[0030] In the disclosed embodiment, the first plug-in slot and the second plug-in slot are symmetrical structures symmetrical with respect to the central plane of the wall connection part, and the central plane is a plane passing through the center of the wall connection part and perpendicular to the wall connection part. The groove depth of the first plug-in slot is the same as the groove depth of the second plug-in slot, and the groove wall width of the first plug-in slot is the same as the groove wall width of the second plug-in slot. The groove wall width refers to the vertical distance between the two groove walls of the first plug-in slot or the second plug-in slot. This solution can enable the first plug-in slot and the second plug-in slot to dock with different plug-in protrusions.

[0031] like Figure 2 The figure shows a schematic diagram of the splicing and installation of the first wall panel molding line component 100 and the decorative panel 300. The I-shaped connector has a first plug-in portion 201, a second plug-in portion 202 and a connecting portion 203 with a nail groove. The first plug-in portion 201 is plugged into the second plug-in groove 130 of the first wall panel molding line component 100, and the second plug-in portion 202 is plugged into the decorative panel groove of the decorative panel 300.

The first raised portion is connected between the wall connection portion and the first plug-in slot, and its height is equal to the thickness of the upper portion of the veneer groove of the corresponding veneer panel, so that the first plug-in slot can be parallel to the veneer groove at the end of the veneer panel. Similarly, the function of the second raised portion is the same as that of the first raised portion. The first raised portion and the second raised portion are designed as inclined structures, which can reserve installation space for the wall panel molding line components and improve installation convenience.

[0033] In the embodiment of the present disclosure, the third raised portion 173 is formed by vertically extending upward from the upper end of the third shaping portion, and the height of the third raised portion is equal to the thickness of the portion below the decorative panel groove of the corresponding decorative panel, so that the third shaping portion can be completely exposed to the outside of the decorative panel, thereby increasing the aesthetics of the wall.

[0034] In the disclosed embodiment, the connection between the left end of the lower groove wall of the first plug-in groove and the upper end of the first molding portion is provided with a chamfer structure including a first chamfer surface 181, and the connection between the upper end of the third raised portion and the right end of the lower groove wall of the second plug-in groove is provided with a chamfer structure including a second chamfer surface 182. The chamfer structure can be designed to reserve installation space for the wall panel molding line components, thereby improving installation convenience.

[0035] like Figure 3 The wall shape shown is formed by splicing and installing a first wall panel shape line component 501, a first wall panel shape line component 502, a first wall panel shape line component 503, a first wall panel shape line component 504 and a decorative panel.

[0036] In some embodiments of the present disclosure, Figure 4 As shown, the wall panel molding line assembly may also include a connecting piece, a first wall panel molding line component 601 and a second wall panel molding line component 602.

The corresponding plug-in slot is a plug-in slot with a slot direction opposite to that of the first plug-in slot of the first wall panel molding line component. Left-right mirror-symmetry is relative to Figure 4Furthermore, the second wall panel molding line member 602 can have the same structure as the first wall panel molding line member 601. When in use, the first wall panel molding line member 601 is rotated 180 degrees on the plane where the wall is located to obtain the second wall panel molding line member 602. Specifically, adjacent placement refers to placement in an adjacent and connected state.

[0037] like Figure 4 As shown, one end of the connecting piece 700 is inserted into the first plug-in slot of the first wall panel molding line member 601, and the other end is inserted into the plug-in slot on the right side of the second wall panel molding line member 602.
