Description

Technical Field

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

[0002] Jumping rope is a popular sport that requires little space and provides excellent exercise. However, because everyone's height is different, the length of the jump rope needs to be adjusted according to height. In existing technology, the length of the jump rope is usually adjusted by the handles. For example, the existing patent CN213313123U discloses an adjustable length fancy jump rope, which includes two handles and a rope connecting the two handles. One handle has a cavity inside, and a rope-winding shaft is rotatably connected inside the cavity. One end of the rope is fixed to the rope-winding shaft and the rope is wound around the rope-winding shaft multiple times. The length of the rope connecting the two handles is adjusted by adjusting the number of times the rope is wound around the rope-winding shaft. However, in use, the rope wound on the rope-winding shaft cannot be evenly distributed. The jump rope is easy to tangle and pile up at the end of the rope-winding shaft near the other handle, causing the rope-winding shaft to get stuck in the cavity, making it inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a jump rope to solve the problems existing in the prior art and make the jump rope more convenient to use.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a jump rope, including a rope body and two handles. The two ends of the rope body are respectively connected to the two handles. At least one handle is an adjusting handle. The adjusting handle includes a handle body, a rope winding shaft, and a vernier. The handle body has a cavity, and the rope winding shaft rotates around its axis within the cavity. The vernier is threaded onto the rope winding shaft and slidably connected to the cavity along a direction parallel to the axis of the rope winding shaft. The vernier has a first rope-passing hole. The handle body has a rope inlet, which communicates with the cavity. The rope body can enter the cavity through the rope inlet, then pass through the first rope-passing hole and be fixedly connected to a first position on the adjusting handle, located between the first rope-passing hole and the first... The rope between the positions forms a winding segment, which can be wound around the winding shaft at the end of the first rope hole away from the rope inlet. Rotating the winding shaft in a first direction can bring the vernier closer to the rope inlet and increase the number of turns of the winding segment on the winding shaft to reduce the length of the rope between the two handles. Rotating the winding shaft in a second direction can move the vernier away from the rope inlet and reduce the number of turns of the winding segment on the winding shaft to increase the length of the rope between the two handles. The first direction and the second direction are opposite. A limiting device is connected to the handle body, which can limit the rotation of the winding shaft or release the rotation of the winding shaft.

[0006] In some embodiments, the handle body includes a grip portion and an adjustment portion. The grip portion has a cavity inside. The adjustment portion is fixedly connected to the winding shaft and is rotatably connected to the grip portion about the axis of the winding shaft.

[0007] In some embodiments, the axis of the gripping part coincides with the axis of the winding shaft. The adjusting part includes a connecting cylinder and a fixing plate. The connecting cylinder is rotatably connected to the outer wall of the gripping part about the axis of the gripping part. The fixing plate is fixedly connected inside the connecting cylinder. The winding shaft is fixedly connected to the fixing plate. The fixing plate is provided with protruding teeth around the circumference of the winding shaft. When the limiting device is engaged between two adjacent protruding teeth, it can restrict the rotation of the winding shaft. When the limiting device is disengaged from between two adjacent protruding teeth, it can release the rotation of the winding shaft.

[0008] In some embodiments, two limiting blocks are fixedly connected to one end of the fixed plate away from the winding shaft, and the first position is formed between the two limiting blocks. A second rope-passing hole is provided on the fixed plate, and the end of the rope wound on the winding shaft can pass through the second rope-passing hole and be interference-fitted with the two limiting blocks and limited between the two limiting blocks.

[0009] In some embodiments, a limiting groove is formed at one end of the gripping part near the adjusting part. The limiting device is movably connected to the limiting groove along the axial direction of the gripping part. The limiting device includes an elastic element, a locking block, and a pressing block. The projected area of ​​the locking block is larger than the groove opening area of ​​the limiting groove. The elastic element is fixedly connected to one end of the locking block. The pressing block is fixedly connected to the side wall of the locking block and protrudes from the groove opening of the limiting groove. Under the elastic force of the elastic element, the locking block can lock between two adjacent protrusions. Moving the pressing block away from the fixed plate can cause the locking block to compress the elastic element and disengage the locking block from between the two adjacent protrusions.

[0010] In some embodiments, the handle further includes a connector, and the end of the grip portion away from the adjustment portion is provided with a support hole and a third rope hole. The rope winding shaft passes through the support hole and can rotate within the support hole. The connector is connected to the grip portion and can cover the support hole and the third rope hole. The rope inlet is opened on the connector, and the rope can pass through the rope inlet and the third rope hole in sequence to enter the cavity.

[0011] In some embodiments, the inner wall of the gripping part is fixedly connected to a slide rail extending along the axis of the gripping part, and the vernier is provided with a slot, which can be engaged with the slide rail and slide along the slide rail.

[0012] In some embodiments, the outer wall of the connecting cylinder is provided with stripes protruding from the outer wall of the connecting cylinder.

[0013] In some embodiments, the connector is threadedly connected to the gripping portion.

[0014] In some embodiments, a bearing is fixedly connected to the inner wall of the rope inlet 19, and the rope can pass through the channel in the bearing and the third rope hole in sequence to enter the cavity.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] This utility model provides a jump rope. By incorporating a rope-winding shaft and a vernier within the adjusting handle, a winding segment is formed between the rope hole and the rope body fixedly connected to the adjusting handle. The rope body can wind around the rope-winding shaft at the end of the vernier furthest from the rope inlet. The vernier limits the winding segment, ensuring it is distributed only on the end of the rope-winding shaft furthest from the rope inlet. Rotating the rope-winding shaft adjusts the distance of the vernier relative to the rope inlet, thus adjusting the length that can be wound on the rope-winding shaft. This allows the winding segment to be evenly wound around or released from the rope-winding shaft as the vernier moves, preventing the rope from completely winding around the end of the rope-winding shaft near the rope inlet, which could cause the shaft to jam. This makes it more convenient to use. Furthermore, the limiting device restricts or releases the rotation of the rope-winding shaft, allowing the adjusting handle to adjust the rope length between the two handles and fix the adjusted rope length between the two handles, further enhancing usability.

Detailed Implementation

[0025] 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.

[0026] The purpose of this invention is to provide a jump rope to solve the problems existing in the prior art and make the jump rope more convenient to use.

[0027] 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.

[0028] This utility model provides a jump rope, such as Figures 1-6 As shown, the device includes a rope body 2 and two handles 1. The two ends of the rope body 2 are respectively connected to the two handles 1. At least one handle 1 is an adjusting handle. The adjusting handle includes a handle body, a rope winding shaft 9, and a vernier 11. The handle body has a cavity, and the rope winding shaft 9 rotates within the cavity around its axis. The vernier 11 is threaded onto the rope winding shaft 9 and slides within the cavity in a direction parallel to the axis of the rope winding shaft 9. The vernier 11 has a first rope-passing hole 10. The handle body has a rope inlet 19, which communicates with the cavity. The rope body 2 can enter the cavity through the rope inlet 19, then pass through the first rope-passing hole 10 and be fixedly connected to the adjusting handle at a first position, located between the first rope-passing hole 10 and the second... The rope 2 between the two positions forms a winding section, which can be wound around the winding shaft 9 at the end of the first rope hole 10 away from the rope inlet 19. Rotating the winding shaft 9 in the first direction can bring the vernier 11 closer to the rope inlet 19 and increase the number of turns of the winding section on the winding shaft 9 to reduce the length of the rope 2 between the two handles 1. Rotating the winding shaft 9 in the second direction can bring the vernier 11 away from the rope inlet 19 and reduce the number of turns of the winding section on the winding shaft 9 to increase the length of the rope 2 between the two handles 1. The first direction and the second direction are opposite. A limiting device 6 is connected to the handle body. The limiting device 6 can restrict the rotation of the winding shaft 9 or release the rotation of the winding shaft 9.

[0029] By setting a winding shaft 9 and a vernier 11 inside the adjusting handle, the first rope hole 10 and the rope 2 fixedly connected between the adjusting handles form a winding section. The rope 2 can be wound around the winding shaft 9 at the end of the vernier 11 away from the rope inlet 19. The vernier 11 limits the winding section, so that the winding section can only be distributed on the winding shaft 9 at the end of the vernier 11 away from the rope inlet 19. Rotating the winding shaft 9 adjusts the distance of the vernier 11 relative to the rope inlet 19, which can adjust the length that can be wound on the winding shaft 9. This allows the winding section to be evenly wound on the winding shaft 9 or released from the winding shaft 9 as the vernier 11 moves, avoiding the rope 2 being completely wound around the end of the winding shaft 9 near the rope inlet 19, which would cause the winding shaft 9 to jam. This makes it more convenient to use. In addition, the limiting device 6 can limit or release the rotation of the winding shaft 9 so that the adjusting handle can adjust the length of the rope 2 between the two handles 1, and can fix the length of the rope 2 between the two handles 1 after adjustment, making it more convenient to use.

[0030] In use, when it is necessary to reduce the length of the rope 2 between the two handles 1, the winding shaft 9 is released to rotate via the limiting device 6. Rotating the winding shaft 9 in the first direction causes the vernier 11 to move closer to the rope inlet 19, which increases the number of turns of the winding section on the winding shaft 9 to reduce the length of the rope 2 between the two handles 1. After adjusting to the preset length, the winding shaft 9 is restricted from rotating via the limiting device 6 to fix the adjusted length of the rope 2 between the two handles 1. When it is necessary to increase the length of the rope 2 between the two handles 1, the winding shaft 9 is released to rotate via the limiting device 6. The rope 2 between the two handles 1 is pulled by hand in the direction away from the adjusting handle, causing the winding shaft 9 to rotate in the second direction to move the vernier 11 away from the rope inlet 19. This reduces the number of turns of the winding section on the winding shaft 9 to increase the length of the rope 2 between the two handles 1. After adjusting to the preset length, the winding shaft 9 is restricted from rotating via the limiting device 6 to fix the adjusted length of the rope 2 between the two handles 1.

[0031] In another embodiment of this invention, the handle body includes a gripping part 3 and an adjusting part. The gripping part 3 has an internal cavity. The adjusting part is fixedly connected to the rope-winding shaft 9 and is rotatably connected to the gripping part 3 around the axis of the rope-winding shaft 9. The inner wall of the adjusting part is engaged with the outer wall of the gripping part 3 and is rotatable around the axis of the gripping part 3. The adjusting part is fixedly connected to the rope-winding shaft 9; rotating the adjusting part drives the rope-winding shaft 9 to rotate around its axis, thereby adjusting the length of the rope 2 between the two handles 1, making it more convenient to use.

[0032] In another embodiment of this invention, the axis of the gripping part 3 coincides with the axis of the winding shaft 9. The adjusting part includes a connecting cylinder 5 and a fixing plate 8. The connecting cylinder 5 is rotatably connected to the outer wall of the gripping part 3 about the axis of the gripping part 3. The fixing plate 8 is fixedly connected inside the connecting cylinder 5. The winding shaft 9 is fixedly connected to the fixing plate 8. The fixing plate 8 has protruding teeth 15 arranged circumferentially around the winding shaft 9. When the limiting device 6 is engaged between two adjacent protruding teeth 15, it can restrict the rotation of the winding shaft 9. When the limiting device 6 is disengaged from between two adjacent protruding teeth 15, it can release the rotation of the winding shaft 9. Rotating the connecting cylinder 5 can drive the winding shaft 9 to rotate, thereby adjusting the length of the rope 2 between the two handles 1, making it more convenient to use.

[0033] It should be noted that the adjustment part of the jump rope provided by this utility model is not limited to the structure in the above embodiments. The adjustment part can also adopt a screw, handle or other structure that can drive the rope shaft 9 to rotate. The end of the screw or handle is fixedly connected to the rope shaft 9. The screw is threadedly connected to the holding part 3. The cross-sectional shape of the adjustment part can be, but is not limited to, circular, square or other shapes, as long as operating the adjustment part can drive the rope shaft 9 to rotate.

[0034] In another embodiment of this invention, two limiting blocks 7 are fixedly connected to one end of the fixing plate 8 away from the winding shaft 9, forming a first position between the two limiting blocks 7. A second rope-passing hole 14 is provided on the fixing plate 8, allowing the end of the rope 2 wound on the winding shaft 9 to pass through the second rope-passing hole 14 and be interference-fitted between the two limiting blocks 7. By interfering with the two limiting blocks 7, the rope 2 can be fixed, preventing it from coming off the adjusting handle. This also facilitates fixing and disassembly, making it easy to replace the rope 2 and providing convenient use.

[0035] In another embodiment of this example, a limiting groove is provided at one end of the gripping part 3 near the adjusting part. The limiting device 6 is movably connected to the limiting groove along the axial direction of the gripping part 3. The limiting device 6 includes an elastic element 12, a locking block 17, and a pressing block 16. The projected area of ​​the locking block 17 is larger than the groove area of ​​the limiting groove. The elastic element 12 is fixedly connected to one end of the locking block 17. The pressing block 16 is fixedly connected to the side wall of the locking block 17 and protrudes from the groove of the limiting groove. Under the elastic force of the elastic element 12, the locking block 17 can be locked between two adjacent protrusions 15. Moving the pressing block 16 away from the fixing plate 8 can drive the locking block 17 to compress the elastic element 12 and disengage the locking block 17 from between the two adjacent protrusions 15. By setting up a pressing block 16, pressing and pushing the pressing block 16 to move away from the fixed plate 8 can drive the locking block 17 to move, thereby compressing the elastic element 12 between the inner wall of the limiting groove and the locking block 17. The locking block 17 disengages from the two adjacent protrusions 15 to release the winding shaft 9. When the pressing block 16 is released, the elastic force of the elastic element 12 is released. Under the action of the elastic force of the elastic element 12, the locking block 17 moves towards the fixed plate 8 and locks between the two adjacent protrusions 15 to limit the winding shaft 9. The structure is simple and easy to use.

[0036] In another embodiment of this invention, the handle 1 further includes a connector 4. The end of the gripping part 3 away from the adjustment part is provided with a support hole 20 and a third rope hole 22. The rope shaft 9 passes through the support hole 20 and can rotate within the support hole 20. The connector 4 is connected to the gripping part 3 and can cover the support hole 20 and the third rope hole 22. The rope inlet 19 is opened on the connector 4. The rope body 2 can pass through the rope inlet 19 and the third rope hole 22 in sequence and enter the cavity. The connector 4 has an internal accommodating space. The rope-winding shaft 9 inside the support hole 20 extends into the accommodating space of the connector 4. A limiting buckle 18 is provided on the rope-winding shaft 9 to axially limit its movement. The projected area of ​​the limiting buckle 18 is larger than the area of ​​the support hole 20. The limiting buckle 18 is engaged with the limiting groove on the end of the rope-winding shaft 9 extending from the support hole 20, and is pressed tightly against the side wall of the grip 3 near the rope inlet 19. This axially limits the rope-winding shaft 9, preventing it from moving during use and thus ensuring the rope length between the two handles 1 is maintained, making it more convenient to use. For details on the shape of the limiting buckle 18, see [link to details]. Figure 6 The limiting buckle 18 is a ring with an opening.

[0037] In another embodiment of this invention, a slide rail 13 extending along the axis of the grip 3 is fixedly connected to the inner wall of the grip 3. A slot 21 is provided on the vernier 11, which can engage with the slide rail 13 and slide along the slide rail 13. The slide rail 13 can limit the vernier 11, preventing it from rotating with the winding shaft 9, but instead allowing it to slide along the slide rail 13. This allows adjustment of the distance between the vernier 11 and the fixed plate 8, so that the winding section can be evenly wound onto or released from the winding shaft 9 as the vernier 11 moves. This avoids the rope 2 from being completely wound around the end of the winding shaft 9 near the rope inlet 19, causing the winding shaft 9 to jam, making it more convenient to use.

[0038] In another embodiment of this invention, the outer wall of the connecting cylinder 5 is provided with stripes protruding from the outer wall of the connecting cylinder 5. Protruding stripes on the outer wall of the connecting cylinder 5 increase the friction of the outer wall, making it easier to rotate the connecting cylinder 5 and adjust the length of the rope 2 between the two handles 1.

[0039] In another embodiment of this invention, the connector 4 is threadedly connected to the gripping part 3. This facilitates easy disassembly and assembly for adjustment, making maintenance more convenient.

[0040] It should be noted that the connection method between the connector 4 and the grip part 3 of the jump rope provided by this utility model is not limited to the structure in the above embodiment. It can also adopt a structure such as snap-fit ​​that allows the connector 4 and the grip part 3 to be detachably connected.

[0041] In another embodiment of this invention, the elastic element 12 is a spring. Springs have excellent elastic properties, can deform when subjected to external force, and have significant elastic restoring force, effectively absorbing and releasing energy. Compressing or releasing the spring allows the locking block 17 to disengage from or engage with adjacent protrusions 15, making operation simple and convenient.

[0042] It should be noted that the elastic element 12 of the jump rope provided by this utility model is not limited to the structure in the above embodiments, and can also be a structure with elastic properties such as rubber.

[0043] In another embodiment of this invention, a bearing 23 is fixedly connected to the inner wall of the rope inlet 19. The rope 2 can pass through the channel inside the bearing 23 and the third rope hole 22 in sequence to enter the cavity. The inner wall of the rope inlet 19 can form a sleeve, and the bearing 23 is threadedly connected to the inner wall of the rope inlet 19. The bearing 23 enables the rope 2 inside the channel of the bearing 23 to rotate more smoothly during use, reducing the resistance to the rotation of the rope 2.

[0044] It should be noted that the connection method between the bearing 23 and the rope inlet 19 of the jump rope provided by this utility model is not limited to the structure in the above embodiment. It can also adopt a snap-fit ​​or other method that can fix the bearing 23 and the rope inlet 19.

[0045] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​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. In summary, the content of this specification should not be construed as a limitation of this utility model.
