Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a universal rotating anti-dropping connecting piece for doors. Background Technique

[0002] A hinge, also known as a hinge, is a device that connects two objects and allows them to rotate relative to each other. In furniture and building structures such as doors, windows, cabinets, and boxes, hinges are widely used to connect door panels or covers to frames, enabling them to open and close.

[0003] In the existing technology, the connecting bolts of the hinge are exposed, which affects the aesthetics. In order to improve the aesthetics during the installation of the hinge, in view of this, we propose a universal rotating anti-dropping connecting piece for doors. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A universal rotating anti-dropping connecting piece for doors, comprising: a hinge sleeve and a mounting seat, the mounting seat is fixedly connected to the outer wall of the hinge sleeve, the number of the hinge sleeve and the mounting seat is two, and they are symmetrically arranged up and down, and a cushion is arranged between the two hinge sleeves and the mounting seats.

[0007] Preferably, a sleeve is inserted into the inner wall of the upper hinge sleeve, a sleeve is arranged on the inner wall of the sleeve, a first inner hexagon bolt is threadedly connected to the sleeve and the hinge sleeve, one end of the first inner hexagon bolt is in contact with the outer wall of the sleeve, and the other end of the first inner hexagon bolt is arranged in the mounting seat.

[0008] Preferably, a protective sleeve is sleeved on the outer wall of the sleeve, and the cushion is sleeved on the outer wall of the protective sleeve for anti-abrasion between the two hinge sleeves.

[0009] Preferably, steel balls are arranged inside the lower hinge sleeve, a second inner hexagon bolt is sleeved on the top of the sleeve, and the second inner hexagon bolt is threadedly connected to the steel balls.

[0010] Preferably, a third inner hexagon bolt is threadedly connected to the outer wall of the lower hinge sleeve and is used to limit the upward movement of the steel balls.

[0011] Preferably, covers are arranged at the ends of the two hinge sleeves away from the steel balls, and the covers are inserted into the inner walls of the hinge sleeves.

[0012] Compared with the existing technology, the beneficial effects of the utility model are:

[0013] When in use, the connecting piece is assembled and joined together by an assembly method. Bolts are not visible from the outside, and the bolts are hidden inside, improving the aesthetics of the entire connecting piece. At the same time, by setting a gasket between its two hinge sleeves, when the hinge is rotated, friction between the upper and lower hinges can be avoided, improving the smoothness of rotation.
