Description

Technical Field

[0001] The utility model relates to the technical field of external locking of trekking poles, and more specifically to an external locking mechanism for trekking poles and a trekking pole. Background Art

[0002] In the current market, the design of trekking poles is mainly focused on telescopic structures. The core advantage of this structure is its adjustability, allowing users to adjust the length of the pole according to different terrains and climbing needs. The flexibility of this design greatly enhances the practicality of trekking poles. However, the locking mechanism of telescopic trekking poles usually relies on a rotating sleeve locking fixing structure, which achieves locking by cooperating with an elastic claw sleeve with an external thread on the internal pipe.

[0003] Although the rotating sleeve locking structure can provide sufficient locking force in the initial stage, over time and with frequent use, the threads of this structure may gradually lose their tightening effect due to wear, causing the locking to loosen or even fall off. This situation not only affects the stability and safety of the trekking pole, but also may bring potential risks to climbers. Summary of the invention

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes an external locking mechanism for a trekking pole, which drives a connecting arm by a wrench to move the second end toward / away from the first end to reduce / enlarge the locking gap to achieve fast and firm locking / unlocking, thereby enhancing the ease of use and safety of the trekking pole.

[0005] The utility model also provides a trekking pole with an external locking mechanism.

[0006] The technical solution adopted by the utility model is to provide an external locking mechanism for a trekking pole, comprising:

[0007] A lock buckle used for sleeved on the end of the outer rod, the lock buckle having a first end and a second end opposite to each other, and a locking gap is provided between the first end and the second end along the axial direction;

[0008] a wrench, one end of which is hinged to the first end of the lock;

[0009] A connecting arm, one end of which is hinged to the middle of the wrench, and the other end of which is hinged to the second end of the lock.

[0010] With the above structure, the design of the external locking mechanism avoids the wear problem that may occur in the traditional embedded rotating sleeve locking structure. Due to the combination of the lock buckle, the wrench and the connecting arm, the user can adjust and lock the length of the trekking pole through simple operations without multiple rotations. That is, when the external locking mechanism is locked, the wrench is tightened. The wrench pushes the second end toward the first end through the connecting arm, so that the locking gap is reduced to achieve the purpose of locking. This design not only simplifies the operation process, but also improves the efficiency and reliability of locking.

[0011] When the user needs to adjust the length of the trekking pole, he only needs to operate the wrench, and the wrench drives the connecting arm to move the second end away from the first end to expand the locking gap and achieve the purpose of unlocking. The inner rod can freely extend and retract in the lock. Once the desired length is reached, the user operates the wrench again, and the first and second ends of the lock can be tightly closed through the action of the connecting arm, thereby achieving a quick and secure lock. The intuitiveness and ease of use of this design make it easy for climbers of different ages and skill levels to master it, so that they can enjoy more convenient and safe support in various climbing environments.

[0012] According to one embodiment of the utility model, the first end of the lock buckle protrudes outward to form two first ears arranged at intervals, and one end of the wrench is located between the two first ears; the setting of the first ear allows the first end and the wrench to move relative to each other while maintaining structural stability, thereby reducing the relative shaking of the wrench and the lock buckle.

[0013] According to an embodiment of the utility model, the first ear portion is provided with a first axial hole, the wrench is provided with a third axial hole, and the wrench and the lock buckle are hinged by passing a first pin through the first axial hole and the third axial hole; the above arrangement facilitates the assembly between the wrench and the lock buckle.

[0014] According to an embodiment of the utility model, the second end of the lock buckle protrudes outward to form two second ears arranged at intervals, and one end of the connecting arm is located between the two second ears.

[0015] According to an embodiment of the utility model, the second ear portion is provided with a second axial hole, and the third pin passes through the second axial hole and the connecting arm to realize the hinge connection between the connecting arm and the lock buckle.

[0016] According to an embodiment of the utility model, a mounting groove is provided in the middle of the wrench, the connecting arm is located in the mounting groove and is hinged to the side wall of the mounting groove.

[0017] According to an embodiment of the utility model, a fourth axial hole is provided on the side wall of the installation groove, and the second pin passes through the fourth axial hole and the connecting arm to realize the hinge connection between the connecting arm and the wrench.

[0018] According to an embodiment of the utility model, at least one of the lock buckle and the wrench is provided with a material reduction groove; the main purpose of the material reduction groove is to reduce the weight of the part while maintaining sufficient structural strength and functionality. To a certain extent, the material reduction groove can also increase the aesthetics of the part and save materials; and / or

[0019] The lock buckle is provided with a positioning protrusion; correspondingly, a notch adapted to the positioning protrusion is provided at the end of the outer rod of the trekking pole, so that the positioning protrusion is inserted into the notch to prevent relative rotation between the lock buckle and the outer rod.

[0020] According to an embodiment of the utility model, the wrench is arc-shaped as a whole, and when the locking mechanism is locked, the free end of the wrench contacts the outer surface of the lock buckle.

[0021] A trekking pole comprises an outer rod and any one of the above-mentioned external locking mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS
