[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 - Figure 6 As shown, the sealing structure for laboratory doors and windows includes a window frame 1 embedded in the laboratory window opening. A plurality of symmetrically arranged ear plates 2 are fixedly installed on the side of the window frame 1 facing outdoors. The free ends of the plurality of ear plates 2 are provided with through holes for external bolts to pass through. During installation, the user can pass the external bolts through the through holes through the ear plates 2, and then screw the ear plates 2 to the side walls of the window opening to fix the window frame 1.

[0023] A window sash 5 is rotatably connected to the inner wall of one side of the window frame 1, and soundproof glass 6 is installed in the window sash 5. The soundproof glass 6 is a double-layer structure, and a vacuum chamber evacuated to a vacuum state is left between the two layers of soundproof glass 6. When in use, the user can rotate the window sash 5 to open and close the window. The soundproof glass 6 is set to a double-layer structure and a vacuum chamber is provided between the two layers of soundproof glass 6. This can greatly improve the sound insulation effect and minimize the problem of noise in the external environment being transmitted into the laboratory and affecting the experimenters.

[0024] A snap-fitting structure is provided on the adjacent side of the sealing plate 3 and the window sash 5. The snap-fitting structure includes a first snap-fitting groove 4 provided on the sealing plate 3 and a second snap-fitting groove 7 provided on the side wall of the window sash 5 close to the sealing plate 3. The two snap-fitting structures are arranged in a corresponding position. A rubber sealing strip 8 is provided on the outer side of the two snap-fitting structures. A connecting portion 11 is integrally formed on the side of the rubber sealing strip 8 close to the snap-fitting structure. The overall cross-section of the rubber sealing strip 8 and the connecting portion 11 is a T-shaped structure. The two rubber sealing strips 8 are respectively snap-fitted and fixed to the first snap-fitting groove 4 and the second snap-fitting groove 7 through the connecting portion 11.

[0025] Several telescopic holes 12 are provided inside the connecting portion 11, and a sliding tube 13 is provided in the inner cavity of each telescopic hole 12. Both ends of the sliding tube 13 are slidably connected to sliding rods 14. The adjacent ends of the two sliding rods 14 are connected and fixed by springs 15 embedded in the sliding tube 13. The two sliding rods 14 are fixedly connected to the ends outside the sliding tube 13 with pads 16. When the spring 15 is in a compressed state, the distance between the two pads 16 at one end away from each other is smaller than the inner cavity width of the first slot 4 and the second slot 7. The end of the sliding rod 14 outside the sliding tube 13 abuts against the inner walls on both sides of the telescopic hole 12 through the pad 16.

[0026] It should be noted that the sealing structure for laboratory doors and windows is first used to fix the window frame 1 on the window hole through the ear plate 2, and then the window sash 5 with the soundproof glass 6 installed inside is rotatably connected to the inner wall of the window frame 1 through a hinge. After the window sash 5 is installed, the user squeezes the connecting portion 11 on both sides of the slide tube 13 from both sides to make the two slide rods 14 set in the connecting portion 11 slide toward each other, and squeezes the spring 15 to shrink until the width of the connecting portion 11 shrinks along the telescopic hole 12 to be smaller than the inner cavity width of the first card slot 4 and the second card slot 7, and then the connecting portion 11 on the two rubber sealing strips 8 can be squeezed to the first card slot 4. and the second card slot 7. At this time, the spring 15 rebounds under the action of its own restoring force, and pushes the sliding rods 14 at both ends to squeeze the connecting part 11, and cooperates with the inner side walls of the first card slot 4 and the second card slot 7 to clamp and fix the connecting part 11, so that the two rubber sealing strips 8 are respectively clamped and fixed on the sealing plate 3 and the window sash 5. When the window sash 5 is closed, the two rubber sealing strips 8 can squeeze each other to achieve sealing of the window. When the rubber sealing strip 8 is aged due to long-term use, the rubber sealing strip 8 can be pulled outward to pull the connecting part 11 out of the first card slot 4 and the second card slot 7, so that the user can replace the rubber sealing strip 9 conveniently.

[0027] Example 2

[0028] Further improvements were made based on Example 1, such as Figure 5 As shown: the two rubber sealing strips 8 are provided with a receiving hole 9 inside, and a magnetic plate 10 is fixedly installed in the receiving hole 9. The adjacent sides of the magnetic plates 10 installed on the two rubber sealing strips 8 have opposite magnetic properties.

[0029] Since magnetic plates 10 are provided in both rubber sealing strips 8, and the adjacent sides of the magnetic plates 10 installed on the two rubber sealing strips 8 have opposite magnetic properties, when the window sash 5 is closed to make the two rubber sealing strips 8 fit together, the magnetic plates 10 installed in the two rubber sealing strips 8 can be attracted to each other under the action of the magnetic field force, so that the two rubber sealing strips 8 fit tightly, further improving the sealing of the window.

[0030] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
