Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a mobile LED display screen. Background Art

[0002] The LED display screen uses multiple lamp beads to form specific images, texts or videos, etc. In some environments such as hotels where instructions and announcements are required, the LED display screen is usually placed upright in a conspicuous position through a base to facilitate personnel to understand the relevant announcements or instructions.

[0003] However, when the existing LED display screen needs to be moved after being placed upright on the ground, it needs to be carried manually by personnel. When the display screen is large, the overall gravity is heavy, which makes it inconvenient to carry, making the movement of the LED display screen inconvenient. Therefore, we propose a mobile LED display screen to solve the above problem. Utility Model Content

[0011] The rubber pad can be squeezed against the ground to generate an adsorption force in the limiting hole, thereby further improving the stability of the rubber pad to the display screen body.

[0012] Preferably, a limit slider is arranged inside the sliding sleeve, a limit slot is arranged inside the display screen body, and the limit slider extends to the inside of the limit slot;

[0013] The sliding stability of the sliding sleeve can be improved, and the sliding sleeve can be prevented from shaking and tilting.

[0014] Preferably, a fixed shaft rod is arranged inside the limit slot, and the limit slider is sleeved on the outside of the fixed shaft rod;

[0015] The sliding stability of the sliding sleeve is further improved.

[0016] Preferably, a support spring is sleeved on the outside of the fixed shaft rod, the support spring is located above the limit slider, one end of the support spring is fixedly connected to the limit slider, and the other end of the support spring is fixedly connected to the top of the inner wall of the limit slot;

[0017] The support spring can support the limit slider, so that the limit slider drives the sliding sleeve to descend, and the sliding sleeve drives the rubber pad to be squeezed with the ground through the connecting rod, so that the display screen body is more stable when placed, and when it needs to be moved, the sliding sleeve can be pulled to complete the movement of the rubber pad off the ground.

[0018] Preferably, both sides of the sliding sleeve are provided with connecting rods, and both sides of the display screen body are provided with connecting slots, and the connecting rods and the connecting slots are adapted to each other;

[0019] The personnel can hold the connecting rod and drive the sliding sleeve to rise, so that the sliding sleeve can be pulled to drive the rubber pad off the ground and the connecting rod can be embedded in the connecting slot to complete the positioning of the sliding sleeve. When the display screen body is moved to the specified position, the connecting rods on both sides can be pulled to complete the stable placement, and the operation is simple.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model pulls the connecting rod, so that the connecting rod drives the sliding sleeve to rise, and then the sliding sleeve drives the rubber pad to rise away from the ground through the connecting rod. At this time, the connecting rod is embedded in the inside of the connecting slot to position the sliding sleeve, so that the display screen body can be moved by the supporting wheels, and then a single person can push and move it, saving manpower and making the movement of the display screen body more convenient.

[0022] 2. After the display screen body of the utility model moves to the specified position, the connecting rods on both sides are pulled, so that the support spring drives the limit slider to descend, and the limit slider drives the sliding sleeve to descend, so that the rubber pad squeezes the ground, so that the limit hole is deformed and adsorbed on the ground, thereby limiting the display screen body, making the display screen body more stably placed and will not move.
