Description

Outdoor LED is module for display screen

Technical Field

The utility model relates to a LED display screen technical field, concretely relates to when can increasing the encapsulating gap department glue is mobile outdoor module for LED display screen.

Background

The LED display screen is a comprehensive product of electronic technology, computer technology, information technology and photoelectric technology, and can be fully used for multimedia information distribution. The LED electronic screen media increasingly becomes the development trend of the 21 st century advertising industry, is advertisement display equipment with audio and video functions, belongs to the leading high-tech products of China, and is mainly used for outdoor advertisements, stations, squares, markets and the like. The LED display screen is generally formed by splicing unit boxes, the unit boxes are formed by splicing unit modules, and a main display part is a display screen unit module.

At present, a front lamp panel of an outdoor LED display screen module needs to be filled with a silica gel layer for water prevention, a waterproof rubber pad is added outside to block rainwater outside and prevent the rainwater from entering a box body, for example, a module for an outdoor LED display screen of Chinese patent 201420436395.5, which comprises a waterproof rubber pad, a bottom shell and a face mask; the bottom shell is fixedly connected with a box body through screws, and the waterproof rubber mat is arranged between the box body and the bottom shell; a water guide groove is formed around the bottom shell, and a plurality of water guide holes are formed at the bottom end of the water guide groove; the face mask is fixedly connected with the bottom shell through screws, and the periphery of the face mask and the periphery of the bottom shell are fixedly connected through buckle assemblies.

However, the existing liquid glue for pouring has the defects of poor glue flowability and poor glue pouring effect at the gap during glue pouring, so that the structure of the glue pouring position needs to be improved.

Based on this, this application provides a gap department glue mobility's for outdoor LED display screen module when can increase the encapsulating.

SUMMERY OF THE UTILITY MODEL

To prior art's defect, the utility model provides an outdoor module for LED display screen, it has set up the frame that has corrugated drainage structure, can increase the mobility of gap department encapsulating, and the encapsulating is effectual, rain-proof water can the reinforce.

In order to realize the above-mentioned purpose, the utility model provides an outdoor module for LED display screen, including drain pan, face guard and circuit board, face guard detachable establishes on the drain pan, its characterized in that, drain pan include the drain pan body and form the frame in the positive one side of drain pan body, and the circuit board is immersed between drain pan body and face guard to wrapped up by the frame, an at least medial surface of frame is equipped with and is used for increasing the mobile corrugated drainage structure of gap department encapsulating.

The above technical scheme of the utility model, through setting up corrugated drainage structure, can improve the mobility of gap department encapsulating, the encapsulating is effectual, has solved the waterproof problem that current module for outdoor LED display screen brought because of the encapsulating is bad, avoids appearing the potential safety hazard, increases reliability and stability that the display screen used.

According to another embodiment of the present invention, four inner sides of the outer frame are provided with corrugated drainage structures.

According to another embodiment of the present invention, the drainage structure is a curved boss and/or a curved groove formed on the inner side surface of the outer frame.

According to the utility model discloses a another kind of embodiment, be equipped with the guiding gutter around the drain pan body, the tank bottom of guiding gutter is equipped with a plurality of wash ports, and wherein, preferentially, the frame forms a guiding gutter lateral wall to the simplified structure.

According to another embodiment of the present invention, the plurality of drainage holes are distributed in a linear array.

According to the utility model discloses a another kind of embodiment, interconnect through the bolt between face guard and the drain pan to the realization is fixed to the stability of circuit board.

The utility model discloses possess following beneficial effect:

the utility model discloses set up corrugated drainage structure, the flow of gap department glue when effectively having increased the encapsulating for encapsulating speed has had obvious promotion, and the encapsulating effect is better, and the leakproofness is stronger, and water-proof effects is better, has solved the waterproof problem that current module for outdoor LED display screen brought because of the encapsulating is bad, avoids appearing the potential safety hazard, increases reliability and stability that the display screen used.

In addition, the water guide grooves are additionally arranged on the periphery of the bottom shell body, drain holes are formed in the bottoms of the water guide grooves, rainwater can be quickly drained, rainwater is prevented from entering an installation box body of an outdoor LED display screen, and the waterproof effect is good.
