What is a spring hinge?

The structure of spring hinge includes body, base, iron head, spring, adjusting screw, base screw, connecting piece, shrapnel, U-shaped nail and rivet, etc. The spring hinge is attached with adjusting screw, which can adjust the height and thickness of the plate up and down, left and right, One of its features is that it can match the opening angle of the cabinet door according to the space. Common spring hinges, pipe spring hinges and door spring hinges are common.

The spring hinge is mainly used for the connection of furniture door panels. It generally requires a thickness of 16~20 mm, and the material is galvanized iron and zinc alloy. The spring hinge is attached with adjustment screws, which can adjust the height and thickness of the panel up and down, left and right, one of its features is that it can be matched with the opening angle of the cabinet door according to the space. In addition to the general 90-degree angle, 127-degree, 144-degree, 165-degree, etc. have corresponding hinges to match, so that various cabinet doors have corresponding stretches.

We can see many different types of spring hinges around us. In short, spring hinges can be divided into the following categories. The first is the common ordinary spring hinges, which are mainly used in doors, windows, cabinets, etc. The second is the pipe spring hinge, which is mainly used for the connection between the door panels, and the thickness is generally between 16 mm and 20 mm. The third type is the door spring hinge, which is more beautiful in style and moderate in price. In addition, there are other spring hinges, such as glass and sub, flap hinges and other types.

Spring hinge installation tips

Minimum clearance refers to the minimum distance from the side of the door required to open the door. The minimum clearance is determined by the C distance, door thickness and spring hinge installation type. When the door edge is rounded, the minimum clearance is reduced accordingly. The required minimum clearance can be found in the correspondence table for each different hinge.

Minimum clearance for half-covered doors, when two doors share a side panel, the total clearance required shall be twice the minimum clearance so that both doors can be opened at the same time. C distance, C distance refers to the distance between the edge of the door and the edge of the hinge cup hole. The maximum C-dimension available for each hinge varies by hinge model. The larger the C distance, the smaller the minimum clearance. Door Coverage Distance, Door Coverage Distance refers to the distance the door covers the side panel. Gap refers to the distance from the outside of the door to the outside of the cabinet in the case of a full cover; in the case of a half cover, the distance between two doors; in the case of an inner door, the gap refers to the distance from the outside of the door to the inside of the cabinet side panel distance.
