The installation of multiple hooks 11 facilitates the storage and use of parts.

[0040] Specifically, firstly, a functional unit is installed on the front side of the original wall 1 of the old house. By installing the insulation layer 4, the heat exchange between the inside and outside of the building is effectively reduced, and the loss of indoor heat is reduced. This keeps the indoor temperature warm in winter and blocks the intrusion of external heat in summer, thereby reducing energy consumption and achieving energy-saving effects. Next, the rear concrete decorative base layer 5 is installed to provide a fixed foundation for the insulation layer 4, ensuring that the insulation layer 4 will not shift or fall off during use. In addition, by installing the flame-retardant and fireproof layer 6, its flame-retardant or non-combustible properties can delay the spread of fire in the event of a fire and prevent flames and heat from spreading to other areas, buying valuable time for personnel evacuation and fire rescue. Furthermore, through the installation of the front concrete decorative base layer 3, since it directly affects the appearance of the building, its surface can be plastered, tiled, or painted to adapt to different architectural styles and decorative needs, making the building more beautiful and elegant. Through the above procedures, the use of nails or glue can be avoided, protecting the integrity of the original wall 1 of the old house. The modular installation supports partial replacement, which can reduce maintenance costs.

[0041] Reference Figure 1 , Figure 3 and Figure 5The connecting mechanism 2 includes two mounting blocks 204, which are fixedly connected to the left and right ends of the front concrete decorative substrate 3, respectively. Sliding grooves 205 are provided on the upper and lower ends of adjacent sides of the two mounting blocks 204. Push plates 201 are slidably connected to adjacent sides of the two sliding grooves 205. Threaded rods 202 are threadedly connected to the upper and lower ends of the two push plates 201. Connecting circular plates 203 are fixedly connected to the front sides of the two threaded rods 202. Connecting bent rods 207 are rotatably connected to the front sides of the connecting circular plates 203. The middle of the two connecting bent rods 207... A connecting rod 206 is fixedly connected. The adjacent sides of the two mounting blocks 204 are slidably connected to the left and right sides of the decorative wall panel 7, respectively. Protective sleeves 14 are installed on the outer sides of the two connecting bent rods 207. The installation of protective sleeves 14 reduces the probability of damage to the connecting bent rods 207. Anti-slip sleeves 8 are installed on the middle of the outer side of the connecting rod 206. The installation of anti-slip sleeves 8 reduces the probability of accidents during operation. Limiting plates 9 are fixedly connected to the front sides of the two mounting blocks 204. The installation of limiting plates 9 prevents the pushing plate 201 from moving excessively.

[0042] Specifically, firstly, two mounting blocks 204 are fixed to the front side of the front concrete decorative substrate 3. When installing the decorative wall panel 7, first align its left and right sides with the side adjacent to the mounting blocks 204. Then, by operating the connecting rod 206, the two connecting bent rods 207 are rotated. The rotation of the two connecting bent rods 207 causes multiple connecting round plates 203 to rotate synchronously, which in turn causes multiple threaded rods 202 to rotate synchronously. Since the threaded rods 202 are threadedly connected to the push plate 201, the push plate 201 slides in the sliding groove 205, gradually pushing the decorative wall panel 7 to the installation position and fixing it. Since all the threaded rods 202 rotate synchronously, it ensures that the decorative wall panel 7 can move stably and avoids the situation of local installation instability.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The decorative wall panel 7 has a bolt 13 threadedly connected to the bottom right end of the front side, and a label 12 is fixedly connected to the outside of the bolt 13;

[0044] Specifically, the installation of bolt 13 facilitates the replacement of label 12, and the installation of label 12 facilitates the prompting of users.

[0045] Working principle: First, functional units are installed on the front side of the original wall 1 of the old house. The installation of the insulation layer 4 reduces the transfer of heat between the inside and outside of the building, reduces the loss of indoor heat, keeps the indoor temperature warm in winter, and blocks outdoor heat from entering the indoor in summer, thereby reducing energy consumption and achieving energy saving. The installation of the concrete decorative base layer 5 provides a reliable fixed foundation for the insulation layer 4, ensuring that there will be no displacement or falling off during use. The installation of the flame-retardant and fireproof layer 6, due to its flame-retardant or non-combustible properties, can slow down the spread of fire in the event of a fire, prevent the spread of flames and heat to other parts, and buy time for personnel evacuation and fire rescue. The installation of the front concrete decorative base layer 3 directly affects the appearance of the building. Its surface can be treated in various ways, such as plastering, tiling, and painting, to meet different architectural styles and decoration requirements, making the building more beautiful and elegant. Through the above process, the use of nails or glue can be avoided, protecting the integrity of the original wall 1 of the old house. The modular design supports partial replacement and reduces maintenance costs.

[0046] First, fix two mounting blocks 204 to the front side of the front concrete decorative substrate 3. When installing the decorative wall panel 7, first align its left and right sides with the adjacent side of the mounting blocks 204. Then, drive the two connecting bent rods 207 to rotate by operating the connecting rod 206. The rotation of the two connecting bent rods 207 causes multiple connecting round plates 203 to rotate synchronously, which in turn drives multiple threaded rods 202 to rotate synchronously. Since the threaded rods 202 are threadedly connected to the push plate 201, the push plate 201 slides in the sliding groove 205, gradually pushing the decorative wall panel 7 to the installation position and fixing it. Since all the threaded rods 202 rotate synchronously, the decorative wall panel 7 can be moved stably, avoiding local installation instability.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
