[0022] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be arbitrarily combined with each other.

[0023] As Figures 1-3 shown, an embodiment of the present invention provides a leveling and fixing support member 100, including: a support plate portion 10 for connecting a plate 200 or a keel 400, and a fixing portion 11 extending backward from the support plate portion 10 for connecting to a base wall 300 and adjustable within the base wall 300. An expandable inner cavity 110 is provided inside the fixing portion 11, and a connecting and clamping thread 111 is provided outside. The support plate portion 10 includes a clamping portion 101 provided at each of the upper and lower ends, and a boss portion 102 located between the clamping portions 101 at the upper and lower ends. A groove portion 103 with an opening direction opposite to the extending direction of the fixing portion 11 is formed between the clamping portion 101 and the boss portion 102. The clamping portion 101 is provided with a bending portion 1011 whose bending direction is opposite to the opening direction of the groove portion 103, and a notch 1011-a is provided at the opposite end of the bending portion 1011 from the groove portion 103. The boss portion 102 is provided with an opening 1021 communicating with the inner cavity 110. The leveling and fixing support member 100 of the embodiment of the present invention further includes an adjusting nut 12 adapted to the fixing portion 11. By rotating the adjusting nut 12, under the interaction between the internal thread of the adjusting nut 12 and the connecting and clamping thread 111, the fixing portion 11 can be driven to move relative to the base wall 300, so as to adjust the length of the fixing portion 11 extending outside the base wall 300, thereby adjusting the position of the support plate portion 10 and realizing the adjustment of the flatness of the base wall 300. The leveling and fixing support member 100 of the embodiment of the present invention can be made of a plastic material with a relatively low cost, and the adjusting nut 12 can be made of a flame-retardant plastic member and has high toughness and stability. The leveling and fixing support member 100 of the embodiment of the present invention is an integral member.

[0024] As Figure 2 shown, when the leveling and fixing support member 100 provided by the embodiment of the present invention is applied to the connection between the plate 200 and the base wall 300, during installation, first, a plurality of holes are drilled in the base wall 300, and a plurality of leveling and fixing support members 100 are correspondingly inserted. Then, the adjusting nut 12 is used to level each leveling and fixing support member 100 with respect to the base wall 300. The adjusting nut 12 drives the fixing portion 11 to move to adjust the length of the fixing portion 11 extending outside the base wall 300, so as to adjust the distance between the support plate portion 10 and the base wall 300. It can make the support plate portions 10 of a plurality of leveling and fixing support members 100 be in one plane, and the purpose of leveling the wall surface of the base wall 300 can be achieved, so that the plate 200 can be installed on the adjusted plane. The leveling and fixing support member 100 of this embodiment is convenient for adjusting the overall flatness of the wall surface of the base wall 300, and the adjustment is flexible.

[0025] In this embodiment, the support plate portion 10 supports and positions the plate material 200 mainly by connecting the support plate portion 10 and the support positioning plate material 200 through the keel 400. In other embodiments, the support plate portion 10 can also be directly fixedly connected to the plate material 200, and the connection method can refer to the connection method with the keel 400, which is not limited herein.

[0026] An embodiment of the present invention further provides a leveling device, including a leveling fixed support member 100 and a keel 400 cooperatively installed with the leveling fixed support member 100. The keel 400 can connect the leveling fixed support member 100 and the plate material 200.

[0027] As Figure 4 、 5 shown, the keel 400 is provided in a full length, and is of an overall bent structure, and can be cooperatively installed with a plurality of leveling fixed support members 100 along the full length direction. The keel 400 includes first troughs 40 provided at the upper and lower ends and a second trough 41 located between the first troughs 40 at the upper and lower ends. The opening directions of the first troughs 40 at the upper and lower ends are the same, and the opening direction of the second trough 41 is opposite to that of the first trough 40. The second trough 41 includes an inner wall surface 411 and an outer wall surface 412. Each of the first troughs 40 at the upper and lower ends includes a support plate portion 401 on the same side as the inner wall 411 of the second trough 41 and a bent portion 402 that protrudes backward on the same side as the outer wall surface 412 of the second trough 41. The bent portion 402 is bent inward. Connection holes 410 are provided in the second trough 41.

[0028] When fixedly connecting the support plate portion 10 and the plate material 200, first, the leveling fixed support member 100 is cooperatively installed with the keel 400. Among them, the bent portion 402 is cooperatively buckled with the buckle portion 101, and the bent portion 402 constitutes the first connection part with the keel 400. The convex portion 102 abuts against the outer wall surface 412 of the second trough 41, the connection hole 410 corresponds to the opening 1021, and the convex portion 102 constitutes the second connection part with the keel 400. Then, a self-tapping screw 50 is screwed into the inner cavity 110 of the fixing portion 11 from the connection hole 410 and the opening 1021 to expand the inner cavity 110, playing the role of the principle of expansion and fixation of a traditional expansion bolt, so as to fixedly connect the leveling fixed support member 100 and the base wall 300. Then, the keel 400 is fixedly connected to the plate material 200. Specifically, the support plate portions 401 of the first troughs 40 at the upper and lower ends are abutted against the plate material 200, and then the support plate portions 401 and the plate material 200 are fixed by using a screw or other connecting member. The second trough 41 forms an installation space for the self-tapping screw 50 when connecting with the leveling fixed support member 100. The first troughs 40 at the upper and lower ends form an installation space for a screw or other connecting member when connecting with the plate material 200. The groove portion 103 provides an elastic space when the bent portion 402 is cooperatively buckled with the buckle portion 101.

[0029] In the embodiments of the present invention, the base wall 300 can be a masonry wall, a cast-in-place concrete wall, etc. The plate 200 can be a concealed plug-in quick-install profile, a decorative integrated board, or a combined structure of a concealed plug-in quick-install profile and a decorative integrated board, etc. The leveling and fixing support member 100 is applicable to quickly level the walls such as masonry walls and cast-in-place concrete walls, and is applicable to the situation where the wall surface flatness error is 0 mm - 45 mm. The leveling and fixing support member 100 can realize the connection between the special supporting keel and the base wall, and finally realize the connection between the concealed plug-in quick-install profile, the decorative integrated board and the base wall.

[0030] The leveling and fixing support member 100 in the embodiments of the present invention can simultaneously play the roles of leveling, fixing, and supporting, with a simple structure, convenient adjustment, and high connection stability, solving the problem of many and complex existing leveling tools. And the leveling and fixing support member 100 in the embodiments of the present invention can meet the process requirements of quickly leveling the wall surface under the wet and dry operation models, and the leveling process is more simplified.
