Description

Rolling gate door lock

Belong to technical field

The utility model rolling gate door lock, be below the track of the door left and right sides, lock in, under auxiliary catch and ground below duplicate combine and fixes.

Background technology

At present, known rolling gate door lock is by the tapered end core, gear, the tooth bar connecting rod, lock housing, constitute, door lock be fixedly mounted on a inside under, when rolling-gate is closed from top to down, tapered end rotates under the effect of key external force and drives the core gear, the tooth bar connecting rod, the tooth bar connecting rod is stretched out to the left and right, drive is movably arranged on the extension bar on the door, combine fixedly rolling-gate with the pod correspondence position on the track, but find that in practice it also has some weak point, particularly limited by the fixing degree of depth of both sides connecting rod, and wide (the striding) of door degree often big (mechanical strength is relatively low) so more easily pried open from the left and right sides.

Summary of the invention

In order to overcome the shortcoming that existing door lock is easily pried open from the left and right sides, the utility model provides a kind of rolling gate door lock, in order to shorten the distance of keyed end, reduce the door leaf flexibility, strengthen its intensity, special in the middle of door lock with below the ground, increase auxiliary catch in about door fixing the time, thus by about original 2 fixedly become at 3 and fix.

The technical scheme that its technical problem that solves the utility model adopts is: by the tapered end core, gear, the tooth bar connecting rod, the interlock auxiliary catch, lock housing, below, ground duplicate constitutes, door lock be fixedly mounted on a inside under, fluting is installed duplicate on the ground below door lock, fix by expandable nail, when door is closed from top to down, the tapered end core is rotation driven gear tooth bar connecting rod under the effect of key external force, the interlock auxiliary catch, the tooth bar connecting rod is stretched out to the left and right, drive is movably arranged on a pod correspondence position on extension bar and the track on the door and combine fixedly about rolling-gate, the interlock hook also stretch simultaneously combine with duplicate below the ground fixed gate under, reach 3 fixing purposes.

The beneficial effects of the utility model are, in the time of about locking and below locking medially, have shortened the keyed end distance, have strengthened the intensity of door.
