Description

Technical field:

[0001] The utility model relates to the technical field of mobile phone film pasting, in particular to a lever-type film pasting device, which reduces the magnitude of external force applied when pasting the film through a lever-type structure, thereby improving the convenience of film pasting. Background technology:

[0002] Mobile phone protective films usually refer to a layer of film applied to the mobile phone screen to protect the mobile phone screen. They can be divided into: anti-peep film, mirror film, AR film, frosted film, high-definition film, anti-scratch protective film, 3D film, mobile phone body anti-scratch protective film, diamond film, protective film body, etc. Users can choose or replace different types of mobile phone protective films according to their own needs when purchasing a mobile phone or using it. In order to facilitate the film application, the film applicator came into being.

[0003] The current film applicators can be divided into scraper type, roller type and self-adhesive type according to the film application method. For the roller type film applicator, its working principle is: a pressure roller is provided on the film applicator. When in use, the protective film is adhered to the surface of the mobile phone screen through the relative movement between the pressure roller and the mobile phone positioning seat. In the process of rolling, the pressure roller gradually crushes and discharges the air between the protective film and the mobile phone screen, thereby achieving a perfect film application effect.

[0004] For the rolling film applicator, according to the different movement modes, it can be divided into the following two modes:

[0005] The first method is that the pressure roller is relatively stationary, and the positioning seat drives the mobile phone to move. For example, see the utility model patent with Chinese patent application number: 202223437428.1, which discloses a film sticking box and a film sticking assembly, and the technical solution adopted is: the inner shell (positioning seat) is used relative to the base, and the pressing part (pressure roller) installed on the base rolls the mobile phone protective film in the inner shell to complete the film sticking.

[0006] The second method is that the positioning seat is relatively stationary, and the user directly pushes the pressure roller to move. For example, the utility model patent with Chinese patent number: 202222793757.3 discloses a roller film laminating device with accurate laminating position. The technical solution adopted is: install a pressure roller on the sliding bracket, and by pushing the sliding bracket to move, the pressure roller rolls the protective film on the surface of the mobile phone to complete the film laminating.

[0007] The inventor has also developed a rolling film applicator and proposed a corresponding improved technical solution, see the utility model patent application with Chinese patent application number: 202420087234.3, which proposes a film applicator suitable for a pull-type protective film. The film applicator adopts the first method mentioned above, that is, the pressure roller is relatively stationary, and the positioning seat drives the mobile phone to move. However, during the actual test of the rolling film applicator, the inventor found the following problems:

[0008] Since the pressure rollers are relatively different, the positioning seat needs to drive the mobile phone to move along the base. During the movement of the positioning seat, a certain pressing force must be maintained between the surface of the mobile phone and the pressure roller. In this case, when pulling out the positioning seat, a large pulling force needs to be applied to smoothly pull the positioning seat to slide relative to the base. If the pressing force between the surface of the mobile phone and the pressure roller is insufficient, it is difficult to ensure perfect film application; while ensuring that the pressing force between the surface of the mobile phone and the pressure roller is sufficient, a large pulling force must be applied to pull the positioning seat. This is very unfriendly to female users with weaker strength.

[0009] In view of the above situation, the inventors thought of using the lever principle to add a lever structure to the existing roller-type film laminator to reduce the force applied. The positioning seat can be pushed by a smaller force to complete the film laminating operation. Therefore, the inventors proposed the following technical solution. Utility model content:

[0010] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a lever-type film applicator which can greatly reduce the force applied when applying the film and improve the convenience of film applicator.

[0011] In order to solve the above technical problems, the utility model adopts the following technical solutions: a lever-type film applicator, comprising: a force plate, a positioning seat and a base, the positioning seat can be relatively slidably installed on the base, and a positioning cavity for accommodating and positioning the mobile phone is arranged on the positioning seat, one end of the base is pivotally connected to the force plate, and a rolling member is arranged at a position of the base away from the pivoted force plate, a linkage is arranged between the force plate and the positioning seat, one end of the linkage is pivotally connected to the middle area of ​​the force plate, and the other end of the linkage acts on the positioning seat; when the force plate rotates relative to the base, the linkage driven by the force plate will push the positioning seat to slide along the base, and the positioning seat passes from under the rolling member, so that the rolling member moves relatively from the starting end to the end end of the mobile phone, and rolls the protective film covering the top of the mobile phone while moving relatively, to complete the attachment of the protective film.

[0012] Furthermore, in the above technical solution, the linkage member includes: a linkage plate, a first pivot and a drive seat, one end of the linkage plate is pivotally connected to the force plate through the first pivot; the drive seat is pivotally connected to the other end of the linkage plate.

[0013] Furthermore, in the above technical solution, the driving seat includes: a crossbeam pivotally connected to the linkage plate, positioning blocks arranged at both ends of the crossbeam and extending downward, and the positioning seat is provided with a positioning groove cooperating with the positioning block.

[0014] Furthermore, in the above technical solution, the positioning groove is provided on the positioning seat at one end adjacent to the pivotal position between the base and the force applying plate.

[0015] Furthermore, in the above technical solution, a receiving groove cooperating with the positioning block is further provided on the positioning seat at a position away from the positioning groove.

[0016] Furthermore, in the above technical solution, the base has a drawer cavity for accommodating the positioning seat, the drawer cavity is open on one side adjacent to the rolling element, and the positioning seat slides along the base and extends from the open side of the drawer cavity.

[0017] Furthermore, in the above technical solution, a guide rail is provided in the drawer cavity, and a slide groove cooperating with the guide rail is provided on the bottom surface of the positioning seat.

[0018] Furthermore, in the above technical solution, the rolling member is a pressure roller with both ends pivotally connected to the base, and the rolling member adopts a double-roller structure, which includes: a first pressure roller and a second pressure roller arranged parallel to each other.

[0019] Furthermore, in the above technical solution, the force-applying plate is a cover plate matched with the base, that is, the force-applying plate can be covered on the base, and a relatively closed box body is formed by the mutual covering of the force-applying plate and the base.

[0020] Furthermore, in the above technical solution, a reinforcing rib is provided in the middle of the force applying plate, and one end of the linking member is pivotally connected to the position of the reinforcing rib on the force applying plate.

[0021] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0022] 1. The force plate and the linkage in the utility model constitute a linkage mechanism, wherein the force plate is used as a lever structure, one end of the linkage is pivotally connected to the middle area of ​​the force plate, and the linkage is shorter than the first force arm formed between the pivotal position of the force plate and the base, and the user acts on the farthest end of the force plate, and the second force arm applied by the user is the length of the entire force plate, and the length of the second force arm is greater than the length of the first force arm, and a relatively small external force can generate a relatively large thrust on the linkage, so that the linkage driven by the force plate will push the positioning seat to slide along the base, and the positioning seat passes from under the rolling member, so that the rolling member moves relatively from the starting end to the end end of the mobile phone, and rolls the protective film covering the top of the mobile phone while moving relatively, completing the attachment of the protective film. In addition, there is no need to set a pull-out handle on the positioning plate, which effectively reduces the length of the product.

[0023] 2. The force-applying plate of the utility model can be directly designed as a cover plate that matches the base. The user can complete the film application operation while closing the cover plate, which is convenient to operate. At the same time, the cover plate and the base cooperate with each other to form a relatively closed box body, which can prevent external dust and impurities from entering and ensure that the mobile phone protective film will not be contaminated.

[0024] 3. In order to further improve the film laminating effect, the utility model can adopt a double pressure roller structure to overcome the problem of bubble residue caused by deformation of a single pressure roller in existing products, and finally achieve a good laminating effect.

[0033] The utility model is further described below in conjunction with specific embodiments and drawings.

[0034] See Figures 1 to 7 As shown, the utility model comprises: a force applying plate 1, a positioning seat 2, a base 3, a rolling member 4, and a linkage member 5.

[0035] The force plate 1 is used as a force-applying component of the utility model, and it plays the role of a lever. One end of the force plate 1 is pivotally connected to one end of the base 3, that is, the force plate 1 can rotate along the pivotal position between it and the base 3. As for the specific form, the force plate 1 can directly adopt a plate, a long rod, or the like with a certain rigidity. In the utility model, in order to make the structure of the entire product beautiful and unified, the force plate 1 is designed to be a cover plate. That is, the force plate 1 is a cover plate that cooperates with the base 3, that is, the force plate 1 can be covered on the base 3, and a relatively closed box body is formed by the mutual covering of the force plate 1 and the base 3.

[0036] A reinforcing rib 10 is arranged in the middle of the inner surface of the cover plate 1, which can improve the rigidity of the force plate 1 and avoid large deformation or even breakage during the film application process. One end of the linkage 5 is pivotally connected to the position of the reinforcing rib 10 on the force plate 1.

[0037] The base 3 has a drawer cavity 30 for accommodating the positioning seat 2. One end of the base 3 is pivotally connected to the force plate 1, and a rolling member 4 is arranged at a position of the base 3 away from the pivotally connected force plate 1. The drawer cavity 30 is open on one side adjacent to the rolling member 4, and the positioning seat 2 can extend from the opening side of the drawer cavity 30 when sliding along the base 3.

[0038] The drawer cavity 30 is provided with a guide rail 31, which cooperates with the slide groove 23 provided on the bottom surface of the positioning seat 2 to form a slide rail matching structure, thereby improving the accuracy of the positioning seat 2 sliding along the base 3. The upper edge of the drawer cavity 30 is formed as a limit plate 32, which is used to limit the positioning seat 2 in the drawer cavity 30 to prevent the positioning seat 2 from escaping from the drawer cavity 30.

[0039] The rolling element 4 is a roller with both ends pivotally connected to the base 3. In order to improve the film laminating quality, the rolling element 4 of the utility model can adopt a double roller structure, which includes: a first roller 41 and a second roller 42 arranged parallel to each other. The first roller 41 and the second roller 42 can be designed with equal lengths, such as Figure 2 , Figure 3As shown. Of course, another better way can be adopted: the length of the first pressing roller 41 is greater than that of the second pressing roller 42, and the second pressing roller 42 is located in front of the middle area of ​​the first pressing roller 41. The length of the first pressing roller 41 and the second pressing roller 42 refers to the distance between the left end face of the pressing roller and the right end face thereof, wherein the length of the first pressing roller 41 must be greater than the width of the mobile phone screen to ensure the full rolling of the mobile phone screen. In order to achieve a better rolling film effect, the length of the second pressing roller 42 is less than two-thirds of the width of the mobile phone screen (or protective film) and greater than one-tenth of the width of the mobile phone screen (or protective film). If the length of the second pressing roller 42 is too long, it will cause deformation and bubbles; if the length is too short, it may not be possible to squeeze out the bubbles in the middle area of ​​the protective film. When in use, during the relative movement of the rolling member 4 from the starting end to the end section of the mobile phone, the roller surface of the second pressing roller 42 located in the front first contacts the protective film and rolls the middle area of ​​the protective film, and the roller surface of the first pressing roller 41 located in the rear contacts the protective film and rolls the protective film. Finally, a perfect film effect is achieved.

[0040] The positioning seat 2 can be relatively slidably installed on the base 3, and a positioning cavity 20 for accommodating and positioning the mobile phone 6 is provided on the positioning seat 2.

[0041] A positioning groove 21 is provided on one end of the positioning seat 2 adjacent to the pivotal position of the base 3 and the force-applying plate 1. A receiving groove 22 is also provided on the positioning seat 2 at a position away from the positioning groove 21.

[0042] As mentioned above, the bottom surface of the positioning seat 2 is provided with a slide groove 23 that cooperates with the guide rail 31. When assembling, the positioning seat 2 is inserted into the base 3 from the opening end of the drawer cavity 30.

[0043] The linkage 5 is located between the force plate 1 and the positioning seat 2, one end of the linkage 5 is pivoted to the middle area of ​​the force plate 1, and the other end of the linkage 5 acts on the positioning seat 2. Specifically, the linkage 5 includes: a linkage plate 51, a first pivot 52 and a drive seat 53, one end of the linkage plate 51 is pivoted to the position of the reinforcing rib 10 of the force plate 1 through the first pivot 52. The drive seat 53 is pivoted to the other end of the linkage plate 51, that is, the second pivots 54 are integrally formed on both sides of the lower end of the linkage plate 51, and the drive seat 53 is provided with a pivot position 530 for installing the linkage plate 51, and pivot holes cooperating with the second pivot 54 are provided on both sides of the pivot position 530.

[0044] The driving seat 53 comprises: a crossbeam 531 pivotally connected to the linkage plate 51, and positioning blocks 532 arranged at both ends of the crossbeam 531 and extending downward. The positioning blocks 532 cooperate with the positioning grooves 21 arranged on the positioning seat 2. The pivoting position 530 is formed on the crossbeam 531.

[0045] See Figure 8 As shown, when the utility model is used, the force application plate 1 needs to be opened first, and the positioning seat 2 is stored in the pull-out cavity 30 of the base 3. The mobile phone 6 is placed in the positioning cavity 20 of the positioning seat 2. The shape of the positioning cavity 20 corresponds to the shape of the mobile phone 6 that needs to be fitted, and the mobile phone 6 is positioned by the positioning cavity 20 to ensure that the mobile phone 6 and the positioning seat 2 remain relatively fixed during the film application process. The protective film 7 that needs to be fitted is placed above the mobile phone 6, and the protective film 7 can be positioned by the positioning portion provided on the positioning seat 2. At this time, the positioning block 532 in the linkage 5 falls into the positioning groove 21 on the positioning seat 2.

[0046] Then, the user applies a covering external force to the end of the force-applying plate 1 that is pivotally connected away from the base 3. The force-applying plate 1 rotates relative to the base 3 under the external force, and the linkage 5 driven by the force-applying plate 5 pushes the positioning seat 2 to slide along the base 3. The positioning seat 2 passes under the rolling member 4, causing the rolling member 4 to move relatively from the starting end to the end end of the mobile phone 6, and while moving relatively, the protective film 7 covering the top of the mobile phone 6 is rolled to complete the attachment of the protective film.

[0047] According to the above-mentioned usage, the force plate 1 and the linkage 5 in the utility model constitute a linkage mechanism, wherein the force plate 1 is a lever structure, one end of the linkage 5 is pivoted to the middle area of ​​the force plate 1, and the linkage 5 is shorter than the first lever arm formed between the pivotal position of the force plate 1 and the base 3, and the user acts on the farthest side of the force plate. The second lever arm applied by the user is the length of the entire force plate 1, and the second lever arm length is greater than the first lever arm length. A relatively small external force can generate a relatively large thrust on the linkage 5, so that the linkage 5 driven by the force plate 1 will push the positioning seat 2 to slide along the base 3, making film application more labor-saving, and even female users can easily complete the film application.

[0048] In addition, the preferred embodiment of the present invention is that the positioning block 532 in the linkage 5 and the positioning groove 21 on the positioning seat 2 are detachably nested and docked, that is, the positioning block 532 in the linkage 5 is directly dropped into the positioning groove 21 on the positioning seat 2. The advantage of this method is that if the positioning block 532 is pivotally connected to the positioning groove 21, when the force plate 1 is in the closed state in a non-use state (such as the sales stage), the positioning seat 2 is pushed out of the base 3, and the length of the entire product is greatly increased, which is inconvenient for the storage and packaging of the product. After the detachable nesting is adopted, combined with Figure 7As shown, in the non-use state, when the force-applying plate 1 is in the covered state, the positioning block 532 can be separated from the positioning groove 21, and the entire linkage 5 is pushed by the force-applying plate 1 to be located above the positioning seat 2 and in a roughly horizontal state. In this way, the positioning seat 2 will not be pushed out of the base 3, the length of the entire product will not increase, and the storage and packaging of the product will be convenient.

[0049] In addition, with respect to the above embodiment, a receiving groove 22 is further provided on the positioning seat 2 at a position away from the positioning groove 21. Figure 7 As shown, in the non-use state, when the force plate 1 is in the covered state, the linkage plate 51 is approximately in a horizontal state, and the positioning block 532 on the drive seat 53 falls into the receiving groove 22, which can effectively reduce the height of the entire linkage 5 and reduce the thickness of the entire product.

[0050] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
