The invention relates to a rigid constraint structure applied to an injection molding liner interface of a high-pressure gas cylinder, which comprises a valve seat, a radial sealing ring, a first rigid structure and an axial sealing ring, and the valve seat comprises a first connecting part, a flange plate and a second connecting part; a first annular groove is formed in the periphery of the second connecting part around the second connecting part, and the radial sealing ring is arranged in the first annular groove; the first rigid structural part comprises a platform and a protrusion, the protrusion can be inserted into the second connecting part, a through hole communicating with the cavity is formed in the first rigid structural part in the extending direction of the platform and the protrusion, and the platform can abut against the valve seat and the injection molding inner container connector. A second annular groove is formed in the face, abutting against the connector of the valve seat and the injection molding inner container, of the platform, and the axial sealing ring is arranged in the second annular groove. According to the rigid restraining structure, axial and annular bidirectional sealing can be achieved, relative deformation between sealing faces in the high-pressure gas storage environment is reduced, it is guaranteed that the compression ratio of the sealing ring is kept in an ideal state, and therefore the sealing effect is guaranteed.

The application discloses a method for fine modification of the interior of a crystal based on double-beam laser focus interference, and belongs to the field of laser precision machining. The method is realized by adjusting the divergence angle of double beams by using a laser shaping device to realize the overlap of focus A and focus B. The double foci overlap and interfere, and the interference phenomenon of the energy intensity alternately changing occurs in the focus overlap area; under the interference, laser energy is concentrated to the interference enhancement position, and the energy peak value can exceed the modification threshold of the material interior, and modification occurs; the size of the double-focus overlap area is compressed relative to the conventional single-focus area, and the modification by interference only occupies a part of the overlap area, and the size of the modification area is further compressed. Compared with the conventional single-focus modification area, the longitudinal size of the modification by the method can be compressed by at least 50%, and the precision of the micro-nano structure in the processed crystal is higher. According to the characteristics of the crystal material, laser parameters are selected, and scanning is carried out according to a preset track, modification points form a modification line, and then high-precision machining of a complex micro-nano structure in the crystal can be realized.
