Detailed Description

In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-6, the present invention provides a coded lock type memory, which comprises a memory, a locking structure 3 and a housing 2, wherein the memory is movably disposed inside the housing 2, the locking structure 3 is disposed on the outer surface of the housing 2 to control the protrusion member 1 of the memory to extend and retract; the locking structure 3 comprises a pushing block 31, a locking rod 34 and a rotating wheel, the pushing block 31 and the rotating wheel are arranged on two adjacent side faces of the shell, a clamping groove is formed in the rotating wheel, the locking rod 34 is contained in the clamping groove, a limiting block 35 is arranged on the locking rod 34, and one end of the locking rod 34 is fixedly connected with the pushing block 31 through a connecting rod 36. In the embodiment, the locking structure is arranged to limit the movement of the push block, so that the movement of the push block is controlled by the locking structure, the push block is connected with the memory to finally control the movement of the memory, and when the protruding part of the memory does not extend out, no way is naturally available for reading or storing data, so that the safety of data information in the memory is ensured.

The present application takes a usb disk as a specific embodiment for specific description: in order to achieve the purpose, the number of the rotating wheels is three, the rotating wheels comprise a number wheel 32 and a clamping wheel 33, the number wheel 32 is connected with the clamping wheel 33 through gears, clamping grooves are formed in the clamping wheel 33, the number wheel 32 is evenly divided into 10 areas, and the 10 areas correspond to numbers marked with 0-9 respectively.

Particularly, the number wheel of the present application adopts a wheel type structure, that is, the number wheel can be divided into a numerical portion 38 and a gear portion 39, one side of the gear portion 39 connected with the numerical portion 38 is provided with a steel ball 37, the steel ball 37 is movably arranged on the gear portion 39, can freely rotate but cannot fall off from the gear portion 39, and the bottom of the steel ball is further provided with a spring, so that the steel ball can move downwards to a certain extent and can retract into the gear portion; the inner side of the numerical part 38 is provided with grooves matched with the steel balls, the outer surface of the numerical part is provided with 10 numbers of 0-9, the number of the grooves is the same as that of the steel balls, the number of the grooves is 10, and the positions of the grooves and the numbers of the outer surface are matched.

Be equipped with stopper 35 on the locking lever 34, the volume of stopper 35 is less than the size of draw-in groove, stopper 35 is equipped with a plurality ofly altogether, a plurality of stoppers are in same straight line, it is more specific, the volume of stopper is less than the draw-in groove, just so can ensure that the stopper can go deep into in the draw-in groove, set up the stopper simultaneously on a straight line, just right with the draw-in groove, the continuity of motion has been ensured like this at the in-process of motion, do not take over in order to guarantee the motion of stopper simultaneously, set up the stopper laminating in other than the card wheel very much, the distance of slider motion is no less than to the length of.

The upper surface of the shell 2 is provided with a sliding chute 21, a push block 31 is arranged on the sliding chute 21, the push block 31 is fixedly connected with the memory, the front end of the push block 31 is provided with a connecting rod 36, the connecting rod 36 is fixedly connected with a lock rod 34, and when the push block 31 moves, a protruding part for pushing the memory extends out; one end of the shell 2 is also provided with a drawing hole 4, and the drawing hole 4 is positioned at the tail end of the shell 2.

The utility model discloses a theory of operation is: when the input password is correct, the clamping grooves on all the clamping wheels are positioned on the same straight line and are parallel to the straight line where the limiting block of the lock rod is positioned, the pushing block is pushed, the limiting block penetrates through the clamping grooves, and the protruding part of the memory extends out, so that data interaction is performed on the memory; when not using, shrink into the casing with the protrusion earlier in, then dial indiscriminate password, because the structure setting of card wheel, the draw-in groove can't be passed to the stopper, and the protrusion is fixed promptly, has guaranteed information security.

Under normal conditions, the groove of the numerical wheel is matched with the steel ball, and the gear part can be driven to rotate together when the numerical wheel is rotated; when needs change password, at first need guarantee that the protrusion is in the state of stretching out, stir the numerical value portion of digit wheel this moment, because gear portion and card wheel meshing are in the same place, consequently can't rotate, but because the steel ball roll connection between numerical value portion and the gear portion, the steel ball is under the extrusion that receives numerical value portion internal surface this moment, break away from the scope of recess, compressed the inside to gear portion, when next recess appears, the steel ball is by the spring reset, enter into the within range of recess again, cycle is reciprocal according to this, thereby can carry out the rotation of numerical value portion, thereby change the password.

The utility model has the advantages that:

1) the mechanical structure lock is adopted, the locking structure is simple, the long-time operation can be realized, and the long-time safety protection of the memory is ensured;

2) the password can be freely replaced, so that the safety can be greatly improved.

The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
