Description

Technical Field

[0001] This application relates to the field of outdoor product technology, specifically to a pole structure and a trekking pole. Background Technology

[0002] Trekking poles are a common auxiliary tool used in outdoor mountaineering and hiking. They help hikers maintain better balance, reduce leg strain, conserve energy, and can also prevent falls and injuries to some extent. To accommodate people of different heights and meet the length requirements of different terrains, trekking poles typically have an adjustable shaft structure. The shaft structure of a trekking pole is generally composed of multiple interlocking shafts. When adjusting the length, adjacent shafts can slide relative to each other to extend or retract to the target length and then lock in place.

[0003] However, during the adjustment process, it is easy for two adjacent poles to be over-adjusted, that is, the two poles that are interlocked are stretched too far. If the two poles are stretched too far, they will separate from each other, which will affect the normal use of the trekking pole. The hiker will need to manually reassemble the two separated poles, which will greatly affect the user experience of the trekking pole. Summary of the Invention

[0004] One objective of this application is to provide a rod structure capable of limiting excessive adjustment of two rods.

[0005] Another objective of this application is to provide a hiking stick.

[0006] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a rod structure, including an upper rod, a lower rod, and at least one secondary rod, wherein the upper rod, the secondary rod, and the lower rod are sequentially and telescopically sleeved together, and a pull rope is also inserted into the upper rod, the secondary rod, and the lower rod. The pull rope is provided with a limiting part, and the secondary rod is provided with a mating part. The mating part has a limiting cavity. One end of the pull rope is connected to the upper rod, and the other end of the pull rope passes through the mating part and the secondary rod and is connected to the lower rod, so that the limiting part is accommodated in the limiting cavity. The mating part is provided with a locking clamp, which is adapted to axially limit the limiting part in the limiting cavity.

[0007] As a preferred embodiment, the mating part includes a main body and a first locking block that is independent of and separable from the main body. The first locking block is disposed on the main body and the limiting cavity is formed between the two. The locking clamp is disposed on the main body and can lock the first locking block on the main body.

[0008] As another preferred embodiment, the limiting cavity includes a first limiting surface and a second limiting surface disposed opposite to each other in the axial direction of the rod body, the main body defines the first limiting surface, the first locking block defines the second limiting surface, the limiting part is located between the first limiting surface and the second limiting surface, and the first limiting surface and the second limiting surface are adapted to limit the axial displacement of the limiting part.

[0009] Further preferably, the main body is columnar, and the locking member includes a plurality of locking walls disposed on the main body and arranged circumferentially on the main body. The plurality of locking walls are adapted to enclose and form a locking cavity. A retaining member is disposed on the locking wall, and the retaining member is adapted to abut against and cooperate with the first locking block to lock the first locking block in the locking cavity.

[0010] Furthermore, the abutting member abuts against the outer peripheral wall of the first locking block to lock the first locking block in the locking cavity;

[0011] And / or, the abutment abuts against the bottom end face of the first locking block to confine the first locking block within the locking cavity.

[0012] Furthermore, the main body includes an inner sleeve and a main end wall disposed on the inner sleeve. The locking wall is disposed on the inner sleeve. The first locking block is locked in the locking cavity and abuts against the main end wall. The first locking block is provided with a first groove. The main end wall and the first groove surround and define the limiting cavity. The main end wall defines the first limiting surface of the limiting cavity, and the first groove defines the second limiting surface of the limiting cavity. The first limiting surface and the second limiting surface limit the axial displacement of the limiting portion.

[0013] Furthermore, the main body includes an inner sleeve and a second locking block disposed on the inner sleeve. The locking clamp wall is disposed on the inner sleeve. The first locking block is locked in the locking cavity and abuts against the second locking block. The second locking block is provided with a second groove, and the first locking block is provided with a first groove. The second groove and the first groove surround and define the limiting cavity. The second groove defines the first limiting surface of the limiting cavity, and the first groove defines the second limiting surface of the limiting cavity. The first limiting surface and the second limiting surface restrict the axial displacement of the limiting part.

[0014] Furthermore, the outer diameter of the locking member is smaller than the outer diameter of the main body. A transition boss is provided between the main body and the locking member.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] The two ends of the pull rope are connected to the upper and lower rods respectively. The main body of the pull rope is connected to the secondary rod through the cooperation of the limiting part and the mating part. The mating part is axially limited inside the secondary rod. Since the length of the pull rope is fixed and the pull rope is stretched to its maximum length when the secondary rod is in the maximum extension position, the pull rope is suitable for limiting the further extension of the secondary rod in the maximum extension position, thereby avoiding the secondary rod from being overstretched and separating from the upper rod. Similarly, the pull rope can also limit the further extension of the lower rod in the maximum extension position, thereby avoiding the lower rod from being overstretched and separating from the secondary rod.

Detailed Implementation

[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0033] like Figure 1As shown in the figure, this application provides a trekking pole, which includes a handle structure, a tip structure, and a shaft structure.

[0034] The rod structure includes an upper rod 100, a lower rod 200, and a secondary rod 300. The secondary rod 300 is telescopically connected to the upper rod 100, and the lower rod 200 is telescopically connected to the secondary rod 300. Thus, the secondary rod 300 can slide axially relative to the upper rod 100, and the lower rod 200 can slide axially relative to the secondary rod 300. The connection points between the upper rod 100 and the secondary rod 300, and between the secondary rod 300 and the lower rod 200, are all equipped with... A locking mechanism 600 is provided. The locking mechanism 600 can be implemented as a common external locking structure or an internal locking structure. The locking mechanism 600 is suitable for locking or unlocking the secondary rod 300 and the lower rod 200. When the locking mechanism 600 locks the secondary rod 300 and the lower rod 200, the secondary rod 300 and the lower rod 200 are restricted from telescopic sliding. When the locking mechanism 600 unlocks the secondary rod 300 and the lower rod 200, the secondary rod 300 and the lower rod 200 are allowed to telescopic slide.

[0035] It is worth mentioning that the number of secondary rods 300 in the rod structure is not limited to one. The rod structure may include two or more secondary rods 300. Multiple secondary rods 300 are arranged sequentially along the axial direction and adjacent secondary rods 300 are telescopically connected. The two secondary rods 300 located at the first and last ends are telescopically connected to the upper rod 100 and the lower rod 200, respectively.

[0036] like Figure 2 As shown, each rod has a pull rope 400 inside. The two ends of the pull rope 400 are connected to the upper rod 100 and the lower rod 200, respectively. The pull rope 400 has a limiting part 410. The number of limiting parts 410 is the same as the number of secondary rods 300. The end of the secondary rod 300 is provided with a mating part 500 for cooperating with the limiting part 410. The mating part 500 has a limiting cavity 550, and the limiting part 410 is housed in the limiting cavity 550. Since the maximum length of the pull rope 400 is fixed and the pull rope 400 is stretched to its maximum length when the secondary rod 300 is in the maximum extension position, the pull rope 400 is adapted to limit the secondary rod 300 in the maximum extension position from further extending outward, thereby preventing the secondary rod 300 from over-extending and causing it to separate from the upper rod 100; similarly, the pull rope 400 is also adapted to limit the lower rod 200 in the maximum extension position from further extending outward, thereby preventing the lower rod 200 from over-extending and causing it to separate from the secondary rod 300.

[0037] In the embodiments of this application, the pull rope 400 is connected to the upper rod 100 and to the lower rod 200 using a knot-locking method. Specifically, the two ends of the pull rope 400 are wound together to form knots, and the upper rod 100 and lower rod 200 have through holes with a diameter smaller than the knot size. The through holes are suitable for restricting the knots from passing through so that the two ends of the pull rope 400 are connected to the upper rod 100 and lower rod 200 respectively. In practical applications, in addition to the knot-locking method, the pull rope 400 can also be connected to the upper rod 100 and lower rod 200 by means of adhesive bonding, fastening, etc.

[0038] Furthermore, the mating part 500 includes a main body 510, a locking clamp 520, and a first locking block 530 that is independent of and separable from the main body 510.

[0039] like Figure 3 As shown, the main body 510 and the locking clamp 520 are integrally formed and connected. Both the main body 510 and the locking clamp 520 are columnar. The outer diameter of the locking clamp 520 is smaller than the outer diameter of the main body 510, so that a transition boss 540 is formed between the main body 510 and the locking clamp 520. The locking clamp 520 is suitable for being embedded in the interior of the secondary rod 300, and the transition boss 540 is suitable for abutting against the end face of the secondary rod 300 to install the mating part 500 at the end of the secondary rod 300. The first locking block 530 is locked onto the main body 510 by the locking clamp 520. The first locking block 530 and the main body 510 are... The aforementioned limiting cavity 550 is formed, and the limiting cavity 550 includes a first limiting surface 551 and a second limiting surface 552 disposed opposite each other in the axial direction. The main body 510 defines the first limiting surface 551, and the first locking block 530 defines the second limiting surface 552. The limiting part 410 is received in the limiting cavity 550 and located between the first limiting surface 551 and the second limiting surface 552. The first limiting surface 551 and the second limiting surface 552 are adapted to hold the limiting part 410 in the limiting cavity 550 and to limit the axial displacement of the limiting part 410. When the secondary rod 300 is in the maximum extended position, the pull rope 400 is stretched to its maximum length, and the limiting part 410 abuts against the first limiting surface 551, thereby limiting the secondary rod 300 from extending further outward.

[0040] like Figure 4As shown, the main body 510 is provided with a guide slope 560 and an axial cut 570. Based on the structure of the guide slope 560 and the axial cut 570, the main body 510 can guide the secondary rod 300 to be embedded into the interior of the upper rod 100. This avoids direct friction between the secondary rod 300 and the upper rod 100 while improving the smoothness and stability of the secondary rod 300 during axial extension and retraction relative to the upper rod 100, and reducing wobbling and loosening between the upper rod 100 and the secondary rod 300. Existing trekking poles typically have guide plugs at the ends of the poles to improve the smoothness and stability during extension and retraction. In other words, the mating part 500 in this embodiment is equivalent to the guide plug in existing trekking poles. Compared with the pole structure in existing trekking poles, the pole structure in this embodiment does not add any extra parts or extra weight, and therefore does not increase the burden on the user.

[0041] like Figure 3-6 As shown, the main body 510 includes an inner bushing 511 and a main end wall 512 disposed on the inner bushing 511. The locking member 520 includes a plurality of locking walls 521 extending axially and abutting members 522 disposed at the ends of the locking walls 521. In this embodiment, the locking member 520 includes four locking walls 521 and abutting members 522 disposed at the ends of the locking walls 521. The four locking walls 521 are circumferentially arranged around the bottom of the inner bushing 511. The four locking walls 521 enclose and define a locking cavity. The abutting members 522 are adapted to abut against and cooperate with the first locking block 530 to lock the first locking block 530 in the locking cavity. A locking groove 523 is also formed between two adjacent locking walls 521. A first locking rib 531 adapted to the locking groove 523 is provided on the outer peripheral wall of the first locking block 530. When the first locking block 530 is mounted on the main body 510, the top surface of the first locking block 530 abuts against the main end wall 512, the locking groove 523 receives the first locking rib 531 of the first locking block 530, and the abutting member 522 abuts against the outer peripheral wall of the first locking block 530, so that the first locking block 530 is locked in the locking cavity.

[0042] A first groove 532 is formed on the top surface of the first locking block 530. The top surface of the first locking block 530 abuts against the main end wall 512, so that the first groove 532 and the main end wall 512 enclose and define the aforementioned limiting cavity 550. The main end wall 512 defines the first limiting surface 551 of the limiting cavity 550, and the first groove 532 defines the second limiting surface 552 of the limiting cavity 550. Both the main end wall 512 and the first locking block 530 are provided with through holes 580 with a diameter smaller than that of the limiting part 410. The rope of the pull rope 400 is allowed to pass through the through hole 580, while the limiting part 410 of the pull rope 400 is restricted from passing through the through hole 580. Thus, while the rope of the pull rope 400 passes through the limiting cavity 550, the limiting part 410 of the pull rope 400 is confined within the limiting cavity 550.

[0043] Since the main end wall 512 is fixedly installed in the inner bushing 511 and the first locking block 530 is locked in the locking cavity, the position of the first limiting surface 551 defined by the main end wall 512 and the position of the second limiting surface 552 defined by the first groove 532 are fixed relative to the secondary rod 300.

[0044] During the extension of the rod structure, the lower rod 200 moves to the maximum extension position before the secondary rod 300. At this time, the upper half of the pull rope 400 is slack, and the lower half of the pull rope 400 is taut. The limiting part 410 of the pull rope 400 abuts against the second limiting surface 552 of the limiting cavity 550, that is, the limiting part 410 abuts against the first groove 532 of the first locking block 530. The lower rod 200 can drive the secondary rod 300 to extend synchronously relative to the upper rod 100 through the lower half of the pull rope 400.

[0045] When the pole structure is extended to its maximum length, both the secondary pole 300 and the lower pole 200 move to their maximum extended positions. At this time, the upper and lower halves of the pull rope 400 are taut, and the limiting part 410 of the pull rope 400 abuts against the first limiting surface 551 of the limiting cavity 550, that is, the limiting part 410 abuts against the main end wall 512. The secondary pole 300 is restricted by the upper half of the pull rope 400 and cannot extend further outward, thereby preventing the secondary pole 300 from being separated from the upper pole 100 due to overextension caused by misoperation or external force, thus improving the user experience of the trekking pole.

[0046] Preferably, the limiting part 410 is implemented as a knot, which can be a half knot, a reverse knot, a Peruvian knot, etc. While the rope 400 limits the extension length of the rod structure, the knot is further tightened under the action of tension, resulting in an increase in the length of the rope 400 at both ends of the knot. The position of the knot on the rope 400 is offset to a certain extent. In the rod structure of this application embodiment, even if the position of the knot is offset, it can always remain within the limiting cavity 550 under the constraint of the fixed first limiting surface 551 and the second limiting surface 552. The knot can always play the role of synchronously driving the secondary rod 300 to extend in conjunction and preventing the secondary rod 300 from detaching from the upper rod 100 during the extension of the rod structure.

[0047] When assembling the pull rope 400 with the mating part 500, only three steps are required: "winding the pull rope 400 itself into a knot", "passing the two ends of the pull rope 400 through the main end wall 512 and the first locking block 530 respectively", and "installing and locking the first locking block 530 in the locking cavity". The assembly process is simple and convenient, and it is easier for assembly personnel to master the assembly process. It can reduce product quality problems caused by improper operation or assembly errors, and the assembly time is greatly shortened, shortening the product production cycle and reducing production costs.

[0048] In other embodiments, such as Figure 7-9 As shown, the main body 510 includes an inner sleeve 511 and a second locking block 513 that is independent and separable from the main body 510. The second locking block 513 is disposed on the inner sleeve 511. The locking clamp 520 includes four axially extending locking clamp walls 521 and abutting members 522 disposed at the ends of the locking clamp walls 521. The four locking clamp walls 521 are circumferentially arranged around the bottom of the inner sleeve 511, and the four locking clamp walls 521 enclose and define a locking cavity. The abutting members 522 are adapted to abut against and cooperate with the first locking block 530 to lock the first locking block 530 in the locking cavity. A locking groove 523 is also formed between two adjacent locking clamp walls 521. A second locking rib 514 that matches the locking groove 523 is provided on the outer peripheral wall of the second locking block 513. A first locking rib 531 that matches the locking groove 523 is provided on the outer peripheral wall of the first locking block 530. When the second locking block 513 and the first locking block 530 are mounted on the main body 510, the top of the second locking rib 514 of the second locking block 513 abuts against the inner bushing 511, the top surface of the first locking block 530 abuts against the bottom surface of the second locking block 513, the locking groove 523 receives the second locking rib 514 of the second locking block 513 and the first locking rib 531 of the first locking block 530, and the abutting member 522 abuts against the bottom surface of the second locking block 513, so that the second locking block 513 and the first locking block 530 are locked in the locking cavity.

[0049] The second locking block 513 has a second groove 515 on its bottom surface, and the first locking block 530 has a first groove 532 on its top surface. The bottom surface of the second locking block 513 abuts against the top surface of the first locking block 530, so that the second groove 515 and the first groove 532 enclose and define the aforementioned limiting cavity 550. The second groove 515 defines the first limiting surface 551 of the limiting cavity 550, and the first groove 532 defines the second limiting surface 552 of the limiting cavity 550. Both the second locking block 513 and the first locking block 513 have through holes 580 with a diameter smaller than that of the limiting part 410. The rope of the pull rope 400 is allowed to pass through the through hole 580, while the limiting part 410 of the pull rope 400 is restricted from passing through the through hole 580. Thus, while the rope of the pull rope 400 passes through the limiting cavity 550, the limiting part 410 of the pull rope 400 is confined within the limiting cavity 550.

[0050] Since the second locking block 513 and the first locking block 530 are locked in the locking cavity, the position of the first limiting surface 551 defined by the second groove 515 and the position of the second limiting surface 552 defined by the first groove 532 are fixed relative to the secondary rod 300.

[0051] During the extension of the rod structure, the lower rod 200 moves to the maximum extension position before the secondary rod 300. At this time, the upper half of the pull rope 400 is slack, and the lower half of the pull rope 400 is taut. The limiting part 410 of the pull rope 400 abuts against the second limiting surface 552 of the limiting cavity 550, that is, the limiting part 410 abuts against the first groove 532 of the first locking block 530. The lower rod 200 can drive the secondary rod 300 to extend synchronously relative to the upper rod 100 through the lower half of the pull rope 400.

[0052] When the pole structure is extended to its maximum length, both the secondary pole 300 and the lower pole 200 move to their maximum extended positions. At this time, the upper and lower halves of the pull rope 400 are taut, and the limiting part 410 of the pull rope 400 abuts against the second limiting surface 552 of the limiting cavity 550, that is, the limiting part 410 abuts against the second groove 515 of the second locking block 513. The secondary pole 300 is restricted by the upper half of the pull rope 400 and cannot extend further outward, thereby preventing the secondary pole 300 from being separated from the upper pole 100 due to overextension caused by misoperation or external force, thus improving the user experience of the trekking pole.

[0053] Preferably, the limiting part 410 is implemented as a knot, which can be a half knot, a reverse knot, a Peruvian knot, etc. While the rope 400 limits the extension length of the rod structure, the knot is further tightened under the action of tension, resulting in an increase in the length of the rope 400 at both ends of the knot. The position of the knot on the rope 400 is offset to a certain extent. In the rod structure of this application embodiment, even if the position of the knot is offset, it can always remain within the limiting cavity 550 under the constraint of the fixed first limiting surface 551 and the second limiting surface 552. The knot can always play the role of synchronously driving the secondary rod 300 to extend in conjunction and preventing the secondary rod 300 from detaching from the upper rod 100 during the extension of the rod structure.

[0054] When assembling the pull rope 400 with the mating part 500, only three steps are required: "winding the pull rope 400 itself into a knot", "passing the two ends of the pull rope 400 through the second locking block 513 and the first locking block 530 respectively", and "installing and locking the second locking block 513 and the first locking block 530 in the locking cavity 524". The assembly process is simple and convenient, and it is easier for assembly personnel to master the assembly process. It can reduce product quality problems caused by improper operation or assembly errors, and the assembly time is greatly shortened, thus shortening the product production cycle and reducing production costs.

Those skilled in the art should understand that this application is not limited to the above embodiments.
