Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] like Figures 1 to 9As shown, a pre-embedded ceiling access structure includes a frame 1 and a cover plate 2. The frame 1 has an access port 5, and the cover plate 2 is movably installed on the frame 1 and used to seal the access port 5. The frame 1 is assembled by connecting rods 3 and corner connectors 4 for connecting adjacent connecting rods 3, which simplifies the production and installation process and reduces production costs. The connecting rods and corner connectors can be pre-produced and assembled on site, reducing the complexity of on-site processing.

[0021] This modular design allows the size and shape of the access panel to be flexibly adjusted according to actual needs. For example, depending on the size of the ceiling and the layout of the internal equipment, connecting rods 3 of different lengths and corner connectors 4 of different angles can be selected to create rectangular, square, or other shaped access panels.

[0022] Specifically, the connecting rod 3 and the corner connector 4 are provided with a matching connecting structure 6 and are spliced ​​together through the connecting structure 6.

[0023] The connecting structure 6 includes connecting grooves 301 at both ends of the connecting rod 3 and snap-fit ​​posts 401 at both ends of the corner connector 4. The connecting rod 3 and the corner connector 4 are connected by inserting the snap-fit ​​posts 401 into the connecting grooves 301.

[0024] After the snap-fit ​​post 401 is inserted into the connecting groove 301, it is pressed on the outside of the connecting groove 301 to make the wall of the connecting groove 301 recessed inward to form a positioning protrusion 302. The outer wall of the snap-fit ​​post 401 forms a positioning recess 402 through pressing. The positioning protrusion 302 and the corresponding positioning recess 402 strengthen the connection between the snap-fit ​​post 401 and the connecting groove 301, ensuring the firmness of the connection.

[0025] In this invention, in addition to snap-fit ​​and press-fit, other connection methods such as screws, rivets or welding can be used to connect the frame 1 and the cover plate 2 to further enhance the reliability of the connection.

[0026] Furthermore, the corner connector 4 includes a corner connector 403 located between the two end locking posts 401. The corner connector 403 includes a corner inner wall 404 located on one side of the cover plate 2 and a corner outer wall 405 located on the outside. A reinforcing rib 406 is provided between the corner inner wall 404 and the corner outer wall 405 to enhance the strength and stability of the corner connector and ensure the overall structural strength of the frame.

[0027] like Figure 10 As shown, the inner corner wall 404, the outer corner wall 405, and the corner connector 204 of the plate can all be designed as arc-shaped structures to make the edges of the frame 1 and the cover plate 2 fit more closely. At the same time, a reinforcing rib 406 is provided between the inner corner wall 404 and the outer corner wall 405 to enhance the strength and stability of the corner connector.

[0028] like Figures 1 to 9 As shown, when the ceiling access panel is quadrilateral, the inner corner wall 404 and the corner connector 204 can be set as an arc-shaped structure, and the outer corner wall 405 can be set as a right-angle structure. A reinforcing rib 406 is set between the right-angle outer corner wall 405 and the arc-shaped inner corner wall 404, which not only strengthens the connection between the outer corner wall 405 and the inner corner wall 404, but also enhances the strength and stability of the corner connector.

[0029] like Figure 11 As shown, when the ceiling access panel is quadrilateral, its inner corner wall 404, outer corner wall 405, and panel corner connector 204 can all be designed as right-angle structures.

[0030] Furthermore, the lower outer wall of the connecting rod 3 and the corner connector 4 is provided with an extension edge 7, and the extension edge 7 is provided with a through hole 8. After the ceiling inspection port is installed, the extension edge 7 is the bottom surface. After installation, the ceiling needs to be painted for beautification. The design of the through hole 8 increases the contact area between the lower surface of the extension edge 7 and the latex paint, and at the same time, it traps some latex paint into the through hole 8, making the bond between the lower surface of the extension edge 7 and the latex paint more firm and enhancing the overall aesthetics of the ceiling.

[0031] Furthermore, the cover plate 2 includes a plate body 201 and a plate body mounting assembly 202 installed on the outer ring of the plate body 201. The cover plate 2 is movably sealed to the inspection port 5 through the plate body mounting assembly 202.

[0032] The plate mounting assembly 202 includes a second connecting rod 203 and a plate corner connector 204 for connecting adjacent second connecting rods 203; The upper side of the outer wall of the second connecting rod 203 is provided with a protruding snap plate 205. The cover plate 2 is embedded and snapped into the inspection port 5. The lower surface of the protruding snap plate 205 is in contact with the upper surface of the connecting rod 3, and the outer wall of the second connecting rod 203 is in contact with the inner wall of the connecting rod 3.

[0033] Furthermore, the upper surface of the second connecting rod 203 is provided with a snap-fit ​​groove 206, and both ends of the plate corner connector 204 are provided with snap-fit ​​plates 207. The connection between the second connecting rod 203 and the plate corner connector 204 is completed by inserting the snap-fit ​​plates 207 into the snap-fit ​​groove 206. After the snap-fit ​​plates 207 are inserted into the snap-fit ​​groove 206, the connection between the snap-fit ​​plates 207 and the snap-fit ​​groove 206 is pressed and tightened on the upper side of the snap-fit ​​groove 206. The pressing method is the same as the pressing method of the snap-fit ​​post 401 and the connecting groove 301. The connection between the snap-fit ​​post 401 and the connecting groove 301 and the connection between the snap-fit ​​plates 207 and the snap-fit ​​groove 206 can be strengthened by simple pressing, which simplifies the production process and reduces production costs.

[0034] like Figures 1 to 9As shown in the figure, this is the first embodiment of the present invention. The connecting rod 3 and the corner connector 4 are spliced ​​together by the snap-fit ​​post 401 and the connecting groove 301 to form the frame 1. After the splicing is completed, the wall of the connecting groove 301 is pressed inward to form a positioning protrusion 302, and the outer wall of the snap-fit ​​post 401 is pressed to form a positioning recess 402, ensuring the firmness of the connection.

[0035] The cover plate 2 is assembled by inserting the corner connector 204 of the outer ring of the plate 201 into the snap-fit ​​plate 207, and by pressing and fastening the snap-fit ​​plate 207 to the snap-fit ​​groove 206.

[0036] Install the assembled frame 1 onto the ceiling, and insert the cover plate 2 into the access panel 5. At this point, the lower surface of the protruding snap-fit ​​plate 205 is in contact with the upper surface of the connecting rod 3, and the outer wall of the second connecting rod 203 is in contact with the inner wall of the connecting rod 3, completing the assembly of the frame 1 and the cover plate 2. After installation, the ceiling is painted for aesthetic purposes. The through-hole 8 design on the extended edge 7 increases the contact area between the lower surface of the extended edge 7 and the latex paint, while also holding some latex paint into the through-hole 8, making the bond between the lower surface of the extended edge 7 and the latex paint more secure and enhancing the overall aesthetics of the ceiling.

[0037] When maintenance is required, the cover plate 2 can be easily removed from the frame 1, exposing the access port 5, allowing operators to enter the ceiling for repairs. In the non-maintenance state, the cover plate 2 is movable to the access port 5 via the panel mounting assembly 202, ensuring the overall aesthetics and sealing of the ceiling.

[0038] This utility model reduces processing complexity, material waste, and resource utilization efficiency by splicing the connecting rod 3 and the corner connector 4. It also reduces production costs. At the same time, the splicing design allows the size and shape of the ceiling access panel to be flexibly adjusted according to actual needs, making it more widely applicable.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
