Abstract
The utility model discloses an LED display screen which is mainly composed of a plurality of LED display screen modules. Each of the plurality of the LED display screen modules comprises a plate casing provided with reflection holes, LED chips and a circuit board, and is characterized in that a ring groove is arranged on the back face of the plate casing, and sealing gaskets are embedded in the ring groove. Screw holes and inserting holes are evenly distributed in the ring groove; and the screw holes are fixed in the ring groove through fixing tables. Plug pins and through holes are arranged on the sealing gaskets; and the plug pins correspond to the inserting holes and are inserted into the inserting holes correspondingly; sizes and shapes of the through holes are corresponding to the sizes and the shapes of the fixing tables, and the through holes are sleeved on the fixing tables correspondingly. As the main composition part, the plurality of the LED display screen modules have high water proof, dust proof and sun proof performances, accordingly, the plurality of LED display screen which is assembled by the plurality of the LED display screen modules can be subjected to long-term weather and dust exposure, and has low maintenance rate.
Description
Technical field
The utility model relates to the LED electronic technology field, specifically, relates to a kind of LED display curtain.
Background technology
The LED display curtain is that light harvesting electronic technology, microelectric technique, computer technology and video technique are the high-tech product of one; Its luminous component is assemblied to form by LED (being light emitting diode); Its advantage is that power consumption is few, brightness is high, WV is low, driving is simple, the life-span is long, stable performance; The area of display screen can be as required by any assembly unit of unit module, and response speed is fast.The LED display curtain has remedied the defective of information publication medium effects such as magnetic turnover panel, neon bulb in the past; Change abundant colors, pattern with it; The real-time and dynamic display mode; Perfect multimedia effect and powerful visual impact; Multiple modes such as information, literal, picture, animation and video are shown, become the epoch-making product that information is propagated, in railway, civil aviaton, stadiums, conference halls, highway, square, megastore, bank, securities market and multiple monitoring and scheduling, obtained using widely.
The LED display curtain mainly is made up of several LED display modules, and the waterproof and dustproof of existing LED display module, sun-proof ability are relatively poor, cause the LED display curtain to break down through regular meeting, and maintenance rate is high.
Summary of the invention
The technical matters that the utility model will solve is to overcome above-mentioned defective, and a kind of waterproof and dustproof, LED display curtain that sun-proof performance is strong are provided.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of LED display curtain mainly is made up of several LED display modules, and said LED display mould comprises plate shell, led chip and the circuit board that is provided with reflection hole, it is characterized in that: the back side of said plate shell is provided with annular groove, and annular groove is embedded with seal gasket.
Furtherly, be evenly distributed with screw and jack in the said annular groove; Screw is fixed in the annular groove through fixed station.
Furtherly, said seal gasket is provided with latch and through hole; Latch is corresponding with jack, and correspondence is plugged in the jack one by one; The size of through hole is corresponding with fixed station with shape, and correspondence is socketed on the fixed station one by one.
Owing to adopted technique scheme; Compared with prior art; Strong as the LED display module waterproof and dustproof of the utility model chief component and sun-proof performance; Thereby, being able to take long-term wind, Exposure to Sunlight, drenching with rain and dust by its assembled the utility model, maintenance rate is low.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of plate shell described in the embodiment of the utility model;
Fig. 2 is the structural representation of seal gasket described in the embodiment of the utility model.
