[0021] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0022] As Figures 1-3As shown, this embodiment of an adhesive backing structure with dustproof function includes an adhesive backing body 1. Four extension strips 10 are symmetrically arranged on both sides of the upper and lower ends of the adhesive backing body 1. Adhesive strips 11 are arranged on the outer walls of the extension strips 10. The design of the extension strips 10 and adhesive strips 11 ensures a tight connection between the two ends of the adhesive backing structure and the object. When external forces such as pulling or vibration are transmitted from both sides of the adhesive backing structure, it prevents the ends of the adhesive backing structure from warping upwards or the middle from arching, thus ensuring a stable connection between the adhesive backing structure and the object and effectively reducing the possibility of the adhesive backing structure detaching. Release paper 14 is installed on the outer wall of the adhesive strip 11 for easy protection. Sealing strips 5 are fixed around the adhesive backing body 1, and the outer walls of the sealing strips 5 are provided with a PVC coating 13. The design of the seal 5 effectively prevents moisture or dust from entering the adhesive body 1, ensuring the service life of the adhesive structure. The top of the adhesive body 1 is provided with an upper adhesive plate 2, and the bottom of the adhesive body 1 is provided with a lower adhesive plate 15. Release paper 12 is evenly distributed on the outer walls of the upper adhesive plate 2 and the lower adhesive plate 15. A reflective sheet 9 is installed on the upper end of the lower adhesive plate 15. The design of the reflective sheet 9 can provide adhesion for the adhesive body 1, allowing the adhesive body 1 to adhere to the surface of the material, effectively preventing the parts from moving or slipping. An ET film 8 is provided on the upper end of the reflective sheet 9. The design of the ET film 8 has moisture-proof and waterproof properties, which can effectively prevent moisture and other liquids from penetrating into the adhesive body 1, effectively extending the service life and protective effect of the adhesive body 1.

[0023] like Figures 1-3 As shown, in this embodiment, a flame-retardant plate 3 is arranged in the middle of the adhesive body 1, and a through hole 4 is opened on the flame-retardant plate 3. A mixing film 7 is connected to the top of the flame-retardant plate 3, and a face plate 6 is installed on the upper end of the mixing film 7. The design of the mixing film 7 can enhance the tensile strength, abrasion resistance and flexibility of the adhesive body, and help protect the integrity of the adhesive body 1. The design of the face plate 6 can make the adhesiveness of the adhesive body 1 stable and durable.

[0024] like Figures 1-3 As shown, in this embodiment, the flame-retardant board 3 is bonded to the adhesive backing body 1, the mixing film 7 is bonded to the flame-retardant board 3, the surface plate 6 is bonded to the mixing film 7 and the adhesive plate 2. The flame-retardant board 3 can achieve the flame-retardant effect of the flame-retardant adhesive strip 11. At the same time, the design of the through hole 4 facilitates the flow of heat generated by the two end components during use, ensuring that the heat of the adhesive backing body 1 is dissipated during use.

[0025] like Figures 1-3As shown, in this embodiment, the extension pull strip 10 is bonded with the back adhesive body 1, the adhesive strip 11 is bonded with the extension pull strip 10, the release paper two 14 is bonded with the adhesive strip 11, the design of the extension pull strip 10 can be extended to any shape, and the design of the adhesive strip 11 enables the extension pull strip 10 to be fixedly connected with each component, ensuring the stability of the back adhesive structure when fixing the components. The design of the release paper two 14 facilitates the protection of the adhesive strip 11, avoiding dust from sticking to the adhesive strip 11 when not in use.

[0026] As shown, Figures 1-3 in this embodiment, the seal 5 is bonded with the back adhesive body 1, and the PVC coating 13 is bonded with the seal 5. The seal 5 achieves a sealing effect around the back adhesive body 1, which can prevent dust and the like from entering each layer of the back adhesive body 1. In combination with the design of the PVC coating 13, the waterproofness of the back adhesive body 1 around can be achieved, effectively improving the service life of the back adhesive body 1.

[0027] As shown, Figures 1-3 in this embodiment, the upper adhesive plate 2 and the lower adhesive plate 15 are both bonded with the release paper one 12, and the reflective sheet 9 is bonded with the ET film 8. The design of the upper adhesive plate 2 and the lower adhesive plate 15 enables the two sides of the back adhesive body 1 to be respectively connected with two components.

[0028] The specific implementation process of this embodiment is as follows: when using the device, the appropriate size of the back adhesive body 1 is selected according to the size of the actually used mobile phone, notebook computer, and tablet computer components. The release paper one 12 on one side of the back adhesive body 1 is torn off, the upper adhesive plate 2 is fixed on one of the components, the release paper one 12 on the other side is torn off, the lower adhesive plate 15 is connected to the other component, the ET film 8 can solve the problem of difficult adhesion between different materials, then the positions of the extension pull strips 10 on both sides are adjusted according to the shape of the components, and the release film two is torn off to achieve the connection between the two ends of the back adhesive body 1 and the two components. The contact area between the components and the back adhesive body 1 is increased. When external forces such as pulling and vibration are applied to both sides of the back adhesive structure, the back adhesive structure is prevented from being warped at both ends or arched in the middle to form a concave surface, ensuring the stable connection between the back adhesive structure and the object, effectively reducing the occurrence of the back adhesive structure falling off. The design of the fireproof plate 3 in combination with the through hole 4 can effectively ensure the dissipation of heat on the contact surface when the two components are connected, and the design of the seal 5 and the PVC coating 13 can effectively achieve a sealing effect on the back adhesive body 1, effectively preventing dust from entering the inside of the back adhesive body 1.
