Abstract

The utility model discloses a rotary adapter and is characterized in that a cover body is internally provided with a spring plate and a female USB joint which is connected with a male USB joint by a wire; a gear is fixed to the wire close to the middle part thereof and the gear can contact with the spring plate. The utility model relates to an L-shaped rotary adapter which is a transformation device by which an infrared signal transceiver device can be connected with a PC. The female USB joint can rotate and position at 0-150 degrees as the spring plate is arranged in the cover body and the gear is sleeved to the wire and a 90-degree angle formed by the male and female USB joints enables signals from the infrared signal transceiver device to cover a wider area and thoroughly eliminates signal dead corner. The utility model also has small volume, is portable and applicable for various desktop PCs and notebooks for adopting standard USB interfaces and is a new partner for wireless and movable office.

Description

A kind of rotary adapter

Technical field:

Utility model relates to the technical field of computer fittings, a kind of specifically rotary adapter.

Background technology:

Raising day by day along with living standard; the popularity rate of personal desktop PC improves greatly; even portable notebook computer also is extensive use of by people; follow the fast development of scientific and technological level; the controlled in wireless technology is being applied on all kinds of PCs; for example wireless mouse and Wireless Keyboard; this series products is except installing the infra-red signal R-T unit at mouse and keyboard; also need on PC, install a far infrared transceiver; to arrive the purpose of data signals transmitted in both directions; this type of device generally all is outer being connected on the PC; it can be connected with PC by standard USB interface; the external far infrared transceiver of being sold in the market generally all into strips; just passable during use as long as the strip far infrared transceiver is vertically inserted the USB interface place of PC rear end, but the transmitting-receiving port direction is changeless, because the reason of angle; in use run into the problem at signal region dead angle, cause the interruption of using signal through regular meeting.

Summary of the invention:

The purpose of this utility model is to provide a kind of rotary adapter, and it can solve the problem at signal region dead angle in the prior art.

To achieve these goals, the technical solution of the utility model is: a kind of rotary adapter, it mainly comprises lid up and down, with the USB male that matches with lid, USB female, it is characterized in that: be equiped with a shell fragment and a USB female in the lid, this USB female is connected with the USB male by cable, and cable is fixed with a gear near center, and this gear can touch shell fragment.

The utility model is a kind of L type rotary type adapter, it is a kind of switching device, the infra-red signal R-T unit can be connected with PC by it, because it has installed shell fragment in lid, and be fixed with a gear at the cable place, make the USB female can be between 0 °～150 ° random positioning of rotating, moreover, the USB male of adapter and the angle of USB female are approximated to 90 °, the signal overlay area of the feasible infra-red signal R-T unit that is attached thereto is wider, thoroughly solved the problem at original signal dead angle, and the utility model volume is small and exquisite, be convenient for carrying, and the employing standard USB interface, be applicable to various desktop PCs and each notebook computer, be a kind of new companion of wireless portable office.
