Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of film pasting equipment, and particularly relates to a film pasting box. BACKGROUND

[0002] In the use process of modern electronic devices, a screen protection film is a common protective accessory, which is used to prevent screen scratches, fingerprint pollution and reduce direct damage to the screen.

[0003] At present, users usually use film pasting equipment to assist in screen pasting operation; since most of the current film pasting equipment needs to let the roller roll through the entire mobile phone screen in the use process, it is inevitable that the internal parts of the film pasting equipment will involve sliding cooperation between different elements, and the sliding cooperation on the existing film pasting equipment is usually only the cooperation between a single roller and a sliding rail, which is prone to sliding difficulty and jamming during the film pasting process. This not only increases the operation difficulty, but also may cause uneven film pasting, bubble generation and even damage to the screen protection film itself, thereby affecting the final protection effect and screen visual effect.

[0014] Preferably, a first mounting part is arranged in the receiving cavity, the elastic guide structure is located above the first mounting part, the top surface of the first mounting part is provided with a first positioning part, and the elastic guide structure is provided with an avoidance hole corresponding to the first positioning part.

[0015] Compared with the prior art, the film pasting box has the following advantages:

[0016] 1. In this embodiment of the invention, the housing assembly serves as the basic frame of the film application box. A push-pull assembly slidably mounted on the housing assembly is used for film application. By providing a slide rail on the housing and a roller assembly on the push-pull assembly that cooperates with the slide rail, the push-pull assembly can move smoothly along a predetermined trajectory. By providing a first roller and a second roller with non-parallel axes on the push-pull assembly and having both rollers cooperate with the slide rail, multiple mating surfaces exist when the push-pull assembly slides relative to the housing assembly. It is understood that the axes of rotation of the first roller and the second roller are not parallel, i.e., they are at an angle. Therefore, the sliding surfaces on the slide rail that cooperate with the two rollers are also at an angle. By introducing more angled sliding mating surfaces, the push-pull assembly and the housing assembly contact each other in multiple directions via rollers and the slide rail. This effectively avoids the sliding difficulties and jamming caused by hard interference between the push-pull assembly and the housing assembly after offset, improving the smoothness of film application for the user and optimizing the user experience.

[0017] 2. In this embodiment of the invention, the roller assembly is installed by fixing arms at both ends of the push-pull assembly. The roller assembly is symmetrically arranged on the two fixing arms, which can further improve the smoothness and stability of the sliding assembly. By directly setting the first mounting shaft on the working surface, it is convenient to disassemble and assemble the first roller.

[0018] 3. In this embodiment of the invention, the second mounting position is used to mount the second roller. Since the rotation axes of the first roller and the second roller are not parallel, when the two rollers are simultaneously mounted on the same working surface, there is a difference in the actual external space occupied by the two. In this solution, a recessed mounting cavity is provided on the fixed arm. By setting the second mounting shaft and the second roller in the mounting cavity, the actual external space occupied by the second roller can be greatly reduced. At this time, only a part of the second roller is exposed on the working surface, and the actual external space occupied by the second roller is determined by the depth of the mounting cavity and the second roller itself.

[0019] 4. In this embodiment of the invention, the push-pull assembly further includes a connecting rod, and the fixed arm is detachably connected to the connecting rod. It is understood that since the roller assembly in this solution includes two types of rollers, and these two types of rollers are installed on the push-pull assembly, it is difficult to directly assemble the push-pull assembly into a module and then install the push-pull assembly with the housing assembly. In this solution, by setting the connecting rod and fixed arm in the push-pull assembly to be detachably connected, during the assembly process, the fixed arm can be placed in the corresponding position in the housing assembly first, and then the installation and fixation between the connecting rod and the fixed arm can be completed. At the same time, the detachable design also enhances the cleanability and maintainability of the film box, making it easier for users to disassemble, maintain, and clean the film box.

[0020] 5. In this embodiment of the invention, since the push-pull assembly includes a connecting rod and fixed arms located at both ends of the connecting rod, the assembly and disassembly involve the cooperation between multiple parts. Especially during installation, if only one person operates it, both alignment and fixation are required, which is not very convenient. This solution pre-sets a first pre-fixing structure and a second pre-fixing structure that cooperate with each other on the connecting rod and the fixed arm, which facilitates the pre-fixation of the connecting rod and the fixed arm during installation. This eliminates the need to spend extra effort to align and maintain the positioning of the connecting rod and the fixed arm during the final fixation, reducing the assembly difficulty of the film box, improving production efficiency, and making it easier to maintain.

[0021] 6. In this embodiment of the invention, because the film applicator involves both pushing and pulling actions during use, a first gripping slope and a second gripping slope are respectively provided on the two opposite sides of the connecting rod, taking ergonomics into account and providing a better grip and operability. The inclined design of the gripping surface makes it more comfortable for the user to hold.

[0022] 7. In this embodiment of the invention, a first abutting structure and a second abutting structure are provided on the corresponding inner wall surface and mating surface of the fixed arm and the inner housing. The push-pull assembly is limited by the abutting cooperation of the two, which can effectively prevent the push-pull assembly from moving excessively on the housing assembly, thereby preventing damage to the roller, fixed arm and housing assembly.

[0023] 8. In this embodiment of the invention, by setting the receiving cavity as a cavity that penetrates the fixed arm, the second roller can be exposed from two opposite sides of the working surface and inner wall surface of the fixed arm. This allows the user or production worker to hold the second roller from opposite sides, making it easier to fine-tune and align the position of the second roller during installation, and further reducing the assembly difficulty.

[0024] 9. In this embodiment of the invention, by setting an elastic guide structure with a height higher than the top surface of the inner shell, the push-pull component will squeeze the elastic guide structure when sliding. Since there is a deformation space between the movable end of the elastic guide structure and the bottom surface of the receiving cavity, the elastic guide structure can deform downwards, thereby driving the protective film to press down during the film application process. This solves the problem that existing film application boxes cannot properly complete the application of the protective film to the curved surface when applying films to curved screen electronic devices.

[0025] 10. In this embodiment of the invention, a first positioning part for fixing the external protective film is provided on the first mounting part, so that the starting position of the protective film corresponds to the position of the elastic guiding structure, which facilitates the movement of the protective film when the elastic guiding structure deforms.

[0050] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0051] The terms "vertical", "horizontal", "left", "right", "up", "down", "upper left", "upper right", "lower left", "lower right" and similar expressions used herein are only for illustrative purposes.

[0052] Referring to Figure 1 , the first embodiment of the present application provides a sticker box, comprising a shell assembly 100 and a push-pull assembly 200 slidably arranged on the shell assembly 100.

[0053] It can be understood that the shell assembly 100 in the embodiment of the present application is the basic frame of the sticker box, and the push-pull assembly 200 slidably arranged on the shell assembly 100 is used for sticker operation. It should be noted that the device protection film is attached to the corresponding device to be pasted by the push-pull assembly 200, which is a conventional technical means in the art, and will not be described here. The device to be pasted can be a mobile phone, a tablet computer and a watch, etc. In this embodiment, a mobile phone is taken as an example for description.

[0054] Referring to Figure 3 , Figure 4 and Figure 6 , as an optional implementation, the two ends of the push-pull assembly 200 are respectively provided with a roller set 5, the roller set 5 comprises at least one first roller 51 and at least one second roller 52, the rotation shaft of the first roller 51 and the rotation shaft of the second roller 52 are not parallelly arranged; the shell assembly 100 comprises an outer shell 1, the sidewall of the outer shell 1 is provided with a slide rail 16, and the first roller 51 and the second roller 52 are matched with the slide rail 16.

[0055] It can be understood that by setting the sliding rail 16 on the outer shell 1 and setting the roller set 5 on the push-pull assembly 200 to cooperate with the sliding rail 16, the push-pull assembly 200 can be smoothly moved along the predetermined track; by setting the first roller 51 and the second roller 52 with non-parallel rotation shafts on the push-pull assembly 200 and allowing the first roller 51 and the second roller 52 to cooperate with the sliding rail 16 at the same time, the push-pull assembly 200 has multiple cooperation surfaces 24 when sliding relative to the shell assembly 100. It can be understood that the rotation shafts of the first roller 51 and the second roller 52 are non-parallel, that is, they are arranged at an angle. Therefore, the sliding surfaces on the sliding rail 16 that cooperate with the two rollers are also arranged at an angle. By introducing more angled sliding cooperation surfaces 24, the push-pull assembly 200 and the shell assembly 100 are in contact with the sliding rail 16 in multiple directions, effectively avoiding the hard interference between the push-pull assembly 200 and the shell assembly 100 caused by the deviation of the push-pull assembly 200, which leads to poor sliding and jamming, thereby improving the smoothness of the user when using the film sticking box to stick the film and optimizing the use experience of the film sticking box.

[0056] In particular, the rotation shafts of the first roller 51 and the second roller 52 refer to the axes of their rotation centers, not the specific shaft structures.

[0057] Specifically, in the present embodiment, the rotation shafts of the first roller 51 and the second roller 52 are perpendicular. Correspondingly, the cooperation surfaces 24 on the sliding rail 16 for cooperating with the first roller 51 and the second roller 52 are also perpendicular.

[0058] It can be understood that in the present embodiment, the corresponding cooperation surfaces 24 on the sliding rail 16 are set to be perpendicular for easier processing; however, setting the corresponding cooperation surfaces 24 on the sliding rail 16 to other acute or obtuse angle relationships can also be achieved through different processing methods. Considering the different materials and rotation of the shell assembly 100, injection molding or machining with a corresponding shaped tool bit can be used; and the cooperation of the two rollers with various angles can provide longitudinal and transverse limiting forces, thereby avoiding poor sliding and jamming caused by the deviation of the push-pull assembly 200. Therefore, the specific angle relationship between the rotation shafts of the first roller 51 and the second roller 52 is not strictly limited in the present solution.

[0059] Optionally, the number of first rollers 51 and second rollers 52 can be designed according to actual requirements; in the present embodiment, considering the cost and stability, the roller set 5 includes two first rollers 51 and two second rollers 52, that is, four first rollers 51 and four second rollers 52 are arranged at both ends of the push-pull assembly 200.

[0060] Please refer to Figure 4 and Figure 6As an optional embodiment, the two ends of the push-pull assembly 200 are respectively provided with fixed arms 42, and the roller set 5 is arranged on the fixed arms 42; the surface away from each other of the fixed arms 42 is a working surface 425, and the working surface 425 is provided with a first mounting position 422, which comprises a first mounting shaft 4221 connected with the fixed arm 42, and the first roller 51 is sleeved on the first mounting shaft 4221.

[0061] It can be understood that, by arranging the fixed arms 42 at the two ends of the push-pull assembly 200 to install the roller set 5, and symmetrically arranging the roller set 5 on the two fixed arms 42, the sliding fluency and stability of the push-pull assembly 200 can be further improved; by directly arranging the first mounting shaft 4221 on the working surface 425, the first roller 51 can be conveniently disassembled and assembled.

[0062] Alternatively, the first mounting shaft 4221 can be an integral structure directly formed on the fixed arm 42; or, the first mounting shaft 4221 and the fixed arm 42 are detachable split structures. Specifically, in the embodiment, the first mounting shaft 4221 and the fixed arm 42 are an integral structure.

[0063] Further, after the first roller 51 is installed on the first mounting shaft 4221, the first roller 51 rolls in cooperation with the top surface and / or the bottom surface of the slide rail 16, which is determined according to the position of the first mounting shaft 4221 and the size of the first roller 51.

[0064] Further, the end surface of the first mounting shaft 4221 is arranged opposite to the side wall of the slide rail 16, and there is a gap between the end surface of the first mounting shaft 4221 and the side surface of the slide rail 16. It can be understood that, because the end surface of the first mounting shaft 4221 also moves relative to the side surface of the slide rail 16 when the push-pull assembly 200 slides relative to the shell assembly 100, a certain gap is maintained to avoid interference between the two, thereby ensuring the sliding fluency.

[0065] Further, the gap between the end surface of the first mounting shaft 4221 and the side surface of the slide rail 16 is less than the thickness of the first roller 51. It can be understood that this design can prevent the first roller 51 from detaching from the first mounting shaft 4221, thereby ensuring the working stability of the push-pull assembly 200.

[0066] Further, the push-pull assembly 200 further comprises a roller shaft 6 rotatably arranged between the two fixed arms 42.

[0067] Further, please refer to Figure 5The second installation position 423 is arranged on the working surface 425, and the second installation position 423 comprises an installation cavity 4231 arranged on the fixed arm 42, and a second installation shaft 4232 is arranged in the installation cavity 4231, and the second roller 52 is sleeved on the second installation shaft 4232, and at least a partial area of the second roller 52 is exposed to the working surface 425.

[0068] It can be understood that the second installation position 423 is used for installing the second roller 52 in the embodiment of the application, and since the rotation shafts of the first roller 51 and the second roller 52 are not arranged in parallel, when the two rollers are arranged on the same working surface 425 at the same time, the actual external space occupied by the two rollers is different, and in the present scheme, the installation cavity 4231 is arranged in the fixed arm 42, and the second installation shaft 4232 and the second roller 52 are arranged in the installation cavity 4231, so that the actual external space occupied by the second roller 52 can be greatly reduced, and at this time, only a partial area of the second roller 52 is exposed to the working surface 425, and the actual external space occupied by the second roller 52 is determined by the depth of the installation cavity 4231 and the second roller 52 itself.

[0069] Further, referring to Figure 5 The installation cavity 4231 has a top surface and a bottom surface, the top surface of the installation cavity 4231 is provided with a locking hole 4233, the bottom surface of the installation cavity 4231 is provided with a through hole 4234 corresponding to the locking hole 4233, the second installation shaft 4232 passes through the through hole 4234 and is connected with the locking hole 4233 of the installation cavity 4231, and the second roller 52 is sleeved on the second installation shaft 4232 and located in the installation cavity 4231.

[0070] Specifically, in the embodiment, when the second roller 52 rolls, the circumferential outer surface of the second roller 52 is matched with the side wall of the slide rail 16.

[0071] It should be noted that, due to the different relative positions of the first roller 51 and the second roller 52, the first roller 51 can be matched with only the top surface of the slide rail 16 or only the bottom surface of the slide rail 16.

[0072] Specifically, in the embodiment, the corresponding first installation position 422 is located above the second installation position 423 on the single fixed arm 42, that is, the first roller 51 is located above the second roller 52, and therefore, when the first roller 51 rolls, the first roller 51 is matched with only the top surface of the slide rail 16.

[0073] Further, referring to Figure 4 The push-pull assembly 200 further comprises a connecting rod 41, and the fixed arm 42 is detachably connected with the connecting rod 41.

[0074] It can be understood that, since the roller set 5 in the scheme includes two kinds of rollers, and the two kinds of rollers are installed on the push-pull assembly 200, it is relatively difficult to directly assemble the push-pull assembly 200 into a module (see Figure 3 ) and then install the push-pull assembly 200 and the shell assembly 100. In the scheme, the connecting rod 41 and the fixed arm 42 in the push-pull assembly 200 are detachably connected. During assembly, the fixed arm 42 is first placed in the corresponding position in the shell assembly 100, and then the installation and fixation between the connecting rod 41 and the fixed arm 42 are completed. At the same time, the detachable setting also enhances the cleanability and maintainability of the film pasting box, facilitating the user to disassemble, maintain and clean the film pasting box.

[0075] As a feasible implementation manner, if it is not desired to set the push-pull assembly 200 to be detachable, other installation manners can be used, such as making the shell assembly 100 detachable.

[0076] Further, referring to Figure 4 , the push-pull assembly 200 further includes a locking piece 43. The end of the connecting rod 41 is provided with a first pre-fixing structure 411, and the fixed arm 42 is provided with a second pre-fixing structure 421 matched with the first pre-fixing structure 411. The locking piece 43 is detachably connected through the fixed arm 42 and the first pre-fixing structure 411 at the end of the connecting rod 41 or a region other than the first pre-fixing structure 411.

[0077] It can be understood that, in the embodiment of the application, since the push-pull assembly 200 includes the connecting rod 41 and the fixed arms 42 at both ends of the connecting rod 41, the cooperation between multiple components is involved during disassembly and assembly, especially during installation. If only one person operates alone, alignment and fixation are both required, which is not very convenient. The scheme pre-provides the first pre-fixing structure 411 and the second pre-fixing structure 421 on the connecting rod 41 and the fixed arm 42 for cooperation, so that the connecting rod 41 and the fixed arm 42 are pre-fixed during installation. Therefore, additional efforts are not required to maintain the positioning state between the connecting rod 41 and the fixed arm 42 during the final fixation, which reduces the assembly difficulty of the film pasting box, improves production efficiency, and is easy to maintain.

[0078] Specifically, in the embodiment, the first pre-fixing structure 411 is a protruding structure, and the second pre-fixing structure 421 is an inner recess structure. In addition, the first pre-fixing structure 411 is provided with a threaded hole, and the corresponding threaded hole of the second pre-fixing structure 421 is provided with a light hole. The locking piece 43 is matched with the threaded hole after passing through the light hole, so as to realize the detachable connection of the connecting rod 41 and the fixed arm 42.

[0079] Further, the working surface 425 of the fixing arm 42 is provided with a shielding member 44 corresponding to the mounting position of the locking member 43, which plays a role of shielding and beautifying.

[0080] Further, the two opposite sides of the connecting rod 41 are respectively provided with a first holding inclined surface 412 and a second holding inclined surface 413, and the first holding inclined surface 412 and the second holding inclined surface 413 are inclined towards each other at one end close to the shell assembly 100.

[0081] It can be understood that, in the embodiment of the application, because the film pasting box involves both pushing and pulling actions during use, the first holding inclined surface 412 and the second holding inclined surface 413 are arranged on the two opposite sides of the connecting rod 41, which considers ergonomics and provides better holding feeling and operability. The inclined design of the holding surface makes the user more comfortable when holding.

[0082] Please refer to Figure 1 , as an optional embodiment, the shell assembly 100 further comprises an inner shell 2, and the outer shell 1 is provided with a receiving cavity 11, and the inner shell 2 is arranged in the receiving cavity 11.

[0083] Please refer to Figure 1 and Figure 2 , as an optional embodiment, the shell assembly 100 comprises an outer shell 1 and an inner shell 2, the outer shell 1 is provided with a receiving cavity 11, and the inner shell 2 is detachably arranged in the receiving cavity 11.

[0084] It can be understood that the detachability of the inner shell 2 facilitates the user to replace the corresponding inner shell 2 according to the actual use demand for different models of film pasting equipment, has strong universality, and also facilitates the user to disassemble and assemble the film pasting box for maintenance and cleaning of the inside of the film pasting box, thereby improving the convenience of maintenance and cleaning.

[0085] Further, the film pasting box in the embodiment can be used to implement film pasting for different customers in a store or a stall, and therefore, in order to enable the film pasting box to be used for a long time, the shell assembly 100 is preferably made of a durable material, such as a material with high hardness or wear resistance.

[0115] Further, the number of the second positioning part 1914 is two, which are arranged at the two ends of the top of the mounting frame 1911.

[0116] Specifically, the second positioning part 1914 is a fixed column.

[0117] Further, please refer to Figure 12~Figure 14The connecting rod 1922 comprises a first inclined section 19221, a smooth section 19222, a second inclined section 19223 and a third inclined section 19224 connected in sequence.

The ejecting part 1923 is connected to one end of the third inclined section 19224 away from the smooth section 19222. The first inclined section 19221 and the second inclined section 19223 are both inclined towards the direction of the bottom surface of the accommodating cavity 11. It can be understood that this design is to keep the pressing part 1921 at a higher position in the initial state, which is convenient for operation.

[0119] It can be understood that by arranging the third magnetic assembly 19211 and the fourth magnetic assembly 152, the pressing part 1921 and the bottom surface of the accommodating cavity 11 have a magnetic attraction function. When the user wants to take out the electronic device after completing the film pasting, the user only needs to press the pressing part 1921 in sequence, and the pressing part 1921 and the shell 1 can be kept in the pressed state through the magnetic attraction between the third magnetic assembly 19211 and the fourth magnetic assembly 152, without the need for the user to continuously press, so that the user can complete the operation with one hand, which is convenient.

[0120] Further, the ejecting part 1923 is provided with a fifth magnetic assembly 19231, and the bottom surface of the accommodating cavity 11 is provided with a sixth magnetic assembly 153 corresponding to the fifth magnetic assembly 19231.

[0121] It can be understood that by arranging the fifth magnetic assembly 19231 and the sixth magnetic assembly 153, the ejecting part 1923 and the bottom surface of the accommodating cavity 11 have a magnetic attraction function. In the non-ejecting state, the ejecting part 1923 and the bottom surface of the accommodating cavity 11 are magnetically connected, which is stable. After the user has taken out the electronic device, the user only needs to press the ejecting part 1923 slightly to release the magnetic attraction between the third magnetic assembly 19211 and the fourth magnetic assembly 152, and the ejecting part 1923 can be automatically reset under the magnetic attraction between the fifth magnetic assembly 19231 and the sixth magnetic assembly 153, which is convenient.

[0122] Further, the fixing frame 191 is detachably connected to the shell 1. It can be understood that this design provides the possibility of quick replacement and maintenance of the fixing frame 191.

[0124] It can be understood that, because the inner housing 2 is arranged in the accommodating cavity 11, if the circumferential outer surface of the inner housing 2 is completely fitted with the accommodating cavity 11 after installation, it is very difficult to install the inner housing 2, because it is very difficult to align, and by arranging the guide surface 23 on the inner housing 2, the installation of the inner housing 2 can be guided by the action area of the guide surface 23, without the need to actively perform too fine alignment, which is convenient for the user to quickly replace or disassemble the inner housing 2.

[0125] Further, please refer to Figure 1~Figure 14 The use process / principle of the film pasting box in the embodiment is briefly described as follows:

[0126] According to the rotation of the electronic device to be pasted with the film, the corresponding type of inner housing 2 is placed into the accommodating cavity 11 of the outer housing 1 through the guide surface 23, and is clamped between the first mounting portion 12 and the second mounting portion 13, so that the inner housing 2 is fixed under the action of the first magnetic attraction assembly 151 and the second magnetic attraction assembly 26, if there is other type of inner housing 2 in the outer housing 1 in advance, the inner housing 2 is pushed out through the through hole 14 at the bottom of the outer housing 1, and then the installation of the corresponding type of inner housing 2 is performed;

[0127] Then, the electronic device to be covered is placed into the placement cavity 20 of the inner housing 2. The protective film corresponding to the electronic device is positioned and fixed by the first positioning part 122 and the second positioning part 1914. The release film on the side of the protective film closest to the mobile phone is peeled off. During the peeling process, the release film contacts the surface of the electronic device to remove dust. The push-pull assembly 200 is operated to make the roller 6 roll the protective film and apply it to the screen of the electronic device. Before the roller 6 is above the conductive electronic device, it passes through the elastic guide structure 172. The elastic guide structure 172 is pressed downward, thereby driving one end of the protective film to move downward, completing the application to the curved screen. Protective film is applied to the curved part; after the application is completed, the push-pull assembly 200 is reset, the remaining fixing film of the protective film is removed, and the pressing part 1921 of the ejector 192 is pressed, thereby driving the ejector part 1923 to rise, so that the electronic device is ejected from the placement cavity 20 of the inner housing 2. At this time, due to the presence of the third magnetic suction assembly 19211 and the fourth magnetic suction assembly 152, even if the pressing part 1921 is stopped, the electronic device will remain in the ejected state, and the electronic device can be easily removed. After the entire film application process is completed and the electronic device is removed, the ejector part 1923 can be gently pushed to allow it to quickly reset under the action of the fifth magnetic suction assembly 19231 and the sixth magnetic suction assembly 153.

[0128] Compared with the prior art, the film box of the present invention has the following advantages:

[0129] 1. In this embodiment of the invention, the housing assembly serves as the basic frame of the film application box. A push-pull assembly slidably mounted on the housing assembly is used for film application. By providing a slide rail on the housing and a roller assembly on the push-pull assembly that cooperates with the slide rail, the push-pull assembly can move smoothly along a predetermined trajectory. By providing a first roller and a second roller with non-parallel axes on the push-pull assembly and having both rollers cooperate with the slide rail, multiple mating surfaces exist when the push-pull assembly slides relative to the housing assembly. It is understood that the axes of rotation of the first roller and the second roller are not parallel, i.e., they are at an angle. Therefore, the sliding surfaces on the slide rail that cooperate with the two rollers are also at an angle. By introducing more angled sliding mating surfaces, the push-pull assembly and the housing assembly contact each other in multiple directions via rollers and the slide rail. This effectively avoids the sliding difficulties and jamming caused by hard interference between the push-pull assembly and the housing assembly after offset, improving the smoothness of film application for the user and optimizing the user experience.

[0130] 2. In this embodiment of the invention, the roller assembly is installed by fixing arms at both ends of the push-pull assembly. The roller assembly is symmetrically arranged on the two fixing arms, which can further improve the smoothness and stability of the sliding assembly. By directly setting the first mounting shaft on the working surface, it is convenient to disassemble and assemble the first roller.

[0131] 3、The second mounting position in the embodiment of the application is used for mounting the second roller, since the rotation shafts of the first roller and the second roller are not arranged in parallel, and when the two rollers are arranged on the same working surface at the same time, the actual external space occupied by the two rollers is different, in the present scheme, the recessed mounting cavity is arranged on the fixed arm, the second mounting shaft and the second roller are arranged in the mounting cavity, which can greatly reduce the actual external space occupied by the second roller, at this time, only part of the second roller is exposed on the working surface, and the actual external space occupied by the second roller is determined by the depth of the mounting cavity and the second roller itself.

[0132] 4、The push-pull assembly further comprises a connecting rod, and the fixed arm is detachably connected with the connecting rod, it can be understood that since the roller set in the present scheme comprises two kinds of rollers, and the two kinds of rollers are mounted on the push-pull assembly, it is difficult to directly assemble the push-pull assembly into a module and then install the push-pull assembly and the shell assembly, in the present scheme, the connecting rod and the fixed arm in the push-pull assembly are detachably connected, during assembly, the fixed arm can be placed on the corresponding position in the shell assembly first, and then the installation and fixation between the connecting rod and the fixed arm are completed, meanwhile, the detachable design also enhances the cleanability and maintainability of the film pasting box, and facilitates the user to disassemble, maintain and clean the film pasting box.

[0133] 5、In the embodiment of the application, since the push-pull assembly comprises the connecting rod and the fixed arms located at both ends of the connecting rod, during disassembly and assembly, the cooperation between multiple components is involved, especially during installation, if only one person operates alone, alignment and fixation are both needed, and the operation is not very convenient, in the present scheme, the first pre-fixing structure and the second pre-fixing structure that cooperate with each other are prearranged on the connecting rod and the fixed arms, so that the connecting rod and the fixed arms are pre-fixed during installation, and when the final fixation is performed, additional efforts are not needed to maintain the positioning state between the connecting rod and the fixed arms, which reduces the assembly difficulty of the film pasting box, is beneficial to improve the production efficiency and is easy to maintain.

[0134] 6、In the embodiment of the application, since the film pasting box involves both pushing and pulling actions during use, the first holding inclined surface and the second holding inclined surface are arranged on the two opposite sides of the connecting rod, which considers ergonomics and provides better holding feeling and operability. The inclined design of the holding surface makes the user more comfortable when holding.

[0135] 7、The first and second abutting structures are arranged on the inner wall surface and the matching surface corresponding to the fixed arm and the inner shell, and the push-pull assembly is limited through the abutting and matching of the two, which can effectively avoid excessive movement of the push-pull assembly on the shell assembly, thereby avoiding crushing of the roller, the fixed arm and the shell assembly.

[0136] 8、In the embodiment of the present application, the accommodating cavity is arranged as a cavity penetrating through the fixed arm, so that the second roller can be exposed from the two opposite sides of the working surface and the inner wall surface of the fixed arm, so that the user or the production worker can hold the second roller from the opposite sides, which is convenient for fine adjustment and alignment of the position of the second roller during installation, and further reduces the assembly difficulty.

[0137] 9、In the embodiment of the present application, the elastic guide structure with a height higher than the top surface of the inner shell is arranged, so that the push-pull assembly can extrude the elastic guide structure when sliding, and since a deformation space is arranged between the movable end of the elastic guide structure and the bottom surface of the accommodating cavity, the elastic guide structure can be deformed downward at this time, thereby driving the pressing of the protective film during the film pasting process, which solves the problem that the existing film pasting box cannot well complete the pasting of the protective film and the curved surface when pasting the film on the curved screen electronic device.

[0138] 10、In the embodiment of the present application, the first positioning part for fixing the external protective film is arranged on the first mounting part, so that the starting position of the protective film corresponds to the position of the elastic guide structure, which is convenient for movement of the protective film when the elastic guide structure is deformed.

[0139] The film pasting box disclosed in the embodiments of the present application is described in detail, and the principles and implementation modes of the present application are described by applying specific examples; the above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed, and the above description should not be understood as a limitation of the present application; any modification, equivalent replacement and improvement within the principles of the present application should be included in the protection scope of the present application.
