Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] See Figures 1 to 4 As shown, a snap-on spotlight that is easy to install and remove without damaging the ceiling includes a heat sink 1, a light source 2 fixed to the bottom surface of the heat sink, and a lens structure 3. The bottom surface of the heat sink is threaded with a front ring 4. In this embodiment, the heat sink is a conventional structure of the prior art, and the light source is a COB light source. In order to improve heat dissipation performance, thermal paste is applied to the substrates of the heat sink and the light source to improve thermal conductivity.

[0028] In this embodiment, the bottom surface of the radiator is integrally formed with a convex plate 5, and a middle ring 7 is rotatably connected to the convex plate by a screw 6; in actual application, the screw can be replaced by a bolt, pin or shaft.

[0029] In practical applications, the lower part of the outer wall of the middle ring is integrally formed with several C-shaped supports 8, and the C-shaped supports are rotatably connected with fasteners 9; in this embodiment, the number of C-shaped supports is three.

[0030] Furthermore, the bottom surface of the middle ring can be replaced with a lamp cup 10 spirally connected; during assembly, when it is installed, the bottom edge of the buckle is positioned against the top surface of the ceiling for limitation. When the external pulling force is greater than the friction between the C-shaped support and the buckle, the buckle rotates upward and falls off the top surface of the ceiling.

[0031] In this embodiment, the fastener includes a U-shaped support piece 91, a guide tilt piece 92 integrally formed on the bottom edge of the U-shaped support piece and bent outward, and an axial protrusion 93 integrally formed on the top of the symmetrical side wall of the U-shaped support piece; the guide tilt piece can mainly be positioned against the top surface of the ceiling for limiting when it is downward, and when the external force is large, the fastener can be rotated upward by the guide tilt piece, which is convenient for disassembly.

[0032] During assembly, the U-shaped support is located inside the C-shaped support, and the shaft protrusion is rotatably connected to the shaft hole of the C-shaped support.

[0033] In practical applications, the inner wall of the C-shaped support is provided with an arc-shaped protrusion 11. The height of the arc-shaped protrusion is relatively small. During assembly, the symmetrical edges of the U-shaped support plate abut against the arc-shaped protrusion. This is mainly used to increase the friction and resistance between the U-shaped support plate and the inner wall of the C-shaped support, ensuring that it can abut against the top surface of the ceiling and remain in place when there is no external force, making it less likely to loosen or fall off.

[0034] In this embodiment, the bottom end of the C-shaped support extends beyond the bottom surface of the middle ring, and the edge of the guide tilting plate protrudes from the surface of the C-shaped support. One side of the center line of the top surface of the middle ring is a tilt relief area 12; the screws are located at both ends of the tilt relief area. A drive power supply 13 is connected to the heat sink via wires, and the drive power supply is electrically connected to the light source. The tilt relief area primarily allows the middle ring to have a certain range of tilt adjustment space, ensuring the effectiveness of the tilt adjustment.

[0035] In this embodiment, the lens structure includes a lens housing 31 and a lens body 32. An L-shaped latching piece 33 is provided on the top surface of the lens housing. During assembly, the lens body is fixed inside the lens housing, and the L-shaped latching piece of the lens housing is positioned at the edge of the light source. This improves the convenience and effectiveness of lens structure installation.

[0036] This utility model has the following positive effects: Its structure is reasonably designed, featuring a C-shaped support on the central ring, with a rotatable fastener connected within the C-shaped support. During installation, the spotlight simply passes through the ceiling mounting hole, and the bottom edge of the fastener is pressed against the top surface of the ceiling, improving assembly convenience and preventing damage to the ceiling. Furthermore, during disassembly, the fastener flips upwards when the internal pushing force exceeds the resistance between the fastener and the C-shaped support, allowing it to detach from the ceiling surface for quick and easy removal from the mounting hole. This facilitates cleaning or light source replacement, reduces maintenance difficulty, and enhances disassembly convenience and effectiveness, making it highly adaptable.

[0037] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
