Description

Technical Field

[0001] This utility model belongs to the technical field of mobile phone screen protector devices, specifically relating to an auxiliary structure for applying screen protectors to mobile phones. Background Technology

[0002] Electronic products have become increasingly integrated into consumers' lives, especially mobile phones and tablets. As consumers take better care of their electronic products and develop a stronger awareness of protection, they often apply screen protectors to their mobile phones and tablets to prevent scratches or damage from drops.

[0003] Currently, consumers typically purchase screen protectors themselves and then apply them to the screen by visually aligning them or by using the accessory kit included with the screen protector.

[0004] Visual alignment is less accurate, often requiring multiple attempts in actual operation, which can easily lead to wasted screen protector. The auxiliary kit included with the screen protector can help with application, but its connection to the phone is unstable, making it inconvenient to operate and unsuitable for different brands and models of phones.

[0005] A search revealed that Chinese utility model patent CN222947083U discloses a "film applicator with an auxiliary positioning structure", which includes a base and a positioning seat slidably disposed on the base. The base has a first platform and a second platform. The positioning seat is slidably disposed on the second platform. A first positioning platform is protruding from the end of the first platform away from the second platform. A first positioning post is protruding from the upper surface of the first positioning platform. The first positioning post is used to position one end of the mobile phone film. A positioning plug for positioning the mobile phone is protruding from the side of the first positioning platform facing the positioning seat.

[0006] Existing screen protector devices, including those mentioned above, can meet general usage needs, but they only clamp the phone from both ends, resulting in poor stability and clamping position accuracy. They also make it difficult to accurately position the screen protector. In addition, the charging port locations and hole shapes vary among different phones, making the positioning plugs non-universal.

[0007] To address the aforementioned issues, this application proposes an auxiliary structure for applying screen protectors to mobile phones. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: an auxiliary structure for applying a screen protector to a mobile phone, including a placement platform 1, with a clearance groove 11 for avoiding the mobile phone camera at one end of the top surface of the placement platform 1, and further including: a fixed positioning block 2 fixed to the other end of the top surface of the placement platform 1, two symmetrically distributed clamping blocks 3 movably installed on the top surface of the placement platform 1, a distance adjustment component 4 for adjusting the distance between the two clamping blocks 3, a movable positioning block 5 movably disposed in the clearance groove 11; and an adjustment mechanism 6 for adjusting the distance between the movable positioning block 5 and the fixed positioning block 2. With the above solution, when using, the mobile phone to be covered is first placed on the top surface of the placement platform 1, so that the mobile phone camera is aligned with the clearance groove 11 and embedded therein. The setting of the clearance groove 11 can effectively prevent the camera from being damaged by squeezing, and at the same time provide an initial positioning reference for the mobile phone, preventing the mobile phone from tilting.

[0023] After the phone is placed, one end is fixed and positioned against the fixed positioning block 2 to achieve fixed positioning of that end. For phones of different widths, the distance between the two clamping blocks 3 can be adjusted by the distance adjustment component 4. When the distance adjustment component 4 is working, it drives the two clamping blocks 3 to move towards or away from each other along the top surface of the placement platform 1 until the two clamping blocks 3 are tightly attached to the two side frames of the phone, thereby clamping and fixing the phone from both sides to adapt to the width differences of different phone models.

[0024] Next, for phones of different lengths, the distance between the movable positioning block 5 and the fixed positioning block 2 is adjusted using the adjustment mechanism 6. When the adjustment mechanism 6 is in operation, it drives the movable positioning block 5 to move along the length of the phone in the clearance groove 11 until the movable positioning block 5 is pressed against the end of the phone near the camera. Together with the fixed positioning block 2, the phone is limited from both the front and rear ends to ensure that the phone is accurately and stably positioned on the placement platform 1.

[0025] Throughout the entire phone fixing process, the coordinated action of the distance adjustment component 4 and the adjustment mechanism 6 enables rapid positioning and clamping of phones of different sizes, forming a three-dimensional (left and right, front and back) limiting structure for the phone. At this time, the position of the phone on the placement platform 1 is precisely fixed, providing a stable reference surface for subsequent screen protector application.

[0026] Operators can easily and accurately apply the screen protector by simply aligning it with the reference position determined by the auxiliary structure. This effectively avoids problems such as screen protector misalignment and bubbles caused by the phone's position deviation, significantly improving the efficiency and quality of screen protector application.

[0027] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the distance adjustment component 4 includes: a first guide slider 41 fixed to the bottom end of the clamping block 3, a bidirectional threaded rod 42 rotatably installed in the first guide groove 12, and a first handle 43 fixed to the protruding end of the bidirectional threaded rod 42. The top of the placement platform 1 is provided with a first guide groove 12 that is adapted to the first guide slider 41. One end of the bidirectional threaded rod 42 extends out of the placement platform 1, and the first guide slider 41 and the bidirectional threaded rod 42 are threadedly engaged. With the above solution, when it is necessary to adjust the distance between the two clamping blocks 3, the operator drives the bidirectional threaded rod 42 to rotate by rotating the first handle 43.

[0028] Since the threads at both ends of the bidirectional threaded rod 42 have opposite directions of rotation, and the first guide sliders 41 at the bottom of the two clamping blocks 3 are respectively threaded with the two ends of the bidirectional threaded rod 42, when the bidirectional threaded rod 42 rotates, the two first guide sliders 41 will move synchronously towards or away from each other along the first guide groove 12.

[0029] The groove structure of the first guide slide 12 limits the first guide slider 41, ensuring that the clamping block 3 can only move in a straight line along the width of the mobile phone, avoiding deviation or shaking.

[0030] As the distance between the two clamping blocks 3 changes, it can adapt to mobile phone bodies of different widths: when the phone is narrow, rotate the first handle 43 in the forward direction to bring the clamping blocks 3 closer to each other; when the phone is wide, rotate the first handle 43 in the reverse direction to move the clamping blocks 3 away from each other, until the inner sidewalls of the clamping blocks 3 on both sides are tightly fitted with the phone frame.

[0031] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the distance adjustment component 4 further includes a first guide rod 44 fixed in the first guide groove 12 and passing through the first guide slider 41. With the above solution, when in use, the first guide rod 44 is used to limit the movement direction of the first guide slider 41, which further improves the stability of the first guide slider 41, thereby improving the stability of the clamping block 3.

[0032] Preferably, by Figure 1As shown, in this embodiment, it also includes a rubber pad 31 fixed to the clamping surface of the clamping block 3. With the above solution, the rubber pad 31 has flexibility and anti-slip properties during use. The clamping block 3 flexibly clamps the two sides of the mobile phone frame through the rubber pad 31, avoiding the problem of accidental scratches on the two sides of the mobile phone frame caused by rigid clamping, thus improving safety.

[0033] It is easy to understand that rubber pads 31 are also provided on the clamping surfaces of the fixed positioning block 2 and the movable positioning block 5.

[0034] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the adjustment mechanism 6 includes: a second guide slider 61 fixed to the bottom of the movable positioning block 5, a threaded rod 62 rotatably installed in the second guide groove 13, and a second handle 63 fixed to the protruding end of the threaded rod 62. The top of the placement platform 1 is provided with a second guide groove 13 that is adapted to the second guide slider 61. One end of the threaded rod 62 extends out of the placement platform 1, and the second guide slider 61 and the threaded rod 62 are threadedly engaged. With the above scheme, when it is necessary to adjust the distance between the movable positioning block 5 and the fixed positioning block 2, the operator drives the threaded rod 62 to rotate by rotating the second handle 63.

[0035] The threaded screw 62 adopts a one-way thread design and forms a threaded transmission engagement with the internal threaded hole at the bottom of the second guide slider 61. Since the second guide groove 13 forms a lateral limit on the second guide slider 61, when the threaded screw 62 rotates, the second guide slider 61 can only move in a straight line along the extension direction of the second guide groove 13 (i.e., the length direction of the mobile phone), thereby driving the movable positioning block 5 to move synchronously.

[0036] The operator can rotate the second handle 63 clockwise or counterclockwise according to the actual length of the mobile phone: if the mobile phone is long, the movable positioning block 5 needs to be moved away from the fixed positioning block 2. At this time, the second handle 63 is rotated in the opposite direction to make the threaded screw 62 rotate, which drives the second guide slider 61 to move outward along the second guide groove 13; if the mobile phone is short, the second handle 63 is rotated in the forward direction to make the second guide slider 61 move inward.

[0037] When the end face of the movable positioning block 5 is in close contact with the frame of the mobile phone camera, the rotation of the second handle 63 stops. At this time, the movable positioning block 5 and the fixed positioning block 2 form positioning constraints from the front and rear ends of the mobile phone respectively. Together with the clamping blocks 3 on both sides, the mobile phone is accurately positioned in four directions (left, right, front, and back).

[0038] Preferably, by Figure 1 and Figure 3As shown, in this embodiment, the adjustment mechanism 6 further includes a second guide rod 64 fixed in the second guide groove 13 and passing through the second guide slider 61. With the above solution, when in use, the second guide rod 64 is used to limit the movement direction of the second guide slider 61, which further improves the stability of the second guide slider 61, thereby enhancing the stability of the movable positioning block 5.

[0039] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes an anti-slip mechanism 7, which includes a rubber anti-slip pad 71. An installation groove 14 is provided on the top of the placement platform 1. The rubber anti-slip pad 71 is disposed in the installation groove 14, and anti-slip protrusions 711 are evenly distributed on the top surface of the rubber anti-slip pad 71. With the above solution, when the mobile phone is placed on the top surface of the placement platform 1, its bottom surface directly contacts the top surface of the rubber anti-slip pad 71.

[0040] The rubber anti-slip pad 71 is embedded into the top of the placement platform 1 through the mounting groove 14. The depth design of the mounting groove 14 makes the top surface of the rubber anti-slip pad 71 slightly higher than (or flush with) the surface of the placement platform 1, ensuring that the bottom surface of the mobile phone is fully in contact with the rubber anti-slip pad 71.

[0041] The anti-slip protrusion 711 further increases the coefficient of friction by increasing the roughness of the contact surface, thereby further improving the stability of the phone during the screen protector application process.

[0042] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes: a first magnetic strip 72 fixed to the bottom surface of the rubber anti-slip mat 71 and a second magnetic strip 73 fixed in the mounting groove 14. The second magnetic strip 73 and the first magnetic strip 72 are magnetically attracted to each other. With the above solution, the magnetic installation can quickly position the installation position of the rubber anti-slip mat 71 during use without manual positioning. In addition, the magnetic installation ensures the installation stability of the rubber anti-slip mat 71 and also facilitates its disassembly and replacement.

[0043] Components not described in detail in this article are existing technologies.

[0044] The working principle and usage process of this utility model: When using the auxiliary structure of this utility model, first place the mobile phone to be covered on the top surface of the placement platform 1, so that the mobile phone camera is aligned with the avoidance groove 11 and embedded therein. The setting of the avoidance groove 11 can effectively prevent the camera from being damaged by squeezing, and at the same time provide an initial positioning reference for the mobile phone to prevent the mobile phone from tilting. After the phone is placed, one end is fixed and positioned against the fixed positioning block 2 to achieve fixed positioning of that end. For phones of different widths, the distance between the two clamping blocks 3 can be adjusted by the distance adjustment component 4. When the distance adjustment component 4 is working, it drives the two clamping blocks 3 to move towards or away from each other along the top surface of the placement platform 1 until the two clamping blocks 3 are tightly attached to the two side frames of the phone, thereby clamping and fixing the phone from both sides to adapt to the width differences of different phone models. Next, for phones of different lengths, the distance between the movable positioning block 5 and the fixed positioning block 2 is adjusted using the adjustment mechanism 6. When the adjustment mechanism 6 is in operation, it drives the movable positioning block 5 to move along the length of the phone in the clearance groove 11 until the movable positioning block 5 is pressed against the end of the phone near the camera. Together with the fixed positioning block 2, the phone is limited from both the front and rear ends to ensure that the phone is accurately and stably positioned on the placement platform 1. During the entire process of fixing the mobile phone, the coordinated action of the distance adjustment component 4 and the adjustment mechanism 6 enables the rapid positioning and clamping of mobile phones of different sizes, forming a three-dimensional (left and right, front and back) limiting structure for the mobile phone. At this time, the position of the mobile phone on the placement platform 1 is precisely fixed, providing a stable reference surface for the subsequent screen protector application operation. Operators can easily and accurately apply the screen protector by simply aligning it with the reference position determined by the auxiliary structure. This effectively avoids problems such as screen protector misalignment and bubbles caused by the phone's position deviation, significantly improving the efficiency and quality of screen protector application.
