Embodiment

By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

Embodiment as the utility model LED display waterproof construction system, see also Fig. 1 to Fig. 4, thewaterproof pad 3 that comprises casing 1,demonstration module 2 and ring-type, the back of describeddemonstration module 2 is provided withannular ditch groove 21, and describedwaterproof pad 3 is arranged in theannular ditch groove 21 and is pressed in casing 1 and shows between themodule 2.

In the present embodiment, described casing 1 is made up of a plurality of sphere of movements for the elephants structures, and describeddemonstration module 2 is arranged in the sphere of movements for the elephants structure, and seamlessly is connected on the casing 1.

In the present embodiment,groove 21 places of describeddemonstration module 2 also are provided withfixed orifice 23, and describedwaterproof pad 3 is provided with thefixed leg 32 suitable with describedfixed orifice 23, and described fixedleg 32 is arranged in thefixed orifice 23.

Waterproof pad described in theutility model 3 fronts can also be provided withannular projection 31, and the quantity of describedannular projection 31 is one or more.In the present embodiment, describedwaterproof pad 3 fronts are provided with threeannular projections 31, lay respectively at inner ring, centre circle and the outer ring ofwaterproof pad 3.

Waterproof pad 3 reverse side described in the utility model also are provided withannular projection 31, and the quantity of describedannular projection 31 is one or more.In the present embodiment, describedwaterproof pad 3 reverse side are provided with twoannular projections 31, lay respectively at the inner ring and the outer ring ofwaterproof pad 3.

The height of describedwaterproof pad 3 tow sidesannular projections 31 adds the degree of depth of the thickness ofwaterproof pad 3 greater thangroove 21 itself.

The inner ring in describedwaterproof pad 3 fronts and the annular projection ofouter ring 31 leaves clearance position with the edge ofwaterproof pad 3, and the inner ring of the reverse side of describedwaterproof pad 3 and the annular projection ofouter ring 31 are all near the edge ofwaterproof pad 3.

Because the utility model LED display waterproof construction system is provided withwaterproof pad 3 between casing 1 anddemonstration module 2, show thegroove 21 that is provided with ccontaining waterproof pad on themodule 2, make and realize perfect seamless link between thedemonstration module 2 of LED display and the casing 1, compare the utility model LED display waterproof construction system with traditional mode, compact conformation, with low cost, only need showing waterproof pad of placement between module and the casing, waterproof pad has certain elasticity, can be full of the space between LED display casing and the module, waterproof effect is preferable.
