Abstract

The utility model relates to an improved lockset, which is composed of a lock core, a sleeve, clamping pins, and a key. The improved lockset is characterized in that the end surface of the clamping pin which is convexly exposed in a key hole of the improved lockset is designed into an inclined wall surface, and the key is provided with an inclined matching surface which is corresponding to the inclined wall surface. The inclined matching surface is provided with a plurality of contraposition grooves which are respectively corresponding to each clamping pin, and the clamping pins are pushed to an unlocking position. The lockset structure is suitable for locksets with various types, the lock core is rotated to any positions, and the key can outwards drawn. The improved lockset is more convenient in use, and the difficulty degree of illegal unlocking can be increased.

Description

A kind of improved lockset

The utility model relates to lockset, refers to a kind of illegal release degree of difficulty and improved more easily lockset of use of increasing especially.

Lockset is made of core and sleeve, utilize the blocking tip to give the blocking locking between core and the sleeve, core is provided with keyhole, for after the key insertion blocking tip top being moved to unlocked position, make between core and the sleeve and being relatively rotated, present lockset on the market, its keyhole is to be one just rectangular poroid, that is the hole wall of this keyhole is to be horizontal plane or vertical plane, therefore, respectively pushing away the tip is the protruding keyhole inside that is exposed to that flushes, and makes the burglar promptly do a judgement according to neat keyhole easily, by this lockset of unlocked by universal key, cause this lockset to lose its due anti-theft feature.

And, traditional lockset, is indentation by key with pushing away the end face that the tip cooperates, except key turns to locking condition, outside key can be extracted out, after the key insertion is rotated away from locking condition, push away the tip and promptly can't retreat, make key be subjected to pushing away the blocking of the tip, and can't extract out, particularly since conventional lock under released state, core and sleeve and no-fix make the user of service judge by accident easily, and, conventional lock is under the released state, can't not need key to cooperate mostly and core can be turned to locking position, causes to use and goes up sizable inconvenience.

Therefore, main purpose of the present utility model is to provide a kind of degree of difficulty that can increase illegal release, and core turns to arbitrary position key and all can outwards detach use " improved lockset " more easily.

For this reason, the utility model be with the blocking tip in the keyhole of lockset the end face of protruding dew all be designed to inclined wall, and make key have corresponding oblique fitting face, this oblique fitting face is provided with a plurality of alignment grooves and corresponds respectively to each blocking tip, in order to the blocking tip is passed to unlocked position, this kind lock structure is applicable to the lockset of various ways, is the design that non-flush type is arranged by each blocking tip, can improve the degree of difficulty of illegal release.

On the side wall surface of keyhole of the present utility model and key, corresponding groove or raised line can be set hide the blocking tip.

The utility model has the advantages that: be applicable to the lockset of various ways, can improve the degree of difficulty of illegal release, and core turns to arbitrary position, key all can be extracted out from keyhole freely, can't be subjected to the interference of the blocking tip, has more ease of use.

Relevant detailed construction of the present utility model and effect will make it more clear and definite by following detailed description, consult appended each figure simultaneously, and it is clear that technology contents of the present utility model is further disclosed.

Fig. 8 is the key schematic diagram of the utility model the 7th embodiment.

At first cooperate shown in Figure 2ly as Fig. 1, the utility model " improved lockset " is made of core 10, sleeve 20, the blocking tip 30 and key 40, wherein:

Cooperate spring 31 that the two is given the blocking locking by the blocking tip 30 between core 10 and the sleeve 20, locking therebetween or release mode and principle are general known technology, do not repeat them here; Core 10 is provided with keyhole 11, and the end face 12 for 30 protruding dew of the blocking tip in this keyhole 11 all is designed to inclined wall;

Key 40 is provided with oblique fitting face 41 corresponding to above-mentioned inclined end face 12, and this oblique fitting face 41 is provided with some alignment grooves 42 and corresponds respectively to each blocking tip 30, in order to the blocking tip 30 is passed to unlocked position.

The utility model is after assembling, because the end face 12 for the blocking tip 30 protruding dew in the keyhole 11 is inclined wall, therefore the blocking tip 30 is inequal arrangement in keyhole 11, use the degree of difficulty that increases the illegal release of burglar, in addition, on the side wall surface of keyhole 11 and key 40, corresponding groove can be set or raised line 43 is hidden the blocking tip 30, can further promote illegal release degree of difficulty.

In addition, because the end face that cooperates for the blocking tip 30 on keyhole 11 of the present utility model and the key 40 is to be skewed, therefore, no matter core 10 turns to any position, key 40 all can be extracted out from keyhole 11 freely, can't be subjected to the interference of the blocking tip 30, this characteristic can be promoted ease of use.

The lockset of the tabular key that the utility model is easily seen on can be applicable to above-mentioned market, also applicable to the lockset (as shown in Figure 3) of the flange shape key 40 of flat board, the lockset (as shown in Figure 4) of dull and stereotyped caulking groove shape key 40, the lockset (as shown in Figure 5) of cross key 40, the lockset (as shown in Figure 6) of flexible tabular key 40, the lockset (as shown in Figure 7) of round bar shape key 40, the lockset (as shown in Figure 8) of the shaft-like key 40 of semicircle all can reach identical purpose.

In sum, the utility model " improved lockset ", can be applicable to the lockset of various ways by identical architectural feature, and core turns to arbitrary position key and all can outwards detach, have ease of use, and can increase the degree of difficulty of illegal release, have the raising on the effect, for this reason, patent application is proposed in accordance with the law.

Claims

1, a kind of improved lockset, constituted by core, sleeve, the blocking tip and key, cooperate spring that the two is given the blocking locking by the blocking tip between core and the sleeve, core is provided with keyhole, after supplying key to plug together the blocking tip is passed to unlocked position, it is characterized in that: in this keyhole for the blocking tip the end face of protruding dew be set as inclined wall, key is provided with oblique fitting face corresponding to above-mentioned inclined end face, this oblique fitting face is provided with a plurality of alignment grooves and corresponds respectively to each blocking tip.
