With reference to Fig. 2.Described first pinball structure 4 comprises hoodle 43 on the first lower pellet 41, first spring 42 and first.Described first lower pellet 41 is fixed on the bottom of first passage 221, and described first spring 42 is connected on the first lower pellet 41 and first between hoodle 43, and on described first, fit in the end face of hoodle 43 and the bottom surface of column 5.

With reference to Fig. 3, Fig. 5, Fig. 6 and Fig. 8.The described horizontal direction turning core 23 is provided with front vane 6 and the rear blade 7 of all right one way or the other left and right activity, and this front vane 6 and rear blade 7 are respectively equipped with the groove 61 and groove 71 that can pass for key 3.The dual-side of described key 3 is equipped with the second groove 32, and wherein the second groove 32 of a side is fitted with the left internal side of the groove 61 of front vane 6, and the second groove 32 of another side is fitted with the right inside side of the groove 71 of rear blade 7.The horizontal direction of described bearing 22 is provided with third channel 222 and the four-way 223 of dislocation layout, the second pinball structure 8 is provided with in described third channel 222, the length of this second pinball structure 8 when normal use is equal with the length of third channel 222, and fits in the left side of its right side and front vane 6.Be provided with the 3rd pinball structure 9 in described four-way 223, the length of the 3rd pinball structure 9 when normal use is equal with the length of four-way 223, and fits in the right side of its left side and rear blade 7.The described core 23 that turns is provided with the Five-channel 233 that is communicated with third channel 222 and is communicated with the Hexamermis spp 234 of 223 with four-way.

With reference to Fig. 3.Described second pinball structure 8 comprises the second left hoodle 81, second spring 82 and the second right hoodle 83.Described second left hoodle 81 is fixed on the left part of third channel 222, and described second spring 82 is connected between the second left hoodle 81 and the second right hoodle 83, fits in the described right side of the second right hoodle 83 and the left side of front vane 6.Described 3rd pinball structure 9 comprises the 3rd left hoodle 91, the 3rd spring 92 and the 3rd right hoodle 93,3rd right hoodle 93 is fixedly connected on the right part of four-way 223, described 3rd spring 92 is connected between the 3rd left hoodle 91 and the 3rd right hoodle 93, fits in the described left side of the 3rd left hoodle 91 and the right side of rear blade 7.

With reference to Fig. 2 and Fig. 4.When described key 3 inserts, the first groove 31 bottom it is suitable with the top of column 5, and now the first pinball structure 4 is positioned at first passage 221, and column 5 is positioned at second channel 232, turns core 23 and just can rotate.When not inserting key 3, under the effect of the first spring 42 elastic force, on first, hoodle 43 can enter in second channel 232, and now turning core 23 cannot rotate.If insert other key, the first groove 31 is not established in the bottom due to other keys, therefore, when other keys insert, column 5 can be pressed down, and the bottom of column 5 can enter in first passage 221, now turn core 23 also cannot rotate, lock also just can not be opened by other keys.

With reference to Fig. 3, Fig. 6, Fig. 7, Fig. 8 and Fig. 9.In addition, when key 3 inserts, second groove 32 of this key 3 one side is fitted with the left internal side of the groove 61 of front vane 6, second groove 32 of another side is fitted with the right inside side of the groove 71 of rear blade 7, now the second right hoodle 83 is separated with Five-channel 233,3rd left hoodle 91 is separated with Hexamermis spp 234, turns core 23 and just can rotate.When not inserting described key 3, the second right hoodle 83 can enter in Five-channel 233, and the 3rd left hoodle 91 can enter in Hexamermis spp 234, and now turning core 23 cannot rotate.If insert other key, dual-side due to other keys does not establish the second groove 32, and therefore other keys are when inserting, and the left part of front vane 6 can enter in third channel 222, the right part of rear blade 7 can enter in four-way 223, now turns core 23 and also cannot rotate.Lock-protector 2 of the present utility model adds the antitheft effect in three roads, substantially increases the safety of theftproof lock.

So the utility model is not when lock-protector 2 is opened, and lock core 1 is also to rotate, and this not only adds the difficulty of technology unlocking, and lock core 1 coordinates described key 3 to greatly reduce the rate of answering out of lock core 1.

Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
