[0002] A combat ball is a piece of equipment specifically designed for combat training, typically used to improve an athlete's reaction speed, coordination, and striking accuracy. Currently, the elastic cords on combat balls are usually attached to a headband. When trainees want to adjust the length of the cords, they need to untie and re-tie them, which is not only time-consuming, but also causes unused cords to dangle from the headband, hindering training. Utility Model Content

[0003] To address the problem of cumbersome adjustment of the elastic cord length in existing combat balls, this application provides a combat ball with an adjustable elastic cord length. The specific technical solution of this application is as follows:

[0004] A combat ball with adjustable elastic cord length includes: a headband, a hitting ball, and an elastic cord. The combat ball also includes a cord winding mechanism disposed at the front end of the headband. The cord winding mechanism includes a winding post. One end of the elastic cord is wound around the winding post, and the other end is connected to the hitting ball. The combat ball adjusts the length of the elastic cord between the winding post and the hitting ball by increasing or decreasing the number of turns of the elastic cord on the winding post.

[0005] Furthermore, the winding mechanism includes a housing, which includes a rear housing and a front housing. The winding post is disposed in the housing. The rear housing is mechanically connected to the headband. The front end of the front housing is provided with a circular hole, and the elastic rope is connected to the winding post located in the housing through the circular hole.

[0006] Furthermore, the shape of the outer shell includes, but is not limited to, spherical, cylindrical, prismatic, disk-shaped, star-shaped, and tetrahedral.

[0007] Furthermore, the winding mechanism also includes a tensioning member disposed between the winding post and the front housing. The tensioning member is provided with a plurality of compression plates, and gaps are provided between the compression plates. The elastic rope is connected to the winding post through the gaps.

[0008] Furthermore, the winding post passes through the outer shell from one side and is rotatably mounted on the outer shell. A knob is provided on one side of the winding post, and a limit block is provided on the other side. The knob and the limit block are located on the two sides of the outer shell, respectively.

[0009] Furthermore, the limiting block is a U-shaped locking block, and the winding post is provided with an annular block at one end of the U-shaped locking block, with the U-shaped locking block located between the annular block and the outer shell.

[0010] Furthermore, the winding mechanism also includes a fixing post and a kit. One end of the winding post faces the rear shell and the other end faces the front shell. The kit is fitted onto the end of the winding post facing the front shell. The fixing post passes through the winding post and is located between the kit and the front shell. A support seat is provided at the end of the winding post facing the rear shell.

[0011] Furthermore, the headband includes a support plate and a support column, one end of which is connected to the support plate, and the other end of which passes through the rear shell and is rotatably connected to the rear shell.

[0012] Furthermore, the support column has a threaded portion at one end that penetrates the rear shell, and the rear shell has a placement groove. The threaded portion is placed in the placement groove. The headband also includes a bearing and a nut placed in the placement groove.

[0027] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of this application, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting it.

[0028] like Figure 1 and Figure 7 As shown, a combat ball with an adjustable elastic cord length includes: a headband 1, a striking ball 2, and an elastic cord 3. The combat ball also includes a cord winding mechanism 4, which is located at the front end of the headband 1. The cord winding mechanism 4 includes a winding post 5. One end of the elastic cord 3 is wound around the winding post 5, and the other end is connected to the striking ball 2. The combat ball adjusts the length of the elastic cord 3 between the winding post 5 and the striking ball 2 by increasing or decreasing the number of turns of the elastic cord 3 on the winding post 5. The winding post 5 can be set horizontally forward, laterally, or vertically.

[0029] In one embodiment, the winding mechanism 4 includes a housing 6, which comprises a rear housing 7 and a front housing 8. The front housing 8 and the rear housing 7 are fixedly connected by threads, and the winding post 5 is disposed within the housing 6. The rear housing 7 is mechanically connected to the headband 1, and the rear housing 7 can be fixedly connected to the headband 1 or movably connected to the headband 1. The front end of the front housing 8 is provided with a circular hole 9, through which the elastic rope 3 extends from the outside into the housing 6 and connects to the winding post 5 located within the housing 6. The housing 6, consisting of the front housing 8 and the rear housing 7, facilitates the installation of the winding post 5 and the production of the housing 6.

[0030] As one embodiment, the shape of the outer shell 6 includes, but is not limited to, spherical, cylindrical, prismatic, disk-shaped, star-shaped, and tetrahedral shapes. The shape of the outer shell 6 is designed according to actual production needs, offering high flexibility.

[0031] As one embodiment, such as Figure 7As shown, the rope winding mechanism 4 also includes a rope tightening member 10 disposed between the winding post 5 and the front shell 8. The rope tightening member 10 has several compression plates 12, with gaps 13 between the compression plates 12. The elastic rope 3 is connected to the winding post 5 through the gaps 13. The rope tightening member 10 includes a circular ring 11 and triangular compression plates 12 arranged around the circular ring 11. The compression plates 12 are evenly distributed around the circular ring 11. When the rope tightening member 10 is installed between the front shell 8 and the rear shell 7, the front shell 8 presses down on the compression plates 12, causing the compression plates 12 to contract inwards. This reduces the width of the gaps 13 between the compression plates 12, thus tightening the elastic rope 3 located in the gaps 13 and preventing it from moving erratically.

[0032] As one embodiment, such as Figure 2 As shown, this is one arrangement of the winding post 5. The winding post 5 penetrates the outer shell 6 from one side and is rotatably mounted on the outer shell 6. A knob 14 is provided on one side of the winding post 5, and a limit block 15 is provided on the other side. The knob 14 and the limit block 15 are located on opposite sides of the outer shell 6. The winding post 5 can penetrate the outer shell 6 horizontally or vertically. For ease of production, the winding post 5 only penetrates the rear shell 7 or the front shell 8. The attached drawings of this application disclose the structure of the winding post 5 penetrating the rear shell 7. The winding post 5 is movably mounted on the outer shell 6. The elastic rope 3 can be wound and unwound by rotating the knob 14, realizing the length adjustment of the elastic rope 3. The structure is simple and the adjustment is convenient. The winding post 5 is also provided with a first small hole 16, which facilitates the horizontal fixation of the elastic rope on the winding post 5.

[0033] In one embodiment, the limiting block 15 is a U-shaped locking block. An annular block 17 is provided at one end of the winding post 5, and the U-shaped locking block is located between the annular block 17 and the outer casing 6. The U-shaped locking block allows for quick installation and removal of the winding post 5. The limiting block 15 is used to prevent one end of the winding post 5 from falling out of the outer casing 6. Therefore, the limiting block 15 can also be other structures, such as a limiting nut or a limiting post, etc.

[0034] As one embodiment, such as Figure 3As shown, this is another configuration of the winding post 5. The winding mechanism 4 also includes a fixing post 18 and a kit 19. One end of the winding post 5 faces the rear shell 7, and the other end faces the front shell 8. The winding post 5 is fixedly disposed between the front shell 8 and the rear shell 7. The kit 19 is sleeved on the end of the winding post 5 facing the front shell 8. The fixing post 18 passes through the winding post 5 and is located between the kit 19 and the front shell 8. A support seat 21 is provided at the end of the winding post 5 facing the rear shell 7. When the elastic rope 3 is wound on the winding post 5, the kit 19 is used to fix the elastic rope 3 to prevent it from loosening, and the fixing post 18 is used to prevent the kit 19 from falling off. In this case, the tensioning member 10 can be omitted from the outer shell 6. A second small hole 20 is also provided on the winding post 5, which facilitates the horizontal fixation of the elastic rope on the winding post 5.

[0035] As one embodiment, such as Figures 4 to 6 As shown, the headband 1 includes a support plate 22 and a support column 23. One end of the support column 23 is connected to the support plate 22, and the other end passes through the rear shell 7 and is rotatably connected to the rear shell 7. The support column 23 can be integrated with the support plate 22 or it can be separate from the support plate 22. During the hitting process, the hitting ball 2 rotates, which drives the elastic cord 3 to rotate, causing the elastic cord 3 to be in a twisted state. The outer shell 6 can rotate relative to the support column 23, thereby allowing the twisted elastic cord 3 to quickly return to its original position, improving the user experience.

[0036] As one embodiment, such as Figure 2 As shown, the support column 23 has a threaded portion 24 at one end penetrating the rear shell 7. The rear shell 7 has a placement groove 25, in which the threaded portion 24 is located. The headband 1 also includes a bearing 26 and a nut 27 disposed in the placement groove 25. The nut 27 is fitted onto the threaded portion 24, and the bearing 26 is fitted onto the support column 23 and located between the nut 27 and the rear shell 7. The bearing 26 improves the rotational effect of the outer shell 6 relative to the support column 23, enhances the reset effect of the elastic cord 3, and prevents the elastic cord from tangling during use. Besides accommodating the bearing 26 and nut 27, the placement groove 25 also serves as a support base 21 for supporting the winding column 5.

[0037] As one embodiment, such as Figure 3As shown, the support column 23 has a slot 31 at one end penetrating the rear shell 7. The rear shell 7 has a placement groove 25, and the slot 31 is disposed in the placement groove 25. The headband 1 also includes a bearing 26 and a retaining spring 32 disposed in the placement groove 25. The retaining spring 32 is sleeved on the slot 31, and the bearing 26 is sleeved on the support column 23 and located between the retaining spring 32 and the rear shell 7. The combat ball uses the retaining spring 32 to restrict the bearing 26 to the support column 23, which not only facilitates the installation and removal of the bearing 26 but also effectively reduces production costs. The slot 31 can also be in the shape of a small hole, in which case the retaining spring 32 is in the shape of a limiting post.

[0038] In one embodiment, the support column 23 has a screw hole 28 at one end facing the support plate 22, and the support plate 22 has a through hole 29. The support column 23 is fixedly connected to the support plate 22 by screws 30. The support column 23 is fixed to the support plate 22 by screws 30, which facilitates the production and transportation of the support plate 22.

[0039] The combat ball described in this application has a winding post 5 at the front end of the headband 1. The length of the elastic cord 3 between the headband 1 and the striking ball 2 is adjusted by winding the elastic cord 3 around the winding post 5, which can be achieved without repeatedly untying the elastic cord 3, thus improving the speed of length adjustment. The unused elastic cord 3 will be wound around the winding post 5, without affecting the trainee, making it highly practical. After the trainee stops training, the elastic cord of the combat ball can be stored in the cord winding mechanism, effectively solving the problem of elastic cord storage and preventing the elastic cord from getting tangled when the combat ball is placed down.
