DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the present application provides an anti-crack tempered film, which solves the problem that the corners of the existing tempered film may be cracked if the mobile phone is often placed together with sharp objects or hard objects, or if the corners are accidentally scratched during use.

[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 embodiment discloses an anti-crack tempered film according to the attached Figure 1-7 As shown, it includes a tempered film body 1, a protective unit 2 is arranged on the outer side of the tempered film body 1, the protective unit 2 includes a first frame 201 and a second frame 202, and the tempered film body 1 is movably clamped between the first frame 201 and the second frame 202;

[0030] A positioning bolt 3 is threadedly connected between the first frame 201 and the second frame 202;

[0031] The anti-cracking tempered film has a protective unit 2 added to the outside of the tempered film body 1 to provide protection, so that the corners are not easy to crack, and the service life of the tempered film body 1 is improved. The protective unit 2 is composed of a first frame 201 and a second frame 202, which is easy to assemble and easy to reuse. The first frame 201 and the second frame 202 are connected by a positioning bolt 3.

[0032] The second frame 202 is internally movably connected with an embedded glue stick 4, which squeezes the positioning bolt 3. The clamping of the embedded glue stick 4 can, on the one hand, limit the squeezing of the positioning bolt 3 to prevent the positioning bolt 3 from being squeezed loose or coming loose, and on the other hand, ensure that the appearance of the second frame 202 is flat and beautiful.

[0033] An embedding groove 101 is provided on the side of the tempered film body 1, a first clamping strip 2011 that is clamped with the embedding groove 101 is provided on the first frame 201, and a second clamping strip 2021 that is clamped with the embedding groove 101 is provided on the second frame 202. The device is designed with the first clamping strip 2011 and the second clamping strip 2021, so that when the first frame 201 and the second frame 202 are clamped and limited with the tempered film body 1, the first clamping strip 2011 and the second clamping strip 2021 are respectively clamped with the embedding groove 101, thereby ensuring the good stability of the first frame 201 and the second frame 202.

[0034] A first positioning sleeve 2012 is embedded in the interior of the first frame 201, and a second positioning sleeve 2022 is embedded in the interior of the second frame 202. The positioning bolt 3 passes through the second positioning sleeve 2022 and is threadedly connected in the first positioning sleeve 2012. The device is designed with the first positioning sleeve 2012 and the second positioning sleeve 2022 so that the positioning bolt 3 can fix the first frame 201 and the second frame 202 stably and reliably.

[0035] A rubber ring 301 is sleeved on the positioning bolt 3. The design of the rubber ring 301 ensures that when the positioning bolt 3 locks the first frame 201 and the second frame 202, the locking position has less wear and greater friction.

[0036] The embedded glue stick 4 is provided with a plurality of groups of snap rings 401, and a limiting hole 402 is opened on the embedded glue stick 4. Through the design of the plurality of groups of snap rings 401, the embedded glue stick 4 is conveniently clamped in the circular hole of the second frame 202, and the clamping is stable and not easy to loosen, thereby achieving a good limiting effect on the positioning bolt 3. At the same time, with the design of the limiting hole 402, the embedded glue stick 4 is convenient to rotate, thereby facilitating the removal of the embedded glue stick 4.

[0037] The embedded glue stick 4 is provided with an arc surface 403 corresponding to the corner of the second frame 202. Through the design of the arc surface 403, the outer side of the embedded glue stick 4 is flush with the second frame 202, making the second frame 202 beautiful.

[0038] The tempered film body 1 is provided with a rounded corner 102 , and the rounded corner 102 design makes the force at the contact position between the tempered film body 1 and the protective unit 2 stable and not easy to break.
