A disclosed anti-loosening charging gun for a new energy automobile comprises a charging gun body, a hollow shaping sleeve is fixedly connected to the upper side wall of the charging gun body, an airgroove is formed in the side wall of the charging gun body, a push plug is connected into the air groove in a sliding mode, and the air groove communicates with the interior of the hollow shaping sleeve through a guide pipe; and the push plug is elastically connected to the inner wall of the air groove through a conductive spring, two first conductive blocks are installed on the two opposite innerwalls of the air groove, and a conductive rod is arranged between the two first conductive blocks. By arranging the hollow shaping sleeve, after the charging gun body is inserted into the interface and a power supply circuit is switched on, the conductive spring is electrified to contract, and the push plug is pulled to move so as to blow air into the hollow shaping sleeve, so that the hollow shaping sleeve bulges and is in close contact with the inner wall of the interface, the charging gun connection is facilitated, and meanwhile, the charging gun can be prevented from loosening and fallingoff.
本发明公开了一种新能源汽车用防松动充电枪,包括充电枪本体,所述充电枪本体上侧壁固定连接有空心塑形套,所述充电枪本体的侧壁开设有气槽,所述气槽内每滑动连接有推塞,所述气槽通过导管与空心塑形套内部连通,且所述推塞通过导电弹簧弹性连接在气槽的内壁上,所述气槽的两个相对内壁上安装有两个第一导电块,两个所述第一导电块之间设有导电杆。本发明通过设置空心塑形套,可在将充电枪插入接口内供电电路接通后,使导电弹簧通电收缩,并拉动推塞移动从而将空气鼓入空心塑形套内,如此可使空心塑形套鼓起并与接口内壁紧密接触,既方便充电枪接口,同时又可防止充电枪松动、脱落。
