Description

Technical Field

[0001] This application relates to the technical field of jump ropes, and in particular to a jump rope rotor device, a jump rope handle, and a jump rope. Background Technology

[0002] Rope skipping is a sport in which one or more people perform various jumping movements in a swinging rope. It combines playfulness and exercise value, and is a highly efficient full-body exercise that can significantly improve a person's coordination, reaction speed, and cardiorespiratory endurance. At the same time, it has a positive effect on shaping the body and promoting health.

[0003] In related technologies, a jump rope includes a jump rope handle and a rope body. The rope body is fixedly connected to the jump rope handle. The jump rope handle includes a jump rope rotor device and a handle housing. The jump rope rotor device is fixedly connected to the handle housing. The jump rope rotor device has a placement groove for the rope body to pass through. The placement groove can prevent the rope body from detaching after being knotted.

[0004] When people of different heights use the same jump rope, the length of the rope needs to be adjusted. Since the rope is fixed to the jump rope rotor by knots, people need to untie the knots and then adjust the length of the rope. After adjusting the length, the knots need to be tied again to fix it, which makes the process of adjusting the length of the rope cumbersome and time-consuming. Utility Model Content

[0005] To address the cumbersome process of adjusting the length of a jump rope, this application provides a jump rope rotor device, a jump rope handle, and a jump rope.

[0006] This application provides a jump rope rotor device, which adopts the following technical solution: A jump rope rotor device includes a rotor housing with a fixing hole for a rope to pass through and a fixing groove. A button is slidably connected in the fixing groove, and the button has a through hole for the rope to pass through. A spring is provided in the fixing groove to drive the button to move away from the fixing groove. When the button is pressed towards the fixing groove, the fixing hole and the through hole are aligned.

[0007] By adopting the above technical solution, when the rope length needs to be adjusted, the user presses the button towards the fixing groove, aligning the through hole with the fixing hole. At this time, the user can adjust the length of the rope. After adjustment, the user releases the button, and the spring drives the button to move away from the fixing groove. The rope is clamped by the alternating through hole and fixing hole, thus fixing the rope and reducing the possibility of rope movement. Compared with adjusting the rope length by tying a knot, this reduces the user's operation steps and provides greater convenience for adjusting the rope length.

[0008] Optionally, the rotor housing is provided with a bearing, and the rotor housing has a limiting ring groove for the bearing to be inserted. The bearing abuts against the outer surface of the rotor housing and the jump rope handle respectively.

[0009] By adopting the above technical solution, the bearings abut against the outer surface of the rotor housing and the jump rope handle respectively, which reduces the friction between the rotor housing and the jump rope handle. This allows the rotor housing to rotate more smoothly in the jump rope handle, reducing the possibility of wear caused by frequent friction between the rotor housing and the jump rope handle. This protects the rotor housing and the jump rope handle, and further extends the service life of the product.

[0010] Optionally, the bearing is provided with a snap-fit ​​component, and the groove wall of the limiting ring groove is provided with a snap-fit ​​ring groove for inserting the snap-fit ​​component. The snap-fit ​​component is located on the side of the bearing away from the button, and the snap-fit ​​component is used to fix the bearing to the rotor housing.

[0011] By adopting the above technical solution, a snap-fit ​​ring groove is provided on the groove wall of the limiting ring groove for the snap-fit ​​component to be inserted. The operator can insert the snap-fit ​​component into the snap-fit ​​ring groove. Since the snap-fit ​​component is located on the side of the bearing away from the button, the snap-fit ​​component can limit the bearing and reduce the possibility of the bearing dislodging from the limiting ring groove, thereby enhancing the stability between the rotor housing and the bearing and allowing the bearing to be stably located in the limiting ring groove.

[0012] Optionally, the snap-fit ​​component is provided with a stepped block, and the rotor housing is provided with a rotating plane. The stepped block abuts against the rotating plane, and the rotor housing can drive the stepped block to rotate.

[0013] By adopting the above technical solution, when the rotor housing rotates, the stepped block abuts against the rotating plane, enabling the rotor housing to drive the stepped block to rotate synchronously. This allows the rotor housing, the snap-fit ​​component, and the bearing to rotate synchronously, reducing the possibility of frictional damage caused by the relative movement of the snap-fit ​​component and the rotor housing, and further extending the service life of the components.

[0014] Optionally, the button is provided with a locking block that extends into a fixing hole and is used to prevent the button from disengaging from the fixing slot.

[0015] By adopting the above technical solution, the locking block extends into the fixing hole, which can restrict the button from leaving the fixing groove, reduce the possibility of the button leaving the fixing groove, thereby enhancing the overall stability of the device and preventing the button from being thrown out of the fixing groove during the rope swinging process, which would cause damage to the spring.

[0016] Optionally, the card block is provided with a guide slope, and the distance from the guide slope to the button axis gradually decreases along the direction of the button insertion fixing slot. The guide slope is used to guide the button to be inserted into the fixing slot.

[0017] By adopting the above technical solution, the distance from the guide slope to the button axis gradually decreases along the direction of the button insertion into the fixing groove, so that the button can be inserted into the fixing groove more smoothly along the direction of the guide slope, providing greater convenience for users to install the button in the fixing groove.

[0018] Secondly, the jump rope handle provided in this application adopts the following technical solution: A jump rope handle includes the jump rope rotor device and a handle housing. The handle housing includes a first shell and a second shell, and a mounting groove for inserting the rotor housing is formed between the first shell and the second shell. The handle housing is provided with fasteners for fixing the first shell to the second shell, and a limiting groove for inserting a bearing is formed on the groove wall of the mounting groove.

[0019] By adopting the above technical solution, the workers first insert the rotor housing into the mounting groove so that the bearing is located in the limiting groove. Then, the first housing and the second housing are aligned and fastened together. This makes it easier for the workers to install the handle housing and the jump rope rotor device. The mounting groove and the limiting groove limit the rotor housing and the bearing respectively, reducing the possibility of the rotor housing and the bearing moving in the handle housing, thereby enhancing the overall stability of the device.

[0020] Thirdly, the jump rope provided in this application adopts the following technical solution: A jump rope includes a jump rope handle and a rope body. The handle housing is provided in two parts, and the two ends of the rope body are respectively fixedly connected to the two handle housings.

[0021] By adopting the above technical solution, with the two ends of the rope fixedly connected to the two handle housings respectively, the user can adjust the length of the rope by directly pressing the button, which provides convenience for the user to adjust the length of the rope, making the jump rope suitable for users of different heights, thereby improving the applicability of the jump rope.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When adjusting the rope length, the user presses the button closer to the fixing slot, aligning the through hole with the fixing hole. The user can then adjust the rope length. After adjustment, the user releases the button, and the spring drives the button to move away from the fixing slot. The through hole and fixing hole alternately clamp the rope, fixing it in place and reducing the possibility of rope movement. Compared to adjusting the rope length by tying a knot, this reduces the user's steps and provides greater convenience for adjusting the rope length.

[0023] 2. By having bearings abut against the outer surface of the rotor housing and the jump rope handle respectively, the bearings can reduce the friction between the rotor housing and the jump rope handle, thereby allowing the rotor housing to rotate more smoothly in the jump rope handle. This reduces the possibility of wear caused by frequent friction between the rotor housing and the jump rope handle, thus protecting the rotor housing and the jump rope handle and further extending the service life of the product.

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This embodiment discloses a jump rope. (Refer to...) Figure 1 A jump rope includes a handle 1 and a rope body 11, with the rope body 11 fixedly connected to the handle 1. The handle 1 includes a jump rope rotor device 2 and a handle housing 12. Two handle housings 12 are provided, with each end of the rope body 11 fixedly connected to a corresponding handle housing 12. Friction stripes are provided on the outer surface of the handle housing 12 to increase friction and reduce the possibility of the handle housing 12 slipping from the user's hand.

[0028] Reference Figure 2 The handle housing 12 includes a first housing 121 and a second housing 122. A mounting groove 123 for inserting the jump rope rotor device 2 is formed between the first housing 121 and the second housing 122. A first snap-fit ​​structure 124 is fixedly connected to the first housing 121, and a second snap-fit ​​structure 125 is fixedly connected to the second housing 122. The first snap-fit ​​structure 124 and the second snap-fit ​​structure 125 are snap-fitted together to achieve alignment of the first housing 121 and the second housing 122.

[0029] Reference Figure 2 The handle housing 12 is provided with fasteners 126 for fixing the first housing 121 and the second housing 122. The fasteners 126 are bolts. After the workers align the first housing 121 and the second housing 122, they connect them by bolting the fasteners 126 to realize the installation of the handle housing 12.

[0030] Reference Figure 1 and Figure 3 The jump rope rotor device 2 includes a rotor housing 21. A fixing hole 211 is formed on the outer surface of the rotor housing 21 for the rope 11 to pass through. The fixing hole 211 extends through both opposite sides of the rotor housing 21. A fixing groove 212 is formed on the end face of the rotor housing 21 along its length. A button 22 is slidably connected within the fixing groove 212. An opening inclined surface 213 is formed on the surface of the rotor housing 21 where the fixing groove 212 is located. The distance from the opening inclined surface 213 to the axis of the button 22 gradually decreases along the direction in which the button 22 is inserted into the fixing groove 212. The opening inclined surface 213 guides the button 22 into the fixing groove 212.

[0031] Reference Figure 3 A through hole 221 for the rope 11 to pass through is provided on the outer surface of the button 22, and the through hole 221 extends along the diameter of the button 22. A spring 223 is fixedly connected to the bottom wall of the fixing groove 212, and the end of the spring 223 away from the bottom wall of the fixing groove 212 is fixedly connected to the button 22. The spring 223 is used to drive the button 22 to move away from the bottom wall of the fixing groove 212. A positioning block 222 is fixedly connected to the button 22 near the bottom wall of the fixing groove 212, and the spring 223 is sleeved on the outer surface of the positioning block 222.

[0032] Reference Figure 1 and Figure 3 When button 22 is pressed towards the bottom wall of the fixing groove 212, the fixing hole 211 and the through hole 221 are aligned, allowing the user to adjust the length of the rope 11. After adjusting the length of the rope 11, the user releases button 22, and spring 223 drives button 22 to move away from the bottom wall of the fixing groove 212, causing the fixing hole 211 and the through hole 221 to interlock. Through the cooperation of the fixing hole 211, the through hole 221, and the spring 223, the rope 11 can be clamped to fix its length.

[0033] Reference Figure 1 and Figure 3 A limiting ring groove 214 is formed on the outer surface of the rotor housing 21. A bearing 23 is sleeved in the limiting ring groove 214. The bearing 23 abuts against the outer surface of the rotor housing 21 and the jump rope handle 1 respectively. The bearing 23 is used to reduce the friction between the rotor housing 21 and the jump rope handle 1.

[0034] Reference Figure 3 The retaining ring groove 214 has a snap-fit ​​ring groove 215 on its groove wall. A snap-fit ​​member 24, made of plastic and shaped like an open annular ring, is fitted inside the snap-fit ​​ring groove 215. The snap-fit ​​member 24 is located on the side of the bearing 23 away from the button 22, and is positioned along the movement path of the bearing 23 as it disengages from the retaining ring groove 214. By inserting the snap-fit ​​member 24 into the snap-fit ​​ring groove 215, the bearing 23 is effectively confined within the retaining ring groove 214.

[0035] Reference Figure 4 A step block 241 is fixedly connected to the surface of the snap-fit ​​part 24 away from the opening. A rotating plane 216 that abuts against the step block 241 is provided on the end face of the rotor housing 21 away from the button 22. The rotor housing 21 can drive the step block 241 to rotate synchronously.

[0036] Reference Figure 4 Each of the outer surfaces opposite to the button 22 has a locking block 224 fixedly connected to it. The locking block 224 extends into the fixing hole 211 and can prevent the button 22 from detaching from the fixing groove 212. A guide slope 225 is formed on the surface of the locking block 224 away from the button 22. The distance from the guide slope 225 to the axis of the button 22 gradually decreases along the direction in which the button 22 is inserted into the fixing groove 212, so that the button 22 can be inserted into the fixing groove 212 more smoothly along the inclined direction of the guide slope 225.

[0037] Reference Figure 1 and Figure 5The mounting groove 123 has a limiting groove 127 for the bearing 23 to be inserted into. Multiple reinforcing ribs 128 are fixedly connected to the groove wall of the limiting groove 127. The reinforcing ribs 128 are used to reinforce the internal structure of the shell. The gaps between the multiple reinforcing ribs 128 can reduce the weight of the jump rope, so that the user can swing the rope 11.

[0038] Reference Figure 2 The handle housing 12 is equipped with a counting device 3, which rotates with the rotor housing 21 to realize the function of counting jump ropes.

[0039] The implementation principle of a jump rope according to an embodiment of this application is as follows: the user presses the button 22 into the fixing groove 212, so that the through hole 221 is aligned with the fixing hole 211, thereby unlocking the rope 11. The user can adjust the length of the rope 11, and then release the button 22. The rope 11 is clamped by the alternation of the fixing hole 211 and the through hole 221.
