Description
Technical field
The utility model relates to a kind of driving mechanism that has the arc-shaped lock bolt in the arc-shaped lock bolt safe-guard door lock.
Background technology
The safe-guard door lock that has arc-shaped lock bolt, the arc-shaped lock bolt body is curved, and locking bolt is articulated on the lock body by pivot, and can make cylinder body around pivoted by transmission mechanism.When realizing the locking of safe-guard door lock, cylinder body is rotated and is turned over successively two set locking bolt Kongzuis of doorframe and inserts in the hole set on the lock panel eventually towards the outside of lock body.And when realizing release, the cylinder body backward rotation also finally is fully retracted in the lock panel.The safe-guard door lock of existing this structure, the arc-shaped lock bolt in it is connected on the lock body by pivot, is fixed with gear on pivot, is provided with the gear piece of end and gears engaged in lock body, and gear piece is to be driven by the shifting block on the lock core driving the arc-shaped lock bolt motion.Because the setting of gear piece, the driver part of some master latches is set in the feasible lock body more again, safe-guard door lock plays the just arc-shaped lock bolt of main locking action, can not set the master latch of straight-bar type on the safe-guard door lock of this structure, compare with the safe-guard door lock that has the straight-bar type master latch, this simple safe-guard door lock that is played main locking action by arc-shaped lock bolt has determined that owing to the setting means of arc-shaped lock bolt in lock body its safety in utilization is relatively poor.
In addition, because locking bolt is to carry out work in the mode of rotating, the transmission mechanism that connects between locking bolt and the lock core is comparatively complicated, existing connection matching relationship between each parts, relative action relationships is arranged again, catching phenomenon easily takes place between them, this can make the unlatching of safe-guard door lock and lock operation not smooth, influenced the normal use of safe-guard door lock, for the reputation of manufacturer is brought adverse influence.
The utility model content
The purpose of this utility model is the safe-guard door lock that has arc-shaped lock bolt at existing, owing to the defective of arc-shaped lock bolt driving mechanism causes the problem of safe-guard door lock theftproof performance difference, and provide a kind of simple in structure, be convenient to driving mechanism for the straight-bar type master latch and provide and the space is set, causes safe-guard door lock arc-shaped lock bolt driving mechanism safe to use.
The purpose of this utility model can realize by following technical proposal: safe-guard door lock arc-shaped lock bolt driving mechanism, comprise the rotating disk and the joining main fork of arc-shaped lock bolt that are articulated in the lock body, rotating disk be used for door lock in sliding bolt link, described rotating disk is the lengthy motion picture shape, its end is pressed on the arc-shaped lock bolt, and the other end links by intermediate transmission mechanism and main fork.
This safe-guard door lock arc-shaped lock bolt driving mechanism also can be done following improvement
The other end of described rotating disk is hook-shaped.
Described main fork and the described intermediate transmission mechanism place of linking are provided with sliding pin, are provided with chute on the lock body of safe-guard door lock, and described sliding pin is inserted in the chute with gap.
Described intermediate transmission mechanism comprises the connecting rod that connects rotating disk and main fork.
Be articulated with secondary fork in lock body, secondary fork is identical with the pivot of rotating disk, and an end and the described connecting rod of secondary fork link.
Described connecting rod medium position place is fixed with attachment pegs, and attachment pegs is plugged in the set slotted hole of described secondary swing link end part with gap.
The thickness of the above slotted hole position of described secondary fork is greater than the thickness of other parts on the secondary fork.
Described secondary fork is arranged between rotating disk and the main fork, and the three stacks together.
Compared with prior art, the beneficial effects of the utility model are:
This arc-shaped lock bolt driving mechanism is in the transferring power process, be to realize by the upper and lower sliding bolt of being located in the lock body, this driving mechanism not with lock core on shifting block directly contact, can not have influence on the setting of straight-bar type master latch driving mechanism in lock body, both can have the straight-bar type master latch on the safe-guard door lock, also have simultaneously a cover or two cover arc-shaped lock bolts, increased the safety in utilization of safe-guard door lock.Rotating disk is the lengthy motion picture shape and is articulated in the lock body, its end is pressed on the arc-shaped lock bolt, safe-guard door lock is when realizing unlatching or lock operation, arc-shaped lock bolt is rotating, and under the drive of sliding bolt, rotating disk also is to rotate, and all is to work in the mode of rotating just because of rotating disk and arc-shaped lock bolt, one end of rotating disk can very stably be pressed on the arc-shaped lock bolt, is convenient to guarantee the stability of arc-shaped lock bolt work.
