Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and more specifically to a double-glazed steel window with good sealing performance. Background Technology

[0002] Cleanrooms have specific requirements for indoor cleanliness, and are equipped with filters. A steel double-glazed window is typically used on one side of the room for air exchange. Traditional steel double-glazed windows generally have poor sealing performance, largely due to their structural design. Traditional hinged steel double-glazed windows often place the sealing ring on the outer edge of the inner frame. After prolonged opening and closing, this sealing ring at the outer edge of the inner frame is prone to compression and deformation. Since the sealing point is at the outer edge of the window, this deformation allows air to easily enter through the loosened sealing ring, leading to a decrease in sealing effectiveness. To improve the sealing performance of steel double-glazed windows, the inventors researched and proposed this solution. Utility Model Content

[0003] The purpose of this utility model is to provide a steel double-glazed window with good sealing performance in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A steel double-glazed window with good sealing performance includes an outer frame, an inner frame, and a locking assembly. The outer surface of the outer frame is provided with several outer edges, and the inner side of the outer frame is provided with an inner edge that seals with the inner frame. Several sealing rings are provided on the inner edge. Double-glazed glass is nested on the inner frame, and a locking assembly is provided on the inner frame. A lock opening that cooperates with the locking assembly is provided on the inner side of the outer frame. The inner frame is made of steel.

[0006] The steel double-glazed window of this invention enhances stability during installation through the outer edges of the outer frame. A notch is formed between adjacent outer edges, allowing for pre-locking protrusions at the installation location of the double-glazed window. These protrusions restrain the outer frame, preventing the double-glazed window from falling out. Multiple sealing rings are installed between the inner and outer frames to effectively improve sealing.

[0007] A preferred technical solution: The locking assembly includes a handle, a connecting rod, a gear, a wheel frame, and a locking plate. The handle rotates synchronously with the gear via the connecting rod. The gear is mounted on the wheel frame and meshes with the inner side of the locking plate.

[0008] A preferred technical solution: the gear meshing plate is displaced and engaged in the locking slot.

[0009] A preferred technical solution: the connecting rod is a prism structure.

[0010] A preferred technical solution: The sealing ring is divided into a first sealing ring and a second sealing ring. The first sealing ring is larger than the second sealing ring. The first sealing ring is installed on the inner frame, and the second sealing ring is installed on the inner edge.

[0011] A preferred technical solution: The side end of the inner frame is connected to the outer frame via a hinge.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention improves the sealing performance of double-glazed windows when closed by setting multiple sealing rings in conjunction with the inner and outer frames; and by forming notches between several outer edges on the outer frame, locking protrusions can be used to restrict the outer frame at the installation position to prevent the double-glazed windows from falling out, thereby improving the stability of the double-glazed windows after installation.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, this embodiment provides a steel double-glazed window with good sealing performance, including an outer frame 1, an inner frame 2, and a locking assembly 3. The outer surface of the outer frame 1 is provided with several outer edges 11, and the inner side of the outer frame 1 is provided with an inner edge 12 that seals with the inner frame 2. Several sealing rings are provided on the inner edge 12. Double-glazed glass 21 is nested on the inner frame 2, and the locking assembly 3 is provided on the inner frame 2. The inner side of the outer frame 1 is provided with a lock opening 4 that cooperates with the locking assembly 3.

[0023] Furthermore, the locking assembly 3 includes a handle 31, a connecting rod 32, a gear 33, a wheel frame 34, and a locking plate 35. The handle 31 rotates synchronously with the gear 33 via the connecting rod 32. The gear 33 is rotatably mounted on the wheel frame 34, and the gear 33 meshes with the inner side of the locking plate 35.

[0024] Furthermore, gear 33 engages with plate 35, which then shifts and engages with locking slot 4.

[0025] Furthermore, the connecting rod 32 has a prism structure.

[0026] Furthermore, the sealing ring is divided into a first sealing ring 22 and a second sealing ring 13. The first sealing ring 22 is larger than the second sealing ring 13. The first sealing ring 22 is installed on the inner frame 2, and the second sealing ring 13 is installed on the inner edge 12.

[0027] Furthermore, the side ends of the inner frame 2 are hinged to the outer frame 1 via hinges 5.

[0028] When the steel double-glazed window is closed, a portion of the inner frame 2 extends into the inner side of the outer frame 1. The displacement of the inner frame 2 is restricted by the inner edge 12, and the inner frame 2 and the outer frame 1 are locked together by the locking assembly 3. The overlapping part of the window is sealed by the first sealing ring 22 and the second sealing ring 13.

[0029] The principle of the locking assembly 3: Rotating the handle 31 causes the gear 33 to rotate on the wheel frame 34 via the connecting rod 32. The gear 33 meshes with the inner side of the locking plate 35, causing the locking plate 35 to move vertically and engage with the locking slot 4, which is shaped to fit the locking plate 35. The locking slot 4 has a U-shaped structure. When the locking plate 35 is inserted into the locking slot 4, pulling the handle 31 will restrict the locking plate 35 against the side of the U-shaped structure. Figure 5 The arrow in the image indicates the direction in which the inner frame 2 is pulled.
