Description

Technical Field

[0001] This utility model relates to the technical field of hinge openers, specifically to a new type of hinge opener that is safe, environmentally friendly, and convenient to use. Background Technology

[0002] A hinge, also known as a hinge opener, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. While hinges are mainly installed on doors and windows, they are more commonly installed on cabinets. Based on material, they are mainly divided into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is a buffering function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body.

[0003] There are various types of existing hinge openers, including conventional hinges and hydraulic hinges. Conventional hinges do not have a self-locking function and are easy to close when open, which can cause the load to impact the human body, resulting in low safety. While hydraulic hinges have damping self-locking performance, their internal structure is complex, making them inconvenient to maintain and costly. Therefore, there is an urgent need for a new type of hinge opener that is safe, environmentally friendly, and convenient to use to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide a new type of hinge opener that is safe, environmentally friendly and convenient to use, in light of the current state of the technology.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a novel hinge opener / closer that is safe, environmentally friendly, and convenient to use. It includes symmetrically arranged mounting bases, on which is an L-shaped first hinge rod. A connecting shaft is installed at one end of the first hinge rod. Two sets of limiting rings are symmetrically fixed on one side wall of the first hinge rod. A limiting box is fixed on one side wall of the mounting base. Multiple sets of limiting grooves are circumferentially distributed within both the limiting rings and the limiting box. A limiting block matching the specifications of the limiting grooves is fixed to both the connecting shaft and one end of the first hinge rod. Two sets of second hinge rods are symmetrically installed on the connecting shaft, and a connecting base is fixed to one end of each second hinge rod.

[0006] Furthermore, the first hinge rod is hinged to the mounting base, and a protruding shaft is reserved at one end of the first hinge rod.

[0007] Furthermore, the connecting shaft is rotatably mounted on one end of the first hinge rod, one end of the second hinge rod is connected to the connecting shaft, and the connecting seat is fixed at the bottom end of the second hinge rod.

[0008] Furthermore, mounting holes are provided at the four corners of the upper end of both the mounting base and the connecting base.

[0009] Furthermore, the limiting ring is welded to one side wall of the first hinge rod, and the connecting shaft is rotatably connected to the limiting ring.

[0010] Furthermore, the limiting box is fixed to one side wall of the mounting base by screws, and the limiting grooves are all formed inside the limiting ring and the limiting box, and the limiting grooves are arc-shaped structures.

[0011] Furthermore, the limiting block is fixed on the connecting shaft and the convex shaft at one end of the first hinge rod, and the specifications of the limiting block match those of the limiting groove.

[0012] Furthermore, a connecting plate is welded between the first hinge rods, and an angle iron is also welded between the connecting plate and the first hinge rod.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention employs a limiting and locking mechanism consisting of a limiting box, a limiting ring, a limiting groove, and a limiting block. During the normal opening and closing of the hinge opener, the limiting block follows the first hinge rod and the connecting shaft, sequentially positioning itself within the limiting groove. When external force is lost, the limiting block and the limiting groove limit the opening angle of the hinge opener, achieving self-locking and thus improving its safety during use. Furthermore, this structure is simple, easy to maintain, ensures its portable switching performance, and has high usability. Attached Figure Description
