Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a hinge base fastening structure and a hinge. Background Technology

[0002] A hinge is a common hardware accessory used in furniture doors (such as cabinet doors, cupboard doors, etc.) to enable the door to open and close. Some hinges also have a buffer function, allowing the door to close slowly and smoothly, reducing collisions and noise. A hinge generally consists of several parts, with the base mounting the hinge to a fixed door frame. To allow for fine adjustments to the installation angle and height between the door frame and the furniture door, eccentric nails and auxiliary brackets are typically used to fine-tune the base.

[0003] When the eccentric pin is rotated, its off-center nature causes a slight vertical displacement of the movable seat. For example, if the eccentric pin is rotated in a certain direction, the movable seat will rise or fall slightly under the action of the auxiliary frame, thus achieving fine-tuning. However, due to the gaps between the fixed base, the auxiliary frame, the movable seat, and the rivets used for fastening, the auxiliary frame may rotate horizontally between the fixed base and the movable seat when the eccentric pin rotates. This can cause instability in the movable seat, resulting in shaking or flipping, and loosening of the hinge base. Utility Model Content

[0004] To address the technical problem of loosening of the hinge base due to rotation of the auxiliary frame during fine-tuning using eccentric pins, this utility model provides a hinge base fastening structure and a hinge itself. The specific solution is as follows:

[0005] In a first aspect, this utility model provides a hinge base fastening structure, including a fixed base. The back of the fixed base is connected to a door or window, and the top surface is equipped with an adjustment accessory. The adjustment accessory includes an auxiliary frame, a movable seat, and an eccentric nail. The movable seat is connected to the fixed base. The auxiliary frame is disposed between the movable seat and the fixed base and is mounted on the fixed base by the eccentric nail. The top surface of the fixed base is provided with a locking seat for guiding the horizontal displacement of the auxiliary frame and restricting the horizontal rotation of the auxiliary frame. The auxiliary frame is provided with a fastener that matches the locking seat. The fastener engages with the locking seat to limit the horizontal rotation of the auxiliary frame mounted on the fixed base.

[0006] Furthermore, the card holder includes a first protrusion, which protrudes upward from the outer edge of the fixed base. The fastening of the auxiliary frame includes a clearance groove disposed at the bottom of the auxiliary frame and corresponding to the first protrusion. The two walls of the clearance groove abut against the two sides of the first protrusion, respectively.

[0007] Furthermore, the fixed base is provided with an eccentric hole corresponding to the eccentric nail, and the auxiliary frame is provided with a guide groove corresponding to the eccentric hole. The auxiliary frame is rotatably mounted on the fixed base through the cooperation of the eccentric nail, the guide groove and the eccentric hole.

[0008] Furthermore, the card holder also includes a second boss; the second boss is disposed on the side of the eccentric hole away from the first boss and is aligned with the first end of the auxiliary frame, and the second boss abuts against the first end of the auxiliary frame.

[0009] Furthermore, the second boss protrudes upward along the outer edge of the fixed base, and the edge of the second boss is provided with a first bending portion, which is formed by bending towards the central axis of the fixed base at the position where the second boss is aligned with the first end of the auxiliary frame.

[0010] Furthermore, the card holder also includes a third protrusion; the third protrusion is disposed on the side of the first protrusion away from the eccentric hole, and a limiting groove is formed between the third protrusion and the first protrusion; the auxiliary frame is correspondingly provided with a limiting strip, the limiting strip is embedded in the limiting groove, and its two sides abut against the first protrusion and the third protrusion respectively.

[0011] Furthermore, there are two of each of the first, second, and third protrusions; the two first / second / third protrusions protrude along the two outer edges of the fixed base and are mirror-symmetrically arranged along the central axis of the fixed base.

[0012] Furthermore, the two outer edges of the first boss are bent toward the central axis of the fixed base to form a second bend, and a through groove for assembling fasteners is formed between the two first bosses.

[0013] Furthermore, at least one end of the fixed base is provided with an extension portion, which protrudes from the outer edge of the fixed base in a direction away from the central axis; the bottom of the first boss is provided with an expansion through hole, and the bottom of the expansion through hole is provided with an expansion plane for expanding the contact area of ​​the back of the fixed base.

[0014] On the other hand, this embodiment also provides a hinge, which includes the hinge-type base fastening structure described above.

[0015] This utility model uses the locking mechanism of the fixed base and the fastener on the auxiliary frame to limit the rotation of the auxiliary frame when the base is finely adjusted by adjusting the eccentric pin. This prevents the base from flipping or becoming unstable due to the deflection of the auxiliary frame, increases the reliability and sturdiness of the hinge, greatly reduces the safety hazard of the hinge being damaged due to structural loosening, and improves the user experience.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0033] Example 1:

[0034] Please see Figure 1-6 This embodiment provides a hinge base fastening structure, which specifically includes a fixed base 10 and adjustment accessories. The fixed base 10 is used to connect with doors and windows and to support the assembly of other hinge components. The two can be fixed by fasteners. For example, the bottom surface of the fixed base 10 is provided with multiple mounting holes. Fasteners pass through the holes and are installed on the door frame of the furniture door, thereby connecting the fixed base 10 to the door frame.

[0035] Adjustment accessories are located on the front of the fixed base 10 and are used to fine-tune the installation angle and height of the furniture door by rotating the eccentric nail 40. The adjustment accessories include an auxiliary frame 20, a movable base 30, and the eccentric nail 40. The movable base 30 is connected to the fixed base 10 by riveting. For example, the movable base 30 and the fixed base 10 each have multiple corresponding through holes on their sides, and the rivets pass through both the movable base 30 and the fixed base 10 from one side to complete the connection. The advantage of this connection is that the relative distance between the movable base 30 and the fixed base 10 can be adjusted by adjusting the eccentric nail 40, thereby enabling fine-tuning of the installation angle and height between the base and the door / window. The auxiliary frame 20 is located between the movable base 30 and the fixed base 10 and is mounted on the fixed base 10 by the eccentric nail 40. It is used to adjust the horizontal relative position between the movable base 30 and the fixed base 10 by rotating the eccentric nail 40.

[0036] As a key feature of this embodiment, the top surface of the fixed base 10 is provided with a retaining seat. This retaining seat is mainly used to restrict the horizontal rotation of the auxiliary frame 20 during the adjustment process, and also to guide the horizontal translation of the auxiliary frame 20. The auxiliary frame 20 is provided with corresponding fasteners that match the retaining seat. In the assembled state, the auxiliary frame 20 is mounted on the fixed base 10, and the fasteners of the auxiliary frame 20 engage with the retaining seat. When the eccentric pin 40 is adjusted, the auxiliary frame 20 moves horizontally up and down relative to the fixed base 10, allowing for fine-tuning of the base. During adjustment, the auxiliary frame 20 is limited by the retaining seat and cannot rotate horizontally relative to the fixed base 10, thus improving the stability of the base.

[0037] Specifically, the following provides the specific positioning method for the dinettes.

[0038] Preferably, the mounting bracket includes a first protrusion 11, which is disposed on the top surface of the fixed base 10. The first protrusion 11 protrudes upward from the outer edge of the fixed base 10. The locking mechanism of the auxiliary frame 20 includes a clearance groove 21 disposed at the bottom of the auxiliary frame 20 and corresponding to the first protrusion 11. The "corresponding" aspect means that the size of the clearance groove 21 matches the size of the first protrusion 11. The auxiliary frame 20 can be locked onto the fixed base 10 through the clearance groove 21. When the eccentric pin 40 rotates and causes the auxiliary frame 20 to move horizontally on the fixed base 10, the rotation of the auxiliary frame 20 is limited by the abutment between the groove wall on the opposite side of the clearance groove 21 and the two sides of the first protrusion 11. The advantage of this assembly method is that the abutment between the clearance groove 21 and the two sides of the first protrusion 11 limits the rotation of the auxiliary frame 20 in two horizontal directions, ensuring that the auxiliary frame 20 can only move horizontally when the eccentric pin 40 is adjusted.

[0039] Preferably, the wall of the clearance groove 21 and the side of the first boss 11 are provided with a mating surface. This mating surface can be set as a plane, or other mating surfaces that can achieve the solution of this embodiment can be adjusted as needed. Preferably, the wall of the clearance groove 21 can serve as its mating surface, and the corresponding side wall of the first boss 11 can serve as its mating surface. In the connection relationship, the clearance groove 21 is embedded in the first boss 11 through the corresponding mating surface, and when the auxiliary frame 20 moves horizontally, it limits the horizontal rotation of the auxiliary frame 20.

[0040] In the structure of the fixed base 10, the fixed base 10 has an eccentric hole 14 corresponding to the eccentric nail 40, and the auxiliary frame 20 is provided with a guide groove 22 corresponding to the eccentric hole. The auxiliary frame 20 is rotatably mounted on the fixed base 10 through the cooperation of the eccentric nail 40, the guide groove 22, and the eccentric hole. During installation, the eccentric hole 14 of the fixed base 10 and the guide groove 22 on the auxiliary frame 20 are aligned. The eccentric nail 40 passes through the guide groove 22 and is placed in the eccentric hole 14. Finally, the bottom end of the eccentric nail 40 is flattened to assemble the auxiliary frame 20 onto the fixed base 10. At the same time, the fixed base 10 limits the auxiliary frame 20 through the cooperation of the retaining seat and the snap fastener. When the eccentric nail 40 is rotated, the eccentric nail 40 drives the auxiliary frame 20 to move horizontally relative to the fixed base 10 through the guide groove 22, thereby driving the relative translation of the movable seat 30 and the fixed base 10. It is worth noting that in this embodiment, this horizontal translation refers to the directional movement in the vertical direction of the central axis of the fixed base 10.

[0041] Of course, more preferably, there are two first protrusions 11, which protrude along the two outer edges of the fixed base 10 and are mirror-symmetrically arranged along the central axis of the fixed base 10. Correspondingly, the width of the side wall of the auxiliary frame 20 and the width of the clearance groove 21 correspond to the two first protrusions 11. The design of two first protrusions 11 can increase the contact points used to limit the rotation of the auxiliary frame 20, thereby making the rotation limit of the auxiliary frame 20 more reliable.

[0042] Furthermore, the two outer edges of the first boss 11 are bent towards the central axis of the fixed base 10 to form second bent portions 111. These second bent portions 111 increase the contact area between the first boss 11 and the auxiliary frame 20, thereby preventing excessive stress and deformation of the first boss 11 or the wall of the clearance groove 21 during adjustment. Simultaneously, the auxiliary frame 20 will translate relative to the fixed base 10 during adjustment. The design of the second bent portions 111 prevents the wall of the clearance groove 21 from detaching from the first boss 11, thus reducing the risk of disengagement. On the other hand, a through groove for assembling fasteners is formed between the two first bosses 11. This design saves space in the fixed base 10, providing rotational limits without increasing the length of the fixed base 10, thus saving processing costs.

[0043] In this embodiment, the first boss 11 of the fixed base 10 and the clearance groove 21 on the auxiliary frame 20 cooperate to limit the rotation of the auxiliary frame 20 when the eccentric screw 40 is adjusted for fine-tuning of the base. This prevents the base from flipping or becoming unstable due to the deflection of the auxiliary frame 20, increasing the reliability and robustness of the hinge, greatly reducing the safety hazard of hinge damage due to structural loosening, and improving the user experience. Furthermore, to improve the rotation limiting effect of the auxiliary frame 20 and enhance its adjustment effect, this embodiment also includes a second boss 12 and a third boss 13.

[0044] Regarding the second boss 12, the second boss 12 is located on the side of the eccentric hole 14 away from the first boss 11 and is aligned with the first end 23 of the auxiliary frame 20. The second boss 12 abuts against the first end 23 of the auxiliary frame 20, which also serves to restrict the horizontal rotation of the auxiliary frame 20 relative to the fixed base 10.

[0045] Specifically, the second protrusion 12 protrudes upward along the outer edge of the fixed base 10, and a first bending portion 121 is provided at the edge of the second protrusion 12, which abuts against the first end 23 of the auxiliary frame 20. The first bending portion 121 is formed by bending towards the central axis of the fixed base 10 at the position where the second protrusion 12 and the first end 23 of the auxiliary frame 20 are aligned. The function of the first bending portion 121 is similar to that of the second bending portion 111, mainly used to improve the stability of the limiting function, increase the force-bearing area, and improve the abutment reliability.

[0046] Regarding the third boss 13, the third boss 13 is located on the side of the first boss 11 away from the eccentric hole 14, and a limiting groove 15 is formed between the third boss 13 and the first boss 11. The auxiliary frame 20 is correspondingly provided with a limiting strip 24, the size of which matches the limiting groove 15. The limiting strip 24 is embedded in the limiting groove 15, and its two sides abut against the first boss 11 and the third boss 13 respectively.

[0047] Preferably, two second bosses 12 and two third bosses 13 are provided, with the two second bosses 12 protruding along the two outer edges of the fixed base 10 and mirror-symmetrically arranged along the central axis of the fixed base 10. Similarly, the two third bosses 13 also protrude along the two outer edges of the fixed base 10 and are mirror-symmetrically arranged along the central axis of the fixed base 10. The advantage of this arrangement is similar to that of the first boss 11 protruding from the two outer edges of the fixed base 10, mainly to improve the limiting effect on the auxiliary frame 20, and at the same time make the assembly of the auxiliary frame 20 on the fixed base 10 more stable and reliable.

[0048] For a specific implementation method, please refer to [link / reference]. Figure 1-6The auxiliary frame 20 has a clearance groove 21 and a limiting strip 24 at its bottom. When the auxiliary frame 20 is assembled on the fixed base 10, the clearance groove 21 fits onto the first protrusion 11, and the limiting strip 24 is embedded in the limiting groove 15 of the fixed base 10. This nesting method improves the stability of the auxiliary frame 20 and provides better rotation limiting effect. During the rotation adjustment of the eccentric nail 40, the auxiliary frame 20 moves horizontally relative to the fixed base 10 under the action of the aforementioned limiting structure, thereby moving the movable base 30 to adjust the installation angle and height between the cabinet and the door panel. This hinge-type base fastening structure can avoid or reduce the rotation of the auxiliary frame 20, greatly improving the reliability of the base.

[0049] On the other hand, the bottom edge of the fixed base is usually rounded to prevent scratches and distribute stress. However, this design reduces the contact area between the fixed base and the furniture frame, making the flat base prone to loosening and flipping over over time.

[0050] Therefore, as a preferred embodiment, please refer to Figure 4 and Figure 5 At least one end of the fixed base 10 is provided with an extension portion 16, which protrudes from the outer edge of the fixed base 10 in a direction away from the central axis. This design increases the contact area between the fixed base 10 and the furniture door frame at the end, thereby preventing or reducing the possibility of tipping over. For the same purpose, the bottom of the first boss 11 is provided with an expansion through hole 17, and the bottom of the expansion through hole 17 is provided with an expansion plane 18 for expanding the contact area on the back of the fixed base 10. In a preferred embodiment, the fixed base 10 is provided with extension portions 16 at both ends, and the extension portions 16 at the ends of the fixed base 10 extend away from the central axis on both sides.

[0051] Example 2:

[0052] This embodiment also provides a hinge for installing furniture doors. Specifically, the hinge is equipped with the hinge base fastening structure described in Embodiment 1. Preferably, the hinge can be a buffer hinge, used to enable the furniture door to open and / or close slowly and smoothly.

[0053] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
