The invention is suitable for the technical field of aircraft parts, and provides an eccentric pin cabin section connecting form which comprises a front cabin section and a rear cabin section, a connecting mechanism is arranged between the front cabin section and the rear cabin section, and the connecting mechanism comprises a front cabin convex block, a rear cabin concave block, an eccentric pin and a bandage. According to the connecting mechanism, through clamping connection of a front cabin convex block and a rear cabin concave block and cooperation of an eccentric inner cavity and an eccentric pin, the front cabin section and the rear cabin section are clamped and fixed through rotation of the eccentric pin after connection, binding of a binding band to the eccentric pin is matched, and therefore after the front cabin section and the rear cabin section are connected, compared with an existing cabin section connecting mode, the connecting mode is more stable. The connecting structure is small in occupied space in a cabin, small in number of parts, easy to machine, reliable in connection, easy to assemble and convenient to disassemble, and can meet the connecting strength and rigidity requirements of the aircraft.
本发明适用于飞行器零件技术领域,提供了偏心销舱段连接形式,包括前舱段和后舱段,所述前舱段和后舱段之间设有连接机构,所述连接机构包括前舱凸块、后舱凹块、偏心销和绑带,该舱段连接形式,由于前舱段和后舱段之间设有连接机构,连接机构通过前舱凸块和后舱凹块的卡接以及偏心内腔和偏心销的配合,在连接后通过偏心销的旋转来对前舱段和后舱段进行卡紧固定,配合绑带对偏心销的绑定,所以前舱段和后舱段在连接后,相对于已有舱段连接形式,占用舱内空间很少,零件数量少、加工简单,连接可靠、装配简单、拆卸方便,并且能满足飞行器连接强度和刚度要求。
