The adjustable connection structure of the assembled ceiling of the utility model is different from the prior art in that it includes a cross connector 30, a ball node conversion component 40, a ceiling conversion ring 50, a screw 60, and a keel conversion component 70.

[0023] like Figure 4-5 As shown, a cross connector 30 is fixedly connected below each node ball. The cross connector 30 is a rectangular plate vertically connected to each other to form a cross shape; the cross connector is adapted downward to be inserted into the cross groove of the ball node conversion component 40 below, and the two are fixed by bolts. The ball node conversion component 40 includes a flat base 41, on which four vertical plates 42 are vertically connected. The four vertical plates are divided into two parallel rows facing each other and spaced apart. The two vertical plates in each row are also parallel to each other and spaced apart, thus forming a cross groove for accommodating the cross connector; screws cross the rectangular plate of the cross connector 30 and the vertical plates 42 for fixing. A reinforcing plate 43 is connected between the four vertical plates 42 of the ball node conversion component 40 and the base 41, so that the strength is higher.

[0024] A vertical through hole is provided in the center of the base 41 of the ball node conversion component 40, and a part of the vertical plate 42 is removed around it. The upper end of a screw rod 60 passes through the vertical through hole and is fixed above the base 41 with a nut. The part where the vertical plate 42 is removed just accommodates the top of the screw rod 60 and the nut thereon, which are located below the cross connector. The lower end of the screw rod 60 is threadedly connected to the center of a ceiling conversion ring 50. The ceiling conversion ring 50 is approximately hub-shaped, and four support plates 52 are radially connected in the annular ring wall 51. The lower end of the screw rod 60 is connected to the threaded hole in the center of the intersection of the four support plates.

[0025] The inner sides of a plurality of spaced-apart keel conversion components 70 are clamped on the outer ring wall 51 of the ceiling conversion ring 50. The keel conversion components 70 can slide along the ring wall to adjust to the best position and then be fixed. The outer side of each keel conversion component 70 is connected to the main keel 81, and the connection angle is adjustable. Figure 4 and Figure 5As shown, each of the keel conversion components 70 is composed of two U-shaped grooves connected as one body, and the outer groove wall of the inner U-shaped groove 71 is integrally connected to the groove bottom of the outer U-shaped groove 72; the inner U-shaped groove 71 opens downward and is stuck on the annular wall 51, with the lower end exceeding the annular wall, and the screws are transversely connected to the notch of the inner U-shaped groove 71 and located below the annular wall; the notch of the outer U-shaped groove 72 is away from the annular wall 51 and outward to accommodate the keel 80 extending into it, and then the screws are transversely passed through the outer U-shaped groove 72 and the keel to tighten them.

[0026] In order to achieve fastening and angle adjustment, the outer U-shaped groove member 72 is provided with two horizontally parallel connecting holes for connecting the keel, wherein the inner connecting hole close to the annular wall 51 is a circular hole 721, and the outer connecting hole away from the annular wall is an arc-shaped long hole 722, and the arc center of the arc-shaped long hole is the center of the circular hole. Figure 5 As shown, the arc angle of the arc-shaped slot 722 is greater than or equal to 15°. The screw can slide in the arc-shaped slot and be tightened after being adjusted to the desired installation position. In this way, the connection angle of the main keel 81 can be adjusted in the vertical direction.

[0027] The keel 80 includes a main keel 81, a secondary keel 82 and a main keel adapter 84; the main keel adapter 84 has a vertical adapter seat 841, and the first connecting block 842 and the second connecting block 843 are fixed integrally on both sides of the adapter seat 841. The first connecting block 842 is preferably a square tube, which extends into the U-shaped groove 72 adapted to the outer side. A screw passes through the circular hole 721 to connect the first connecting block 842 and the U-shaped groove 72 on the outer side, and another screw passes through the arc-shaped long hole 722 to connect the first connecting block 842, and the angle of the first connecting block 842 is adjusted and locked. The second connecting block 843 is a square tube, the end of the main keel 81 is inserted into it, and the two are fastened by two vertically arranged screws. The size of the second connecting block 843 of the main keel adapter 84 can be customized according to the size of main keels of different specifications, so that the assembly system can adapt to the needs of main keels of different sizes without changing other components. It can be seen that the system has wide adaptability and saves costs.
