Description

Lockset and key thereof

Technical field

The present invention refers to a kind of can the group under the design of lock and teeth groove length at each especially about a kind of lockset and key thereof, further changes lockset and the key thereof that more kinds of different locksets and key utilize for the user.

Background technology

Lockset be a kind of can be in order to the protection personal belongings, safeguard the apparatus of individual privacy, open this lockset thereby the specific keys that mat one and this lockset collocation are used can be inserted and rotated, guarantee safety of goods to reach, prevent the effect that is stolen.

Referring to shown in Figure 8, lockset 30 and key 40 thereof for a kind of prior art, this lockset 30 mainly is axially to run through to be provided with a core 32 in a hollow lock housing 31, the hole wall indent of the keyhole 311 that these lock housing 31 front ends are set is formed with an outside fix groove 312, on the ring wall face of this core 32 also indent be formed with and this outside fix groove 312 corresponding in locating slots 321, wherein, these core 32 internal arrangement are provided with the complex root lock;

The axial projection of a wherein end of this key 40 is formed with a ring-like sleeve 41, on the outside wall surface of this sleeve 41 and locate projection respectively near the end on the internal face and form an outer nose 42 and an interior nose 43, should be mutual correspondence in position outer, interior nose 42,43, in addition, on the outside wall surface of this sleeve 41 near end place spacer ring around and indent form a plurality of teeth groove 411, the length of each teeth groove 411 is different, and respectively to should lockset lock in 30.

Be with, when the sleeve 41 with key 40 inserts in the keyhole 311 of these lock housings 31, should outer nose 42 be that correspondence is passed through this outside fix groove 312, should interior 43 correspondences of nose penetrate and be fastened in 321 of this interior locating slots, promptly this key 40 must can insert in the keyhole 311 of this lock housing 31, again with a specific angle direction, design by the different teeth groove 411 of length, after can promoting respectively to organize lock and moving the distance that does not wait, and then drive this core 32 and rotate, unblank.

Wherein, utilize variation, the arrangement of 411 different lengths of teeth groove of lock set on this core 32 and key 40, the key 40 that goes out 800,000 groups of different locksets 30 and be mated approximately capable of being combined is bought use for the user; Yet; the user buys lockset 30 and key 40 protects the demand of its personal belongings to increase day by day; though and the combination of lock change in length can reach 800,000 kinds; but its restriction is arranged so; how can further increase the variation and the combination of this lockset and key; so that this lockset 30 can reach the protection article, prevent the effect that article are stolen that reality is our problem demanding prompt solution place really.

Summary of the invention

Because aforementioned the deficiencies in the prior art the invention provides a kind of lockset and key thereof, the uncommon design by this with the variation that reaches this lockset of further increase and key, the goal of the invention of combination.

In order to reach above-mentioned goal of the invention, the technological means that the present invention utilized is for providing:

One lockset, it includes the core that a hollow lock housing and is located at this lock housing inside, spacer ring is established and is directly concaved and forms at least one outside fix groove on the hole wall of the keyhole that this lock housing front end face is set, close front end spacer ring is established and is directly concaved and forms at least one interior locating slot on this core ring wall face, wherein, outside fix groove of locating slot and this lock housing is the staggered kenel that is provided with in this;

One key that is used with this lockset, the axial projection of one end is formed with a sleeve, on the outside wall surface of this sleeve and the internal face respectively spacer ring establish and radially projection form at least one outer nose and at least one in nose, wherein, nose and kenel that should the wrong setting of outer nose submission in this.

When the sleeve of this key is inserted in the keyhole of lock housing, when making this outer nose correspondence pass through outside fix groove in this lock housing, in this nose also simultaneously correspondence wears and is fastened between the interior locating slot of this core.

The invention has the advantages that can be further by the quantity and the angle position of the inside and outside nose of the inside and outside locating slot that changes this lockset and this key; make under the design of each group lock and teeth groove length; can also further change and more kinds of different locksets and key utilizes for the user; avoid repetition, make this lockset can reach the protection article really, prevent the effect that article are stolen.
