Technical Field

[0001] This application relates to the technical field of mobile phone screen protectors, and more specifically, to a sliding screen protector applicator. Background Technology

[0002] A screen protector applicator is a tool used to assist in applying screen protectors to a mobile phone screen. Its main purpose is to help users apply the screen protector more accurately and efficiently. It reduces the formation of air bubbles and makes the film adhere to the screen more smoothly.

[0003] In related technologies, screen protector applicators typically include a positioning base for positioning the phone, a positioning component for positioning the protective film, and a pressing component for pressing the protective film onto the phone screen. The positioning component is mounted on the positioning base, allowing the protective film to hang above the phone screen. The pressing component is slidably connected to the positioning base, enabling the sliding downward pressure of various parts of the protective film to press it onto the phone screen. The connection between the positioning base and the pressing component is usually achieved by a groove recessed in the top surface of the positioning base. The pressing component is equipped with a slider that matches the groove. The pressing component moves and presses the film by sliding the slider into the groove. However, dust and other dirt can easily fall into the groove, making it difficult for the slider to slide smoothly. Utility Model Content

[0004] In order to solve the problem in the related technology that the pressure film assembly moves and presses down the protective film by sliding the slider in the groove, and that dust and dirt easily fall into the concave surface of the groove, making it difficult for the slider to slide smoothly, this application provides a sliding film applicator.

[0005] A sliding screen protector applicator includes a positioning base, a crossbeam, a positioning component, and a film assembly. The top surface of the positioning base has a receiving groove adapted to the periphery and size of the mobile phone to which the screen protector is to be applied. The positioning component is disposed on the top surface of the positioning base to position the film assembly so that the film assembly is suspended above the receiving groove. The two sides of the top surface of the positioning base have sliding grooves extending through its thickness, and the length extension direction of the sliding grooves is the same as the length extension direction of the receiving grooves. Both ends of the crossbeam have downwardly extending abutment blocks. The two abutment blocks abut against the opposite sides of the top surface of the positioning base, and the bottom surface of the two abutment blocks is provided with sliders. The width of the sliders matches the width of the sliding grooves, and one slider is inserted into one sliding groove, and the other slider is inserted into the other sliding groove. A film pressing component is provided on the crossbeam to press down the film assembly.

[0006] Preferably, the positioning base is provided with limiting strips extending along the length of the slide groove on its opposite side walls, and both abutment blocks are provided with downwardly extending limiting side plates on their bottom surfaces. The inner surfaces of both limiting side plates are provided with limiting blocks. One limiting side plate abuts against one side of one limiting strip and the limiting block provided on the limiting side plate abuts against the bottom side of the limiting strip. The other limiting side plate abuts against one side of the other limiting strip and the limiting block provided on the limiting side plate abuts against the bottom side of the limiting strip.

[0007] Preferably, the positioning base is provided with a plurality of connecting bridges in both of the sliding grooves, the plurality of connecting bridges are arranged at intervals along the length extension direction of the sliding grooves, and the plurality of connecting bridges are integrally formed with the positioning base.

[0008] Preferably, the pressing component is a pressing roller, one end of which is rotatably connected to one of the abutting blocks, and the other end of which is rotatably connected to another abutting block.

[0009] Preferably, the positioning component includes a support frame and a pad, the support frame and the pad are fixed to the top surface of the positioning base, and the support frame and the pad are respectively placed on opposite sides of the length extension direction of the receiving groove. A first positioning post is provided on the top of the support frame, and a second positioning post is provided on the top of the pad. The membrane component includes a positioning membrane and a UTG membrane. The UTG membrane is bonded to the positioning membrane with AB glue. The UTG membrane is located in the middle of the positioning membrane. A first positioning hole matching the first positioning post and a second positioning hole matching the second positioning post are respectively opened at both ends of the positioning membrane.

[0010] Preferably, the height of the first positioning post relative to the top surface of the positioning base is higher than the height of the second positioning post relative to the top surface of the positioning base.

[0011] Preferably, the support frame includes a crossbar with both ends bent downwards to form connecting portions. The two connecting portions are connected and fixed to the positioning base. There is a gap between the crossbar and the top surface of the positioning base. The first positioning post is disposed on the top of the crossbar. The membrane assembly also includes a release film and a handle film. The release film matches the size of the UTG film and is attached to the side of the UTG film away from the positioning film. The handle film is connected to the end of the release film near the second positioning hole, and the handle film is bent downwards and extends in the direction of the first positioning hole. The gap between the crossbar and the top surface of the positioning base is used for the handle film to pass through.

[0012] The beneficial technical effects of this application are as follows: By setting the thickness of the slide groove to penetrate the positioning base, when dust and dirt fall into the slide groove, they fall out of the slide groove and are not easy to accumulate on the slide groove. This makes the slider slide smoothly when the crossbeam is pushed to move. The height of the positioning pressing component is determined by the abutting part abutting against the top surface of the positioning base. This makes it easier to make the pressure of the pressing component on the membrane assembly uniform when it moves with the crossbeam, so that the membrane assembly adheres better to the mobile phone screen.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Reference Figure 1 and Figure 2A sliding screen protector applicator includes a positioning base 1, a crossbeam 2, a positioning component 3, and a film component 4. The top surface of the positioning base 1 has a receiving groove 11 adapted to the periphery and size of the mobile phone to be covered. The mobile phone is placed in the receiving groove 11 to position and fix it, with the screen facing upwards. The positioning component 3 is located on the top surface of the positioning base 1 to position the film component 4, suspending it above the receiving groove 11. The two sides of the top surface of the positioning base 1 have sliding grooves 12 extending through its thickness. The length extension direction of the sliding grooves 12 is the same as that of the receiving grooves 11. Both ends of the crossbeam 2 have downward-extending abutment blocks 21, which abut against opposite sides of the top surface of the positioning base 1. The bottom surface of each abutment block 21 has a slider 22, the width of which matches the width of the sliding groove 12. One slider 22 engages in one sliding groove 12, and the other slider 22 engages in the other sliding groove 12. Inside, the slider 22 slides within the groove 12, allowing the entire crossbeam 2 to slide along the length of the groove 12. By setting the groove 12 to be thick enough to penetrate the positioning base 1, dust and other dirt falling into the groove 12 will fall out of the groove 12, preventing them from accumulating on it. This makes the slider 22 slide smoothly and the entire crossbeam 2 slide smoothly. A pressure roller 23 is provided on the crossbeam 2. The pressure roller is made of elastic rubber. One end of the pressure roller is rotatably connected to a contact block 21, and the other end of the pressure roller is rotatably connected to another contact block 21. The movement of the crossbeam 2 drives the pressure roller to move. The contact block abuts against the top surface of the positioning base 1 to position the height of the pressure roller. The distance between the pressure roller and the mobile phone screen is set to be slightly less than the thickness of the film assembly 4. This allows the pressure roller to press the film assembly 4 onto the mobile phone screen, resulting in a better effect of the film assembly 4 being evenly pressed and adhered to the mobile phone screen.

[0019] Reference Figure 1 and Figure 2 Furthermore, the positioning base 1 is provided with limiting strips 13 extending along the length of the slide groove 12 on its opposite side walls. The bottom surfaces of the two abutting blocks 21 are provided with downwardly extending limiting side plates 211. The inner surfaces of the two limiting side plates 211 are provided with limiting blocks 2111. One limiting side plate 211 abuts against one side of a limiting strip 13 and the limiting block 2111 provided on the limiting side plate 211 abuts against the bottom side of the limiting strip 13. The other limiting side plate 211 abuts against one side of another limiting strip 13 and the limiting block 2111 provided on the limiting side plate 211 abuts against the bottom side of the limiting strip 13. The limiting block 2111 cooperates with the limiting strip 13 to enable the limiting beam 2 to move in the vertical direction, thereby avoiding the situation where the beam 2 swings during the process of manually pushing the beam 2 to move, causing uneven force on the film assembly 4 by the pressure roller.

[0020] Reference Figure 1Furthermore, the positioning base 1 is provided with several connecting bridges 14 in both slides 12. The connecting bridges 14 are arranged at intervals along the length of the slides 12 and are integrally formed with the positioning base 1. Since the slides 12 are located at the edge of the positioning base 1, the connecting bridges 14 enhance the structural strength of the positioning base 1. This prevents the edges of the positioning base 1 from deforming when the pushing beam 2 moves and applies force to the positioning base 1, thus preventing the slides 12 from deforming and causing the slider 22 to slide unevenly. The spacing between the connecting bridges 14 in each slide 12 is greater than 0.5 cm, and the thickness of the connecting bridges 14 is less than 0.2 mm, making it less likely for dust and dirt to accumulate on the connecting bridges 14.

[0021] Reference Figure 1 Furthermore, the positioning component 3 includes a support frame 31 and a pad 32, both of which are fixed to the top surface of the positioning base 1. The support frame 31 and the pad 32 are positioned on opposite sides of the length extension direction of the receiving groove 11. The top of the support frame 31 is provided with a first positioning post 311, and there are three first positioning posts 311. The three first positioning posts 311 are arranged at intervals along the width extension direction of the receiving groove 11. The top of the pad 32 is provided with a second positioning post 321, which is located at the position of the most central first positioning post 311. The membrane component 4 includes a positioning membrane 41 and a UTG membrane 42. The UTG membrane 42 is attached to the positioning membrane 41 with AB glue and is located in the middle of the positioning membrane 41. In the production process, the UTG film 42 is positioned and bonded to the positioning film 41. The positioning film 41 is a flexible PET film. Both ends of the positioning film 41 have a first positioning hole 411 that matches the first positioning post 311 and a second positioning hole 412 that matches the second positioning post 321. There are three first positioning holes 411. The positioning film 41 is fitted onto the first positioning post 311 through the first positioning hole 411 and onto the second positioning post 321 through the second positioning hole 412. The positioning film 41 is limited by the first positioning post 311 and the second positioning post 321, and the positioning film 41 is supported by the support frame and the pad 32 to achieve the positioning and fixation of the positioning film 41, thereby aligning the UTG film 42 with the mobile phone screen and suspending it above the mobile phone screen.

[0022] Reference Figure 1 Furthermore, the side of the pad 32 away from the receiving groove 11 is an inclined surface 322 that is inclined upward from the top surface of the positioning base 1. This inclined surface 322 is configured to facilitate the movement of the pressure roller over the pad 32 and press it onto the membrane assembly 4.

[0023] Reference Figure 1 and Figure 3Furthermore, the height of the first positioning post 311 relative to the top surface of the positioning base 1 is higher than the height of the second positioning post 321 relative to the top surface of the positioning base 1, so that the film assembly 4 is set at an angle, so that the end of the UTG film 42 near the first positioning post 311 is away from the mobile phone screen, and the end of the UTG film 42 near the second positioning post 321 is close to the mobile phone screen. When the crossbeam 2 moves to make the pressure roller press the film assembly 4, the UTG film 42 is pressed down from the end of the UTG film 42 close to the mobile phone screen, so that the UTG film 42 is gradually pressed onto the mobile phone screen instead of being pressed at once. This helps to reduce the generation of air bubbles and makes the film application effect better.

[0024] Reference Figure 1 and Figure 3 Furthermore, the membrane assembly 4 also includes a release film 43 and a handle film 44. The release film 43 matches the size of the UTG film 42 and is attached to the side of the UTG film 42 away from the positioning film 41. The release film 43 protects the UTG film 42 from dirt and prevents it from affecting the film application effect. The handle film 44 is connected to the end of the release film 43 near the second positioning hole 412 and is bent downwards and extends towards the first positioning hole 411, making it easy to tear the release film 43 from the UTG film 42 by pulling the end of the handle film 44 away from the release film 43. The support frame 31 is then wrapped. The crossbar 312 has two ends bent downwards to form connecting parts 313. The two connecting parts 313 are connected and fixed to the positioning base 1. There is a gap between the crossbar 312 and the top surface of the positioning base 1. When the film assembly 4 is fixed by the first positioning post 311 and the second positioning post 321, the handle film 44 is pushed out through the gap between the crossbar 312 and the top surface of the positioning base 1. This makes it easier to pull the handle film 44 to tear the release film 43 off the UTG film 42 during the process of pressing the film assembly 4 by the pressure roller, thereby reducing the situation of dust and dirt on the UTG film 42 during the film application process.
