Description

Technical Field

[0001] The utility model relates to the technical field of kite winding wheels, in particular to an anti-reversal kite winding wheel. Background Art

[0002] Flying a kite is one of the most popular leisure activities. In the process of flying a kite, the kite winding reel is a very important tool. Usually, one hand holds the winding reel and the other hand controls the reeling and releasing of the line. When the kite reaches a certain height and no longer needs to release the line, the locking mechanism on the kite winding reel is used to lock the line release. At this time, people can walk or run to control the position of the kite in the sky, which increases the entertainment of flying a kite.

[0003] There are various structures of kite reels on the market, most of which are composed of a hand-held wheel and a winding wheel, which can rotate relatively flexibly to achieve line release and line reeling. After the locking mechanism on the existing kite reel is locked, the reel is usually completely locked, so that the reel can neither rotate forward nor reverse, that is, the line reeling and line release operations cannot be performed after locking. However, in the actual kite flying process, sometimes it is only necessary to lock the line reeling or line release, and there is no need to completely lock the reel. For example, after the kite reaches a certain height, the line release is locked but the line reeling operation can be performed at any time. The existing kite reel needs to constantly manipulate the locking structure to achieve the line reeling and line release operations, which is cumbersome to operate and reduces the entertainment of kite flying to a certain extent. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the above-mentioned existing background technology and provide an anti-reversal kite winding wheel, which can only lock the reeling or unreeling. During the kite flying process, it is easy to use, reduces the operation links, and increases the entertainment of flying the kite.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-reversal kite reel, including a winding wheel and a hand-held wheel coaxially installed inside the winding wheel, and the winding wheel can rotate clockwise or counterclockwise relative to the hand-held wheel. The hand-held wheel is equipped with an anti-reversal mechanism, and the anti-reversal mechanism includes an outer knob, an ejection rod, and a ratchet fixedly arranged on the outer side wall of the ejection rod, wherein the outer knob and the ejection rod are relatively fixedly connected, and a positioning unit is arranged between the outer knob and the hand-held wheel; the inner side wall of the winding wheel is provided with a ratchet structure that circles the circumference thereof and is adapted to the ratchet.

[0006] Furthermore, the positioning unit includes a spring positioning bead and a corresponding positioning groove, wherein the spring positioning bead is detachably fixed on the hand-held wheel within the rotation range of the above-mentioned outer knob, and the bead head points to the outer knob; two spaced-apart positioning grooves are provided on the side wall of the outer knob facing the spring positioning bead, which are arranged in a circle and are adapted to the bead head of the spring positioning bead.

[0007] Furthermore, the spacing distance between the centers of the two positioning grooves is the relative distance for the pawl to swing out and swing in.

[0008] Furthermore, the ratchet structure uses a one-way internal tooth ratchet; the above-mentioned external knob cooperates with the ejection rotating rod to change the swing-in and swing-out states of the ratchet pawl and relatively lock them.

[0009] When the pawl in the anti-reversal mechanism is in a swing-out state, it can limit the winding wheel from rotating counterclockwise but not clockwise; when the pawl in the anti-reversal mechanism is in a swing-in state, it neither limits the winding wheel from rotating counterclockwise nor clockwise.

[0010] Furthermore, the upper end of the ejector rotating rod is a square boss structure, and correspondingly, the outer knob is provided with a square hole at the center position facing the ejector rotating rod, and the upper end of the ejector rotating rod is inserted into the square hole of the outer knob and relatively fixed by screws.

[0011] Furthermore, a mounting hole is provided on the hand-held wheel disc, and the ejector rotating rod is installed in the interlayer of the hand-held wheel disc, with its upper end passing upward through the mounting hole and being rotatably installed, and its lower end being rotated downward and inserted into the opposite side wall of the hand-held wheel disc.

[0012] Furthermore, the outer edges of the rotation range of the outer knob on the hand-held wheel are all protruding upwards.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and good use effect, and can control the one-way relative rotation of the hand-held wheel and the winding wheel, and can only control the line release or line reel. After the kite reaches a certain height, the line release can be locked in one direction, but the line reel can be reeled in at any time, and the winding wheel will not reverse. The utility model is simple to operate, easy to use, and increases the entertainment of kite flying. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0026] like Figure 1 and Figure 2 As shown, an anti-reversal kite winding wheel comprises a winding wheel disc 1 and a hand-held wheel disc 2 coaxially mounted on the inner ring side of the winding wheel disc 1, wherein the winding wheel disc 1 can rotate clockwise or counterclockwise relative to the hand-held wheel disc 2, wherein the winding wheel disc 1 comprises an outer wheel and an inner wheel integrally formed, the two are coaxially arranged, and the thickness of the inner wheel is less than that of the outer wheel; a U-shaped cross-sectional ring groove 12 is provided on the outer periphery of the outer wheel, which is used for winding the kite flying line, and an annular reinforcing rib is also provided on the outer side wall of the ring groove 12 to enhance the strength of the ring groove 12; the winding wheel disc 1 and the hand-held wheel disc 2 are connected in a rolling rotation manner to reduce the relative friction between the two and improve the use feel; at the same time, a ratchet 11 is provided on the inner side wall of the inner wheel of the winding wheel disc 1 to be around the circumference thereof, and the ratchet 11 adopts a unidirectional internal tooth ratchet. A rotating handle 13 is rotatably mounted on one side wall of the outer wheel of the winding wheel 1, which is convenient for an operator to hold and drive the rotating winding wheel 1.

[0027] Combination Figures 3 to 7 As shown, the hand-held wheel 2 is formed by combining an upper clamping cover 23 and a lower clamping cover 24 and fixing them by screws, wherein a grip 21 for easy gripping and two gripping holes 22 separated by the grip 21 are formed in the middle part, so that the operator can hold the hand-held wheel 2 conveniently, and the outer periphery of the hand-held wheel 2 is just nested and engaged with the inner wheel of the winding wheel 1. In order to realize the one-way rotation locking between the winding wheel 1 and the hand-held wheel 2, an anti-reversal mechanism 3 is provided on the hand-held wheel 2, which is located at the lower end side of the grip 21; the anti-reversal mechanism 3 includes an outer knob 31, an ejection rotating rod 32, a ratchet 33 fixedly arranged on the outer side wall of the ejection rotating rod 32, and a positioning unit, wherein a square hole 311 is provided at the center position of the bottom surface of the outer knob 31, and the upper end of the ejection rotating rod 32 is arranged in a square boss structure. Corresponding to the installation position of the anti-reversal mechanism 3, a through mounting hole 25 is provided on the upper clamping cover 23 in the hand-held wheel 2, and a positioning hole is provided next to the mounting hole 25, both of which are located within the rotation radius of the outer knob 31 to reduce the occupied space; the above-mentioned ejection rotating rod 32 is installed between the upper clamping cover 23 and the lower clamping cover 24, and its upper end is installed upward through the mounting hole 25 and can be rotated, and the square boss-shaped upper end is inserted into the square hole 311 on the bottom surface of the outer knob 31, and is connected and fixed by screws, so that the ejection rotating rod 32 can rotate synchronously with the outer knob 31, and the lower end of the ejection rotating rod 32 is rotated downward and inserted into the corresponding insertion hole 26 on the lower clamping cover 24.

[0028] The positioning unit includes a spring positioning bead 34 and its corresponding positioning groove 312, wherein the spring positioning bead 34 is fixedly installed in the positioning hole by means of interference fit, and its bead head protrudes from the outer surface of the upper clamp cover 23, and the spring positioning bead 34 is detachably connected, which is convenient for subsequent maintenance and replacement. Correspondingly, the positioning groove 312 is provided on the bottom surface of the outer knob 31 facing the spring positioning bead 34, and there are two of them, which are spaced apart from each other and arranged in a circle around the center of the outer knob 31. The angle between the centers of the two positioning grooves 312 is exactly the rotation angle of the ratchet 33 for swinging in and out, and the spacing distance between the two is the relative distance of the ratchet 33 for swinging in and out; the bead head of the spring positioning bead 34 can just fit into the corresponding positioning groove 312 to complete the positioning.

[0029] According to a further optimized technical solution, the outer edges of the rotation range of the outer knob on the upper clamping cover 23 in the hand-gripped wheel 2 are all raised upward to form a limit protrusion 27, which is used to ensure the stable rotation of the outer knob 31 without offset and affecting the use.

[0030] When in use, the pawl 33 is matched with the ratchet wheel 11, and the outer knob 31 cooperates with the ejection rod 32 to change the swing-in and swing-out states of the pawl 33 and relatively lock them. When the pawl 33 in the anti-reversal mechanism 3 is in the swing-out state, it can limit the winding wheel 1 from rotating counterclockwise but not from rotating clockwise; when the pawl 33 in the anti-reversal mechanism 3 is in the swing-in state, it neither limits the winding wheel 1 from rotating counterclockwise nor from rotating clockwise.

[0031] When flying a kite, two working states can be achieved, as follows:

[0032] 1. Use the anti-reverse mechanism 3 to reel in the line. At this time, the pawl 33 is swung out by turning the outer knob 31 to enable the anti-reverse function. Due to the cooperation between the pawl 33 and the ratchet wheel 11, the line can be reeled in without loosening the line due to rotation.

[0033] 2. The anti-reversal mechanism 3 is not used for reeling and releasing the line. At this time, the outer knob 31 is turned to swing the ratchet 33 in, and the anti-reversal function is disabled. The user can reel and release the line at any time according to the needs of the user by shaking the rotating handle 13 on the winding wheel 1, thereby controlling the flying height and posture of the kite.

[0034] The related technical features that have not been mentioned or described in detail in the technical solutions described in the above embodiments can be achieved by adopting or referring to the related technical solutions in the prior art.

[0035] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
