DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, the first embodiment of the utility model is a curved lock 10, comprising a curved lock tongue 11, a curved lock sleeve 12 and a locking mechanism, wherein the curved lock tongue 11 is slidably inserted in the curved lock sleeve 12, and the locking mechanism locks or loosens the curved lock tongue 11 and the curved lock sleeve 12. The curvature of the curved lock 10 is controlled by controlling the position of the curved lock tongue 11 in the curved lock sleeve 12.

[0022] The locking mechanism includes an active cavity 111 , a graduation sliding hole 121 and a graduation stopper 13 .

[0023] The movable cavity 111 is disposed in the arc-shaped lock tongue 11, and the opening of the movable cavity 111 faces upward. The indexing slide hole 121 is disposed on the upper cover plate of the arc-shaped lock sleeve 12, and a plurality of upper limiting teeth 122 are distributed on the lower edge surface of the indexing slide hole 121; the upper end of the indexing limiter 13 is provided with a lower limiting tooth 131, and is floatingly disposed in the movable cavity 111.

[0024] When the indexing stopper 13 floats to the upper part of the active cavity 111, the lower limit teeth 131 engage with the upper limit teeth 122 to lock the arc-shaped lock tongue 11 and the arc-shaped lock sleeve 12. When the indexing stopper 13 floats to the lower part of the active cavity 111, the lower limit teeth 131 separate from the upper limit teeth 122 to loosen the arc-shaped lock tongue 11 and the arc-shaped lock sleeve 12. The locking and loosening of the arc-shaped lock tongue 11 and the arc-shaped lock sleeve 12 are controlled by controlling the position of the indexing stopper 13 in the active cavity 111.

[0025] A guide slot 112 is provided on the inner wall side of the movable cavity 111, and a guide protrusion 132 is provided on the side of the indexing stopper 13; the guide protrusion 132 is embedded in the guide slot 112 and moves along the guide slot 112. The cooperation between the guide slot 112 and the guide protrusion 132 can make the floating of the indexing stopper 13 more stable.

[0026] The locking mechanism further includes a return spring 14, which is disposed in the movable cavity 111; one end of the return spring 14 presses the bottom of the indexing stopper 13, and the other end presses the bottom surface of the inner wall of the movable cavity 111. The return spring 14 can keep pressing the indexing stopper 13 upward, so that the lower limit tooth 131 and the upper limit tooth 122 are kept in meshing and positioning, so that the arc-shaped lock tongue 11 and the arc-shaped lock sleeve 12 are kept in a locked state.

[0027] The indexing stopper 13 is provided with a connecting column 15, and the connecting column 15 is movably inserted into the indexing slide hole 121; the upper end of the connecting column 15 is connected to a button 16, and the lower end is connected to the upper end of the indexing stopper 13. When the staff adjusts the arc, they press the button 16 to overcome the elastic force of the reset spring 14, so that the lower limit tooth 131 is separated from the upper limit tooth 122, the arc-shaped lock tongue 11 and the arc-shaped lock sleeve 12 are loosened, and the arc-shaped lock tongue 11 can slide, thereby adjusting the arc.

[0028] like Figure 4 As shown, the second embodiment provided by the utility model is a flexible LED display module, including a power box assembly 20, a left frame assembly 30, a right frame assembly 40, a flexible screen 50 and the arc lock 10 as described in the first embodiment, the power box assembly 20 is installed in the middle of the back side of the flexible screen 50, the left frame assembly 30 and the right frame assembly 40 are respectively installed on the left edge and the right edge of the back side of the flexible screen 50, the left frame assembly 30 and the power box assembly 20 are connected by an arc lock 10, and the right frame assembly 40 and the power box assembly 20 are connected by another arc lock 10.
