Abstract
Description
Technical Field
[0001] This patent relates to ergonomic office supplies, specifically a locking mechanism for quick-release components. Background Technology
[0002] In recent years, myopia prevention and spinal health issues among children and adolescents have received considerable attention. Posture correctors, as an effective assistive tool, help users maintain an appropriate distance between their eyes and books and correct posture through physical restraint, playing a significant role in preventing and delaying myopia progression and cultivating good posture. As one of its core extended functional components, reading stands, though often optional accessories, can support books at a suitable angle and height, further reducing neck and visual fatigue, thereby improving overall usability and user experience. To accommodate books of different sizes, diverse learning tasks (such as reading, writing, and drawing), and facilitate storage and organization, designing reading stands that can be detachably connected to the main body via quick-release components has become a common requirement for improving product applicability and market appeal.
[0003] Currently, common quick-release components for achieving this type of detachable connection mainly include threaded fasteners, snap-fit fasteners, and movable pin fasteners, but all of them have significant drawbacks. Threaded fasteners (such as screw connections) provide a secure connection, but disassembly and assembly require tools, making the process cumbersome, and small parts are easily lost. Snap-fit fasteners allow for quick assembly and disassembly, but their snap-fit structure is prone to failure due to material fatigue after prolonged and frequent use, leading to loosening of the connection. The most relevant movable pin connection, while balancing stability and mobility well, typically includes additional parts such as a pin, spring, and a separate end cap or nut for securing the spring. This results in a large number of components, complex assembly processes, high production costs, and the additional fasteners themselves can become potential points of failure.
[0004] Therefore, there is an urgent need for a locking mechanism that is structurally simplified, requires no auxiliary tools or independent fasteners, enables reliable and quick assembly and disassembly, and is easy to manufacture. This locking mechanism can reliably assemble the quick-release mechanism. Utility Model Content
[0005] The purpose of this patent is to provide a locking mechanism for quick-release components to solve the technical problems of existing movable pin structures having many parts, complex assembly, and the need for additional fasteners.
[0006] To solve the above-mentioned technical problems, this patent adopts the following technical solution:
[0007] A locking mechanism for a quick-release assembly includes: a support base, a quick-release latch, and a biasing member disposed between the two; wherein: the support base has a receiving hole and a guide groove radially communicating with the receiving hole, and the width of the guide groove is smaller than the diameter of the receiving hole; the quick-release latch is integrally formed, including a main body, and a clearance structure and a limiting structure arranged sequentially along the axial direction of the main body, the clearance structure being able to align with the guide groove so that the quick-release latch enters the receiving hole radially, and after the quick-release latch rotates and / or moves axially, it is misaligned with the guide groove to form a radial limit; the biasing member is clamped between the quick-release latch and the support base to apply an axial biasing force to the quick-release latch.
[0008] Furthermore, an inlet groove is formed at the top of the receiving hole.
[0009] Furthermore, the avoidance structure is composed of at least one plane formed by radially inward cutting from the outer wall of the main body.
[0010] Furthermore, the limiting structure is an annular shoulder formed on the main body, and the outer diameter of the shoulder is larger than the diameter of the receiving hole.
[0011] Furthermore, the biasing element is a compression spring.
[0012] Furthermore, the bearing base is provided with an abutment block for accommodating and positioning one end of the biasing component.
[0013] Furthermore, the main body of the quick-release latch is a cylinder, and the clearance structure consists of two parallel planes symmetrically machined on the cylinder.
[0014] Furthermore, one end of the biasing component abuts against the inner cavity of the bearing base, and the other end abuts against the limiting structure of the quick-release latch.
[0015] Furthermore, the supporting substrate also integrally extends a fixed shaft head on the side opposite to the receiving hole, and the axis of the fixed shaft head is collinear with the axis of the receiving hole.
[0016] This patent provides a locking mechanism for quick-release components, which has the following advantages over the prior art:
[0017] This design integrates multiple discrete components (such as the pin, spring, independent end cap, and screw) in a traditional movable pin structure into a streamlined system consisting of a load-bearing base, a one-piece quick-release latch, and a biasing component. Through the cooperation of a "guide groove with a width smaller than the bore diameter" on the load-bearing base and a "pass-through clearance structure" on the quick-release latch, a mechanical state transition between the "installed position" and the "locked position" is cleverly achieved solely through axial movement and rotation. This design eliminates reliance on external fasteners, thereby reducing the total number of parts, simplifying the assembly process, helping to reduce material and assembly costs, and improving the long-term reliability of the mechanism under frequent disassembly and assembly. From a user experience perspective, this structure allows the reading rack to be locked and disassembled by hand without tools, making operation more convenient and safer. From a product perspective, the simplified structure also brings greater flexibility to the overall design, enhancing the product's practical value and market competitiveness in a more cost-effective manner.

[0051] Combination Figures 1 to 6 As shown, this embodiment provides a locking mechanism for a quick-release assembly, wherein the quick-release assembly is used to establish a mechanical connection between the posture corrector body and accessories such as reading frames that can be completed quickly and without tool dependence. The support base 1 is fixed to the posture corrector body and forms a through-hole-groove composite channel along the thickness direction. The quick-release latch 2 is an integrally injection-molded plastic part that can be axially moved through the channel. Its outer end protrudes from the support base 1 for finger gripping, and the inner end is fitted with a biasing member 3. The two ends abut against the latch shoulder and the inner wall of the base respectively, continuously outputting an elastic biasing force that tends the quick-release latch 2 towards the outside. When the user pushes and rotates the quick-release latch 2 with one hand, its clearance structure and guide groove switch between the "alignment-misalignment" two states to achieve radial locking or release, thereby enabling the accessory to quickly switch between the "locked" and "released" states and complete the quick-release operation.
[0052] like Figure 1 , Figure 2 and Figure 5 As shown, the supporting base 1 constitutes the fixed base and outer shell of the entire locking mechanism. It is typically integrally molded from engineering plastics (such as ABS, PC, or nylon) with a certain strength and rigidity through injection molding to ensure structural integrity and dimensional accuracy. Figure 2 As shown, the main structure of the support base 1 is a box-shaped mounting cavity with an opening at the top. Multiple ribs perpendicular to the axial direction are provided within the mounting cavity. The different structures on the ribs support and position the quick-release latch 2. A horizontal shaft hole 11 is provided on one side of the support base 1. Inside the mounting cavity, a receiving hole 12 is provided, coaxial with the shaft hole 11 and having a substantially uniform inner diameter. The receiving hole 12 and the shaft hole 11 together form a continuous, uniformly sized through channel for the reciprocating movement of the main body 21 of the quick-release latch 2. An integrally formed guide groove 14 (such as...) is formed at the top of the receiving hole 12. Figure 3(As shown in the enlarged view at point A). The guide groove 14 extends from the inner circumference of the receiving hole 12 towards the top of the mounting cavity, and the width of the guide groove 14 is designed to be slightly smaller than the diameter of the receiving hole 12. Furthermore, inside the mounting cavity, there is an abutment block 13 for providing abutment for the biasing member 3, providing a stable axial abutment surface for the biasing member 3. On the other side of the shaft hole 11, i.e., the side opposite to the quick-release latch 2, a fixed shaft head 15 extends integrally from the support base 1. The axis of the fixed shaft head 15 is collinear with the axes of the shaft hole 11 and the receiving hole 12, and its outer diameter is slightly smaller than that of the shaft hole 11. The fixed shaft head 15 serves as a hinge or support point for the other end of accessories such as reading shelves and book clips, and together with the quick-release latch 2, achieves the positioning and locking of the two points of the accessory.
[0053] A mounting part 16 is designed on the bottom outer side of the support base 1. The mounting part 16 can be a flange platform with multiple screw holes, a standard snap-fit structure, or a preset adhesive surface. Its purpose is to securely and reliably install the entire support base 1 onto the predetermined position of the frame or panel of the main product such as a posture corrector or study desk.
[0054] The quick-release latch 2 is preferably made of wear-resistant engineering plastic (such as POM or fiber-reinforced nylon) through injection molding to ensure structural strength, dimensional stability, and reduce the coefficient of friction. Figure 4 As shown, the quick-release latch 2 includes a main body 21, which, along its axial direction, comprises: an aligning member 24 for positioning the biasing component, a limiting structure 23, a clearance structure 22, and an operating part 25. The main body 21 is cylindrical in shape, with a diameter that can slide with the receiving hole 12. The clearance structure 22 consists of two symmetrical parallel planes formed by radially cutting inward from the cylindrical surface of the main body 21, the spacing of which matches the width of the guide groove 14. The limiting structure 23 is an annular shoulder with an outer diameter larger than the diameter of the receiving hole 12, used for axial limiting. The aligning member 24 is used to fit the inner end of the biasing component 3 and provide precise axial positioning for the biasing component 3. The operating part 25 is located at the outermost end of the quick-release latch 2, and after assembly, part of it is exposed in the shaft hole 11 of the bearing base 1 for user pressing operation.
[0055] In this embodiment, the aligning member 24 is located at the far end of the quick-release latch 2, and is cylindrical or a column with a limiting protrusion. Its diameter is smaller than that of the main body 21. It is specifically used to fit and position the inner end of the biasing member 3 (such as a spring), preventing the spring from radially shifting during compression or extension and ensuring axial transmission of force. The limiting structure 23 is adjacent to the aligning member 24 and is an annular shoulder with a diameter significantly larger than that of the main body 21. The outer diameter of this shoulder structure is designed to be larger than the diameter of the receiving hole 12 of the bearing base 1, but smaller than the internal space dimension of the mounting cavity. One of its core functions is that when the quick-release latch 2 moves outward under the action of the biasing member 3, the end face of the limiting structure 23 will abut against the inner end of the receiving hole 12 (i.e., the end near the fixed shaft head 15). This interference design limits the maximum outward extension stroke of the quick-release latch 2, preventing it from accidentally disengaging due to spring force.
[0056] The main body 21 is a cylindrical rod connecting the limiting structure 23 and the operating part 25. Its diameter slides into the receiving hole 12 of the bearing base 1, ensuring smooth and stable axial movement of the quick-release latch 2. The clearance structure 22 consists of two symmetrical parallel planes formed by radially cutting (or directly injection molding) from the cylindrical surface of the main body 21. The distance between these two planes matches the width of the guide groove 14 on the bearing base 1. This design allows the clearance structure 22 to pass through the guide groove 14 only under specific orientations, which is key to achieving radial installation or removal of the quick-release latch 2. The operating part 25 is located at the outermost end of the quick-release latch 2. In the assembled state, a portion of the operating part 25 is always exposed outside the shaft hole 11 of the bearing base 1, providing a clear point of force for the user or bookshelf installation position for pressing operations.
[0057] In this embodiment, the biasing element 3 is a compression coil spring. The biasing element 3 is sleeved on the alignment element 24, with one end abutting against the limiting structure 23 of the quick-release latch 2 and the other end abutting against the abutting block 13 inside the bearing base 1, thereby always applying an outward pushing force to the quick-release latch 2, so that its operating part 25 tends to be exposed.
[0058] Assembly process
[0059] Combination Figures 7 to 10 Instructions on how the quick-release latch 2 can be easily installed without the need for additional fasteners:
[0060] During assembly, first hold the quick-release latch 2 in its specific "assembly orientation," that is, ensure that the clearance structure 22 on it is completely aligned in space with the guide groove 14 on the support base 1. Since the contour (width between the two planes) of the clearance structure 22 is adapted to the width of the guide groove 14, and the width of the guide groove 14 is smaller than the diameter of the receiving hole 12, if the clearance structure 22 is not aligned with the guide groove 14, the body 21 of the quick-release latch 2 cannot enter the receiving hole 12 with its complete cylindrical surface.
[0061] In the aforementioned alignment state, the quick-release latch 2 is moved along the extension direction of the guide groove 14 (i.e., radially perpendicular to the axis), allowing the clearance structure 22 to pass through the guide groove 14 first and enter the internal space of the support base 1. The quick-release latch 2 is then placed radially downwards, with its main body 21's cylindrical surface sliding entirely into the receiving hole 12 of the support base 1. Throughout the insertion process, the clearance structure 22 remains within the space of the guide groove 14; this is the only path for the quick-release latch 2 to enter the support base 1.
[0062] Once the quick-release latch 2 is fully inserted into the receiving hole 12, rotating the quick-release latch 2 (e.g., rotating it approximately 90 degrees) and / or moving it axially will completely disengage the clearance structure 22 from the guide groove 14 in the circumferential and / or axial directions. This operation ensures that the complete cylindrical surface of the body 21 of the quick-release latch 2 forms full circumferential contact with the inner wall of the receiving hole 12.
[0063] Finally, the quick-release latch is moved axially to make room for the installation of the biasing member 3 (compression coil spring). The biasing member 3 is then compressed and fitted onto the aligning member 24 of the quick-release latch 2, and placed into the internal cavity of the support base 1. One end of the biasing member 3 abuts against the limiting structure 23 of the quick-release latch 2, and the other end abuts against the abutting block 13 of the support base 1. The preload of the spring forces the quick-release latch 2 to move slightly axially outward until its limiting structure 23 abuts against the side wall of the receiving hole 12, thereby preventing it from disengaging. At this point, since the avoidance structure 22 is misaligned with the guide groove 14 and the cylindrical surface of the main body 21 is in contact with the receiving hole 12, the quick-release latch 2 is completely constrained radially and can only extend and retract axially against the biasing force of the biasing member 3. Because the limiting structure 23 on the quick-release latch is larger than the receiving hole 12, it limits the outward travel of the quick-release latch relative to the bearing base 1 along the axial direction when it abuts against the receiving hole 12. This achieves locking of the quick-release structure.
[0064] This assembly process utilizes the guide groove 14, whose width is smaller than the aperture, and the contour-matching avoidance structure 22 to create a "directional assembly path". During assembly, alignment is achieved, and during use, slight positional disturbances can achieve misalignment and locking. Thus, the most simple structure achieves reliable limiting of the movable pin, completely eliminating the need for independent fasteners such as end caps and screws required in traditional structures.
[0065] Optionally, to further enhance the structural rigidity of the support base 1 and ensure the movement accuracy of the quick-release latch 2, one or more reinforcing ribs may be provided in the area between the shaft hole 11 and the receiving hole 12. These ribs are configured to include holes arranged coaxially with the shaft hole 11 and the receiving hole 12, with the side facing the top of the mounting cavity remaining open. This configuration provides additional radial support for the quick-release latch 2 body 21 passing through the hole, preventing it from deflecting due to excessive cantilever length, while also ensuring the strength of the injection mold.
[0066] The process of assembling the locked quick-release assembly with the reading rack accessory.
[0067] Reading rack installation:
[0068] Once the locking mechanism has locked the latch, forming a usable quick-release assembly, for applications requiring rapid assembly and disassembly of the reading holder, first, align one of the alignment holes on the external reading holder connector with the fixed shaft head 15 of the support base 1. Then, the user aligns the locking hole at the other end of the reading holder with the exposed quick-release latch 2 operating part 25. Pressing the operating part 25 inward causes the quick-release latch 2 to move inward as a whole, compressing the biasing member 3 until its front end is completely retracted into the shaft hole 11. Maintaining the pressing state, push the locking hole of the reading holder to the side that is tightly against the support base 1. Then, release the pressing force. Under the push of the biasing member 3, the quick-release latch 2 quickly pops outward, causing the front end of the operating part 25 to pass sequentially through the shaft hole 11 of the support base 1 and the locking hole of the reading holder. The reading holder is thus "connected" and locked between the fixed shaft head and the quick-release latch 2. At this time, since the avoidance structure 22 and the guide groove 14 are in a circumferentially offset state (as ensured by the initial assembly or a small rotation operation), the complete cylindrical surface of the main body 21 and the inner wall of the receiving hole 12 form a full circumferential radial constraint, and the mechanism is in a stable locked state.
[0069] Reading rack disassembly:
[0070] When disassembly is required, the user presses the quick-release latch inward again to completely disengage the front end of the operating part from the reading holder's locking hole. The reading holder can then be easily removed around the fixed shaft head for quick separation.
[0071] It should be noted that the fixed shaft head can also be designed as a detachable independent pin. The biasing component 3 is not limited to a coil spring, but can also be a disc spring, elastic rubber column, or other components.
[0072] Industrial application
[0073] This patent provides a locking mechanism for quick-release components, which has the following advantages over the prior art:
[0074] This design integrates multiple separate components (such as pins, springs, independent end caps, and screws) from traditional quick-release mechanisms into a streamlined system consisting of a support base, a one-piece quick-release latch, and a biasing component. Through the cooperation of a "guide groove with a width smaller than the bore diameter" on the support base and a "pass-through clearance structure" on the quick-release latch, a mechanical state transition between "installed position" and "locked position" is cleverly achieved solely through axial movement and rotation. This design eliminates reliance on external fasteners, thereby reducing the total number of parts, simplifying assembly processes, helping to reduce material and assembly costs, and improving the long-term reliability of the mechanism under frequent disassembly and assembly. From a user experience perspective, locking this quick-release mechanism can be completed by hand without tools, making operation more convenient and safer. From a product perspective, the simplified structure also brings greater flexibility to the overall design, enhancing the product's practical value and market competitiveness in a more cost-effective manner.
