Spinning type locking device for lower side door
The invention discloses a spinning type locking device for a lower side door. The spinning type locking device comprises a pressing buckle fixing device and a rotating handle device. The pressing buckle fixing device is composed of a fixing base, an eye ring bolt and a pressing buckle. The rotary handle device is composed of a handle connecting rod, an L-shaped handle and a backstop. The locking device adopts a spiral pressing structure, has a self-locking function and can ensure that the lower side door cannot be automatically opened after being closed, and an eye ring bolt structure is adopted, so that a pressing buckle is loosened through a handle rotating device when a door is opened, and the pressing buckle can be completely separated from a hinge; a certain distance is reserved between the L-shaped handle and the eye ring bolt, the L-shaped handle serves as a rotating force arm, operation is easy, enough pressing force is achieved after the door is closed, and loosening is not prone to occurring; the eye ring bolt is of a full-thread structure, it is guaranteed that the pressing buckle has enough stroke, size errors caused by deformation can be compensated, and it is guaranteed that all the lower side doors can be completely closed and pressed. The stop structure of the rotary handle device limits rotation of the handle seat, it is guaranteed that the locking device does not act in the working state, and mistaken opening is avoided.
本发明公开了一种下侧门旋压式锁闭装置，包括压扣固定装置和旋转手柄装置；压扣固定装置由固定座、眼环螺栓和压扣构成；旋转手柄装置由手柄联杆、L型手柄和止挡构成。本发明锁闭装置采用螺旋压紧结构，具有自锁功能，可保证下侧门关闭后不能自行打开，采用了眼环螺栓结构，开门时通过手柄旋转装置松开压扣，压扣可完全脱开折页；L型手柄与眼环螺栓之间有一定距离，作为旋转力臂，操作轻松，关门后有足够压紧力，不易松动；眼环螺栓采用全螺纹结构，保证压扣有足够的行程，可补偿因变形造成的尺寸误差，保证所有下侧门均能完全关闭并压紧；旋转手柄装置的止挡结构限制手柄座的转动，保证在工作状态下锁闭装置不动作，避免误打开。
