Abstract

The utility model discloses an improved lock, which comprises a lock body, the two points in the lock body is provided with a racing lock core with same structure. The utility model is characterized in that: end of each rotary sheath of lock core is provided with a shifting block. Compared with the prior lock, for adopting the racing lock core, the utility model improves the performance of preventing technological unlocking and destructively lock picking largely.

Description

A kind of improved tapered end

Technical field

The utility model belongs to mechanical lockset, is specifically related to a kind of improved tapered end that is used for the built-in type mortise door lock.

Background technology

The tapered end of existing built-in type mortise door lock wherein has a kind of twin-lock cored structure, can be from two different directions with key respectively with lock-switch.Two lock cores all are to adopt identical structure, are provided with a shifting block between two lock core ends, and shifting block is realized and the interlock of dead bolt thereby each lock core can drive by an arrangement of clutch.The deficiency of this tapered end is that the lock core that is adopted is not high aspect safety, can not effectively prevent skilled unlocking and destructive picking lock.

Preventing skilled unlocking and destructive picking lock aspect of performance, the lock core that some theftproofs better can dally has appearred at present, this lock core is provided with a turning set between lock core and lock body, be characterized in, can unblank when unblanking with matched key, and when using non-matching key to unblank, can only make lock core relatively rotate cover idle running, this lock core can make external force can't act on lock body and sword iron, thereby has solved powerful unblanking and a destructive difficult problem of unblanking preferably.At present, this class lock core does not also have to find to be applied on the tapered end of built-in type mortise door lock.

Summary of the invention

The purpose of this utility model is at above-mentioned situation, and a kind of improved tapered end that comprises idle-run lock pin is provided.

The utility model purpose is achieved in that improved tapered end comprises lock body, and the two in the lock body is provided with the idle-run lock pin of same structure, and the end of each lock core turning set is fixed with shifting block;

Described idle-run lock pin is made up of active lock core and turning set, initiatively lock core is enclosed within the turning set, in the groove of the hole of active lock core, be provided with shell fragment, the plurality of rows shell fragment is arranged along lock core shaft's line parallel, each row has single shell fragment or is staggered and partly overlapping double shell fragment, single face or the two-sided keyway that all has on each shell fragment, this keyway decides the keyway deviation post of each shell fragment according to the conversion of key bit, when making it key bit with this lock and matching, must overlap with locking card key position, pressure just constitutes coilable unblanking in locking card key is subjected to; Be equipped with at each shell fragment and make its interior pressure element that resets or extrapolation element, press in these elements or extrapolation element all to be loaded in grooves hole of lock core shell fragment; Described locking card key is single or symmetrically arranged two, be installed in the middle of the line of demarcation of lock body and active lock core, below locking card key, be provided with draw key, when unblanking, the part of this draw key can be inserted in the keyway of single shell fragment, maybe can insert double shell fragment and be overlapping in the keyway that connects; When shutting, the top of draw key has constituted a non-lock key insertion lockhole and can arbitrarily reverse 360 ° structure just in time at the edge of active lock core.At the turning set of double-row type structure and initiatively between lock core lining can be housed.

Although the turning set on the idle-run lock pin engages with shifting block, but can only make lock core relatively rotate cover idle running when unblanking, can not unblank, have only the use matched key owing to the use non-matching key, turning set and lock core are rotated together, drive shifting block and rotate the switch of realizing lock.

The improved tapered end of the utility model is compared with existing tapered end owing to adopt idle-run lock pin, make its prevent skilled unlocking and and the performance of destructive picking lock be further enhanced.

Further specify technical solutions of the utility model below in conjunction with accompanying drawing.

The specific embodiment

The improved tapered end of the utility model is seen Fig. 1, Fig. 2 and Fig. 3, one lock body 1 is arranged, two in the lock body 1 is provided with the idle-run lock pin of same structure, the end of each lock core turning set 3 all is fixed with shifting block 2, idle-run lock pin is made up of active lock core 9 and turning set 4, initiatively lock core 9 is enclosed within the turning set 4, and turning

set

4 and 9 of lock cores of active are equipped with lining 5; Be provided with shell fragment 6 in the groove of the hole of active lock core 9, plurality of rows shell fragment 6 is arranged along lock core shaft's line parallel, and each row's tool is staggered and partly overlapping double shell fragment the two-sided keyway 8 that all has on each shell fragment 6; Be equipped with at each shell fragment 6 and make its interior pressure element stage clip 7 that resets, press elements all to be loaded in grooves hole of lock core shell fragment 6 in these; Locking card key 10 is symmetrically arranged two, be installed in the middle of the line of demarcation of lock body 1 and active lock core 9, below locking card key 10, be provided with

draw key

11,12, when insertion matched key 13 was unblanked, the part of this

draw key

11,12 can be inserted the keyway interior (referring to Fig. 4) that double shell fragment 6 is overlapping and connects; When shutting, the top of

draw key

11,12 has constituted a non-lock key insertion lockhole and can arbitrarily reverse 360 ° structure just in time at the edge of active lock core 9 (referring to Fig. 2).

Claims

1, a kind of improved tapered end comprises lock body, and the two in the lock body is provided with the idle-run lock pin of same structure, and it is characterized in that: the end of each lock core turning set is fixed with shifting block;

Described idle-run lock pin is made up of active lock core and turning set, initiatively lock core is enclosed within the turning set, in the groove of the hole of active lock core, be provided with shell fragment, the plurality of rows shell fragment is arranged along lock core shaft's line parallel, each row has single shell fragment or is staggered and partly overlapping double shell fragment, single face or the two-sided keyway that all has on each shell fragment, this keyway decides the keyway deviation post of each shell fragment according to the conversion of key bit, when making it key bit with this lock and matching, must overlap with locking card key position, pressure just constitutes coilable unblanking in locking card key is subjected to; Be equipped with at each shell fragment and make its interior pressure element that resets or extrapolation element, press in these elements or extrapolation element all to be loaded in grooves hole of lock core shell fragment; Described locking card key is single or symmetrically arranged two, be installed in the middle of the line of demarcation of lock body and active lock core, below locking card key, be provided with draw key, when unblanking, the part of this draw key can be inserted in the keyway of single shell fragment, maybe can insert double shell fragment and be overlapping in the keyway that connects; When shutting, the top of draw key has constituted a non-lock key insertion lockhole and can arbitrarily reverse 360 ° structure just in time at the edge of active lock core.
