Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fan lamps, and particularly relates to a fan lamp with quick installation of blades. BACKGROUND

[0002] Traditional fan lamps mostly adopt screw fixing or buckle connection in the blade fixing mode, and both modes have certain limitations. The screw fixing mode is stable in structure, but the installation and disassembly process is tedious, and tools are needed to be tightened or loosened one by one, which increases the maintenance time and operation difficulty, especially when working at a high place, which easily causes safety hazards. The buckle connection avoids the use of tools and improves the disassembly efficiency, but repeated operation easily leads to fatigue, fracture or loosening of the buckle structure, thereby reducing the reliability of the blade connection and affecting the overall safety. The conventional countermeasures include optimizing the screw material and design and enhancing the buckle strength, but these methods often bring problems such as cost increase and structural complication, and even new failure points may be caused due to excessive dependence on local structure, which cannot fundamentally solve the contradiction between convenience and reliability, so we hope to design a fan lamp with a new structure to solve this problem.

[0032] The two positioning grooves 10 and the two positioning protruding blocks 8 are matched in structure, size and distribution position, and the middle of the upper side of one end of the fan blade 9 provided with the two positioning grooves 10 is recessed downward to form a track groove; The inner end of the track groove penetrates the middle of one end of the fan blade 9 provided with the two positioning grooves 10, and the outer end of the track groove is connected with the inner concave spherical groove 16, the middle line of the track groove is collinear with the middle line of the spherical groove 16, and the left side and the right side of one end of the fan blade 9 inserted into the rotating disc 1 are respectively provided with one reverse buckle groove 11; The sliding part 122 located on the upper side of the fixed cover 5 is provided with a reverse buckle block, the structure and size of the reverse buckle block are matched with the structure and size of the reverse buckle groove 11, and the end of the fan blade 9 inserted into the rotating disc 1 is not in direct contact with the locking spring 13.

[0033] The lower side of the trapezoidal push block 7 is provided with a protruding plate, a threaded nut is penetrated and installed in the middle, the adjusting assembly 15 includes a shaft sleeve 151, the shaft sleeve 151 is fixed on the upper side of the inner wall of the rotating disc 1, the shaft sleeve 151 is rotationally connected with the outer side end of a lead screw 152, the inner side end of the lead screw 152 is threadedly movably connected with the protruding plate through the threaded nut, and a limiting rod 153 is transversely penetrated and installed at the inner side end of the lead screw 152 and used for limiting the threaded nut and the protruding plate.

[0034] Specifically, by arranging the mounting platform 2, the trapezoidal push block 7, the fixed plate cover, the sliding block 12 and the fan blade 9, in actual use, if the fan blade 9 needs to be installed, the user aligns the inner side end part of the fan blade 9 with the insertion slot on the rotating disc 1 and pushes it to be inserted, in this process, the inner side end part 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 arrangement of the upper side part of the fixed cover 5 to the bottom of the insertion slot), when the sliding blocks 12 on both sides of the fixed cover 5 are contacted, the reverse buckling blocks on the sliding parts 122 of the sliding blocks 12 slide and abut against the side edges of the inner side end of the fan blade 9, because the locking springs 13 are in a pre-stretched state, the reverse buckling blocks on the two sliding blocks 12 are in a state of being pulled tightly by the compressed springs 174, under the pushing and extruding of the inner side end of the fan blade 9, the compressed springs 174 are stretched again, and they generate a greater counteractive force trend to pull the two sliding blocks 12 in the opposite direction; When the two reverse buckling blocks reach the reverse buckling groove 11, the two reverse buckling blocks are quickly buckled into the reverse buckling groove 11 under the action of the locking springs 13, so that the two sliding blocks 12 lock and fix the inner side end part of the fan blade 9 through the reverse buckling groove 11 and the reverse buckling blocks, at the same time, the positioning groove 10 on the inner side end of the fan blade 9 is inserted with the positioning protrusions 8 in the insertion slot, so that the fan blade 9 will not shake after being locked and fixed, which helps to improve the stability of the fan blade 9 in use, when the fan blade 9 rotates at high speed, the centrifugal force acting on the fan blade 9 pulls the two sliding blocks 12 on both sides, because of the arrangement of the reverse buckling blocks and the reverse buckling groove 11, this makes the two sliding blocks 12 and the inner side end of the fan blade 9 be buckled and connected in a fixed structure, and the two sliding blocks 12 are limited by the stretched locking springs 13, which can ensure that the fan blade 9 will not be affected by the centrifugal force to be separated when rotating at high speed, and the safety of the high-speed rotation of the fan blade 9 is ensured, and the insertion type mounting method makes it unnecessary to use bolts or external installation tools when the fan blade 9 is installed, and only needs to be pushed and inserted to complete the stable and fixed installation, effectively solving the contradiction between convenience and reliability which cannot be fundamentally solved by optimizing the material and design of conventional screws and enhancing the buckle strength, improving the installation convenience and efficiency of the fan blade 9.

[0035] If it is necessary to disassemble and clean or replace the fan blade 9, the user first contacts the compression assembly 17 and rotates it counterclockwise by 90 degrees, and then uses 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 cooperates with a screwdriver or a socket wrench, and when installed, the lead screw 152 is in the initial position and does not affect the normal movement of the sliding block 12). When the lead screw 152 rotates, it pushes the cam plate to move, and at the same time, the trapezoidal push block 7 moves. Since the side of the connecting plate 123 close to the trapezoidal push block 7 is provided with a positioning plate 124, and the positioning plate 124 and the connecting plate 123 are provided with an inclined abutting portion, and the abutting portion and the side slope of the trapezoidal push block 7 slide and abut, and the angles of the two slopes are the same, with the movement of the trapezoidal push block 7, the abutting portion that slides and abuts with it is pushed by the side slope thereof, and the sliding blocks 12 on both sides are gradually pushed open in opposite directions, further making the inverted block in the inverted groove 11 gradually disengage, and after rotating a certain number of turns, the inverted block completely disengages from the inverted groove 11. At this time, only the fan blade 9 needs to be pulled out, which makes the disassembly and assembly of the fan blade 9 very convenient.

[0036] As a second embodiment of the present application: Please refer to Figures 1 to 8 The compression assembly 17 includes a mounting cylinder 175, the bottom of which is fixedly connected to the upper surface of the turntable 1, and the inner top of the mounting cylinder 175 is fixedly connected with an upper limiting plate 179. A compression spring 174 is installed in the mounting cylinder 175, the upper end of which is fixedly connected to the upper limiting plate 179, and a lower limiting plate 173 is movably installed at the bottom of the mounting cylinder 175. The lower limiting plate 173 movably abuts with the lower end of the compression spring 174, and the upper side of the lower limiting plate 173 is movably connected with the lower end of a rotating rod 176 through a spline, and the rotating rod 176 is supported to slide up and down. The upper side of the rotating rod 176 has a larger diameter than the lower side, and the lower part of the rotating rod 176 is located inside the compression spring 174.

[0037] The upper part of the rotating rod 176 penetrates through the upper limiting plate 179 and the top of the mounting cylinder 175 and is rotatably connected to the top of the mounting cylinder 175, and the upper end of the rotating rod 176 is provided with a handle 177 in an inverted L-shaped structure.

[0038] Based on the first embodiment, further, by arranging the pressing assembly 17, in actual use, when the fan blade 9 is installed, the guide wheel 172 is in the initial position, that is, the guide wheel 172 is parallel to the track groove, with the continuous entry of the inner end of the fan blade 9, the initial end of the track groove contacts the guide wheel 172, at this time, after the guide wheel 172 contacts the track groove, the guide wheel 172 is extruded by the inner end of the fan blade 9, and pushes the connecting rod 171 and the lower limit plate 173 to move upward to extrude the compression spring 174 in the inside of the mounting cylinder 175, because the middle of the upper side of the lower limit plate 173 is in spline connection with the lower end of the rotating rod 176 and supports the up-and-down sliding of the rotating rod 176, the upward movement of the lower limit plate 173 does not affect the rotating rod 176, and 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 the inner end part of the fan blade 9 is continuously extruded; The arrangement of the guide wheel 172 enables the inner end of the fan blade 9 to be not very difficult to insert and install, after the guide wheel 172 rotates by half, 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, at this time, the handle 177 is rotated clockwise by ninety degrees, so that the guide wheel 172 rotates by ninety 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, and in combination with the continuous reaction force provided by the compression spring 174, the side of the guide wheel 172 with the rubber sleeve abuts against, the fixing degree of the inner end of the fan blade 9 is improved, the stability of the fan blade 9 in high rotation is ensured, and the magnetic block in the inner wall of the arc-shaped groove 178 can avoid the movement of the handle 177 under the action of no external force to cause the deflection of the guide wheel 172.
