Abstract
The utility model relates to a lock, in particular to a lamina padlock. A highly pick-proof lamina padlock comprises a lock shell, a lock core and a lamina reset spring; the lamina slots of the lock core are connected as a whole to form an axial communication slot; a lamina with inner teeth is arranged between laminas, which can make two-way free sliding. The beneficial effects are that the lamina slot is a communication slot, and the spring-less lamina with inner teeth is movably arranged between laminas with spring top blocks, thus the lamina slot is full of laminas and lock cores with same sizes are provided with maximal laminas, so as to enable a lower mutually unlocking rate. Moreover, when the free and two-way sliding lamina is in use, the picklock can not find the exact location to open the lock, thus the utility model has good pick-proof performance. A location wedging mechanism is arranged between the lock slot and the blade of the utility model, hence a better pick-proof performance.
Description
Technical field
Relate to a kind of lockset in utility model, relate in particular to a kind of padlock head.
Background technology
At present, the blade lock is a kind of lockset commonly used, the tapered end of blade lock comprises lock housing, lock core, blade and blade back-moving spring, blade is arranged in the blade groove of lock core, corresponding with it blade back-moving spring is arranged in the spring eye of lock core, blade is provided with the spring jacking block, the blade back-moving spring snaps in the locked groove of lock housing blade by the spring jacking block, a slice blade or two blades can be set in locked groove of this blade locking head, and be divided into single blade locking head and twayblade tapered end, but all also have muscle or gap between its blade groove or the blade, and each blade has all the blade back-moving spring corresponding one by one with it, the mutual opening rate of this blade locking head is still waiting further reduction, in addition, stealer can be chosen blade with sensation one by one with instrument from locked groove, last technical unlocking blade lock, and theftproof performance also is not fine.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of mutual opening rate lower, the padlock head that theftproof performance is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of high antitheft blade locking head, comprise lock housing, lock core, blade and blade back-moving spring, the blade groove of described lock core fuses, be an axial connectivity slot, and between blade, be provided with the two-way blade that has internal tooth that is free to slide of energy.
The beneficial effects of the utility model are: because blade groove is a groove, and between the blade that has the spring jacking block, be provided with the blade of no spring of band internal tooth versatilely, make and be full of blade in the blade groove, make blade set in the lock core of same size maximum, thereby has a lower advantage of mutual opening rate, in addition, the blade of the free two-way slip of this energy, make stealer can't feel it the position that can open where, thereby also has a good advantage of theftproof performance, as further improvement, also be provided with screens mechanism between locked groove of this blade locking head and the blade, thereby its theftproof performance is better.
Description of drawings:
Fig. 1: be structural representation of the present utility model;
Fig. 2: be the A-A sectional view (one of screens mechanism structure) of Fig. 1;
Fig. 3: be another structural representation of screens mechanism (screens mechanism structure two);
Fig. 4: be the structural representation of key.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As shown in Figure 1, a kind of high antitheft blade locking head comprises lock housing 1, lock core 2, blade 3 and blade back-moving spring 4, and the blade groove of described lock core 2 fuses, be an axial connectivity slot 5, and between blade 3, be provided with the two-way blade that has internal tooth 6 that is free to slide of energy.Described connectivity slot 5 is radially also connecting, and is corresponding with it, offers two locked grooves 7 of symmetry in lock housing 1.The slip of described blade 5 drives by adjacent vanes 3 or deadweight is slided, its position has uncertainty, be blade 5 can arbitrary in two locked grooves 7 in, also might be not in locked groove 7, this point just, make the robber can not determine that its position opens or lock, increased difficulty of technical opening greatly.In the present embodiment, blade 3 has 5, and blade 5 has 6.As shown in Figure 4, be provided with lock tooth 15 in the side of key 14, be used to open several blades that have the spring jacking block 3, offer teeth groove 16 in the front of key 14, suitable with the internal tooth in the blade 5 of being with internal tooth.
Described locked groove 7 is provided with screens mechanism 8 with the lock-bit portion of blade 3.There are two kinds of structures in described screens mechanism 8, and as shown in Figure 2, described screens mechanism 8 is that two lock-bit limits 9 of locked groove 7 are provided with block 10, and the lock-bit limit of suitable with it blade 3 is provided with groove 11.As shown in Figure 3, described screens mechanism 8 is that two lock-bit limits 9 of locked groove 7 are provided with groove 12, and the lock-bit limit of suitable with it blade 3 is provided with block 13.When the robber stirred blade 3 with instrument, blade 3 can be amesiality, and screens mechanism 8 has an effect, and blade 3 can not be withdrawn, and lock core 2 just can not rotate.
