Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 4, the present embodiment provides an LED display screen 1, the LED display screen 1 includes an LED lamp panel 100 and an LED display screen cover 200, wherein the LED lamp panel 100 includes a lamp panel main body 110 and a plurality of LED lamp beads 120 disposed on the lamp panel main body 110, the LED display screen cover 200 includes a cover main body, the cover main body has a front surface 210 and a rear surface 220 opposite to each other, a plurality of rows of transverse grooves 211 and a plurality of columns of longitudinal grooves 212 are concavely disposed from the front surface 210 to the rear surface 220, each transverse groove 211 is communicated with the plurality of longitudinal grooves 212, each longitudinal groove 212 is communicated with the plurality of transverse grooves 211, the cover main body is divided into a plurality of lamp hole square platforms 21 by the plurality of rows of transverse grooves 211 and the plurality of columns of longitudinal grooves 212, and each lamp hole square platform 21 is provided with an LED lamp hole 22 penetrating through the front surface 211 and the rear.
In the present embodiment, as shown in fig. 1 to 4, the cross-sectional width of the transverse groove 211 gradually decreases from the front surface 210 to the rear surface 220 to form a V-shaped groove structure, so as to effectively enhance the longitudinal elastic deformation capability thereof. The cross-sectional width of the longitudinal groove 212 gradually decreases from the front surface 210 to the rear surface 220, and a V-groove structure is also formed to effectively enhance the transverse elastic deformation capability. A plurality of nodal pedestals 23 project from the rear face 220 of the mask body, each nodal pedestal 221 connecting the intersection of a transverse slot 211 and a longitudinal slot 212. The depth of the lateral groove 211 is greater than the distance between the front surface 210 and the rear surface 220 in a direction perpendicular to the front surface 210. In a direction perpendicular to the front surface 210, the depth of the longitudinal groove 212 is greater than the distance between the front surface 210 and the rear surface 220. Thus, a cross-shaped elastic structure 24 is formed at the intersection of the transverse groove 211 and the longitudinal groove 212. As shown in fig. 5 to 7, the original state schematic diagram, the stretching state schematic diagram and the shrinking state schematic diagram of the cross elastic structure 24 are sequentially shown, and it can be seen that the cross elastic structure 24 can absorb the elastic deformation of the mask in the horizontal and vertical directions, and prevent the mask from locally bulging, i.e. normal deformation, so as to ensure the flatness and consistency of the display screen. Simultaneously, because this cross elastic structure 24's design, the face guard is in installation and use, and four angles of cross elastic structure 24 can carry out automatically regulated according to LED lamp pearl 120 and LED lamp hole 22's relative position relation for each LED lamp hole 22 when the buckle is on corresponding LED lamp pearl 120 all the time, guarantee to LED lamp pearl 120 stress at a reasonable within range, can not cause LED lamp pearl 120's extrusion to destroy.
As shown in fig. 2 and 4, a plurality of connecting portions 25 for connecting adjacent lamp hole square bases 21 are protruded from the rear surface 220 of the mask body, each connecting portion 25 extends along the longitudinal groove direction, and each connecting portion 25 is located between two adjacent node bases 21 in the same longitudinal groove direction. The side of the connecting portion 25 remote from the rear surface 220 is curved. Through the structural arrangement of the connecting portion 25, on one hand, the connection between every two of the lamp hole square platforms 210 which are adjacent in the transverse direction can be enhanced, and on the other hand, the transverse elastic deformation capacity of the lamp hole square platforms can also be enhanced. A plurality of pairs of elastic clamping portions 26 are protruded from the rear surface 220 of the mask body, and each pair of elastic clamping portions 26 is located at two opposite sides of the longitudinal groove direction of each LED lamp hole 22. The distance between each pair of the resilient catches 26 becomes gradually smaller from the front surface toward the rear surface. Therefore, when each LED lamp bead 120 is correspondingly clamped in each LED lamp hole 22, the corresponding LED lamp bead 120 is extruded through each pair of corresponding elastic clamping parts 26, so as to enhance the friction force between the two, and further effectively fix the mask on the LED lamp panel, so that the purpose that the surface of the mask is not fixed by screws is achieved, and the mounting efficiency of the mask is greatly improved.
The embodiment of the utility model provides a LED display screen face guard and LED display screen, the face guard main part of its LED display screen face guard has relative front surface and rear surface, concave multirow horizontal groove and the multiseriate vertical groove of being equipped with towards this rear surface from this front surface, each horizontal groove is linked together with a plurality of vertical grooves, each vertical groove is linked together with a plurality of horizontal grooves, multirow horizontal groove and multiseriate vertical groove are cut apart into a plurality of lamp holes square platform with the face guard main part, set up the LED lamp hole that runs through front surface and rear surface on each lamp holes square platform. Therefore, the mask can be effectively fixed on the LED lamp panel through the friction force of the LED lamp holes to the LED lamp beads, the purpose that the surface of the mask is fixed without screws is achieved, and the mask installation efficiency is greatly improved. Simultaneously, the face guard main part is equipped with multirow transverse groove and multiseriate vertical groove from the front surface to the concave multirow longitudinal groove that is equipped with of rear surface, and move about freely and quickly and distribute between a plurality of lamp hole square platforms, this structure has local deformation coordination function, can absorb the elastic deformation of face guard plane violently indulges two directions, make its accumulation or the deformation concentration of hardly appearing stress, the phenomenon that the accumulation warp and lead to lamp pearl extrusion destruction can not appear like this, also can not appear the face guard because of warping the accumulation and lead to local bellied problem, thereby guarantee the roughness and the uniformity of display screen.
