Description

Technical Field

[0001] The utility model belongs to the field of walking sticks, and particularly relates to a portable walking stick easy replacement system. Background Art

[0002] At present, outdoor walking stick products such as walking sticks and hiking poles can effectively assist outdoor walking, save physical strength and improve safety during outdoor mountain climbing, and are widely used by outdoor enthusiasts. In order to facilitate the storage and carrying of walking sticks, multi-section folding-connected walking sticks have been designed. For example, Chinese Patent Publication No.: CN220937045U discloses a foldable walking stick. Through the design of multi-section folding, the length size of the walking stick can be greatly shortened, which is convenient for temporary storage and placement. Inevitably, the walking stick may break due to reasons such as bumping and bending during use. Therefore, when disassembling, the pull rope needs to be separated from the rod tube, so as to replace the damaged rod tube. When the existing walking stick needs to replace the rod tube after breaking, the pull rope and the inside of the rod tube are fixedly designed, such as being fixedly bonded by glue. Therefore, the disassembly process is time-consuming and laborious, and it is easy to damage the rod tube, which is not conducive to quick replacement and repair. Summary of the Utility Model

Detailed implementation manners

[0026] The following further describes the present utility model in conjunction with the accompanying drawings and specific implementation manners.

[0027] Embodiment 1

[0028] As Figure 1 shown in Embodiment 1, a portable walking stick easy-to-replace system includes a top walking stick tube 11, a bottom walking stick tube 13, and at least one middle walking stick tube 12 located between the top walking stick tube 11 and the bottom walking stick tube 13. In this embodiment, there are four middle walking stick tubes 12 in total. As shown in conjunction with Figure 2 the figure, an elastic cord 3 is provided between the top walking stick tube 11 and the bottom walking stick tube 13. The elastic cord 3 passes through each middle walking stick tube 12 in sequence. Under the pulling force of the elastic cord 3, the top walking stick tube 11, the middle walking stick tube 12, and the bottom walking stick tube 13 form a coaxially arranged or nearly coaxially arranged walking stick body 1. In addition, a wrist strap 2 is provided on the top walking stick tube 11 to facilitate the user to pick up the walking stick.

[0029] As Figure 2 shown in, as shown in Figure 3, the bottom walking stick tube 13 is provided with a detachably connected lower positioning part 5. The lower positioning part 5 includes a lower connecting tube 52 and a lower connector 51. Among them, the lower connecting tube 52 is fixed to the bottom walking stick tube 13. Specific fixing means such as glue bonding and threaded connection can be selected according to the design and actual production process. As shown in conjunction with Figure 4 shown in, Figure 5 the figure, a threaded connection method is used to fix between the lower connector 51 and the lower connecting tube 52. Among them, the lower end of the lower connector 51 is provided with a threaded section 51b extending into the interior of the lower connecting tube 52, and the threaded section 51b is threadedly engaged and fixed with the inner wall of the lower connecting tube 52. The top of the lower connector 51 is provided with a lower cord end connection end 51d, and the lower cord end connection end 51d is provided with an inner hole 51c, so as to facilitate the elastic cord 3 to pass through. After the end of the elastic cord 3 passes through the inner hole 51c, a cord knot 31 is formed inside the lower connecting tube 52. In this way, when the self-tensile force of the elastic cord 3 acts on the lower positioning part 5, the cord knot 31 can act on the peripheral edge around the inner hole 51c. As shown in Figure 2 the figure, it drives the bottom walking stick tube 13 to approach the middle walking stick tube 12.

[0030] As Figure 4 shown, several working surfaces 51a parallel or nearly parallel to the thread axis of the thread section 51b are provided on the side surface of the lower connector 51. Through the working surface 51a, it is convenient to rotate the lower connector 51 to tighten or loosen it, and even the lower connector 51 can be turned without the aid of external tools. When the lower connector 51 is loosened and removed from the lower connecting pipe 52, the elastic cord 3 is disengaged from the connection with the bottom rod tube 13, thereby realizing the detachable connection between the elastic cord 3 and the bottom rod tube 13.

[0031] As Figure 6 、 Figure 7 shown, the upper positioning portion 4 includes an upper connecting seat 42 and an upper connector 41. Among them, the upper connecting seat 42 is fixed to the top rod tube 11, and specific fixing means such as glue bonding, screw connection, etc. can be selected according to the design and actual production process. The upper connecting seat 42 and the upper connector 41 are fixed by a screw connection method. Among them, the lower end of the upper connector 41 is provided with an upper connecting end 41b extending into the interior of the upper connecting seat 42, and the upper connecting end 41b is threadedly engaged and fixed with the inner wall of the upper connecting seat 42. The upper connector 41 is provided with an upper cord end connecting end 41d, and the upper cord end connecting end 41d has an annular structure with a through hole 41c. After the end of the elastic cord 3 passes through the through hole 41c of the upper cord end connecting end 41d, a knot 31 is formed, thereby realizing the fixation of the elastic cord 3 to the upper connector 41.

[0032] As Figure 6 、 Figure 7 shown, both the upper connecting seat 42 and the upper connector 41 are arranged at the upper end of the top rod tube 11. The top of the upper connecting seat 42 is provided with an upper connecting seat flange 42a that abuts against the upper end of the top rod tube 11, and the top of the upper connector 41 is provided with an upper connector flange 41a that abuts against the upper connecting seat flange 42a. In this way, both the upper connecting seat 42 and the upper connector 41 are axially positioned at the upper end of the top rod tube 11. When the self-tension of the elastic cord 3 acts on the upper positioning portion 4, the knot 31 can act on the upper connector 41, as Figure 2 shown, driving the top rod tube 11 to approach the middle rod tube 12. In addition, the wristband 3 can also be positioned through the upper connecting seat flange 42a and the upper connector flange 41a to ensure reliable connection of the wristband 3.

[0033] When the bottom rod tube 13 is damaged and needs to be disassembled, the bottom rod tube 13 and the adjacent middle rod tube 12 are pulled apart, and the elastic cord 3 is stretched under the action of the pulling force. At this time, the lower connector 51 can be rotated and screwed off from the top of the lower connecting pipe 52, and then the bottom rod tube 13 can be repaired and replaced. During replacement, only the lower connector 51 needs to be tightened at the top of the thread section 51b to realize the connection between the elastic cord 3 and the bottom rod tube 13.

[0034] When the top rod tube 11 is damaged and needs to be disassembled, the upper connector 41 can be directly unscrewed so that the upper connector 41 is separated from the upper connection base 42. At this time, the knot 31 of the elastic cord 3 on the upper connector 41 is untied, and the top rod tube 11 can be separated for maintenance and replacement. When replacing, the upper end of the elastic cord 3 is passed through the top rod tube 11 and a knot 31 is made and fixed through the through hole 41c of the upper connector 41, and then the upper connector 41 and the upper connection base 42 can be tightened and fixed.

[0035] When the middle rod tube 12 is damaged and needs to be disassembled, the relatively closer end can be selected from the top rod tube 11 and the bottom rod tube 13. After disassembling the top rod tube 11 or the bottom rod tube 13, the damaged middle rod tube 12 can be removed for replacement.

[0036] In addition, the top rod tube 11, the bottom rod tube 13 and the adjacent middle rod tube 12 are in threaded fit. The specific threaded fit method can refer to the technical solution disclosed in Chinese Patent Publication No. CN221179599U, that is, to ensure that the top rod tube 11 and the adjacent middle rod tube 12, the bottom rod tube 13 and the adjacent middle rod tube 12, and the middle rod tubes 12 are threadedly connected, so as to ensure the overall structural stability and support of the rod body 1 in use scenarios that require higher stability, such as long-distance downhill. When storing, after unscrewing the threads between the respective rod tubes, they are then pulled apart in sequence for folding storage, thereby realizing the quick opening and storage of the rod body.

[0037] Embodiment 2

[0038] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 8 shown, the lower rope end connection end 51d is provided with a lower hook body 6, and a hinged lower buckle rod 7 is provided at the opening of the lower hook body 6, and the lower end of the elastic cord 3 is hooked on the lower hook body 6. Before the lower end of the elastic cord 3 is hooked, it can be preset into a ring and knotted, so as to facilitate putting the lower end of the elastic cord 3 into the lower hook body 6 for hooking and positioning. The hinged connection between the lower buckle rod 7 and the lower hook body 6 enables the lower buckle rod 7 to rotate downward into the lower hook body 6 to facilitate the smooth placement of the elastic cord 3 into the lower hook body 6. In addition, a return spring can be provided between the lower buckle rod 7 and the lower hook body 6, so that the lower buckle rod 7 rotates and resets to close the opening of the lower hook body 6, thereby preventing the elastic cord 3 from accidentally loosening.

[0039] As Figure 9As shown, the upper rope end connection end 41d is provided with an upper hook body 8. An articulated upper buckle rod 9 is provided at the opening of the upper hook body 8. The upper end of the elastic rope is hung on the upper hook body 8. Before the upper end of the elastic rope 3 is hung, it can be preset into a loop and knotted, so as to facilitate putting the upper end of the elastic rope 3 into the upper hook body 8 for hanging and positioning. The hinge between the upper buckle rod 9 and the upper hook body 8 enables the upper buckle rod 9 to rotate into the upper hook body 8 to facilitate the smooth placement of the elastic rope 3 into the upper hook body 8. In addition, a return spring can be arranged between the upper buckle rod 9 and the upper hook body 8, so that the upper buckle rod 9 rotates and resets to close the opening of the upper hook body 8, thereby preventing the elastic rope 3 from accidentally loosening.
