[0069] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0070] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0071] like Figures 1 to 5 , which is a schematic diagram of various usage states of the posture corrector 100 of the utility model. The posture corrector 100 with a detachable connector provides an innovative solution, aiming to enhance the user's posture correction experience through its unique design. The corrector is particularly suitable for users who need to maintain or correct specific body postures in different postures and activities.

[0072] The posture corrector with a detachable connector includes a first stick 11 that can be used alone, a second stick 12 that can be used alone, and a connector 20. The design of the first stick 11 and the second stick 12 allows them to be used independently, providing flexibility and portability for users. When the user needs other forms of support or correction, the two sticks can be combined and used through the connector 20 to form a stable cross or parallel state to meet different posture correction needs.

[0073] The connector 20 includes two detachable connecting pieces 21, each of which is connected to a stick 10. A locking mechanism is provided between the two connecting pieces 21 to achieve locking or unlocking of the two connecting pieces. The locking mechanism allows the user to easily lock or unlock the connecting pieces as needed, thereby achieving quick connection and separation of the stick 10.

[0074] In the locked state, the two sticks 10 are connected and fastened in a cross state or a parallel state through the locking mechanism. In the unlocked state, the locking mechanism is unlocked, and the first and second sticks can be used separately.

[0075] In the cross state, the two sticks 10 are perpendicular to each other, providing the user with a comprehensive support frame, which helps to correct the spine and improve posture. In the parallel state, the two sticks 10 provide a stable horizontal or vertical support suitable for different corrective exercises and posture maintenance.

[0076] In the unlocked state, the easy-to-operate design of the locking mechanism allows the first stick 11 and the second stick 12 to be quickly separated, thereby allowing the user to flexibly use each stick separately according to different stages or needs of the activity. The above technical means not only improve the adaptability of the corrector, but also increase its portability, allowing the user to easily switch the usage mode in different scenarios.

[0077] The locking mechanism is preferably a plug-in structure 30 provided on the inner side (butt end face s) of the connector. This design allows the two detachable connectors 21 in the connector 20 to be connected or separated quickly and firmly without any additional tools or complicated operations.

[0078] Specifically, each connector 21 includes a body a1, and a cylindrical notch a2 with an open side on the back thereof is designed to tightly receive and fix the corresponding stick 10. The inner diameter of the cylindrical notch a2 is precisely matched with the outer diameter of the stick 10, ensuring the stability and reliability of the stick during use.

[0079] like Fig.10 and Fig.11 As described above, the curvature of the arc-shaped covering walls on both sides of the cylindrical notch a2 matches the curvature of the outer wall of the cylindrical stick, providing a tighter wrapping and stronger friction, ensuring that the stick 10 is firmly locked in the notch a2, and preventing sliding or displacement during use. The harmonious cooperation between the arc-shaped covering wall and the stick visually presents a smooth and unified aesthetic feeling, enhancing the overall aesthetics of the product. In addition, the design of the arc-shaped covering wall takes into account the manufacturing tolerance, ensuring that even if there are slight dimensional changes during the production process, it can maintain accurate and stable cooperation with the stick 10.

[0080] On the butt end faces s of the connectors 21, a carefully designed detachable concave-convex mating plug-in structure 30 realizes the rapid locking and fixation between the two connectors 21 through the exquisite cooperation between the convex portion 31 and the concave hole 32. When the two sticks 10 need to form a stable cross or parallel state, the butt end faces s of the two connectors 21 can be simply aligned to achieve a stable connection through the plug-in structure 30.

[0081] In addition, it should be noted that the design of the plug-in structure 30 allows the user to easily disengage the two sticks 10 by external force when necessary, so that the two sticks 10 can be quickly restored to a state of independent use. This feature greatly improves the flexibility and adaptability of the corrector, enabling it to meet the user's rapid switching in different occasions and different needs.

[0082] In addition, preferably, the design of the plug-in structure 30 takes into account the principle of ergonomics, ensuring the comfort and convenience of the user when performing the locking and unlocking operations. By optimizing the shape and size of the protrusion 31 and the recessed hole 32, the user can easily complete the locking and unlocking of the connector with one hand, and the operation can be kept smooth even when the corrector is subjected to a large force.

[0083] When the two sticks 10 are in a cross shape and / or parallel state, the butt end faces s of the two connectors 21 can be butted and fixed to each other through the plug-in structure 30. The precise matching of the protrusion 31 and the concave hole 32 provides a strong mechanical locking ability, so that the corrector can provide balanced support for the user in the cross-shaped use state, and can provide continuous support in the parallel state.

[0084] The plug-in structure 30 can be detached from each other under the external force of the user, and the two sticks 10 can be used independently. The disengagement mechanism of the plug-in structure 30 is designed to be very user-friendly. The user only needs to apply external force to separate the two connecting pieces 21, and easily achieve the transition from combined use to individual use. This feature greatly improves the practicality and flexibility of the corrector, allowing users to adjust the working state of the corrector at any time according to their own posture correction needs or daily use habits.

[0085] Preferably, the cross-sections of the first stick 11 and the second stick 12 are circular or quasi-circular in design. The circular cross-section stick provides a more natural grip, conforms to the principle of ergonomics, reduces the discomfort of the user's hand during use, and is suitable for long-term gripping and use.

[0086] Additionally, the round cross-section provides even support along the length of the stick, which helps to provide more effective posture correction, especially in applications where it is necessary to distribute force along the length of the stick. The round cross-section distributes pressure more evenly, which helps to improve the mechanical stability of the stick, making it more stable and reliable during correction.

[0087] In one case, the two connectors 21 include a first connector b1 and a second connector b2. The plug-in structure 30 includes at least one protrusion 31 on the butt end face s of the first connector b1 and at least one recessed hole 32 on the butt end face s of the second connector b2, and the protrusion 31 and the recessed hole 32 are plugged in by interference. The precise fit between the protrusion 31 and the recessed hole 32 ensures the reliability of the connection under high load and avoids potential safety risks caused by unstable connection. At this time, the two connectors 21 only need to be able to achieve the purpose of plugging and unplugging. Those skilled in the art can set the distribution of the protrusions and recessed holes as needed, and can also design other similar plug-in structures.

[0088] More specifically, the first connector b1 and the second connector b2 have the same structure. Connectors with the same structure simplify the production process because the same parts can be mass-produced, reducing manufacturing costs while ensuring consistency in product quality. In addition, since the two connectors have the same structure, they can be used interchangeably, increasing the flexibility of the corrector. Users can easily replace the connectors as needed without having to worry about left-right asymmetry.

[0089] A protrusion 31 and three recessed holes 32 for matching the protrusion 31 are provided on the butt end surface s of the connecting member 21. The protrusions 31 on the butt end surfaces s of the two connecting members 21 are respectively inserted into the recessed holes 32 to fix the positions of the first connecting member b1 and the second connecting member b2. The configuration of a protrusion 31 and three recessed holes 32 provides a stable mechanical lock, ensuring the precise alignment and fixation of the first stick 11 and the second stick 12 when used in combination.

[0090] In this case, one protrusion 31 and three recesses 32 are distributed in an equidistant square. The square-shaped protrusions 31 and recesses 32 take up less space, making the connector 21 more compact and easy to carry and store while maintaining a high-strength connection. In addition, the square-shaped distribution design is intuitive and easy to understand, and the user can easily identify the corresponding relationship between the protrusions 31 and the recesses 32, and can complete the assembly and adjustment of the stick without complicated instructions.

[0091] When the first stick 11 and the second stick 12 are in a cross shape, the protrusion 31 on the first connecting member b1 and the protrusion 31 on the second connecting member b2 are located at a diagonal position. The square distribution of the protrusion 31 and the recessed hole 32 provides a stable geometric frame. When the first stick 11 and the second stick 12 are combined into a cross shape, the protrusion 31 is located at a diagonal position, forming a solid X-shaped structure, which maximizes the stability of the structure.

[0092] When the first stick 11 and the second stick 12 are parallel, the protrusion 31 on the first connecting member b1 and the protrusion 31 on the second connecting member b2 are located at adjacent positions. When it is necessary to switch from the cross shape to the parallel state, the protrusion 31 can be quickly moved from the diagonal position to the adjacent position, and the design of the concave hole 32 ensures the simplicity and accuracy of the switching process.

[0093] The bottom of the cylindrical notch a2 to the butt end face s has a certain thickness, so that there is a certain gap between the two sticks 10, and the gap range is 3mm-12mm. It should be noted that the thickness from the bottom of the cylindrical notch a2 to the butt end face s can be set smaller to save the occupied space if the process allows, and the space occupied by the two sticks after closing is smaller.

[0094] The material of the stick 10 is wood, plastic or metal to meet the needs of different user preferences and usage environments. The wooden stick is warm and has a good texture, the plastic stick is light and cost-effective, and the metal stick provides additional strength and durability.

[0095] Silicone sleeves are provided at both ends of the stick 10. The silicone sleeve design at both ends of the stick 10 not only increases the comfort when holding, but also provides a good anti-slip effect, so that the user can hold it firmly even when the hands are sweaty or slippery.

[0096] The material of the first connector b1 and / or the second connector b2 is silicone. The wear and tear resistance of silicone means that the connector can maintain its structural integrity during long-term use and is not easily damaged. In addition, the silicone material can absorb impact force, and the silicone connector can reduce the noise generated by friction and impact during use, thereby ensuring the service life of such components that need to be frequently released and locked.

[0097] The posture corrector 100 has achieved a major technological breakthrough through its innovative connector 20 setting, allowing the user to flexibly choose to use a single stick or a double stick cross-shaped combination according to the specific needs of posture correction. In the single-stick use mode, the first stick 11 or the second stick 12 can independently provide support or correction for a part of the body, which is easy to carry and store, while reducing space occupancy, and is suitable for use in environments that require local correction or are space-constrained. In the double-stick cross-shaped combination use mode, the two sticks are fixed into a stable cross-shaped structure through the locking mechanism of the connector 20, providing users with whole-body support and correction, which is particularly suitable for use when all-round correction is required or when performing complex posture training.

[0098] In addition, the plug-in structure 30 of the connector 20 adopts the precise matching of the protrusion 31 and the recessed hole 32, which not only ensures the stability and firmness of the double-stick cross-shaped combination, but also makes the unlocking and disengagement process simple and quick, and can be easily achieved without additional tools, greatly improving the user experience.
