Abstract
The utility model relates to a lock for rolling doors, which is composed of a lock body, a lock core, a link gear, a lock tongue, and a rolling door. The utility model is arranged at the position which is 0.8 to 1.5 meters away from the bottom of the rolling door. The utility model overcomes the defect that the surface of the lock tongue is directly driven by a key of a former lock for rolling doors. Because the lock tongue is driven by a key link gear, the utility model has the advantages of safety, reliability and convenient operation, and is a new generation of product.
Description
The utility model relates to a kind of lockset, particularly a kind of rolling screen door lock.
Rolling door is the door of open-width greatly of a kind of safe ready of more use on the present commercial shop front, but because time of occurrence is not long, so join use lockset all be to drive opening mechanism by key turns merely, intensity is limited because key is small and exquisite, be easy to cause disconnected spoon phenomenon to take place, lockset is loaded on the bottom in addition, causes the switch inconvenience of console mode rolling door.
In order to overcome above-mentioned shortcoming, the purpose of this utility model is that the locking mechanism of inventing a kind of key and interlock does not directly drive spring bolt mechanism, and the lock body installation site is made things convenient for again on the position of open operation.
The utility model is finished by following technical scheme.
A kind of rolling screen door lock, it is by lock body (1), lock core (2), link gear, dead bolt (3) and rolling door constitute, it is characterized in that, lock body is fixedly mounted on rolling door apart from the bottom between 0.8 meter to 1.5 meters, and link gear is made up of button link gear and locking opening mechanism, and the button link gear is by the button (4) that is arranged on above the lock body (1), button slide plate (5) with button (4) is fixedly connected is equipped with the return spring (6) that connects with lock body (1) on the button slide plate (5).With button slide plate (5) bilateral symmetry rotate respectively connect a left side, right triangle connecting rod (7), a left and right sides delta link (7) and a left side, right connecting rod (8) rotates and connects, left and right sides connecting rod (8) respectively with a left side, right strip formula dead bolt (3) rotates to connect and constitutes, the locking opening mechanism is by the gear (9) that is fixedly set in lock core (2) pivotable parts, rotate the gear (10) and gear (9) engagement that connects with lock body, be symmetrically arranged with two tooth posts (11) on gear (10) horizontal diameter, the tooth post is set with on one, once two tooth bars (12) tooth pitch of constituting tooth bars (12) equals the distance between the bidentate post (11), also is provided with the handle that opens the door (13) in the lower backside of button link gear.
The operating principle of the locking link gear that is driven by lock core is, lock core (2) driven gear (9) rotates, gear (9) driven gear (10) rotates, two tooth posts (11) on gear (10) are stirred (12) one of tooth bars respectively left, and one to the right motion, and the front end of tooth bar is withstood on the step of strip formula dead bolt (3) afterbody, dead bolt (3) can not be withdrawn backward, otherwise after tooth bar contracted together, dead bolt (3) freely stretched under button 4 drives, and reaches the purpose of opening locking.
The operating principle of button link gear is, it is descending that button (4) drives button sliding panel (5), button slide plate (5) drives left and right sides triangular coupling rod (7) makes triangular coupling rod inwardly move with the end that left and right sides connecting rod (8) connects, reach the action of unlatching thereby drivening rod (8), strip dead bolt (3) inwardly move, otherwise the button link gear makes strip dead bolt (3) be in extended position under the effect of return spring (6).The pushing hands of opening the door of lower backside in like manner also can drive simultaneously strip dead bolt (3) withdrawal.
Since the lock body position be mounted in rolling door apart from the bottom 0.8 meter to 1.5 meters, so the people is on the best operated position when making the switch rolling door, reached goal of the invention.
Advantage of the present utility model is, makes the core of rolling screen door lock not drive long dead bolt and make it safer, and is reliable and be convenient to operation.
Accompanying drawing 1 is the utility model scheme of installation
Accompanying drawing 2 is the utility model button link gear structural representation.
Accompanying drawing 3 is the utility model locking opening mechanism structural representation.
Accompanying drawing 4 is the utility model back side overall structure schematic diagram.
Below by embodiment the utility model is further described.
Lock body is made box and bonnet by iron plate, and lock core adopts traditional lock cylinder, the button slide plate, and triangular coupling rod, connecting rod, the strip dead bolt is all made as the accompanying drawing shape with the iron plate punching press, and turns riveted joint.Gear (9) (10) is iron, splice respectively at (10) last 1/2nd radius places and to be in two tooth posts on the same diameter, tooth bar also is that the iron punching press is made as the accompanying drawing type, carries out suit again, and the back pullout (BPO) handle is installed and is pressed the plastic button of peace in button slide plate upper end.And it is assemblied on the rolling door gets final product.
Above-mentioned lock core also can use other rotation lock core.
