[0037] Please see Figure 1 and Figure 2 This utility model discloses a fire-resistant and durable composite board for filing cabinets, comprising two substrates 100 and a connecting assembly 200, wherein the two substrates 100 are connected by the connecting assembly 200. The two substrates 100 are spaced apart along their width direction. A fire-resistant and weather-resistant layer 110 is provided on the surface of each substrate 100, and slots 120 are provided on two opposite sides of each substrate 100 along its width direction. (See reference...) Figure 3 , Figure 4 and Figure 5The connecting assembly 200 includes two connectors 210, two connecting seats 220, and two cover plates 230. The two connectors 210 are disposed between two substrates 100, and each connector 210 is connected to one substrate 100 in a one-to-one correspondence. Each connector 210 has a snap-fit ​​protrusion 211 that extends into a corresponding snap-fit ​​groove 120. Each connector 210 has an insertion protrusion 212 at both ends along its length. The two connecting seats 220 are located at both ends of each connector 210 along its length, and the length of the connector 210 is consistent with the length of the substrate 100. The connecting seats 220 are used for mounting onto a support member, and each connecting seat 220 has a slot 221 into which the insertion protrusion 212 at the same end of each connector 210 extends. The two cover plates 230 are detachably connected to the two connectors 220 in a one-to-one correspondence. The cover plates 230 cover the slots 120 to prevent the insertion protrusions 212 from coming out of the slots 221.

[0038] The substrate 100 has fire-resistant and weather-resistant layers 110 on both sides, giving it fire-resistant and weather-resistant properties. Two adjacent substrates 100 are connected to form a whole by connecting components 200. Multiple substrates 100 can be spliced ​​together to form a larger board through multiple connecting components 200. During installation, the snap-fit ​​protrusion 211 is first installed into the slot 120, then the insertion protrusion 212 is inserted into the slot 221, then the connecting seat 220 is installed onto the support (which can be the support rib during installation), and finally the cover plate 230 is installed onto the connecting seat 220. When a single substrate 100 needs to be disassembled, the cover plate 230 is removed from the connecting seat 220, and then the substrate 100 is removed along its thickness direction, making disassembly and assembly convenient.

[0039] When installing the filing cabinets using fire-resistant and durable composite panels in this application, please refer to... Figure 6 and Figure 7 The connector 220 is fixed to the support member. The connector 220 and the connector 210 can support the substrate 100 or restrict the substrate 100 to the support member.

[0040] In some embodiments, see Figure 3 , Figure 4 and Figure 7 The cross-section of the insertion protrusion 212 is L-shaped, and the cross-section of the slot 221 is T-shaped. One slot 221 on the connector 220 corresponds to the insertion protrusion 212 of two connectors 210, so that the two connectors 210 can abut together, thereby making the gap between the two substrates 100 smaller.

[0041] In some embodiments, see Figure 3The snap-fit ​​protrusion 211 is provided with multiple barbs 2111. The snap-fit ​​protrusion 211 is inserted into the slot 120. The barbs 2111 can improve the connection stability between the snap-fit ​​protrusion 211 and the inner wall of the slot 120, making it less likely for the snap-fit ​​protrusion 211 to fall out of the slot 120, so that the connector 210 can be more stably connected to the substrate 100.

[0042] In some embodiments, see Figure 4 and Figure 5 The connector 220 has a threaded hole 222, and the cover plate 230 has a first connecting hole 231. Screws pass through the first connecting hole 231 and are screwed into the threaded hole 222. The cover plate 230 and the connector 220 are detachably connected by screws, making disassembly and assembly convenient.

[0043] In some embodiments, see Figure 4 and Figure 5 The connecting seat 220 is provided with a positioning groove 223, and the cover plate 230 is provided with a positioning protrusion 232, which extends into the positioning groove 223. The positioning protrusion 232 is engaged and connected in the positioning groove 223 to achieve the positioning connection between the cover plate 230 and the connecting seat 220.

[0044] In some embodiments, see Figure 4 The connector 220 has a second connecting hole 224, through which bolts are passed to connect to the support. During installation, bolts can be installed on the support first, then the bolts can be passed through the second connecting hole 224, and finally the nut can be tightened to secure the connector 220.

[0045] In some embodiments, see Figure 4 and Figure 5 The first connecting hole 231 is located on the bottom wall of the positioning groove 223. The depth of the positioning groove 223 is greater than the thickness of the positioning protrusion 232. The positioning protrusion 232 is provided with a clearance groove 2321. Two threaded holes 222 are provided, located on both sides of the positioning groove 223. The second connecting hole 224 is located on the bottom wall of the positioning groove 223. The bolt is installed on the support member, and the bolt passes through the second connecting hole 224 and extends into the positioning groove 223. The bolt is connected to the nut. The positioning protrusion 232 covers the positioning groove 223. The thickness of the positioning protrusion 232 is less than the depth of the positioning groove 223, and the positioning protrusion 232 is provided with a clearance groove 2321, so that the positioning protrusion 232 will not interfere with the nut and bolt.

[0046] In some embodiments, see Figure 4 and Figure 5The positioning groove 223 has a square cross-section, and the positioning protrusion 232 has a square cross-section. Since the positioning protrusion 232 and the positioning groove 223 have square cross-sections, the cover plate 230 will not rotate after the positioning protrusion 232 extends into the positioning groove 223, ensuring that the first connecting hole 231 corresponds to the threaded hole 222.

[0047] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The connector 210, connector 220 and cover plate 230 are all made of metal.

[0048] In some embodiments, see Figure 1 and Figure 2 The substrate 100 is one of particleboard, fiberboard, plywood, or blockboard. The composite board has a smooth and clean surface, making it easy to perform various forms of veneer or coating processes. This allows for diverse appearances, satisfying the aesthetic needs of different consumers. At the same time, the composite board is easy to cut, drill, and assemble, facilitating the processing into products of various shapes and sizes.

[0049] In some embodiments, see Figure 1 and Figure 2 The fire-resistant and weather-resistant layer 110 includes glass fiber cloth. Glass fiber cloth has high fire resistance; it does not burn, drip, shrink, or elongate when exposed to fire, and produces minimal smoke. It exhibits high and low temperature resistance, remaining stable under extreme temperatures. This material is lightweight yet high-strength, facilitating transportation and installation. The surface of the glass fiber cloth is smooth and aesthetically pleasing, available in a variety of colors, allowing users to select products with different colors and patterns according to their needs.

[0050] In some embodiments, see Figure 1 and Figure 2 The fire-resistant and durable composite board for filing cabinets also includes a shielding strip 300, which is located between two substrates 100 and adhered to the connector 210. A fire-resistant and weather-resistant coating is applied to the side of the shielding strip 300 away from the connector 210. The shielding strip 300 can shield the connector 200 and fill the gap between the two substrates 100, thereby improving the overall aesthetics of the composite board. The fire-resistant and weather-resistant coating is a melamine coating, which significantly improves the flame-retardant properties of the board and effectively slows the spread of flames. After curing, the melamine coating has good wear resistance, scratch resistance, and other physical properties, making the fire-resistant and durable composite board for filing cabinets more durable during use.
