Abstract
Description
Technical Field
[0001] This application relates to the technical field of viewing windows, and more particularly to a viewing window. Background Technology
[0002] A viewing window, also known as an observation window, is a transparent opening or device installed on a wall, door frame, container, equipment, or vehicle. Its main function is to allow observation of the internal state or external environment while maintaining physical isolation (such as isolation from pressure, temperature, hazardous substances, noise, etc.).
[0003] Currently, common observation windows on the market include those disclosed in patent publication number CN216950134U, which describes a quick-assembly soundproof and heat-insulating double-glazed cleanroom observation window. This window includes a rectangular frame, with observation glass positioned at the front and rear of the frame. A front rectangular side panel is positioned at the front of the outer side of the frame, a middle rectangular side panel is positioned at the middle of the outer side of the frame, and a rear rectangular side panel is positioned at the rear of the outer side of the frame. Several side fixing bodies are positioned on the outer side of the frame, and these side fixing bodies are fixedly installed to the front, middle, and rear rectangular side panels. A rectangular storage compartment is provided within each side fixing body.
[0004] Regarding the aforementioned technologies, the inventors discovered that the double-glazed glass is a flat glass, and the visible range is only the size of the double-glazed glass, resulting in poor visibility inside the cleanroom. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a window that improves visibility for personnel.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A window includes a window component and a mounting component disposed on the window component; The viewing window includes an upper transparent plate and a lower transparent plate arranged symmetrically, and a connecting frame is provided between the upper transparent plate and the lower transparent plate. The distance between the upper transparent plate and the lower transparent plate gradually decreases from the center to the periphery. The mounting component includes a bottom frame and a top frame disposed on the connecting frame, and a connector is provided between the bottom frame and the top frame.
[0007] To achieve the above technical solution, the distance between the upper and lower transparent panels gradually decreases from the center outwards, causing the upper and lower transparent panels to symmetrically arch outwards, forming a "convex lens" effect. This allows the viewing window to magnify the internal space, thereby improving visibility. Simultaneously, the "convex" shape ensures that when condensation occurs in the central area due to temperature differences, the condensate drips quickly under gravity, maintaining visibility. During installation, simply insert the bottom frame along with the viewing window into the door opening, then abut the bottom frame against the door, and finally fasten the top frame to the fastening plate. Finally, connect and lock the top and bottom frames together using connectors to complete the viewing window installation.
[0008] As a preferred embodiment of this application, a vacuum cavity is formed between the upper transparent plate, the lower transparent plate, and the connecting frame, and the vacuum cavity is evacuated.
[0009] To achieve the above technical solution, the vacuuming in this embodiment is performed using a commercially available vacuum machine to create a positive vacuum, rather than an absolute vacuum. At the same time, the vacuum period can provide a heat insulation effect, thereby reducing the occurrence of condensation on the outer and inner surfaces of the upper and lower transparent plates, and thus ensuring the visibility effect.
[0010] As a preferred embodiment of this application, the bottom frame is fixed to the connecting frame, and the connecting frame is provided with an upwardly folded fastening plate at the end away from the bottom frame. The top frame is fastened to the fastening plate, and a sealing decorative strip is provided between the top frame and the fastening plate.
[0011] To achieve the above technical solution, the design of the sealing decorative strip creates a labyrinthine seal between the top frame and the window component, ensuring both sealing and physical barrier effects. This also enhances the aesthetic appeal.
[0012] As a preferred embodiment of this application, the connector is configured as screws and nuts evenly spaced along the circumference of the connecting frame, and both the bottom frame and the bottom frame are provided with positioning holes for the screws and nuts to fit into.
[0013] The above technical solution is achieved by using a countersunk hole design for the positioning hole, which allows the screw and nut to be embedded inside, ensuring that the entire viewing window will not protrude and cause injury to personnel, while also improving aesthetics.
[0014] As a preferred embodiment of this application, reinforcing ribs are provided between the positioning holes.
[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The distance between the upper and lower transparent panels gradually decreases from the center to the perimeter, causing the upper and lower transparent panels to symmetrically arch outwards to form a "convex lens" effect. This makes the viewing window magnify the internal space, thereby improving the visibility for personnel. At the same time, the "convex" shape allows condensation to drip quickly under gravity when it occurs in the middle area of the surface due to the temperature difference between the inside and outside, ensuring visibility.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0022] This application discloses a window in its embodiments. (Refer to...) Figure 1 The window includes a window component 1 and a mounting component 2 disposed on the window component 1. The mounting component 2 is used to install the window component 1 on a door or other location where installation is required.
[0023] The viewing window 1 includes an upper transparent plate 11 and a lower transparent plate 12 symmetrically arranged, with a connecting frame 13 between them. The distance between the upper transparent plate 11 and the lower transparent plate 12 gradually decreases from the center to the periphery, causing the upper transparent plate 11 and the lower transparent plate 12 to symmetrically arch outward, forming a "convex lens" effect. This allows the viewing window 1 to magnify the internal space, thereby improving visibility. Simultaneously, the "convex" shape allows condensation to quickly drip off under gravity in the central area due to temperature differences, ensuring good visibility.
[0024] A vacuum chamber is formed between the upper transparent plate 11, the lower transparent plate 12, and the connecting frame 13. The vacuum chamber is evacuated; in this embodiment, the evacuation is performed using a commercially available vacuum machine to create a positive vacuum, not an absolute vacuum. This vacuum period also provides thermal insulation, reducing condensation on the outer and inner surfaces of the upper and lower transparent plates 11 and 12, thus ensuring visibility. The lower transparent plate 12 and the connecting frame 13 can be integrally injection molded, and then the upper transparent plate 11 is laser-welded to the connecting frame 13 for sealing.
[0025] Mounting component 2 includes a bottom frame 21 and a top frame 22 mounted on the connecting frame 13, with a connector between the bottom frame 21 and the top frame 22. The bottom frame 21 is fixed to the connecting frame 13, and an upward-folding fastening plate 23 is provided at the end of the connecting frame 13 away from the bottom frame 21. The top frame 22 is fastened to the fastening plate 23, and a sealing decorative strip 24 is provided between the top frame 22 and the fastening plate 23. During installation, the bottom frame 21, along with the viewing window component 1, is inserted into the opening of the door, the bottom frame 21 is pressed against the door, the top frame 22 is fastened to the fastening plate 23, and then the top frame 22 is connected and locked to the bottom frame 21 using the connector, thus completing the installation of the viewing window. Simultaneously, the design of the sealing decorative strip 24 creates a labyrinthine seal between the top frame 22 and the viewing window component 1, ensuring a sealing and physical barrier effect while also enhancing aesthetics.
[0026] The connectors are screws and nuts evenly spaced along the circumference of the connecting frame 13. Both the top frame 22 and the bottom frame 21 have positioning holes 25 for the screws and nuts to fit into. These positioning holes 25 are countersunk, ensuring the screws and nuts are properly seated and preventing any protrusions in the viewing window that could cause injury, while also improving aesthetics. To ensure structural strength, reinforcing ribs 26 are provided between the positioning holes 25.
[0027] The implementation principle of a viewing window in this application embodiment is as follows: the distance between the upper transparent plate 11 and the lower transparent plate 12 gradually decreases from the center to the periphery, thereby making the upper transparent plate 11 and the lower transparent plate 12 symmetrically arch outward to form a "convex lens" effect, which makes the viewing window 1 magnify the internal space, thereby improving the visibility of people; at the same time, the "convex" shape allows condensation to fall quickly under the action of gravity when condensation occurs in the middle area of its surface due to the temperature difference between the inside and outside, ensuring the visibility effect; during the installation process, it is only necessary to insert the bottom frame 21 together with the viewing window 1 into the opening of the door, then abut the bottom frame 21 against the door, and then fasten the top frame 22 onto the fastening plate 23, and then connect and lock the top frame 22 and the bottom frame 21 through the connector, thereby completing the installation of the viewing window.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
