Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.

The utility model provides a prevent that it includes to cross to open from spacing door hinge: as shown in fig. 1, the fixed blade 100 and the rotating blade 200 are hinged to each other, the fixed blade 100 is provided with a limiting block 300, a vibration reduction plate 400 is attached to one side of the limiting block 300 close to the rotating blade 200, specifically, the vibration reduction plate 400 includes a connecting surface 410 and a vibration reduction surface 420 which are opposite, the connecting surface 410 is connected to the limiting block 300, the vibration reduction surface 420 can contact with the root of the rotating blade 200, and the shape of the vibration reduction surface 420 is matched with the root of the rotating blade 200. Preferably, the vibration damping sheet 400 is vulcanized rubber.

It can be understood that the rotating blade 200 rotates by a large maximum opening limit from a closed state, the rotating angle range is 90-96 degrees, in order to limit the maximum rotating angle of the rotating blade 200 and prevent the problem of over-opening of the rotating blade 200, a limiting block 300 is mounted on the fixed blade 100, and the limiting block 300 can limit the opening degree of the rotating blade 200 when the rotating blade 200 rotates to open; when the rotating sheet 200 is opened to the maximum angle, the rotating sheet 200 collides with the limiting block 300, a vibration reduction sheet 400 is attached to one side, close to the rotating sheet 200, of the limiting block 300, and the vibration reduction sheet 400 can prevent rigid impact from occurring between the rotating sheet 200 and the limiting block 300, so that damage to the rotating sheet 200 is avoided.
