Description

Technical Field

[0001] The utility model relates to the field of mobile phone screen protectors, specifically a universal mobile phone screen protector applicator. Background Technology

[0002] A screen protector applicator is an auxiliary tool designed to solve the problems of air bubbles and misalignment that often occur when manually applying screen protectors. Its main body is a plastic or metal frame that secures the phone with clips and has built-in positioning slots to ensure precise alignment of the screen protector with the screen. Some high-end models come with accessories such as dust clips and scrapers, enabling a one-step process of "removing the screen protector, cleaning the dust, and applying the protector," thus lowering the barrier to entry.

[0003] Existing screen protector applicators are usually disposable, or even if they are not disposable, they can only be used for specific models, resulting in poor compatibility. Screen protectors that are compatible with multiple models have problems such as inaccurate clamping and complicated operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a universal screen protector applicator for mobile phones, which has the advantages of good compatibility, a fast and simple application process, precise application, and compatibility with multiple mobile phone models, effectively solving the problems existing in the prior art.

[0005] The objective of this utility model is achieved through the following technical solution: This universal screen protector applicator includes an applicator body, which comprises a housing and a clamping mechanism. The housing has a flat and easily identifiable placement area for the phone, allowing users to quickly understand how to use it. The clamping mechanism is located at the edge of the placement area and clamps the sidewall of the phone. The width of the clamping mechanism is adjustable to accommodate phones with different spacings and can clamp the phone from different directions, preventing displacement within the placement area. One applicator body is compatible with multiple brands and models of phones and can firmly clamp phones of different sizes. The clamping mechanism includes a clamping arm and a spring. The clamping arm, pulled by the spring, has a rebound force, ensuring a firm fit against the phone's sidewall when no external force is applied. The applicator body also includes a positioning element for holding the screen protector and suspending it directly above the phone screen, eliminating the need for users to calibrate the relative position of the screen protector and the phone, ensuring accurate and quick application of the screen protector to the phone screen.

[0006] In one embodiment, the clamping mechanism includes a horizontal clamping mechanism and a vertical clamping mechanism. Most existing mobile phones are rectangular, so clamping in both the horizontal and vertical directions is sufficient to fix the phone. Each horizontal and vertical clamping mechanism has at least one spring-loaded clamping arm. Pulling a movable clamping arm allows the phone to be inserted. The positioning element is located on the upper and lower edges of the box body and is composed of multiple pillars. By simply setting corresponding openings on both sides of the screen protector, different screen protectors can be positioned directly above the screen of the phone that matches the screen protector when placed on the screen protector body.

[0007] In one embodiment, the box body is provided with a placement slot for placing the clamping mechanism. There are two placement slots, namely placement slot one and placement slot two. The horizontal clamping mechanism is located in placement slot one, and the vertical clamping mechanism is located in placement slot two. The horizontal clamping mechanism and the vertical clamping mechanism are arranged alternately so that they can operate independently of each other during clamping operations, preventing interference between them and ensuring the clamping effect.

[0008] In one embodiment, the lateral clamping mechanism has two clamping arms that are pulled by a spring. The clamping arms are first clamping arms. The two first clamping arms are distributed in a mirror image in the placement groove, which can exert force evenly and clamp both sides of the mobile phone at the same time. The first clamping arms have an L-shaped arm protruding from the top surface of the box and a connecting arm hidden in the placement groove. The protruding part of the L-shaped arm is used to fit against the side wall of the mobile phone.

[0009] In one embodiment, a linkage synchronous gear is also provided between the two first clamping arms. The linkage synchronous gear is located in the middle of the placement groove and can only rotate. The connecting arm is provided with a toothed track that meshes with the linkage synchronous gear. Through the cooperation between the linkage synchronous gear and the toothed track, the expansion / closing degree of the two first clamping arms is always consistent and there is no deviation, ensuring that the mobile phone is located in the center of the placement area after it is clamped.

[0010] In one embodiment, a locking block is provided in the placement slot 1, and a locking post is provided on the connecting arm. The locking block, locking post, side wall of the connecting arm, and side wall of the placement slot 1 together form a cavity structure to clamp the spring 1 in the cavity, so that the spring 1 can only undergo linear contraction / expansion to prevent its deformation. A limiting member is also provided between the first clamping arm and the bottom surface of the placement slot 1 to restrict the movement of the first clamping arm, so that the first clamping arm can only move laterally.

[0011] In one embodiment, the limiting member has at least one limiting groove and one snap-in member. After the snap-in member is inserted into the limiting groove, the two first clamping arms can only move left and right in the horizontal direction, ensuring that the pressure generated during clamping is perpendicular to the side wall of the mobile phone, so that the mobile phone can be kept perpendicular to the top / bottom edge of the box. One of the limiting groove and the snap-in member is provided on the placement groove, and the other is correspondingly provided on the connecting arm.

[0012] In one embodiment, the upper and lower ends of the box have walls that protrude above the middle of the box, making the box U-shaped. The positioning element is set on the wall, and the wall limits the distance between the screen protector and the phone screen by its own height, so that the user can simply press the screen protector to adhere it to the screen after calibration. The longitudinal clamping mechanism has a clamping arm that is pulled by a spring, which is the second clamping arm. The upper wall forms a clamping arm that is not pulled by the spring. Together, they form the longitudinal clamping mechanism. That is, the second clamping arm generates a pushing force to push the top wall of the phone against the upper wall to complete the clamping. The wall has a pull strip opening for the screen protector to pass through. The pull strip opening has a foolproof effect to prevent the user from placing the screen protector in the wrong orientation, such as the screen protector camera opening facing the opposite direction to the phone camera.

[0013] In one embodiment, the box body is provided with a groove for restricting the second clamping arm, and the back of the second clamping arm is provided with a slider for inserting into the groove. The groove and the slider cooperate to allow the second clamping arm to move only longitudinally, precisely and horizontally pushing the mobile phone so that its top wall fits against the wall above. The back of the second clamping arm is provided with a clamping groove for placing a second spring, which provides power to the second clamping arm. The middle part of the box body is provided with a sliding groove for inserting the clamping groove, further limiting the sliding direction of the second clamping arm.

[0014] In one embodiment, a rod is provided in the clamping groove, and an insert is provided at the top of the rod. The clamping groove is provided with a groove for inserting the insert. The bottom of the sliding groove is provided with a rod opening to avoid the rod. The second spring is penetrated by the rod and clamped between the insert and the rod opening. The insert and the rod opening form a fit to restrict the direction of the rod's sliding. The rod can prevent the second spring from bending, and the insert also has the effect of converting the self-restoring force generated when the second spring is deformed into the clamping force of the second clamping arm.

[0015] In one embodiment, the box body is further provided with a locking component that can lock the sliding of the second clamping arm. The locking component is provided with a hook, and the top of the hook is provided with a spring three that provides a pushing force to keep the hook in the extended state. The middle part of the hook is rotatably mounted on a cylinder provided in the box body, so that the hook can retract. A button is provided on one side of the bottom of the hook, and the button is used to trigger the hook to retract. The side wall of the box body is provided with an opening for the button to pop out. The clamping groove is provided with a protrusion that cooperates with the hook. Through the cooperation of the two, the second clamping arm is locked.

[0016] Beneficial effects 1. In terms of performance: (1) It is simple to use and easy to get started; (2) Stable clamping and precise positioning; (3) The application process is simple and the application is precise; (4) One screen protector applicator is compatible with both flat and curved screen mobile phones on the market.

[0017] 2. In terms of structure: (1) The longitudinal clamping mechanism is controlled by the hook, which can keep the longitudinal clamping mechanism in an expanded state, making it convenient for the user to adjust the transverse clamping mechanism; (2) The transverse clamping mechanism is equipped with a linkage synchronous gear, which enables the two first clamping arms to perform expansion / contraction activities synchronously, ensuring the clamping effect; (3) A positioning component is provided, which consists of two rows of columns with different numbers of columns, so as to achieve accurate positioning and also have the effect of preventing mistakes.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0026] Please see Figure 1-16 This is a universal screen protector applicator for mobile phones, comprising an applicator body 1, a housing 2, and a clamping mechanism 3. The housing 2 has a placement area 4 for placing the mobile phone in its center. The clamping mechanism 3 is located at the edge of the placement area 4 and is used to clamp the side wall of the mobile phone. The width of the clamping mechanism 3 is adjustable to accommodate mobile phones of different sizes, and the clamping mechanism 3 can clamp the mobile phone from different directions, preventing it from shifting within the placement area 4. The clamping mechanism 3 has clamping arms and springs; the clamping arms are pulled by the springs, giving them a rebound force. The applicator body 1 also has a positioning element 6, which is used to place the screen protector and suspend it directly above the mobile phone screen. To use, first clean the phone screen, then pull open the clamping mechanism 3 and place the phone in the placement area 4. Pulling open the clamping mechanism 3 will compress the spring. After losing external force, the clamping arm will be subjected to the spring's rebound force, generating clamping force to accurately clamp the phone in the center of the placement area 4. After the clamping mechanism 3 completes its clamping work, the screen protector can be placed on the positioning piece 6. After the screen protector is fully inserted, it will be positioned directly above the phone screen. Peel off the film from the side of the screen protector that is in contact with the screen, and gently press the screen protector to adhere it to the phone screen. This will achieve a precise fit between the screen protector and the phone screen. The screen protector can be tempered glass, hydrogel, or a regular protective film.

[0027] Preferably, the clamping mechanism 3 is provided with a transverse clamping mechanism 7 and a longitudinal clamping mechanism 8, wherein the transverse clamping mechanism 7 and the longitudinal clamping mechanism 8 have at least one clamping arm that is pulled by a spring, and the positioning member 6 is provided on the upper and lower edges of the box body 2.

[0028] By adopting the above technical solutions, this application provides combinations of different clamping methods: When the clamping method is one clamping arm pulled by a spring and the other is a fixed clamping arm, that is, the horizontal mechanism 7 or the vertical clamping mechanism 8 is composed of a clamping arm fixed to one side of the placement area 4 and a pullable clamping arm. When clamping the side wall of the mobile phone, the movable clamping arm is pulled open, so that the clamping arm pulls the spring. Then the side wall of the mobile phone is attached to the fixed clamping arm. Then the pullable clamping arm is released. The pulled spring loses external force and automatically retracts, generating clamping force to clamp the mobile phone in the middle of the horizontal clamping mechanism 7 or the vertical clamping mechanism 8. When the clamping method consists of two spring-pulled clamping arms without a fixed clamping arm, i.e., the horizontal mechanism 7 or the vertical clamping mechanism 8 is composed of two pullable clamping arms, when clamping the side wall of the mobile phone, the movable clamping arm is pulled open, causing the clamping arm to pull the spring open, and then the side wall of the mobile phone is pressed against the fixed clamping arm. Then the pullable clamping arm is released, and the pulled spring loses external force and automatically retracts, generating clamping force to clamp the mobile phone between the two movable clamping arms. Since the forces are mutual, the thrust generated by the pulled spring when it self-recovers will act on the other clamping arm through the mobile phone. After the clamping arm is subjected to force, it will apply the thrust to the spring connected to it. Therefore, the clamping arm will also shift, so that the mobile phone is clamped exactly in the middle of the horizontal clamping mechanism 7 or the vertical clamping mechanism 8. Furthermore, this application also provides a scheme in which the horizontal clamping mechanism 7 consists of two spring-loaded clamping arms, and the vertical clamping mechanism 8 consists of one spring-loaded clamping arm and the other is a fixed clamping arm. In use, first pull open the movable clamping arm on the vertical clamping mechanism 8, then open the clamping arm on either side of the horizontal clamping mechanism 7, and place the mobile phone on the placement area 4.

[0029] Preferably, the box body 2 is provided with a placement slot for placing the clamping mechanism 3. There are two placement slots, namely placement slot one 9 and placement slot two 10. The transverse clamping mechanism 7 is located in placement slot one 9, and the longitudinal clamping mechanism 8 is located in placement slot two 10. The positioning member 6 is composed of multiple columns.

[0030] By adopting the above technical solution, during installation, the horizontal clamping mechanism 7 is installed in the placement slot 1 9, which is equipped with a cover for shielding. The vertical clamping mechanism 8 is installed in the placement slot 2 10, which is also equipped with a cover for shielding. The two sides of the screen protector have openings for inserting the positioning component 6. The positioning component 6 is composed of two rows of columns with different numbers of columns. The different number of columns can play a foolproof role. The screen protector manufacturer can calculate the coordinates of the four corners of the screen protector based on the coordinates of the columns to ensure that the screen protector floats exactly above the screen of the phone after being fitted with the positioning component 6.

[0031] Preferably, the transverse clamping mechanism 7 is provided with two clamping arms pulled by spring 5. The clamping arms are first clamping arms 11. The two first clamping arms 11 are mirror-distributed in the placement groove 9. The first clamping arms 11 are provided with an L-shaped arm 12 protruding from the top surface of the box body 2 and a connecting arm 13 hidden in the placement groove 9.

[0032] By adopting the above technical solution, the two first clamping arms 11 are mirror-distributed on the left and right sides of the placement area 4. The side protrusion of the L-shaped arm 12 is used to clamp the left and right side walls of the mobile phone, while the connecting arm 13 is connected to the spring 5. When the user pulls the L-shaped arm 12, the force will be transmitted to the spring 5 through the connecting arm 13. When the external force is lost, the self-resetting pull of the spring 5 will cause the first clamping arms 11 to reset together. The reset pull is also the clamping force for clamping the mobile phone.

[0033] Preferably, a linkage synchronous gear 14 is also provided between the two first clamping arms 11. The linkage synchronous gear 14 is located in the middle of the placement groove 9 and can only rotate. The connecting arm 13 is provided with a toothed path 15 that meshes with the linkage synchronous gear 14.

[0034] By adopting the above technical solution, when the user pulls open one of the first clamping arms 11 through the L-shaped arm 12, the toothed groove 15 on the connecting arm 13 will mesh with the linkage synchronous gear 14, causing the linkage synchronous gear 14 to rotate. At the same time, the linkage synchronous gear 14 will mesh with the toothed groove 15 on the other first clamping arm 11, causing the first clamping arm 11 to move in the opposite direction but with the same length as the first clamping arm 11 that was pulled open. When the user's finger leaves the pulled-open L-shaped arm 12, since the two first clamping arms 11 are pulled open to the same extent, the contraction force generated by the spring-5 is the same. Therefore, the clamping force generated by the two first clamping arms 11 is the same, and the mobile phone will be clamped in the middle of the horizontal clamping mechanism 7. Furthermore, due to the presence of the linkage synchronous gear 14, when the spring-5 contracts, the displacement of the two toothed grooves 15 will be transmitted to each other through the linkage synchronous gear 14. Even if the contraction forces generated by the two spring-5 are different, the two first clamping arms 11 can be forced to move in opposite directions but with the same distance through the meshing of the linkage synchronous gear 14 and the toothed groove 15.

[0035] Preferably, a locking block 16 is provided in the placement groove 9, and a locking post 17 is provided on the connecting arm 13. The locking block 16, the locking post 17, the side wall of the connecting arm 13 and the side wall of the placement groove 9 together form a cavity structure to clamp the spring 5 in the cavity. A limiting member is also provided between the first clamping arm 11 and the bottom surface of the placement groove 9 to restrict the movement of the first clamping arm 11.

[0036] By adopting the above technical solution, the spring-5 can only move in the cavity formed by the four components: the side wall of the locking block 16, the locking post 17, the side wall of the connecting arm 13, and the side wall of the placement groove 9. This prevents the spring-5 from bending, and the limiting component restricts the direction and distance of movement of the first clamping arm 11, further ensuring that the spring-5 can only be compressed or expanded linearly.

[0037] Preferably, the limiting member has at least one limiting groove 18 and one snap-in member 19. After the snap-in member 19 is placed in the limiting groove 18, the two first clamping arms 11 can only move left and right in the horizontal direction. One of the limiting groove 18 and the snap-in member 19 is provided on the placement groove 9 and the other is provided on the connecting arm 13.

[0038] By adopting the above technical solution, two limiting grooves 18 are provided, one located on the bottom surface of the connecting arm 13 and the other located on the placement groove 9. The limiting groove 18 located on the connecting arm 13 is long and rectangular, while the limiting groove 18 located on the placement groove 9 is capsule-shaped. Two locking members 19 are also provided. One is a cylinder protruding from the bottom surface of the connecting arm 13, which is used to be placed into the capsule-shaped limiting groove 18. The other locking member 19 is long and protruding from the top surface of the placement groove 9, which is used to be placed into the long and rectangular limiting groove 18. The two limiting grooves 18 and the two locking members 19 adopt opposite distribution methods, which effectively improves the limiting effect.

[0039] Preferably, the upper and lower ends of the box body 2 are provided with walls 20 that protrude above the middle of the box body 2, making the box body 2 U-shaped. The positioning member 6 is provided on the wall 20. The longitudinal clamping mechanism 8 is provided with a clamping arm that is pulled by a second spring 51. This clamping arm is the second clamping arm 21. The upper wall 20 forms a clamping arm that is not pulled by the second spring 51. The two together form the longitudinal clamping mechanism 8. The wall 20 is provided with a pull strip opening 22 for the mobile phone film pull strip to pass through.

[0040] By adopting the above technical solution, when using it, first open the horizontal clamping mechanism 7, then activate the vertical clamping mechanism 8. Simply pull the second clamping arm 21 downwards. After placing the phone in and releasing it, the spring 51 will no longer be under force and will tighten and reset, causing the second clamping arm 21 to generate clamping force and form a clamping groove with the upper wall 20, clamping the upper and lower walls of the phone. Then release the horizontal clamping mechanism 7 to complete the clamping of the phone. Place the phone screen protector on the positioning piece 6, and then pass the pull strip through the pull strip opening 22. At this time, the phone screen protector is exactly above the phone screen. Pull the pull strip to expose the side of the phone screen protector that is in contact with the phone screen, and then gently press the phone screen protector to make it adhere to the phone screen.

[0041] Preferably, the box body 2 is provided with a sliding groove 23 for limiting the second clamping arm 21, the back of the second clamping arm 21 is provided with a slider 24 for inserting into the sliding groove 23, the back of the second clamping arm 21 is provided with a clamping groove 25 for placing the second spring 51, and the middle part of the box body 2 is provided with a sliding groove 26 for inserting the clamping groove 25.

[0042] By adopting the above technical solution, when the second clamping arm 21 is pulled, the slider 24 is restricted by the slide groove 23 and can only slide in the slide groove 23, thereby restricting the sliding direction of the second clamping arm 21. At the same time, the spring 21 is compressed in the clamping groove 25, and the slide groove 26 also restricts the sliding direction of the clamping groove 25, further restricting the movement direction of the second clamping arm 21.

[0043] Preferably, the clamping groove 25 is provided with a rod 27, the top of the rod 27 is provided with an insert 28, the clamping groove 25 is provided with a groove 29 for inserting the insert 28, the bottom of the sliding groove 26 is provided with a rod opening 30 to avoid the rod 27, and the spring 51 is penetrated by the rod 27 and clamped between the insert 28 and the rod opening 30.

[0044] By adopting the above technical solution, during installation, the second clamping arm 21 is placed in the second placement groove 10, the slider 24 is placed in the sliding groove 23, and the clamping groove 25 is placed in the sliding groove 26. Then, the rod 27 is inserted from the upper end of the second spring 51, and the rod 27 and the insert 28 are installed in the clamping groove 25. At this time, the top end of the second spring 51 is in contact with the insert 28, and the bottom end is in contact with the wall surface where the rod opening 30 is located. After installation, the lower end of the rod 27 is aligned with the rod opening 30. When in use, when the second clamping arm 21 is pulled down, the insert 28 applies pressure to the second spring 51, and at the same time, the wall surface where the rod opening 30 is located prevents the second spring 51 from moving down, so that the second spring 51 is compressed. At the same time, the bottom surface of the rod 27 moves away from the rod opening 30. When the rod 27 reaches the bottom wall of the box 2, it is the maximum extent to which the second clamping arm 21 can be pulled open. When the external force is lost, the second spring 51 returns to its original position and generates a thrust, so that the second clamping arm 21 and the upper wall 20 clamp the mobile phone.

[0045] Preferably, the box body 2 is also provided with a locking member that can lock the sliding of the second clamping arm 21. The locking member is provided with a hook 31. The top of the hook 31 is provided with a spring 352 that provides a pushing force, and the top is provided with an inclined surface. The middle part of the hook 31 is rotatably mounted on a cylinder 32 provided inside the box body 2. A button 33 is provided on one side of the bottom of the hook 31. The side wall of the box body 2 is provided with an opening for the button to pop out. The clamping groove 25 is provided with a protrusion 34 that cooperates with the hook 31.

[0046] By adopting the above technical solution, when in use, the user pulls down the second clamping arm 21. During the pulling process, the second spring 51 is compressed, and at the same time, the protrusion 34 will collide with the inclined surface on the hook 31, causing the hook 31 to retract. When the second clamping arm 21 is pulled to the bottom, that is, when the rod 27 reaches the bottom wall of the box 2, the protrusion 34 just leaves the inclined surface of the hook 31 and no longer presses the hook 31. The hook 31 is reset under the self-resetting force of the third spring 52 and is located at the upper end of the protrusion 34, locking the protrusion 34 and restricting the second clamping arm 21 from resetting. At this time, the user can use their fingers to open the horizontal clamping mechanism 7. After opening, the phone is placed in, and the horizontal clamping mechanism 7 resets itself to clamp left and right. Then, the button 33 is pressed to retract the hook 31 and release the protrusion 34. At this time, the second spring 51 is no longer under force and begins to reset itself, carrying the second clamping arm 21 to reset, clamping up and down, so that the phone is accurately located in the middle of the placement area 4.

[0047] Working principle: Through the cooperation of the hook 31 and the protrusion 34, the second clamping arm 21 can be locked in the maximum extended state, so that the longitudinal clamping mechanism 8 can be in the maximum extended state, allowing the user to open the transverse clamping mechanism 7 with both hands. The two first clamping arms 11 that open the transverse clamping mechanism 7 are mirror-distributed, and the toothed channels 15 of both are engaged with the linkage synchronous gear 14 to ensure that the opening and tightening ranges of the two first clamping arms 11 are the same. When the top surface of the mobile phone is pressed against the wall 20, the two first clamping arms 11 move in opposite directions. Tighten the clips at the same rate to ensure that the left and right sides of the phone are equidistant from the sides of the box. The button 33 can force the buckle 31 to retract, so that the hook 31 no longer clamps the protrusion 34, and the second clamping arm 21 is reset. It generates a pushing force from the bottom and forms an upper and lower clamping force with the wall 20, thus fixing the upper and lower side walls of the phone. At this time, the position of the phone is locked. Based on the position of the phone and the coordinates of the column provided by the positioning part 6, the coordinates of the corresponding screen protector for different phones can be calculated in reverse, and screen protectors with corresponding holes can be produced.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
