[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] like Figure 1-11 As shown, the present application provides a locking device, which is suitable for locking and clamping two sections of a trekking pole with different thicknesses. The user can lock or unlock the two sections of the pole by operating the locking device, thereby facilitating the user to adjust the trekking pole to a desired length. The locking device is not only convenient to lock but also firmly locks, providing a good user experience.

[0037] The locking device includes an adjustment component 100, a tension component 200 and a connecting tube 300. A clamping portion 310 is provided at one end of the connecting tube 300. A first accommodating chamber 320 for installing a thin rod body of a trekking pole is provided in the clamping portion 310. A second accommodating chamber 330 for installing a thick rod body of a trekking pole is provided in the connecting tube 300. The first accommodating chamber 320 is connected to the second accommodating chamber 330. The inner diameter d of the first accommodating chamber 320 is smaller than the inner diameter D of the second accommodating chamber 330. The inner diameters of the first accommodating chamber 320 and the second accommodating chamber 330 are Half of the difference is the wall thickness of the thick rod H, that is, H = (Dd) / 2, and then when the thick rod is installed in the second accommodating cavity 330, the inner wall of the clamping part 310 can be connected with the inner wall of the thick rod as a whole, and the sliding and telescopic movement of the thin rod relative to the thick rod in the first accommodating cavity 320 will not be hindered; the adjustment component 100 is clamped on the clamping part 310, and the adjustment component 100 is used to change the inner diameter of the first accommodating cavity 320 in the clamping part 310, so that the clamping part 310 can clamp and lock the thin rod, thereby limiting the telescopic sliding of the thin rod relative to the thick rod.

[0038] like Figure 2-9 As shown, the adjustment assembly 100 includes a clamp 110, a lock 120 and a pull button 130. The clamp 110 includes a left clamp block 111 and a right clamp block 112. The left clamp block 111 and the right clamp block 112 enclose a clamping space. The clamp 110 is sleeved on the clamping portion 310 so that the clamping portion 310 is located in the clamping space. The clamp 110 is movably connected with the lock 120, and the lock 120 is movably connected with the pull button 130. The pull button 130 is movably connected to the clamp 110. The pull button 130 can be pulled relative to the clamp 110 and rotated between a locked position and an unlocked position to drive the left clamp block 111 and the right clamp block 112 to move closer to each other to clamp the clamping portion 310 or separate from each other to loosen the clamping portion 310, thereby changing the inner diameter of the first accommodating cavity 320 to achieve locking or releasing the locking of the thin rod body.

[0039] Furthermore, if Figure 2-8As shown, the first ends 113 of the left clamp block 111 and the right clamp block 112 are hinged to each other, and the second ends 114 of the left clamp block 111 and the right clamp block 112 are arranged at intervals. The pull button 130 includes an operating end 132 and a driving end 131. The driving end 131 of the pull button 130 is movably connected to the second end 114 of the right clamp block 112. One end of the lock buckle 120 is movably connected to the second end 114 of the left clamp block 111 to form a fixed end 121, and the other end of the lock buckle 120 is movably connected to the pull button 130 to form a free end 122. Then, the pull button 130 can be pulled and rotated between a locked position and an unlocked position to drive the lock buckle 120 to tighten the left clamp block 111 and the right clamp block 112 or drive the lock buckle 120 to loosen the left clamp block 111 and the right clamp block 112. When the pull button 130 is pulled to the locking position, the pull button 130 is attached to the right clamping block 112, and the pull button 130 drives the lock button 120 to tighten the left clamping block 111 and the right clamping block 112, so that the left clamping block 111 and the right clamping block 112 are close to each other and exert a radial force on the clamping portion 310. The clamping portion 310 is deformed under the action of the radial force, and the inner diameter of the first accommodating cavity 320 is also reduced. The clamping portion 310 clamps the thin rod body arranged in the first accommodating cavity 320 to lock the thin rod body; when the pull button 130 is pulled to the When in the unlocked position, the pull button 130 moves away from the right clamp block 112 and separates from the right clamp block 112. The pull button 130 drives the lock button 120 to loosen the left clamp block 111 and the right clamp block 112. The radial force applied by the left clamp block 111 and the right clamp block 112 on the clamping portion 310 is removed. The clamping portion 310 is no longer subjected to the radial force and recovers its deformation. The inner diameter of the first accommodating cavity 320 also recovers to its original state. The clamping portion 310 releases the lock on the thin rod body, and the thin rod body can slide and retract in the first accommodating cavity 320 relative to the thick rod body and the clamping portion 310.

[0040] exist Figure 2-3In the embodiment shown, two first connecting ears 115 are provided on the second end 114 of the left clamping block 111, and an opening for accommodating the lock buckle 120 is formed between the two first connecting ears 115. The fixed end 121 of the lock buckle 120 is axially connected to the two first connecting ears 115 and is arranged in the opening between the two first connecting ears 115; two second connecting ears 116 are provided on the second end 114 of the right clamping block, and an opening for accommodating the pull buckle 130 is formed between the two second connecting ears 116. The driving end 131 of the pull buckle 130 includes two rotating blocks. 133, the two rotating blocks 133 are axially connected to the second connecting ears 116 and are arranged in the opening between the two second connecting ears 116, and a cavity for accommodating the lock buckle 120 is also formed between the two rotating blocks 133, and sliding grooves 134 are respectively opened on the two rotating blocks 133, and a connecting shaft 123 is arranged on the free end 122 of the lock buckle 120, and the connecting shaft 123 is movably arranged in the sliding groove 134 so that the free end 122 of the lock buckle 120 is movably connected to the pull buckle 130, and the free end 122 of the lock buckle 120 is located in the cavity between the two rotating blocks 133.

[0041] Furthermore, if Figure 1-3 and Fig. 9 As shown, the tensioning assembly 200 includes a tensioning block 210, a tensioning knob 220 and a threaded rod 230. A rotating slot 124 is also provided on the free end 122 of the lock buckle 120. The connecting shaft 123 passes through the rotating slot 124, and a tensioning block 210 is sleeved on the connecting shaft 123. The tensioning block 210 is arranged in the rotating slot 124 and can rotate relative to the connecting shaft 123. A threaded rod 230 is also fixedly connected to the tensioning block 210. A tensioning knob 220 is movably provided on the driving end 131 of the pull buckle 130. The tensioning knob 220 is threadedly connected to the threaded rod 230, and then the tensioning knob 220 can be rotated to make the tensioning block 210 approach or move away from the tensioning knob 220, thereby changing the size of the inner diameter of the first accommodating cavity 320 after the adjustment assembly 100 is locked, so that the clamping portion 310 can lock thin rods of different diameters, thereby improving the applicability of the locking device.

[0042] In some preferred embodiments, Figure 10-11 As shown, the clamping portion 310 includes at least two elastic clamping members 311, each of which is arranged along the circumference and at intervals on the connecting tube 300, each of which surrounds a cylindrical first accommodating cavity 320, and a gap is provided between two adjacent elastic clamping members 311. Preferably, the number of the elastic clamping members 311 is two.

[0043] Furthermore, in order to facilitate the connection of the adjustment component 100 to the clamping portion 310 and prevent the adjustment component 100 from sliding off the clamping portion 310, a limiting portion 312 is provided at the end of each elastic clamping member 311 away from the connecting tube 300, and the limiting portion 312 and the connecting tube 300 define a connecting groove on the outer wall of each elastic clamping member 311. When the left clamping block 111 and the right clamping block 112 are arranged on the clamping portion 310, the top end surfaces of the left clamping block 111 and the right clamping block 112 abut against the limiting portion 312, and the bottom end surfaces of the left clamping block 111 and the right clamping block 112 abut against the connecting tube 300. The left clamping block 111 and the right clamping block 112 are embedded in the connecting groove, which facilitates the user to install the adjustment component 100 on the clamping portion 310 while preventing the adjustment component 100 from sliding off the clamping portion 310 during use.

[0044] Preferably, in order to limit the rotation of the adjustment assembly 100 relative to the clamping portion 310, at least one of the elastic clamping members 311 is provided with a protrusion 313, and the clamp 110 is provided with a bayonet 140 adapted to the protrusion 313. Specifically, the outer walls of the two elastic clamping members 311 are provided with a protrusion 313, and the left clamping block 111 and the right clamping block 112 are provided with a bayonet 140, and the position of each bayonet 140 corresponds to the position of each protrusion 313. When the adjustment assembly 100 is set on the clamping portion 310, the protrusion 313 cooperates with the bayonet 140 to improve the stability of the adjustment assembly 100 being clamped on the clamping portion 310.

[0045] The present application also provides a trekking pole, which includes the above-mentioned locking device and a thick rod body and a thin rod body that can be telescopically connected to each other. The thin rod body is arranged in the first accommodating chamber 320, and the thick rod body is arranged in the second accommodating chamber 330. The user can lock or unlock the thin rod body by operating the pull button 130. The user can also change the inner diameter of the first accommodating chamber 320 after locking by operating the tension knob 220, so that the clamping part 310 can lock thin rod bodies of different diameters.

[0046] The specific implementation process of this embodiment is as follows:

[0047] When the overall length of the trekking pole needs to be adjusted, the user can rotate the pull button 130 from the locked position to the unlocked position, and the pull button 130 drives the lock button 120 to loosen the left clamp block 111 and the right clamp block 112, so that the radial force of the left clamp block 111 and the right clamp block 112 on the clamping portion 310 is removed, and each elastic clamping member 311 recovers its deformation, and the clamping portion 310 releases the lock on the elastic clamping member 311, so that the thin rod body can slide and retract relative to the thick rod body; when the overall length of the trekking pole needs to be locked after the adjustment is completed, the user can lock it. The pull button 130 can be rotated from the unlocking position to the locking position, and the pull button 130 drives the lock button 120 to tighten the left clamping block 111 and the right clamping block 112. The left clamping block 111 and the right clamping block 112 move closer to each other and apply a radial force to the clamping portion 310. Each elastic clamping member 311 is deformed under the action of the radial force, so that the inner diameter of the first accommodating cavity 320 becomes smaller and clamps the thin rod body, thereby locking the thin rod body to meet the locking requirements of the trekking pole for the thin rod body and the thick rod body. The locking operation is convenient and the locking is firm.

[0048] In addition, the user can also rotate the tension knob 220 to adjust the inner diameter of the first accommodating cavity 320 after the adjustment assembly 100 is locked to clamp rods of different diameters. For example, when the elastic clamping members 311 cannot clamp a thin rod after the adjustment assembly 100 is locked, the user can rotate the tension knob 220 to move the tension adjustment block 210 closer to the tension knob 220, so that the left clamping block 111 and the right clamping block 112 can be further brought closer after the trigger 130 is rotated to the locked position, the deformation degree of each elastic clamping member 311 is aggravated, and the inner diameter of the first accommodating cavity 320 is further reduced, so that each elastic clamping member 311 can clamp a thin rod with a smaller diameter; similarly, the user can also rotate the tension knob 220 to move the tension adjustment block 210 away from the tension knob 220, and each elastic clamping member 311 can clamp a thin rod with a larger diameter.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
