[0028] In the following, a kind of rope skipping handle and rope skipping provided by the utility model will be described in more detail in combination with specific embodiments and its related drawings.
[0029] Please refer to Figures 1-3 , Figure 1 is the structure diagram of the rope skipping provided by the utility model,Figure 2 is an explosion view of the jump rope provided by the utility model, Figure 3 is a sectional view of the jump rope provided by the utility model. The utility model provides a jump rope handle which is mainly composed of an upper cover 10, a handle shell 20, a bearing 30 and a clamping piece 40. Among them, the upper cover 10 is provided with a through hole 11, and the through hole 11 is used for the passing of a jump rope body 60. The upper cover 10 is detachably connected with the handle shell 20, so that users can easily assemble or disassemble it according to needs. The upper cover 10 and the handle shell 20 are internally mutually penetrated, and jointly form a cavity 21, which is used for placing the bearing 30, the clamping piece 40 and the jump rope body 60. The clamping piece 40 is used for fixing the jump rope body 60, and the clamping piece 40 comprises a clamping column 41, the side surface of the clamping column 41 is provided with an opening, the opening is provided with a clamping claw 411, and the clamping claw 411 is elastically connected with the clamping column 41 through welding or integral molding. The clamping claw 411 extends downward from the side opening top surface of the clamping column 41, that is, the top end of the clamping claw 411 is connected with the side opening top surface, and the lower end of the clamping claw 411 is a free end not connected with the clamping column 41. When assembling the jump rope, the user passes the jump rope body 60 through the clamping column 41, and then pushes the clamping piece 40 with the jump rope body 60 into the bearing 30. With the deepening of the clamping piece 40, the clamping claw 411 is subjected to the radial extrusion force applied by the inner wall of the bearing 30, so that the clamping claw 411 is forced to shrink inward, thereby firmly locking the jump rope body 60. When adjusting the length of the jump rope body 60, the user only needs to pull out the clamping piece 40, and then pushes the clamping piece 40 into the bearing 30 again after adjusting the clamping piece 40 to the appropriate position of the jump rope body 60, so that the whole process simplifies the installation and adjustment of the jump rope body 60.
[0030] Please continue to refer to Figure 4 , Figure 4 is a structural schematic view of the bearing 30 in the utility model. The bearing 30 provided by the utility model comprises a bearing inner ring 31 and a bearing outer ring 32, the axial length of the bearing inner ring 31 is greater than the axial length of the bearing outer ring 32, and the bearing capacity and stability of the bearing 30 are improved. At the same time, the axial length of the bearing inner ring 31 is greater than that of the clamping column 41, so that the clamping claw 411 can be completely placed in the bearing inner ring 31, the clamping piece 40 and the jump rope body 60 can be fixed in the bearing inner ring 31, and the three are integrated and can rotate freely in the bearing outer ring 32, so that knotting is not easy. In the length direction of the jump rope handle, the bearing outer ring 32 abuts against the upper cover 10 and the handle shell 20 respectively, which not only ensures the accurate positioning of the bearing 30 in the jump rope handle, but also effectively prevents the axial movement of the bearing 30 during the jump rope process, thereby ensuring the stability of the jump rope handle. The bearing inner ring 31 can extend into the through hole 11 of the upper cover 10, and this design avoids the friction caused by the contact between the jump rope body 60 and the upper cover 10, and reduces the risk of damage to the jump rope body 60.
[0031] Preferably, the clamping member 40 is made of elastic material, which can be elastically deformed when extruded by external force and quickly return to the original state when the external force disappears. The selection of the elastic material not only improves the durability and service life of the clamping member 40, but also enables the clamping member 40 to lock the rope 60 more tightly, preventing the rope 60 from accidentally falling off during use. At the same time, by adjusting the size of the clamping member 40, the rope handle can better adapt to ropes 60 of different diameters.
[0032] Please continue to refer to Figure 5 and Figure 6 , Figure 5 is a structural schematic view of the clamping member 40 in the utility model, Figure 6 is Figure 5 a cross-sectional view of the clamping member 40. The clamping member 40 has at least one clamping jaw 411. Preferably, the clamping member 40 has a pair of symmetrically arranged clamping jaws 411. The clamping jaw 411 has an outer convex structure 4111 and an inner convex structure 4112. In the actual use of the rope handle, when the clamping member 40 is pushed into the bearing inner ring 31, the outer convex structure 4111 first contacts the bearing inner ring 31. Due to the extrusion of the bearing inner ring 31 on the outer convex structure 4111 of the clamping jaw 411, the clamping jaw 411 will be deformed, which further causes the inner convex structure 4112 to be pulled and thus shrink inward to lock the rope 60. Preferably, the inner convex structure 4112 is designed to be inclined to enhance the friction between the rope and the clamping jaw 411. The outer convex structure 4111 and the inner convex structure 4112 can adopt various shapes, such as a circular protrusion.
[0033] Preferably, the outer convex structure 4111 and the inner convex structure 4112 each have an inclined surface. The cross-sectional shape of the clamping jaw 411 is isosceles trapezoidal. Specifically, the inclined surface of the outer convex structure 4111 is designed to provide a guiding effect when the clamping member 40 and the rope 60 are pushed into the bearing inner ring 31. The inclined surface design makes the pushing process smoother, reducing the risk of damage to the clamping member 40. The inclined surface of the inner convex structure 4112 is designed for the rope 60. When the clamping jaw 411 is extruded by the bearing inner ring 31 and shrinks inward, this inclined surface can guide the rope 60 to smoothly enter the locking range of the clamping jaw 411. This design not only improves the locking efficiency, but also ensures that the rope 60 can be securely fixed in the clamping jaw 411, avoiding the phenomenon of loosening or falling off that may occur during the rope.
[0034] Further, the clamping member 40 further comprises a clamping seat 42, the outer diameter of the clamping seat 42 is larger than the outer diameter of the clamping column 41, and the clamping seat 42 can abut against the bearing inner ring 31 to limit the insertion depth of the clamping column 41 when the clamping member 40 is inserted into the bearing inner ring 31. Specifically, when the clamping member 40 is inserted into the bearing inner ring 31, the clamping column 41 will first contact the bearing inner ring 31. With the application of external force, the clamping column 41 continuously penetrates, and since the outer diameter of the clamping seat 42 is larger than the outer diameter of the clamping column 41 and the bearing inner ring 31, it can effectively abut against the bearing inner ring 31, thereby playing a role in limiting the insertion depth of the clamping column 41, and further avoiding the situation that the clamping member 40 cannot be taken out from the bearing inner ring 31 due to over-insertion.
[0035] Please refer back to Figure 3 and refer to Figure 7 , Figure 3 is a sectional view of the jump rope provided by the utility model, Figure 7 is Figure 3 Figure 7 the local enlarged schematic view of the A area. The handle shell cavity 21 is further provided with an annular retaining ring 22, which forms an effective limiting action on the clamping member 40. Specifically, when the clamping member 40 is loosened in the bearing inner ring 31, the annular retaining ring 22 will prevent the clamping member 40 from further moving out of the bearing inner ring 31, thereby ensuring that the clamping member 40 can always be clamped and fixed inside the bearing inner ring 31, preventing the axial movement of the jump rope body 60 due to the movement or loosening of the clamping member 40.
[0036] Preferably, the distance between the annular retaining ring 22 and the clamping member 40 is 1-2mm.
[0037] Further, the handle shell 20 is externally provided with an anti-skid sleeve 50 for increasing the comfort of holding the jump rope handle with hands, and the anti-skid sleeve 50 is not easy to fall off.
[0038] The utility model further provides a jump rope, which adopts the jump rope handle assembled and connected with the bearing 30 through the clamping member 40 in the above example.
