Abstract

The utility model relates to a multi-purpose lockset latch belonging to the field of cylinder locksets. The lockset latch mainly comprises an inner lock core, an outer lock core and a cylinder storage which are assembled in a lock body, a circular lock hole which is formed by the intervals of the inner and the outer lock cores, and an annular key which can be inserted with a lock hole and can open the lockset. The lockset latch adopts the annular key by corresponding the shape of a jack and the distribution characteristics of the cylinder storage in the lock latch. The lockset with the structure has the characteristics of reasonable structural design, strong safety performance and long service life, etc., and is easily matched with other lockset accessories.

Description

A kind of lockset head of using more

The utility model belongs to the cylinder type lockset, is a kind of lockset head of using more.

It mainly locks and opens member by the lock core that is installed in the lock body at present common cylinder lock lockset, is assemblied in the lock body pellet shot from a slingshot in the marble bin and constitutes with each pellet shot from a slingshot length and the corresponding sheet key of lock core jack.Though this kind lockset head can be assembled into the lockset of various different purposes with all kinds of locking bars, insurance, cryptographic attachment phase configuration, exist to protect and remove poor-performing, key frangibility and function are more single, the deficiency that waits simple in structure.

The purpose of this utility model is to provide a kind of multipurpose lockset head, the main member of this lockset head is: be assemblied in inside and outside lock core, marble bin in the lock body, also can open the ring-type key of lockset by the garden shape lockhole that inside and outside lock core forms at interval with pegging graft with lockhole.This lockset head be easy to encrypt and can with various locking bars, the supporting assembling of insurance annex.To overcome the existing in prior technology deficiency.

Overall structure of the present utility model is:

A kind of lockset head of using by lock core more, marble bin and corresponding with it key are that main assembly forms, it is characterized in that the lock core that is arranged in lock body 1 lock core cavity 2 is divided into, outer lock core 3,4 two parts, in, the outer lock core coaxial package, each interval forms the ring-type lockhole 6 of grafting ring key 5, the port 7 of ring key is offered and marble bin, the dentation of the concavo-convex cooperation of each pellet shot from a slingshot in the lockhole, effectively the marble bin 8 of quantity is assemblied in the lock core cavity, be distributed between lock core cavity wall and the internal cylinder wall, matched in clearance each other, spring and each pellet shot from a slingshot that is disposed place in the marble bin respectively and each vallecular cavity 9 of key lock bore ends, each align member of marble bin is respectively: the collar 10 in being plugged in the retainer upper periphery wall groove, be plugged on the alignment pin 11 in some grooves on the lock core cavity wall, in each groove 12 on each alignment pin other end insertion marble bin periphery wall; Each marble bin upper end also is provided with cover plate 13, in the vallecular cavity of the end of three key lockholes, encapsulate fixedly pellet shot from a slingshot 14 at least, offering slotted eye 16 near on internal cylinder chamber 15 walls on lock core cavity top, lock core dowel 17 is installed, in the groove 18 on the other end insertion internal cylinder outside wall surface of alignment pin in the slotted eye.

All the other each annexes also have:

If assembling password locking lamination on the shift fork 19 of internal cylinder end, then the outer lock core port has locking ring 20, and the alignment pin 11 of marble bin be that 3-5 is individual, be plugged on the lock core cavity wall on each groove in, and uniform on wall, the encapsulation fixedly chamber groove and the pellet shot from a slingshot wherein of pellet shot from a slingshot is 2-3.

On near the lock body of outer lock core bottom and be carved with sign trace note 21 on the key.

Accompanying drawing of the present utility model has: the cross-section structure sketch of using lockset head more.

Accompanying drawing has provided embodiment of the present utility model, further specifies as follows in conjunction with the accompanying drawings:

If the annex that disposes with this lockset head is straight formula or U-shape lock bar, then the open theory of this lockset head and conventional cylinder lock are basic identical.Only open this lockset head, and the key that makes the common rotation of inside and outside lock core is the garden shape key with end handle 22, insert in the corresponding lockhole by garden shape key, and by each the movable pellet shot from a slingshot that presets and the fixing dentation port of pellet shot from a slingshot and key after concavo-convex the cooperation, the inside and outside lock core of turn makes the shift fork of internal cylinder end stir lock pin unlatching locking bar.The synchronous rotation of inside and outside lock core interleaves the back that cooperatively interacts, fixedly pellet shot from a slingshot and on the key corresponding recessed position in the bore ends vallecular cavity and realizes by being distributed on inside and outside lock core, by each the fixedly position and quantity decision of pellet shot from a slingshot, angle so that key and inside and outside lock core in the variation unlatching locking bar process turn over can change in 0 ° of-360 ° of scope.The sign indentation of indentation sign on it with the lock body bottom surface of close lock core should be alignd when inserting key, otherwise key can't insert, this is because the fixedly pellet shot from a slingshot in this lockset must be meshing with each other with recessed accordingly position on the key, also can indicate indentation, as long as the user remembers that on the key being aided with the direction indication again with fixing corresponding each recessed portion of pellet shot from a slingshot can finish unlocking action, this is the encryption function of this lockset head.

In addition, if shift fork and the assembling of the locking lamination on the conventional safety cabinet dial with the internal cylinder end, and the sequence number of on internal cylinder, finishing according to the fixing arrangement regulation of pellet shot from a slingshot, insert outer lock core in rotating behind the key and can have combination disk identical functions with safety cabinet, and combination disk and lockset are united two into one.

The obtained technological progress of the utility model is: this lockset is by changing the structure of lock core With shape and the ring-type key with matching of key hole be main member, to former pellet Flat lockhole and the key of lock have carried out bigger improvement, simultaneously to marble bin in the lock body Structure is done corresponding change, is beneficial to encrypt and increase the intensity of key. In addition this lockset with The coded lock internals that safety cabinet is used supports the use, and can greatly simplify the structure of coded lock, Therefore the utlity model has reasonable in design, the strong and long service life of safety performance, Be easy to and the characteristics such as other locksets are supporting.
