[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] See Figures 1 to 12As shown in the figure, a composite exterior wall insulation board includes a wall-adjacent board 1, a mounting board 2, and a locking mechanism 3. A plurality of corrugations 11 are provided on one side of the wall-adjacent board 1. The side of the wall-adjacent board 1 away from the corrugations 11 and the mounting board 2 are connected to each other by a plurality of connecting rods 12. A rock wool board 13 is also provided between the wall-adjacent board 1 and the mounting board 2. Two mounting grooves 21 are mirror-symmetrically arranged on the outer walls on both sides of the mounting board 2. The two mounting grooves 21 on the same side are respectively located at both ends of the corresponding side. A locking mechanism 3 for fixing to the adjacent mounting board 2 is provided in each mounting groove 21. Each set of locking mechanisms 3 includes a sliding plate 31, a return spring 32, and a positioning post 33. Oblique chutes 211 are provided on the inner walls on both sides of each mounting groove 21. Square blocks 311 that cooperate with the oblique chutes 211 are provided on both sides of each sliding plate 31 along the length direction. The square blocks 311 are slidably arranged in the corresponding oblique chutes 211. The return spring 32 is provided between the corresponding sliding plate 31 and the inner wall of the mounting groove 21. Telescopic grooves 22 that cooperate with the mounting grooves 21 are provided on the two sides of the mounting board 2 adjacent to the mounting grooves 21. A pressing block 23 is slidably arranged in each telescopic groove 22. A rectangular groove 231 is provided on each pressing block 23. A clamping block 232 is slidably arranged in each rectangular groove 231. A clamping groove 312 that cooperates with the clamping block 232 is provided on each sliding plate 31. A plurality of through holes 24 communicating with the corresponding mounting grooves 21 are also provided on each mounting board 2. The positioning post 33 is slidably arranged in the corresponding through hole 24. A positioning hole 233 that cooperates with the positioning post 33 is provided on each pressing block 23.

[0043] By providing the corrugations 11, it is ensured that the adhesive can be stably adhered to the wall-adjacent board 1, thereby improving the connection stability between the wall-adjacent board 1 and the exterior wall. Under the action of the elastic force of reset, the sliding plate 31 can extend out of the corresponding mounting groove 21 along the oblique chute 211. When installing the next wall-adjacent board 1, the staff only needs to press the mounting board 2. Subsequently, through the pressing block 23 provided in the telescopic groove 22 contacting the corresponding sliding plate 31, the clamping block 232 on the pressing block 23 can extend into the clamping groove 312 of the corresponding sliding plate 31. At this time, as the wall-adjacent board 1 moves towards the exterior wall, the pressing block 23 can move synchronously with the corresponding sliding plate 31 along the oblique chute 211, so that the two adjacent wall-adjacent boards 1 are mutually attached. At this time, the pressing block 23 can be synchronously retracted into the corresponding mounting groove 21 with the sliding plate 31. Subsequently, by adjusting the positioning post 33, the positioning post 33 is extended into the positioning hole 233 of the pressing block 23, so as to quickly complete the fixation of the mounting board 2. And multiple insulation boards can be sequentially connected to each other, thereby improving the overall stability.

[0044] See Figures 9 to 12As shown, at one end of each positioning post 33 extending into the corresponding installation groove 21, there is an installation disc 331. A pressing spring 332 is also sleeved on each positioning post 33. The pressing spring 332 is located between the corresponding mounting plate 2 and the inner wall of the installation groove 21. At one end of each pressing block 23 away from the corresponding mounting plate 2, there is a triangular guiding portion 234 that cooperates with the positioning post 33. At one end of each positioning post 33 away from the installation disc 331, there is a limiting disc 333. A pulling ring 334 is provided on each limiting disc 333; on the mounting plate 2, there are a plurality of rotating holes 25 communicating with the telescopic groove 22. A rotating rod 251 is rotatably arranged in each rotating hole 25. At the bottom inner wall of each rectangular groove 231, there is a traction hole 235. On one side of each clamping block 232 close to the bottom inner wall of the rectangular groove 231, there is a traction rope 236. One end of the traction rope 236 away from the clamping block 232 passes through the traction hole 235 and is wound around the corresponding rotating rod 251; a pressing spring 237 is also sleeved on the traction rope 236. The pressing spring 237 is located between the corresponding clamping block 232 and the bottom inner wall of the rectangular groove 231. A pushing spring 238 is also provided between each pressing block 23 and the bottom inner wall of the corresponding telescopic groove 22.

[0045] By providing the limiting disc 333, the distance of the positioning post 33 can be restricted. During the process of pressing the mounting plate 2, under the elastic force of the pushing spring 238 and the pressing spring 237, the pressing block 23 extends into the telescopic groove 22, the traction rope 236 is in a taut state, the clamping block 232 extends out of the rectangular groove 231, and the triangular guiding portion 234 on the pressing block 23 can come into contact with the end of the positioning post 33 first, so that the positioning post 33 moves toward the direction close to the limiting disc 333 against the elastic force of the corresponding pressing spring 332. At this time, the end of the positioning post 33 abuts against the surface of the pressing block 23, so that the gap between the two mounting plates 2 is reduced. When the two mounting plates 2 are in contact with each other, the positioning post 33 can extend into the positioning hole 233 under the elastic force of the pressing spring 332, thus completing the fixation between the positioning block and the sliding plate 31; when it is necessary to take out the wall attachment plate 1, by adjusting the rotating rod 251, the traction rope 236 is pulled, so that the clamping block 232 retracts into the rectangular groove 231 against the elastic force of the pressing spring 237. At this time, the clamping block 232 and the pressing block 23 are in an "integrated" state. Subsequently, by pulling the positioning post 33 through the pulling ring, the positioning post 33 is separated from the pressing block 23. Then, by continuously adjusting the rotating rod 251, the pressing block 23 can be retracted into the telescopic groove 22. At this time, the mounting plate 2 is in an unlocked state, and the staff can remove the mounting plate 2, which is convenient for the staff to maintain the insulation board at any position.

[0046] See Figure 11 As shown, on each pressing block 23, there is a strip-shaped accommodating groove 239 for accommodating the traction rope 236. The strip-shaped accommodating groove 239 communicates with the corresponding traction hole 235.

[0047] By providing a strip-shaped accommodation groove 239, the traction rope 236 can be guided, preventing the traction rope 236 from jamming and causing the pressing block 23 to be unable to move.

[0048] See Figures 4 to 8 As shown, at the center of the side of each mounting plate 2 close to the wall plate 1, a square groove 26 is provided. A partition plate 27 is arranged in the square groove 26. Piston plates 28 are arranged on both sides of each partition plate 27. A plurality of fixing rods 281 distributed in a rectangle are connected to each other between the two piston plates 28. A phase change material 282 is filled between the two piston plates 28. Fixing holes 271 for accommodating the fixing rods 281 are arranged in a rectangle on the partition plate 27. The fixing rods 281 are slidably arranged in the fixing holes 271. Memory metal springs 283 are sleeved at both ends of the fixing rods 281, and the two memory metal springs 283 are respectively located on both sides of the partition plate 27.

[0049] To further improve the heat insulation effect of the outer wall, two piston plates 28 are arranged in the square groove 26 of the mounting plate 2, and a phase change material 282 is filled between the two piston plates 28. In the initial state, under the action of the two memory metal springs 283, the piston plate 28 close to the inner wall of the bottom of the square groove 26 fits against the inner wall of the bottom of the square groove 26. When the temperature rises, the phase change material 282 stores heat, and the memory metal springs 283 at both ends of the fixing rods 281 move with the increase in the temperature of the phase change material 282, causing the two piston plates 28 to move away from the square groove 26. At this time, a gap is generated between the corresponding piston plate 28 and the inner wall of the bottom of the corresponding square groove 26, forming a "negative pressure" state, which can isolate the phase change material 282 and reduce the transfer of internal and external temperatures, improving the heat insulation effect. At this time, the phase change material 282 can be squeezed as much as possible between the partition plate 27 and the piston plate 28 on the side away from the square groove 26. At night, the energy-storing phase change material 282 can continuously dissipate heat, ensuring the stability of the outer wall temperature.

[0050] See Figure 7 As shown, at the center of each side of the side of the mounting plate 2 away from the square groove 26, a strip-shaped air intake groove 29 is provided, and each strip-shaped air intake groove 29 is communicated with the corresponding square groove 26 through a strip-shaped heat dissipation groove 291.

[0051] In order to improve the heat dissipation effect of the exterior wall under high temperature conditions; a strip air inlet groove 29 is provided, and the strip air inlet groove 29 is connected to the corresponding square groove 26 through the square heat dissipation groove. In the case of wind, the gas can enter along the strip air inlet groove 29 to circulate between the corresponding piston plate 28 and the rock wool board 13, thereby avoiding the temperature of the rock wool board 13 from being too high; secondly, when the heat reserve of the phase change material 282 is completed, the piston plate 28 near the strip air inlet groove 29 can move, thereby blocking the strip air inlet groove 29, thereby avoiding gas circulation, causing the temperature of the phase change material 282 reserve to drop, and ensuring the stability of the overall temperature.

[0052] See also Figure 7 As shown, the partition plate 27 is also provided with a flow groove 272 for the phase change material 282 to flow.

[0053] By providing a circulation groove 272, the phase change material 282 can be circulated, which can not only make the phase change material 282 on both sides of the partition plate 27 evenly mixed to ensure temperature consistency; but also can make as much phase change material 282 as possible move toward the direction close to the rock wool board 13 when the memory metal spring 283 is deformed due to temperature increase, thereby reducing the temperature loss of the phase change material 282 and increasing the insulation time.

[0054] See also Figures 5 to 6 As shown, each piston plate 28 away from the square groove 26 is also coated with thermal conductive silicone grease 284.

[0055] By applying the thermal conductive silicone grease 284 , the temperature of the phase change material 282 can be better transferred, thereby improving the heat preservation effect.

[0056] A production process of a composite exterior wall insulation board in the present invention comprises the following steps:

[0057] S1: Slot and make holes on the mounting plate 2, and install the partition plate 27, the piston plate 28, the sliding plate 31 and the lower pressing block 23 to the designated slots through the corresponding accessories, and perform corresponding debugging to ensure the smoothness of the activities between the various parts;

[0058] S2: injecting a certain amount of liquid phase change material 282 between the two piston plates 28;

[0059] S3: Apply thermal conductive silicone grease 284 to the external piston plate 28 and install connecting rods 12 at the four corners;

[0060] S4: cutting the rock wool board 13 into corresponding sizes, and passing the connecting rod 12 through the rock wool board 13 for fixing;

[0061] S5: The end of the connecting rod 12 is engaged with the clamp on the wall plate 1 through a buckle, thereby completing the entire installation.

[0062] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
