Description

Technical Field

[0001] This utility model relates to the field of fireproof and explosion-proof panels, and in particular to a fireproof and explosion-proof panel that is easy to install. Background Technology

[0002] Fireproof and explosion-proof panels are a special material made of reinforced fiber cement board with pressure-galvanized steel on the surface. They have fire resistance and explosion-proof properties. Explosion-proof panels are lightweight and high-strength, and can provide effective protection without increasing the structural load. Fireproof and explosion-proof panels are widely used in various systems such as explosion-proof partitions, explosion-proof ceilings, explosion-proof smoke exhaust ducts, cable pipes, and explosion-proof cable protection, and are an important part of building safety.

[0003] A search revealed Chinese Patent Publication No. CN221523868U, which discloses an easy-to-install fireproof and explosion-proof panel. The panel has a first arc-shaped groove and a second arc-shaped groove respectively formed on its upper, lower, left, and right sides. When the first and second panels are joined, the first arc-shaped groove and the corresponding second arc-shaped groove can form a large arc-shaped groove. Arc-shaped rods are slidably installed in the first arc-shaped groove. When disassembling any one of the fireproof and explosion-proof panels, only the central shaft needs to be rotated to separate the first and second panels. The disassembly method is convenient and does not require starting disassembly from the top or bottom of the fireproof and explosion-proof panel, meeting practical needs and suitable for widespread application.

[0004] In the above technical solution, the two sets of arc grooves on the plate and the central shaft can be used to facilitate the disassembly of the upper and lower plates. However, the central shaft also needs to be rotated when the plate is installed. After the plate is impacted, the connection will become loose. At the same time, the lack of double limit for installation reduces the installation efficiency and cannot guarantee the sealing between the two sets of plates. Therefore, a fireproof and explosion-proof plate that is easy to install is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-install fireproof and explosion-proof panel, which aims to improve the problems of existing easy-to-install fireproof and explosion-proof panels that cannot directly align and insert two sets of panels when installing them, provide dual limiting for the installation of the two sets of panels, and cannot ensure the sealing between the two sets of panels, thus reducing the installation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fireproof and explosion-proof panel that is easy to install, comprising a panel body one, a panel body two provided on the outer wall of the panel body one, a slot provided on the side wall of the panel body one, an insert block fixedly connected to the inner wall of the panel body two, a fixing magnet fixedly connected to the inner wall of the slot, a magnetic sheet magnetically connected to the outer wall of the fixing magnet, a limiting groove provided on the inner wall of the panel body one, a through hole provided through the outer wall of the insert block, a support plate fixedly connected to the inner wall of the through hole, a limiting rod slidably connected to the inner wall of the support plate, a spring fixedly connected to the surface of the limiting rod, and a sealing assembly provided on the surface of the panel body two.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the insert is adapted to the inner wall of the slot, and the side wall of the magnetic sheet is fixedly connected to the outer wall of the insert.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the limiting groove is fixedly connected to the outer wall of the limiting rod, and the end of the spring is fixedly connected to the outer wall of the support plate.

[0011] As a further description of the above technical solution:

[0012] The sealing assembly includes a mounting groove, the inner wall of which is provided with a graphite expansion strip.

[0013] As a further description of the above technical solution:

[0014] The mounting groove is located on the outer wall of the second plate near the insertion block.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the graphite expansion strip is adapted to the inner wall of the mounting groove.

[0017] As a further description of the above technical solution:

[0018] A fixing plate is fixedly connected to the inner wall of the mounting groove, and a positioning block is fixedly connected to the side wall of the fixing plate. The side wall of the positioning block has rounded corners, and the inner surface of the graphite expansion strip has a groove.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the groove is adapted to the outer wall of the positioning block, and the rounded corner is formed on the outer wall of the positioning block on the side near the fixing plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the magnetic attraction of the fixed magnet and magnetic sheet can ensure the stability of the insert block when inserted into the slot. The spring force allows the limiting rod to be inserted into the limiting groove to provide double locking for the insert block. The mounting groove and graphite expansion strip ensure the fit between the two sets of plates. The installation is completed as long as the two sets of plates are aligned and close together. This improves the installation effect and ease of installation while ensuring the sealing between the plates.

[0023] 2. In this utility model, the graphite expansion strip is fixed in the installation groove by the cooperation of the groove and the positioning block. The fixing plate provides a clamping force to the graphite expansion strip so that it faces the opening of the installation groove when it expands due to heat. The rounded corner reduces the resistance when the positioning block is connected to the groove, which facilitates the installation of the graphite expansion strip and improves the sealing effect.

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a fireproof and explosion-proof panel that is easy to install, comprising a panel body 1, a panel body 2 on the outer wall of the panel body 1, a slot 3 on the side wall of the panel body 1, and an insert 4 fixedly connected to the inner wall of the panel body 2. Two sets of slots 3 and inserts 4 are respectively provided, and are symmetrically arranged about the central axis of the panel body 1. After the insert 4 is inserted into the inner wall of the slot 3, the panel body 1 and the panel body 2 are connected. A fixing magnet 5 is fixedly connected to the inner wall of the slot 3, and a magnetic sheet 6 is magnetically connected to the outer wall of the fixing magnet 5. A limiting groove 7 is provided on the inner wall of the panel body 1 for limiting... The slot 7 is provided with four sets, and the four sets of limiting slots 7 are mirror images of each other with the central axis of the slot 3 as the axis of symmetry. The limiting slots 7 in pairs are all connected to the slot 3. The outer wall of the insert block 4 is provided with a through hole 8. The inner wall of the through hole 8 is fixedly connected with a support plate 9. The inner wall of the support plate 9 is slidably connected with a limiting rod 10. The top area of ​​the limiting rod 10 and the end away from the plate 2 are set with an incline, so as to reduce the resistance when the limiting rod 10 is inserted into the slot 3 and contacts the slot wall. The surface of the limiting rod 10 is fixedly connected with a spring 11. The surface of the plate 2 is provided with a sealing component.

[0033] Reference Figures 3-5 The outer wall of the insert 4 is adapted to the inner wall of the slot 3. The side wall of the magnetic sheet 6 is fixedly connected to the outer wall of the insert 4. The inner wall of the limiting groove 7 is fixedly connected to the outer wall of the limiting rod 10. The end of the spring 11 is fixedly connected to the outer wall of the support plate 9. The sealing assembly includes an installation groove 12. The installation groove 12 is opened on the outer wall of the plate 2 near the insert 4. The inner wall of the installation groove 12 is provided with a graphite expansion strip 13. When the graphite expands at high temperature, the interlayer compound decomposes to produce gas, causing the graphite layers to separate and expand in volume by hundreds of times. Intercalating agents such as sulfuric acid or nitric acid are inserted between the layers. At high temperature, the intercalating agent vaporizes, and the graphite layers are stretched open. The outer wall of the graphite expansion strip 13 is adapted to the inner wall of the installation groove 12.

[0034] Reference Figures 3-4A fixing plate 15 is fixedly connected to the inner wall of the mounting groove 12, and a positioning block 16 is fixedly connected to the side wall of the fixing plate 15. The side wall of the positioning block 16 is provided with a rounded corner 17. The rounded corner 17 is provided on the outer wall of the positioning block 16 near the fixing plate 15. The purpose of the rounded corner 17 is to provide a transition when the graphite expansion strip 13 is inserted into the mounting groove 12 and contacts the positioning block 16, thereby reducing resistance. A groove 14 is provided on the inner surface of the graphite expansion strip 13, and the inner wall of the groove 14 is adapted to the outer wall of the positioning block 16.

[0035] Working principle: Two sets of graphite expansion strips 13 are inserted into the two sets of mounting slots 12 respectively. When the graphite expansion strips 13 enter, they contact the positioning blocks 16. After the positioning blocks 16 are embedded in the grooves 14, they limit the graphite expansion strips 13. The fixing plate 15 and the graphite expansion strips 13 provide support and limitation. Then, the insert 4 is aligned with the slot 3 and inserted. The two pairs of limiting rods 10 are blocked by the slots 3, which causes the springs 11 to be stretched. At this time, the two pairs of limiting rods 10 are embedded in the through holes 8 respectively. When the insert 4 is completely inside the slot 3... Magnetic attraction occurs between the rear magnetic sheet 6 and the fixed magnet 5. At this time, the through hole 8 and the limiting groove 7 are aligned. After the limiting rod 10 loses contact with the wall of the groove 3, the spring 11 resets and drives the limiting rod 10 to insert into the limiting groove 7. Subsequently, sealant can be applied to the connection between plate 1 or plate 2 to complete the installation between plate 1 and plate 2. In the event of a fire, the graphite expansion strip 13 expands due to heat, which can fill the small gaps between plate 1 and plate 2, ensuring the sealing between them and thus ensuring the fireproof and explosion-proof effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
