Description

Technical Field

[0001] This utility model relates to a purification window for use in clean rooms. Background Technology

[0002] Cleanrooms have strict requirements for air cleanliness, and the sealing performance of the purification window, as a key component connecting the indoor and outdoor environments, directly affects the cleanroom environment.

[0003] Currently, existing cleanroom windows are cumbersome to assemble, increasing the workload for workers and manufacturing costs for manufacturers. Furthermore, the lack of a seal between the glass panel and the window frame results in poor sealing performance, allowing dust from outside to easily enter the cleanroom and negatively impacting the cleanroom environment. Therefore, a new type of cleanroom window needs to be designed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a purification window for cleanrooms, which has a reasonable structure, is easy to assemble, and has the advantages of good sealing performance. It is suitable for high-cleanliness places such as biopharmaceutical and electronic chip manufacturing.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a purification window for cleanrooms, including a window frame and a glass panel.

[0006] The window frame includes a base frame and two sealing frame plates. The base frame has a receiving opening in the middle and receiving grooves communicating with the receiving opening on both sides. The glass plate is placed in the receiving opening. The two sealing frame plates are respectively placed in the two receiving grooves and are fixedly connected to the base frame by snap-fit. The inner surface of the sealing frame plate has a first annular sealing groove. The first annular sealing groove has a first annular sealing strip that abuts against the bottom of the receiving groove. The inner surface of the sealing frame plate has a convex ring located inside the first annular sealing groove. The inner surface of the convex ring has a second annular sealing groove. The second annular sealing groove has a second annular sealing strip that abuts against the glass plate.

[0007] Preferably, each side of the sealing frame plate is provided with a retaining strip, the inner surface of the retaining strip is a beveled structure, and the groove wall of the receiving groove is provided with a retaining groove for engaging with the retaining strip.

[0008] Preferably, the basic frame is an aluminum alloy frame.

[0009] Preferably, the sealing frame plate is a stainless steel plate, and the retaining strip is a stainless steel elastic retaining strip.

[0010] Preferably, the glass plate is a double-layered laminated glass plate.

[0011] The advantages and beneficial effects of this utility model are as follows: It provides a purification window for cleanrooms, which has a reasonable structure, is easy to assemble, and has the advantage of good sealing performance. It is suitable for high-cleanliness places such as biopharmaceutical and electronic chip manufacturing. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows:

[0017] like Figure 1 and Figure 2 As shown, a cleanroom window includes a window frame and a glass panel 1.

[0018] The window frame includes a base frame 2 and two sealing frame plates 3. The base frame 2 has a receiving opening 4 in the middle, and receiving grooves 5 communicating with the receiving opening 4 are respectively provided on both sides of the base frame 2. The glass plate 1 is placed in the receiving opening 4. The two sealing frame plates 3 are respectively placed in the two receiving grooves 5, and the two sealing frame plates 3 are fixedly connected to the base frame 2 by snap-fit. The inner surface of the sealing frame plate 3 has a first annular sealing groove 6. The first annular sealing groove 6 has a first annular sealing strip 7 that abuts against the bottom of the receiving groove 5. The inner surface of the sealing frame plate 3 has a convex ring 8 located inside the first annular sealing groove 6. The inner surface of the convex ring 8 has a second annular sealing groove 9. The second annular sealing groove 9 has a second annular sealing strip 10 that abuts against the glass plate 1.

[0019] Furthermore, each side of the sealing frame plate 3 is provided with a retaining strip 11, the inner surface of the retaining strip 11 is a beveled structure, and the groove wall of the receiving groove 5 is provided with a retaining groove 12 for engaging with the retaining strip 11.

[0020] Furthermore, the basic frame 2 is an aluminum alloy frame.

[0021] Furthermore, the sealing frame plate 3 is made of stainless steel, and the retaining strip 11 is made of stainless steel elastic retaining strip.

[0022] Furthermore, the glass plate 1 is a double-layered laminated glass plate.

[0023] In this invention, a purification window for a cleanroom is assembled as follows: a base frame 2 is pre-installed in the wall; a glass plate 1 is placed in the receiving opening 4 of the base frame 2; and two sealing frame plates 3 are placed in the receiving grooves 5 respectively, so that the locking strips 11 of the sealing frame plates 3 engage with the locking grooves 12, thereby fixing the sealing frame plates 3 to the base frame 2. The glass plate 1 is then clamped and fixed by the two sealing frame plates 3, completing the assembly of the purification window. Furthermore, when the sealing frame plates 3 are installed in place, the first annular sealing strip 7 is pressed between the sealing frame plate 3 and the bottom of the receiving groove 5, and the second annular sealing strip 10 is pressed between the convex ring 8 and the glass plate 1, thereby improving the sealing performance between the window frame and the glass plate 1.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
