Description
Technical field
The utility model belongs to lockset processing technique field, is specifically related to a kind of Anti-theft vane lock.
Background technology
Blade lock is divided into spring blade lock and Springless blade lock two class, and Reed lock is exactly the another name of spring blade lock.At present, Springless blade lock, security performance little with its lock core size is better than the advantages such as common cylinder lock market circulation is more at home; And Reed lock is because complex structure, security performance are good, high in cost of production feature, domestic usual is done antitheft use in the important events such as national treasury, strongbox.Reed lock is compared with Springless blade lock with common cylinder lock, has the advantage that size of key is large, lock intracorporeal space is large, can arrange that the frame for movement of more complicated controls to lock interior moving component, thus reach good anti-technology unlocking object.Thus, how to overcome manufacture difficulty and the cost of Reed lock, it is the technical barrier of current lockset manufacture field that its universalness is used.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and cost of manufacture is low, the Anti-theft vane lock that security performance is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Anti-theft vane lock, comprise the base plate of hollow, lock shaft and dead bolt, base plate is built-in with chamber plate, the central authorities of chamber plate have rectangular opening, the root of lock shaft is fixed on base plate, the extension of lock shaft is through this rectangular opening, and be arranged with cam I and cam II from the inside to the outside successively, clamping plate are provided with between cam I and cam II, in rectangular opening, U-shaped blade is provided with between clamping plate and cam II, blade is connected with chamber plate by spring, the position that chamber plate is positioned at above blade is embedded with damping bolt by spring, the position that chamber plate is positioned at below blade is embedded with tongue bolt processed by spring, one end of dead bolt is through bottom panel side, its other end is connected with base plate by spring, dead bolt has the tongue mouth mated with cam II.
Further, the edge of above-mentioned cam I is provided with centrosymmetric two flanges.
Further, the edge of above-mentioned cam II is provided with projection, and the edge of cam II and the centrosymmetric position of projection have groove.
Compared with prior art, the utility model has the advantages that: blade lock structure of the present utility model is simply novel, and cost of manufacture is cheap, by two cam engagement work, theftproof performance is good, safe and reliable, is adapted at average family and promotes the use of.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is first half structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model.
Wherein, 1, base plate, 2, chamber plate, 3, blade, 4, cam I, 41, cam II, 5, damping bolt, 6, tongue bolt processed, 7, clamping plate, 8, lock shaft, 9, dead bolt, 91, tongue mouth.
Detailed description of the invention:
As shown in Figure 1 to Figure 2, Anti-theft vane lock, comprise the base plate 1 of hollow, lock shaft 8 and dead bolt 9, base plate 1 is built-in with chamber plate 2, the central authorities of chamber plate 2 have rectangular opening, the root of lock shaft 8 is fixed on base plate 1, the extension of lock shaft 8 is through this rectangular opening, and be arranged with cam I4 and cam II41 from the inside to the outside successively, the edge of cam I4 is provided with centrosymmetric two flanges, the edge of cam II41 is provided with projection, the edge of cam II and the centrosymmetric position of projection have groove, clamping plate 7 are provided with between cam I4 and cam II41, in rectangular opening, U-shaped blade 3 is provided with between clamping plate 7 and cam II41, blade 3 is connected with chamber plate 2 by spring, the position that chamber plate 2 is positioned at above blade 3 is embedded with damping bolt 5 by spring, the position that chamber plate 2 is positioned at below blade 3 is embedded with tongue bolt 6 processed by spring, one end of dead bolt 9 is through base plate 1 side, its other end is connected with base plate 1 by spring, dead bolt 9 has the tongue mouth 91 mated with cam II41.
The operating principle of blade lock of the present utility model is as follows: time initial, the flange of cam I4 does not contact with damping bolt 5, damping bolt 5 moves down under the action of the spring, damping is applied to blade 3, blade 3 is stoped to move, only have after inserting key or unlocking tool in lock shaft 8, cam I4 could rotate under the effect of key or unlocking tool, controls blade 3 and moves left and right; Cam II41 under the effect of key with cam I4 rotating Vortex, when rotating to certain angle, notch alignment on notch on groove on cam II, blade 3 and tongue bolt 6 processed, tongue bolt 6 processed under the action of the spring on move, under the control of the projection of dead bolt 9 on cam II41 in retraction lock body, reach the object of unblanking; In the process, because the position unlocking tool of dead bolt 9 in lock body is not easy to encounter, thus can not determine by the method soundd out that definite relation between the groove of cam II41 and tongue bolt 6 notch processed is to unblank.In the scope that interaction between cam I4 and cam II41 makes key rotate 90 degree in lock shaft 8 all in the control of associated components, unblank by the technology that special unlocking tool is difficult to by stirring blade 3, the more current blade lock of security performance is greatly improved.
