Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone screen protector application, and in particular to a universal screen protector structure with a trapezoidal base for automatic positioning of mobile phones. Background Technology

[0002] Mobile phone screen protectors, also known as mobile phone beautification films or mobile phone protective films, are cold-laminated films used to cover the surface of mobile phone bodies, screens, and other tangible objects. There are many types. Mobile phone screen protectors are not limited to mobile phones; they can also be used to cover MP3 players, MP4 players, computer screens, mice, speakers, and any physical items that need protection. They are named mobile phone screen protectors because they were originally widely used for beautifying mobile phones. Mobile phones covered with screen protectors can look brand new and shiny. They can not only have the effect of refurbishing old phones, but also provide waterproofing and prevent dust from entering the keyboard and screen, thus providing protection.

[0003] Existing screen protector applicator structures for mobile phones can basically meet the usage requirements, but they still have some shortcomings. First, in today's market where orders require quick processing and cost-effectiveness, the previous method of limiting the phone's shape within the applicator meant that each model required a custom applicator, making it unusable. Therefore, different molds needed to be redesigned for different phones, resulting in high costs. Furthermore, there are no products on the market with a one-click automatic positioning structure, which reduces the user experience. Second, current screen protector applicator structures lack a function to adjust the thickness of the phone model. When dealing with phones of different thicknesses, a new applicator needs to be designed, reducing its practicality. Therefore, a universal screen protector applicator structure with a trapezoidal base and automatic phone positioning is needed to meet current market demands. Utility Model Content

[0004] The purpose of this utility model is to provide a universal screen protector structure for automatic positioning of mobile phones with a trapezoidal base, in order to solve the shortcomings of existing screen protectors that require customization for each model, cannot achieve universality, lack a structure that can automatically position with one click, and lack an adjustment function for the thickness of the mobile phone model.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a universal screen protector structure for automatically positioning mobile phones with a trapezoidal base, including a first outer shell, a mobile phone slot, a lens groove, a support platform, a hinge bracket, a fixing plate, a slide groove, an automatic shrinking component, a thickness fine-tuning component, and a roller assembly. The first outer shell is provided with a hinge bracket, and a fixing plate is fixedly connected to the hinge bracket. The fixing plate is embedded inside the support platform. A shrinking plate from the automatic shrinking component is slidably connected to the fixing plate. A first connecting bolt and a second connecting bolt are symmetrically arranged on the shrinking plate. One end of a third spring is connected to the first connecting bolt, and the other end of the third spring is connected to a protrusion at the bottom of the fixing plate. A long toothed rack is sleeved on the second connecting bolt, and one end of the long toothed rack is attached to a limit block. A movable pull is slidably connected to one side of the limit block. The block and the limiting block are slidably connected in the limiting plate. The top of the movable block is attached to the fixed block. The top of the fixed block is connected to one end of the first spring. The fixed block is fixed to the fixed plate by bolts. The other end of the first spring is fixed to the first button. The fixed plate has a sliding groove. The second shell of the thickness fine adjustment component is slidably connected to the sliding groove. The follower head is slidably connected in the through hole on one side of the second shell. The other side of the second shell is fixed to the mobile phone support plate. The follower head is connected to the slider. The slider is connected to one end of the fourth spring. The other end of the fourth spring is fixed to the second shell. The slider is slidably connected to the follower block. The bottom of the follower block is connected to one end of the fifth spring. The other end of the fifth spring is connected to the second shell. The bottom of the second shell is provided with one end of the sixth spring. The other end of the sixth spring is connected to the mobile phone slot.

[0006] Preferably, the roller assembly consists of a handle, a connecting block, a seventh spring, and a roller. Connecting blocks are provided on both sides of the handle, and a seventh spring is provided inside the connecting block. One end of the seventh spring is connected to the roller, and the roller is slidably connected in a groove opened in the connecting block.

[0007] Preferably, the automatic retraction assembly consists of a first button, a first spring, a fixed block, a movable pull block, a limiting block, a second spring, a limiting plate, a long rack, a third spring, a first connecting bolt, a second connecting bolt, a retraction plate, and a damping gear body. A damping gear body is provided on one side of the long rack, and the damping gear body is rotatably connected to the bottom of the fixed plate.

[0008] Preferably, the thickness fine-tuning component consists of a mobile phone support plate, a second button, a follower head, a second shell, a fourth spring, a fifth spring, a sixth spring, a follower block, and a slider. The second button is provided on the top of the follower block and is slidably connected to the second shell.

[0009] Preferably, the fixing plate has a lens groove and a mobile phone groove.

[0010] Preferably, one side of the limiting block is connected to one end of the second spring, and the other end of the second spring is connected to the limiting plate, and the limiting plate is fixed to the bottom of the fixing plate.

[0012] This utility model provides a universal screen protector structure for automatic positioning of mobile phones with a trapezoidal base. Its advantages are as follows: After pressing the first button, the wedge-shaped groove at the bottom of the first button squeezes the movable pull block backward on the fixed block. Then, the wedge-shaped groove on one side of the movable pull block squeezes the limiting block to one side, causing the connection between the protrusion on the limiting block and the long toothed rack to disappear, thus releasing the fixation of the long toothed rack. The long toothed rack slides downward due to the contraction of the third spring on it, thereby causing the contraction plate fixed on the long toothed rack to slide downward. After the phone is placed in the slot and pressed down into the trapezoidal groove, the phone is centered by the trapezoidal groove, thus achieving a centered fixation of the phone. This eliminates the need to customize screen protectors for each phone model when the phone size is different, reducing costs and improving the user experience. The second button controls the tension and contraction of the fourth spring connected to one end of the follower head, achieving the effect of controlling the vertical displacement of the phone support plate on the second shell. When dealing with phones of different thicknesses, the position of the phone support plate can be finely adjusted to control the vertical position of the phone in the slot, improving the practicality of the screen protector.

The fixed block 33 is fixed to the fixing plate 6 by bolts. A first button 31 is fixed to the other end of the first spring 32. A sliding groove 7 is provided on the fixing plate 6. The second outer shell 54 of the thickness fine-tuning component 50 is slidably connected to the sliding groove 7. A follower head 53 is slidably connected in a through hole on one side of the second outer shell 54. A mobile phone support plate 51 is fixed to the other side of the second outer shell 54. The follower head 53 is connected to... On slider 59, one end of the fourth spring 55 is connected, and the other end of the fourth spring 55 is fixed to the second housing 54. Slider 59 is slidably connected to follower block 58. The bottom of follower block 58 is connected to one end of fifth spring 56, and the other end of fifth spring 56 is connected to the second housing 54. One end of sixth spring 57 is provided at the bottom of the second housing 54, and the other end of sixth spring 57 is connected to the mobile phone slot 2. Roller assembly 60 consists of handle 61, connecting block 62, seventh spring 63, and roller 64. Connecting blocks 62 are provided on both sides of handle 61. Seventh spring 63 is provided inside connecting block 62. One end of seventh spring 63 is connected to roller 64. Roller 64 is slidably connected in the groove opened in connecting block 62 and automatically retracts. Component 30 consists of a first button 31, a first spring 32, a fixed block 33, a movable pull block 34, a limiting block 35, a second spring 36, a limiting plate 37, a long rack 38, a third spring 39, a first connecting bolt 40, a second connecting bolt 41, a shrink plate 42, and a damping gear body 43. The damping gear body 43 is located on one side of the long rack 38 and is rotatably connected to the bottom of the fixed plate 6. The thickness fine-tuning component 50 consists of a mobile phone support plate 51, a second button 52, a follower head 53, a second outer shell 54, a fourth spring 55, a fifth spring 56, a sixth spring 57, a follower block 58, and a slider 59. The second button 52 is located on the top of the follower block 58 and is slidably connected to the second outer shell 54.The first button 31 is slidably connected to the through hole in the movable pull block 34. The fixed plate 6 has a lens groove 3, a phone slot 2, and a sliding groove 7. The sliding groove 7 has a U-shaped groove. One side of the limiting block 35 is connected to one end of the second spring 36, and the other end of the second spring 36 is connected to the limiting plate 37. The limiting plate 37 is fixed to the bottom of the fixed plate 6. The fixed plate 6 is provided with a hinge bracket 5, which connects the fixed plate 6 and the first outer shell 1 to form a flip-out structure for the first outer shell 1.

[0027] Specifically, in use, firstly, the first outer casing 1 is opened by rotating the hinge bracket 5 on the fixing plate 6. After placing the mobile phone into the mobile phone slot 2, the first button 31 is pressed. The wedge block 311 at the bottom of the first button 31 will press one end of the movable pull block 34, causing the movable pull block 34 to slide backward. Then, the wedge groove 341 on one side of the other end of the movable pull block 34 will press the limiting block 35 to slide. After sliding, the connection between the protrusion on the limiting block 35 and the long toothed rack 38 disappears, thereby releasing the fixation of the long toothed rack 38. The third spring 39 on the shrink plate 42 fixed on 38 retracts, causing the shrink plate 42 to retract, thereby squeezing the phone towards the trapezoidal base. After the squeezed phone contacts the trapezoidal groove, it slides to the center position due to the symmetrical trapezoidal groove, thus achieving centering and fixing of the phone. This satisfies the requirement of not needing to customize screen protectors for each model when the phone size is different, achieving a common effect. After the phone is centered and fixed, the second button 52 is pressed. The follower block 58 fixed on the second button 52 presses down on the fifth spring 56. At this time, the slider 59 The wedge-shaped groove slides along the wedge-shaped groove on the follower block 58, thereby reducing the potential energy of the fourth spring 55 on the slider 59. When the potential energy is reduced, the follower head 53 can slide up and down along the slide groove 7. When no pressure is applied to the mobile phone support plate 51 on the second housing 54, the sixth spring 57 at the bottom of the second housing 54 will push the second housing 54 upward. When pressure is applied to the mobile phone support plate 51, the second housing 54 will press the sixth spring 57 downward. When fixation is needed, the pressure on the second button 52 is released, thus forming... Adjusting the position of the phone support plate 51 allows for fine-tuning of the phone's vertical position. This eliminates the need to redesign the model when dealing with phones of varying thicknesses, improving the applicator's practicality. After fixing the phone's height and thickness, place the screen protector on the phone, rotate and close the first outer shell 1, hold the handle 61 and roll it downwards until it reaches the bottom, then roll it back to its original position. At this point, open the first outer shell 1, remove the positioning film, push the shrink plate 42 upwards, causing the long toothed strip 38 to slide upwards and be fixed to the limiting block 35 again. The phone can then be removed, and the screen protector application is complete.

[0028] See Figure 4 , Figure 4The screen protector positioning pin 201 consists of two positioning pins, left and right, which are set to correspond to the positioning holes of the screen protector, thereby fixing and positioning the screen protector.
