A kind of LED display module face shield

Technical field

The utility model relates to a kind of LED display module face shield.

Background technology

The module face of LED display has face shield to install, and its effect is the LED of lamp edge protective sleeve in the panel through hole, shading, keeps off the rain and effectively reduces light to the impact of LED, makes us when watching the display screen with this face shield, and is more clear, more direct.Please refer to Fig. 1 to shown in Figure 3, it has shown a kind of structure of existing LED display module face shield: mask plate 1 is provided with buckle 11, buckle 11 is arranged on the right-angled intersection position between the adjacent lamp position hole 12, as shown in Figure 4, buckle 11 passes the pilot hole 21 on the LED pcb board 2, jut on the buckle 11 blocks the reverse side of LED pcb board 2, and mask plate 1 is fitted on the LED pcb board 2.

Yet, adopt existing this face mask structure that obvious defective is arranged, because the buckle of mask plate is arranged on the place of right-angled intersection of the pilot hole of mask plate, so in Design of Dies, must add side core-pulling mechanism, undercut is extracted the smoothly demoulding of side direction core rear out, and die cost can increase like this.And after extracting the side direction core out, because the mobile error that produced, the terminal gap with the mask plate reverse side of snap projection can be variant like this, can not fit tightly on the LED pcb board when causing mask plate to install, have the waste product of part, equally also increased production cost.

The utility model content

The purpose of this utility model is to provide a kind of LED display module face shield, and it can solve the high problem of production cost of prior art.

In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:

A kind of LED display module face shield, it comprises square mask plate, is provided with a plurality of LED lamp position holes of rectangular arrangement on the mask plate, a plurality of the first buckles, and a plurality of the second buckle; The first buckle is arranged on the upper limb of LED lamp position hole, and the second buckle is arranged on the lower edge of LED lamp position hole, and the first buckle, the second buckle all stretch out along the back side of mask plate; The first buckle, the second buckle are connected with the pilot hole buckle of LED pcb board respectively.

As preferred structure, on the longitudinal direction of mask plate, the first buckle and the second buckle interval arrange, and have several LED lamp position holes between the first buckle and the second buckle.At mask plate in a lateral direction, have several LED lamp position holes between the first adjacent buckle, have several LED lamp position holes between the second adjacent buckle.

As preferred structure, the first hook portion that described the first buckle comprises the first pole and is arranged on the first pole top, the second hook portion that described the second buckle comprises the second pole and is arranged on the second pole top, the first hook portion and the second hook portion towards the opposite.The first buckle and the second buckle are to arrange in pairs, behind the pilot hole that passes the LED pcb board, can make to be subjected to force direction even like this, and be unlikely to a wherein side of deflection.

Further preferred structure, the medial surface of the first pole is parallel with the lateral surface of the first pole, and the back side of the lateral surface of the first pole and mask plate forms angle; The medial surface of the second pole is parallel with the lateral surface of the second pole, and the back side of the lateral surface of the second pole and mask plate forms angle.The interior outside of the first buckle, the interior outside of the second buckle have respectively certain gradient moulding, make the first buckle, the second buckle pass the pilot hole of LED pcb board after because self elasticity, be stuck in firmly a side of pilot hole.

Further preferred structure, the first hook portion is to the thickness of the distance between the back side of mask plate less than the LED pcb board; The second hook portion is to the thickness of the distance between the back side of mask plate less than the LED pcb board.After the first buckle, the second buckle passed respectively LED pcb board pilot hole, the first buckle, the second buckle did not recover original shape fully, but also had a bit, and mask plate is fitted tightly on the LED pcb board.

As preferred structure, the first buckle, the second buckle are corresponding with the pilot hole dislocation of LED pcb board respectively, namely the tip position of the first buckle, the second buckle slightly has deviation with a side of the pilot hole of LED pcb board respectively, like this in the process of installing, the first buckle, the second buckle must tilt in the opposite direction, after the first buckle, the second buckle top boss are partly passed pilot hole, because the elasticity of himself recovery, thereby mask plate firmly is fixed on the LED pcb board.

The utlity model has following beneficial effect:

The first buckle, the second buckle lay respectively at upper limb, the lower edge of LED lamp position hole, be different from prior art buckle is arranged on right-angled intersection position between LED lamp position hole and the LED lamp position hole, so just can effectively simplify the mould structure of producing LED display module face shield of the present utility model, thereby the raising product qualified rate reduces production costs.
