Technical Field
[0001] This utility model relates to the field of film applicators, and specifically to a film applicator. Background Technology
[0002] In today's digital age, various electronic devices such as smartphones, tablets, and computers have become indispensable tools in people's daily lives and work. As the core interface for information interaction, the screen of these electronic devices directly affects the user experience. To protect electronic device screens from scratches, wear, fingerprints, and accidental impacts, while maintaining the original clarity and aesthetics, screen protectors have become a common choice for users. Soft screen protectors, as a common screen protection material, are widely used in the field of electronic device screen protection due to their good flexibility, light transmittance, and certain cushioning properties. Therefore, screen protector application tools are often used to apply soft screen protectors.
[0003] Currently, there are many types of screen protector applicators on the market. These applicators typically consist of a positioning frame, an adsorption device, and auxiliary application components. In use, the user first places the electronic device within the positioning frame, aligning the screen with the frame's positioning structure. Then, the screen protector is placed on the adsorption device, where it is adhered to the frame. Next, the user uses the auxiliary application components to slowly and evenly push the screen protector towards the screen, starting from one end, until the screen protector completely covers the screen, completing the application process.
[0004] However, existing screen protector applicators still have some significant drawbacks in practical use. They are generally designed to fit specific phone models, ensuring accuracy but severely limiting versatility. As phone models are constantly updated, users need to purchase applicators compatible with newer models, increasing costs and wasting resources. Furthermore, maintaining a stock of applicators for multiple models increases management complexity and costs for repair shops and retailers. Therefore, developing a more versatile applicator that can adapt to various phone models is a pressing issue for the industry. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned defects and provide a film applicator to solve the technical problem that the existing film applicators in the background art have poor versatility, resulting in poor application effect during use, affecting actual use cost and wasting resources.
[0006] The objective of this utility model is achieved through the following means:
[0007] A film applicator includes a base and a sliding frame disposed on the base. The sliding frame is connected to the base via a sliding part and can reciprocate along the base. The base has a concave receiving groove, with four corners of the receiving groove having locking positions. The receiving groove also has limiting protrusions opposite to the locking positions. Adjusting blocks are detachably installed in the locking positions. The inner side of the adjusting blocks forms a locking part for holding the product, and the adjusting blocks are symmetrically distributed from left to right. The sliding frame is slidably connected to the base. A film pushing component is bonded to the sliding frame via a connecting groove. One end of the film pushing component extends toward the receiving groove and forms an inclined pressing part. One end of the base has an outwardly extending hanging ear. The hanging ear has a positioning groove and a hanging hole communicating with the positioning groove. A positioning frame is disposed at the end of the base near the hanging ear, and one end of the positioning frame extends obliquely toward the top of the base.
[0008] Furthermore, as described above, the base has outwardly protruding guide edges on both sides. A limiting part is provided at the end of the guide edge near the hanging ear. The sliding frame can slide through the sliding part along the end of the guide edge away from the limiting part and can reciprocate along the guide edge.
[0009] By setting outwardly protruding guide edges on both sides of the base and adding a limiting part at one end near the hanging lug, the sliding trajectory of the sliding frame can be precisely guided and the end can be limited. This allows the sliding frame to slide stably back and forth along a fixed path, avoiding deviation or derailment during operation. At the same time, the limiting part can prevent the sliding frame from sliding excessively and causing the structure to fall off.
[0010] This structure improves the standardization and reliability of screen protector operation through physical constraints, making it particularly suitable for screen protector application on mobile phones of different sizes. It ensures that the screen protector is always precisely aligned during the application process, effectively solving the problem of poor adaptability caused by the loose structure of traditional screen protectors.
[0011] Furthermore, as described above, the sliding part is composed of a sliding groove and a retaining protrusion. The retaining protrusion is formed on the inner side of the sliding frame, and the sliding groove is formed between the sliding frame and the retaining protrusion through the positioning part, so that the sliding frame can reciprocate along the guide edge through the sliding groove.
[0012] The sliding part, composed of a sliding groove and a retaining protrusion, forms a stable sliding connection structure through the interlocking of the retaining protrusion on the inner side of the sliding frame and the guide edge.
[0013] Furthermore, as described above, the base is provided with a clearance opening that communicates with the receiving groove, and the receiving groove is provided with a plurality of positioning protrusions that are symmetrically distributed from left to right.
[0014] A modular adaptable structure is formed by setting clearance openings and symmetrically distributed positioning protrusions in the bottom tray receiving groove. The clearance openings are compatible with protruding parts on the back of different mobile phone models, such as cameras, avoiding interference during screen protector application. The positioning protrusions provide support and positioning for the mobile phone body through multi-point contact, thus creating a gap between them and the bottom wall of the receiving groove.
[0015] Furthermore, as described above, the adjusting block is inserted into the slot, and one end of the adjusting block makes contact with the limiting protrusion. The adjusting block is arranged in an "L" shape.
[0016] Featuring an "L"-shaped detachable adjustable clip, this screen protector allows for quick installation and removal through the interaction of the clip and limiting protrusions. The inner side of the clip forms a holding section that engages and holds the four corners of the phone, while the symmetrical left-right distribution ensures compatibility with different phone widths. When changing to a different phone size, only the corresponding adjustable clip needs to be replaced, avoiding the cost of replacing the entire screen protector applicator. This modular design allows a single screen protector applicator to cover multiple phone models, significantly reducing user costs and inventory management pressure.
[0017] Furthermore, as described above, the adjustment block is made of foam or EVA cotton.
[0018] Foam or EVA cotton is selected as the material for the adjustment clips. Utilizing their flexibility and compressibility, the clips can adapt to varying curvatures of different phone edges. The soft material provides cushioning during film application, preventing scratches from the hard clips on the phone frame, while deformation compensation ensures a tighter fit.
[0019] It is especially suitable for curved screen phones or models with irregular edges. While ensuring the reliability of the fixed position, it improves the compatibility of the device with a variety of models and solves the problem of poor compatibility of traditional hard cards.
[0020] Furthermore, as described above, the base has an clearance groove, and the positioning frame has a protruding positioning block.
[0021] By setting a clearance groove in the bottom support and adding a raised positioning block to the positioning frame, the raised positioning block is used to hold the soft film, thereby enhancing the positioning effect of the soft film and the stability during bonding.
[0022] The beneficial effects of this utility model are as follows: By setting slots at the four corners of the receiving groove and installing detachable adjustment blocks, users can replace the corresponding adjustment blocks according to different mobile phone models. This creates a holding space between the adjustment blocks for matching product models and sizes. Compared with the limitation of existing screen protector applicators that only support a single model, this significantly improves the universality and applicability of the screen protector applicator. It avoids the problem of screen protector applicators being idle or requiring repeated purchases due to mobile phone model updates. Users only need to replace the corresponding adjustment blocks, thereby reducing user costs and minimizing resource waste. The reciprocating sliding characteristics of the sliding frame combined with the inclined pressing part of the film pusher improves the adhesion effect of the screen protector. Furthermore, the hook part allows for gripping during screen protector application, improving stability and enhancing ease of operation and user experience. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0035] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.
[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0037] In this embodiment, refer to Figures 1-6 The specific implementation of the film applicator includes a base 100 and a sliding frame 200 disposed on the base 100. The sliding frame 200 is connected to the base 100 via a sliding part and can reciprocate along the base 100. The base 100 is provided with a concave receiving groove 101. Each of the four corners of the receiving groove 101 is provided with a locking position 102, and the receiving groove 101 is provided with a limiting protrusion 103 opposite to the locking position 102. An adjusting locking block 300 is detachably installed in the locking position 102. The inner side of the adjusting locking block 300 forms a locking part 301 for holding the product, and the adjusting locking block 300 is oriented left and right. The sliding frame 200 and the base 100 are symmetrically distributed and slidably connected. A film pusher 400 is bonded to the sliding frame 200 through a connecting groove 201. One end of the film pusher 400 extends into the receiving groove 101 and forms an inclined pressing part. One end of the base 100 forms an outwardly extending hanging ear 104. A positioning groove 105 is provided on the hanging ear 104, and a hanging hole 106 communicating with the positioning groove 105 is provided on the hanging ear 104. A positioning frame 107 is provided at one end of the base 100 near the hanging ear 104. One end of the positioning frame 107 extends inclinedly towards the top of the base 100.
[0038] In this embodiment, the adjusting block 300, the sliding frame 200, and the film-pushing component 400 are all detachably connected, allowing users to replace individual components based on wear or functional requirements without having to scrap the entire device. For example, when the film-pushing component wears out due to long-term use, only the adhesive film-pushing component 400 needs to be replaced, extending the service life of the applicator and reducing maintenance costs.
[0039] The base 100 has outwardly protruding guide baffles 108 on both sides. A limiting part 109 is provided at one end of the guide baffle 108 near the ear part 104. The sliding frame 200 can slide through the sliding part along the end of the guide baffle 108 away from the limiting part 109 and can slide back and forth along the guide baffle 108.
[0040] By providing outwardly protruding guide flanges 108 on both sides of the base 100 and adding a limiting part 109 at one end near the lug 104, the sliding trajectory of the sliding frame 200 can be precisely guided and its end limited. This allows the sliding frame 200 to slide stably back and forth along a fixed path, preventing deviation or derailment during operation. At the same time, the limiting part 109 can prevent the sliding frame 200 from sliding excessively and causing the structure to fall off.
[0041] This structure improves the standardization and reliability of screen protector operation through physical constraints, making it particularly suitable for screen protector application on mobile phones of different sizes. It ensures that the screen protector is always precisely aligned during the application process, effectively solving the problem of poor adaptability caused by the loose structure of traditional screen protectors.
[0042] In practice, the base 100 is made of plastic or metal.
[0043] The sliding part consists of a sliding groove 202 and a retaining protrusion 203. The retaining protrusion 203 is formed on the inner side of the sliding frame 200. The sliding groove 202 is formed between the sliding frame 200 and the retaining protrusion 203 through the positioning part, allowing the sliding frame 200 to reciprocate along the guide edge 108 via the sliding groove 202. The sliding part, composed of the sliding groove 202 and the retaining protrusion 203, forms a stable sliding connection structure through the interlocking cooperation between the retaining protrusion 203 and the guide edge 108 on the inner side of the sliding frame 200.
[0044] In the specific implementation process, the sliding component is made of plastic or metal. The sliding component is paired with the guide baffle 108 through the sliding groove 202. The guide baffle can prevent the sliding component from falling off.
[0045] The base 100 is provided with a clearance opening 110 that communicates with the receiving groove 101, and the receiving groove 101 is provided with a plurality of positioning protrusions 111 that are symmetrically distributed from left to right.
[0046] By providing a clearance opening 110 and symmetrically distributed positioning protrusions 111 in the receiving groove 101 of the base 100, a modular adaptation structure is formed. The clearance opening 110 is compatible with protruding components on the back of different mobile phone models, such as cameras, avoiding interference during screen protector application. The positioning protrusions 111 provide support and positioning for the mobile phone body through multi-point contact, thereby creating a gap between them and the bottom wall of the receiving groove 101.
[0047] The adjusting block 300 is inserted into the locking position 102, and one end of the adjusting block 300 is in contact with the limiting protrusion 103. The adjusting block 300 is arranged in an "L" shape.
[0048] The device employs an "L"-shaped detachable adjustable clip 300, which allows for quick installation and removal through the cooperation of the clip 102 and the limiting protrusion 103. The retaining portion 301 formed on the inner side of the clip can contact and retain the four corners of the phone, while the symmetrical distribution design ensures compatibility with different phone widths. When changing to a different phone size, only the corresponding adjustable clip 300 needs to be replaced to achieve adaptation, avoiding the cost waste of replacing the entire screen protector applicator. This modular design allows a single screen protector applicator to cover multiple phone models, significantly reducing user costs and inventory management pressure.
[0049] The adjustment clip 300 is made of foam or EVA foam. By selecting foam or EVA foam as the material for the adjustment clip 300, its flexibility and compressibility allow the retaining part 301 to adapt to different curvature changes of the phone's edges. The soft material forms a buffer during the film application process, preventing scratches to the phone's frame from the hard clips, and simultaneously achieving a tighter fit through deformation compensation.
[0050] It is especially suitable for curved screen phones or models with irregular edges. While ensuring the reliability of the fixed position, it improves the compatibility of the device with a variety of models and solves the problem of poor compatibility of traditional hard cards.
[0051] The base 100 has an clearance groove 112, and the positioning frame 107 has a raised positioning block. By providing the clearance groove 112 in the base 100 and adding the raised positioning block in the positioning frame 107, the raised positioning block is used to hold the soft film, thereby enhancing the positioning effect of the soft film and the stability during bonding.
[0052] The sliding frame 200 is connected to the base via a sliding part and can reciprocate along the base. The pusher 400, which is bonded inside, extends to the receiving groove and forms an inclined pressing part. This allows the pusher 400 to push the protective film onto the mobile phone screen smoothly along a stable trajectory during the application process, reducing the generation of air bubbles or misalignment during application and further improving the application efficiency.
[0053] The specific usage process in this embodiment is as follows:
[0054] Combination state: The screen protector in this embodiment is used for applying soft screen protectors to mobile phones, such as hydrogel films. The sliding bracket 200 is slid along the guide edge 108 to the limiting part 109 via the sliding groove 202. For example, the mobile phone used in this embodiment is a Huawei Mate70 Pro. Four corresponding adjustment blocks 300 are selected and installed on the four corner slots 102 in the receiving groove 101, so that the four adjustment blocks 300 form a space for holding the mobile phone. The mobile phone is installed in the receiving groove 101, and the holding part 301 of the adjustment block 300 contacts and holds the side of the mobile phone.
[0055] The soft film is held and positioned by the hanging structure and the ear positioning block on the positioning frame 107. The protective paper on the soft film is torn off, and the sliding frame 200 is pushed to move closer to the mobile phone, so that the sliding part presses the soft film through the film pressing part. The film application action is completed by sliding the sliding frame 200. The reciprocating sliding characteristics of the sliding frame 200 and the inclined film pressing part of the film pushing part 400 are combined to improve the film application effect. The ear 104 is provided so that the film can be held during the application, thereby improving the stability of the film application, improving the convenience of operation and user experience.
[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
