Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone cases, and particularly relates to an inverted waterproof mobile phone case. Background Art

[0002] In order to protect the mobile phone, a protective case needs to be set on the outer side of the mobile phone, commonly known as a mobile phone case. In order to achieve the waterproof function of the mobile phone in special environments, the research on the waterproof function of the mobile phone case has begun.

[0003] The waterproof mobile phone cases in the prior art generally include a panel covering the operation interface of the mobile phone, a frame surrounding the mobile phone, and a back plate covering the back of the mobile phone, which are buckled together to form a mobile phone protection shell. The waterproofing at the contact points between several parts is the most crucial.

[0004] CN204836273U provides a fully enclosed waterproof mobile phone protection case, which is composed of a frame, a lower cover, a glass film, a camera patch, and a charging interface patch. The frame and the lower cover are only clamped through a first buckle groove and a second buckle groove, without a closed waterproof effect.

[0005] CN220528109U discloses a waterproof mobile phone case. Although inner and outer frames are provided, the mobile phone back plate and the frame are clamped through bumps and pits, without a waterproof effect, and can only be buckled, unable to achieve closed waterproofing. A sealing ring is additionally arranged between the mobile phone back plate and the frame for waterproofing, and the waterproof effect is not ideal. Especially in water or under a certain pressure, the connection part is prone to cracking. And when dropped to the ground, the mobile phone back plate is easy to separate, resulting in the mobile phone being out of protection. At the same time, independent waterproof parts are provided for the mobile phone charging port and the mobile phone mute key, with many parts. Summary of the Utility Model

The soft rubber sleeve extends towards the back of the mobile phone to connect the back plate and the camera protection plate;

[0008] The hard rubber inner frame has a first waterproof ring and a second waterproof ring protruding from the outer surface of its frame body. The soft rubber sleeve has a first waterproof groove for the first waterproof ring to be embedded and a second waterproof groove for the second waterproof ring to be embedded;

[0009] There is a buckling groove with an upward notch between the first waterproof ring and the frame body. The soft rubber sleeve extends towards the front of the mobile phone to form buckling teeth embedded in the buckling groove.

[0010] Specifically, the integral molding of the outer frame means that a soft rubber sleeve is injection-molded by arranging a back plate and a camera protection plate in an injection mold.

[0011] Specifically, both the back plate and the camera protection plate are made of transparent hard plastic.

[0012] Specifically, the first waterproof ring and the second waterproof ring are parallel to each other.

[0013] Specifically, from the notch to the bottom of the first waterproof groove, the groove diameter gradually increases and then gradually decreases, and the ring diameter of the first waterproof ring changes synchronously.

[0014] Specifically, the second waterproof groove is formed by expanding from a groove to one side. Among them, the groove body of the groove is embedded in the bottom of the frame body, and the expanded part of the groove is embedded in the second waterproof ring.

[0015] Specifically, at the positions corresponding to the mobile phone mute key and the mobile phone charging port, the hard rubber inner frame is respectively provided with a first through hole and a second through hole, and the soft rubber sleeve is respectively provided with a first waterproof plug passing through the first through hole and contacting the mute key and a second waterproof plug passing through the second through hole and blocking the mobile phone charging port.

[0016] Specifically, a circle of hollow holes is formed by hollowing out the periphery of the first waterproof plug and the second waterproof plug of the soft rubber sleeve, and the hard rubber inner frame is provided with plugging blocks inserted into the hollow holes.

[0017] Specifically, at the mobile phone speaker hole, the hard rubber inner frame is provided with a sound outlet hole corresponding to the speaker hole and a water isolation film arranged on the inner side of the hard rubber inner frame to cover the sound outlet hole.

[0018] Specifically, an auxiliary edge extends from one edge of the hard rubber inner frame towards the front of the mobile phone.

[0019] The technical solution provided by the present utility model has the following advantages compared with the prior art: By using an integrally formed outer frame, the problem of unsatisfactory waterproof effect between the back plate and the frame is avoided, the structure is simplified, and a matching waterproof strip and waterproof groove are provided. The edge of the soft colloid is reversely buckled with the hard rubber inner frame, taking into account airtight waterproofing and tight fixing. As the water pressure increases, the connection becomes tighter and the waterproof airtight effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

The soft rubber sleeve 30 is provided with a wedge-shaped cross protrusion 36 that passes through the third through hole 18 inwardly to contact the mobile phone control keys. The mobile phone control keys include volume up / down keys and a power on / off key.

[0036] Continue as Figure 2 and Figure 4 As shown, at the corresponding position of the mobile phone charging port, the hard rubber inner frame 10 is provided with a second through hole 17. The soft rubber sleeve 30 is provided with a second waterproof plug 34 protruding from its inner side wall. The second waterproof plug 34 is inserted into the second through hole 17 to block the mobile phone charging port. The soft rubber sleeve 30 is hollowed out around the first waterproof plug 33 and the second waterproof plug 34 to form a circle of hollow holes 70. The hard rubber inner frame 10 is provided with a stuffing block 80 inserted into the hollow holes 70.

[0037] Continue as Figure 2 As shown, at the mobile phone speaker hole, the hard rubber inner frame 10 is provided with a sound outlet hole 19 corresponding to the speaker hole and a water isolation film 60 covering the sound outlet hole 19 on the inner side of the hard rubber inner frame 10.
