Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-4 This utility model provides a technical solution for an adjustable-angle ceiling keel connector, including a fixing plate 1, a locking block 2, a locking groove 3, a main connecting rod 4, a limiting hole 5, a secondary connecting rod 6, a rod body 601, a sliding rod 602, a compression spring 603, a connecting plate 604, a limiting buckle 605, a sliding groove 7, a clamping block 8, a slider 9, a limiting groove 10, a threaded rod 11, a limiting block 12, a worm gear 13, a rotating rod 14, a worm wheel 15, a clamping rod 16, a limiting rod 17, and a return spring 18.

[0030] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 2 As shown, the fixing plates 1 are connected to each other by the engagement of the locking block 2 and the locking groove 3, and the fixing plate 1 is slidably connected to the main connecting rod 4 by the sliding block 9. The sliding block 9 and the main connecting rod 4 are welded as an integral structure. The main connecting rod 4 has a "+" shaped structure, and both ends of the main connecting rod 4 are threaded with threaded rods 11. The upper end of the threaded rod 11 is rotatably connected to a limiting block 12. At the same time, the limiting block 12 is slidably connected to the side wall of the main connecting rod 4 through a limiting groove 10. According to the original top surface dimensions, the fixing plate 1 is fixedly installed on the top surface by bolts. The fixing plates 1 are spliced ​​together by the engagement of the locking block 2 and the locking groove 3, so that the corresponding number of fixing plates 1 can be installed according to the required size. Then, the main connecting rod 4 slides on the sliding groove 7 through the slider 9, so that the main connecting rod 4 can support the keel and the position of the main connecting rod 4 can be easily adjusted. Rotating the threaded rod 11 adjusts the limiting block 12 to slide on the limiting groove 10, so that the limiting block 12 can contact the lower end face of the fixing plate 1, so as to limit and fix the position of the main connecting rod 4, prevent slippage, and provide stable support and fixation for easy use.

[0031] Combination Figure 1 , Figure 3 and Figure 4As shown, the secondary connecting rod 6 includes a rod body 601, a sliding rod 602, a compression spring 603, a connecting plate 604, and a limiting buckle 605. The limiting buckle 605 is connected through the upper right side wall of the rod body 601. The connecting plate 604 is integrally fixedly connected to the left side of the limiting buckle 605. The sliding rod 602 is connected through both the front and rear ends of the connecting plate 604. The sliding rod 602 is fixedly connected to the upper interior of the rod body 601. The compression spring 603 is sleeved on the outer surface of the sliding rod 602. The compression spring 603 is located on the left side of the connecting plate 604. The limiting buckle 605 forms a telescopic structure on the sliding rod 602 through the connecting plate 604. The lower end face of the limiting buckle 605 has an arc-shaped structure, and the size of the limiting buckle 605 is smaller than the size of the limiting hole 5. At the same time, the limiting holes 5 are equally spaced on the right side of the main connecting rod 4. The rod body 601 passes through the interior of the main connecting rod 4, and the lower end of the rod body 601 has a "U" shaped structure. The lower end of the rod body 601 is rotatably connected to a worm gear 15. The secondary connecting rod 6 passes through the interior of the main connecting rod 4. The total length of the main connecting rod 4 and the secondary connecting rod 6 can be adjusted according to the required installation height of the ceiling to facilitate clamping and fixing of the keel at different heights and to facilitate use. The limiting buckle 605 is telescopically adjusted on the rod body 601 through the sliding rod 602, so as to facilitate the adjustment of the position of the rod body 601 inside the main connecting rod 4. The limiting buckle 605 is correspondingly set with the limiting hole 5 to facilitate the fixing of the length of the secondary connecting rod 6 and the main connecting rod 4. When retracted, the lower end of the limiting buckle 605 is arc-shaped, which facilitates the extension and retraction of the rod body 601 into the interior of the main connecting rod 4, thus facilitating the retraction process.

[0032] Combination Figure 1 and Figure 3 As shown, a worm gear 13 is meshed with the upper side of the worm wheel 15, and the worm gear 13 is rotatably connected to the lower front surface of the secondary connecting rod 6. A clamping rod 16 is integrally connected to the rear side of the worm wheel 15 via a central shaft. The clamping rod 16 is rotatably connected to the lower end of the rod body 601 via the worm wheel 15. The lower end of the clamping rod 16 forms a telescopic structure with the clamping block 8 via a limiting rod 17. The clamping block 8 has an "L" shape, and its rear end face is flush with the rear end face of the clamping rod 16. When the ceiling is perpendicular to the top surface or has an inclined angle, rotating the rotating rod 14 drives the worm gear 16. When rod 13 rotates, worm gear 13 and worm wheel 15 mesh and connect, which facilitates the rotation of clamping rod 16 at the lower end of secondary connecting rod 6 by a certain angle, thereby facilitating the support and fixation of the keel. At the same time, clamping block 8 is pulled outward, and return spring 18 is compressed, which facilitates the adjustment of the distance between clamping block 8 and clamping rod 16, so that clamping block 8 and clamping rod 16 can be clamped on the outer surface of the keel. This allows for easy traction and pulling through secondary connecting rod 6 and main connecting rod 4, facilitating installation and fixation. This is the working process of the adjustable-angle ceiling keel connector.
