Device for quick splicing of a display screen

摘要

A device for quick splicing of a display screen is provided. The device includes a left assembly and a right assembly. The left assembly includes a rotation fixing seat, a rotation angle seat, a rotation locking mechanism, and a step angle-adjusting and clamping mechanism. The rotation angle seat can lock with the right assembly, and is rotatably connected to the rotation fixing seat. The rotation locking mechanism is disposed between the rotation fixing seat and the rotation angle seat. When the rotation locking mechanism is unlocked, the rotation angle seat can rotate relative to the rotation fixing seat; and when the rotation locking mechanism is locked, the rotation angle seat is fixedly connected to the rotation fixing seat. The step angle-adjusting and clamping mechanism is disposed between the rotation angle seat and the rotation fixing seat.

1. A device for quick splicing of a display screen, comprising:
a left assembly and a right assembly, the left assembly and the right assembly being lockable with each other, the left assembly comprising:
a rotation fixing seat, a rotation angle seat, and a rotation locking mechanism, the rotation angle seat being lockable with the right assembly and being rotatably connected to the rotation fixing seat, the rotation locking mechanism being disposed between the rotation fixing seat and the rotation angle seat, wherein when the rotation locking mechanism is unlocked, the rotation angle seat rotates relative to the rotation fixing seat; and when the rotation locking mechanism is locked, the rotation angle seat is fixedly connected to the rotation fixing seat; wherein the device for quick splicing of a display screen further comprises:
a step angle-adjusting and clamping mechanism, the step angle-adjusting and clamping mechanism being disposed between the rotation angle seat and the rotation fixing seat, wherein the rotation angle seat is provided with an arc-shaped flange, and the rotation fixing seat is correspondingly provided with an arc-shaped flange guiding slot, the arc-shaped flange is slidable in the arc-shaped flange guiding slot, such that the rotation fixing seat and the rotation angle seat are rotatable with respect to each other, the rotation locking mechanism comprises a locking plate and a locking driving mechanism, the locking plate defines three holes, the rotation fixing seat is provided with a guide column, the locking plate is inserted by the guide column, through one of the holes, the locking plate is slidably disposed on the guide column of the rotation fixing seat; the step angle-adjusting and clamping mechanism comprises arc-shaped tooth portions disposed on one side of the locking plate and accordingly disposed on one side of the arc-shaped flange of the rotation angle seat; and the step angle-adjusting and clamping mechanism drives the locking plate toward the rotation angle seat, such that the arc-shaped tooth portions of the locking plate and the rotation angle seat engage with each other to prevent the rotation fixing seat from rotating with respect to the rotation angle seat.
