Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically to an oscillating structure. Background Technology

[0002] The applicant previously filed a novel oscillating cylindrical booster fan (patent application number: 202422824338, not yet granted before the filing date of this application). Its rotating mechanism includes a rotary motor fixed inside a fixed housing, a crankshaft fixed to the motor shaft of the rotary motor, a connecting rod connected to the end of the crankshaft, and a rocker arm connected to the end of the connecting rod and to the rotating housing. When the rotary motor rotates, the crankshaft drives the connecting rod to rotate, which in turn drives the rocker arm to rotate. The rocker arm then drives the rotating housing to rotate on the fixed housing, thereby rotating the booster fan body. The oscillating effect, with the fan base fixed to the fixed shell and the fan body fixed to the rotating shell, presents the following problems in actual use: when the machine is dropped or the head is twisted without power, because the fixed shell is directly fixed to the base (actually fixed to the base's fixing tube), the fixed shell and the base cannot rotate relative to each other. Therefore, when the rotating shell rotates with the fixed shell, its rotating mechanism is subject to external leverage force, which can cause damage. That is, when the rotating shell is propelled by external force to generate rotational force with the fixed shell, due to the non-rotatable nature of the fixed shell, the internal rotating mechanism is easily damaged by additional external leverage force. Therefore, it needs to be improved. Utility Model Content

[0003] The main purpose of this utility model is to solve the above-mentioned technical problems and provide an oscillating structure and an oscillating booster fan.

[0004] The technical solution adopted by this utility model is as follows: a swaying structure, including a support tube, a bottom shell rotatably inserted into the support tube via a rotating assembly, a top shell rotatably mounted on the bottom shell, and a rotating mechanism installed inside the bottom shell for driving the top shell to rotate. The rotating assembly includes a fixing ring fixed to the bottom of the bottom shell, an upper insert tube fixed to the top surface of the fixing ring and inserted into the bottom shell, a lower insert tube fixed to the bottom surface of the fixing ring and inserted into the support tube, a first rotating component rotatably sleeved on the top of the lower insert tube, and a second rotating component rotatably sleeved on the bottom of the lower insert tube. The first rotating component is fixed to the support tube by bolts.

[0005] The first rotating component is provided with a bolt positioning ring.

[0006] The lower insertion tube has multiple positioning screws in the middle for positioning the first rotating component, and multiple positioning screws and anti-disengagement rings at the bottom for positioning the second rotating component.

[0007] A first thrust ball bearing is provided between the top shell and the bottom shell. The rotating mechanism includes a rotary motor fixed inside the bottom shell, a crankshaft fixed to the motor shaft of the rotary motor, a connecting rod connected to the end of the crankshaft, and a rocker arm connected to the end of the connecting rod and connected to the top shell.

[0008] The beneficial effects of this utility model are as follows: The bottom shell of this utility model is installed on the support tube through a rotating kit, which enables the bottom shell and the support tube to rotate relative to each other. This solves the problem that the fixed shell cannot rotate relative to the base in the current technology, and solves the problem that twisting the fan angle will damage the rotating mechanism when the power is off or when the machine is dropped.

[0012] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] Please refer to Figure 1 , Figure 2As shown, this utility model provides a swaying structure, including a support tube 10, a bottom shell 30 optionally rotatably inserted into the support tube 10 via a rotating assembly 20, a top shell 40 rotatably mounted on the bottom shell 30, and a rotating mechanism 50 installed inside the bottom shell 30 for driving the top shell 40 to rotate. The rotating assembly 20 includes a fixing ring 21 fixed to the bottom of the bottom shell 30, an upper insertion tube 22 fixed to the top surface of the fixing ring 21 and inserted into the bottom shell 30, a lower insertion tube 23 fixed to the bottom surface of the fixing ring 21 and inserted into the support tube 10, a first rotating member 24 rotatably sleeved on the top of the lower insertion tube 23, and a rotatable sleeve... A second rotating member 25 is attached to the bottom of the lower insertion tube 23. The first rotating member 24 is fixed to the support tube 10 by bolts. In actual use, the second rotating member 25 is inserted into the interior of the support tube 10 and is press-fitted with the inner wall of the support tube 10, while the first rotating member 24 is fixed to the support tube 10. Due to the rotatable nature of the first rotating member 24 and the second rotating member 25, the lower insertion tube 23 can rotate within the support tube 10, solving the problem that the bottom shell 30 (equivalent to the fixed shell in the background technology) cannot rotate relative to the base in the current technology, and that twisting the fan angle will damage the rotating mechanism when there is no power or when the machine is dropped.

[0015] To better secure the first rotating component 24, the first rotating component 24 is provided with a bolt positioning ring 241 to achieve precise positioning of the rotating component 24.

[0016] In this embodiment, the lower insertion tube 23 is provided with a plurality of positioning screws C for positioning the first rotating member 24 in the middle part, and the lower insertion tube 23 is provided with a plurality of positioning screws C and anti-detachment ring D for positioning the second rotating member 25 at the bottom, so as to enable the first rotating member 24 and the second rotating member 25 to rotate on the outer surface of the lower insertion tube 23 without falling off.

[0017] It is worth mentioning here that there is a certain friction between the first rotating member 24 and the second rotating member 25 and the lower insertion tube, which ensures that the two can rotate but do not rotate arbitrarily, which is equivalent to the effect of a damping shaft.

[0018] In this embodiment, a first thrust ball bearing 60 is provided between the top shell 40 and the bottom shell 30 to enable the top shell 40 to rotate on the bottom shell 30. The rotating mechanism 50 includes a rotary motor 51 fixed inside the bottom shell 30, a crankshaft 52 fixed to the motor shaft of the rotary motor 51, a connecting rod 53 connected to the end of the crankshaft 52, and a rocker arm 54 connected to the end of the connecting rod 53 and connected to the top shell 40. When the rotary motor 51 rotates, the crankshaft 52 drives the connecting rod 53 to rotate, the connecting rod 53 drives the rocker arm 54 to rotate, and then the rocker arm 54 drives the top shell 40 to rotate on the bottom shell 30. In actual use, the support tube is fixed to the fan base, and the fan body is fixed to the top shell 40, thereby achieving the effect of driving the fan body to oscillate.

[0019] The present invention aims to achieve the following: the bottom shell of the present invention is mounted on the support tube by a rotating assembly, which enables relative rotation between the bottom shell and the support tube. This solves the problem that the fixed shell cannot rotate relative to the base in the current technology, and also solves the problem that twisting the fan angle will damage the rotating mechanism when the power is off or when the machine is dropped.

[0020] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
