Description

Technical Field

[0001] This utility model relates to a mobile phone case, specifically a four-corner drop-proof mobile phone case. Background Technology

[0002] A phone case is a tool to protect and enhance the appearance of a mobile phone. Currently, most phone cases are made of plastic or are molded from a single piece. They only serve to cover the phone and offer limited shock and drop protection. Summary of the Invention

[0003] The purpose of this utility model is to provide a four-corner anti-drop phone case to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A four-corner drop-proof phone case includes a PC top cover, a TUP shell, and a PC bottom cover; the PC bottom cover and the PC top cover are clamped together to connect the TUP shell, and the front of the TUP shell has a receiving groove for installing a phone.

[0006] As a further embodiment of this utility model: the TUP shell is made of TUP rubber and has a hollow structure.

[0007] As a further embodiment of this utility model: the four corners of the TUP shell are integrally formed with airbags.

[0008] As a further embodiment of this utility model, the airbag is integrally formed with through holes.

[0009] As a further embodiment of this utility model: the PC upper cover has a buckle integrally formed at the edge of the PC lower cover facing the PC lower cover, and the edge of the PC lower cover has a groove integrally formed at the position corresponding to the buckle, and the PC upper cover and the PC lower cover are connected by the corresponding buckle and groove.

[0010] As a further embodiment of this utility model, the PC cover is square-shaped.

[0011] As a further embodiment of this utility model, the PC lower cover is also square-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The TUP shell uses TUP rubber material combined with PC material for the bottom and top covers, giving the entire phone case excellent shock resistance. At the same time, the four corners of the TUP shell have airbags, which significantly improves the phone's drop protection. Attached Figure Description

[0014] Figure 1 This is a diagram illustrating the explosion of a four-corner anti-drop phone case.

[0015] Figure 2 This is a schematic diagram of a four-corner drop-proof phone case.

[0016] Figure 3 This is a side view of a four-corner drop-proof phone case. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figures 1-3 In this embodiment of the utility model, a four-corner anti-drop phone case includes a PC top cover 1, a colorful sheet 2, a TUP shell 3, and a PC bottom cover 4;

[0019] The TUP shell 3 is used to fit over the back of the mobile phone. The front and back of the TUP shell 3 are respectively provided with a PC upper cover 1 and a PC lower cover 4, and the PC upper cover 1 and PC lower cover 4 are connected by corresponding buckles 11 and slots.

[0020] Specifically, the TUP shell 3 is made of TUP rubber and has a hollow structure. Airbags 31 are integrally formed at the four corners of the TUP shell 3. Through holes are integrally formed on the airbags 31 for connecting ropes or chains.

[0021] The TUP housing 3 has button holes formed on its side, and a button is slidably installed in the button holes. The TUP housing 3 and the PC lower cover 4 also have through slots corresponding to the positions of the mobile phone camera. At the same time, the side of the TUP housing 3 also has charging through holes and speaker through holes, etc., which are known to those skilled in the art and will not be described in detail here.
