Description

Technical Field

[0001] This utility model relates to the field of cleanrooms, specifically a modular cleanroom. Background Technology

[0002] Prefabricated cleanrooms are enclosed spaces with specific cleanliness levels and air purification functions, constructed on-site through rapid connection and assembly processes using prefabricated cleanroom walls, ceilings, doors, windows, air conditioning and purification systems, based on standardized and modular design concepts. They can be widely used in industries with high environmental cleanliness requirements, such as electronics, pharmaceuticals, food, and bioengineering.

[0003] Traditional modular cleanrooms rely primarily on through bolts to secure the panels to the frame using edge-sealing frames. After installation, the heads of these bolts are typically exposed to the cleanroom's internal and external environment. This exposure not only affects the overall aesthetics but, more importantly, the thread gaps and head grooves easily become hiding places and breeding grounds for dust, microorganisms, and other contaminants. Furthermore, because the bolt heads are exposed, they may deteriorate over time due to humidity, detergents, or other corrosive agents, leading to potential sealing failure and impacting the cleanroom's pressure differential stability and overall airtightness. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a modular cleanroom to solve the technical problem that when the splicing panels are fixed by the edge sealing frame in traditional modular cleanrooms, the bolt heads are exposed and easily accumulate dirt and grime, and are susceptible to environmental corrosion and aging, which may lead to potential sealing failure risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular cleanroom, comprising a main frame, splicing panels, and an edge-sealing frame for fixing adjacent splicing panels;

[0006] The edge banding frame includes an edge banding frame body, the outer surface of which has a first bolt groove and the adjacent side has a second bolt groove, and the bolt passes through the first bolt groove and the second bolt groove to fix the splicing plate.

[0007] The inner front ends of the first bolt groove and the second bolt groove are rotatably connected to a sealing plate via a torque shaft. A sealing plate groove is provided on the side of the first bolt groove and the second bolt groove away from the torque shaft, and the sealing plate groove is used to support the sealing plate. A magnetic absorbing sheet is adhered to the outer surface of the sealing plate, and a magnetic absorbing groove is provided on the magnetic absorbing sheet. The magnetic absorbing groove can be magnetically attracted to an external magnet, and the sealing plate can be easily opened after being magnetically attracted.

[0008] By adopting the above technical solution, and by setting up the edge sealing frame and its first bolt groove, second bolt groove, and bolts, reliable fixing of adjacent splicing plates is achieved. The key improvement lies in the sealing plate, which is rotatably connected to and mounted on the sealing plate groove via a torsion shaft, and the magnetic absorbing sheet with magnetic grooves adhered to its outer surface. This effectively hides and protects the bolt heads, isolates them from pollutant deposition and environmental corrosion, and at the same time, utilizes the magnetic attraction between the magnetic grooves and external magnets to achieve convenient opening and closing of the sealing plate, facilitating bolt maintenance.

[0009] Furthermore, the main frame, splicing plate, and edge banding frame are all made of aluminum alloy, and the sealing plate can be used to hide and protect the bolts.

[0010] By adopting the above technical solution, combined with the concealing and protective function of the sealing plate, the overall structure is lighter, more corrosion-resistant, and easier to install and disassemble. At the same time, it clarifies that the core function of the sealing plate is to conceal and protect the bolts, directly addressing the core technical solution to the problem of traditional exposed bolts.

[0011] Furthermore, the main frame includes a base frame and a top frame, which together form a cuboid frame via side vertical frame rods.

[0012] By adopting the above technical solutions, the splicing panels and capping panels provide a stable and standardized geometric foundation installation structure, simplify the overall assembly process, improve structural rigidity and stability, and ensure effective enclosure of the cleanroom space.

[0013] Furthermore, the splicing panel includes a first splicing panel, a door frame, a window frame, a viewing window, a second splicing panel, and a top panel, which are respectively installed on the side and top of the main frame.

[0014] By adopting the above technical solutions, five types of side panels—first splicing panel, door frame, window frame, viewing window, second splicing panel, and top panel—provide standardized modular units covering walls, doors, windows, and ceilings, making it easy to select and combine them according to the cleanroom layout requirements.

[0015] Furthermore, the viewing window is a component of the splicing panel and is fixedly connected to adjacent splicing panels via an edge banding frame.

[0016] By adopting the above technical solutions, it is ensured that the viewing window and the wall panel use the same edge-sealing frame connection method, and their connection points can also be completely covered and hidden by the sealing plate, maintaining the continuous sealing and cleanliness of the overall enclosure.

[0017] Furthermore, the top of the top frame is provided with multiple fixing rods, and the multiple fixing rods are fixedly connected to the top wall.

[0018] By adopting the above technical solution, the top frame is firmly anchored to the top wall by fixing rods, providing strong upper support for the entire main frame and preventing structural displacement or deformation.

[0019] Furthermore, the top of the top frame is provided with a mounting slot, and multiple top plates are mounted in the mounting slot.

[0020] By adopting the above technical solution, the mounting groove provides precise positioning, load-bearing and limiting for the top plate, making it stable and forming a flat and continuous top surface, and enhancing the overall rigidity of the top plate.

[0021] Furthermore, the first splicing plate, the second splicing plate, and the capping plate are all made of engineering plastics.

[0022] By adopting the above technical solutions, engineering plastic materials enable lightweight installation of panels, with smooth and easy-to-clean surfaces, resistance to chemical corrosion, and good insulation, making them suitable for clean environment requirements and reducing the risk of material contamination.

[0023] In summary, the present invention has the following main advantages:

[0024] This invention features a sealing frame with a first and second bolt groove for bolts to pass through and fix the splicing plate. A sealing plate is rotatably connected to the front end of the bolt groove via a torque shaft. When maintenance or disassembly is required, the sealing plate can be easily lifted to expose the bolts using an external magnet that attracts the magnetic groove. After the operation is completed, the sealing plate automatically rotates under the torque of the torque shaft and embeds itself into the sealing plate groove. The magnetic strip on its outer surface ensures a secure closure. During this process, the sealing plate completely covers and hides the bolt groove and bolt head, solving the technical problem of traditional prefabricated cleanrooms where exposed bolt heads easily accumulate dirt and form pollution dead corners, are susceptible to environmental erosion and aging, and thus pose a potential risk of sealing failure at the connection point. At the same time, it maintains a flat and aesthetically pleasing appearance and simplifies daily maintenance. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A type of modular cleanroom, such as Figure 1-4 As shown, it includes a main frame 1, splicing panels 2, and an edge banding frame 3 for fixing adjacent splicing panels 2;

[0032] The edge banding frame 3 includes an edge banding frame body 301. The edge banding frame body 301 has a first bolt groove 302 on its outer surface and a second bolt groove 303 on the adjacent side. Bolts 304 pass through the first bolt groove 302 and the second bolt groove 303 to fix the splicing plate 2.

[0033] A sealing plate 306 is rotatably connected to the inner front end of the first bolt groove 302 and the second bolt groove 303 via a torque shaft 305. A sealing plate groove is formed on the side of the first bolt groove 302 and the second bolt groove 303 away from the torque shaft 305, and this groove is used to hold the sealing plate 306. A magnetic sheet is adhered to the outer surface of the sealing plate 306, and a magnetic groove 307 is formed on the magnetic sheet. The magnetic groove 307 can be magnetically attracted to an external magnet, and after magnetic attraction, it is easy to open the sealing plate 306. After the bolt 304 is fixed, the sealing plate 306 is rotatably connected to the torque shaft 305. The shaft 305 automatically rotates and closes, with its edge mounted in the groove of the sealing plate. It is then attracted and fixed by the magnetic groove 307 on the magnetic sheet on the outer surface of the sealing plate 306, forming a complete concealment and coverage of the first bolt groove 302, the second bolt groove 303, and the heads of the bolts 304 inside, effectively preventing external pollutants from entering and moisture from corroding the bolts. When maintenance or disassembly is required, the sealing plate 306 can be lifted by using an external magnet to attract the magnetic groove 307 to overcome torque and magnetic attraction, exposing the bolts 304 for operation. After maintenance, it automatically closes and re-adsorbs.

[0034] See Figure 3 , Figure 4The main frame 1, splicing plate 2, and edge banding frame 3 are all made of aluminum alloy. The sealing plate 306 can be used to hide and protect the bolts 304. The main frame 1, splicing plate 2, and edge banding frame 3 are made of aluminum alloy, which provides a lightweight structure for easy transportation and installation, and has excellent corrosion resistance to resist the erosion of cleaning agents in clean environments, ensuring long-term structural reliability. This material supports the sealing plate 306 to effectively hide and protect the bolts 304, eliminating the risk of pollutant accumulation and environmental erosion caused by the exposure of the bolts 304.

[0035] See Figure 1 , Figure 4 The main frame 1 includes a base frame 101 and a top frame 102. The base frame 101 and the top frame 102 form a cuboid frame through side vertical frame rods. The cuboid frame formed by the base frame 101, the top frame 102 and the side vertical frame rods creates a standardized installation interface, which facilitates the subsequent positioning and installation of various splicing panels 2 and the top plate 206. It also supports the overall frame with its own structural rigidity, ensuring the safety and reliability of the cleanroom's load-bearing capacity.

[0036] See Figure 4 The splicing panel 2 includes a first splicing panel 201, a door frame 202, a window frame 203, a viewing window 204, a second splicing panel 205, and a top panel 206, which are respectively installed on the side and top of the main frame 1. By predefining these standard component types, such as the door frame 202 with pre-set door openings and the viewing window 204 with integrated observation windows, users can directly select the required modules for assembly without customizing non-standard components, simplifying the supply chain and accelerating the construction of the enclosure structure of the cleanroom's functional areas, equipment areas, passages, and cleaning areas.

[0037] See Figure 1 The viewing window 204 is a component of the splicing panel 2. It is fixedly connected to the adjacent splicing panel through the edge sealing frame 3. As a type of splicing panel 2, the viewing window 204 is connected to the adjacent splicing panel through the edge sealing frame 3, ensuring that its surrounding connection method is consistent with other walls. This allows the bolt 304 fixing point to be hidden and covered by the sealing plate 306 driven by the torque shaft 305, maintaining no pollution dead corners in this area and ensuring that the window structure is integrated into the overall sealing of the wall panel.

[0038] See Figure 1 , Figure 4 The top of the top frame 102 is provided with multiple fixing rods 103, and the multiple fixing rods 103 are fixedly connected to the top wall. The multiple fixing rods 103 on the top frame 102 are fixedly connected to the top wall of the room, providing reliable downward support and horizontal restraint for the main frame 1, especially the top frame 102, effectively resisting the structural self-weight and external load, preventing the top frame 102 from sinking and shifting, and ensuring the stability of the overall clean room frame space.

[0039] See Figure 3 , Figure 4The top of the top frame 102 is provided with a mounting groove 104, in which multiple top plates 206 are mounted. The mounting groove 104 on the top of the top frame 102 precisely accommodates and supports the top plates 206, ensuring that the multiple top plates 206 are accurately positioned and stably installed, forming a flat top surface with no height difference and seamless fit. The groove structure also supports and enhances the overall bending strength of the assembled top plates 206.

[0040] See Figure 1 , Figure 2 The first splicing panel 201, the second splicing panel 205, and the top panel 206 are all made of engineering plastics. The use of engineering plastics in the first splicing panel 201, the second splicing panel 205, and the top panel 206 reduces the weight of the panels and facilitates handling and installation. The material characteristics provide a smooth and easy-to-clean surface, resistance to corrosion from common cleaning agents, and electrical insulation, which perfectly meets the cleanroom requirements for panel cleanliness and chemical stability, reducing the possibility of the panels becoming a source of contamination, and complementing the function of the aluminum alloy frame.

[0041] The implementation principle of this embodiment is as follows: First, bolts 304 are used to pass through the first bolt groove 302 on the outer surface of the edge sealing frame 301 and the second bolt groove 303 on the adjacent side in sequence to firmly fix the adjacent splicing plates 2.

[0042] After fixing, the sealing plate 306 automatically rotates and closes under the torque of the torque shaft 305 connected to it, so that its edge is accurately mounted in the sealing plate groove opened on the side of the first bolt groove 302 and the second bolt groove 303 away from the torque shaft 305.

[0043] Meanwhile, the magnetic strips and magnetic grooves 307 on the outer surface of the sealing plate 306 are attached to the corresponding parts of the edge sealing frame 301, thereby completely covering and hiding the first bolt groove 302, the second bolt groove 303 and the bolt 304 head inside them under the sealing plate 306, effectively isolating external dust, pollutants and moisture from corrosion.

[0044] When maintenance or disassembly is required, simply align the external magnet with and attach it to the magnetic groove 307. Overcoming the torque and magnetic attraction of the torque shaft 305, the sealing plate 306 can be easily rotated outward to expose the bolt 304, making operation convenient.

[0045] After the operation is completed, remove the external magnet. Under the torque of the torque shaft 305, the sealing plate 306 automatically resets, closes, and is magnetically fixed, restoring the hidden protection state.
