Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically a quick-release hardware hinge. Background Technology

[0002] Hinges, as a crucial connecting hardware component, are widely used in furniture such as cabinets, wardrobes, and bookcases to connect the cabinet body and doors, enabling the smooth opening and closing of the doors. Traditional hinges typically consist of two main parts: the hinge body (usually including the hinge cup and hinge arm) fixed to the cabinet door, and the base fixed to the side panel of the cabinet body. When installing the cabinet door, the hinge body and the base need to be connected and secured.

[0003] However, through in-depth research and practice on existing technologies, the inventors of this utility model have discovered that currently used hinges have at least the following significant drawbacks in terms of structure and usage: 1. The disassembly and assembly process is cumbersome and inefficient. In current technology, the hinge body and base are generally connected by screws. When disassembly is required for cabinet door installation, repair, adjustment, or cleaning, operators must use screwdrivers or other tools to loosen and remove each screw. Similarly, reinstallation requires laborious alignment of the holes and tightening of each screw. This entire process is not only cumbersome and time-consuming, but also particularly inconvenient in confined spaces (such as cabinet corners) or poorly lit environments, significantly reducing the efficiency of furniture installation and maintenance.

[0004] 2. Repeated disassembly and reassembly can damage furniture panels, leading to decreased connection reliability. This is a more serious problem in existing technology. Currently, modern furniture cabinets and doors largely use engineered wood panels such as particleboard and medium-density fiberboard (MDF). The physical properties of these panels limit their nail-holding power. When screws are first installed, they can be threaded into the panel, ensuring good connection strength. However, once the screws are removed from the panel, the original screw hole passage is easily deformed, enlarged, or the threads are damaged due to stress. When the cabinet door needs to be reinstalled and the screws are screwed into the same screw hole, the tightening force will be far less than the initial installation, and the screws are prone to loosening, slipping, or even failing to tighten. This decrease in connection strength caused by repeated disassembly and reassembly directly leads to various problems: at best, it causes unstable cabinet door installation, resulting in widening gaps, sagging, and misalignment with other door panels over time, affecting the overall aesthetics and normal use of the furniture; at worst, it may cause the cabinet door to fall off unexpectedly due to complete connection failure, posing a serious safety hazard. Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a quick-release hardware hinge that is simple in structure, low in manufacturing cost, and can achieve convenient, quick and repeatable disassembly and assembly between the hinge body and the base, while avoiding damage to furniture boards due to repeated disassembly and assembly operations and ensuring a durable and stable connection reliability.

[0006] The purpose of this utility model is achieved in the following way: a quick-release hardware hinge, which includes a hinge body fixed on the cabinet door and a base fixed on the cabinet body, wherein the hinge body and the base are connected by a quick-release mechanism. The quick-release mechanism includes an opening slot at the front end of the base and an elastic buckle that is elastically installed at the rear end of the base. Correspondingly: a positioning shaft is provided at the bottom front end of the hinge body, and a positioning platform is provided at the rear end of the hinge body. When the hinge body is connected to the base, the positioning shaft is snapped into the opening groove, and the elastic buckle is placed on the positioning platform.

[0007] Furthermore: the opening groove is a U-shaped groove that opens forward and penetrates the front end face of the base.

[0008] Furthermore: baffles are provided on both sides of the base, which are bent upwards, and a limiting area is formed between the baffles on both sides and the base. An adjustment plate is installed at the bottom of the hinge body, and the adjustment plate is installed in the limiting area.

[0009] Furthermore, the base is also provided with guide posts, and correspondingly, the hinge body is provided with guide grooves. When the hinge body is connected to the base, the guide posts are snapped into the guide grooves.

[0010] Furthermore, the elastic buckle is mounted on the base via a hinge shaft, and a reset torsion spring is installed on the hinge shaft. The reset torsion spring drives the elastic buckle to deflect towards the positioning platform at all times.

[0011] Furthermore, a wrench is provided on the top of the elastic buckle extending rearward.

[0012] Furthermore, the elastic buckle is provided with limit posts extending outward at both ends.

[0013] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0014] It is extremely convenient and quick to assemble and disassemble, greatly improving installation and maintenance efficiency.

[0015] 2. No screwdrivers or other tools are required for operation. When installing the cabinet door, simply align the positioning shaft at the front end of the hinge body with the opening slot at the front end of the base, then gently press the rear end of the hinge body towards the base. The positioning platform on the hinge body will press the spring clip, causing it to deflect briefly. The spring clip will then quickly return to its original position under its own elasticity, clicking into place on the positioning platform, thus completing the locking process. The entire process can be completed by hand.

[0016] 3. Disassembly also requires no tools. The operator only needs to use their fingers to turn the lever on the elastic clip to disengage the elastic clip from the positioning table and disengage the positioning shaft from the opening slot. The entire disassembly and assembly process is simple, clear, and quick, completely eliminating the need for tools and solving the problem of tightening screws in confined spaces. The efficiency is dozens of times higher than existing technologies.

[0017] 4. The separation of the hinge body from the base is a purely mechanical separation, completely unrelated to any screws fixing it to the cabinet door or cabinet body. This completely avoids the irreversible damage to the screw holes of particleboard, MDF, and other engineered wood products caused by repeated screw removal, as is common in existing technologies.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. A quick-release hardware hinge includes a hinge body 1 fixed on a cabinet door and a base 2 fixed on the cabinet body. The hinge body 1 and the base 2 are connected by a quick-release mechanism. The quick-release mechanism includes an opening slot 3 at the front end of the base 2 and an elastic buckle 4 that is elastically installed at the rear end of the base 2. Correspondingly: a positioning shaft 5 is provided at the bottom front end of the hinge body 1, and a positioning platform 6 is provided at the rear end of the hinge body 1. When the hinge body 1 is connected to the base 2, the positioning shaft 5 is snapped into the opening groove 3, and the elastic buckle 4 is snapped onto the positioning platform 6.

[0023] In this embodiment: the positioning shaft 5 on the hinge body 1 serves as an "anchor point" and is first inserted into the opening slot 3 on the base 2. This action serves as initial positioning and acts as a "rotating shaft" during installation. After the front end is anchored, the rear end of the hinge body 1 is pressed downwards. At this time, the positioning platform 6 on the hinge body 1 will contact and push open the elastic buckle 4 on the base 2; when the positioning platform 6 passes the locking point of the elastic buckle 4, the elastic buckle 4 will automatically spring back due to its elasticity and "lock" the positioning platform 6 in the opposite direction.

[0024] During disassembly, simply push the elastic buckle 4 open again manually to unlock it from the positioning platform 6. The rear end of the hinge body 1 can then be lifted, and the positioning shaft 5 can be dislodged from the opening slot 3 to complete the separation.

[0025] Compared to traditional technologies, it replaces screw fastening with a "mechanical quick-release mechanism." This allows the entire installation and disassembly process, especially installation, to be completed with just "insert and press," eliminating the need for any screwdrivers or other tools and greatly improving efficiency.

[0026] Meanwhile, since the disassembly and assembly only occur between the hinge body 1 and the base 2, and the base 2 and its screws fixed to the cabinet panel do not need to be touched during cabinet door disassembly and assembly, this completely avoids damage and stripping of the screw holes in the cabinet panel, especially particleboard, caused by repeated screw tightening, ensuring the long-term reliability of the connection.

[0027] In one embodiment: the opening groove 3 is a U-shaped groove that opens forward and penetrates the front end face of the base 2.

[0028] In this embodiment, during installation, the positioning shaft 5 on the hinge body 1 can slide horizontally into the U-shaped groove from the front of the base 2, without the need for complex vertical alignment from above. This simplifies the "aiming" steps of installation. The "opening forward" design is very intuitive; the operator only needs to roughly slide the cabinet door into position so that the positioning shaft 5 can "hook" into the U-shaped groove to complete the first step of anchoring. This provides strong operational guidance and a high tolerance for error.

[0029] In one embodiment: baffles 7 are bent upward on both sides of the base 2, and a limiting area 8 is formed between the baffles 7 on both sides and the base 2. An adjustment plate 9 is installed at the bottom of the hinge body 1, and the adjustment plate 9 is installed in the limiting area 8.

[0030] In this embodiment, the two baffles 7 on the base 2 form a physical boundary, and the adjustment plate 9 below the hinge body 1 is precisely accommodated within this limiting area 8 in width. This prevents the hinge body 1 from wobbling or misaligning on the base 2, ensuring the accurate left and right position of the cabinet door after installation.

[0031] In one embodiment: the base 2 is also provided with a guide post 10, and correspondingly, the hinge body 1 is provided with a guide groove 11. When the hinge body 1 and the base 2 are connected, the guide post 10 is snapped into the guide groove 11.

[0032] In this embodiment: during the downward pressing of the rear end of the hinge body 1, the guide post 10 on the base 2 will be inserted into the guide groove 11 of the hinge body 1 before locking. This ensures that the hinge body 1 will not shift back and forth or left and right during the pressing process, so that the elastic buckle 4 and the positioning platform 6 at the rear end can be accurately aligned and engaged, making the buckling action smoother and more reliable.

[0033] In one embodiment, the elastic buckle 4 is mounted on the base 2 via a hinge shaft 12. A return torsion spring 13 is mounted on the hinge shaft 12, and the return torsion spring 13 drives the elastic buckle 4 to always deflect towards the positioning platform 6. Compared to structures that rely on the elasticity of the material itself, the mechanical structure using the torsion spring 13 is less prone to elastic fatigue, has a longer lifespan, and ensures that it can still provide a stable and strong locking force after thousands of disassembly and assembly cycles. At the same time, the torsion spring 13 can provide a locking force much greater than that of a typical elastic metal sheet, ensuring that the hinge body 1 is firmly fixed to the base 2 and preventing loosening caused by accidental vibration or impact.

[0034] In one embodiment, a wrench 14 is provided on the top of the elastic buckle 4 extending rearward.

[0035] This wrench 14 provides the point of leverage for disassembly. The operator can force the spring clip 4 to rotate against the torsion spring 13 simply by pressing or turning this wrench 14 with their fingers, thereby releasing the clamp on the positioning table 6. This makes disassembly both tool-free and quick and easy.

[0036] In one embodiment, the elastic buckle 4 has limiting posts 15 extending outward at both ends. When the elastic buckle 4 is reset by the torsion spring 13, or when it is rotated by the wrench 14, the two limiting posts 15 will collide with the base 2 or other fixed parts, thereby limiting the maximum angle of its rotation.

[0037] In summary: During installation, align the cabinet door with the hinge body 1 fixed to it with the base 2 fixed to the cabinet. The operator aligns the positioning shaft 5 at the front end of the hinge body 1 and "hooks" it into the U-shaped opening groove 3 at the front end of the base 2. During this process, the adjusting plate 9 at the bottom of the hinge body 1 will enter the limiting area 8 formed by the baffles 7 on both sides of the base 2, achieving initial left-right alignment.

[0038] The operator uses the meshing point of "positioning shaft 5 and opening groove 3" as the pivot point to press the rear end of the hinge body 1 downward.

[0039] During the pressing process: the guide post 10 on the base 2 inserts into the guide groove 11 on the hinge body 1, ensuring accurate pressing trajectory. The positioning platform 6 at the rear end of the hinge body 1 contacts the elastic buckle 4 on the base 2. The positioning platform 6 forces the elastic buckle 4 to rotate around its hinge axis 12, overcoming the elastic force of the return torsion spring 13.

[0040] Once the positioning platform 6 has completely passed the locking point of the elastic buckle 4, the return torsion spring 13 drives the elastic buckle 4 to rebound instantly, and the locking claw of the elastic buckle 4 is firmly "locked" onto the positioning platform 6. At this time, the front end of the hinge body 1 is anchored by 5 and 3, and the rear end is locked by 4 and 6. The installation is complete, and the entire process requires no tools and is stable and reliable.

[0041] Disassembly process Step 1: Release the latch The operator presses or pulls the lever 14 set on the elastic buckle 4 with their fingers.

[0042] Step Two: Overcoming Elasticity The wrench 14 drives the elastic buckle 4 to rotate around the hinge shaft 12, overcoming the elastic force of the reset torsion spring 13, so that the claw of the elastic buckle 4 disengages from the positioning table 6 on the hinge body 1.

[0043] Step 3: Separation At this point, the rear end of the hinge body 1 is unlocked and can be easily lifted.

[0044] Step 4: Remove Move the hinge body 1 backward or upward to disengage the positioning shaft 5 at the front end from the U-shaped opening groove 3.

[0045] Completed: The cabinet door is completely separated from the cabinet body, achieving non-destructive and quick disassembly.

[0046] In this invention, the separation of the hinge body 1 from the base 2 is a purely mechanical separation, without involving any screws fixed to the cabinet door or cabinet body panel. Once the base 2 is fixed to the cabinet body with screws, these screws will not need to be touched during any subsequent cabinet door disassembly, assembly, or maintenance.

[0047] This completely avoids the irreversible damage to screw holes in particleboard, MDF, and other engineered wood products caused by repeated screw removal and installation, as is common in existing technologies. This damage can result in enlarged hole diameters and stripped threads. The quick-release mechanism of this invention is typically made of metal or high-strength engineering plastics and can withstand hundreds or thousands of clicks and releases without damage, ensuring that the connection between the cabinet door and the cabinet body is as secure and reliable as if it were the first time after each reinstallation. Therefore, this design guarantees long-term reliability of the connection, eliminates the safety hazards of loosening, sagging, or even detachment of the cabinet door due to damaged screw holes, and greatly extends the lifespan of the entire furniture product.
