Description

Technical Field

[0001] The present invention relates to the technical field of furniture hardware fittings, and specifically relates to a hinge with an optimized adjustment structure. Background Art

[0002] Refer to Figure 7 , the hinge includes a connecting arm and an adjusting seat. An adjusting member is provided between the connecting arm and the adjusting seat. The adjusting member can be an eccentric nail or an eccentric rotating disk. When the adjusting member is an eccentric nail, the connecting arm and the adjusting member are cooperatively connected through a first positioning rotating assembly; a second positioning rotating assembly is further provided between the adjusting seat and the adjusting member, and the adjusting seat and the adjusting member are cooperatively connected through the second positioning rotating assembly; when the adjusting member moves, it is positioned and rotated between the connecting arm and the adjusting seat through the first positioning rotating assembly and / or the second positioning rotating assembly; wherein, the first positioning rotating assembly includes a positioning groove provided on the connecting arm and a positioning disk provided on the adjusting member. When the adjusting member rotates, the positioning disk is limited to rotate on the inner wall surface of the positioning groove, and the anti-rotation of the adjusting member is realized through the cooperation between the inner wall surface of the positioning groove and the positioning disk. Therefore, when the adjusting member rotates to a certain angle, the outer side surface of the positioning disk acts on the inner wall surface of the positioning groove. However, if the user twists the adjusting member with a large force, the outer side surface of the positioning disk is likely to cross the inner wall surface of the positioning groove, causing the limit adjustment of the adjusting member to fail. And when the user twists the adjusting member with excessive force, the positioning groove on the connecting arm is likely to be deformed.

[0003] The above structure refers to a stable adjustment structure of a furniture hinge disclosed in Chinese Patent No. 202111630865.2. Summary of the Invention

[0004] The purpose of the present invention is to provide a hinge with an optimized adjustment structure. A limit adjustment assembly is provided between the adjusting seat and the adjusting member; when the adjusting member moves, it drives the adjusting seat to be limited to move on the accommodating cavity of the connecting arm, and the adjusting member is limited to move on the adjusting seat through the limit adjustment assembly. The limit adjustment structure is cancelled at the cooperation position between the connecting arm and the adjusting member, solving the problem that the positioning groove on the connecting arm is likely to be deformed when the user twists the adjusting member with excessive force, and at the same time avoiding the wear phenomenon of the adjusting member, ensuring the original processing and matching accuracy of the adjusting member and the connecting arm, and prolonging the adjustment service life of the product.

[0005] The purpose of the present invention is achieved as follows:

[0006] A hinge with an optimized adjustment structure includes a movable seat, a connecting arm, an adjustment seat, and an adjustment member. The movable seat is cooperatively connected to the connecting arm. The adjustment seat is movably arranged on the connecting arm. There is a receiving cavity for installing the adjustment seat on the connecting arm. The adjustment seat is limit-mounted on the receiving cavity. The connecting arm and the adjustment seat are respectively cooperatively connected to the adjustment member. A limit adjustment assembly is provided between the adjustment seat and the adjustment member. When the adjustment member moves, it drives the adjustment seat to be limitedly movable on the receiving cavity of the connecting arm, and the adjustment member is limitedly movable on the adjustment seat through the limit adjustment assembly. The cooperation at the joint between the connecting arm and the adjustment member is provided without a limit adjustment structure, solving the problem that the positioning groove on the connecting arm is prone to deformation when the user twists the adjustment member with excessive force, and at the same time avoiding wear of the adjustment member, ensuring the original processing and fitting accuracy of the adjustment member and the connecting arm, and extending the adjustment service life of the product.

[0007] The limit adjustment assembly is a stepped or stepless limit adjustment assembly, so as to realize the stepped or stepless limit adjustment of the adjustment member through the limit adjustment assembly. Multiple design methods meet the needs of users. The advantage of stepless limit adjustment is that when the user twists the adjustment member, the adjustment is unobstructed and smooth. The advantage of stepped limit adjustment is that when the user twists the adjustment member, the adjustment member rotates step by step to prevent excessive adjustment (too large adjustment), and the user can adjust step by step according to the actual situation.

[0008] The limit adjustment assembly includes a limit groove part and an acting part. When the adjustment member moves, the acting part is relatively limit-movable on the limit groove part, and acts on the limit groove part in a stepped or stepless manner, thereby realizing the stepped or stepless limit adjustment of the adjustment member.

[0009] The limit groove part includes a first limit surface and a second limit surface. One end of the acting part is limited between the first limit surface and the second limit surface.

[0010] The acting part includes an acting surface limited between the first limit surface and the second limit surface, and the acting surface acts on the first limit surface and the second limit surface in a stepped or stepless manner.

[0011] The limit groove part includes a first closed end and a second closed end. When the adjustment member moves, the acting part acts on the first closed end or the second closed end to limit the adjustment member to be movable on the adjustment seat. When the acting part contacts the first closed end or the second closed end, the adjustment member cannot be twisted anymore, and the adjustment member reaches the maximum rotation stroke in the clockwise or counterclockwise direction.

[0012] The receiving cavity includes a first inner side surface, a second inner side surface, and a third inner side surface. The receiving cavity limits and wraps the adjustment seat through the first inner side surface, the second inner side surface, and the third inner side surface, so that the adjustment seat is limit-mounted on the receiving cavity. The receiving cavity forms a receiving cavity with an open bottom through the first inner side surface, the second inner side surface, and the third inner side surface, which is convenient for installing the adjustment seat.

[0013] When the adjusting member moves and drives the adjusting seat to move, the adjusting seat is linearly limited on the accommodating cavity through the second inner side surface and / or the third inner side surface, ensuring that the adjusting seat does not shift left and right when moving.

[0014] A first positioning and rotating assembly is provided between the connecting arm and the adjusting member, and the connecting arm and the adjusting member are connected in cooperation through the first positioning and rotating assembly; a second positioning and rotating assembly is also provided between the adjusting seat and the adjusting member, and the adjusting seat and the adjusting member are connected in cooperation through the second positioning and rotating assembly; when the adjusting member moves, it is positioned and rotated between the connecting arm and the adjusting seat through the first positioning and rotating assembly and / or the second positioning and rotating assembly.

[0015] The adjusting member rotates in a stepped or stepless manner between the connecting arm and the adjusting seat through the first positioning and rotating assembly and / or the second positioning and rotating assembly to achieve stepped or stepless adjustment of the adjusting member.

[0016] The beneficial effects of the present invention are as follows:

[0017] A limit adjustment assembly is provided between the adjusting seat and the adjusting member; when the adjusting member moves, it drives the adjusting seat to be limitedly moved on the accommodating cavity of the connecting arm, and the adjusting member is limitedly moved on the adjusting seat through the limit adjustment assembly, canceling the limit adjustment structure at the mating part between the connecting arm and the adjusting member, solving the problem that the positioning groove on the connecting arm is prone to deformation when the user twists the adjusting member with excessive force, and at the same time avoiding wear of the adjusting member, ensuring the original machining and mating accuracy of the adjusting member and the connecting arm, and prolonging the adjustment service life of the product.

[0018] The limit adjustment assembly is a stepped or stepless limit adjustment assembly, and various design methods meet the user's needs. The advantage of stepless limit adjustment is that there is no hindrance and the adjustment is smooth when the user twists the adjusting member. The advantage of stepped limit adjustment is that when the user twists the adjusting member, the adjusting member rotates step by step, preventing excessive adjustment (too large adjustment), and the user can make step-by-step adjustment according to the actual situation.

The movable seat 1 is cooperatively connected with the connecting arm 2. The adjusting seat 3 is movably arranged on the connecting arm 2. A receiving cavity 5 for installing the adjusting seat 3 is provided on the connecting arm 2. The adjusting seat 3 is limitedly installed on the receiving cavity 5. The connecting arm 2 and the adjusting seat 3 are respectively cooperatively connected with the adjusting member 4. A limiting adjustment assembly 6 is provided between the adjusting seat 3 and the adjusting member 4. When the adjusting member 4 moves, it drives the adjusting seat 3 to be limitedly movable on the receiving cavity 5 of the connecting arm 2, and the adjusting member 4 is limitedly movable on the adjusting seat 3 through the limiting adjustment assembly 6.

[0028] In this embodiment, the movable seat 1 is hinged to the connecting arm 2 through a hinge arm assembly.

[0029] In this embodiment, the hinge further includes a bottom plate cooperatively connected with the adjusting seat 3. For the specific connection structure, damping structure, and elastic structure of the hinge, refer to a stable adjustment structure of a furniture hinge disclosed in Chinese Patent No. 202111630865.2, which will not be elaborated here.

[0030] The limiting adjustment assembly 6 is a stepped or stepless limiting adjustment assembly, so as to realize the stepped or stepless limiting adjustment of the adjusting member 4 through the limiting adjustment assembly 6.

[0031] The limiting adjustment assembly 6 includes a limiting groove portion 7 and an acting portion 8. When the adjusting member 4 moves, the acting portion 8 is limitedly movable relative to the limiting groove portion 7, and acts on the limiting groove portion 7 in a stepped or stepless manner through the acting portion 8, thereby realizing the stepped or stepless limiting adjustment of the adjusting member 4.

[0032] The limiting groove portion 7 includes a first limiting surface 9 and a second limiting surface 10. One end of the acting portion 8 is limited between the first limiting surface 9 and the second limiting surface 10.

[0033] In this embodiment, one end of the acting portion 8 can contact the inner bottom wall surface of the limiting groove portion 7 to increase the friction during adjustment and prevent over-adjustment, or one end of the acting portion 8 can be suspended above the inner bottom wall surface of the limiting groove portion 7 to reduce the friction generated during adjustment. Here, a stepless limiting adjustment assembly is applicable.

[0034] The acting part 8 includes an acting surface 13 limited between a first limiting surface 9 and a second limiting surface 10, and the acting surface 13 acts on the first limiting surface 9 and the second limiting surface 10 in a stepwise or stepless manner.

[0035] In this embodiment, when the limiting adjustment assembly 6 is a stepless limiting adjustment assembly, the acting part 8 is cylindrical, the outer surface of the acting surface 13 is arc-shaped, and the limiting groove part 7 is an arc-shaped groove.

[0036] In this embodiment, when the limiting adjustment assembly 6 is a stepped limiting adjustment assembly, a plurality of first meshing teeth are provided on the first limiting surface 9 or the second limiting surface 10, and a plurality of second meshing teeth are provided on the outer surface of the acting surface 13. The first meshing teeth and the second meshing teeth are meshed, so that the acting surface 13 of the acting part 8 acts on the first limiting surface 9 and the second limiting surface 10 in a stepwise or stepless manner, and the limiting groove part 7 is an arc-shaped groove.

[0037] In this embodiment, when the limiting adjustment assembly 6 is a stepped limiting adjustment assembly, a plurality of first arc-shaped protrusions are provided on the first limiting surface 9 or the second limiting surface 10 at intervals, and a plurality of second arc-shaped protrusions are provided on the acting surface 13 at intervals.

[0038] The limiting groove part 7 includes a first closed end 11 and a second closed end 12. When the adjusting member 4 moves, the acting part 8 acts on the first closed end 11 or the second closed end 12, so that the adjusting member 4 is limited to move on the adjusting seat 3.

[0039] When the adjusting member 4 rotates along the direction of the first closed end 11 and when the acting part 8 acts on the first closed end 11, the adjusting member 4 cannot continue to rotate along the direction of the first closed end 11. When the adjusting member 4 rotates along the direction of the second closed end 12 and when the acting part 8 acts on the second closed end 12, the adjusting member 4 cannot continue to rotate along the direction of the second closed end 12, so as to limit the rotation angle of the adjusting member 4. That is, even if the user twists the adjusting member 4 with the maximum force, the adjusting member 4 cannot continue to twist, thereby effectively realizing the limiting adjustment function of the adjusting member 4.

[0040] The accommodating cavity 5 includes a first inner side surface 14, a second inner side surface 15, and a third inner side surface 16. The accommodating cavity 5 limits and wraps the adjusting seat 3 through the first inner side surface 14, the second inner side surface 15, and the third inner side surface 16, so that the adjusting seat 3 is limited and installed on the accommodating cavity 5.

[0041] In this embodiment, the adjusting seat 3 is positioned left and right between the second inner side surface 15 and the third inner side surface 16.

[0042] When the adjusting member 4 moves and drives the adjusting seat 3 to move, the adjusting seat 3 is limited to linearly move on the accommodating cavity 5 through the second inner side surface 15 and / or the third inner side surface 16.

[0043] In this embodiment, the second inner side surface 15 and the third inner side surface 16 are linear limiting side surfaces.

[0044] A first positioning rotation assembly 17 is provided between the connecting arm 2 and the adjusting member 4, and the connecting arm 2 and the adjusting member 4 are cooperatively connected through the first positioning rotation assembly 17; a second positioning rotation assembly 18 is further provided between the adjusting seat 3 and the adjusting member 4, and the adjusting seat 3 and the adjusting member 4 are cooperatively connected through the second positioning rotation assembly 18; when the adjusting member 4 moves, it is positioned and rotated between the connecting arm 2 and the adjusting seat 3 through the first positioning rotation assembly 17 and / or the second positioning rotation assembly 18.

[0045] In this embodiment, the first positioning rotation assembly 17 includes a positioning groove provided on the connecting arm 1 and a positioning disk provided on the adjusting member 4. When the adjusting member 4 is installed, the positioning disk of the adjusting member 4 is embedded in the positioning groove of the connecting arm 1.

[0046] In this embodiment, the second positioning rotation assembly 18 includes an adjusting screw hole provided on the adjusting seat 3 and an eccentric screw shaft provided on the adjusting member 4. The eccentric screw shaft is provided with an external thread, and the adjusting screw hole is provided with an internal thread. When the adjusting member 4 is installed, the eccentric screw shaft of the adjusting member 4 is inserted into the adjusting screw hole of the adjusting seat 3.

[0047] The adjusting member 4 rotates in a stepped or stepless manner between the connecting arm 2 and the adjusting seat 3 through the first positioning rotation assembly 17 and / or the second positioning rotation assembly 18 to achieve stepped or stepless adjustment of the adjusting member 4.

[0048] In this embodiment, the adjusting member 4 is adjusted steplessly through the first positioning rotation assembly 17 and / or the second positioning rotation assembly 18.

[0049] Alternatively, the adjusting member 4 uses an eccentric rotating disk to achieve stepped adjustment.
