Description

Technical Field

[0001] The utility model relates to the technical field of sports goods, in particular to a badminton ball. Background Art

[0002] Badminton is a popular sport. The venue for badminton is relatively large. However, for natural badminton balls made of goose or duck wing feathers, the number of geese and ducks is less than the number required for badminton sports, and the price of feathers is rising day by day, resulting in a continuous increase in the price of badminton balls. In addition, for two-piece badminton balls, including but not limited to those made of traditional two-piece natural feathers or artificial badminton balls made of artificial feathers, it is necessary to wind two coils on the feather shaft and apply glue to cure the coils. Coil winding requires additional time and material costs, and at the same time increases the weight of the badminton ball. The increase in the weight of the badminton ball will cause the badminton ball to exceed the landing point required for badminton sports.

[0003] In the prior art, a process of winding two coils on the feather shaft and applying glue to cure the coils is often adopted to produce badminton balls. For example, Chinese Patent Application for Invention CN201810232934.6, Chinese Patent Application for Invention CN201810232930.8, Chinese Patent Application for Invention CN201810232973.6, and Chinese Patent Application for Utility Model CN201820382683.5. The above production methods make the production process cumbersome and the production cycle longer, thereby increasing the production cost. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a badminton ball to solve the problem of winding two coils on the feather shaft of the badminton ball and the need for glue curing.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] The utility model provides a badminton ball, which includes feather pieces, a connecting frame and a ball head. The connecting frame is integrally formed by injection molding. The connecting frame includes a circular thin plate, a circular barrel and a plurality of feather inserting tubes. One side of the circular thin plate is connected to the circular barrel, and a plurality of feather inserting tubes are evenly arranged on the circumference of the other side of the circular thin plate. The included angle formed by any one of the feather inserting tubes and the central axis of the circular thin plate is the same;

[0007] A circular groove is arranged inward on the ball head plane of the ball head. The size of the circular groove matches the size of the circular barrel, so that the circular barrel can be inserted into the circular groove and fixedly connected;

[0008] The feather pieces are inserted into the feather inserting tubes and firmly connected.

[0009] Preferably, the number of the feather pieces is 3 to 16.

[0010] Preferably, the fluff pieces are natural feather pieces.

[0011] Preferably, the fluff pieces are artificial fluff pieces, and the artificial fluff pieces include fluff stems and blades. The fluff stems and blades of the artificial fluff pieces are of a combined structure, and the blades are made of foamed thin sheets.

[0012] Preferably, the fluff pieces are artificial fluff pieces, and the artificial fluff pieces include fluff stems and blades. The artificial fluff pieces are integrally formed by injection molding.

[0013] Preferably, the sizes of the blades on both sides of the fluff stem are different, with one side being larger and the other side being smaller.

[0014] Preferably, a plurality of air flow diversion holes are distributed on the blades of the artificial fluff pieces.

[0015] Preferably, the end of the fluff stem away from the blade is a plug-in end, and there is a clamping block for fixing the fluff stem on the plug-in end. There is a clamping hole on the fluff inserting tube, and the size of the clamping hole matches the size of the clamping block on the fluff stem. After the fluff stem is inserted into the fluff inserting tube, the clamping block is clamped into the clamping hole, and the artificial fluff piece is fixedly connected to the fluff inserting tube without the need for glue fixation.

[0016] Preferably, the length of the fluff pieces is 40 - 70 mm.

[0017] Preferably, the ball head is a light-transmitting ball head composed of light-transmitting materials. There is a receiving cavity located at the center position on the top plane of the light-transmitting ball head, and the size of the receiving cavity matches that of the light-emitting body. The light-emitting body includes a button battery, a light-emitting diode, and a switch. Wires connect the button battery, the light-emitting diode, and the switch in series. The closing and opening of the switch are the connection and disconnection of the circuit, thereby controlling the lighting and non-lighting of the light-emitting diode. When the light-emitting diode emits light, the light is transmitted from the inside of the light-transmitting ball head to the outside of the light-transmitting ball head.

[0018] The utility model has achieved the following technical effects compared with the prior art:

[0019] 1. A badminton is composed of three parts: fluff pieces, a connecting frame, and a ball head; the middle connecting frame connects the fluff pieces and the ball head together. The fluff stem is directly inserted into the fluff inserting tube of the connecting frame instead of being inserted into the inside of the ball head, and the length of the fluff stem can be shortened to 40 - 70 mm, so the gram weight of the fluff pieces can be reduced.

[0020] 2. There is no coil on the fluff stem, saving the cost of winding two coils, and there is no need to coat glue for curing the coils, further reducing the cost of the glue for the two coils. At the same time, the gram weight of the two coils and the glue on the coils is reduced.

[0021] 3. The middle connecting frame connects the ball head and the vane together to form a badminton. Moreover, the second coil is omitted and the number of vanes is also reduced. Therefore, after cutting off one vane from a natural feather, the remaining part can be cut into a second vane. Although the rachis of the second vane is thicker and the gram weight is heavier, because the number of vanes is reduced to 3 - 16 pieces and there is no coil, the gram weight of the coil and the glue on the coil does not exist either. Therefore, the gram weight of the badminton of the present utility model is correspondingly reduced, the second vane can be utilized, and this kind of ball can be used as a recreational ball.

[0022] 4. To make an artificial badminton with a traditional artificial vane in a two - section structure, the rachis of the artificial vane needs to be inserted into the ball head, and then glue is injected and cured at the intersection of the plane of the ball head and the rachis of the artificial vane. In addition, two coils need to be wound around the rachis and glue is applied and cured. In this way, due to the increase in gram weight caused by the lengthening of the rachis of the artificial vane, the gram weight of the two coils and the glue on the coils, the gram weight of the artificial badminton cannot be reduced; the biggest obstacle of the artificial badminton is that the gram weight is too heavy to meet the gram weight required for badminton sports. However, the technology of the present utility model does not require two coils, nor does it have the gram weight of the glue on the two coils. Moreover, the rachis only needs to be inserted into the vane - inserting tube of the connecting frame, and there is a clamping block on the inserting end of the artificial rachis that just snaps into the small clamping hole on the vane - inserting tube to form a firm connection.

[0023] 5. The number of vanes of the technology of the present utility model can be 3 - 16 pieces. The fewer the number of vanes, the lighter the gram weight of the vanes, and at the same time, the lower the cost with the fewer number of vanes.

[0024] 6. The vane of the present utility model is a natural vane, and one end of the rachis of the natural feather is thin and the other end is thick; after cutting off one vane from a natural feather piece, the remaining part can be cut into a second vane. In the technology of the present utility model, a 74 - mm traditional badminton vane is first made from the natural feather piece, and then on the remaining large rachis, a 58 - mm natural vane is cut. The rachis of this 58 - mm natural vane is significantly thicker than the rachis used in conventional badminton, and 16 such 58 - mm rachises cannot be inserted into one ball head; the present utility model only needs 10 natural vanes with such thick rachises to be inserted into the vane - inserting tubes of the connecting frame, which can reduce the usage quantity and length of the natural feather, enabling the badminton composed of natural feathers of the present utility model to complete flight. The implementation of this technology can improve the utilization rate of natural feather resources. After making a traditional natural badminton, the remaining natural feather rachis can also be utilized to make a natural badminton made from the second feather piece on the natural feather for people's fitness use.

[0025] 7. The artificial vane is provided with air - flow guiding holes, avoiding the problem that the existing artificial vane causes the flight trajectory of the badminton to deviate from the expected trajectory during flight due to the absence of air - flow guiding holes.

[0026] 8. The connecting frame is integrally formed by injection molding. The injection mold is designed and made by computer. The connecting frames formed by injection molding have good consistency, multiple products can be produced in one mold, improving efficiency and reducing costs.

[0027] 9. The artificial fluff pieces are integrally formed by injection molding. The injection mold is designed and made by computer. The artificial fluff pieces have good consistency, multiple products can be produced in one mold, improving efficiency and thus reducing costs.

[0028] 10. The ball head is selected as an integrally foamed ball head, multiple products can be produced in one mold, with good consistency and low cost.

[0029] 11. The light-transmitting ball head is integrally foamed and formed with a material having good light-transmitting performance. There is a receiving cavity inside the light-transmitting ball head to install a light-emitting body. The light emitted by the light-emitting diodes of the light-emitting body can be transmitted from the inside of the light-transmitting ball head to the outside of the light-transmitting ball head; it is convenient for people to use the badminton of the utility model technology even at night and in environments with poor light.

[0050] Further, the hair leaves and the hair rod of the artificial hair piece are a combined structure formed separately and then combined together. The hair leaves are made of foamed thin sheets, and the foamed thin sheets are made of PU foaming material.

[0051] Further, there is a clamping block at the insertion end of the hair rod of the artificial hair piece away from the hair leaves. There is a clamping hole on the side wall of the hair insertion tube of the connecting frame 2 with a size matching that of the clamping block. After the artificial hair piece is inserted into the hair insertion tube, the clamping block is clamped into the clamping hole and firmly connected, without the need to inject glue into the hair insertion holes.

[0052] Embodiment 3

[0053] As Figure 4 shown, this embodiment provides a badminton, including a ball head 3, a hair piece 1, and a connecting frame 2. First, a mold for integrally injection-molding the connecting frame 2 is made, with multiple products produced in one mold; the connecting frame 2 includes a circular thin plate, a circular barrel 22, and multiple hair insertion tubes 21. One side of the circular thin plate is connected to the above-mentioned circular barrel 22, and multiple hair insertion tubes 21 are evenly arranged on the circumference of the other side of the circular thin plate. The multiple hair insertion tubes 21 form the same included angle with the central axis of the circular thin plate. The number of the insertion tubes 21 is 3 - 16, and the number of the insertion tubes 21 in this embodiment is set to 6; on the ball head plane 33 of the ball head 3, a circular groove 32 is formed from the surface inward. The size of the circular groove 32 matches the size of the circular barrel 22 on one side of the circular thin plate, so that the circular barrel 22 can be inserted into the circular groove 32 and fixedly connected; then a mold for integrally injection-molding the artificial hair piece is made, with multiple products produced in one mold; the artificial hair piece is inserted into the hair insertion tubes pre-injected with glue, and after the glue is cured, they are firmly connected to each other; then a color band is wound around the surface of the ball head cylinder, and a badminton is made.

[0054] Further, there are multiple air flow guiding holes on the hair leaves of the artificial hair piece.

[0055] Further, the sizes of the hair leaves on both sides of the hair rod are different, one being larger and the other smaller.

[0056] Further, there is a clamping block at the insertion end of the hair rod of the artificial hair piece away from the hair leaves.
