Description

Technical Field

[0001] This utility model relates to the field of insulation boards, specifically to a high flame-retardant and high heat-resistant insulation board. Background Technology

[0002] Insulating boards, as materials that can block the passage of current, are mainly used in the automotive industry, electrical industry, and communication engineering. Because they can still provide a certain degree of insulation in high humidity environments, they greatly improve the electrical safety of operators and are therefore widely used. However, when electrical equipment malfunctions and causes a fire, the insulating board itself does not have fire-resistant properties and cannot prevent the fire from spreading. Furthermore, the electrical equipment is installed on top of the insulating board, causing the bottom of the equipment to be covered by the insulating board and unable to dissipate heat properly. Therefore, this application proposes a high flame-retardant and high heat-resistant insulating board. Utility Model Content

[0003] In view of the problems existing in the current high flame retardant and high heat resistant insulation board, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a high flame retardant and high heat resistant insulation board, which solves the problems that insulation boards cannot prevent the spread of fire, and that electrical equipment installed on top of insulation boards causes the bottom of the equipment to be covered by the insulation board and thus cannot dissipate heat properly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high flame-retardant and high heat-resistant insulating board, comprising a substrate, a heat dissipation plate disposed on the top of the substrate, a flame-retardant plate disposed on the bottom of the substrate, a fireproof layer disposed on the bottom of the flame-retardant plate, and an adhesive layer of phenolic resin material disposed between the substrate and the heat dissipation plate, between the substrate and the flame-retardant plate, and between the flame-retardant plate and the fireproof layer. A through heat dissipation channel is opened on the side of the heat dissipation plate, and multiple fins are uniformly and fixedly installed in the heat dissipation channel. Multiple heat dissipation slots are uniformly opened on the top of the heat dissipation plate, and connecting slots are opened at both ends of both sides of the heat dissipation plate. Z-shaped connectors are inserted into the four connecting slots, and the vertical parts of the four connectors are respectively attached to the two sides of the substrate.

[0006] Preferably, each connecting groove has a slot on both sides of its inner end, and each connector has a groove on both sides of its horizontal end. A locking block is movably inserted into each of the two grooves, and a spring is fixedly connected between each locking block and the inner wall of the corresponding groove.

[0007] Preferably, the vertical part of the connector has a threaded groove extending into the upper horizontal part on its side. Both sides of the inner end of the threaded groove have openings that communicate with the corresponding grooves. The inner ends of the two locking blocks are fixedly connected with top rods that pass through the corresponding springs and openings. A second bolt is threaded into the threaded groove.

[0008] Preferably, when the upper horizontal part of the connector is inserted into the connecting groove, the locking blocks in the grooves at both ends of the horizontal part of the connector can be engaged in the locking grooves on both sides of the inner wall of the connecting groove.

[0009] Preferably, when the second bolt is inserted into the bolt groove and the push rod passes through the through-hole and abuts against the side wall of the second bolt, the locking block at the other end of the push rod engages in the locking groove on the inner wall of the connecting groove.

[0010] Preferably, a first bolt is inserted through the lower horizontal section of each of the four connectors.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] The heat sink allows for bottom heat dissipation of the equipment on the insulation board, while the fireproof layer and flame-retardant board provide effective fire protection for the substrate. Furthermore, the phenolic resin adhesive layer maintains the integrity and dimensional stability of the board even at high temperatures, further preventing combustion. Finally, the entire board can be fixed in position by engaging the connectors with the connecting grooves on both sides of the heat sink. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-6 The high flame-retardant and high heat-resistant insulation board shown includes a substrate 1, a heat dissipation plate 2 disposed on the top of the substrate 1, a flame-retardant plate 3 disposed on the bottom of the substrate 1, a fireproof layer 4 disposed on the bottom of the flame-retardant plate 3, and phenolic resin adhesive layers 5 disposed between the substrate 1 and the heat dissipation plate 2, between the substrate 1 and the flame-retardant plate 3, and between the flame-retardant plate 3 and the fireproof layer 4. A through heat dissipation channel 6 is opened on the side of the heat dissipation plate 2, and multiple fins 7 are uniformly and fixedly installed in the heat dissipation channel 6. Multiple heat dissipation slots 8 are uniformly opened on the top of the heat dissipation plate 2, and heat dissipation slots 8 are opened at both ends of both sides of the heat dissipation plate 2. There are four connecting grooves 9, and each of the four connecting grooves 9 has a Z-shaped connector 10 inserted into it. The vertical parts of the four connectors 10 are respectively attached to both sides of the substrate 1. The heat dissipation plate 2 on the top of the substrate 1 can dissipate heat from the bottom of the device on the insulating plate. The flame retardant plate 3 and fireproof layer 4 on the bottom of the substrate 1 can effectively prevent fire from spreading. The phenolic resin adhesive layer 5 can further prevent the fire from burning. Finally, the entire plate can be fixed in position by using the first bolt 11 after the connectors 10 are engaged with the connecting grooves 9 on both sides of the heat dissipation plate 2.

[0024] To facilitate the movement of the locking block 14 within the groove 13, such as Figure 5 and Figure 6 As shown, each connecting groove 9 has a slot 12 on both sides of its inner end, and each connecting piece 10 has a groove 13 on both sides of its horizontal end. A locking block 14 is movably inserted into each of the two grooves 13. A spring 15 is fixedly connected between each locking block 14 and the inner wall of the corresponding groove 13. When the locking block 14 is pressed by an external force, it will move into the groove 13, thereby pressing the spring 15 in the groove 13. When the locking block 14 is not pressed by an external force, the spring 15 will release its elastic force to push one end of the locking block 14 to move into the groove 13 and engage in the corresponding slot 12.

[0025] In order for the card block 14 to be stably engaged in the card slot 12, such as Figure 5 and Figure 6As shown, the vertical part of the connector 10 has a threaded groove 16 extending into the upper horizontal part. On both sides of the inner end of the threaded groove 16, there are openings communicating with the corresponding grooves 13. The inner ends of the two locking blocks 14 are fixedly connected with push rods 17 that pass through the corresponding springs 15 and the openings. The threaded groove 16 is threaded with a second bolt 18, which can limit the position of the push rod 17.

[0026] In order to complete the insertion of the horizontal and vertical part above the connector 10 into the connector groove 9, such as Figure 5 and Figure 6 As shown, when the upper horizontal part of the connector 10 is inserted into the connector groove 9, the locking blocks 14 in the grooves 13 at both ends of the horizontal part of the connector 10 can be engaged in the locking grooves 12 on both sides of the inner wall of the connector groove 9.

[0027] To restrict the position of push rod 17, such as Figure 5 and Figure 6 As shown, when the second bolt 18 is inserted into the threaded groove 16 and the push rod 17 passes through the through-hole and abuts against the side wall of the second bolt 18, the locking block 14 at the other end of the push rod 17 engages in the locking groove 12 on the inner wall of the connecting groove 9. Thus, under the action of the second bolt 18, the push rod 17 cannot move into the threaded groove 16, thereby allowing the locking block 14 to be stably engaged in the locking groove 12.

[0028] Finally, in order to install the entire insulation board, such as Figure 1 and Figure 2 As shown, each of the four connecting parts 10 has a first bolt 11 inserted through it on its lower horizontal part, which allows the entire insulating board to be fixed in position.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
