Description

Technical Field

[0001] This utility model relates to the field of rope changing mechanism technology, and in particular to a rope changing mechanism for traction rope. Background Technology

[0002] With the continuous acceleration of urbanization, pet ownership has become an important choice for more and more families to enrich their lives and provide companionship. Daily dog ​​walking has also become an essential part of life for countless pet owners. In the current market, traditional pet leashes are still the choice of many users. These leashes mostly use ordinary nylon braided rope, cotton rope, or basic plastic rope as the core connecting components.

[0003] Currently, dogs often chew on their leashes during walks out of curiosity, teething, or excitement, especially energetic small and medium-sized dogs or puppies. They can easily bite cracks or even break the leash. Once the leash breaks, the entire leash loses its core function. Even if the handle, the buckle connecting to the pet collar, and other parts are completely intact, it cannot be used anymore. Users will have to buy a whole new leash, which easily leads to a waste of resources. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. Currently, dogs often chew on the leash during walks out of curiosity, teething, or excitement, especially energetic small and medium-sized dogs or puppies. They can easily bite cracks or even break the leash. Once the leash breaks, the entire leash loses its core function. Even if the handle, the buckle connecting the pet collar, and other parts are completely intact, it cannot be used. Users can only buy a new leash, which easily leads to a waste of resources. Therefore, a leash replacement mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rope changing mechanism for a traction rope includes a handheld housing with a rope loop assembly. The rope loop assembly includes a rope loop fixing housing, a rope loop body, and a fixing disc. The handheld housing has an opening for mounting the rope loop fixing housing. A limiting component is provided on the handheld housing. The limiting component includes an arc-shaped strip connected to the handheld housing via a first spring. An arc-shaped protrusion is fixedly connected to the arc-shaped strip. The rope loop fixing housing has an arc-shaped opening for connecting the arc-shaped strip. A T-shaped post is fixedly connected to the outer shell of the rope loop. A clamping component is provided on the T-shaped post. The T-shaped post and the fixing disc are threaded together. A circular hole for connecting the T-shaped post is provided on the rope loop body. A rope outlet hole is provided on the outer shell of the rope loop.

[0006] Preferably, a plurality of positioning cylinders are fixedly connected inside the handheld shell, and a plurality of positioning strips are fixedly connected to the rope loop fixing shell, each of the positioning strips being slidably connected to the corresponding positioning cylinder.

[0007] Preferably, an iron sheet is fixedly connected to one end of the arc-shaped strip, and a magnet is fixedly connected to the inner wall of one side of the arc-shaped opening.

[0008] Preferably, the clamping assembly includes a clamping ring sleeved on the outside of the T-shaped post, and a second spring is fixedly connected to the clamping ring, the second spring being fixedly connected to the T-shaped post.

[0009] Preferably, a wear-resistant sheet is fixedly connected to the lower surface of the clamping ring, and the wear-resistant sheet is made of polytetrafluoroethylene.

[0010] Preferably, the inner wall of the circular hole has multiple slots arranged in a ring array, the multiple slots are connected by annular grooves, and the outer surface of the T-shaped column is rotatably connected with multiple ball bearings.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This solution addresses the problem of resource waste associated with traditional leashes. Traditional leashes require complete replacement when the rope breaks, while this system allows for the replacement of the rope loop itself. Intact parts such as the handheld casing, rope loop fixing casing, and fixing disc can be reused, avoiding the problem of "complete disposal due to partial rope damage." This significantly reduces resource waste and lowers pet ownership costs.

[0012] The rope changing operation is convenient and efficient. Through the limit component's "press release + magnetic assisted positioning", the clamping component's "spring elastic clamping + threaded fixing double protection", and the cooperation of the T-shaped column ball and the grooved and annular groove of the rope loop body, rope changing does not require complicated tools. The steps are simple and ordinary users can complete it quickly, improving the convenience of use.

[0013] The rope is securely fixed with minimal wear. The clamping ring provides continuous clamping force through the first spring, and together with the threaded limit of the fixing plate, it can firmly fix the rope body to the T-shaped post, preventing the rope from loosening or slipping when walking the pet. The polytetrafluoroethylene wear-resistant sheet on the lower surface of the clamping ring uses its low coefficient of friction to reduce frictional wear between the rope and the wear-resistant sheet, extending the service life of the rope body.

[0014] With strong structural stability and safety, the rope loop fixing shell is precisely positioned through the sliding cooperation of the positioning strip and the positioning cylinder. Combined with the arc-shaped protrusion of the limiting component and the magnetic double limiting, it ensures that the rope loop fixing shell will not shake or fall off inside the handheld shell during use, ensuring the stability and safety of the leash process and preventing the pet from losing control due to structural loosening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0019] Reference Figures 1-5A rope changing mechanism for a traction rope includes a handheld housing 1, on which a rope loop assembly is provided. The rope loop assembly includes a rope loop fixing housing 7, a rope loop body 19, and a fixing plate 18. The rope loop body 19 has an I-shaped cross-section, and a rope is wound around its outer side. An irregular opening 2 is provided on the handheld housing 1 for mounting the rope loop fixing housing 7. A limiting assembly is provided on the handheld housing 1, which includes an arc-shaped strip 3 connected to the handheld housing 1 by a first spring 4. The two ends of the first spring 4 are respectively connected to the arc-shaped strip 3 and the handheld housing. 1. Fixed connection: An arc-shaped protrusion 5 is fixedly connected to the arc-shaped strip 3. An arc-shaped opening 9 for connecting the arc-shaped strip 3 is opened on the rope ring fixing shell 7. A T-shaped post 12 is fixedly connected to the rope ring fixing shell 7. A clamping component is provided on the T-shaped post 12. The T-shaped post 12 and the fixing plate 18 are threadedly connected. A round hole for connecting the T-shaped post 12 is opened on the rope ring fixing shell 7. A rope outlet hole 11 is opened on the rope ring fixing shell 7. The rope and the rope body using the rope ring body 19 pass through the rope outlet hole 11 of the rope ring fixing shell 7 and are connected to the pet collar and other components for use in pet walking and leashing.

[0020] Multiple positioning cylinders 6 are fixedly connected inside the handheld shell 1, and multiple positioning strips 8 are fixedly connected to the rope loop fixing shell 7. Each positioning strip 8 is slidably connected to the corresponding positioning cylinder 6. During assembly, the positioning strip 8 slides along the positioning cylinder 6 to achieve precise positioning of the rope loop fixing shell 7 inside the handheld shell 1, preventing displacement during use. One end of the arc-shaped strip 3 is fixedly connected to an iron plate, and one side of the inner wall of the arc-shaped opening 9 is fixedly connected to a magnet 10. When the rope loop fixing shell 7 is installed in place, the external force applied to the arc-shaped protrusion 5 is removed. Under the elastic force of the first spring 4, one end of the arc-shaped strip 3 slides into the arc-shaped opening 9, and the iron plate of the arc-shaped strip 3 is attracted to the magnet 10, enhancing the limiting stability and preventing the rope loop fixing shell 7 from accidentally detaching.

[0021] The clamping assembly includes a clamping ring 13 sleeved on the outside of the T-shaped post 12. A second spring 14 is fixedly connected to the clamping ring 13. The second spring 14 and the T-shaped post 12 are fixedly connected. The second spring 14 enables the clamping ring 13 to have elastic clamping capability. A wear-resistant plate is fixedly connected to the lower surface of the clamping ring 13. The wear-resistant plate is in contact with the upper surface of the rope loop body 19. The wear-resistant plate is made of polytetrafluoroethylene. The low friction and wear-resistant properties of the wear-resistant plate reduce frictional loss with the rope loop body 19. The inner wall of the circular hole has multiple slots 17 arranged in a ring array. The multiple slots 17 are connected by an annular groove 16. Multiple balls 15 are rotatably connected to the outer surface of the T-shaped post 12. During assembly, each ball 15 rolls along the corresponding slot 17 until all balls 15 have moved into the annular groove 16.

[0022] In this invention, during assembly, the circular hole of the rope loop body 19 is first aligned with the T-shaped post 12. The ball bearings 15 on the T-shaped post 12 engage with the slots 17 and annular grooves 16 on the inner wall of the circular hole of the rope loop body 19, quickly fitting the rope loop body 19 onto the outer side of the T-shaped post 12, with each ball bearing 15 fitting snugly against the inner wall of the annular groove 16. Then, the fixing disc 18 is tightened to connect with the T-shaped post 12 via a thread, initially fixing the rope loop body 19 axially. Next, under the elastic force of the second spring 14, the clamping ring 13... The PTFE wear-resistant sheet applies downward pressure to the rope ring body 19, achieving a tight axial fixation of the rope ring body 19 and effectively preventing vertical movement of the rope ring body 19. Then, the rope ring fixing shell 7, with the rope ring assembly assembled, is inserted into the opening 2 of the handheld shell 1 through the sliding cooperation of the positioning strip 8 and the positioning cylinder 6. At this time, under the elastic force of the first spring 4, the arc-shaped strip 3 causes the arc-shaped protrusion 5 to be inserted into the arc-shaped opening 9, and the iron sheet is attracted to the magnet 10, completing the limiting fixation of the rope ring fixing shell 7 and the handheld shell 1. The rope changing mechanism is then assembled.

[0023] During the rope replacement process, when the rope needs to be replaced due to the dog chewing on it, press the arc-shaped bar 3 to compress the first spring 4, causing the arc-shaped protrusion 5 to disengage from the arc-shaped opening 9. At the same time, the iron plate separates from the magnet 10. Then, remove the rope loop fixing shell 7, loosen the fixing plate 18, compress the second spring 14, and lift the clamping ring 13 to remove the old rope loop body 19. After that, install the new rope loop body 19 according to the assembly steps, and put the rope loop fixing shell 7 back into the handheld shell 1 to complete the rope replacement.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
