Description

Technical Field

[0001] This utility model relates to the technical field of furniture hardware accessories, specifically an anti-slip hinge cup for hardware hinges. Background Technology

[0002] In modern panel furniture manufacturing, hinges connect the door panel to the cabinet body and enable the opening and closing of the door panel. During the installation process, the hinge cup needs to be pre-installed in the pre-set mounting holes in the door panel. Then, the main hinge component is hinged to the hinge cup, and the other end of the hinge body is fixed to the side panel of the cabinet body, thus completing the installation of the door panel.

[0003] Currently, hinge cup fixing methods on the market mainly rely on screw fixing. Specifically, hinge cups usually have two or more screw holes on their rim. Workers screw screws into these holes, using the interlocking force between the screws and the board to fix the hinge cup. To meet the growing demand for minimalist aesthetics and concealed installation, smaller hinge cups have appeared on the market. While smaller hinge cups have an aesthetic advantage, the reduced overall size means the screw holes are farther from the critical stress points on the edge of the hinge cup, directly leading to a significant decrease in screw tightening force. Especially when frequent opening and closing or bearing heavy loads are required, the hinge cup is prone to loosening, wobbling, and even gradually coming out of the mounting holes after long-term use, seriously affecting the lifespan and safety of the furniture. To solve these drawbacks, manufacturers use a simple expansion principle to fix the hinge cup. However, expansion structures require high precision in the machining of the mounting holes, often making it difficult to achieve the ideal expansion force. Furthermore, this makes the installation process less convenient and requires more advanced installation tools and skills. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a hardware hinge anti-loosening cup with a simple structure, low manufacturing cost, and an anti-loosening device formed by the pocket body that is embedded in the inner wall of the mounting hole, which significantly enhances the locking force, effectively prevents loosening, and ensures stable and reliable installation.

[0005] The purpose of this utility model is achieved in the following way: a hinge cup for hardware hinges, which includes a panel and a pocket part recessed in the middle of the panel. A hinge seat for hinged to the hinge body is provided on one side of the panel and the pocket. Several outwardly protruding anti-detachment devices are integrally formed on the outer cylindrical surface of the pocket for locking into the inner wall of the mounting hole after the hinge cup is installed in the mounting hole on the plate.

[0007] The outer contour of the boss is larger than the contour of the outer cylindrical surface of the pocket.

[0008] The aforementioned anti-slip device is an inverted buckle formed by stamping the body material outwards.

[0009] The free end of the buckle is bent toward the panel to form an opening for locking between the free end and the outer cylindrical surface of the pocket.

[0010] The aforementioned buckle is a triangular structure that is higher towards the panel and lower towards the back of the panel.

[0011] The anti-detachment device includes at least one buckle disposed on one side of the hinge seat, and at least one boss disposed on the side away from the hinge seat.

[0012] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0013] 2. The anti-detachment device is formed as a single piece, ensuring the overall strength of the hinge cup, simplifying the production process, reducing production costs, and improving the reliability and durability of the hinge cup.

[0014] 3.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. A hinge cup for a hardware hinge includes a panel 1 and a pocket 2 recessed in the middle of the panel 1. A hinge seat for hinged to the hinge body is provided on one side of the panel 1 and the pocket 2. A plurality of outwardly protruding anti-disengagement devices are integrally formed on the outer cylindrical surface of the pocket 2 for engaging with the inner wall of the mounting holes 31 after the hinge cup is installed in the plate 3.

[0024] like Figure 1-5 As shown. The hinge cup structure includes a panel and a recessed pocket portion located in the middle of the panel. The hinge body is hinged to a hinge seat located on one side of the panel and pocket to achieve the connection between the door and the cabinet.

[0025] When the hinge cup is installed, it is passively pressed into the mounting hole of the plate. Several outwardly protruding anti-detachment devices integrally formed on the outer cylindrical surface of the cup contact the inner wall of the mounting hole. These anti-detachment devices protrude outwards, and during the pressing process, they apply radial pressure to the inner wall of the mounting hole, causing the anti-detachment devices to partially embed or press into the plate. This embedding and pressing action generates strong friction and mechanical locking forces, ensuring the hinge cup is securely held against the inner wall of the mounting hole after installation. This effectively resists external axial pull-out forces and radial movement, preventing accidental loosening of the hinge cup and directly enhancing the bonding force between the hinge cup and the plate. This fundamentally improves the anti-detachment performance of the hinge cup, offering a significant advantage over traditional methods relying solely on screws.

[0026] Secondly, the anti-slip device is formed as a single piece of the cup body, rather than an additional component added later. This not only ensures the overall strength of the hinge cup, but also simplifies the manufacturing process, reduces production costs, and improves the reliability and durability of the hinge cup.

[0027] The anti-slip device is a boss 4 formed by stamping the body material of the pocket 2 outward.

[0028] like Figure 6-7 As shown, the anti-detachment device can be configured as a boss formed by stamping the body material outwards. During the installation of the hinge cup, the boss adds several local protrusions to the originally smooth outer surface of the body. During the pressing process of the hinge cup, the boss presses and embeds itself into the plate, forming a strong locking zone. This concentrates the locking force at a specific point, significantly improving the locking effect and efficiency. Simultaneously, the boss is formed by stamping the body material outwards, making it suitable for large-scale production, cost-effective, and allowing for precise boss shape and size. Furthermore, the rigid structure of the boss enables it to withstand significant pressure and maintain its shape, effectively and continuously generating radial support and friction within the plate, reducing the hinge cup's movement within the hole and ensuring its long-term normal use.

[0029] The outer contour of the boss 4 is larger than the outer cylindrical surface of the pocket 2.

[0030] like Figure 6-7 As shown, the outer contour of the boss is larger than the outer contour of the outer cylindrical surface of the cup. During installation, even if there is a certain installation gap error between the hinge cup and the mounting hole, or if the two are only in transitional fit, the clear outer contour dimension design of the boss ensures that the boss can be effectively and forcibly embedded into the plate, rather than just making surface contact, thereby maximizing the locking force and ensuring the locking effect.

[0031] The aforementioned anti-slip device is an inverted buckle 5 formed by stamping the body material of the pocket 2 outwards.

[0032] like Figure 6 As shown, the anti-detachment device can be configured as an inverted buckle stamped outward from the body material of the cup. During the installation of the hinge cup, the inclined surface of the inverted buckle or its elastic portion allows it to slide smoothly across the wall of the mounting hole. Once the hinge cup is in place, the edge of the inverted buckle unfolds or retracts, locking onto the inner wall of the mounting hole to form a strong lock, significantly improving the locking effect and efficiency. When an external force attempts to pull or drag the hinge cup out, the locking surface of the inverted buckle forms an axial resistance force with the hole wall, thus preventing or hindering the hinge cup from detaching. The inverted buckle has a simple structure and can be designed in various shapes and with different elasticities according to different sheet materials and locking force requirements, making it highly practical.

[0033] The free end of the buckle 5 is bent toward the panel 1 to form an opening for holding between the free end and the outer cylindrical surface of the pocket 2.

[0034] like Figure 6 As shown, the free end of the buckle is bent towards the panel, naturally forming an opening for locking between the bent free end and the outer cylindrical surface of the pocket. During installation, when the hinge cup is pressed into the mounting hole, the inner wall material of the mounting hole enters the opening. Once the hinge cup is fully installed, the edge of the opening effectively locks against the sheet metal, creating a strong lock. When an external force attempts to pull or remove the hinge cup, the bent free end engages even more deeply with the sheet metal, preventing the hinge cup from retracting and enhancing the locking effect of the buckle. The buckle can be manufactured through simple stamping and bending, resulting in a simple structure and low manufacturing cost.

[0035] The inverted buckle 5 is a triangular structure that is higher towards the panel 1 and lower towards the opposite side of the panel 1.

[0036] like Figure 6As shown. The overhanging end faces higher towards the panel, forming a locking right angle or acute angle, while the overhanging end faces lower towards the back of the panel, forming a guide slope. When installing the hinge cup, the lower slope helps guide the overhanging end to slide smoothly into the mounting hole, reducing initial resistance. Once the hinge cup is fully pressed in, under external axial pull-out force, the higher end directly engages with the plate and embeds itself into the plate, thus generating strong resistance. The greater the pull-out force, the easier it is for the plate to embed, resulting in strong self-locking and a clear locking direction.

[0037] The anti-detachment device includes at least one buckle 5 disposed on one side of the hinge seat, and at least one boss 4 disposed on the side away from the hinge seat.

[0038] like Figure 4 As shown, the anti-detachment device can include at least one buckle on one side of the hinge seat and at least one boss on the side away from the hinge seat, combining the advantages of both the buckle and the boss. When installing the hinge cup, first place one side of the hinge seat into the mounting hole, i.e., the side with the buckle, at which point the buckle begins to contact the hole wall. Then, the side away from the hinge seat is rotated and pressed in. The pre-pressed buckle provides initial positioning and prevents lifting during this rotational pressing motion. When the hinge cup is nearly fully fitted into the mounting hole, the downward pressure resistance is noticeable. This resistance mainly originates from the boss. The strong squeezing and embedding action of the boss provides solid radial support and axial locking for the final fixation of the hinge cup, while the buckle provides significant unidirectional pull-out resistance. Together, they enhance the locking force, making the entire hinge cup more comprehensively and securely fixed, especially under complex stress conditions. Furthermore, the specific installation method of "placing one side first, then rotating and pressing down on the other side" allows the combined device to function in stages, facilitating user installation and ensuring the final locking effect.

[0039] Users can design different anti-detachment devices according to the different stress characteristics of different parts of the hinge cup, making the anti-detachment effect more targeted. Even under long-term use or vibration, it can provide more durable and reliable fixation and improve the overall stability of the product.

[0040] In summary, an anti-detachment device is integrally formed on the outer cylindrical surface of the hinge cup. To accommodate this anti-detachment device, the maximum diameter of the traditional hinge cup, such as 35mm, is slightly reduced by 0.5mm or remains unchanged. This design is suitable not only for aesthetically pleasing miniaturized hinge cups but also for standard-sized hinge cups, offering wide applicability and enhancing the performance of the hinge cup itself. Furthermore, the mature stamping process simplifies the hinge cup's structure, eliminating the need for additional parts and facilitating mass production.

[0041] The anti-detachment device can be configured with only a boss structure, only an undercut structure, or a combination of both. Different types of anti-detachment devices can be installed at different positions on the hinge cup. These devices press or embed themselves into the inner wall of the mounting hole, generating strong friction and interlocking forces, significantly improving the locking force of the hinge cup. This ensures the hinge cup remains stable even under vibrations during furniture transportation and tensile stress from frequent door opening and closing, effectively preventing it from loosening and improving the overall quality and durability of the furniture. Compared to traditional screw-based locking, the anti-detachment device makes the connection of the hinge cup within the mounting hole more stable and reliable, less prone to shaking or displacement, extending the hinge cup's lifespan, and therefore can be widely adopted.

[0042] 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.
