Abstract
The invention relates to a self locking type roller shutter door lock device. A gear sheet, an opening sheet, a rack type lock rod, a safety mechanism and a pawl mechanism are arranged in a lock case, and a lock rod spring is arranged on the rack lock rod. The self locking type roller shutter door lock device is characterized in that a shaft hole of the gear sheet is in a round shape, the side surface of the gear sheet is provided with two transmission salient points, the opening sheet and a lock core are in synchronous rotation, the outer periphery of the opening sheet is provided with a flange matched with the safety mechanism, the side surface of the opening sheet is provided with two arc-shaped grooves, and the transmission salient points arranged on the gear sheet slide in the arc-shaped grooves of the opening sheet. The device has the advantages that during the door closing, only a pawl handle is pulled by hand, the lock rod is automatically popped out, the automatic safety is realized, and convenience in use is realized.
Description
Affiliated technical field
The present invention relates to a kind of Self-locking shutter lock device.
Background technology
Key was exerted all one's strength evenly when existing gear, rack-and-pinion rolling gate door lock were opened, and locking bar moves steadily, but can not automatically lock when closing, and needed key to insert the keyhole rotational lock core and just can lock, the use inconvenience.
Summary of the invention
For overcome existing gear, the problem that can not automatically lock when the rack-and-pinion rolling gate door lock is closed, the invention provides do not need when a kind of rolling-gate is closed key just can self-locking gear, rack-and-pinion rolling gate door lock device.
The technical solution adopted for the present invention to solve the technical problems is: existing gear, rack-and-pinion rolling gate door lock are done following the improvement: load onto self-locking spring on the rack-and-pinion locking bar, there is respectively insurance step and a ratchet locking bar inside edge; Increase by a breakdown sheet in lock core shaft, breakdown sheet and lock core rotate synchronously, and its periphery has flange, and there is a pair of deep-slotted chip breaker the side; Gear sheet axis hole be circular and with lock core movingly, there are two transmission salient points that can slide at breakdown sheet deep-slotted chip breaker the one side; The insurance institution that is made of v shape safety plate, relief spring, bearing pin is arranged in breakdown sheet one side body; There is the detent mechanism that is made of ratchet fork, ratchet spring, pin, ratchet handle the locking bar below.Its operating principle is: when rolling-gate is drop-down when putting in place as long as stir the ratchet handle of this device with hand, locking bar namely outwards ejects under the lock rod spring effect, v shape safety plate its outer end under the relief spring effect props up locking bar insurance step, and locking bar can not inwardly be promoted; When using key rotation lock core, it is inner that breakdown sheet peripheral outer lips is stirred v shape safety plate, after making the safety plate outer end throw off locking bar insurance step, breakdown sheet deep-slotted chip breaker end wall is just against gear sheet transmission salient point, the rotation of gear sheet, locking bar are inside contracted, locking bar inside contracts the rear ratchet fork that puts in place and namely blocks the locking bar ratchet, locking bar can outwards not rebounded and props up guide rail, guarantees that rolling-gate easily opens.
The invention has the beneficial effects as follows, need only stir ratchet handle with hand at closing time, locking bar is automatic spring, voluntary insurance, uses more convenient; Exert all one's strength during unlatching evenly, stable drive.
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is the profile construction schematic diagram of Self-locking shutter lock device locking state of the present invention.
Accompanying drawing 2 is profile construction schematic diagrames of Self-locking shutter lock device opening of the present invention.
Accompanying drawing 3 is Self-locking shutter lock device breakdown sheet elevations of the present invention.
Accompanying drawing 4 is Self-locking shutter lock device gear sheet elevations of the present invention.
In the accompanying drawing: (1) lock housing, (2) lock core assembly, (3) breakdown sheet, (31) breakdown sheet deep-slotted chip breaker, (32) breakdown sheet flange, (5) v shape safety plate, (51) relief spring, (52) bearing pin, (6) gear sheet, (61) gear sheet transmission salient point, (7) rack-and-pinion locking bar, (72) insurance step, (73) locking bar ratchet, (9) lock rod spring, (10) ratchet fork, (11) ratchet spring, (12) pin, (13) ratchet handle.
Gear sheet (6) axis hole is circular, with lock core (2) movingly, the one side has two transmission salient points (61) to slide in breakdown sheet deep-slotted chip breaker (31); Breakdown sheet (3) rotates synchronously with lock core (2), and its periphery has flange (32), can stir v shape safety plate (5) during unlatching, the deep-slotted chip breaker (31) that the side has twice to cooperate with gear sheet transmission salient point (61); There is an insurance step (72) rack-and-pinion locking bar (7) inside edge, can be against the outer end of v shape safety plate (5) after locking, prevent locking bar (7) by the people for pushing; One ratchet (73) is arranged on the locking bar (7), can block ratchet fork (10) after locking bar (7) inside contracts, prevent that the outside bounce-back of locking bar (7) from propping up the rolling-gate guide rail.This device is being closed locking state, see accompanying drawing 1, when key rotation lock core (2), breakdown sheet peripheral outer lips (32) is stirred v shape safety plate (5), make the safety plate outer end throw off locking bar step (72), then the end wall of breakdown sheet deep-slotted chip breaker (31) is against gear sheet transmission salient point (61), gear sheet (6) is rotated, locking bar (7) inside contracts, rolling-gate is opened, ratchet fork (10) blocks locking bar ratchet (73), locking bar can outwards not ejected prop up the rolling-gate guide rail, guarantee that rolling-gate can easily open, see accompanying drawing 2.At closing time, as long as stir ratchet handle (13), ratchet fork (10) is namely thrown off with locking bar ratchet (73), locking bar (7) is automatic spring under spring (9) effect, an end of v shape safety plate (5) props up locking bar step (72) simultaneously, locking bar (7) is not pushed away by in improper, namely lock, insure.
Claims (3)
