Specific embodiment
As illustrated in fig. 1-3, a kind of security protection USB flash disk that an embodiment of the present invention provides comprising 1 He of inner housing
Outer housing 2.One end of the inner housing 1 is equipped with data-interface 11, is equipped with circuit board in the inner housing 1, the circuit board with
The data-interface 11 is electrically connected.In the present embodiment, the data-interface 11 is USB2.0 interface, in other embodiments
In, the data-interface 11 can be in Type A interface, Type C interface, Lightning interface or Micro USB interface
It is a kind of.The outer housing 2 includes protective shell 21, cavity 22 and buffer unit.The protective shell 21 is enclosed by metal plate to be set, and
Substantially rectangular tubular.The two sides of the protective shell 21 are equipped with striped 211, and the striped 211 is for improving the protective shell
The friction of 21 two sides facilitates user to grab the protective shell 21.
As illustrated in fig. 1-3, the cavity 22 is perforation, and is matched with 1 shape of inner housing.The buffer part
Between the cavity 22 and the protective shell 21, the inner housing 1 is removably connected in the cavity 22 part, described
Buffer unit includes foam-rubber cushion 23 and buffer board, and the foam-rubber cushion 23 is located at the horizontal two sides of the inner housing 1, the buffer board position
Above and below the inner housing 1, the buffer board includes contact surface 24 and spring part 25, the contact surface 24 with it is described
Inner housing 1 is in contact, and the spring part 25 is between the contact surface 24 and protective shell 21, the foam-rubber cushion 23 and described slow
Punching can effectively improve the impact resistance of USB flash disk.Shock absorption strip 26, the shock absorption strip 26 are equipped between two neighboring spring part 25
It is connected with the contact surface 24 and the metal plate, the shock absorption strip 26 is in addition to reinforcing the contact surface 24 and the protective shell 21
Between connection outside, can also further increase the buffering effect of the buffer board, reduce when USB flash disk is fallen external impact force to institute
State the influence of circuit board.
As shown in figures 1-6, the top of the protective shell 21 is equipped with the through-hole 27 of strip, the top of the inner housing 1
Equipped with reducible positive stop key 12, the positive stop key 12 can in the through-hole 27 toward the data-interface 11 direction back and forth
It is mobile.When user pushes the positive stop key 12 towards the direction of the data-interface 11, the data-interface 11 is from the chamber
It is stretched out in body 22, when user pushes the positive stop key 12 towards the opposite direction of the data-interface 11, the data-interface
