Description

Conjoined hinge corner connector Technical Field The utility model relates to the technical field of box fittings, in particular to a conjoined hinge corner connector. Background In the prior art, although the conjoined hinge angle code exists, the following defects exist: Most hinge caps are vertically aligned, so that the axle center is stressed unevenly and is easy to wear after long-term use; the contact area of the leaf and the box body is limited, the bolt hole distribution is unreasonable, and local stress concentration is easy to cause; The lack of a targeted reinforcement design makes it difficult to meet the use requirements under high loads or severe environments. Disclosure of utility model The utility model aims to provide an conjoined hinge corner connector for solving the problems in the background technology. In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The conjoined hinge corner connector comprises an upper leaf and a lower leaf, wherein the upper leaf and the lower leaf are rotationally connected through a hinge axis, the upper leaf is connected with an upper connecting plate, the lower leaf is connected with a lower connecting plate, and mounting holes are formed in the upper leaf, the lower leaf, the upper connecting plate and the lower connecting plate. Preferably, the upper hinge cap is arranged on the upper hinge, the lower hinge cap is arranged on the lower hinge, the upper hinge cap and the lower hinge cap are arranged in a left-right staggered mode, and the axis of the hinge penetrates through the inside of the upper hinge cap and the inside of the lower hinge cap. Preferably, the upper leaf and the lower leaf are both provided with extension plates, and the end parts of the extension plates are provided with oblique cuts. Preferably, right-angle reinforcing strips are arranged at the joint of the upper leaf and the upper connecting plate and the joint of the lower leaf and the lower connecting plate. Preferably, the mounting holes are multiple and uniformly distributed on the upper page, the lower page, the upper connecting plate and the lower connecting plate. The utility model has at least the following beneficial effects: The upper leaf and the lower leaf are connected through the hinge axle center in a rotating way, so that the flexible opening and closing functions of the box cover and the box body are realized, the hinge structure ensures smooth rotation, friction loss is reduced, and the service life is prolonged. Upper and lower connection plates and mounting holes: the upper connecting plate and the upper leaf are fixed with the bottom of the box cover through the mounting holes, and the lower connecting plate and the lower leaf are fixed with the top of the box body through the mounting holes, so as to provide a stable connecting foundation. The plurality of mounting holes are evenly distributed, so that stress is dispersed, looseness caused by overlarge single-point stress is avoided, and connection reliability is enhanced. The upper hinge cap and the lower hinge cap are arranged in a left-right staggered way: the staggered structure enables the stress of the hinge axle center to be more uniform, and the bearing capacity and stability of the hinge are improved. The hinge axle center is protected from external collision and dust invasion, and the service life of the hinge is prolonged. Extension plate and oblique cut: The extension plate increases the contact area between the leaf and the case cover/case body, and improves the stability and anti-torsion capability of connection. The inclined notch design avoids the interference of the extension plate and the edge of the box body in the opening and closing process of the box cover, and ensures smooth movement. Right angle reinforcing strip: the joint of the reinforcing sheet and the connecting plate enhances the structural strength and prevents the joint from deforming or breaking caused by frequent opening and closing. The rigidity and the shock resistance of the whole corner brace are improved, and the corner brace is suitable for heavy or frequently used boxes.
