[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This utility model designs the rope threading part and the clamping part as a threaded connection structure, which is convenient for assembly. When fixing jump ropes of different sizes, the displacement of the clamping part is measured in units of wire, pre-tightening one wire at a time, resulting in high clamping accuracy and good fastening effect. By setting the first clamping protrusion, when the clamping part is connected to the rope threading part, the first clamping protrusion acts like claw teeth, firmly clamping the rope and preventing it from loosening.

[0027] 2. The present invention designs the first pressing protrusion as a hemispherical protrusion structure around the bottom edge of the pressing part, which can reduce the scratches on the outer surface of the rope when tightening and pre-pressing.

[0028] 3. This utility model features protrusions at the inlet and outlet of the rope hole. These protrusions, used in conjunction with the clamping part, support the jump rope and prevent it from dangling at the clamping point. This further enhances the tightness and locking effect of the jump rope, providing excellent anti-loosening performance. The upper surface of the protrusion has a row of upward-protruding wavy surfaces, which are used for locking the jump rope after tightening, preventing it from loosening during high-speed jumping. The angled teeth in this utility model increase friction, allowing for better tightening with fingers when pressing, preventing bearing rotation, and thus preventing the rope threading part from rotating relative to the handle body.

[0029] 4. In this utility model, the rope threading part is connected to the handle body through a bearing, which can reduce the rotational resistance of the rope threading part. The stop is located outside the handle body and is not connected to the handle body. Therefore, it will not affect the rotation of the rope threading part relative to the handle during use.

[0030] 5. This utility model features a cross-shaped groove at the top of the clamping part, facilitating screwdriver tightening and making tightening easier with less effort. The outer periphery of the clamping part has a symmetrical planar structure, while the side planar structure is used for tightening with an open-end wrench. Depending on usage requirements, a set of anti-slip surfaces is also symmetrically designed on the outer periphery of the clamping part. The anti-slip surface with vertical grooves increases friction, preventing slippage and reducing effort when tightening by hand.

[0031] 6. This utility model features a dual-bearing design, resulting in a faster and more stable rotation speed during high-speed rope skipping.

[0032] 7. The structural design of this utility model, which features an alternating anti-slip diagonal pattern in the thumb positioning groove and several hemispherical protrusions in the index finger positioning groove, facilitates quick positioning during use and also provides user comfort.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] like Figure 1-5 As shown, a jump rope handle includes a handle body 100, a rope threading part 200 rotatably connected to the handle body, and a clamping part 300 connected to the rope threading part 200 to fix a jump rope 400 passing through a rope hole 201 of the rope threading part 200.

[0043] In one specific embodiment, the rope threading part 200 coincides with the central axis of the handle body 100. The rope threading part 200 consists of a connector 201, a stop 202, and a rotating shaft 203 from top to bottom. The central axes of the connector 201, the stop 202, and the rotating shaft 203 coincide. The connector 201 and the rotating shaft 203 are located at both ends of the stop 202, and the connector 201, the stop 202, and the rotating shaft 203 are an integral structure.

[0044] In one specific embodiment, the pivot 203 extends into the handle body 100 and is connected to the bearing 500 installed inside the handle body 100.

[0045] The outer diameter of the end of the handle body 100 near the stop 202 is smaller than the outer diameter of the stop 202. The stop 202 is located outside the handle body 100. The outer circumference of the end face of the stop 202 away from the handle body is provided with inclined teeth 2022.

[0046] Specifically, the end of the stop 202 near the handle body 100 is a cylindrical structure, and the end away from the handle body is a truncated cone structure, with a ring of tapered teeth 2022 on the outer circumference of the cone. The tapered teeth 2022 can increase friction, and when tightening, pressing with a finger can better apply force to loosen or loosen the screw, preventing the bearing 500 from rotating, and thus preventing the rope threading part 200 from rotating relative to the handle body 100.

[0047] The connector 201 is located on the upper surface of the truncated cone. The connector 201 is a cylindrical structure with external threads, and a rope passage hole 2011 is formed on the connector 201 along its radial direction. In this embodiment, the diameter of the rope passage hole 2011 is not limited, but it is preferably between 2.5mm and 9.5mm to suit different rope skipping scenarios.

[0048] The clamping part 300 has a bottom column and an upper sphere structure, with the bottom column and upper sphere being an integral structure. A threaded hole with an internal thread is opened along the axial direction of the bottom column to match the external thread on the connector 201. The clamping part 300 is threadedly connected to the connector 201. When the clamping part 300 is screwed downward, it clamps and locks the jump rope 400 passing through the rope hole 2011.

[0049] In one specific embodiment, the bottom surface of the bottom column is provided with a first pressing protrusion 301. Specifically, the first pressing protrusion 301 is provided at the bottom surface of the bottom column between the threaded hole and the outer wall of the bottom column. The first pressing protrusion 301 is a ring of convex spherical structure formed by several hemispherical protrusions evenly distributed along the circumference of the internal threaded hole.

[0050] The threaded connection between the clamping part 300 and the connector 201 facilitates assembly. During tightening, the clamping part 300 displaces in micrometers, pre-tightening one wire at a time, enabling quick and easy fixing of jump ropes of different sizes with high clamping precision and excellent fastening effect. In use, compared to flat clamping, the design of the first clamping protrusion 301 acts like claws, firmly clamping the rope and preventing it from loosening.

[0051] Each protrusion unit of the first clamping protrusion 301 has a hemispherical protrusion structure. When tightening and pre-pressing, the hemispherical protrusion structure design can reduce the scratches on the outer surface of the rope without affecting the clamping effect.

[0052] In one specific embodiment, the rope threading part 200 further includes bosses 2021 symmetrically arranged at both ends of the rope hole 2011. Preferably, the bosses 2021 are located on the upper surface of the truncated cone and are integral with the truncated cone. The upper surface of the bosses 2021 is a row of upward-protruding wavy surfaces, and the surface height of the bosses 2021 is flush with the lower edge of the rope hole 2011.

[0053] The boss 2021 works in conjunction with the first clamping protrusion 301. The boss 2021 supports the jump rope and prevents the jump rope 400 from dangling at the clamping point, further improving the clamping and locking effect of the jump rope 400 by the clamping part 300, and providing good anti-loosening effect. The upper surface of the boss 2021 has a row of upward-protruding wavy surfaces, which are used for locking after the jump rope is tightened, so that it will not loosen when jumping at high speed.

[0054] The top of the upper sphere of the pressing part 300 has a longitudinal groove and a transverse groove with a cross-shaped structure along its radial direction; the two symmetrical surfaces of the outer periphery of the pressing part 300 relative to the longitudinal groove are smooth planar structures 302; the two symmetrical surfaces of the outer periphery of the pressing part 300 relative to the transverse groove are anti-slip surfaces 303 with vertical grooves.

[0055] The handle body 100 has a bearing 500 inside. There are two sets of bearings 500, namely the first bearing and the second bearing. A partition roller 600 is provided between the first bearing and the second bearing. The partition roller 600 is sleeved on the rotating shaft 203. The rotating shaft 203 passes through the first bearing, the partition roller 600 and the second bearing in sequence and is connected to the bearing by the bearing fixing screw.

[0056] In one specific embodiment, the central axes of the first bearing and the second bearing coincide. The first bearing and the second bearing have the same structure, both including an inner bearing ring and an outer bearing ring. Balls are provided between the inner bearing ring and the outer bearing ring. The inner bearing ring is sleeved on the rotating shaft 203 and connected to the rotating shaft 203 by bearing fixing screws, so that the inner bearing ring and the rotating shaft are fixed together as synchronous moving bodies.

[0057] The partition roller 600 is disposed around the rotating shaft 203 and is located between the inner ring of the first bearing and the inner ring of the second bearing and is rigidly connected to both.

[0058] The connection method between the bearing and the shaft in this embodiment can be seen as adopting the existing rotating bearing and shaft connection structure principle.

[0059] The first and second bearings are symmetrically arranged at both ends of the partition roller 600. When jumping rope at high speed, the two bearings move synchronously, resulting in a faster and more stable rotation speed.

[0060] The inner cavity of the handle body 100 is provided with a mounting platform for installing bearings. Specifically, the mounting platform 103 is a step protruding towards its center along the circumference of the inner wall of the handle. The outer ring of the bearing is fixed between two steps and cannot rotate relative to the handle body 100. There are two sets of mounting platforms 103, used for installing the first bearing and the second bearing respectively.

[0061] The handle body 100 includes a first housing and a second housing, which are detachably connected. In one specific embodiment, the first housing and the second housing are fixedly connected by bolts.

[0062] In one specific embodiment, a threaded through hole 102 is provided on the first housing, and a threaded blind hole adapted to the threaded through hole is provided on the second housing. The first housing and the second housing are fixedly connected by bolts.

[0063] In one specific embodiment, there are three sets of threaded through holes and threaded blind holes, which are arranged along the axial direction of the handle body.

[0064] The first housing and / or the second housing are provided with a thumb positioning groove 107 at one end near the rope threading part 200. The thumb positioning groove 107 is provided with an alternating anti-slip fish scale pattern or a number of raised hemispheres.

[0065] In one specific embodiment, the thumb positioning groove 107 at one end of the first housing near the rope threading part 200 is provided with an alternating anti-slip fish scale pattern.

[0066] In one specific embodiment, a plurality of raised hemispheres 108 are provided at the thumb positioning groove 107 at one end of the second housing near the rope threading part 200.

[0067] In one specific embodiment, in order to provide structural strength to the handle body 100, the inner cavities of the first housing and the second housing are provided with a plurality of sets of transverse reinforcing ribs 104 and V-shaped reinforcing ribs 105 at intervals along their length direction, with the V-shaped reinforcing ribs 105 and transverse reinforcing ribs 104 being provided at intervals.

[0068] In one specific embodiment, in order to provide structural strength to the handle body 100, vertical reinforcing ribs 106 are also provided in the inner cavities of the first and second housings along their length direction.

[0069] In this embodiment, the transverse reinforcing ribs 104, V-shaped reinforcing ribs 105, and vertical reinforcing ribs 106 are all located below the mounting platform 103.

[0070] During assembly, the bearing 203 is correctly placed on the mounting platform 103 of the first housing, the shaft 203 of the rope threading part 200 is correctly connected to the bearing 203, the second housing is connected to the first housing, and then the second housing is fixedly connected to the first housing by bolts.

[0071] After passing one end of the jump rope 400 through the rope hole 2011, the jump rope 400 is pressed and fixed by twisting the clamping part 300, thus completing the connection between the handle body 100, the rope threading part 200, the jump rope 400, and the clamping part 300.

[0072] Similarly, following the above procedure, assemble and connect the other handle body 100 and the other end of the jump rope 400.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
