Description of the embodiments
The invention will be described in further detail below with reference to the drawings by means of specific embodiments.
Taking the protection of an LED display module as an example, as shown in fig. 1 and 2, the anti-collision protection device of the invention comprises a protection sheet (1), a rotatable structure (2), a fixed shaft (3) and a spring (4). The fixed shaft (3) is arranged inside the box body (6) and is used for fixing the device. One end of the rotatable structure (2) rotates around the fixed shaft (3), the other end of the rotatable structure is connected with the protection sheet (1), a spring (4) is sleeved on the fixed shaft (3), and the spring (4) is used for providing elasticity to tightly attach the protection sheet (1) to the outer side edge of the box body (6). The height of the protective sheet (1) exceeds the height of the parts to be protected.
The protection device has a telescopic protection structure, and when the LED display module is in an independent single box state, the protection sheet of the protection device is attached to the outer side edge of the metal frame of the LED box body, so that the LED lamp beads (8) can be protected. Therefore, even if collision occurs in the transportation or assembly process, the protection sheet is only impacted, and the LED display device cannot be directly damaged.
