The purpose of this utility model is to provide a kind of antitheft and anti-damage performance strong, and easy to use, make simple lock-protector.
The utility model adopts following technical scheme to achieve these goals: a kind of lock-protector, comprise protecgulum and bonnet, correspondence is provided with keyhole on protecgulum and the bonnet, it is characterized in that: be provided with rotating active gear ring between protecgulum and the bonnet, initiatively the gear ring inner ring is provided with and the meshing rotating driven tooth of active gear ring, driven gear ring is provided with a heteromorphic teeth, this heteromorphic teeth is complementary with the depression that the active gear ring is provided with, one place, driven gear ring edge is provided with a depression, initiatively be provided with a crescent shape body correcting plate between gear ring and the driven gear ring, driven gear ring is arranged on the recess of crescent shape body correcting plate, the inner ring of one end of crescent shape body correcting plate is provided with a protruding button, this protruding buckle is in the depression of driven gear ring, driven gear ring is provided with an eccentric keyhole, the correcting plate of crescent shape body is between protecgulum and bonnet, and becomes secure bond with protecgulum with bonnet.
Good effect of the present utility model is: adopt bidentate wheel single-point, and the engaging type principle, the inscribe gear drive reaches the password purpose with special shape gear.Volume is little, and anti-destruction anti-theft capability is strong, and simple to operate, easy to use, as long as correctly rotate gear ring by password that is provided with or mark, just can lock-protector be opened.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a preferred embodiment building block of a utility model decomposing schematic representation;
Fig. 2 is a preferable enforcement combination of a utility model back structural representation;
Fig. 3 is preferred embodiment lock keyhole of the utility model driven gear present position schematic diagram when opening;
Fig. 4 is preferred embodiment lock keyhole of the utility model driven gear ring present position schematic diagram when closing.
See also Fig. 1 to shown in Figure 4, the utility model is made up of protecgulum 10, bonnet 20, active gear ring 30, driven gear ring 40 and correcting plate 50.Correspondence is provided with keyhole 11,21 on protecgulum 10 and the bonnet 20.Be provided with rotating active gear ring 30 between protecgulum 10 and the bonnet 20, initiatively gear ring 30 inner rings are provided with and the meshing rotating driven gear ring 40 of active gear ring, driven gear ring 40 is provided with a heteromorphic teeth 41, and this heteromorphic teeth 41 is provided with depression 31 with active gear ring 30 and is complementary.One place, driven gear ring 40 edges is provided with depression 42.Initiatively be provided with the correcting plate 50 of a crescent shape body between gear ring 30 and the driven gear ring 40, driven gear ring 40 is arranged on the recess 51 of crescent shape body correcting plate 50.The inner ring of one end of crescent shape body correcting plate 50 is provided with a protruding button 52, and this protruding button 52 is in the depression 42 of driven gear ring 40.Driven gear ring 40 is provided with an eccentric keyhole 43.The correcting plate 50 of crescent shape body is in 20 of protecgulum 10 and bonnets, and with 20 one-tenth secure bond of protecgulum 10 and bonnet, initiatively gear ring 30 can drive driven gear ring 40 rotations, when lock keyhole is opened, at this moment, three lock keyholes 11,21 on protecgulum 10, bonnet 20 and the driven gear ring 40,43 one-tenth are ganged up.
The utility model is in manufacturing process, and the recess 51 of correcting plate 50 makes the easy on and off activity in correcting plate 50 recesses 51 of driven gear ring 40 down when guaranteeing to install, thereby makes driven gear ring 40 rely on its deadweight and initiatively gear ring 30 clutches.Protecgulum 10, bonnet 20 and correcting plate 50 threes maintain static.During use, rotate initiatively gear ring 30 to a direction of former setting earlier, be threaded to the password number or the assigned address of setting, make the heteromorphic teeth 41 of driven gear ring 40 fall into the initiatively depression 31 of gear ring 30, rotate initiatively gear ring 30 more round about, at this moment driven gear ring 40 can be followed initiatively gear ring 30 rotations, and the lock-protector keyhole is opened.
