Description

Technical Field

[0001] This invention relates to the field of ceiling installation structure technology, specifically a ceiling installation structure for interior decoration. Background Technology

[0002] In interior decoration, ceiling installation is a common construction step. Traditional ceiling installation often uses expansion bolts to directly fix the hangers to the roof, and then suspends the ceiling panels through the hangers. This method has the following drawbacks: First, the ceiling panels and the suspension structure are usually fixedly connected, requiring complete removal for later maintenance of pipelines or replacement of light fixtures, which is cumbersome and can easily damage the ceiling surface. Second, the height of traditional hangers is not adjustable, requiring precise calculation of the hanger length during installation. If there is a deviation in the roof elevation or design changes, the hangers need to be recut, resulting in poor adaptability. Third, conventional threaded rods lack an effective self-locking braking structure after height adjustment. Under long-term load-bearing conditions, the threaded rods are prone to rotation due to vibration, causing the ceiling panels to sink, posing a safety hazard. Fourth, when adjusting the height, the suspended panels tend to rotate synchronously with the threaded rods, causing the ceiling panels to tilt, affecting installation accuracy and appearance flatness.

[0003] Therefore, there is an urgent need for a ceiling installation structure that is height-adjustable, brake-locked, anti-deflection, and easy to disassemble and reassemble later. Summary of the Invention

[0004] The purpose of this invention is to provide a ceiling installation structure for interior decoration, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 7 This invention provides a technical solution: a ceiling installation structure for interior decoration, including a mounting plate 1, with a ceiling plate 2 at the bottom of the mounting plate 1. The mounting plate 1 has a cross-shaped plate structure, with wing plates 103 fixed to the bottom surface at each of the four ends. Connecting screws 104 are screwed onto the surface of the wing plates 103, and the connecting screws 104 pass through the wing plates 103 and are screwed onto the side wall of the ceiling plate 2, thereby realizing a detachable connection between the ceiling plate 2 and the mounting plate 1, which facilitates later maintenance or replacement.

[0018] The surface of the hoisting plate 1 has a reserved opening 101, which is an "I"-shaped round opening. A bearing 102 is fixed inside the opening, and the inner ring of the bearing 102 is fitted onto the bottom end of the lead screw 3, providing stable support for the rotation of the lead screw 3. The lead screw 3 is rotatably connected inside the reserved opening 101, and a threaded sleeve 301 is screwed onto its top end. A fixing plate 302 is fixed to the top end of the threaded sleeve 301. The surface of the fixing plate 302 has multiple bolt holes. During installation, the fixing plate 302 is placed against the roof, and an expansion tube is passed through the bolt holes to fix the fixing plate 302 under the roof, thereby anchoring the entire hoisting structure to the roof.

[0019] A retaining ring 305 and a limiting sleeve 4 are sequentially fitted onto the bottom end of the lead screw 3. The inner ring surface of the retaining ring 305 is fixed to the rod body of the lead screw 3, and a rubber ring 306 is fixed to the outer ring surface. The rubber ring 306 is clamped between the retaining ring 305 and the inner wall of the reserved opening 101, generating elastic deformation and playing a preliminary limiting role in the axial position of the lead screw 3. Through holes 308 are opened on both sides of the retaining ring 305, and the rubber ring 306 covers one end of the through hole 308 to maintain the integrity of the elastic clamping.

[0020] The bottom end of the lead screw 3 has a threaded groove 307, which is a "T"-shaped circular groove. Through holes 308 on both sides of its top end pass through a retaining ring 305. A top support block 309 is inserted into the inner wall of the threaded groove 307. One end of the top support block 309 is fixed to the inner ring surface of the rubber ring 306, forming a linkage structure between the top support block 309 and the rubber ring 306. An anti-loosening screw 310 is threaded into the inside of the threaded groove 307. When the anti-loosening screw 310 is tightened, it pushes against the top support block 309, which in turn clamps the rubber ring 306 tightly against the inner wall of the pre-reserved opening 101. The friction between the rubber ring 306 and the inner wall of the pre-reserved opening 101 is used to brake and lock the lead screw 3, preventing it from rotating under the load of the suspended ceiling and ensuring structural safety.

[0021] The limiting sleeve 4 is a U-shaped circular plate, fitted onto the bottom end of the lead screw 3. A second anti-loosening screw 401 is screwed onto its surface, connecting to the bottom end of the lead screw 3 and axially fixing the limiting sleeve 4. A retaining cover 402 is fitted onto the bottom end of the limiting sleeve 4. A rubber ring 403 is fixed to the inner ring of the top of the retaining cover 402. The rubber ring 403 is clamped between the retaining cover 402 and the limiting sleeve 4, undergoing elastic deformation. This enhances the connection between the retaining cover 402 and the limiting sleeve 4, and also protects the second anti-loosening screw 401, preventing it from loosening due to vibration. Multiple levers 404 are also fixed to the bottom end of the limiting sleeve 4, allowing operators to rotate the limiting sleeve 4 by pressing the levers 404 with their fingers, assisting in adjusting the height of the lead screw 3.

[0022] A limiting ring 303 is fixedly fitted onto the outer wall of the threaded sleeve 301. Multiple through-holes 304 are formed on the surface of the limiting ring 303, and an anti-deviation traction tube 5 is inserted into each through-hole 304. The anti-deviation traction tube 5 passes through the corresponding through-hole 304, and its bottom end is fixed to the top surface of the lifting plate 1. The top ends of the multiple anti-deviation traction tubes 5 are fixed with the same connecting ring 501, which is fitted onto the threaded sleeve 301. The function of this structure is that when a finger is pressed against one side of the cover 402 and the screw rod 3 is rotated to adjust the height, the anti-deviation traction tube 5, through the connecting ring 501, restricts the threaded sleeve 301 from rotating synchronously with the screw rod 3, thereby preventing the lifting plate 1 from deflecting during adjustment and ensuring that the ceiling plate 2 remains horizontal at all times.

[0023] The installation and use process is as follows: First, place the fixing plate 302 against the roof surface. Anchor the fixing plate 302 to the roof surface using expansion tubes through bolt holes. Insert the bottom end of the lead screw 3 through the pre-drilled opening 101, so that the retaining ring 305 blocks the top of the pre-drilled opening 101, and the rubber ring 306 naturally clamps into the inner wall of the pre-drilled opening 101. Then, place the limiting sleeve 4 on the bottom end of the lead screw 3, tighten the anti-loosening screw 401 to fix the limiting sleeve 4, and then place the cover 402 on the bottom end of the limiting sleeve 4, using the elastic deformation of the rubber ring 403 to achieve blocking and fixation. Rotate the lead screw 3 by pressing a finger against the lever 404 or the cover 402. The lead screw 3 will rise or fall in the threaded sleeve 301. By adjusting the length of the lead screw 3 extending into the threaded sleeve 301, the height of the hoisting plate 1 and the ceiling plate 2 can be adjusted. During this process, the anti-deviation traction tube 5 passes through the limiting ring 303, effectively preventing the hoisting plate 1 from rotating. After the height is adjusted to the correct position, the anti-loosening screw 310 is screwed into the screw groove 307. The anti-loosening screw 310 pushes the top support block 309, and the top support block 309 drives the rubber ring 306 to press tightly against the side wall of the reserved opening 101, generating sufficient friction to brake and lock the screw 3, thus completing the installation and fixing of the ceiling.
