Description

Technical Field

[0001] The utility model relates to the technical field of hardware hinges, in particular to a multi-directional adjustable hinge. Background Art

[0002] Hinges are widely used in furniture. They consist of a hinge cup and a connecting base, each connected to the other. The hinge cup is fixed to the door panel, and the connecting base is mounted on a mounting base fixed to the furniture frame. A transmission assembly is installed at the junction of the hinge cup and the connecting base, and the transmission assembly is connected to a damper. This ensures smooth opening and closing of the hinge cup relative to the connecting base, while also providing a cushioning effect, ensuring normal and stable use of the furniture.

[0003] Due to the installation error between the furniture frame and the door panel, an adjustment component for adjusting the installation position is installed on the hinge arm. The adjustment component generally includes a longitudinal adjustment screw and a transverse adjustment eccentric wheel. The longitudinal adjustment screw and the transverse adjustment eccentric wheel are used to adjust the longitudinal position and transverse position between the movable frame and the hinge arm; when the longitudinal adjustment screw adjusts the fixing seat to move downward to the lowest position relative to the connecting arm, the fixing seat is pressed by the longitudinal adjustment screw, so that the transverse adjustment eccentric wheel is restricted in adjusting the fixing seat to move forward and backward in a straight line relative to the connecting arm, making it difficult to adjust the front and rear position of the hinge installation, affecting the normal use of the hinge.

[0004] Patent number 202120770100.8 is an adjustable device for a furniture buffer hinge, which is equipped with an adjustment piece movably provided along the length direction on the fixed seat, and the adjustment piece is connected with the longitudinal adjustment piece. When the longitudinal adjustment screw adjusts the adjustment piece to move upward or downward relative to the connecting arm, the rotating shaft passes through the limiting hole of the adjustment piece to connect the connecting arm, so that the adjustment piece forms a lever fulcrum for limiting the movement of the adjustment piece at a specific angle. At the same time, the adjustment piece drives the fixed seat to move up or downward. At this time, the front and rear adjustment pieces can be used to adjust the fixed seat to move forward or backward in a straight line relative to the adjustment piece. The two do not affect each other, and the longitudinal and lateral adjustments of the hinge can be adjusted smoothly; however, this structure can only be adjusted up and down and front and back, and cannot be adjusted left and right, resulting in relatively high technical requirements for installation, which cannot meet the needs of ordinary people.

[0031] refer to Figures 1 to 4A multi-directional adjustable hinge includes a hinge cup 10 mounted on a door body and a connecting base mounted on a cabinet body, wherein the hinge cup 10 and the connecting base are hingedly connected via a transmission assembly;

[0032] Among them, the connecting seat includes a connecting arm 20, a first adjustment seat 30, a second adjustment seat 40, a mounting base 50 and an adjustment mechanism, and the adjustment mechanism is used to adjust the relative position of the connecting seat in multiple dimensions; to be precise, the adjustment mechanism includes a front and rear adjustment member 60, a left and right adjustment member 70 and an up and down adjustment member 80, the first adjustment seat 30 is arranged to move forward and backward along the inner side of the connecting arm 20, and the first adjustment seat 30 and the connecting arm 20 are connected by the front and rear adjustment member 60, the second adjustment seat 40 is pivotally connected to the first adjustment seat 30, and one end of the left and right adjustment member 70 is pivotally connected to the first adjustment seat The seat 30 is threadedly connected, and the other end is rotatably connected to the second adjustment seat 40. A slide groove 501 is provided on the mounting base 50 for the second adjustment seat 40 to move left and right, and the second adjustment seat 40 is driven to move up and down by the up and down adjustment member 80. By dividing the connecting seat into a connecting arm 20, a first adjustment seat 30, a second adjustment seat 40, and a mounting base 50, the three-dimensional direction is adjusted by the front and rear adjustment members 60, the left and right adjustment members 70, and the up and down adjustment members 80 respectively. Since the adjustment process will not be restricted, the adjustment work is smoother than the traditional one.

[0033] See Figure 5 The front and rear adjustment members 60 are fixing screws, and a through slot 201 is provided on the surface of the connecting arm 20. The threaded portion of the fixing screw moves linearly along the through slot 201, and the fixing screw is threadedly connected to the first adjustment seat 30 through the threaded portion, so that the first adjustment seat 30 is fixedly connected to the connecting arm 20. To be precise, a fixing plane 203 is provided on both sides of the through slot 201, and the fixing plane 203 is flush with the top surface of the first adjustment seat 30. After loosening the fixing screw, the first adjustment seat 30 can move back and forth inside the connecting arm 20. After the installer adjusts the front and rear position of the door body to the most suitable position, tighten the fixing screw to complete the adjustment work.

[0034] Specifically, a limit block 301 is provided on the side of the first adjustment seat 30, and a limit slot 202 is provided on the side of the connecting arm 20 corresponding to the limit block 301. After the installer slightly loosens the fixing screws, the first adjustment seat 30 can move back and forth inside the connecting arm 20. At this time, the limit block 301 also moves in the limit slot 202 to prevent the first adjustment seat 30 from deviating too much from the connecting arm 20 in the adjustment state. When the fixing screws are safely screwed out, the limit block 301 leaves the limit slot 202, and the first adjustment seat 30 can be removed from the inside of the connecting arm 20.

[0035] In addition, the length of the through slot 201 is determined according to the positions of the front and rear adjusting member 60 , the left and right adjusting member 70 , and the upper and lower adjusting member 80 , ensuring that a tool can be inserted into the through slot for adjustment.

[0036] See Figure 6-8 The left and right adjusting members 70 are adjusting screws, and a rotating member 90 is pivotally connected to the second adjusting seat 40. One end of the adjusting screw is axially rotatable on the rotating member 90, and the other end is threadedly connected to the first adjusting seat 30. To be precise, one end of the second adjusting seat 40 is pivotally connected to the first adjusting seat 30 through an axle pin, and the other end of the second adjusting member is pivotally connected to the rotating member 90. One end of the left and right adjusting member 70 is riveted to the rotating member 90, and its threaded portion is threadedly connected to the first adjusting seat 30. By twisting the left and right adjusting members 70, its threaded portion moves in a linear direction on the first adjusting seat 30, so that the positions of the rotating member 90, the second adjusting seat 40 and the first adjusting seat 30 are relatively moved left and right, thereby realizing left and right position adjustment.

[0037] In a preferred embodiment, Figure 9 As shown, a U-shaped groove is provided on the rotating member 90, and one end of the left and right adjusting members 70 is rotated and engaged on the U-shaped groove, and the threaded parts of the left and right adjusting members 70 are threadedly connected to the first adjusting seat 30. This structure is more convenient during installation. It is only necessary to engage the ends of the left and right adjusting members 70 in the U-shaped groove. It is a common adjustment structure for adjusting hinges. By changing the adjustment structure between the original connecting arm 20 and the first adjustment seat 30 to between the first adjustment seat 30 and the second adjustment seat 40, interference in hinge adjustment is prevented.

[0038] See Figure 10-12 The upper and lower adjusting members 80 include a driving portion 801, an actuating portion 802 and an eccentric portion 803 which are arranged in sequence. The second adjusting seat 40 is provided with a long hole 401 for the actuating portion 802 to move linearly back and forth. The eccentric portion 803 is inserted into the mounting base 50, so that when the driving portion 801 drives the eccentric portion 803 to rotate, the actuating portion 802 drives the second adjusting seat 40 to move up and down along the slide groove 501 of the mounting base 50. To be precise, the upper and lower adjusting members 80 are eccentric adjusting rivets, and the eccentric portion 803 of the eccentric adjusting rivet is arranged on the mounting base 50. By rotating the eccentric adjusting rivet, the actuating portion 802 moves linearly back and forth along the long hole 401. At the same time, the eccentric portion 803 drives the adjusting seat to move left and right, thereby adjusting the installation position of the hinge in the left and right directions.

[0039] Specifically, the mounting base 50 and the second adjustment seat 40 are connected by rivets. Long grooves 502 are provided at both ends of the slide groove 501. The long grooves 502 are vertically arranged in the up and down directions. The rivets move linearly along the long grooves 502 to ensure the connection strength between the mounting base 50 and the second adjustment seat 40.

[0040] Specifically, a guide groove 503 is also provided on the slide groove 501, and a guide block 402 is provided on the rear surface of the second adjustment seat 40. To be precise, the guide groove 503 is a long groove with a V-shaped cross-section, and the guide block 402 has a corresponding V-shaped cross-section, so that the guide block 402 and the guide groove 503 both play a better guiding role. When the guide block 402 moves vertically along the guide groove 503 in the up and down directions, the linear motion consistency of the mounting base 50 on the second adjustment seat 40 is ensured.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
