Abstract
The utility model discloses a lamp bar trough used for fixing a PCB lamp panel in an LED curtain wall display screen, relating to the technical field of LED curtain wall display screens and solving the problems that the existing strip-shaped lamp panel trough is easy to be extruded and deformed, the smoothness of a mask is difficult to control, the LED lamp is easy to sink into the mask, thus influencing the normal display. The lamp bar trough comprises a body, wherein the body is provided with a strip-shaped lamp panel trough used for fixing the PCB lamp panel, and the strip-shaped lamp panel trough is internally provided with a screw connecting part; the lamp bar trough is characterized in that the screw connecting part is arranged on the bottom surface of the strip-shaped lamp panel trough, and gaps are reserved among the screw connecting part and two side walls of the strip-shaped lamp panel trough, wherein the gaps are capable of leading the mask on the PCB lamp panel to be extruded therein when the PCB lamp panel is fixed. The extrusion part of the mask enters the gaps among the screw connecting part and two side walls of the strip-shaped lamp panel trough, thus preventing the deformation of the two side walls of the strip-shaped lamp panel trough due to extrusion, and not having hunch-up phenomenon; and the surface of the mask is smooth.
Description
Technical field
The utility model relates to LED curtain wall display screen technology field, is specifically related to be used for fixing the lamp bar groove of PCB lamp plate.
Background technology
Shown in Fig. 1, at present, the lamp bar groove 1 ' that is used for fixing the PCB lamp plate generally is to establish a groove 12 ' at the bottom land of strip light board slot 11 ', and groove 12 ' is as the screw attaching parts that are used for being connected with fixing screw 2 '.When assembling, earlier the PCB lamp plate is located in the soft plastic cement face shield, then, reinstall in the strip light board slot 11 ', be fixed in the strip light board slot 11 ' by screw 2 ', and in screw 2 ' fixation procedure, because screw 2 ' is to the extruding of face shield, the two side of strip light board slot 11 ' is extruded distortion easily, and except that screw 2 ' the corresponding face shield position, arching upward also appears in face shield other position easily, the not only difficult control of the flatness of face shield, and to come off the LED through hole from face shield also can appear in the LED lamp on the PCB lamp plate, is absorbed in the face shield, influences display effect.
Summary of the invention
In sum, the purpose of this utility model is to solve the lamp bar groove of the existing PCB of being used for fixing lamp plate when assembling, the strip light board slot is extruded distortion easily, the difficult control of the flatness of face shield, LED lamp on the PCB lamp plate is absorbed in the face shield easily, influence is the problem of demonstration normally, and is used for fixing the lamp bar groove of PCB lamp plate in a kind of LED curtain wall display screen that proposes.
For solving the utility model the problem of proposition is arranged, the technical scheme that adopts is: the lamp bar groove that is used for fixing the PCB lamp plate in the LED curtain wall display screen, comprise: body, on described body, be provided with the strip light board slot that is used for fixing the PCB lamp plate, in described strip light board slot, be provided with the screw attaching parts, it is characterized in that: described screw attaching parts are located on the bottom surface of strip light board slot, remain with between the two side of screw attaching parts and strip light board slot fixing PCB lamp plate the time, the gap that the face shield on the PCB lamp plate is pressed into.
As to the further improved technical scheme of the utility model being: described screw attaching parts are the strip-shaped clamp groove that the two side parallels with strip light board slot two side.
Described strip-shaped clamp groove length is equal to or less than the strip light board slot, is located at strip light board slot center.
Described strip light board slot two side is a ledge structure, and the notch position width is greater than bottom land position width.
The beneficial effects of the utility model are: the utility model is in assembling process, after the face shield of encapsulation PCB lamp plate is subjected to the screw extruding, the part that face shield squeezes out enters into the gap of the two side of screw attaching parts and strip light board slot, prevent the two side crimp of strip light board slot, the phenomenon that arches upward can not appear, the face shield surfacing yet.
Description of drawings
Fig. 1 is the structural representation of the lamp bar groove 1 of existing fixed PCB lamp plate.
Fig. 2 is a perspective view of the present utility model.
Fig. 3 is a cross section structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred specific embodiment, structure of the present utility model is further described: shown in Fig. 2 and Fig. 3, comprise: body 1, body 1 is a strip structure, on body 1, be provided with the strip light board slot 11 that is used for fixing the PCB lamp plate, on bottom center's line of described strip light board slot 11, also be provided with the strip-shaped clamp groove 12 that a two side parallels with strip light board slot 11 two sides.Remain with an interspace 13 respectively between two madial walls of 12 liang of lateral walls of strip-shaped clamp groove and strip light board slot 11, fixing PCB lamp plate the time, after inserting, the face shield upper surface of screw 2 from the PCB lamp plate be screwed into the strip-shaped clamp groove 12, after 2 pairs of face shields of screw are exerted pressure, the gap 13 that the part that face shield squeezes out enters into, avoid the 11 two side crimps of strip light board slot, or the local phenomenon that arches upward occurs.Strip-shaped clamp groove 12 is than establish the more convenient operation of fixed screw pillar in the anti-groove of strip light 11 bottom surfaces, and is compatible strong.Strip light board slot 11 two sides are ledge structure, and the notch position width is greater than bottom land position width.
