Description

Technical Field

[0001] This invention belongs to the field of fan light technology, and specifically relates to a fan light with quick blade installation. Background Technology

[0002] Traditional fan lights typically use screws or clips to fix the fan blades, but both methods have limitations. While screws provide structural stability, installation and disassembly are cumbersome, requiring tools to tighten or loosen each blade individually, increasing maintenance time and operational difficulty, especially posing safety hazards when working at heights. Clips eliminate the need for tools, improving efficiency, but repeated use can lead to fatigue, breakage, or loosening of the clip structure, reducing the reliability of the fan blade connection and affecting overall safety. Conventional solutions include optimizing screw materials and design, and strengthening clips, but these often increase costs and structural complexity, and may even introduce new points of failure due to over-reliance on local structures, failing to fundamentally resolve the conflict between convenience and reliability. Therefore, we aim to design a fan light with a novel structure to address this problem. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a fan light with quick blade installation, thereby resolving the problems mentioned in the background section.

[0004] This invention is achieved through the following technical solution: a fan light with quick blade installation, comprising: a turntable, wherein the side wall of the turntable has multiple slots radially inward for inserting fan blades, an installation platform is installed on the top of the turntable, and the lower surface of the installation platform is provided with multiple fan-shaped installation areas, each of the fan-shaped installation areas on the lower surface of the installation platform is provided with multiple sets of rectangularly distributed fixing seats for installing fixing covers, a trapezoidal push block is slidably installed on the rear side of each fixing cover for unlocking, and a slider is slidably installed on the left and right sides of each fixing cover, and the two sliders are connected to the left and right ends of a locking spring, and multiple ring-shaped adjustment components are provided on the lower inner side of the turntable for pushing the trapezoidal push block to unlock the fan blades, and multiple circularly distributed pressing components are installed on the top of the turntable.

[0005] As a preferred embodiment, the fixing base has a number 8-shaped structure, with a screw hole at one end and a positioning pin hole at the other end. Each of the fan-shaped mounting areas is provided with four screw holes and four positioning pin holes distributed in a rectangular structure.

[0006] The fixed cover is provided with four rectangular positioning pins on the side near the fixed base. The distribution position, length and diameter of the four positioning pins are matched with the distribution position, depth and inner diameter of the four positioning pin holes.

[0007] The fixed cover has a bolt for installing the fixed cover on its left front side, left rear side, right front side and right rear side respectively. The four bolts are distributed in a rectangular structure and match the distribution position and size of the four screw holes.

[0008] In a preferred embodiment, the slider includes a hook and a sliding part. The hook is arranged in a Z-shape, and the end of the hook near the locking spring is provided with a hooking hole for hooking with the locking spring. The end of the sliding part near the cover plate is provided with a connecting plate, and the connecting plate is slidably connected to the fixed cover.

[0009] A positioning plate is provided on the side of the connecting plate near the trapezoidal push block. An inclined abutment is provided between the positioning plate and the connecting plate. The abutment slides against the inclined side surface of the trapezoidal push block, and the inclined surfaces of the two are at the same angle.

[0010] The hook is fixedly connected to the sliding part on the side near the sliding part by screws. A limiting groove is provided laterally between the two fixing seats on one side of each fan-shaped installation area to guide and limit the connection between the upper side of the hook and the locking spring. In actual use, the locking spring is pre-stretched. The locking spring is a tension spring. Pre-stretching can keep the sliders on both sides in a taut state. When the inner end of the fan blade is inserted into the fixing cover, the buckle blocks on both sides can be in a tightened state after being inserted into the buckle groove, thereby preventing the fan blade from detaching when it is running at high speed after installation.

[0011] In a preferred embodiment, the middle of the two screw holes on the left side and the middle of the two screw holes on the right side of the fixing cover are respectively recessed to form a guide groove for sliding installation of the sliding part and guiding it.

[0012] Within each of the aforementioned sector-shaped installation areas, a recess is formed between the two left-side fixing seats and between the two right-side fixing seats, with the cross-sectional structure and dimensions of the recess being matched with the structure and dimensions of one end of the hook-and-loop locking spring.

[0013] In a preferred embodiment, a limiting protrusion is provided in the middle of the surface of the fixed cover near the trapezoidal push block. The limiting protrusion has a T-shaped structure, and a guide groove is provided in the middle of the surface of the trapezoidal push block near the fixed cover.

[0014] The guide groove is slidably connected to the vertical part of the limiting protrusion, the end of the trapezoidal push block away from the inclined surface is movably abutted against the horizontal part of the limiting protrusion, the upper side of the fixed cover is recessed downward to form an insertion groove, and the insertion groove is inserted into the part of the fan blade inserted into the turntable.

[0015] Two positioning protrusions are provided at one end of the insertion slot near the inside of the turntable, and two positioning grooves are provided at the end of the fan blade that is inserted into the insertion slot.

[0016] In a preferred embodiment, the structure, size and distribution of the two positioning grooves and the two positioning protrusions are matched, and the upper middle side of the fan blade with the two positioning grooves is recessed downward to form a track groove.

[0017] The inner end of the track groove passes through the middle of one end of the fan blade with two positioning grooves, and the outer end of the track groove is connected to the concave spherical groove. The center line of the track groove is collinear with the center line of the spherical groove. The left and right sides of the end of the fan blade inserted into the turntable are respectively provided with an undercut groove.

[0018] The sliding part is provided with an inverted block on the upper side of the fixed cover. The structure and size of the inverted block are matched with the structure and size of the inverted groove. The end of the fan blade inserted into the turntable does not directly contact the locking spring.

[0019] In a preferred embodiment, a convex plate is provided on the lower side of the trapezoidal push block, through which a threaded nut is installed. The adjusting assembly includes a bushing, which is fixed to the upper side of the inner wall of the turntable. The bushing is rotatably connected to the outer end of the lead screw. The inner end of the lead screw is threadedly connected to the convex plate through the threaded nut. A limiting rod is installed transversely through the inner end of the lead screw to limit the threaded nut and the convex plate.

[0020] In a preferred embodiment, the clamping assembly includes a mounting cylinder, the bottom of which is fixedly connected to the upper surface of the turntable, and an upper limit plate is fixedly attached to the top of the inner part of the mounting cylinder;

[0021] A compression spring is installed inside the mounting cylinder. The upper end of the compression spring is fixedly connected to the upper limit plate, and a lower limit plate is movably installed at the bottom of the mounting cylinder.

[0022] The lower limit plate is in movable contact with the lower end of the compression spring. The middle of the upper side of the lower limit plate is splined to the lower end of the rotating rod and supports its up and down sliding. The upper diameter of the rotating rod is larger than the lower diameter, and the lower part of the rotating rod is placed inside the compression spring.

[0023] In a preferred embodiment, the upper part of the rotating rod extends upward through the upper limit plate and the top of the mounting cylinder and is rotatably connected to the top of the mounting cylinder. The upper side wall of the rotating rod is provided with a handle in an inverted L-shaped structure.

[0024] The lower end of the handle extends into the top of the mounting cylinder. The top of the mounting cylinder is recessed downward to form a quarter-circle arc groove. Magnetic blocks are fixed to the inner walls of both ends of the arc groove for temporary magnetic fixation of the lower part of the handle.

[0025] A connecting rod is provided at the lower middle of the lower limit plate. The lower end of the rotating rod extends to the upper interior of the connecting rod. The upper side of the connecting rod passes downward through the top of the mounting cylinder and is slidably connected to it. A guide wheel is installed at the lower end of the connecting rod. Half of the outer wall of the guide wheel is wrapped with a rubber sleeve. The cross-sectional width of the guide wheel matches the cross-sectional width of the track groove. In actual use, the length of the guide wheel's circumference is generally the same as the length of the track groove. When the guide wheel initially contacts the track groove, the middle half of the guide wheel without the rubber sleeve contacts the starting position of the track groove. After the guide wheel rotates halfway, the guide wheel reaches the spherical groove. At this time, the part with the rubber sleeve abuts against the inner wall of the spherical groove. When the compression spring contacts the guide wheel and the track groove, it is pushed up and compressed. The reaction force it provides allows the guide wheel to continuously squeeze the inner end of the fan blade. The design of the guide wheel makes it not very difficult to insert the inner end of the fan blade.

[0026] After adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. By setting up an installation platform, trapezoidal push block, fixed plate cover, slider and fan blade, the plug-in installation method allows the fan blade to be installed without the need for bolts or external installation tools. Stable fixed installation can be completed simply by pushing and inserting. This effectively solves the contradiction between convenience and reliability that conventional optimization of screw material and design and enhancement of buckle strength cannot fundamentally solve, thus improving the convenience and efficiency of fan blade installation.

[0027] If the fan blades need to be disassembled, cleaned, or replaced, the user first rotates the locking component counterclockwise by 90 degrees, and then uses an external tool to rotate the lead screw located on the side of the turntable. After rotating a certain number of times, the retaining block completely disengages from the retaining groove. At this point, the fan blades can be pulled out, which makes the disassembly and assembly of the fan blades very convenient.

[0028] 2. By setting the clamping component, the guide wheel reaches the spherical groove. At this time, the part with the rubber sleeve abuts against the inner wall of the spherical groove. Then, rotate the handle 90 degrees clockwise, so that the guide wheel rotates 90 degrees in the spherical groove, that is, perpendicular to the track groove. Under the action of the spherical groove and the track groove, plus the abutment of the side of the guide wheel with the rubber sleeve, and the continuous reaction force provided by the compression spring, the fixation degree of the inner end of the fan blade can be improved, ensuring the stability of the fan blade when rotating at high speed. The magnetic block located on the inner wall of the arc groove can prevent the handle from moving without the action of external force, which would cause the guide wheel to deflect.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] As the first embodiment of the present invention:

[0041] Please see Figures 1 to 8 A fan light with quick blade installation includes: a turntable 1, with multiple slots radially inwardly opened on the side wall of the turntable 1 for inserting fan blades 9; an installation platform 2 installed on the top of the turntable 1; multiple fan-shaped installation areas provided on the lower surface of the installation platform 2; multiple sets of rectangularly distributed fixing seats provided in each fan-shaped installation area on the lower surface of the installation platform 2 for installing fixing covers 5; a trapezoidal push block 7 slidably installed on the rear side of each fixing cover 5 for unlocking; a slider 12 slidably installed on the left and right sides of each fixing cover 5, and the two sliders 12 are connected to the left and right ends of a locking spring 13; multiple ring-shaped adjustment components 15 are provided on the lower inner side of the turntable 1 for pushing the trapezoidal push block 7 to unlock the fan blades 9; and multiple circularly distributed pressing components 17 are installed on the top of the turntable 1.

[0042] The mounting base has a number 8-shaped structure, with a screw hole 3 at one end and a positioning pin hole 4 at the other end. Each sector-shaped mounting area has four screw holes 3 and four positioning pin holes 4 arranged in a rectangular structure.

[0043] The fixed cover 5 is provided with four rectangular positioning pins on the side near the fixed base. The distribution position, length and diameter of the four positioning pins are matched with the distribution position, depth and inner diameter of the four positioning pin holes 4.

[0044] The left front, left rear, right front and right rear sides of the fixing cover 5 are each fixed with a bolt for installing the fixing cover 5. The four bolts are distributed in a rectangular structure and match the distribution position and size of the four screw holes 3.

[0045] The slider 12 includes a hook 121 and a sliding part 122. The hook 121 is arranged in a Z-shaped structure, and the end of the hook 121 near the locking spring 13 is provided with a hook hole for hooking with the locking spring 13. The end of the sliding part 122 near the cover plate is provided with a connecting plate 123, and the connecting plate 123 is slidably connected to the fixed cover 5.

[0046] A positioning plate 124 is provided on the side of the connecting plate 123 near the trapezoidal push block 7. An inclined abutment is provided between the positioning plate 124 and the connecting plate 123. The abutment slides against the inclined side surface of the trapezoidal push block 7, and the inclined surfaces of the two are at the same angle.

[0047] The side of the hook 121 near the sliding part 122 is fixedly connected to the sliding part 122 by screws. A limiting groove 14 is provided horizontally between the two fixing seats on one side of each fan-shaped installation area to guide and limit the connection between the upper side of the hook 121 and the locking spring 13. In actual use, the locking spring 13 is pre-stretched. The locking spring 13 is a tension spring. Pre-stretching can keep the sliders 12 on both sides in a taut state. When the inner end of the fan blade 9 is inserted into the fixing cover 5, the undercut blocks on the sliders 12 on both sides can be in a tightened state after being inserted into the undercut groove 11, thereby preventing the fan blade 9 from coming off when it is running at high speed after installation.

[0048] The two screw holes 3 on the left side of the fixed cover 5 and the two screw holes 3 on the right side are recessed inward to form a guide groove for sliding installation of the sliding part 122 and for guiding it.

[0049] In each sector-shaped installation area, the two left-side fixing seats and the two right-side fixing seats are recessed upwards to form a clearance groove. The cross-sectional structure and dimensions of the clearance groove match the structure and dimensions of one end of the hook 121 connecting to the locking spring 13.

[0050] A limiting protrusion 6 is provided in the middle of the surface of the fixed cover 5 near the trapezoidal push block 7. The limiting protrusion 6 has a T-shaped structure. A guide groove is provided in the middle of the surface of the trapezoidal push block 7 near the fixed cover 5.

[0051] The guide groove and the vertical part of the limiting protrusion 6 are slidably connected. The end of the trapezoidal push block 7 away from the inclined surface is in contact with the horizontal part of the limiting protrusion 6. The upper side of the fixed cover 5 is recessed downward to form an insertion groove. The insertion groove is inserted into the part of the fan blade 9 inserted into the turntable 1.

[0052] Two positioning protrusions 8 are provided at one end of the insertion slot near the inside of the turntable 1, and two positioning slots 10 are provided at the end of the fan blade 9 that is inserted into the insertion slot.

[0053] The structure, size and distribution of the two positioning grooves 10 and the two positioning protrusions 8 are matched. The fan blade 9 is provided with a track groove formed by the downward indentation of the upper middle side of one end of the two positioning grooves 10.

[0054] The inner end of the track groove passes through the middle of one end of the fan blade 9 and has two positioning grooves 10. The outer end of the track groove is connected to the concave spherical groove 16. The center line of the track groove is collinear with the center line of the spherical groove 16. The left and right sides of the end of the fan blade 9 inserted into the turntable 1 are respectively provided with an inverted groove 11.

[0055] The sliding part 122 is provided with an inverted block on the upper part of the fixed cover 5. The structure and size of the inverted block are matched with the structure and size of the inverted groove 11. The end of the fan blade 9 inserted into the turntable 1 does not directly contact the locking spring 13.

[0056] A convex plate is provided on the lower side of the trapezoidal push block 7, through which a threaded nut is installed. The adjusting assembly 15 includes a bushing 151, which is fixed on the upper side of the inner wall of the turntable 1. The bushing 151 is rotatably connected to the outer end of the lead screw 152. The inner end of the lead screw 152 is threadedly connected to the convex plate through the threaded nut. A limiting rod 153 is installed transversely through the inner end of the lead screw 152 to limit the threaded nut and the convex plate.

[0057] Specifically, by setting up the installation platform 2, trapezoidal push block 7, fixed cover, slider 12 and fan blade 9, in actual use, if it is necessary to install the fan blade 9, the user aligns the inner end of the fan blade 9 with the slot on the turntable 1 and pushes it in. During this process, the inner end of the fan blade 9 gradually enters the insertion slot on the fixed cover 5 (in actual use, the bottom opening of the insertion slot is designed to facilitate the upper part of the fixed cover 5 to be set to the bottom of the insertion slot). When it contacts the sliders 12 on both sides of the fixed cover 5, the undercut block on the sliding part 122 of the slider 12 slides against the side of the inner end of the fan blade 9. Since the locking spring 13 is in a pre-stretched state, the undercut blocks on both sides of the slider 12 are in a state of being tightened by the compression spring 174. With the pushing and squeezing of the inner end of the fan blade 9, the compression spring 174 is stretched again, and it generates a greater reaction force to pull the two sliders 12 in opposite directions.

[0058] When the two undercut blocks reach the undercut groove 11, they quickly engage with the undercut groove 11 under the action of the locking spring 13. This allows the two sliders 12 to lock and fix the inner end of the fan blade 9 through the undercut groove 11 and the undercut blocks. Simultaneously, the positioning groove 10 on the inner end of the fan blade 9 engages with the positioning protrusion 8 inside the insertion groove, preventing the fan blade 9 from wobbling after locking and fixing, thus improving the stability of the fan blade 9 during use. When the fan blade 9 is rotating at high speed, the centrifugal force on the fan blade 9 pulls the sliders 12 on both sides. Due to the design of the undercut blocks and the undercut groove 11, this allows the two sliders to... Block 12 is snapped into the inner end of the fan blade 9 with an inverted fixing structure, and the two sliders 12 are limited by the stretched locking spring 13, which can ensure that the fan blade 9 will not be affected by centrifugal force and detach when rotating at high speed, thus ensuring the safety of the fan blade 9 at high speed. The plug-in installation method means that the fan blade 9 does not need to use bolts or external installation tools during installation. It can be stably fixed by simply pushing it in. This effectively solves the contradiction between convenience and reliability that conventional optimization of screw materials and design and enhancement of buckle strength cannot fundamentally solve, thus improving the installation convenience and efficiency of the fan blade 9.

[0059] If the fan blade 9 needs to be disassembled, cleaned, or replaced, the user should first rotate the locking assembly 17 counterclockwise by 90 degrees, and then use an external tool to rotate the lead screw 152 located on the side of the turntable 1 (in actual use, the outer end of the lead screw 152 is provided with a head that can be used with a screwdriver or a socket wrench; during installation, the lead screw 152 is in its initial position and will not affect the normal movement of the slider 12). When the lead screw 152 rotates, it pushes the convex plate to move, and at the same time, the trapezoidal push block 7 moves accordingly. Because the connecting plate 123 is located on the side near the trapezoidal push block 7... There is a positioning plate 124, and an inclined abutment is provided between the positioning plate 124 and the connecting plate 123. The abutment slides against the side inclined surface of the trapezoidal push block 7, and the inclined surfaces of the two are at the same angle. As the trapezoidal push block 7 moves, it pushes the abutment that slides against it through its side inclined surface, thereby causing the sliders 12 on both sides to be gradually pushed open and move in opposite directions. This further causes the undercut block that is locked in the undercut groove 11 to gradually disengage. After rotating a certain number of times, the undercut block completely disengages from the undercut groove 11. At this time, it is only necessary to pull out the fan blade 9, which makes the disassembly and assembly of the fan blade 9 very convenient.

[0060] As a second embodiment of the present invention:

[0061] Please see Figures 1 to 8 The clamping assembly 17 includes a mounting cylinder 175, the bottom of which is fixedly connected to the upper surface of the turntable 1, and an upper limit plate 179 is fixedly installed at the top inside the mounting cylinder 175.

[0062] A compression spring 174 is installed inside the mounting cylinder 175. The upper end of the compression spring 174 is fixedly connected to the upper limit plate 179. A lower limit plate 173 is movably installed at the bottom of the mounting cylinder 175.

[0063] The lower limit plate 173 is in movable contact with the lower end of the compression spring 174. The middle of the upper side of the lower limit plate 173 is splinedly connected to the lower end of the rotating rod 176 and supports its up and down sliding. The upper diameter of the rotating rod 176 is larger than the lower diameter, and the lower part of the rotating rod 176 is placed inside the compression spring 174.

[0064] The upper part of the rotating rod 176 extends upward through the upper limit plate 179 and the top of the mounting cylinder 175 and is rotatably connected to the top of the mounting cylinder 175. The upper side wall of the rotating rod 176 is provided with a handle 177 in an inverted L-shaped structure.

[0065] The lower end of the handle 177 extends into the top of the mounting cylinder 175. The top of the mounting cylinder 175 is recessed downward to form a quarter-circle arc groove 178. Magnetic blocks are fixed to the inner walls of both ends of the arc groove 178 for temporarily magnetically fixing the lower part of the handle 177.

[0066] A connecting rod 171 is provided at the lower middle of the lower limit plate 173. The lower end of the rotating rod 176 extends to the upper interior of the connecting rod 171. The upper side of the connecting rod 171 penetrates downward through the top of the mounting cylinder 175 and is slidably connected to it. A guide wheel 172 is installed at the lower end of the connecting rod 171. Half of the outer wall of the guide wheel 172 is wrapped and fixed with a rubber sleeve. The cross-sectional width of the guide wheel 172 matches the cross-sectional width of the track groove. In actual use, the general circumference of the guide wheel 172 is the same as the length of the track groove. When the guide wheel 172 initially connects... When the guide wheel 172 touches the track groove, the middle half of the guide wheel 172 without the rubber sleeve contacts the starting end of the track groove. After the guide wheel 172 rotates halfway, the guide wheel 172 reaches the spherical groove 16. At this time, the part with the rubber sleeve abuts against the inner wall of the spherical groove 16. The compression spring 174 is pushed up and compressed when the guide wheel 172 contacts the track groove. The reaction force it provides allows the guide wheel 172 to continuously squeeze the inner end of the fan blade 9. The design of the guide wheel 172 makes it less difficult to insert the inner end of the fan blade 9.

[0067] Based on the first embodiment described above, further, by setting the clamping component 17, in actual use, when installing the fan blade 9, the guide wheel 172 is in the initial position, that is, the guide wheel 172 is parallel to the track groove. As the inner end of the fan blade 9 continues to enter, the initial end of the track groove contacts the guide wheel 172. At this time, after the guide wheel 172 contacts the track groove, under the squeezing action of the inner end of the fan blade 9, the guide wheel 172 pushes the connecting rod 171 and the lower limit plate 173 to move upward and squeeze the compression spring 174 inside the mounting cylinder 175. Since the upper middle of the lower limit plate 173 is connected to the spline of the lower end of the rotating rod 176 and supports its up and down sliding, the upward movement of the lower limit plate 173 will not affect the rotating rod 176. Under the restoring potential energy of the compression spring 174, the pressure of the guide wheel 172 on the inner end of the fan blade 9 increases, and it can continuously squeeze the inner end of the fan blade 9.

[0068] The guide wheel 172 makes it easy to insert the inner end of the fan blade 9. After the guide wheel 172 rotates halfway, it reaches the spherical groove 16. At this time, the part with the rubber sleeve abuts against the inner wall of the spherical groove 16. Then, rotate the handle 177 clockwise by 90 degrees, so that the guide wheel 172 rotates 90 degrees in the spherical groove 16, that is, perpendicular to the track groove. Under the action of the spherical groove 16 and the track groove, plus the abutment of the side of the guide wheel 172 with the rubber sleeve, and the continuous reaction force provided by the compression spring 174, the fixation degree of the inner end of the fan blade 9 can be improved, ensuring the stability of the fan blade 9 when rotating at high speed. The magnetic block located on the inner wall of the arc groove 178 can prevent the handle 177 from moving without the action of external force, causing the guide wheel 172 to deflect.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
