[0002] With the rapid development of science and technology, LED display technology has become one of the most widely used display technologies today. It is widely welcomed for its high efficiency, energy saving, bright colors and long life. At the same time, for many application fields, especially for display needs in outdoor or underwater environments, waterproof performance has become an indispensable and important indicator. Therefore, it is particularly important to develop a screen that combines LED display technology with waterproof performance.

[0003] When installing traditional waterproof LED display screens, most of them are directly laid flat and then glue is poured into the gaps. However, the screen may shift when the glue is not dry, which may easily cause gaps and reduce the waterproof performance during use.

[0004] Therefore, those skilled in the art have proposed a portable waterproof LED display screen to solve the problems raised by the background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a portable waterproof LED display screen to solve the problems in the prior art that the screen may still be offset when the glue is not dry, which may easily lead to gaps and the waterproofness may be reduced during use.

[0006] A portable waterproof LED display screen comprises a back integrated cast rubber bottom shell, an outer side wall of the back integrated cast rubber bottom shell is installed with a middle layer PCB board, and a lamp bead is installed at one end of the middle layer PCB board away from the back integrated cast rubber bottom shell;

[0007] A splicing mechanism is arranged between the back integrally cast rubber bottom shells.

[0008] Preferably, the splicing mechanism includes a connecting slide groove, the connecting slide groove is arranged at the top of the back integral cast rubber bottom shell, the top of the back integral cast rubber bottom shell is arranged with a limiting groove, and the outer side wall of the back integral cast rubber bottom shell is arranged with a limiting guide groove.

[0009] Preferably, the inner side wall of the connecting slide groove is slidably connected to a limiting block, and the top end of the limiting block is fixedly connected to a fixed top plate.

[0010] Preferably, the inner side wall of the fixed top plate is threadedly connected with a through screw, and the top end of the fixed top plate is threadedly connected with two limit screws.

[0011] Preferably, the two limiting screws are threadedly connected to the limiting grooves, and the inner side wall of the top end of the back integral cast rubber bottom shell is fixedly connected to a limiting stopper.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can control the distance between the display screens before pouring glue by setting the splicing mechanism, and can also prevent the display screens from shifting when pouring glue, and avoid certain gaps caused by the movement of the display screens.

[0018] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0019] As attached Figure 1 To Attachment Figure 3 As shown:

[0020] Embodiment 1: The utility model provides a portable waterproof LED display screen, comprising a back integrated cast bottom shell 1, an outer side wall of the back integrated cast bottom shell 1 is installed with a middle layer PCB board 11, and a lamp bead 12 is installed at one end of the middle layer PCB board 11 away from the back integrated cast bottom shell 1;

[0021] A splicing mechanism, wherein the splicing mechanism is arranged between the back integrated cast bottom shell 1, and the splicing mechanism includes a connecting slide 2, wherein the connecting slide 2 is opened at the top of the back integrated cast bottom shell 1, and a limiting groove 21 is opened at the top of the back integrated cast bottom shell 1, and a limiting guide groove 22 is opened on the outer wall of the back integrated cast bottom shell 1, and the inner side wall of the connecting slide 2 is slidably connected to a limiting block 23, and the top of the limiting block 23 is fixedly connected with a fixed top plate 24, and the inner side wall of the fixed top plate 24 is threadedly connected with a through screw 25, and the top of the fixed top plate 24 is threadedly connected with two limiting screws 26, and the two limiting screws 26 are threadedly connected to the limiting groove 21, and the inner side wall of the top of the back integrated cast bottom shell 1 is fixedly connected with a limiting stopper 27.

[0022] As can be seen from the above, when the display screen needs to be spliced, first place the two back integrated cast rubber bottom shells 1 together, then penetrate into the two connecting slide grooves 2 through the limiting block 23, then connect the two connecting slide grooves 2 tightly together, and then install the upper limit screw 26, so that the limiting screw 26 is connected to the limiting groove 21, which plays a role in limiting the back integrated cast rubber bottom shell 1, and then penetrate the middle through the through screw 25, so that the through screw 25 is connected to the fixed top plate 24 installed at the bottom, and the upper and lower ends of the back integrated cast rubber bottom shell 1 are limited.
