Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to an electromagnetic shielding fireproof cleanroom panel. Background Technology

[0002] With the rapid development of industries such as electronic information, biomedicine, and precision manufacturing, the demand for cleanrooms, as critical production and experimental environments that strictly control parameters such as airborne particle concentration, temperature, humidity, pressure difference, and electromagnetic environment, is increasing daily. Cleanroom panels, as the core enclosure material for cleanroom walls and ceilings, directly determine the cleanroom's grade, safety, and functionality. Traditional cleanroom panels primarily focus on two basic properties: "cleanliness" (e.g., smooth surface, dust-free, corrosion-resistant) and "fire resistance" (e.g., meeting building fire resistance requirements). However, in specific application scenarios such as data centers, communication equipment rooms, medical imaging rooms, aerospace testing laboratories, and precision instrument processing workshops, in addition to the above requirements, extremely high demands are placed on "electromagnetic shielding" performance. Electromagnetic shielding aims to prevent external electromagnetic interference from affecting sensitive indoor equipment or to prevent leakage of electromagnetic signals generated by internal equipment, and is crucial for ensuring information security and normal equipment operation.

[0003] Existing electromagnetic shielding fireproof cleanroom panels have the following problems: First, traditional cleanroom panels are usually spliced ​​using simple plug-in or screw connections. This method is not only inefficient and difficult to align, but also makes it difficult to achieve continuous and stable electrical connections, resulting in a decrease in electromagnetic shielding performance at the joints and creating weak points for electromagnetic leakage. Second, the connection structure of existing cleanroom panels is prone to loosening after long-term use or vibration, affecting the flatness and sealing of the overall structure, thereby reducing its fireproof and cleanliness performance. In addition, the composite structure of multi-layer functional materials (such as conductive layer, fireproof layer, and shielding layer) and frame often has insufficient bonding strength, and is prone to delamination under temperature differences or stress, affecting the integrity and service life of the panel. Finally, existing installation limiting and fixing methods are relatively simple and lack an effective longitudinal and lateral dual limiting mechanism, which makes the panels prone to displacement or warping during installation and use, making it difficult to meet the strict requirements of high-standard cleanrooms for wall flatness, airtightness, and long-term stability.

[0004] Therefore, an electromagnetic shielded fireproof cleanroom panel is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an electromagnetic shielding fireproof cleanroom panel to solve the problems mentioned in the background art regarding the defects in splicing connection, structural stability, material composite strength, and installation limiting mechanism of the existing electromagnetic shielding fireproof cleanroom panels, which make it difficult for their electromagnetic shielding continuity, overall structural reliability, and long-term performance to meet high standards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic shielded fireproof cleanroom panel, comprising an outer frame, wherein a functional layer is compositely disposed inside the outer frame; One side of the outer frame is provided with a female groove, and the opposite side is provided with a male head that mates with the female groove; The two ends of the female groove are provided with a snap-fit ​​connection mechanism. The snap-fit ​​connection mechanism includes a snap-fit ​​connection seat fixedly connected to the end of the female groove and an elastic locking buckle that can be engaged inside the snap-fit ​​connection seat. The elastic locking buckle is used to fixally connect with the other adjacent outer trim frame.

[0007] Preferably, the functional layer includes a conductive transition layer, a fireproof and heat-insulating core material, and a main shielding layer stacked sequentially.

[0008] Preferably, the snap-fit ​​connection mechanism further includes a U-shaped stop bar fixedly disposed on the snap-fit ​​connection seat, and the snap-fit ​​connection seat and the U-shaped stop bar are integrally injection molded.

[0009] Preferably, the outer frame is provided with an installation limiting groove, which is composed of a semi-rectangular groove and a semi-cylindrical groove; When the two outer trim frames are joined together, the mounting limiting grooves on their joining surfaces are spliced ​​together to form a complete groove. A longitudinal stop block is provided in the installation limiting groove, and the width of the longitudinal stop block is the same as the width of the semi-rectangular groove portion of the installation limiting groove.

[0010] Preferably, the mounting limiting grooves are symmetrically opened on both sides of the top of the outer frame near the elastic locking buckle, and the top of the longitudinal stop block is provided with a protrusion.

[0011] Preferably, the outer trim frame is made of a conductive material or a non-conductive material with a conductive coating on its surface.

[0012] Preferably, the conductive transition layer, fireproof and heat-insulating core material, and main shielding layer are fixedly connected to the outer frame by bonding, pressing, or in-mold composite molding.

[0013] Preferably, the fireproof and heat-insulating core material is one of rock wool, glass wool, aluminum silicate fiber wool, or aerogel felt.

[0014] Preferably, the main shielding layer is one of a metal wire mesh, a metal foil, a conductive coating layer, or a conductive composite material layer.

[0015] Preferably, the elastic locking buckle is made of a flexible metal material or engineering plastic, and includes an engaging part and a connecting part. The engaging part is used to engage with the space formed by the buckle connecting seat, and the connecting part is used to fix it to an adjacent clean plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This electromagnetic shielding fireproof cleanroom panel, through the setting of a conductive outer frame with a snap-fit ​​connection mechanism and a composite functional layer structure, achieves rapid splicing, stable connection, and stable electrical connection of the cleanroom panel, effectively improving electromagnetic shielding performance, installation flatness, and fireproof sealing performance. The specific details are as follows: Firstly, this invention achieves rapid alignment and stable connection during panel splicing by setting a female groove on one side of the outer frame of the cleanroom panel and a male head on the opposite side, and configuring a snap-fit ​​connection mechanism consisting of a snap-fit ​​connector, a U-shaped stop strip, and an elastic locking snap at the end of the female groove. This not only improves installation efficiency but also ensures a continuous and stable electrical connection at the joint through the conductive properties of the outer frame and the tight fit of the snap-fit ​​connection mechanism. This effectively solves the problem of electromagnetic shielding performance attenuation caused by traditional plug-in or screw connection methods, and prevents the joint from becoming a weak point for electromagnetic leakage. At the same time, the installation limiting groove on the outer frame, which is composed of a combination of semi-rectangular grooves and semi-cylindrical grooves, forms a complete groove after the panels are joined. Combined with the double limiting effect of the longitudinal stop block, a reliable longitudinal and lateral limiting mechanism is constructed, which improves the flatness and positional stability of the panels after installation, prevents displacement or warping during use, and meets the strict requirements of high-standard cleanrooms for wall flatness.

[0017] Secondly, this utility model adopts a composite functional layer structure in which a conductive transition layer, a fireproof and heat-insulating core material, and a main shielding layer are stacked in sequence. It is firmly fixed to the outer frame through bonding, pressing, or in-mold composite molding, which improves the bonding strength between the multi-layer functional materials and the frame and effectively avoids the delamination phenomenon that is prone to occur under temperature difference or stress, thus ensuring the integrity and service life of the board. At the same time, the synergistic effect of the snap-fit ​​connection mechanism and the installation limiting groove makes the board form a tight sealing structure after splicing, reducing the generation of gaps. Combined with the high-efficiency fireproof and heat-insulating performance of the fireproof and heat-insulating core material, it further improves the fireproof and cleanliness performance of the board. Moreover, the elastic characteristics of the elastic locking snap can adapt to slight vibrations during long-term use, preventing the connection structure from loosening and ensuring the sealing and stability of the overall structure. This solves the problems of easy loosening and poor sealing performance of existing cleanroom board connection structures. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figure 1-9 As shown, the present invention provides an electromagnetic shielded fireproof cleanroom panel with an outer frame 1 as the basic load-bearing structure. The panel has a functional layer inside and a splicing mechanism outside to achieve rapid assembly and fixation of multiple panels. The functional layer consists of a conductive transition layer 2, a fireproof and heat-insulating core material 3, and a main shielding layer 4, stacked sequentially from top to bottom (or from outside to inside, depending on the actual application scenario). These three layers are fixedly connected to the outer frame 1 using an in-mold composite molding method (adhesion or pressing methods can also be selected according to production needs, both ensuring connection strength and structural stability). The fireproof and heat-insulating core material 3 is made of rock wool, possessing excellent fire-retardant and heat-insulating properties; the main shielding layer 4 uses metal mesh, exhibiting stable conductivity and achieving efficient electromagnetic shielding; the conductive transition layer 2 uses a conductive coating layer to optimize the conductive continuity between the functional layer and the outer frame 1. The outer frame 1 is made of aluminum alloy with a conductive coating (meeting conductivity requirements while also being lightweight). One side has a female groove 5 integrally formed, and the opposite side has a male connector 6 that matches the female groove 5. The dimensions of the female groove 5 and male connector 6 are strictly matched to ensure a tight fit when the two cleanroom panels are joined. Simultaneously, symmetrical installation limiting grooves 10 are provided on both sides of the top of the outer frame 1 near the elastic locking buckle 9. These installation limiting grooves 10 are integrally formed from a semi-rectangular groove and a semi-cylindrical groove, with a longitudinal stop block 11 inside. The width of the longitudinal stop block 11 is exactly the same as the width of the semi-rectangular groove portion of the installation limiting groove 10, and its top has an integrally formed protruding structure for easy gripping and force application during operation.

[0022] The snap-fit ​​connection mechanism includes a snap-fit ​​connector 7, a U-shaped baffle 8, and a resilient locking snap 9. The snap-fit ​​connector 7 is fixedly connected to both ends of the female groove 5 by welding. The U-shaped baffle 8 and the snap-fit ​​connector 7 are manufactured using an integral injection molding process to ensure structural integrity and connection strength. The resilient locking snap 9 is made of stainless steel with good elasticity. It includes an integrally molded engaging part and a connecting part. The size of the engaging part is adapted to the internal space formed by the snap-fit ​​connector 7. The connecting part is fixedly connected to the corresponding position of the outer frame 1 of the adjacent cleanroom panel by bolts. The conductive properties of the outer frame 1, together with the conductive transition layer 2 and the main shielding layer 4 in the functional layer, form a complete conductive shielding system. The conductive transition layer 2 effectively eliminates the conductive gap between the outer frame 1 and the main shielding layer 4. The metal mesh structure of the main shielding layer 4 can block the penetration of external electromagnetic signals and prevent the leakage of internal electromagnetic signals, thus achieving efficient electromagnetic shielding. The fireproof and heat-insulating core material 3 in the functional layer is made of rock wool, which is non-combustible and heat-resistant. It can block the spread of flames and heat transfer in a fire scenario. Combined with the flame-retardant treatment of the outer frame 1, it ensures that the cleanroom panel as a whole meets the specified fire resistance rating. When two cleanroom panels are joined, initial positioning is achieved through the precise cooperation of the female groove 5 and the male connector 6. The engaging part of the elastic locking buckle 9 is engaged inside the buckle connecting seat 7 of the adjacent panel. The U-shaped baffle 8 forms a lateral limit on the elastic locking buckle 9 to prevent its lateral displacement. At the same time, the installation limiting groove 10 is spliced ​​to form a complete groove. After the longitudinal stop block 11 is inserted into the groove, its cooperation with the semi-rectangular groove restricts the longitudinal movement of the outer frame 1. Through the dual limitation of lateral and longitudinal movement, the structural stability of the two cleanroom panels after splicing is ensured, and loosening during use is prevented.

[0023] Working principle: Before using this type of electromagnetic shielded fireproof cleanroom panel, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 9 As shown, during installation, first fix the first cleanroom panel in the preset installation position, then align the male end 6 of the second cleanroom panel with the female groove 5 of the first cleanroom panel, and slowly push it in to make them fit together; at this time, the elastic locking buckle 9 on the second cleanroom panel engages with the buckle connecting seat 7 of the first cleanroom panel, and the U-shaped stop 8 forms a lateral limit on the elastic locking buckle 9; subsequently, align the longitudinal stop block 11 with the installation limiting groove 10 formed after the two cleanroom panels are joined, rotate the longitudinal stop block 11 to offset it from the semi-rectangular groove part of the groove body, insert it into the groove and then release it. The longitudinal stop block 11 forms a longitudinal limit with the groove body through its own structure, completing the installation and fixing of the two cleanroom panels. The installation of multiple panels can be achieved by repeating the above steps in sequence. When it is necessary to disassemble the cleanroom panel, first, hold the protrusion on the top of the longitudinal stop block 11 and apply rotational force to rotate the longitudinal stop block 11 so that its structure is fully matched with the semi-rectangular groove of the mounting limiting groove 10; then, pull the longitudinal stop block 11 outward along the groove axis to release its longitudinal limitation on the outer trim frame 1; next, pull the outer trim frame 1 to be disassembled vertically upward, causing the elastic locking buckle 9 to move longitudinally inside the buckle connecting seat 7. During this process, ensure that the elastic locking buckle 9 does not contact the U-shaped stop bar 8, thereby releasing the lateral limitation of the U-shaped stop bar 8 on the elastic locking buckle 9; finally, continue to pull the outer trim frame 1 so that the elastic locking buckle 9 is completely disengaged from the buckle connecting seat 7, and at the same time, pull the male head 6 out of the female groove 5 to achieve the disassembly and separation between the two cleanroom panels.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
