Description

Technical Field

[0001] The utility model relates to the technical field of skipping ropes, in particular to a skipping rope structure based on the principle of conservation of angular momentum. Background Art

[0002] In the prior art, a skipping rope is a sports game in which one or more people make various jumping movements in a swinging rope loop. Skipping rope exercise is an excellent fitness exercise that can effectively train an individual's reaction and endurance, help maintain an individual's posture, beauty and coordination, so as to achieve the purpose of strengthening the body. The equipment for skipping rope exercise is very simple, only a rope, light clothes and a pair of comfortable sports shoes are needed; in addition, the venue required for skipping rope is not large, there is no need to rent a special venue, and the number of participants is not limited. It can be carried out alone or by multiple people. In order to achieve better exercise effects, for different groups of people and different exercise purposes, the types and functions of skipping ropes are increasing day by day. Weighted skipping ropes have emerged in recent years. Different from traditional skipping ropes, weighted skipping ropes are divided into two types. One is to increase the weight on the rope body, such as bamboo joint skipping ropes, sandbag skipping ropes, etc.; the other is to increase the weight on the handle. However, in the existing handle-weighted skipping ropes, the increased weight on the handle is relatively fixed and cannot be adjusted arbitrarily according to the user's physical fitness and training intensity. At the same time, the user cannot conveniently calculate their own exercise intensity and make reasonable arrangements for subsequent training.

[0003] The Chinese utility model patent with the application number: 202023338946.9 discloses a cordless fitness skipping rope with adjustable weight, including a skipping rope body.

The plug block is arranged at the lower end of the handle body, the connecting column is arranged at the upper end of the handle body, the mounting block is arranged at the upper end of the connecting column, and the solid column is arranged on one side of the handle body; a threaded column is arranged at the upper end of the plug block. The handle body includes an internal thread and a storage frame. The internal thread is arranged on the inner wall of the handle body, and the internal thread is in threaded connection with the threaded column. The storage frame is arranged inside the handle body. However, although this cordless fitness skipping rope with adjustable weight has a weight block structure, the installation of its weight block requires the user to adjust and assemble it by themselves, the assembly method is relatively cumbersome, the use method is relatively single, and the fitness interest is poor.

Wherein, the handle plug 11 is used as a plug structure at one end of the handle housing 1, so that the handle housing 1 forms a closed housing structure.

[0030] It further includes anti-slip stripes 12. There are several groups of anti-slip stripes 12 which are evenly spaced and arranged on the side of the handle housing 1 and are embedded in the handle housing 1. Wherein, the anti-slip stripes 12 are used as anti-slip structures on the handle housing 1 to improve the anti-slip effect of the handle housing 1.

[0031] Wherein, a safety rope can be tied to the handle plug 11, so as to prevent the user from dropping the hand when using this skipping rope structure for exercise.

The schematic diagram of the cooperation between the skipping rope module and the handle housing 1 in Embodiment 2 of the present utility model is as Figure 3 shown.

[0034] Working principle:

[0035] When using this skipping rope structure for skipping exercise, shake the handle, the skipping rope module rotates, and the skipping rope module drives the mounting rotor 4 to rotate through the belt transmission gearbox 6. The speed ratio of the gearbox is 64:1. According to the principle of conservation of angular momentum, when the speed of the skipping rope module is faster, the potential energy generated by the counterweight module is greater, that is, the heavier the handle is, which has the same effect as a wrist strength ball. During the skipping process, the counterweight of the handle part can be adjusted by controlling the rotation speed of the skipping rope, and the skipping rope module can be selected according to actual use requirements to form a rope skipping or a cordless skipping.

[0036] The beneficial effects of the present utility model are that the structure is simple, there is a shaft module cooperating with a counterweight module, and based on the principle of conservation of angular momentum, an adaptive skipping rope structure with a greater speed and greater potential energy is formed. There is no need for the user to adjust and assemble by himself, that is, the faster you jump, the heavier it is, so as to meet the user's need to adjust different gravities during the skipping process. It is flexible to use, can combine the skipping rope with the wrist strength ball, double the fitness effect and increase the use interest at the same time. There is a skipping rope module, and a rope structure or a cordless structure can be selected according to the use requirements.
