[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This type of adjustable keel composite wall is installed by setting up installation components, etc. During installation, the expansion bolts are first fixed to the wall, then the connection frame on one side is fixed to the keel body, and then the connection frame on the other side is fixed to the expansion bolts in turn. After the fixing is completed, the wall panel can be adsorbed and fixed to the side wall of the keel body by a magnet, and the angle and position of the keel body can be adjusted by adjusting the wall panel.

[0016] (2) This type of adjustable keel composite wall, by setting a detection mechanism, etc., after the limit is completed, the hydraulic oil in the fixed cover is squeezed, at this time, the pressure in the fixed cover becomes larger, which can push the second moving rod to move upward, and at the same time, drive the moving block to move upward along the second T-shaped guide rod, the fourth spring is compressed, and when the moving block moves upward, it can drive the push pin to slide in the slide groove through the fixed block, so that the pointer can be pushed to rotate upward along the shaft. At this time, the pointer indicates a certain scale on the scale plate.

[0030] Working principle: When in use, during installation, first fix the expansion bolt 1402 on the wall 13, then fix the connection frame 1401 on one side to the keel body 1, then fix the connection frame 1401 on the other side to the expansion bolt 1402 in turn, after the fixing is completed, the wall panel 11 can be adsorbed and fixed to the side wall of the keel body 1 by the magnet 12, and the angle and position of the keel body 1 can be adjusted by adjusting the wall panel 11. During the adjustment, the universal ball 1501 can rotate adaptively, and at the same time, the spline rod 1502 can move adaptively in the spline sleeve 1503, so as to facilitate the adjustment of the angle and position of the keel body 1, and then adjust the angle and position of the wall panel 11, so as to ensure the installation efficiency and quality of the wall panel 11; After the adjustment is completed, the sliding plate 702 can be pushed by the toggle plate 703, and at the same time, the moving plate 602 is driven to move by the first moving rod 701. At this time, the hydraulic oil in the fixed cover 601 can be squeezed, so that the hydraulic oil enters the first fixed pipe 203 and the hose 603 through the hose 603, and the first sliding plate 401 and the first limiting rod 204 can be pushed to move downward. At the same time, the first spring 402 is compressed, and the first limiting rod 204 is inserted into the first limiting hole 201 for limiting. At the same time, the second sliding plate 501 and the second limiting rod 304 can be pushed to move downward. At the same time, the second spring 502 is compressed, and the second limiting rod 304 is inserted into the second limiting hole 301 for limiting. When the semicircular groove 801 moves to the bottom of the latch 802, the slider 804 and the latch 802 can move downward under the action of the third spring 805, and the latch 802 is inserted into the semicircular groove 801 for limiting. At this time, the limiting operation of the installation component is realized, which can improve the efficiency and quality of installation. Moreover, even if the drilling hole of the expansion bolt 1402 is offset, or in order to avoid adjusting the drilling position of the steel bar, the keel body 1 and the wall panel 11 can be normally installed and fixed through adjustment, which has stronger applicability, is more convenient and quick to use, and can improve the efficiency and quality of installation. After the limit is completed, the hydraulic oil in the fixed cover 601 is squeezed. At this time, the pressure in the fixed cover 601 becomes larger, which can push the second moving rod 1009 to move upward. At the same time, the moving block 902 is driven to move upward along the second T-shaped guide rod 901. The fourth spring 903 is compressed. When the moving block 902 moves upward, the push pin 1008 can be driven to slide in the slide groove 1007 through the fixed block 1006, so that the pointer 1003 can be pushed to rotate upward along the rotating shaft 1002. At this time, the pointer 1003 indicates a certain scale of the scale plate 1005. If a leak occurs in the hydraulic system, the pressure in the fixed cover 601 will gradually decrease, the upward movement stroke of the second movable rod 1009 will become smaller, and the rotation angle of the pointer 1003 will become smaller, so that the scale on the scale plate 1005 indicated by the pointer 1003 will become smaller. After the installation is completed, it is convenient to detect the pressure in the fixed cover 601 to avoid leakage, thereby ensuring that the limiting effect of the first limiting rod 204 and the second limiting rod 304 is more stable and reliable.
