Abstract

The utility model relates to an outdoor LED display module for preventing glue leakage during glue filling. The outdoor LED display module comprises a front lamp panel and a bottom shell, the front lamp panel is embedded in the bottom shell, the glue filling step is that the surface of the front lamp panel is filled with a waterproof silica glue layer, a plurality of air cavities communicated through air guiding grooves are formed in the bottom shell, and the other portions in the bottom shell are attached to the front lamp panel; a plurality of needle inserting holes are formed in the bottom of one air cavity, and a sealing cover for plugging the needle inserting holes is arranged outside the positions, where the needle inserting holes are formed, of the bottom shell. According to the outdoor LED display module for preventing glue leakage during glue filling, the air cavities communicated through the air guiding grooves are designed in the bottom shell, the sealing cover is additionally arranged to enable air in the air cavities in the bottom shell not to be communicated with outside air, glue is prevented form being leaked into the bottom shell when glue filling is carried out, the sealing cover is taken away after the glue is solidified, the air pressure in the bottom shell is kept balanced with the outside pressure through the needle inserting holes, and the outdoor LED display module is simple in structure, convenient to operate and good in effect.

Description

A kind of outdoor LED display screen module that prevents encapsulating hourglass glue

Technical field

The utility model relates to LED display module, particularly a kind of outdoor LED display screen module that prevents encapsulating hourglass glue.

Background technology

The front lamp plate of outdoor LED display screen module need to pour into layer of silica gel and carry out waterproof, before the liquid glue of original perfusion, need first sealing to be filled up to glass cement in the gap between front lamp plate and drain pan, there is following defect: each module need to expend the benefit glue time of approximately 15 minutes, and production efficiency is low; When mending, glue position is improper or while omitting, and can cause that glue bleeds in shell, causes product to be done over again; The weight of mending glue can be subject to the quantitative limitation of customer requirement product gross weight; Fill up glass cement and easily stain product appearance, rear operation also can increase manually product is cleaned and checked, increases production cost.

Utility model content

For overcoming the shortcomings and deficiencies of above-mentioned prior art, the utility model provides a kind of outdoor LED display screen module that prevents encapsulating hourglass glue.

The scheme that the utility model adopts is:

An outdoor LED display screen module that prevents encapsulating hourglass glue, comprises front lamp plate and drain pan, and described front lamp plate embeds in drain pan; Described encapsulating is at front lamp plate surface perfusion one deck water-proof silica-gel layer; In described drain pan, be provided with some air cavitys that are communicated with by air slot, other positions and the laminating of front lamp plate in drain pan; One of them air cavity bottom is provided with some cushions hole, and the drain pan outside at place, cushion hole is provided with the gland bonnet of a clog needle jack.

Preferably, in the front lamp plate of described and cushion hole correspondence position, be provided with needle socket, gland bonnet is provided with corresponding fine needle, and the fine needle on described gland bonnet is by cushion hole insertion needle socket.

Further preferred, described drain pan and front lamp plate are provided with some light holes at the position fitting.

The beneficial effects of the utility model are: the outdoor LED display screen module that prevents encapsulating hourglass glue described in the utility model, in drain pan, design some air cavitys that are communicated with by air slot, increasing gland bonnet does not circulate the interior air cavity of drain pan and outside air, prevent that glue leaks in drain pan when encapsulating, after glue curing, take again gland bonnet away, by cushion hole, keep drain pan internal gas pressure and the outside balance that keeps, simple in structure, easy to operate, respond well.

Embodiment

For convenience of those skilled in the art, understand technology contents of the present utility model, below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, the outdoor LED display screen module that prevents encapsulating hourglass glue that the utility model discloses, comprises front lamp plate 1 and drain pan 2, and described front lamp plate 1 embeds in drain pan 2; As shown in Figures 2 and 3, in described drain pan, be provided with some air cavitys that are communicated with by air slot 43, other positions and the laminating of front lamp plate in drain pan 1; Topmost the bottom of an air cavity 3 is provided with some cushions hole 5.As described in as shown in Fig. 2 and 4, drain pan and front lamp plate are provided with some

light holes

61,62 at the position fitting, and improve the display effect of module.

The utility model is when front lamp plate 1 surface perfusion one deck water-proof silica-gel layer, in the drain pan outside at 5 places, cushion hole, be provided with the gland bonnet of a clog needle jack, in the front lamp plate of described and cushion hole 1 correspondence position, be provided with needle socket, gland bonnet is provided with corresponding fine needle, fine needle on described gland bonnet inserts needle socket by cushion hole, fine needle root is provided with elastic sealant, the interior air cavity of drain pan and outside air are not circulated, prevent that glue leaks in drain pan when encapsulating, after glue curing, take again gland bonnet away, by cushion hole, keep drain pan internal gas pressure and the outside balance that keeps.

Light hole

61,62 use rubber plugs are blocked during encapsulating more in addition, etc. after glue curing, rubber plug being taken out.

Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
