Description

Self-adaptive hinge for folding screen

Technical Field

The invention relates to a self-adaptive hinge for a folding screen, which is used for folding a flexible screen, folding the flexible screen into two small screens, unfolding the small screens into a large screen, and having no crease in the middle of the large screen.

Background

The hinge of the known folding screen is the biggest disadvantage that it cannot be flat and crease-free when opened.

Disclosure of Invention

In order to overcome the defects of the folding screen hinge, the invention provides the folding screen self-adaptive hinge which can be deformed into a large screen and has no crease.

The technical scheme adopted by the invention for solving the technical problems is as follows: a self-adaptive hinge for a folding screen comprises an upper hinge, a middle long cylinder, a normally open spring and a lower hinge; the upper hinge is an n-shaped clip, the two legs of the clip are elastic sheets, salient points are arranged on the outer surfaces below the two elastic sheets, a fixed head top sheet is arranged at the head top of the clip, the arrangement direction of the head top sheet is parallel to the two elastic sheets, and a round hole is formed in the head top sheet; four hollowed-out long holes are formed in the periphery of the middle long cylinder, and are arranged in parallel in the vertical direction; the lower hinge is a U-shaped clip, two feet of the clip are upward elastic sheets, salient points are arranged on the outer surfaces above the two elastic sheets, a fixed bottom sheet is arranged at the bottom of the clip, the arrangement direction of the bottom sheet is vertical to the two elastic sheets, and a round hole is formed in the bottom sheet; the upper hinge is inserted from the upper part of the middle long tube, and the salient points of the two elastic sheets slide up and down on the corresponding long holes; the normally open spring is in a spring-open state in a normal state and can be placed into an inner space formed by combining the upper hinge and the middle-long barrel; the lower hinge is inserted from the lower part of the middle long cylinder, and the salient points of the two elastic sheets slide up and down in the corresponding long holes; in a normal state, the upper hinge and the lower hinge are in an open state, and pressure is applied to two ends of the upper hinge and the lower hinge to shorten the self-adaptive hinge of the folding screen.

The folding screen self-adaptive hinge is a component of the folding screen, and the folding screen consists of a flexible screen, an upper sheet body, a lower sheet body and the folding screen self-adaptive hinge; the upper sheet body and the lower sheet body are stacked mutually, one side edge of the stacked upper sheet body is aligned, the display surface of the flexible screen faces outwards, the flexible screen is attached to the upper surface of the upper sheet body from the other side of the upper sheet body to the alignment edge, the flexible screen continuously bypasses the side surfaces of the upper sheet body and the lower sheet body, then the flexible screen is attached to the lower surface of the lower sheet body from the alignment edge to the other side edge of the lower sheet body, and a flexible connecting part which is not attached is formed at the alignment side edge; meanwhile, the top sheet of the upper hinge is rotatably connected with the upper sheet body and the bottom sheet of the lower hinge is rotatably connected with the lower sheet body at the aligned edges of the two sheet bodies, the upper hinge and the lower hinge compress the normally open spring to shorten the self-adaptive hinge of the folding screen due to the limitation of the length of the flexible connecting part, and the self-adaptive hinge of the folding screen is embedded into the grooves of the upper sheet body and the lower sheet body; when the folding screen is opened into the flat state, upper and lower hinge opened because of normally opening the spring, and upper and lower lamellar body becomes horizontal arrangement, and the flexonics portion tiling of flexible screen is on folding screen self-adaptation hinge, and normally opening the spring pressurized little, and folding screen self-adaptation hinge becomes long, props the flexonics portion of flat flexible screen, makes the flexible screen open no crease completely.

The invention has the beneficial effect that the folding screen self-adaptive hinge is used, and the flat screen can be kept without folds when the folding screen is unfolded into a large screen.
