DETAILED DESCRIPTION Example

[0030] A pre-assembled step-down plate supporting connection and fixing assembly provided in this embodiment includes a fixed plate unit 1 arranged on a high-position plate a, a connecting plate unit 2 arranged on a step-down plate b and connected to the fixed plate unit 1, and a hanging plate unit 3 arranged on the step-down plate b and connected to the fixed plate unit 1 and the connecting plate unit 2 at both ends.

[0031] In this embodiment, the high-position plate a is an installation keel, and its height can be adjusted by a hanger and connected to the ceiling. The lower end of the step-down plate b is used to install a low-position plate, i.e., a hanging plate. In the actual installation process, the fixed plate unit 1 can be pre-installed on the high-position plate a in the factory, and the connecting plate unit 2 can be installed on the step-down plate b. Then, after the high-position plate a is fixedly installed on the ceiling at the construction site, the step-down plate b is lifted to the target position, and then the two ends of the hanging plate unit 3 are respectively plugged into the fixed plate unit 1 and the connecting plate unit 2 to complete the installation of the step-down plate b.

[0032] Compared with the traditional ceiling structure, the present device has at least the following advantages: first, the structure realizes modular assembly and installation, most of the structure can be prefabricated during factory production, and only nailing is required when installing the high-position plate a during on-site assembly, and the plug-in and hanging installation of the step-down plate b can be completed in one step, which makes the installation convenient and quick, saving the labor cost of on-site installation; second, the structure also has the fault tolerance space for fine-tuning the step-down plate b, which improves the fault tolerance rate during the installation process and reduces the requirements for the installation process; third, it is easy to disassemble. Compared with the disassembly steps in the comparative documents, the disassembly action of the present structure is greatly reduced, and the step-down plate b can be replaced with only one disassembly action; fourth, the structure also plays the role of closing the edge of the plate, which solves the problem of the splicing gap and improves the aesthetics of the ceiling.

[0033] As attached Figure 1 , 2 As shown, the fixing plate unit 1 includes a U-shaped fixing plate 101 arranged on the high-position plate a, a mounting hole 102 arranged on the side of the U-shaped fixing plate 101 close to the high-position plate a and used to connect the connecting plate unit 2, a first elastic strip 103 arranged on the inner wall of the U-shaped fixing plate 101 and clamped and fixed to the hanging plate unit 3 by extrusion, and a first fixing screw hole 104 arranged on the U-shaped fixing plate 101 and used to install a fixing screw.

[0034] In this embodiment, the opening of the U-shaped fixing plate 101 is located at the side end of the step-down plate b, and the fixing plate near the side end of the step-down plate b extends to the outside of the high-position plate a. At the same time, the mounting hole 102 is also located on the outside of the high-position plate a to facilitate the installation of the connecting plate unit 2 and the hanging plate unit 3. There are at least two first elastic strips 103, which are respectively arranged on the upper and lower inner walls of the U-shaped fixing plate 101. The material of the first elastic strip 103 can be selected from existing elastic rubber; the first fixing screw hole 104 is used to install fixing screws, and the prefabricated installation of the fixing plate unit 1 on the high-position plate a is completed in the factory.

[0035] As attached Figure 1 , 3 As shown, the connecting plate unit 2 includes a main plate 201 arranged on the step-down plate b, a connecting column 202 arranged at the end of the main plate 201 and connected to the U-shaped fixing plate 101 by plugging into the mounting hole 102, an inclined plate 203 arranged at the end of the main plate 201 away from the connecting column 202, a first vertical plate 204 arranged at the end of the inclined plate 203 and used for connecting to the hanging plate unit 3, and a second fixing screw hole 205 arranged on the main plate 201 and used for installing a fixing screw.

[0036] In this embodiment, the connecting columns 202 are equidistantly distributed on the upper surface of the main plate 201, and correspond one-to-one with the positions of the mounting holes 102, ensuring that the U-shaped fixing plate 101 is tightly connected to the main plate 201 without displacement, and the second fixing screw holes 205 are used to install fixing screws to complete the prefabricated installation of the connecting plate unit 2 fixed on the step-down plate b in the factory; in this embodiment, the main plate 201 is close to the step-down plate b, the inclined plate 203 is inclined outward and forms an L-shaped structure with the first vertical plate 204, and the gap between the L-shaped structure and the step-down plate b is the installation control for installing the hanging plate unit 3. Such a design can completely hide the connecting gap between the hanging plate unit 3 and the connecting plate unit 2, thereby improving the aesthetic effect.

[0037] As attached Figure 1 , 4 As shown, the hanging plate unit 3 includes a hanging plate body 301, a first extending horizontal plate 302 arranged at the end of the hanging plate body 301, a limiting inclined plate 303 arranged at the end of the first extending horizontal plate 302, a first plug-in plate 304 arranged at the end of the limiting inclined plate 303 and fixed by extrusion with the first elastic strip 103, a second extending horizontal plate 305 arranged on the side of the hanging plate body 301 away from the first extending horizontal plate 302, a second vertical plate 306 arranged at the end of the second extending horizontal plate 305 and connected to the surface of the step-down plate b, and a second elastic strip 307 arranged on the second vertical plate 306 and clamping and fixing the first vertical plate 204 by extrusion.

[0038] In the present embodiment, the Z-shaped structure composed of the first extended transverse plate 302, the limiting inclined plate 303, and the first plug-in plate 304 is used to complete the connection between the hanging plate unit 3 and the fixed plate unit 1, wherein the thickness of the first plug-in plate 304 is greater than the distance between the two first elastic strips 103 to ensure that the first plug-in plate 304 is fully clamped and fixed after being inserted between the two first elastic strips 103, and the limiting inclined plate 303 and the first extended transverse plate 302 are used to provide the connecting column 202 with a suitable insertion space, so that the main plate 201 can have a certain adjustment range in height, and at the same time, the connecting column 202 that is pushed upward has the effect of preventing the inclined limiting inclined plate 303 from retreating outward, thereby preventing the first plug-in plate 304 from slipping outward, thereby enhancing the connection between the hanging plate unit 3 and the fixed plate unit 1. The second extended horizontal plate 305, the second vertical plate 306, the second elastic strip 307 and the hanging plate body 301 form a U-shaped structure, which is used to connect with the above-mentioned inclined plate 203 and the first vertical plate 204 to form an L-shaped structure. In this embodiment, the second elastic strip 307 is distributed on the second vertical plate 306 and on the inner wall of the hanging plate body 301 corresponding to the second vertical plate 306. The distance between the two second elastic strips 307 is also smaller than the thickness of the first vertical plate 204 to ensure that the first vertical plate 204 is fully clamped and fixed; the second extended horizontal plate 305 is close to the step-down plate b, so the hanging plate body 301, the second extended horizontal plate 305 and the second vertical plate 306 form a trimming structure, which effectively hides the connection between the hanging plate unit 3 and the connecting plate unit 2, greatly improving the aesthetic effect.

[0039] In this embodiment, the structure of the hanging plate unit 3 has at least the following advantages: first, the installation method of the hanging plate unit 3 is plug-in fixing, which can be completed in one step during installation and removal, reducing the difficulty of installation and saving installation time; second, the upper end of the structure of the hanging plate unit 3 is plugged with the fixed plate unit 1, and at the same time, the connecting plate unit 2 limits the plug-in position of the hanging plate unit 3 on the fixed plate unit 1 in the horizontal direction, so the plug-in structure between the hanging plate unit 3 and the fixed plate unit 1 is strong and stable; third, the lower end of the hanging plate unit 3 is not only connected to the connecting plate unit 2, but also connected to the fixing plate unit 1. 2 is plugged in and has the function of carrying the connecting plate unit 2 upward, and has a good fixing effect on the connecting plate unit 2 in the vertical direction, so as to ensure that the connecting plate unit 2 will not fall due to gravity. At the same time, the plug-in structure between the connecting plate unit 2 and the fixed plate unit 1 completes the limited fixation of the connecting plate unit 2 in the horizontal direction, so that the installation strength and stability of the connecting plate unit 2 fixed by the plug-in structure are large; fourthly, the connection between the hanging plate unit 3 and the fixed plate unit 1 and the connecting plate unit 2 is perfectly hidden, and the connection seam cannot be seen by the naked eye, which greatly improves the aesthetic effect.

[0040] As attached Figure 5-7 As shown, the structure of this embodiment also includes a connecting member unit 4 arranged between two adjacent U-shaped fixing plates 101 and used to clamp the first elastic strip 103, including a connecting fixing plate 401 arranged between the two adjacent U-shaped fixing plates 101, grooves 402 arranged on both sides of the connecting fixing plate 401 and respectively engaged with the two U-shaped fixing plates 101, four circular holes 403 respectively arranged on both sides of the connecting fixing plate 401, and a fixing rod 404 arranged on each of the circular holes 403 and used to press and fix the first elastic strip 103.

[0041] In this embodiment, the connector unit 4 has at least the following effects: first, it strengthens the connection between the two adjacent U-shaped fixing plates 101, reduces the splicing gap, and makes all the U-shaped fixing plates 101 form a horizontal plane after splicing, thereby improving the aesthetic effect; second, it converts the first elastic strip 103 into a detachable installation mode, and when the first elastic strip 103 ages, hardens or loses elasticity due to long-term use, it can be replaced in time or regularly to ensure the connection strength between the hanging plate unit 3 and the connecting plate unit 2 and the fixed plate unit 1, and at the same time, it is more convenient for the overall disassembly and replacement of the hanging plate unit 3 and the connecting plate unit 2.

[0042] In this embodiment, the Figure 5The figure shows a half structure of a connecting member unit 4, and the other half structure is the same as the figure, specifically: the two grooves 402 are opened at the upper end of the connecting fixing plate 401, in an I-shape, and the two grooves 402 are respectively engaged and fixed on the upper long plates of the two adjacent U-shaped fixing plates 101. The circular holes 403 in this embodiment are 4 in total, and are divided into two groups in the form of a groove edge perpendicular to the groove 402, with 2 circular holes 403 in each group, and the distance between the two circular holes 403 in each group is greater than the distance between the two first elastic strips 103 on the inner wall of the same U-shaped fixing plate 101, so that after the two fixing rods 404 are respectively inserted into the two circular holes 403 in one group, each fixing rod 404 has a pressing effect on each first elastic strip 103, and two groups of circular holes are provided to fix the two ends of each first elastic strip 103. When the first elastic strip 103 needs to be replaced, the fixing rod 404 can be pulled out.

[0043] As attached Figure 8 As shown, the connecting member unit 4 further includes a channel 405 disposed on the connecting fixing plate 401 and connecting the groove 402 and the circular hole 403 , a fixed shaft 406 disposed on the channel 405 , and an eccentric wheel 407 disposed on the fixed shaft 406 .

[0044] In this embodiment, the diameter of the eccentric wheel 407 is greater than the length of the channel 405. The effect of this is that when the upper long plate of the U-shaped fixing plate 101 is inserted into the groove 402, the upper long plate of the U-shaped fixing plate 101 will push the eccentric wheel 407 to rotate until the eccentric wheel 407 protrudes from the surface of the circular hole 403. In this way, when the fixing rod 404 is inserted, the fixing rod will push the eccentric wheel 407 in the opposite direction to make the long radius side of the eccentric wheel 407 move toward the U-shaped fixing plate 101. However, since the diameter of the eccentric wheel 407 is longer than the length of the channel 405, the eccentric wheel 407 will eventually be in a balanced state with both end surfaces slightly protruding from the surfaces of the groove 402 and the circular hole 403, and has a certain squeezing and fixing effect on the upper long plate of the U-shaped fixing plate 101 and the fixing rod 404 in the groove 402 and the circular hole 403, thereby improving the connection strength between the connector unit 4 and the fixing plate unit 1.

[0045] In this embodiment, the connecting member unit 4 is also arranged between two adjacent second vertical plates 306 and also plays the role of clamping the second elastic strip 307. Its structure is the same as that of the connecting member unit 4 arranged between two adjacent U-shaped fixing plates 101, so it is not repeated here.

[0046] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
