For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0028] Please see Figures 1 to 10The utility model discloses a locking structure of a selfie stick, applied between a selfie stick body and a retractable support frame (20), characterized in that it comprises: a connecting part (10) fixedly arranged at the end of the selfie stick, which is rotatably connected with the support frame (20); a lock block structure (30) arranged on the connecting part (10), which comprises a main body (31) movable along a preset path; a locking part (40) arranged at the end of the support frame (20) and used for cooperating with the lock block structure (30) to lock or unlock the support frame (20); the main body (31) of the lock block structure (30) is provided with a first magnet (32) and a clamping convex (33); the locking part (40) is provided with a second magnet (41) and a friction surface (42); when the support frame (20) changes from an unfolded state to a folded state, the friction surface (42) of the locking part (40) contacts the clamping convex (33) of the lock block structure (30) and pushes the main body (31) to move until the first magnet (32) and the second magnet (41) are attracted to each other and adhere to each other, and at the same time, the clamping convex (33) abuts against the friction surface (42) to lock the support frame (20) in the folded state; when the support frame (20) changes from the folded state to the unfolded state, the clamping convex (33) is separated from the friction surface (42) by moving the main body (31), and the first magnet (32) is separated from the second magnet (41) to unlock the support frame (20).

[0029] In the embodiment, the connecting part (10) serves as a base connecting the selfie stick body and the support frame (20) and allows the support frame (20) to rotate relative to the selfie stick body in the folding and unfolding state. The lock block structure (30) is arranged in or attached to the connecting part (10), and the main body (31) is the core component, which is designed to slide or move along the up-down movement path of the connecting part (10). The locking part (40) is fixed at the end position of each support frame (20) that needs to be locked.

[0030] The locking process is as follows: when the user folds the support leg (20), the locking portion (40) on the support leg (20) moves. The outer friction surface (42) first contacts the clamping protrusion (33) on the main body (31) of the lock block structure (30). As the support leg (20) is further folded, the friction surface (42) exerts a pushing force on the clamping protrusion (33), causing the main body (31) to displace (move upward) against its own gravity or the pre-tightening force that may exist. When the main body (31) moves to a predetermined position, so that the first magnet (32) fixed thereon is close enough to the second magnet (41) fixed on the locking portion (40), the two will be quickly attracted to each other and adhere due to the magnetic force. This magnetic attraction not only assists the folding of the support leg (20) into place, but also provides preliminary positioning and retaining force. Then, due to the existing reset force, there will be a reverse tendency of resistance, so that the clamping protrusion (33) tightly abuts against the friction surface (42) of the locking portion (40), forming a mechanical lock, thereby stably locking the support leg (20) in the folded state. This combination of "magnetic attraction + mechanical clamping" ensures the reliability of the lock.

[0031] The unlocking process is the opposite: when the support leg (20) needs to be unfolded, the main body (31) is pressed to move in the opposite direction along the preset path. This movement causes the clamping protrusion (33) to first disengage from the friction surface (42), releasing the mechanical lock. At the same time, the movement of the main body (31) also increases the distance between the first magnet (32) and the second magnet (41), overcoming the magnetic attraction between them and causing them to separate. Once the mechanical lock and the magnetic lock are both released, the support leg (20) can be freely unfolded.

[0032] By guiding the movement of the main body (31) through the cooperation of the friction surface (42) and the clamping protrusion (33), combined with the automatic attraction of the magnets (32, 41) and the final abutment of the clamping protrusion (33) and the friction surface (42), smooth guidance, automatic positioning and attraction, and reliable locking of the support leg (20) during folding are achieved. By simply moving the main body (31), the double locking can be released, simplifying the unlocking operation. This effectively solves the problems of poor folding and easy jamming of existing selfie sticks, providing a more stable and convenient locking experience.

[0033] Please refer to Figures 1 to 10 , the lock block structure (30) further comprises a first limiting plate (34), a placement portion (35), and a second limiting plate (36) connected in sequence on the main body (31); the first magnet (32) is arranged on the placement portion (35), and the clamping protrusion (33) is arranged on the inner surface of the second limiting plate (36); the placement portion (35) is used to accommodate a part of the locking portion (40) when the support leg (20) is folded.

[0034] In this embodiment, the main body (31) is not a single structure, but is integrated or connected with the first limiting plate (34), the placement part (35) and the second limiting plate (36). These three parts can be understood as being arranged in sequence along the length direction of the main body (31) or other preset direction. The first magnet (32) is specifically fixed on or in the middle placement part (35). The clamping convex (33) is arranged on the inner side surface of the second limiting plate (36) facing the locking part (40). When the support frame (20) is folded, part of the locking part (40) (for example, the area containing the second magnet (41)) is guided and accommodated into the area or space formed by the placement part (35), so that the first magnet (32) and the second magnet (41) can be accurately aligned and attracted. In addition to the structural connection function, the first limiting plate (34) and the second limiting plate (36) can also play the role of guiding, limiting or cooperating with other parts.

[0035] This structure design makes the functional area of the locking block structure (30) more clear: the placement part (35) is mainly responsible for magnetic attraction and accommodation with the locking part (40); the second limiting plate (36) realizes mechanical locking through the clamping convex (33) thereon; and the first limiting plate (34) can be used for assisting the unlocking action. Such arrangement not only makes the structure more compact and orderly, but also is beneficial to the accurate implementation of each function, thereby improving the stability and working reliability of the locking block structure (30) as a whole.

[0036] Please refer to Figures 1 to 10 , the locking part (40) includes a fixed slot (43) and a friction surface (42) arranged on the outer side surface of the fixed slot (43); the second magnet (41) is embedded in the fixed slot (43); and the opening surface of the fixed slot (43) is an inclined surface (44).

[0037] In this embodiment, the locking part (40) includes a fixed slot (43), which is used for embedding and fixing the second magnet (41) to ensure the stability of the position of the second magnet (41). The friction surface (42) is arranged on the outer side surface of the fixed slot (43), that is, when the support frame (20) is folded, the friction surface (42) will come into contact with the clamping convex (33) of the locking block structure (30). A key structural feature is that the opening surface of the fixed slot (43) is designed as an inclined surface (44). When the main body (31) of the locking block structure (30) is pushed upward (as described above for the unlocking action), the edge of the first limiting plate (34) thereon will slide along the inclined surface (44). Due to the effect of the inclined surface (44), the upward force of the first limiting plate (34) will be partially converted into a transverse pushing force on the locking part (40), which actively pushes the locking part (40) (i.e., the end of the support frame (20)) outward.

[0038] The second magnet (41) is protected and fixed by the fixed slot (43), and the cooperation with the clamping convex (33) is realized by the friction surface (42) outside. More importantly, the introduction of the inclined surface (44) makes it not only release the lock, but also actively assist the initial unfolding action of the supporting leg (20) when unlocking, effectively avoiding the unfolding difficulty or jam caused by long-term storage or large friction between components, further improving the smoothness of operation.

[0039] Please see Figures 1 to 10 The connecting part (10) is provided with a guide column (11), and the guide column (11) is sleeved with a spring (12); the main body (31) is provided with a sliding hole (37) in sliding cooperation with the guide column (11); one end of the spring (12) abuts against the connecting part (10), and the other end abuts against the main body (31).

[0040] In this embodiment, one or more guide columns (11) are fixed on the connecting part (10). The main body (31) of the lock block structure (30) is provided with a sliding hole (37) matched with the guide column (11). The guide column (11) passes through the sliding hole (37), so that the main body (31) can stably slide along the direction of the guide column (11), ensuring the accuracy of the moving path of the main body (31). A spring (12) (usually a compression spring) is also sleeved on the guide column (11). One end of the spring (12) acts on a certain fixed point of the connecting part (10) (for example, the root of the guide column or the inner wall of the connecting part), and the other end acts on the main body (31) (for example, the edge of the sliding hole or a special spring seat on the main body).

[0041] The function of this spring (12) is: when the supporting leg (20) is folded, the friction surface (42) of the locking part (40) pushes the clamping convex (33) to move the main body (31) upward, the spring (12) is compressed, and the elastic potential energy is stored. After the first magnet (32) and the second magnet (41) are attracted, the compressed spring (12) releases the elastic force immediately, and pushes the main body (31) to reset downward (toward the locking part (40)). The resetting force makes the clamping convex (33) on the main body (31) tightly press and abut on the friction surface (42) of the locking part (40), thereby realizing the second mechanical pressure locking based on magnetic attraction, ensuring the firmness of the locking. When unlocking, the main body (31) is pressed upward, which also needs to overcome the elastic force of the spring (12).

[0042] This structure ensures the stability and accuracy of the movement of the main body (31) through the guide column (11) and the sliding hole (37), and provides the continuous pressure of the main body (31) to the downward abutting through the spring (12), which strengthens the locking effect and makes the whole locking structure more reliable and durable.

[0043] Please refer to Figures 1 to 10 The connecting part (10) is connected with the supporting leg (20) through a connecting rod (13), and a torsional spring (14) is arranged at one end of the connecting rod (13).

[0044] In the embodiment, the connecting mode of the connecting part (10) and the supporting leg (20) and the automatic unfolding function of the supporting leg (20) are further described. The connecting part (10) and each supporting leg (20) are rotatably connected through a connecting rod (13). The connecting rod (13) can be understood as a rotating shaft part of the supporting leg (20) or an independent connecting piece. The key is that a torsional spring (14) is arranged at one end of the connecting rod (13) close to the connecting part (10) (or at the rotating pivot thereof). The torsional spring (14) is twisted to store energy when the supporting leg (20) is in the folded state.

[0045] When the unlocking process is performed, the main body (31) is moved to separate the clamping convex (33) from the friction surface (42) and the first magnet (32) from the second magnet (41), that is, the constraint of the locking block structure (30) on the locking part (40) is released, and then the elastic potential energy stored in the torsional spring (14) is released. The restoring force of the torsional spring (14) drives the connecting rod (13) to rotate in the unfolding direction, thereby driving the supporting leg (20) to automatically rotate in the unfolding direction.

[0046] The arrangement of the torsional spring (14) enables the supporting leg (20) to automatically pop open to a certain extent after unlocking, so that the user does not need to manually separate each supporting leg (20) one by one, thereby greatly improving the operation convenience and response speed of the selfie stick from the folded state to the unfolded state, further improving the user experience, and solving the problem of insufficient smoothness in unfolding.

[0047] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the technical solution of the present application.
