Description
Technical field
The utility model relates to a kind of lock core, is specifically related to a kind of lock core with limited post, belongs to mechanical lock field.
Background technology
The rank of China's theftproof lock is divided into common protection level and senior protection level two kinds, represents respectively by A level and B level.B level theftproof lock is higher due to its price, and company or the individual generally only with certain economic strength could use, and its cost of A level theftproof lock is lower, and these people widely use.But although A level theftproof lock is cheap, theftproof performance is poor, for some poly-talented means of unblanking, A level theftproof lock cannot stop its criminal offence.
Utility model content
The utility model is poor for solving existing A level theftproof lock theftproof performance, and B level theftproof lock cost is higher, is not suitable for the problem promoted the use of, and then proposes a kind of lock core with limited post.
The utility model is the technical scheme taked that solves the problem: the utility model comprises internal cylinder and outer lock core, internal cylinder is inserted in the jack on outer lock core top, the utility model also comprises multiple column body, multiple lower prop, multiple spring, multiple sealing bead and multiple limited post, the lower hole wall of the keyhole of internal cylinder has multiple first through hole from left to right successively side by side, the lower hole wall of the jack of lock core has multiple second through hole from left to right successively side by side, multiple first through hole is communicated with multiple second through hole one_to_one corresponding, a column body is respectively equipped with in each first through hole, each second through hole is provided with a lower prop from top to bottom successively, a spring, a sealing bead, a limited post is respectively equipped with in each spring, distance between the upper surface of each limited post and the lower surface of corresponding lower prop is H, the hole depth of each first through hole is D, the height of each column body is L, (L-D) < H < L.
The beneficial effects of the utility model are: 1, lock core can the personnel that effectively avoid theft be pried open by the utility model, avoids the financial losses of people; 2, the utility model structure is simple, cost of manufacture is cheap, and only needing on original A level theftproof lock, carry out simple repacking can promote anti-theft grade; 3, cost of manufacture of the present utility model is far below the price of B level theftproof lock, and the people being suitable for vast wage-earners uses.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model, and Fig. 2 is A place enlarged drawing in Fig. 1.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 and Fig. 2 illustrate present embodiment, described in present embodiment, a kind of lock core with limited post comprises internal cylinder 1 and outer lock core 2, internal cylinder 1 is inserted in the jack 2-1 on outer lock core 2 top, present embodiment also comprises multiple column body 3, multiple lower prop 4, multiple spring 5, multiple sealing bead 6 and multiple limited post 7, the lower hole wall of the keyhole 1-1 of internal cylinder 1 has multiple first through hole 1-2 from left to right successively side by side, the lower hole wall of the jack 2-1 of lock core 2 has multiple second through hole 2-2 from left to right successively side by side, multiple first through hole 1-2 is communicated with multiple second through hole 2-2 one_to_one corresponding, a column body 3 is respectively equipped with in each first through hole 1-2, each second through hole 2-2 is provided with a lower prop 4 from top to bottom successively, a spring 5, a sealing bead 6, a limited post 7 is respectively equipped with in each spring 5, distance between the upper surface of each limited post 7 and the lower surface of corresponding lower prop 4 is H, the hole depth of each first through hole 1-2 is D, the height of each column body 3 is L, (L-D) < H < L.
