Description

Technical Field

[0001] This utility model relates to the technical field of locking mechanisms for trekking poles, and in particular to a locking mechanism for trekking poles. Background Technology

[0002] Trekking poles are crucial auxiliary equipment in outdoor sports such as mountaineering and hiking, effectively improving walking stability, reducing leg load, and decreasing energy expenditure. In complex and varied outdoor environments, users often need to flexibly adjust the length of trekking poles based on factors such as the actual terrain and their physical condition.

[0003] Most trekking poles on the market today use a telescopic design, and the locking mechanisms they come with are diverse. Among them, the rotary locking mechanism is quite common; it uses friction to lock the pole by rotating a component. However, after prolonged and frequent use, this structure is prone to loosening due to wear and tear on the components, and in severe cases, it can even cause the pole to detach, posing a significant safety hazard to the user. Furthermore, it requires multiple rotations to achieve the desired locking state, making the process time-consuming, laborious, and inefficient, greatly impacting the user experience. Utility Model Content

[0004] In view of the shortcomings or problems existing in the prior art, this disclosure provides a locking mechanism for trekking poles. The locking mechanism is reasonably designed and easy to operate when locking.

[0005] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is: a locking mechanism for trekking poles, comprising:

[0006] A locking sleeve having a first clearance space and a clamping inner diameter for clamping trekking poles;

[0007] A latch is at least partially located in the first clearance space, and the latch is provided with a first receiving space;

[0008] The connector is at least partially located in the first receiving space;

[0009] The first end of the latch is hinged to the lock sleeve and the connector respectively, and the hinge point between the latch and the lock sleeve is located inside the hinge point between the latch and the connector.

[0010] In a preferred embodiment, the locking sleeve includes a main body and a connecting block assembly disposed on the main body. The main body has an arc-shaped structure, and the connecting block assembly includes two opposing first connecting blocks and two opposing second connecting blocks. A gap is formed axially between the first connecting blocks and the adjacent second connecting blocks.

[0011] In a preferred embodiment, the latch includes a first part and a second part. The first part includes two parallel connecting rods, one end of which is connected to the second part. The free ends of the two connecting rods are located between two first connecting blocks and are hinged to the first connecting blocks.

[0012] In a preferred embodiment, the free ends of the two connecting rods are respectively provided with first connecting holes along their thickness direction, the two first connecting holes are coaxially arranged, the two first connecting blocks are respectively provided with first through holes, the two first through holes are coaxially arranged, and the two first connecting holes are respectively connected to the two first through holes through two first pins.

[0013] In a preferred embodiment, the first accommodating space is located between the two connecting rods. The connecting member includes a head and a tail. The head is provided with a first shaft hole along its thickness direction. The free ends of the two connecting rods are respectively provided with second connecting holes along their thickness direction. The two second connecting holes are coaxially arranged, and the second connecting holes are connected to the first shaft hole by a second pin.

[0014] In a preferred embodiment, a first arc-shaped clearance recess is provided between the head and the tail.

[0015] In a preferred embodiment, the tail section is provided with a second shaft hole along its thickness direction, and the two second connecting blocks are respectively provided with second through holes.

[0018] In a preferred embodiment, the adjusting channel is provided with an internal thread, and the axis of the adjusting channel is set perpendicular to the axis of the third pin.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0032] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0033] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, the above terms should not be construed as a limitation of this utility model.

[0034] Please refer to Figure 1 and Figure 2 As shown, this application discloses a locking mechanism for trekking poles, including a locking sleeve 1, a locking buckle 2, and a connecting member 3. The locking sleeve 1 is used to fit over the outside of the trekking pole and has a first clearance space. The locking sleeve 1 has a clamping inner diameter for holding the trekking pole. The locking buckle 2 is at least partially located in the first clearance space and has a first receiving space. The first end of the locking buckle 2 is hinged to both the locking sleeve 1 and the connecting member 3. The hinge point between the locking buckle 2 and the locking sleeve 1 is located inside the hinge point between the locking buckle 2 and the connecting member 3. The second end of the locking buckle 2 is used to fit against the locking sleeve 1, locking the locking sleeve 1 and the trekking pole. Rotating the second end of the locking buckle 2 towards the locking sleeve 1 to fit it against the locking sleeve 1 reduces the clamping inner diameter, locking the trekking pole. Rotating (pulling) the second end of the locking buckle 2 in the opposite direction increases the clamping inner diameter, unlocking the locking sleeve 1 and the trekking pole. When the locking sleeve 1 is locked to the trekking pole, the fitting structure between the locking buckle 2 and the locking sleeve 1 forms a closed force-bearing system, avoiding the "slippage" problem that may occur during locking in traditional rotary locking structures. This provides more reliable support for the user, especially when bearing weight. When the locking buckle 2 rotates towards the locking sleeve 1 and engages, the clamping inner diameter of the locking sleeve 1 is forcibly reduced through the mechanical structure, forming a uniform and stable clamping force on the trekking pole, preventing loosening due to uneven force, and making the locking more reliable. The latch 2 is located within the first clearance space of the lock sleeve 1, and the connector 3 is located within the receiving space of the latch 2. The overall structure is more compact and reduces space occupation. The hinge point between the latch 2 and the lock sleeve 1 is located inside the hinge point between the latch 2 and the connector 3. When the latch 2 is turned, the outer hinge point is far from the axis and the lever arm is long, while the inner hinge point is close to the axis and the lever arm is short, forming a force-saving lever. A small turning force can generate a large radial clamping force on the clamping inner diameter. When the latch 2 is turned away from the lock sleeve 1, the first end of the latch 2 is constrained by the hinge point between the latch 2 and the connector 3 and will not move outward, making the entire locking mechanism more stable.

[0035] Please refer to the following: Figure 3As shown, the locking sleeve 1 further includes a main body 4 and a connecting block assembly disposed on the main body 4. The main body 4 has an arc-shaped structure. The connecting block assembly includes two opposing first connecting blocks 5 and two opposing second connecting blocks 6. A gap is formed axially between the first connecting blocks 5 and the adjacent second connecting blocks 6. Specifically, the main body 4 includes a first end and a second end. The two first connecting blocks 5 are disposed at the first end, and the two second connecting blocks 6 are disposed at the second end. The gap is disposed between the first end and the second end. When the second end of the latch 2 is rotated toward the locking sleeve 1 to fit against the locking sleeve 1, the gap gradually decreases. The gap between the first connecting block 5 and the adjacent second connecting block 6 extends to both sides with a relief recess. This relief recess is connected to the gap and is the first relief space. The first relief space is located between the two first connecting blocks 5 (two second connecting blocks 6). The setting of the first relief space facilitates the connection between the latch 2 and the locking sleeve 1. The latch 2 is at least partially located in the first relief space, making the overall structure of the locking mechanism more compact. It is understandable that, since the latch 2 is rotatable, the part of the latch 2 located in the first clearance space is not fixed.

[0036] like Figures 4-5 As shown, the latch 2 includes a first part and a second part 9. The first part includes two parallel connecting rods 10, one end of which is connected to the second part 9. The free ends of the two connecting rods 10 are located between two first connecting blocks 5 and are hinged to the first connecting blocks 5. A first accommodating space is located between the two connecting rods 10. Specifically, the free ends of the two connecting rods 10 are provided with first connecting holes 11 along their thickness direction. The two first connecting holes 11 are coaxially arranged. The two first connecting blocks 5 are provided with first through holes 7, which are coaxially arranged. The two first connecting holes 11 are connected to the two first through holes 7 by two first pins. That is, the two connecting rods 10 are distributed vertically in parallel, and both connecting rods 10 are located between the two first connecting blocks 5. One first pin passes through the first through hole 7 and the first connecting hole 11 located above, and the other first pin passes through the first through hole 7 and the first connecting hole 11 located below, thereby making the latch 2 hinged to the lock sleeve 1. To ensure smooth rotation of the latch 2, a clearance groove is provided between the free end of the first part and the main body 4 to prevent interference between the latch 2 and the lock sleeve 1 during rotation. The second end of the latch 2 is located at the end of the second part 9 of the latch 2. To facilitate rotation and other operations of the latch 2, the second part 9 is provided with an operating hole 15.

[0037] Please refer to Figures 6-7As shown, further, the first accommodating space is located between the two connecting rods 10. The connecting member 3 includes a head 16 and a tail 17. The head 16 has a first shaft hole 18 along its thickness direction. The free ends of the two connecting rods 10 are respectively provided with second connecting holes 12 along their thickness direction. The two second connecting holes 12 are coaxially arranged and connected to the first shaft hole 18 by a second pin, thereby hinged the connecting member 3 to the latch 2. Specifically, the second connecting hole 12 is located close to the first connecting hole 11. In the locked state, the second connecting hole 12 is located outside the first connecting block 5 and the first connecting hole 11. The two vertically distributed connecting rods 10 are the upper rod body and the lower rod body, respectively. The upper end of the second pin does not exceed the upper surface of the upper rod body, and the lower end does not exceed the lower surface of the lower rod body. This arrangement can prevent the second pin from interfering with the first connecting block 5 when the latch 2 rotates. In order to further prevent the second pin from interfering with the first connecting block 5, an avoidance groove can also be provided on the inner surface of the first connecting block 5 facing the latch 2.

[0038] To facilitate the connection of the first pin, a first arc-shaped relief recess 20 is provided between the head 16 and the tail 17 of the connector 3, and the axial projection of the first pin falls on the first arc-shaped relief recess 20.

[0039] The tail portion 17 of the connector 3 has a second shaft hole 19 along its thickness direction. Two second connecting blocks 6 each have a second through hole 8, which are coaxially arranged. The second through holes 8 and the second shaft hole 19 are connected by a third pin, allowing the connector 3 to be hinged to the locking sleeve 1. To avoid interference with the latch 2, the first part of the latch 2 has a smoothly transitioning curved section 13, and a second arc-shaped relief recess 14 is provided on the radially inner side of the curved section 13. Furthermore, the curved section 13 can eliminate stress abrupt changes and increase the structural strength of the latch 2.

[0040] Please refer to Figure 7As shown, it should be noted that the diameter of the second shaft hole 19 is larger than the outer diameter of the third pin, forming a radial displacement clearance between them. The tail 17 of the connector 3 has an adjustment channel 21 that connects to the second shaft hole 19. The adjustment channel 21 is used to engage with a fastener to adjust the constraint state of the third pin within the second shaft hole 19. The second shaft hole 19 is not a traditional "tight fit" hole, but rather an "elongated oval hole" or "elliptical hole" with ample radial dimensions, thus creating a radial displacement clearance between its hole wall and the third pin. This clearance forms a "float" after assembly. The adjustment channel 21 has internal threads, and the fastener is a screw or a tapered bolt. The axis of the adjustment channel 21 is perpendicular to the axis of the third pin. When "tightening" is required, the screw is screwed inward, with the front end of the screw pressing against the cylindrical surface of the third pin, pushing the third pin towards one side of the second shaft hole 19; when "loosening" is required, the screw is unscrewed in the opposite direction. The above adjustments can fine-tune the clamping inner diameter of the locking sleeve 1 to accommodate trekking poles of different thicknesses.

[0041] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
