[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1-4The present invention provides a technical solution for a crystal dust-proof and moisture-proof packaging device: a crystal dust-proof and moisture-proof packaging device, the structure of which includes a glass outer shell 1, wherein the interior of the glass outer shell 1 is provided with a tubular cavity 11 and a receiving cavity 12 which are arranged vertically therethrough, the tubular cavity 11 and the receiving cavity 12 being connected, and the intersection portion thereof is provided with an arc chamfer transition; end caps 2 are provided on the upper and lower sides of the glass outer shell 1, and the side edges of the end caps 2 are provided with recessed grooves, and a sealing ring 3 is installed in the recessed grooves;

[0026] During assembly, the rubber rod 4 is inserted into the tubular cavity 11 , which mainly plays the role of cushioning and facilitating the removal of the crystal 5 to be protected. The crystal 5 to be protected is inserted into the accommodating cavity 12 .

[0027] Among them, since this device is used to store crystals, the glass outer shell 1 is made of glass material, and the end cover part also needs to be made of special materials. The end cover 2 is a glass window made of ultraviolet quartz material. The inner and outer surfaces of the end cover 2 are coated with anti-reflection film, which has an effective protective effect. This device uses a sealing ring and a glass cavity to seal the optical crystal, effectively achieving the dust and moisture-proof effect of the crystal.

[0028] See attached for details Figure 1 and 3 , inward steps are provided at both ends close to the end caps 2, but since it is necessary to effectively protect the upper and lower ends of the crystal, a safety distance is provided between the crystal 5 to be protected and the end caps 2 on both sides, that is, when the crystal 5 to be protected is inserted into the accommodating cavity 12, its length is shorter than the length of the accommodating cavity 12, and then the filling limit is achieved by pressing the rubber rod 4, which facilitates the preservation state.

[0029] See Figure 1 The side of the end cap 2 is provided with an inward groove, in which a sealing ring 3 is installed. The inward groove can be an O-shaped groove or a V-shaped groove, and the sealing ring 3 can be an O-ring. High-quality O-rings are easy to obtain and have strong adaptability, which can achieve good moisture and dustproof effects.

[0030] Taking an LBO crystal as an example, one longitudinal edge of the LBO crystal is chamfered during use. A small, smooth, circular tubular cavity 11 is machined into the inner wall of the glass cavity (the chamber within the glass housing), into which a limiting rubber rod 4 can be inserted. The entire package, excluding the LBO crystal, consists of three parts: a glass cavity and two glass windows, made of two materials (glass and O-rings). The glass windows (end caps) are made of UV fused quartz with an antireflection coating on both sides. Special features include O-grooves or V-grooves machined into the sides of the circular glass windows, creating an air gap between the LBO crystal and the glass window, both for safety reasons and for air gap protection.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
