[0012] As a further technical solution, the connecting piece has a right-angle structure and is attached to the keel crossbeam.

[0013] As a further technical solution, one end of the locking pin extends out of the drive cavity, and the other end of the locking pin is inserted into the side wall of the keel frame.

[0014] As a further technical solution, the keel prism and the keel crossbar intersect to form a rectangular frame structure.

[0015] As a further technical solution, the insertion hole and the locking bolt are connected by a threaded screw, and the insertion hole is provided with an expansion hole, which is connected to the insertion hole.

[0035] like Figures 1-5 As shown, it illustrates a light steel keel ceiling structure of this disclosure, comprising:

[0036] Keel frame 1, with keel cross frame 2 inside keel frame 1;

[0037] The plug-in mounting component 3 is installed on the side wall of the keel frame 1;

[0038] Flip-connector component 4 is installed on the keel crossbeam 2;

[0039] The plug-in mounting assembly 3 includes a plug-in hole 3-1, which is located on the side wall of the keel crossbeam 2. A locking bolt 3-2 is inserted into the plug-in hole 3-1, and the knob end of the locking bolt 3-2 is attached to the keel frame 1. The keel crossbeam 2 has a drive cavity 3-3 inside, and a locking pin 3-4 is provided inside the drive cavity 3-3. A drive frame 3-5 is connected to the locking pin 3-4. A sliding groove 3-6 is provided on the keel crossbeam 2, and the sliding groove 3-6 is connected to the drive cavity 3-3. A drive block 3-7 is provided at the upper end of the drive frame 3-5, and the drive block 3-7 is embedded in the sliding groove 3-6.

[0040] The flipping connection assembly 4 includes a connecting block 4-1, a connecting shaft 4-2 connected to the inner side wall of the connecting block 4-1 by a pin, a swing frame 4-3 mounted on the connecting shaft 4-2, a flipping shaft 4-4 mounted on the swing frame 4-3, a connecting piece 4-5 mounted on the flipping shaft 4-4, and a movable connection between the connecting piece 4-5 and the rotation shaft 3-9 via a bearing.

[0041] In some examples, the keel crossbeam 2 is placed inside the keel frame 1 so that the two intersect to form a rectangular frame structure. The keel crossbeam 2 is initially fixed according to the designed spacing and position.

[0042] Install the locking bolt 3-2 in the insertion hole 3-1 on the side wall of the keel cross frame 2 by screwing it in. During the screwing process, ensure that the knob end of the locking bolt 3-2 fits tightly against the keel cross frame 1.

[0043] Install a locking pin 3-4 in the drive cavity 3-3 of the keel cross frame 2, and connect the locking pin 3-4 to the drive frame 3-5. The drive block 3-7 at the upper end of the drive frame 3-5 is embedded in the sliding groove 3-6.

[0044] On the inner side wall of the connecting block 4-1, the connecting shaft 4-2 is installed by means of a pin connection, and the swing frame 4-3 is mounted on the connecting shaft 4-2 to ensure that the swing frame 4-3 and the connecting shaft 4-2 are movably inserted and connected, and can swing flexibly.

[0045] Install the connecting piece 4-5 on the connecting shaft 4-2 of the swing frame 4-3 so that the connecting piece 4-5 is movably connected to the rotation shaft 3-9 through the bearing. Since the connecting piece 4-5 is a right-angle structure, it needs to be attached to the keel cross frame 2 to achieve a stable connection.

[0046] like Figures 1-5As shown, in this embodiment, the locking bolt 3-2 has an adjustment hole 3-8 at its end, a self-rotating shaft 3-9 is embedded in the adjustment hole 3-8, a tension pin 3-10 is provided at one end of the self-rotating shaft 3-9, and a tension sleeve 3-11 is provided on the tension pin 3-10.

[0047] In some examples, a spindle 3-9 is embedded in the adjusting hole 3-8 at the end of the locking bolt 3-2, a tension pin 3-10 is installed at one end of the spindle 3-9, and a tension sleeve 3-11 is fitted onto the tension pin 3-10.

[0048] For example, such as Figure 2 As shown, the connecting piece 4-5 has a right-angle structure and is attached to the keel crossbeam 2.

[0049] For example, such as Figure 1 As shown, one end of the locking pin 3-4 extends out of the drive cavity 3-3, and the other end of the locking pin 3-4 is inserted into the side wall of the keel frame 1. The keel frame 1 and the keel cross frame 2 intersect to form a rectangular frame structure.

[0050] For example, such as Figure 2 As shown, the insertion hole 3-1 and the locking bolt 3-2 are connected by threaded screwing. An expansion hole 5 is provided on the insertion hole 3-1, and the expansion hole 5 is connected to the insertion hole 3-1. A semi-circular limiting arc surface 6 is provided on the inner bottom surface of the drive cavity 3-3, and a relief groove 7 is provided on the inner bottom surface of the drive frame 3-5. The relief groove 7 fits against the semi-circular limiting arc surface 6.

[0051] In some examples, the expansion hole 5 makes it easier for the locking bolt 3-2 to be inserted into the insertion hole 3-1, and the relief groove 7 on the inner bottom surface of the drive frame 3-5 fits into the semi-circular limiting arc surface 6 on the inner bottom surface of the drive cavity 3-3 to achieve precise positioning.

[0052] For example, such as Figure 5 As shown, the swing frame 4-3 and the connecting shaft 4-2 are connected by a movable insert.

[0053] For example, such as Figure 4 As shown, a hexagonal knob 8 is provided on the locking bolt 3-2, and the adjustment hole 3-8 is opened on the hexagonal knob 8.

[0054] In some examples, the hexagonal knob 8 can be used to position and tighten the spindle 3-9 and related components during operation.

[0055] When using, align the locking bolt 3-2 with the insertion hole 3-1 on the side wall of the keel crossbeam 2, and use a wrench to tighten it clockwise. During the process, constantly observe the knob end of the locking bolt 3-2 to ensure it fits tightly against the keel crossbeam 1, ensuring a tight connection. If you encounter resistance when tightening, do not force it. Carefully insert the rotating shaft 3-9 into the adjustment hole 3-8 at the end of the locking bolt 3-2, and gently tap it with a small hammer to secure it in place. Install the expansion pin 3-10 on one end of the rotating shaft 3-9, and then put on the expansion sleeve 3-11. Use a wrench to turn the hexagonal knob 8 to fine-tune the rotating shaft 3-9, precisely adjusting the position of the expansion pin 3-10 and the expansion sleeve 3-11 to achieve a tight fit. On the inner side wall of the connecting block 4-1, use... The pin fixes the connecting shaft 4-2. The swing frame 4-3 is then placed on the connecting shaft 4-2. The swing frame 4-3 is gently shaken to check whether its movable insertion connection with the connecting shaft 4-2 is smooth and whether there is any jamming. The connecting piece 4-5 is installed on the connecting shaft 4-2 of the swing frame 4-3 to ensure that the connecting piece 4-5 and the rotating shaft 3-9 are movably connected through the bearing. Since the connecting piece 4-5 is a right-angle structure, it needs to be tightly fitted onto the keel cross frame 2. The connecting piece 4-5 is gently pushed by hand to check its stability. The wrench is used again to tighten the locking bolt 3-2 to the specified torque so that one end of the locking pin 3-4 extends out of the drive cavity 3-3 and smoothly inserts into the side wall of the keel frame 1, thus achieving reliable fixation between the keel frame 1 and the keel cross frame 2.

[0056] When other keel frames 1 and keel cross frames 2 are connected, the connecting pieces 4-5 can be flipped to a horizontal position so that the two fitting keel cross frames 2 are overlapped and fixed.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
