It further includes a second fastening structure 7. One end of the insertion plate 21 is inserted into the first slot 15, so that at least a part of the projection of the fourth fixing through hole 211 is located on the second fixing through hole 121. One end of the second fastening structure 7 sequentially passes through the third fixing through hole 141, the fourth fixing through hole 211, and the second fixing through hole 121 to tightly connect the clamping plate 14, the insertion plate 21, and the flat plate 12. When manufacturing the mounting member 1, the two ends of the second fixing through hole 121 and the third fixing through hole 141 are respectively aligned. The first slot 15 may be a rectangular body slot. The insertion plate 21 may be such that after one end of the insertion plate 21 is inserted into the first slot 15, by observation, the fourth fixing through hole 211 and the third fixing through hole 141 are aligned, thus achieving the alignment of the third fixing through hole 141, the fourth fixing through hole 211, and the second fixing through hole 121. The clamping plate 14 is located above the flat plate 12. After the wall panel is installed on the adjusting member 2 and the connecting plate 5 of the mounting member 1, a reinforcing plate 3 may be provided on the lower side of the flat plate 12 to enhance the bending resistance and avoid structural deformation. The vertical plate 11, the flat plate 12, the intermediate plate 13, and the clamping plate 14 are integrally formed. The width of the clamping plate 14 is smaller than the width of the flat plate 12, and the length of the clamping plate 14 is equal to the width of the flat plate 12. The width of the clamping plate 14 makes there be a gap between the clamping plate 14 and the vertical plate 11, which is convenient for observing the position of the insertion plate 21 inserted into the first slot 15. The second fastening structure 7 may include a fixing bolt and a fixing nut. After the third fixing through hole 141, the fourth fixing through hole 211, and the second fixing through hole 121 are all aligned and the position between the insertion plate 21 and the clamping plate 14 is adjusted, one end of the fixing bolt sequentially passes through the third fixing through hole 141, the fourth fixing through hole 211, and the second fixing through hole 121, and the other end of the fixing bolt abuts against the clamping plate 14. The fixing nut is screwed onto the part of the fixing bolt located at the lower end of the flat plate 12, and one side end of the fixing nut abuts against the flat plate 12, realizing the tight connection of the clamping plate 14, the insertion plate 21, and the flat plate 12.
[0031] The flat plate 12 may be perpendicular to the middle part of the vertical plate 11, the intermediate plate 13 is perpendicular to the flat plate 12, and the clamping plate 14 is parallel to the flat plate 12. After the first slot 15 is formed between the flat plate 12 and the clamping plate 14, it is convenient for the insertion plate 21 to be inserted into the first slot 15.
[0032] The adjusting member 2 may further include a protrusion 22 with one end connected to the other end of the insertion plate 21. The connecting plate 5 is connected to the other end of the protrusion 22. The cross-sectional area of the protrusion 22 is larger than that of the insertion plate 21. The bottom end of the protrusion 22 is flush with the bottom end of the flat plate 12 when the insertion plate 21 is inserted into the first insertion slot. The insertion plate 21 may be a rectangular plate, and the protrusion 22 may be a rectangular protrusion 22. The insertion plate 21 is perpendicular to the protrusion 22, and the connecting plate 5 is perpendicular to the protrusion 22. The middle of the connecting plate 5 is connected to the protrusion 22. The connecting plate 5, the insertion plate 21, and the protrusion 22 may be integrally formed.
[0033] As a wall leveling system in this embodiment, it may further include a spring 32. One end of the spring 32 is connected to the inner side wall of the guide chute 31, and the other end abuts against the support plate 4. The support plate 4 supports the insertion plate 21 to prevent the insertion plate 21 from being in a cantilever state after being fixed to the clamping plate 14 through the second fastening structure 7. The end of the support plate 4 abuts against the connecting plate 5. During the adjustment process, as the protrusion 22 moves in the direction close to the first slot 15 along with the insertion plate 21, it drives the connecting plate 5 to move in the direction close to the first slot 15. Then the connecting plate 5 pushes the support plate 4 to move in the direction close to the guide chute 31, compressing the spring 32, which facilitates inserting the support plate 4 into the guide chute 31. When the insertion plate 21 moves in the direction away from the first slot 15, it drives the protrusion 22 to move in the direction away from the first slot 15, driving the connecting plate 5 to move in the direction away from the first slot 15. Then the connecting plate 5 loses the thrust on the support plate 4, and the connecting plate 5 and the support plate 4 are separated. At this time, the spring 32 elongates, and the spring 32 pushes the other end of the support plate 4 to abut against the connecting plate 5, which can make the support plate 4 always support at the bottom end of the insertion plate 21.
[0034] The axis of the middle plate 13, the center line of the flat plate 12, and the center line of the clamping plate 14 may coincide. The insertion plate 21 is provided with a second slot 212, and the axis of the second slot 212 coincides with the center line of the insertion plate 21. The middle plate 13 is inserted into the second slot 212 when the insertion plate 21 is inserted into the second slot 212. The second slot 212 may be adapted to the middle plate 13. When the insertion plate 21 is inserted into the first slot 15, the third fixing through hole 141, the fourth fixing through hole 211, and the second fixing through hole 121 are aligned. After adjusting the position between the insertion plate 21 and the clamping plate 14, the insertion plate 21, the clamping plate 14, and the flat plate 12 are firmly connected through the second fastening structure 7.
[0035] The second fixing through holes 121 may be two symmetrically arranged about the center line of the flat plate 12, the third fixing through holes 141 are two symmetrically arranged about the center line of the clamping plate 14, the fourth fixing through holes 211 are two symmetrically arranged about the center line of the insertion plate 21, and the second fastening structure 7 may be two, which improves the connection stability of the clamping plate 14, the insertion plate 21, and the flat plate 12.
