DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1-6As shown in the figure, the utility model provides a technical solution: a QLED screen protection device, including a QLED screen body 1. An installation plate 3 is fixedly connected to the outer surface of the QLED screen body 1. A guide groove 14 is opened on the outer surface of the installation plate 3. Two hinge rods 12 are fixedly connected inside the guide groove 14. A protective film 2 is rotatably connected between the two hinge rods 12. A torsion spring 13 is installed on the outer surfaces of the two hinge rods 12. Two clamping rods 8 are slidably connected to the outer surface of the installation plate 3, and the outer surface of the clamping rod 8 is clamped with the outer surface of the protective film 2; by pulling the protective film 2 with the installed handle 4, the torsion spring 13 will be under pressure during the pulling process. When the protective film 2 is pulled to a certain position, the clamping rod 8 slidably connected to the installation plate 3 will contact the protective film 2. When the clamping rod 8 slides into the clamping hole opened on the surface of the protective film 2, the installation of the protective film 2 can be completed, which can protect the QLED screen body 1, not only prevent the entry of dust and impurities, but also quickly install the protective film 2, and can ensure the subsequent protection effect of the QLED screen body 1.

[0024] Both ends of the two clamping rods 8 away from each other are fixedly connected with round plates 10, and a pull ring 11 is fixedly connected to the outer surface of the round plate 10. The provided pull ring 11 can provide a certain convenience for pulling the clamping rod 8, so as to facilitate the subsequent installation and disassembly of the protective film 2, and can ensure the subsequent use effect of the protective film 2.

[0025] Both outer surfaces of the two round plates 10 are fixedly connected with tension springs 9, and the other ends of the tension springs 9 are in contact with the outer surface of the installation plate 3. The provided round plates 10 can limit the tension springs 9 to a certain extent, so as to ensure the subsequent use effect of the tension springs 9.

[0026] A handle 4 is fixedly connected to the outer surface of the protective film 2, and a rubber sleeve is sleeved on the outer surface of the handle 4. The provided handle 4 can facilitate the subsequent collection and release of the protective film 2, and can ensure the subsequent use effect of the protective film 2. At the same time, the provided rubber sleeve can prevent detachment during the pulling process.
