Description

Technical Field

[0001] This application relates to the technical field of jump ropes, and in particular to a jump rope handle. Background Technology

[0002] As a common sports equipment, jump ropes are widely used in physical exercise, fitness training and competitive sports. As an important part of jump ropes, the structural design of jump rope handles directly affects the ease of use, durability and manufacturing cost.

[0003] Most jump rope handles on the market today use a split structure, typically consisting of a first shell and a second shell, which are connected by a male and female buckle. While this structure can achieve basic functions, its manufacturing process requires separate molds for the first and second shells, resulting in high production costs, complicated procedures, and low assembly efficiency.

[0004] Because the first and second shells are structurally asymmetrical, they cannot share a mold, resulting in high mold development costs and long production cycles. In addition, the split structure is prone to problems such as inaccurate positioning and weak connection during assembly, which reduces the overall strength of the product and the user experience. Summary of the Invention

[0005] To reduce the cost of manufacturing jump rope handles, a jump rope handle is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A jump rope handle includes two identical handle inner shells, which are detachably connected to each other to form the inner core of the jump rope handle. Each of the inner shells of a single handle is integrally formed with a connecting base plate on both sides. A hook is integrally formed on one side of the connecting base plate of the single inner shell of a single handle, and a locking groove is formed on the other side of the connecting base plate of the single inner shell of a single handle. The hook on one inner shell of a single handle and the locking groove on the other inner shell of a single handle engage to achieve the connection of the two inner shells of a single handle.

[0007] By adopting the above technical solution, since the inner shells of the two handles have the same structure, only one mold needs to be developed for mass production. Compared with the existing technology that requires two molds to produce asymmetrical shells, this directly saves mold costs, reduces production management procedures, and improves production efficiency. In addition, the detachable connection is achieved through the cooperation of hooks and locking grooves, which simplifies the assembly process, improves the consistency and reliability of assembly, and avoids problems such as inaccurate positioning and loose connection caused by differences in parts in the traditional split structure. This improves the overall structural strength of the product and the user experience.

[0008] Preferably, the two inner shells of the handles are further provided with a guide mechanism, which includes a guide rod and a guide sleeve. The guide rod and the guide sleeve are symmetrically arranged along their own axes, and one of the guide rods is inserted into the other guide sleeve to achieve the guiding and positioning of the two inner shells of the handles.

[0009] By adopting the above technical solution, a guiding mechanism consisting of a guide rod and a guide sleeve is added, which plays a role in pre-positioning and guiding when the inner shells of the two handles are connected. It can effectively prevent the hook and the engagement groove from being misaligned or skewed during the engagement process, ensuring a smooth and accurate connection process, further improving the precision and efficiency of assembly, and reducing the scrap rate caused by assembly errors.

[0010] Preferably, a sealing rib is integrally formed on the inner edge of one side of a single handle inner shell, and a sealing groove is formed on the inner edge of the other side of a single handle inner shell, and the sealing rib of one handle inner shell is inserted into the sealing groove of the other handle inner shell to achieve a tight connection between the outer walls of the two handle inner shells.

[0011] By adopting the above technical solution, and through the interlocking of sealing ribs and sealing grooves on the inner edge, a tight connection is achieved at the seam between the inner and outer walls of the two handles, improving the visual aesthetics and overall appearance of the inner core, forming a physical barrier that effectively prevents dust, sweat and other foreign objects from entering the handle from the seam, protecting the internal structure from pollution and corrosion, thereby extending the product's service life.

[0012] Preferably, it further includes a first outer shell and a second outer shell sleeved on the outside of the two inner shells of the handle. The first outer shell and the second outer shell are detachably connected. The inner walls of the first outer shell and the second outer shell are integrally formed with reinforcing ribs, and the reinforcing ribs abut against and cooperate with the outer walls of the inner shells of the handles.

[0013] By adopting the above technical solution, the first and second outer shells are detachably connected and wrapped around the outer core, forming a dual protection structure that enhances the handle's impact and wear resistance. The reinforcing ribs on the inner wall improve the rigidity and deformation resistance of the outer shell itself.

[0014] Preferably, the inner walls of the first outer shell and the second outer shell are respectively provided with positioning members, and the outer walls of the two inner shells of the handle are respectively provided with positioning grooves for the positioning members to be inserted.

[0015] By adopting the above technical solution, the insertion and cooperation of the positioning component and the positioning groove provides a clear and rapid radial and axial positioning reference for the installation of the first and second outer shells. This allows workers to quickly and accurately fit the outer shells into the correct positions during assembly. At the same time, it can effectively limit the movement in the direction perpendicular to the axis of the inner shell of the handle, restricting all unintended relative movements between the inner shell and the outer shell of the handle.

[0016] Preferably, the first outer shell is integrally formed with a buckle, and the second outer shell is integrally formed with a hook that engages with the buckle.

[0017] By adopting the above technical solution, the buckle and hook connection method can be quickly disassembled and assembled without any tools, which greatly facilitates users' daily maintenance, cleaning or replacement of the jump rope.

[0018] Preferably, the inner wall of the first housing is integrally formed with a first connecting tube, and the inner wall of the second housing is integrally formed with a second connecting tube. The second connecting tube is inserted into the first connecting tube, and the first connecting tube and the second connecting tube are connected by screw threads.

[0019] By adopting the above technical solution, the insertion of the second connecting tube into the first connecting tube firstly serves as a guide and pre-positioning mechanism, simplifying the screw-in process. Subsequently, the tightening of the screw provides a strong locking force, ensuring that the first and second outer shells will not loosen or detach during high-intensity, high-frequency rope skipping exercises. This is particularly suitable for professional competitions or high-intensity training scenarios, greatly improving the reliability and safety of the product.

[0020] Preferably, the first outer shell and the second outer shell are respectively provided with limiting grooves. When the first outer shell and the second outer shell are sleeved on the outer wall of the handle inner shell, the ends of the two handle inner shells are embedded in the limiting grooves.

[0021] By adopting the above technical solution, the inner and outer shells of the handle are precisely positioned and firmly limited in the axial direction through the embedded fit of the limiting ring groove and the inner shell end, and the end face of the outer shell and the end of the inner core are kept flat, which improves the appearance quality of the product and the comfort when holding it.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Two identical handle inner shells are used to form the inner core, which means that only one mold needs to be developed to complete the mass production of the core component. This changes the traditional solution that requires two molds to manufacture asymmetrical shells, saving mold development costs, manufacturing costs and warehousing management costs. 2. The first and second outer shells are wrapped around the outer shell of the handle by hooks and buckles, forming a double protection structure that enhances the handle's impact and wear resistance. The reinforcing ribs on the inner wall improve the rigidity and deformation resistance of the outer shell itself. At the same time, the positioning parts and positioning grooves are engaged to effectively limit the movement in the direction perpendicular to the axis of the handle's inner shell, restricting all unintended relative movements between the inner and outer shells of the handle.

[0025] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0026] As attached Figure 1 and attached Figure 2 As shown, a jump rope handle includes two identical handle inner shells 1 and a guide mechanism 2. The handle inner shells 1 are made of plastic and are integrally molded by injection molding. The two handle inner shells 1 are detachably connected to form the inner core of the jump rope handle.

[0027] The inner shell 1 of the handle includes a cord binding part 11 and a grip part 12. The cord binding part 11 is used to bind the cord, and the grip part 12 is used by the user to grip. Each inner shell 1 of the handle includes two integrally molded connecting base plates 13. The connecting base plates 13 are located inside the cord binding part 11. The two connecting base plates 13 are symmetrically arranged along the axis of the inner shell 1 of the handle. The two connecting base plates 13 are respectively located on the inner walls of the two sides of the inner shell 1 of the handle. The end of the connecting base plate 13 on one inner shell 1 abuts against the end of the connecting base plate 13 on the other inner shell 1 of the handle.

[0028] As attached Figure 2 and attached Figure 3 As shown, a hook 131 is integrally molded on the connecting base plate 13 on one side of the single handle inner shell 1. The hook 131 is trapezoidal in shape, which facilitates guidance and positioning during engagement. A locking groove 132 is opened on the connecting base plate 13 on the other side of the single handle inner shell 1. The shape of the locking groove 132 is adapted to the shape of the hook 131. When the hook 131 on one handle inner shell 1 is engaged into the locking groove 132 of the other handle inner shell 1 through elastic deformation, the connection of the two handle inner shells 1 is realized.

[0029] A sealing rib 14 is integrally injection molded on one side of the inner edge of a single handle inner shell 1. The sealing rib 14 extends from the cord binding part 11 to the grip part 12. A sealing groove 15 is integrally injection molded on the other side of the inner edge of a single handle inner shell 1. The sealing groove 15 extends from the cord binding part 11 to the grip part 12. The protruding shape of the sealing rib 14 is adapted to the shape of the sealing groove 15. When the sealing rib 14 of one handle inner shell 1 is inserted into the sealing groove 15 of another handle inner shell 1, a tight connection is achieved between the outer walls of the two handle inner shells 1, enhancing the stability and sealing of the connection.

[0030] The guiding mechanism 2 includes a guide rod 21 and a guide sleeve 22. Both the guide rod 21 and the guide sleeve 22 are located inside the cord binding part 11. The guide rod 21 and the guide sleeve 22 are symmetrically arranged along the axis of the inner shell 1 of the handle. The guide rod 21 and the guide sleeve 22 of a single inner shell 1 are located on the inner walls on both sides of the inner shell 1 of the handle. The guide rod 21 is cylindrical in shape, and the guide sleeve 22 is tubular in shape, with its inner diameter matching the outer diameter of the guide rod 21. When one inner shell 1 of the handle is connected to another inner shell 1 of the handle, the guide rod 21 of one inner shell 1 will be inserted into the guide sleeve 22 of the other inner shell 1, realizing the guiding positioning when the two inner shells 1 are connected, ensuring the accuracy and consistency of the two inner shells 1 during the connection process, and avoiding the problem of inaccurate positioning.

[0031] As attached Figure 4 and attached Figure 5 As shown, a first outer shell 3 and a second outer shell 4 are also fitted on the outer wall of the grip part 12. The first outer shell 3 and the second outer shell 4 are detachably connected to the outer wall of the inner shell 1 of the handle. The first outer shell 3 and the second outer shell 4 are both semi-tubular in shape. The inner walls of the first outer shell 3 and the second outer shell 4 are integrally injection molded with reinforcing ribs 5. The reinforcing ribs 5 are semi-ring shaped, and the inner wall of the reinforcing ribs 5 is abutted against the outer wall of the inner shell 1 of the handle. The function of the reinforcing ribs 5 is to enhance the strength and rigidity of the inner shell 1 of the handle and prevent the outer shell from deforming during use.

[0032] The first outer shell 3 has a buckle 31 integrally injection molded on the side facing the second outer shell 4. The buckle 31 is shaped like an elastic hook. There are two buckles 31 on the inner walls of both sides of the first outer shell 3. The second outer shell 4 has a locking block 41 integrally injection molded on the side facing the first outer shell 3. There are two locking blocks 41 on the inner walls of both sides of the second outer shell 4. The first outer shell 3 and the second outer shell 4 are connected by the buckle 31 and the locking block 41. The locking method of the buckle 31 and the locking block 41 can be quickly disassembled and assembled without any tools, which greatly facilitates the user's daily maintenance, cleaning or replacement of the rope.

[0033] Two first connecting tubes 32 are integrally molded on the inner wall of the first outer shell 3 facing the second outer shell 4. Two second connecting tubes 42 are integrally molded on the inner wall of the second outer shell 4 facing the first outer shell 3. The inner diameter of the first connecting tube 32 is matched with the outer diameter of the second connecting tube 42. Both the inner walls of the first connecting tube 32 and the second connecting tube 42 are threaded. When the first outer shell 3 and the second outer shell 4 are connected, the second connecting tube 42 is inserted into the first connecting tube 32. Then, screws are passed through the first connecting tube 32 and threadedly connected to the second connecting tube 42, which further strengthens the connection between the first outer shell 3 and the second outer shell 4.

[0034] Positioning members 6 are integrally injection molded on the inner walls of the opposite side of the first outer shell 3 and the second outer shell 4. The positioning members 6 are columnar in shape, and the two handle inner shells 1 have positioning grooves 16 on the outer walls of the grip portion 12 for the positioning members 6 to be inserted. When the first outer shell 3 and the second outer shell 4 are fitted onto the outside of the handle inner shell 1, the positioning member 6 of the first outer shell 3 is inserted into the positioning groove 16 of one handle inner shell 1, and the positioning member 6 of the second outer shell 4 is inserted into the positioning groove 16 of the other handle inner shell 1. In this way, the handle inner shell 1 is effectively limited in the direction perpendicular to the axis of the handle inner shell 1, restricting all unintended relative movements between the handle inner shell 1 and the first outer shell 3 and the second outer shell 4.

[0035] Limiting grooves 7 are respectively opened on the inner walls of the first outer shell 3 and the second outer shell 4 facing the handle inner shell 1. The cross section of the limiting groove 7 in the axial direction of the handle inner shell 1 is semi-annular. When the first outer shell 3 and the second outer shell 4 are sleeved on the outside of the handle inner shell 1, the limiting grooves 7 on the first outer shell 3 and the second outer shell 4 are combined to form an annular groove. The ends of the two handle inner shells 1 located at the grip part 12 are both embedded in the limiting annular groove, realizing the precise positioning and firm limiting of the handle inner shell 1 with the first outer shell 3 and the second outer shell 4 in the axial direction.

[0036] The implementation principle of this embodiment is as follows: Design two identical handle inner shells 1. Each handle inner shell 1 has a hook 131 and a locking groove 132 integrated on both sides. The two handle inner shells 1 can be connected to form a complete handle inner core by the interlocking of the hook 131 and the locking groove 132. The two handle inner shells 1 can be injection molded from the same mold, avoiding the cost of developing two sets of molds to produce asymmetrical parts in the traditional solution. After the two inner shells 1 of the handle are assembled, the outer shell half is used to achieve reinforcement, limiting and gripping functions. The first shell 3 and the second shell 4 are detachably connected by the cooperation of the buckle 31 and the locking block 41. At the same time, the limiting parts on the inner walls of the first shell 3 and the second shell 4 cooperate with the limiting groove 7 on the outer wall of the inner shell 1 of the handle to restrict the movement of the inner shell 1 of the handle in the axial direction.

[0037] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
