[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 This utility model discloses an automatic locking mechanism for trekking poles, including a locking mechanism body 1. The locking mechanism body 1 includes a fixing member 11 and a locking sleeve 12 movably sleeved on the outside of the fixing member 11. The fixing member 11 is provided with at least one locking block 14. The locking block 14 and the locking sleeve 12 are engaged by an inclined surface. A latch 141 is provided on one side of the locking block 14. The bottom of the latch 141 away from the locking block 14 is provided with a latch inclined surface 143.

[0029] See Figure 9 The diagram shows the connection between the locking mechanism body 1 and the complete trekking pole. The locking mechanism body 1 is located between the upper section tube 2 and the lower section tube 3 of the trekking pole. The bottom of the lower section tube 3 can be extended by adding a section tube through the locking mechanism body 1 to increase the overall length of the trekking pole. The connection method is the same as the connection method between the upper section tube 2 and the lower section tube 3 of the trekking pole. When in use, the upper section tube 2 and the lower section tube 3 of the trekking pole are connected by an elastic rope. When unlocking, the lifting lock sleeve 12 is released from the limiting position of the locking block 14. The secondary spring 16 rebounds and abuts against the locking block 14, causing the lock buckle 141 to disengage from the locking ring 32. This allows the lower section tube 3 of the trekking pole to be pulled out of the interior of the upper section tube 2 of the trekking pole. At the same time, the elastic rope is stretched. At this time, the lower section tube 3 and the upper section tube 2 of the trekking pole can be stored side by side, greatly reducing the storage space of the trekking pole.

[0030] Specifically, the fastener 11 has at least two connecting seats 13 on its exterior, the locking block 14 is movably disposed inside the connecting seat 13, and the locking sleeve 12 has a limiting groove 122 inside that engages with the exterior of the connecting seat 13.

[0031] In this embodiment, the cooperation between the limiting groove 122 and the connecting seat 13 restricts the rotation of the locking sleeve 12, so that the locking sleeve 12 can only move up and down slightly on the fixing member 11, making it more convenient to use.

[0032] Specifically, a main spring 15 is movably sleeved on the outside of the fixing member 11, the bottom of the main spring 15 contacts the top of the limiting groove 122, and a secondary spring 16 is provided on one side of the locking block 14.

[0033] In this embodiment, the elastic force of the main spring 15 is greater than that of the secondary spring 16. The main spring 15 continuously abuts against the limiting groove 122 through its elastic force, causing the limiting groove 122 to drive the guide inclined surface 123 on it to abut against the guide inclined surface 142. The guide inclined surface 142 then drives the locking block 14 to drive the latch 141 to tightly lock the retaining ring 32.

[0034] Specifically, the limiting groove 122 is provided with a guide slope 123, and the top of the locking block 14 away from the secondary spring 16 is provided with a guide slope 142 corresponding to the guide slope 123.

[0035] In this embodiment, when guide ramp 123 abuts against guide ramp 2 142, guide ramp 2 142 applies the force of compressing the secondary spring 16 and the force of locking buckle 141 tightly locking under the retaining ring 32 through locking block 14.

[0036] Specifically, the fastener 11 is provided with a limiting rib 17 located between two connecting seats 13 on the outside, and the locking sleeve 12 is provided with a limiting hook 18 located between two limiting grooves 122 inside, with the end of the limiting hook 18 away from the locking sleeve 12 extending to the bottom of the limiting rib 17.

[0037] In this embodiment, the cooperation between the limiting rib 17 and the limiting hook 18 is mainly used to limit the stroke of the locking sleeve 12. When the locking sleeve 12 is pulled upward, the locking sleeve 12 drives the limiting hook 18 to rise. When the limiting hook 18 hooks the limiting rib 17, the locking sleeve 12 cannot continue to rise. This design avoids the situation where the locking sleeve 12 rises excessively and completely breaks away from the blocking of the locking block 14, causing the locking block 14 to fall off. The locking sleeve 12 reduces unnecessary upward movement, and the operation is more convenient and faster.

[0038] Specifically, the lock sleeve 12 has at least one handle position 121 on its exterior.

[0039] In this implementation scheme, the handle position 121 is designed to make it convenient for users to lift the lock sleeve 12.

[0040] Specifically, it also includes an upper section tube 2 and a lower section tube 3 of the trekking pole. One end of the upper section tube 2 is provided with an upper section tube aluminum guide tube 21. The fixing member 11 is press-fitted with the upper section tube aluminum guide tube 21. One end of the lower section tube 3 is provided with a lower section tube aluminum guide tube 31. One end of the lower section tube aluminum guide tube 31 passes through the fixing member 11 and extends into the interior of the upper section tube aluminum guide tube 21. The lower section tube aluminum guide tube 31 is provided with a retaining ring 32 that engages with the locking buckle 141. The top of the retaining ring 32 is provided with a retaining ring bevel 33 that matches the locking buckle bevel 143.

[0041] In this embodiment, the bottom of the retaining ring 32 is flat, and the top of the latch 141 is flat. (See attached diagram.) Figure 8 When connecting the lower section tube 3 and the upper section tube 2 of the trekking pole, there is no need to pull the locking sleeve 12. The locking ring slope 33 abuts against the locking buckle slope 143, causing the locking buckle slope 143 to drive the locking buckle 141 and the locking block 14 to retract. The guide slope 142 on the locking block 14 abuts against the guide slope 123. The guide slope 123 is forced to automatically drive the locking sleeve 12 to rise and compress the main spring 15. When the locking ring 32 passes the locking buckle 141, the locking buckle 141 is released from the restriction. The main spring 15 rebounds and drives the locking sleeve 12 to reset, so that the locking sleeve 12 abuts against the locking block 14 and drives the locking buckle 141 to engage with the locking ring 32. The planes of the top of the locking buckle 141 and the bottom of the locking ring 32 make contact to lock the locking, preventing the locking buckle 141 from retracting. At this time, when disassembling the lower section tube of the trekking pole, the locking sleeve 12 needs to be manually pulled up.

[0042] In summary, compared to existing trekking pole locking mechanisms on the market, this automatic locking mechanism for trekking poles features a beveled locking sleeve 12 and locking block 14. When connecting the lower section tube 3 and the upper section tube 2 of the trekking pole, they can be directly inserted and locked without the need to operate the locking sleeve 12, making it more convenient to use. When unlocking is required, simply pull the locking sleeve 12, and the locking block 14 will automatically retract and disengage from the limiting position on the lower section tube aluminum guide tube 31, allowing the lower section tube aluminum guide tube 31 to be smoothly pulled out. The cooperation between the limiting hook 18 and the limiting rib 17 restricts the travel of the locking sleeve 12, reducing unnecessary movements and making operation more convenient, thus meeting the user's needs.
