Description

A kind of lockset

Technical field

The utility model relates to a kind of technical field of lockset, is specifically related to a kind of blade lockset.

Background technology

The lock core of existing lockset is made up of single lock cylinder, in the pellet shot from a slingshot hole of lock core, by several groups of pellets shot from a slingshot of just arranging, is withstood by spring, and when key inserted lock core, key tooth top that extracts can rotate lock core, thereby opens lock.When extracting key, resilience in spring top resets pellet shot from a slingshot, stops lock core to rotate.This lock core is opened simple, and key is prone to join, and is stolen easily.

The utility model content

The purpose of the utility model is in order to improve the theftproof performance of lockset, and a kind of rational in infrastructure, lockset of transreplication not is provided.

The purpose of the utility model is to realize like this.

A kind of lockset; Comprise lock core, blade part, Lock Part and lock core cover; Said lock core has key hole vertically, and the vertical direction of key hole is provided with the locking groove, has a plurality of blade grooves on the sidewall of key hole; A plurality of blade grooves are along the axially-aligned of key hole, and through key hole; Said blade part comprises blade and spring; Be respectively equipped with the location division on the transverse sheet of blade and unblank groove, the location division places the bottom surface of blade transverse sheet, and the groove of unblanking places the end face of blade transverse sheet; Blade and spring are installed in the blade groove in the lump; Blade inserts the blade groove and is horizontally through key hole, and the location division of blade places in the said key hole, and the groove face of unblanking of blade is to said locking groove; Said Lock Part comprises locking rod, spring and mounting, and locking rod is put into the locking groove, and locking rod is compressed on the transverse sheet of said multi-disc blade by spring; The lock core cover is inserted in the lock core that Lock Part and blade part are installed.The inwall of said lock core cover is provided with lock slots.The outer wall of said lock core cover is provided with spacing protuberance.

Insert correct key, key and lock core coincide, and the locking rod of the unblank groove and the Lock Part of its blade part is on the same axis, and locking rod falls into the groove of unblanking, and locking rod leaves the lock slots of lock core cover, and lock core is rotatable, realizes unblanking.Insert wrong key, key and lock core are misfitted, and the locking rod of the unblank groove and the Lock Part of its blade part can not be on the same axis, and locking rod still is stuck in the lock slots of lock core cover, and lock core can not rotate, and realize locking.

Technique scheme also can be done following further perfect.

Said blade one side is provided with protuberance, and the position of the corresponding blade protuberance of said blade groove is provided with installing hole, and said spring is placed in the installing hole and is suppressed by the blade protuberance.The spring significant feature is that blade is resetted, and spring makes blade be in initial position, and locking rod does not have the space and falls in the groove of unblanking of blade, realizes locking.

Saidly in the blade groove, be provided with a pair of blade part, be reverse setting, blade be divided into outer mill the tooth blade with in mill the tooth blade.The reverse setting is in order to design two lock roads, to improve the safety of lockset, making it be difficult for being replicated.

The location division of said each sheet blade is all inequality with the groove position of unblanking.Many for the variation of milling tooth that makes the key that cooperates lockset like this, repetitive rate is low, thereby makes key also be difficult for being replicated.

The groove shape of unblanking of said blade is V-shaped.The bottom shape of said locking rod cooperates with the groove shape of unblanking of blade.The groove of unblanking of the bottom of locking rod and blade all is a V-arrangement, and when the groove of unblanking of blade was on the same axis, the bottom of locking rod was fallen in the groove of unblanking of blade, and locking rod is the lock slots of release lock core retainer plate simultaneously, and lock core is rotatable, realizes unblanking.

Said locking rod two ends are respectively equipped with omission, and spring places in the omission and covered by mounting.The main effect of spring is that locking rod is compressed on the transverse sheet of said multi-disc blade; When the groove of unblanking of blade was on the same axis, the thrust of spring was fallen in the groove of unblanking of blade the bottom of locking rod, and locking rod is the lock slots of release lock core retainer plate simultaneously; Lock core is rotatable, realizes unblanking.

The beneficial effect of the utility model is.

The utility model provides a kind of lockset; Its through many groups mill outward the tooth blade with in mill tooth blade combination and use, lockset need to unblank many group blades to be in simultaneously on the same axis, could realize unblanking; Otherwise; Lockset can not be opened, this rational in infrastructure and transreplication not, thereby the safety that has improved lockset.

The specific embodiment

Below in conjunction with accompanying drawing utility model is done further to detail.

To shown in Figure 12, a kind of lockset comprises lock core 1, blade part 2, Lock Part 3 and lock core cover 4 like Fig. 1.

Extremely shown in Figure 4 like Fig. 1; Said lock core 1 has key hole 101 vertically; The vertical direction of key hole 101 is provided with locking groove 102; Have a plurality of blade grooves 103 on the sidewall of key hole 101, a plurality of blade grooves 103 are along the axially-aligned of key hole 101, and through key hole 101.

Like Fig. 5 and shown in Figure 6; Said blade part 2 comprises blade 201 and spring 202; Be respectively equipped with location division 204 on the transverse sheet 203 of blade 201 and unblank groove 205, location division 204 places the bottom surface of blade 201 transverse sheets 203, and the groove 205 of unblanking places the end face of blade 201 transverse sheets 203; Blade 201 is installed in the blade groove 103 with spring 202 in the lump; Blade 201 inserts blade groove 103 and is horizontally through key hole 101, and the location division 204 of blade 201 places in the said key hole 101, and the groove 205 of unblanking of blade 201 is towards said locking groove 102.

Extremely shown in Figure 9 like Fig. 7; Said Lock Part 3 comprises locking rod 301, spring 302 and mounting 303; It is vacant 304 that said locking rod 301 two ends are respectively equipped with, and locking rod 301 is put into locking groove 102, and spring 302 places in the omission 304 of locking rod 301 and covered by mounting 303.Locking rod 301 is compressed on the transverse sheet 203 of said multi-disc blade 201 by spring 302.
