Description

Technical Field

[0001] This utility model relates to the field of trekking pole telescopic rod locking technology, specifically a trekking pole locking structure. Background Technology

[0002] To minimize space during storage, many products use telescopic pole structures, such as trekking poles and camera brackets. In addition, to keep the extended position, a locking lever is installed at the connection of the telescopic structure.

[0003] Traditional locking mechanisms often employ a C-shaped structure, with a locking bar inserted through the C-shaped opening. A wrench with a protrusion on one end of the bar is used to tighten the locking mechanism. When tightening, the protrusion presses against the wrench body, and the reaction pulls the locking bar outwards, thus tightening the C-shaped opening of the wrench body. A similar structure is used in patent application CN201821008893.4 entitled "A Quick-Locking Structure for Hiking Poles." However, this type of locking wrench generally requires a sleeve, and the tightening force is relatively small. After long-term use, wear on components (especially the protrusion) can easily lead to locking failure. Therefore, existing locking mechanisms require further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a trekking pole locking structure that is simple in structure, low in manufacturing cost, and has strong locking force.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, the connecting rod is an adjusting screw, the inner end of which is screwed to the second rotating shaft. The opening size of the locking body can be adjusted by the adjusting screw, thereby adjusting the locking force of the latch.

[0009] As an improvement, the outer side of the locking wrench has an arc-shaped structure, and a pressing surface connected to the arc-shaped structure is provided. This design makes the locking wrench easier to press.

[0029] The connecting rod 5 is an adjusting screw, the inner end of the adjusting screw is screwed with the second rotating shaft 4. When assembling, the adjusting screw is inserted from the first rotating shaft 2 and screwed with the second rotating shaft 4, and by adjusting the screwing depth of the adjusting screw, the opening size of the locking body 1 (the locking body 1 is in a C-shaped structure) can be adjusted, and then the locking force of the lock is adjusted.

[0030] Part of the second rotating shaft 4 is located in the projection of the C-shaped structure of the locking body 1, which can prevent the second rotating shaft 4 from sliding out and ensure the reliability of the lock.

[0031] The outer side of the locking wrench 3 is an arc-shaped structure 3a, and a pressing plane 3b connected with the arc-shaped structure 3a is arranged. The locking wrench 3 is pressed towards the locking body 1, and the user presses the locking wrench 3 along the outer side surface of the locking wrench 3. The design of the arc-shaped structure 3a and the pressing plane 3b makes the pressing more convenient.

[0032] The end of the locking wrench 3 is provided with an inwardly inclined wrenching plane 3c. When unlocking, the locking wrench 3 is pulled away from the locking body 1, and the wrenching plane 3c is arranged to facilitate the force exertion when pulling.

[0035] The other end of the locking body 1 is provided with a second hinge column 62, and the locking wrench 3 is in rotating fit with the second hinge column 62.

[0036] The locking body 1 is provided with a positioning protrusion 8 matched with a positioning groove on the hiking stick 7. Through the arrangement of the positioning protrusion 8, the rotation and axial displacement of the locking body 1 when being installed on the hiking stick 7 can be prevented, the assembly is facilitated, and the reliability is improved.

[0037] Working principle:

[0038] The lock structure of the utility model mainly includes a locking body 1, a first rotating shaft 2, a locking wrench 3, a second rotating shaft 4 and a connecting rod 5, wherein the connecting rod 5 is connected between the first rotating shaft 2 and the second rotating shaft 4, at the same time, the second rotating shaft 4 is arranged on the locking wrench 3, and the locking wrench 3 is hinged with the locking body 1, with the rotation of the locking wrench 3, the connecting rod 5 will make a circular motion with the connecting point of the connecting rod 5 and the first rotating shaft 2 as the center.

[0039] Here, the axis of the connecting rod 5 is denoted as L1, and the line connecting the center of the first rotating shaft and the center of the hinge between the locking handle and the locking body is denoted as L2. When the axis of the connecting rod 5 coincides with the line connecting the center of the first rotating shaft and the center of the hinge between the locking handle and the locking body (i.e. L1 coincides with L2), the critical point is reached. When the lock is locked, as the locking handle 3 is pressed, when L1 passes the critical point and is located inside L2, an inward component force is generated, so that the end of the connecting rod 5 close to the locking handle 3 has a tendency to move inward, thereby locking the locking body 1, and avoiding that the lock is unlocked without external force. When the lock is unlocked, as the locking handle 3 is pulled, when L1 passes the critical point and is located outside L2, an outward component force is generated, so that the end of the connecting rod 5 close to the locking handle 3 has a tendency to move outward, thereby making the unlocking more labor-saving.

[0040] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious change based on the content of the present application should be included in the protection scope of the present application.
