[0026] Example 1:

[0027] This utility model proposes a quick-release ceiling keel.

[0028] In one embodiment of this utility model, the quick-release ceiling keel includes a hanger rod 1, a main keel 2, a secondary keel 3, and a sleeve 4. The main keel 2 is installed on the wall via the hanger rod 1. The sleeve 4 is detachably connected to the main keel 2 via a connector 5. The sleeve 4 is used to hold the connector 5 and the secondary keel 3. The sleeve 4 includes a fixed part 6, a movable part 7, and an elastic element 8. The movable part 7 is installed on the fixed part 6 via the elastic element 8 and can move towards or away from the fixed part 6.

[0029] Specifically, such as Figures 1 to 3As shown, in this utility model of quick-release ceiling keel, the two ends of the hanger 1 can be connected to the wall and the main keel 2 respectively through bolts or other fasteners. This allows the main keel 2 to be detachably installed on the wall, which not only facilitates disassembly and assembly but also ensures the stability of the secondary keel 3 and the ceiling panels. Furthermore, since the top of the sleeve 4 is detachably connected to the main keel 2 through the connector 5, the connector 5 can be a screw rod as used in the prior art. Screw rods are easy to manufacture and have a simple structure, thus allowing the connector 5 to be detachably installed on the main keel 2. The structural design is simple and reasonable.

[0030] Understandably, when the secondary keel 3 needs to be installed, since the movable part 7 in the sleeve 4 is installed onto the fixed part 6 via the elastic element 8, the construction worker can pull the movable part 7 away from the fixed part 6, and the elastic element 8 is in a stretched state. This allows the connecting part 5 and the secondary keel 3 to extend into the gap between the fixed part 6 and the movable part 7, respectively. After the connecting part 5 and the secondary keel 3 are installed in place, the construction worker releases the movable part 7. Under the rebound action of the elastic element 8, the movable part 7 moves towards the fixed part 6 until it connects with the connecting part 5. The connector 5 and the secondary keel 3 abut against each other, thereby enabling the clamp 4 to quickly clamp the connector 5 and the secondary keel 3, ensuring a stable connection between the connector 5 and the secondary keel 3 and the main keel 2. Similarly, when the secondary keel 3 needs to be disassembled, the construction personnel pull the movable part 7 away from the fixed part 6 again, thereby increasing the gap between the fixed part 6 and the movable part 7, so that the clamp 4 releases its clamp on the connector 5 and the secondary keel 3. At this time, the construction personnel can take out the connector 5 and the secondary keel 3 from the clamp 4, thus realizing the quick disassembly of the secondary keel 3.

[0031] Obviously, in the use of this utility model of quick-release ceiling keel, construction workers can quickly assemble and disassemble the secondary keel 3 and the main keel 2 simply by pulling the clamp 4. This is not only simple and convenient to operate, but also simplifies the overall connection structure, reduces material costs and manufacturing difficulty, and improves installation efficiency. In addition, since the movable part 7 of the clamp 4 can move relative to the fixed part 6, the clamp 4 can clamp secondary keels 3 of different specifications and sizes according to actual construction requirements, thereby achieving a stable connection between the main keel 2 and secondary keels 3 of different specifications and sizes, improving the flexibility of use.

[0032] In one embodiment, the bottom of the connector 5 has an annular flange 9, and the fixed part 6 and the movable part 7 are respectively provided with limiting grooves 10 for engaging with the annular flange 9. Specifically, as shown in the figure... Figures 1 to 3As shown, the snap-fit ​​between the annular flange 9 and the limiting groove 10 prevents the clamp 4 from detaching from the connector 5, thereby effectively improving the clamping stability of the clamp 4 and the connector 5, ensuring the connection stability between the connector 5 and the fixed part 6 and the movable part 7, and ensuring reliable use. It is worth noting that the connector 5 can be a screw rod as in the prior art, with the bottom of the connector 5 used for clamping by the clamp 4, and the annular flange 9 is the hexagonal nut on the screw rod; at the same time, after the clamp 4 clamps and limits the connector 5, the annular flange 9 can move and adjust along the extension direction of the limiting groove 10 within the limiting groove 10, so that the construction personnel can adjust the installation position of the clamp 4 relative to the connector 5 according to the actual situation, ensuring the stability of the subsequent installation of the secondary keel 3 and the ceiling panels.

[0033] In one embodiment, a groove 11 is formed on the side wall of the fixing part 6, and a boss 12 is formed on the side of the movable part 7 facing the fixing part 6 to slide and engage with the groove 11. An elastic member 8 is provided between the boss 12 and the bottom of the groove 11. Specifically, as shown... Figure 3 As shown, the sliding contact between the boss 12 and the groove 11 ensures the smoothness of the movement adjustment of the movable part 7 relative to the fixed part 6, and effectively prevents the fixed part 6 and the movable part 7 from rotating relative to each other and loosening the clamping limit on the secondary keel 3 or the connecting piece 5, ensuring reliable use. Furthermore, by placing the elastic element 8 between the bottom of the boss 12 and the groove 11, not only is the installation stability of the elastic element 8 ensured, but also the free movement of the elastic element 8 is prevented from affecting its use.

[0034] In one embodiment, the elastic element 8 is a spring, and there are multiple elastic elements 8, which are evenly and spaced apart along the extending direction of the groove 11. Specifically, as shown... Figure 2 and Figure 3 As shown, since the elastic element 8 is a spring, which has the characteristics of compact structure, easy material sourcing, and large elastic deformation, it can ensure the stable clamping of the connecting element 5 and the secondary keel 3 by the sleeve 4. Furthermore, multiple elastic elements 8 can connect the boss 12 at multiple points, thereby improving the connection stability between the movable seat and the fixed seat.

[0035] In one embodiment, the fixed part 6 and the movable part 7 are respectively provided with a slot 13 on their opposite sides, and the two sides of the secondary keel 3 are respectively formed with guide rails 14 along their extending direction to engage with the slot 13. Specifically, as shown in the figure Figure 2 and Figure 3As shown, the engagement between the guide rail 14 and the slot 13 prevents the secondary keel 3 from detaching from the clamp 4, thereby effectively improving the clamping stability of the clamp 4 and the secondary keel 3, ensuring the stable connection between the secondary keel 3 and the fixed part 6 and the movable part 7, and ensuring reliable use. It is worth noting that after the clamp 4 clamps and limits the secondary keel 3, it can move and adjust along the extension direction of the guide rail 14 on the secondary keel 3. This allows construction personnel to adjust the installation position of the clamp 4 or the secondary keel 3 according to the actual situation, ensuring the stable installation of the secondary keel 3 and the ceiling panels.

[0036] In one embodiment, specifically, as Figure 1 and Figure 2 As shown, multiple mounting holes 15 are evenly and spaced along the extension direction on the top surface of the main keel 2, and a through groove is provided on the bottom surface of the main keel 2. This allows construction personnel to adjust the installation position of the hanger 1 and connector 5 on the main keel 2 according to the actual situation, ensuring the stability of the connection between the main keel 2 and the hanger 1 and connector 5. At the same time, the through groove ensures that the bottom of the connector 5 extends into the clamp 4 to meet the clamping and limiting requirements of the clamp 4 on the connector 5. The structural design is simple and reasonable.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
