Description

Blade locking head

Technical field

The utility model relates to a kind of mechanical lock head, particularly relates to a kind of mechanical type blade locking head.

Background technology

Existing mechanical type blade locking head comprises lock tube, lock core, key, blade, leaf spring, locking bolt and locking bolt spring, the blade be wherein arranged in the blade groove of lock core is quadrilateral structure, leaf spring is arranged between blade side and lock tube, and blade wherein outside is provided with V-notch, when after insertion key, each blade top makes V-notch on each blade outboard just to the V-arrangement head inside locking bolt to lockset position of coupler by apical tooth on the key, locking bolt moves under locking bolt spring action in lock core, be separated with the axial groove on lock tube outside locking bolt, lock core is made to rotate relative to lock tube thus to realize unblanking, extract out in the process of key, blade utilizes the V-notch on outside it by force locking bolt to be reset to the axial groove being positioned at lock tube outside it, thus the chien shih lock core making locking bolt be positioned at the set bar groove of lock core and the axial groove of lock tube can not rotate relative to lock tube and realize locking, the shortcoming of this blade lock is blade is quadrilateral structure, takes up room excessive, and the moving range of blade is too little, and under the condition of identical differential identical blade quantity, its secret key amount is too low, thus causes its theftproof performance too low.

Summary of the invention

The purpose of this utility model is to solve the problem that secret key amount is low, theftproof performance is poor existed in existing blade lock, and provides the blade locking head that a kind of secret key amount is large, theftproof performance is high.

The purpose of this utility model is achieved in that a kind of blade locking head, comprise lock tube, lock core, key, blade, leaf spring, locking bolt and locking bolt spring, described blade is made up of two vertical guiding pin and the transverse link that is connected to described two guiding pin upper ends, insert the key after the keyhole of lock core between two guiding pin of described blade, a wherein guiding outside of foot of described blade is provided with the breach matched with described locking bolt the inner, and is provided with the weighted table matched with described tooth on the key inside a wherein guiding pin of described blade; Described leaf spring is arranged between described blade and lock core.Blade is positioned at the blade groove of lock core.

Described leaf spring lower end is pushed down on the upside of the transverse link of described blade, and leaf spring lid is withstood in described leaf spring upper end, and this leaf spring lid is positioned at the oral area of the blade groove of described lock core.

Owing to have employed technical scheme described in the utility model, namely the portal structures that blade is only has three limits, because lack below compared with the blade used with existing blade lock, so the distance increase slided up and down at the identical differential condition lower blade of same volume, the blade quantity of different size increases, be equivalent to secret key amount increase, so the mutual opening rate of lockset reduces, improve the theftproof performance of lockset.

Detailed description of the invention

Composition graphs 1 and Fig. 2, described blade locking head, comprises lock tube 1, lock core 2, key 9 (Fig. 2), six blades, 5, six leaf springs 61, locking bolt 3 and two locking bolt springs 42;

Holding on the downside of key with left hand in the keyhole first key in Fig. 3 being inserted lock core 2 in Fig. 1 during installation makes key be unlikely to come off from lock core 2, then six blades 5 are put into respectively six blade grooves 22 (see Fig. 6) of lock core 22, again along six leaf springs 61 putting into Fig. 1 in Fig. 6 Leaf spring eye 23, leaf spring lid 62 in Fig. 1 is covered on the upside of lock core 2, again the locking bolt 3 in Fig. 1 is put into the set bar groove 21 of Fig. 6 lock core, then the lock core hole 10 of Fig. 1 lock tube is put into simultaneously with lock core 2, in the draw-in groove that lock tube 1 afterbody jump ring snaps in the lock core tail end stretching out lock tube afterbody outer end, lock core is axially fixed in lock tube, then the ball of two in Fig. 1 41 and locking bolt spring 42 are respectively charged in the spring eye of two shown in Fig. 4 and again the locking bolt spring cup 43 in Figure 43 are covered outside the lock tube in Fig. 4.

See Fig. 8 and Fig. 9, now locking bolt 3 outer end (Figure 8 shows that right-hand member) is positioned at the axial groove 11 of lock tube during blocking as shown in Figure 8, and locking bolt the inner is positioned at the set bar groove 21 of lock core, so lock core can not rotate relative to lock tube; When unblanking, key is inserted in keyhole, blade 5 is moved upwards up to state shown in Fig. 9 by weighted table 50 under tooth on the key promotes, now, breach outside the guiding pin 51 of blade 5 is just inner to locking bolt 3, locking bolt is pushed to blade 5 by ball under the effect of locking bolt spring force, make locking bolt 3 outer end be separated with the axial groove of lock tube as shown in Figure 9, after rotating key, lock core namely can be made to rotate relative to lock tube, thus realize unblanking object.Extract out during locking in the process of key, respectively the blade of process is pushed away up or down under the tooth in diverse location on the key and the effect of leaf spring, utilize Leaf Conductance outwards to be resetted and locking by locking bolt by force to the V-shaped groove on outside of foot.
