Abstract

The utility model relates to a vane lock head, which is designed for problem that key waves of a vane lock in existence are easily copied and comprises a lock head and a lock core. The lock core has a vane groove which is inserted with the vane. The vane has tooth grooves matching with the key and the lock head has clamping grooves matching with the vane which has a limit protruding platform. The lock core has a clamping resistance platform matching with the limit protruding platform. The utility model has advantages of reasonable and simple structure, effective prevention of measuring the key waves through the tooth grooves on the vane, good safety performance, high private key quantity and smooth movement of the vane.

Description

A kind of blade locking head

Technical field: the utility model belongs to a kind of blade locking head.

Background technology: existing blade locking head, two kinds of structures are arranged, a kind of tapered end that includes, lock core, blade groove is arranged on lock core, be inserted with blade in the blade groove, the alveolus that matches with key is arranged on the blade, the draw-in groove that cooperates with blade is arranged on tapered end, when extracting key out, blade tip enters the draw-in groove on the tapered end, lock core and tapered end can not relatively rotate, and when inserting key, the blade two ends are concordant with the face of cylinder of lock core, can relatively rotate between lock core and the tapered end, this kind tapered end has overcome the shortcoming of ball cylinder lock, but owing to adopted the insertion key rear blade two ends structure concordant with the face of cylinder of lock core, with dialling rod the alveolus on the blade is stirred to the draw-in groove direction of tapered end, when blade pushes up draw-in groove, just can measure the permanent position of blade alveolus, and, outwards move and dial rod because draw-in groove is a linear, the waveform of alveolus on the blade just can draw, be the wave mode of key, be easy to carry out duplicating of key that security performance is relatively poor.Structure and preceding a kind of structure of another kind of blade locking head are basic identical, and just blade groove is a groove, is placed with contacted blade in the groove, and this lockset has blade easily to install, and blade quantity is many, and size of key is than advantages such as height.But still can't prevent to draw the waveform of alveolus on the blade with dialling rod, security performance is relatively poor.

Summary of the invention: one of the purpose of this utility model is to address the above problem, and provides a kind of can preventing effectively to draw the wave mode of key, blade locking head simple in structure, that security performance is good by dialling rod.Two of the purpose of this utility model is both to keep size of key, can prevent from effectively again to draw the wave mode of key by dialling rod.Three of the purpose of this utility model is further to increase improper difficulty of stirring blade, makes blade movement level and smooth.

The utility model includes tapered end, lock core, and blade groove is arranged on lock core, is inserted with blade in the blade groove, the alveolus that matches with key is arranged on the blade, the draw-in groove that cooperates with blade is arranged on tapered end, positive stop lug boss is arranged on the blade, the screens that stops that matches with positive stop lug boss is arranged on lock core.

The utility model blade groove is an at least one group of groove, is placed with contacted blade in the groove.

The utility model positive stop lug boss is two positive stop lug boss, and the jump ring groove is arranged on lock core, is inserted with the bar shaped jump ring in the jump ring groove, and the bar shaped jump ring is stuck between two positive stop lug boss.

The utility model is rational in infrastructure, simple, can prevent to measure by the alveolus on the blade waveform situation of key effectively, and security performance is good, size of key is high, blade movement is level and smooth.

The specific embodiment:

Embodiment one.As shown in Figure 1, 2, 3, the utility model includes tapered end 1, lock core 4, on lock core 4, blade groove is arranged, be inserted with blade 3 in the blade groove, blade groove is a groove 9, is placed with contacted blade 3 in the groove 9, the alveolus 8 that matches with key is arranged on the blade 3, the draw-in groove 2 that cooperates with blade is arranged on tapered end 1, positive stop lug boss 6 is arranged on the blade, on lock core 4, have match with positive stop lug boss 6 stop screens 7.

When inserting key 5, the alveolus 8 on the blade cooperates with key 5, and blade 3 two ends are concordant with the face of cylinder of lock core 4, and lock core 4 can relatively rotate with tapered end 1; When extracting key 5 out, blade 3 ends enter the draw-in groove 2 on the tapered end at random, and lock core 4 can not relatively rotate with tapered end 1.Owing to be provided with positive stop lug boss 6, when insertion group rod was stirred the draw-in groove 2 of blade on tapered end, positive stop lug boss 6 was stuck in and stops in the screens 7, forms straight line, can't measure the waveform of key, and security performance is good.

As shown in Figure 2, the utility model alveolus is a boss 8, cooperates with the key 5 of interior waveform.

As shown in Figure 3, can be provided with active blade, prevent that dust from entering at end face 10 places of lock core 4.

Embodiment two.As shown in Figure 4, positive stop lug boss is two positive stop lug boss 11,14, and jump ring groove 12 is arranged on lock core 4, is inserted with bar shaped jump ring 13 in jump ring groove 12, and bar shaped jump ring 13 is stuck between two positive stop lug boss 11,14, increases by dialling rod to stir the difficulty that blade is unblanked.Other structure of present embodiment can be identical with embodiment one.

Embodiment three.As shown in Figure 5, the groove on the utility model lock core 4 has three groups, is placed with contacted blade 3 in every group of groove, and when inserting key, blade movement is more level and smooth.Certainly also can adopt the structure of two groups or more groups of grooves.Other structure of present embodiment can be identical with embodiment one.

Embodiment four.As shown in Figure 6, on lock core 4 blade groove is arranged, be inserted with blade 3 in the blade groove, promptly blade groove is separate, and blade does not contact mutually, and other structure of present embodiment can be identical with embodiment one.

The utility model blade also can adopt as Fig. 7 or Fig. 8 or structure shown in Figure 9.

As shown in Figure 5, the alveolus on the utility model blade is an open slot 15, cooperates outer waveform key.

As shown in Figure 6, the alveolus on the utility model blade is back type groove 16, cooperates outer waveform key.

As shown in Figure 7, the alveolus on the utility model blade is back the boss 17 that is provided with in the type groove 18, waveform key in cooperating.
