The invention relates to a locking and releasing device based on a connecting rod type structure, the locking and releasing device comprises a load connecting mechanism, a locking base, a pin puller, a pressing rod, two fasteners, an unlocking spring, a first connecting rod, a second connecting rod and a rotating rod, the upper end of the pressing rod is connected with the load connecting mechanism, and the lower end of the pressing rod is located in the locking base; the middles of the two fasteners are hinged into the locking base, a first connecting rod and a second connecting rod are hinged to the lower ends of the two fasteners respectively, the two ends of the rotating rod are hinged to the first connecting rod and the second connecting rod respectively, the middle of the rotating rod is hinged into the locking base, and the lower end of the unlocking spring is connected with the inner side of the bottom of the locking base. The upper end of the unlocking spring is connected with the lower side of one end of the rotating rod; the upper end of the fastening piece is connected with the pressing rod in a matched and clamped mode. The pin puller can clamp and release the rotating rod; in a locking state, the pin puller is used for clamping the rotating rod, and the unlocking spring is in a stretching state; and in the unlocking state, the pin puller releases the rotating rod, and the unlocking spring restores deformation and drives the rotating rod to rotate.
本发明涉及一种基于连杆式结构的锁紧释放装置,包括载荷连接机构、锁紧底座、拔销器、压紧杆、两个扣紧件、解锁弹簧、第一连杆、第二连杆和转杆,压紧杆上端与载荷连接机构连接,压紧杆下端位于锁紧底座内;两个扣紧件的中部铰接在锁紧底座内,两个扣紧件的下端分别铰接有第一连杆和第二连杆,转杆两端分别与第一连杆和第二连杆铰接,转杆中部铰接在锁紧底座内,解锁弹簧下端与锁紧底座底部内侧连接,解锁弹簧上端与转杆一端下侧连接;扣紧件的上端设有与压紧杆适配卡接;拔销器能够实现对转杆的卡接与释放;锁紧状态时,拔销器对转杆进行卡接,解锁弹簧处于拉伸状态;解锁状态时,拔销器对转杆进行释放,解锁弹簧恢复形变并带动转杆旋转。
