[0024] like Figure 1 As shown, the third trough 13 is C-shaped as a whole, including a straight plate-shaped bottom wall 130 and bent edges 131 at both ends. The bottom wall includes an inner wall surface 1301 and an outer wall surface 1302, and the outer wall surface 1302 constitutes the support plane of the wall leveling fixing support member 200.

[0025] like Figure 1 As shown, the first trough body 11 includes a straight plate portion 110, and the second trough body 12 includes a straight plate portion 120. The bent edge 131 of the third trough body 13 and the straight plates 110 and 120 are located on the same side as the inner wall surface 1301 of the third trough body 13, and together form a support plane for the plate 300. The first trough body 11 also includes a connecting portion 111 connected to the straight plate portion 110 and extending rearward from the outer wall surface 1302 of the third trough body 13, and a bent portion 112 that bends inward from the connecting portion 111 and is used to snap onto the wall-leveling and fixing support member 200. The second trough body 12 also includes a connecting portion 121 connected to the straight plate portion 120 and extending rearward from the outer wall surface of the third trough body 13, and a bent portion 122 that bends inward from the connecting portion 121 and is used to snap onto the wall-leveling and fixing support member 200. The bent portions 112 and 122 are both provided with hooks 1120 and 1220 that are bent toward the inner wall surface 1201 of the third trough body and used for clamping the wall leveling and fixing support member 200 .

[0026] like Figure 2 As shown, the leveling keel 100 in this embodiment is designed to be continuous. The third trough 13 is provided with connection holes 132 for adapting and connecting to the wall leveling fixed support member 200. Multiple connection holes 132 are provided, spaced apart along the length of the leveling keel 100. The leveling keel 100 in this embodiment is an integrally molded structural member manufactured by extrusion.

[0027] like Figure 3 As shown, when the leveling keel 100 provided in an embodiment of the present invention is used to connect the wall-leveling fixed support member 200 and the plate 300, the wall-leveling fixed support member 200 is first installed on the base wall 400 and the base wall 400 is leveled. Then, the leveling keel 100 of this embodiment is connected to the wall-leveling fixed support member 200. Finally, the leveling fixed support member 200 is fixedly connected to the plate 300.

[0028] Among them, the third groove body 13 of the leveling keel 100 of this embodiment constitutes the first connection point connected to the wall leveling fixed support member 200, and the bent edge 131 of the leveling keel 100 constitutes the first support with the plate 300; the bent portions 112 and 122 of the first groove body 11 and the second groove body 12 of the leveling keel 100 respectively constitute the second connection point and the third connection point connected to the wall leveling fixed support member 200, and the straight plate portions 110 and 120 constitute the first and second connections connected to the plate 300.

[0029] The first trough body 11, the second trough body 12, and the third trough body 13 of the leveling keel 100 of this embodiment have a compact structural design, provide stable support and fixation, ensure sufficient installation space, and are quickly and conveniently connected to the wall leveling fixed support member 200 and the plate 300.

[0030] An embodiment of the present invention further provides a leveling device, comprising the above-mentioned leveling keel 100 and a leveling fixed support member 200 installed in conjunction with the leveling keel 100 . The leveling fixed support member 200 is installed on a base wall and performs leveling on the base wall.

[0031] like Figure 4 、 Figure 5 As shown, the leveling support member 200 includes a support plate 20 and a fixing portion 21 extending rearward from the support plate 20 for connection to the base wall 400 and adjustable within the base wall 400. The fixing portion 21 has an expandable inner cavity 210 and an outer connecting screw 211. The support plate 20 includes a snap portion 201 at its upper and lower ends, respectively, and a boss portion 202 located between the snap portions 201. A groove portion 203 is formed between the snap portion 201 and the boss portion 202, with its opening facing away from the extending direction of the fixing portion 21. The snap portion 201 has a curved portion 2011, which curves in a direction opposite to the opening direction of the groove portion 203. A notch 2011-a is provided at the opposite end of the curved portion 2011 from the groove portion 203. The boss portion 202 has an opening 2021 communicating with the inner cavity 110. The leveling and fixing support member 200 further includes an adjusting nut 22 adapted to the fixing portion 21 (see FIG. Figure 3(As shown), rotating the adjustment nut 22, through the interaction between the internal threads of the adjustment nut 22 and the connecting and securing threads 211, can drive the fixing portion 21 to move relative to the base wall 400, thereby adjusting the extension of the fixing portion 21 beyond the base wall 400, thereby adjusting the position of the support plate 20 and adjusting the flatness of the base wall 400. The wall-leveling fixing support member 200 can be made of a low-cost plastic material, and the adjustment nut 22 can be made of a flame-retardant plastic component with high toughness and stability. The leveling fixing support member 200 of this embodiment of the present invention is a one-piece component.

[0032] When the leveling fixed support member 200 is installed in conjunction with the base wall 400 for leveling, multiple holes are first drilled in the base wall 400, into which multiple wall-leveling fixed support members 200 are inserted. Each wall-leveling fixed support member 200 is then leveled using the adjusting nut 22. The adjusting nut 22 drives the fixing portion 21 to adjust the length of the fixing portion 21 extending from the base wall 400, thereby adjusting the distance between the support plate portion 20 and the base wall 400. This allows the support plates 20 of multiple wall-leveling fixed support members 200 to be aligned, achieving the goal of leveling the base wall 300 surface, thereby allowing the panels 200 to be installed on the adjusted surface. The wall-leveling fixed support member 200 of this embodiment facilitates adjustment of the overall flatness of the base wall 400 surface and offers flexible adjustment.

[0033] When connecting the leveling keel 100 of this embodiment to the leveling fixed support member 200, the bent portions 112 and 122 of the leveling keel 100 first engage with the two snap-fit portions 201 of the leveling fixed support member 200. The boss portion 202 abuts against the outer wall 1302 of the third trough 13, with the connecting hole 132 aligned with the opening 2021. Self-tapping screws 50 are then driven through the connecting holes 132 and opening 2021 into the inner cavity 210 of the fixing portion 21, expanding the inner cavity 210 and thus securing the wall leveling fixed support member 200 to the foundation wall 400.

[0034] When the leveling keel 100 of this embodiment is connected to a panel, the straight plate portions 110 and 120 of the first and second troughs 11 and 12 rest against the panel 300, and screws or other fasteners are then used to secure the straight plate portion 120 to the panel 300. The third trough 13 forms a space for installing the self-tapping screws 50 when connecting to the wall-leveling fixed support member 200. The first and second troughs 11 and 12 form a space for installing screws or other fasteners when connecting to the panel 300. The connecting portions 121 and 122 of the leveling keel 100 ensure the formation of the groove portion 203 of the wall-leveling fixed support member 200, thereby providing elastic space for the bend portion 122 to engage and snap into place with the snap portion 201.

[0035] The aforementioned foundation wall 400 can be a masonry wall, cast concrete wall, or the like. The panel 300 can be a quick-install concealed profile, a decorative integrated panel, or a combination of a quick-install concealed profile and a decorative integrated panel. The wall leveling fixed support member 200 is suitable for quickly leveling masonry walls, cast concrete walls, and other wall surfaces, and is suitable for wall flatness tolerances between 0mm and 45mm. The Qingming leveling fixed support member 200 connects the dedicated supporting keel to the foundation wall, ultimately achieving the connection between the concealed quick-install profile, the decorative integrated panel, and the foundation wall.

[0036] The leveling keel 100 of the present invention simultaneously performs leveling, fixing, and supporting functions. It features a simple structure, convenient adjustment, and highly stable connection, resolving the issue of multiple and complex leveling tools currently available. Furthermore, the leveling keel 100 of the present invention meets the requirements for rapid wall leveling in a dry, non-wet operation model, further simplifying the leveling process.
