Description

The core-inset type safe-guard door lock

Technical field: the utility model relates to a kind of improved core-inset type safe-guard door lock, belongs to five metals lockset industry.

Background technology: market sale now and the core-inset type safe-guard door lock kind of using are a lot, and are divided into L.H.flapped door formula and R.H.flapped door formula, thereby use and must select in sale and user.A L.H.flapped door formula lock pin lock can not be installed in the R.H.flapped door; Equally, R.H.flapped door formula lock pin lock also can not be installed on the L.H.flapped door.Here, the orientation of dead bolt is very important, it must with the opening of door to matching.Like this, bring certain difficulty to use.Have not lock to have two simultaneously, and exchange easily towards function at a lock pin? the purpose of this utility model that Here it is, exploitation has the core-inset type door lock of left and right two-way function, and the structure of core-inset type door lock inside is done new improvement.

The utility model content: the purpose of this utility model provides a kind of core-inset type safe-guard door lock, it is tiltedly increasing Inclined bolt direction changing mechanism on the tongue, can be in the very short time (a few minutes) direction of oblique tongue is changed, to adapt to the needs of L.H.flapped door or R.H.flapped door; And at located lateral plate of square tongue spare top increase, make lock body can bear bigger pressure, thereby overcome some weakness of lock pin lock, become more practical, and theftproof performance is good.For achieving the above object, the utility model is design like this: make oblique tongue do left and right 180 ° rotation at inclined tongue hole, must give the space of its such rotating conditions and rotation.Therefore, the inventor starts with from these two aspects: at first connect oblique tongue rotating shaft in oblique tongue rear end, tiltedly the tongue rotating shaft is installed on the oblique tongue junction plate, tiltedly the tongue junction plate can before and after the distance of an oblique tongue of translation, guarantee that oblique tonguing goes into frame hole and deviate from frame hole (close and open).Make oblique tongue leave inclined tongue hole on the side panel of lock body, go to the outer space of lock body and come, inventor's straight shape groove above lock body has vertically been installed the Inclined bolt direction changing plate of a band spring, and the Inclined bolt direction changing plate can done forward and backward moving in straight shape groove.After the Inclined bolt direction changing plate was upwards passed, under the effect that connects spring, tiltedly the tongue junction plate was pushed ahead, and oblique tongue is released inclined tongue hole, made oblique tongue freely, with finger oblique tongue was exchanged direction, promptly rotated 180 to the left or to the right.And then an oblique tongue is filled in the inclined tongue hole, it is accurately put in place, at last the Inclined bolt direction changing plate is spurred downwards, make it get back to original position, become the scotch that stops oblique tongue junction plate, stop oblique tongue junction plate " to be exceeded the bounds "---march forward again, Inclined bolt direction changing has just been finished like this, very flexibly, conveniently.In order to make lock pin locking-type door lock can bear bigger pressure, the inventor has been installed a location-plate additional on square hyoplastron, " Jiong " shape groove is arranged at location-plate top, " Jiong " shape groove upper end connects return spring, front end connects vertical buckle, and square hyoplastron is inserted in " Jiong " shape groove and is being fitted and connected mutually with location-plate from an end; The location-plate left end has elliptical aperture on the plane, and elliptical aperture is to be connected on the following fixed leg of lock body bottom, and there is dialling at the end of circular arc the location-plate lower end, and right-hand member has rectangular lift span.Like this, stir in the external force of key, location-plate can be done upper and lower moving, can the outside propelling of the side's of assuranceing hyoplastron and square tongue one-level one-level ground, thus make the door lock locking.When square hyoplastron one-level one-level outwards advances, the buckle on the location-plate be jam in the shape groove of square hyoplastron top " U ", " U " shape groove two ends are sturdy, increase the pressure that bears of lock body to cooperate location-plate." Jiong " shape groove of location-plate bottom promptly is by the push structure that hairpin drives of dialling on the lock core, and key rotation half cycle is dialled hairpin and stirred " Jiong " shape groove, distance of the outside translation of square tongue; After key rotates full week, to dial hairpin second " Jiong " shape groove stirred, square tongue stretches out outside the lock body fully, and will lock locking.When the key backward rotation, dial hairpin and again " Jiong " shape groove is inwardly dialled back, thereby will lock unlatching.The utility model has the advantages that significantly: (one) is reasonable in design, simple in structure, and tiltedly tongue can commutate easily, has made things convenient for the user; (2) increase location-plate, make lock body can bear bigger pressure, improved the performance of whole lock body.
