[0026] 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.

[0027] 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.

[0028] exist Figure 1-5 In the illustrated embodiment, the present application provides a locking structure, which includes a locking portion 100 and a movable portion 200, wherein a locking rod 210 is arranged on the movable portion 200, and a locking cavity 110 is provided inside the locking portion 100 for inserting and accommodating the locking rod 210, and two mounting grooves 120 connected to the locking cavity 110 are provided on the side wall of the locking portion 100, and the two mounting grooves 120 are symmetrically arranged along the axis of the locking portion 100, and locking members 130 are rotatably arranged in the two mounting grooves 120, and the user can realize quick locking and quick unlocking of the locking portion 100 and the movable portion 200 by operating the locking member 130 to rotate between a locking position and an unlocking position.

[0029] Specifically, a hinge seat 121 is provided on the two groove walls of the installation groove 120, and an axle pin 131 is provided in the middle of the locking member 130. The locking member 130 is rotatably arranged in the installation groove 120 by cooperating with the hinge seat 121 through the axle pin 131 to form a rotating pair. The locking member 130 forms a pressing end 132 and a locking end 133 at both ends of the axle pin 131 respectively. The end of the locking member 130 close to the movable part 200 is the pressing end 132, and the end of the locking member 130 away from the movable part 200 is the locking end 133. The locking end 133 is suitable for extending into the locking cavity 110 and cooperating with the locking rod 210 to lock and limit the locking rod 210, so that the locking rod 210 cannot slide out of the locking cavity 110 along its axial direction, thereby realizing the locking of the locking part 100 and the movable part 200.

[0030] The pressing end 132 can be pressed or released by the user so that the locking member 130 rotates to the unlocking position or the locking position, that is, the pressing end 132 can be pressed or released so that the locking end 133 tilts up or falls down, so that the locking end 133 cooperates with the locking rod 210 to lock or separate and unlock. Specifically, when the pressing end 132 is not pressed, the locking member 130 is in the locking position, the locking end 133 cooperates with the locking rod 210, and the locking rod 210 cannot move along its axial direction to disengage from the locking cavity 110; when the pressing end 132 is pressed, the locking member 130 rotates to the unlocking position, the locking end 133 tilts up and separates from the locking rod 210, the locking end 133 releases the limit on the locking rod 210, and the locking rod 210 can move along its axial direction to disengage from the locking cavity 110, so as to realize the separation and unlocking of the locking part 100 and the movable part 200.

[0031] Furthermore, the locking rod 210 is provided with a locking protrusion 220, which is arranged around the circumference of the locking rod 210. The locking protrusion 220 and the locking rod 210 define a locking groove 230. The locking end 133 is provided with a locking block 134, which is suitable for being embedded in the locking groove 230 and abutting against the locking protrusion 220 to achieve the locking of the locking end 133 to the locking rod 210. In some preferred embodiments, the locking block 134 is also provided with a fitting groove 1343, and the shape of the fitting groove 1343 is adapted to the shape of the locking rod 210. Figure 3 In the illustrated embodiment, the fitting groove 1343 is arc-shaped, the locking rod 210 is cylindrical, and the arc radius of the fitting groove 1343 is the same as the arc radius of the locking rod 210. Therefore, when the locking block 134 is embedded in the locking groove 230, the locking block 134 can fit with the locking rod 210, further improving the locking reliability of the locking member 130 on the locking rod 210.

[0032] The locking block 134 includes a first locking surface 1341 and a first guide surface 1342, and the locking protrusion 220 includes a second locking surface 221 and a second guide surface 222. The first locking surface 1341 is perpendicular to the axis of the locking portion 100, and the second locking surface 221 is perpendicular to the axis of the locking rod 210, that is, the setting direction of the first locking surface 1341 and the second locking surface 221 is perpendicular to the moving direction of the locking rod 210. When the locking member 130 is in the locking position and the locking block 134 is embedded in the locking groove 230, the first locking surface 1341 of the locking block 134 and the second locking surface 221 of the locking protrusion 220 abut against each other, so that the locking rod 210 cannot slide in the direction of its axis, thereby realizing the locking of the locking portion 100 and the movable portion 200. The first guide surface 1342 is arranged obliquely, and the inclination direction of the first guide surface 1342 is toward the opening of the locking cavity 110. The second guide surface 222 is also arranged obliquely, and the inclination direction of the second guide surface 222 is the same as the inclination direction of the first guide surface 1342. When the locking rod 210 is inserted into the locking cavity 110, the second guide surface 222 on the locking protrusion 220 contacts the first guide surface 1342 on the locking block 134. Since the inclination directions of the first guide surface 1342 and the second guide surface 222 are toward the opening of the locking cavity 110, during the insertion process of the locking rod 210 When the locking rod 210 is inserted into a specific position, the locking block 134 automatically falls and is embedded in the locking groove 230, and the first locking surface 1341 of the locking block 134 abuts against the second locking surface 221 of the locking protrusion 220 to lock the locking rod 210. That is to say, when the user locks the locking part 100 with the movable part 200, he only needs to insert the locking rod 210 into the locking cavity 110, and there is no need to operate the pressing end 132 of the locking member 130.

[0033] In some embodiments, a return torsion spring 122 is disposed in the hinge seat 121 . When the external force acting on the pressing end 132 is removed, the return torsion spring 122 can return the locking member 130 to the locking position. One end of the return torsion spring 122 is installed on the hinge seat 121, and the other end of the return torsion spring 122 is installed on the shaft pin 131 of the locking piece 130. When the user presses the pressing end 132 of the locking piece 130, the locking piece 130 can drive one end of the return torsion spring 122 to rotate synchronously, and the tightened return torsion spring 122 will generate a force and act on the locking piece 130. The force is suitable for driving the locking piece 130 to rotate toward the locking position, so that after the external force acting on the pressing end 132 is removed, the locking piece 130 can return to the locking position under the action of the return torsion spring 122, that is, after the user releases the pressing end 132, the locking piece 130 can automatically reset to the locking position and keep the locking piece 130 in the locking position when the external force does not exceed the preset value.

[0034] A limit stopper 123 is provided in the installation groove 120, and the two ends of the limit stopper 123 are respectively connected to the groove walls on both sides of the installation groove 120. The limit stopper 123 is suitable for abutting against the locking member 130 to keep the locking member 130 in the locked position, and to limit the locking end 133 of the locking member 130 from further moving into the locking cavity 110 under the action of the return torsion spring 122. In addition, when the locking member 130 is in the locked position, the outer surface of the locking member 130 is integrated with the outer surface of the locking portion 100, thereby making the appearance of the locking structure more beautiful.

[0035] In other embodiments, the return torsion spring 122 is not provided in the hinge seat 121, but magnetic suction parts are provided on the limit stop block 123 and the locking end 133 respectively. Since the locking end 133 is provided with a locking stop block 134, the weight of the locking end 133 is greater than that of the pressing end 132. Therefore, when the user releases the pressing end 132, the locking end 133 will automatically fall under the action of its own gravity, so that the locking member 130 rotates to the locking position. When the locking member 130 rotates to the locking position, the limit stop block 123 and the magnetic suction parts on the locking end 133 attract each other, so that when the external force does not exceed the preset value, the locking member 130 can be kept in the locking position.

[0036] In some preferred embodiments, a pressing protrusion 1321 is further provided on the pressing end 132 of the locking member 130. For aesthetic reasons, the outer surface of the locking member 130 is usually arranged to be integrated with the outer surface of the locking portion 100. The pressing protrusion 1321 provided on the pressing end 132 of the locking member 130 allows the user to intuitively feel the pressing end 132, making it easier for the user to locate the pressing end 132 of the locking member 130.

[0037] The present application also provides a trekking pole, which comprises the above-mentioned locking structure.

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.
