Abstract
A silence mortise door lock comprises a fixing plate and an upper covering plate. A baffle with a bolt hole is installed on the side edge of the fixing plate, and an inclined bolt limiting frame, an inclined bolt baffle, a lock rudder, an inclined bolt, a square bolt and an earth rod are installed inside the fixing plate, wherein the inclined bolt is linked with the lock rudder. A sliding lever which can move on the inclined bolt limiting frame and the inclined bolt baffle in an inserting and sliding mode is placed at the tail end of the inclined bolt, and a push-forward spring is installed on a sliding lever between the inclined bolt and the inclined bolt baffle so as to enable the inclined bolt to keep a popping state from beginning to end. The silence mortise door lock is characterized in that an upper limiting sheet and a lower limiting sheet are placed at the tail end of each sliding lever, a stirring rod fixed on the lock rudder is placed between two limiting rods, and a buffering hydraulic cylinder which can slow down the rotation of the lock rudder is installed on the lock rudder. The silence mortise door lock has the advantages that due to the fact that the buffering hydraulic cylinder is installed on the lock rudder to slow down the rotation of the lock rudder, the occurrence that impact noise is produced by fast reset of a door-opening handle and the inclined bolt can be avoided; the noise is not produced, abrasion is relieved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of lock pin lock, specifically is a kind of quiet lock pin lock that sends noise can prevent from opening the door the handle resilience time.
Background technology
Lockset is one of important accessory of security door, and the quality of lockset performance is directly connected to safety and the functional performance of security door.At present, the security door lockset that uses on the market is of a great variety, characteristic is different, model is also ever-changing, its basic structure is basic identical, generally all include lock body, lock core, dead bolt, lock core is the main means that the dead bolt on the control lock body stretches out (locking) and withdrawal (unblanking), automatically lockset is not then because need manual operation when locking, make it just initiatively locking at closing time, reduced the troublesome operation when locking, extremely easy to use, thereby be subjected to consumers in general's welcome after putting on market deeply always.But also there is its weak point in such lockset: the one, and the product structure complexity, fault is many, application life is short.The 2nd, when rotate handle unblank after and loose one's grip at closing time, the partial component of door lock, reset fast under the effect of back-moving spring as handle, oblique dead bolt etc., at this moment can send bigger impact sound, influence other people work and life within doors, bump causes its quick abrasion fast simultaneously, has had a strong impact on class and the application life of lockset.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.A kind of quiet lock pin lock, it comprises fixed head 1 and upper cover plate, fixed head 1 side is equipped with the baffle plate 2 in house with lock hole 21, be equipped with in the fixed head 1 oblique dead bolt position-limited rack 31, tiltedly dead bolt baffle plate 32, lock rudder 4 and with oblique dead bolt 3, Square lock bolt 5 and the universe rod 6 of its interlock;
Described oblique dead bolt 3 tail ends are provided with sliding thick stick 33 can be at tiltedly dead bolt position-limited rack 31 and the tiltedly interspersed sliding motion of dead bolt baffle plate 32 dos, pushing away spring 7 before being equipped with on the sliding thick stick that oblique dead bolt 3 and oblique dead bolt baffle plate are 32 makes oblique dead bolt 3 remain the ejection state, it is characterized in that: described sliding thick stick 33 tail ends are provided with upper limit bit slice 331 and lower limit bit slice 332, the poke rod 8 that is fixed on the lock rudder 4 places between two gag lever posts, and the buffering hydraulic cylinder 9 that slows down its speed of gyration also is installed on the described lock rudder 4;
12 of described square bar 11 and front and back two panels are equipped with reduction torsion spring 14 and banking stop 15, and banking stop 15 is provided with spacing breach card 16 and puts on the limited post 17 that is positioned on the panel.
Described buffering hydraulic cylinder 9 is arranged on the below of lock rudder 4, and the piston rod 91 of buffering hydraulic cylinder 9 is movably hinged with the stroke sheet 41 that is installed on the lock rudder 4, and cylinder body 92 parts and the fixed head 1 of buffering hydraulic cylinder 9 are movably hinged.
Described buffering hydraulic cylinder 9 is arranged on the top of lock rudder 4, and the piston rod 91 of buffering hydraulic cylinder is movably hinged with the stroke sheet 41 that is installed on the lock rudder 4, and cylinder body 92 parts of buffering hydraulic cylinder 9 are movably hinged by fixed cover 93 and fixed head 1.
The cylinder body tail end of described buffering hydraulic cylinder 9 is provided with the hinge hole 95 that rotating shaft 94 is installed.
Described stroke sheet 41 minutes two symmetries up and down is installed on the lock rudder 4, and described piston rod 91 is installed between the engaging lug 42 on the two stroke sheets, and described stroke sheet is provided with 43 holdings of anti-rotation hole on lock rudder 4.
Operating principle: rotate the handle that opens the door when the user unblanks, handle drives the lock rudder by square bar and rotates, the sliding thick stick 33 of poke rod 8 pulling downwards on the lock rudder drags oblique dead bolt 3 in lock, thereby and push away spring 7 before the compression and realize unblanking, the user unclamps handle, the lock house resets under the effect that preceding pushes away spring, and handle resets under the effect of reduction torsion spring 14.Therefore, conventional art is when handle revolution or automatic spring lock house resilience, and the quick bump of stopping means on lock house and the handle causes bigger work noise and wearing and tearing easily, influences its result of use and application life.And in the utility model, increased buffering hydraulic cylinder at the lock rudder, this hydraulic cylinder is movably articulated between fixed head and the stroke sheet 41 of lock on the rudder, when handle is unblanked or automatically spring lock is given up when compressed, along with toggling it to buffering hydraulic cylinder, the rotation of locking rudder treats buffer status, hydraulic cylinder plays damping action when lock house or handle resilience, limit its velocity of rotation, thereby lower the rebound velocity of lock house and handle, avoid conventional art because of impact noise and component wear that handle, the resilience of lock house high speed cause, prolong its application life.
What wherein need to remark additionally is: because the influence of part distributing position in being subjected to locking, buffering hydraulic cylinder can be installed in lock rudder below in the utility model, adopts the overhanging damp type oil cylinder of piston rod.Also buffering hydraulic cylinder can be installed to lock rudder top, adopt piston rod retraction damp type oil cylinder, concrete application can be used according to reality and change, so do not limit herein.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of claims of the invention.
