Abstract

The utility model discloses an automatic lock for the roller shutter door comprising a lock on a roller shutter and a matching key. The lock comprises a casing, lock tongues which are arranged in the casing, have a rack structure, and can be telescopic movably toward the left and the right, and a lock tongue driving mechanism which is used to drive the lock tongues to complete the telescopic action through the key plugged in a lock core. The automatic lock for the roller shutter door is characterized in that the utility model also comprises a lock tongue locking and unlocking control mechanism which is used to control the positions of the lock tongues and make the roller shutter lie in locking or unlocking state, a lock tongue position-limit mechanism under the locking state, and an automatic locking mechanism. The advantage of the automatic lock for the roller shutter door is that in the lock, the tail parts of the left and right lock tongues are formed into racks which are matched with gears clamped in the middle of the racks, and thus, the lock core can be rotated flexibly and easily under the action of the key; the lock tongues are driven to complete the telescopic motion toward the left and the right. Because of the automatic locking mechanism, when a drive sheet on the dialing head of the roller shutter pulled downwards is contacted with the earth surface, the clamping heads of the lock tongues are dialed by the dialing head in the automatic locking mechanism and separated from a lock tongue clamping groove. Then, a spring mechanism for controlling the motion of the lock tongues pushes automatically the lock tongues to complete locking the roller shutter, and furthermore, the process of locking without needing the key is convenient.

Description

A kind of rolling door automatic locking

Technical field

The utility model relates to a kind of automatic locking that uses on the rolling door in shop, factory, warehouse, garage.

Background technology

At present, shop, factory, warehouse, the widely used rolling screen door lock in Trucks storehouse, owing to do not have automatic mechanism for locking up in the lockset, each open and close rolling door all must be inserted lock core by a key, just can lock or unblank by rotary manipulation, cause the operation of open and close rolling door not only to bother but also bothersome.

Summary of the invention

Goal of the invention of the present utility model is: for the user provides a kind of simple in structure, easy for installation, and the open and close easy and flexible, control is effectively, and is safe in utilization, drop-down self-locking a kind of rolling door automatic locking.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

A kind of rolling door automatic locking, form by being installed in lockset on the roller shutter and supporting key, wherein lockset includes: housing, be contained in and have the dead bolt that rack structure can left and right telescopic moving switch roller shutter in the housing, be inserted in the dead bolt driving mechanism of the key actuated dead bolt telescopic moving in the lock core by dress, it is characterized in that: include also that the control latch bolt position is in roller shutter to lock or the dead bolt switching control mechanism of the state of unblanking out, tongue lock position-limit mechanism under locking state, and automatic mechanism for locking up.

Additional technical feature is:

A, dead bolt driving mechanism are fixed on top cam, suit on the lock core and are fixed on and are positioned at below the cam of top the gear that cooperates with rack structure on the dead bolt on the lock core and form by being positioned at lock core, suit on the housing central horizontal axis position.

B, control latch bolt position are in roller shutter to lock or the dead bolt switching control mechanism of unlocking condition, comprise: two ends are separately fixed at the spring fixator of lower edge on the housing, one end horizontal vertical is fixed on this spring support, the other end is fixed on the fulcrum bar of the spring on the dead bolt batten, be sleeved on the spring on this fulcrum bar of the spring, be arranged on the dead bolt draw-in groove on this dead bolt batten lower edge, be positioned at the below of dead bolt batten and be fixed on the housing inner plate surface, can cooperate the location dead bolt to be in the dead bolt dop of unlocking condition with the dead bolt draw-in groove by fixed rotating shaft.

C, tongue lock position-limit mechanism under locking state, include: be contained in cam left side, top and be positioned at above the gear, the lower end is fixed on the housing inner plate surface by fixed rotating shaft, the push rod that the upper end connects with girt by rotating shaft, the right section of girt is passed the fulcrum bar of the spring that spring support forms arm-tie, the right part of this pull bar i.e. termination of this fulcrum bar of the spring connects firmly the arm-tie that has the chute dop on the plate face, be fixed on the shell holder by fixed rotating shaft, on the body face, have cover and insert the chute of this chute dop, and cooperate the liftable movable clamp of right-hand member, and be contained on the dead bolt batten and cooperate the spacing dop that stops dead bolt displacement under the lock-out state with portable plate with chute dop on the arm-tie.

D, automatic mechanism for locking up, include: be fixed on the housing right-hand member, be positioned at the fixed head above the dead bolt batten, have chute on the plate face, by adorning the fixed head chute post and the shifting block rotating shaft that are inserted in each chute respectively it is sleeved on the fixed head, tongue stretches out the shifting block driving chip of housing lower edge, be sleeved on the horizontal shifting block on shifting block rotating shaft and the chute post, be equipped with shifting block draw-in groove on the dead bolt dop with this shifting block, and the top is fixed on upper edge in the housing, the lower end is fixed on the shifting block driving chip, shaft is set with driving spring can drive the spring controling mechanism that the shifting block driving chip moves down.

Advantage of the present utility model is: because the afterbody of left and right dead bolt forms tooth bar in this lockset, cooperates with gear in the middle of being sandwiched in, can easy and flexible ground rotational lock core under the effect of key, and the left and right sides telescopic moving of driving dead bolt; Owing to be provided with by the dead bolt dop, be mated the dead bolt switching control mechanism that dead bolt draw-in groove on right dead bolt batten and the spring mechanism that moves of control dead bolt are formed, can realize unblanking effectively to be controlled by the dead bolt dop, the movable clamp of locking in the limited mechanism is effectively controlled, and makes this lockset than on the market the more effective safety and reliability of other lockset control; Because this lockset has automatic mechanism for locking up, when drop-down roller shutter when its shifting block driving chip touches ground, shifting block in the mechanism is stirred the dead bolt dop breaks away from itself and dead bolt draw-in groove, the spring mechanism that the control dead bolt moves promotes dead bolt automatically locks roller shutter, and it is convenient to use key both to save trouble.
