Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to an anti-torsion and long-lasting luminous skipping rope. Background Technique

[0002] With the popularization of fitness activities, skipping rope, as a simple and effective fitness method, has been widely welcomed. In order to improve the interest and attraction of skipping rope, a variety of luminous skipping rope products have emerged on the market. These luminous skipping ropes usually install a lamp wire with LED lamp beads along the rope body and use a power supply to make the lamp beads emit light, adding a unique visual effect to the skipping rope exercise.

[0003] However, in the process of using the existing luminous skipping ropes, the lamp wire (electrical conductor) often breaks from the middle, resulting in the problem that the skipping rope cannot emit light persistently, which greatly affects the use effect of the product and the user experience. In response to this problem, different merchants have made many attempts and improvements in material selection and manufacturing processes, such as using transparent plastic sleeves to protect the lamp wire and lamp beads, or encapsulating the copper wire and the luminous LED lamp beads entirely with plastic, etc. However, these methods cannot effectively solve the problem of lamp wire breakage.

[0004] After in-depth research and analysis of the above problems by the applicant, it is found that the main reason for the lamp wire breakage is that there is only one power supply connected to the current lamp wire, mostly set near one of the handles, making the weights on the left and right sides of the skipping rope uneven. As a result, when the user shakes the rope with both hands, there will be a difference in the strength of the left and right hands, which makes the skipping rope more likely to curl up. This will cause the rope body and its lamp wire to be more likely to generate torsion at the middle position. This torsion has the characteristic of opposite directions on the rope body. When the torsion accumulates to a certain extent, it will generate too much stress on the fragile lamp wire, resulting in its breakage. In view of the above reasons for the easy breakage of the lamp wire, the applicant has improved the existing technology and developed an anti-torsion luminous skipping rope, which can effectively solve the influence of lamp wire breakage, thereby improving the persistence of light emission and the durability of the luminous skipping rope. Summary of the Utility Model

[0005] Therefore, based on the above background, the utility model provides an anti-torsion luminous skipping rope, which is symmetrically arranged through independent luminous components, can greatly avoid the lamp wire breaking from the middle, and improve the persistence of light emission and the durability of the luminous skipping rope.

[0006] The technical solution provided by the utility model is as follows:

[0007] An anti-torsion luminous skipping rope, which includes two handles, a rope body is connected between the two handles. The rope body includes a first rope body and a second rope body. The first rope body and the second rope body are rotatably connected through a connecting piece; the other ends of the first rope body and the second rope body are respectively connected to the handles.

[0008] The first rope body and the second rope body respectively include independent light-emitting components.

[0009] In one implementation, the light-emitting component includes a battery, the battery is connected to electric wires forming a wire loop, and an LED lamp bead is provided on the wire loop.

[0010] In one implementation, battery cases are respectively provided on the first rope body and the second rope body, and the batteries are located inside the battery cases.

[0011] In one implementation, the battery case is connected to the handle through a connecting rope body.

[0012] In one implementation, the rope bodies of the first rope body and the second rope body between the battery case and the connecting member include electric wires and a main rope body. One end of the main rope body is connected to the battery case, and the other end is connected to the connecting member.

[0013] In one implementation, the connecting member includes a hollow first connecting body and a second connecting body:

[0014] A connecting ring plate extends from the end of the second connecting body. The connecting ring plate is sleeved in the cavity of the first connecting body, and a guiding clamping plate is provided on the connecting ring plate;

[0015] A groove adapted to the connecting ring plate is provided in the first connecting body, and a guiding ring groove adapted to the guiding clamping plate is provided on the wall of the groove.

[0016] Adopting the above technical solution, the beneficial effects are as follows:

[0017] The present utility model improves the prior art aiming at the main reasons for the breakage of the lamp wire. It adopts two independent light-emitting components symmetrically arranged. The electric wires forming the wire loops of the two light-emitting components are in a truncated and non-connected state. Fundamentally, the problem of lamp wire breakage caused by torsion at the middle position of the rope body will not occur, which can greatly reduce the breakage of the lamp wire, extend the luminous life of the light-emitting component, and improve the durability of the luminous skipping rope;

[0018] Moreover, the symmetrically arranged light-emitting components can make the weight distribution on both sides of the rope body more uniform, reduce the phenomenon of the skipping rope curling caused by uneven weight, and through the rotatable connecting member in the middle of the rope body, the torsion occurring in the middle of the rope body can be further resisted, improving the skipping experience and its durability; and the design of the double wire loop and the double power supply of the present utility model can also enable one of the lamp wires to still work normally even if it breaks, improving the durability of the skipping rope.

[0037] The present utility model will be further described below with reference to the accompanying drawings.

[0038] Embodiment 1: Refer to Figures 1 to 4 An anti-torsion luminous skipping rope as shown, which includes two handles 1. A rope body is connected between the two handles. The rope body includes a first rope body 2 and a second rope body 3. The first rope body 2 and the second rope body 3 are rotatably connected through a connector 4; the other ends of the first rope body 2 and the second rope body 3 are respectively connected to the handle 1; the first rope body 2 and the second rope body 3 respectively include independent luminous components. As Figure 3As shown, the light-emitting component includes a battery 8, the battery 8 is connected to an electric wire 711 that forms a wire loop 71, an LED lamp bead 712 is provided on the wire loop 71, and a switch 81 is provided on the wire loop. Battery cases 5 are respectively provided on the first rope body 2 and the second rope body 3, and the battery 8 is located inside the battery case 5. As Figure 2 shown, a switch button 53 corresponding to the switch is provided on the battery case 5. In specific applications, the battery can be a rechargeable battery, and a charging port 51 corresponding to the battery is provided on the battery case 5. This is conventional technology and will not be elaborated here.

[0039] The battery case 5 is connected to the handle 1 through a connecting rope body 6.

[0040] The rope bodies of the first rope body 2 and the second rope body 3 between the battery case 5 and the connector 4 include electric wires 711 and a main rope body 72. One end of the main rope body 72 is connected to the battery case 5, and the other end is connected to the connector 4. As Figure 3 shown, one end of the main rope body 72 is fixedly connected (for example, by a screw 52) to the battery case 5, and the other end is fixedly connected to the connector. The two ends of the electric wire are respectively connected to the positive and negative electrodes of the battery located inside the battery case.

[0041] The electric wires of the wire loop 71 extend in a bundle from the battery case along with the main rope body, and one end of the wire loop far from the battery case has a distance from the connector. Specifically, the electric wires and the main rope body are sheathed with a fixing sleeve 73 in a bundle. The fixing sleeve can be made of rubber material. More specifically, an adhesive is provided inside the fixing sleeve to fix the electric wires and the main rope body in a bundle to prevent them from loosening. Of course, other methods can also be used to fix the electric wires and the main rope body in a bundle to prevent them from loosening, such as using a binding band or hot melting. In order to make the weights on both sides of the first rope body and the second rope body uniform, specifically, the number of fixing sleeves 73 on the first rope body and the second rope body is the same, and the installation positions are symmetrical.

[0042] In specific implementation, the electric wires are sheathed with a protective rubber sleeve. The main rope body and the connecting rope body 6 can be rope bodies made of PVC, or braided rope bodies, or steel wire rope bodies, etc. In this embodiment, the main rope body and the connecting rope body 6 are selected as steel wire ropes twisted by multiple strands of steel wires, and a protective rubber sleeve is sheathed outside the steel wire ropes. Further, in this embodiment, a plurality of independent joint sleeves 9 are sheathed outside the rope bodies of the first rope body and the second rope body outside the battery case and the connector. On the one hand, it plays a certain role in protecting the lamp wires, and on the other hand, it makes it more interesting. The joint sleeves are made of a light-transmitting material. In the specific application process, the plurality of joint sleeves can also be replaced with an integrally formed rubber sleeve, and the method is not limited.

[0043] Specifically, the outer diameter of the main rope body is 2 - 4 mm.

[0044] Example 2: Refer to Figures 1 to 11 a torsion-resistant luminous skipping rope shown in the figure. In this embodiment, one end of the connecting rope body 6 is fixed to the battery case 5, and the other end is rotatably connected to the handle to further resist torsion. Specifically, the handle 1 includes a handle shell 11. The lower end of the handle shell 11 is provided with a hollow shell having a threaded section 111. A cylindrical shell 12 with a lower bottom seal is screwed onto the threaded section 111. The lower bottom seal has an opening 121. A rotating part 13 is arranged inside the cylindrical shell 12. The rotating part 13 includes a hollow clamping cylinder body 131 at the lower part and a hollow fixed cylinder body 132 at the upper part. A bearing 14 is arranged at the connection position between the clamping cylinder body 131 and the fixed cylinder body 132. The rotating part 13 is fixedly connected to the inner ring of the bearing. The clamping cylinder body 131 passes through the opening 121 and is clamped therein. A clamping groove is arranged on the lower bottom seal of the cylindrical shell 12, and the clamping groove cooperates with the outer ring of the bearing 14. The cylindrical shell and the rotating part can rotate relative to each other through the bearing. A fixing part 15 is clamped inside the fixed cylinder body 132. The fixing part 15 includes a guiding clamping cylinder 151 and a fixed clamping cylinder 152. The guiding clamping cylinder 151 is cylindrical. The projection of the fixed clamping cylinder 152 is similar to an ellipse. A plurality of first gaps 153 penetrating upward are arranged on the fixed clamping cylinder 152. A second gap 155 penetrating up and down is arranged on the fixed clamping cylinder and the guiding clamping cylinder 151. The width of the second gap 155 increases from top to bottom. More specifically, fixed clamping teeth 154 are arranged on the fixed clamping plates separated by the first gaps 153 on the fixed clamping cylinder 152. The outer diameter at the most protruding position of the outer arc surface of the fixed clamping plate is greater than the outer diameter of the guiding clamping cylinder 151 and is greater than or consistent with the clamping cylinder body 131. Thus, after the connecting rope body passes through the cylindrical shell, the clamping cylinder body and the fixed cylinder body of the rotating part in sequence, and the connecting rope body is placed inside the cylinder body of the fixing part through the second gap (the connecting rope body passes through the fixed clamping cylinder 152), after the guiding clamping cylinder is inserted into the clamping cylinder body until the position where the outer arc surface of the guiding clamping cylinder protrudes the most is clamped into the fixed cylinder body, at this time, after the fixed clamping cylinder is squeezed, the force is applied to fix the connecting rope body through the fixed clamping teeth.

[0045] Specifically, the fixing part 15 is made of an organic polymer material. Specifically, it can be made of a plastic with a certain elasticity, such as polyethylene or ABS. Of course, the prepared materials are not limited to the above. For example, it can also be made of a metal with a certain deformation ability, such as aluminum alloy.

[0046] Of course, the structure for rotatably mounting the connecting rope body on the handle is not limited to the structure given in this embodiment.

[0047] Example 3: Refer to Figures 1 to 4 、 Figures 11 to 14An anti-torsion luminous skipping rope as shown. In this embodiment, the specific structure of the connecting piece is given. Specifically: the connecting piece 4 includes a hollow first connecting body 41 and a second connecting body 42. At the end of the second connecting body 42, a connecting ring plate 421 extends out. The connecting ring plate 421 is sleeved in the cavity of the first connecting body 41. On the outer wall of the connecting ring plate 421, a guiding clamping plate 422 is provided. In the first connecting body 42, a groove 411 adapted to the connecting ring plate 421 is provided. On the wall of the groove 411, a guiding ring groove 412 cooperating with the guiding clamping plate 422 is provided. The guiding clamping plate is inserted into the guiding ring groove and can rotate along the guiding ring groove. Thus, the first connecting body and the second connecting body can be rotatably connected through the guiding clamping plate 422 along the guiding ring groove 412. Specifically, the first connecting body 41 and the second connecting body 42 are both hollow cylinders. Specifically, one end of the main rope body between the battery case and the connecting piece is fixedly connected to the connecting piece by screws. Corresponding screw holes 43 are provided on the connecting piece. Specifically, after one end of the main rope body passes through the cylinder of the connecting piece, the screw passes through the screw hole and presses on the main rope body to fix it.

[0048] Of course, the structure of the connecting piece is not limited to the above. For example, the structure of the connecting piece can also be as follows (not shown in the attached drawings): the connecting piece 4 includes a hollow first connecting body 41 and a second connecting body 42. The first connecting piece and the second connecting piece can be rotatably connected through a bearing. For example, the first connecting body and the second connecting body are cylinders with bottom seals. Screw holes are provided on the cylinder without a bottom seal. A connecting column is provided on the second connecting body. A bearing is installed on the bottom seal of the first connecting body. The connecting column passes through and is fixedly connected to the inner ring of the bearing.

[0049] The connecting piece can be made of stainless steel.

[0050] The utility model improves the prior art aiming at the main reasons for the lamp wire breakage. Through the symmetrical setting of the double-wire loop and its double power supplies, the electric wires forming the wire loop of the two luminous components are in a truncated and non-connected state. Fundamentally, the problem of lamp wire breakage caused by torsion in the middle position of the rope body will not occur, which can greatly reduce the lamp wire breakage, extend the luminous life of the luminous component, and improve the persistence of the skipping rope's luminescence.

[0051] And it makes the weight distribution on the left and right sides of the rope body more uniform, reduces the phenomenon of the skipping rope curling due to uneven weight, and through the rotatable connecting piece in the middle of the rope body, resists the torsion occurring in the middle of the rope body, reduces the probability of the lamp wire breakage, and improves the durability and service life of the luminous skipping rope.

[0052] Although the double-wire loop and its dual-power supply design of the present utility model may be slightly higher in initial cost than the single-power supply design, considering the actual situation that the single-loop and single-power supply skipping ropes are very likely to require overall replacement or be discarded due to the breakage of the lamp wires after a period of use, the double-wire loop and its dual-power supply design of the present utility model will be more cost-effective in long-term use.

[0053] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, creatively design structural manners and embodiments similar to the technical solution, they shall fall within the protection scope of the present utility model.
