Detailed Description

The utility model is further described below with reference to the accompanying drawings of the specification:

example 1:

as shown in fig. 1-13, the semicircular axis long chain for curved screen application provided by the embodiment includes multiple groups of first movable blocks 1 and second movable blocks 2 which are combined and connected, wherein the first movable blocks 1 are not less than two groups, and are sequentially combined end to form a long chain structure, and because the first movable blocks 1 are in an end to end structure, at least two groups are required to form a complete connection unit, and the second movable blocks 2 are linked with the first movable blocks 1; the first movable blocks 1 comprise semicircular arc grooves 11 and semicircular arc sliding blocks 12, and two adjacent groups of first movable blocks 1 are in rotary connection through sliding fit of the semicircular arc grooves 11 and the semicircular arc sliding blocks 12 which are connected front and back; the first movable block 1 is provided with a sliding column 13, the second movable block 2 is provided with a curved slot 14, and the sliding column 13 slides in the curved slot 14 to realize the rotary connection of the first movable block 1 and the second movable block 2.

The clamping groove 15 is formed in the first movable block 1, which is close to the inner side of the semicircular groove 11, and the elastic sheet 3 for providing torsion is arranged in the clamping groove 15. When the semicircular arc block 12 slides in the semicircular arc groove 11, the semicircular arc block 12 can be contacted with the elastic sheet 3 to form extrusion, the semicircular arc block 12 is stressed to generate resistance through the elastic force of the elastic sheet 3, and the upper end face of the first movable block 1 and the upper end face of the second movable block 2 are provided with a first connecting plate 4 for realizing running fit and connecting positioning. The lower end surfaces of the first movable block 1 and the second movable block 2 are provided with a second connecting plate 5 for realizing connection and positioning.

In this embodiment, the first movable block structure forming the end face of the long chain structure is not required to be connected in front of the first movable block structure, so that only a semicircular arc groove directly connected with the first movable block structure is required to be designed in structure, and other structures are not required.

The embodiment designs casing 6, casing 6 one end is equipped with three sets of connecting blocks 7, connecting block 7 links to each other with long-chain 9 combination, covers curved surface screen 8 on first connecting plate 4. The curved screen 8 can realize the function of bending inwards and outwards or outwards by taking the shell 6 as a plane standard through the long chain 9. In addition, when different bending angles are formed in the bending process, the bending points between the linkage of each movable block can achieve equal length of chord arcs, namely the length between the radian of the change of the bending angle and the outer tangent point of the bending radius is kept unchanged, and the device has the advantages that no damage is caused to the screen due to secondary folding no matter the screen is outwards bent or inwards bent, and the device can play a good role in protecting the screen.
