Abstract

The utility model discloses a two-dimensional hinge structure which mainly comprises a door frame half hinge, a door leaf half hinge, a hinge mandrel and a supporting piece. The door frame half hinge mounting plate is at least provided with a plurality of opening slots, two long waist round inclined surface mounting holes A and a group of or at least one threaded hole; the door leaf half hinge mounting plate is provided with a plurality of long waist round inclined surface mounting holes B and at least one round countersunk head mounting hole C which are parallel to the central line of the hinge central shaft. The long waist round inclined surface mounting hole B can adjust the position size parallel to the central line direction (namely up and down) of the hinge central shaft when the door leaf and the door frame are assembled. The door leaf half hinge penetrates through shaft holes of the door frame half hinge and the door leaf half hinge through a hinge mandrel, supporting pieces are arranged at inner hole ends of two rolling parts of the door leaf half hinge, and two ends of the hinge mandrel are riveted and fixed with two outer ends of the rolling part of the door leaf half hinge to form a hinge structure.

Description

Two-dimensional hinge structure

Technical Field

The utility model relates to a two-dimensional hinge structure, and belongs to hardware products.

Background

Hinges (or hinges) are one of the major components of door products and are typically fixedly mounted, or even assembled, to the door frame of a door. Particularly in the door products of the current industrial production, the assembly and the installation are very inconvenient, especially in the steel door products, because of the relation of sheet metal manufacturing precision, a three-dimensional adjusting hinge is very needed to adjust the assembly precision and the clearance requirement of the door leaf and the door frame, and the assembly of the products is convenient. In recent years, a hinge with a three-dimensional adjusting function is generally realized through a hinge fixing seat with a three-dimensional adjusting function. Therefore, it is necessary to develop a hinge structure which can adjust the assembling precision and clearance requirements of the door leaf and the door frame, has strong bearing capacity and has lower cost.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a hinge structure which has strong bearing capacity and low cost and can at least realize two-dimensional adjustment.

The following technical scheme is adopted by the utility model:

a two-dimensional hinge structure mainly comprises a door frame half hinge, a door leaf half hinge, a hinge mandrel and a supporting piece. The door frame half hinge is characterized in that at least a plurality of opening slots, two long waist round inclined surface mounting holes A and a group of or at least one threaded hole are formed in a hinge mounting plate; the door leaf half hinge penetrates through shaft holes of the door frame half hinge and the door leaf half hinge through a hinge mandrel, supporting pieces are arranged at inner hole ends of two rolling shaft holes of the door leaf half hinge, and two ends of the hinge mandrel are riveted or welded with two ends of the outer side of the rolling shaft hole of the door leaf half hinge to be fixed, so that a hinge structure is formed. Because the hinge mandrel is fixed into a whole by riveting or welding at the two ends of the outer side of the rolling shaft hole of the door leaf half hinge, the bearing capacity of the door leaf half hinge is greatly improved; the door frame half hinge is characterized in that a plurality of opening slots perpendicular to the axis of a hinge mandrel and two long waist round inclined surface mounting holes A are formed in a hinge mounting plate, and the hinge can adjust the position and the size of the door leaf and door frame assembly in the direction perpendicular to the axis of the hinge mandrel. After the relative positions of the door leaf and the door frame in the direction perpendicular to the axis of the hinge mandrel are adjusted, the door leaf and the door frame are locked and fixed at the threaded hole by using a screw, so that the position change is prevented.

The door leaf half hinge is characterized in that a hinge mounting plate is provided with a plurality of long waist round inclined surface mounting holes B parallel to the central line of a hinge central shaft and at least one round countersunk head mounting hole C. The long waist round inclined surface mounting hole B can adjust the position size parallel to the central line direction (namely up and down) of the hinge central shaft when the door leaf and the door frame are assembled, and after the position size of the door leaf and the door frame is adjusted, the door leaf is prevented from sagging for a long time by adopting screw drill matching fixation on the round countersunk head mounting hole C.

The two ends of the outer side of the rolling shaft hole of the door frame half hinge are provided with supporting pieces, and the supporting pieces can be T-shaped shaft sleeves or plane bearing structures or plane gaskets, and the plane bearing structures or the plane gaskets are preferred.

In summary, the mounting plate of the hinge is provided with the elongated opening mounting hole A and the elongated closing mounting hole B, and the door leaf and the door frame are convenient to install and debug due to the fact that at least two-dimensional adjustment is realized without three-dimensional function adjustment, and the product cost is low. In addition, the hinge mandrel is fixed into a whole with two winding shaft holes of the door leaf half hinge in a riveting or welding mode, so that the bearing capacity of the hinge is greatly increased, and the hinge is prevented from drooping under the stress.

fig. 2 is a front view illustrating a state that the hinge of the present utility model is opened 180 degrees.

The specific embodiment is as follows:

referring to fig. 1-2, a two-dimensional hinge structure mainly comprises a door frame half hinge (1), a door leaf half hinge (2), a hinge mandrel (3) and a supporting piece (4). The door frame half hinge (1) is characterized in that at least a plurality of opening slots (1-1), two long waist round inclined surface mounting holes A (1-2) and a group or at least one threaded hole (1-3) are formed in a hinge mounting plate; the door leaf half hinge (2) penetrates through shaft holes of the door frame half hinge (1) and the door leaf half hinge (2) through a hinge mandrel (3), supporting pieces (4) are arranged at inner hole ends of two rolling shaft holes of the door leaf half hinge (2), and two ends of the hinge mandrel (3) are riveted or welded and fixed with two ends of the outer side of the rolling shaft holes of the door leaf half hinge (2) to form a hinge structure. Because the hinge mandrel is fixed into a whole by riveting or welding at the two ends of the outer side of the rolling shaft hole of the door leaf half hinge, the bearing capacity of the door leaf half hinge is greatly improved; the door frame half hinge (1) is provided with a plurality of opening slots (1-1) perpendicular to the axis of the hinge mandrel (3) and two long waist round inclined surface mounting holes A (1-2), and the hinge can adjust the position and the size of the door leaf and the door frame assembly in the direction perpendicular to the axis of the hinge mandrel (3).
