Referring to fig. 1 to 7, a mobile phone protection case provided by the present invention will be described. A protective case for a mobile phone, comprising:

the locking assembly 2, the locking assembly 2 includes a first rotating shaft 21 and a rotating disc 22 fixed on the first rotating shaft 21, the rotating disc 22 has a locking part 23;

a housing 1 having a first through hole 11 into and out of which the locking portion 23 slides;

a locking structure (not shown) for locking the housing 1 with the locking portion 23 when the turntable 22 rotates in the first direction 5 relative to the housing 1, and unlocking the housing 1 from the locking portion 23 when the turntable 22 rotates in a direction opposite to the first direction 5 relative to the housing 1; the locking structure is arranged between the housing 1 and the latch assembly 2.

By sliding the locking portion 23 into the first through hole 11 and locking the housing 1 with the locking portion 23 when the turntable 22 rotates relative to the housing 1 along the first direction 5, the housing 1 and the latch assembly 2 are fixed to each other, and a user's hand can be fixed to the latch assembly 2 and maintain a stable connection relationship with the housing 1. Meanwhile, when the turntable 22 rotates relative to the shell 1 along the direction opposite to the first direction 5, the shell 1 and the locking part 23 are unlocked, and then the locking part 23 slides out of the first through hole 11, so that the shell 1 and the lock catch assembly 2 are separated, and the disassembly is very convenient.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the locking structure includes a first latch plate 3 protruding on an inner wall of the first through hole 11, the locking portion 23 includes a fixing column 231 fixed on the turntable 22 and a second latch plate 232 protruding on the fixing column 231, and the turntable 22, the fixing column 231 and the second latch plate 232 enclose a receiving cavity (not shown) into which the first latch plate 3 is snapped. So, first buckle plate 3 card is gone into in the holding chamber and is got up hasp subassembly 2 and casing 1 buckle fixed connection, and the same reason, first buckle plate 3 takes out from the holding chamber then can make the buckle fixed connection disconnection between hasp subassembly 2 and the casing 1.

Alternatively, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the length of the fixing post 231 in the extending direction of the first rotation shaft 21 is not greater than the thickness of the casing 1. In this way, when the fixing post 231 slides into the first through hole 11, it does not pass through the housing 1 to affect the mobile phone or other devices fixedly connected to the housing 1 at the other side.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, a protruding portion 2321 is protruding from the second fastening plate 232 in the accommodating cavity, and a recess portion 31 matched with the protruding portion 2321 is concavely formed on the first fastening plate 3. In this way, the protrusion 2321 and the recess 31 cooperate with each other to effectively prevent the first buckle plate 3 and the second buckle plate 232 from sliding relatively, so as to enhance the connection relationship between the latch assembly 2 and the housing 1.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, an arc guiding surface (not shown) for guiding the concave portion 31 and the convex portion 2321 to cooperate with each other is connected between the convex portion 2321 and the second fastening plate 232. In this way, the protruding portion 2321 and the concave portion 31 can be guided to mutually buckle through the arc-shaped guiding surface in the process of mutually matching and buckling, so that the protruding portion 2321 and the concave portion 31 can smoothly realize buckling and releasing buckling.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the number of locking portions 23 is at least two, and at least two locking portions 23 are spaced apart and circumferentially arranged. In this way, the at least two locking portions 23 can lock the latch assembly 2 and the housing 1 more firmly. At least two locking parts 23 are arranged at intervals and are circumferentially distributed, so that the locking assembly 2 is stressed more uniformly when being fixed with the shell 1. Alternatively, the spacing between the center of rotation (not shown) of the turntable 22 and all of the latches 23 is the same, so that the latches 23 can be replaced with each other.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the number of locking portions 23 is two, and the two locking portions 23 are respectively disposed at two sides of a junction (not shown) between the first rotating shaft 21 and the turntable 22. So, two locking parts 23 simple structure be convenient for production, two locking parts 23 set up in the both sides of intersection portion respectively for the atress is more balanced when the hasp subassembly 2 forms the buckle through between locking part 23 and the casing 1 to be connected, has strengthened the connection stability between hasp subassembly 2 and the casing 1.

Further, referring to fig. 1 to 7, as an embodiment of the mobile phone protection case provided by the present invention, the latch assembly 2 further includes a ring buckle 4 and a second rotating shaft (not shown), and the ring buckle 4 is pivotally connected to the first rotating shaft 21 through the second rotating shaft. Thus, the finger ring buckle 4 can rotate around the second rotating shaft, and people can change the position of the finger ring buckle 4 according to actual demands.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the case 1 further has a second through hole 12 for the first rotating shaft 21 to slide in and slide out. In this way, the first shaft 21 slides into the second through hole 12, so as to effectively help the locking portion 23 slide into the first through hole 11, and during the process of sliding the locking portion 23 into the first through hole 11, the first shaft 21 and the second through hole 12 can be aligned and placed into the second through hole 12, and the turntable 22 can be rotated again to adjust and align the locking portion 23 and the first through hole 11. In addition, after the housing 1 is locked with the locking portion 23, the first rotating shaft 21 can effectively prevent the whole locking assembly 2 from moving in the radial direction of the rotating disc 22, so that the stability of the connection relationship between the locking assembly 2 and the housing 1 is ensured.

Further, referring to fig. 1 to 7, as a specific embodiment of the mobile phone protection case provided by the present invention, the number of the first through holes 11 is plural, the number of the second through holes 12 is plural, the plural second through holes 12 are arranged side by side, and the plural first through holes 11 are respectively arranged side by side on two sides of the plural second through holes 12. In this way, the locking portion 23 can slide into different first through holes 11 according to the requirement, so that a plurality of fixable positions exist between the locking assembly 2 and the housing 1 to meet different requirements of different users.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
