Description

Technical Field

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

[0002] In modern furniture manufacturing, hinges are an indispensable core component connecting the cabinet body and cabinet doors, enabling opening and closing. Common furniture hinges, especially those with a "quick-release" design, typically include a hinge cup installed in a recess in the cabinet door, a hinge arm connecting the hinge cup, and a base fixed to the side panel of the cabinet body. The hinge arm and hinge cup are hinged together by a complex four-bar linkage mechanism, such as upper and lower connecting rods, to achieve smooth opening and closing of the cabinet door.

[0003] To improve user experience and prevent cabinet doors from colliding violently with the cabinet body due to excessive speed when closing, thus avoiding noise and damage to the furniture, existing hinges generally integrate damping technology. The common practice is to add a damper to the base or hinge arm. When the cabinet door closes to a specific angle, the damper engages, generating damping force to allow the door to close slowly and quietly.

[0004] However, the inventors discovered in practice that although existing hinges are relatively perfect in function, they still have significant shortcomings in terms of ease of installation, especially in terms of adaptability to the installation environment. The installation process is usually as follows: the installer first fixes the main part, consisting of the hinge cup and hinge arm, to the cabinet door, and then, supporting the cabinet door with both hands, aligns the hinge arm with and installs it onto the base that is pre-fixed to the cabinet.

[0005] The structural design of this "quick-installation" docking process dictates that it must follow a fixed installation sequence: the installer must first hook the front end of the hinge arm onto the front end of the base, and then, using the hook point as a fulcrum, press the tail of the hinge arm downwards, using the elastic tail hook at the tail of the hinge arm to lock it in place with the corresponding slot or groove at the rear end of the base with a "click".

[0006] It is precisely this fixed installation logic of "first then last" that leads to the following insurmountable drawbacks:

[0007] 1. Installation Interference and Spatial Limitations: To smoothly hook the front hook of the hinge arm into the base, the installer must lift the tail of the hinge arm at a significant angle. This action causes the entire cabinet door to tilt outwards. If the cabinet door's installation location is very compact, such as its hinge side being adjacent to a wall or another fixed tall cabinet, the outward tilting motion during installation will be hindered by these obstacles, preventing the front hook from aligning and engaging, or even making installation impossible. This rigid requirement for installation space, especially lateral space on the hinge side, greatly limits the application scenarios of this type of hinge.

[0008] 2. The installation process is laborious and inconvenient: Since the door panel needs to be tilted first to hang the front end, the installer not only has to bear the entire weight of the cabinet door, but also has to precisely control the tilt angle of the door panel to complete the alignment. The whole process is laborious and requires a high level of skill from the installer, which also affects the installation efficiency. Therefore, it is necessary to make further improvements. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a hinge quick-installation structure that is more compact and easier to install.

[0010] The purpose of this utility model is achieved through the following means: a hinge quick-installation structure, including a hinge arm, a hinge cup, and a base installed on a cabinet. The hinge arm and the hinge cup are hinged together by an upper connecting rod and a lower connecting rod. The hinge arm is provided with a receiving groove, and an adjusting seat is installed in the receiving groove. The adjusting seat is installed in the receiving groove by an adjusting screw and an eccentric pin. The top of the base is provided with a guide rail that protrudes upward. Correspondingly, the bottom of the adjusting seat is provided with a guide groove, and the guide rail and the guide groove are slidably engaged.

[0011] The tail of the adjusting seat is hinged with a tail hook, and the tail of the guide rail is provided with a rear hanging groove that cooperates with the tail hook.

[0012] The head of the adjustment seat is provided with a limit groove, and the head of the guide rail is provided with a front hanging groove.

[0013] The adjusting seat is also equipped with a locking pin that can slide within the limiting groove. The locking pin is driven by an elastic mechanism to lockably engage with the front mounting groove.

[0014] Furthermore, the elastic mechanism is a torsion spring mounted on the adjusting seat.

[0015] Furthermore: the adjustment seat is provided with a mounting seat, the spring coil of the torsion spring is fitted on the mounting seat, and the support legs of the torsion spring are pressed on the mounting seat and the locking pin respectively.

[0016] Furthermore, the mounting base is formed by stamping and bending the material of the adjusting base body.

[0017] Furthermore, the torsion spring is a double torsion spring with two spring coils. Correspondingly, the adjusting seat has two mounting seats, and the two spring coils of the torsion spring are fitted onto the corresponding two mounting seats.

[0018] Furthermore, the limiting groove is an elongated groove.

[0019] Furthermore, a spring is provided between the adjusting seat and the tail hook, and the spring drives the tail hook to swing backward in the direction of the hanging slot.

[0020] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0021] 2. This utility model, by setting a sliding fit between the guide rail and the guide groove, and setting a tail hook and rear hanging groove hooking mechanism at the tail end, and a locking post and front hanging groove locking mechanism at the head, makes the installation process no longer limited to a single path, and installers can flexibly choose the installation method according to the actual environment.

[0022] 3. When there is ample installation space, installers can choose the traditional operating method: first, hook the tail hook at the end of the adjusting seat into the rear mounting slot of the base, and then use this as a fulcrum to easily press the front end of the adjusting seat downwards, causing the locking pin to automatically slide across the guide rail surface and lock into the front mounting slot with a "click," completing the installation. This process is intuitive and quick.

[0023] 4. When encountering obstacles such as walls or other cabinets adjacent to the hinge side, installers do not need to tilt the door panel. Simply keep the door panel roughly parallel to the cabinet, align the guide groove at the bottom of the adjustment base with the guide rail on the base, and then slide the entire adjustment base horizontally along the guide rail. During the sliding process, the tail hook and locking pin will sequentially or simultaneously align and engage with the rear and front mounting slots, thus completing the installation. This greatly expands the applicability of the hinge products, making them suitable for various compact and extreme installation environments. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings. A hinge quick-release structure includes a hinge arm 1, a hinge cup 2, and a base 8 mounted on a cabinet. The hinge arm 1 and the hinge cup 2 are hinged together by an upper connecting rod 3 and a lower connecting rod 4. The hinge arm 1 is provided with a receiving groove 11, and an adjusting seat 5 is installed in the receiving groove 11. The adjusting seat 5 is installed in the receiving groove 11 by an adjusting screw 6 and an eccentric nail 7.

[0032] The base 8 has a guide rail 81 that protrudes upward from the top, and correspondingly, the adjustment seat 5 has a guide groove 51 at the bottom, with the guide rail 81 and the guide groove 51 slidingly engaged.

[0033] The tail of the adjusting seat 5 is hinged with a tail hook 52, and the tail of the guide rail 81 is provided with a rear hanging groove 82 that cooperates with the tail hook 52.

[0034] The head of the adjusting seat 5 is provided with a limiting groove 53, and the head of the guide rail 81 is provided with a front hanging groove 83.

[0035] The adjusting seat 5 is also equipped with a locking pin 55 that can slide within the limiting groove 53. The locking pin 55 is driven by an elastic mechanism to lockably engage with the front hanging groove 83.

[0036] In this embodiment, the sliding fit between the guide rail 81 and the guide groove 51 is the basis for all installation actions. It provides a precise and stable movement trajectory for the adjusting seat 5 during installation, effectively preventing lateral wobbling and ensuring that the adjusting seat 5 can be smoothly aligned and installed onto the base.

[0037] Compared to traditional technologies, this case presents two installation modes:

[0038] Mode 1, tilt mounting: The installer can first hook the tail hook 52 at the end of the adjusting seat 5 into the rear mounting slot 82 of the base 8 to form a stable fulcrum, and then press down on the front end of the adjusting seat 5. During the pressing process, the locking pin 55 will slide along the surface of the guide rail 81, and when it is aligned with the front mounting slot 83, it will automatically spring in and lock under the action of the elastic mechanism.

[0039] Mode 2, horizontal installation: When the installation space is narrow and the cabinet door cannot be tilted, the installer can adjust the seat 5 in a nearly horizontal position so that the guide groove 51 at the bottom is directly fitted onto the guide rail 81. Then, the entire adjusting seat 5 is slid backward along the guide rail 81 until the tail hook 52 and the locking pin 55 are engaged with the rear hanging groove 82 and the front hanging groove 83 respectively.

[0040] This dual-mode installation capability completely solves the space limitation problem caused by the fixed installation sequence of existing technologies, greatly enhancing the product's adaptability.

[0041] In one embodiment, the elastic mechanism is a torsion spring 9 mounted on the adjusting seat 5.

[0042] When the locking pin 55 is retracted under force during installation or removal, it forces the torsion arm of the torsion spring 9 to twist, thereby storing elastic energy in the spring coil. Once the external force disappears, i.e., when the locking pin 55 aligns with the front mounting slot 83, the energy stored in the torsion spring 9 is released instantaneously, driving the locking pin 55 to spring quickly and forcefully into the slot, achieving reliable locking. The technical advantages are that the torsion spring has a simple structure, occupies little space, has stable performance, and a long service life. It is an elastic element that is very suitable for providing the driving force for this type of reciprocating linear motion, combining cost-effectiveness and reliability.

[0043] In one embodiment, the adjusting seat 5 is provided with a mounting seat 54, the spring ring 91 of the torsion spring 9 is fitted on the mounting seat 54, and the support foot 92 of the torsion spring 9 presses on the mounting seat 54 and the locking post 55 respectively.

[0044] In this embodiment, the mounting base 54 provides a stable rotation axis and radial support for the coil 91 of the torsion spring 9. One of the two supporting feet 92 of the torsion spring 9 abuts against the locking pin 55, serving as the force-applying end to drive the movement of the locking pin 55; the other abuts against the mounting base 54 itself or a nearby structure, serving as the reaction force end, forming a complete mechanical circuit. The technical advantage lies in the precise positioning of this mounting structure, ensuring that the force of the torsion spring can be stably and efficiently transmitted to the locking pin 55, avoiding spring slippage or failure during operation, and guaranteeing the long-term reliability of the locking function.

[0045] In one embodiment, the mounting base 54 is formed by stamping and bending the material of the adjusting base 5. During the stamping process of the adjusting base 5, one or more protruding stakes or plates are directly cut and bent from the metal sheet using a mold design, serving as the mounting base 54. The technical advantages are significant: it achieves integrated components, eliminating the need for additional welding, riveting, or other secondary processing steps to fix an independent mounting base, thereby 1) simplifying the production process; 2) reducing manufacturing costs; and 3) reducing potential failure points such as weld breakage, improving the overall strength and reliability of the structure.

[0046] In one embodiment: the torsion spring 9 is a double torsion spring with two spring coils 91. Correspondingly, the adjusting seat 5 is provided with two mounting seats 54, and the two spring coils 91 of the torsion spring 9 are fitted onto the corresponding two mounting seats 54.

[0047] In this embodiment, the two coils 91 of the double torsion spring are respectively mounted on two mounting bases 54. The two coils of the double torsion spring work together to provide an elastic driving force. This provides a larger or more balanced elastic force, suitable for heavy-duty cabinet doors that require stronger locking force. At the same time, the stress distribution is more uniform. Compared with a single torsion spring, the double torsion spring has less deformation and material stress when generating the same force, which can significantly improve the fatigue resistance and service life of the spring.

[0048] In one embodiment, the limiting groove 53 is an elongated groove. The pin portion of the locking pin 55 passes through this elongated groove. The length of the groove determines the maximum sliding stroke of the locking pin 55, while the width of the groove limits its displacement perpendicular to the sliding direction. The elongated groove provides a precise single-degree-of-freedom linear guide for the locking pin 55, ensuring smooth, stable, and unobstructed reciprocating motion without rotational wobble, thus guaranteeing smooth and accurate locking action.

[0049] In one embodiment: a spring is provided between the adjusting seat 5 and the tail hook 52, and the spring drives the tail hook 52 to swing in the direction of the rear hanging groove 82.

[0050] In this embodiment, a spring, such as a small torsion spring or compression spring, is added between the adjusting seat 5 and the tail hook 52 hinged thereon. This spring continuously applies a force to the tail hook 52, ensuring that it always tends to engage with the rear hanging groove 82. The technical advantage is that it can actively eliminate any possible gaps between the tail hook 52 and the rear hanging groove 82, making the connection at the tail end tighter and more secure. This effectively prevents the cabinet door from loosening or making abnormal noises due to vibration or other reasons during long-term use, further improving the stability and reliability of the overall connection.

[0051] In summary, in this case, a clever quick-release system for locking the head is achieved by constructing a basic sliding guide provided by the guide rail 81 and guide groove 51 between the hinge adjustment seat 5 and the base 8, the tail hook 52 and rear hanging groove 82 providing tail attachment support, and a locking pin 55 driven by a torsion spring 9 that can slide in the elongated waist-shaped limiting groove 53 cooperating with the front hanging groove 83.

[0052] This system eliminates the fixed "first then last" installation sequence for hinges. Users can choose the traditional method of first attaching the tail hook and then pressing the head, or, in space-constrained situations, directly slide the adjusting seat into the base to complete the installation, offering extremely high installation flexibility. The torsion spring 9, acting as an elastic mechanism, provides stable driving force to the locking pin 55 through its reliable mounting base 54. This mounting base can be stamped from the adjusting seat 5 body to optimize cost and structure, or a double torsion spring can be used to enhance performance. Simultaneously, the spring added at the tail hook 52 further ensures a secure and wobbly connection at the tail. Ultimately, this solution works synergistically to achieve a convenient, widely applicable, and reliably stable hinge quick-installation structure, thus allowing for widespread adoption.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
