Its internal construction of pull gate theftproof lock is the same substantially with the railing door, and different is will always insure tapered end, latch system is installed in the corresponding box, and the connected mode between its structure and each part is identical.Front end at last lock shaft has a groove (28).

Iron railing door of the present utility model and pull gate theftproof lock, it is simple in structure, and is easy to operate.Adopt two lock shafts, by recessing on lock shaft, utilize switch that the sliding bolt of eccentric wheel control locking bolt realizes locking, safe and reliable, theftproof performance good

Embodiment:

The utility model all adopts metal to manufacture, and the structure of its each parts and installation site are as previously mentioned.Its course of work is as follows: when using key (19) to anticlockwise, because the pin (24) of lock core/(18) and eccentric wheel (22) connects together, eccentric wheel rotates with lock core.Under eccentric effect, locking bolt slide block (11) moves up along slide block alignment pin (12) by slide block slot (13).When moving to the top, lock shaft groove (6) is left on locking bolt slide block top (5), and at this moment, under the effect of spring (8), lock shaft junction plate (7) is finished the process of unblanking in lock shaft (1) setback lock housing (15).Otherwise, will lock tail push rod (9) with hand and push in the lock housing, rotate key to the right, the locking bolt slide block moves down under eccentric effect.When moving to lowest part, the locking bolt upper end of slide block embeds in the lock shaft groove (6) fully, blocks lock shaft and can not return, and finishes the process of closing the door.
