[0058] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0059] Example

[0060] A specific embodiment of the utility model discloses a waterproof case, such as Figure 1 and Figure 2As shown, a storage cavity, a sealing groove 1, a sealing strip 2, a pressing protrusion 3 and a panel; a plurality of panels are hermetically connected to enclose a storage cavity; two panels connected to each other are set to be a first panel 4 and a second panel 5; the sealing groove 1 is arranged on the first panel 4; the pressing protrusion 3 is arranged on the second panel 5; the pressing protrusion 3 extends into the sealing groove 1 to limit the sealing strip 2 and press it into the sealing groove 1.

[0061] In this embodiment, the pressing protrusion 3 limits the sealing strip 2 and presses it in the sealing groove 1, so that the sealing strip 2 reaches the optimal compression amount, blocks water and other foreign substances from entering from the gap between the two interconnected panels, and realizes complete sealing of the connection between the two panels. Under the conditions of increased immersion depth and immersion time, increased pressure on the waterproof chassis and increased pressure time, the pressing protrusion 3 always limits the sealing strip 2 and presses it in the sealing groove 1, the sealing strip 2 will not shift and still has waterproof performance, thereby ensuring the sealing effect of the waterproof chassis and thus ensuring the normal operation of the components in the storage cavity.

[0062] Furthermore, the sealing strip 2 includes a main body 21 and a through hole 22. Figure 1 and Figure 2 As shown, the main body 21 includes a fixing portion and a protrusion, and the protrusion contacts the pressing protrusion 3.

[0063] In this embodiment, the sealing strip 2 has the functions of preventing water from entering the storage cavity and electromagnetic shielding, and is made of silicone rubber material filled with aluminum silver-plated particles, which can take into account both sealing and electromagnetic shielding performance.

[0064] In this embodiment, the protrusion includes a first protrusion 211 and / or a second protrusion 212. The first protrusion 211 is used for electromagnetic shielding; the second protrusion 212 is used to prevent water from entering the storage chamber; both the first protrusion 211 and the second protrusion 212 can contact the pressing protrusion 3. The first protrusion 211 is used for electromagnetic shielding, and the material of the first protrusion 211 includes conductive rubber. The second protrusion 212 is used for waterproofing, and the material of the second protrusion 212 includes waterproof silicone. Or the first protrusion 211 is used to prevent water from entering the storage chamber, and the second protrusion (212) is used for electromagnetic shielding. Or the first protrusion 211 and the second protrusion (212) are both used to prevent water from entering the storage chamber and for electromagnetic shielding.

[0065] In this embodiment, if Figure 1 and Figure 2As shown, the through hole 22 extends along the length direction of the sealing strip 2 and penetrates the sealing strip 2. The through hole 22 is arranged inside the main body 21 and is located between the first protrusion 211 and the second protrusion 212. The through hole 22 enables the sealing strip 2 to be deformed in the sealing groove 1 to be more suitable for the shape of the sealing groove when being squeezed by the pressing protrusion 3, so as to be closely attached to the inner wall of the sealing groove 1 to achieve a sealing effect.

[0066] In this embodiment, if Figure 2 As shown, the first protrusion 211 and the second protrusion 212 are both convex arc structures. The main body 21 also includes an inner concave portion 213, and the inner concave portion 213 is arranged in the middle of the first protrusion 211 and the second protrusion 212 to facilitate the first protrusion 211 and the second protrusion 212 to deform after being squeezed by the pressing protrusion 3.

[0067] Furthermore, the sum of the heights of the clamping protrusion 3 and the sealing strip 2 when they are in a compressed state is greater than or equal to the height of the sealing groove 1. Preferably, the sum of the heights of the clamping protrusion 3 and the sealing strip 2 when they are in an optimal compression state is equal to the height of the sealing groove 1. At this time, the gap between the end faces of the two interconnected panels is the smallest, which is more conducive to sealing.

[0068] For example, the sealing strip has the best sealing effect when the compression reaches 20%, and the dimensions of the sealing strip in the uncompressed state are 1.8mm in width and 2.4mm in height. Considering the size restrictions during the installation of the sealing strip, the groove width of the sealing groove is designed to be 1.9mm and the groove depth is 1.82mm. When the pressing protrusion is fully extended into the sealing groove, the sealing strip is at the best compression amount, and the gap between the two interconnected panels is minimized.
