[0002] External wall insulation boards are building insulation products that replace traditional putty layers. During installation, they are pasted on the outer wall of the target wall. The construction is simple and they are particularly suitable for secondary decoration and maintenance of buildings. However, in the existing technology, most of the external insulation boards do not have relevant connection mechanisms between the individual units. Not only can the wall insulation boards not be formed into a whole to improve the stability of the insulation boards, but there will also be gaps between the two individual insulation boards, which will cause heat from inside and outside the building to be exchanged in the gap between the two insulation boards, resulting in reduced insulation performance. Utility Model Content

[0003] The purpose of the utility model is to provide an external wall insulation board, which can connect the individual insulation boards on the wall to form a whole, thereby improving the stability of the insulation board and sealing the gaps between the insulation boards to improve the insulation performance.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] An external wall insulation panel comprises a base plate and an outer panel, wherein an insulation layer is bonded and fixed between the base plate and the outer panel, a sealing groove 1 is formed on the upper surface and right side surface of the outer panel, an installation cavity is formed inside the outer panel and the installation cavity is connected to the left and lower side surfaces of the outer panel, and two sealing plates 2 are sleeved in the installation cavity and correspond to the two sealing grooves 1 respectively;

[0006] Sealing grooves 2 are provided at three corners of the front side of the outer guard plate, and a sealing plate 1 is fixedly provided at another corner of the front side of the outer guard plate.

[0007] The side surfaces of the two sealing plates are respectively fixedly connected to one end of the two connecting plates, and the other ends of the two connecting plates are each provided with a threaded hole.

[0008] The two threaded holes are respectively threadedly connected to the opposite ends of the two screw rods, and the optical axes of the two screw rods are respectively rotatably connected to the front ends of the two fixing plates through rolling bearings.

[0010] The two bevel gears 1 are both meshed and connected with the same bevel gear 2. The bevel gear 2 is fixedly arranged on the rear side of the rotating shaft. The rear end of the rotating shaft is rotatably connected to the rear side surface of the installation cavity through a rolling bearing.

[0011] The front side of the rotating shaft is rotatably connected to the countersunk hole opened on the front side of the outer guard plate through a rolling bearing. The front end of the rotating shaft is provided with a straight groove, and a sealing cover is sleeved in the countersunk hole.

[0012] The rear side surface of the base plate is provided with a striped protrusion, and the bottom end of the sealing groove 1 on the right side is connected with the bottom surface of the outer guard plate.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, an external wall insulation board includes a base plate 1 and an outer protective plate 3. An insulation layer 2 is bonded and fixed between the base plate 1 and the outer protective plate 3. A sealing groove 4 is formed on the upper surface and right side of the outer protective plate 3. An installation cavity 9 is formed inside the outer protective plate 3 and is in communication with the left and lower side surfaces of the outer protective plate 3. Two sealing plates 7 are sleeved in the installation cavity 9, corresponding to the two sealing grooves 4 respectively.

[0024] Sealing grooves 2 5 are provided at three corners of the front side of the outer guard plate 3, and a sealing plate 1 6 is fixedly provided at another corner of the front side of the outer guard plate 3. Since sealing grooves 2 5 and sealing plates 1 6 are respectively provided at the four corners of the outer guard plate 3, when installing the present insulation board, the user sticks the base plate 1 on the outer wall surface, and sticks multiple insulation boards together so that the sealing plate 1 6 is stuck in the sealing grooves 2 5 opened on the three adjacent outer guard plates 3, and the relative corners of the four adjacent insulation boards are sealed by the sticking of the sealing plate 1 6 and the sealing groove 2 5.

[0025] Furthermore, the side surfaces of the two sealing plates 7 are fixedly connected to one end of the two connecting plates 8 respectively, and the other ends of the two connecting plates 8 are each provided with a threaded hole 10.

[0026] Furthermore, the two threaded holes 10 are respectively threadedly connected to the opposite ends of the two screw rods 11, and the optical axes of the two screw rods 11 are respectively rotatably connected to the front ends of the two fixing plates 12 through rolling bearings.

[0027] Furthermore, the rear ends of the two fixing plates 12 are fixedly connected to the rear side surface of the installation cavity 9, and the opposite ends of the two screw rods 11 are fixedly connected to the two bevel gears 16 respectively.

[0028] Furthermore, the two bevel gears 16 are meshed with the same bevel gear 2 17. The bevel gear 2 17 is fixedly arranged on the rear side of the rotating shaft 18. The rear end of the rotating shaft 18 is rotatably connected to the rear side of the installation cavity 9 through a rolling bearing. After the insulation board is pasted on the outer wall, the rotating shaft 18 can be rotated clockwise using the straight groove 14 with the help of a tool. At this time, the rotating shaft 18 drives the two screws 11 to rotate forward through the bevel gear 16 and the bevel gear 2 17. When the screw 11 rotates forward, it drives the two sealing plates 2 7 to move to the outside of the installation cavity 9 through the threaded hole 10 and enter the sealing groove 1 4 opened in the adjacent outer guard plate 3. The gaps between the adjacent insulation boards are closed by the cooperation of the sealing plate 1 6 and the sealing groove 2 5, and the sealing plate 2 7 and the sealing groove 1 4, so that the single insulation boards are connected to each other to form a whole, thereby improving the stability of the insulation board and sealing the gaps between the insulation boards to ensure the thermal insulation of the insulation board.

[0029] Furthermore, the front side of the rotating shaft 18 is rotatably connected to the countersunk hole 15 opened on the front side of the outer guard plate 3 through a rolling bearing. A straight groove 14 is opened at the front end of the rotating shaft 18, and a sealing cover 13 is provided in the countersunk hole 15. By providing the sealing cover 13 in the countersunk hole 15, the sealing cover 13 is used to seal the countersunk hole 15 to ensure the integrity of the outer guard plate 3 and improve the overall aesthetics of the insulation board.

[0030] Furthermore, striped protrusions are provided on the rear side of the substrate 1. By providing striped protrusions on the rear side of the substrate 1, the striped protrusions can be used to increase the bonding area between the adhesive material and the substrate 1 when the substrate 1 is pasted on the exterior wall, thereby improving the bonding strength of the substrate 1. The bottom end of the right sealing groove 4 is connected to the bottom surface of the outer guard plate 3.

[0031] The working principle of the present invention is as follows: when installing the insulation board, the user sticks and fixes the base plate 1 on the outer wall surface, and sticks the multiple insulation boards together so that the sealing plate 16 fits in the sealing groove 2 5 opened on the three adjacent outer protective plates 3, and the relative corners of the four adjacent insulation boards are sealed by the fit between the sealing plate 16 and the sealing groove 2 5, and the rotating shaft 18 can be rotated clockwise with the help of a tool using the straight groove 14. At this time, the rotating shaft 18 drives the two screws 11 to rotate forward through the bevel gear 16 and the bevel gear 2 17. When the screw 11 rotates forward, it drives the two sealing plates 2 7 to move to the outside of the installation cavity 9 through the threaded hole 10 and enter the sealing groove 1 4 opened on the adjacent outer protective plates 3. The gaps between the adjacent insulation boards are sealed by the cooperation between the sealing plate 16 and the sealing groove 2 5, and the sealing plate 2 7 and the sealing groove 1 4, and then the sealing cover 13 is inserted into the countersunk hole 15 to seal the countersunk hole 15.

[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
