Description

Hinge arbitrary angle positioning mechanism

Technical Field

The utility model relates to the technical field of hardware, in particular to a hinge positioning mechanism with any angle.

Background

Hinges, also known as hinges, are mechanical devices used to connect two solids and allow relative rotation between them. The hinge is constructed of a movable component or is constructed of a foldable material. The hinges are mainly arranged on doors and windows, and more hinges are arranged on cabinets and are mainly classified into stainless steel hinges and iron hinges according to materials; hydraulic hinge has appeared again for letting people obtain better enjoyment, and its characteristics are brought the buffer function when the cabinet door is closed, and furthest has reduced the cabinet door and has closed the noise that the cabinet body collision sent.

The hinge is an accessory necessary for the use of doors and windows, the common hinge does not play a role in positioning the opening of the doors and windows, if the common hinge is blown by wind, the doors and the window sashes can rotate, the door and the window sashes can be freely opened and closed automatically, a loud sound is emitted, especially, the glass doors even cause the damage of the doors and the windows or the occurrence of safety accidents and the like. The traditional door and window are positioned by adopting hooks or bolts, so that the defects of inconvenient use exist, various hooks are easy to damage and cannot be used in a short time, especially the hooks are easy to unhook when wind blows, and the opening angle of the door and the window cannot be adjusted. In order to ensure that the door does not collide with the wall after being opened or prevent the door from being blown by wind to cause closing, a door stopper is generally arranged between the door and the wall in the prior art, so that the door is limited and positioned. Hinge and door-inhale the product of two kinds of single different functions, all need supporting independent installation to accomplish when using, waste time and hard like this, and with high costs, the unable door-inhale of installing of occasion wall body a bit, the door body can't reach the location spacing.

Chinese patent No. CN 206429097U discloses a positioning hinge with positioning function, but the positioning hinge can only limit the included angle between two hinge plates to 60 degrees, 90 degrees, and 120 degrees, and the limited angle range is small, which cannot meet the requirement of multi-position stop. In order to stop the door at a specific position, the number of additional parts and the installation workload can be reduced. The utility model discloses a hinge positioning mechanism with any angle, which realizes the opening and closing of a door and a window at any angle and is convenient to install.
