Description

Technical Field

[0001] This invention relates to the field of mechanical fastening devices, and more particularly to an adjustable door hook. Background Technology

[0002] Door hooks, a common household item, are widely used for hanging clothes, backpacks, and other items. They are typically fixed to the edge of the door panel by snapping or hanging. To accommodate door panels of varying thicknesses, various adjustable-gap hook designs have emerged on the market. Some solutions employ threaded adjustment mechanisms, changing the distance between the hook and the support component by rotating a screw. However, threaded structures are prone to loosening under prolonged use or vibration, leading to insecure hook fixation and a risk of falling. Furthermore, each adjustment requires manual tightening, making the process cumbersome and hindering quick installation or removal. Other solutions utilize the deformation of elastic materials to adapt to door thickness. While this simplifies operation, the elastic component may rub against the door panel surface during repeated deformation, potentially scratching the paint. These structures often lack effective limiting mechanisms, making it difficult to maintain the desired gap after adjustment, affecting reliability. Moreover, whether threaded or elastic, most existing adjustable hooks are difficult to operate with one hand or install quickly in one step. Users often need both hands to install or remove the hooks, potentially damaging the door panel due to improper operation. Therefore, how to provide a door hook that is easy to adjust, reliably fixed, and not easily damages the door panel has become a technical problem that needs to be solved in this field. Summary of the Invention

[0003] In view of this, the purpose of this invention is to propose an adjustable door hook that achieves stepless locking and rapid adjustment of the gap through a snap-fit ​​adjustment structure, thereby solving the problems of cumbersome adjustment operation, easy loosening, and easy damage to the door panel of existing hooks.

[0004] To achieve the aforementioned technical objectives, the technical solution adopted by this invention is as follows: an adjustable door hook, comprising a hook body and an adjustment assembly. The hook body includes a hook portion and a mounting portion. The hook portion is configured with a U-shaped and / or L-shaped structure. The mounting portion and the hook portion are integrally formed and disposed opposite to each other, with a locking gap between the mounting portion and the hook portion. The adjustment assembly includes a first adjustment group and a second adjustment group. The first adjustment group is embedded in the mounting portion, and the second adjustment group is movable relative to the first adjustment group. The second adjustment group is placed within the locking gap to adjust the width of the locking gap.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 10 This embodiment provides an adjustable door hook, including a hook body 1 and an adjustment assembly 2. The hook body 1 includes a hook portion 11 and a mounting portion 12. The hook portion 11 is configured with a U-shaped and / or L-shaped structure. The mounting portion 12 is integrally formed with the hook portion 11 and is disposed opposite to it. A locking gap is provided between the mounting portion 12 and the hook portion 11. The adjustment assembly 2 includes a first adjustment group 21 and a second adjustment group 22. The first adjustment group 21 is embedded in the mounting portion 12, and the second adjustment group 22 is adjustable relative to the first adjustment group 21. 21 moves, and the second adjustment group 22 is placed in the engagement gap to adjust the width of the engagement gap; the mounting part 12 is provided with a through limiting slot 121, and the first adjustment group 21 is arranged around the limiting slot 121; the second adjustment group 22 includes a limiting block 221, which can be placed on the other side of the mounting part 12 through the limiting slot 121 so that the second adjustment group 22 is installed on the mounting part 12; the first adjustment group 21 cooperates with the limiting block 221 so that the second adjustment group 22 is disengaged from the mounting part 12.

[0020] In this embodiment, the hook body 1 constitutes the basic frame and load-bearing structure of the device. The hook portion 11 is used for hanging items and is configured in a U-shape and / or L-shape, providing structural adaptability for hanging items of different sizes or types. The mounting portion 12 is used to fix the entire hook to the door panel and is integrally formed with the hook portion 11, ensuring the overall strength and stability of the structure. The mounting portion 12 and the hook portion 11 are arranged opposite to each other, and the space formed between them is the engagement gap. The width of this engagement gap directly determines the door panel thickness that the hook can accommodate.

[0021] The first adjustment group 21 of the adjustment assembly 2 is embedded in the mounting part 12. As an interactive component that can be operated by the user, it cooperates with the second adjustment group 22 to realize the locking and unlocking function. The second adjustment group 22 is the execution component for adjusting the gap. The second adjustment group 22 is placed within the engagement gap and can move relative to the first adjustment group 21, thereby directly changing the position of the second adjustment group 22 in the engagement gap, and thus realizing the adjustment of the engagement gap width. Preferably, the movement of the second adjustment group 22 relative to the first adjustment group 21 can be a linear movement in a direction perpendicular to the door panel plane.

[0022] The through-hole limiting slot 121 provided on the mounting part 12 provides a channel and constraint for the installation and limiting of the second adjustment group 22, thereby "hanging" the second adjustment group 22 as a whole on the mounting part 12, while allowing the second adjustment group 22 to move within a certain range in a direction perpendicular to the mounting part 12. The first adjustment group 21 is located around the limiting slot 121, that is, the position of the first adjustment group 21 covers or surrounds the limiting slot 121 so as to interact with the parts passing through the limiting slot 121; the limiting block 221 included in the second adjustment group 22 is a protrusion or snap-fit ​​structure with a specific size and shape. During installation, the limiting block 221 can pass through the limiting slot 121 and be placed on the other side of the mounting part 12 (i.e., the side facing away from the engagement gap), thereby mechanically locking the entire second adjustment group 22 on the mounting part 12 and preventing it from accidentally falling off from the engagement gap. By operating the first adjustment group 21, the limiting block 221 can be acted upon to release the locking state between it and the mounting part 12. Specifically, through the specific cooperation between the first adjustment group 21 and the limiting block 221, the limiting block 221 can be forced to move or deform, thereby releasing the locking of the limiting block 221 to the mounting part 12 and realizing the disengagement of the second adjustment group 22 from the mounting part 12.

[0023] The adjustable door hook provided in this embodiment is mainly based on a passive adaptation and active unlocking mechanism of the engagement gap. In its natural state, the second adjustment group 22 is in a preset position within the engagement gap. When the user hooks the hook onto the upper edge of the door panel, the door panel enters the engagement gap and contacts the second adjustment group 22. If the door panel thickness does not match the current engagement gap, the door panel applies a force to the second adjustment group 22, pushing it to move relative to the first adjustment group 21, thereby passively adjusting the width of the engagement gap until the gap is tightly fitted to the door panel thickness, achieving adaptive clamping. At this time, the limiting block 221 forms a locking position on the other side of the mounting part 12 to prevent the second adjustment group 22 from loosening and ensure that the hook is securely installed.

[0024] It should be noted that the above-described passively adaptive installation method is only a preferred embodiment. Based on the same mechanical structure, another active pop-out installation method can also be implemented. In the active pop-out installation method, the initial state of the hook can be set as follows: the limiting block 221 has passed through the limiting slot 121 and is in a locked state. At this time, the second adjustment group 22 is located near the mounting part 12 under the constraint of the limiting block 221, making the initial width of the locking gap greater than the thickness of a typical door panel. In use, the hook can be easily suspended on the upper edge of the door panel and moved to the desired position. After determining the position, press the first adjustment group 21 to temporarily disengage the limiting block 221 from the limiting slot 121, causing the second adjustment group 22 to move away from the mounting part 12, i.e., towards the door panel, until the second adjustment group 22 tightly abuts against the door panel surface, reducing the locking gap to match the door panel thickness, achieving a stable clamping. This method also achieves quick, one-step installation and allows the user to freely adjust the hook position before fixing.

[0025] When the hook needs to be removed, press the mounting part 12 towards the door panel so that the limiting block 221 passes through and protrudes from the limiting groove 121. At this time, the engagement gap increases significantly beyond the thickness of the door panel, and there is no longer a tight frictional clamping force between the door panel and the hook. The user can easily remove the hook from the door panel in the vertical direction without any effort. The whole process does not require brute force to pull, effectively avoiding scratches on the paint surface of the door panel.

[0026] This embodiment abandons the traditional threaded adjustment method. Through the cooperation of the snap-fit ​​structure and movable components, it achieves seamless adaptive adjustment of the door panel thickness. No manual tightening or pre-adjustment steps are required during installation, truly achieving "hang and use immediately," greatly simplifying operation. By eliminating the threaded connection, the risk of thread loosening due to vibration or long-term use is fundamentally eliminated, significantly improving the hook's clamping stability and reliability. Furthermore, the active unlocking mechanism makes disassembly easy, effortless, and damage-free. A simple operation widens the snap-fit ​​gap, allowing the hook to be removed, effectively solving the pain points of existing hooks being difficult to disassemble and easily damaging the door panel surface, thus improving the overall user experience and safety of the product.

[0027] In some embodiments, the mounting part 12 is provided with a first connecting column 122 and a second connecting column 123, and the first connecting column 122 and the second connecting column 123 are arranged opposite to each other on both sides of the limiting slot 121; the second adjustment group 22 further includes an adjustment block 222, a third connecting column 223, a fourth connecting column 224, a first elastic element 225 and a second elastic element 226, the adjustment block 222 is provided with a limiting block 221; the third connecting column 223 is disposed on the adjustment block 222; the fourth connecting column 224 is disposed on the adjustment block 222, and is arranged opposite to the third connecting column 223 on both sides of the limiting block 221; the third connecting column 223 is coaxial with the first connecting column 122, and the fourth connecting column 224 is coaxial with the second connecting column 123; the first elastic element 225 is sleeved on the first connecting column 122 and the third connecting column 223; the second elastic element 226 is sleeved on the second connecting column 123 and the fourth connecting column 224.

[0028] In this embodiment, the first connecting column 122 and the second connecting column 123 provided on the mounting part 12 are structural columns used to provide mechanical connection and guidance. The first connecting column 122 and the second connecting column 123 are arranged opposite each other on both sides of the limiting groove 121, and the symmetrical layout provides a stable support foundation for the installation and movement of subsequent components.

[0029] The second adjustment group 22 includes an adjustment block 222, which is a main component that bears and transmits force, with a limiting block 221 disposed on it. The third connecting column 223 and the fourth connecting column 224 disposed on the adjustment block 222 correspond to the first connecting column 122 and the second connecting column 123 on the mounting part 12. The third connecting column 223 and the fourth connecting column 224 are disposed opposite to each other on both sides of the limiting block 221, making the force on the adjustment block 222 more balanced. The third connecting column 223 is coaxial with the first connecting column 122, and the fourth connecting column 224 is coaxial with the second connecting column 123, ensuring that the adjustment block 222 can move smoothly and linearly along the axis defined by these connecting columns.

[0030] The first elastic element 225, sleeved on the first connecting post 122 and the third connecting post 223, and the second elastic element 226, sleeved on the second connecting post 123 and the fourth connecting post 224, together constitute the elastic reset and adaptive force application mechanism of the second adjustment group 22. Through the elastic action of the first elastic element 225 and the second elastic element 226, the adjustment block 222 is given a force tending towards a specific direction. When the hook is engaged with the door panel, if the door panel thickness is greater than the current engagement gap, the door panel will squeeze the adjustment block 222, forcing the adjustment block 222 to overcome the elastic force of the elastic element and move towards the mounting part 12, thereby compressing the first elastic element 225 and the second elastic element 226 and increasing the engagement gap to accommodate the door thickness; conversely, if the door panel is thinner, the restoring force of the elastic element will push the adjustment block 222 to move away from the mounting part 12, reducing the engagement gap to clamp the door panel, thus achieving passive, seamless adaptive adjustment of the door panel thickness without manual intervention.

[0031] Alternatively, before use, the limiting block 221 has already passed through the limiting slot 121 and is in a locked state. At this time, the initial width of the locking gap is greater than the thickness of a typical door panel. The hook can be easily suspended on the upper edge of the door panel and moved to the desired position. After determining the position, press the first adjustment group 21, and the limiting block 221 can be temporarily disengaged from the limiting slot 121. The first elastic element 225 and the second elastic element 226 are released, and their elastic restoring force pushes the adjustment block 222 to move away from the mounting part 12, that is, towards the door panel, until the adjustment block 222 is tightly pressed against the surface of the door panel, and the locking gap is reduced to match the thickness of the door panel, achieving a stable clamping.

[0032] In the disassembly scenario, when the first adjustment group 21 is operated to release the locking block 221 and retract it, the state of the elastic element will change accordingly. Preferably, by operating the first adjustment group 21 and slightly lifting the hook, or by relying on the reaction force of the door panel to press the mounting part 12 towards the door panel, the locking block 221 can be moved further outward of the mounting part 12. At this time, the elastic element is compressed to its limit, and the locking gap is actively expanded to exceed the thickness of the door panel, thereby allowing the hook to be easily removed. The adjustment and disassembly processes described in this embodiment are all completed through locking and elastic cooperation, avoiding the cumbersome and loosening risks of threaded adjustment.

[0033] In some embodiments, the mounting portion 12 includes a first side and a second side, the second side being perpendicular to the first side. The limiting slot 121, the first connecting post 122, and the second connecting post 123 are all disposed on the first side. The side of the second side facing the engagement gap is provided with a sliding slot 124. The adjusting block 222 is provided with an extension 227, which is placed inside the sliding slot 124. The adjusting block 222 can move relative to the sliding slot 124.

[0034] In this embodiment, the first side is the area on the mounting part 12 used to set components such as the limiting groove 121, the first connecting post 122, and the second connecting post 123, and its plane is approximately parallel to the door panel surface. The second side is perpendicular to the first side, and its side facing the engagement gap constitutes a side that contacts or is adjacent to the edge of the door panel.

[0035] The sliding groove 124 on the second side facing the engagement gap is a track or groove structure for accommodating and guiding the movement of the adjusting block 222. The extension 227 on the adjusting block 222 is a portion connected to the main body of the adjusting block 222 and protruding outwards. The extension 227 is placed within the sliding groove 124, such that the adjusting block 222 is constrained on the second side of the mounting portion 12 through the engagement of the extension 227 with the sliding groove 124, and can move relative to the mounting portion 12 along the path defined by the sliding groove 124.

[0036] The extension 227, in cooperation with the sliding groove 124, provides precise guidance and limitation for the movement of the adjustment block 222 in the direction perpendicular to the first side plane. This ensures that the movement trajectory of the adjustment block 222 is stable and does not wobble when it is squeezed by the door panel or driven by the first elastic element 225 and the second elastic element 226. This makes the adjustment process of the locking gap more stable and reliable, and ensures that the contact surface between the adjustment block 222 and the door panel can maintain a uniform pressure distribution, thereby improving the stability of the clamping.

[0037] In some embodiments, the radial cross-section of the sliding groove 124 is L-shaped or T-shaped; the extension 227 is adapted to the sliding groove 124; or, the side wall of the sliding groove 124 is also provided with a side shift groove 126 that extends horizontally; the door hook also includes a pin 3, which is disposed through the extension 227 and is adapted to the side shift groove 126.

[0038] In this embodiment, the cross-sectional shape of the sliding slot 124 is defined perpendicular to its extension direction, and the extension 227 is configured to fit into the sliding slot 124, that is, the shape and size of the extension 227 are such that it can fit into and slide along the interior of the L-shaped or T-shaped sliding slot 124.

[0039] The L-shaped or T-shaped cross-sectional shape provides multi-directional constraints for the extension 227. Preferably, when the sliding groove 124 is L-shaped, its cross-section forms a right-angle bend, which can limit the displacement of the extension 227 in two dimensions: perpendicular to the second side plane and parallel to the second side plane and perpendicular to the extension direction of the sliding groove 124. When the sliding groove 124 is T-shaped, its cross-section forms a more complex constraint, which can more effectively prevent the extension 227 from coming out of the groove, while providing stable sliding guidance.

[0040] In some preferred embodiments, to further enhance the stability and limiting effect of the adjusting block 222 moving within the sliding groove 124 and to prevent it from accidentally dislodging in a direction perpendicular to the door panel plane, the side wall of the sliding groove 124 is also provided with a horizontally penetrating side sliding groove 126. Simultaneously, the door hook also includes a pin 3, which is disposed through the extension 227, and both ends of the pin 3 are adapted to the side sliding groove 126, allowing it to slide along the side sliding groove 126. The side sliding groove 126 is a through hole or groove horizontally penetrating between the vertical walls on both sides of the sliding groove 124; the pin 3 is a rigid shaft arranged horizontally, which passes through the extension 227 of the adjusting block 222 and is fixedly connected or interference-fitted thereto. The diameter of the portions of the pin 3 extending out of the extension 227 is adapted to the width or aperture of the side sliding groove 126, thereby allowing it to be inserted into the side sliding groove 126.

[0041] The extension 227 is positioned within the vertical sliding groove 124, enabling the adjusting block 222 to slide and guide in a direction perpendicular to the door panel (i.e., vertically). The horizontally positioned pin 3, with both ends constrained within the horizontal side-shifting groove 126, effectively locks the extension 227 in the horizontal plane, preventing it from horizontally dislodging from the sliding groove 124, thus ensuring the stability of the connection between the adjusting block 222 and the mounting part 12. Compared to the aforementioned scheme that relies on the end of the extension 227 engaging with an L-shaped or T-shaped cross-section groove, this scheme achieves positioning through an independent pin 3 component, reducing the shape requirements of the extension 227 itself (which can be simplified to a protrusion with a pin hole). This allows for greater flexibility in processing and assembly, and pin connections typically have higher shear strength and durability, resulting in a more intuitive and robust positioning effect. This solution, along with the aforementioned L-shaped or T-shaped cross-section sliding groove solution, can both guide and limit the extension 227. They are parallel optional technical means, and the choice can be made based on production process, cost, and strength requirements.

[0042] This embodiment ensures that the adjusting block 222 will not twist or detach unexpectedly during movement, further enhancing the stability and reliability of the overall movement of the second adjusting group 22, and making the hook structure remain stable during repeated installation, disassembly and adaptive adjustment.

[0043] In some embodiments, the first elastic element 225 and / or the second elastic element 226 are configured as springs.

[0044] In this embodiment, the spring provides linear restoring force, storing and releasing energy through its own compression or stretching deformation. By configuring the first elastic element 225 and the second elastic element 226 as springs, the characteristic that spring force is proportional to deformation within a certain range is utilized. This provides a continuous, stable, and predictable elastic force to the adjusting block 222, resulting in a smooth adjustment process for the locking gap. It can precisely adapt to door panels of different thicknesses and provide continuous clamping force after clamping. Preferably, the spring stiffness coefficient can be selected according to the expected door panel thickness range and the required clamping force to achieve the best adaptive clamping effect and operating feel. Using springs as the first elastic element 225 and the second elastic element 226 results in a mature and reliable structure, controllable cost, and ease of production and assembly, ensuring the long-term performance stability of the entire adjusting assembly 2.

[0045] In some embodiments, the end of the limiting block 221 is further provided with a first deformation flange 228 and a second deformation flange 229, the first deformation flange 228 and the second deformation flange 229 being disposed opposite to each other; the first deformation flange 228 and the second deformation flange 229 can be placed in a naturally extended state and a compressed state; when the first deformation flange 228 and the second deformation flange 229 are placed in the naturally extended state, the width of the end of the limiting block 221 is greater than the width of the limiting groove 121, so that the limiting block 221 is engaged on the mounting part 12; when the first deformation flange 228 and the second deformation flange 229 are placed in the compressed state, the width of the end of the limiting block 221 is less than the width of the limiting groove 121, so that the limiting block 221 can pass through the limiting groove 121 to detach from or penetrate the mounting part 12.

[0046] In this embodiment, the first deformation flange 228 and the second deformation flange 229 are elastic flanges or wing structures disposed on both sides of the end of the limiting block 221. The first deformation flange 228 and the second deformation flange 229 are disposed opposite to each other, so that the end of the limiting block 221 is compressible in the width direction.

[0047] The first deformation flange 228 and the second deformation flange 229 can be placed in a naturally extended state and a compressed state, which is achieved through the elasticity of their own materials or a specific hinge structure. When the first deformation flange 228 and the second deformation flange 229 are in a naturally extended state, the total width of the end of the limiting block 221 is greater than the width of the limiting slot 121, so that the limiting block 221 cannot pass directly through the limiting slot 121, but is engaged on the mounting part 12, locking the second adjustment group 22 in the mounting position; when the first deformation flange 228 and the second deformation flange 229 are subjected to lateral compressive force and placed in a compressed state, the total width of the end of the limiting block 221 is reduced to less than the width of the limiting slot 121, at which time the limiting block 221 obtains the space to pass through the limiting slot 121.

[0048] When passively and adaptively installing the hook on the door, if the door panel thickness does not match the current engagement gap, the force exerted by the door panel on the adjusting block 222 will push the limiting block 21 closer to the limiting slot 121. During this process, the first deformation edge 228 and the second deformation edge 229 are in a compressed state, thereby passively adjusting the width of the engagement gap until the gap is tightly fitted with the door panel thickness, achieving adaptive clamping. The limiting block 221 can also pass through the limiting slot 121. After passing through, the first deformation edge 228 and the second deformation edge 229 return to their natural elongated state, achieving engagement locking.

[0049] If the limiting block 221 has already passed through the limiting slot 121 and is in a locked state before use, the hook can be easily suspended on the upper edge of the door panel and moved to the desired position. After determining the position, press the first adjustment group 21 to compress the first deformation edge 228 and the second deformation edge 229 of the limiting block 221, so that the limiting block 221 can temporarily disengage from the limiting slot 121. At this time, the first elastic element 225 and the second elastic element 226 are released, and their elastic restoring force pushes the adjustment block 222 to move away from the mounting part 12, that is, to move towards the door panel, until the adjustment block 222 tightly abuts against the surface of the door panel, and the locking gap is reduced to match the thickness of the door panel, so as to achieve a stable clamping.

[0050] In some embodiments, the first adjustment group 21 includes an adjustment base 211, a first extension block 212, and a second extension block 213. The adjustment base 211 is engaged with the mounting portion 12. The first extension block 212 is disposed on one side of the adjustment base 211 and on one side of the limiting slot 121. The first extension block 212 is flexibly connected to the adjustment base 211. The second extension block 213 is disposed on the other side of the adjustment base 211 and is disposed opposite to the first extension block 212. The second extension block 213 is disposed on the other side of the limiting slot 121 and is flexibly connected to the adjustment base 211.

[0051] In this embodiment, the adjustment base 211 is the main body of the first adjustment group 21, used to establish a fixed connection with the mounting part 12. Its engagement with the mounting part 12 provides a stable and detachable mounting base. The first extension block 212 and the second extension block 213 are operating components respectively disposed on both sides of the adjustment base 211. The first extension block 212 is located on one side of the limiting slot 121, and the second extension block 213 is located on the other side of the limiting slot 121. The two are arranged opposite to each other, and can apply force to the limiting block 221 passing through the limiting slot 121 from both sides.

[0052] The first extension block 212 and the second extension block 213 are flexibly connected to the adjusting base 211. Preferably, the first extension block 212 and the second extension block 213 are connected to the adjusting base 211 by an elastic material or structure (such as a thin wall or hinge), allowing the first extension block 212 and the second extension block 213 to undergo a certain degree of elastic deflection or displacement relative to the adjusting base 211. The flexible connection allows the first extension block 212 and the second extension block 213 to move inward (towards the limiting block 221) when pressed, and to elastically return to their original position after the pressing force is removed. Preferably, the outer surfaces of the first extension block 212 and the second extension block 213 may be provided with anti-slip textures or ergonomic curved surfaces to improve the operating feel.

[0053] By pressing the first extension block 212 and the second extension block 213, which are positioned opposite each other, they move towards the center under the action of flexible connection. This allows the first deformation edge 228 and the second deformation edge 229 at the ends of the limiting block 221 to be squeezed from both sides simultaneously, forcing them from their naturally extended state to a compressed state. This allows the second adjustment group 22 to disengage from the mounting part 12. In this embodiment, the unlocking action can be completed by pinching the first extension block 212 and the second extension block 213 with one hand, making the operation intuitive and effortless.

[0054] In some embodiments, the first adjustment group 21 further includes a first sheet 214 and a second sheet 215, wherein the first sheet 214 connects the first extension block 212 and the adjustment base 211; and the second sheet 215 connects the second extension block 213 and the adjustment base 211.

[0055] In this embodiment, the first sheet 214 is a sheet-like structure connecting the first extension block 212 and the adjustment base 211, and the second sheet 215 is a sheet-like structure connecting the second extension block 213 and the adjustment base 211. The first sheet 214 and the second sheet 215 provide the required flexibility through their small thickness and specific material properties.

[0056] The first thin sheet 214 and the second thin sheet 215 serve as a specific implementation of the flexible connection. Their thin sheet structure allows for high bending flexibility at the connection point, while ensuring the strength of the connection between the first extension block 212, the second extension block 213, and the adjusting base 211. Preferably, the first thin sheet 214 and the second thin sheet 215 can be integrally formed from the same material as the first extension block 212, the second extension block 213, and the adjusting base 211. By locally thinning to form a hinge effect, the fulcrum position and reset torque of the first extension block 212 and the second extension block 213 can be precisely controlled while ensuring the overall structural integrity. This results in a clear pressing feel and accurate and reliable reset.

[0057] In some embodiments, the first sheet 214, the first extension block 212, the adjustment base 211, the second extension block 213, and the second sheet 215 are integrally formed.

[0058] In this embodiment, the first sheet 214, the first extension block 212, the adjustment base 211, the second extension block 213, and the second sheet 215 are integrally formed. They can be formed into a complete and indivisible single part by continuous processing from a single material through processes such as injection molding, stamping, or casting.

[0059] The one-piece molding eliminates the assembly interfaces between components, avoiding the risk of structural failure due to loose connections, loose screws, or welding failures, and significantly improving the overall structural strength and long-term reliability of the first adjustment group 21. Preferably, the one-piece molded first adjustment group 21 can be made of engineering plastics (such as POM, nylon) or metal materials with good elasticity and toughness. The thickness and shape of the first sheet 214 and the second sheet 215 are precisely controlled through mold design, thereby ensuring the rigidity of the main body of the adjustment base 211 while giving the first extension block 212 and the second extension block 213 the required reusable elastic deflection capability. This simplifies the production and assembly process, reduces costs, and ensures the consistency of product performance.

[0060] In some embodiments, the end of the mounting portion 12 extends downward with a locking section 125; the end of the adjusting base 211 is provided with a locking groove 216; the locking section 125 is adapted to the locking groove 216 so that the adjusting base 211 is fixed to the mounting portion 12.

[0061] In this embodiment, the engaging section 125 is a protrusion, tongue, or similar structure on the mounting part 12 for positioning and fixing with the first adjustment group 21; the engaging slot 216 is a groove, opening, or snap-fit ​​structure that matches the shape and size of the engaging section 125.

[0062] The engaging section 125 is adapted to the engaging slot 216, that is, the engaging section 125 can be embedded or snapped into the engaging slot 216. Through interference fit, elastic buckle, or shape interlocking, the adjusting base 211 is quickly positioned and firmly fixed on the mounting part 12, preventing the adjusting base 211 from loosening or shifting during use. Preferably, the engagement between the engaging section 125 and the engaging slot 216 can be designed with a guide bevel to facilitate alignment and snapping during assembly. The engaging connection method of this embodiment does not require additional fasteners, simplifying the installation steps of the first adjusting group 21 and facilitating production assembly. It also provides a reliable installation base for the first adjusting group 21, ensuring that the first extension block 212 and the second extension block 213 can be accurately aligned with both sides of the limiting slot 121, thereby reliably performing the squeezing and unlocking function of the limiting block 221.

[0063] By adopting the above technical solution, this invention differs from the prior art and has the following beneficial effects: The structural cooperation between the hook body 1 and the adjustment component 2 simplifies the installation and disassembly process and improves reliability. The second adjustment group 22 can move relative to the first adjustment group 21 within the engagement gap, and combined with the elastic action of the first elastic element 225 and the second elastic element 226, it allows the hook to passively and seamlessly adaptively adjust the engagement gap width when it engages with the door panel, precisely adapting to different door panel thicknesses without manual twisting or pre-adjustment, achieving immediate use upon hanging. Simultaneously, the cooperation between the limiting block 221 in the first adjustment group 21 and the second adjustment group 22, through the compression of the first deformation edge 228 and the second deformation edge 229 at the end of the limiting block 221 by the first extension block 212 and the second extension block 213, provides an active unlocking mechanism. Operating the first adjustment group 21 can deform the limiting block 221 and disengage it from the limiting slot 121, releasing the locking between the second adjustment group 22 and the mounting part 12, thus enabling the limiting block 221 to actively pop out to adapt to the door panel thickness. In addition, a slight press on the mounting part 12 can utilize the door panel's reaction force to push the limiting block 221 out of the limiting slot 121, rapidly increasing the locking gap, allowing the hook to be easily and without damage removed from the door panel, avoiding the problems of difficult disassembly and easy damage to the door panel associated with traditional hooks. The above technical solution abandons the easily loosened threaded adjustment method, and through the combination of locking and elasticity, optimizes the user experience while ensuring clamping stability.
