Description
Technical Field
[0001] The utility model relates to the technical field of skipping rope equipment, in particular to a cordless skipping rope. Background Art
[0002] Skipping rope is a sports game in which one person or a group of people make various jumping movements in a swinging rope. This game was called "penetrating rope" in the Tang Dynasty, "jumping rope" in the Song Dynasty, "jumping a hundred ropes", "jumping white ropes", "jumping horse ropes" in the Ming Dynasty, "rope flying" in the Qing Dynasty, and "skipping rope" after the late Qing Dynasty. As an ancient Han folk entertainment activity, it 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 examination for 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, during the swinging process of the rope, it will collide with 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 the cordless skipping rope relies on swinging the ball head of the handle, 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, during the production process of the cordless skipping rope, the ball head, connecting rope and handle need to be assembled with each other. The assembly not only takes time, but also requires a large amount of manual assembly cost. Moreover, during the assembly process, if the process fails to meet the requirements and is not assembled in place, during the subsequent skipping rope process, it is very easy for the ball head to separate from the connecting rope, or for the ball head to separate from the handle with the connecting rope. Since it is during the skipping rope process and separation occurs during swinging, there is a very high risk of injuring the people nearby.
[0006] Therefore, the existing cordless skipping ropes are not only troublesome to assemble, costly, but also may pose a danger of injuring people. So, the existing cordless skipping ropes need further improvement. Content of the Utility Model
[0007] The utility model aims at the above problems and proposes a cordless skipping rope.
[0008] The technical solution adopted by the utility model is as follows:
[0009] The present application provides a cordless skipping rope, which includes a swinging part, a connecting part and a handheld part. The swinging part is arranged at one end of the connecting part, and the handheld part is arranged at the other end of the connecting part.
[0010] The swinging part, the connecting part and the handheld 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] 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 hurting people.
[0013] 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 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 further enabling the rope skipper to feel the same sense of weight as that of an ordinary skipping rope.
[0014] 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 forming process, only one material is needed without the need to replace other materials. Especially when compared with multi-material or multi-color forming, it can save a lot of time and improve production efficiency.
[0015] Furthermore, the swinging part, the connecting part and the handheld part are all made of soft rubber material or cord body.
[0016] The soft rubber material has a good hand feeling and there is no rough feeling when held by hand. The cord body can be formed by means of knitting, bundling, winding, etc.
[0017] Furthermore, the swinging part, the connecting part and the handheld part are all made of silicone material;
[0018] The silicone density of the connecting part is less than the silicone density of the handheld part, and the silicone density of the connecting part is less than the silicone density of the swinging part.
[0019] During forming, by controlling the amount of silicone entering each position, different silicone densities at different positions are achieved, making the connecting part the softest, and thus ensuring that the swinging part can perform centrifugal motion continuously and smoothly.
[0020] Furthermore, the swinging part, the connecting part, and the handheld part are all made of silica gel material;
[0021] The silica gel weight of the connecting part is less than that of the handheld part, and the silica gel weight of the connecting part is less than that of the swinging part.
[0022] 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.
[0023] Furthermore, the outer diameter of the handheld part gradually increases from one end facing the connecting part to the other end. The gradually increasing outer diameter can make the position of the maximum outer diameter of the handheld part at the rearmost end of the handheld part, so it can effectively prevent the entire cordless skipping rope from falling out of the hand and also avoid flying and hitting others.
[0024] Furthermore, the swinging part, the connecting part, and the handheld part are all solid structures inside. The solid design, due to its simplest structure, can save a lot of mold costs when making the corresponding molds.
[0025] 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 a transition 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 with distinct edges and corners.
[0026] Furthermore, reinforcing ribs are provided on the outer surface of the transition arc. The reinforcing ribs can improve the connection strength and are not easy to be broken at the connection due to the centrifugal force generated by the centrifugal motion, so the service life of the cordless skipping rope can be extended.
[0027] Furthermore, the reinforcing ribs are integrally formed with the swinging part, the connecting part, and the handheld part. Although the reinforcing ribs are added, they are also integrally formed, so the production speed will not be reduced and the production efficiency will not be affected.
[0028] The beneficial effects of the present utility model are:
[0029] (1) Integrally forming the swinging part, the connecting part, and the handheld part not only reduces the production cost but also ensures that each part will not separate from each other and there is no danger of flying and hitting others.
[0030] (2) By setting materials with different densities or weights, the connecting part is made the softest position, thus ensuring that the swinging part can perform continuous and smooth centrifugal motion.
[0031] (3) At the positions among the swinging part, the connecting part and the handheld part, the integrally formed reinforcing ribs are provided, further ensuring the connection strength among them and not easily having the risk of being forcibly broken due to centrifugal motion among them.

[0037] The present utility model will be described in detail below with reference to the accompanying drawings.
[0038] Embodiment 1
[0039] As Figures 1 to 2 shown, the present application provides a cordless skipping rope, including a swinging part 1, a connecting part 2 and a handheld part 3. The swinging part 1 is arranged at one end of the connecting part 2, and the handheld part 3 is arranged at the other end of the connecting part 2.
[0040] The swinging part 1 can be spherical, or other various shapes such as cylindrical, conical, rectangular body, etc. It can also be other various bionic shapes, such as: 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.
[0041] 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 can make the position where the maximum outer diameter of the handheld part 3 is located 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 far from the swinging part 1. Therefore, it can effectively prevent the whole cordless skipping rope from falling off the hand and avoid hurting others by flying off.
[0042] The swinging part 1, the connecting part 2 and the handheld part 3 are integrally formed.
[0043] During actual production, since the swinging part 1, the connecting part 2, and the handheld part 3 are integrally formed, there is no need for the assembly step. This not only saves the time required for assembly but also reduces the labor cost associated with assembly. At the same time, because they are integrally formed, they will not separate from each other, thus avoiding the risk of the components being thrown out and injuring people.
[0044] The swinging part 1, the connecting part 2, and the handheld part 3 are all solid structures inside. The solid design, due to its simplest structure, can save a great deal of mold cost when making the corresponding molds.
[0045] 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.
[0046] The connecting part 2 is softer than the handheld part 3, and the connecting part 2 is softer than the swinging part 1.
[0047] 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, thus ensuring that the swinging part 1 can perform centrifugal swinging smoothly and continuously, and then enabling the rope skipper to feel the same sense of weight as a normal skipping rope.
[0048] The swinging part 1, the connecting part 2, and the handheld part 3 are all made of the same material. 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, it can save a lot of time and improve production efficiency.
[0049] 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 hand feeling and there is no rough feeling when held by hand.
[0050] The swinging part 1, the connecting part 2, and the handheld part 3 are all made of silicone materials;
[0051] The silicone density of the connecting part 2 is less than the silicone density of the handheld part 3, and the silicone density of the connecting part 2 is less than the silicone density of the swinging part 1.
[0052] During molding, by controlling the amount of silicone entering each position, different silicone densities at different positions are achieved, making the connecting part 2 the softest, and thus ensuring that the swinging part 1 can perform centrifugal motion continuously and smoothly.
[0053] When in use, just hold the handheld part 3 with your hand, and then swing the swinging part 1 in a circular motion to make the swinging part 1 perform a centrifugal motion. Under the action of the centrifugal force, the swinging part 1 will drive the connecting part 2 to twist and deform, so that the rope skipper can feel the same weight as that of an ordinary skipping rope. Since the whole is formed by silicone, and the connecting part 2 is the softest, it will not break. 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.
[0054] In addition, since the long rope body is cancelled, the skipping rope has no requirement for the site, and there will be no trouble of the rope body hitting the ground to generate noise.
[0055] Embodiment 2
[0056] The difference between this embodiment and Embodiment 1 is that in this embodiment,
[0057] the swinging part 1, the connecting part 2 and the handheld part 3 are all made of silicone material;
[0058] 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.
[0059] During molding, by controlling the amount of silicone entering each position, different silicone weights at different positions can be achieved, so that the connecting part 2 is the lightest and softest, and thus ensure that the swinging part 1 can perform continuous and smooth centrifugal motion.
[0060] Embodiment 3
[0061] The difference between this embodiment and Embodiment 1 is that in this embodiment, the swinging part 1, the connecting part 2 and the handheld part 3 are all made of rope bodies. The rope bodies can be integrally formed by means of knitting, bundling, winding, etc. to form the swinging part 1, the connecting part 2 and the handheld part 3.
[0062] Embodiment 4
[0063] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the transition arc outer surface is provided with a reinforcing rib 4. The reinforcing rib 4 can improve the connection strength and is not easy to break the connection due to the centrifugal force generated by the centrifugal motion, so the service life of the cordless skipping rope can be extended.
[0064] The reinforcing rib 4 is integrally formed with the swinging part 1, the connecting part 2 and the handheld part. Although the arrangement of the reinforcing rib 4 is added, since it is integrally formed, the production speed will not be reduced and the production efficiency will not be affected either.
[0065] 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 similarly included in the protection scope of the present invention.
