[0002] A ceiling light is a type of lamp that is installed inside a room. Because the upper part of the lamp is relatively flat and is installed close to the roof, it seems to be adsorbed on the roof, so it is called a ceiling light. It is commonly used in homes, offices, entertainment venues, etc. It is the main lighting equipment in the room, and its light sources include ordinary white bulbs, fluorescent lamps, high-intensity gas discharge lamps, halogen tungsten lamps, etc., while LED ceiling lights are ceiling lights that use LED lamp beads as the light source.

[0003] At present, the installation methods used for LED ceiling lamps are gluing, bolting or clamping. The above three methods all have certain disadvantages. For example, gluing will reduce the installation stability due to the quality of the glue, and both bolting and clamping have problems with the convenience of installation and disassembly. After research and study, we found that the threaded connection method of incandescent lamps is the fastest. For this reason, we apply the threaded connection method to the installation of LED ceiling lamps to achieve the purpose of improving installation efficiency. Utility Model Content

At this time, the installation of the LED ceiling lamp is completed, which is convenient and quick.

[0017] 2. The utility model provides a limit screw and a limit hole. After the LED ceiling lamp is installed, the knob is turned, and the knob will drive the second bevel gear to rotate through the synchronous shaft. The second bevel gear will then drive the first bevel gear to rotate through the meshing action. After the first bevel gear rotates, it will drive the limit screw to rotate through the telescopic shaft. After the limit screw rotates, it will move upward under the action of the threaded inner wall of the sleeve column until the limit screw moves into the limit hole.

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model and can not be understood as limiting the utility model.

[0025] The embodiments of the utility model will be described below according to the overall structure of the utility model.

[0026] A connecting structure of LED ceiling lamp, as shown in Figure 1-5 The bottom of top plate 1 is provided with LED ceiling lamp 2, and a threaded connection structure is arranged between top plate 1 and LED ceiling lamp 2. The threaded connection structure comprises mounting column 3 fixed at the bottom end of top plate 1, and sleeve column 4 sleeved outside mounting column 3 and fixed at the top end of LED ceiling lamp 2 is arranged on the outer side of mounting column 3. The outer wall of mounting column 3 is provided with threaded part 5, and the inner wall of sleeve column 4 is provided with threaded wall 6 matched with threaded part 5.

[0027] Further, the top end of sleeve column 4 in the embodiment is provided with limiting screw rod 7 extending from the inside of sleeve column 4 to the upper side of sleeve column 4, and limiting screw rod 7 is symmetrically arranged on both sides of sleeve column 4. The upper side of limiting screw rod 7 is provided with limiting hole 8 opened at the bottom end of top plate 1, and the hole diameter of limiting hole 8 is matched with the outer diameter of limiting screw rod 7.

[0028] In the above description, when LED ceiling lamp 2 and top plate 1 are installed through the threaded connection structure, the limiting of sleeve column 4 is realized by driving limiting screw rod 7 to move into limiting hole 8, so that the long-term stable connection state of LED ceiling lamp 2 is ensured, and the influence of the installation stability of LED ceiling lamp 2 caused by the displacement of sleeve column 4 due to external factors is avoided.

[0029] See also Figure 4 , a driving structure for driving the limit screw rod 7 to move is installed inside the sleeve column 4;

[0030] In the above description, the driving structure is provided to realize the driving of the limiting screw rod 7, so that the limiting of the sleeve column 4 can be completed quickly.

[0031] See also Figure 4-5 The driving structure includes a knob 11 mounted on the outer wall of the sleeve 4 and connected through a damping bearing, and the end of the knob 11 is fixedly connected to a synchronous shaft extending into the interior of the sleeve 4, the top of the first bevel gear 9 is synchronously connected to a telescopic shaft 12, and the end of the telescopic shaft 12 is fixedly connected to the bottom end of the limit screw 7;

[0032] In the above description, the driving structure is dominated by gear transmission, and is driven by the rotation of the knob 11 to achieve the driving of the limit screw 7.

[0033] See also Figure 5 The outer side of the limit screw 7 is located on the inner wall of the sleeve 4 and is provided with a threaded inner wall that is adapted to the thread of the outer wall of the limit screw 7;

[0034] In the above description, after the limiting screw rod 7 rotates, it will react with the threaded inner wall of the inner wall of the sleeve 4 and move, thereby assisting the movement of the limiting screw rod 7.

[0035] The working principle of the present invention is as follows: when installing the LED ceiling lamp 2, the sleeve column 4 is moved to the outside of the mounting column 3, and then the LED ceiling lamp 2 is rotated. At this time, under the action of the threaded portion 5 on the outer wall of the mounting column 3 and the threaded wall 6 on the inner wall of the sleeve column 4, the sleeve column 4 will move upward along the mounting column 3 until it moves to the limit position. At this time, the installation of the LED ceiling lamp 2 is completed, which is convenient and quick.

[0036] Furthermore, after the LED ceiling lamp 2 is installed, turn the knob 11, the knob 11 will drive the second bevel gear 10 to rotate through the synchronization shaft, and the second bevel gear 10 will then drive the first bevel gear 9 to rotate through the meshing action. After the first bevel gear 9 rotates, it will drive the limit screw 7 to rotate through the telescopic shaft 12. After the limit screw 7 rotates, it will move upward under the action of the threaded inner wall of the inner wall of the sleeve column 4 until the limit screw 7 moves to the limiting hole 8. At this time, the limit screw 7 will limit the sleeve column 4, thereby ensuring the stability of the connection state of the sleeve column 4, that is, ensuring the connection stability of the LED ceiling lamp 2 after installation.
