[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-5 As shown, a composite fireproof heat-insulating board comprises a body 1;

[0027] The connecting member 2 is arranged on the body 1, and includes an arc-shaped plate 21 and an obliquely arranged abutment portion 23, a hook tongue 22 is fixedly arranged on the outer wall of the abutment portion 23, and the abutment portion 23 is driven to deflect and bend the arc-shaped plate 21;

[0028] A slot 4 is provided on the body 1 and is plugged into and matched with the hook tongue 22;

[0029] The bentonite waterproof blanket 5 mounted on the inner wall of the abutment portion 23 is pushed outward by the arc-shaped plate 21;

[0030] The connecting member 2 and the slot 4 are respectively arranged on two sides of the body 1, and both sides of the body 1 are inclined surfaces.

[0031] Specifically, wedge blocks and plug-in grooves are respectively provided on both sides of the body 1. When assembling multiple bodies 1, the wedge blocks and the plug-in grooves correspond to each other, and a rectangular groove for accommodating the connecting piece 2 is opened on the body 1. When assembling, the first body 1 is fixed to the wall so that the bentonite waterproof blanket 5 is close to the outer side of the wall, and then the second body 1 is slidably plugged into the plug-in groove through the wedge block. During the sliding process, the connecting piece 2 on the first body 1 is gradually located in the rectangular groove of the second body 1, and the inner wall of the rectangular groove contacts and pushes the contact part 23, so that the contact part 23 is deflected from the inclined state to the vertical state tightly attached to the inner wall of the rectangular groove. At the same time, the arc plate 21 is squeezed and bent. Since the inner wall of the arc plate 21 is provided with an arc-shaped notch, The arc plate 21 is made to bend more easily in the direction close to the bentonite waterproof blanket 5. During the bending process, the arc plate 21 pushes the bentonite waterproof blanket 5 to bulge outward. At this time, the protruding body 1 of the bentonite waterproof blanket 5 is in close contact with the wall. When the wall is damp or water seepage occurs, the bentonite waterproof blanket 5 absorbs water, and the bentonite waterproof blanket 5 expands after absorbing water and forms a gel-like waterproof layer, which protects and reinforces the joints of the two bodies 1, and prevents the body 1 from warping due to moisture. The expanded bentonite waterproof blanket 5 further abuts the abutment portion 23 against the rectangular groove; at the same time, the abutment portion 23 drives the hook tongue 22 to move during the deflection process, and makes the hook tongue 22 and the card slot 4 plugged and fixed to each other, so that the first body 1 and the second body 1 are fixed.

[0032] In the above technology, during the assembly process of different main bodies 1, the abutment portion 23 is deflected from an inclined state to a vertical state closely attached to the inner wall of the rectangular groove, so that the hook tongue 22 is plugged and assembled with the card slot 4, and at the same time, the arc plate 21 presses the bentonite waterproof blanket 5 against the wall. When the wall is damp or water seepage occurs, the bentonite waterproof blanket 5 absorbs water, and the bentonite waterproof blanket 5 expands after absorbing water to form a gel-like waterproof layer, which protects and reinforces the joints of the two main bodies 1, preventing the main body 1 from warping due to moisture, and the expanded bentonite waterproof blanket 5 further presses the abutment portion 23 against the rectangular groove to strengthen the connection between different main bodies 1.

[0033] As an embodiment further provided by the present invention, a rotating member 41 is rotatably disposed in the slot 4 , and an opening engaged with the hook tongue 22 is formed on the rotating member 41 .

[0034] Specifically, when the abutment portion 23 is deflected from an inclined state to a vertical state in close contact with the inner wall of the rectangular groove, the hook tongue 22 is inserted into the slot 4 and rotates along the slot 4. A protrusion is provided at the end of the hook tongue 22, which engages with the opening, so that the rotating member 41 rotates forward by a certain angle. The elastic member 43 on the rotating member 41 rotates forward with the rotating member 41 and is not blocked by the locking teeth 42. When the hook tongue 22 is pulled, the hook tongue 22 drives the rotating member 41 to rotate in the opposite direction. At this time, the elastic member 43 is blocked by the locking teeth 42 so that the hook tongue 22 will not be separated from the rotating member 41.

[0035] As another embodiment further provided by the present invention, the arc plate 21 is in a bent state and encloses an air passage with the inner wall of the body 1 .

[0036] Specifically, the arc plate 21 is driven to bend in the direction close to the bentonite waterproof blanket 5. At this time, a gap is generated between the arc plate 21 and the inner wall of the main body 1, which is convenient for air circulation. The air further dries the seam, and the air channel is connected to the bentonite waterproof blanket 5 through the through hole, so that the moisture in the air is dried by the bentonite waterproof blanket 5, thereby ensuring the dryness of the air channel.

[0037] As another embodiment further provided by the present invention, both ends of the air passage are connected with ventilation holes 3, the ventilation holes 3 are arranged through the main body 1, and both ends of the ventilation holes 3 are stepped structures with decreasing inner diameters.

[0038] Specifically, the air passage and the vent 3 are vertically connected passages, and the inner wall of the vent 3 is provided with an anti-corrosion coating. Both ends of the vent 3 are stepped structures with decreasing inner diameters, so that after the airflow in the air passage enters the vent 3, the inner wall of the vent 3 narrows, which accelerates the airflow speed until it passes through the other end of the vent 3, thereby improving the ventilation efficiency.

[0039] Working principle: wedge blocks and plug-in slots are respectively provided on both sides of the body 1. When assembling multiple bodies 1, the wedge blocks and the plug-in slots correspond to each other, and a rectangular slot for accommodating the connector 2 is opened on the body 1. When assembling, the first body 1 is fixed on the wall so that the bentonite waterproof blanket 5 is close to the outside of the wall, and then the second body 1 is slidably plugged into the plug-in slot through the wedge blocks. During the sliding process, the connector 2 on the first body 1 is gradually located in the rectangular slot of the second body 1, and the inner wall of the rectangular slot contacts and pushes the abutment portion 23. , so that the abutment portion 23 is deflected from the inclined state to a vertical state close to the inner wall of the rectangular groove, the hook tongue 22 is inserted into the card slot 4, and rotates along the card slot 4, and the end of the hook tongue 22 is provided with a protrusion, which is engaged with the opening, so that the rotating member 41 rotates forwardly by a certain angle, and the elastic member 43 on the rotating member 41 rotates forward with the rotating member 41 and is not blocked by the clamping teeth 42. When the hook tongue 22 is pulled, the hook tongue 22 drives the rotating member 41 to rotate in the opposite direction. At this time, the elastic member 43 is blocked by the clamping teeth 42 so that the hook tongue 22 will not be separated from the rotating member 41 The curved plate 21 is separated from the wall, and the curved plate 21 is pushed and bent. Since the inner wall of the curved plate 21 is provided with an arc-shaped notch, the curved plate 21 is easier to bend in the direction close to the bentonite waterproof blanket 5. During the bending process, the curved plate 21 pushes the bentonite waterproof blanket 5 to bulge outward. At this time, the protruding body 1 of the bentonite waterproof blanket 5 is in close contact with the wall. When the wall is damp or water seepage occurs, water is absorbed through the bentonite waterproof blanket 5, and the bentonite waterproof blanket 5 expands after absorbing water and forms a gel-like waterproof layer, which protects and reinforces the joints of the two bodies 1, thereby preventing the body 1 from being damaged. The edges are warped due to moisture, and the expanded bentonite waterproof blanket 5 further abuts the abutting portion 23 against the rectangular groove; a gap is created between the bent arc plate 21 and the inner wall of the main body 1 to facilitate air circulation, and the seams are further dried by air, and the air passage is connected to the bentonite waterproof blanket 5 through the through hole, so that the moisture in the air is dried by the bentonite waterproof blanket 5, thereby ensuring the dryness of the air passage. After the wind flow enters the vent 3, the inner wall of the vent 3 is narrowed, which accelerates the wind flow until it passes through the other end of the vent 3, thereby improving the ventilation efficiency.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that 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.
