Description

Technical Field

[0001] This utility model relates to the field of kite winding reel technology, specifically to a folding handle type kite winding reel. Background Technology

[0002] During kite flying, the kite reel is a crucial tool, enabling the flexible winding and unwinding of the kite line. Currently, kite reels typically consist of an inner reel for gripping and an outer reel that rotates coaxially with it for winding the line. Users hold the inner reel with one hand and turn the outer reel with the other to control the line winding. To facilitate operation, a crank is usually attached to the outer reel for control. However, as the kite's altitude and wind conditions change, the outer reel's rotation speed becomes relatively high during line winding, posing a certain safety risk and requiring limitations. Furthermore, the crank in existing kite reels is often vertically positioned perpendicular to the side of the outer reel, making the reel difficult to store during transport, taking up considerable space, and increasing the risk of handle damage, causing significant inconvenience for both transport and use. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology and provide a folding handle type kite winding reel.

Correspondingly, the inner wheel is provided with a handle receiving hole adapted to the foldable handle, and the foldable handle can be inserted into the handle receiving hole. The foldable handle includes a handle body, a connecting core, a return spring, and a fastening nut. One end of the connecting core is rotatably installed on the handle seat, and the handle body is fitted onto the other end of the connecting core. The return spring is placed inside the handle body and fitted onto the connecting core, and is pressed and limited by the fastening nut.

[0005] The aforementioned foldable handle facilitates the storage of the kite reel and prevents damage to the handle during transportation. At the same time, when the foldable handle is folded and placed in the handle receiving hole, the outer and inner reels are locked together, preventing the outer reel from rotating continuously, which is beneficial for the kite's flight.

[0006] Furthermore, the handle seat is fixedly mounted on the inner rim of the outer wheel and integrally formed therewith. It has a fixing hole and a clearance groove, which are interconnected and the clearance groove faces the inner wheel opening. The central axis of the fixing hole is perpendicular to the outer wheel surface, and the bottom end of the fixing hole is also provided with a transverse rotating shaft hole that communicates with it. The transverse rotating shaft hole is also connected to the clearance groove, and the opening width of the clearance groove is smaller than the diameter of the fixing hole.

[0009] Furthermore, a spring holder extending towards the gripping part is fixedly provided in the mounting hole, and a limiting groove is provided between the spring holder and the inner sidewall of the mounting hole, with the lower end of the aforementioned reset spring abutting against the limiting groove.

[0010] Furthermore, the connecting core is T-shaped, with its horizontal section rotatably installed in the aforementioned horizontal pivot hole, its vertical section able to swing in the aforementioned clearance groove, and coaxially extending into the mounting hole of the aforementioned handle body and the return spring. Its end is provided with an external thread, and the aforementioned fastening nut is threaded from the gripping end of the mounting hole to the connecting core, pressing against the upper end of the return spring.

[0011] Furthermore, the connecting core is made of metal or plastic.

[0012] Furthermore, the inner wheel is also provided with a locking seat, located on the end side of the handle receiving hole near the outer wheel, and on the same central axis as the handle receiving hole; the width of the slot on the locking seat is adapted to the aforementioned connecting core.

[0013] Furthermore, the handle receiving hole on the inner wheel is a simulated cavity, which can fit tightly with one of the long diameter ends of the grip portion in the handle body; the handle receiving hole is also provided with a through hole at the position corresponding to the grip portion of the handle body.

[0014] Furthermore, when the foldable handle is in the folded state, it is perpendicular to the outer wheel surface and can rotate around its own axis while rotating with the outer wheel; when the foldable handle is in the folded state, it is relatively parallel to the outer wheel surface, and its handle body is embedded in the handle receiving hole on the inner wheel, forming a relative lock between the inner wheel and the outer wheel.

These terms are only used to facilitate the description of the structural relationship of the components in this utility model and do not specifically mean that any component in this utility model must have a specific orientation or be constructed and operated in a specific orientation. They should not be construed as limitations on this utility model.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: Example 1, like Figures 1 to 3 As shown, a folding handle type kite reel includes an inner wheel 2 and an outer wheel 1 that rotates relative to and is coaxially fitted around its outer ring. The rotational connection between the two can be achieved using existing structures, which will not be elaborated here. A handle seat 5 is fixedly mounted on the outer wheel 1, located on one side of its inner wheel rim, and integrally formed with it. The handle seat 5 has a fixing hole 51 and a clearance groove 52. The fixing hole 51 is located on the top surface of the handle seat 5 away from the outer wheel surface, and is cut downwards perpendicular to the outer wheel surface. Its bottom end has a transverse pivot hole 53 communicating with it. (Refer to...) Figure 7 As shown, both are in an inverted T shape; a clearance groove 52 is opened on the side wall of the fixing hole 51 facing the inner wheel 2, which communicates with it. The opening width of the clearance groove 52 is smaller than the diameter of the fixing hole 51. At the same time, the clearance groove 52 is also connected to the transverse rotating shaft hole 53, and the bottom surface of its opening is flush with the bottom surface of the transverse rotating shaft hole 53.

[0019] A foldable handle 3, capable of folding towards the inner wheel 2, is rotatably mounted on the handle base 5. Figures 4 to 6As shown, the foldable handle 3 includes a handle body 31, a connecting core 32, a return spring 33, and a fastening nut 34. The connecting core 32 is T-shaped and made of metal (mostly copper) or plastic. Its horizontal section is rotatably installed in the corresponding horizontal pivot hole 53, while its vertical section can swing within the clearance groove 52 and the fixing hole 51. The handle body 31 includes a gripping part 311 and a limiting part 312. The gripping part 311 is disposed at the upper end of the limiting part 312, fixedly connected and integrally formed. Its shape is rugby ball-shaped, which conforms to ergonomics and is easy to grip and use. The lower end of the limiting part 312 is provided in the form of a boss, which is adapted to the aforementioned fixing hole 51. The handle body 31 is provided with a through mounting hole 313 along the central axis of the limiting part 312. The diameter of the end of the hole 313 located at the gripping part 311 is larger than the diameter of the end of the hole 312 located at the limiting part 312. The mounting hole 313 located at the limiting part 312 is adapted to the vertical section of the aforementioned connecting core 32. A coaxial spring holder 314 is fixedly disposed inside the mounting hole 313, which forms a limiting groove with the mounting hole 313. The handle body 31 is coaxially mounted to the vertical section of the connecting core 32 from its limiting end through the mounting hole 313; the return spring 33 is installed inside the mounting hole 313 of the handle body 31 from the gripping end side of the mounting hole 313, coaxially mounted to the connecting core 32, and its lower end is mounted to the spring holder 314, abutting against the limiting groove; the vertical section end of the connecting core 32 is provided with external threads, and the fastening nut 34 is threaded to the connecting core 32 from the gripping end side of the mounting hole 313, and the upper end of the return spring 33 abuts against the bottom end face of the fastening nut 34, thereby forming a rebound embedded structure for the foldable handle 3.

[0020] The inner wheel 2 is provided with a handle receiving hole 4 that is adapted to the foldable handle 3. At the same time, a locking seat 6 is also fixed on the side wall of the inner wheel 2 facing the foldable handle 3. It is located on the end side of the handle receiving hole 4 near the outer wheel 1, and is on the same center line as the length direction of the handle receiving hole 4. It is formed by two mutually symmetrically spaced limiting protrusions, and the width of its slot is equal to the diameter of the vertical section of the connecting core 32.

[0021] In a further optimized technical solution, two guide protrusions are fixedly provided on the handle seat 5, which are symmetrically located on both sides of the opening of the clearance groove 52 and extend horizontally toward the inner wheel side, with their outer ends being chamfered.

[0022] The specific operating principle is as follows: (Refer to...) Figure 8As shown, in the folded state, the handle body 31 of the foldable handle 3 is housed in the handle receiving hole 4, and its connecting core 32 is engaged in the locking seat 6, forming a double locking state and improving the locking stability of the inner and outer wheels. When it is necessary to straighten the foldable handle 3 (the foldable handle 3 is perpendicular to the outer wheel surface) for use, by inserting a finger into the mounting hole 313 on the handle body 31 and pulling it outward, the foldable handle 3 can swing along the guide protrusion 54 in the relief groove 52 of the handle seat 5 until it reaches the position of the fixing hole 51. Then, under the tension of the return spring 33, the lower end of the limiting part 312 of the handle body 31 automatically inserts downward into the fixing hole 51, forming a limit. The user can then grasp the gripping part 311 of the handle body 31 to drive the outer wheel 1 to rotate, making it more stable during use and preventing it from swinging back and forth. When folding and storing, the user holds the handle body 31 and pulls it upward, which compresses the return spring 33. Then, the user can turn it towards the inner wheel to fold the handle 3. During this process, the handle body 31 can be rotated so that the long axis of its grip part 311 is perpendicular to the inner wheel 2, and it is perfectly inserted into the corresponding handle receiving hole 4 to complete the storage. This can avoid damage to the handle during transportation.

[0023] Example 2, A folding handle type kite reel includes an inner wheel 2 and an outer wheel 1 that rotates relative to and coaxially sleeves on the outer ring of the inner wheel 2. The outer wheel 1 has a handle seat 5, and a foldable handle 3 is rotatably mounted on the handle seat 5. Correspondingly, the inner wheel 2 has a handle receiving hole 4. Its overall structure is largely the same as the technical solution described in Embodiment 1 above, the difference being that: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 9 and Figure 10 As shown, the handle receiving hole 4 on the inner wheel 2 is a simulated cavity, which can fit tightly with one of the long-diameter ends of the grip portion 311 of the handle body 31 and the limiting portion 312 on the same side. The two have the same shape. At the same time, the simulated cavity is provided with a through hole corresponding to the position of the grip portion 311 of the handle body 31, which facilitates the perfect insertion of the long-diameter end of the grip portion 311. The perfect fit between the handle body 31 and the simulated cavity can further improve the locking firmness between the inner wheel 2 and the outer wheel 1.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Finally, the above description is not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
