Description

Technical Field

[0001] The utility model relates to the technical field of rope skipping, in particular to a rope skipping screw cross-penetration structure. Background Art

[0002] As a widely popular form of sport, rope skipping can be performed as an individual or multi-person sport. It is commonly seen in school sports meets, fitness competitions and other occasions. It is deeply loved by people because of its high entertainment and competitiveness.

[0003] In rope skipping competitions, athletes often need to use ropes of different thicknesses according to different training and competition requirements. However, traditional rope skipping screw designs usually only include a fixed-size perforation, which greatly limits the versatility and flexibility of the rope skipping. Whenever athletes need to change the rope, they often need to carry multiple ropes with different perforation sizes, which undoubtedly increases their inconvenience.

[0004] Therefore, a skipping rope screw cross-penetration structure is needed to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a skipping rope screw through structure, aiming to solve the problem that the screw design of a traditional skipping rope proposed in the background art usually only includes a single through hole, and this design limits the versatility and flexibility of the skipping rope.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a skipping rope screw rod through structure, comprising a rope threading rod body rotatably connected to one end of a handle for connecting a rope body, and a first through hole and a second through hole opened on the rope threading rod body and radially penetrating the rope threading rod body for threading the rope body, the first through hole and the second through hole being arranged in a vertical state, and the diameter of the second through hole is smaller than the diameter of the first through hole; since the diameter of the second through hole is smaller than the diameter of the first through hole, the rope threading rod body can be compatible with ropes of different thicknesses, thereby improving the flexibility and versatility of the skipping rope screw, and the first through hole and the second through hole arranged in a vertical state allow the user to easily pass the rope through the rope threading rod body.

[0009] In order to facilitate the fixation of the rope body, a receiving groove for accommodating the rope body is provided at the intersection of the first through hole and the second through hole; the design of the receiving groove can make the rope threading and fixing process simpler, and improve the usability of the rope skipping screw.

[0010] In order to improve the reliability of rope fixation and the convenience of replacement, a through groove connected to the accommodating groove is opened at the end of the rope threading rod body away from the handle, and a clamping structure for clamping the rope body in the accommodating groove is arranged in the through groove; by setting the clamping structure, it can be ensured that the rope body is firmly fixed in the accommodating groove, thereby increasing the stability and safety of the skipping rope during use, and reducing accidents caused by loosening or falling off of the rope body. At the same time, when the rope body needs to be replaced, the user only needs to loosen the clamping structure, and then take out or re-thread the rope body from the accommodating groove and the corresponding first perforation and second perforation, and then fix it by the clamping structure.

[0011] Preferably, in order to facilitate the use of the rope threading rod, the clamping structure includes a pressing rod axially passing through the through slot and the accommodating slot and slidably connected to the through slot, a third perforation and a fourth perforation opened on the pressing rod and corresponding to the first perforation and the second perforation respectively, and a return spring fixedly arranged on the pressing rod near one end of the through slot and fixedly connected to the inner wall of the through slot, the diameters of the third perforation and the fourth perforation are respectively consistent with the diameters of the first perforation and the second perforation; the combined design of the pressing rod, the third perforation, the fourth perforation and the return spring enables the user to easily adjust, replace and fix the rope body, thereby improving the usability and user satisfaction of the skipping rope.

[0012] Preferably, in order to facilitate the operation of the pressing rod, a pressing block is fixedly installed on the end of the pressing rod away from the return spring, and the pressing block is located on the outside of the rope threading rod body; the design of the pressing block allows the user to move the pressing rod only by gently pressing the pressing block on the outside of the rope threading rod body with his fingers or palms, thereby controlling the tightening and release of the rope body, thereby improving the convenience and efficiency of operation.

[0013] Preferably, in order to increase the limiting effect, the diameter of the pressing block is larger than the diameter of the pressing rod; due to the larger diameter of the pressing block, when the pressing rod slides in the through slot, the pressing block will form a physical limit with the opening edge of the through slot, thereby preventing the pressing rod from excessively sliding when subjected to excessive pressure or accidental impact and completely disengaging from the through slot.

[0014] Preferably, in order to enhance the holding stability, the pressing block is provided with anti-slip grooves on the side away from the pressing rod; the anti-slip grooves can increase the roughness of the surface of the pressing block, so that the user can hold the pressing block more firmly during operation, thereby effectively preventing slipping caused by sweating hands or improper operation, thereby improving the holding stability.

[0015] Preferably, in order to prevent the pressing rod from being offset or tilted, the clamping structure also includes guide blocks symmetrically fixedly connected on both sides of the pressing rod and guide grooves respectively opened in the through groove at positions corresponding to the guide blocks, and the guide blocks are slidably connected in the guide grooves; the close fit between the guide blocks and the guide grooves limits the offset or tilt of the pressing rod, so that the pressing rod can always maintain a specific angle with the through groove, thereby ensuring the normal working effect of the clamping structure.

[0016] (III) Beneficial effects

[0017] The pair of through holes is provided with a first through hole and a second through hole which are arranged in a vertical state, and the diameter of the second through hole is smaller than the diameter of the first through hole, so that the rope threading rod body can be compatible with rope bodies of different thicknesses, thereby improving the flexibility and versatility of the rope skipping screw rod;

[0018] The through-structure can ensure that the rope body is firmly fixed in the receiving groove by setting a clamping structure, thereby increasing the stability and safety of the skipping rope during use and reducing accidents caused by loosening or falling off of the rope body. At the same time, when the rope body needs to be replaced, the user only needs to loosen the clamping structure, and then take the rope body out of the receiving groove and the corresponding first perforation and second perforation or re-pass it, and then fix it with the clamping structure.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a skipping rope screw through structure, such as Figure 1-Figure 3 As shown, the pair of through structures include a rope threading rod body 2 rotatably connected to one end of the handle 1 for connecting the rope body, and a first through hole 22 and a second through hole 23 which are opened on the rope threading rod body 2 and radially penetrate the rope threading rod body 2 for threading the rope body, the first through hole 22 and the second through hole 23 are arranged in a vertical state, and the diameter of the second through hole 23 is smaller than the diameter of the first through hole 22; a receiving groove 21 for accommodating the rope body is provided at the intersection of the first through hole 22 and the second through hole 23; a through groove 24 which is connected to the accommodating groove 21 is opened at the end of the rope threading rod body 2 away from the handle 1, and a clamping structure 25 for clamping the rope body in the accommodating groove 21 is arranged in the through groove 24.

[0027] When in use, first select a rope of appropriate thickness according to the actual movement requirements. Since the diameter of the second perforation 23 is smaller than the diameter of the first perforation 22, the first perforation 22 or the second perforation 23 of appropriate diameter can be selected according to the thickness of the rope. Since the first perforation 22 and the second perforation 23 are arranged in a vertical state, and there is a receiving groove 21 at the connecting position of the first perforation 22 and the second perforation 23, the rope inserted from one end of the first perforation 22 or the second perforation 23 can easily pass through the receiving groove 21 and then pass out from the other end of the first perforation 22 or the second perforation 23. Then, through the setting of the clamping structure 25, the rope located in the receiving groove 21 can be fixed to ensure that the rope is fastened to the rope threading rod 2 for use. When it is necessary to replace the rope or adjust the length of the rope according to the movement requirements, the rope can be easily replaced or adjusted by loosening the clamping structure 25.

[0028] Specifically, the clamping structure 25 includes a pressing rod 251 axially penetrating the through slot 24 and the receiving slot 21 and slidably connected to the through slot 24, a third through hole 252 and a fourth through hole 253 provided on the pressing rod 251 and corresponding to the first through hole 22 and the second through hole 23, respectively, and a return spring 254 fixedly arranged at one end of the pressing rod 251 close to the through slot 24 and fixedly connected to the inner wall of the through slot 24. The diameters of the third through hole 252 and the fourth through hole 253 are respectively the same as the diameters of the first through hole 22 and the second through hole 23. The clamping structure 25 further comprises guide blocks 257 symmetrically fixedly connected to both sides of the pressing rod 251 and guide grooves 256 respectively arranged in the through groove 24 at positions corresponding to the guide blocks 257, and the guide blocks 257 are slidably connected in the guide grooves 256; when a thicker rope body is selected, the user can manually press the pressing rod 251, at this time, the pressing rod 251 can stably slide in the through groove 24 under the guidance of the guide grooves 256 and the guide blocks 257, and in this process, the return spring 254 will be pressed When the third through hole 252 provided on the pressing rod 251 is connected to the first through hole 22, one end of the thicker rope is passed through the third through hole 252 from one end of the first through hole 22, and then passed out from the other end of the first through hole 22. Then, the pressing of the pressing rod 251 is loosened. At this time, under the elastic rebound effect of the return spring 254, the pressing rod 251 can be stably slid back to the initial position under the guidance of the guide block 257. At this time, the rope passing through the third through hole 252 is misaligned with the first through hole 22. , so that the rope body can be clamped at the connection between the accommodating groove 21 and the through groove 24. When the length of the rope body needs to be adjusted, it is only necessary to press the pressing rod 251 to make the third through hole 252 correspond to the first through hole 22 to loosen the clamping of the rope body. When a thinner rope body needs to be replaced, it is only necessary to repeat the above steps to connect the fourth through hole 253 with the second through hole 23, and then pass the thin rope body from the second through hole 23 into the fourth through hole 253 in turn, and then pass it out from the other side of the second through hole 23, and then loosen the pressure of the pressing rod 251.

[0029] Furthermore, a pressing block 255 is fixedly installed on one end of the pressing rod 251 away from the return spring 254, and the pressing block 255 is located on the outside of the rope threading rod body 2; when the pressing rod 251 is needed, the user only needs to gently press the pressing block 255 on the outside of the rope threading rod body 2 with his fingers or palms to achieve the movement of the pressing rod 251, thereby controlling the tightening and release of the rope body, thereby improving the convenience and efficiency of operation.

[0030] Among them, in order to increase the limiting effect, the diameter of the pressing block 255 is larger than the diameter of the pressing rod 251; due to the larger diameter of the pressing block 255, when the pressing rod 251 slides in the through groove 24, the pressing block 255 will form a physical limit with the opening edge of the through groove 24, thereby preventing the pressing rod 251 from excessively sliding when subjected to excessive pressure or accidental impact, and completely disengaging from the through groove 24.

[0031] In addition, in order to enhance the holding stability, an anti-slip pattern 2551 is provided on the side of the pressing block 255 away from the pressing rod 251; the anti-slip pattern 2551 can increase the roughness of the surface of the pressing block 255, so that the user can hold the pressing block 255 more firmly during operation, thereby effectively preventing slipping caused by sweating hands or improper operation, thereby improving the holding stability.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
