Problems solved by technology
[0003] In order to solve the problem that electric shock accidents are likely to occur in the plug-in power transmission device in the prior art, the present invention aims to provide a safe power transmission device for preventing falling off and plugging in and out. In the state of no power supply, only when the operator inserts the power receiving plug into the power transmission jack and rotates it at a certain angle, the power transmission jack will connect the power receiving plug to the power supply, and there will be no electric shock accident caused by foreign objects inserted into the power transmission jack

The invention discloses an anti-drop safe-plugging power transmission device. The device comprises a power transmission socket and a power receiving plug; the power transmission socket comprises a power transmission junction box and a junction box cover plate. The power receiving plug comprises a two-rod plug and a three-rod plug; a socket shaft seat and a rotary socket frame are arranged in an inner cavity of the power transmission junction box, a socket rotary opening is formed in a junction box cover plate, directional buckles are arranged in the middle of the two-rod plug and the middle ofthe three-rod plug, and the directional buckles enable the power receiving plug to be inserted into or pulled out of a power transmission jack only when the rotary socket frame is in a power-off state. According to the invention, the power transmission socket provided by the embodiment is in a power-off state in a normal state; even if a child inserts a metal conductive object into a power transmission jack, an electric shock accident of personal casualties cannot be caused; an operator only needs to insert the power receiving plug into the power transmission jack and transversely rotate thepower receiving plug, the power receiving plug can be connected with a power supply by rotating a socket frame, and the situation that the power receiving plug is separated from the power transmissionsocket cannot occur in the power-on process.
Description
technical field [0001] The invention belongs to a power transmission device, in particular to a safety power transmission device for preventing foreign matter from being inserted into a power transmission jack and causing electric shock accidents. Background technique [0002] Both the mobile power transmission socket and the fixed power transmission socket of the prior art belong to the "straight-through" power transmission socket. However, electric shock accidents caused by the insertion of foreign objects often occur in the above-mentioned "straight-through" power transmission socket, especially some underage children, driven by curiosity, insert metal conductive objects such as iron nails and iron wires into the power transmission socket, and then Electric shock accidents causing personal injury or death. Contents of the invention [0003] In order to solve the problem that electric shock accidents are likely to occur in the plug-in power transmission device in the pr...
