, so that the linear sliding bearing 3 can be conveniently sleeved on the outer surface of the optical axis 4, and the lifting and lowering movement of the movable cover plate 2 is convenient, and the use is very convenient.

[0043] In this embodiment, the number of the optical axes 4 and the number of the linear sliding bearings 3 are both four, and the four optical axes 4 are arranged at the four corners of the movable cover plate 2, so that the movable cover plate 2 can move up and down smoothly.

[0044] Specifically, the fixed base 1 is a stainless steel plate, and circular holes of the same size are respectively opened at the four corners of the fixed base 1, and the hole diameter is slightly larger than the thread diameter of the hexagonal bolt. A part of the hole is milled off to hide the screw head, and the fixed base 1 is polished on the surface and corners by a milling machine. The movable cover plate 2 is also a stainless steel plate, which is slightly thinner than the fixed base 1. Perforations are correspondingly opened at the four corners of the movable cover plate 2, and the aperture of the perforation is the diameter of the optical axis.
