Abstract
The utility model relates to a lockset control mechanism, in particular to a gear rack stretching mechanism for a lockset of an antitheft door. A lock cylinder gear is arranged on the exterior of a lock cylinder; the lock cylinder gear is meshed with a rack; a connecting pillar is arranged on the rack; a connecting pillar slide slot is arranged on a pulling plate; the connecting pillar passes through the connecting pillar slide slot; the bottom end of a spring bolt stretching limiting sheet is connected with the pulling plate through a rotating shaft; a stirring lug is arranged on the bottom end of the spring bolt stretching limiting sheet; the connecting pillar is arranged above the stirring lug; a reset spring is arranged on the spring bolt stretching limiting sheet; a spacing sheet is arranged at the top end of the spring bolt stretching limiting sheet. The gear rack stretching mechanism for the lockset of the antitheft door has the advantages that the operation noise of the mechanism is reduced through the structure of the lock cylinder gear and the rack, and the unlocking vaulting phenomenon of the lock of the antitheft door is avoided.
Description
Technical field
This patent relates to lockset controlling organization, is specially a kind of antitheft door lockset rack-and-pinion telescoping mechanism.
Background technology
What existing antitheft door lockset adopted is that cam is stirred structure, be exactly that lock core rotates, by projection, stir dead bolt stretching device and realize unlock operation, its defect is that the main scope of middle key turns of unblanking does not stress, and at projection, stirs the time, and lockset need to twist energetically, sensuously lockset has the state of unexpected redirect, and noise is very large, service life of equipment is short, and fault is many.
Summary of the invention
This patent, for above technical problem, provides a kind of antitheft door lockset rack-and-pinion telescoping mechanism.
Antitheft door lockset rack-and-pinion telescoping mechanism, by tooth bar, banking stop, joint pin, arm-tie, dead bolt stretches out margining tablet, lock core gear, joint pin chute, rotating shaft, stirring projection forms, lock core gear is arranged on outside lock core, lock core gear and tooth bar are meshing, joint pin is set on tooth bar, joint pin chute is set on arm-tie, joint pin is through joint pin chute, the bottom that dead bolt stretches out margining tablet is connected on arm-tie by rotating shaft, dead bolt stretches out the bottom setting of margining tablet and stirs projection, joint pin is arranged on stirs projection top, dead bolt stretches out back-moving spring is set on margining tablet, the top that dead bolt stretches out margining tablet arranges banking stop.
Lock core rotates after key enters, the mode of rotating with lock core gear drives rack linear motion, unblank in process, the motion in early stage of tooth bar is that combination banking stop, joint pin move within the scope of joint pin chute, joint pin compressing dead bolt stretches out the projection of stirring that the bottom of margining tablet arranges, dead bolt stretches out margining tablet and rotates along rotating shaft, and the banking stop that the top that this rotation makes dead bolt stretch out margining tablet arranges departs from spacer, thereby realizes all operations were of dead bolt retraction.
The advantage of this patent has been embodied in by the Structure Decreasing of lock core gear, tooth bar the operation noise of mechanism, and has solved the phenomenon of the kick of unblanking of safe-guard door lock.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent.
Fig. 2 is that this patent lock core gear pulls open the structural behavior figure while protecting banking stop.
Fig. 3 is the structural representation of joint pin chute and joint pin.
Wherein, 1---tooth bar, 2---joint pin, 3---dead bolt stretches out margining tablet, 4---arm-tie, 5---joint pin chute, 6---rotating shaft, 7------banking stop, 9---lock core gear of stirring projection, 8.
The specific embodiment
Below in conjunction with the specific embodiment, this patent is described further.
Antitheft door lockset rack-and-pinion telescoping mechanism, by tooth bar 1, banking stop 8, joint pin 2, arm-tie 4, dead bolt stretches out margining tablet 3, lock core gear 9, joint pin chute 5, rotating shaft 6, stirring projection 7 forms, lock core gear 9 is arranged on outside lock core, lock core gear 9 is meshing with tooth bar 1, joint pin 2 is set on tooth bar 1, joint pin chute 5 is set on arm-tie 4, joint pin 2 is through joint pin chute 5, the bottom that dead bolt stretches out margining tablet 3 is connected on arm-tie 4 by rotating shaft 6, dead bolt stretches out the bottom setting of margining tablet 3 and stirs projection 7, joint pin 2 is arranged on stirs projection 7 tops, dead bolt stretches out on margining tablet 3 back-moving spring is set, the top that dead bolt stretches out margining tablet 3 arranges banking stop 8.Tooth bar and lock core gear are all 8 teeth.
Lock core rotates after key enters, the mode of rotating with lock core gear drives rack linear motion, unblank in process, the motion in early stage of tooth bar is that combination banking stop, joint pin move within the scope of joint pin chute, joint pin compressing dead bolt stretches out the projection of stirring that the bottom of margining tablet arranges, dead bolt stretches out margining tablet and rotates along rotating shaft, and the banking stop that the top that this rotation makes dead bolt stretch out margining tablet arranges departs from spacer, thereby realizes all operations were of dead bolt retraction.
