Description
Technical Field
The utility model relates to a pad pasting device from type membrane structure of leveling indicates especially that what make screen protection paste does not stick up from the type membrane, makes it keep flat.
Background
As a screen protector for electronic devices such as smart phones, tablet computers or notebook computers, the adhesive surface of the screen protector is usually provided with a release film, and an adhesive layer is arranged between the protective protector and the release film; after the release film is torn, the protection sticker exposing the sticking layer can be stuck on the screen. Because the screen and the hole position of the mobile phone need to be accurately corresponding when the protection paste is pasted, the protection paste can be matched with an auxiliary film pasting device to assist a user to paste the screen protection paste by himself; along with the design evolution of the auxiliary film sticking device, the length of a release film of the protective paste arranged on the auxiliary film sticking device is longer than that of the protective paste, and the release film comprises a sticking part, a turning part and an extending part; the joint part is adhered with the protection paste, the turning part is arranged between the joint part and the extension part, and the turning part is reversely folded to form a folding line end, so that the extension part can be oppositely and detachably overlapped with the joint part, the length of the extension part is longer than that of the protection paste, and one end of the extension part, which is far away from the folding line end, is exposed out of the outer edge of the auxiliary film pasting device. When the auxiliary film pasting device is used, the protection paste of the auxiliary film pasting device is correspondingly arranged on the screen, the extending part is arranged between the screen and the pasting part, the extending part protruding out of the auxiliary film pasting device is pulled, the pasting part is reversely folded and torn, static electricity is generated to adsorb and take away dust on the screen, and meanwhile, the protection paste is pasted on the screen. However, as shown in fig. 1, since the bending part 14 of the release film 12 is folded reversely, the folding force of the bending end 141 makes both sides of the film bulge, so that the surface between the attaching part 13 and the bending part 14 is arc-shaped and uneven, and the edge of the attaching part 13 and the edge of the protection sticker 10 are separated and not adhered reliably, thus, the surface of the adhesive layer 11 of the protection sticker 10 is exposed to contact with air over a long time, and is likely to be adhered with fine dust, and the protection sticker is sold to consumers, which is likely to cause poor quality problems such as air bubbles, failure to adhere or unfirm adhesion, and the appearance is also affected after the attachment; therefore, how to improve the turning portion 14 of the release film 12 to be flat without causing the fold line end 141 to bulge and generating a gap H between the protection tape 10 is needed in the prior art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the above problem, and provide a sticking film device from type membrane structure that levels, main technique and purpose are: at least one hollow hole is arranged at the fold line end of the release film, so that the sectional area of the fold line end is reduced, and the elastic force strength of the fold line end is weakened, the bending and the deformation of the turning part of the release film are prevented, and the effect of easy leveling is achieved.
According to the above object of the present invention, there is provided a release film leveling structure of a film pasting device, wherein the film pasting device has a positioning space, a protection sticker is disposed in the positioning space, the protection sticker is adhered with a release film, and the release film comprises a pasting portion, a turning portion and an extending portion; the joint part is adhered with the protective sticker, the turning part is arranged between the joint part and the extension part, and the turning part is reversely bent to form a folding line end, so that the extension part can be bent to be overlapped with the joint part, and one end of the extension part, which is far away from the folding line end, is exposed out of the outer edge of the film pasting device; the method is characterized in that: the fold line end is provided with a plurality of hollow holes.
In an embodiment of the present invention, the hollow holes are arranged at equal intervals.
The hollow hole weakens the strength of the elastic restoring force of the fold line end, and the effect of easy leveling is achieved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 2 and fig. 3, a release film leveling structure of a film pasting device, wherein a film pasting device 20 is rectangular, a positioning space 21 is formed on a bottom surface of the film pasting device, a protection paste 22 is disposed in the positioning space 21, a release film 23 is detachably pasted on the bottom surface of the protection paste 22, and the release film 23 includes a pasting portion 24, a turning portion 25 and an extending portion 26; the attaching portion 24 is adhered to the protection sticker 22, the bending portion 25 is located between the attaching portion 24 and the extending portion 26, and the bending portion 25 is bent reversely to form a bending end 251, so that the extending portion 25 can be bent relatively and detachably overlapped with the attaching portion 24, the extending portion 26 is longer than the protection sticker 22, and one end of the extending portion 26, which is far away from the bending end 251, is exposed out of the outer edge of the film attaching device 20; a plurality of hollow holes 27 arranged at equal intervals are arranged along the fold line end 251, and the strength of the elastic restoring force of the fold line end 251 is weakened through the hollow holes 27, so that the effect of easy leveling is achieved.
The composition, action and efficacy of the above examples are explained in detail as follows: as shown in fig. 2 and 3, the protection paste 22 of the present invention can be made of scratch-resistant and wear-resistant toughened glass or plastic sheet, the release film 23 can be a film made of plastic, and the attaching portion 24, the turning portion 25 and the extending portion 26 are integrally formed or formed by bonding a plurality of pieces; the film sticking device 20 can be made of a hard plastic material, but not limited thereto; furthermore, the fold line of the fold line end 251 is because the polymer chain is oriented by force, and is basically irreversible, but the release film 23 is made of soft and tough plastic material, and usually has no obvious yield point, so that the fold line end 251 still has some elastic force for recovery, and the turning part 25 generates a bulging and uneven shape; the sectional area of the fold line end 251 is reduced by the hollow hole 27, so that the elastic force for restoring the fold line end 251 is relatively reduced, and the surface between the attaching portion 24 and the turning portion 25 is relatively flat, thereby ensuring that the edges of the attaching portion 24 and the protection sticker 22 are not warped, and ensuring that no gap is generated during bonding.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
