The technical scheme of the automatic retractable U disk of the present invention is: comprising a base body and a USB plug arranged below the base body, a chip connected to the USB plug is arranged in the base body, and the feature is that It includes a shell and a push button, the base and the USB plug are both arranged inside the shell, the push key passes through the top of the shell and is connected to the upper end of the base, and the bottom of the shell is provided with There is an opening for the USB plug to protrude from, and support springs are provided on both sides of the opening, the upper end of the support spring is connected to the bottom of the base body, and the left and right inner walls of the shell are symmetrically provided with elastic engaging devices, The two elastic engaging devices are respectively engaged with the left and right sides of the base body.

When in use, press down the button to move the base body downward, the opening at the bottom of the shell matches the size of the USB plug, push the first half of the USB plug out of the shell from the opening at the bottom of the shell, the base body and the elastic engagement device Snap, the USB plug of the U disk is inserted into the corresponding interface of the computer. After use, press the button down, and the base body rebounds upward under the rebound force of the supporting spring, driving the USB plug of the U disk to shrink back into the casing. The envelope is movably connected with the shell, so that when the U disk is not in use, its USB plug end is located in the shell, and the USB plug will not be damaged.

As a further improvement, the elastic engaging device includes an engaging spring, an engaging strip and an engaging protrusion, and the two engaging strips are respectively connected to the left and right inner side walls of the shell through an engaging spring, so that The two engaging strips are respectively provided with engaging protrusions, and the left and right side walls of the base body are provided with a plurality of engaging grooves, and the engaging protrusions are engaged and connected with the engaging grooves.

As a further improvement, the engaging groove is an isosceles triangular groove structure, and the engaging protrusion is an isosceles triangular structure matching the engaging groove.

Press the button to push the base to move downward, push the front end of the USB plug out of the shell and connect it to the computer, the engaging grooves on both sides of the base respectively engage with the engaging protrusions, so that the base is fixed at the current position, when the U disk is used up Finally, pull out the U disk, press down the button and then release the button, the substrate will bounce up under the action of the rebound force of the supporting spring, and return to the original position, and the USB plug will retract into the shell; the engaging groove and the engaging The bumps are isosceles triangles that cooperate with each other, and the matching effect is better when the substrate is pressed down or bounced up.

As a further improvement, it also includes a cover, the cover is rotatably arranged on the outer wall of the shell, so that the opening of the shell can be opened or closed, which can further prevent dust and other sundries from entering the USB plug, and the cover is movable It is arranged on the outer wall of the shell and cannot be lost.

The beneficial effect of the invention is that the structure is simple, the use is convenient, and the USB plug of the U disk can be effectively protected.
