Description

A kind of Novel LED display screen module positioning structure

Technical field

The utility model relates to LED field, particularly a kind of Novel LED display screen module positioning structure.

Background technology

The locator meams of LED display module is at present: the module drain pan back side arranges 2 positioning cylinders, two positioning round orifice is set on casing and coordinates with it simultaneously, and tolerance clearance (radially) is generally 0.05-0.2mm.This location structure has following deficiency:

1, because the material of drain pan and casing is different, drain pan generally adopts plastic material, and casing generally adopts the metal material such as aluminium or iron, and therefore their thermal expansivity is inconsistent, has larger difference.Therefore,, in the use procedure of LED display, along with the continuous rising of temperature, the thermal expansion amount of drain pan and casing is also different.If the difference of thermal expansion amount absolute value exceedes the tolerance clearance of drain pan positioning cylinder, due to the existence of reference column, limit expansion, module is easy to occur arch camber metaboly, and then affects display effect.

If the gap of 2 cylinder circular holes is larger, so, in the time starting to assemble, do not have positioning action at all, be only that mistake proofing effect is installed.

3, owing to only having two holes location, and due to the existence of fit-up gap, the object of expanded by heating, in the time of thermal expansion, cannot be determined the benchmark of dilatational strain.

4, owing to only having a direction location, therefore, in the time that module is installed, efficiency is lower, and very easily causes the gap of intermodule inconsistent, and then causes the phenomenon of bright concealed wire.

Above-mentioned many disadvantages requires us to provide a kind of Novel LED display screen module positioning structure to solve the above problems.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of Novel LED display screen module positioning structure, has solved in existing location structure LED display module locating effect poor, and the arch camber of easily expanding is difficult to determine the technological deficiencies such as expansion benchmark.

The utility model solves the technical scheme that its technical matters adopts:

A kind of Novel LED display screen module positioning structure, comprise drain pan and casing, described two ends, cross central line left and right, the drain pan back side are provided with two located lateral posts, the upper and lower two ends of longitudinal centre line, the drain pan back side are provided with two longitudinal register posts, described two ends, casing cross central line left and right are provided with two horizontally sets and coordinate the horizontal mounting hole of location with above-mentioned located lateral post, the upper and lower two ends of casing longitudinal centre line are provided with two longitudinal mounting holes that longitudinally arrange and coordinate with above-mentioned longitudinal register post location, described drain pan and casing coordinate behind location, located lateral post is placed in described horizontal mounting hole, longitudinal register post is placed in described longitudinal mounting hole.

Described horizontal mounting hole and the longitudinally length of straight flange of mounting hole are greater than 0.1mm, and laterally mounting hole and longitudinal width of mounting hole and the tolerance clearance of located lateral post or longitudinal register post are 0.01-0.5mm.

The beneficial effects of the utility model are: the utility model provides a kind of Novel LED display screen module positioning structure, this kind of location structure located drain pan, casing mutually by the located lateral post of horizontally set, laterally mounting hole and the longitudinal register post longitudinally arranging, longitudinal mounting hole, LED display module there will not be the situations such as arch camber distortion in use procedure, be conducive to protect whole LED display, improve the display quality of display screen; In addition, because horizontal and vertical both direction is all provided with reference column and pilot hole, therefore, in the time that module is installed, the gap of intermodule is easy to be consistent, can effectively avoid the generation of bright concealed wire phenomenon, this location structure can also make product more efficient in the time of location simultaneously, improves installation effectiveness.It is poor that this kind of Novel LED display screen module positioning structure solved in existing location structure LED display module locating effect, and the arch camber of easily expanding, is difficult to determine the technological deficiencies such as expansion benchmark.

Embodiment

A kind of Novel LED display screen module localization method:

Two ends, cross central line left and right, the drain pan back side at LED display module arrange two located lateral posts, simultaneously, the two ends, casing cross central line left and right of LED display module arrange two horizontally sets and coordinate the horizontal mounting hole of location with located lateral post, and located lateral post is placed in horizontal mounting hole;

The upper and lower two ends of drain pan backboard longitudinal centre line at LED display module arrange two longitudinal register posts, simultaneously, the upper and lower two ends of casing longitudinal centre line of LED display module arrange two longitudinal mounting holes that longitudinally arrange and coordinate with longitudinal register post location, and longitudinal register post is placed in longitudinal mounting hole.

With reference to Fig. 1-5, a kind of Novel LED display screen module positioning structure, comprise drain pan 1 and casing 2, described drain pan 1 two ends, cross central line left and right, the back side are provided with two located lateral posts 11, the drain pan 1 upper and lower two ends of back side longitudinal centre line are provided with two longitudinal register posts 12, described casing 2 two ends, cross central line left and right are provided with two horizontally sets and coordinate the horizontal mounting hole 21 of location with above-mentioned located lateral post 11, the casing 2 upper and lower two ends of longitudinal centre line are provided with two longitudinal mounting holes 22 that longitudinally arrange and coordinate with above-mentioned longitudinal register post 12 location, described drain pan 1 and casing 2 coordinate behind location, located lateral post 11 is placed in described horizontal mounting hole 21, longitudinal register post 12 is placed in described longitudinal mounting hole 22.

By located lateral post 11 and the laterally mating reaction of mounting hole 21, drain pan 1 expand time transversely mounting hole 21 be out of shape, dilatational strain amount is supplemented by horizontal mounting hole 21, and drain pan 1 datum of deformation is in the horizontal the line of centres of drain pan 1 two located lateral posts 11 transversely; In like manner, drain pan 1 in the time expanding along the longitudinal mounting hole 22 be out of shape, dilatational strain amount is supplemented by longitudinal mounting hole 22, drain pan 1 datum of deformation is in the vertical the line of centres of drain pan 1 two longitudinal register posts 12 on longitudinally; Therefore, drain pan 1 is in the time that expanded by heating is out of shape, and the benchmark of distortion is the intersection point of located lateral post 11 center lines and longitudinal register post 12 center lines.

In addition, because total has adopted the positioning action of horizontal and vertical both direction, this kind of product can be more prone to realize location, and assembling is efficient.

As the improvement of technique scheme, described horizontal mounting hole 21 and the longitudinally length of straight flange of mounting hole 22 are greater than 0.1mm, and laterally mounting hole 21 and longitudinal width of mounting hole 22 and the tolerance clearance of located lateral post 11 or longitudinal register post 12 are 0.01-0.5mm.
