Abstract

The utility model relates to a multi-head dual-telescopic USB hub, comprising a shell, USB chip arranged inside the shell, a plurality of USB females and a USB pin which has a scrolling type unilateral-telescopic wire-winding device. The utility model is characterized in that: the USB chip inside the shell and every connecting circuit of USB female are respectively wound on the rotary disk of the scrolling type unilateral-telescopic wire-winding device, which is free in constriction and releasing. With the USB hub of the utility model, the user has no need to find the USB connecting wires of the surrounding devices when in use of the surrounding devices, thus, the trouble to find the connecting wire or the connecting wire is missed is avoided; and the length of the connecting wire between the surrounding devices and the computer is adjustable according to the demand, so that the connecting wire is kept in the shortest using length, avoiding the connecting wire dispersing around. When the application of the utility model is done, slightly drawing the USB female and the USB plug, the connecting wire will automatically be scrolled into the shell. The structure is simple and the practicability is great.

Description

Bull bi-directional expansion usb hub

Technical field

The utility model relates to hub, specifically, relates to and some terminals can be inserted use simultaneously, and the unidirectional Telescopic of union is in one, and use and easy to carry, a kind of bull bi-directional expansion usb hub flexibly.

Background technology

The english abbreviation of USB is UniversalSerialBus, and translating into Chinese is exactly " USB ", also claims the general series interface.

Usb hub (HUB) is a kind of box that installs the USB female seat of several or greater number, and this USB female seat quantity is then decided on the specification of inner USB chip, is equipped with power circuit and a USB plug of inserting the PC USB port.Because the peripheral device kind is more and more, application popularization adds low price, color scanner, digital camera, modulator-demodulator, PC Camera, PC Phone, Speaker...... etc. slowly become standard device, PC only provides 4 following biography ports just to seem not apply and uses, so the extension function of USB HUB has just been brought into play, can select the usb hub of 4,10 or more USB female seats according to need, want to install how many peripheral devices and can satisfy your demand.

Existing hub generally adopts a pair of plug at some long connection lines and two ends thereof, a hub can only connect the terminal of a corresponding socket, and to launch connection line in use earlier, unnecessary during use connection line is scattered everywhere, and again its coiling is shaped when depositing, thereby, use and carry equal inconvenience; Although occurred unidirectional flexible USB winder (200420043775.9) and the unidirectional flexible usb hub of scroll-type (patent No. 200420043770.6) in the market; its connection line can be according to user's needs length and arbitrarily folding and unfolding; unnecessary circuit is unlikely to be scattered; use; carry all very convenient; but along with the continuous progress of science and technology and the continual renovation of product are regenerated; because it is the version that can stretch that existing hub has only the USB plug place; in use; because the USB female seat is the not flexible of fixing; each peripheral device that is connected with computer all will be connected with the USB female seat of hub with the USB wiring; because these USB wiring that connect computer and peripheral device all are independent; usually can be lost or be can not find for the moment, be used inconvenience.And existing hub can not address this problem, and therefore, existing hub is still waiting further to improve and innovation, could adapt to the needs of existing market.

Summary of the invention

The purpose of this utility model is to provide a kind of bull bi-directional expansion usb hub, can directly connect some terminals, is user-friendly to.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of bull bi-directional expansion usb hub, it comprises shell, built-in USB chip, the some USB female seats of shell, USB plug with having the unidirectional flexible coiling apparatus of scroll-type is characterized in that: the connection line of shell internal USB chip and each USB female seat is wound on one respectively arbitrarily on the rotating disk of the unidirectional flexible coiling apparatus of scroll-type of folding and unfolding.

Beneficial effect: use this usb hub of the present utility model, the user when using peripheral device, needn't remove to seek the USB line of peripheral device equipment, the worries that can not find or lose connecting line have for the moment been exempted, and peripheral device is to the connecting line length between the computer, can be as required and arbitrarily folding and unfolding, remain the shortest, be unlikely to make connection line to be scattered everywhere, need only spur the USB female seat gently after finishing using and USB plug can be involved in the shell automatically, simple in structure, applicability is strong.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment, wherein: 1-shell, 2-USB plug, the unidirectional flexible coiling apparatus of 3-scroll-type, 4-USB female seat, 5-connection line.

Embodiment

The utility model embodiment is referring to Fig. 1, a kind of bull bi-directional expansion usb hub, it comprises shell 1, the built-in USB chip of shell, 3 USB female seats, USB plug 2 with having the unidirectional flexible coiling apparatus 3 of scroll-type is characterized in that: the USB chip that shell is built-in and the connection line 5 of each USB female seat are wound on one respectively arbitrarily on the rotating disk of the unidirectional flexible coiling apparatus 3 of scroll-type of folding and unfolding.

The unidirectional flexible reel line apparatus 3 of scroll-type is prior aries, it comprise loam cake, lower cover and between axis, also comprise the rotating disk that rotates around axis, in rotating disk, be wound with the scroll-type spring leaf, and the ball that is provided with track and is mated on its surface; Be wound with the connection line 5 of arbitrarily folding and unfolding on rotating disk, the one end is connected with USB female seat 4, and the other end is connected with the USB chip; The quantity of USB female seat 4 is three, and the quantity of USB plug 2 is one, is arranged at respectively on the side all around of shell 1.

The unidirectional flexible usb hub of the scroll-type of the utility model embodiment in use, USB plug 2 is inserted the USB port of PC, needs according to the user can insert three terminals simultaneously on USB female seat 4, and the length of the connection line 5 of the connection line 5 of USB female seat and USB plug can be stretched to a certain degree and automatic location, when depositing, only need spur plug gently and automatically spiral reset; Use, deposit all very convenient, and applied widely, good reliability, rational in infrastructure.

Claims (1)

1. bull bi-directional expansion usb hub, it comprises USB chip, the some USB female seats that shell, shell are built-in and has the USB plug of the unidirectional flexible coiling apparatus of scroll-type, it is characterized in that; The connection line of shell internal USB chip and each USB female seat is wound on one respectively arbitrarily on the rotating disk of the unidirectional flexible coiling apparatus of scroll-type of folding and unfolding.
