Abstract
Description
Technical Field
[0001] This utility model relates to the field of film applicators, and in particular to a roller-type film applicator. Background Technology
[0002] Electronic devices have become indispensable communication tools in people's lives. However, due to frequent use, the screens of electronic devices are prone to getting dirty or even scratched. Generally, screen protectors are used to protect the screens of electronic devices. However, when applying screen protectors, most people rely on the operator's experience to judge whether the screen protector is applied evenly and whether it completely covers the screen. This operation can easily result in the screen protector being applied crookedly, requiring multiple adjustments, or producing many air bubbles that cannot be completely eliminated, causing considerable trouble for the operator.
[0003] To address this issue, manufacturers have developed a screen protector applicator. The operator first places the phone in the receiving slot, ensuring the screen is exposed, then peels off the release liner from the surface of the screen protector. Next, the screen protector is initially applied to the screen. Because the screen protector and release liner form an angle, a roller is used to press along the direction of the screen protector's extension to properly adhere it. However, this design has a significant drawback: after the roller has pressed down, it needs to be moved in the opposite direction to return to its original position before the phone can be removed. However, this reverse movement applies a backward force to the screen protector, causing it to wrinkle. Therefore, improvements to the existing screen protector applicator are necessary. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a roller-type screen protector applicator, which can effectively solve the problem that after the existing screen protector applicator has applied the screen protector to the mobile phone, it needs to move in the opposite direction to reset the roller. During the reverse movement of the roller, a backward force is applied to the screen protector, which makes the screen protector prone to wrinkling.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A roller-type screen protector applicator includes a screen protector body and a roller assembly; the screen protector body has a receiving groove for placing a mobile phone, and guide rails are provided on both sides of the receiving groove, the guide rails extending along the direction of screen protector application; the roller assembly can slide back and forth along the extension direction of the guide rails and can be detachably mounted on the guide rails.
[0007] As a preferred embodiment, the roller assembly includes a bracket and a roller body. The bracket is slidable back and forth along the extension direction of the guide rail and is detachably mounted on the guide rail. The roller body is mounted on the bracket and moves with the back and forth sliding of the bracket.
[0008] As a preferred embodiment, the bracket is provided with a guide groove, and when the bracket slides on the guide rail, the guide rail enters the guide groove.
[0009] As a preferred embodiment, the front end of the film body is provided with a shaft portion, and the bracket is provided with a hinge portion, which is detachably hinged to the shaft portion.
[0010] As a preferred embodiment, the periphery of the hinge portion is provided with a hinge groove, which is hinged together with the shaft portion in a detachable manner.
[0011] As a preferred embodiment, the bracket is provided with a first limiting part, and the guide rail extends outward to form a second limiting part. Both ends of the second limiting part are provided with notches that are adapted to the first limiting part.
[0012] As a preferred embodiment, the film body has a receiving portion located in front of the receiving groove, and the aforementioned roller body is located above the receiving portion.
[0013] As a preferred embodiment, the rear end of the film-applying body is provided with a through groove, which is located behind the receiving groove. The through groove allows the release paper to pass through, preventing the release paper from being completely separated from the film to be rolled during the film-applying process due to interference, thereby affecting the film-applying effect.
[0014] As a preferred embodiment, the inner wall of the receiving groove extends inward with protruding ribs.
[0015] As a preferred embodiment, the bottom surface of the receiving groove is provided with a clearance hole.
[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0017] By detachably mounting the roller assembly on the guide rail, and allowing the roller assembly to slide back and forth along the extension direction of the guide rail, the phone screen and the screen protector can be perfectly adhered after the roller assembly rolls once along the extension direction of the guide rail. At this point, the roller assembly can be detached from the guide rail and reinstalled without sliding in the opposite direction, thus avoiding secondary rolling of the screen protector and preventing backward force from being applied, effectively preventing wrinkles after the screen protector is applied.

[0034] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a film-applying body 10 and a roller assembly 20.
[0035] The screen protector body 10 has a receiving groove 11 for placing a mobile phone. Guide rails 12 are provided on both sides of the receiving groove 11, extending along the direction of the screen protector application. In this embodiment, a shaft portion 13 is provided at the front end of the screen protector body 10, and a receiving portion 14 is provided on the screen protector body 10, located in front of the receiving groove 11. Furthermore, a through groove 15 is provided at the rear end of the screen protector body 10, located behind the receiving groove 11. The through groove 15 allows release paper to pass through, preventing it from slipping during the screen protector application process. Because the release paper is interfered with, it does not completely detach from the film to be rolled during the application of the film, thus affecting the film application effect; and, the inner wall of the receiving groove 11 extends inward with a rib 111. This design allows the mobile phone to be fixed in the receiving groove 11, preventing the mobile phone from shifting position during the application of the film, and also makes the opening of the receiving groove 11 larger than the size of the mobile phone, making it easier to insert the mobile phone; the bottom surface of the receiving groove 11 is provided with a clearance hole 112, which is used to avoid the camera of the mobile phone.
[0036] The roller assembly 20 can slide back and forth along the extension direction of the guide rail 12 and is detachably mounted on the guide rail 12. In this embodiment, the roller assembly 20 includes a bracket 21 and a roller body 22. The bracket 21 can slide back and forth along the extension direction of the guide rail 12 and is detachably mounted on the guide rail 12. The roller body 22 is mounted on the bracket 21 and moves with the back and forth sliding of the bracket 21. The bracket 21 is provided with a guide groove 211. When the bracket 21 slides on the guide rail 12, the guide rail 12 enters the guide groove 211. In addition, the bracket 21 is provided with a hinge portion 212, which is detachable. The shaft 13 is hinged to the ground. Specifically, the hinge 212 has a hinge groove 213 on its periphery, and the hinge groove 213 is hinged to the shaft 13 in a detachable manner. The bracket 21 is provided with a first limiting part 214, and the aforementioned guide rail 12 extends outward with a second limiting part 121. Both the front and rear ends of the second limiting part 121 are provided with notches 122 that are adapted to the first limiting part 214. The roller body 21 is located above the receiving part 14. When not rolling, the roller body 21 does not contact the mobile phone and the screen protector, ensuring that the screen protector can be properly applied to the mobile phone screen when applying the screen protector.
[0037] The working principle, usage method, or working process of this embodiment are described in detail below:
[0038] First, with the roller assembly 20 and the screen protector body 10 in an open state, the phone is placed into the receiving slot 11, and the protruding rib 111 abuts against and limits the peripheral side of the phone. The phone's camera is located in the clearance hole 112. Next, the roller assembly 20 is closed, and the first limiting part 214 passes through the notch 122 at the front end of the second limiting part 121, so that the roller assembly 20 and the screen protector body 10 are in a closed state. The release film on the surface of the screen protector is peeled off, and the screen protector is initially attached to the phone screen, so that the screen protector and the release film are stretched apart. An angle is formed, and then the hinge 212 is disengaged from the shaft 13. The roller assembly 20 is pulled backward so that the roller body 22 rolls the screen protector and the screen. The release paper passes through the slot. After the roller assembly slides into place, the screen protector application is completed. Finally, the roller assembly 20 is rotated counterclockwise around the hinge. The first limiting part 214 passes through the notch 122 at the rear end of the second limiting part 121. At this time, the roller body 22 does not contact the screen protector and the screen. Then the roller assembly is slid forward to reset.
[0039] The key design feature of this utility model is:
[0040] By detachably mounting the roller assembly on the guide rail, and allowing the roller assembly to slide back and forth along the extension direction of the guide rail, the phone screen and the screen protector can be perfectly adhered after the roller assembly rolls once along the extension direction of the guide rail. At this point, the roller assembly can be detached from the guide rail and reinstalled without sliding in the opposite direction, thus avoiding secondary rolling of the screen protector and preventing backward force from being applied, effectively preventing wrinkles after the screen protector is applied.
[0041] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
