Abstract
The utility model relates to a tool to lock, especially a blade type tapered end and rather than key of looks adaptation, should include cylindrical lock core, lock core shell, blade and leaf spring, the lock core axial is equipped with the key hole, and the lock core radially is equipped with that a plurality of radially communicates with each other the blade stores the chamber and the leaf spring stores the chamber, stores the intracavity at every blade and is equipped with two blade of motion in opposite directions, is equipped with the oblate slot hole that corresponds with the key on every blade, with the mutual asymmetry of both sides tooth of the key of tapered end looks adaptation. Because two blades moving in opposite directions are arranged in each blade storage cavity to form a bidirectional blade structure, the mutual opening rate is greatly reduced, and the slotted hole on each blade is a flat square slotted hole, so that the blades and the key are easy to process, and the cost is relatively low.
Description
Technical field
The utility model relates to a kind of lockset, especially a kind of vane type tapered end and the key suitable with it thereof.
Background technology
Common blade formula lockset generally all is that the side at columniform lock core cylinder is arranged in parallel vertically and offers several blades storage chambeies and leaf spring storage chamber, in each blade storage chamber a slice blade is set, each blade is provided with the slotted eye that the identical upper-lower position with keyhole in cross section differs, when key inserts, when the profile of tooth of key is correct, the end face of all blades just in time flushes with the lock core cylinder, and core can drive stop with the key rotation and unblank in lock core shell.This its mutual opening rate of vane type lockset is higher, theftproof performance is poor, China Patent No. is 02263718.4, notice of authorization day is September 10 in 2003, the name be called " a kind of vane type lockset " patent announcement a kind of lockset, this lockset is store the chamber with blade and is made as radially perforation, in each blade storage chamber two blades are set movingly and constitute the bidirectional blade structure, thereby greatly reduce mutual opening rate, improve theftproof performance, but disclosed lockset in this patent document, because the key of its each blade is to adopt ingot-shaped, its difficulty of processing of the key of this blade and employing is bigger, therefore makes that the lockset cost is higher.
The utility model content
The purpose of this utility model is the deficiency that solves above-mentioned vane type tapered end, and a kind of simple in structure, with low cost, mutual opening rate is low, theftproof performance is good vane type tapered end and the key suitable with it are provided.
The purpose of this utility model is achieved by the following technical solution: a kind of vane type tapered end, comprise lock cylinder, lock core shell, blade and leaf spring thereof, lock core is axially arranged with keyhole, lock core radially is provided with several blade that radially communicates storage chambeies and leaf spring storage chamber thereof, in each blade storage chamber, be provided with the blade of two move toward one another, each blade is provided with the slotted eye corresponding with key, it is characterized in that: described slotted eye is the deltiod slotted eye.
Further, the number in described blade storage chamber is five or four.
Further, asymmetric mutually with the both sides teeth of the suitable key of above-mentioned locking plate.
The beneficial effects of the utility model are: constitute the bidirectional blade structure owing to be provided with the blade of two move toward one another in each blade storage chamber, therefore greatly reduce mutual opening rate, and, slotted eye on the blade is the deltiod slotted eye, thereby make blade and key be easy to processing, so its cost is relatively low honest and clean.
Description of drawings
Fig. 1 is the structural representation that the vane type tapered end of the utility model embodiment matches with key
Fig. 2 is the A-A sectional view of Fig. 1
The specific embodiment
Now in conjunction with the accompanying drawings embodiment of the present utility model is further described:
As shown in the figure, the utility model embodiment, comprise lock cylinder 2, lock core shell 1, blade 4 and leaf spring 5 thereof, lock core 2 is axially arranged with keyhole 21, lock core 2 radially is provided with five blade storage chambeies 21 that radially communicate and leaf spring storage chamber thereof, in each blade storage chamber 21, be provided with the blade 4 of two move toward one another, each blade 4 is provided with the slotted eye corresponding with key 41, described slotted eye 41 is the deltiod slotted eye, the complementary symmetry of the both sides teeth of key 3, when key 3 inserts in the keyhole 21 (passing the slotted eye 41 on each blade 4), each blade 4 under the elastic force of spring 5 and with the corresponding snug fit of each teeth of key 3, at this moment, each blade 4 its outer face is just concordant with the endoporus of lock core 2, unblanks so can drive stop with key 3 rotations in lock core shell 1 with lock core 2.Adopt the blade (as shown in the figure) of five groups bi-directional configuration, its blade is if adopt three differential forms (promptly adopting three kinds of blades), the number of its coding is 3^10=59049, and if adopt one-way fashion, then its coding number is 3^5=243, so its gap is very huge, therefore adopt its mutual opening rate of two-way blade construction to reduce greatly, greatly improved the theftproof performance of lockset.
In the foregoing description, its blade storage chamber number can be other number as 4 or 5 etc. certainly.
Claims (4)
1, a kind of vane type tapered end, comprise lock cylinder, lock core shell, blade and leaf spring thereof, lock core is axially arranged with keyhole, lock core radially is provided with several radially identical blade storage chambeies and leaf spring storage chamber thereof, in each blade storage chamber, be provided with the blade of two move toward one another, each blade is provided with the slotted eye corresponding with key, it is characterized in that: described slotted eye is the deltiod slotted eye.
2, vane type tapered end as claimed in claim 1 is characterized in that: the number in described blade storage chamber is five or four.
3, the suitable key of the described vane type tapered end of a kind of and claim 1, it is characterized in that: each teeth of this key are corresponding one by one with the deltiod slotted eye of each blade under the spring force effect, snug fit.
4, key as claimed in claim 3 is characterized in that: the both sides teeth of this key are asymmetric mutually.
