Retractable projector wire harness

Abstract

The invention provides a retractable projector wire harness. The retractable projector wire harness comprises a first shell, a second shell, a first wire harness, a second wire harness and a third interface; the first shell is fixedly connected with the second shell; the first shell comprises a first shell body and a first rotating shaft; the first wire harness comprises a first interface and a first wire body; one end of the first wire body is wound on the first rotating shaft; the second shell comprises a second shell body and a second rotating shaft; the second rotating shaft is arranged in the second shell and is fixedly connected with the second shell; the second wire harness comprises a second interface and a second wire body; one end of the second wire body is wound on the second rotating shaft; the third interface is arranged at one end, far away from the second shell, outside the first shell; and one end of the first wire body, one end of the second wire body and the third interface circuit are connected. According to the retractable projector wire harness designed by the invention, the wire harness is pulled when in use, and the wire harness can be automatically retracted when not in use, so that mutual conversion of signals of various joints can be realized, and the operation is convenient. The industrial production is also easy.

Description

technical field [0001] The patent of the invention belongs to the field of projector equipment, and in particular relates to a shrinkable projector wire harness. Background technique [0002] A projector is a device that projects an image or video onto a screen. A projector harness is often used to transfer data from a computer to a projector. At present, when decorating a conference room, considering that the computer may be placed in various places, one solution reserves a longer projector harness, which affects the overall appearance; the other solution is to set multiple interfaces at each location, which The scheme needs to consider the overall layout, and the cost is relatively high. Simultaneously, the computer that is used for projection, some video output port has only one, then can't see screen display when projection. Contents of the invention [0003] In view of the above problems, the present invention designs a shrinkable projector wire harness, which is c...
