Description

Technical Field

[0001] This utility model relates to the field of ceiling fan lighting technology, and in particular to a ceiling fan lighting fixture that can be raised and hidden. Background Technology

[0002] Ceiling fan lights combine an electric fan and a light fixture into one unit, installed on the ceiling. They meet daily lighting needs while providing cooling and air circulation during hot seasons, effectively saving floor and wall space. Therefore, they are widely used in various indoor spaces such as homes, offices, and restaurants. With the continuous improvement of modern home aesthetics, the design of ceiling fan lights is also trending towards intelligence and simplicity. For example, the design of retractable and retractable fan blades allows the light fixture to maintain a clean appearance when the fan function is not in use. This also presents new challenges to the product's ease of installation and structural reliability.

[0003] In existing technology, ceiling fan blades are typically installed using bolts or screws. The typical mechanical structure involves a mounting bracket with threaded holes pre-installed on the motor disc or hub of the fan, with a corresponding through-hole at the base of each blade. During installation, the worker needs to precisely align the through-hole at the blade base with the threaded hole on the motor bracket, then pass the screw through the through-hole on the blade, and finally use a screwdriver or wrench to tighten the screw into the threaded hole of the bracket. Each blade usually requires two to three screws for secure fixing to ensure a stable connection.

[0004] However, this traditional screw-fastening installation method has significant problems such as cumbersome operation and low efficiency. Since the installation of ceiling fan lights involves working at height, installers typically need to stand on a ladder, holding the heavy fan blades with one hand to keep them aligned, while using the other to operate the small screws and specialized tightening tools. The entire process is strenuous and inconvenient. In this posture, screws are easily slipped and lost, not only wasting time but also creating safety hazards. To ensure safety, each screw must be fully tightened, a repetitive and tedious operation. This tool-dependent and complex installation method greatly reduces the ease of installing ceiling fan lights, is extremely unfriendly to non-professionals, and increases the labor intensity of skilled workers.

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a liftable and concealable ceiling fan light fixture, including a collection cover 1, which serves as the top cover of the light fixture and the mounting base for the concealment mechanism. An electric push rod 2 is fixedly connected inside the collection cover 1, providing linear driving force for lifting the entire fan light fixture. A connecting shell 3 is fixedly connected to the output end of the electric push rod 2, allowing the connecting shell to move along with the electric push rod, thereby driving the fan blades and the light fixture to rise and fall. A light fixture 4 is fixedly connected to the bottom of the connecting shell 3, providing illumination and being one of the core functions of the entire device. Fan blades 5 are provided at the top of the connecting shell 3, generating air convection and providing a fan function. A connecting component is provided between the fan blades 5 and the connecting shell 3, enabling quick, tool-free installation and disassembly of the fan blades and the main body.

[0033] The connecting assembly includes a mounting pin 7, which serves as the mounting shaft for the fan blade and the main body of the locking mechanism. The mounting pin 7 passes through the inside of the fan blade 5, connecting the mounting pin and the fan blade into a unit to be installed. The mounting pin 7 is slidably connected inside the connecting housing 3, allowing the mounting pin and fan blade to be inserted into the mounting hole of the connecting housing. The connecting housing 3 has a slot 6 inside, which serves as a fixed receiving slot for the locking mechanism, used to engage with a steel ball for locking. A steel ball 12 is provided inside the mounting pin 7, acting as a movable locking pin and a key component for achieving quick locking. The steel ball 12 engages with the slot 6, locking the mounting pin and the connecting housing axially, thus fixing the fan blade. A pull rod 8 is slidably connected inside the mounting pin 7, acting as an internal unlocking lever, controlling the retraction of the steel ball through its axial movement. A tapered column 11 is fixedly connected to the outer wall of the pull rod 8, serving as... The wedge-shaped block, used to control the radial position of the steel ball, has its outer wall of the cone 11 in contact with the steel ball 12. Its function is to convert the axial movement of the pull rod into the radial movement of the steel ball using the cone surface, thus controlling the extension or retraction of the steel ball. A reset assembly is provided on the outer wall of the pull rod 8. Its function is to ensure that the pull rod automatically returns to the locked position after the unlocking operation. The reset assembly includes a limiting plate 9, which serves as the force-bearing end face of the spring and a limiting element for the pull rod. The limiting plate 9 is fixedly connected to the outer wall of the pull rod 8, ensuring that the spring's thrust is effectively applied to the pull rod. A spring 10 is sleeved on the outer wall of the pull rod 8, providing a continuous reset thrust for the pull rod. One end of the spring 10 is fixedly connected inside the mounting pin 7, providing a fixed support point for the spring. The other end of the spring 10 is fixedly connected to the top of the limiting plate 9, continuously pushing the limiting plate, which in turn pushes the pull rod and the cone on it, ensuring that the cone always pushes the steel ball out to the locked position, maintaining the locked state.

[0034] Reference Figure 4 and Figure 5An adjusting rod 13 is fixedly connected to the top of the collection cover 1. This rod serves as the hanging rod for the fan light fixture, suspending the entire fixture and setting its installation distance from the ceiling. A slider 14 is slidably connected to the outer wall of the adjusting rod 13. This slider serves as a movable mounting base, allowing precise adjustment of the light fixture's suspension height by changing its position on the adjusting rod. An adjusting groove 17 is provided inside the slider 14, providing a lateral adjustment range for the bolts connecting to the ceiling. A connecting bolt 15 is located inside the slider 14, acting as a connector to link the slider to the mounting rod ultimately fixed to the ceiling. The bottom of the connecting bolt 15 is slidably connected inside the adjusting groove 17, allowing for fine-tuning of the installation point in the horizontal direction. The installation flexibility is increased by adapting to different spacing of the pre-drilled mounting holes on the ceiling. One end of the connecting bolt 15 is fixedly connected to the mounting rod 16, which allows the connecting bolt to be connected to the final load-bearing component. The mounting rod 16 is used to connect to the ceiling and serves as the final load-bearing fixing component, safely transferring the weight of the entire fan light fixture to the building structure. The slider 14 is internally threaded with a disc bolt 18, which serves as a locking device to fix the slider at any position on the adjusting rod. The bottom of the disc bolt 18 fits against the outer wall of the adjusting rod 13. When tightened, its end will press against the outer wall of the adjusting rod, and the friction generated will firmly lock the slider, thereby determining and fixing the final installation height.

[0035] Working principle: When using this retractable and concealable ceiling fan light fixture, firstly, when installing the fan blade 5, the fan blade 5 is placed on top of the connecting shell 3. Then, the mounting pin 7 is inserted into the connecting shell 3 after passing through the fan blade 5. Subsequently, the steel ball 12 and the slot 6 are engaged, and the mounting pin 7 fixes the fan blade 5 on the connecting shell 3. The steel ball 12 is supported by the cone column 11, which makes it stably engaged in the slot 6. The cone column 11 is limited in the mounting pin 7 by the pull rod 8, and is supported by the tension of the springs 10 on the upper and lower sides of the limiting plate 9, so that the cone column 11 can self-reset, which achieves the effect of facilitating the installation of the fan blade 5.

[0036] When installing the collection cover 1, first install the mounting rod 16 on the ceiling, then fix the connecting bolt 15 to the mounting rod 16, slide the bottom of the connecting bolt 15 into the adjusting groove 17 to connect with the slider 14, and then slide the slider 14 into the outer wall of the adjusting rod 13. When the slider 14 is adjusted to the position on the outer wall of the adjusting rod 13, screw the disc bolt 18 into the slider 14 to abut against the outer wall of the adjusting rod 13, thereby fixing the slider 14 and the adjusting rod 13, which achieves the effect of facilitating the installation of ceiling fan light fixtures.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
