When it is necessary to fix the keel assembly and the ceiling, in order to ensure that the keel assembly is accurately installed at the installation point on the ceiling, the rubber strip 2 is provided to facilitate fixing the rack 1 to the wall by bonding. The rubber strip 2 is a disposable item. When it is necessary to assemble multiple sets of keel assemblies, the rubber strip 2 can be torn off from the side wall of the rack 1, so as to facilitate replacement of the rubber strip 2. After the rack 1 is bonded to the wall by the rubber strip 2, the gear 9 is rolled along the rack 1 to adjust the height of the threaded telescopic assembly and the elastic support assembly in the vertical direction, and thus the installation height of the keel assembly can be adjusted and limited. The spring 24 is provided to allow the telescopic plate 19 to slide along the slide 7, so that the gear 9 and the rack 1 are disengaged. This can adjust the initial position of the gear 9 equivalent to the rack 1 when the threaded telescopic assembly is at the minimum telescopic distance. When the gear 9 rolls along the rack 1, the rotating column 21 can drive the threaded telescopic assembly to extend and retract in the lateral direction. By installing the keel assembly between the threaded telescopic assembly and the elastic support assembly, the threaded telescopic assembly can press the keel assembly against the elastic support assembly when extended, thereby ensuring the stability of the keel assembly during the height adjustment process.

During assembly, the keel assembly is placed between the clamping block 17 and the positioning block 25. After the clamping block 17 and the positioning block 25 are docked, the clamping block 17 and the positioning block 25 are used to support the keel assembly from the left and right sides. The spring 16 is provided so that when the clamping block 17 and the positioning block 25 are fitted together and the gear 9 has not reached the set installation height, the positioning block 25 is prevented from jamming the clamping block 17, thereby ensuring that the gear 9 can move the keel assembly to the set installation height.

[0031] Further, the keel assembly includes a keel plate 2 5 and a strip hole 10, the strip hole 10 is opened on the surface of the keel plate 2 5, and the inner diameter of the strip hole 10 and the outer diameter of the block 17 are mutually adapted, the keel assembly also includes a suspension rod 34, and the suspension rod 34 and the keel plate 2 5 are threadedly connected, and the bottom outer wall of the keel plate 2 5 is fixed with the keel plate 1 4 by bolts; The strip holes 10 are provided to facilitate connection between the keel plate 2 5 and the threaded telescopic assembly and the elastic support assembly. The keel plate 2 5 and the ceiling can be fixedly connected by the hanger 34. The keel plate 1 4 can be provided to lay and fix the ceiling decorative panel. The strip holes 10 are provided in a strip shape to facilitate small-range adjustment of the installation position of the keel plate 2 5 in the horizontal direction.
