Description

Technical Field

[0001] This utility model relates to a novel ball head structure for a ball head elastic cord. Background Technology

[0002] Ballbungee cords, also known as ballbungee cords, are elastic cords with ball-shaped connectors, commonly used for securing, binding, and connecting various items. They are frequently used in outdoor activities, camping, car transport, and home DIY projects. Ballbungee cords are typically made of rubber or latex, offering high elasticity and durability. Common sizes include 6 inches, 8 inches, and 9 inches, with custom lengths available. The cord diameter is usually 4mm or 5mm, and the ball diameter is 28mm or 29mm. Common colors are black and white, but custom colors are also available upon request.

[0003] The ball-head elastic ropes currently sold on the market have a very simple ball-head structure, with only two rope inlets for the two ends of the elastic rope to be threaded through and knotted for fixation. The length of the elastic rope is not adjustable, which means that users need to choose the appropriate size ball-head elastic rope according to the actual use scenario, which is somewhat inconvenient during use. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a novel ball head structure for a ball head elastic cord.

[0005] To achieve the above objectives, this utility model provides a novel ball-head structure for a ball-head elastic rope, comprising a spherical body. The spherical body has an inlet hole for the elastic rope to pass through and a return hole for the elastic rope to exit. The spherical body also has a locking groove for the free end of the elastic rope to be inserted into. The inner wall of the locking groove has multiple locking teeth that restrict the movement of the elastic rope along the long side of the locking groove. The spherical body has an anti-detachment part at the end of the locking groove away from the return hole, which prevents the free end of the elastic rope from leaving the position of the locking groove.

[0006] Furthermore, the rope inlet hole is formed on the upper hemisphere of the spherical body, the trajectory line of the rope inlet hole is "┘" shaped, the cross-section of the rope inlet hole is circular, and the cross-section of the rope inlet hole at the insertion end is larger than that at the exit end.

[0007] Furthermore, the return rope hole extends vertically through the spherical body.

[0008] Furthermore, the locking groove is vertically connected to the return rope hole.

[0009] Furthermore, there are six teeth, which are evenly distributed on both sides of the slot, and the width of each tooth increases from the opening of the slot to the bottom of the slot.

[0010] The advantages of this invention over the prior art are as follows: by improving the ball head structure of the existing ball head elastic rope, the new ball head can easily adjust the effective length of the elastic rope when used in conjunction with the elastic rope, allowing users to switch the effective length of the elastic rope according to the actual usage scenario.

[0015] like Figures 1-3 As shown in the figure, a novel ball-head structure for a ball-head elastic cord according to an embodiment of the present invention includes a spherical body 1. The spherical body 1 has an inlet hole 11 for the elastic cord to pass through and a return hole 12 for the elastic cord to exit. The spherical body 1 also has a locking groove 13 for the free end of the elastic cord to be inserted into. The inner wall of the locking groove 13 has multiple locking teeth 14, which restrict the movement of the elastic cord along the long side of the locking groove 13. An anti-detachment part 15 is formed at the end of the spherical body 1 away from the return hole 12. To prevent the free end of the elastic rope from detaching from the locking groove 13; the rope inlet hole 11 is formed on the upper hemisphere of the spherical body 1, the trajectory line of the rope inlet hole 11 is "┘" shaped, the cross-section of the rope inlet hole 11 is circular, and the cross-section of the rope inlet hole 11 at the insertion end 111 is larger than that at the exit end 112; the rope return hole 12 vertically penetrates the spherical body 1; the locking groove 13 and the rope return hole 12 are vertically connected; there are six locking teeth 14, which are evenly distributed on both sides of the locking groove 13, and the tooth width of each locking tooth 14 increases from the opening of the locking groove 13 towards the bottom of the groove.

[0016] By improving the ball head structure of existing elastic cords, this new ball head allows for easy adjustment of the effective length of the elastic cord when used in conjunction with it, enabling users to switch the effective length of the elastic cord according to actual usage scenarios.

[0017] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0018] A certain length of elastic rope is inserted through the inlet hole 11 and exited through the outlet hole 12. One end of the elastic rope is knotted to form a large-diameter end that cannot leave the outlet end 112, thus forming a fixed end. The free end of the elastic rope enters the locking groove 13 through elastic deformation. The locking teeth 14 restrict the movement of the elastic rope along the long side of the locking groove 13, and the anti-detachment part 15 prevents the free end of the elastic rope from leaving the position of the locking groove 13. In this way, the elastic rope is very stable after being locked into the locking groove 13. The length of the elastic rope between the outlet end 112 and the outlet hole 12 is the effective length. When the effective length needs to be adjusted, the free end of the elastic rope is removed from the position of the locking groove 13, and the elastic rope is slidably adjusted in the outlet hole 12. Then, the free end of the elastic rope is locked back into the position of the locking groove 13, and the adjustment is completed.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
