[0002] The steel connection mechanism for suspended ceilings is a standardized load-bearing and fixing component constructed from steel. Made of high-strength steel through stamping, welding, or casting processes, it possesses characteristics of resistance to deformation, corrosion, and high load-bearing capacity. Its modular design achieves a stable connection between the ceiling panels and the building structure, distributing the load to the main frame and adapting to the height adjustment needs of different spaces. This mechanism is widely used in large-span public buildings such as commercial complexes, convention centers, and transportation hubs, as well as in industrial plants, cleanrooms, and other scenarios requiring high structural stability. It can be used with various ceiling materials such as mineral wool boards, aluminum panels, or metal grilles to achieve rapid installation, long-term use, and fire and moisture resistance. The existing suspension rods are fixed to the ceiling with nuts. Vibration and gravity can cause the nuts at the bottom to loosen and fall off. The stability of the fixation is poor, which can easily cause the ceiling to loosen and fall off, posing a serious safety hazard. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a steel connection mechanism for ceilings, which effectively solves the problem that the nuts at the bottom of the existing hangers will loosen and fall off due to vibration and gravity after they are fixed to the ceiling by nuts, resulting in poor fixing stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a steel connection mechanism for suspended ceilings, including a suspension rod, a connecting plate fixedly installed at the top of the suspension rod, a support base fixedly installed at the bottom of the suspension rod, two expansion sleeves symmetrically arranged on both sides below the support base, a fixed cylinder fixedly installed in the middle of the bottom of the support base, the fixed cylinder being a hollow cylinder with an open top, a threaded sleeve on the surface of the suspension rod, an internal thread on the inner wall of the threaded sleeve, an external thread on the outer wall of the lower part of the suspension rod, the threaded sleeve being movably installed on the surface of the suspension rod through the internal and external threads, and an installation groove being provided inside the lower end of the suspension rod; The lower end of the threaded sleeve is equipped with a transmission component, which is connected to two expansion sleeves. The bottom of the two expansion sleeves is fixedly installed with a limit plate. When the threaded sleeve rotates and moves, it can drive the two expansion sleeves to expand and fix the ceiling through the transmission component, and the two limit plates can limit and block it.

[0005] Preferably, the transmission assembly includes a movable ring disposed below the threaded sleeve, and the movable ring is sleeved on the surface of the rod. A slip ring is fixedly installed at the lower end of the threaded sleeve through a connecting ring. A ring groove is formed at the top of the movable ring, and the slip ring is slidably installed inside the ring groove.

[0006] Preferably, the lower end of the boom has two symmetrical upper openings, a support arm is fixedly installed inside the movable ring, and the support arm is inserted between the two upper openings. A push rod is fixedly installed in the middle of the bottom of the support arm, and the push rod is movably inserted between the support seat and the fixed cylinder.

[0007] Preferably, the lower end of the push rod extends into the interior of the fixed cylinder and is fixedly mounted with a support frame. Both sides of the fixed cylinder have lower openings. Both ends of the support frame are rotatably mounted with transmission rods. The lower ends of the transmission rods extend through the two lower openings to the outside of the fixed cylinder. The lower ends of the two transmission rods are rotatably connected to the two expansion sleeves through a rotary joint.

[0008] Preferably, each of the expansion sleeves has a slider fixedly installed on its top, and the support base has grooves on both sides of its lower surface, with the two sliders slidably installed inside the two grooves.

[0009] Preferably, a sliding rod is fixedly installed on the lower part of the inner wall of the expansion sleeve, and sliding sleeves are fixedly installed on both sides of the lower end of the fixed cylinder, with the two sliding rods movably inserted into the two sliding sleeves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator inserts the two expansion sleeves below the suspension rod into the connection hole of the ceiling and makes the two limiting plates pass through the connection hole; then, the operator rotates the threaded sleeve to rotate and move downward along the suspension rod. When the threaded sleeve rotates and moves downward, it drives the slip ring to slide in the ring groove through the connecting ring, and at the same time pushes the moving ring to move downward, so that the threaded sleeve will not drive the moving ring to rotate. When the moving ring moves downward, it drives the support frame to move downward through the support arm and the push rod. When the support frame moves downward, two transmission rods push two expansion sleeves to move in opposite directions. When the two expansion sleeves move in opposite directions, they drive two sliders to slide in two sliding grooves, and at the same time drive two sliding rods to slide in two sliding sleeves, thus ensuring the stability of the two expansion sleeves when they move. When the two expansion sleeves move in opposite directions, they expand inward and are fixed in the connection hole of the ceiling, and are simultaneously blocked and limited by two limit plates, thus enabling quick and convenient installation of the ceiling. This allows the hanger to quickly and easily install the ceiling securely, eliminating the need for a nut fastening design, thereby preventing the ceiling from loosening and slipping.

The bottom of the two expansion sleeves 4 is fixedly installed with a limit plate 22. When the threaded sleeve 2 rotates and moves, it can drive the two expansion sleeves 4 to expand and fix the ceiling through the transmission assembly, and the two limit plates 22 can limit and block it. Each of the expansion sleeves 4 has a slider 18 fixedly installed on its top. Both sides of the lower surface of the support base 5 have grooves 19. The two sliders 18 are slidably installed inside the two grooves 19, so that the two sliders 18 can slide within the two grooves 19 to limit the movement trajectory of the upper ends of the two expansion sleeves 4. The lower part of the inner wall of the expansion sleeve 4 has a slide rod 20 fixedly installed. Both sides of the lower end of the fixed cylinder 3 have a slide sleeve 21 fixedly installed. The two slide rods 20 are movably inserted into the two slide sleeves 21, so that the two slide rods 20 can slide within the two slide sleeves 21 to limit the movement trajectory of the lower ends of the two expansion sleeves 4.

[0015] In use, the operator inserts the two expansion sleeves 4 below the hanger rod 1 into the connection holes of the ceiling, and makes the two limiting plates 22 pass through the connection holes. Then, the operator rotates the threaded sleeve 2 to rotate downward along the hanger rod 1. When the threaded sleeve 2 rotates downward, it pushes the two expansion sleeves 4 to move in opposite directions through the transmission component. When the two expansion sleeves 4 move in opposite directions, they drive the two sliders 18 to slide in the two sliding grooves 19, and at the same time drive the two sliding rods 20 to slide in the two sliding sleeves 21, thus ensuring the stability of the two expansion sleeves 4 when moving. When the two expansion sleeves 4 move in opposite directions, they will expand inward and be fixed in the connection holes of the ceiling, and at the same time, they will be blocked and limited by the two limiting plates 22, thus quickly and conveniently installing the ceiling. This allows the hanger rod 1 to quickly and conveniently and securely install the ceiling, eliminating the need for a nut fastening design, thereby preventing the ceiling from loosening and slipping.

[0016] The transmission assembly includes a movable ring 8 disposed below the threaded sleeve 2, and the movable ring 8 is sleeved on the surface of the rod 1, so that the movable ring 8 can move along the surface of the rod 1.

Two upper openings 7 are symmetrically opened on the lower end surface of the boom 1. A support arm 12 is fixedly installed inside the movable ring 8, and the support arm 12 is inserted between the two upper openings 7, so that the two support arms 12 can move along the two upper openings 7. A push rod 13 is fixedly installed in the middle of the bottom of the support arm 12. The push rod 13 is movably inserted between the support base 5 and the fixed cylinder 3, so that the push rod 13 can move inside the mounting groove 6 and the fixed cylinder 3.

[0017] The operator rotates the threaded sleeve 2 and moves it downward along the boom 1. When the threaded sleeve 2 rotates downward, it drives the slip ring 10 to slide in the ring groove 11 through the connecting ring 9, and at the same time pushes the moving ring 8 downward, so that the threaded sleeve 2 will not drive the moving ring 8 to rotate. When the moving ring 8 moves downward, it drives the push rod 13 to move downward through the support arm 12.

[0018] The lower end of the push rod 13 extends into the interior of the fixed cylinder 3 and is fixedly mounted with a support frame 14. Both sides of the fixed cylinder 3 have lower openings 16. Both ends of the support frame 14 are rotatably mounted with transmission rods 15. The lower ends of the transmission rods 15 extend through the two lower openings 16 to the outside of the fixed cylinder 3. The lower ends of the two transmission rods 15 are rotatably connected to the two expansion sleeves 4 through a rotating joint 17. When the two transmission rods 15 move down, they can push the two expansion sleeves 4 to move in opposite directions.

[0019] When the push rod 13 moves down, it drives the support frame 14 to move down. When the support frame 14 moves down, it pushes the two expansion sleeves 4 to move in opposite directions through the two transmission rods 15. When the two expansion sleeves 4 move in opposite directions, they will expand inward and be fixed in the connection hole of the ceiling. At the same time, they will be blocked and limited by the two limit plates 22, so as to quickly and conveniently install the ceiling.
