[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Example 1

[0031] Aerogels possess excellent thermal insulation properties, but they are prone to breakage under external pressure, which not only reduces their insulation effectiveness but also limits their applications. This embodiment provides an aerogel thermal insulation sheet, such as... Figures 1-5 As shown, it includes an aerogel block 1 with through holes 4 on it. The through holes 4 are located at the edges of the aerogel block 1, with at least two sets of through holes 4 at the diagonal corners. Here, four through holes 4 are arranged at the four corners. A top plate 2 and a bottom plate 3 are respectively provided at the top and bottom of the aerogel block 1. The top plate 2 and the bottom plate 3 can be ceramic plates, rock wool plates, and rubber plates. These materials have good heat insulation effects to ensure the overall heat insulation performance of the aerogel heat insulation sheet.

[0032] Although the setting of the top plate 2 and the bottom plate 3 plays a certain protective role for the aerogel block 1, and plays a protective function when facing impact or collision, since the top plate 2 and the bottom plate 3 are directly in contact with the aerogel block 1, when the top plate 2 or the bottom plate 3 is pressed, the aerogel block 1 is also easy to be crushed or cracked. Therefore, the cylindrical stick body 5 is fixed on the top plate 2, and the stick slot 6 is opened on the bottom plate 3, and the stick slot 6 and the through hole 4 are matched with each other. When the stick body 5 passes through the through hole 4 and is combined with the stick slot 6, the aerogel block 1 is clamped between the top plate 2 and the bottom plate 3; so that the top surface and the bottom surface of the aerogel block 1 are in contact with the top plate 2 and the bottom plate 3 respectively. Even if the top plate 2 and the bottom plate 3 are pressed, the top plate 2 and the bottom plate 3 will not excessively press the aerogel block 1 under the support of the stick body 5, effectively avoiding the damage of the aerogel block 1, and ensuring the heat insulation performance and service life of the aerogel heat insulation sheet.

[0033] The edges of the above-mentioned top plate 2, aerogel block 1 and bottom plate 3 are provided with a wrapping part 7 which tightly stacks the three. The wrapping part 7 is made of insulating tape. In specific assembly, the aerogel block 1 is first stacked on the bottom plate 3, the stick body 5 on the bottom plate 3 passes through the corresponding through hole 4, then the stick slot 6 of the top plate 2 is aligned with the stick body 5 and is pressed down, so that the stick body 5 is combined with the stick slot 6, then the insulating tape is wound on the edges to form the wrapping part 7, which can well make the top plate 2, aerogel block 1 and bottom plate 3 tightly combined, preventing the top plate 2 and the bottom plate 3 from falling off the aerogel block 1.

[0034] In addition, the end edge of the stick slot 6 away from the bottom plate 3 is provided with an arc part 8, which facilitates the top of the stick body 5 to quickly enter the stick slot 6.

[0035] Example 2

[0036] The same as example 1, as shown in Figure 6 , the difference is that the stick body 5 is a rectangular body, and the stick slot 6 and the through hole 4 are matched with each other.

[0037] Example 3

[0038] The same as example 1, as shown in Figure 7 , the difference is that the stick body 5 is a hexagonal body, and the stick slot 6 and the through hole 4 are matched with each other.

[0039] Example 4

[0040] Based on example 1, as shown in Figures 8-9As shown, the elastic ring 9 is fixed on the upper part of the cutting body 5, and the limiting groove 10 in the shape of a ring is arranged on the inner wall of the cutting groove 6, after the elastic ring 9 enters the limiting groove 10, the top plate 2 and the bottom plate 3 are clamped with each other, the clamping of the two improves the combination performance of the cutting groove 6 and the cutting body 5, effectively avoids the separation of the top plate 2 and the bottom plate 3, and helps the staff to smoothly, quickly and conveniently perform the edge coating treatment by using the insulating tape.

[0041] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
