Description

Technical Field

[0001] The invention relates to a ceiling fan capable of being adjusted at multiple angles. Background Art

[0002] Ceiling fans used in workshops, warehouses, garages and other places are usually able to adjust the up and down (i.e. pitch) angle and left and right angle so that the wind can blow to a specified position. For example, an adjustable ceiling fan disclosed in Chinese utility model patent specification CN203035576U achieves angle adjustment of the ceiling fan by enabling relative movement of a first suspension rod and a second suspension rod. However, each angle adjustment requires first loosening the adjusting bolt so that the second suspension rod can move relative to the first suspension rod, and then tightening the adjusting bolt after the adjustment is completed to lock the second suspension rod. This adjustment method is inconvenient to use, especially since the adjusting bolt is in a high-altitude position and is not easy to screw. Summary of the invention

[0003] The object of the present invention is to provide a ceiling fan that can be adjusted at multiple angles, comprising a hanger and a fan body, the hanger comprising a suspension rod and a movable frame; the middle part of the movable frame is pivotally connected to the lower end of the suspension rod so that the movable frame can rotate relative to the suspension rod around the axis of the suspension rod; the movable frame has two opposing arms, the fan body is clamped between the two arms, and the fan body is pivotally connected to the two arms respectively so that the fan body can rotate relative to the movable frame around a horizontal axis, and the horizontal axis is perpendicular to the axis of the suspension rod; the lower part of the fan body is provided with a handle for a user to hold to drive the fan body; a first lock mechanism is provided between the lower end of the suspension rod and the movable frame, which switches between a locked state and an unlocked state to limit or allow the movable frame to rotate relative to the suspension rod; a second lock mechanism is provided between the fan body and at least one arm, which switches between a locked state and an unlocked state to limit or allow the fan body to rotate relative to the movable frame; an operating mechanism for a user to operate is provided on the handle; the operating mechanism is simultaneously linked with the first lock mechanism and the second lock mechanism to drive the first lock mechanism and the second lock mechanism to switch between a locked state and an unlocked state.

[0004] The present invention arranges an operating mechanism on the handle so that the user can operate the first locking mechanism and the second locking mechanism on the handle when adjusting the angle of the fan body, thereby improving the convenience of adjusting the angle of the fan body so that the user can manually change the blowing direction of the fan body at any time.

DETAILED DESCRIPTION

[0056] The present application scheme is further described below in conjunction with the accompanying drawings.

[0057] like Figures 1 to 33 A ceiling fan with multi-angle adjustment shown in the figure comprises a hanger and a fan body 10, wherein the hanger comprises a hanger rod 20 and a movable frame 30. In this embodiment, the movable frame 30 is in a semicircular arc shape;

[0058] The middle portion of the movable frame 30 is pivotally connected to the lower end of the suspension rod 20 so that the movable frame 30 rotates relative to the suspension rod 20 around the axis L1 of the suspension rod, thereby achieving left and right swing adjustment of the fan body 10;

[0059] The movable frame 30 has two opposing arms, the fan body 10 is clamped between the two arms, and the fan body 10 is pivotally connected to the two arms respectively so that the fan body 10 rotates relative to the movable frame 30 around a horizontal axis L2, thereby realizing the up and down swing adjustment of the fan body 10, and the horizontal axis L2 is perpendicular to the axis L1 of the suspension rod;

[0060] The fan body 10 is provided with a handle 40 at the bottom thereof for the user to hold to drive the fan body 10. The user can hold the handle to drive the fan body 10 to swing left and right and up and down;

[0061] A first locking mechanism is provided between the lower end of the suspension rod 20 and the movable frame 30, which switches between a locked state and an unlocked state to limit or allow the movable frame 30 to rotate relative to the suspension rod 20;

[0062] A second locking mechanism is provided between the fan body 10 and at least one arm, which switches between a locked state and an unlocked state to limit or allow the fan body 10 to rotate relative to the movable frame 30;

[0063] The handle 40 is provided with a manipulation mechanism 50 for the user to operate;

[0064] The operating mechanism 50 is linked with the first locking mechanism and the second locking mechanism at the same time to drive the first locking mechanism and the second locking mechanism to switch between a locked state and an unlocked state.

[0065] This technical solution uses a first locking mechanism and a second locking mechanism to lock or unlock the left and right and up and down swinging of the fan body, so that when the angle of the fan body needs to be adjusted, the fan body can be unlocked to allow it to swing to a suitable angle, and after the angle adjustment is completed, the fan body can be locked so that it can stay stably and reliably at the adjusted angle.

[0066] The operating mechanism 50 has a plurality of gears for the user to choose from, including the first gear, the second gear, the third gear and the fourth gear, wherein:

[0067] When the operating mechanism 50 is in the first gear position, the first locking mechanism and the second locking mechanism are both in a locked state. At this time, the movable frame 30 and the fan body 10 are both locked, and the movable frame 30 and the fan body 10 cannot rotate, thereby allowing the fan body 10 to stably stay in the position after the adjustment is completed;

[0068] When the operating mechanism 50 is in the second gear position, the first locking mechanism is in a locked state, and the second locking mechanism is in an unlocked state. At this time, the movable frame 30 is locked and cannot rotate, and the fan body 10 is unlocked and allowed to rotate, so that the fan body 10 can be swung up and down while being fixed in the left and right directions.

[0069] When the operating mechanism 50 is in the third gear, the first locking mechanism is in an unlocked state, and the second locking mechanism is in a locked state. At this time, the movable frame 30 is unlocked and allowed to rotate, and the fan body 10 is locked and cannot rotate, so that the fan body 10 can be swung in the left and right directions while being fixed in the up and down directions.

[0070] When the operating mechanism 50 is in the 4th gear, the first locking mechanism and the second locking mechanism are both in the unlocked state. At this time, the movable frame 30 and the fan body 10 are both unlocked, and the movable frame 30 and the fan body 10 are allowed to rotate, so that the fan body 10 can be adjusted and swung in the up and down directions and the left and right directions at the same time.

[0071] This technical solution improves the flexibility of adjusting the angle of the fan body by setting multiple gears for users to choose from.

[0072] The operating mechanism 50 includes a button 501 for the user to press;

[0073] The button 501 can be installed on the handle 40 to be lifted up and down, and when the button 501 is pressed, it will drop step by step from the highest position, the second highest position, the second lowest position to the lowest position, wherein:

[0074] When the button 501 is in the highest position, the operating mechanism is in the first gear position, wherein Fig. 27 The button 501 is shown in the uppermost position;

[0075] When the button 501 is in the second highest position, the operating mechanism is in the second gear position, wherein Fig.28 The button 501 is shown in the second highest position;

[0076] When the button 501 is in the second lowest position, the operating mechanism is in the third gear, wherein Fig.29 The button 501 is shown in the second lowest position;

[0077] When the button 501 is in the lowest position, the operating mechanism is in the 4th gear, wherein: Fig.30 The button 501 is shown in the lowest position;

[0078] A first elastic reset mechanism is provided between the handle 40 and the button 501 so that the button 501 always has a tendency to return to the highest position. In this embodiment, the first elastic reset mechanism includes a first compression spring 502 provided between the handle 40 and the button 501, one end of the first compression spring 502 is connected to the button 501, and the other end of the first compression spring 502 is connected to the handle 40.

[0079] This technical solution adopts a button so that the user can operate the operating mechanism while holding the handle.

[0081] The first locking mechanism lower portion includes a first locking pin 601 that slides up and down between an extended position and a retracted position to be inserted into or removed from the first locking mechanism upper portion;

[0082] The first locking pin 601 is inserted into the upper part of the first locking mechanism when it is in the extended position, so that the first locking mechanism is in a locked state;

[0083] The first lock pin 601 is pulled away from the upper portion of the first lock mechanism when it is in the retracted position, so that the first lock mechanism is in an unlocked state;

[0084] The lower part of the first locking mechanism also includes a second elastic return mechanism that allows the first locking pin 601 to always have a tendency to return to the extended position;

[0085] The operating mechanism 50 further includes a first column 503, a first wire wheel 504 and a first traction wire 505;

[0086] The first column 503 is rotatably mounted on the handle 40, and the upper end of the first column 503 passes through the button 501, and the lower end of the first column 503 extends into the handle 40. The first wire wheel 504 is fixedly mounted on the lower end of the first column 503 so that the first wire wheel 504 rotates with the first column 503;

[0087] The first column 503 is a cylindrical cam with a first curved groove on the cylindrical surface;

[0088] The button 501 is provided with a first push rod 506 extending into the first curved groove, and the first column 503 and the first push rod 506 form a cylindrical cam mechanism;

[0089] The first curved groove includes, from the upper end to the lower end of the first column 503, a first highest position stay section 507, a first upper connecting section 508, a first high position stay section 509, a first middle connecting section 510, a first low position stay section 511, a first lower connecting section 512 and a first lowest position stay section 513, wherein:

[0090] When the button 501 is at the highest position, the first push rod 506 is at the first highest position stay section 507;

[0091] When the button 501 is in the second highest position, the first push rod 506 is in the first high position stay section 509;

[0092] When the button 501 is in the second lowest position, the first push rod 506 is in the first low position stay section 511;

[0093] When the button 501 is at the lowest position, the first push rod 506 is at the first lowest position stay section 513;

[0094] The first upper connecting section 508 is connected between the first highest position stop section 507 and the first high position stop section 509, and the first highest position stop section 507, the first upper connecting section 508 and the first high position stop section 509 are all in a straight line parallel to the axis of the first column 503, so that the first column 503 and the first wire wheel 504 are always stationary during the process that the first push rod 506 follows the button 501 to descend from the highest position to the second highest position and rise from the second highest position to the highest position;

[0095] The first middle connecting section 510 is connected between the first high-position staying section 509 and the first low-position staying section 511, and the first middle connecting section 510 is in a spiral shape winding around the first column 503, so that the first column 503 and the first wire wheel 504 rotate forwardly when the first push rod 506 follows the button 501 to descend from the second highest position to the second lowest position, and the first column 503 and the first wire wheel 504 rotate reversely when the first push rod 506 follows the button 501 to rise from the second lowest position to the second highest position. A middle connecting section 510 is wound around the first column 503 for one circle, so that the first column 503 and the first wire wheel 504 rotate forward or reversely for one circle (i.e. 360 degrees) when the first push rod 506 follows the button 501 to descend from the second highest position to the second lowest position or to rise from the second lowest position to the second highest position. In this embodiment, the cylindrical cam mechanism composed of the first column 503 and the first push rod 506 is used to convert the up and down lifting linear motion of the button 501 into the forward rotation and reverse rotation of the first column 503 and the first wire wheel 504;

[0096] The first lower connecting section 512 is connected between the first low-position staying section 511 and the first lowest-position staying section 513, and the first low-position staying section 511, the first lower connecting section 512 and the first lowest-position staying section 513 are all in a straight line parallel to the axis of the first column 503, so that the first column 503 and the first wire wheel 504 are always stationary during the process that the first push rod 506 follows the button to descend from the second lowest position to the lowest position and rise from the lowest position to the second lowest position;

[0097] The lower end of the first traction line 505 is connected to the first wire wheel 504;

[0098] The upper end of the first traction line 505 passes through the handle 40, the fan body 10 and the movable frame 30 and is connected to the first locking pin 601. In this embodiment, the first traction line 505 is covered with a first wire tube 514 for positioning the first traction line 505, and the first wire tube 514 is fixed in the fan body 10;

[0099] The first traction line 505 is wound around the first wire wheel 504 when the first wire wheel 504 rotates forwardly to pull the first locking pin 601 to overcome the force of the second elastic reset mechanism and slide down from the extended position to the retracted position;

[0100] The first pulling line 505 is released from the first wire wheel 504 when the first wire wheel 504 rotates in the reverse direction, so that the first locking pin 601 slides from the retracted position to the extended position under the action of the second elastic reset mechanism.

[0101] This technical solution can remotely control the first locking mechanism with the help of the first traction line, can retract and release the first traction line with the help of the rotation of the first wire wheel, and can make the button and the first wire wheel linked with the help of the cylindrical cam mechanism to satisfy the switching of the operating mechanism and control the gear position. At the same time, compared with other linkage mechanisms, the cooperation of the cylindrical cam mechanism and the first traction line can simplify the structure and save occupied space.

[0102] The second locking mechanism includes a second locking mechanism left portion installed on a support arm of the movable frame and a second locking mechanism right portion installed on the fan body 10;

[0103] The right portion of the second locking mechanism includes a second locking pin 701 that slides left and right between an extended position and a retracted position to be inserted into or removed from the left portion of the second locking mechanism;

[0104] The second locking pin 701 is inserted into the left part of the second locking mechanism when it is in the extended position, so that the second locking mechanism is in a locked state;

[0105] When the second lock pin 701 is in the retracted position, it is pulled away from the left portion of the second lock mechanism, so that the second lock mechanism is in an unlocked state;

[0106] The right part of the second locking mechanism also includes a third elastic reset mechanism that allows the second locking pin 701 to always have a tendency to return to the extended position;

[0107] The control mechanism 50 further includes a second column 515, a second wire wheel 516 and a second traction wire 517;

[0108] The second column 515 is rotatably mounted on the handle 40, and the second column 515 is parallel to the first column 503. The upper end of the second column 515 passes through the button 501, and the lower end of the second column 515 extends into the handle 40. The second wire wheel 516 is fixedly mounted on the lower end of the second column 515 so that the second wire wheel 516 rotates with the second column 515.

[0109] The second column 515 is a cylindrical cam with a second curved groove on the cylindrical surface;

[0110] The button 501 is provided with a second push rod 518 extending into the second curved groove, and the second column 515 and the second push rod 518 form a cylindrical cam mechanism;

[0111] The second curved groove includes, from the upper end to the lower end of the second column 516, a second highest position stay section 519, a second upper connecting section 520, a second high position stay section 521, a second middle connecting section 522, a second low position stay section 523, a second lower connecting section 524 and a second lowest position stay section 525, wherein:

[0112] When the button 501 is at the highest position, the second push rod 518 is at the second highest position stay section 519;

[0113] When the button 501 is at the second highest position, the second push rod 518 is at the second high position stay section 521;

[0114] When the button 501 is in the second low position, the second push rod 518 is in the second low position stay section 523;

[0115] When the button 501 is at the lowest position, the second push rod 518 is at the second lowest position stay section 525;

[0117] The second upper connecting section 520 is connected between the second highest position stop section 519 and the second high position stop section 521, and the second upper connecting section 520 is in a spiral shape winding around the second column 515, so that the second column 515 and the second wire wheel 516 rotate forwardly when the second push rod 518 follows the button 501 to descend from the highest position to the second highest position, and the second column 515 and the second wire wheel 516 rotate reversely when the second push rod 518 follows the button 501 to rise from the second highest position to the highest position;

[0118] The spiral direction of the second upper connecting section 520 is the same as the spiral direction of the first middle connecting section 510;

[0119] The second middle connecting section 522 is connected between the second high-position stop section 521 and the second low-position stop section 523, and the second middle connecting section 522 is in a spiral shape winding around the second column 515, so that the second column 515 and the second wire wheel 516 rotate in the opposite direction when the second push rod 518 follows the button 501 to descend from the second high position to the second low position, and the second column 515 and the second wire wheel 516 rotate in the positive direction when the second push rod 518 follows the button 501 to rise from the second low position to the second high position;

[0120] The spiral direction of the second middle connecting section 522 is opposite to the spiral direction of the second upper connecting section 520;

[0121] The second lower connecting section 524 is connected between the second low-position staying section 523 and the second lowest position staying section 525, and the second lower connecting section 524 is in a spiral shape winding around the second column 515, so that the second column 515 and the second wire wheel 516 rotate forwardly when the second push rod 518 follows the button 501 to descend from the second lowest position to the lowest position, and the second column 515 and the second wire wheel 516 rotate reversely when the second push rod 518 follows the button 501 to rise from the lowest position to the second lowest position;

[0122] The spiral direction of the second lower connecting section 524 is the same as the spiral direction of the second upper connecting section 520;

[0123] In this embodiment, the second upper connecting section 520, the second middle connecting section 522 and the second lower connecting section 524 are all coiled around the second column 515. In this embodiment, the cylindrical cam mechanism composed of the second column 515 and the second push rod 518 is used to convert the up and down lifting linear motion of the button 501 into the forward rotation and reverse rotation of the second column 515 and the second wire wheel 516.

[0124] The lower end of the second traction line 517 is connected to the second wire wheel 516;

[0125] The upper end of the second traction line 517 passes through the handle 40 and the fan body 10 and is connected to the second locking pin 701. In this embodiment, the second traction line 517 is covered with a second wire tube 526 for positioning the second traction line 517, and the second wire tube 526 is fixed in the fan body 10;

[0126] The second traction wire 517 is wound around the second wire wheel 516 when the second wire wheel 516 rotates forward to drive the second locking pin 701 to slide rightward from the extended position to the retracted position;

[0127] The second pulling wire 517 is released from the second wire wheel 516 when the second wire wheel 516 rotates in the reverse direction, so that the second locking pin 701 slides leftward from the retracted position to the extended position under the action of the third elastic reset mechanism.

[0128] This technical solution can remotely control the second locking mechanism with the help of the second traction line, can retract and release the second traction line with the help of the rotation of the second wire wheel, and can make the button and the second wire wheel linked with the help of the cylindrical cam mechanism to satisfy the switching of the operating mechanism and control the gear position. At the same time, compared with other linkage mechanisms, the use of the cylindrical cam mechanism and the first traction line can simplify the structure and save occupied space.
