[0003] An existing modular assembled LCD display has the following disadvantages: currently, when installing a modular LCD display, most modules are snap-fitted to each other, which makes it difficult for installers to dismantle the assembled modules. During the dismantling process, the modules need to be pressed hard, which can easily damage the module display. In addition, it is difficult to waterproof and moisture-proof the module display, which makes the internal parts of the module display easy to be damaged. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a modular assembled LCD display screen which is highly practical, can be easily operated and has a relatively simple structure. The utility model solves the problem raised in the above background technology that, when installing modular LCD displays, most of them adopt a snap-in connection between modules, which makes it difficult for installers to remove the assembled modules. As a result, they need to push hard during the removal process, which can easily cause damage to the module display screen. In addition, it is difficult to waterproof and moisture-proof the module display screen, which makes the internal parts of the module display screen easy to be damaged.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a modular assembled liquid crystal display screen, including a main body, the front side of the main body is equidistantly provided with circular grooves, the inside of the circular groove is fixedly connected with a mounting spring, one end of the mounting spring is fixedly connected with a round block, the front side of the round block is fixedly connected with a suction cup, the adjacent part of the circular groove is provided with a power card slot, both sides of the round block are provided with card connection components, the back side of the main body is carded with a protective shell, the inside of the protective shell is fixedly connected with a moisture-proof plate, and the surface of the moisture-proof plate is provided with a waterproof pad.

[0006] Optionally, the clamping assembly includes holes on both sides of the outer surface of the round block, a telescopic spring is fixedly connected inside the hole, and one end of the telescopic spring is fixedly connected to the clamping block.

[0007] Optionally, two side walls inside the circular groove are provided with snap-fit ​​grooves, and the size of the snap-fit ​​grooves is adapted to the size of the snap-fit ​​block.

[0008] Optionally, the back side of the power card slot is electrically connected to a control group, and the control group is located inside the main body.

[0009] Optionally, an electronic screen block is adsorbed on the front side of the suction cup, and a plug-in block adapted to the battery card slot is provided on the back side of the electronic screen block.

[0010] Optionally, a shock-absorbing piston rod is sleeved inside the mounting spring, and an anti-oxidation coating is applied to the outer surface of the protective shell.

[0011] Optionally, heat dissipation blocks are provided on both sides of the main body, and dustproof nets are embedded on the surfaces of the heat dissipation blocks.

[0012] The utility model provides a modular assembled liquid crystal display screen, which has the following beneficial effects:

[0013] 1. The modular assembled LCD screen, through the arrangement of the round block, the card-connecting assembly and the suction cup, when the installer needs to assemble the electronic screen block, the plug-in block can be plugged into the power card-connecting slot, which adsorbs the back of the electronic screen block to the surface of the suction cup, and then presses the round block to compress its installation spring. When the round block enters the circular groove, the card-connecting block slides to the card-connecting slot position in accordance with the inner wall of the circular groove, and the telescopic spring drives the card-connecting block to automatically card into the card-connecting slot to fix the round block, thereby facilitating the staff to quickly assemble the electronic screen block.

[0014] 2. The modular assembled LCD display screen is provided with a protective shell, a main body and a moisture-proof plate. When the staff uses the main body, the main body is exposed to the air or outdoors for a long time, so that the moisture contained in the air and other factors continuously erode the interior of the main body. Then the moisture-proof plate and the protective shell effectively isolate the external erosion factors, thereby increasing the service life of the main body and avoiding the damage of the internal electronic components caused by the main body being affected by moisture.
