Description

Technical Field

[0001] The utility model relates to the field of helicopters, in particular to a quick-detachable connection structure and a helicopter. Background Art

[0002] The existing helicopter includes a body and a casing. The casing is fixed to the body to protect the body. A battery is arranged in the body to provide power. When the helicopter is in use, the casing needs to be frequently disassembled to assemble the battery and to repair and maintain the body. Therefore, the existing casing is fixed to the body in a detachable manner. After a cylindrical rod is arranged on the body to penetrate the casing, a rubber ring is sleeved on the cylindrical rod to fix it. When disassembling, the rubber ring is removed to complete the disassembly. However, in order to ensure that the casing is reliably fixed to the casing when the transport helicopter and the helicopter are flying, a large friction force must exist between the rubber ring and the cylindrical rod, forming a large disassembly resistance. Moreover, the rubber ring is prone to cracking and deterioration of elasticity after frequent disassembly and use, and becomes a consumable, resulting in inconvenience in disassembly.

[0039] The working principle of the quick-release connection structure 10 is as follows:

[0040] Connection: Insert the second connecting component 13 into the first connecting component 11, the movable part 155 is located at the second groove 1511 and the through hole 131, and the elastic part 153 is in a compressed state. When the through hole 131 reaches the position of the first groove 113, the elastic part 153 pushes the pressing part 151 to move away from the first connecting component 11, and the pressing part 151 pushes the movable part 155 to move toward the first groove 113 until the movable part 155 is located between the first groove 113 and the through hole 131, and is clamped between the side wall of the pressing part 151 and the bottom wall of the first groove 113, thereby realizing the connection and locking between the first connecting component 11 and the second connecting component 13, and the quick-release connection structure 10 is in a connected state.

[0041] Disassembly: For the quick-release connection structure 10 in the connected state, press the pressing piece 151, and the pressing piece 151 moves toward the direction of the first connection component 11. When the second groove 1511 reaches the position of the through hole 131, the second groove 1511, the through hole 131 and the first groove 113 form a channel, and the movable piece 155 moves toward the second groove 1511 to the position between the second groove 1511 and the through hole 131. The first connection component 11 and the second connection component 13 can be separated smoothly, and the quick-release connection structure 10 is in a disassembled state.

[0042] It can be understood that when the quick-release connection structure 10 is disassembled, according to the installation direction of the quick-release connection structure 10, when the second groove 1511, the through hole 131 and the first groove 113 form a channel, the movable part 155 can be automatically moved from the first groove 113 to the second groove 1511 under the influence of gravity. It can also be that an external force is applied to pull the second connection component 13 out of the first connection component 11, and the two move relative to each other, so that the first side wall 111 of the first connection component 11 generates a thrust toward the second groove 1511 on the movable part 155, and the movable part 155 moves toward the second groove 1511.

[0043] Compared with the prior art, the quick-release connection structure 10 provided by the utility model is provided with the first connection component 11 having the first hollow structure 110 and the second connection component 13 having the second hollow structure 130, the first connection component 11 is provided with the first groove 113 on the inner wall, the second connection component 13 is provided with a through hole 131 corresponding to the first groove 113, the locking component 15 is provided with the pressing member 151, the elastic member 153 and the movable member 155, the pressing member 151 is limitedly accommodated in the second hollow structure 130, the elastic member 153 abuts against the pressing member 151, and provides pressure from the first connection component 11 toward the second connection component 13 to the pressing member 151, and the second groove 1511 is provided on the surface of the pressing member 151 facing the through hole 131. Inserting the second connecting component 13 into the first connecting component 11 can push the movable part 155 from the second groove 1511 to the first groove 113 to achieve locking; pressing the pressing part 151, the pressing part 151 moves relative to the second connecting component 13, and the movable part 155 moves from the first groove 113 to the second groove 1511 to achieve disassembly. The connection and disassembly are convenient, can be used frequently, and are not easily damaged.
