Description

A kind of dust-proof USB flash disk

Technical field

The utility model is related to medical instruments field, especially a kind of dust-proof USB flash disk.

Background technology

USB flash disk is a kind of people's commonly movable storage device, and traditional shape is strip, set in one end there are one USB plug is for being inserted into computer or other electronic equipments, to read or be written USB flash disk data.USB plug is the pith of USB flash disk, If there is damage will make entire USB flash disk can not normal use, so USB plug is to need position to be protected, need to prevent into Enter dust, oil stain or is magnetized.

In the prior art, entitled such as Patent No. CN 20194487：A kind of USB flash disk with silica gel sheath, technical side Case is that silica gel sheath is set to USB fabric position, at fold and can be elastic structure, by fold when needing to use The silica gel sheath of shape bounces back, and exposes USB plug, using being resetted again when finishing.The silica gel sheath of the structure exists as follows Problem, i.e., after the silica gel sheath retraction of fold its own with certain thickness, the thickness can influence USB plug cannot fully by It is inserted into computer, such computer cannot read the USB flash disk, affect the normal use of USB flash disk instead.Therefore, how can be It under the premise of USB plug can be inserted completely into computer, prevents from entering dust and oil stain, so that USB flash disk is hardly damaged as length Insoluble technical barrier since phase.

In view of the foregoing, a kind of dust-proof USB flash disk is now developed.

Utility model content

The purpose of this utility model is to overcome deficiencies in the prior art, a kind of dust-proof USB flash disk are provided, in use, hand Pushing block makes pushing block be moved backward in sliding slot, and pushing block drives sliding rack to move backward drive pair of sliding head in a pair of of limiting plate A pair of of limiting slot in move backward, sliding rack moves backward holddown spring, and spring is made to shorten, and rotating memory makes USB plug By exposing in the gap between the sheet rubber of upper and lower in U-shaped shell, the elastic force of spring itself makes sliding rack set back, Rear baffle and front apron can effectively avoid dust from entering in U-shaped shell, reversed to revolve by aforesaid operations step after use Unloading reservoir makes USB plug enter in U-shaped shell.The utility model can be effectively prevented into dust, oil stain, play every Effect from protection.

The utility model to achieve the goals above, adopts the following technical scheme that：A kind of dust-proof USB flash disk, be by：U-shaped shell, Positioning seat, rear baffle, front apron, sliding slot, memory, USB plug, spindle nose, sliding rack, plush copper, retainer ring, sheet rubber, resilient strip, Slide head, pushing block, limiting plate, limiting slot, spring, screw, link are constituted；Memory, storage are set in the U-shaped mouth of U-shaped shell USB plug is arranged in one end of device, and spindle nose, U-shaped mouth inner surface both sides respective shaft are vertically arranged in the middle part of memory upper and lower surface A pair of of positioning seat of head setting, the centrally disposed groove of positioning seat, a pair of of spindle nose are set in the groove of a pair of of positioning seat, memory with Line rotates centered on the axial line of a pair of of spindle nose, and a pair of of limiting plate is vertically arranged in the middle part of lower inner surface in U-shaped shell one side edge, Horizontal direction limiting slot, the sliding rack of the inside setting U-shaped of a pair of of limiting plate, the upper and lower of sliding rack side are set in limiting plate A pair of slide head perpendicular to sliding rack is set, and the pair of sliding head of sliding rack is set in the pair of limiting slot, sliding rack Plush copper is vertically arranged in the middle part of front end surface, plush copper periphery is arranged retainer ring, forms annular gap, U-shaped shell between plush copper and retainer ring The middle part side of middle section is threaded hole, and screw is bolted in threaded hole, between the lead screw periphery of screw and annular gap Spring is set, and the spiral shell of screw emits setting link, is arranged between U-shaped shell side a pair of limiting plate and the U-shaped bottom of U-shaped shell Rear baffle is set between the U-shaped bottom of front apron, the U-shaped shell other side and U-shaped shell, pushing block, U are set above sliding rack rear end Shape upper surface of outer cover one side edge corresponds to pushing block setting sliding slot, and sliding slot is exposed in pushing block upper end, and wavy surface, U-shaped is arranged in pushing block upper end Sliding rack U-shaped mouth in upper and lower surface be uniformly distributed rectangular sheet rubber, resilient strip is embedded in sheet rubber, elastic force Upper and lower surface of the item in the U-shaped mouth of the sliding rack of U-shaped, preset clearance between the sheet rubber of upper and lower in sliding rack, The gap, spring axial line and U-shaped shell horizontal direction axis parallel.

The utility model has the beneficial effects that：In use, hand push pushing block makes pushing block be moved backward in sliding slot, pushing block drives Sliding rack, which moves backward, drives pair of sliding head to be moved backward in a pair of of limiting slot of a pair of of limiting plate, and sliding rack moves backward Holddown spring makes spring shorten, and rotating memory makes USB plug by the seam between the sheet rubber of upper and lower in U-shaped shell Expose in gap, the elastic force of spring itself makes sliding rack set back, and rear baffle and front apron effectively can avoid dust from entering U-shaped In shell, after use, by aforesaid operations step, reversely rotating memory makes USB plug enter in U-shaped shell.

The utility model can be effectively prevented into dust, oil stain, play the role of insulation blocking.It is simple in structure, It is hardly damaged, prolongs the service life.It is simple in structure, it is skillfully constructed, light small and exquisite, small, easy to carry, production cost is low Honest and clean, this product has obtained the consistent favorable comment of users since release, is suitble to popularity application.
