Abstract

The utility model relates to a multi-hole tumbler pin lock core which is applied to the light industry for making locks. The utility model is composed of a lock core and a key, wherein a core body is fixed in an outer casing by the lock core; a long tumbler pin, a short tumbler pin, and a thin spring are respectively arranged in the holes of the outer casing and the core body and are fixed by screws; a lock tongue is fixed on the core body by rivets; a thick spring is arranged on a key core of the key and is arranged in a casing, and an integrative structure which is formed in the way that a key head is fixed on a key disk is fixed with the key core into a whole. The utility model has the advantages of scientific design, novel conception, reasonable technology, suitable cost, difficult imitation, good anti-theft performance, and convenient unlocking and locking.

Description

The porous lock cylinder

The utility model relates to a kind of lock core device in the light industry lockmaking industry.

At present, light industry lockmaking industry history is remote both at home and abroad, but do not leave traditional principle and structure for many years always, thereby on anti-theft security, also need explore, the locking product that use are of a great variety now, comprise door lock, lock, sash lock, cabinet lock or the like, these principle is to make the lock opening and closing by radially moving back and forth substantially, it is cumbersome to make technology like this, complex structure, theftproof performance is relatively poor, especially key is made easily and is copied by other people, and difference is less because making is got up, and therefore develop a kind of novel porous lock cylinder is current urgency new problem to be solved always.

The purpose of this utility model is exactly that a kind of novel, design principle science, technology are easy to realize in order to provide, Costco Wholesale is suitable, properties of product are reliable, theftproof performance is superior, take axially reciprocating, open and close is convenient, imitated extremely difficult porous lock cylinder.

The purpose of this utility model is achieved in that whole device is made up of lock core and key two parts, lock core comprises dead bolt, rivet, screw, hairspring, short pellet shot from a slingshot, overcoat, core body, long marble, core body is fixed in the overcoat, and long marble, short pellet shot from a slingshot, hairspring be respectively charged in the hole of overcoat and core body, be screwed, dead bolt be fixed on the core body with rivet; Key comprises key core, housing, bulky spring, key dish, key head, the bulky spring of on the key core, packing into, and in the housing of again it being packed into, and the integral body and the key core that are used on the key dish behind the fixing key head are fixed as one.Main points of the present utility model are its design principle and structural shape.Its operating principle and using method are: this product is realized the opening and closing of lock with the axially-movable of pellet shot from a slingshot, key imitated very difficult, theftproof performance is reliable, when it uses the key head of key is inserted in the hole of lock core and rotates, make core body, dead bolt rotation, realize the opening and closing circulation.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the utility model lock core structure schematic diagram.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is a Key structure schematic diagram of the present utility model.

Fig. 4 is the vertical view of Fig. 3.

With reference to accompanying drawing, whole device is made up of lock core and key two parts, lock core comprises dead bolt 1, rivet 2, screw 3, hairspring 4, short pellet shot from a slingshot 5, overcoat 6, core body 7, long marble 8, core body 7 is fixed in the overcoat 6, and long marble 8, short pellet shot from a slingshot 5, hairspring 4 be respectively charged in the hole of overcoat 6 and core body 7, fixing with screw 3, with rivet 2 dead bolt 1 is fixed on the core body 7; Key comprises key core 9, housing 10, bulky spring 11, key dish 12, key head 13, the bulky spring 11 of packing on key core 9, in the housing 10 of again it being packed into, and be used on the key dish 12 fixedly that the integral body of key head 13 and key core 9 are fixed as one.

Multi-hole tumbler-pin lock core compared with prior art has novel, design science, cost is suitable, anti-The advantages such as the property stolen is good, axially-movable, convenient, the imitated difficulty of switch will be widely used in light industry lockmaking row In the industry.
