Abstract

The utility model particularly relates to an improved structure of a door lock, which comprises a lock casing, a lock liner, and double-row main beads arranged in the lock liner, wherein both sides of the double-row main beads are respectively matched with moving combs which are movably embedded in a through groove reserved at the body wall of the lock liner; a spacing holding groove is arranged on the inner wall of the lock casing; the moving combs can walk between the double-row main beads and the spacing holding groove. The utility model has the technical scheme that the lock liner can rotate only by the method that the moving combs work together with the lock bead after a key is inserted in a lock hole for unlocking, avoiding unsafety of the prior art that the key can unlock the lock only by matching with the lock bead and increasing the safety of the door lock class.

Description

A kind of structure-improved of door lock

Technical field:

The utility model mechanical lock technical field is refered in particular to the more reasonably structure-improved of door lock of a kind of structure.

Background technology:

Traditional mechanical door lock is the unlatching that realizes door lock by the tartar cooperation lock pearl of key, but traditional mechanical lock is to open by upper and lower pearl activity, therefore is easier to use other TOs; It is poor perhaps with the omnipotent spoon of broach shape all pearl all to be pushed pellet shot from a slingshot, and making in the pellet shot from a slingshot hole does not have pellet shot from a slingshot, thereby will lock runin.For making lockset prevent runin, people have found out many kinds of structure designs, but notice generally concentrates on spoon face tartar and corresponding bullet groove thereof, on the pellet shot from a slingshot hole, makes the anti-runin ability of lock gall can not get effective improvement; Though what have is effective, cost is extremely expensive, and structure is too complicated.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of door lock structure-improved of rational in infrastructure, anti-runin is provided.

For achieving the above object, the technical scheme that the utility model provides is: include lock housing, lock gall and pack the interior double main pearl of lock gall into, the both sides of double main pearl are combined with the row comb respectively, row comb activity is embedded in the groove that the body wall of lock gall reserves, be preset with spacing holding tank on the inwall of lock housing, the row comb can be walked between double main pearl and spacing holding tank, thereby changes the mode that the lock pearl is opened lock.

After the utility model adopts technique scheme, after key inserts lockhole, have only the row comb to cooperate the lock pearl to work together and lock gall could be rotated, thereby open, avoided only insecurity of a prior art key, the safety that has improved this type of lock by cooperating the lock pearl can open lock gall.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further,

Accompanying drawing 1 is the utility model (not showing lock housing) structural profile schematic diagram;

Accompanying drawing 2 is the utility model structure side diagrammatic sketch;

Accompanying drawing 3 is the utility model lock-shell structure schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further, see shown in accompanying drawing 1～accompanying drawing 3, preferred embodiment of the present utility model include lock housing 1, lock gall 2 and the lock gall 2 of packing in double main pearl 3, the both sides of double main pearl 3 are combined with row comb 4 respectively, in the groove 5 that the body wall that row 4 activities of combing are embedded in lock gall is reserved, be preset with spacing holding tank 6 on the inwall of lock housing 1, row comb 4 can be walked between double main pearl 3 and spacing holding tank 6.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.

Claims

1, a kind of structure-improved of door lock, include the double main pearl (3) in lock housing (1), lock gall (2) and the lock gall of packing into (2), it is characterized in that: the both sides of double main pearl (3) are combined with row comb (4) respectively, in the groove (5) that the body wall that row (4) activity of combing is embedded in lock gall is reserved, be preset with spacing holding tank (6) on the inwall of lock housing (1), row comb (4) can be walked between double main pearl (3) and spacing holding tank (6).
