[0033] refer to Figures 1 to 7 A pull-out film applicator includes a base plate 1, a cover plate 2, a fixed seat 3, a movable seat 4, and a film assembly 8. The base plate 1 and the cover plate 2 are connected by a connecting plate 11. The fixed seat 3 and the movable seat 4 are mounted on the base plate 1. A positioning groove 5 for placing electronic equipment is formed between the movable seat 4 and the fixed seat 3. The fixed seat 3 is fixed to the base plate 1. The movable seat 4 is movably disposed between the base plate 1 and the fixed seat 3. A guide rail is provided between the movable seat 4 and the fixed seat 3. The distance between the movable seat 4 and the fixed plate is adjusted by the guide rail to adjust the size of the positioning groove 5.

[0034] It should be further explained that the pull-out screen protector in this application embodiment is a general pull-out screen protector. The pull-out screen protector in the attached figure places the mobile phone 9 through the positioning groove 5, and can perform screen protector application for mobile phone 9 screens of 4.7-6.9 inches. In addition, by increasing the size of the positioning groove 5, screen protector application can be performed on tablet computer screens.

[0035] In this embodiment of the application, the pull-out screen protector is used to place the mobile phone 9 through the positioning groove 5. The movable seat 4 can move relative to the fixed seat 3 along the guide rail, thereby adjusting the size of the positioning groove 5 according to the size of the electronic device, so that the pull-out screen protector can be compatible with screen protector application for different electronic devices.

[0036] In order to locate mobile phone 9, in this embodiment, reference is made to...

The pad 52 contacts the back of the electronic device to separate the back of the electronic device from the bottom of the positioning groove 5.

[0039] Understandably, with this setup, the back of the phone 9 has a rear camera. The position and size of the rear camera vary from phone 9 to phone 9. By using the pad 52 to elevate the phone 9, the back of the phone 9 can be prevented from contacting the bottom of the positioning groove 5, thus ensuring that the rear camera on the back of the phone 9 does not interfere with the movement of the movable seat 4.

[0040] To avoid the spacer 52 interfering with the rear camera, in this embodiment, reference is made to... Figure 2 The pad 52 has a clearance 53 located near the rear camera of the electronic device.

[0041] Understandably, with this setup, the rear camera on the back of some phones 9 is positioned close to the corner of the phone 9. This means that when the phone 9 is placed in the positioning slot 5, the rear camera is relatively close to the pad 52. The clearance 53 ensures that the rear camera will not touch the pad 52, so that the four pads 52 only contact the corner of the back of the phone 9, ensuring that the phone 9 can be placed flat in the positioning slot 5.

[0042] In order to fix the membrane assembly 8, in this embodiment, reference is made to Figures 4 to 6 The upper surface of the fixed seat 3 is provided with a first positioning post 31, and the upper surface of the movable seat 4 is provided with a second positioning post 41 and a third positioning post 42. The diameter of the third positioning post 42 is larger than that of the second positioning post 41, forming a foolproof structure.

[0043] Understandably, with this configuration, the film assembly 8 is a pull-out film assembly 8, which is fixed between the cover plate 2 and the fixed base 3 and the movable base 4. The film assembly 8 is fixed by the first positioning post 31, the second positioning post 41 and the third positioning post 42, ensuring that the screen of the pull-out film assembly 8 will not shift position when it is pulled out. The foolproof structure ensures that the film assembly 8 is correctly installed between the fixed base 3 and the movable base 4, reducing the chance of film application errors.

[0044] To achieve the pull-out film application operation, in this embodiment, refer to Figure 4The membrane assembly 8 includes a positioning membrane 81, a screen membrane 82, and a pull-out release membrane 83 connected in sequence. The positioning membrane 81 is provided with a first positioning hole 84, a second positioning hole 85, and a third positioning hole 86. The first positioning hole 84, the second positioning hole 85, and the third positioning hole 86 are respectively engaged with the first positioning post 31, the second positioning post 41, and the third positioning post 42 to position the membrane assembly 8 in the positioning groove 5. The screen membrane 82 matches the screen of the electronic device. During the application process, the pull-out release membrane 83 is located between the screen membrane 82 and the screen of the electronic device. The pull-out release membrane 83 is separated from the screen membrane 82 by pulling, so that the screen membrane 82 contacts and adheres to the screen of the electronic device.

[0045] Understandably, with this setup, after the phone 9 completes its positioning and docking with the positioning slot 5, the positioning film 81 engages with the first positioning post 31, the second positioning post 41, and the third positioning post 42 respectively through the first positioning hole 84, the second positioning hole 85, and the third positioning hole 86, thus completing the positioning of the film assembly 8. Through the foolproof structure, it is ensured that the film assembly 8 is correctly installed on the fixed seat 3 and the movable seat 4. The cover plate 2 covers the film assembly 8, stably clamping the film assembly 8 between the cover plate 2 and the fixed seat 3 and the movable seat 4. Part of the pull-out release film 83 will be exposed to the outside of the cover plate 2. Pulling the pull-out release film 83 outwards separates the pull-out release film 83 from the screen film 82, allowing the screen film 82 to contact and adhere to the screen of the phone 9.

[0046] To ensure that the cover plate 2 clamps the positioning film 81, in this embodiment, refer to Figure 4 and Figure 5 The cover plate 2 is provided with a first slot 21, a second slot 22 and a third slot 23. The first slot 21, the second slot 22 and the third slot 23 are matched with the first positioning post 31, the second positioning post 41 and the third positioning post 42 respectively. The second slot 22 and the third slot 23 are elongated slots and are set along the direction of the guide rail.

[0047] Understandably, with this configuration, the first positioning post 31, the second positioning post 41, and the third positioning post 42 cooperate with the first slot 21, the second slot 22, and the third slot 23, respectively. The first positioning post 31 of the fixed seat 3 will not move. The first positioning post 31 can be stably engaged through the circular first slot 21. The second positioning post 41 and the third positioning post 42 will move with the movable seat 4. The second slot 22 and the third slot 23 are set along the guide rail direction to ensure that the second slot 22 and the third slot 23 can cooperate with the second positioning post 41 and the third positioning post 42 that have moved to different positions, thereby ensuring that the cover plate 2 clamps the positioning film 81.

[0048] To stably guide the movement of the movable seat 4, in this embodiment, reference is made to... Figures 3 to 7The guide rails include a first guide rail 6 and a second guide rail 7 that are parallel to each other. The first guide rail 6 is set at the bottom of the positioning groove 5, and the second guide rail 7 is set on both sides of the positioning groove 5 and located inside the fixed seat 3. The movable seat 4 is provided with a first guide block 61 at the bottom of the positioning groove 5, and the fixed seat 3 is provided with a first guide groove 62. The first guide block 61 is movably set in the first guide groove 62 to form the first guide rail 6. The fixed seat 3 is provided with a second guide groove 72, and the movable seat 4 is provided with a second guide block 71. The second guide block 71 is movably set in the second guide groove 72 to form the second guide rail 7.

[0049] Understandably, with the first guide rail 6 located in the center and the two second guide rails 7 located on both sides, the movable seat 4 can move stably along the guide rails. The first guide rail 6 is set at the bottom of the positioning groove 5, which serves as a guide. The second guide rails 7 are set inside the fixed seat 3, which serves as a guide and limit, preventing the movable seat 4 from becoming loose from the fixed seat 3.

[0050] To prevent the movable seat 4 from becoming loose from the fixed seat 3, in this embodiment, reference is made to... Figure 3 The second guide groove 72 is provided with a guide limiting strip 73 protruding inward, and the second guide block 71 is correspondingly recessed with a limiting groove 74. The guide limiting strip 73 is set parallel to the direction of the second guide groove 72, and the guide limiting strip 73 is locked in the limiting groove 74 to restrict the movement of the second guide block 71 along the guide limiting strip 73.

[0051] Understandably, with this configuration, the inner walls on both sides of the second guide groove 72 are used to restrict the second guide block 71 in the direction of the guide rail, and the guide limit bar 73 restricts the second guide block 71 in the direction perpendicular to the guide rail, thereby restricting the second guide block 71 to move only within the second guide groove 72, preventing the second guide block 71 from detaching from the second guide groove 72, and ensuring a stable connection between the movable seat 4 and the fixed seat 3.

[0052] To guide the mobile phone 9 to align with the positioning slot 5, in this embodiment, reference is made to... Figure 2 The positioning groove 5 has a guide slope 54 on the upper side of the positioning surface 51. The guide slope 54 guides the corner of the electronic device to slide towards the positioning surface 51.

[0053] Understandably, with this setup, the guide slope 54 is tilted toward the positioning surface 51. When the mobile phone 9 is to be placed in the positioning groove 5, the corner of the mobile phone 9 can slide along the guide slope 54 toward the positioning surface 51, helping the mobile phone 9 to align with the positioning groove 5 during the sliding process.

[0054] The working process of the pull-out screen protector of this application is as follows: flip open the cover plate 2, place the mobile phone 9 face up in the positioning groove 5, move the movable seat 4 so that all four positioning surfaces 51 are in contact with the corners of the mobile phone 9 to complete the alignment of the mobile phone 9 with the positioning groove 5, clean the screen of the mobile phone 9 with a wet wipe, a lint-free cloth and a dust removal sticker, align the positioning holes of the film assembly 8 with the positioning posts, close the cover plate 2, pull out the pull-out release film 83, then slide your finger on the screen film 82 at the window 24 so that the screen film 82 automatically adheres to the screen of the mobile phone 9, open the cover plate 2, peel off the positioning film 81 and take out the mobile phone 9 to complete the screen protector application.

[0055] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
