Description

Technical Field

[0001] The utility model relates to the technical field of display screen assembly, in particular to a bevel bottom shell clamping structure. Background Art

[0002] In the production process of conventional display modules, a tray clamping fixture is used to fix the bottom shell, making it convenient to pass the screws through the back of the bottom shell and lock it with the PCB board.

[0003] With the continuous improvement of customer requirements and different application scenarios, special-shaped screens such as the Rubik's Cube screen have appeared on the market. The main component of the special-shaped screen is the right-angle screen module. In order to facilitate the splicing between modules, the bottom shell of the right-angle screen module is treated with inclined surfaces on both sides, so it is called a beveled bottom shell. Compared with conventional display screen modules, during the production and assembly process of the beveled bottom shell, due to the existence of the inclined surface, there will be a gap or a small contact area between the edge of the bottom shell and the jig, resulting in the jig being unable to clamp the bottom shell, and the seesaw phenomenon is prone to occur when the screws are locked, which in turn leads to a decrease in the production line pass rate and product quality.

Preferably, the roots of the opposite surfaces of the two clamping arms are both provided with a first groove; the tops of the opposite surfaces of the two clamping arms are both provided with a first inclined surface.

[0011] Alternatively, the elastic part is two elastic arms formed on the upper part of the clamping block; the fixing part is a slot formed on the back of the bottom shell; the two elastic arms are embedded in the slot and tightly fit with the two side walls of the slot.
