Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports and cultural equipment, and in particular to an easily adjustable jump rope handle. Background Technology
[0002] Jumping rope can train limb coordination and improve cardiopulmonary function. Since users have different body types, the required jump rope length varies. Therefore, most jump ropes have an adjustment mechanism. To prevent the rope from loosening during exercise, as disclosed in CN115888004A, the adjustment mechanism uses threads or snap-fit structures to ensure its position is fixed. However, in actual product verification, it was found that the locking force generated by these fastening structures is too great, making unlocking very difficult. Adjusting the rope length is inconvenient during use, especially for young and elderly users. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes an easily adjustable jump rope handle.
[0004] The technical solution adopted in this utility model is: an easily adjustable jump rope handle, comprising...

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0027] 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.
[0028] This utility model proposes an easily adjustable jump rope handle, see reference. Figure 1 , 4 5. Embodiment 1 includes a handle body 1, which has a rotating cavity 11; a rotating shaft 2 rotatably connected to the rotating cavity 11, with part of the rotating shaft 2 inserted into the rotating cavity 11, and a rope hole 21 passing through the rotating shaft 2; the end of the rotating shaft 2 is provided with a connecting boss 22 and several adjusting holes 23, the connecting boss 22 being frustoconical in shape, and the connecting boss 22 and several adjusting holes 23 being located outside the handle body 1; the adjusting holes 23 communicating with the rope hole 21, and a positioning block 24 being provided in the adjusting holes 23; and a fixing sleeve 3 sleeved on the rotating shaft 2, with a fixing hole 31 passing through the fixing sleeve 3, and a connecting groove 32 at the tail end of the fixing hole 31.
[0029] When users need to lock the jump rope, they only need to press the fixing sleeve 3 onto the rotating shaft 2. During the insertion process, the wall of the fixing hole 31 pushes the positioning block 24 to deflect into the rope hole 21, thereby positioning the rope in the rope hole 21. After the connecting boss 22 enters the connecting groove 32, the two abut against each other to generate frictional resistance. At the same time, the contact between the fixing hole 31 and the positioning block 24 will also generate frictional resistance. The superposition of the two sets of frictional resistance will generate a moderate locking force, which will make it convenient for young and elderly users to disassemble and adjust while ensuring the stability of the handle assembly.
[0030] See Figure 2In Embodiment 2, based on Embodiment 1, several abutment grooves 221 are added to the side wall of the connecting boss 22, and several abutment bosses 33 are added to the side wall of the connecting groove 32. In the combined state, the abutment of the abutment bosses 33 and the abutment grooves 221 can increase the frictional resistance, thereby improving the connection stability between the fixed sleeve 33 and the rotating shaft 22.
[0031] See Figure 3 The positioning block 24 is wedge-shaped. One end of the positioning block 24 is fixedly connected to the adjustment hole 23, and the other end of the positioning block 24 is a free end. During the process of fitting the fixing sleeve 3, after the free end abuts against the hole wall of the fixing hole 31, it gradually deflects into the rope hole 21 to achieve the locking of the rope.
[0032] To increase the frictional resistance between the abutment boss 33 and the abutment groove 221, a number of anti-slip protrusions or anti-slip grooves can be provided on the inner side of the abutment boss 33. After the anti-slip protrusions or anti-slip grooves come into contact with the groove surface of the abutment groove 221, they can generate greater frictional resistance to ensure the stable connection between the fixed sleeve 3 and the rotating shaft 2. Similarly, anti-slip protrusions and anti-slip grooves can also be provided on the groove surface of the abutment groove 221.
[0033] See Figure 6 The rotating cavity 11 has slots 12 at both ends, and a bearing 25 is sleeved on the rotating shaft 2. The bearing 25 is locked in the slot 12, thereby realizing the rotation of the drive shaft.
[0034] See Figure 3 , 6 In Example 3, based on Example 2, a digital display component 13 is added to the rotating cavity 11. The digital display component 13 includes a circuit board 131, on which a display screen and a magnetic sensor 132 are provided. A display hole 111 is provided on the cavity wall of the rotating cavity 11, and the display screen is located in the display hole 111. A magnetic block is fixed on the rotating shaft 2, and the magnetic block rotates synchronously with the rotating shaft 2. The magnetic sensor 132 records the number of rope jumps by sensing the magnetic field changes passed by the magnetic block.
[0035] See Figure 6 The rotating cavity 11 is provided with a plurality of positioning posts 112, and the circuit board 131 is provided with a plurality of positioning grooves 133. The positioning posts 112 are engaged in the positioning grooves 133. It can be seen that the positioning posts 112 are provided with steps, and the circuit board 131 is mounted on the steps. The circuit board 131 abuts against the inside of the rotating cavity 11, thereby fixing the position of the circuit board 131.
[0036] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
