The specific embodiment
Defective at prior art exists describes in further detail of the present utility model for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
Shown in accompanying drawing 1～4, the lockhole of the delivery type theftproof lock that present embodiment discloses is hidden in the theftproof lock, can prevent to destroy lock core from the lockhole of lock core, improves the safety of theftproof lock.
The delivery type theftproof lock that the utility model discloses is equipped with the lock body 1 of lock core 11, is provided with at lock core 11 front end faces and interts the lockhole 12 of key, is equipped with on lock body 1 and blocks lockhole 12 and be used to carry the key connecting gear 2 that key moves and rotates.This key connecting gear 2 comprises the litter 21 that a vertical lock core 11 is provided with, on litter 21, offer the step through-hole 211 that vertical litter 21 length directions are provided with, in through hole 211, be interspersed with rotatable and along the flexible handle 22 of through hole, handle 22 outer ends extend outside the litter 21, handle 22 the inners are arranged in through hole 211 and are provided with the fixedly groove 221 of key in this end, and the flexible distance of handle 22 is greater than key length.Handle 22 the inners of present embodiment are provided with and prevent that handle 22 is from the logical bulge loop 222 that skids off in the air.
Are installed on the lock body 1 for litter 21 is stablized, litter 21 is installed on the lock body 1 by an outer cover 3, and outer cover 3 is provided with for handle 22 and stretches out short slot 31.
In the time of need unblanking, litter 21 is outwards slided, make through hole 211 skid off lock body 1, then key is inserted in the groove 221 of handle 22 the inners, again litter 21 is inwardly slided, the lockhole that makes through hole 211 and handle 22 those ends and lock core is to it, and driving handle 22 enters in the lockhole key then, and twisting handle 22 can be realized unlocking action.
Above-mentioned delivery type theftproof lock is suitable for the lock of forms such as existing U-shape lock is improved, and is adapted in the door lock in order to make the utility model, and the cross section of litter 21 can be circle, is positioned at the L shaped of short slot 31 litter 21 rotations for the benefit of on the outer cover 3.
Again in detail as shown in Figure 5, for more easy to use, lock body is provided with one and drives the key connecting gear group of motors 4 of operation automatically, and group of motors 4 is by rack-and-pinion and key connecting gear interlock.In this programme, group of motors 4 comprises and drives litter 21 translations respectively, drives that litter 21 rotates, driving handle 22 moves up and down, drives first motor 41, second motor 42, the 3rd motor 43 and the 4th motor 44 that lock core 11 rotates, each motor output shaft is provided with gear, and is provided with first tooth bar 45 that cogs and directly mesh with first motor 41 in litter 21 along its length.Be provided with first gear ring 46 that cogs and directly mesh with second motor 42 in litter 21 ends, this gear, first gear ring 46 are helical gear, helical teeth circle.Handle 22 sidewalls be provided with along the direct geared on handle 22 length directions and the 3rd motor 43 engagement second tooth bar 47.Lock core 11 is provided with second gear ring 48 that cogs and directly mesh with the 4th motor 44.Each motor is all realized coordination by controller.
