Pull rod lifting self-locking structure of lifting sliding door
The pull rod lifting self-locking structure comprises a lock body with a transmission mechanism, a handle, a pull rod and a fixing plate, the transmission mechanism comprises a cam and a transmission plate which rotate through the handle, the transmission plate is provided with a hook part and a connecting part hinged to the cam, and a hook hole is formed in the pull rod; when the cam is located at the first position, the transmission plate and the pull rod are hooked in the hook hole through the hook part to be directly connected, so that the transmission plate and the pull rod cannot rotate relatively, and at the moment, the lever handle drives the cam to rotate between the first position and the second position in a reciprocating mode so as to drive the pull rod to slide up and down; a self-locking structure is formed among the pull rod, the transmission plate and the cam, so that the transmission plate moves to the highest position and is supported and fixed by the pull rod, and the sliding door can be maintained in a lifting state without manually holding the handle.
本发明公开了一种提升推拉门的拉杆提升自锁结构，包括具有传动机构的锁体、执手、拉杆与固定板，传动机构包括通过执手转动的凸轮和传动板，传动板具有挂钩部和与凸轮铰接的连接部，拉杆上开设有钩孔，传动板与拉杆通过挂钩部钩接在钩孔内直接连接，使传动板与拉杆之间无法相对转动，此时，通过执手驱动凸轮在第一位置和第二位置之间往复转动进而带动所述拉杆上下滑动，当所述凸轮位于第二位置时，拉杆、传动板和凸轮之间形成自锁结构，使所述传动板移动至最高处被所述拉杆支撑固定，无需手动握持执手即可让推拉门维持在提升状态。
