The invention relates to the technical field of sliding-plug doors, and discloses a middle dual sliding-plug and locking mechanism of a sliding-plug door. The mechanism comprises a base plate, whereinconnecting plates are fixedly connected to the left end and the right end of the base plate respectively, supports are fixedly connected to the front faces of the opposite sides of the two connectingplates respectively, synchronous wheels are movably connected to the back faces of the supports, synchronous belts are movably connected to the outer surfaces of the synchronous wheels, a fixed shaftis fixedly connected between the back faces of the opposite sides of the two connecting plates, and a first connecting rod is fixedly connected to the bottom of a first sleeve. According to the middle dual sliding-plug and locking mechanism of the sliding-plug door, the first sleeve and a second sleeve are synchronously driven by the synchronous belts to move, so that sliding-plug and locking ofthe sliding-plug door are realized; the purpose of locking a door plate can be achieved through a limiting pin on the second sleeve, and the locking effect is safe and reliable by adopting the sleevewhich is directly locked and rigidly connected with the door plate; and since the limiting pin and a limiting shaft are arranged on the same sleeve, the two functions of sliding-plug and locking can be simultaneously achieved, and mounting is simple.

    本发明涉及塞拉门技术领域,且公开了一种中双塞拉门塞拉锁闭机构,包括基板,所述基板的左右两端均固定连接有连接板,两个所述连接板相对一侧的正面均固定连接有支架,所述支架的背面活动连接有同步轮,所述同步轮的外表面活动连接有同步带,两个所述连接板相对一侧之间的背面固定连接有固定轴,所述第一套筒的底部固定连接有第一连杆。该中双塞拉门塞拉锁闭机构,通过同步带同步带动第一套筒与第二套筒运动,以此实现塞拉门的塞拉和锁闭,由第二套筒上的限位销,可以达到锁闭门板的目的,这种直接锁闭和门板刚性连接的套筒,锁闭效果安全可靠,限位销和限位轴在同一套筒上同时可以实现塞拉门和锁闭两项功能,安装简易。
