Abstract

The utility model discloses a retractable USB flash drive. The USB flash drive is composed of a housing, a USB flash drive main body and a push rod, and is characterized in that the housing is bar-shaped and is provided with an opening at an upper end; two identical elastic grooves which project outwards are disposed in an upper part of the front face of the housing; a funnel-shaped USB flash drive limiting retraction groove are disposed at a lower end of the inside of the housing; the USB flash drive main body is built in the housing; a port at the lower end of the USB flash drive penetrates through the USB flash drive limiting retraction groove; a baffle is arranged in the middle of the USB flash drive; the USB flash drive is sleeved with a rectangular compression spring at the part between the baffler and the USB flash drive limiting retraction groove; the push rod, via the upper end opening of the housing, enters into the housing and presses against the upper end of the USB flash drive main body; a projection part is disposed on the front face of the push rod; and when the USB port is retracted into the housing, the upper part of the push rod extends out from the upper end opening of the housing, and the projection part of the push rod is positioned in one elastic groove. The USB flash drive is retractable, does not need a separate cap, and thus the retractable USB flash drive solves problems of USB flash drive pollution and damage caused by easy loss of the cap of the USB flash drive, and the retractable USB flash drive has strong practicality.

Description

A kind of scalable USB flash disk

Technical field

The utility model relates to electronic technology field, particularly a kind of scalable USB flash disk.

Background technology

USB flash disk is as memory device, and its profile, structure have a variety of, and the block of most USB flash disks and disk body are designs separately, during use, need take off block, USB interface could be inserted on power supply, after being finished, then will blocking a shot and cover on USB interface; In use, the block of USB flash disk is easily lost, and loses the protection of block, on USB interface, easily is infected with dust, and USB flash disk is contaminated and damage easily, greatly reduces the useful life of USB flash disk.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of scalable USB flash disk, and this USB flash disk, when not using state, can be hidden interface in the enclosure, effectively protect USB flash disk, and this USB flash disk is simple in structure, light and handy exquisite.

The technical scheme that the utility model addresses the above problem is as follows:

A kind of scalable USB flash disk, this USB flash disk is comprised of housing, USB flash disk main body and push rod, it is characterized in that:

Described housing is bar shaped, there is an opening upper end, the top in housing front is provided with the elasticity groove of two identical outside protuberances, two elasticity grooves are positioned on same vertical axis, and the spacing of two elasticity grooves is more than or equal to the length held that USB flash disk inserts USB interface, the interior lower end of housing is one to be funnelform USB flash disk limit telescopic groove.

Described USB flash disk main body is built in housing, the socket of USB flash disk lower end passes USB flash disk limit telescopic groove just, the middle part of USB flash disk is provided with a baffler, the part cover of USB flash disk between baffler and USB flash disk limit telescopic groove has a rectangle Compress Spring, the thickness of rectangle Compress Spring is less than the outer width of baffler, is greater than the width of rebate of USB flash disk limit telescopic groove.

Described push rod is through upper end that the upper end open of housing enters enclosure interior and withstands the USB flash disk main body, the front of push rod is provided with a lug boss, the size of lug boss is slightly less than the size of the protuberance of two elasticity grooves, when the USB flash disk socket is contracted in housing, the top of push rod is stretched out by the upper end open of housing, the boss of push rod is in the elasticity groove of housing upside, and when the USB flash disk socket stretched out fully, the boss of push rod was in the elasticity groove of housing downside.

Compared with prior art, the utlity model has following advantage:

The utility model utilizes the scalable principle of spring, is that USB flash disk is flexible in housing, does not need independently to block a shot, and the block that has solved USB flash disk is easily lost the problem that causes USB flash disk to pollute and damage, practical.

The accompanying drawing explanation

Fig. 1 is the cross-section structure view of USB flash disk plug contraction state of a specific embodiment of a kind of scalable USB flash disk described in the utility model; Fig. 2 is the cross-section structure view that the USB flash disk plug stretches out state.

Embodiment

The utility model is described in further detail below in conjunction with embodiment shown in the drawings.

As shown in Figure 1 and Figure 2, this example is a kind of scalable USB flash disk, this USB flash disk is comprised of housing 1, USB flash disk main body 2 and push rod 5, housing 1 is bar shaped, there is an opening upper end, and

elasticity groove

3 and 4, two elasticity grooves of groove that the top in housing 1 front is provided with two identical outside protuberances are positioned on same vertical axis, and the spacing of two elasticity grooves is more than or equal to the length held that USB flash disk inserts USB interface, the interior lower end of housing 1 is one to be funnelform USB flash disk limit telescopic groove 6.

USB flash disk main body 2 is built in housing 1, the socket of USB flash disk lower end passes USB flash disk limit telescopic groove 6 just, the middle part of USB flash disk is provided with a baffler 7, the part cover of USB flash disk between baffler 7 and USB flash disk limit telescopic groove 6 has a rectangle Compress Spring 8, the thickness of rectangle Compress Spring 8 is less than the outer width of baffler 7, is greater than the width of rebate of USB flash disk limit telescopic groove 6;

Push rod 5 enters through the upper end open of housing 1 upper end that housing 1 is inner and withstand USB flash disk main body 2, the front of push rod 5 is provided with a lug boss, the size of lug boss is slightly less than the size of the protuberance of two elasticity grooves, when the USB flash disk socket is contracted to housing 1 when interior, the top of push rod 5 is stretched out by the upper end open of housing 1, the boss of push rod 5 is in elasticity groove 3, and when the USB flash disk socket stretched out fully, the boss of push rod 5 was in elasticity groove 4.

During use, to side direction in housing, press the lug boss of the push rod 5 that is positioned at elasticity groove 3 inside, make lug boss break away from elasticity groove 3, pressing simultaneously push rod 5 promotes downwards, push rod 5 enters through the upper end open of housing 1 upper end that housing 1 is inner and withstand USB flash disk main body 2, utilize between USB flash disk and USB flash disk limit telescopic groove 6 movingly to lower compression rectangle Compress Spring 8, when the lug boss of push rod 5 slips into downwards in elasticity groove 4, the USB flash disk socket stretches out fully, now USB flash disk can be connected to the apparatus such as computer reading out data; If finishing using, USB flash disk wants to pack up socket, can press to side direction in housing the lug boss of the push rod 5 that is positioned at elasticity groove 4 inside, make lug boss break away from elasticity groove 4, rectangle Compress Spring 8 pops up, and withstand and intercept version 7, and upwards promote push rod 5 by baffler 7, when the lug boss of push rod 5 upwards slips in elasticity groove 3 from elasticity groove 4, the USB flash disk socket is contracted in USB flash disk limit telescopic groove 6 fully.
