Description
Technical field
The present invention relates to a kind of lock core with sequin combined cipher lock pearl.
Background technology
Lock is the article that cannot leave in people's daily life, the mankind use lock to preserve important article since ancient times always, make the property of oneself can not be stolen by others, and the antitheft position of core of lock is exactly lock core structure, the performance quality of lock core structure directly has influence on the theftproof performance of whole lockset.In existing lockset, lock core structure generally comprises mutually adaptive lock gall, key, is provided with and can inserts the keyhole that key carries out opening lock master or the operation of locking lock core in lock gall.Between existing lock core structure general only by being located at row's hoodle in lock gall or cipher chips, be located at ball race on the key as latch-up structure, such latch-up structure design is too simple, common unlocking tool just easily can carry out skilled unlocking, anti-theft feature is poor, use reliable and stable not, security performance is lower, and security protection effect is poor.Secondly, due to hoodle or cipher chips negligible amounts, coded number is less, key mutual opening rate and repetitive rate higher, easily occur the situation of a key and multiple lockset adaptation or multiple key and a lockset adaptation, structure is too simple, easily copied, the theftproof performance of lockset is lower.In addition, the structure that part lock gall adopts two panels sequin to combinationally use to improve coded number, the width of the password groove of lock gall is comparatively large, quantity is more and cause lock core structure intensity lower, easily rotten by sled.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of lock core with sequin combined cipher lock pearl, coded number is many and be difficult to technical unlocking, and safety is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of lock core with sequin combined cipher lock pearl, include lock housing, lock gall, dead bolt and several hoodle assemblies be arranged on the upside of lock housing, described hoodle assembly includes pearl spring, flat pearl, multiple password groove corresponding with hoodle module position is provided with vertically on the upside of described lock gall, the lock gall left and right sides is connected with bar shaped spacer, described lock housing be provided be positioned at the left and right sides and with the locating slot of described bar shaped spacer adaptation, coded lock pearl is provided with in described password groove, described coded lock pearl comprises the decorative pearl on top of an official cap of a cylindricality, the both sides of the described decorative pearl on top of an official cap are respectively provided with a chute, in described chute, cipher chips is installed, described cipher chips arranged outside has the bayonet socket with described bar shaped spacer adaptation, described cipher chips inside lower end is provided with the ladder coordinated with the key bit of key.
As the improvement of technique scheme, described password groove is provided with five.
As the further improvement of technique scheme, two cipher chips of each described coded lock pearl are different.
Further, described lock gall afterbody is provided with the groove for connecting dead bolt.
Further, described groove is arranged along the axis of lock gall.
The invention has the beneficial effects as follows: coded lock pearl adopts a decorative pearl on top of an official cap to add the structure of two cipher chips, a coded lock pearl just has 3 passwords, 15 passwords are then had as adopted 5 coded lock pearls, greatly improve coded number, reduce key mutual opening rate and repetitive rate, can have more coded number owing to being provided with 5 password grooves, the fluting quantity reduced on lock gall improves the structural strength of lock gall, improve by the rotten difficulty of sled, improve safety; The decorative pearl on top of an official cap controls hoodle assembly, and two cipher chips control two bar shaped spacers, multi-position locking, key must be used all to boost the decorative pearl on top of an official cap and cipher chips could be opened, greatly developing skill property unlatching difficulty, the theftproof performance of raising lockset; Cipher chips does not adopt spring reset, its drag reduction inserted key, reduces the key bit wearing and tearing of key, improves application life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is decomposition texture schematic diagram of the present invention;
Fig. 2 is the structural representation of coded lock pearl in the present invention.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 2, a kind of lock core with sequin combined cipher lock pearl, include lock housing 1, lock gall 2, dead bolt 6 and several hoodle assemblies 3 be arranged on the upside of lock housing 1, described hoodle assembly 3 includes pearl spring 301, flat pearl 302, multiple password groove 201 corresponding with hoodle assembly 3 position is provided with vertically on the upside of described lock gall 2, lock gall 2 left and right sides is connected with bar shaped spacer 4, described lock housing 1 be provided be positioned at the left and right sides and with the locating slot 101 of described bar shaped spacer 4 adaptation, coded lock pearl 5 is provided with in described password groove 201, described coded lock pearl 5 comprises the decorative pearl on top of an official cap 51 of a cylindricality, the both sides of the described decorative pearl on top of an official cap 51 are respectively provided with a chute 511, in described chute 511, cipher chips 52 is installed, described cipher chips 52 arranged outside has the bayonet socket 521 with described bar shaped spacer 4 adaptation, described cipher chips 52 inside lower end is provided with the ladder 522 coordinated with the key bit of key.Adopt said structure, 1 coded lock pearl 5 comprises 1 decorative pearl on top of an official cap 51 and 2 cipher chips 52, and namely 1 coded lock pearl 5 just has 3 passwords mutually to combine, general lock gall 2 arranges 5 coded lock pearls 5, just have 15 passwords, and to be 3 be one group first combines the combination of adding 5 groups, coded number promotes greatly, the difficulty of developing skill property unlatching greatly, strengthen the safety of lockset, simultaneously because coding book is more, quantity that lock gall 2 slots to obtain can be reduced, strengthen structural strength, prevent from being prized; The decorative pearl on top of an official cap 51 of coded lock pearl 5 and cipher chips 52 corresponding hoodle assembly 3 and bar shaped spacer 4 respectively, lock gall 2 has three retaining mechanisms, it is better that anti-violence opens performance, and coded lock pearl 5 is arranged in the top of lock gall 2, the decorative pearl on top of an official cap 51 and cipher chips 52 are fallen after rise by gravity and reset, need not mounting spring, the friction of key bit and coded lock pearl 5 when alleviating plug key, reduce the wearing and tearing of key bit, improve application life.
In the present embodiment, preferably, described password groove 201 is provided with five.
In the present embodiment, preferably, two cipher chips 52 of each described coded lock pearl 5 are different, can improve the complexity of coding, strengthen technical unlocking difficulty, improve security performance.
In the present embodiment, preferably, described lock gall 2 afterbody is provided with the groove 202 for connecting dead bolt 6.Preferably, described groove 202 is arranged along the axis of lock gall 2.Adopt said structure, lock gall 2 rotates and namely drives dead bolt 6 to rotate, and structure is simple, easily assembled.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
