Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, and in particular discloses a simple half-frame film applicator. Background Technology

[0002] Screen protector application tools fix the phone in place and create a template frame by replicating the phone's screen outline. Users simply place the phone and screen protector into this frame to solve the positioning problem and prevent the screen protector from being applied crookedly. However, existing screen protector application tools have some drawbacks. For example, existing applicators often achieve positioning by covering the entire edge of the device. These applicators need to precisely match the positions of buttons, lenses, charging ports, and other openings for different device models, resulting in high mold costs and poor compatibility. They are difficult to adapt to the diverse device models on the market, often making them disposable. Other simple positioning tools fix the device using only a single limiting structure, lacking a guiding and positioning design for the screen protector. During application, the screen protector is prone to vertical displacement, requiring repeated adjustments and reducing ease of use. Furthermore, most existing tools do not consider the ease of peeling off the release liner. During application, the screen protector must be positioned first and then manually removed. Removing the release liner can easily cause the aligned screen protector to shift, further reducing the success rate. These problems make it difficult for ordinary users to quickly achieve high-quality screen protector application, while professional screen protector services increase users' time and financial costs. Therefore, there is an urgent need for a screen protector application tool that is simple in structure, accurate in positioning, easy to operate, and highly compatible. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a simple half-frame film applicator.

[0004] To achieve the above objectives, this utility model provides a simple half-frame film applicator, comprising a positioning frame. The positioning frame has a first limiting part, two second limiting parts, a positioning lip, a wing plate, and a groove. The two second limiting parts are respectively bent and extended from both ends of the first limiting part, and the first limiting part and the two second limiting parts together form a U-shaped limiting groove with an opening. The positioning lip protrudes from the positioning frame and enters the positioning frame, extending along the length direction of the positioning frame and forming a guide groove. The guide groove is located above the limiting groove and is connected to the limiting groove. The positioning slots are connected; the wing plate protrudes from the positioning frame into the positioning frame, the positioning lip is located between the limiting part and the wing plate, and the wing plate covers the guide slot; the pull groove is located at the first limiting part and passes through the first limiting part and is connected to the limiting slot; the external smart terminal enters the limiting slot through the opening, the two second limiting parts are respectively clamped on both sides of the external smart terminal, the positioning lip abuts against the edge of the screen of the external smart terminal, the external protective film is installed between the wing plate and the screen of the smart terminal along the guide groove, and the release film of the external protective film passes through the pull groove.

[0005] Furthermore, the positioning lip is an integral U-shaped structure. The part of the positioning lip near the first limiting part is recessed along the width direction of the positioning lip to form a groove. The groove is connected to the pull groove, and the pull strip of the outer protective film passes through the groove.

[0006] Furthermore, the wing plate extends along the length of the positioning frame and surrounds it to form a U-shaped structure.

[0007] Furthermore, the wing plate is provided with an elastic auxiliary member near the first limiting part. When the external protective film is in the guide groove, the elastic auxiliary member is sandwiched between the wing plate and the external protective film. The elastic auxiliary member is used to abut against the functional membrane of the external protective film so that it contacts the screen of the external smart terminal to facilitate rapid exhaust.

[0008] Furthermore, the positioning frame is provided with a positioning protrusion, which protrudes from the first limiting part toward the limiting groove. When the external smart terminal is installed in the limiting groove, the positioning protrusion enters the charging port of the external smart terminal. The positioning protrusion is used to help fix the external smart terminal and prevent the external smart terminal from being installed upside down.

[0009] Furthermore, the positioning frame has a buckle or a fastener, or both.

[0010] Furthermore, there are two buckles, each protruding from one side of the two second limiting portions away from the positioning lip; when the external smart terminal is located in the limiting groove, the buckles and the positioning lip abut against the two sides of the external smart terminal that are far from each other; the buckles are point protrusions or strip protrusions.

[0011] Furthermore, there are two fixing members, which are located on the side of the two second limiting parts facing the limiting groove, and the external smart terminal is fixed in the limiting groove via the two fixing members; the fixing members are elastic or adhesive.

[0012] Furthermore, the positioning frame has multiple protruding parts, which are respectively located on one side of the two second limiting parts facing the limiting groove. When the external smart terminal is located in the limiting groove, the multiple protruding parts abut against both sides of the external smart terminal, so that a gap is formed between the second limiting part and the external smart terminal to accommodate the side wall button of the external smart terminal.

[0013] Furthermore, when the external smart terminal is placed in the limiting groove, the external smart terminal covers the groove, making the passage width of the groove less than the thickness of the functional film of the external protective film and greater than the thickness of the release film of the external protective film.

[0014] The beneficial effects of this utility model are:

[0015] (1) Triple positioning protection: The first limiting part and the two second limiting parts form a rigid frame, which tightly locks the mobile phone and prevents the mobile phone from shifting. Then, the positioning protrusions, buckles, and fasteners prevent the vertical displacement of the mobile phone. Finally, the three positioning protrusions achieve precise tracing of the mobile phone screen, ensuring that the protective film and the mobile phone screen are precisely aligned.

[0016] (2) Simple operation: The mobile phone slides into the positioning frame from the limiting groove, and the protective film slides into the positioning frame from the guide groove to achieve precise alignment between the mobile phone and the protective film. The release film can be directly removed through the pull groove at the bottom of the positioning frame without repeated adjustments.

[0017] (3) Strong compatibility: The positioning frame is a half-frame design, avoiding complex components such as mobile phone buttons and mobile phone lenses, making mold opening simple. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Example 1:

[0028] Please see Figures 1 to 2 As shown, this utility model discloses a simple half-frame film applicator, comprising a positioning frame 1. The positioning frame 1 has a first limiting part 11, two second limiting parts 12, a positioning lip 13, a wing plate 131, and a groove 17. The two second limiting parts 12 are respectively bent and extended from both ends of the first limiting part 11, and the first limiting part 11 and the two second limiting parts 12 enclose a U-shaped limiting groove with an opening. The positioning lip 13 protrudes from the positioning frame 1 and enters the positioning frame 1. The positioning lip 13 extends along the length direction of the positioning frame 1 and surrounds a guide groove, which is located above the limiting groove and communicates with it. Plate 131 protrudes into the positioning frame 1 from the positioning frame 1. Positioning lip 13 is located between the limiting part and the wing plate 131, and the wing plate 131 covers the guide groove. Pull groove 17 is located in the first limiting part 11 and passes through the first limiting part 11 and communicates with the limiting groove. External smart terminal 2 enters the limiting groove through the opening. Two second limiting parts 12 are respectively clamped on both sides of external smart terminal 2. Positioning lip 13 abuts against the edge of the screen of external smart terminal 2. External protective film 3 is inserted into the space between wing plate 131 and screen of smart terminal 2 along the guide groove. Release film 31 of external protective film 3 passes through pull groove 17.

[0029] In actual use, the positioning frame 1 is U-shaped. The connection between the first limiting part 11 and the two second limiting parts 12 is an arc or right angle that fits the outer contour of the external smart terminal 2. In this embodiment, it is an arc. The end of the positioning frame 1 has a wing plate 131, and the positioning lip 13 is located on the side of the wing plate 131 facing the limiting groove. When the external smart terminal 2 is located in the limiting groove, the three limiting parts abut against the side of the external smart terminal 2, and the positioning lip 13 abuts against one side of the screen of the external smart terminal 2. The positioning lip 13 only covers the edge of the screen of the external smart terminal 2, fixing the external smart terminal 2 while also achieving precise outlining of the screen of the external smart terminal 2. At this time, the wing plate 131 is located above the screen of the external smart terminal 2, and there is a gap between it and the screen of the external smart terminal 2. This gap is connected to the guide groove, and the external protective film 3 enters the gap between the wing plate 131 and the screen of the external smart terminal 2 through the guide groove. At this time, the release film 31 of the protective film 3 passes through the groove 17. When the functional film 33 of the protective film 3 separates from the release film 31, the wing plate 131 can prevent the functional film 33 from lifting up and causing the film to shift position.

[0030] Specifically, the positioning lip 13 is an integral U-shaped structure. The part of the positioning lip 13 near the first limiting part 11 is recessed along the width direction of the positioning lip 13 to form a groove. The groove is connected to the pull groove 17, and the pull strip 32 of the outer protective film 3 passes through the groove.

[0031] In actual use, the positioning lip 13 has the same width at the second limiting part 12 and at the first limiting part 11 near the second limiting part 12. The positioning lip 13 at the first limiting part 11 near the pull bar 32 is recessed along the width direction of the positioning lip 13 to form a groove, and the pull bar 32 passes through the groove to facilitate maintaining a balanced force when the release film 31 separates.

[0032] Specifically, the wing plate 131 extends along the length of the positioning frame 1 and forms a U-shaped structure.

[0033] In actual use, the wing plates 131 of the two second limiting parts 12 are also provided with arc-shaped plates, and the wing plate 131 of the first limiting part 11 is also provided with an elongated plate. The arc-shaped plate design allows users to install the external protective film 3 into the guide groove at a larger angle, optimizing the user experience. The wing plates 131 of the two second limiting parts 12 are arranged opposite to each other, and the external protective film 3 enters the guide groove from above the two oppositely arranged wing plates 131. The wing plates 131 are used to confine the external protective film 3 in the guide groove. The end of the wing plate 131 of the second limiting part 12 that first contacts the external protective film 3 is chamfered to avoid scratching the protective film. In this embodiment, the wing plate 131 can also be used to distinguish the front and back of the positioning frame 1, that is, the side of the wing plate 131 facing upward is the front.

[0034] Specifically, the wing plate 131 is provided with an elastic auxiliary member 132 near the first limiting part 11. When the external protective film 3 is located in the guide groove, the elastic auxiliary member 132 is sandwiched between the wing plate 131 and the external protective film 3. The elastic auxiliary member 132 is used to abut against the functional membrane 33 of the external protective film 3 so that it contacts the screen of the external smart terminal 2 to facilitate rapid exhaust.

[0035] In actual use, the wing plate 131 near the first limiting part 11 has an elastic auxiliary member 132. The elastic auxiliary member 132 can prevent the protective film from rubbing against the wing plate 131 on the first limiting part 11 and damaging the outer protective film 3 when the release film 31 of the outer protective film 3 is peeled off. On the other hand, when the release film 31 is peeled off, the outer protective film 3 squeezes the elastic auxiliary member 132, causing the elastic auxiliary member 132 to deform. After the release film 31 is peeled off, the functional film 33 does not immediately adhere to the screen of the outer smart terminal 2, and there is still an air gap. At this time, wait for the elastic force generated by the elastic auxiliary member 132 to recover its deformation or gently press the elastic force generated by the elastic auxiliary member 132 to make the functional film 33 adhere to the screen of the outer smart terminal 2 and quickly expel air. In addition, the wing plate 131 on the first limiting part 11 is provided with a groove for fitting the elastic auxiliary member 132.

[0036] Specifically, the positioning frame 1 is provided with a positioning protrusion 14, which protrudes from the first limiting part 11 toward the limiting groove. When the external smart terminal 2 is installed in the limiting groove, the positioning protrusion 14 enters the charging port of the external smart terminal 2. The positioning protrusion 14 is used to help fix the external smart terminal 2 and prevent the external smart terminal 2 from being installed upside down.

[0037] In actual use, the positioning protrusion 14 extends into the charging port of the external smart terminal 2, but does not contact the metal spring in the charging port. The positioning protrusion 14 can also serve as an indicator block to show whether the external smart terminal 2 and the positioning frame 1 are correctly installed. When the external smart terminal 2 is installed backwards or not in place, the positioning protrusion 14 cannot be inserted into the charging port.

[0038] Specifically, the positioning frame 1 is provided with two buckles 15, which are protruding from the side of the two second limiting parts 12 away from the positioning lip 13 respectively; when the external smart terminal 2 is located in the limiting groove, the buckles 15 and the positioning lip 13 respectively abut against the two sides of the external smart terminal 2 that are far from each other; the buckles 15 are point protrusions or strip protrusions.

[0039] In this embodiment, the buckle 15 is a dot-shaped protrusion. The two dot-shaped buckles 15 are located at the ends of the second limiting part 12. When the external smart terminal 2 is located in the limiting groove, the buckle 15 cooperates with the positioning lip 13 and abuts against the lower and upper surfaces of the external smart terminal 2 respectively, fixing the external smart terminal 2 in the limiting groove.

[0040] Specifically, the positioning frame 1 has multiple protruding parts 18, which are located on the side of the two second limiting parts 12 facing the limiting groove. When the external smart terminal 2 is located in the limiting groove, the multiple protruding parts 18 abut against the two sides of the external smart terminal 2, so that a gap is formed between the second limiting part 12 and the external smart terminal 2 to accommodate the side wall button of the external smart terminal 2.

[0041] In actual use, the first limiting part 11 and the two second limiting parts 12 are each provided with two protruding parts 18 on the side facing the limiting groove. When the external smart terminal 2 is installed into the limiting groove, the first limiting part 11 and the second limiting part 12 abut against the external smart terminal 2 through the protruding parts 18. This design optimizes the user experience without affecting the clamping force of the positioning frame 1 on the external smart terminal 2, and avoids excessive friction between the two second limiting parts 12 and the external smart terminal 2 when the external smart terminal 2 slides into the limiting groove, which would affect the user experience. In addition, the multiple protruding parts 18 abut against the side of the external smart terminal 2, so that a gap is formed between the second limiting part 12 and the external smart terminal 2 to accommodate the side wall button of the external smart terminal 2.

[0042] Specifically, when the external smart terminal 2 is placed in the limiting groove, the external smart terminal 2 covers the pull groove 17, so that the passage width of the pull groove 17 is less than the thickness of the functional film 33 of the external protective film 3 and greater than the thickness of the release film 31 of the external protective film 3.

[0043] In actual use, when the external smart terminal 2 is placed in the limiting groove, it will cover part of the pull groove 17. At this time, the actual width of the pull groove 17 that can pass through is less than the thickness of the functional film 33 of the external protective film 3, but greater than the thickness of the release film 31 of the external protective film 3. This design can prevent the functional film 33 from sliding out of the pull groove 17 when the release film 31 is pulled out through the pull groove 17.

[0044] Example 2:

[0045] Please see Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the buckle 15 in this embodiment is a strip-shaped protrusion. The two strip-shaped protrusions of the buckle 15 extend along the length direction of the corresponding second limiting part 12. When the external smart terminal 2 is located in the limiting groove, the buckle 15 cooperates with the positioning lip 13 and abuts against the lower surface and upper surface of the external smart terminal 2 respectively, fixing the external smart terminal 2 in the limiting groove.

[0046] The rest of this embodiment is the same as that of Embodiment 1. Features not explained in this embodiment are explained using the methods of Embodiment 1, and will not be repeated here.

[0047] Example 3:

[0048] Please see Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, two fasteners 16 are used instead of two clips 15 to fix the external smart terminal 2. The fasteners 16 in this embodiment are elastic members, and the two second limiting parts 12 fix the external mobile phone in the positioning frame 1 through the interference force generated by the two elastic members. The elastic members in this embodiment have a spring structure.

[0049] The rest of this embodiment is the same as that of Embodiment 1. Features not explained in this embodiment are explained using the methods of Embodiment 1, and will not be repeated here.

[0050] Example 4:

[0051] Please see Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, two fasteners 16 are used instead of two clips 15 to fix the external smart terminal 2. The fasteners 16 in this embodiment are adhesive components, and the two second limiting parts 12 are fixed to the external mobile phone in the positioning frame 1 by the adhesive force generated by the two adhesive components. The adhesive component in this embodiment is a residue-free adhesive.

[0052] The rest of this embodiment is the same as that of Embodiment 1. Features not explained in this embodiment are explained using the methods of Embodiment 1, and will not be repeated here.
