The invention discloses an external oil tank of a helicopter, and relates to the technical field of helicopter plug-in. The external oil tank comprises an oil tank body, the lower surface of the oil tank body is fixedly connected with a base, the upper surface of the oil tank body is fixedly connected with a mounting seat, the side wall of the mounting seat is fixedly connected with a short wing through a clamping mechanism, the side wall of the mounting seat is fixedly connected with two symmetrically-arranged insertion rods, and the side wall of the short wing is provided with insertion grooves matched with the insertion rods; the insertion rods extend into the insertion grooves and are slidably connected with the insertion grooves; a through groove is formed in the upper surface of the short wing, a sliding block is slidably connected into the through groove, a pressing plate is fixedly connected to one end of the sliding block, a mounting groove is formed in the upper surface of the part, extending into the short wing, of the insertion rod, a clamping block is slidably connected into the mounting groove, and a compression spring is arranged on the inner side wall of the mounting groove. The problems that an existing helicopter externally-hung oil tank is difficult to disassemble, overhaul and replace, most of existing oil tanks are difficult to carry out low-oil early warning, and when the oil amount is too low, it is difficult to give an alarm to remind refueling treatment are solved.

    本发明公开了一种直升机外挂油箱,涉及直升机外挂技术领域。本发明包括油箱本体,油箱本体的下表面固定连接有底座,油箱本体的上表面固定连接有安装座,安装座的侧壁通过卡接机构固定连接有短翼,所述安装座的侧壁固定连接有连个对称设置的插杆,短翼侧壁开设有与插杆匹配设置的插槽,插杆伸入插槽内并与其滑动连接,短翼的上表面开设有通槽,通槽内滑动连接有滑块,滑块的一端固定连接有压板,插杆伸入短翼部分上表面开设有安装槽,安装槽内滑动连接有卡块,安装槽内侧壁设置有压缩弹簧。本发明解决了现有的一种直升机外挂油箱难以对其进行拆卸检修更换,以及现有的油箱大多难以进行低油预警,当油量过低时难以报警提醒进行加油处理的问题。
