Description

Technical Field

[0001] The utility model relates to the technical field of power oil tanks, in particular to a quickly disassembled and assembled helicopter power oil tank. Background Art

[0002] Helicopters are divided into unmanned helicopters and manned helicopters. Unmanned helicopters have a relatively simple structure and are relatively cheap. More importantly, they do not require a launch system at all, can take off and land vertically, and can hover freely. They are also very flexible in flight and can fly at various speeds and in various flight profiles. Therefore, they are widely used in various fields. The power tank of an unmanned helicopter is installed inside the fuselage of the unmanned helicopter and is an indispensable part of the unmanned helicopter.

[0003] Most of the current helicopter power oil tanks are fixed and welded, which makes them impossible to disassemble and repair. An unmanned helicopter oil tank disclosed in application number 201922434209.X discloses that the oil tank can be disassembled by means of a mounting plate and a mounting frame, but it is locked by a bayonet. When disassembling, it is necessary to use a tool to straighten the bayonet and then pull it out, which is more troublesome. The bayonet will experience metal fatigue during the repeated bending and straightening process, resulting in breakage at the bend and failure of the bayonet. At the same time, this structure has poor stability. After the bayonet is installed, the connecting spring has elastic displacement space, which causes the oil tank to still shake. Therefore, the utility model proposes a helicopter power oil tank that can be quickly disassembled and assembled to solve the problems existing in the prior art. Utility Model Content

[0021] The elastic reset mechanism includes a through hole 10, a connecting column 11, a reset spring 12 and a rotation locking mechanism. The inner side of the retraction groove 3 is provided with a through hole 10 passing through the side of the base plate 1. The tail end of the positioning card 4 is fixedly welded with a connecting column 11. A reset spring 12 is sleeved on the connecting column 11. The reset spring is located between the inner side of the retraction groove and the tail end of the positioning card. The tail end of the connecting column 11 passes through the through hole 10 and is provided with a rotation locking mechanism, which is convenient for retracting and locking the positioning card during disassembly.

[0022] The rotation locking mechanism includes a rotating cover 13, a locking side plate 14 and an adapting slot 15.
