[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-4 A fire door core panel includes a first connecting plate 1, which has two connecting grooves 8, and the two connecting grooves 8 can be respectively inserted with connecting edges 5, and the two connecting edges 5 are fixedly connected to the abutment plates 4. A plurality of second connecting plates 2 are arranged between the abutment plates 4 and the first connecting plate 1. The plurality of second connecting plates 2 are limited by a limiting mechanism, and the connecting edges 5 are fixed by a fixing mechanism. By changing the number of the second connecting plates 2, the size of the core panel can be adjusted, so that the inner frames of fire doors of different sizes can be assembled, thereby improving the applicability of the fire door core panel.

[0020] The limiting mechanism includes a limiting groove 6, which is opened on the first connecting plate 1. The lower end of the second connecting plate 2 is fixedly connected to a limiting block 7, which can be inserted into the limiting groove 6. By using the limiting block 7 in conjunction with the limiting groove 6, the plate materials play a role of lateral limitation, which is beneficial to the connection effect between the plate materials.

[0021] The fixing mechanism includes a mounting hole 14, which is provided on the first connecting plate 1, and the mounting hole 14 is connected to the connecting groove 8. A spring 13 is provided in the mounting hole 14, and a fixing column 12 is fixedly connected to the spring 13. A plurality of fixing grooves 9 are provided on the connecting rib 5, and a first inclined surface 10 is provided in the fixing groove 9. When the connecting rib 5 moves downward, the connecting rib 5 abuts against the first inclined surface 10, so that the spring 13 is gradually compressed, ensuring that the connecting rib 5 can move downward. A rectangular groove is provided on the second connecting plate 2, and the connecting rib 5 passes through the rectangular groove and penetrates the second connecting plate 2. By inserting the connecting rib 5 into the connecting groove 8, the fixing column 12 enters the fixing groove 9 under the action of the restoring force of the spring 13, which will fix the connecting rib 5, so that the abutting plate 4 abuts against the second connecting plate 2, and the second connecting plate 2 is clamped and fixed.

[0022] A second inclined surface 15 is provided at the lower end of the connecting rib 5 , and the second inclined surface 15 facilitates inserting the connecting rib 5 into the connecting groove 8 .

[0023] During installation, the connecting rib 5 is passed through the second connecting plate 2 so that the abutting plate 4 abuts against the second connecting plate 2 at the upper end, and then the connecting rib 5 is inserted into the connecting groove 8. When the second connecting plate 2 is clamped and fixed, the fixing column 12 enters the fixing groove 9 under the action of the restoring force of the spring 13, which will fix the connecting rib 5.

[0024] Example 2: In Example 1, after installation, due to the limitation of the fixing column 12, the connecting edge 5 cannot be pulled out, which makes it inconvenient to disassemble the core plate. Figure 4 As another preferred embodiment of the present invention, on the basis of embodiment 1, a placement groove 3 is opened on the first connecting plate 1, and the placement groove 3 is connected to the mounting hole 14. A support block 11 is fixedly connected to the placement groove 3 by bolts, and the support block 11 is fixedly connected to the spring 13. By loosening the bolts, the support block 11 is removed, and the spring 13 is pulled to move, so that the fixing column 12 is disengaged from the fixing groove 9, and the fixed limit of the connecting edge 5 is released, so that the core plate can be disassembled.

[0025] Example 3: Reference Figure 1-3As another preferred embodiment of the present invention, on the basis of embodiment 1, a sealing layer is provided on the upper and lower surfaces of several second connecting plates 2, the upper surface of the first connecting plate 1, and the lower surface of the abutting plate 4. The sealing layer is a fireproof sealant layer, which seals the gaps between the plates to prevent smoke from entering through the gaps.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
