[0002] With the continuous development of science and technology, electronic technology is becoming more and more mature, and there are more and more electronic devices. For electronic devices with large screens, such as mobile phones, in order to prevent the screen from being scratched by friction with other objects during use, or to prevent the mobile phone from being accidentally dropped and directly breaking the screen during use, it is usually necessary to stick a layer of protective film on the mobile phone screen. The existing mobile phone film is generally applied manually, which is not only inefficient but also has a poor film application effect. In addition, manual film application without the help of tools is also prone to increase the scrap rate of the protective film during the film application process. Therefore, people later invented a mobile phone film applicator to assist manual film application. The film applicator is actually a mobile phone clamping device with a depth higher than the mobile phone body. After the mobile phone is clamped on the film applicator, the protective film can be simply placed along the retaining edges around the mobile phone to complete the film application.
[0003] However, the film applicators on the market are all dedicated film applicators, or are used for a certain series or a certain brand of mobile phone film applicators, and cannot be universally used for all mobile phones, which greatly increases production costs and consumption.

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0026] See also Figure 1 and Figure 2The present embodiment provides a portable universal mobile phone film applicator, comprising a main body 10 having a receiving cavity 11 for accommodating a mobile phone, two positioning posts 12 for positioning a film are formed at the rear of the main body 10; a film applicator 20 which can slide repeatedly along a first direction and is used to press the film and stick the film to the mobile phone is installed on the main body 10, and a conical roller 21 and a straight roller 22 are installed on the film applicator 20; a paddle 13 for preventing bubbles from being generated at the rear of the mobile phone when the film is applied is installed at the rear of the main body 10 between the two positioning posts 12; a hollow area 14 is provided in the receiving cavity 11 of the main body 10, and a film applicator 20 which can slide repeatedly along the first direction and is used to press the film and stick the film to the mobile phone is installed in the hollow area 14. The insert 30 is engaged with the side wall of the accommodating cavity 11; when applying the film, the mobile phone is placed in the accommodating cavity 11 of the main body 10 with the screen facing upwards, and the position of the insert 30 is adjusted so that the insert 30 defines the position of the mobile phone to prevent the mobile phone from shaking when applying the film. The release layer of the film is torn off, and the positioning holes on one side of the protective layer on the film are inserted into the two positioning posts 12 to align the film with the mobile phone screen, and the film-applying member 20 is pushed to move along the first direction. The conical roller 21 rolls the film on the edge of the mobile phone, and the straight roller 22 rolls the film on the mobile phone screen, so that the film fits the mobile phone screen, and at the same time, bubbles are avoided when applying the film, and the film-applying efficiency is high and the film-applying quality is good.
[0027] In order to ensure that the film member 20 can move in a unidirectional manner along the first direction on the main body 10, please refer to Figure 4 and Figure 5 A one-way limiting structure 15 is provided on the main body 10, and the one-way limiting structure 15 includes guide protrusions 150 respectively formed on both sides of the main body 10 and extending outward along the width direction of the main body 10, and a matching sliding portion 151 provided on the lower side of the guide protrusion 150 and recessed inward along the width direction of the main body 10. The cross-section of the connection between the guide protrusion 150 and the matching sliding portion 151 is stepped. The one-way limiting structure 15 also includes a stopper 152 provided at the head and tail of the main body 10 and having a thickness greater than the guide protrusion 150, that is, the stopper 152 is respectively provided on the left and right sides of the guide protrusion 150 and the matching sliding portion 151. Through the stopper 152, the film member 20 will not separate from the main body 10 when sliding back and forth along the guide protrusion 150 and the matching sliding portion 151 on the main body 10.
[0028] In this example, see Figure 3 The film sticking member 20 is a U-shaped handle, which is located in the hollow part of the handle, and the inner wall of the handle is symmetrically provided with movable grooves for installing the tapered roller 21 and the straight roller 22. There are also protrusions 23 formed at both ends of the handle for sliding with the matching sliding part 151. The top surface of the protrusion 23 contacts the bottom surface of the guide protrusion 150, and when the film sticking member 20 is pushed, the protrusion 23 blocks the film sticking member 20 from the main body 10, and an anti-slip pattern 24 is provided on the upper surface of the handle to facilitate pushing the film sticking member 20.
[0029] In addition, it should be noted that a number of protrusions 16 are symmetrically formed on the side walls along the first direction in the accommodating cavity 11 of the main body 10, and the height of the protrusions 16 is lower than the accommodating cavity 11, so that a small mobile phone can be placed in the accommodating cavity 11 and limited front and rear by the protrusions 16, and a large mobile phone can be supported by the protrusions 16.
[0030] In this embodiment, in order to quickly and conveniently install the film member 20 on the main body 10, please refer to Figure 4 A process groove 17 is provided on the guide protrusion 150 near the stop portion 152, and the bottom surface of the process groove 17 gradually tilts upward along the sliding portion. When the film part 20 is assembled on the main body 10, the two ends of the film part 20 are aligned with the process groove 17, and a force is applied to the film part 20 and the main body 10, so that the film part 20 slides along the bottom surface of the process groove 17, and the two ends of the film part 20 slide into the recessed matching sliding portion 151, and the bottom surface of the process groove 17 is tilted, so that the protrusions 23 on both sides of the film part 20 can slide on the bottom surface, gradually expanding the film part 20, so that the protrusions 23 on the film part 20 quickly slide to the matching sliding portion 151.
[0031] In addition, when carrying, the film piece 20 will slide back and forth on the main body 10. In order to prevent the film piece 20 from moving on the main body 10, a fixed protrusion 153 is formed on the matching sliding portion 151 on the lower side of the process groove 17, and the protrusions 23 at both ends of the film piece 20 are provided with grooves 25 that match the fixed protrusions 153. After the fixed protrusions 153 are inserted into the grooves 25, the film piece 20 can be prevented from moving due to the pressing force of the film piece 20.
[0032] In this example, see Figure 5 An upper flange edge 140 and a lower flange edge 141 are formed on both side walls of the hollow area 14 of the accommodating cavity 11 along the first direction, a slide groove 142 for sliding of the insert 30 is formed between the upper flange edge 140 and the lower flange edge 141, and the lower flange edge 141 is provided with a break 143 for inserting the insert 30 into the slide groove 142, and the length of the break 143 is greater than the length of the insert 30. This arrangement can realize the installation and sliding of the insert 30.
[0033] Also, see Figure 6 The insert 30 includes a sliding plate 31 and a stopper 32 integrally formed with the sliding plate 31. The sliding plate 31 has protruding edges 33 inserted into the sliding groove 142 and contact edges 34 arranged in a step with the protruding edges 33 and in contact with the end surface of the upper flange edge 140 on opposite sides. Through this arrangement, the insert 30 will not be displaced during movement, and the pushing is relatively smooth and the operation speed is fast.
[0034] Furthermore, in order to prevent the insert 30 from moving when the film is applied, the side wall of the slide groove 142 is provided with a wavy first limiting portion 144, and the end face of the protruding edge 33 is provided with a wavy second limiting portion 35 that is consistent with the first limiting portion 144. The relative engagement of the first limiting portion 144 and the second limiting portion 35 can prevent the insert 30 from moving when the film is applied, thereby effectively ensuring the quality of the film application.
[0035] Preferably, in order to facilitate the rapid assembly of the insert 30 into the slide groove 142, the end faces of the protruding edges 33 located on both sides of the second limiting portion 35 are inclined surfaces 36, and the end faces at both ends of the protruding edges 33 are set as inclined surfaces 36. During assembly, one end of the inclined surface 36 is first inserted into the slide groove 142. In the absence of engagement between the second limiting portion 35 and the first limiting portion 144, the insert 30 can be quickly inserted into the slide groove 142.
[0036] In this embodiment, the middle part of the insert 30 is hollowed out, which can effectively reduce the weight of the product and save material usage; the top of the block 32 is gradually inclined toward the sliding plate 31, and a notch 320 is formed at the top of the block 32, and a hook 321 is formed in the notch 320. The block 32 with an inclined top is convenient for pushing the insert 30, and the hook 321 is convenient for hanging the product with a practical hanging line.
[0037] It should be noted that, in the present embodiment, the main body 10, the insert 30 and the film member 20 are made of plastic. In other embodiments, the main body 10, the insert 30 and the film member 20 may be made of metal materials, which will not be described in detail here.
[0038] In summary, the utility model sets a movable insert 30 in the accommodating cavity 11 of the main body, and limits the position of the mobile phone through the insert 30 so that it does not shake, so that one mobile phone film applicator can be compatible with films of different mobile phones, reducing production processes and costs, and setting the insert 30 to bite the side wall of the accommodating cavity 11, effectively avoiding loosening of the insert 30 when applying the film, preventing the film from being applied skewed, and ensuring that the film is well and effectively attached to the mobile phone.
[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
