Description
Technical Field
[0001] The utility model relates to the technical field of skipping rope equipment, in particular to a cordless skipping rope with a centrifugal component. Background Art
[0002] Skipping rope is an ancient sport that has been passed down to this day. Now, skipping rope is not only an entertainment sport, but also one of the items in the physical education examinations of primary and secondary schools.
[0003] An ordinary skipping rope generally has two handles, which are connected by a rope. The skipping rope movement is carried out by swinging the rope. However, generally the rope is relatively long, so a certain height space is required when swinging. Moreover, when the rope swings, it will impact the ground and generate noise. Therefore, an ordinary skipping rope not only has certain requirements for the use scenario, but also easily affects the people nearby.
[0004] Later, people designed a cordless skipping rope. The biggest difference from an ordinary skipping rope is that the long rope body between the two handles is cancelled. When relying on swinging the ball head of the handle of the cordless skipping rope, the centrifugal force generated by the ball head makes people feel the same sense of weight as the long rope body, so as to achieve the same hand feeling as an ordinary skipping rope.
[0005] However, an ordinary cordless skipping rope needs to be assembled, so the production cost is relatively high. Therefore, an integrated cordless skipping rope appeared on the market. However, for an ordinary and conventional integrated cordless skipping rope, the centrifugal force generated when swinging is generally small and only suitable for ordinary people. For some relatively professional people, they need a relatively strong sense of centrifugation. Therefore, this kind of integrated cordless skipping rope with relatively small centrifugal force and less obvious centrifugal feeling cannot meet their needs. Once there is no centrifugal feeling, then for the user, the effect of skipping rope exercise is not so obvious.
[0006] Therefore, the existing integrated cordless skipping rope has the problem of weak centrifugal feeling and needs further improvement to enhance the centrifugal feeling during the skipping rope process. Summary of the Utility Model
[0007] The utility model aims at the above problems and provides a cordless skipping rope with a centrifugal component.
[0008] The technical solution adopted by the utility model is as follows:
[0009] The present application provides a cordless skipping rope with a centrifugal component, including a swinging part, a connecting part and a holding part. The swinging part is arranged at one end of the connecting part, and the holding part is arranged at the other end of the connecting part.
[0010] The swinging part, the connecting part and the holding part are integrally formed;
[0011] The connecting part is softer than the handheld part, and the connecting part is softer than the swinging part.
[0012] A centrifugal part is provided on one side of the swinging part.
[0013] Due to the design of the centrifugal part, the overall center of gravity of the swinging part will shift to the side of the centrifugal part, thus achieving an eccentric effect. Therefore, when the swinging part is swung, due to the shift of the center of gravity, a stronger centrifugal feeling towards the outside can be generated, thereby achieving the purpose of improving the skipping effect and meeting the usage requirements of relatively professional people.
[0014] During actual production, since the swinging part, the connecting part, and the handheld part are integrally formed, the assembly step is not required. This not only saves the time required for assembly but also saves the labor cost brought by assembly. At the same time, since the three are integrally formed, they will not separate from each other, thus avoiding the danger of parts being thrown out and injuring people.
[0015] In addition, the connecting part is the softest. So when holding the handheld part with the hand and swinging the swinging part, the swinging part generates a centrifugal motion, which will drive the connecting part to twist and deform, thereby ensuring that the swinging part can perform centrifugal swinging smoothly and continuously, and enabling the skipper to feel the same weight as a regular skipping rope.
[0016] Further, the centrifugal part and the swinging part are detachably connected by plugging or clamping. The detachable connection method can meet the different needs of ordinary skippers and professional skippers. That is:
[0017] When an ordinary skipper uses it, the centrifugal part can be disassembled and the ordinary integrated cordless skipping rope can be used for exercise.
[0018] When a professional skipper uses it, the centrifugal part can be installed and the cordless skipping rope with a centrifugal component can be used for exercise.
[0019] Further, a T-shaped part extends outward from the end face of the centrifugal part facing the swinging part. The T-shaped part includes a first extension section and a second extension section;
[0020] An inwardly provided T-shaped groove is formed on the end face of the swinging part facing the centrifugal part. The T-shaped groove includes a first extension groove and a second extension groove;
[0021] The T-shaped part is plugged or clamped with the T-shaped groove. At this time, the first extension section is located in the first extension groove, and the second extension section is located in the second extension groove.
[0022] The T-shaped part and the T-shaped groove can achieve stable connection by using the T-shaped structure and are not prone to detachment. Moreover, multiple T-shaped structures can be added to improve the stability of the connection.
[0023] Furthermore, the outer diameter of the first extension section is greater than the inner diameter of the first extension groove. When the first extension section is located within the first extension groove, a wrapped and clamped effect will be formed; and the contact surfaces of the two are completely fitted, greatly increasing the friction between them. Thus, the connection strength and stability are further ensured.
[0024] Furthermore, the edge of the end face of the second extension section facing the first extension section is a right angle. The design of the right angle prevents the T-shaped structure from separating due to a smooth connection, increasing the difficulty of separating the T-shaped structure. Therefore, the stability of the connection is further ensured.
[0025] The edge of the end face of the second extension section facing away from the first extension section is a rounded corner. The design of the rounded corner enables the second extension section to more conveniently and smoothly enter the second extension groove when the T-shaped structure is connected.
[0026] Therefore, the T-shaped structure can be conveniently inserted through the design of the rounded corner and can prevent separation through the design of the right angle.
[0027] Furthermore, the swinging part, the connecting part, and the handheld part are all made of the same material. The same material facilitates production. During the molding process, only one material is required and there is no need to replace other materials. Especially when compared with multi-material or multi-color molding, a lot of time can be saved and the production efficiency can be improved.
[0028] Furthermore, the swinging part, the connecting part, and the handheld part are all made of silica gel material;
[0029] The weight of the silica gel of the connecting part is less than the weight of the silica gel of the handheld part, and the weight of the silica gel of the connecting part is less than the weight of the silica gel of the swinging part.
[0030] During molding, by controlling the amount of silica gel entering each position, different silica gel weights at different positions can be achieved, making the connecting part the softest, and thus ensuring that the swinging part can perform continuous and smooth centrifugal motion.
[0031] Furthermore, the swinging part, the centrifugal part, the connecting part, and the handheld part are all made of silica gel material. The soft gel material has a good hand feeling and there is no rough feeling when held by hand.
[0032] The swinging part, the centrifugal part, the connecting part and the handheld part are integrally formed. Integral forming eliminates the need for subsequent assembly, which can save costs. Moreover, the integrally formed structure prevents accidental detachment of components due to unstable connection. Therefore, there is no risk of components being accidentally thrown and injuring others.
[0033] Furthermore, the connection between the swinging part and the connecting part is a transition arc. The connection between the handheld part and the connecting part is also the transition arc. The outer surface of the transition arc is provided with a reinforcing rib. The reinforcing rib can improve the connection strength and prevent the connection from being broken by the centrifugal force generated during centrifugal motion, thus extending the service life of the cordless skipping rope.
[0034] Furthermore, the reinforcing rib is integrally formed with the swinging part, the connecting part and the handheld part. Although the reinforcing rib is added, it is also integrally formed, so it will not reduce the production speed or affect the production efficiency.
[0035] The beneficial effects of the present utility model are as follows:
[0036] (1) The design of the centrifugal part is added to enhance the centrifugal feeling during the skipping process, thereby meeting the usage requirements of more professional users.
[0037] (2) The centrifugal part, the swinging part, the connecting part and the handheld part are integrally formed. This not only saves the subsequent assembly cost but also effectively prevents accidental separation of components during swinging, avoiding the risk of injury.
[0038] (3) By providing a detachable centrifugal part and an integrally formed centrifugal part, the cordless skipping rope with a centrifugal component can meet the usage requirements of different groups of people.
[0039] (4) Integrally formed reinforcing ribs are provided at the positions between the swinging part, the connecting part and the handheld part, further ensuring the connection strength between them and reducing the risk of being broken due to centrifugal motion. Description of the Drawings

[0048] The present utility model will be described in detail below with reference to the accompanying drawings.
[0049] Embodiment 1
[0050] As Figures 1 to 2 shown, the present application provides a cordless skipping rope with a centrifugal component, including a swinging part 1, a connecting part 2 and a hand-held part 3. The swinging part 1 is arranged at one end of the connecting part 2, and the hand-held part 3 is arranged at the other end of the connecting part 2.
[0051] The swinging part 1 can be spherical, or can be other various shapes such as cylindrical, conical, rectangular body, etc. It can also be other various bionic shapes, for example: the shapes of various organisms such as flowers, fish, birds, etc. It can also be the appearance of various models such as spaceships, airplanes, cars, etc.
[0052] A centrifugal part 5 is arranged on one side of the swinging part 1. Due to the design of the centrifugal part 5, the overall center of gravity of the swinging part 1 will shift to the side of the centrifugal part 5, thus achieving the effect of eccentricity. Therefore, when the swinging part 1 is swung, due to the shift of the center of gravity, a stronger centrifugal feeling towards the outside can be generated, thereby achieving the purpose of improving the skipping effect and meeting the usage requirements of relatively professional people.
[0053] The outer diameter of the handheld part 3 gradually increases from one end of the handheld part 3 facing the connecting part 2 to the other end. The gradually increasing outer diameter enables the position of the maximum outer diameter of the handheld part 3 to be at the rearmost end of the handheld part 3. When the hand holds the handheld part 3, the rearmost end of the handheld part 3 is exposed outside the hand-holding position and at the end away from the swinging part 1. Therefore, it can effectively prevent the entire cordless skipping rope from falling out of the hand and avoid hurting others by being flung away.
[0054] The swinging part 1, the connecting part 2, and the handheld part 3 are integrally formed.
[0055] During actual production, since the swinging part 1, the connecting part 2, and the handheld part 3 are integrally formed, the assembly step is not required. This not only saves the time required for assembly but also saves the labor cost brought by assembly. At the same time, due to the integral formation of the three parts, they will not separate from each other, thus avoiding the danger of parts being flung out and hurting people.
[0056] The swinging part 1, the connecting part 2, and the handheld part 3 are all solid structures inside. The solid design can save a lot of mold costs when making the corresponding molds because the structure is the simplest.
[0057] The swinging part 1, the centrifugal part 5, the connecting part 2, and the handheld part 3 are integrally formed. Integral formation does not require subsequent assembly, which can save more costs. Moreover, the integrally formed structure will not have the accidental detachment of parts caused by unstable connection. Nor will there be the danger of parts being accidentally flung out and hurting others.
[0058] The swinging part 1, the centrifugal part 5, the connecting part 2, and the handheld part 3 are all solid structures.
[0059] The connection between the swinging part 1 and the connecting part 2 is a transitional arc; the connection between the handheld part 3 and the connecting part 2 is also a transitional arc. The design of the arc at the transition position can make the transition between the two more natural and beautiful, and it is not easy to produce a sharp feeling like distinct edges and corners.
[0060] The connecting part 2 is softer than the handheld part 3, and the connecting part 2 is softer than the swinging part 1.
[0061] The connecting part 2 is the softest. So when holding the handheld part 3 with the hand and swinging the swinging part 1, the swinging part 1 generates a centrifugal motion, which will drive the connecting part 2 to twist and deform, thereby ensuring that the swinging part 1 can perform a smooth and continuous centrifugal swing, and further enabling the rope-skipping person to feel the same sense of weight as an ordinary skipping rope.
[0062] The swinging part 1, the connecting part 2, and the handheld part 3 are all made of the same material. Using the same material facilitates production. During the molding process, only one material is needed without the need to change to other materials. Especially when compared with multi-material or multi-color molding, a lot of time can be saved and production efficiency can be improved.
[0063] The swinging part 1, the connecting part 2, and the handheld part 3 are all made of soft rubber materials, such as: TPR, TPE, silicone, etc. Soft rubber materials have a good feel and there will be no rough feeling when held by hand.
[0064] The swinging part 1, the connecting part 2, and the handheld part 3 are all made of silicone materials;
[0065] The swinging part 1, the centrifugal part 5, the connecting part 2, and the handheld part 3 are all made of the same material, generally soft rubber materials, such as: TPR, TPE, silicone, etc. Soft rubber materials have a good feel and there will be no rough feeling when held by hand.
[0066] The silicone weight of the connecting part 2 is less than the silicone weight of the handheld part 3, and the silicone weight of the connecting part 2 is less than the silicone weight of the swinging part 1.
[0067] During molding, by controlling the amount of silicone entering each position, different silicone weights at different positions are achieved, making the connecting part 2 the lightest and softest, thereby ensuring that the swinging part 1 can perform continuous and smooth centrifugal motion.
[0068] When in use, just hold the handheld part 3 with the hand, place the centrifugal part 5 on the side away from the human body, and then swing the swinging part 1 in a circular motion to make the swinging part 1 perform centrifugal motion. Due to the presence of the centrifugal part 5, compared with ordinary cordless skipping ropes, there will be a stronger centrifugal feeling. Under the action of centrifugal force, the swinging part 1 will drive the connecting part 2 to twist and deform, and then make the rope skipper feel the same weight as an ordinary skipping rope. Since the whole is molded with silicone and the connecting part 2 is the softest, no breakage will occur. Moreover, after stopping the swinging, the elasticity of the soft rubber can be used to make the cordless skipping rope return to its original state.
[0069] In addition, since the long rope body is cancelled, the skipping rope has no requirement for the venue and there will be no trouble of the rope body hitting the ground and generating noise.
[0070] Embodiment 2
[0071] As Figures 3 to 6 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment,
[0072] The centrifugal part 5 and the swinging part 1 are detachably connected by plugging or clamping. The detachable connection method can meet the different needs of ordinary rope skipping users and professional rope skipping users at the same time. That is:
[0073] When an ordinary rope skipping user uses it, the centrifugal part 5 can be detached, and an ordinary integrated cordless skipping rope can be used for exercise.
[0074] When a professional rope skipping user uses it, the centrifugal part 5 can be installed, and a cordless skipping rope with a centrifugal component can be used for exercise.
[0075] A T-shaped part 51 extends outward from the end face of the centrifugal part 5 facing the swinging part 1. The T-shaped part 51 includes a first extension section 511 and a second extension section 512;
[0076] An inwardly provided T-shaped groove 11 is formed on the end face of the swinging part 1 facing the centrifugal part 5. The T-shaped groove 11 includes a first extension groove 111 and a second extension groove 112;
[0077] The T-shaped part 51 is plugged or clamped with the T-shaped groove 11. At this time, the first extension section 511 is located in the first extension groove 111, and the second extension section 512 is located in the second extension groove 112.
[0078] The T-shaped part 51 and the T-shaped groove 11 can achieve a stable connection by using the T-shaped structure and are not prone to detachment. Moreover, multiple T-shaped structures can be added to improve the connection stability.
[0079] Among them:
[0080] The outer diameter of the first extension section 511 is greater than the inner diameter of the first extension groove 111. When the first extension section 511 is located in the first extension groove 111, a wrapped and clamped effect will be formed; and the contact surfaces of the two are completely fitted, greatly increasing the friction between the two. Thus, the connection strength and stability are further ensured.
[0081] The edge of the end face of the second extension section 512 facing the first extension section 511 is a right angle. The design of the right angle prevents the T-shaped structure from accidentally separating due to a smooth connection, increasing the difficulty of separating the T-shaped structure. Therefore, the connection stability is further ensured.
[0082] The edge of the end face of the second extension section 512 facing away from the first extension section 511 is a rounded corner. The design of the rounded corner enables the second extension section 512 to enter the second extension groove 112 more conveniently and smoothly when the T-shaped structure is connected.
[0083] Therefore, the T-shaped structure can facilitate entry through the design of the rounded corners and prevent separation through the design of the right angles.
[0084] Embodiment 3
[0085] The difference between this embodiment and Embodiment 1 is that in this embodiment, reinforcing ribs (not shown in the figure) are provided on the outer surface of the transition arc. The reinforcing ribs can improve the connection strength and are not easily broken at the connection due to the centrifugal force generated by centrifugal motion, so the service life of the cordless skipping rope can be extended.
[0086] The reinforcing ribs are integrally formed with the swinging part 1, the connecting part 2, and the handheld part. Although the addition of the reinforcing ribs is provided, since it is also integrally formed, the production speed will not be reduced and the production efficiency will not be affected.
[0087] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applied to other related technical fields, shall be equally included in the protection scope of the present invention.
