It can be understood that the connecting member 400 of the present invention can be the above-mentioned connecting ring for connecting the rotor 530 of the driving motor 500 and the fan blades 320, and the connecting member 400 of the present invention can be the above-mentioned junction box for connecting the lamp and the bottom cover 310.

[0046] In some specific embodiments of the present utility model, refer to Figure 1 and Figure 4, the first part includes a bottom cover 310, and the second part includes a stator 510 of a drive motor 500 connected to an inner member. Specifically, the fan includes a bottom cover 310 and a connecting member 400 for connecting an inner member (such as a lamp). The quick installation structure includes a first mounting member 100 and a second mounting member 200. The first mounting member 100 is connected to the bottom cover 310. The first mounting member 100 is provided with a mounting hole 110. One end of the second mounting member 200 is connected to the connecting member 400. Among them, the width of the mounting hole 110 decreases in the rotation direction of the fan to allow the end of the second mounting member 200 away from the bottom cover 310 to pass through the mounting hole 110, and then the bottom cover 310 is connected to the connecting member 400. Further, the mounting hole 110 is spaced from the bottom cover 310.

[0047] In some specific embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 4 , the first part includes a fan blade 320, and the second part includes a rotor 530 of a drive motor 500. Specifically, the fan includes a fan blade 320 and a connecting member 400 for connecting the drive motor 500. The quick installation structure includes a first mounting member 100 and a second mounting member 200. The first mounting member 100 is connected to the fan blade 320. The first mounting member 100 is provided with a mounting hole 110. One end of the second mounting member 200 is connected to the connecting member 400. Among them, the width of the mounting hole 110 decreases in the rotation direction of the fan to allow the end of the second mounting member 200 away from the fan blade 320 to pass through the mounting hole 110, and then the bottom cover 310 is connected to the connecting member 400.

[0048] In some specific embodiments of the present invention, the second width 112 is greater than the diameter of the second mounting member 200. The first width 111 is substantially the same as the width of the second mounting member 200. The first part includes a fan blade 320, and the second part includes a rotor 530 of a drive motor 500. The first part together with the first mounting member 100 rotates in a rotation direction when the fan is working. The mounting hole 110 of the first mounting member 100 has a first width 111 in the part along the rotation direction and a second width 112 in the part against the rotation direction.

[0049] Specifically, refer to Figure 2 , Figure 3 and Figure 9 , when the fan is working, it rotates in a rotation direction. For example, refer to Figure 2Counterclockwise rotation (viewed from below), the portion of the mounting hole 110 having the second width 112 and the portion having the first width 111 are arranged in the counterclockwise direction. The second width 112 is greater than the diameter of the second mounting member 200, and the first width 111 is substantially the same as the width of the second mounting member 200. When the second mounting member 200 passes through the mounting hole 110 from the side of the mounting hole 110 having the second width 112, rotate the fan blade in the direction opposite to the working rotation of the fan, so that the second mounting member 200 reaches the side of the mounting hole 110 having the first width 111. At this time, the outer wall of the second mounting member 200 can abut against the inner wall of the mounting hole 110. Since the second mounting member 200 is connected to the rotor 530 of the drive motor 500, at the moment of starting to rotate the fan, the rotor 530 drives the second mounting member 200 to rotate, and the second mounting member 200 moves relative to the first mounting member 100 in the direction of the mounting hole 110 having the first width 111, which can effectively prevent the fan blade 320 from falling off during the operation of the fan due to the second mounting member 200 reaching the side of the mounting hole 110 having the second width 112. In the quick installation structure of the fan parts of the embodiment of the present utility model, through the first mounting member 100 and the second mounting member 200, the quick connection of the first part and the connecting member 400 is realized, which is convenient for the maintenance of the second parts such as the bottom cover 310 and the fan blade 320. Specifically, the first mounting member 100 is arranged on the first part, the second mounting member 200 is connected to the connecting member 400, the second mounting member 200 passes through the mounting hole 110 from the side with a larger width of the mounting hole 110, and then rotate the bottom cover 310 in the direction opposite to the rotation of the fan, so that the second mounting member 200 can be fixed on the first mounting member 100. For example, as the second mounting member 200 slides in the mounting hole 110, due to the reduction of the width of the mounting hole 110, the second mounting member 200 can be clamped with the inner wall of the mounting hole 110, thereby realizing the connection of the first part and the connecting member 400, and fixing the first part on the fan body. It can be understood that the fan of the present invention can be provided with two sets of quick installation structures. One set of quick installation structures is applied to the connection between the fan blade 320 and the rotor 530 of the drive motor 500, and the other set of quick installation structures is applied to the connection between the bottom cover 310 (such as a lamp shade) and the inner member (such as a lamp) and the junction box.

[0050] In some specific embodiments of the present utility model, the first mounting member 100 includes a mounting plate 120 and two connecting plates 130. The opposite sides of the mounting plate 120 are respectively connected to the two connecting plates 130, and the mounting hole 110 is arranged on the mounting plate 120. For example, the first part includes a bottom cover 310, and the second part includes a stator 510 connected with an inner member. Refer to Figure 5 and Figure 6 , the first mounting member 100 is arranged on the upper side of the bottom cover 310 (refer to Figure 5) The two connecting plates 130 are parallel to each other, the mounting plate 120 is perpendicular to the connecting plates 130, one side of the connecting plate 130 is connected to the bottom cover 310, and the mounting plate 120 is connected to the side of the connecting plate 130 away from the bottom cover 310, so that the mounting plate 120 and the bottom cover 310 are spaced apart.

Specifically, the positioning plate 140 is disposed on the side of the mounting hole 110 and protrudes from the connecting plate 130 away from the bottom cover 310. When the end of the second mounting member 200 passes through the mounting hole 110, the positioning plate 140 can abut against the connecting member 400 to play a positioning role.

[0052] In some specific embodiments of the present utility model, the first part includes a fan blade 320, and the first mounting member 100 includes a mounting plate 120.

Further, a plurality of mounting holes 110 are provided on the mounting plate 120. For example, two mounting holes 110 are provided, and the plurality of mounting holes 110 are arranged along the circumference of the driving motor 500. Further, the first mounting member 100 further includes a reinforcing plate. The structure of the reinforcing plate is adapted to the structure of the mounting plate 120, and the reinforcing plate is also provided with a connection hole 410. The reinforcing plate is disposed between the mounting plate 120 and the connecting member 400, which is beneficial to improving the connection stability.

[0053] In some specific embodiments of the present utility model, the connecting member 400 is provided with a connecting convex ring 420 for connecting with the second mounting member 200 and a connection hole 410. The connecting convex ring 420 is disposed on the side of the connecting member 400 facing away from the first part, and the connecting convex ring 420 communicates with the connection hole 410. Refer to Figure 7 and Figure 8 , the second mounting member 200 is a structure similar to a long column. When the end of the second mounting member 200 on the side facing away from the first mounting member 100 enters the connection hole 410 and the connecting convex ring 420, the outer wall of the second mounting member 200 abuts against the inner walls of the connection hole 410 and the connecting convex ring 420, so that the second mounting member 200 can be fixed on the connecting member 400 to realize the connection between the second mounting member 200 and the connecting member 400.

[0054] In some specific embodiments of the present utility model, refer toFigure 7 and Figure 10 The connecting member 400 includes a connecting portion 430 and a connecting convex edge 440. The connecting convex edge 440 is connected to the outer periphery of the connecting portion 430. Specifically, the connecting portion 430 extends in the direction towards the fixing rod 600. The connecting portion 430 is provided with a connecting opening. The connecting convex edge 440 is connected to the outer wall of the connecting opening. A fixing through hole is provided on the side of the connecting portion 430 away from the connecting opening. The driving motor 500 is connected to the connecting member 400 through the fixing through hole. A connecting hole 410 is provided on the connecting convex edge 440. The second mounting member 200 passes through the connecting hole 410, so that the second mounting member 200 is connected to the connecting member 400.

[0055] For example, the first part includes a bottom cover 310, and the second part includes a stator connected with an inner member. Then the connecting member 400 can be a junction box. Refer to Figure 7 The connecting member 400 is provided with a connecting convex edge 440 and a box body as the connecting portion 430. The connecting convex edge 440 is connected to the outer periphery of the box body. The box body is provided with a connecting concave cavity for accommodating the parts. For example, the box body can be provided with a connecting concave cavity for accommodating wires. Specifically, the connecting concave cavity of the box body is recessed in the direction towards the driving motor 500. A connecting opening communicating with the connecting concave cavity is provided on one side of the box body. The connecting convex edge 440 is connected to the outer wall of the connecting opening. Thus, the connecting member 400 can be used as a junction box of a fan. The lamp (i.e., the inner member) is fixed on the box body and the wires are stored in the concave cavity of the box body. A fixing through hole is provided on the bottom wall of the box body (the side away from the connecting opening). The stator of the driving motor 500 passes through the fixing through hole and is connected with a fixing nut 520, so that the connecting member 400 is fixed on the stator of the driving motor 500. Further, the connecting member 400 is provided with a notch, and the wires enter the concave cavity of the box body through the notch.

[0056] Also for example, the first part includes a fan blade 320, and the second part includes a rotor 530 of the driving motor 500. Then the connecting member 400 can be a connecting ring. Refer to Figure 10 The outer periphery of the lower side of the connecting portion 430 is connected to the connecting convex edge 440. A fixing through hole is provided in the middle of the connecting portion 430. The stator of the driving motor 500 passes through the fixing through hole and is connected with an inner member (such as a lamp). The connecting portion 430 is recessed in the direction towards the driving motor 500 relative to the connecting convex edge 440. The upper side of the connecting portion 430 is connected to the lower side of the rotor 530 of the driving motor 500 through a motor screw. A connecting hole 410 is provided on the connecting convex edge 440 to realize the connection between the connecting ring and the second mounting member 200.

[0057] The quick installation structure of the fan parts of the present invention is provided with a first installation part 100 and a second installation part 200. The second installation part 200 can be connected to the junction box originally provided in the fan. The user replaces the original first part with a new first part provided with the first installation part 100, and the quick installation and disassembly can be realized. Compared with the original traditional method that requires replacing the whole fan or multiple parts, the use cost can be reduced.

[0058] Specifically, in some specific embodiments, the second installation part 200 can be a screw, the connecting column 210 is the screw rod of the screw, and the installation head 220 is the screw head of the screw. By drilling holes on the wiring plate as the connecting holes 410, the second installation part 200 can be connected to the connecting part 400. Further, the connecting holes 410 on the wiring plate are threaded holes, and a threaded connection method can be adopted between the second installation part 200 and the connecting part 400. Or, the two can be connected by sleeving an installation nut at the end of the screw rod, wherein the installation nut is arranged inside the junction box.

[0059] For example, referring to Figure 2 、 Figure 3 and Figure 4 For the installation of the fan blade 320, the second installation part 200 is a screw, and the connecting hole 410 is a screw hole. Through the threaded connection between the second installation part 200 and the connecting hole 410, the fan blade 320 can be fixed on the driving motor 500. Further, after the washer 230 is sleeved on the second installation part 200 and then passes through the installation hole 110, the washer 230 is arranged between the fan blade 320 and the screw head, so that the fan blade 320 can be locked on the connecting part 400, which is beneficial to ensuring the connection reliability.

[0060] Further, the second installation part 200 can be a double-diameter screw. The diameter of the screw rod at one end close to the screw head is larger than that at the other end. When the screw rod passes through the connecting hole 410 and is sleeved with a connecting nut, the second installation part 200 is fixed on the connecting part 400 by tightening the connecting nut. The present invention uses a screw as the second installation part 200, and the original junction box can be drilled and transformed by a household drilling gun, and then the second connecting part 400 can be connected to the connecting part 400 by a threaded connection method, so that the replacement or addition of the connecting part 400 is not required, and the quick installation and disassembly can be realized.

[0061] In some specific embodiments, the connecting member 400 is provided with a connecting hole 410, and the second mounting member 200 is provided with a thread to allow the second mounting member 200 to be threadedly connected to the connecting member 400. For example, the connecting member 400 is provided with a connecting hole 410, and the second mounting member 200 is provided with a thread to allow one end of the second mounting member 200 to pass through the connecting hole 410 to be connected to a connecting nut. Specifically, the diameter of the connecting nut is larger than the diameter of the connecting hole 410. After the end of the second mounting member 200 passes through the connecting hole 410, the connecting nut is sleeved on the end of the second mounting member 200 to achieve the connection between the second mounting member 200 and the connecting member 400. Another example is that the connecting member 400 is provided with a threaded hole, and the second mounting member 200 is a screw, and the screw is connected to the connecting member 400 through the threaded hole. Specifically, after a threaded hole is added to the connecting member 400 by a household drilling gun, the second mounting member 200 can be connected to the connecting member 400. Furthermore, by disassembling and connecting the second mounting member 200 and the first mounting member 100, the installation and disassembly of internal components such as lamps are realized.

[0062] In some specific embodiments, refer to Figure 4 and Figure 8 , the second mounting member 200 includes a connecting column 210 and a mounting head 220. One end of the connecting column 210 is connected to the mounting head 220, the end of the connecting column 210 far from the mounting head 220 is connected to the connecting member 400, and the width of the connecting column 210 is smaller than the width of the mounting head 220. Specifically, the width of the mounting hole 110 decreases in the direction of the fan rotation. Among them, the second width of the second side of the mounting hole 110 can be larger than the width of the mounting head 220, so that the mounting head 220 can pass through the mounting hole 110 and enter between the mounting plate 120 and the first part. And the side of the mounting hole 110 far from the second side is the first side, and the first width of its first side can be smaller than the width of the mounting head 220 and larger than the width of the connecting column 210. After the mounting head 220 passes through the mounting hole 110 through the second side of the mounting hole 110, the first mounting member 100 is rotated in the direction of the fan rotation, and the connecting column 210 reaches the first side of the mounting hole 110. At this time, the connecting column 210 is in the mounting hole 110, and the mounting head 220 is between the mounting plate 120 and the first part, and the mounting head 220 cannot pass through the mounting hole 110, thus realizing the connection and installation of the second mounting member 200 and the first mounting member 100. Correspondingly, when the first part is rotated in the direction opposite to the fan rotation, the connecting column 210 reaches the second side from the first side of the mounting hole 110. At this time, the mounting head 220 can pass through the mounting hole 110, realizing the disassembly of the first mounting member 100 and the second mounting member 200.

[0063] It can be understood that for the installation of the bottom cover 310, the installation holes 110 are spaced from the bottom cover 310. When the installation head 220 passes through the installation holes 110, it can contact the bottom cover 310, thereby achieving positioning. After the installation head 220 completely passes through the installation holes 110, that is, when the installation head 220 is between the installation plate 120 and the bottom cover 310, the bottom cover 310 is then rotated.

[0064] In some specific embodiments, referring to Figure 6 and Figure 9 , the width of the installation holes 110 decreases in the forward rotation direction of the fan. For example, the width of the installation holes 110 can gradually decrease from the second side to the first side. For another example, the installation holes 110 can be provided with circular holes 114 and long slots 113. The circular holes 114 communicate with the long slots 113, and the diameter of the circular holes 114 is greater than the width of the long slots 113. The circular holes 114 are provided on the second side, and the width of the circular holes 114 is greater than the end width of the second connecting member 400, so that the end of the second connecting member 400 can pass through the installation holes 110. Further, the width of the long slots 113 is less than the diameter of the installation head 220 and greater than the diameter of the connecting column 210. Further, the width of the long slots 113 gradually decreases in the direction of the first side.

[0065] In some specific embodiments, a clamping portion 115 for fixing the second mounting member 200 is provided on the inner wall of the installation holes 110. Referring to Figure 6 , the side surface of the first side end of the long slot 112 can be set as an arc surface matching the outer circumference of the connecting column 210. Clamping portions 115 are provided on both sides of the middle of the long slot 113. The width of the long slot 113 is slightly greater than the width of the connecting column 210, while the width at the clamping portion 115 is slightly less than the width of the connecting column 210. When the connecting column 210 slides from the second side to the first side, after passing through the clamping portion 115, one side of the connecting column 210 abuts against the side surface of the long slot 113 away from the first side, and the side of the connecting column 210 facing away from the first side abuts against the clamping portion 115, so that the connecting column 210 can be positioned in the installation holes 110, which is beneficial to improving the connection reliability. It can be understood that the installation plate 120 of the present invention can be made of an elastic material.

[0066] In some specific embodiments, when the second mounting member 200 enters the installation holes 110 and reaches the first side, one side surface of the first mounting member 100 contacts the anti - detachment member 150 to prevent the first part from detaching from the second part when the fan rotates in the reverse direction. For example, to prevent the fan blade 320 from detaching from the drive motor 500 when the fan rotates in the reverse direction. Referring to Figure 3 and Figure 9, the anti-disengagement member 150 is fixed to the connecting member 400. For example, the anti-disengagement member 150 can be a screw, and the connecting member 400 is provided with a threaded hole. The anti-disengagement member 150 is fixed to the connecting member 400 by threaded connection, and the screw head of the anti-disengagement member 150 protrudes from the side of the connecting member 400 facing away from the driving motor 500. When the fan blade 320 is installed on the driving motor 500, the anti-disengagement member 150 is provided on the side of the first mounting member 100 facing the forward rotation direction of the fan. The screw head of the anti-disengagement member 150 contacts the first mounting member 100. When the fan rotates in the reverse direction, the anti-disengagement member 150 plays a limiting role on the first mounting member 100, which can effectively prevent the first mounting member 100 from moving relative to the second mounting member 200, thereby effectively preventing the connecting column 210 from sliding from the first side to the second side and entering the circular hole 114.

[0067] In some specific embodiments, the connecting column 210 includes a first column body 211 and a second column body 212 for positioning. The second column body 212 is disposed between the first column body 211 and the mounting head 220, and the diameter of the second column body 212 is greater than the diameter of the first column body 211. Refer to Figure 8 , the connecting member 400 is provided with a connecting hole 410. The diameter of the connecting hole 410 is greater than the diameter of the first column body 211 and less than the diameter of the second column body 212. When the first column body 211 passes through the connecting hole 410, the second column body 212 can abut against the connecting member 400, thereby achieving positioning. Further, after the first column body 211 passes through the connecting hole 410, a mounting nut can be sleeved on the end of the first column body 211. By tightening the mounting nut, the second mounting member 200 is fixed to the connecting member 400.
