Specifications are: &26, &35. There are detachable directional hinges and non-detachable non-directional hinges. For example, the 303 series of Longsheng hinges are detachable directional hinges, while the 204 series are non-detachable spring hinges. They can be divided in shape: full cover (or straight arm, straight curved) half cover (or curved arm, middle The inner side (or big bend, big bend) hinges are equipped with adjusting screws, which can adjust the height and thickness of the board up and down, left and right. The distance between the two screw fixing holes on the side of the hole is generally 32mm, and the distance between the diameter side and the two sides of the board is 4mm (Drawing pictures). In addition, spring hinges have a variety of special specifications, such as: inner 45 degree angle hinge, outer 135 degree angle hinge, opening 175 degree angle hinge.
The difference between the three hinges of right angle (straight arm), half curve (half curve) and big curve (big curve):
The right-angled hinge allows the door to completely cover the side panel;
Half-curved hinges allow the door panel to cover part of the side panel;
The large curved hinge can make the door panel and the side panel parallel;

From the perspective of consumption, more copper bearing hinges are used, because they are beautiful in style, beautiful, affordable, and equipped with screws.

5. Heavy hinge
Due to the particularity of the installation position, the requirements for the hinge are also very large. The general size is above 150MM, the bearing capacity is large, and the shape and structure conform to the special structure of the cabinet door.
