Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Combination Figures 1 to 7 A scratch-resistant component for a mobile phone casing includes a protective mechanism 3 disposed on the back of the mobile phone. The protective mechanism 3 includes a support box 31, which is fixedly connected to the back of the mobile phone. A spring 32 is fixedly connected to the top of the inner wall of the support box 31. A rectangular block 33 is fixedly connected to the bottom of the spring 32. A connecting shaft 36 is fixedly connected to the bottom of the rectangular block 33. An internal spline 37 is fixedly connected to the bottom of the connecting shaft 36. A fixing shaft 34 is fixedly connected to one side of the rectangular block 33. A push block 35 is fixedly connected to the end of the fixing shaft 34 away from the rectangular block 33. A support block 38 is fixedly connected to the back of the mobile phone. A long shaft 39 is rotatably connected inside the support block 38. An external spline 303 is fixedly connected to the top of the long shaft 39. A connecting block 301 is fixedly connected to the outer wall of the long shaft 39. A protective cover 302 is fixedly connected to the left side of the connecting block 301.

[0032] Furthermore, the long shaft 39 passes through the support block 38, and the outer ring of the outer spline 303 engages with the inner wall of the inner spline 37, so that the inner spline 37 can lock the outer spline 303.

[0033] Furthermore, a circular hole is provided at the bottom of the support box 31, through which the connecting shaft 36 passes and moves, so that the rectangular block 33 can drive the connecting shaft 36 to move.

[0034] Furthermore, the rectangular block 33 is slidably connected to the inner wall of the support box 31, and the push block 35 has a protrusion fixedly connected to its right side, which facilitates the movement of the push block 35 by pushing it through the protrusion.

[0035] Furthermore, a slot is provided on the right side of the support box 31, through which the fixed shaft 34 passes, allowing the fixed shaft 34 to drive the rectangular block 33 to move and compress the spring 32.

[0036] Furthermore, the inner layer 11 is made of thermoplastic polyurethane, the middle layer 12 is made of silicone resin, and the outer layer 13 is made of silicon nitride coating to ensure the scratch resistance of the phone casing body 1.

[0037] In actual operation, when this device is in use, the smartphone body 2 can protect the phone casing 1, and the protective cover 302 can protect the lens of the smartphone body 2. When the lens of the smartphone body 2 needs to be used, first push the push block 35 upward, so that the push block 35 can drive the rectangular block 33 to move through the fixed shaft 34. The rectangular block 33 can drive the inner spline 37 upward through the connecting shaft 36, so that the inner spline 37 is no longer engaged with the outer spline 303, and the rectangular block 33 can compress the spring 32. At this time, the long shaft 39 is in a rotatable state. Then, the protective cover 302 can be pushed to rotate 180 degrees along the axis of the long shaft 39, so that the lens of the phone casing 1 can be exposed, which is convenient for the user to take pictures. Similarly, when the outer spline 303 and the inner spline 37 are engaged, the stability of the protective cover 302 can be ensured during protection and use, thereby reducing the possibility of the smartphone body 2 and lens being scratched by external influences, reducing damage to the lens and potential safety hazards.

[0038] This application also discloses a smartphone, including a phone case anti-scratch component according to any of the above embodiments, and also includes a smartphone body 2 and a phone case body 1 sleeved on the outside of the smartphone body 2. The smartphone body 2 of this application can be protected by the above-mentioned phone case anti-scratch component.

[0039] Furthermore, the mobile phone casing body 1 includes an inner layer 11, a middle layer 12 is fixedly connected to the bottom of the inner layer 11, and an outer layer 13 is fixedly connected to the bottom of the middle layer 12, thereby improving the strength and lifespan of the mobile phone casing body 1.

[0040] The inner layer 11 enables the phone casing body 1 to have anti-yellowing and hydrolysis resistance properties, the middle layer 12 enables the phone casing body 1 to have good mechanical strength, and the outer layer 13 enables it to have good hardness and friction performance.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
