Lock body structure for vertically locking door body
The invention discloses a lock body structure for vertically locking a door body, and relates to the field of freezing and refrigerating display cabinets. The device comprises a box body and a movable door, a connecting rod cam is installed in the middle of one side of the movable door, two connecting rods are connected to the two ends of the connecting rod cam through rotating shafts, and a first-stage limiting guide sleeve, a second-stage limiting guide sleeve, a third-stage limiting guide sleeve and a directional guide sleeve are installed on the movable door; the connecting rod cam is installed on the middle door opening part of the movable door, the two ends of the connecting rod cam are connected with the connecting rod through the rotating shafts, when the lock is unlocked, the connecting rod shrinks towards the middle, the two ends of the connecting rod retract into the movable door body, the door can be smoothly opened, and when the door is locked, the lock cylinder is rotated by 90 degrees, and the connecting rod cam stands up; the connecting rod extends towards two ends under the driving of the eccentric wheel, so that the tail end of the connecting rod extends out of the door body and enters a fixing hole formed in the box body fixing plate. The purpose of locking the movable door up and down is achieved.
本发明公开了一种上下锁门体的锁体结构，涉及冷冻冷藏展示柜领域。本发明包括箱体和活动门，所述活动门的一侧中间位置安装有连杆凸轮，所述连杆凸轮的两端通过转轴连接有两个连杆，所述活动门上分别安装有一级限制导套、二级限制导套、三级限制导套和定向导套，所述活动门的上方和下方均固定有固定板，本发明通过在活动门中间开门部分安装连杆凸轮，连杆凸轮两端通过转轴连接连杆，当开锁时，连杆往中间收缩，两端也跟着缩进活动门体，可以顺利开门，锁门时，将锁芯旋转90度，连杆凸轮立起来，偏心轮的带动下，连杆往两端伸，使连杆末端伸出门体，进入箱体固定板上开设的固定孔里面。起到将活动门上下锁住的目的。
