Description

Technical Field

[0001] The invention belongs to the field of glove box structure design, in particular to a front window sealing method of a glove box. Background Art

[0002] The glove box is a laboratory equipment that fills a sealed box with high-purity inert gas and circulates to filter out the active substances in it. The device has the characteristics of creating a vacuum, dust-free, and water-free ultra-pure environment, and is also called a vacuum glove box, an inert gas protection box, a dry box, etc. The main function is to remove O2, H2O, and organic gases. It is widely used in anhydrous, oxygen-free, and dust-free ultra-pure environments, such as: lithium-ion batteries and materials, semiconductors, OLED / PLED development and production, supercapacitors, special lamps, laser welding, brazing, material synthesis, inorganic / organic chemistry research, MOCVD, etc. It also includes biological applications, such as anaerobic bacteria culture, cell hypoxia culture, food microbiology testing, etc. This product is an ideal device for scientific experiments in colleges and universities, scientific research institutions, and corporate laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical industry, geology, mining, medicine and other departments. The current glove box structure generally embeds the window panel in the glove box body, and then pre-embeds screws at uniform distances on the outer edge of the window panel, installs a sealing strip on the inner edge of the panel, and then places the entire glass on the inner edge, and then places the pre-bent and spliced ​​pressure plate on the outer edge. By tightening the screws, the pressure plate squeezes the glass, and the glass squeezes the sealing strip to prevent leakage in the glove box. However, this installation method makes the glove box surface have many screws, which is not very beautiful, and it is not easy to replace the window panel when it is contaminated. In response to the above problems, our company has developed a new front window sealing method for the glove box to solve the above technical problems. Summary of the invention

[0003] The technical solution adopted by the present invention to solve the technical problem is: a front window sealing method of a glove box, including a glove box body, a flange window is opened on the front of the body, a sealing groove is processed inside the flange window, a transparent window panel is pressed on the groove, a double-layer O-ring is used to seal between the transparent window panel and the flange window, a bushing is pressed on the edges of the transparent window panel, a fixed pressing plate is pressed on the bushing, and the fixed pressing plate presses the transparent window panel on the flange window through a connecting flange. A decorative plate is installed on the fixed pressing plate, and the decorative plate is installed on the side of the glove box body that is previously left empty by screws. Furthermore, the transparent window panel and the flange window are sealed by a double-layer O-ring; further, the flange window is integrally processed, and the flange and the box body are automatically laser welded, and the one-time welding is formed; further, the decorative plate is installed on the side of the glove box body that is pre-empted by screws; further, the O-ring is a solid sealing ring, the sealing ring is hot-melted as a whole, there is no breakpoint on the surface, the seam, and the sealing is strong. The beneficial effect of the present invention is that the window can be easily disassembled and the user can install it separately, without the need for professional installation by the manufacturer, it is easy to operate, there is no installation screw on the outer surface of the decorative plate flange, and the overall appearance is beautiful. The overall leakage rate of the box is controlled at <0.0006vol% / h. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Specific implementation method: The technical scheme in the embodiment of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present invention. Please refer to the figure, the present invention provides a technical scheme: a front window sealing method of a glove box. It includes a glove box body 1, a flange window 3 is opened on the front of the body 1, a sealing groove is machined inside the flange window 3, a transparent window panel 6 is pressed on the groove, and a double-layer O-ring 2 is used to seal between the transparent window panel 6 and the flange window 3. A bushing 5 is pressed on the edges of the transparent window panel 6, and a fixed pressing plate 4 is pressed on the 5 surfaces of the bushing. The fixed pressing plate 4 presses the transparent window panel 6 on the window 3 through a connecting flange. A decorative plate 7 is installed on the fixed pressing plate 4, and the decorative plate 7 is installed on the side of the glove box body that is previously left empty by screws. Furthermore, the transparent window panel and the flange window are sealed by a double-layer O-ring; Furthermore, the flange window is integrally processed, and the flange and the box body are automatically laser welded, and the welding is formed in one go; Furthermore, the decorative panel is installed on the pre-empted side of the glove box body by screws; Furthermore, the O-ring is a solid sealing ring, the sealing ring is hot-melted as a whole, there are no breakpoints on the surface, the seams are strong in sealing; Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
