Description

Technical Field

[0001] The utility model relates to the technical field of electronic display screens, in particular to a hollow display screen buckle mask. Background Art

[0002] With the development of the times, LED display screens are widely used in government squares, National Day celebrations, leisure squares, large entertainment squares, bustling commercial centers, advertising information boards, commercial streets, railway stations, waiting rooms, performing arts centers, TV live broadcasts, exhibition venues, concerts and other places.

[0003] At present, the main way to fix the LED display screen mask is screw fixing. The screws need to be evenly arranged and the intervals cannot be too large, otherwise the mask will be deformed by heat and affect the display effect of the screen. In order to obtain the maximum transmittance, the hollow display screen has made a large area of ​​hollow processing on the mask. In order to ensure the maximum transmittance, most areas of the mask cannot be fixed with screws, and it is still necessary to consider limiting the thermal deformation of the mask to avoid the formation of regional shadows at the light-emitting angles of the lamp beads. Therefore, a new mask structure is urgently needed to replace the traditional screw fixing structure. Utility Model Content

[0004] In view of this, a hollow display screen snap-on mask is provided which is easy to assemble and disassemble, can limit thermal deformation of the mask and has high light transmittance.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is: a hollow display screen snap-on mask, comprising a hollow bottom shell, a snap-on mask detachably connected to the hollow bottom shell, and an LED light board covering the snap-on mask and the hollow bottom shell, the snap-on mask comprising a snap-on mechanism, the snap-on mechanism comprising a plurality of snaps, the hollow bottom shell comprising a bottom shell hanging platform, the bottom shell hanging platform comprising a plurality of bottom shell hanging columns, the bottom shell hanging platform also comprising a plurality of groups of longitudinally arranged transverse support strips, the bottom shell hanging columns being arranged between the transverse support strips, the two sides of the bottom shell hanging columns being connected with the transverse support strips, the lower edge of the bottom shell hanging columns being wedge-shaped, the snaps corresponding to the bottom shell hanging columns one by one, the lower edge of each of the snaps having two inwardly hooked barbs, the barbs being buckled with the lower edge of the bottom shell hanging columns.

[0006] Furthermore, the LED light board is provided with a plurality of lights arranged in an array at equal distances in both horizontal and vertical directions, and the buckle mask has lamp holes corresponding to the positions of the lights for accommodating the lamps.

[0007] Furthermore, the buckles are distributed in the middle of the buckle mask and are spaced apart from the lamp holes.

[0008] Furthermore, the barb comprises a hook tip and a barb slope, the hook tip is located above the barb slope, and the two barb slopes form an outwardly expanding figure-eight flared opening in the shape of a trumpet.

[0009] Furthermore, each of the bottom shell hanging columns is provided with two hanging column inclined surfaces at the lower edge, and the two hanging column inclined surfaces form an inner eight-shaped buckling position, and the bottom shell hanging column also includes the upper edge corners of the hanging column and the side walls of the hanging column. When buckled, the buckle mask is pressed down vertically, and the barbed hook inclined surface contacts the upper edge corners of the hanging column. Under the action of pressure, the hook tip expands outward to contact the side wall of the hanging column, and continues to press down, and the hook tip hooks the hanging column inclined surface. At this time, the buckle is buckled with the bottom shell hanging column, and the buckle mask is flush with the hollow bottom shell.

[0010] Furthermore, when removing, the snap mask is lifted vertically upward, and the hook tip contacts the inclined surface of the hanging column. Under the action of the lifting force, the hook tip expands outward to contact the side wall of the hanging column, and continues to lift up, and the inclined surface of the hook is separated from the upper edge corner of the hanging column. At this time, the snap mask is separated from the hollow bottom shell.

[0011] Furthermore, the width of the bottom shell hanging column is greater than the minimum spacing of the bell-mouth-shaped buckling opening and smaller than the maximum spacing of the bell-mouth-shaped buckling opening.

[0012] Furthermore, the length of the bottom shell hanging column is smaller than the distance from the upper edge of the buckle to the hook tip.

[0013] Furthermore, the hollow bottom shell also includes a limiting column, and the LED light board is provided with a limiting hole corresponding to the position of the limiting column.

[0014] Furthermore, the buckle and the frame of the buckle mask connected to the buckle are integrally formed by injection molding, and the bottom shell hanging column and the frame of the hollow bottom shell connected to the bottom shell hanging column are integrally formed by injection molding.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects: the buckle mechanism of the hollow display screen buckle mask design replaces the traditional screws to fix the mask, which can limit the deformation of the mask due to heat, and the buckle mechanism is easier to assemble and disassemble than the traditional screw fixation, and has higher work efficiency. Moreover, since the buckle and the frame connected to it are injection molded as one piece, the buckle is not easy to be lost. BRIEF DESCRIPTION OF THE DRAWINGS
