Description

Technical Field

[0001] This application belongs to the field of hinge technology, and particularly relates to a thin-sheet stacked hinge. Background Technology

[0002] Hinges are widely used in various doors, windows, and storage cabinets. In actual use, after initial installation, gaps often appear between the door and cabinet. To adjust these gaps, the height of the hinge's connecting arm is typically adjusted. However, when the connecting arm is raised, the contact area between it and the hinge body decreases, causing the connecting arm to bear greater concentrated stress. If the connecting arm remains raised and under continuous stress for an extended period, it is prone to fatigue damage or breakage. Furthermore, due to the lack of an effective support structure, the connecting arm often exhibits poor stability after adjustment, easily resulting in shaking or positional shifts, affecting the overall structural performance and reliability.

[0042] Hinges are widely used in various doors, windows, and storage cabinets. In actual use, after initial installation, gaps often appear between the door and cabinet. To adjust these gaps, the height of the hinge's connecting arm is typically adjusted. However, when the connecting arm is raised, the contact area between it and the hinge body decreases, causing the connecting arm to bear greater concentrated stress. If the connecting arm remains raised and under continuous stress for an extended period, it is prone to fatigue damage or breakage. Furthermore, due to the lack of an effective support structure, the connecting arm often exhibits poor stability after adjustment, easily resulting in shaking or positional shifts, affecting the overall structural performance and reliability.

[0043] Based on the above, this application provides a thin-sheet stacked hinge. This makes the connecting arm less prone to damage, breakage, or poor stability even when raised for extended periods. See below for details.

[0044] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0045] Please see Figures 1 to 4 This application provides a sheet-stacked hinge, which includes: a sheet-stacked hinge base 100, a connecting arm 40, and a hinge cup 200. The following is a detailed description:

[0046] The sheet-stacked hinge chassis 100 includes a first chassis 10, a second chassis 20, and a third chassis 30.

[0047] A first chassis 10 has a receiving groove 13 on its first surface. A first perforated hole 11 is formed in the bottom wall of the receiving groove 13. A second perforated hole 12 is also formed on the first chassis 10. A first protrusion 14 and a second protrusion 15 are also formed on the first surface of the first chassis 10, respectively located near the two side edges of the receiving groove 13. The receiving groove 13 defines the installation position of the connecting arm 40 within the chassis. The first perforated hole 11 and the second perforated hole 12 expose the first fixing hole 301 and the second fixing hole 302, respectively, to facilitate the installation of positioning components.

[0048] The second base 20 is attached to the second surface of the first base 10 and fixedly connected to it. The second base 20 has a third perforated hole 23 and a fourth perforated hole 24. The second base 20 serves as an intermediate transition structure, connecting the first base 10 and the third base 30 into a whole, thereby enhancing the rigidity and stability of the base structure. Specifically, there can be multiple third perforated holes 23 and fourth perforated holes 24.

[0049] The third base 30 is attached to the side of the second base 20 away from the first base 10. The third base 30 has a first fixing hole 301 and a second fixing hole 302. The third base 30 serves as a bottom support and plays a role in sealing, reinforcing and pressing the entire base structure. In practical applications, it can be used as a contact surface with the cabinet.

[0050] The connecting arm 40, also known as a hinge arm, is housed within the receiving groove 13 and is fixedly connected to the first base 10 via an adjusting shaft 41. Both ends of the adjusting shaft 41 are connected to the connecting arm 40 and the first base 10, respectively. The adjusting shaft 41 is used to adjust the raised height of the connecting arm 40. The connecting arm 40 has a fifth perforated hole 405. When the adjusting shaft 41 rotates in a predetermined direction, it extends, thereby raising the connecting arm 40 to adjust the gap between the door and the cabinet. In some cases, the adjusting shaft 41 can also rotate in the opposite direction to the predetermined direction, lowering it and thus lowering the connecting arm 40. The gap between the door and the cabinet can also be adjusted according to actual conditions.

[0051] The hinge cup 200 is rotatably connected to one end of the connecting arm away from the sheet-stacked hinge base, for mounting to the door body or door panel. In some embodiments, the hinge cup 200 may be a damping hinge cup, thereby providing a cushioning effect during door closing, reducing the impact force when the door closes, avoiding noise and structural damage, and improving service life and user comfort.

[0052] In this embodiment, the first hollow hole 11, the third hollow hole 23, the fifth hollow hole 405, and the first fixing hole 301 are respectively provided, and the second hollow hole 12, the fourth hollow hole 24, and the second fixing hole 302 are respectively provided.

[0053] In practical use, the first perforated hole 11, the third perforated hole 23, and the fifth perforated hole 405 are continuous to expose the first fixing hole 301 on the third base 30, and the second perforated hole 12 and the fourth perforated hole 24 are continuous to expose the second fixing hole 302 on the third base 10. After exposing the first fixing hole 301 and the second fixing hole 302, the third base 30 can be directly fixed to the cabinet by passing fasteners through the first fixing hole 301 and the second fixing hole 302, so that the entire base can be fixed to the cabinet in a fully assembled state, which is convenient for installation. In addition, the first perforated hole 11, the third perforated hole 23, and the fifth perforated hole 405 all coincide with the connecting arm 40 in the vertical direction, which improves the surface space utilization of the thin-plate stacked hinge base 100, making the volume of the thin-plate stacked hinge base 100 smaller and thinner. The fasteners can be bolts, screws, etc.

[0054] Specifically, there can be one or more first fixing holes 301, and these first fixing holes 301 can be arranged in a parallel and spaced manner. Similarly, there can be one or more second fixing holes 302, also arranged in a parallel and spaced manner. Increasing the number of fixing holes can improve the stability after installation.

[0055] In this embodiment, the first chassis 10 is provided with a first limiting plate 103 and a second limiting plate 104 on both sides of its side edge. The first limiting plate 103 and the second limiting plate 104 are both located on the second surface and are bent toward the side that is close to each other to form a first guide groove and a second guide groove.

[0056] The second chassis 20 has a first guide plate 201 and a second guide plate 202 respectively on its two side edges. The first guide plate 201 is used to be embedded in the first guide groove, and the second guide plate 202 is used to be embedded in the second guide groove.

[0057] The first limiting plate 103 can be bent into an L-shaped snap-fit ​​structure to hook onto the first guide plate 201 of the second chassis 20. The first guide groove and the second guide groove are used to limit, guide and install the second chassis 20. In actual assembly, the second chassis 20 can be directly installed in an insert manner along the direction of the first guide groove and the second guide groove.

[0058] In this embodiment, the third chassis 30 has a third guide plate 303 on the side facing the second chassis 20. The third guide plate 303 is bent inward to form a third guide groove, which is used to fit into the edge of the second chassis 20. After bending, the third guide plate can have an L-shaped snap-fit ​​structure to hook onto the second chassis 20.

[0059] Specifically, the third guide plate 303 is located at the rear end of the third chassis 30, that is, at the end of the third chassis 30 away from the connecting arm 40.

[0060] In this embodiment, a first clearance groove and a second clearance groove are formed on the second surface of the first chassis. The position of the first clearance groove corresponds to the position of the first protrusion, and the position of the second clearance groove corresponds to the position of the second protrusion.

[0061] The third chassis is also provided with a first hook block and a second hook block. The second chassis is provided with a first positioning hole and a second positioning hole. The first hook block is used to pass through and be engaged in the first positioning hole, and the part of the first hook block passing through the first positioning hole is accommodated in the first clearance groove. The second hook block is used to pass through and be engaged in the second positioning hole, and the part of the second hook block passing through the second positioning hole is accommodated in the second clearance groove. This allows the second chassis and the third chassis to be connected relatively stably to avoid separation. The first clearance groove accommodates the part of the first hook block that protrudes from the first positioning hole, so that the second chassis and the third chassis can fit tightly together, avoiding gaps caused by the part of the first hook block protruding from the first positioning hole lifting the second chassis.

[0062] Specifically, the first protrusion and the second protrusion can be formed by stamping the first chassis 10, while the first clearance groove and the second clearance groove are naturally formed on the second surface of the first chassis.

[0063] This application provides a receiving groove 13 on the first surface of the first chassis 10, and provides a first protrusion 14 and a second protrusion 15 on both sides of the receiving groove 13. When the connecting arm 40 is lifted by the adjusting shaft 41, the first protrusion 14 and the second protrusion 15 can provide limiting support for both sides of the connecting arm 40, thereby effectively reducing the suspended force area of ​​the connecting arm 40, reducing its force concentration, and improving the stability of the connecting arm 40 in the lifted state, preventing it from breaking due to prolonged suspended force, and effectively extending the service life of the hinge device. At the same time, the first protrusion and the second protrusion can also reduce the shaking and displacement of the connecting arm 40 during the adjustment process, improving the reliability and accuracy of the overall hinge structure.

[0064] In this embodiment, one end of the receiving groove 13 extends to the edge of the first chassis 10, and the bottom wall of the receiving groove 13 is also provided with a first slot 131. The first slot 131 is connected to the edge of the first chassis 10 and is used to be fixedly connected to the adjusting shaft 41.

[0065] The receiving slot 13 has an open slot structure, which makes it easy for the adjusting shaft 41 or the connecting arm 40 to be directly inserted into the receiving slot 13 from the side of the chassis. This can reduce positional constraints during the assembly process and improve assembly efficiency.

[0066] Similarly, the first slot 131 is also an open structure, which makes it easy for the adjustment shaft 41 to be directly inserted from the side of the chassis. The first slot 131 provides a precise connection point between the adjustment shaft 41 and the first chassis 10, and also restricts the direction of movement of the adjustment shaft 41, so that it is not easy to deviate when subjected to force.

[0067] In an optional embodiment, the hinge cup includes a damping component that generates damping force when the sheet-stacked hinge is closed, thereby effectively buffering the unfolding movement of the connecting arm and preventing the door from opening rapidly due to inertia, causing impact, or structural fatigue. Furthermore, the damping component improves the smoothness and control of the opening process, extends the overall service life of the hinge, and is suitable for scenarios involving high-frequency door opening and closing. In this embodiment, the damping component can be installed inside the hinge cup 200, thereby reducing the overall space occupied.

[0068] In an optional embodiment, the first chassis 10, the second chassis 20, and the third chassis 30 are made of iron. Iron is highly precise in stamping and drilling, and its thermal expansion and contraction helps maintain good coaxiality and fit between the perforated holes and fixing holes of each chassis layer. Furthermore, iron is relatively inexpensive, and its processing technology (such as stamping, cutting, and welding) is mature. It also possesses a certain degree of plasticity, making it suitable for processing complex structures and enabling large-scale production, thus reducing manufacturing costs.

[0069] Furthermore, in this embodiment, the first protrusion 14 and the second protrusion 15 are formed by stamping the first chassis 10. The height of the first protrusion 14 protruding from the first chassis 10 is not greater than the maximum height to which the connecting arm 40 is raised via the adjusting shaft 41, preventing the protrusion from being too high and affecting use or installation. Wherein, when the connecting arm 40 is raised via the adjusting shaft 41, the first protrusion 14 and the second protrusion 15 serve to limit the connecting arm 40.

[0070] The first protrusion 14 and the second protrusion 15 are formed by stamping, which simplifies the processing flow, avoids the addition of extra parts, and reduces manufacturing costs. Furthermore, the first protrusion 14 / second protrusion 15 are integrally formed with the first chassis 10, providing higher strength and stability, and making them less prone to loosening or damage. When the connecting arm 40 is raised, the first protrusion 14 and the second protrusion 15 can provide lateral support to the connecting arm 40, reducing the single-point stress on the adjusting shaft 41, effectively distributing the load, extending its service life, and preventing it from deforming or swaying due to stress.

[0071] In this embodiment, the sheet-stacked hinge chassis 100 further includes a first adjusting member 101. The first adjusting member 101 passes through the connecting arm 40 and is screwed to the first chassis 10. The first adjusting member 101 is used to cause relative movement between the connecting arm 40 and the first chassis 10 in a first direction, thereby adjusting the gap, height, or horizontal position between the door and the cabinet. In some embodiments, manual adjustment can be achieved using a slotted hole and bolts.

[0072] Furthermore, in this embodiment, the bottom wall of the receiving groove 13 is also provided with a protruding plate 133, and the protruding plate 133 is provided with a first threaded hole (not shown in the figure), which is used to screw into the first adjusting member 101. The height of the protruding plate 133 is higher than the bottom wall of the receiving groove 13, which facilitates contact and installation with the first adjusting member 101. Specifically, the protruding plate 133 can be formed by stamping the bottom wall of the receiving groove 13.

[0073] In an optional embodiment, the sheet-stacked hinge base 100 further includes a second adjusting member 102, which passes through the second base 20 and is screwed to the third base 30. The second adjusting member 102 is used to allow relative movement between the second base 20 and the third base 30 in a second direction, thereby adjusting the gap, height, or horizontal position between the door and the cabinet. In some embodiments, manual adjustment can be achieved using slotted holes and bolts.
