Background technique

A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. The hinge may be composed of movable components or foldable materials. The hinge is mainly installed on doors and windows. The hinges are more installed on the cabinets. According to the classification of materials, they are mainly divided into stainless steel hinges and iron hinges; in order to allow people to enjoy better, hydraulic hinges (also known as damping hinges) have appeared. It has a buffer function, which minimizes the noise caused by the collision with the cabinet when the cabinet door is closed. At present, the structure design of the cabinet door hinge is unreasonable, and the service life is low, especially the door opening force and door opening angle cannot be adjusted, and the operation is inconvenient.

Pivotally connected, the curved pull piece is pivotally connected to the hinge housing through the second pin, one end of the curved pull piece is hinged to the end of the hinge push rod, and the other end of the curved pull piece is attached to the roller.

Wherein the lower end of the fixed hook is provided with a card slot, and the fixed hook is fixedly connected to the fixed surface through the card slot. The curved pull piece is provided with a cam curved surface matched with the roller, and the curved pull piece is attached to the roller through the cam curved surface.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model has a simple structure, not only the cabinet door can be opened to a larger angle, but also occupies a relatively small space, and the door opening force and the door opening angle can be adjusted by adjusting the size of the spring force and the curved surface shape of the curved pull piece, and the operation is convenient.

detailed description

Below in conjunction with accompanying drawing and embodiment of description, the specific embodiment of the present utility model is described in further detail:

Referring to a pull-down cabinet door hinge shown in Figure 1, it includes a cabinet door 1 hinged to a fixed surface 8, a hinge shell 2, a hinge push rod 3, a spring 4, a curved pull piece 5, a fixed hook 6, a roller 7, a second A pin 9 and a second pin 10; the hinge jack 3 is provided with a long slot, and the hinge jack 3 is connected to the hinge shell 2 through a limit pin passing through the slot, and the hinge jack 3 can move along the direction of the slot. Move, the spring 4 is sleeved on the hinge push rod 3, one end of the spring 4 is against the limit pin, and the other end of the spring 4 is against the end of the hinge push rod 3.

The hinge housing 2 is fixedly connected to the cabinet door 1, and the fixed hook 6 is fixedly connected to the fixed surface 8. Specifically, the lower end of the fixed hook 6 is provided with a card slot 61, and the fixed hook 6 is fixedly connected to the fixed surface 8 through the card slot 61. .

The roller 7 is freely rotatably connected to the fixed hook 6, the hinge housing 2 is pivotally connected with the fixed hook 6 through the first pin 9, and the hinge housing 2 can rotate around the first pin 9; the curved pull piece 5 passes through the second The pin 10 is pivotally connected to the hinge housing 2 , and the curved pull piece 5 can rotate around the second pin 10 .

One end of the curved pull piece 5 is hinged to the end of the hinge push rod 3 , and the other end of the curved pull piece 5 is attached to the roller 7 . Specifically, the curved pull piece 5 is provided with a cam curve surface matched with the roller 7, and the curve pull piece 5 is attached to the roller 7 through the cam curve surface.

The working process of the pull-down cabinet door hinge is as follows: the spring 4 always pushes the hinge push rod 3 forward through the elastic force, and the hinge push rod 3 is connected with the curved pull piece 5, and the curved pull piece 5 is moved by the force of the hinge push rod 3 Its second pin 10 rotates as the center, and the rotational force of the curved pull piece 5 makes the cam curve surface above it close to the hinge roller 7, so that when the door is opened, the hinge housing 2 is connected with the first pin of the fixed hook 6 9 is the rotation of the center of the circle. When it rotates, it pulls the curved pull piece 5. The curved pull piece 5 is always close to the roller 7 to make a curved motion due to the thrust of the hinge push rod 3. The curved motion determines the size of the door opening force and the door opening. angle.

The above is only a preferred embodiment of the present utility model, and does not make any limitation to the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model, All still belong to within the scope of the technical solution of the utility model.
