Description

Technical Field

[0001] This utility model relates to the field of ceiling light technology, and in particular to a plug-in LED ceiling light structure. Background Technology

[0002] A ceiling light is a type of lighting fixture. As the name suggests, it is called a ceiling light because the top of the fixture is relatively flat and the bottom is completely flush with the ceiling during installation. A ceiling light generally consists of a mounting plate fixed to the ceiling, a light body mounted on the mounting plate, and an LED ceiling light cover fixed to the mounting plate. The light body can use ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, LEDs, etc.

[0003] In the prior art, such as the utility model patent with publication number CN212565503U, a plug-in LED ceiling light structure is disclosed. Addressing the problem that existing LED ceiling light covers are difficult to disassemble, leading to inconvenience in component replacement, the following solution is proposed: It includes an LED ceiling light housing and an LED ceiling light cover. The LED ceiling light housing is movably fitted onto the outside of the LED ceiling light cover. Connecting grooves are formed on both inner walls of the LED ceiling light housing, with open bottoms on both grooves. Connecting plates are fixedly installed on the top of both sides of the LED ceiling light cover, and the two connecting plates are movably connected to their corresponding connecting grooves. Horizontal grooves are formed on one inner wall of each of the two connecting grooves, and wedge-shaped plates are slidably installed within each horizontal groove. This utility model facilitates the disassembly and installation of the LED ceiling light cover, thereby facilitating the replacement of internal components. Furthermore, the installation stability of the cover is high, thus improving its safety in use.

[0004] However, in actual use, it was found that when disassembling the lampshade of the above-mentioned ceiling light, because the contact limit part is located at the upper shell, the lampshade will fall due to gravity when the upper limit part is released. At this time, another operator is needed to assist, which is obviously quite troublesome. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plug-in LED ceiling light structure. This ceiling light structure utilizes the positioning function of hollow strips and rectangular slots to facilitate installation. In addition, the release limit part is installed inside the lower lamp cover, so that only a single operator needs to complete the overall disassembly operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plug-in LED ceiling light structure includes an upper housing and a lower lampshade; a connecting mechanism comprising two rectangular strips symmetrically fixedly connected to the top of the upper housing, each rectangular strip having a rectangular slot at its lower end; two hollow strips symmetrically fixedly connected to the upper end of the lower lampshade, each hollow strip having a rectangular cavity inside; the upper ends of each hollow strip extending into the rectangular slots; a sliding plate that can slide left and right within each hollow strip; the opposite sides of each sliding plate being elastically connected to the inner wall of the corresponding hollow strip via multiple springs; wedge-shaped blocks fixedly connected to the opposite sides of each sliding plate; a first rectangular opening on the inner wall of the opposite side of each hollow strip; and a second rectangular opening on the inner wall of the opposite side of each rectangular slot; and a disassembly mechanism that cooperates with the connecting mechanism.

[0008] Preferably, the opposite sides of the two wedge-shaped blocks each have a first rectangular opening and a second rectangular opening.

[0009] Preferably, the inclined surfaces of both wedge-shaped blocks face upwards.

[0010] Preferably, the inner top of the upper housing is provided with a plurality of mounting holes.

[0011] Preferably, the lower lampshade has hidden grooves on both sides.

[0012] Preferably, the disassembly mechanism includes two pull bars fixedly connected to opposite sides of the two sliding plates, the opposite sides of the two pull bars penetrating the inner wall of the corresponding hollow bar, and the opposite sides of the two pull bars extending into the corresponding hidden groove.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] By combining rectangular slots with hollow strips, and using a wedge-shaped locking mechanism with springs, the lamps can be quickly installed and securely locked, greatly improving installation efficiency and stability. Meanwhile, the disassembly mechanism allows users to easily unlock and disassemble the lamps without the need for complicated tools. A single operator can operate the mechanism, reducing maintenance costs. In addition, the lamps are kept aesthetically pleasing. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A plug-in LED ceiling light structure includes an upper housing 1 and a lower lampshade 3. The upper housing 1 has multiple mounting holes 2 installed on its inner top. The upper housing 1 can be installed on the roof through the mounting holes 2. The lower lampshade 3 has hidden grooves 13 on both sides. With the hidden grooves 13, the subsequent disassembly parts are all located in the hidden grooves 13, which makes the actual aesthetics better.

[0021] The system also includes a connecting mechanism, which comprises two rectangular bars 5 symmetrically fixedly connected to the top of the upper housing 1. Each of the two rectangular bars 5 has a rectangular slot 6 at its lower end. Two hollow bars 4 are symmetrically fixedly connected to the upper end of the lower lampshade 3. The inner cavities of the two hollow bars 4 are rectangular, and their upper ends extend into the rectangular slots 6. Each of the two hollow bars 4 has a sliding plate 7 that can slide left and right. The opposite sides of the two sliding plates 7 are elastically connected to the inner walls of the corresponding hollow bars 4 via multiple springs 8. Wedge-shaped blocks 11 are fixedly connected to the opposite sides of the two sliding plates 7. The inner walls of the opposite sides of the two hollow bars 4 have a first rectangular opening 9, and the inner walls of the opposite sides of the two rectangular slots 6 have a second rectangular opening 10. The opposite sides of the two wedge-shaped blocks 11 pass through the corresponding first rectangular opening 9 and second rectangular opening 10. The inclined surfaces of the two wedge-shaped blocks 11 face upwards. This design facilitates the installation process.

[0022] It also includes a disassembly mechanism, which works in conjunction with the connection mechanism. The disassembly mechanism includes two pull bars 12 that are fixedly connected to the opposite sides of the two sliding plates 7. The opposite sides of the two pull bars 12 penetrate the inner wall of the corresponding hollow bar 4, and the opposite sides of the two pull bars 12 extend into the corresponding hidden groove 13. That is, the inner walls of the opposite sides of the two hidden grooves 13 are provided with through holes, and each pull bar 12 penetrates the corresponding through hole.

[0023] In this utility model, firstly, the upper housing 1 is accurately positioned and fixed on the roof through multiple mounting holes 2 on its inner top. At this time, the upper housing 1 is in a stable installation state, providing a foundation for subsequent assembly work. Next, the hollow strip 4 of the lower lampshade 3 is aligned with the rectangular slot 6 of the upper housing 1. Since the hollow strip 4 is rectangular, it matches the shape of the rectangular slot 6, so the hollow strip 4 can be smoothly inserted into the rectangular slot 6 to achieve positioning and insertion connection. During the process of the hollow strip 4 being fully inserted into the rectangular slot 6, the sliding plate 7 inside the hollow strip 4 and the wedge-shaped locking block 11 on it are squeezed by the inner wall of the rectangular slot 6, and the spring 8 is compressed as a result. When the wedge-shaped locking block 11 reaches the alignment position of the first rectangular opening 9 and the second rectangular opening 10, the spring 8 is released, pushing the sliding plate 7 and the wedge-shaped locking block 11 outward, so that they can pass through the second rectangular opening 10 and be locked in it, forming a stable locking state. At this time, the lower lampshade 3 is firmly connected to the upper housing 1, completing the entire installation process.

[0024] When disassembly is required, first, locate the corresponding pull bar 12 in the hidden slots 13 on both sides of the lower lamp cover 3. Hold the pull bar 12 and pull it away from the center of the lamp. This action will overcome the elasticity of the spring 8 and drive the sliding plate 7 and the wedge-shaped block 11 to move into the hollow bar 4. As the wedge-shaped block 11 gradually disengages from the second rectangular opening 10, the locking state is released. At this time, use this to maintain the action and move the lower lamp cover 3 down. The lower lamp cover 3 can be easily pulled out of the rectangular slot 6 to complete the disassembly process. A single worker can complete the entire operation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
