Description

Double-shaft rotating arm hinge structure

(I) technical field

The invention relates to a double-shaft rotating arm hinge structure, belonging to hardware products.

(II) background of the invention

Hinges are an important component of door products. The hinge for the existing anti-theft door is characterized in that a gasket is added between a door frame half hinge and a door leaf half hinge in a general axial direction, a shaft sleeve is not radially designed, when the hinge bears load, friction between the door leaf half hinge and a gasket plane and between a core shaft and a door leaf half hinge shaft hole is severe, and the hinge takes a long time and can make a squeak noise. In addition, the market demand for high-grade security doors in recent years is increasing the adoption of concealed hinges. The concealed hinge is generally that the number of rotating arm hinges of a rotating shaft on a door frame is more, and the opening angle of a door leaf is only more than 90 degrees, so that the effective width of a door frame opening is influenced, and the carrying-in of large furniture is influenced. Therefore, it is increasingly important to develop and design a concealed hinge with a large opening angle, which is easy and flexible to open, has no noise, and can bear heavy weight.

Disclosure of the invention

Based on the above product defects and requirements, the technical problem to be solved by the present invention is to provide a dual-axis rotating arm hinge structure.

The following is the technical scheme adopted by the patent of the invention:

a double-shaft rotating arm hinge structure comprises a door frame half hinge, a rotating arm, a door leaf half hinge, a shaft 1, a shaft 2, a plane bearing 1, a plane bearing 2, a rotating arm limiting buckle plate, a guide riveting column, a buckle plate spring and a door leaf decorative sheet. The two ends of the shaft hole 1 and the shaft hole 2 of the rotating arm are provided with a plane bearing 1 and a plane bearing 2, the door frame is provided with a half hinge, the two ends of the shaft 1 are connected with the end 1 of the shaft hole of the rotating arm through the shaft 1, and the outer ends of the two rolling circle part shaft holes 3 of the two half hinges of the door frame are riveted or welded and fixed. The door leaf half hinge is connected with the end 2 of the shaft hole of the rotating arm through a shaft 2, and the two ends of the shaft 2 are riveted or welded with the outer ends of the two rolling round parts of the door leaf half hinge. Two rotating arm limiting buckle plates are arranged on the hinge leaf plate of the half door frame hinge, waist-shaped long holes are arranged on the two limiting buckle plates, and the hinge leaf plate is riveted to the half door frame hinge through a guide riveting column. The two limiting buckle plates enable the V-shaped buckle heads on the limiting buckle plates to be in place and automatically buckle into the V-shaped buckle grooves 1 or the V-shaped buckle grooves 2 on the rotating arm to clamp the rotating arm for positioning through the buckle plate springs.

When the rotating arm rotates to the V-shaped buckling groove 1 or the V-shaped buckling groove 2, the V-shaped buckling heads of the two limiting buckling plates are buckled in the V-shaped buckling groove 1 or the V-shaped buckling groove 2, so that the rotating arm is positioned and clamped. Be equipped with spacing dog on two edge rolling stabilizer blades of door leaf half-hinge, when door leaf half-hinge pivoted 2 extremely spacing, spacing dog supported shaft hole 2 edge rolling straight face and drives the V-arrangement discount that the rocking arm breaks away from spacing buckle, and the rocking arm rotates around axle 1 and makes the V-arrangement discount of spacing buckle change to V-arrangement buckle groove 2 from the V-arrangement buckle groove 1 of rocking arm to increased door leaf half-hinge and opened to the maximum angle position.

Two edges of the arc-shaped surface 2 of the section of the rotating arm close to the shaft hole 2 are respectively provided with an outward convex clamping point, and a mounting foot decorative sheet is designed on a mounting foot plate of the half hinge of the door leaf. The middle part of the upper edge of the door leaf is provided with an elastic turned edge corresponding to the convex clamping point on the rotating arm, when the half hinge of the door leaf rotates reversely, the elastic turned edge and the convex clamping point on the rotating arm are in place and abut against each other to drive the rotating arm to reset, and the V-shaped buckle head of the limiting buckle plate rotates from the V-shaped buckle groove 2 to the V-shaped buckle groove 1 to clamp and position the rotating arm.

Further, a flat bearing 1 and a flat bearing 2 are designed in the pivot shaft hole 1 and the shaft hole 2. The bearing is composed of a shaft sleeve 1, a gasket 1, a shaft sleeve 2 and a gasket 2 respectively, and plays a role of a plane bearing. Design axle sleeve 1 and axle sleeve 2, its axle hole interference fit with the half hinge of door frame and the half hinge of door leaf, the purpose is to avoid the axle hole and the axle 1 and the axle 2 within a definite time friction, has taken place the abnormal sound easily for a long time. The shaft sleeve 1 is fixed at two ends of the shaft hole 1 of the rotating arm, and the gasket 1 is arranged at the large-diameter end of the shaft sleeve 1 in a butting way with the end faces of the inner sides of the two rolling round part shaft holes 3 of the half hinge of the doorframe. The shaft sleeve 2 is fixed at two ends of the shaft hole 2 of the rotating arm, and the gasket 2 is arranged at the large-diameter end of the shaft sleeve 2 in a butting way with the inner side end faces of the two rolling round part shaft holes 4 of the half hinge of the door leaf. The gasket 1 and the gasket 2 are designed to prevent the shaft sleeve 2 and the shaft sleeve 1 from directly rubbing against the surfaces of the half hinge of the door leaf and the half hinge of the door frame, so that the large-diameter end surface of the shaft sleeve is protected from being easily abraded. The strength of the bearing surface is enhanced, and the hinge is opened flexibly and easily.

The invention has the advantages that: the hinge has the advantages of flexible and easy opening, strong bearing capacity and attractive appearance, and the hinge can be opened by 180 degrees or even a larger angle.
