Description

Technical Field

[0001] This utility model relates to the field of kite wheel technology, and in particular to a kite wheel. Background Technology

[0002] Kite reels are auxiliary tools used when flying kites. Their structures vary, but they mainly consist of a reel and a handle. A bearing connects the two, allowing the reel to rotate freely in both directions, enabling the reel to be wound and released. Currently, kite reels are mainly divided into hand-held and backpack-held reels. Hand-held kite reels have a relatively simple structure, are small in size, and are easy to use, but usually do not have a speed-changing function. Back-held kite reels have a complex structure, multiple functions, and are relatively large, allowing the flight of larger kites; they usually have speed-changing functions.

[0003] For example, in the prior art, a kite reel with a braking structure, disclosed in CN219681672U, includes a winding reel and a handle. The winding reel and the handle are rotatably connected, and an ABS rotating shaft is provided between the winding reel and the handle. An ABS braking shaft and a brake handle are provided on the handle, enabling braking of the kite reel. This type of kite reel is for hand-cranked use. When reeling in or letting out the line, rotating the handle once results in only one rotation of the kite line around the reel. This does not meet the requirement that the reeling speed and the hand-cranking speed are not consistent. For example, to achieve fast reeling in, one rotation by hand would allow the kite line to rotate more than one turn around the reel. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of this utility model is to provide a kite reel that can meet the usage requirements of inconsistent line winding speed and hand-cranked speed.

[0005] To achieve the above objectives, this utility model provides a kite reel, including a winding reel and a handle. The winding reel has a mounting hole, an internal gear ring is provided on the inner circumferential surface of the winding reel, a sun gear is provided on the outer circumferential surface of the handle, the sun gear is located inside the internal gear ring, a planetary gear is provided between the internal gear ring and the sun gear, the planetary gear meshes with the internal gear ring and the sun gear, and the planetary gear is connected to a rotating structure.

[0006] As a further improvement, the inner circumferential surface of the winding wheel is rotatably connected to the internal gear ring, and a locking mechanism is provided between the winding wheel and the internal gear ring. The locking mechanism is used to adjust the connection state between the winding wheel and the internal gear ring.

[0007] As a further improvement, a bearing is installed between the inner circumferential surface of the winding wheel and the internal gear ring, the outer ring of the bearing is fixedly connected to the inner circumferential surface of the winding wheel, and the inner ring of the bearing is fixedly connected to the internal gear ring;

[0008] The planetary gear is connected to the planetary carrier, the rotating structure is mounted on the planetary carrier, a locking block is slidably provided on the planetary carrier, and a locking slot is provided on the outer ring of the bearing. The locking block and the locking slot engage to form the locking mechanism.

[0009] As a further improvement, the planetary gears are provided in multiples and are evenly distributed around the sun gear. The planet carrier is annular, and two fixing blocks are fixed on the outer circumferential surface of the planet carrier. The two fixing blocks are arranged opposite to each other, and a sliding groove is formed between the two fixing blocks. The locking block is slidably disposed in the sliding groove. The length direction of the fixing blocks and the length direction of the sliding groove both extend radially along the planet carrier.

[0010] Due to the aforementioned distinguishing technical features, this utility model has the following beneficial technical effects:

[0011] The kite reel provided by this utility model is equipped with an internal gear ring, planetary gears and a sun gear. When the handle is held and the planetary gears are driven to rotate, the planetary gears will drive the internal gear ring to rotate. By setting a suitable gear ratio for the internal gear ring, planetary gears and sun gear, a certain transmission ratio can be achieved, so that when the planetary gears rotate around the sun gear once, the internal gear ring and the winding reel can rotate more than once, which facilitates quick line reeling.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] See Figures 1-5 A kite reel includes a winding reel 1 and a handle 2. The outer circumference of the winding reel has a winding groove for winding kite line. The winding reel 1 has a mounting hole. The inner circumference of the winding reel has an internal gear ring 4. The outer circumference of the handle has a sun gear 21 located inside the internal gear ring. A planetary gear 5 is provided between the internal gear ring and the sun gear. The planetary gear meshes with the internal gear ring and the sun gear. The planetary gear connects to a rotating structure. Specifically, the rotating structure can be a handle or a power mechanism such as a motor. When in use, the handle is held, and the rotating structure drives the planetary gear to rotate around the sun gear. When the planetary gear rotates, it simultaneously drives the internal gear ring to rotate. By setting an appropriate gear ratio for the internal gear ring, planetary gear, and sun gear, a certain transmission ratio can be achieved, so that when the planetary gear rotates once around the sun gear, the internal gear ring and the winding reel can rotate more than once, which facilitates quick line reeling.

[0020] In this embodiment, the inner circumferential surface of the winding wheel is rotatably connected to the internal gear ring, and a locking mechanism is provided between the winding wheel and the internal gear ring. The locking mechanism is used to adjust the connection state between the winding wheel and the internal gear ring.

[0021] In this embodiment, a bearing 3 is installed between the inner circumferential surface of the winding wheel and the internal gear ring. The outer ring 12 of the bearing is fixedly connected to the inner circumferential surface of the winding wheel, and the inner ring 41 of the bearing is fixedly connected to the internal gear ring. There are various connection methods, such as bolting, snap-fitting, etc.

[0022] The planetary gear is connected to the planetary carrier 22. The rotating structure is mounted on the planetary carrier. A locking block is slidably provided on the planetary carrier. A locking slot 13 is provided on the outer ring of the bearing. The locking block and the locking slot engage to form a locking mechanism. The locking mechanism can also adopt other existing structures that can adjust the connection state between the winding wheel and the internal gear ring, such as pins, buckles, etc.

[0023] In this embodiment, there are multiple planetary gears, which are evenly distributed around the sun gear. The planet carrier is annular, and two fixing blocks 42 are fixed on the outer circumferential surface of the planet carrier. The two fixing blocks are arranged opposite each other, and a groove is formed between the two fixing blocks. The locking block 43 is slidably arranged in the groove. The length direction of the fixing blocks and the length direction of the groove both extend radially along the planet carrier.

[0024] In this embodiment, a ratchet ring 7 is fixedly provided on the inner circumferential surface of the winding reel. A pawl is movably provided on the handle near the position of the ratchet ring. The pawl engages with the ratchet ring. Specifically, an anti-reverse adjustment mechanism 63 is provided to adjust the position of the pawl, thereby adjusting the connection state between the pawl and the ratchet ring. The anti-reverse adjustment mechanism 63 adopts existing technology, specifically referring to the patent document CN201520911840.3, which describes an anti-reverse kite winding reel. Specifically, the anti-reverse adjustment mechanism 63 is provided with a rotary switch. Turning the rotary switch causes the pawl to extend and engage with the ratchet ring, activating the anti-reverse function. Continuing to turn the rotary switch causes the pawl to retract and disengage from the ratchet ring, deactivating the anti-reverse function.

[0025] This embodiment also includes a braking mechanism, comprising a brake shoe 62 movably mounted on the handle and a brake drive block 6 rotatably mounted on the handle. The brake drive block 6 is fixedly connected to the brake handle 61, and the brake drive block abuts against the brake shoe. The braking mechanism adopts existing technology, specifically referring to the braking device for a kite reel and the kite reel patent document CN201720759959.2. When deceleration and braking are required, the user rotates the brake handle 61, causing the brake drive block 6 to rotate. Since it abuts against the brake shoe 62, the brake shoe 62 rotates outward at a certain angle with its connection point with the handle as the center, thus abutting against the outer ring of the bearing. Due to the friction between the two, the rotation speed of the winding reel decreases or even stops completely.

[0026] In this embodiment, the handle 2 includes two semi-grip members that interlock. One semi-grip member is fixedly connected with several connecting pins, and the other semi-grip member has several pin holes that correspond one-to-one with the connecting pins. The connecting pins and pin holes are interference fits, ensuring the stability of the connection between the two semi-grip members. Alternatively, the two semi-grip members can be connected by bolts. The handle 2 has a grip groove for easy handling, and a sun gear 21 is fixedly connected to the circumferential side wall of one semi-grip member.

[0027] In this embodiment, the winding reel is provided with an outer disc handle 11, and the planetary carrier is provided with an inner disc handle 23. When the winding reel and the inner gear ring are locked, the winding and unwinding operations can be performed by rotating the inner disc handle. When the winding reel and the inner gear ring are not locked, the winding and unwinding operations can be performed by rotating the outer disc handle.

[0028] See Figures 1-5 Preferably, the inner handle 23 is a foldable structure. For example, the inner handle 23 is hinged to the handle seat, and the handle seat is rotatably connected to the planetary carrier 22. This avoids the inner handle 23 from becoming an obstacle when using the outer handle 11. The outer handle 11 can be a foldable structure for easy storage.

[0029] In this embodiment, when in low-speed winding mode, the locking block 43 does not engage with the locking slot 13. At this time, the user rotates the outer handle 11 to drive the winding wheel 1 to rotate, and the outer ring 12 of the bearing and the inner ring 41 of the bearing rotate relative to each other, which can achieve low-speed winding.

[0030] When in high-speed take-up mode, the locking block 43 engages with the locking slot 13. At this time, the user rotates the inner disc handle 23 to drive the planetary carrier 22 to rotate. The planetary carrier 22 drives several planetary gears 5 to revolve around the axis of the planetary carrier 22. During this process, under the meshing action of the planetary gears 5 and the sun gear 21, the planetary gears 5 rotate synchronously, thereby driving the internal gear ring 4 to rotate. The internal gear ring 4 drives the inner bearing ring 41, the outer bearing ring 12, and the winding wheel 1 to rotate synchronously. By adjusting the gear ratio between the internal gear ring 4 and the planetary gears 5, and between the planetary gears 5 and the sun gear 21, the speed of the winding wheel 1 can be increased to achieve fast take-up.

[0031] The kite reel provided by this utility model is equipped with an internal gear ring, planetary gears and a sun gear. When the handle is held and the planetary gears are driven to rotate, the planetary gears will drive the internal gear ring to rotate. By setting a suitable gear ratio for the internal gear ring, planetary gears and sun gear, a certain transmission ratio can be achieved, so that when the planetary gears rotate around the sun gear once, the internal gear ring and the winding reel can rotate more than once, which facilitates quick line reeling.

[0032] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
