Description

Technical Field

[0001] This utility model relates to a sealed structure for an inspection port, belonging to the field of home decoration. Background Technology

[0002] Ceiling access panels, as openable openings reserved for later maintenance in building decoration, are widely used in office buildings, shopping malls, hospitals, and residences. In order to balance aesthetics and functionality, access panels are usually covered and enclosed by metal or plastic frames and a middle cover plate. The frame is embedded in the reserved hole in the ceiling panel, and the cover plate is fixed by screws, clips, or magnetic attraction so that it can be opened when it is necessary to inspect or repair the pipelines and equipment in the ceiling.

[0003] In existing technologies, the mainstream solutions mostly use aluminum alloy frames with galvanized steel cover plates. The four corners of the frame are spliced ​​at 45°. Screws pass through the side walls of the frame and are screwed into the wooden blocks or keels. The cover plate is supported by the inner folded edge of the frame. Some high-end products add magnetic strips or hinges to the back of the frame so that the cover plate can be magnetically closed.

[0004] However, the above-mentioned structure has revealed many shortcomings during construction and long-term use: First, the installation process requires the pre-laying of wooden blocks or keels on the back of the ceiling panel. Construction workers need to bring tools such as electric drills and screwdrivers to drill holes and screw nails on site, which is cumbersome and inefficient. Moreover, the glue or nails between the wooden blocks and the ceiling panel are prone to loosening and falling off due to the humid environment. Second, the aluminum alloy frame is becoming thinner and thinner due to cost pressures. It is easily deformed and the paint is peeled off when it is bumped during transportation. The gaps at the corners are obvious on site, affecting the appearance and sealing. Third, the galvanized steel cover plate is not thick enough. After long-term use, the middle part sags, the paint peels off and there is a risk of rust, which is particularly prominent in humid environments. In addition, when disassembling and maintaining, screws on the frame need to be removed one by one with a screwdriver. The operating space is small, which is time-consuming and laborious and can easily damage the ceiling panel finish.

[0005] Therefore, there is an urgent need in this field for a ceiling access panel structure that can achieve rapid installation and disassembly without nails, glue, or tools, while also possessing high strength, corrosion resistance, and a flat and aesthetically pleasing appearance. Summary of the Invention

[0006] In view of this, the present invention provides an inspection port sealing structure to solve the above-mentioned problems existing in the prior art.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] An inspection port closure structure includes: a fixing frame, a cover plate, and multiple spring clips;

[0009] The fixed frame is adapted to the shape of the access panel. It consists of a support edge formed by the vertical side and the lower edge of the vertical side turning inward, and a fixed edge formed by the lower edge of the vertical side turning outward. The cover plate is set on the fixed frame through the support edge. Multiple spring clips are evenly distributed on the outer side of the vertical side. The free end of the spring clip extends outward to form an elastic arm.

[0010] The area enclosed by the supporting edge is smaller than the area of ​​the cover plate, while the area enclosed by the fixed edge is larger than the area of ​​the access port.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the fixing frame is formed by splicing together multiple T-shaped profiles after beveling at the corners; preferably, the T-shaped profiles are flame-retardant plastic with a wall thickness of 2-3mm.

[0013] Furthermore, the cover plate is a 7mm thick three-layer aluminum alloy honeycomb panel.

[0014] The beneficial effects of this utility model are:

[0015] This utility model combines a fixed frame with spring clips, enabling quick installation and disassembly of the access panel enclosure structure without nails, glue, or tools. The frame is not easily deformed and requires no additional timber, significantly shortening the construction period and reducing material and labor costs. It also maintains a flat and aesthetically pleasing appearance even after long-term use, thus comprehensively solving the problems of cumbersome installation and difficult disassembly in existing technologies.

[0016] Figure 1 This is a schematic diagram of the fixed frame structure of this utility model.

[0017] The attached diagram lists the components represented by each number as follows:

[0018] 1. Fixed frame; 2. Spring clip; 3. Vertical edge; 4. Supporting edge; 5. Fixed edge. Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figure 1 As shown, the inspection port closure structure includes: a fixing frame 1, a cover plate, and multiple spring clips 2;

[0021] The fixed frame 1 is adapted to the shape of the inspection port, and is generally rectangular. It consists of a vertical side 3 and a supporting side 4 formed by the inward folding of the lower edge of the vertical side 3 and a fixed side 5 formed by the outward folding of the lower edge of the vertical side 3. The cover plate is set on the fixed frame 1 through the supporting side 4. Multiple spring clips 2 are evenly distributed on the outer side of the vertical side 3. The free end of the spring clip 2 extends outward to form an elastic arm.

[0022] The area enclosed by the supporting edge 4 is smaller than the area of ​​the cover plate, while the area enclosed by the fixed edge 5 is larger than the area of ​​the access port.

[0023] After opening the access panel in the ceiling, take the corresponding closed structure, pry open the spring clip 2 upwards, and install the fixing frame 1 at the access panel. After the spring clip 2 returns to its original position, it will cooperate with the fixing edge 5 to clamp at the access panel. No drilling or glue is required. After the fixing frame 1 is installed, place the cover plate in the middle of the fixing frame 1, which will be supported by the supporting edge 4. The installation is then complete. When the ceiling needs to be inspected, simply lift the cover plate upwards and place it inside the ceiling or remove it directly for inspection. After the inspection is completed, put the cover plate back. Alternatively, the fixing and cover plate can be removed together by loosening the spring clip 2.

[0024] In another embodiment of this utility model, the fixing frame 1 is formed by cutting corners of multiple T-shaped profiles and splicing them together, with the edges integrally formed, making the structure more stable. The angle of the cut corner is determined according to the specific shape of the inspection port. For example, when the inspection port is rectangular, the angle of the cut corner is 45°.

[0025] In another embodiment of this utility model, the T-shaped profile is made of flame-retardant plastic with a wall thickness of 2-3mm. Compared with metal frames, it has a more delicate texture, will not peel off, and will not deform even if it is slightly bumped during transportation or installation.

[0026] In another embodiment of this utility model, the cover plate is a 7mm thick three-layer aluminum alloy honeycomb panel. In the prior art, the cover plate is mostly metal plate or gypsum board, which is relatively thin and prone to sagging in the middle. Moreover, metal materials are likely to rust after long-term use, and the paint on the surface will also peel off. The aluminum alloy honeycomb panel is composed of a three-layer structure formed by aluminum plates on both sides sandwiching an aluminum honeycomb core, which has a certain sound insulation and heat insulation effect and will not rust in a humid environment.

[0027] In another embodiment of this utility model, the spring clip 2 is punched and fixed to the outside of the vertical side 3 by a riveting machine, and the head and tail of the rivet are flat and do not protrude after punching.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
