Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a badminton shuttlecock head. Background Technology

[0002] Nylon badminton shuttlecock skirts are widely accepted in the market due to their simple one-piece injection molding process, long service life, and low cost. The shuttlecock head is the most important component of a nylon badminton shuttlecock. Currently, a common method is to cut an annular groove inwards from the flat surface of the solid shuttlecock head, and then insert the connecting cylinder of the nylon skirt into the annular groove and fix it in place. The concentricity of the groove and the inserted nylon skirt is crucial to the stability of the nylon badminton shuttlecock and is also a difficult process to achieve. Another commonly used method is one-piece foam-molded shuttlecock head, which consists of a coaxial hollow cylinder and a shuttlecock head body. However, due to weight considerations, the density of one-piece foam-molded shuttlecock heads generally cannot be too high, resulting in the density of the shuttlecock head body in the hitting area not meeting the requirements of the intense movement of badminton, thus reducing the experience. One-piece foam-molded shuttlecock heads are also prone to uneven foaming, which in turn leads to poor stability of the nylon badminton shuttlecock. Utility Model Content

[0003] The purpose of this invention is to provide a badminton shuttlecock head that solves the problems existing in the prior art, enabling the shuttlecock skirt and the head body to be firmly connected without glue, and avoiding the detachment phenomenon caused by errors in glue application.

[0004] To achieve the above objectives, the present invention provides the following solution: The present invention provides a badminton shuttlecock head, including a shuttlecock head body, wherein the shuttlecock head body includes a connecting end and a shuttlecock head end;

[0005] The connecting end is a hollow cylinder coaxial with the shuttlecock head end. The inner cavity of the connecting end is used for inserting a connecting cylinder for the shuttlecock skirt. The shuttlecock skirt includes, but is not limited to, an integrally molded nylon shuttlecock skirt. The inner wall of the connecting end near the shuttlecock head end is provided with an annular cut. The annular cut is used for inserting an overhang on the surface of the connecting cylinder, thereby allowing the connecting end and the shuttlecock skirt to be fixedly connected without glue.

[0006] The ball head end has a hemispherical or spherical notch structure;

[0007] The central axes of the connecting end and the ball end coincide, and the connecting end and the ball end are fixedly connected after being formed.

[0008] Preferably, the connecting end has a hollow structure.

[0009] Preferably, the spindle head end has a first central hole extending through its axis, and the shuttlecock skirt and the connecting cylinder have a second central hole extending through their axes.

[0010] Preferably, a whistle is installed at the center of the first or second central hole.

[0011] Preferably, the connecting end is an integrally foamed structure.

[0012] Preferably, the connecting end is a structure further processed from an integrally foamed sheet or cylinder.

[0013] Preferably, both the connecting end and the ball end are transparent; a light-emitting diode is installed inside the connecting end, and the light-emitting diode is used to emit light to the outside through the connecting end and the ball end.

[0014] Preferably, the material of the ball head includes, but is not limited to, natural cork, synthetic cork, and foam material.

[0015] Preferably, the surface of the ball end is coated with a coating or a PU foam layer.

[0016] Preferably, the surface of the ball head body is covered with a PU leather layer.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] 1. The secure connection between the badminton shuttlecock skirt and the shuttlecock head relies entirely on the secure connection between the connecting cylinder of the badminton shuttlecock skirt and the shuttlecock head body. The badminton shuttlecock skirt includes, but is not limited to, one-piece molded nylon badminton skirts. In the prior art, although the consistency of one-piece injection molded nylon badminton skirts is very good, the coaxiality of the connecting groove on the surface of the shuttlecock head body, and the concentricity of the entire nylon badminton shuttlecock when the connecting cylinder is inserted into the connecting groove, will decrease, thus leading to instability of the nylon badminton shuttlecock. The connecting end of the shuttlecock head body disclosed in this utility model is a hollow cylinder, the inner diameter of which matches the outer diameter of the connecting cylinder of the nylon badminton skirt. The connecting end and the shuttlecock head end are molded separately, which can ensure their respective consistency and guarantee the consistency and concentricity after a secure connection.

[0019] 2. The inner cavity of the connecting end is used for the insertion of the connecting cylinder with the badminton shuttlecock skirt. The badminton skirt includes, but is not limited to, a one-piece molded nylon badminton skirt. The inner wall of the connecting end near the shuttlecock head is provided with an annular cut. The annular cut is used for the inverted snap fastener on the surface of the connecting cylinder to be inserted, thereby making the nylon badminton skirt and the shuttlecock head body firmly connected without glue. Not using glue can not only save glue usage costs, but also avoid the phenomenon of detachment caused by glue application errors.

[0020] 3. The connecting end adopts a hollow structure, which can reduce the weight of the connecting end and ensure that the weight of the shuttlecock head body meets the needs of badminton.

[0021] 4. A first central hole is formed through the axis of the shuttlecock head end, and a second central hole is formed through the axis of the shuttlecock skirt and connecting cylinder. The first and second central holes form a through airflow guide hole through which airflow can pass. A whistle can also be embedded in the first or second central hole to make the shuttlecock make a sound during flight, thereby enhancing the enjoyment of badminton.

[0022] 5. The connecting end and the ball head end of the ball head body are molded separately and then fixedly connected. Only the ball head end can be made of solid elastic material, which reduces the amount of material used to ensure the elastic performance of the ball head body, thereby reducing the weight of the ball head body and reducing costs.

[0023] 5.1 Natural cork is chosen as the elastic material. Natural cork is the elastic material that best meets the standards for badminton shuttlecock use. Of course, the cost is also particularly high. Natural cork is only used in the head of the shuttlecock to reduce the cost of using cork.

[0024] 5.2 The elastic material is made of synthetic cork. Synthetic cork is made by mixing and curing glue with natural cork chips. Because of its weight, it makes the shuttlecock head too heavy. Synthetic cork is only used at the head end, which greatly reduces the proportion of synthetic cork material and allows the weight of the shuttlecock head to be controlled within the range that is suitable for badminton.

[0025] 5.3 The elastic material is made of foam. The density of the foam material at the shuttlecock head can be foamed according to the elasticity and weight of the shuttlecock head to ensure that the elasticity and weight of the shuttlecock head meet the requirements of badminton.

[0026] 6. Both the connecting end and the ball end are made of transparent material; LEDs are installed at the connecting end, and the LEDs can emit light through the connecting end and the ball end, making it convenient for nighttime use. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The purpose of this invention is to provide a badminton shuttlecock head that solves the problems existing in the prior art, enabling the shuttlecock skirt and the head body to be firmly connected without glue, and avoiding the detachment phenomenon caused by errors in glue application.

[0041] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1 to 4 As shown, this utility model provides a badminton shuttlecock head. The head body includes a connecting end 1 and a head end 3. The connecting end 1 is a hollow cylinder coaxial with the head end 3. The inner cavity of the connecting end 1 is used for inserting a connecting cylinder 5 that connects to the shuttlecock skirt 4. The shuttlecock skirt 4 includes, but is not limited to, an integrally formed nylon shuttlecock skirt 4, wherein the inner diameter of the connecting end 1 matches the outer diameter of the connecting cylinder 5. The inner wall of the connecting end 1 near the head end 3 is provided with an annular cut 2, which is used for inserting into the connecting cylinder 5. The inverted buckle 6 on the circumferential surface is snapped into it. The inverted buckle 6 is in the form of a ring structure, or it is composed of multiple snap-fit ​​blocks. The snap-fit ​​blocks are evenly distributed along the circumference of the connecting cylinder 5 to ensure that the weight distribution of the badminton skirt is uniform. The snap-fit ​​blocks form a ring structure. This allows the connecting end 1 and the badminton skirt 4 to be fixedly connected even without glue. The shuttlecock head end 3 is hemispherical or spherical. The central axes of the connecting end 1 and the shuttlecock head end 3 coincide, and the connecting end 1 and the shuttlecock head end 3 are fixedly connected after being formed. The entire shuttlecock relies on the connection between the connecting cylinder 5 of the shuttlecock skirt 4 and the shuttlecock head body. It should be noted that the connecting cylinder 5 is located on the side of the shuttlecock skirt 4 closest to the shuttlecock head body and is coaxially aligned with the skirt. Furthermore, the end of the connecting cylinder 5 facing away from the skirt is capped with a bottom plate. In existing technology, although the consistency of the one-piece injection-molded nylon skirt is very good, if the coaxiality of the connecting groove on the surface of the shuttlecock head body is poor, the concentricity of the entire nylon shuttlecock will decrease when the connecting cylinder 5 is inserted into the connecting groove. This leads to instability in the entire nylon shuttlecock. The shuttlecock head disclosed in this utility model has a connecting cylinder 5 for connecting the shuttlecock skirt 4 inserted into the inner cavity of the connecting end 1. Since the inner wall of the connecting end 1 near the shuttlecock head end 3 is provided with an annular cut, the inverted buckle 6 on the circumferential surface of the connecting cylinder 5 is fastened into the annular cut 2, so that the connecting cylinder 5 of the shuttlecock skirt 4 can be fixedly connected to the shuttlecock head body without the use of glue. Not using glue can not only save the cost of glue, but also avoid the phenomenon of detachment caused by errors in glue application.

[0043] In this embodiment, the badminton skirt is a one-piece molded nylon badminton skirt 4; the nylon badminton skirt 4 is injection molded in one piece, one end of which is a connecting cylinder 5. The surface of the connecting cylinder 5 is provided with an undercut 6. When the connecting cylinder 5 is inserted into the inner cavity of the connecting end 1, the undercut 6 on the surface of the connecting cylinder 5 snaps into the annular cut 2 of the connecting end 1 and is firmly connected; the nylon badminton skirt 4 and the shuttlecock head body are firmly connected without the use of glue.

[0044] In this embodiment, the badminton shuttlecock skirt is a three-section badminton shuttlecock skirt 7; the three-section badminton shuttlecock skirt 7 is formed by inserting multiple feathers into the feather tubes of the three-section badminton shuttlecock artificial feather frame and fixing them in place; the artificial feather frame is integrally injection molded and includes multiple feather tubes, with feather insertion holes inside the feather tubes; the other end of the feather frame is a connecting cylinder 5, and the surface of the connecting cylinder 5 is provided with an inverted buckle 6. When the connecting cylinder 5 is inserted into the inner cavity of the connecting end 1, the inverted buckle 6 on the surface of the connecting cylinder 5 snaps into the annular cut 2 of the connecting end 1 and is firmly connected; the three-section badminton shuttlecock skirt 7 is firmly connected to the shuttlecock head body without the use of glue.

[0045] In this embodiment, the badminton skirt is a shuttlecock skirt 8 without a coil; the shuttlecock skirt 8 without a coil consists of multiple feathers inserted into the feather insertion tubes of the shuttlecock artificial connector without a coil and fixedly connected; the artificial connector is integrally injection molded and includes multiple feather insertion tubes with feather insertion holes inside; the other end of the artificial connector is a connecting cylinder 5, and the surface of the connecting cylinder 5 is provided with an inverted buckle 6. When the connecting cylinder 5 is inserted into the inner cavity of the connecting end 1, the inverted buckle 6 on the surface of the connecting cylinder 5 snaps into the annular cut 2 of the connecting end 1 and is firmly connected; the shuttlecock skirt 8 without a coil is firmly connected to the shuttlecock head body without the use of glue.

[0046] In this embodiment, the badminton skirt is a badminton skirt 9 with a connector; the badminton skirt 9 with a connector is made by inserting multiple feathers into the feather insertion tube of the artificial connector of the badminton shuttlecock with connector and fixing them together; the artificial connector is integrally injection molded and includes multiple feather insertion tubes with feather insertion holes inside; the other end of the artificial connector is a connecting cylinder 5, and the surface of the connecting cylinder 5 is provided with an inverted buckle 6. When the connecting cylinder 5 is inserted into the inner cavity of the connecting end 1, the inverted buckle 6 on the surface of the connecting cylinder 5 snaps into the annular cut 2 of the connecting end 1 and is firmly connected; the badminton skirt 8 without coils is firmly connected to the shuttlecock head body without the use of glue; then two coils are hooked on the shaft of the badminton shuttlecock with connectors, and multiple coats of glue are applied to the coils. After the glue on the coils cures, the coils are fixed.

[0047] In this embodiment, the connecting end 1 and the ball end 3 are formed separately, which can ensure their consistency and guarantee the consistency and concentricity after a firm connection.

[0048] In one specific implementation, the connecting end 1 is a hollow structure, which can reduce the weight of the connecting end 1 and ensure that the weight of the shuttlecock head body meets the needs of badminton.

[0049] In one specific embodiment, a first central hole is provided through the axis of the shuttlecock end 3 along its axial direction, and a second central hole is provided through the axis of the shuttlecock skirt 4 and the connecting cylinder 5 along its axial direction. The first central hole and the second central hole form a through airflow guide hole, through which airflow can pass, thereby reducing wind resistance.

[0050] In one specific embodiment, a whistle is installed at the axis of the first or second center hole, which can make the shuttlecock make a sound during flight, thereby increasing the enjoyment of badminton.

[0051] In one specific embodiment, the connecting end 1 is an integrally foamed structure. Alternatively, the connecting end 1 is a structure further processed from an integrally foamed cylinder to ensure the integrity of the connecting end 1 and thus ensure the connection strength between the connecting end 1 and the connecting cylinder 5.

[0052] In one specific embodiment, both the connecting end 1 and the ball end 3 are transparent; a light-emitting diode is installed inside the connecting end 1, which is used to emit light through the connecting end 1 and the ball end 3, making it convenient for nighttime use.

[0053] In one specific embodiment, since the connecting end 1 and the ball end 3 of the ball head body are formed separately and then fixedly connected, only the ball end 3 can be made of solid elastic material, which reduces the amount of material used to ensure the elastic performance of the ball head body, thereby reducing the weight of the ball head body and reducing costs; in this embodiment, the material of the ball end 3 includes, but is not limited to, natural cork, synthetic cork and foam material. Preferably, the shuttlecock head end 3 is made of natural cork. Natural cork is the most suitable elastic material for badminton use, but it is also very expensive. Using natural cork only in the shuttlecock head end 3 reduces the amount of natural cork used, thereby reducing the cost. Alternatively, the shuttlecock head end 3 could be made of synthetic cork. Synthetic cork is made by mixing and curing glue with natural cork shavings, resulting in a heavier weight and making the shuttlecock head too heavy. Using synthetic cork only in the shuttlecock head end 3 greatly reduces the proportion of synthetic cork material, thus keeping the weight of the shuttlecock head within the range suitable for badminton. Alternatively, the shuttlecock head end 3 could be made of foam material. The density of the foam material can be adjusted according to the elasticity and weight of the shuttlecock head end 3 to ensure that the elasticity and weight of the shuttlecock head meet the requirements of badminton.

[0054] In one specific embodiment, the surface of the ball end 3 is coated with a coating or a PU foam layer to protect the ball end 3 from damage when subjected to repeated impacts.

[0055] In one specific embodiment, the surface of the ball head body is covered with a PU leather layer to protect the ball head body from damage when repeatedly struck.

[0056] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0057] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model.
