The plug supporting seat 7 may have four supporting bodies 13, where the supporting bodies 13 have arc surfaces corresponding to and contacting with the plug 15, and two of the supporting bodies are provided with clamping protrusions 21 for clamping the plug 15.
The top of the handle 9 may be hinged with a fixing rod for mounting in a fixing clip groove 19 on the shore power hookup 16.
The plug support seat 7 and the function seat 8 are relatively static in a normal state, and the function seat 8 can slide up and down on the guide rail of the guide rail seat 3; when the function seat 8 slides to the lowest end of the guide rail, namely contacts with the track limiting block 2, at the moment, the sliding rod 18 on the function seat 8 also slides to the end of the sliding groove 17 on the handle 9, after the plug 15 is placed on the plug support seat 7, the handle 9 is pushed to enable the plug 15 to move upwards along the guide rail, finally the plug 15 is inserted into the socket of the shore power box 16, after the plug is inserted into place, the handle 9 is perpendicular to the base 1, the sliding rod 18 on the function seat 8 also slides to the other end of the sliding groove 17 on the handle 9, and at the moment, the handle 9 can be fixed on the shore power box 16 by adopting a common means in the prior art, for example, a fixing rod hinged at the head of the handle 9 is screwed into a fixing clamping groove 19 on the shore power box 16, so that the handle 9 does not rotate outwards, and further the plug 15 is kept stable after being inserted into the socket of the shore power box 16, in the process, the stroke of the sliding block under the function seat 8 on the guide rail is the stroke of the sliding rod 18 in the sliding groove, and the process is obviously more labor-saving and the inserting efficiency is higher than that when the plug 15 is directly inserted into the socket.
Under the condition that the plug 15 is normally pulled out, the handle 9 is pulled outwards after a fixed rod hinged to the handle 9 is unlocked, the plug 15 can be pulled out together with the function seat 8 and then slides downwards along a guide rail on the guide rail seat 3 until a sliding block on the function seat 8 is contacted with the rail limiting block 2, and then the plug 15 can be taken out; when the plug 15 cannot be pulled out by a normal method in an emergency, that is, only the cable connected to the rear of the plug 15 can be pulled to pull out the plug 15, after the external force is transmitted to the cable to the plug 15 and is greater than the locking force of the forced release control block 4 to the forced release protrusion blocks 14 at the bottom of the plug support seat 7, the plug 15 slides downwards along the limit grooves 12 at two sides of the function seat 8 along with the plug support seat 7, and simultaneously, the forced release protrusion blocks 14 at the bottom of the plug support seat 7 also slide downwards along the longitudinal grooves of the forced release grooves 11, so that the forced release control block 4 compresses the springs 5 to move outwards along the transverse grooves of the forced release grooves 11, and finally the plug support seat 7 and the plug 15 slide out of the function seat 8 together to realize the forced separation function. Under the condition of normal plug-in and plug-out, the forced-release control block 4, the spring 5 and the plug supporting seat 7 are relatively static, and only when forced separation is needed under emergency conditions, the plug supporting seat 7 can slide downwards along the limit grooves 12 on two sides of the functional seat 8, so that the forced separation function is triggered.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention. The technology not related to the invention can be realized by the prior art.
