Description

Technical Field

[0001] This utility model belongs to the technical field of locker accessories, specifically relating to a hinge cup and hinge. Background Technology

[0002] In modern cabinet and furniture design, hinges are a crucial component connecting cabinet doors to the cabinet body, and their structural design directly affects the product's aesthetics and user experience. Traditional hinges typically have the hinge cup directly exposed on the side of the cabinet door, with the mounting holes and connection structure clearly visible. While this design is simple in structure, it has significant shortcomings in practical application.

[0003] First, exposed mounting structures detract from the overall aesthetics of the cabinet door surface. This is especially true in high-end custom furniture, where visible screw holes and metal components lower the perceived quality of the product. Second, existing hinge cup designs lack effective decorative concealment solutions; even when simple covers are used in some products, they often suffer from insecure fixing and are prone to falling off.

[0004] The existing technology needs further improvement to effectively shield the hinge cup mounting structure without affecting the hinge function. Utility Model Content

[0005] The first objective of this invention is to overcome the problem of exposed installation structure of cabinet hinges in the prior art and to provide a hinge cup.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hinge cup includes a hinge cup body and a decorative cover. The hinge cup body includes a recessed receiving portion and a mounting portion extending outward along the upper edge of the receiving portion. One end of the receiving portion forms a hinge arm connection end and is provided with a clearance opening. The mounting portion is disposed away from the clearance opening. The decorative cover is detachably covered on the mounting portion and is provided with a clearance opening corresponding to the receiving portion. A hidden connection structure is provided between the inner side of the decorative cover and the mounting portion.

[0008] This invention's hinge cup, through the cooperation of a detachable decorative cover and a concealed connection structure, completely conceals the screw holes of the hinge cup mounting part, allowing the cabinet door side to present a complete decorative surface. The concealed connection structure ensures quick assembly and disassembly while avoiding the loosening and detachment issues common with traditional decorative covers. The recessed design ensures that the decorative cover will not interfere with the normal movement of the hinge's transmission components. Compared with existing technologies, this invention achieves a unity of decoration and practicality while maintaining the original function of the hinge. Its connection structure is hidden inside the decorative cover, requiring no additional fasteners, and maintenance can be completed by hand.

[0009] Furthermore, the mounting part is U-shaped overall, with the opening of the U-shape opposite to the clearance opening, and mounting holes are provided on the mounting part. In this design, the mounting part encloses the receiving part on three sides, and mounting holes can be provided on both sides and the bottom of its U-shape for connection with the cabinet door, thereby increasing the stability of the connection between the two and increasing the load-bearing capacity of the hinge cup to meet the needs of heavy-duty doors.

[0010] Furthermore, the concealed connection structure includes a sliding groove and a convex rail. The convex rail is located on opposite sides of the mounting portion along the length of the hinge cup body, and the sliding groove is located on the decorative cover and is adapted to the convex rail. This solution simplifies the installation process of the decorative cover through the sliding engagement of the sliding groove and the convex rail, enabling quick installation and removal.

[0011] Furthermore, both the mounting part and the decorative cover are U-shaped. A connecting step is provided at the lower part of the outer edge of the U-shape. The decorative cover has an L-shaped connecting protrusion corresponding to the connecting step, and the height of the connecting protrusion is the same as the height of the mounting part. A groove is formed between the connecting protrusion and the body of the decorative cover, as described above. The connecting steps on opposite sides form raised rails as described above. During assembly, the decorative cover is slidably fitted onto the mounting part from the side furthest from the hinge cup connection end. In this design, the mounting part and the decorative cover are connected on three sides to prevent the decorative cover from accidentally falling off due to external force. Simultaneously, the sliding direction is offset from the hinge opening and closing direction. The design of the connecting step and the L-shaped connecting protrusion ensures a tight fit between the decorative cover and the mounting part, preventing loosening due to warping or misalignment of the decorative cover.

[0012] Furthermore, a connecting portion is provided on the side of the receiving portion near the hinge arm connection end. The connecting portion protrudes inward from the side wall of the receiving portion, so that the receiving portion forms a recess on the outside of the connecting portion. The connecting portion is provided with a hinge hole, and the connecting portion is connected to the hinge arm through the hinge hole. In this design, the inwardly protruding design of the connecting portion facilitates installation and positioning, provides lateral clearance space for the rivets, and avoids the outward protrusion of the rivets affecting the assembly accuracy of the cabinet door and the hinge cup.

[0013] Furthermore, the opposite sides of the clearance opening are provided with radially outward protruding walls. Due to the setting of the clearance recess, a gap is formed between the receiving part and the front end of the cabinet door mounting groove. The protruding walls of this solution seal the gap between the receiving part and the cabinet door mounting groove, preventing foreign objects from entering the hinge cup and causing the mechanism to jam. At the same time, it makes the transition of the cabinet door side smooth and improves the overall aesthetics.

[0014] Furthermore, the lower surface of the mounting part is provided with a fixing structure, which includes several fixing protrusions. In this solution, the fixing protrusions can increase the friction between the mounting part and the cabinet door contact surface, reduce the risk of hinge cup displacement on the door panel, and are especially suitable for cabinet door scenarios with high frequency of opening and closing.

[0015] Furthermore, the cross-section of the fixed protrusion is toothed.

[0016] Furthermore, the fixing protrusions are strip-shaped, and several fixing protrusions are evenly arranged on the lower surface of the mounting part. In this design, the uniform distribution of the fixing protrusions disperses the installation pressure, avoids local stress concentration that could lead to deformation of the cabinet door surface, and facilitates one-time molding through injection molding or stamping processes, thus reducing production costs.

[0017] Another objective of this invention is to provide a hinge comprising a base assembly and a hinge cup as described above. The base assembly includes a base body, a connecting arm, and a transmission mechanism. The connecting arm is slidably mounted on the base, and the transmission mechanism is mounted on the connecting arm. The base assembly is connected to the hinge cup via the transmission mechanism. Compared with the prior art, this invention, by applying the hinge cup described above, possesses all the advantages of the aforementioned solution. Attached Figure Description

[0028] Example 1:

[0029] See Figure 1-4 As shown, this embodiment discloses a hinge cup 1, including a hinge cup body 10 and a decorative cover 2. The hinge cup body 10 includes a recessed receiving portion 11 and a mounting portion 16 extending outward along the upper edge of the receiving portion 11. One end of the receiving portion 11 forms a hinge arm connection end and is provided with a clearance opening 12. The mounting portion 16 is disposed away from the clearance opening 12. The decorative cover 2 is detachably covered on the mounting portion 16 and is provided with a clearance opening 21 corresponding to the receiving portion 11. A hidden connection structure 22 is provided between the inner side of the decorative cover 2 and the mounting portion 16.

[0030] To increase the stability of the connection between the hinge cup and the cabinet door, and to increase the load-bearing capacity of the hinge cup 1 to meet the requirements of heavy-duty doors, the above-mentioned mounting part 16 is U-shaped in general. The opening of the U-shape is opposite to the clearance opening 12. The mounting part 16 is provided with mounting holes so that the mounting part 16 can surround the receiving part 11 on three sides. Mounting holes can be provided on both sides and the bottom of the U-shape for connection with the cabinet door.

[0031] To simplify the installation process of the hinge cup, the above-mentioned concealed connection structure 22 includes a sliding groove 22b and a convex rail 22a. The convex rail 22a is provided on opposite sides of the mounting part 16 along the length direction of the hinge cup body 10, and the sliding groove 22b is provided on the decorative cover 2 and is adapted to the convex rail 22a.

[0032] Both the mounting part 16 and the decorative cover 2 are U-shaped. A connecting step 22c is provided at the lower part of the outer edge of the U-shape. The decorative cover 2 has an "L"-shaped connecting protrusion 22d corresponding to the connecting step 22c, and the height of the connecting protrusion 22d is the same as the height of the mounting part 16. A groove 22b is formed between the connecting protrusion 22d and the body of the decorative cover 2. During assembly, the decorative cover 2 is slid onto the mounting part 16 from the side furthest from the hinge cup connection end. In this design, the mounting part 16 is connected to the decorative cover 2 on three sides to prevent the decorative cover 2 from accidentally falling off due to external force. Simultaneously, the sliding direction is offset from the opening and closing direction of the hinge 3. The design of the connecting step 22c and the L-shaped connecting protrusion 22d ensures a tight fit between the decorative cover 2 and the mounting part 16, preventing loosening due to warping or misalignment of the decorative cover 2.

[0033] The aforementioned accommodating portion 11 has a connecting portion 13 on the side near the hinge arm connection end. The connecting portion 13 protrudes inward from the side wall of the accommodating portion 11, so that the accommodating portion 11 forms a recess 14 on the outside of the connecting portion 13. The connecting portion 13 has a hinge hole, and the connecting portion 13 is connected to the hinge arm through the hinge hole. In this design, the inward protrusion of the connecting portion 13 facilitates installation and positioning, provides lateral clearance space for the rivets, and avoids the outward protrusion of the rivets affecting the assembly accuracy of the cabinet door and the hinge cup 1.

[0034] The aforementioned clearance opening 12 has radially outward protruding outer walls 15 on both sides. Due to the setting of the clearance recess 14, a gap is formed between the receiving part 11 and the front end of the cabinet door mounting groove. The outer walls 15 of this solution close the gap between the receiving part 11 and the cabinet door mounting groove, preventing foreign objects from entering the hinge cup 1 and causing the mechanism to jam. At the same time, it makes the side of the cabinet door transition smoothly and improves the overall aesthetics.

[0035] The lower surface of the mounting part 16 is provided with a fixing structure, which includes several fixing protrusions 17, thereby increasing the friction between the mounting part 16 and the cabinet door contact surface and reducing the risk of displacement of the hinge cup 1 on the door panel. This is especially suitable for cabinet door scenarios with high frequency of opening and closing.

[0036] The cross-section of the aforementioned fixed protrusion 17 is toothed.

[0037] To facilitate processing, the aforementioned fixing protrusions 17 are strip-shaped, and several fixing protrusions 17 are evenly arranged on the lower surface of the mounting part 16. This allows the installation pressure to be distributed when the hinge cup is assembled on the door panel, avoiding local stress concentration that could cause deformation of the cabinet door surface. At the same time, it facilitates injection molding or stamping processes to form the door in one step, reducing production costs.

[0038] The hinge cup 1 of this invention, through the cooperation of the detachable decorative cover 2 and the concealed connection structure 22, completely conceals the screw holes of the hinge cup mounting part 16, allowing the side of the cabinet door to present a complete decorative surface. Furthermore, the concealed connection structure 22 ensures quick assembly and disassembly while avoiding the loosening and detachment of the traditional decorative cover 2. The clearance part 21 design ensures that the decorative cover 2 will not interfere with the normal movement of the hinge 3's transmission components. Compared with the prior art, this invention achieves a unity of decoration and practicality while maintaining the original function of the hinge 3. Its connection structure is hidden inside the decorative cover 2, requiring no additional fasteners, and maintenance can be completed by hand.
