Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

Referring to fig. 1, an LED display screen with a waterproof structure includes a box 1 and a cover plate 2, which are matched with each other, and the LED display screen is arranged in the box 1. The one side that is used for of box 1 and apron 2 complex is the terminal surface of box 2 promptly, is provided with on the terminal surface of box 1 and supports the pressure tank 101, is provided with grafting lug 201 on the terminal surface of apron 2, and grafting lug 201 is fixed in and supports in the pressure tank 101. The box body 1 and the cover plate 2 are fixedly connected with the abutting-against groove 101 through the inserting convex block 201. The plugging convex block 201 can be a cylindrical pin welded on the cover plate 2, or a plate welded on the cover plate, and the abutting groove is correspondingly provided with a unthreaded hole, a rectangular groove or a waist-shaped groove.

All articulated on apron 1 upper wall, the lower wall have L shape waterproof board 3, and two waterproof board 3 symmetries set up. All offer the mounting groove that is used for fixed waterproof board 3 on the roof of box 1, the lower wall, two mounting grooves also symmetry set up. The waterproof board 3 may be provided with a buckle 301 except for one side hinged with the cover board 2. As shown in fig. 1, it is preferable that a snap 301 is provided on the left side wall of the waterproof sheet 3. Correspondingly, the mounting groove is close to the end face setting of the box body 1, and a groove 103 is formed in the groove inner side wall, far away from the end face of the box body 1, of the mounting groove.

The bottom wall of the groove is further provided with a locking hole 105, the locking hole 105 is a countersunk hole, the locking hole 105 is in threaded connection with a screw 106, and the screw 106 abuts against the insertion convex block 201 so as to fix the insertion convex block 201 in the abutting groove 101.

During assembly, the box body 1 and the cover plate 2 are opposite, and then the inserting convex block 201 is inserted into the abutting-pressing groove 101. The screw 106 is then screwed into the capture hole 105 until the screw 106 locks the bayonet lug 201. At this time, the case 1 and the cover 2 are integrated. Then place waterproof bed course 4 in the mounting groove, articulate the waterproof board 3 upset of apron 2 for buckle 301 on the waterproof board 3 is buckled in recess 103, thereby dies waterproof board 3 lock. The waterproof board 3 extrudes the waterproof cushion 4 so that the waterproof cushion 4 is paved on the top surface of the mounting groove.

Since the length of the waterproof board 3 is longer than that of the installation groove, the waterproof board 3 of the embodiment necessarily closes the gap between the cover plate 2 and the box body 1, and prevents water from flowing into the box body 1 from the gap between the two.

Compared with the prior art in which water can be partially immersed into the box body 1 from the screws, the drain groove 104 is provided on the groove bottom wall of the mounting groove. Even if a part of the water flows into the installation groove from the gap between the waterproof sheet 3 and the groove, it is accumulated in the drain groove 104. Thereby preventing water from being introduced into the case body 1 through the capture hole in the mounting groove or causing rusting of the screw.

Compare in prior art, the three-layer waterproof construction that has in this embodiment, the first layer is that waterproof board 3 shelters from the gap between apron 2 and the box 1, and the second floor is that waterproof bedding layer 4 fills up the clearance between waterproof board 3, mounting groove and the apron 2, further blocks during water immerses box 1, and the third layer is the sluicing groove.

The waterproof pad layer 4 in this embodiment is mainly made of rubber plastic waterproof material, including but not limited to rubber gasket or profiled rubber gasket.

Example 2

On the basis of embodiment 1, the drainage groove 104 is a trapezoidal groove, and preferably, one side wall of the trapezoidal groove close to the groove 103 is a plumb surface, and one side wall close to the lock hole is an inclined surface. The flashing 3 is L-shaped and after the flashing 3 has been mounted in place, a space, i.e. a gutter, must necessarily exist between the flashing 3 and the gutter 104. The drain groove 104 can guide the water vapor immersed in the mounting groove 103 to the drain groove 104, thereby reducing the influence of the water vapor on the service life of the waterproof cushion layer 4.

Example 3

In example 1, the cross section of the bottom wall of the drain groove 104 is triangular. In order to facilitate water accumulation of the water drainage groove 104, the water drainage groove 104 is arranged to be in a pointed shape consisting of two slope surfaces, so that accumulated water is facilitated to move towards two sides of the box body 1, and electrical elements on two sides of the box body 1 are fewer.

Example 4

On the basis of embodiment 1, in order to further avoid the external rainwater to soak, still be provided with L type slot 107 on the terminal surface of box 1, seted up holding tank 202 on the apron 2, holding tank 202 and external intercommunication, slot 107 adorns in holding tank 202. By guiding the permeated water into the grooves 107, electronic components such as an LED screen in the case 1 are protected. And the cross section of the bottom wall of the groove 107 is triangular, namely, the bottom wall is in a pointed shape, so that the water can be conveniently accumulated, the accumulated water can be conveniently accumulated to the two sides of the box body 1, and the water can be prevented from being accumulated in the middle of the box body 1.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
