Description

Watch screen protector Technical Field

[0001] This utility model relates to the field of screen protector technology, and in particular to a screen protector for watches. Background Technology

[0002] With the improvement of living standards and the advancement of smart technology, smartwatches have gradually become integrated into people's daily lives. Since smartwatches are relatively expensive, users usually apply screen protectors, such as tempered glass screen protectors, to prevent scratches and damage. When applying screen protectors, users typically use a screen protector application device. Traditional devices have an adhesive backing that holds the screen protector in place before aligning it with the smartwatch. However, with traditional devices, the UV liquid adhesive can overflow, causing the screen protector to shift and resulting in misalignment. Furthermore, removing the screen protector from the backing is a cumbersome process. Summary of the Invention

[0003] The present invention provides a watch screen protector applicator to solve the technical problem that the protective film is prone to shifting when the screen protector is fixed, resulting in inaccurate alignment during application.

[0004] This utility model discloses a watch screen protector applicator, comprising:

[0005] The film application frame has a film application cavity with openings at both ends. One end of the film application cavity is the film application window, and the other end of the film application cavity is the watch placement window.

[0006] The adhesive-absorbing layer is a circumferentially connected and closed annular structure. The adhesive-absorbing layer has an inner ring facing the center of the film-applying cavity and an outer ring facing away from the center of the film-applying cavity. The entire inner ring of the adhesive-absorbing layer protrudes from the inner sidewall of the film-applying cavity. The adhesive-absorbing layer is located between the film-applying window and the watch placement window.

[0007] In one embodiment, the inner wall of the film-applying cavity is provided with an annular groove, and the outer ring of the adhesive-absorbing layer facing away from the film-applying cavity is embedded in the annular groove.

[0008] In one embodiment, the film-applying frame includes a first positioning frame and a second positioning frame, which are detachably fastened together along the depth direction of the film-applying cavity and enclose the film-applying cavity and the annular clamping groove.

[0009] In one embodiment, the watch screen protector includes a plurality of connecting posts spaced apart circumferentially along the screen protector cavity, each connecting post passing through the adhesive layer along the depth direction of the screen protector cavity and then fixedly connected to the screen protector frame.

[0010] In one embodiment, the adhesive layer is bonded to the first positioning frame and the second positioning frame on opposite sides along the depth direction of the film-applying cavity.

[0011] In one embodiment, a first annular protrusion extends from the outer side of the first positioning frame toward the second positioning frame along the depth direction of the film-applying cavity, and the first annular protrusion is connected to the edge of the second positioning frame to form the annular clamping groove; and / or, a second annular protrusion extends from the outer side of the second positioning frame toward the first positioning frame along the depth direction of the film-applying cavity, and the second annular protrusion is connected to the edge of the first positioning frame to form the annular clamping groove.

[0012] In one embodiment, the adhesive layer protrudes from the inner sidewall of the second positioning frame, and the inner side of the second positioning frame is provided with a first arc surface extending along the depth direction of the film-applying cavity. The first arc surface fits the side peripheral wall of the watch head. In the direction from the watch placement window toward the film-applying window, the radial dimension of the first arc surface corresponding to the film-applying cavity gradually decreases, and the radial dimension of the first arc surface gradually decreases until its end with the smallest radial dimension connects to the annular clamping groove.

[0013] In one embodiment, the inner ring portion of the adhesive-absorbing layer protruding from the inner wall of the film-applying cavity is provided with a second arc surface, which is on the extension path of the first arc surface. The first arc surface and the second arc surface together fit the curved portion of the watch's side wall.

[0014] In one embodiment, the inner sidewall of the first positioning frame protrudes beyond the inner sidewall of the second positioning frame, and the inner ring portion of the adhesive-absorbing layer protruding from the inner sidewall of the film-applying cavity is located between the inner sidewall of the first positioning frame and the inner sidewall of the second positioning frame.

[0015] In one embodiment, the adhesive layer is bonded to the inner wall of the film-applying cavity along the circumference of the film-applying cavity.

[0016] In one embodiment, the absorbent layer is an absorbent sponge.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] This utility model provides a watch screen protector applicator. Because an adhesive-absorbing layer is strategically placed within the applicator cavity to promptly absorb UV liquid adhesive overflowing from the edges of the watch screen during the applicator process, preventing it from curing, the adhesion of the protective film is greatly enhanced, thus improving the overall screen protector application effect. This is particularly suitable for curved watch screens. Furthermore, the watch screen protector applicator of this application has a simple structure and is easy to operate. Simply snap the watch head and the protective film together along the two ends of the applicator frame to apply the film, making it highly practical. Attached Figure Description

[0032] Referring to Figures 1-3, this application provides a watch screen protector 10, including a screen protector frame 100 and an adhesive absorption layer 200. The screen protector frame 100 is used to accommodate and fix the protective film 20 and the watch head 30. The adhesive absorption layer 200 has good liquid adsorption properties. During the screen protection process of the protective film 20 and the watch head 30, the adhesive absorption layer 200 is used to absorb the UV liquid adhesive that overflows between the two. Specifically, the screen protector frame 100 is provided with a screen protector cavity 110 with openings at both ends. One end of the screen protector cavity 110 is a screen protector window 111 for the protective film 20 to pass through and be fixed. The other end of the screen protector cavity 110 is a watch placement window 112 for the watch head 30 to pass through and be fixed, with the screen of the watch head 30 facing the protective film 20. The adhesive-absorbing layer 200 is a closed-loop structure with its ends connected circumferentially. The adhesive-absorbing layer 200 has an inner ring 210 facing the center of the film-applying cavity 110 and an outer ring 220 facing away from the center of the film-applying cavity 110. The inner ring 210 protrudes entirely from the inner wall of the film-applying cavity 110. The adhesive-absorbing layer 200 is located between the film-applying window 111 and the watch placement window 112. The inner wall of the inner ring 210 of the adhesive-absorbing layer 200 can adhere to the side wall of the watch head 30 to absorb excess UV liquid adhesive overflowing between the protective film 20 and the watch head 30, enhancing the adhesion between the protective film 20 and the screen of the watch head 30, improving the film-applying effect, and preventing excessive UV liquid adhesive from depositing and curing on the protective film 20 and the watch head 30, affecting the aesthetics and user experience. Optionally, the adhesive-absorbing layer 200 uses a porous medium material with strong liquid absorption capabilities, such as an absorbent sponge or porous soft silicone. Optionally, the protective film 20 can be a curved tempered glass film or a regular flat tempered glass film.

[0033] Preferably, referring to Figures 3 and 4, in one embodiment, the inner wall of the film-applying cavity 110 is provided with an annular groove 120, which communicates with the film-applying cavity 110. The outer ring 220 of the adhesive-absorbing layer 200 is embedded in the annular groove 120, thereby fixing the adhesive-absorbing layer 200 in the film-applying cavity 110. It should be noted that in other embodiments, the annular groove 120 is not required, and the adhesive-absorbing layer 200 can be directly bonded to the inner wall of the film-applying cavity 110 along the circumference. Alternatively, the adhesive-absorbing layer 200 can protrude from the inner wall of the film-applying cavity 110 to absorb UV liquid adhesive. Therefore, in this application, any structure that satisfies the condition that the inner ring 210 of the adhesive-absorbing layer 200 protrudes from the inner wall of the film-applying cavity 110 should be included.

[0034] Preferably, referring to Figures 5 and 6, in one embodiment, the film-applying frame 100 includes a first positioning frame 130 and a second positioning frame 140. The first positioning frame 130 and the second positioning frame 140 are detachably fastened together along the depth direction of the film-applying cavity 110 and enclose the aforementioned film-applying cavity 110 and an annular clamping groove 120. The detachable connection method is not limited to screw connection, snap-fit ​​connection, magnetic connection, adhesive, etc. It should be noted that in this application, the first positioning frame 130 and the second positioning frame 140 can also be integrally formed to form the annular clamping groove 120. Therefore, in this application, whether the first positioning frame 130 and the second positioning frame 140 are detachably fastened together is not limited.

[0035] Optionally, referring to Figures 3 and 5, in one embodiment, the watch screen protector 10 includes connecting posts 300 spaced apart circumferentially along the screen protector cavity 110. Each connecting post 300 sequentially passes through an adhesive absorption layer 200 along the depth direction of the screen protector cavity 110 and is fixedly connected to the screen protector frame 100 to further fix the adhesive absorption layer 200 within the annular groove 120 of the screen protector frame 100. Here, the connecting post 300 can sequentially pass through a first positioning frame 130, the outer ring 220 of the adhesive absorption layer 200, and a second positioning frame 140. The connecting post 300 is fixedly connected to one of the three, which not only further fixes the adhesive absorption layer 200 within the annular groove 120 of the screen protector frame 100, but also enables the first positioning frame 130 and the second positioning frame 140 to be detachably fastened together.

[0036] It should be noted that in other embodiments (not shown in the figures), the connecting post 300 may not be necessary. The adhesive-absorbing layer 200 can be bonded to the first positioning frame 130 and the second positioning frame 140 respectively on opposite sides along the depth direction of the film-applying cavity 110. That is, the adhesive-absorbing layer 200 is bonded to the inner wall of the annular clamping groove 120, thereby further fixing the adhesive-absorbing layer 200 within the annular clamping groove 120 of the film-applying frame 100. Therefore, in this application, the presence or absence of the connecting post 300 is not limited.

[0037] Optionally, in one embodiment, referring to FIG6, a first annular protrusion 131 extends from the outer side of the first positioning frame 130 along the depth direction of the film-applying cavity 110 toward the second positioning frame 140. The first annular protrusion 131 is connected to the edge of the second positioning frame 140 to form the aforementioned annular clamping groove 120. The connection structure here includes, but is not limited to, integral molding, snap-fit, hanging, etc. Similarly, in other embodiments, a second annular protrusion (not shown) extends from the outer side of the second positioning frame 140 along the depth direction of the film-applying cavity 110 toward the first positioning frame 130. The second annular protrusion is connected to the edge of the first positioning frame 130 to form the aforementioned annular clamping groove 120. The connection structure here includes, but is not limited to, integral molding, snap-fit, hanging, etc. In other embodiments, the first annular protrusion 131 and the second annular protrusion can also be provided simultaneously, and the two are connected along the depth direction of the film-applying cavity 110. The connection structure here includes, but is not limited to, integral molding, snap-fit, hanging, etc.

[0038] Preferably, referring to FIG6, in one embodiment, the adhesive-absorbing layer 200 protrudes from the inner sidewall of the second positioning frame 140. The inner side of the second positioning frame 140 is provided with a first arc surface 141 extending along the depth direction of the film-applying cavity 110. The first arc surface 141 fits against the side peripheral wall of the watch head 30. In the direction from the watch placement window 112 toward the film-applying window 111, the radial dimension of the first arc surface 141 gradually decreases corresponding to the film-applying cavity 110. The radial dimension of the first arc surface 141 gradually decreases until its end with the smallest radial dimension connects to the annular clamping groove 120, so that the first arc surface 141 fits tightly against the side peripheral wall of the watch head 30, improving the compact stability of the watch head 30 fixed in the film-applying cavity 110. It should be noted that the presence or absence of the first arc surface 141 is not limited if the compact stability of the watch head 30 is not considered. In other embodiments, the opening on one side of the watch placement window 112 can also be made of a deformable material to enhance the compact stability of the watch head 30.

[0039] Preferably, referring to FIG6, in one embodiment, the portion of the adhesive-absorbing layer 200 protruding from the inner wall of the inner ring 210 of the film-applying cavity 110 is provided with a second arc surface 211. The second arc surface 211 is on the extension path of the first arc surface 141 toward the film-applying window 111. The first arc surface 141 and the second arc surface 211 are together attached to the side peripheral wall of the watch head 30 to further improve the compact stability of the watch head 30 fixed in the film-applying cavity 110. Here, the first arc surface 141 and the second arc surface 211 can be arranged adjacently or spaced apart (as shown in FIG5). It should be noted that the presence or absence of the first arc surface 141 is not limited without considering the compact stability of the watch head 30. In other embodiments, the portion of the adhesive-absorbing layer 200 protruding from the inner ring 210 of the film-applying cavity 110 can also be made of a deformable material to enhance the compact stability of the watch head 30.

[0040] Preferably, referring to FIG6, in one embodiment, the inner sidewall of the first positioning frame 130 protrudes beyond the inner sidewall of the second positioning frame 140, and the inner ring 210 portion of the adhesive-absorbing layer 200 protruding beyond the inner sidewall of the film-applying cavity 110 is located between the inner sidewalls of the first positioning frame 130 and the second positioning frame 140, and the adhesive-absorbing layer 200 does not protrude beyond the inner sidewall of the first positioning frame 130. This design ensures a stable connection between the first positioning frame 130, the adhesive-absorbing layer 200, and the second positioning frame 140, thereby enhancing the overall structural compactness of the watch film applicator 10. It should be noted that, without considering the structural compactness of the watch film applicator 10, whether the inner ring 210 of the adhesive-absorbing layer 200 protrudes beyond the inner sidewall of the first positioning frame 130 or the inner sidewall of the second positioning frame 140 is not limited, as long as the inner ring 210 of the adhesive-absorbing layer 200 protrudes from the inner sidewall of the film-applying cavity 110.

[0041] The watch screen protector 10 provided in this application features an adhesive-absorbing layer 200 within the application cavity 110. This layer absorbs excess UV liquid adhesive that overflows from the screen edge of the watch face 30 during the application process, preventing it from curing. This significantly enhances the adhesion of the protective film 20, thereby improving the screen protection effect, especially suitable for curved watch screens. Furthermore, the watch screen protector 10 has a simple structure and is easy to operate. Application is achieved simply by snapping the watch face 30 and the protective film 20 together along the two ends of the application frame 100, making it highly practical.

[0042] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
