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 commonly used auxiliary equipment in outdoor mountaineering and hiking. They help hikers maintain balance, reduce leg strain, conserve energy, and can also prevent falls and injuries to some extent. To make trekking poles easy to carry and adaptable to people of different heights, existing trekking poles typically feature an adjustable, telescopic shaft structure. This structure consists of at least two hollow tubes joined together, with the relative sliding between the tubes allowing for switching between the active and folded states. Furthermore, external locking mechanisms such as elastic buttons and rotating cam locks secure the tubes to the desired length.

[0003] However, the above combination of "telescopic tube and button / lock" has the following shortcomings: 1. The extension and folding operation is cumbersome, with many steps and a long time required, and users need to operate each tube and locking mechanism in sequence; 2. The exposed structure is easily damaged, and exposed parts such as elastic buttons and rotary cam locks are easily corroded when exposed to rain and mud for a long time; 3. The risk of misoperation is high, and the button structure is easily accidentally activated during mountaineering and hiking, causing the pole structure to retract unexpectedly and creating a safety hazard; 4. It is difficult to balance the issues of "quick folding" and "anti-disconnection". Summary of the Invention

[0004] One objective of this application is to provide a rod structure that is simple in structure and can be quickly switched between a used state and a folded state.

[0005] Another purpose of this application is for trekking poles.

[0006] To achieve the above objectives, the technical solution adopted in this application is: a rod structure, comprising:

[0007] Upper rod body;

[0008] The secondary rod is telescopically connected to the upper rod.

[0009] At least one lower rod body, the lower rod body being detachably inserted into the secondary rod body;

[0010] The system also includes a conversion assembly, which comprises a first pull rope, a second pull rope, and a main control unit. The first pull rope is located inside the upper rod body and one end of the first pull rope is connected to the upper rod body. The main control unit is movably disposed on the first pull rope. The second pull rope is located inside the secondary rod body and the lower rod body, and both ends of the second pull rope are respectively connected to the main control unit and the lower rod body.

[0011] When the pole structure is in use, the main control unit is locked to the secondary pole, the main control unit is limited to the end of the secondary pole, the second pull rope is in a taut state, and the lower pole is inserted into the secondary pole or the lower pole is inserted into another adjacent lower pole.

[0012] When the rod structure is in a folded state, the main control unit is unlocked from the secondary rod, the main control unit is moved into the interior of the secondary rod, the second pull rope is in a slack state, and the lower rod is separated from the secondary rod or separated from another adjacent lower rod.

[0013] In some embodiments, a first elastic element is provided in the lower rod body located at the end of the rod structure. The two ends of the first elastic element are respectively connected to the lower rod body and the second pull rope. The first elastic element is adapted to apply an axial force to the lower rod body and the second pull rope respectively. The direction of the force acting on the lower rod body is towards the upper rod body, and the direction of the force acting on the second pull rope is away from the upper rod body.

[0014] In some embodiments, a flange sleeve is provided at the first end of the secondary rod, and a locking buckle is movably provided on the main control unit. The locking buckle can be moved to a locked position and an unlocked position. When the locking buckle is in the locked position, it abuts against the flange sleeve, and the main control unit is confined to the first end of the secondary rod. When the locking buckle is in the unlocked position, it does not abut against the flange sleeve, and the main control unit is moved into the interior of the secondary rod.

[0015] In some embodiments, a second elastic member is provided between the locking buckle and the main control unit, with the two ends of the second elastic member respectively abutting against the locking buckle and the main control unit, and the second elastic member is adapted to push the locking buckle from the unlocked position to the locked position.

[0016] In some embodiments, the upper rod body is provided with an unlocking member inside, which is adapted to push the locking buckle from the locked position to the unlocked position.

[0017] In some embodiments, a first end of the lower rod is provided with a plug-in rod, one end of which is disposed inside the lower rod to form an embedded end, and the other end of which extends to the outside of the lower rod to form an external end. The external end of the plug-in rod is adapted to be separably embedded inside the secondary rod or inside an adjacent lower rod.

[0018] In some embodiments, the outer end of the plug-in rod is connected to a guide end cap, the guide end cap having a tapered guide surface adapted to abut against the end of the secondary rod or the end of an adjacent lower rod to guide the plug-in rod to be embedded inside the secondary rod or the interior of an adjacent lower rod.

[0019] In some embodiments, a locking assembly is provided at the second end of the upper rod, the locking assembly being adapted to lock or unlock the secondary rod. When the secondary rod is locked, the secondary rod cannot extend or retract axially relative to the upper rod. When the secondary rod is unlocked, the secondary rod is adapted to extend or retract axially relative to the upper rod.

[0020] In some embodiments, a limiting member is provided on the first pull rope, the limiting member being adapted to abut against the main control unit to limit the extreme position of the main control unit.

[0021] On the other hand, this application also provides a trekking pole, including a handle, a tip, and the aforementioned pole structure.

[0022] Compared with the prior art, the beneficial effects of this application are as follows:

[0023] Through the telescopic connection between the secondary pole and the upper pole, the plug-in connection between the lower pole and the secondary pole, and the setting of the conversion component, the user only needs to extend or retract the secondary pole to a specific position to switch the pole structure of this application between the use state and the folded state. At the same time, when the pole structure is in the use state, the conversion component can restrict the secondary pole from detaching from the upper pole and restrict the lower pole from detaching from the secondary pole, avoiding safety hazards caused by the accidental retraction of the pole structure during mountaineering and hiking.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] like Figure 1 As shown in the figure, this application provides a trekking pole, which includes a handle structure, a shaft structure and a tip structure, wherein the handle structure and the tip structure are respectively connected to both ends of the shaft structure.

[0043] The rod structure includes an upper rod 100, a secondary rod 200, and at least one lower rod 300.

[0044] Upper rod 100, which is adapted to be connected to the handle structure.

[0045] like Figure 2 As shown, the first end of the upper rod 100 is connected to the handle structure; the first end of the upper rod 100 is provided with a connecting end cap 110, which is adapted to be connected to the first pull rope 410 described below; the first end of the upper rod 100 is provided with an unlocking member 120, which is adapted to push the locking buckle 450 described below from the locked position to the unlocked position. In this embodiment, the unlocking member 120 is integrally integrated into the connecting end cap 110, and the unlocking member 120 is implemented as the side wall of the connecting end cap 110. Therefore, when the upper rod 100 is retracted to a specific position, the side wall of the connecting end cap 110 pushes the locking buckle 450 from the locked position to the unlocked position. The second end of the upper rod 100 is provided with a locking assembly 130, which is adapted to lock or unlock the secondary rod 200 described below. The type of locking assembly 130 is not limited, and the locking assembly 130 can be implemented as a common expansion locking structure, quick-release eccentric lock structure, etc.

[0046] Secondary rod 200 is adapted to be telescopically connected to upper rod 100.

[0047] like Figure 3As shown, the secondary rod 200 is telescopically connected to the second end of the upper rod 100. The secondary rod 200 is adapted to be locked or unlocked by the locking assembly 130. When the locking assembly 130 locks the secondary rod 200, the secondary rod 200 cannot telescopically extend or retract relative to the upper rod 100 in the axial direction. When the locking assembly 130 unlocks the secondary rod 200, the secondary rod 200 can telescopically extend or retract relative to the upper rod 100 in the axial direction. The first end of the secondary rod 200 is also provided with a flange sleeve 210, which is adapted to abut against the locking buckle 450 described below.

[0048] And at least one lower rod body, the lower rod body being adapted to be separably inserted into the secondary rod body 200, and the lower rod body being adapted to be connected to the tip structure.

[0049] like Figure 4 As shown, the rod structure includes two lower rods 300, namely a first lower rod 310 closer to the secondary rod 200 and a second lower rod 320 farther from the secondary rod 200. The first lower rod 310 is detachably inserted into the second end of the secondary rod 200, and the second lower rod 320 is detachably inserted into the second end of the first lower rod 310. The rod tip structure is connected to the second end of the second lower rod 320. The first end of the first lower rod 310 and the second lower rod 320 are each provided with a connecting rod 330. One end of the connecting rod 330 is located inside the first lower rod 310 and the second lower rod 320 to form an embedded end, and the other end of the connecting rod 330 extends to the outside of the first lower rod 310 and the second lower rod 320 to form an external end. The external end of the connecting rod 330 is suitable for being separably embedded in the secondary rod 200 or the first lower rod 310, so that the first lower rod 310 can be separably inserted into the secondary rod 200 and the second lower rod 320 can be separably inserted into the first lower rod 310.

[0050] Furthermore, such as Figure 5 As shown, the outer end of the insertion rod 330 is provided with a guide end cap 340, which is threadedly connected to the insertion rod 330. The guide end cap 340 is provided with a conical guide surface 341, which is adapted to abut against the end of the secondary rod 200 or the end of the first lower rod 310 to guide the insertion rod 330 to move and embed into the interior of the secondary rod 200 or the first lower rod 310. This improves the smoothness of the insertion of the secondary rod 200 and the first lower rod 310, and the first lower rod 310 and the second lower rod 320, ensuring smooth movement of the rod during axial extension and contraction, reducing friction and shaking, improving structural stability, and preventing jamming or displacement. In addition, the interior of the guide end cap 340 is hollow to allow the second pull rope 420, described below, to pass through.

[0051] Optionally, the rod structure includes only one lower rod 300, which is a first lower rod 310. The first lower rod 310 is detachably inserted into the second end of the secondary rod 200, and the rod tip structure is connected to the second end of the first lower rod 310. The first end of the first lower rod 310 is provided with an insertion rod 330. One end of the insertion rod 330 is located inside the first lower rod 310 to form an embedded end, and the other end of the insertion rod 330 extends to the outside of the first lower rod 310 to form an external end. The external end of the insertion rod 330 is adapted to be detachably embedded inside the secondary rod 200, so that the first lower rod 310 can be detachably inserted into the secondary rod 200.

[0052] Furthermore, the outer end of the insertion rod 330 is provided with a guide end cap 340, which is threadedly connected to the insertion rod 330. The guide end cap 340 is provided with a conical guide surface 341, which is adapted to abut against the end of the secondary rod 200 to guide the insertion rod 330 to move and embed into the interior of the secondary rod 200. This improves the smoothness of the insertion of the secondary rod 200 and the first lower rod 310, ensures smooth movement of the rod during axial extension and contraction, reduces friction and shaking, improves structural stability, and avoids jamming or displacement. In addition, the interior of the guide end cap 340 is hollow to allow the second pull rope 420, described below, to pass through.

[0053] It is worth noting that the first end of each rod described in this article is the end of each rod that is closer to the handle structure in the axial direction, and the second end of each rod described in this article is the end of each rod that is closer to the tip structure in the axial direction.

[0054] Furthermore, such as Figure 6 As shown, the pole structure also includes a conversion assembly 400, which is adapted to switch the pole structure between a use state and a folded state. The conversion assembly 400 includes a first pull rope 410, a second pull rope 420, and a main control unit 430.

[0055] like Figure 7 and Figure 8 As shown, the first pull rope 410 is located inside the main rod and extends axially along the rod. One end of the first pull rope 410 is connected to the connecting end cap 110, and the other end of the first pull rope 410 is connected to a limiting member 440. The main control unit 430 is axially movable and mounted on the first pull rope 410. The limiting member 440 is adapted to abut against the main control unit 430 to limit the extreme position of the main control unit 430. By limiting the extreme position of the main control unit 430 by the limiting member 440, the secondary rod 200 can be prevented from over-extending and detaching from the upper rod 100.

[0056] Furthermore, such as Figure 7 and Figure 9A locking buckle 450 is rotatably mounted on the main control unit 430. The locking buckle 450 can rotate relative to the main control unit 430 between a locked position and an unlocked position. A second elastic element 460 is provided between the locking buckle 450 and the main control unit 430. The second elastic element 460 is preferably implemented as an elastic torsion spring. One torsion arm of the elastic torsion spring abuts against the main control unit 430, and the other torsion arm of the elastic torsion spring abuts against the locking buckle 450. The elastic torsion spring is adapted to push the locking buckle 450 to rotate it from the unlocked position to the locked position. When the locking buckle 450 is in the unlocked position, it is folded into the main control unit 430, and the locking buckle 450 will not interfere with the flange sleeve 210 and will abut against it. The main control unit 430 can move into the interior of the secondary rod 200. When the locking buckle 450 is in the locked position, it protrudes from the main control unit 430, and the locking buckle 450 will interfere with the flange sleeve 210 and will abut against it. The main control unit 430 cannot move into the interior of the secondary rod 200.

[0057] Optionally, a locking buckle 450 is radially movably provided on the main control unit 430. The locking buckle 450 can move relative to the main control unit 430 between a locked position and an unlocked position. A second elastic element 460 is provided between the locking buckle 450 and the main control unit 430. The second elastic element 460 is preferably implemented as a spring sheet. One end of the spring sheet abuts against the main control unit 430, and the other end of the spring sheet abuts against the locking buckle 450. The spring sheet is adapted to push the locking buckle 450 to move it radially from the unlocked position to the locked position. When the locking buckle 450 is in the unlocked position, it is folded into the main control unit 430, and the locking buckle 450 will not interfere with the flange sleeve 210 and will abut against it. The main control unit 430 can move into the interior of the secondary rod 200. When the locking buckle 450 is in the locked position, it protrudes from the main control unit 430, and the locking buckle 450 will interfere with the flange sleeve 210 and will abut against it. The main control unit 430 cannot move into the interior of the secondary rod 200.

[0058] like Figure 7 and Figure 10 As shown, the second pull rope 420 is located inside the secondary rod 200, the first lower rod 310, and the second lower rod 320 and extends along the axial direction of the rod. One end of the second pull rope 420 is connected to the main control unit 430, and the other end of the second pull rope 420 is connected to the second lower rod 320. Further, an anti-slip member 470 is provided at the end of the second pull rope 420, and a first elastic member 350 is provided inside the second lower rod 320. The first elastic member 350 is preferably implemented as a compression spring, which is located inside the insertion rod 330. One end of the compression spring abuts against the guide end cap 340, and the other end of the compression spring abuts against the anti-slip member 470. When the compression spring is compressed and deformed, the compression spring can apply an axial force to the second lower rod 320 and the second pull rope 420 respectively. The direction of the force acting on the second lower rod 320 is towards the upper rod 100, and the direction of the force acting on the second pull rope 420 is away from the upper rod 100.

[0059] It is worth noting that the length of the second pull rope 420 is matched with the sum of the lengths of the secondary rod 200 and the first lower rod 310. Therefore, when the first lower rod 310 is inserted into the secondary rod 200, the second lower rod 320 is inserted into the first lower rod 310, and the main control unit 430 is limited to the first end of the secondary rod 200 by contacting the flange sleeve 210 through the locking buckle 450, the compression spring is compressed and deformed. The compression spring applies force to the second lower rod 320 and the second pull rope 420 respectively. The force acting on the second lower rod 320 can press the second lower rod 320 against the first lower rod 310 and press the first lower rod 310 against the secondary rod 200, so as to restrict the second lower rod 320 from detaching from the first lower rod 310 and restrict the first lower rod 310 from detaching from the secondary rod 200. The force acting on the second pull rope 420 can press the main control unit 430 against the secondary rod 200, so as to restrict the main control unit 430 from detaching from the first end of the secondary rod 200. The compression spring can also provide flexible tension when the locking buckle 450 disengages from the flange sleeve 210, and can also provide a compression and rebound feel and an impact sound when the locking buckle 450 abuts against the flange sleeve 210.

[0060] The types of the first pull rope 410 and the second pull rope 420 are not limited, but the first pull rope 410 and the second pull rope 420 are preferably plastic-coated steel wire ropes.

[0061] Based on the above structure, the following describes the condition of each component when the rod structure is in use and when it is folded.

[0062] like Figure 7 As shown, the rod structure is in use. In this state, the locking buckle 450 is in the locked position and abuts against the flange sleeve 210. One end of the second pull rope 420 is connected to the main control unit 430, and the other end of the second pull rope 420 is connected to the second lower rod 320. The first lower rod 310 is inserted into the second end of the secondary rod 200, and the second lower rod 320 is inserted into the second end of the first lower rod 310. The second pull rope 420 is in a taut state, causing the compression spring to deform under pressure. The compression spring applies pressure to the second lower rod 320 and the second pull rope 420 respectively. An applied force presses the second lower rod 320 against the first lower rod 310 and the first lower rod 310 against the secondary rod 200, thus restricting the first lower rod 310 and the second lower rod 320 from detaching from the secondary rod 200. A force applied to the second pull rope 420 presses the main control unit 430 against the secondary rod 200, thus limiting the main control unit 430 to the first end of the secondary rod 200. In this state, the "combined rod" can slide and extend axially relative to the upper rod 100 to adjust the length of the rod structure, and can be locked or unlocked via the locking assembly 130.

[0063] like Figure 11 As shown, the rod structure is in a folded state. In this state, the latch is in the unlocked position and does not abut against the flange sleeve 210. The main control unit 430 moves into the interior of the secondary rod 200. One end of the second pull rope 420 is connected to the main control unit 430, and the other end of the second pull rope 420 is connected to the second lower rod 320. The secondary rod 200 retracts into the upper rod 100. The first lower rod 310 separates from the secondary rod 200, and the second lower rod 320 separates from the first lower rod 310. The second pull rope 420 is in a slack state, with a portion of the second pull rope 420 exposed between the secondary rod 200 and the first lower rod 310, and also exposed between the first lower rod 310 and the second lower rod 320. In this state, the second pull rope 420 can be bent so that the upper rod 100, the first lower rod 310, and the second lower rod 320 are arranged side by side, as shown. Figure 12 As shown.

[0064] The extension and folding operation of the rod structure provided in this application embodiment is simple and convenient, and can quickly switch between the use state and the folded state.

[0065] Switching the lever structure from its active state to its folded state simply requires retracting the secondary lever by 200 degrees to the locking buckle by 450 degrees and rotating it to the unlocked position. Specifically, as follows... Figure 13 As shown, when the secondary rod 200 retracts to a specific position, the side wall of the connecting end cap 110 abuts against the locking buckle 450, causing it to rotate from the locked position to the unlocked position. The locking buckle 450 does not abut against the flange sleeve 210. Under the action of the second pull rope 420, the main control unit 430 moves into the interior of the secondary rod 200. The first lower rod 310 separates from the secondary rod 200, and the second lower rod 320 separates from the first lower rod 310. Part of the second pull rope 420 is exposed between the secondary rod 200 and the first lower rod 310, as well as between the first lower rod 310 and the second lower rod 320. The rod structure switches to a folded state.

[0066] To switch the rod structure from a folded state to a usable state, simply extend the secondary rod 200 until the locking buckle 450 rotates to the locked position. Specifically, when the secondary rod 200 is extended to a specific position, the main control unit 430 moves to the outside of the secondary rod 200, and the elastic torsion spring pushes the locking buckle 450, causing it to rotate from the unlocked position to the locked position. The locking buckle 450 abuts against the flange sleeve 210, the first lower rod 310 is inserted into the secondary rod 200, and the second lower rod 320 is inserted into the first lower rod 310. The second pull rope 420, through the anti-slip member 470, causes the compression spring to deform under pressure, and the rod structure switches to the usable state.

[0067] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
