Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to door hinges used for mounting on profiles. Background Technology

[0002] In the current furniture industry, cabinet doors are generally installed using hinged hinges. These hinges are mostly fixed to the cabinet wall via hinge brackets, making them fixed doors. With the design upgrades in modern furniture, there is a need for movable doors. Traditional cabinet-mounted doors are difficult to move, so frame-mounted doors are a more practical option. Because of the need for smooth door closure and adjustable position, traditional hinges typically house the damping buffer and position adjustment mechanism in the hinge bracket. Clearly, this type of hinge is unsuitable for frame mounting. Therefore, it is necessary to develop a hinge suitable for frame mounting. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a door hinge suitable for profile installation.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: A door hinge suitable for profile installation includes a hinge seat for fixing the frame, a drive hinge arm and a support hinge arm respectively hinged to the hinge seat, a connecting rod seat respectively hinged to the drive hinge arm and the support hinge arm, a torsion spring for driving the drive hinge arm to swing, a hinge cup seat fixed to the connecting rod seat for installing the door leaf, and a hydraulic damper for buffering the swing of the hinge cup seat when closing the door. The hinge seat is characterized in that: the hinge seat is slidably installed with the frame along the length direction of the frame and is fastened with threaded fasteners; the connecting rod seat forms a plug-in seat that slidably inserts into the cup body of the hinge cup seat in the horizontal direction of the door leaf; the plug-in seat rotatably installs an eccentric rotating body for moving the hinge cup seat; a sliding cavity is formed between the plug-in seat and the hinge cup seat to accommodate the sliding extension and retraction of the hydraulic damper; the cylinder of the hydraulic damper forms a stop tooth extending towards the hinge end of the connecting rod seat of the drive hinge arm, and the hinge end forms a tooth that pushes the stop tooth to compress the tooth of the hydraulic damper; the connecting rod seat and the hinge cup seat are fixed together by threaded fasteners.

[0005] Based on the above, the bottom of the cup body of the hinge cup holder has a mounting hole for placing an eccentric rotating body and a slot extending in a U-shape from the mounting hole along the trajectory of the eccentric part of the eccentric rotating body. The mounting hole is fitted with a cover, and a boss is formed inside the cover that extends into the mounting hole to prevent the eccentric part from returning to the mounting hole.

[0006] Based on the above, a threaded adjustment device for pushing the hinge seat to move is installed at the lower end of the frame.

[0007] The beneficial effects of this utility model are as follows: Since the hinge seat of the door hinge is designed to be slidably and securely installed with the frame of the profile, the device for adjusting the vertical position of the door leaf can be installed on the frame, while the device for adjusting the horizontal position and the hydraulic damper are installed on the hinge cup seat. Thus, the door hinge of this utility model is very suitable for installation with frame profiles. Attached Figure Description

[0009] Figure 2 This is an exploded view of the door hinge applicable to profile installation according to this utility model. Detailed Implementation

[0010] like Figure 1-2 As shown, a door hinge suitable for profile installation includes a hinge base 2 for fixing a frame 1, a drive hinge arm 3 and a support hinge arm 4 respectively hinged to the hinge base 2, a connecting rod seat 5 respectively hinged to the drive hinge arm 3 and the support hinge arm 4, a torsion spring 6 for driving the drive hinge arm 3 to swing, a hinge cup seat 8 fixed to the connecting rod seat 5 for mounting the door leaf, and a hydraulic damper 9 for buffering the swing of the hinge cup seat 8 when closing the door. The door hinge adopts a traditional four-bar hinge structure. The torsion spring 6 is installed on the hinge axis between the drive hinge arm 3 and the hinge base 2, driving and responding to the rotation of the drive hinge arm 3. Whether the door leaf is fully open or fully closed, the drive hinge arm 3 will complete one reciprocating swing, and the torsion spring 6 will correspondingly complete one compression and then relaxation process. The door leaf is in the half-open position, which is the dead point position of the four-bar hinge. The torsion spring 6 is compressed in response to the first half of the opening and closing of the door leaf, and relaxes after passing the dead point position to drive the door leaf to continue opening or closing. The hydraulic damper 9 is used to buffer the closing of the door leaf 1.

[0011] Typically, door hinges need to be adjustable in both horizontal and vertical directions to adjust the position of the door leaf in both directions. In this embodiment, the hinge seat 2 is slidably installed with the frame 1 along the length of the frame 1 and is fastened with threaded fasteners 10. The connecting rod seat 5 forms a plug seat 5.1 that is slidably inserted into the cup body of the hinge cup seat 8 in the horizontal direction of the door leaf. The plug seat 5.1 is rotatably mounted with an eccentric rotating body 11 for moving the hinge cup seat 8. A sliding cavity Q is formed between the plug seat 5.1 and the hinge cup seat 8 to accommodate the sliding extension and retraction of the hydraulic damper 9. The cylinder of the hydraulic damper 9 forms a stop tooth 9.1 extending toward the hinge end of the hinge connecting rod seat 5 that drives the hinge arm 3, and the hinge end forms a stop tooth 9.1 that compresses the tooth 3.1 of the hydraulic damper 9. The connecting rod seat 5 and the hinge cup seat 8 are fixed together by threaded fasteners 12. For horizontal installation, simply rotate the eccentric rotating body 11 with a tool. The eccentric part 11.1 of the eccentric rotating body 11 will move the hinge cup seat 8 horizontally, thereby adjusting the horizontal position of the door leaf. After adjusting to the appropriate position, it is fixed by tightening the threaded fastener 12. For vertical installation, it is fixed by threaded fastener 10.

[0012] In actual production, the issue of facilitating the installation of the eccentric rotating body 11 also needs to be considered. Since the eccentric rotating body 11 is axially fixed by being clamped between the hinge cup seat 8 and the insertion seat 5.1, and the eccentric rotating body 11 is usually rotated and adjusted on the insertion seat 5.1 side, the shaft hole 5.1.1 of the insertion seat 5.1 for rotatably installing the eccentric rotating body 11 is designed as a stepped hole with a narrow opening, allowing only the insertion of an adjusting tool. Furthermore, since the hinge cup seat 8 and the insertion seat 5.1 are slidably inserted in a direction perpendicular to the axial direction of the eccentric rotating body 11, the eccentric rotating body 11 cannot be installed first. The insertion and installation of the hinge cup seat 8 and the insertion seat 5.1 must be completed first, and then the installation of the eccentric rotating body 11 can be considered. To facilitate the installation of the eccentric rotating body 11, this embodiment has a mounting hole 8.1 at the bottom of the cup body of the hinge cup seat 8 for placing the eccentric rotating body 11, and a slot 8.2 extending in a U-shape from the mounting hole 8.1 along the rotation trajectory of the eccentric part 11.1 of the eccentric rotating body 11. The mounting hole 8.1 is fitted with a cover 13, and a boss 13.1 is formed inside the cover 13, extending into the mounting hole 8.1 to prevent the eccentric part 11.1 from returning to the mounting hole 8.1. During installation, after the hinge cup seat 8 and the plug seat 5.1 are plugged in, the eccentric rotating body 11 can be installed from the mounting hole 8.1 into the shaft hole of the plug seat 5.1 on the bottom side of the hinge cup seat 8. Then, the eccentric rotating body 11 is rotated so that the eccentric part 11.1 rotates into the slot 8.2. Finally, the cover 13 is put on. At this time, the boss 13.1 of the cover 13 will prevent the eccentric part 11.1 from returning to the mounting hole 8.1, and always maintain a push-fit relationship with the hole wall of the slot 8.2.

[0013] To facilitate vertical adjustment, a threaded adjustment device 14 for pushing and moving the hinge 2 is installed at the lower end of the frame 1. The hinge 2 and the threaded adjustment device 14 are installed on the frame 1 using a conventional profile fastening method, where the frame 1 uses a profile with a T-slot, and a nut block 15 for fastening with threaded fasteners is inserted into the T-slot. The threaded adjustment device 14 is a conventional threaded push-type structure, which will not be described in detail here. The vertical position of the door leaf can be adjusted by rotating the threaded part of the threaded adjustment device 14.
