Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] Example

[0020] Please refer to Figure 1 - Figure 4 As shown, the utility model provides a mobile hard disk with good anti-fall effect, including a bottom shell 1 and an upper cover 2. Internal shockproof pads 6 are laid on the inner side walls of the bottom shell 1 and the upper cover 2. The internal shockproof pads 6 are in contact with the side of the mobile hard disk. A convex plate 5 is formed on the lower surface of the upper cover 2. Corner buffer pads 7 are arranged at the corners of the bottom shell 1 and the upper cover 2. The corner buffer pads 7 are used to reduce the impact force when the corners of the bottom shell 1 and the upper cover 2 collide. Shock-absorbing rubber 9 is arranged on the lower surface of the bottom shell 1 and the upper surface of the upper cover 2. The shock-absorbing rubber 9 and the corner buffer pad 7 cooperate to ensure that when the device falls, the shock-absorbing rubber 9 or the edge The corner buffer pad 7 is in contact with the ground first, and the upper cover 2 and the bottom shell 1 are placed in direct contact with the ground. A card slot 4 is provided on the bottom shell 1, and the convex plate 5 can be inserted into the card slot 4 to prevent the device from being misaligned in directions other than the up and down direction after the device is assembled. A plug through hole 8 is provided on the front side wall of the bottom shell 1 and the upper cover 2. The plug through hole 8 is composed of a rectangular through groove provided on the front side of the bottom shell 1 and the upper cover 2. A fixing bolt 3 is passed through the upper cover 2, and a corresponding threaded hole is provided on the bottom shell 1. The fixing bolt 3 is screwed in correspondence with the threaded hole, and the convex plate 5 and the card slot 4 make the device structure more stable;

[0021] When installing a mobile hard disk, place the mobile hard disk inside the bottom case 1, make the side of the mobile hard disk fit in contact with the internal shockproof pad 6, align the socket on the mobile hard disk with the plug through hole 8, cover the upper cover 2, align the convex plate 5 on the upper cover 2 with the card slot 4, insert the convex plate 5 into the card slot 4, and then use the fixing bolts 3 to connect and fix the upper cover 2 and the bottom case 1;

[0022] like Figure 1 - Figure 4As shown, an upper cover 2 is arranged above the bottom shell 1, and a left-right symmetrical fixed block 10 is arranged in the middle of the front side of the upper cover 2, a fixed shaft 11 is arranged between the fixed blocks 10, a rotating connector 15 is sleeved on the fixed shaft 11, and the rotating connector 15 can rotate along the fixed shaft 11, and a sealing plate 16 is connected below the rotating connector 15, and a sealing gasket with a specification slightly smaller than the plug through hole 8 is arranged on the inner side of the sealing plate 16, so as to facilitate the plug through hole 8 to be blocked, and a left-right symmetrical limiting block 14 is arranged on the inner side of the fixed block 10, and two left-right symmetrical groups of retaining rings 12 are fixedly arranged on the fixed shaft 11, and a torsion spring 13 is arranged between each group of retaining rings 12, and the retaining ring 12 is used to prevent the torsion spring 13 from sliding, and the torsion spring 13 is sleeved on the shaft body of the fixed shaft 11, and the upper end of the torsion spring 13 is clamped in the limiting block 14 to block the torsion spring 13, and the lower end of the torsion spring 13 contacts the front side of the sealing plate 16 to provide torque to the sealing plate 16;

[0023] When inserting the plug, the sealing plate 16 is rotated upward, and the sealing plate 16 and the rotating connector 15 rotate along the fixed shaft 11. The lower end of the torsion spring 13 is deformed by the thrust, and the upper end of the torsion spring 13 is blocked by the limit block 14, so that the torsion spring 13 is stressed until the sealing plate 16 does not block the plug insertion. After the plug is unplugged, the force of the torsion spring 13 is applied to the sealing plate 16, so that the sealing plate 16 rotates in the opposite direction to seal the plug through the hole 8;

[0024] Specific working principle:

[0025] When using the device, first rotate the sealing plate 16 upward, the sealing plate 16 and the rotating connector 15 rotate along the fixed shaft 11, the lower end of the torsion spring 13 is pushed, and the upper end of the torsion spring 13 is blocked by the limit block 14. At this time, the torsion spring 13 has stress, and the sealing plate 16 continues to be rotated until the sealing plate 16 does not block the insertion of the plug, and then the wipe back plug is inserted. After the use is completed and the plug is unplugged, the force of the torsion spring 13 is applied to the sealing plate 16, so that the sealing plate 16 rotates in the opposite direction to seal the plug through the hole 8.
