[0035] Reference Figures 1-3The utility model provides a kind of mobile phone film applicator, including base 1, guide rail type installation in the top of base 1 slider 2 and install on the roller 19 of slider 2, the central portion of base 1 is equipped with the containing bin 3 of fixed film equipment to be pasted, containing bin 3 is provided with cotton 4 around, mobile phone 35 is protected, and by replacing cotton 4 can adapt to the film of different size mobile phone 35 or tablet computer and so on electronic equipment, the head and tail of base 1 are provided with the positioning structure for fixing film component 36, positioning structure includes the positioning hook 8 of being set to the head of base 1 and the positioning column 7 of being set to the tail of base 1, the tail of base 1 is equipped with the movable support block 5 of sliding, movable support block 5 is connected by elastic member and the hook on base 1, cantilever 6 is equipped on movable support block 5.

[0036] In film, refer to Figure 13 , mobile phone 35 is placed in containing bin 3, then film component 36 is fixed on the positioning hook 8 and positioning column 7 of the head and tail of base 1, at this moment, elastic member is in natural state, so that cantilever 6 on movable support block 5 is located above the tail of mobile phone 35 and below film component 36, the dustproof film of film component 36 is pulled down, slider 2 drives roller 19 to move from the head to the tail of base 1, slowly paste tempered film on mobile phone 35, when slider 2 moves to the tail of base 1, it will push movable support block 5 to move, so that cantilever 6 exits from between tempered film and mobile phone 35, so that the tail of tempered film is pasted on the tail of mobile phone 35, and film work is completed.

[0037] In the embodiment, refer to Figures 1-4 , the first gap 14 is provided with the first gap 14 in the end close to the head of base 1, and the second gap 12 is provided with the second gap 12 in the end close to the tail of base 1, the slider 2 can be mounted on the guide rail 16 from the first gap 14, and then can be removed from the second gap 12 when sliding to the tail of base 1.

[0038] In some embodiments, refer to Figure 5 And Figures 10-12 , the guide rail 16 on both sides of the top of base 1 includes circular arc guide rail surface 17 on top and horizontal guide rail surface 18 on bottom, the horizontal guide rail surface 18 is located on the outside of base 1, both ends of the slider 2 are provided with circular arc sliding groove 20 and limit block, to correspond to the two guide rails 16 on the top of base 1, the top of limit block is provided with arc sliding surface 25, when the slider 2 slides on the guide rail 16, the circular arc guide rail surface 17 is connected with circular arc sliding groove 20 slidingly, or the horizontal guide rail surface 18 is connected with the arc sliding surface 25 slidingly, so as to realize the double-track application of guide rail 16.

[0039] It can be understood that, in normal circumstances, the slider 2 is pushed to move under the downward pressure, so that the roller 19 has sufficient pressure on the film assembly 36, so as to paste the tempered film on the screen of the mobile phone 35 without bubbles, at this time, the circular arc sliding groove 20 on the slider 2 is in contact with the circular arc guide surface 17 on the top of the guide rail 16, and the arc sliding surface 25 on the limiting block is not in contact with the horizontal guide surface 18 on the bottom of the guide rail 16, compared with the existing rectangular cross-section guide rail 16 used by the existing film pasting device, the contact area is reduced, and the sliding of the slider 2 is more smooth. In the case that the height of the mobile phone 35 is relatively high, the user can give an upward force to the slider 2, so that the arc sliding surface 25 on the limiting block is in contact with the horizontal guide surface 18 on the bottom of the guide rail 16, at this time, the circular arc sliding groove 20 on the slider 2 is not in contact with the circular arc guide surface 17 on the top of the guide rail 16, so that the slider 2 is pushed to move the roller 19 to paste the tempered film on the screen of the mobile phone 35 in the case that the height of the mobile phone 35 is relatively high, and the contact area between the limiting block and the guide rail 16 is smaller, so that the sliding of the slider 2 is more smooth.

[0040] In the embodiment, referring to Figure 6 , the guide rail 16 at the first gap 14 has a first residual step 28, the surface 29 of the first residual step 28 is inclined outward from top to bottom, the limiting block is arranged on the extension arm 26 of the circular arc sliding groove 20, the extension arm 26 has elasticity and can move the limiting block to the bottom of the first residual step 28, at this time, the bottom of the first residual step 28 blocks the upward movement of the limiting block.

[0041] It can be understood that, when the slider 2 is installed, the limiting blocks at both ends of the slider 2 are in contact with the surfaces 29 of the first residual steps 28 on both sides of the base 1, then when the slider 2 moves downward, the limiting blocks gradually move downward on the first residual steps 28 due to the elasticity of the extension arm 26, and when the limiting blocks exceed the first residual steps 28, the limiting blocks reset under the elastic force of the extension arm 26, at this time, the bottom of the first residual step 28 blocks the upward movement of the limiting block, thereby completing the installation of the slider 2 and enabling the slider 2 to stably slide on the guide rail 16 without falling out of the first gap 14.

[0042] Further, referring to Figure 7 , Figures 11-12 , the limiting blocks at both ends of the slider 2 are both two, and the two limiting blocks can share the pressure of the slider 2 and the guide rail 16, so that the sliding of the slider 2 on the guide rail 16 is more stable. Among them, the two limiting blocks at the same end of the slider 2 are a long limiting block 22 and a short limiting block 21, the length of the short limiting block 21 is less than the length of the long limiting block 22, the short limiting block 21 is close to the head side of the base 1, and the long limiting block 22 is close to the tail side of the base 1, referring to Figure 7a, the guide rail 16 at the second gap 12 has a second residual step 30, the second step is provided with a third gap 13 for the long limiting block 22 to pass near the tail side of the base 1. In this way, when the long limiting block 22 is completely moved to the third gap 13, the slider 2 can be removed from the second gap 12. If the second gap 12 can also make the long limiting block 22 pass, the front end of the slider 2 will be raised when the slider 2 is not moved to the tail of the base 1 to complete the film, thereby affecting the film effect. Therefore, through the setting of the third gap 13, when the slider 2 has not been moved to the tail of the base 1 to complete the film, the long limiting block 22 is blocked by the second residual step 30, so that the front end of the slider 2 will not be raised, thereby ensuring the film effect.

[0043] In some embodiments, referring to Figure 7 b, the second residual step 30 is inwardly inclined from one end near the head of the base 1 to one end near the tail of the base 1, which can reduce the blocking effect of the second residual step 30 on the limiting block, thereby facilitating the convenience of removing the slider 2 from the second gap 12.

[0044] In some other embodiments, referring to Figure 7 c, a fourth gap 31 for the short limiting block 21 to pass can be provided near the head side of the base 1 at the second step, and the length of the fourth gap 31 is less than the length of the long limiting block 22, that is, the long limiting block 22 will not come out of the fourth gap 31 when moving on the guide rail 16. In this way, when the slider 2 has not been moved to the tail of the base 1 to complete the film, the long limiting block 22 is located at the third gap 13 and the short limiting block 21 is located at the fourth gap 31, neither of which is blocked, thereby easily removing the slider 2 from the base 1.

[0045] In the present embodiment, referring to Figures 2-4 , the horizontal guide rail surface 18 at the bottom of the guide rail 16 is provided with a groove portion 15 near the side of the first gap 14, and the slider 2 can be more smoothly slid onto the guide rail 16 through the groove portion 15 after being installed at the first gap 14.

[0046] In the present embodiment, referring to Figure 8 , the bottom surface of the accommodating bin 3 is upwardly inclined from the head to the tail of the base 1, so that the height of the screen of the mobile phone 35 gradually increases in the direction of movement of the roller 19 during the film pasting, and the pressure component applied by the roller 19 during the film pasting is increased, thereby effectively discharging air and improving the film pasting effect and preventing the generation of air bubbles. Further, the inclination angle of the bottom surface of the accommodating bin 3 is 0.2-1°, preferably 0.33°, so that the film pasting effect is improved while the stability and smoothness of the sliding of the slider 2 are ensured.

[0047] In the present embodiment, referring toFigure 10 And Figure 11 The inner side of the sliding block 2 has a mounting space for accommodating the roller 19, and the inner wall of the sliding block 2 is provided with two mounting blocks 23, which are correspondingly provided with mounting grooves 24, and the two ends of the central rotating shaft 27 of the roller 19 are clamped in the two mounting grooves 24 respectively, so that the central rotating shaft 27 of the roller 19 can be directly pressed into the mounting groove 24 during mounting of the roller 19, thereby improving the convenience of mounting the roller 19.

[0048] Further, referring to Figure 12 The mounting groove 24 comprises a straight groove 32 and a rotating groove 34, and the two sides of the connection between the straight groove 32 and the rotating groove 34 are provided with arc-shaped protrusions 33, and a limiting opening is formed between the two arc-shaped protrusions 33. The central rotating shaft 27 at both ends of the roller 19 is rotatably connected in the rotating groove 34 after passing through the straight groove 32 and the limiting opening, wherein the width of the limiting opening is less than or equal to the diameter of the central rotating shaft 27. It can be understood that the central rotating shaft 27 enters from the straight groove 32, and is then limited at the limiting opening. At this time, the central rotating shaft 27 needs to be pressed from the limiting opening into the rotating groove 34, and then the central rotating shaft 27 rotates in the rotating groove 34 to realize the function of the roller 19. Such an installation method is simple and labor-saving. At the same time, due to the limiting of the limiting opening, the roller 19 will not fall out of the rotating groove 34 without external force, thereby improving the assembly stability of the sliding block 2 and the roller 19.

[0049] In the embodiment, the handle 9 is formed at the tail of the base 1, the protrusions 10 are arranged on both sides of the handle 9, and the clamping space 11 for accommodating fingers is formed between the protrusions 10 and the base 1. When pasting the film, two fingers (generally the thumb and the index finger) of the user are respectively placed in the clamping space 11 on both sides of the handle 9, and then the handle 9 is clamped, so that the base 1 is fixed, and the other hand of the user can push the sliding block 2 to complete the film pasting work. The clamping space 11 does not interfere with the movement of the movable supporting block 5, so that the sliding block 2 does not hit the fingers when pushing the movable supporting block 5 to move, and the problem of pinching the hand does not occur.

[0050] The above is a specific description of the preferred embodiment of the utility model, but the utility model is not limited to the above-mentioned embodiment.
