Description

Technical Field

[0001] This patent relates to the field of orthotics, specifically to a quick-assembly and disassembly structure for a sitting posture corrector. Background Technology

[0002] With increasing societal concern about the vision health and spinal morphology of teenagers, and the urgent need for ergonomic design in modern office settings, posture correction desks and their accompanying reading racks have evolved from peripheral aids into core components of healthy learning and working environments. The fundamental purpose of these products is to guide users to maintain a scientific viewing distance and reading angle through physical constraints, forcing them into a correct ergonomic posture, thereby effectively preventing and alleviating myopia, cervical spine, and related spinal diseases at their root. Within this functional logic, the reading rack, as a key component directly supporting books, tablets, and other reading media, directly determines the effectiveness of the correction and the quality of the user experience through the structural performance of its connection with the main tabletop.

[0003] In practical applications, users' needs for reading racks are highly dynamic and scenario-based. For example, when writing, drawing, or using a keyboard, the reading rack needs to be completely removed to obtain a complete and flat desktop operating space; while when switching to reading mode, it needs to be quickly and accurately reset to a comfortable viewing angle. This high-frequency switching between "flexible storage" and "stable support" places extremely high demands on the convenience and reliability of the connection structure. However, the mainstream technical solutions currently on the market, such as integrated fixing, snap-fit ​​fixing, and screw fixing, all have insurmountable systemic defects. Integrated structures permanently occupy space, deviating from the core requirement of flexibility; while common snap-fit ​​designs can achieve easy assembly and disassembly, they are prone to structural fatigue under cyclic loads, leading to loose connections, shaking and abnormal noises, or even accidental detachment, resulting in serious reliability deficiencies; and while screw locking solutions can provide reliable connection strength, their assembly and disassembly process is cumbersome and relies on special tools, completely failing to meet the basic user expectation of "speed". Therefore, this field has long faced a sharp technical contradiction: how to achieve rapid assembly and disassembly operations that can be completed with one hand without tools, while ensuring that the connecting mechanism has excellent stability and anti-shaking ability under load. Developing a new quick-release structure that can fundamentally reconcile this contradiction has become an urgent technical challenge driving the development of this field. Utility Model Content

[0004] The purpose of this patent is to provide a quick-release structure for a reading rack, addressing the problems of existing connection structures that commonly infringe on desktop space, are cumbersome to assemble and disassemble, and have poor connection stability. This invention, through a quick-assembly and disassembly structure, ensures a stable and reliable connection while achieving rapid assembly and disassembly.

[0005] To solve the above-mentioned technical problems, this patent adopts the following technical solution:

[0006] A quick-assembly and disassembly structure for a posture corrector is provided for tool-free quick assembly and disassembly between a posture corrector table and a reading frame. The posture corrector table has a receiving groove, in which a first receiving part and a second receiving part are provided. The bottom of the reading frame has a connecting seat, on which a first connecting part and a second connecting part are respectively provided to cooperate with the first receiving part and the second receiving part. The first connecting part is axially movable on the connecting seat and has an outwardly protruding initial position driven by a reset member. The quick-assembly and disassembly structure includes the following assembly states: The quick-assembly and disassembly structure has an assembly preparation state: In this state, the first connecting part is pressed and retracted and passes through the first receiving part, and the axes of the second connecting part and the second receiving part are offset from each other and there is no end-face interference between them; The quick-assembly and disassembly structure also has an assembly locking state: In this state, the first connecting part is located in the initial position under the action of the reset member, and the second connecting part is axially aligned with the second receiving part and inserted into the second receiving part.

[0007] Furthermore, the reset element is a spring.

[0008] Furthermore, the first connecting part is a telescopic pin, which is slidably disposed in the slide groove, and a spring acts on the telescopic pin.

[0009] Furthermore, the bottom of the reading rack is provided with at least one safety slot.

[0010] Furthermore, the receiving groove is provided with a limiting boss that cooperates with the safety groove.

[0011] Furthermore, in the assembled and locked state, the limiting boss engages with the safety groove.

[0012] Furthermore, the outline of the safety groove includes a guide section and a locking section.

[0013] Furthermore, the width of the guide section gradually decreases along the installation direction to guide the limiting boss into the safety groove during the transition from the assembly preparation state to the assembly locking state.

[0014] Furthermore, the width of the locking section gradually widens at least partly along the installation direction to form surface contact with the limiting boss in the assembled locked state.

[0015] Furthermore, both the first positioning part and the second positioning part are countersunk hole structures.

[0016] Furthermore, the second connecting part is a fixed pin structure.

[0017] Furthermore, the surface of the posture correction table is covered with a non-slip surface.

[0018] Furthermore, the main body of the reading rack can be made of lightweight, high-strength engineering plastics or aluminum alloy.

[0019] Furthermore, the receiving tank is a multi-functional tank.

[0020] Furthermore, when the reading rack is not installed, the limiting boss is used to block the edge of the tablet or book placed in the multi-functional slot to prevent it from sliding out.

[0021] This patent provides a quick-assembly and disassembly structure for a posture corrector, which has the following advantages compared to the prior art:

[0022] First, it achieves efficient one-handed, tool-free operation: through the ingenious cooperation of the retractable first connecting part and the reset element, the user only needs to perform a single continuous action of "press-rotate-release" to complete the installation. The process is smooth and intuitive, greatly improving ease of use and efficiency. Second, the connection is stable and reliable with multi-directional self-locking capability: in the assembled and locked state, the second connecting part automatically embeds into the second receiving part under the drive of the reset force, forming an axial rigid connection; at the same time, the safety groove at the bottom of the reading rack and the limiting boss in the receiving groove tightly engage, forming a surface contact constraint, effectively suppressing lateral and longitudinal swaying, ensuring that the reading rack remains stable when carrying books. In addition, this structure achieves functional integration and space reuse: the receiving groove and its internal limiting boss, without adding any parts, not only provide a limit for the reading rack, but can also be used as a storage space for tablets or books after the reading rack is removed. The same limiting boss prevents items from slipping, achieving two uses in one, saving space and cost. Moreover, the design of the stop provides a reliable abutment for the first connection part during the assembly preparation stage, preventing components from accidentally coming off and ensuring the accuracy of the installation path and the fault tolerance of the operation process.

[0023] In summary, through the synergistic effect of its components, this structure allows users to safely, quickly, and stably assemble and disassemble the reading rack using only a simple "press-rotate-release" operation, depending on changes in learning or work scenarios, significantly enhancing the product's practicality and user experience.

Therefore, any equivalent transformation of the orientation or position of components based on the essential concept of this invention should be included within the scope of protection of the claims of this patent.

[0065] The design of this quick-release structure stems directly from the core pain points that were not addressed by the target users in actual usage scenarios. For the core user group of the posture correction platform—teenagers and office workers who need to work at their desks for long periods of time—their learning and workflow naturally involves frequent and rapid switching between "reading" and "writing" modes. When reading, the reading stand 200 needs to be adjusted to a suitable angle to place books or tablets; while when writing or using a computer, there is an urgent need to move the reading stand 200 away from the front of the field of vision or place it to the side with minimal space occupation to free up a sufficient and flat desktop work area. Therefore, there is an urgent need for a connection solution that can be quickly assembled and disassembled with one hand and without tools, and that can provide stable and anti-shake support after installation.

[0066] See Figures 1-4 The reading rack 200 is mainly used to support items such as books or tablet computers. Its bottom includes a connecting base 210. Specifically, the connecting base 210 has an axially extendable first connecting portion 211, which in this embodiment is a telescopic pin. Inside, there is a reset member 214, which is a compression spring. The reset member 214 drives the first connecting portion 211 to always have an outward extension tendency, providing the power for automatic locking. The first connecting portion 211 can slide in a groove 215 formed within the connecting base 210. A second connecting portion 212 is located at the other end of the first connecting portion 211. Specifically, this component in this embodiment is a fixed pin, and its position relative to the connecting base 210 remains fixed. To ensure stability after connection, at least one safety groove 213 is also machined on the bottom of the reading rack 200.

[0067] See Figure 13The safety groove 213 is designed as an irregularly shaped groove containing a guide section 213a and a locking section 213b along the installation direction. The installation direction refers to the direction of movement of the limiting boss 113 relative to the safety groove 213 during the installation of the reading holder onto the posture correction platform, i.e., the direction from the bottom upwards of the safety groove 213. The width of the guide section 213a gradually narrows upwards from the bottom, forming a guiding slope. This structure allows the reading holder 200 to first contact the limiting boss 113 during the transition from the assembly preparation state to the assembly locking state, and uses its tapering sidewalls to guide the limiting boss 113 smoothly into the groove, providing initial centering and forced guidance, effectively reducing assembly difficulty and preventing jamming. Following the guide section 213a is the locking section 213b, whose groove width gradually widens. When the limiting boss 113 slides into this section under the drive of the reset member 214, the front wall surface of the locking section 213b forms a tight surface contact with the side wall of the limiting boss 113. This effectively resists forces and torques in multiple directions, thereby enhancing the stability of multiple degrees of freedom. Preferably, there are six locking grooves 213, evenly distributed on the connecting seat.

[0068] The main body of the reading holder 200 can be made of lightweight, high-strength engineering plastics (such as ABS, PC) or aluminum alloy through injection molding or die casting. Its book-holding mechanism (not shown in the figure) can be a conventional spring clip or screw adjustment mechanism, which is a technology well known to those skilled in the art and will not be described in detail here.

[0069] The posture correction platform 100 serves as the base of the device, and its surface is provided with a receiving groove 110. The receiving groove 110 includes a first receiving part 111 for accommodating the first connecting part 211 and a second receiving part 112 for accommodating the second connecting part 212. At least one limiting boss 113 is also provided in the groove, which can match the safety groove 213 on the reading rack 200. When the two are engaged, they can form a surface contact constraint to prevent lateral swaying. In addition, a stop part 114 is provided inside the first receiving part 111. The stop part 114 abuts against the end of the first connecting part 211 during the initial installation, serving as a fulcrum for rotation and preventing the component from accidentally falling out.

[0070] The surface of the posture correction table 100 can be coated with an anti-slip coating or have an anti-slip mat applied to increase the stability when books are placed on it. More importantly, the entire surface or the receiving slot 110 itself can be designed with a slight tilt angle of 3 to 15 degrees. This ergonomic design guides users to adopt a healthier downward reading posture, thereby effectively relieving cervical spine pressure. The base material can be solid wood, MDF, or plastic to meet different cost and texture requirements.

[0071] See Figures 6 to 8The design of the receiving slot 110 in this embodiment embodies a high degree of functional integration. The receiving slot 110 not only serves as the mounting base for the reading rack 200, but it can also function as a temporary storage space for tablets or books, achieving functional reuse. In addition to its function as an extension space, specifically, when the reading rack 200 is not installed, the receiving slot 110 can independently function as a storage space for directly placing peripherals 800, such as tablets, smartphones, or books. In this application scenario, the limiting protrusion 113 within the slot acts as a raised barrier structure, effectively blocking the bottom edge of the placed item and preventing it from tipping over or sliding out of the slot due to slight contact with the surface or its own weight, greatly improving safety and convenience. The receiving slot 110 achieves "one slot, multiple uses": when installing the reading rack, it enables precise positioning and anti-shake locking; when used independently, it forms a safe storage space. This ingenious multi-functional integrated design significantly improves the product's practicality and user experience without adding any extra parts, while saving production and space costs.

[0072] Quick disassembly and assembly process

[0073] As attached Figure 9 As shown, at the start of installation, the user holds the reading stand 200 and moves the connecting seat 210 to the vicinity of the receiving slot 110 above the posture correction table 100 in preparation for assembly.

[0074] As attached Figure 10 As shown, the reading holder 200 is first tilted to the left at an angle. Then, the first connecting part 211 on the connecting seat 210 is aligned and passes through the first receiving part 111 on the receiving groove 110. During this process, a leftward thrust along the axial direction of the first connecting part 211 is applied to the reading holder 200, causing the end of the first connecting part 211 to abut against the stop part 114 in the receiving groove 110. This thrust overcomes the elasticity of the reset member 214, forcing the first connecting part 211 to retract inward and partially retract into the slide groove 215. At the same time, due to the tilt angle, the entrance of the safety groove 213 at the bottom of the reading holder 200 is spatially misaligned with the limiting boss 113 in the receiving groove 110, making way for subsequent rotation. At this time, the reading holder 200 is in the assembly preparation state.

[0075] As attached Figure 11As shown, while maintaining the pressing state of the first connecting part 211, using the contact point between the first connecting part 211 and the stop part 114 as a fulcrum, rotate the right end of the reading holder 200 clockwise so that the connecting seat 210 is stably placed into the receiving groove 110. During this rotation, since the reading holder 200 has already shifted to the left as a whole, the end faces of the second connecting part 212 on it and the second receiving part 112 on the receiving groove 110 are offset from each other. The end of the second connecting part 212 will not interfere with the groove wall of the receiving groove 110 or the hole edge of the second receiving part 112, thus ensuring the smooth operation of the rotation. At the same time, during the rotation, the limiting boss 113 gradually enters the safety groove 213 along the guide section 213a of the safety groove 213 until it is completely slid into the locking section 213b.

[0076] As attached Figure 12 As shown, when the reading holder 200 is rotated until the second connecting part 212 at its bottom and the second receiving part 112 are fully aligned axially, the thrust applied to the reading holder 200 is released. At this time, the compressed reset member 214 instantly releases its elastic potential energy, driving the first connecting part 211 to extend outward, and simultaneously pushing the entire reading holder 200 to translate to the right relative to the posture correction platform 100. This translation synchronously drives the locking groove 213 to move to the right, so that the front end face of its locking section can interfere with the limiting boss 113, forming a tight surface contact. At the same time, the second connecting part 212 is precisely inserted into the second receiving part 112 under the translation. Thus, through the insertion of the second connecting part 212 and the second receiving part 112 and the engagement of the locking groove 213 and the limiting boss 113, double locking is achieved, and the reading holder 200 enters a stable assembly and locking state, completing the installation.

[0077] The disassembly process of the reading rack:

[0078] The disassembly process is the reverse of the installation process. The user applies a leftward pushing force to the reading holder 200, overcoming the elastic force of the reset member 214, causing the reading holder 200 to translate to the left. This action first disengages the locking section of the safety groove 213 from the limiting boss 113, releasing the surface contact constraint. At the same time, the second connecting part 212 retracts from the second receiving part 112, and the two no longer interfere with each other. Subsequently, the right end of the reading holder 200 can be lifted upward and rotated counterclockwise, and then the first connecting part 211 can be pulled out from the first receiving part 111, finally completely removing the reading holder 200.

[0079] Industrial application

[0080] Compared with existing technologies, the quick-release structure provided by this utility model brings significant and multifaceted technical effects through its unique mechanical structure and the synergistic effect between components, specifically reflected in:

[0081] 1. Improved ease of use and user experience

[0082] This invention completely overturns the traditional screw-fixing or complex buckle operation logic, introducing a "press-rotate-release" one-handed operation mode. Users can install or disassemble the reading holder in seconds with just one hand, without any tools, making the process smooth and ergonomic. This convenience perfectly meets the core need of users who frequently switch between "reading" and "writing" modes during study and work, eliminating obstacles and interruptions in the usage process, and greatly increasing the product's usage frequency and user satisfaction.

[0083] 2. The fundamental guarantee of connection stability and reliability

[0084] This invention ensures stability in the connected state through a multi-layered locking mechanism. Driven by the reset component, the second connecting part inserts into the second receiving part, forming a multi-degree-of-freedom limiting position, effectively preventing the reading holder from accidentally tilting or falling off. Furthermore, the cooperation between the safety groove and the limiting boss utilizes the structure's self-locking effect to create a multi-directional anti-shake design. When subjected to reverse tension, the structure tightens further, fundamentally eliminating shaking and abnormal noise when carrying books, with stability far exceeding traditional point-contact or line-contact latches.

[0085] 3. A delicate balance between structural optimization and cost control

[0086] The receiving slot and its internal limiting bosses serve multiple functions. When installing a reading rack, they act as positioning and locking mechanisms; when used independently, they together form a secure storage compartment. This design significantly expands product functionality without adding any extra parts. The entire quick-release structure consists of a small number of well-developed components (such as pins, springs, and injection-molded parts), eliminating the need for complex or expensive special parts. This not only reduces manufacturing costs but also simplifies the assembly process, improves production efficiency, and offers high economic efficiency and market competitiveness.

[0087] 4. Comprehensive enhancement of safety protection and guidance functions

[0088] Anti-slip and anti-misoperation: The stop design provides a clear abutment point for the first connection part during initial installation, preventing parts from slipping due to improper force during rotation, ensuring the correctness of the installation path and operational safety. Smooth guidance: The guide section of the safety groove, with its tapering slope design, automatically guides the limiting boss into the correct position, reducing assembly difficulty, increasing the error tolerance, and ensuring easy installation every time.

[0089] 5. Expanding the scope of product practicality

[0090] Improved space utilization: The quick assembly and disassembly capabilities allow users to free up desktop space at will, meeting the urgent need for efficient space utilization in modern compact learning and office environments, and greatly enhancing the product's practicality.

[0091] In summary, this utility model is a comprehensive solution that integrates convenient operation, superior stability, economic cost, safety, reliability, and health benefits. It has significant technical effects and broad market prospects.
