[0040] like Figures 1 to 10 As shown, the present application discloses a ceiling corner cover installation structure, comprising:

[0041] A panel frame 101, wherein corner cover mounting portions 102 are provided at four azimuth angles of the panel frame 101, a first mounting opening 1010 for mounting an air inlet grille is provided at a central position of the panel frame 101, and a corner cover guide fixing portion is provided on the corner cover mounting portion 102 in a direction toward the central position of the first mounting opening 1010;

[0042] The corner cover plate 200 comprises a corner cover plate body 201 , on which a connecting ear plate 202 is arranged. The connecting ear plate 202 can be slid relative to the guide fixing portion of the corner cover plate along a direction toward the center position of the first mounting port 1010 and then fixed.

[0043] The ceiling corner cover installation structure described in the present application is provided with a corner cover guide fixing portion on the panel frame 101 in the direction toward the center of the first installation port 1010, and correspondingly, a connecting ear plate 202 capable of relative sliding and fixing along the corner cover guide fixing portion is provided on the corner cover 200, so as to achieve a more secure fixation of the corner cover, reduce the need for additional space, and make the corner cover 200 and the panel frame 101 relatively tight at the connection, avoid the formation of an unsightly black hole at the connection, and make the appearance more neat and compact. Compared with the traditional single-clip fixing method, this design reduces the possibility of loosening, improves the effect and reliability of corner cover assembly, and enhances the user experience.

[0044] The ceiling machine corner cover installation structure described in the present application improves the firmness of the corner cover installation, reduces the space requirement, improves the appearance, and enhances the performance and user experience of the ceiling machine.

[0045] As a preferred example of the present application, the corner cover plate guiding and fixing portion includes a second connecting boss 1012, on which a guide rib 1013 and a first connecting hole 1014 are arranged, and the connecting ear plate 202 includes a first connecting plate 2021 and a second connecting plate 2022, the first connecting plate 2021 is connected as a whole with the corner cover plate body 201, and a second connecting hole 2023 is arranged on the second connecting plate 2022, and the second connecting plate 2022 can move toward the center position of the first mounting port 1010 under the action of the guide rib 1013, and the second connecting hole 2023 is correspondingly connected to the first connecting hole 1014.

[0046] As a preferred example of the present application, two guide ribs 1013 are provided, and the first connecting hole 1014 is located between the two guide ribs 1013 .

[0047] This arrangement provides more fixing points and connecting elements, thereby enhancing the fixing performance of the corner cover plate and preventing the corner cover plate from loosening or falling off during use, while also ensuring the smoothness and stability of the sliding guide of the connecting ear plate 202 along the guide fixing portion of the corner cover plate.

[0048] As a preferred example of the present application, a third limiting rib 1015 is provided on the second connection boss 1012, and a limiting clamping rib 2024 is provided on the second connection plate 2022. The limiting clamping rib 2024 is limited after sliding over the third limiting rib 1015. As an example of the present application, the front side of the limiting clamping rib 2024 along the sliding forward direction of the corner cover plate 200 is arranged in an inclined shape, and the rear side of the limiting clamping rib 2024 along the sliding forward direction of the corner cover plate 200 is arranged in a vertical shape. This arrangement facilitates the connecting ear plate 202 to smoothly slide past the third limiting rib 1015 and be limited when sliding. At this time, the second connecting hole 2023 is arranged correspondingly to the first connecting hole 1014, which facilitates the assembly and fastening of the corner cover plate 200 and the panel frame 101. The corresponding arrangement of the third limiting rib 1015 and the limiting clamping rib 2024 allows the connecting ear plate 202 to be naturally fixed after sliding into place, avoiding its movement in the opposite direction of the sliding installation and causing the connecting hole to be misaligned.

[0049] As a preferred example of the present application, the second connection hole 2023 is set in an open shape, and the second connection hole 2023 includes a limiting connection portion 20231 and a guide opening portion 20232, and the guide opening portion 20232 is set in an opening shape that gradually increases in a direction away from the limiting connection portion 20231. This setting makes the connection and fixation of the second connection hole 2023 and the first connection hole 1014 smoother and easier, while avoiding installation failure due to processing errors, improving installation efficiency, and ensuring that the corner cover 200 is stably connected to the panel frame 101.

[0050] As a preferred example of the present application, reinforcing ribs 2025 are arranged in the circumferential direction of the position-limiting connection portion 20231, and the reinforcing ribs 2025 are arranged on the surface of the second connection plate 2022 away from the first connection plate 2021. This arrangement enhances the structural strength of the position-limiting connection portion 20231, while reducing damage caused by fatigue and stress, thereby improving the durability and service life of the connection portion on the corner cover plate 200.

[0051] As a preferred example of the present application, the corner cover mounting portion 102 is provided with a second limiting rib 109 at a corner position close to the first mounting opening 1010, and a second mounting opening 1011 is provided on the second limiting rib 109.

[0052] This arrangement places the corner cover plate guiding fixing portion outside the corner cover plate mounting portion 102, and plays a role of limiting and positioning during the installation process through the combination of the second limiting rib 109 and the second mounting opening 1011, thereby ensuring the precise positioning of the connection and preventing deviation or incorrect installation during the assembly process. The structure is compact and at the same time ensures that the four corner cover plates 200 can be installed quickly and reliably, reducing the difference in design of the corner cover plate mounting portion 102 and the corner cover plates 200, and simplifying manufacturing and assembly.

[0053] As a preferred example of the present application, a first limiting retaining rib 104 is provided on the corner cover mounting portion 102, and correspondingly, a fourth limiting retaining rib 203 is provided on the corner cover body 201, and the fourth limiting retaining rib 203 is stopped and limited by the first limiting retaining rib 104 when the corner cover 200 slides into place. As an example of the present application, the first limiting retaining rib 104 and the fourth limiting retaining rib 203 are designed in a multi-section bending shape, which ensures that the corner cover body 201 is accurately positioned and limited to the required position during the installation process, thereby improving the efficiency of the installation. At the same time, the multi-section bending structure can absorb or disperse the force from impact and vibration to a certain extent, and can maintain the safety of the connection even when there is vibration or impact in the environment.

[0054] As a preferred example of the present application, a plug-in slot 107 is provided on the corner cover mounting portion 102, and the opening direction of the plug-in slot 107 is provided along the sliding direction of the corner cover 200. Correspondingly, a guide buckle 204 is provided on the corner cover 200, and the guide buckle 204 can be inserted into the plug-in slot 107 for sliding limit. As an example of the present application, three plug-in slots 107 are provided, which are respectively located at three corner positions other than the second connecting boss 1012 provided on the corner cover mounting portion 102. Correspondingly, three guide buckles 204 are also provided, and the three guide buckles 204 are all provided in the sliding direction of the corner cover 200.

[0055] This arrangement further improves the stability and reliability of the connection between the corner cover plate 200 and the panel frame 101, while ensuring that the three end corners of the corner cover plate 200 are tightly connected, preventing the appearance of black holes in the connection, and ensuring the consistency and aesthetics of the overall appearance of the ceiling machine.

[0056] As a preferred example of the present application, the guide buckle 204 includes a connecting portion 2041 and a guiding portion 2042, and a guiding rib 2043 is provided on the side of the guiding portion 2042 away from the connecting portion 2041. This arrangement makes the connection between the guide buckle 204 and the plug-in slot 107 a line-surface connection, reduces the sliding resistance, and improves the smoothness of the sliding assembly connection between the corner cover 200 and the panel frame 101.

[0057] As a preferred example of the present application, a first reinforcing rib 105 is provided on a side of the first limiting rib 104 away from the second connecting boss 1012, and a first opening 106 is formed in the area between the first reinforcing rib 105 and the first limiting rib 104, wherein the height of the first reinforcing rib 105 is lower than the height of the first limiting rib 104. This arrangement ensures the reliability of the fourth limiting rib 203 on the angle cover body 201 and the first limiting rib 104 when they are installed, and at the same time, a first opening 106 for inserting a hand or a screwdriver for operation is formed at the position of the angle cover installation portion 102.
