[0025] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figures 1 to 4As shown, this embodiment discloses a film sticking tool 10, including: a positioning frame 20; an adsorption component 30, which is arranged on the positioning frame 20; wherein, a pressing hole 21 and a mounting hole 22 are provided on the positioning frame 20, the adsorption component 30 is provided on the mounting hole 22, and the pressing holes 21 are provided on both sides of the mounting hole 22, the adsorption component 30 includes an airway portion 33, a suction cup portion 31 and an air valve portion 32, the suction cup portion 31 is used to adsorb the membrane 41, and the air valve portion 32 is connected with the suction cup portion 31 through the airway portion 33.

[0027] By placing the diaphragm 41 on the positioning frame 20, the positioning frame 20 is aligned and installed on the electronic device 40 to be pasted with the film. During the process of the suction cup part 31 adsorbing the diaphragm 41, the channel 34 part and the air valve part 32 cooperate to discharge the air from the suction cup part 31 to adsorb the diaphragm 41, and the pressing hole 21 is used to press the diaphragm 41 tightly against the screen of the electronic device 40. After the film is pasted, the air valve part 32 is controlled to enter the air so that the suction cup part 31 and the diaphragm 41 are separated to complete the film pasting, making the operation of the entire film pasting process convenient and more intuitive. The alignment of the positioning frame 20 and the use of the adsorption part 30 make the film pasting operation more efficient. The film pasting tool 10 can be reused, which reduces material waste and is more environmentally friendly. It is suitable for various electronic devices 40 that need to be pasted with films.

[0028] Among them, the air valve part 32 includes a duckbill valve 321, the airway part 33 includes a channel 34, the suction cup part 31 includes a suction cup 311, the duckbill valve 321 is connected to the suction cup 311 through the channel 34, and the inner side of the positioning frame 20 is provided with a limiting groove 24 for placing the diaphragm 41, and the pressing hole 21 and the mounting hole 22 are arranged at the bottom of the limiting groove 24. A fastener 35 is provided on the outside of the airway portion 33, and a limiting protrusion 23 is provided on the edge of the mounting hole 22. The fastener 35 includes an elastic portion 351 and an annular groove 352. The annular groove 352 is clamped with the limiting protrusion 23. The annular groove 352 is connected to the outside of the airway portion 33 through the elastic portion 351. The elastic portion 351 is made of silicone material. When the adsorbent 30 is pressed, the elastic portion 351 is stretched, so that the adsorbent 30 can cooperate to discharge the air from the suction cup portion 31 to adsorb the diaphragm 41. When the pressure on the adsorbent 30 is cancelled, the adsorbent 30 as a whole is under the action of the elastic portion 351. Reset so that the suction cup part 31 drives the diaphragm 41 to be adsorbed in the limiting groove 24 on the positioning frame 20, and then after removing the protective film 42 of the diaphragm 41, the positioning frame 20 is placed on the screen of the electronic device 40 at the corresponding position above the screen. There is a pressing hole 21 on the positioning frame 20, and the diaphragm 41 is pressed with a finger, and then the air valve part 32 is opened to connect the channel 34 to the outside air, and the diaphragm 41 is separated from the suction cup part 31, and the positioning frame 20 is removed to complete the film application; the outer wall of the optional adsorbent 30 and the mounting hole 22 are directly interference fit, which is convenient for assembly without the need for other fasteners 35, more environmentally friendly and convenient to install.

[0029] Among them, pressing the adsorbent 30 can cooperate to expel the air in the suction cup 311 to adsorb the diaphragm 41. When the pressure on the adsorbent 30 is released, the adsorbent 30 as a whole is reset under the action of the elastic part 351 made of silicone material, so that the suction cup 311 drives the diaphragm 41 to be adsorbed in the limiting groove 24 on the positioning frame 20. After removing the protective film 42 of the diaphragm 41, the positioning frame 20 is placed above the screen to correspond to and position it on the screen of the electronic device 40. There is a pressing hole 21 on the positioning frame 20. Press the diaphragm 41 with your finger, and then open the duckbill valve 321 to connect the channel 34 with the outside air to achieve air pressure balance. The diaphragm 41 is separated from the suction cup 311, and the positioning frame 20 is removed to complete the film pasting.

[0030] Among them, the airway part 33 includes an airway side wall 341 and a flexible side wall 342. The flexible side wall 342 and the airway side wall 341 enclose a channel 34. The flexible side wall 342 connects the air valve part 32 and the airway side wall 341. When the adsorbent 30 is pressed, the flexible side wall 342 is folded under force, so that the volume of the channel 34 is reduced and the corresponding volume of air is discharged, thereby better forming an air pressure difference, ensuring that the suction cup 311 can more stably adsorb the membrane 41, making the entire film-sticking process easy to operate and the film-sticking process more intuitive.

[0031] Among them, the airway side wall 341 and the flexible side wall 342 are made of silicone material by integral molding. The integral molding makes the production of the adsorbent 30 more convenient and simple, and at the same time can very well ensure the overall air tightness of the airway part 33; the thickness of the flexible side wall 342 is less than the thickness of the airway side wall 341, which can ensure that the flexible side wall 342 can bend and fold quickly when subjected to a pressing force, so that the volume of the channel 34 is reduced to discharge the corresponding volume of air, thereby better forming an air pressure difference and ensuring that the suction cup 311 can more stably adsorb the membrane 41; of course, the elasticity of the flexible side wall 342 and the airway side wall 341 can be made different by changing the material, changing the structure, etc.

[0032] Among them, the positioning frame 20 includes a film pasting part 25, and the limiting groove 24 is arranged in the film pasting part 25. The film pasting part 25 is made of transparent material. The film pasting part 25 is a transparent material, and the state of the film 41 can be visually checked, so that the operation of the entire film pasting process is convenient and the film pasting process is more intuitive; the optional positioning frame 20 is integrally formed with transparent material as a whole, which makes the production of the positioning frame 20 more convenient.

[0033] Among them, the positioning frame 20 includes a positioning part 26 fixedly connected to the film-applying part 25, and the positioning part 26 is provided with a side guard plate 261 and an avoidance position 262 for avoiding components on the film-applied device. The setting of the avoidance position 262 enables the positioning frame 20 to be better suitable for electronic devices 40 with electronic display screens such as mobile phones, tablets, computers, smart watches, remote control devices, handheld game consoles, cameras, etc., and can avoid related buttons, operating levers, paddles and other components. The setting of the side guard plate 261 can limit the position to a certain extent to avoid shaking during the film-applying process, thereby making the film-applying operation more efficient.

[0034] Among them, the airway part 33, the suction cup part 31 and the air valve part 32 are made of one-piece molding. The one-piece molding makes the production of the adsorption part 30 more convenient and simple, and at the same time can very well ensure the airtightness of the connection between the airway part 33, the air valve part 32 and the suction cup part 31.

[0035] Specifically, Figure 1 As shown, when performing the film sticking operation, the film 41 is placed in the limiting groove 24 of the positioning frame 20, and the front side of the film 41 is pressed by hand, and the back side is pressed by fingers to press the adsorbent 30 so that the suction cup 311 is squeezed and deformed upward to discharge part of the air. The suction cup 311 is completely in contact with the film 41 and then adsorbed in the positioning frame 20. At this time, the protective film 42 is removed, and the next step is as shown in FIG. Figure 4 As shown, the positioning frame 20 is then positioned above the screen of the electronic device 40, the film sticking tool 10 is installed on the electronic product in position, the diaphragm 41 is pressed with a finger at the pressing hole 21 to make it contact with the screen, and the positioning frame 20 is removed after squeezing the duckbill valve 321 to complete the exhaust, thereby completing the film sticking.

[0036] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
