Abstract
The utility model relates to a location mechanism for a lock and a key, which comprises a key, a lock shell and a teeth-flower blade that is arranged in the lock shell and engages with the key and a lock core axis. The width of the key jack in the lock shell is smaller that the width of the key sheet media that is provided with two symmetrical breaks grooves that engage with the key jack. The utility model overcomes the problem that in the prior arts an efficient location mechanism is lacked between the lock and the key, which causes the weak reliability, high error rate and easy damaged of the lockset, via the design, the key can only move under the circumstance that the key is inserted into the right place, which prevents the abnormal unlock efficiently and has the advantages of simple structure, correct location, excellent performance of reliability, excellent effect of theft-proof ad convenient employment or the like.
Description
Affiliated technical field
The utility model relates to the detent mechanism of a kind of tapered end and key.
Background technology
At traditional lockset, particularly be suitable in the lockset tapered end of tartar blade, all lack the detent mechanism that effectively matches with key, under user mode, key also is not inserted into the position often, and is just rotatable, therefore, the poor reliability of above-mentioned lockset, fault rate height, as easy as rolling off a log damage.
Summary of the invention
To lack effective detent mechanism in the prior art between the tapered end and key in order overcoming, to cause poor reliability, the fault rate height of lockset, the problem of as easy as rolling off a log damage.The utility model provides the detent mechanism of a kind of tapered end and key, simple in structure, the accurate positioning of this tapered end and key positioner mechanism, good reliability.
The technical scheme that its technical problem that solves the utility model adopts is: comprise key, tapered end housing and be installed in tartar blade and the lock core shaft that matches with key in the tapered end housing, the width of the key hole on the tapered end housing also is provided with the gap slot that matches with key hole less than the width of key inserted sheet on the key inserted sheet.
Gap slot on the key inserted sheet is symmetrical arranged two.
The utility model is by above-mentioned design, but makes only normal rotation just under the state that is inserted into the position of key, effectively prevented unnormal unlocking, has simple in structure, accurate positioning, good reliability, good anti-theft effect, advantage easy to use.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the left view of tapered end.
The specific embodiment
As shown in the figure, the utility model comprises key 1, tapered end housing 2 and is installed in tartar blade 3 and the lock core shaft 4 that matches with key 1 in the tapered end housing 2, the width 6a of the key hole 5 on the tapered end housing 2 is less than the width 6b of key inserted sheet 7, also be provided with the gap slot 8 that matches with key hole 5 on the key inserted sheet 7, the gap slot 8 on the key inserted sheet 7 is symmetrical arranged two.Under user mode, if key 1 is not inserted into the position, because the width 6a of key hole 5 is less than the width 6b of key inserted sheet 7, key 1 is limited to rotate, only be inserted under the situation of position at key 1, the gap slot 8 on the key inserted sheet 7 is relative with key hole 5, and key 1 could normal rotation.
Claims (2)
1, the detent mechanism of a kind of tapered end and key, comprise key, tapered end housing and be installed in tartar blade and the lock core shaft that matches with key in the tapered end housing, it is characterized in that the width (6b) of the width (6a) of the key hole (5) on the tapered end housing (2), also be provided with the gap slot (8) that matches with key hole (5) on the key inserted sheet (7) less than key inserted sheet (7).
2, the detent mechanism of tapered end according to claim 1 and key is characterized in that the gap slot (8) on the key inserted sheet (7) is symmetrical arranged two.
