Abstract
The utility model discloses a bottom beam structure for display screens. The bottom beam structure for the display screens comprises a bottom beam body and a bottom beam rear cover. The bottom beam rear cover is provided with a signal input interface. A ground wire connector bar and a null wire connector bar are arranged in a power switch box. A general power input end is connected with a general power input connector, and an external power source is connected out of an earth leakage circuit breaker through the general power input end by using the general power input connector directly. A ground wire is connected into the ground wire connector bar, a live line and the null line are connected into the input end of the earth leakage circuit breaker, a null line at the output end of the earth leakage circuit breaker is directly connected into the null wire connector bar, and the live line is connected into an air switch. The input end of the air switch is used for supplying electricity to each display screen through a power supply power line and a single display screen power supply plug. Display screen signals enable each display screen to be connected in series through a signal line and a signal line plug and then are connected with external input video signals through the signal input interface. The bottom beam structure for the display screens is overall concise and attractive, the wiring process is omitted during field insulation by workers, and mounting time is saved.
Description
Technical field
The utility model relates generally to display screen and manufactures field, relates in particular to the structure of bottom girder that a kind of display screen is used.
Background technology
Indoor LED display, in the time of assembling, need to be installed a fixing bottom girder at bottommost, and all screen bodies superpose assembled on this basis, and display screen power supply is divided into multichannel and is connected to respectively Special distribution cabinet from outside cabling, by the unified power supply of controlling of power distribution cabinet.Signal is directly drawn by screen body, install loaded down with trivial details, and whole screen body is power supply and signal wire behind everywhere, seriously draw shadow outward appearance, for this phenomenon, patent ZL201320171774.1 proposes a kind of concealed termination, and signal and power lead unified interface are connect in succession by shielding body internal direct, avoid power supply and signal connectivity problem between single casing and casing, be connected to Special distribution cabinet but the power supply of whole screen still needs many.
Utility model content
The utility model object is exactly the defect in order to make up prior art, in order further to optimize whole screen, the structure of bottom girder that provides a kind of new display screen to use, the electrical connection of all display screens is incorporated into bottom girder inside by it, and being connected to the switch control box being fixed on bottom girder, outside is directly by a civil power input.Synchronous signal is also exported separately by bottom girder privileged site, makes whole display screen body only have a power lead to be connected with a signal wire behind, and entirety is succinctly attractive in appearance, and the wiring process saved while installing at the scene of workman, saves the set-up time.
The utility model is achieved through the following technical solutions:
The structure of bottom girder that a kind of display screen is used, it is characterized in that: include bottom girder body, bottom girder bonnet, bottom girder body is provided with power switch box, display screen box body clip, single display screen Power supply plug, general supply input end, bottom girder bonnet is provided with signal input interface, in power switch box, be provided with ground wire line bank, zero line line bank, between ground wire line bank and zero line line bank, be also provided with earth leakage circuit-breaker, air switch, court of a feudal ruler Time Controller, general supply input end connects general supply input adapter, external power source directly utilizes general supply input adapter access earth leakage circuit-breaker by general supply input end, on ground wire access ground wire line bank, the input end of live wire and zero line access earth leakage circuit-breaker, the output terminal zero line of earth leakage circuit-breaker directly accesses zero line line bank, live wire access air switch, air switch input end is each display screen power supply by power supply line and single display screen Power supply plug respectively, display screen signal will be connected outside incoming video signal by signal input interface after each display screen series connection by signal wire with signal wire plug.
The structure of bottom girder that described display screen is used, is characterized in that: described air switch is substituted by direct current or A.C. contactor.
The utility model has the advantages that:
1, cancel the utilization of former display screen power distribution cabinet and be built in the power switch box replacement on bottom girder, save cost, be convenient to production scene and install.
2, power switch box is provided with creepage protection function, prevents the safety problem causing because of power issue.
3, air switch can use and exchange or D.C. contactor, can realize a long-range bond switching screen.
4, switch while being provided with the court of a feudal ruler in power switch box, can realize the power supply of whole display screen subsection, the power surges while reducing switch, protection display screen power supply.
5, signal wire unification collects to bottom girder place, and the combination with hidden formula mode of connection makes whole screen more elegant in appearance, and any mixed and disorderly electric wire is can't see at back completely.
