[0043] Reference Figure 1-6This utility model proposes a manual screen protector applicator for mobile phones, comprising a fixed base assembly 1, a screen protector positioning mechanism 4, a lifting structure 5, a pressure cover 2, and a rolling structure 3. The fixed base assembly 1 includes a fixed base 11 and a mobile phone positioning mechanism 12. The fixed base 11 is provided with a mobile phone mounting slot 111, and the mobile phone positioning mechanism 12 is used to fix the mobile phone. The screen protector positioning mechanism 4 is disposed on the fixed base 11. The lifting structure 5 is disposed on the front end of the fixed base 11. One end of the pressure cover 2 is hinged to the lifting structure 5. The rolling structure 3 includes a sliding base assembly 31 and a rolling roller 32. The rolling roller 32 is detachably connected to the sliding base assembly 31, and the sliding base assembly 31 is slidably connected to the pressure cover 2. The sliding base assembly 31 includes a push-pull handle 311.
[0044] Specifically, the mobile phone is placed in the mobile phone mounting slot 111 and fixed by the mobile phone positioning mechanism 12. The film is fixed by the film positioning mechanism 4. After the pressure cover 2 is placed on top of the mobile phone, the sliding block assembly 31 is driven by pushing the push-pull handle 311, which in turn drives the roller 32, so that the roller 32 presses the film onto the surface of the mobile phone to achieve the mobile phone screen protector application. The pressing pressure is uniform and the screen protector application effect is stable. The lifting structure 5 is used to drive the pressure cover 2 to lift and lower, which can adapt to mobile phones of different thicknesses and solve the problems of low efficiency and unstable screen protector application effect of manual screen protector application.
[0045] In some embodiments, the roller 32 has various types to adapt to different mobile phones. For example, rollers 32 for flat screen and 3D screen mobile phones of different sizes can be adapted to different mobile phones by replacing the corresponding roller 32.
[0046] Furthermore, in some embodiments, the fixed base 11 is provided with an inclined slider guide groove 112 and a slide guide groove 113; the mobile phone positioning mechanism 12 includes a slide 121, a buffer structure 122, a slider 123, a slide guide post 124, a slide push-pull structure 125, and a pad 126; the slide 121 includes a bottom edge and a side edge; the buffer structure 122 is provided on the side edge for abutting the mobile phone; the slider 123 is provided in the slider 123 guide groove 112 and is fixedly connected to the slide 121; the slide guide post 124 is connected to the slide 121 and is movably inserted into the slide guide groove 113; the slide push-pull structure 125 includes a rotating rod 1251 and a stop 1252, the stop 1252 is connected to the slide 121, one end of the rotating rod 1251 is rotatably connected to the slider 123, and the rotating rod 1251 and the stop 1252 are threadedly connected; the pad 126 is fixedly provided above the bottom edge.
[0047] Specifically, rotating the rotary rod 1251 causes it to move relative to the abutment 1252, which in turn drives the slider 123. The slide push-pull structure 125 can drive the slider 123 to move along the slider 123 guide groove 112. The slider 123 drives the slide 121 to move closer to or away from the fixed front and left sides to accommodate different mobile phones. When the slide 121 approaches the mobile phone, the buffer structure 122 first contacts the mobile phone, bringing the mobile phone closer to the side of the mobile phone mounting groove 111. Then, the bottom edge abuts against the front of the mobile phone near the mobile phone mounting groove 111, thus fixing different models of mobile phones. During the movement of the slide 121, the slide guide post 124 guides the slide 121 to move along the slide guide groove 113. The pad 126 is used during the film application process to support the roller 32 and prevent air bubbles from forming when the roller 32 passes behind the mobile phone.
[0048] Furthermore, in some embodiments, the fixed base 11 is provided with a sliding hole 114; the rotating rod 1251 is slidably inserted into the sliding hole 114; the abutment 1252 is rotatably connected to the sliding base 121 and is provided with an open threaded groove, and the rotating rod 1251 can be threadedly connected to the threaded groove.
[0049] Specifically, the abutment 1252 can be flipped. After flipping, it can push the rotating rod 1251, thereby making the slide 121 move faster. When the slide 121 approaches the fixed position of the mobile phone, the abutment 1252 is returned to the fixed seat 11 so that the abutment 1252 is fixed on the fixed seat 11. The rotating rod 1251 engages with the threaded groove. When the rotating rod 1251 is rotated, it can drive the slide 121 to move more forcefully, thereby fixing the mobile phone.
[0050] Furthermore, in some embodiments, the buffer structure 122 includes an abutment piece 1221, a guide post 1222, and a buffer spring 1223; a guide hole extending through the left and right sides is provided on the side, one end of the guide post 1222 is fixedly connected to the abutment piece 1221, the guide post 1222 is slidably inserted into the guide hole, and the buffer spring 1223 is sleeved on the outside of the guide post 1222, with both ends of the buffer spring 1223 abutting against the abutment piece 1221 and the side respectively.
[0051] Specifically, the abutment piece 1221 contacts the mobile phone, the guide post 1222 guides the abutment piece 1221 to move stably along the guide hole, and the buffer spring 1223 plays a buffering role.
[0052] Furthermore, in some embodiments, the left and right sides of the pressure cover 2 are respectively provided with parallel guide strip holes 21; the slide assembly 31 also includes a rotating wheel 312 and a connecting seat 313, the rotating wheel 312 and the connecting seat 313 pass through the guide strip holes 21 and are connected to the push-pull handle 311, and at least one rotating wheel 312 is inserted into each guide strip hole 21; the connecting seat 313 is provided with a slot.
[0053] Specifically, by manually pushing the push-pull handle 311, the push-pull handle 311 drives the rotating wheel 312 and the connecting seat 313 to move along the guide strip hole 21, thereby causing the rolling roller 32 to move, so that the film is squeezed and adhered to the mobile phone by the rolling roller 32; one end of the rotating wheel 312 has a larger radius, forming a stepped shape, and the smaller radius part of the rotating wheel 312 is inserted into the guide strip hole 21. The push-pull handle 311 and the rotating wheel 312 are limited on both sides of the guide strip hole 21, so that the slide assembly 31 moves stably; the connecting seat 313 is provided with a slot for engaging the rolling roller 32.
[0054] Furthermore, in some embodiments, the push-pull handle 311 is arched, with two vertical legs located outside the respective guide strip holes 21.
[0055] Specifically, the arched push-pull handle 311 is located on the outside of the pressure cap 2, making it convenient for the user to apply force to the push-pull handle 311.
[0056] Furthermore, in some embodiments, the lifting structure 5 includes a lifting seat 51 that slides into the fixed seat 11, a threaded rod 52, and an adjusting wheel 53; the threaded rod 52 is fixedly connected to the slide seat 121; the adjusting wheel 53 is inserted into the wheel hole of the slide seat 121, and the adjusting wheel 53 is threadedly connected to the threaded rod 52.
[0057] Specifically, when the adjusting wheel 53 rotates, it moves relative to the threaded rod 52. The threaded rod 52 drives the lifting seat 51 to rise or fall, thereby adjusting the height of the pressure cover 2. The adjusting wheel 53 also plays a role in limiting the up and down movement, preventing the lifting seat 51 from being easily pulled out. In some embodiments, a guide structure is provided to facilitate the stable movement of the lifting seat 51.
[0058] Furthermore, in some embodiments, the membrane positioning mechanism 4 includes a plurality of positioning posts 41, which are respectively disposed on the front and rear sides of the mobile phone mounting slot 111.
[0059] Specifically, the membrane is fixed by inserting positioning posts 41 into holes on the membrane. Each positioning post 41 has a support to prevent the membrane from falling excessively.
[0060] Furthermore, in some embodiments, the front positioning post 41 is lower than the rear positioning post 41.
[0061] Specifically, the front positioning post 41 is lower than the rear positioning post 41, which makes it easier to gradually apply the film to the phone and facilitates the removal of air bubbles during the application process.
[0062] Furthermore, the mobile phone mounting slot 111 includes a clearance slot 1111 for clearing the protruding part of the mobile phone.
[0063] Specifically, the anti-cavity groove 1111 allows the phone to be placed stably, ensuring the screen protector's effectiveness.
[0064] This utility model proposes a manual screen protector applicator for mobile phones. The mobile phone is placed in the mobile phone mounting slot 111 and fixed by the mobile phone positioning mechanism 12. The screen protector is fixed by the screen protector positioning mechanism 4. After the pressure cover 2 is placed on top of the mobile phone, the push-pull handle 311 drives the sliding seat assembly 31, which in turn drives the roller 32, so that the roller 32 presses the screen protector onto the surface of the mobile phone to achieve screen protector application. The pressing pressure is uniform and the screen protector application effect is stable. The lifting structure 5 is used to lift the pressure cover 2, which can be adapted to mobile phones of different thicknesses and solves the problems of low efficiency and unstable screen protector application effect of manual screen protector application.
