Description

Technical Field

[0001] The utility model belongs to the technical field of hinges and relates to a single-side slotted hinge. Background Art

[0002] Door frame hinges, also often called door hinges, are metal parts located between the door leaf and the door frame. Their main function is to hang the door leaf and fix it to the door frame to ensure that the door leaf can be opened and closed smoothly. Single-sided slotting of hinges refers to slotting on one side of the door or window, and installing the hinge in it, so that the door or window fits tightly against the wall.

[0003] In order to increase the installation strength, traditional single-sided slotted hinges are equipped with relatively thick connecting plates, which makes it difficult to store the connecting plates. Therefore, the mounting plates on both sides of the hinge need to be provided with mounting cavities for storing the hinges, or the mounting shells need to be widened to accommodate more connecting plates, which limits the application range of the hinges. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and provide a high-strength adjustable 180° flat opening single-side slotted hinge.

[0005] The purpose of the present utility model can be achieved through the following technical solutions: a 180° three-dimensional adjustable single-sided slotted hinge, characterized in that it includes a mounting shell, a mounting seat is provided on the mounting shell, a hinge plate unit is provided on the mounting seat, a plurality of pivot holes for mounting the hinge plate unit are provided on the mounting seat, and the plurality of pivot holes are arranged on the same vertical line, the hinge plate unit is provided with a connecting plate 1 and an L-shaped connecting plate 2, the connecting plate 2 is provided with a mounting groove, the connecting plate 1 is provided at the bottom of the connecting plate 2, and the top of the connecting plate 1 is in conflict with the connecting plate 2, one end of the connecting plate is provided with an L-shaped plate with a hinged connection, the L-shaped plate is placed in the mounting groove, the turning points of the connecting plate 2 are all through holes connected to each other, an auxiliary plate for intersecting connection is provided at the two ends of the connecting plate, and a mounting plate is provided at the end of the hinge plate unit.

[0006] In the above-mentioned 180° three-dimensional adjustable single-sided slotted hinge, symmetrical limiting bosses are provided on the mounting shell, and the limiting bosses are provided with height adjustment bolts and locking mounting holes, connecting ears are provided on both sides of the mounting seat, and the connecting ears are provided with adjustment guide grooves and height adjustment holes, and the adjustment guide grooves are provided with locking bolts.

[0007] In the above-mentioned 180° three-dimensionally adjustable single-side slotted hinge, mounting cavities are provided at both ends of the mounting plate, and adjustment mounting holes and locking mounting holes are provided in the mounting cavities.

[0008] In the above-mentioned 180° three-dimensionally adjustable single-side slotted hinge, the mounting cavity is provided with an engaging cover plate.

[0009] In the above-mentioned 180° three-dimensionally adjustable single-sided slotted hinge, a plurality of snap-in holes are provided at both ends of the mounting shell and in the mounting cavity, a decorative plate is provided on the mounting shell, and fixing holes are provided at both ends of the mounting shell.

[0010] In the above-mentioned 180° three-dimensionally adjustable single-side slotted hinge, both the decorative plate and the engaging cover plate are provided with snap-fitting columns.

[0011] In the above-mentioned 180° three-dimensional adjustable single-sided slotted hinge, the connecting plate 1, connecting plate 2, L-shaped plate, and auxiliary plate are all provided with hinge holes, and the connecting plate 1, connecting plate 2, L-shaped plate, and auxiliary plate are all provided with reinforcement parts arranged concentrically with the hinge holes.

[0012] In the above-mentioned 180° three-dimensionally adjustable single-side slotted hinge, the mounting plate is provided with an engaging cavity for the reinforcing portion to be engaged.

[0013] In the above-mentioned 180° three-dimensionally adjustable single-side slotted hinge, the mounting seat is provided with a receiving cavity for receiving the hinge plate assembly.

[0014] Compared with the existing technology, this 180° three-dimensional adjustable single-sided slotted hinge achieves 180° opening and closing by setting a hinge plate unit. Multiple connecting plates are hingedly connected to each other and the hinge is positioned more stably when opened through multiple interference limits. The hinge hinge is strengthened by setting a reinforcement part that is connected to the axis of the hinge hole, so that the hinge can bear a larger load. The height adjustment bolt and the locking bolt cooperate with each other to increase the adjustability of the hinge and the applicable range of the hinge. The short foldable storage length of the L-shaped plate can reduce the width of the installation shell and the size of the installation cavity required for installation, so that the hinge has a wider range of application. At the same time, the smaller installation cavity can increase the structural strength of the door panel or door frame. BRIEF DESCRIPTION OF THE DRAWINGS
