Also include lock ring, the lock ring has opening, and its lower end is flexibly connected with the lock frame, and upper end is flexibly connected with upper connecting rod;It is described
Lock ring bottom is that knee top is straight-bar;The knee is connected with the straight-bar axis hole;The lock ring by with it is described lock frame, on
Pull bar is combined into a linkage.
Further, the lock ring knee body of rod is in a variety of gradients.
Further, in addition to the first bearing pin, the second bearing pin, the 3rd bearing pin, the lock ring lower end are sold by described first
Axle is rotatably connected with the lock frame;The knee and straight-bar of the lock ring are rotatably connected by second bearing pin;The lock
Ring upper end is rotatably connected by the 3rd bearing pin with the upper connecting rod.
Further, first bearing pin, the second bearing pin, the 3rd bearing pin be arranged in parallel.
Further, in addition to some guiding slide plates, the guiding slide plate is incorporated on the lock frame, and is distributed in described
Upper connecting rod, lower pull bar both sides.
Further, the extended lock frame 20-35mm of the lock ring.
Further, the lock ring stretches out in two stages, and its first stage stretches out 20mm, and second stage stretches out 35mm.
Further, the lock ring is hard metal material.
The beneficial effect that the present invention is compared with the prior art includes:Knee is designed to down narrow wide structure, can effectively save
The about space-consuming of knee;Knee, straight-bar, lock frame, upper connecting rod are combined into one group of linkage by way of axis hole connection, if
Count ingenious, flexibility height;Lock ring according to service condition, by its distance that controller stretches out on request, can improve the safety of door lock
Performance.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is present invention assembling schematic cross-section.
Embodiment
With reference to embodiment and compare accompanying drawing the present invention is described in further detail.It is emphasized that
