The invention belongs to the technical field of aviation air drop, and discloses a novel parachute mechanical automatic release device, which is characterized in that a shell is mounted on a lock body, and a locking structure and a safety timing structure are fixed on the lock body. The locking structure comprises a lock hook and a separating hook, and the lock hook is installed in the lock body through a pin shaft, can rotate around the pin shaft and is matched with the upper end of the lock body to form a locking or opening state. The separating hook is installed in the lock body through a pin shaft and can rotate around the pin shaft, and the separating hook is matched with the lock hook through rotation and plays a role in limiting the lock hook. A safety timing device is adopted, it is guaranteed that when throwing is started and the device does not reach a stable operation state, a locking structure is kept closed and is not interfered by external factors, and the bearing safety is guaranteed; when the device lands, the cargo load disappears, the spring drives the shell to reset, at the moment, only friction force between the separating hook and the inner wall of the shell needs to be overcome, and it is guaranteed that the lock is unlocked immediately after landing, and the parachute is separated in time.
本发明属于航空空投技术领域,公开了一种新型降落伞机械式自动脱离装置,外壳安装于锁体上,上锁结构和保险计时结构固定于锁体上。上锁结构包括锁钩、脱离钩,锁钩通过销轴安装于锁体内,并能绕销轴旋转,与锁体上端配合形成上锁或开放状态。脱离钩通过销轴安装于所述锁体内,并能绕销轴旋转,脱离钩通过旋转与所述锁钩配合,对锁钩起限位作用。采用保险计时装置,保证投放开始时,当装置未达到稳定运行状态时上锁结构保持闭合,不受外界因素干扰,保证承载安全性;当装置着陆时,货物负载消失,弹簧带动外壳复位,此时只需克服脱离钩和外壳内壁之间的摩擦力即可,保证着陆后即刻开锁,伞物及时分离。
