Description

Technical Field

[0001] The utility model relates to the technical field of film sticking, and in particular to a magnetic film sticking artifact. Background Art

[0002] With the advent of the Internet age, electronic devices have become an indispensable tool in our lives. However, the screens of electronic devices are sometimes too fragile and are often accidentally scratched or even broken, which affects the display effect and aesthetics of the electronic devices. Replacing the screen requires a lot of money and time. Therefore, people usually put a protective film on the screen of the electronic device to protect the tablet or electronic device screen.

[0003] When MagSafe technology is applied to mobile phones, the biggest usage scenario is to bring them close together and align them through magnetic attraction. One of the benefits of alignment is that the wireless charging experience is greatly improved. The mobile phone and wireless charger can only be charged when they are aligned. In order to align, if there is no magnetic attraction, you may have to repeat the action of placing (finding the position, aligning) several times until you are sure to start charging. This magnetic attraction is achieved through a magnetic sheet installed on the back of the electronic device.

[0004] In real life, when applying film to the surface of electronic devices, a film-applying artifact is usually used to assist in the application. A film-applying artifact is only suitable for electronic devices of one size. However, some consumers now have multiple electronic devices and need to purchase different film-applying artifacts to apply film to electronic devices of different models, which is quite expensive.

[0005] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The utility model provides Figure 1-4 The magnetic film sticking artifact shown is used to stick a protective film to the screen of an electronic device with a magnetic sheet on the back. The protective film includes a PET film and a tempered film. The PET film is provided with an anti-fool groove. The protective film is a conventional technical means well known to those skilled in the art, so it will not be elaborated.

[0030] The top plate 101 comprises a top plate 101, the bottom of which is detachably connected to a bottom plate 102, the two of which can be snap-connected, a first clamping rod 103 is fixedly installed on the top surface of the top plate 101, a receiving cavity 104 is provided at the bottom of the top plate 101, a limiting plate 201 is slidably connected in the receiving cavity 104, a stretching plate 202 is fixedly installed on one end of the limiting plate 201 extending out of the receiving cavity 104, a second clamping rod 203 is fixedly installed on the top of the stretching plate 202, and anti-fool protrusions 4 that match the shape and position of the anti-fool groove are fixedly installed on the first clamping rod 103 and the second clamping rod 203, a magnetic suction groove 105 is also provided on the top surface of the top plate 101, a fixedly installed magnetic suction sheet 5 is accommodated in the magnetic suction groove 105, and the magnetic suction sheet 5 has the same shape as the magnetic attraction sheet on the back of the electronic device, positioning sheets 301 that fit the inner wall of the top plate 101 are also fixedly installed on both sides of the limiting plate 201, and a spring 303 is fixedly installed between the positioning sheet 301 and the inner wall of the top plate 101;

[0031] When the user is ready to apply a film to an electronic device with a magnetic sheet on the back, the user makes the top surface of the top plate 101 face upwards, and then makes the back of the electronic device face downwards, so that the back of the electronic device is temporarily located on the first clamping rod 103 and the second clamping rod 203, and then respectively pinches the top plate 101 and the stretching plate 202 with both hands to move them away from each other. At this time, the limit plate 201 slides in the accommodating cavity 104, driving the positioning plate 301 to compress the spring 303. As the spring 303 is compressed, the distance between the first clamping rod 103 and the second clamping rod 203 will increase. At this time, the electronic device is pushed between the first clamping rod 103 and the second clamping rod 203 with the fingers. Since the magnetic sheet 5 has the same shape as the magnetic sheet on the back of the electronic device, the electronic device will be between the magnetic sheet 5 and the magnetic sheet. Under the action of the magnetic force between the magnetic sheets, the electronic device will be adsorbed onto the surface of the top plate 101 and moved to a predetermined position. At this time, the left and right sides of the electronic device are at predetermined positions. After that, the user lets go, and the elastic force generated when the compressed spring 303 is reset will drive the first clamping rod 103 and the second clamping rod 203 to clamp the two sides of the electronic device. From then on, the four sides of the electronic device, up, down, left, and right, are clamped between the first clamping rod 103 and the second clamping rod 203 according to the preset position; finally, the user installs the existing protective film on the first clamping rod 103 and the second clamping rod 203 through the cooperation between the anti-fool groove and the anti-fool protrusion 4, and finally sticks the protective film to the screen of the electronic device according to the conventional film sticking method.
