Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a hinge that can be adjusted at will. Background Art

[0002] Hinges are widely used, and are commonly used in doors, windows and cabinets. Existing hinges can basically only realize the function of opening and closing doors, and cannot fix the door in a certain position according to the need for the door opening angle. In some special places, the door needs to be fixed and opened to different angles. Therefore, there is a need for directional hinges that can be suspended at any angle in the market.

[0003] On May 2, 2023, the applicant disclosed "A directional hinge structure that can hover at any angle" with announcement number "CN218953075U", which solved the above-mentioned problem to a certain extent. It installs a first copper sheet and a second copper sheet on both sides of the head end of the first connecting arm, respectively, and fully utilizes the characteristics of the copper sheet to reduce the contact between the two connecting arms and other components, thereby reducing wear while ensuring friction. In actual use of this structure, the first copper sheet and the second copper sheet as gaskets will rotate with the connecting arm due to their rough surface at the beginning of use, causing friction and rotation between the gasket and the elastic sheet. After long-term use, the friction force will be unstable due to the unstable friction force, which will cause a large difference in friction from the previous period, thereby affecting the hinge's random stop function. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an adjustable hinge with arbitrary stop, including a first connecting arm, a second connecting arm, an elastic member, a first gasket, a second gasket and a pivot, wherein the pivot sequentially passes through the second connecting arm, the second gasket, the first connecting arm, the first gasket and the elastic member, and the first connecting arm and the second connecting arm are pre-positioned with each other by the elastic pre-tightening force of the elastic member, characterized in that: a first pivot hole is provided at the end of the first connecting arm, a second pivot hole is provided at the end of the second connecting arm, a third pivot hole is provided on the first gasket, and a third pivot hole is provided on the second gasket The fourth pivot hole, the pivot includes a stop portion, a threaded portion and a rotating portion arranged between the stop portion and the threaded portion, the stop portion is arranged on a side of the second connecting arm away from the second connecting arm, the cross-section of the rotating portion is a polygonal structure, and there is an arc transition structure between adjacent edges, the first pivot hole is a circular structure, which is adapted to the arc transition structure of the rotating portion, so that the first connecting arm is rotatably arranged on the rotating portion, the second pivot hole, the third pivot hole and the fourth pivot hole are adapted to the polygonal structure of the rotating portion, a nut is arranged on the threaded portion, and the nut abuts against the elastic member.

[0005] Furthermore, the elastic member is a spring piece group formed by stacking two disc-shaped spring pieces.

[0006] Furthermore, both end surfaces of the first gasket and the second gasket are grid structures, so that a plurality of chip collecting grooves are formed on the end surfaces of the first gasket and the second gasket.

[0007] Compared with the prior art, the beneficial effect of the utility model is: by setting the rotating part of the pivot to a polygonal structure, and the adjacent edges are arc transition structures, the second pivot hole of the second connecting arm, the third pivot hole of the first gasket and the fourth pivot hole of the second gasket are also set to polygonal structures that cooperate with the rotating part, so that when the hinge rotates, the second connecting arm, the first gasket and the second gasket are kept on one axis and do not rotate, and the first pivot hole of the first connecting arm is a circular structure, and is adapted to the arc transition structure in the polygonal structure of the rotating part. When the second connecting arm, the first gasket and the second gasket remain unchanged during the rotation of the hinge, the first connecting arm can rotate on the rotating part, so that the first gasket and the second gasket can only rotate by friction with the first connecting arm, thereby ensuring the consistency of friction force of the hinge during use.

[0016] It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0017] refer to Figures 1 to 4 A hinge with adjustable stop function comprises a first connecting arm 10, a second connecting arm 20, an elastic member 30, a first gasket 40, a second gasket 50 and a pivot 60, wherein the pivot 60 sequentially passes through the second connecting arm 20, the second gasket 50, the first connecting arm 10, the first gasket 40 and the elastic member 30, and the first connecting arm 10 and the second connecting arm 20 are pre-positioned with each other by the elastic preload force of the elastic member 30; wherein a first pivot hole 101 is provided at the end of the first connecting arm 10, a second pivot hole 201 is provided at the end of the second connecting arm 20, a third pivot hole 401 is provided on the first gasket 40, and a fourth pivot hole 501 is provided on the second gasket 50.

[0018] It should be understood that the pivot 60 includes a stop portion 601, a threaded portion 602 and a rotating portion 603 arranged between the stop portion 601 and the threaded portion 602. The stop portion 601 is arranged on the side of the second connecting arm 20 away from the second connecting arm 20. The cross-section of the rotating portion 603 is a polygonal structure, and there is an arc transition structure between adjacent edges. The first pivot hole 101 is a circular structure, which is adapted to the arc transition structure of the rotating portion 603, so that the first connecting arm 10 is rotatably arranged on the rotating portion 603. The second pivot hole 201 of the second connecting arm 20, the third pivot hole 401 of the first gasket 40 and the fourth pivot hole 501 of the second gasket 50 are also set to polygonal structures, and are consistent with the polygonal structure of the rotating portion 603. The two polygonal structures are adapted to achieve limiting.

[0019] During assembly, the rotating portion 603 of the pivot 60 passes through the second connecting arm 20, the second gasket 50, the first connecting arm 10, the first gasket 40 and the elastic member 30 in sequence, and then a nut 70 is screwed on the threaded portion 602 at the tail end so that the nut 70 abuts against the elastic member 30, thereby generating an elastic preload force between the first connecting arm 10 and the second connecting arm 20; in addition, the compressive elastic force of the elastic member 30 can be controlled by twisting the position of the nut 70, thereby adjusting the rotational tension between the first connecting arm 10 and the second connecting arm 20.

[0020] During use, when the hinge rotates, the second connecting arm 20, the first gasket 40, and the second gasket 50 remain on one axis and do not rotate, and the first pivot hole 101 of the first connecting arm 10 is a circular structure and is adapted to the arc transition structure in the polygonal structure of the rotating part 603. When the second connecting arm 20, the first gasket 40, and the second gasket 50 remain unchanged during the rotation of the hinge, the first connecting arm 10 can rotate on the rotating part 603, so that the first gasket 40 and the second gasket 50 can only rotate by friction with the first connecting arm 10, thereby ensuring the consistency of the friction force of the hinge during use.

[0021] Specifically, the elastic member 30 is an elastic member group formed by stacking two disc-shaped elastic members 301 ; in addition, the elastic member 30 can also be other elastic elements such as a spring.

[0022] Specifically, by setting a grid structure on the two end surfaces of the first gasket 40 and the second gasket 50, the friction between the first connecting arm 10 and the first gasket 40 and the second gasket 50 is increased, which can be applied to products with greater force requirements. The grid structure provides multiple grooves on the end surfaces of the first gasket 40 and the second gasket 50. The grooves can be used to collect metal chips generated by the friction and rotation between the first connecting arm 10 and the first gasket 40 and the second gasket 50, so that the grooves can be used as chip collecting grooves.

[0023] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the 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.
