Abstract
The utility model provides a mechanical type puzzle lock, which comprises a dial, a lock seat, a drive shaft, a driving piece, a lock piece, etc. The driving piece and the lock piece are sheathed on the drive shaft. The edges of the driving piece and the lock piece are respectively provided with a straight edge. The edge of the driving piece is provided with a turning edge. The lock piece is arranged at the inner side of the turning edge. The utility model has the characteristics of simple structure, convenient operation, low cost, etc. The utility model can be used on drawers, file cabinets or safes.
Description
The utility model relates to a kind of coded lock, particularly mechanical code lock.
Mechanical code lock has been widely used in places such as strongbox and safety cabinet at present.In order to guarantee its safety, the general structure more complicated of mechanical code lock, troublesome poeration during unlatching.For some confidentiality and security requirement is not very high place, and as places such as drawer, file cabinets, people just are reluctant to use the prior mechanical coded lock.
The purpose of this utility model is at above-mentioned situation, and a kind of simple in structure, easy to operate mechanical code lock is provided.
The purpose of this utility model realizes by following technical proposal: this mechanical code lock comprises dial, lock, power transmission shaft, rotating plate and locking plate, power transmission shaft and dial are connected, rotating plate and locking plate are socketed on the power transmission shaft, one straight flange is all arranged on the edge of rotating plate and locking plate, and the edge of rotating plate is provided with and turns edge, and locking plate is positioned at the inboard that turns edge.In this mechanical code lock, dial drives rotating plate by power transmission shaft and locking plate rotates together.When the straight flange on rotating plate and the locking plate is in the position of setting simultaneously, could open coded lock.The antitheft effect that turned edge at rotating plate edge.Because turning edge of rotating plate encases locking plate, so can make the burglar can't judge when rotating plate does not go to the position of setting whether locking plate forwards the position of setting to, prevented that the burglar from making technical unlocking.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the generalized section of this mechanical code lock.
Fig. 2 is the schematic diagram of rotating plate in this mechanical code lock.
Fig. 3 is the sectional view of Fig. 2 along A-A.
Fig. 4 is the schematic diagram of locking plate in this mechanical code lock.
Among the figure, 1, dial; 2, power transmission shaft; 3, rotating plate; 30, turn edge; 4, lock; 5, locking plate; 6, screw.
As shown in Figure 1, this mechanical code lock comprises parts such as dial 1, lock 4, power transmission shaft 2, rotating plate 3 and locking plate 5.In the present embodiment, two locking plates 5 of socket on the power transmission shaft 2.On each locking plate 5 and the rotating plate 3 screw 6 is arranged all.When rotating plate 3 rotates, just can drive each locking plate 5 by screw 6 and rotate.As Fig. 2, Fig. 3 and shown in Figure 4, rotating plate 3 and locking plate 5 are disc, and the straight flange of an equal length is all arranged on its edge, and turn edge 30 on the rotating plate 3.When opening this coded lock, at first rotary dial 1, drives rotating plate 3 by power transmission shaft 2 and rotates together; Rotating plate 3 rotates locking plate 5 by screw 6 then, and the straight flange on each locking plate 5 goes to the position of setting successively; At last, rotating plate 3 just goes to the position of setting, and coded lock is opened.This mechanical code lock is particularly suitable on the drawer of desk or safety cabinet.When this coded lock was installed on the drawer, the state of unlatching generally selected its locking plate 5 all to be in and equal position, drawer face upper edge with straight flange on the rotating plate 3.After the locking plate 5 of coded lock and rotating plate 3 were upset, they will be blocked by the upper beam of drawer housing, can not open or closing drawers.
Compared with prior art, this mechanical code lock has simple in structure, easy to operate, product The characteristics such as cost is low also have certain theftproof performance simultaneously, can be widely used in drawer, file cabinet Perhaps on the safety box.
