[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 One embodiment provided by this utility model: A PE protective film structure is disclosed. The protective film body 1, central soft rubber 2, reinforcing soft rubber 4 and connecting strip 14 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here. The structure includes a protective film body 1, a fastening component installed inside the protective film body 1, a connecting component installed on the upper surface of the protective film body 1, and a reinforcing component provided on both the front and rear surfaces of the protective film body 1. The structure of the protective film body 1 is the same as that in the prior art. The fastening assembly includes a central soft rubber 2, which is installed inside the protective film body 1. A first transparent film 3 is installed at the lower end of the central soft rubber 2. A reinforcing soft rubber 4 is installed inside the protective film body 1. The reinforcing soft rubber 4 is I-shaped, which can enhance the overall adhesive connection effect. The connecting component includes a fiber layer 5, which is installed on the upper surface of the protective film body 1. When the protective film body 1 is attached to the workpiece, the central soft rubber 2 is aligned with the midpoint to be attached. After alignment, the first transparent film 3 is peeled off from the lower end of the central soft rubber 2, thus allowing the protective film to be firmly attached to the workpiece from the middle. Subsequently, the reinforcing soft rubber 4 is also attached to the upper surface of the workpiece. The reinforcing soft rubber 4 has an I-shaped structure, making the overall attachment relatively stable.

[0019] An elastic strip 6 is installed on the top surface of the fiber layer 5, and a wear-resistant layer 7 is provided on the upper surface of the elastic strip 6. A PE film body 8 is installed on the top surface of the wear-resistant layer 7, and an oil- and water-resistant layer 9 is installed on the upper surface of the PE film body 8. The fiber layer 5 and the wear-resistant layer 7 are connected by the elastic strip 6. After the protective film body 1 is laminated, the PE film body 8 and the oil- and water-resistant layer 9 are pressed together. At this time, the wear-resistant layer 7 and the elastic strip 6 also apply pressure to the protective film body 1. Since there is a gap between the fiber layer 5 and the wear-resistant layer 7, a certain force is applied during pressing, allowing the protective film body 1 to adhere more stably to the workpiece. Therefore, this design, through the cooperation of the fastening and connecting components, not only ensures that the protective film body 1 is precisely and stably laminated to the workpiece, avoiding air bubbles, but also provides strong pressure during lamination to ensure a tight bond, thereby enhancing the overall lamination effect.

[0020] The reinforcing component includes an adhesive pad 10, which is installed on the front and rear surfaces of the protective film body 1. A second transparent film 11 is provided at the lower end of the adhesive pad 10, and the second transparent film 11 and the adhesive pad 10 have a tear-off structure. Connecting strips 14 are installed on the front and rear surfaces of the PE film body 8, and mounting pads 13 are installed inside the connecting strips 14. Rubber strips 12 are installed at the lower end of the mounting pads 13, and two sets of rubber strips 12 are provided. When the protective film body 1 is applied, the second transparent film 11 is peeled off from the lower surface of the bonding pad 10, so that the lower surface of the bonding pad 10 is attached to the workpiece. Then, by pressing the mounting pad 13, which is elastic, the mounting pad 13 can press the rubber strip 12 downward, making the bonding pad 10 adhere more firmly to the surface of the workpiece. After pressing, the mounting pad 13 will move upward, so that the front and rear ends of the protective film body 1 will not lift up through the two sets of bonding pads 10. Therefore, this setting, through the connecting component, not only prevents the front and rear surfaces of the protective film body 1 from lifting up, but also makes it convenient to peel off the protective film body 1 later.

[0021] Working principle: When using the protective film body 1, align the central soft rubber 2 with the midpoint to be bonded, and then peel off the first transparent film 3 from the bottom of the central soft rubber 2. This allows the protective film to be bonded and secured to the workpiece from the middle. Subsequently, the reinforcing soft rubber 4 is also bonded to the upper surface of the workpiece. The reinforcing soft rubber 4 has an I-shaped structure, which makes the overall bonding relatively stable. At the same time, the fiber layer 5 and the wear-resistant layer 7 are connected by the elastic strip 6. After the protective film body 1 is bonded, press the PE film body 8 and the oil and water resistant layer 9. At this time, the wear-resistant layer 7 and the elastic strip 6 can also apply pressure to the protective film body 1. There is a gap between the fiber layer 5 and the wear-resistant layer 7, so there is a certain force when pressing. Therefore, the protective film body 1 can be bonded to the workpiece more stably. After the protective film body 1 is applied, the second transparent film 11 is peeled off from the lower surface of the bonding pad 10, so that the lower surface of the bonding pad 10 is attached to the workpiece. Then, by pressing the mounting pad 13, which is elastic, the mounting pad 13 can press the rubber strip 12 downward, making the bonding pad 10 adhere more firmly to the surface of the workpiece. After pressing, the mounting pad 13 will move upward, so that the front and rear ends of the protective film body 1 will not lift up through the two sets of bonding pads 10. The above is the working principle of this utility model.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
