[0001] The utility model relates to the technical field of hinges for household cabinets, in particular to a hinge with a rotating shaft and a positioning function. Background Art

[0002] In the existing hinge opening state, a stop structure is generally provided on the hinge to limit the opening angle of the hinge. For example, Chinese Patent No. ZL201920961604.0 discloses a hinge, including a movable leaf plate, a fixed leaf plate and a hinge shaft. The movable leaf plate is provided with a shaft sleeve, the fixed leaf plate is provided with a shaft seat, the hinge shaft is fixed to the shaft seat, the shaft sleeve is sleeved on the hinge shaft and can rotate relative to the hinge shaft, a limit protrusion is provided in the shaft sleeve that rotates with the shaft sleeve, and an opening stop protrusion corresponding to the rotation track of the limit protrusion is provided on the shaft seat. The limit protrusion rotates a certain angle along the opening direction of the movable leaf plate relative to the hinge shaft with the shaft sleeve and is blocked by the opening stop protrusion. It has the function of limiting the opening position of the movable leaf plate to prevent the movable leaf plate from bumping against the fixed leaf plate when it is opened. This structure of blocking and limiting the opening angle of the hinge cannot position the hinge at the corresponding opening position, and the movable leaf plate of the hinge can still rotate at will. Utility Model Content

[0003] The purpose of the utility model is to provide a hinge with a positioning function using a rotating shaft. By providing a first action position on the rotating shaft, when the hinge is opened, the elastic mechanism elastically acts on the first action position of the rotating shaft, the hinge maintains the corresponding position angle of opening, and the hinge cannot be rotated and closed at will. In addition, the elastic mechanism releases elastic force and acts on the first action position of the rotating shaft when the hinge is opened, thereby realizing elastic opening of the hinge.

[0004] A hinge with a rotating shaft and a positioning function designed for this purpose includes a door panel hinge cup and a side panel hinge cup. A rotating shaft is provided on the rotating hinge between the door panel hinge cup and the side panel hinge cup. The door panel hinge cup and the side panel hinge cup are rotatably connected via the rotating shaft. An elastic mechanism that elastically acts on the rotating shaft is provided on the side panel hinge cup. The rotating shaft is provided with a first action position. When the door panel hinge cup is closed on the side panel hinge cup, the elastic mechanism is in a compressed state, and the door panel hinge cup rotates and opens relative to the side panel hinge cup. When the rotating shaft rotates with the door panel hinge cup to the corresponding position, the elastic mechanism releases the elastic force and acts on the first action position, so as to realize the positioning and opening of the door panel hinge cup on the side On the plate hinge cup, by providing a first action position on the rotating shaft, when the hinge is opened, the elastic mechanism elastically acts on the first action position of the rotating shaft, the hinge maintains the corresponding position angle of opening, and the hinge cannot be rotated and closed at will. In addition, the elastic mechanism releases the elastic force and acts on the rotating shaft when the hinge is opened, and the rotating shaft rotates under the force, gradually driving the door panel hinge cup to rotate, thereby realizing the elastic opening of the hinge. When the rotating shaft rotates to the first action position and acts on the elastic mechanism, the door panel hinge cup stops rotating and is positioned and opened on the side panel hinge cup. After the door panel hinge cup is positioned and opened, it needs to continue to be under the action of force to continue to open, so that the hinge can be fully opened.

[0005] There is also a second action position and an arc-shaped notch on the rotating shaft. The arc-shaped notch is set between the first action position and the second action position. The first action position and the second action position are transitionally connected through the arc-shaped notch. The door panel hinge cup rotates and closes relative to the side panel hinge cup. The rotating shaft follows the door panel hinge cup to rotate to the corresponding position and squeezes the elastic mechanism. The elastic mechanism acts on the notch. The rotating shaft drives the door panel hinge cup to close on the side panel hinge cup under the elastic force of the elastic mechanism to realize automatic closing of the hinge. The elastic mechanism acts on the second action position when the hinge is in the closed state. The arc-shaped notch and the second action position form a cam structure on the shaft. When the hinge rotates to close the corresponding position, the elastic mechanism acts on the rotating shaft along the arc surface of the second action position. The rotating shaft is subjected to force, and the hinge begins to close automatically.

[0006] The rotating shaft is provided with an arc surface which is arranged adjacent to the first acting position. The first acting position is a planar structure. When the door panel hinge cup is positioned and opened on the side panel hinge cup and the door panel hinge cup continues to be subjected to force to open on the side panel hinge cup, the first acting position of the rotating shaft passes over the elastic mechanism, and the elastic mechanism acts on the arc surface of the rotating shaft. The elastic mechanism elastically drives the rotating shaft to rotate and open the door panel hinge cup. The arc surface forms a rolling contact with the elastic mechanism to realize the elastic opening of the hinge.

[0007] The rotating shaft forms rolling contact with the elastic mechanism through the arc surface, which effectively reduces the friction contact between the rotating shaft and the elastic mechanism, making the hinge open and close smoothly.

[0008] The door panel hinge cup is provided with a connecting piece that cooperates with the rotating shaft, the connecting piece is provided with a bearing, the bearing is provided with a flat shaft hole that cooperates with the flat shaft portion, the flat shaft portion is inserted into the flat shaft hole to realize the connection between the door panel hinge cup and the rotating shaft, and the rotating shaft and the door panel hinge cup are rotated synchronously through the flat shaft portion.

[0009] The door panel hinge cup is provided with a connecting piece connected to the rotating shaft, the connecting piece is provided with a flat shaft hole matched with the flat shaft part, and the flat shaft part is inserted into the flat shaft hole to realize the connection between the door panel hinge cup and the rotating shaft.

[0010] An axial cavity is arranged on the side panel hinge cup, a rotating shaft is inserted into the axial cavity, and both ends of the rotating shaft extend out of the axial cavity and are rotatably connected with the door panel hinge cup, and the rotating shaft is positioned and rotated on the axial cavity.

[0011] The elastic mechanism comprises a compression spring and an acting member. The acting member is arranged on the end of the compression spring. The compression spring acts elastically on the rotating shaft through the acting member. The material of the acting member is plastic.

[0012] The side plate hinge cup is provided with an installation cavity for limiting the installation of an elastic mechanism, and the elastic mechanism moves in the installation cavity in a limited manner during the opening and closing process of the hinge.

[0013] A buffer is provided on the door panel hinge cup, and the door panel hinge cup is rotated and closed relative to the side panel hinge cup. When the door panel hinge cup is rotated and closed to the corresponding position, one end of the buffer acts on the side panel hinge cup to achieve buffered closing of the hinge, and the buffer is hidden between the door panel hinge cup and the side panel hinge cup when the hinge is closed.

[0014] An assembly cavity for installing a buffer is provided on the door panel hinge cup.

[0015] The utility model has the following beneficial effects:

[0016] By providing a first action position on the rotating shaft, when the hinge is opened, the elastic mechanism elastically acts on the first action position of the rotating shaft, the hinge maintains the corresponding position angle of opening, and the hinge cannot be rotated and closed at will.
