Description

The LED screen body structure of fast demountable

Technical field:

The utility model relates to the structure of LED display, relates in particular to the LED body structure of fast demountable.

Background technology:

Continuous progress along with society; LED display begun to be applied to various theatrical evenings, celebration, sales promotion popularization, news briefing, display and demonstration, party party, competition match, fashion show, various meeting widely, the position of contracting, go into operation and lay a foundation, cut the ribbon at an opening ceremony in the meeting and activity of opening, Festival celebration Festival, square culture, fashion show, advertising or the like all kinds of forms, and LED display great majority wherein all are to provide with the form of leasing.Sort of activity is owing to time and place are reasons such as interim uses, the equipment that is given to install and the time of debugging at full stretch often, the LED display of leasing usefulness is too.Therefore, just require LED display, can safe and reliablely carry out fast assembling-disassembling,, reserve more time and give equipment debugging and movable rehearsal to lower the labour intensity of installation personnel as far as possible cheaply under the situation.

At present common LED lease display screen box body, for the mode of connection and the assembly unit requirement that reaches the desired signal of interim installation, feed cable, the more complicated of structural design, the whole aluminium diecasting mode of the usefulness that has, cost is expensive.Very thick with the sheet metal box body structural design that has increases a lot of supplementary structure spares again, makes the whole box body structure seem very heavy, and labour intensity is very big during installation.Therefore, body structure safe, light, the LED that can fast install and dismantle lease display screen is the pursuit of industry always.

Summary of the invention:

The purpose of the utility model is to provide a kind of LED screen body structure of fast demountable.

It comprises that the LED that a plurality of LED unit boxs (14) and LED display framework (19) are formed shows module (18); The back of each LED unit box (14) is provided with panel beating shell on the back (9); Each LED unit box (14) frame all around is provided with lower box bonnet lock hole (5), last lower box register pin (15), casing fastener hole, the left and right sides (17) respectively, goes up lower box snap close (16); Fastener (1) is set laterally connects two adjacent LED unit boxs (14), last lower box register pin (15) vertically is connected two adjacent LED unit boxs (14) with last lower box snap close (16) and forms LED unit box (14) combination.

Fastener (1) is provided with LED unit box (14) both sides bayonet socket (2), the middle bayonet socket (3) of installing of LED unit box (14) is installed.

The and arranged on left and right sides of panel beating shell on the back (9) is provided with L shaped stiffener A (4) and L shaped stiffener B (8); Lower box bonnet lock hole (5), signal cable hole (6), panel beating shell on the back fixed orifice (7) are set on the L shaped stiffener A (4); Lower box bonnet lock hole (5), panel beating shell on the back fixed orifice (7) are set on the L shaped stiffener B (8).

Panel beating shell on the back (9) is provided with hanging wire mouth (10), feed cable entrance hole (11), louvre (12), feed cable wire hole (13).

The utility model adopts non-bolt casing connected mode; Box house adopts double L-shaped asymmetric panel beating stiffener structure; Not only can strengthen the casing integral intensity, make casing satisfy lifting requirements, and play the effect that increases casing LED module mounting plane flatness.Also made things convenient for simultaneously the plug of signal and feed cable.Be designed with signal jack, supply hub and enough louvres on the panel beating shell on the back.The signal of LED display board and power supply are through custom-designed switching circuit board transmission.Make frivolous succinctly attractive in appearance, the good heat dissipation effect of whole box body, cable plug convenient and simple.The dual-mouth design of fastener also can firmly, reliably reach LED screen edge casing partly and is fixed on the display frame efficiently.Whole screen casing is installed and is not needed any bolt.The size that changes casing, stiffener and panel beating shell on the back can expand to the mounting structure of the LED display of various different sizes.Has very strong versatility.Owing to reduced the thickness of LED display casing; Therefore alleviated the weight of LED display casing; Reduce material cost, manufacture difficulty and on-the-spot labour cost, can accelerate on-the-spot installation rate, increased reliability, security and agility that LED display is installed.
