[0045] The utility model provides a replaceable film sticking component.

[0046] In the embodiment of the present utility model, please refer to Figure 1 and Figure 4 , the replaceable film assembly includes:

[0047] The inner support 100 has a limiting groove 110 formed in the middle thereof, and two opposite side walls of the limiting groove 110 are provided with avoidance openings 140; and

[0048] The film 200 is adaptively arranged in the limiting groove 110. The film 200 includes a film body 210, a first release film 220 and a second release film 230. The first release film 220 and the second release film 230 are respectively attached to opposite sides of the film body 210.

[0049] The opposite ends of the first release film 220 extend outward from the film body 210 to the avoidance opening 140 and are bonded to the inner support 100. The second release film 230 includes a protective layer 231 and a drawstring 232. The protective layer 231 is attached to the surface of the film body 210. The drawstring 232 is connected to the protective layer 231 adjacent to one avoidance opening 140 and extends toward the other avoidance opening 140 to the outside of the limiting groove 110. The limiting groove 110 is used for the device 400 to be applied to be adapted and placed.

[0050] The technical solution of the utility model is to set a limiting groove 110 in the middle of the inner support 100, and open a relative avoidance opening 140 on the side wall of the limiting groove 110, and the film 200 is installed in the limiting groove 110, wherein the end of the first release film 220 on the film 200 is extended out from the film body 210 and bonded to the bottom of the avoidance opening 140, so that the film 200 can be stably installed in the limiting groove 110, and the second release film 230 on the film 200 is attached to the side of the film body 210 away from the first release film 220, the drawstring 232 is connected to the protective layer 231 at a position close to one avoidance opening 140, and extends toward the other avoidance opening 140, and is penetrated through the avoidance opening 140 and protrudes out of the limiting groove 1 10, when it is necessary to attach the film body 210 to the device 400 to be attached, the device 400 to be attached is placed in the limiting groove 110. Under the limiting effect of the limiting groove 110, the device 400 to be attached and the film body 210 are accurately opposite to each other. Then, the drawstring 232 is pulled. Under the traction of the drawstring 232, the protective layer 231 gradually separates from the film body 210 at the end connected to the drawstring 232, and the film body 210 is synchronously attached to the device 400 to be attached. After the protective layer 231 completely escapes from the limiting groove 110, the film body 210 is also completely attached to the device 400 to be attached. In this process, the protective layer 231 and the drawstring 232 rub against the screen of the device 400 to be attached to generate static electricity, thereby achieving the effect of cleaning the screen. Thus, through the above method, the user only needs to place the device to be applied 400 in the limiting groove 110, and pull the pull strap 232 to apply the film body 210 to the screen of the device to be applied 400, which simplifies the application operation and improves the application efficiency and operating convenience.

[0051] It should be noted that the device 400 to be applied can be an electronic device such as a mobile phone, a computer, a tablet, or other components that need to be applied with a protective film. In the process of applying the film 200, the film assembly needs to be clamped in the clamp 300. The material of the clamp 300 is relatively strong compared to the material of the film assembly, which can effectively ensure the stability of the device 400 to be applied in the limit groove 110, and make the device 400 to be applied and the film 200 have an interaction force. After the pull belt 232 pulls out the protective layer 231, the film body 210 is stably applied to the screen of the device 400 to be applied. In this way, the film assembly can be set according to the specifications and sizes of the device 400 to be applied. By replacing the film assembly on the clamp 300 to adapt to the current device 400 to be applied, the film 200 can be applied to devices 400 of various specifications and sizes. It not only ensures the flexibility of applying the film 200, but also reduces the production cost of the film 200 tool.

[0052] Without loss of generality, please refer to Figure 1 and Figure 4The end of the first release film 220 is configured as a bonding end 221, and the bottom wall of the avoidance opening 140 is provided with a bonding portion 141. The bonding end 221 is protruded toward the avoidance opening 140 from the film body 210, and then bonded to the corresponding bonding portion 141, so that the film 200 can be stably placed in the limiting groove 110, which is convenient for users to use. Similarly, the protective layer 231 and the drawstring 232 of the second release film 230 can be integrally formed and folded and connected to each other near the avoidance opening, or they can be separately formed and then connected to each other, and the width of the drawstring 232 is smaller than the width of the protective layer 231. Among them, the height, width and length referred to in this scheme are all based on the membrane body 210, and the thickness in this embodiment is equivalent to the direction of the height. Moreover, the direction descriptions such as top, bottom, bottom and top referred to in this scheme are all based on the opening direction of the limiting groove 110. The opening direction close to the limiting groove 110 is the top and the top, and the opening direction away from the limiting groove 110 is the bottom and the bottom.

[0053] In one embodiment, please refer to Figure 2 The avoidance opening 140 can be formed by disconnecting the groove wall of the limiting groove 110, or by opening a through hole in the groove wall of the limiting groove 110. When the avoidance opening 140 is configured as a through hole, the second release film 230 is opposite to the avoidance opening 140 in the length direction, so that in the process of pulling the drawstring 232, the protective layer 231 can be stably separated from the film body 210 to avoid interference with the application of the film body 210 to the device 400 to be applied. In addition, the side wall of the limiting groove 110 has a portion opposite to the film body 210 at the avoidance opening 140, so that in the process of pulling the drawstring 232, the film body 210 can be stably limited in the limiting groove 110, effectively ensuring the stability of the film body 210 in the limiting groove 110.

[0054] In one embodiment, please refer to Figure 1 and Figure 4, the film 200 is arranged adjacent to the bottom wall of the limiting groove 110, and the second release film 230 is attached to the side of the film body 210 facing the notch of the limiting groove 110. It can be understood that the film 200 is arranged on the bottom wall of the limiting groove 110, and the space between the film 200 and the notch of the limiting groove 110 is for the device 400 to be attached, and the device 400 to be attached needs to be attached to the side of the film body 210 facing the film 200. In the process of attaching the film 200, it is only necessary to press the device 400 to be attached toward the film 200. Under the cooperation of the bottom wall and the side wall of the limiting groove 110, the limiting groove 110 can ensure that the device 400 to be attached and the film 200 are stable and accurately relative to each other, and avoid the process of pulling the pull belt 232 to interfere with the positional relationship between the screen and the film body 210, thereby improving the convenience of operation during the attachment process. In other embodiments, the film 200 can also be arranged adjacent to the notch of the limiting groove 110 and kept stable at the notch of the limiting groove 110. At the same time, a placement opening is opened on the side wall of the limiting groove 110. The application device 400 is placed in the limiting groove 110 from the placement opening, and the screen is placed opposite to the second release film 230. The film 200 is pressed to make the film body 210 abut against the screen, and the film body 210 can be applied to the screen by pulling the drawstring 232.

[0055] Further, in this embodiment, please refer to Figure 2 and Figure 3 , the inner peripheral wall of the limiting groove 110 is provided with a first convex portion 120, and the first convex portion 120 is used to hold the film 200, and there is a gap between the film 200 and the bottom wall of the limiting groove 110. It can be understood that the first convex portion 120 has a step surface facing the notch of the limiting groove 110, and the film 200 can abut against the step surface of the first convex portion 120, which not only forms a bottom-up support for the film 200, but also ensures the stability of the film 200 in the limiting groove 110, or there can be a gap between the first convex portion 120, and the connection relationship between the first release film 220 and the inner support 100 is used to ensure the stability of the film 200 in the limiting groove 110, but at least it is ensured that during the process of applying the film 200, the step surface of the first convex portion 120 abuts against the film 200 to form a support for the film 200, thereby ensuring that the film body 210 can be stably applied to the device 400 to be applied. In addition, there is a gap between the film 200 and the bottom wall of the limiting groove 110. During the process of applying the film 200, the film 200 is applied to the device 400 to be applied by applying a thrust force on the lower side of the film 200, so as to avoid the unevenness of the bottom wall of the limiting groove 110 due to process errors affecting the application effect of the film 200. In other embodiments, the film 200 may also directly abut against the bottom wall of the limiting groove 110 to support the film 200.

[0056] Further, in this embodiment, please refer to Figure 2and Figure 3 The inner peripheral wall of the limiting groove 110 is provided with a second convex portion 130, which is arranged closer to the notch of the limiting groove 110 than the first convex portion 120. The protrusion height of the first convex portion 120 is greater than the protrusion height of the second convex portion 130. The second convex portion 130 is used to hold the device 400 to be applied and to limit the film 200 in the circumferential direction of the limiting groove 110. It can be understood that the second convex portion 130 has a step surface facing the notch of the limiting groove 110. During the film 200 application process, the device 400 to be applied can be abutted against the step surface of the second convex portion 130. The second convex portion 130 not only supports the device 400 to be applied, but also ensures the stability of the device 400 to be applied in the limiting groove 110. It should be noted that the protrusion height of the first protrusion 120 and the protrusion height of the second protrusion 130 are expressed as the distance protruding from the inner wall of the limiting groove 110 toward the center thereof. In this way, the first protrusion 120 and the second protrusion 130 both have step surfaces facing the notch of the limiting groove 110, so as to avoid the second protrusion 130 interfering with the first protrusion 120 and failing to apply the film body 210 to the device to be applied 400. In addition, the film 200 abuts against the second protrusion 130 in the circumferential direction of the limiting groove 110, that is, the second protrusion 130 also plays a guiding and positioning role in the placement of the film 200, so as to facilitate the placement of the film 200 in the limiting groove 110. Similarly, the bottom wall of the limiting groove 110 also plays a guiding and positioning role in the placement of the device to be applied 400, so as to facilitate the placement of the device to be applied 400 in the limiting groove 110 and ensure the accuracy of applying the film 200. Of course, in other embodiments, the limiting groove 110 may not be provided with the second protrusion 130 , and during the process of applying the film 200 , the device to be applied 400 is directly attached to the film 200 .

[0057] Specifically, in this embodiment, please refer to Figure 3 and Figure 4, define the difference in spacing between the first convex portion 120 and the second convex portion 130 and the notch of the limiting groove 110 as D, define the thickness of the film 200 as H, and D and H satisfy: D≤H. It can be understood that in the opening direction of the limiting groove 110, the difference between the spacing between the first convex portion 120 and the notch of the limiting groove 110 and the spacing between the second convex portion 130 and the notch of the limiting groove 110 is D, and the thickness direction of the film 200 is parallel to the opening direction of the limiting groove 110. In this way, after the film 200 is placed in the limiting groove 110, the second release film 230 is arranged closer to the notch of the limiting groove 110 than the second convex portion 130. During the process of attaching the film 200, the device 400 to be attached can be in contact with the film 200, thereby avoiding the second convex portion 130 causing a spacing between the film 200 and the device 400 to be attached, thereby ensuring the convenience and reliability of attaching the film 200. Of course, in other embodiments, a push piece may also be provided on the bottom wall of the limiting groove 110. During the process of applying the film 200, the push piece pushes the film 200 toward the groove opening of the limiting groove 110 so that the film 200 can be stably abutted against the device 400 to be applied.

[0058] Further, in this embodiment, please refer to Figure 2 and Figure 3, there are multiple first convex parts 120 and second convex parts 130, and they correspond one to one. The second convex parts 130 are connected to the top of the corresponding first convex parts 120, and the first convex parts 120 are located at the connection between the groove side wall and the groove bottom wall of the limiting groove 110. It can be understood that the multiple first convex parts 120 and the multiple second convex parts 130 are arranged one to one, and the first convex parts 120 are connected to the corresponding second convex parts 130, that is, in the opening direction of the limiting groove 110, the first convex parts 120 and the corresponding second convex parts 130 are integrated, and each has a step surface to respectively support the film 200 and the device 400 to be applied. Furthermore, the first convex portion 120 is arranged closer to the bottom wall of the limiting groove 110 than the second convex portion 130, and is located at the connection between the bottom wall and the side wall of the limiting groove 110. In this way, the center of gravity of the film assembly is reduced during the process of applying the film 200, making the operation of applying the film 200 more stable, while also ensuring that there is a gap between the film 200 and the bottom wall of the limiting groove 110, thereby ensuring the application effect of the film 200 on the device to be applied. In addition, the first convex portion 120 and the second convex portion 130 are arranged at the inner corner of the limiting groove 110, which can effectively ensure the stability of the film 200 and the device 400 to be applied in the limiting groove 110, so that the film 200 and the device 400 to be applied are parallel to each other, thereby ensuring the application effect of the film 200. Similarly, the first convex portion 120 and the second convex portion 130 can also be arranged in the middle of the inner wall of the limiting groove 110 in the length direction, so as to ensure the support stability of the first convex portion 120 and the second convex portion 130 for the film 200 and the device to be applied 400 respectively. Of course, in other embodiments, at least one of the first convex portion 120 and the second convex portion 130 can also be continuously arranged along the inner peripheral wall of the limiting groove 110.

[0059] In one embodiment, please refer to Figure 2 , a clearance opening 150 is provided on the bottom wall of the limiting groove 110. It should be noted that a flexible pad 191 is provided at the bottom of the inner support 100 corresponding to the clamping member 300. In the process of applying the film 200, the flexible pad 191 is passed through the clearance opening 150 and protrudes out of the limiting groove 110 to push the film 200 toward the groove opening of the limiting groove 110, thereby causing the film body 210 to be stably attached to the device 400 to be applied. At the same time, the air between the film body 210 and the device 400 to be applied is also expelled to ensure the effect of applying the film 200. Without loss of generality, the elastic expansion direction of the flexible pad 191 is the distribution direction of the film 200 and the device 400 to be applied. Of course, in other embodiments, the clearance opening 150 may not be provided on the bottom wall of the limiting groove 110, and the flexible pad 191 may be directly set on the bottom wall of the limiting groove 110.

[0060] Further, in this embodiment, please refer to Figure 2 and Figure 4, the clearance opening 150 is located in the middle of the limiting groove 110 and extends along the length direction of the film body 210. In this way, the flexible pad 191 is located in the middle of the screen of the device 400 to be applied and extends toward the edge. During the application of the film 200, the flexible pad 191 can apply force from the middle of the film body 210, and better drive the bubbles between the film body 210 and the device 400 to be applied to the periphery to avoid bubbles between the film body 210 and the device 400 to be applied, thereby ensuring the application effect of the film 200. Of course, in other embodiments, the clearance opening 150 can also be set in multiples, and its protruding height gradually decreases from the middle of the film body 210 to the periphery.

[0061] In one embodiment, please refer to Figure 5 , the inner support 100 also includes a bottom plate 190, on which a flexible pad 191 is provided. The bottom plate 190 is arranged at the bottom of the inner support 100, and the flexible pad 191 is penetrated through the opening 150 and abuts against the film 200. In this way, the film assembly integrates the flexible pad 191, the film 200 abuts against the flexible pad 191, and pushes the film 200 toward the notch of the limiting groove 110, so that the film 200 can effectively abut against the device 400 to be applied. At the same time, in the process of applying the film 200, the bubbles between the film body 210 and the device 400 to be applied are discharged to ensure the application effect of the film 200.
