[0031] Through the above arrangement, first, the number of clip assemblies is increased, improving the stability of the ceiling light installation; second, the clip assembly can switch states, in the first state, it is not necessary to use hands to maintain, which facilitates the installation of the ceiling light into the plasterboard 20, and after switching to the second state, the ceiling light is locked on the plasterboard 20.

[0032] ​​The ceiling lamp of the application is specifically used on a suspended ceiling with a gypsum board 20 or a wooden board as a material, and the gypsum board 20 is taken as an example for detailed description. The shell 3 of the ceiling lamp is basically in a circular structure, and the first limiting surface 4 is annular and extends along the outer periphery of the shell 3. When the ceiling lamp is installed, a circular hole matching the shell 3 is first opened on the gypsum board 20, there is a wire above the gypsum board 20, and the upper side of the shell 3 is provided with a wire connection port. After the wire is pulled out of the hole and connected to the wire connection port, the clamping piece assembly is in the first state, as shown in Figures 1 to 3 , the clamping piece 8 is retracted and basically horizontally abuts against the upper end of the limiting cylinder 5, the clamping piece 8 is staggered with the sliding groove 9 on the limiting cylinder 5, and the spring 7 is in a stretched state. The clamping piece assembly is stably maintained in the first state and does not need to be manually maintained in the state. The upper side of the shell 3 is embedded into the hole, the first limiting surface 4 is attached to the lower side of the gypsum board 20, and the clamping piece 8 reaches the upper side of the gypsum board 20 through the hole. The wrench is inserted into the insertion slot 10 upward through the operation hole 11, the insertion slot 10 is specifically hexagonal, the movable piece 6 is manually rotated by the wrench, the movable piece 6 rotates around the axis of the movable piece 6, the clamping piece 8 rotates with the movable piece 6, and when the clamping piece 8 rotates to the sliding groove 9, the movable piece 6 and the clamping piece 8 move downward under the downward elastic force of the spring 7. The clamping piece 8 is embedded into the sliding groove 9 and tightly presses the upper side of the gypsum board 20, and the clamping piece assembly is switched to the second state. In turn, the movable pieces 6 of the remaining clamping piece assemblies are rotated by the wrench, so that the clamping pieces 8 of all the clamping piece assemblies tightly press the upper side of the gypsum board 20. Finally, the clamping pieces 8 and the first limiting surface 4 clamp the upper and lower sides of the gypsum board 20 to lock the ceiling lamp on the gypsum board 20, and the installation of the ceiling lamp is completed.

[0033] As an implementation manner, the clamping piece assembly further comprises a locking piece 12, the movable piece 6 is provided with a mounting hole 13 penetrating therethrough, one end of the clamping piece 8 is a first extrusion end 81, the other end is a second extrusion end 82, and the clamping piece 8 is provided with a perforation 83. The clamping piece 8 is movably passed through the movable piece 6 through the mounting hole 13, the locking piece 12 is locked on the upper end of the movable piece 6 and penetrates the perforation 83. In the second state, the first extrusion end 81 of the clamping piece 8 abuts against the upper end of the limiting cylinder 5, and the second extrusion end 82 of the clamping piece 8 is downwardly inclined and tightly presses the gypsum board 20.

[0034] Through the above arrangement, when the clamping piece 8 tightly presses the gypsum board 20, the second extrusion end 82 of the clamping piece 8 can be downwardly rotated to enable the clamping piece 8 to clamp the gypsum board 20 with a relatively thin thickness.

[0035] In the first state of the clamping piece assembly of the application, the clamping piece 8 is basically horizontal, as shown in Figure 2 , the clamping piece 8 penetrates the mounting hole 13, the spring 7 pulls the movable piece 6 downward, and the movable piece 6 horizontally tightly presses the clamping piece 8 on the upper end of the limiting cylinder 5. At this time, as shown in Figure 3The clamping plate 8 is compressed inward, meaning it does not protrude from the side of the housing 3, allowing the housing 3 to be inserted upward into the hole of the plasterboard 20. The through hole 83 in this application is an elongated hole extending axially along the clamping plate 8. The width of the elongated hole is approximately equal to the locking member 12. The locking member 12 is specifically a screw, tightened onto the upper end of the movable member 6 and passing through the through hole 83 to prevent the clamping plate 8 from being pulled out. The mounting hole 13 is specifically a channel structure with flared ends and a constricted middle. The clamping plate 8 can rotate up and down around the middle of the mounting hole 13 as a fulcrum. The lateral width is approximately equal to the width of the clamping piece 8 to prevent it from wobbling left and right. When the movable part 6 is rotated by a wrench, the clamping piece 8 rotates with it. When the clamping piece 8 rotates to the slide groove 9, it extends radially outward along the housing 3. The second pressing end 82 of the clamping piece 8 faces away from the center of the housing 3. The movable part 6 moves downward along the limiting cylinder 5, causing the clamping piece 8 to be inserted into the slide groove 9. The upper end of the limiting cylinder 5 supports the first pressing end 81 of the clamping piece 8, causing the second pressing end 82 of the clamping piece 8 to move downward and press against the gypsum board 20. Figure 6 .

[0036] As one implementation, the clamping plate assembly also includes a fixing member 14 disposed above the limiting cylinder 5. The first pressing end 81 of the clamping plate 8 is disposed between the fixing member 14 and the limiting cylinder 5. One end of the fixing member 14 is fixedly connected to the upper end of the limiting cylinder 5. In the first state, the clamping plate 8 abuts against the fixing end of the fixing member 14.

[0037] The above settings facilitate the positioning of the clip 8, ensuring that the clip assembly is in the first state.

[0038] In this application, the fixing member 14 is integrally formed with the limiting cylinder 5, and the first pressing end 81 of the clamping piece 8 moves between the fixing member 14 and the upper end of the limiting cylinder 5, such as... Figure 1 In the first state of the clamping plate assembly, the first pressing end 81 of the clamping plate 8 abuts against the fixing end of the fixing member 14, and the fixing end of the fixing member 14 is used for positioning the clamping plate 8.

[0039] As one implementation, the clamping assembly also includes a fixing plate 15 fixedly connected to the lower end of the limiting cylinder 5. The fixing plate 15 is provided with a clearance hole 16 below the slot 10. The upper end of the spring 7 is fixedly connected to the lower end of the movable part 6, and the lower end of the spring 7 is fixedly connected to the fixing plate 15.

[0040] With the above settings, the clip assembly can be made into an independent module, which facilitates the assembly of the ceiling light.

[0041] The fixed plate 15 can be installed at the lower end of the limiting cylinder 5 by screws, and the fixed plate 15 and the limiting cylinder 5 form a frame structure capable of accommodating the movable piece 6 and the spring 7, so that the clamping piece assembly can be installed as a single module structure, and when the clamping piece assembly is installed, only the lower end of the limiting cylinder 5 needs to be fixed on the upper side of the shell 3 by screws. A avoiding hole 16 is separately formed on the fixed plate 15 and corresponds to the operation hole 11 on the shell 3, so that a wrench can be inserted into the slot 10 through the operation hole 11 and the avoiding hole 16.

[0042] As an implementation manner, an annular protrusion 17 extending upward is arranged around the avoiding hole 16, and the lower end of the spring 7 is sleeved on the annular protrusion 17.

[0043] Through the above arrangement, the stability of the spring 7 is increased, and the left and right shaking of the lower end of the spring 7 is prevented.
