[0013] Beneficial effects:

[0014] Compared with the existing technology, this durable explosion-proof mobile phone protective case has the following beneficial effects:

[0015] 1. The utility model provides a protective mechanism. The impact force at the corner of the mobile phone causes the corner plate to displace, so that the adjustment rods rotate. That is, the angle between the adjustment rods increases, so that the movable plates move away from each other, thereby squeezing the movable block, causing the return spring to be compressed and shortened.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-6 As shown, the utility model provides a technical solution: a durable explosion-proof mobile phone protective case, comprising a bottom plate 1, an inner frame 2 and an outer frame 3, the bottom ends of the inner frame 2 and the outer frame 3 are fixedly connected to the top of the bottom plate 1, and the inner frame 2 is located on the inner side of the outer frame 3, and several protective mechanisms 4 are provided at the top of the bottom plate 1, the protective mechanisms 4 are all located between the inner frame 2 and the outer frame 3, and the protective mechanisms 4 are respectively located at the corners of the outer frame 3, an anti-fall frame 5 is movably connected between the inner frame 2 and the outer frame 3, and adjustment mechanisms 6 are provided on both sides of the protective mechanism 4, the top of the adjustment mechanism 6 is fixedly connected to the bottom end of the anti-fall frame 5, and the adjustment mechanism 6 is located between the inner frame 2 and the outer frame 3.

[0026] like Figure 1 、 Figure 2 、 Figure 4、 Figure 5 and Figure 6 As shown, the protective mechanism 4 includes a corner pad 401, a corner plate 402, an adjustment rod 403 and a movable plate 404. The adjustment rod 403 and the movable plate 404 are symmetrically arranged. One end of the adjustment rod 403 is movably connected to the rear side of the corner plate 402 through a rotating shaft, and the other end of the adjustment rod 403 is movably connected to the front side of the movable plate 404 through a rotating shaft. The corner plate 402 is movably connected to the inner side of the corner pad 401, and the bottom end of the corner pad 401 is fixedly connected to the top of the bottom plate 1, and the corner pad 401 is located at the corner of the inner frame 2. The movable plate 404 is movably connected to the inside of the frame wall of the outer frame 3. The protective mechanism 4 also includes a moving block 405 and a return spring 406. The moving block 405 and the return spring 406 are symmetrically arranged. The moving block 405 is movably connected to the inside of the frame wall of the outer frame 3. One end of the return spring 406 is fixedly connected to one end of the moving block 405, and the other end of the return spring 406 is fixedly connected to the inside of the frame wall of the outer frame 3. The moving plate 404 is located on the opposite side of the moving block 405, and the opposite sides of the moving plate 404 and the moving block 405 are in contact with each other.

[0027] If a collision occurs at the corner of the mobile phone, the corner of the mobile phone will be displaced, and the corner of the mobile phone will squeeze the corner pad 401. The corner pad 401 is made of rubber and can absorb part of the impact force at the corner of the mobile phone. In addition, the impact force at the corner of the mobile phone causes the corner plate 402 to be displaced, causing the adjustment rod 403 to rotate, that is, the angle between the adjustment rods 403 increases, causing the movable plates 404 to move away from each other, thereby squeezing the movable block 405, causing the return spring 406 to be compressed and shortened. This process can absorb most of the energy at the corner of the mobile phone, thereby protecting the mobile phone and absorbing the impact force caused by the mobile phone being dropped or exploded.

[0028] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the adjustment mechanism 6 includes a connecting plate 601, a moving rod 602, a compression spring 603 and a support block 604. The top of the moving rod 602 is fixedly connected to the bottom end of the connecting plate 601, and the bottom end of the moving rod 602 is movably connected to the inside of the support block 604. The compression spring 603 is sleeved on the outside of the moving rod 602. The top of the compression spring 603 is fixedly connected to the bottom end of the connecting plate 601, and the bottom end of the compression spring 603 is fixedly connected to the top of the support block 604. The bottom end of the support block 604 is fixedly connected to the top of the base plate 1, and the top of the connecting plate 601 is fixedly connected to the bottom end of the anti-fall frame 5. An adjusting screw 7 is provided between the inner frame 2 and the outer frame 3. The adjusting screw 7 passes through the base plate 1 and is threadedly connected to the base plate 1. The top of the adjusting screw 7 fits with the bottom end of the anti-fall frame 5.

[0029] Use a special screwdriver to turn the adjusting screw 7 to lift the anti-drop frame 5 upward so that the height of the anti-drop frame 5 is slightly higher than the height of the mobile phone plane. When the mobile phone falls face down, the anti-drop frame 5 first contacts the ground, thereby improving the protection of the mobile phone screen. Then turn the adjusting screw 7 downward, and under the action of the compression spring 603, the connecting plate 601 and the moving rod 602 are driven to move downward, thereby causing the anti-drop frame 5 to move downward.

[0030] The working principle of the present invention is as follows: when using, first, the mobile phone body is inserted into the interior of the protective case, that is, the inner side of the inner frame 2, so that the back side of the mobile phone is tightly fitted with the surface of the bottom plate 1. If the corner of the mobile phone collides, the corner of the mobile phone will be displaced, and the corner of the mobile phone will squeeze the corner pad 401. The corner pad 401 is made of rubber and can absorb part of the impact force of the corner of the mobile phone;

[0031] In addition, the impact force at the corner of the phone causes the angle plate 402 to displace, causing the adjustment rod 403 to rotate. That is, the angle between the adjustment rods 403 increases, causing the movable plates 404 to move away from each other, thereby squeezing the movable block 405, causing the return spring 406 to compress and shorten. This process can absorb most of the energy at the corner of the phone, thereby protecting the phone and absorbing the impact force caused by the phone being dropped or exploded.

[0032] In addition, by using a special screwdriver, the adjusting screw 7 is turned to lift the anti-fall frame 5 upward so that the height of the anti-fall frame 5 is slightly higher than the height of the mobile phone plane. When the mobile phone falls face down, the anti-fall frame 5 first contacts the ground, thereby improving the protection of the mobile phone screen, and turning the adjusting screw 7 downward, under the action of the compression spring 603, drives the connecting plate 601 and the moving rod 602 to move downward, thereby causing the anti-fall frame 5 to move downward.
