Embodiment
In order to clearly, complete explanation the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
In the present invention, when not doing contrary explanation, the noun of locality of use if " upper and lower " is normally for direction shown in the drawings, or for vertically, on vertical or gravity direction; Similarly, for ease of understanding and describing, " left and right " is normally for shown in the drawings left and right; " inside and outside " refers to profile inside and outside relative to each parts itself, but the above-mentioned noun of locality is not limited to the present invention.
As shown in Figure 1 to Figure 3, the utility model proposes a kind of detent mechanism of LED display Fast Installation module, it comprises drain pan location division 10 and casing location division 20, described drain pan location division 10 comprises the installation portion 11 being located at the drain pan back side, and described installation portion 11 comprises a pair transverse side 111 and a pair longitudinal side 112.Described casing location division 20 comprises mounting hole 21, and described installation portion 11 is contained in described mounting hole 21.
As shown in Figure 3, compared with prior art, in this example, described drain pan location division 10 also comprises a pair located lateral rib 12 and a pair longitudinal register rib 13, to be connected with the outside of described a pair transverse side 111 near the two ends that described a pair located lateral rib 12 is symmetrically set in the cross central line 14 of described installation portion 11, to be connected with the outside of described a pair longitudinal side 112 near the two ends of the longitudinal centre line 15 of the symmetrical described installation portion 11 of described a pair longitudinal register rib 13; Described casing location division 20 also comprises a pair horizontal mounting hole 22 and a pair longitudinal mounting hole 23, described a pair horizontal mounting hole 22 is positioned at the described mounting hole 21 side position corresponding with described a pair located lateral rib 12 and coordinates with described a pair located lateral rib 12, described a pair longitudinal mounting hole 23 is positioned at the described mounting hole 21 side position corresponding with described a pair longitudinal register rib 13 and coordinates with described a pair longitudinal register rib 13, and described a pair horizontal mounting hole 22 and described a pair longitudinal mounting hole 23 are through with mounting hole 21.
In this example, detent mechanism to coordinate on the basis of locating with the mounting hole 21 of casing at the installation portion 11 of drain pan, also be provided with four location ribs to coordinate with the mounting hole of four on mounting hole 21 locate in the outside in installation portion portion, make the more accurate positioning between drain pan and casing like this, and then make the gap between LED display module be easy to be consistent, can effectively avoid the phenomenon of bright concealed wire to occur.And increase by four location ribs, the installation between drain pan and casing is located also more convenient, improve installation effectiveness.
In this example, described installation portion 11 is a square boss at the back side on drain pan as shown in Figure 1, and described a pair located lateral rib 12 and a pair longitudinal register rib 13 are the elongate strip contour with described installation portion 11 grown at four sides of installation portion 11.It is one-body molded that described installation portion 11 and four locate rib, can reduce the orientation factor between installation portion 11 and mounting hole 21 like this and locate the error between the orientation factor between rib and mounting hole, make the location between drain pan and casing more accurate.
In this example, described a pair located lateral rib 12 and described a pair horizontal mounting hole 22 are between 0.01-0.50mm in the fit-up gap of longitudinal direction, are greater than 0.01mm in the tolerance clearance of transverse direction.When drain pan expanded by heating, its dilatational strain in the horizontal can be out of shape along the gap between a pair located lateral rib 12 and a pair horizontal mounting hole 22.In the vertical, because a pair located lateral rib 12 of drain pan is less with the gap of a pair horizontal mounting hole 22 of casing, therefore, can think like this, drain pan is when expanded by heating is out of shape, and drain pan datum of deformation is in the vertical the line of centres of drain pan a pair located lateral rib 12 transversely.
In this example, described a pair longitudinal register rib 13 and described a pair longitudinal mounting hole 23 are between 0.01-0.50mm in the fit-up gap of transverse direction, are greater than 0.01mm in the tolerance clearance of longitudinal direction.When drain pan expanded by heating, its dilatational strain in the vertical can be out of shape along the gap between a pair longitudinal register rib 12 and a pair longitudinal mounting hole 22.In the horizontal, because a pair longitudinal register rib 12 of drain pan is less with the gap of a pair longitudinal mounting hole 22 of casing, therefore, can think like this, drain pan is when expanded by heating is out of shape, and drain pan datum of deformation is in the horizontal the line of centres of drain pan a pair longitudinal register rib 12 transversely.
Comprehensive above 2 points, can think like this, drain pan (LED display module) is when expanded by heating is out of shape, and the benchmark of distortion is: on the intersection point of drain pan a pair located lateral rib 12 line of centres and a pair longitudinal register rib 13 line of centres.Arbitrfary point on drain pan (LED display module) is all be out of shape as benchmark according to linear expansion.Making the distortion of module have benchmark to be out of shape from becoming without benchmark like this, can effectively avoid lighting under duty because thermal expansion brings the problem such as module arch camber, bright concealed wire phenomenon.
In this example, four location ribs of drain pan location division 10 all design near the cross central line 14 and longitudinal centre line 15 of installation portion 11, and not on centerline, so detent mechanism has foolproof function, namely installation direction is fixing.
In this example, the top of described a pair located lateral rib 12 and described a pair longitudinal register rib 13 is rounded down, and can make the easier for installation of LED display module like this, improve installation effectiveness.
Certainly, the utility model also can have other numerous embodiments, based on present embodiment, those of ordinary skill in the art under the prerequisite not making any creative work obtain other embodiments, all belong to the scope that the utility model is protected.
