Description

Technical Field

[0001] This invention relates to the field of jump rope technology, and in particular to a manufacturing process for a jump rope. Background Technology

[0002] Jump rope is a common fitness product in daily life. It can be used for students' physical exercise as well as for professional competitive sports. It can help you maintain a certain rhythm during exercise, ensure your breathing rate, and make your training last longer.

[0003] Jump ropes are typically adjusted for length by wrapping them around the handle at different points. However, this single wrapping method doesn't guarantee a secure connection between the rope and the handle, and the wrapping may loosen during jumps. Furthermore, adjusting the rope length using wrapping limits the range of adjustment; if the rope ends are too long, it can obstruct movement during jumps. Therefore, the adjustable range of the jump rope is relatively small and not suitable for multi-purpose use. Summary of the Invention

[0004] This invention discloses a manufacturing process for a jump rope, aiming to solve the technical problem that the adjustable range of jump ropes is relatively small and cannot be adapted to multiple uses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A manufacturing process for a jump rope includes a jump rope body with handles connected to both ends. The jump rope body also includes an adjustment mechanism and two weight-bearing mechanisms, located at the center of the jump rope body and symmetrically opposite to the adjustment mechanism. The adjustment mechanism contains a traction mechanism. The adjustment mechanism includes a second external threaded sleeve and two semi-circular merging plates. The inner wall of the second external threaded sleeve is connected to the jump rope body via a connecting frame. The outer wall of the jump rope body is simultaneously fitted with a first clamping groove and a second clamping groove. The bottom ends of the semicircular merging plates are respectively fixedly connected to merging rings, and the two merging rings can be clamped on the first clamping groove and the second clamping groove. Limiting blocks are respectively provided at the same position of the first clamping groove and the second clamping groove. The bottom ends of the two merging rings are simultaneously connected to connecting pieces, and the mating part of the two merging rings is provided with a limiting groove, and the limiting block is engaged in the limiting groove. The outer walls of the two semicircular merging plates are simultaneously provided with external threads, and the outer walls of the semicircular merging plates are engaged with a second internal thread sleeve through the external threads. The second internal thread sleeve is simultaneously engaged with the outside of the second external thread sleeve.

[0007] By incorporating an adjustment mechanism, the semi-circular merging plate can be clamped in the first and second clamping slots via a merging ring. A connection between the semi-circular merging plate and the second external threaded sleeve can be established through the second internal threaded sleeve. Since the second external threaded sleeve is fixed to the jump rope body and the semi-circular merging plate is simultaneously limited and connected to the jump rope body, excess jump rope body can be inserted into the second external threaded sleeve. After establishing a connection through the second internal threaded sleeve, the jump rope body can be shortened. Furthermore, based on the different positions of the first and second clamping slots, the jump rope can be adjusted to three lengths, suitable for children, adults, and large rope jumps, respectively, thus optimizing the multi-functionality of the jump rope.

[0008] In a preferred embodiment, the traction mechanism includes a damping collar, which is fixed to the inner wall of a second external threaded sleeve. An outer sleeve is movably inserted inside the damping collar, and a second inner support rod is movably fitted inside the outer sleeve. One end of the second inner support rod is fixedly connected to a first inner support rod, and one end of the first inner support rod passes through the outer sleeve and is connected to a circular support plate. The diameter of the first inner support rod is smaller than that of the second inner support rod, and a spring is provided between the second inner support rod and the outer sleeve. The other end of the second inner support rod is connected to a connecting rod via a hinge seat. One end of the outer sleeve is fixedly connected to a support frame, and the middle section of the connecting rod is movably connected to the support frame via a connecting rod.

[0009] With the traction mechanism in place, the traction mechanism can assist in the rope threading process. Pressing the circular support plate causes the spring to contract, which in turn causes the second inner support rod to push out, thereby extending the connecting rod laterally and inserting it into the jump rope body inside the second external threaded sleeve, where it is used as a hook. Thus, when the outer sleeve is pulled outward along the damping ring, the jump rope body can be pulled outward, thereby assisting in the folding of the jump rope body and effectively reducing the difficulty of operation.

[0010] In a preferred embodiment, the load-bearing mechanism includes a connecting sleeve, one end of which is fixedly connected to a first external threaded sleeve, and the other end of which is fixedly connected to a plurality of grippers. The connecting sleeve and the first external threaded sleeve are simultaneously fixedly sleeved on the outside of the jump rope body. A limiting sleeve is movably sleeved on the outside of the connecting sleeve, and a tapered groove is provided inside the limiting sleeve. A snap-fit ​​groove is provided on one side of the inner wall of the limiting sleeve. A snap-fit ​​strip is movably snapped in the snap-fit ​​groove, and a first internal threaded sleeve is fixedly connected to one side of the outer wall of the snap-fit ​​strip. The first internal threaded sleeve is movably engaged with the outside of the first external threaded sleeve.

[0011] The specific steps include the following:

[0012] S1: The jump rope is disassembled into a handle, the jump rope body, the weight-bearing mechanism, the adjustment mechanism, and the traction mechanism.

[0013] S2: The handle and jump rope body are injection molded and stretched.

[0014] S3: Fabricate all parts of the load-bearing mechanism, adjustment mechanism, and traction mechanism, and assemble them;

[0015] S4: Each jump rope body is equipped with two load-bearing mechanisms and one adjustment mechanism, which are fitted onto the jump rope body.

[0016] S5: Connect the handles to both ends of the jump rope body;

[0017] S6: Packaging and storage.

[0018] By incorporating a weight-bearing mechanism located in the center of the jump rope body and symmetrically opposite to the adjustment mechanism, the weight-bearing mechanism can be adjusted to balance the center of gravity of the jump rope and balance the weight on both sides. Furthermore, based on the connection structure of the weight-bearing mechanism, its position can be adjusted according to the overall length of the jump rope body, reducing the difficulty of disassembly and installation.

[0019] As described above, a manufacturing process for a jump rope includes a jump rope body, with handles connected to both ends of the jump rope body. The jump rope body also includes an adjustment mechanism and two weight-bearing mechanisms, located at the center of the jump rope body and symmetrically opposite to the adjustment mechanism, respectively. The adjustment mechanism contains a traction mechanism. The adjustment mechanism includes a second external threaded sleeve and two semi-circular merging plates. The inner wall of the second external threaded sleeve is connected to the jump rope body via a connecting frame. The outer wall of the jump rope body is simultaneously fitted with a first clamping groove and a second clamping groove. Two semi-circular merging plates are respectively fixedly connected to their bottom ends with merging rings, and the two merging rings can be clamped in a first clamping groove and a second clamping groove. Limiting blocks are respectively provided at the same position in the first and second clamping grooves. Connecting pieces are simultaneously connected to the bottom ends of the two merging rings, and limiting grooves are provided at the contact points of the two merging rings, with the limiting blocks engaging within the limiting grooves. The outer walls of the two semi-circular merging plates are simultaneously provided with external threads, and a second internal threaded sleeve is engaged with the outer wall of the semi-circular merging plate through the external threads. The second internal threaded sleeve is simultaneously engaged with the outer wall of the second external threaded sleeve. The skipping rope manufacturing process provided by this invention has the technical effect of enabling significant length adjustments to the skipping rope, optimizing its multifunctionality and adaptability.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The skipping rope manufacturing process disclosed in this invention is mainly applied to the production of skipping ropes.

[0029] Reference Figures 1-3 A method for manufacturing a jump rope includes a jump rope body 2, with handles 1 connected to both ends of the jump rope body 2, and an adjustment mechanism 4 and two weight-bearing mechanisms 3 are provided on the jump rope body 2. The two weight-bearing mechanisms 3 are located at the center of the jump rope body 2 and at a position symmetrical to the adjustment mechanism 4, respectively. A traction mechanism 5 is provided inside the adjustment mechanism 4.

[0030] The adjustment mechanism 4 includes a second external threaded sleeve 401 and two semi-circular merging plates 406. The inner wall of the second external threaded sleeve 401 is connected to the jump rope body 2 through a connecting frame 411. The outer wall of the jump rope body 2 is simultaneously fixedly sleeved with a first clamping groove 404 and a second clamping groove 405. The bottom ends of the two semi-circular merging plates 406 are respectively fixedly connected with merging rings 407, and the two merging rings 407 can be clamped on the first clamping groove 404 and the second clamping groove 405. Limiting blocks 408 are respectively provided at the same position of the first clamping groove 404 and the second clamping groove 405. The bottom ends of the two merging rings 407 are simultaneously connected with connecting pieces 409, and the mating part of the two merging rings 407 is provided with a limiting groove 410. The limiting blocks 408 are engaged in the limiting groove 410.

[0031] The outer walls of the two semicircular merging plates 406 are simultaneously provided with external threads 403, and the outer walls of the semicircular merging plates 406 are engaged with a second internal thread sleeve 402 through the external threads 403. The second internal thread sleeve 402 is simultaneously engaged with the second external thread sleeve 401. In the adjusting mechanism 4, the semicircular merging plates 406 can be clamped on the first clamping groove 404 and the second clamping groove 405 respectively by merging rings 407, and the position of the merging ring 407 is limited by the limiting block 408 being engaged in the limiting groove 410. When the two semicircular merging plates 406 are merged and the external threads 403 are connected together, the second internal thread sleeve can be used to... 402. Establish a connection between the semi-circular merging plate 406 and the second external threaded sleeve 401. Since the second external threaded sleeve 401 is fixed on the jump rope body 2, and the semi-circular merging plate 406 is simultaneously limited and connected to the jump rope body 2, the excess jump rope body 2 can be inserted into the second external threaded sleeve 401. After establishing a connection through the second internal threaded sleeve 402, the jump rope body 2 can be shortened. At the same time, based on the first clamping groove 404 and the second clamping groove 405 set at different positions, the jump rope can be adjusted to three lengths, which are suitable for children, adults to use as single jump ropes, and for use as a large jump rope, thus optimizing the multi-functionality of the jump rope.

[0032] Reference Figure 2 and Figure 4 In a preferred embodiment, the traction mechanism 5 includes a damping collar 502, which is fixed to the inner wall of the second external threaded sleeve 401. An outer sleeve 505 is movably inserted inside the damping collar 502, and a second inner support rod 506 is movably fitted inside the outer sleeve 505.

[0033] Reference Figure 4In a preferred embodiment, one end of the second inner support rod 506 is fixedly connected to the first inner support rod 503, and one end of the first inner support rod 503 passes through the outer sleeve 505 and is connected to a circular support plate 501. The diameter of the first inner support rod 503 is smaller than that of the second inner support rod 506, and a spring 504 is provided between the second inner support rod 506 and the outer sleeve 505.

[0034] Reference Figure 4 In a preferred embodiment, the other end of the second inner support rod 506 is connected to a connecting rod 508 via a hinge seat 507. One end of the outer sleeve 505 is fixedly connected to a support frame 509. The middle section of the connecting rod 508 is movably connected to the support frame 509 via a connecting rod 510. The traction mechanism 5 can assist in the rope threading process. After the jump rope body 2 is partially threaded into the second external threaded sleeve 401, pressing the circular support plate 501 causes the spring 504 to contract, causing the second inner support rod 506 to push out. Under the limiting action of the connecting rod 510 and the hinge seat 507, the connecting rod 508 extends laterally and is inserted into the jump rope body 2 inside the second external threaded sleeve 401, serving as a hook. Thus, when the outer sleeve 505 is pulled outward along the damping collar 502, the jump rope body 2 can be pulled outward, thereby assisting in the folding of the jump rope body 2 and effectively reducing the difficulty of operation.

[0035] Reference Figure 5 In a preferred embodiment, the load-bearing mechanism 3 includes a connecting sleeve 307, and a first external threaded sleeve 308 is fixedly connected to one end of the connecting sleeve 307. A plurality of grippers 306 are fixedly connected to the outer wall of the other end of the connecting sleeve 307. The connecting sleeve 307 and the first external threaded sleeve 308 are simultaneously fixedly sleeved on the outside of the jump rope body 2.

[0036] Reference Figure 5 In a preferred embodiment, a limiting sleeve 304 is movably sleeved on the outside of the connecting sleeve 307, and a tapered groove 305 is provided inside the limiting sleeve 304, and a snap-fit ​​groove 303 is provided on one side of the inner wall of the limiting sleeve 304.

[0037] Reference Figure 5In a preferred embodiment, a snap-fit ​​strip 302 is movably snapped into the snap-fit ​​groove 303, and a first internal threaded sleeve 301 is fixedly connected to one outer wall of the snap-fit ​​strip 302. The first internal threaded sleeve 301 is movably engaged with the first external threaded sleeve 308. The load-bearing mechanism 3 is located at the middle position of the jump rope body 2 and at a symmetrical position with the adjustment mechanism 4, which can adjust the center of gravity of the jump rope and balance the load on both sides. At the same time, based on the connection structure of the load-bearing mechanism 3, as the first internal threaded sleeve 301 rotates, the limiting sleeve 304 and the first external threaded sleeve 308 gradually approach each other. Under the action of the conical groove 305, multiple grippers 306 gradually move inward to clamp until they are stably fixed to the outside of the jump rope body 2. Thus, the load-bearing mechanism 3 can be adjusted in position according to the overall length of the jump rope body 2, and the difficulty of disassembly and installation is reduced.

[0038] Reference Figure 6 In a preferred embodiment, the following specific steps are included:

[0039] S1: The jump rope is disassembled into handle 1, jump rope body 2, weight-bearing mechanism 3, adjustment mechanism 4 and traction mechanism 5.

[0040] S2: The handle 1 and the jump rope body 2 are injection molded and stretched;

[0041] S3: Fabricate all parts of the load-bearing mechanism 3, the adjusting mechanism 4, and the traction mechanism 5, and assemble them;

[0042] S4: Each jump rope body 2 is equipped with two load-bearing mechanisms 3 and one adjustment mechanism 4, which are fitted onto the jump rope body 2.

[0043] S5: Connect the handles 1 to both ends of the jump rope body 2;

[0044] S6: Packaging and storage.

[0045] Working principle: In the adjustment mechanism 4, the semi-circular merging plates 406 can be clamped onto the first clamping groove 404 and the second clamping groove 405 respectively by the merging ring 407, and the position of the merging ring 407 is limited by the limiting block 408 engaging in the limiting groove 410. When the two semi-circular merging plates 406 are merged and the external threads 403 are connected together, the connection between the semi-circular merging plates 406 and the second external threaded sleeve 401 can be established through the second internal threaded sleeve 402. Based on the fact that the second external threaded sleeve 401 is fixed on the jump rope body 2, and the semi-circular merging plates 406 are connected, the merging plates 406 are closed. The plate 406 is simultaneously positioned and connected to the jump rope body 2, allowing excess jump rope body 2 to be inserted into the second external threaded sleeve 401. After connection is established through the second internal threaded sleeve 402, the jump rope body 2 can be shortened. Furthermore, based on the different positions of the first clamping groove 404 and the second clamping groove 405, the jump rope can be adjusted to three lengths, suitable for children, adults, and large rope jumps, optimizing its versatility. Simultaneously, the traction mechanism 5 assists in the rope threading process, allowing partial threading of the jump rope body 2. After the second external threaded sleeve 401 is inserted, pressing the circular support plate 501 causes the spring 504 to contract, causing the second inner support rod 506 to push out. Under the limiting action of the connecting rod 510 and the hinge seat 507, the connecting rod 508 extends laterally and inserts into the jump rope body 2 inside the second external threaded sleeve 401, serving as a hook. Thus, when the outer sleeve 505 is pulled outward along the damping collar 502, the jump rope body 2 can be pulled outward, thereby assisting in the folding of the jump rope body 2 and effectively reducing the difficulty of operation. In addition, the load-bearing mechanism 3 is located on the jump rope body. The middle position of body 2 and the symmetrical position with the adjustment mechanism 4 can adjust the center of gravity of the jump rope and balance the load on both sides. At the same time, based on the connection structure of the load mechanism 3, as the first internal threaded sleeve 301 rotates, the limiting sleeve 304 and the first external threaded sleeve 308 gradually approach each other. Under the action of the conical groove 305, multiple grippers 306 gradually move inward to clamp until they are stably fixed to the outside of the jump rope body 2. Thus, the load mechanism 3 can be adjusted according to the overall length of the jump rope body 2, and the difficulty of disassembly and installation is reduced.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
