[0002] As a new type of functional material with three-dimensional nano-porous structure, aerogel has attracted much attention due to its excellent properties such as extremely low thermal conductivity, high porosity and low density. Aerogel felt is a flexible thermal insulation material made of nano-silica as the main base material, carbon fiber, ceramic glass fiber or pre-oxidized fiber felt through special process. It has a very broad application space in the field of thermal insulation, and has been widely used in building, industrial pipeline and new energy fields.

[0003] However, when aerogel felt is applied to the thermal insulation project of indoor building, due to the existence of nano-scale pores and loose structure on the surface of aerogel felt, dust falling off may easily occur during use, which not only has adverse effects on the stability of the thermal insulation performance of the material itself, but also pollutes the indoor air. Long-term exposure of human body to such an environment may cause potential harm to the respiratory system. Therefore, a buckle type aerogel felt structure is proposed to solve the above problems.

A positioning plate 1121 is fixedly welded to the mounting bracket. An L-shaped hook 111 is slidably connected to the mounting bracket in the horizontal direction, penetrating the mounting bracket. An adjusting tube 1122 is horizontally fixedly connected to the bottom of the 11. The adjusting tube 1122 has several corrugated grooves 1123 on its outer ring. The adjusting tube 1122 is made of brittle material. Adjusting blocks 1125 are symmetrically slidably connected to the upper and lower sides of the adjusting hole 1124 on the positioning plate 1121. A first spring 1126 is connected between the adjusting block 1125 and the positioning plate 1121. The first spring 1126 is used to push the adjusting block 1125 into the corrugated groove 1123. The side facing the adjusting block 1125 is set as a semi-circular locking block 11251, and the side facing away is set as a triangular plate 11252.

Hooks 22 are fixedly set at both the upper and lower ends of the first plate 2. The hooks 22 are L-shaped and are used to hang with the hooks 111, thereby ensuring that the first plate 2 is suspended on the base wall 1.

[0031] like Figures 3-7As shown, the positioning pipe 211 penetrates the first plate 2, the positioning pipe 211 includes a leveling pipe 2111 between the first plate 2 and the base wall 1 and a guide pipe 2112 between the first plate 2 and the second plate 3, the expansion pipe 212 is fixedly connected to the end of the guide pipe 2112 away from the first plate 2, the leveling pipe 2111 is axially slidably connected with a leveling column 2113, the axial length of the leveling column 2113 is less than the length of the positioning hook, the second spring is connected between the leveling column 2113 and the positioning pipe 211, the second spring always makes the leveling column 2113 abut against the end of the adjusting pipe 1122, the screw 322 is used to drive the leveling column 2113 to slide in the positioning pipe 211 and increase the abutting force between the leveling column 2113 and the adjusting pipe 1122, in addition, the inner diameter of the interface ring of the leveling pipe 2111 is greater than the outer diameter of the interface ring of the adjusting pipe 1122.

[0032] The specific implementation process is as follows: The hook 11 drives the local first plate 2 to level by adjusting, which provides a flat wall environment for the installation of the second plate 3, when the first plate 2 is installed, the first plate 2 needs to be leveled in a large range, at this time, the first plate 2 is manually pushed and pulled to make the first plate 2 drive the adjusting pipe 1122 to slide on the positioning plate 1121, thereby leveling the first plate 2 in a large range, which can ensure the simplicity of operation and the simplicity of structure, when the adjusting pipe 1122 moves on the positioning plate 1121, the adjusting block 1125 on the positioning plate 1121 is abutted into the corrugated groove 1123 of the outer circle of the adjusting pipe 1122 under the action of the first spring 1126, since the connection between the corrugated groove 1123 and the outer wall of the adjusting pipe 1122 is smoothly arranged, therefore, the adjusting block 1125 can extrude out of the corrugated groove 1123 under the accumulation of the groove wall of the corrugated groove 1123 during the sliding process of the adjusting pipe 1122, when the next corrugated groove 1123 is aligned with the adjusting block 1125, the adjusting block 1125 is again abutted into the corrugated groove 1123 by the first spring 1126, and the above-mentioned process is repeated, thus the leveling result of the first plate 2 each time can be fixed, during the whole leveling process, the leveling pipe 2111 is sleeved on the adjusting pipe 1122, when the leveling of the first plate 2 is completed, the flatness of the first plate 2 needs to be fixed, at this time, the first plate 2 is only pressed, the first plate 2 drives the leveling pipe 2111 to move relative to the adjusting pipe 1122, the end of the leveling pipe 2111 acts with the inclined surface of the triangular plate 11252, thereby driving the adjusting block 1125 to break the groove bottom of the corrugated groove 1123, and the adjusting pipe 1122 is locked on the positioning plate 1121, which ensures that the adjusting pipe 1122 does not slide relative to the positioning plate 1121.

[0033] When the second plate 3 is installed, the screw 322 is screwed into the snap ring 32, the expansion pipe 212, the guide pipe 2112 and the leveling pipe 2111 in sequence, and the expansion pipe 212 and the guide pipe 2112 are located between the second plate 3 and the first plate 2, and the thermal insulation layer 4 is arranged between the second plate 3 and the first plate 2, the organization density of each part in the thermal insulation layer 4 is not completely the same, and when the screw 322 is screwed into the expansion pipe 212, the expansion pipe 212 will be expanded in the thermal insulation layer 4, and the expansion pipe 212 is expanded to drive the snap ring 32 to be expanded, so that the outer ring of the snap ring 32 abuts against the fixing hole 31, but when the expansion pipe 212 is not expanded symmetrically due to uneven stress in the thermal insulation layer 4, the snap ring 32 will be unsymmetrically expanded, which will cause the second plate 3 to be slightly deformed at the edge of the fixing hole 31, that is, the second plate 3 is slightly uneven at the local fixing hole 31, which is negligible, but the fundamental reason is that the local stress is uneven, and long-term uneven stress will cause the second plate 3 to be locally broken, therefore, at this time, only the screw 322 needs to be rotated, and the slight rotation of the screw 322 drives the leveling column 2113 to slide in the positioning pipe 211, and the leveling column 2113 abuts against the top end of the adjusting pipe 1122, and the adjusting pipe 1122 is locked on the positioning plate 1121, therefore, the relative sliding between the leveling column 2113 and the leveling pipe 2111 will change the angle between the hook piece 11 and the hook piece 22, and the change of the angle between the hook piece 22 and the hook piece 11 will change the local slight flatness of the first plate 2, and since the thermal insulation layer 4 between the first plate 2 and the second plate 3 is compressed, the slight flatness change of the first plate 2 will be transmitted to the second plate 3, so that the local stress of the second plate 3 is uniform, the local unevenness is leveled, and the local breakage of the second plate 3 is prevented The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, some modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the patent.
