Description
The utility model relates to a kind of door lock, particularly a kind of core-inset type safe-guard door lock with multi-faceted dead bolt.
At present, in the safe-guard door lock field, old-fashioned mortise door lock structure is outmoded, and its tapered end is connected insecure with lock body, and is difficult for installing, and single slow-witted dead bolt is not often born bump and sled risk surreptitiously, and its theftproof performance is relatively poor.
The purpose of this utility model is to provide a kind of safe-guard door lock with multi-faceted dead bolt, has overcome defectives such as the installation inconvenience of old-fashioned core inserted door and theftproof performance difference.
The technical solution of the utility model is as follows: in the safe-guard door lock transmission mechanism that is constituted by tapered end, lock core, lock body, dead bolt, lock housing and handle etc., be equipped with a crank slot balance and with the interactional clamping block of crank slot balance, be equipped with a through hole that can match with handle Fang Xin on this crank slot balance, and also be equipped with one or more than one guiding crank slots, side at the crank slot balance has a protuberance, this clamping block is connected with lock core, and being subjected to the control of lock core and side-to-side movement, the one side has a groove that can match with crank slot balance protuberance.This safe-guard door lock in the horizontal direction and vertical direction all be equipped with dead bolt.Each dead bolt is connected with the crank slot balance by dead bolt pin and guiding crank slot, and the dead bolt pin can slide in the guiding crank slot.Be equipped with spacing steel ball on the clamping block.
Because the utility model is at the multi-faceted dead bolt that is provided with, can make security door locked behind the locking in level, multi-faceted while such as vertical, like this, both reached the requirement that door anti-collision, pick-proof are stolen, simultaneously the firm intensity of door lock itself is increased, for the antitheft public security of society plays a role.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Accompanying drawing is a structural representation of the present utility model.
Ginseng is with accompanying drawing, and present embodiment is equipped with lock housing 1 outside lock body 11; Have three guiding crank slots 12 on the crank slot balance 3, the center of crank slot balance 3 has through hole 13, and its shape just in time matches with handle side's core 2, and crank slot balance 3 is enclosed within on handle side's core 2 by through hole 13, and rotates with the rotation of handle; The dead bolt pin 4 of dead bolt in succession all is housed in the guiding crank slot 12 of crank slot balance 3, and this dead bolt pin 4 can slide in crank slot 12 with the rotation of crank slot balance 3; Present embodiment is provided with the slow-witted dead bolt 5 of 3 folk art terms in the horizontal direction, is provided with secondary dead bolt 6 and following secondary tapered end 6.1 at the vertical direction branch, and security door is lockable simultaneously in upper and lower, three orientation, a left side, reaches purpose crashproof, pick-proof; Spring 7 acts on the slow-witted dead bolt 5 of folk art term, makes it have the function that resets during as windproof dead bolt one grade of indentation; The right side of crank slot balance 3 is made as vertical plane, and in the central authorities on the plane of hanging down one protuberance B is set; Clamping block 8 is connected with lock core, under the control of lock core upper shift fork 10, clamping block 8 can be done the advance and retreat motion of level, and after rotation crank slot balance 3 pushing tow dead bolts were made the locking shape, rotary locking cylinder was moved to the left shift fork 10 pushing tow clamping blocks 8, at this moment, the set groove A of these clamping block 8 left surfaces just in time matches with crank slot balance 3 upper convex portion B, thus fixing crank slot balance 3, and handle can not rotate, therefore dead bolt is fixed, can not be retreated; When need are unblanked, the reverse rotation lock core, clamping block 8 is under shift fork 10 effects, and its groove A leaves the protuberance B of crank slot balance 3, and handle can rotate again again; Therefore the utility model also sets up spacing steel ball 9 in the bottom side of clamping block 8 in order to make safe-guard door lock action more infallible, and after protuberance B and groove A coincide, spacing steel ball 9 embedding limited pits were fixed on the self-locking position clamping block 8.
