CN2278736Y - Multirow bit key and lock cylinder assembly - Google Patents

Abstract

The utility model relates to a key and a lock core assembly with a plurality of rows of bits, comprising a key and a cylindrical lock core, wherein, the key is provided with two rows of a plurality of rows of bit teeth which are staggered; the lock core is provided with two row or a plurality of lock beans corresponding to the key bit teeth. The utility model can effectively increase opening safety coefficient of the key and the lock core of a mechanical lock, reducing the possibility of illegal unlocking, and thus the performance of the theft protection and the safety of the mechanical lock is suitable for wide application area.

Description

Many row's clavis spoon lock core assemblies

The utility model relates to the mechanical lock part, especially a kind of key cylinder assembly with many row's teeth.

The unlatching control section of mechanical lock is made up of key and lock core in the prior art.This key and lock core have a toothrow tooth and row's lock beans of mutual correspondence.Yet there is the lower defective of insurance anti-theft feature in single row configuration, is illegally opened by the robber easily, causes any property loss to the user.

The purpose of this utility model is intended to propose a kind of by increasing many rows clavis spoon lock core assembly that teeth row number improves the security performance of mechanical lock, to overcome the deficiencies in the prior art part.

The purpose of this utility model can be achieved through the following technical solutions.

Many row's clavis spoon lock core assemblies comprise key and lock cylinder.In the utility model, key has the teeth of two row or multi-row phase side set.Lock core has two row or multi-row and the corresponding lock beans of key teeth.

Below in conjunction with embodiment of the present utility model and accompanying drawing, many rows clavis spoon lock core assembly is described in detail.

Fig. 5 key with two rows of teeth upward view;

Fig. 6 double rows of teeth lock core schematic diagram.

Many row's clavis spoon lock core assemblies can be: key has two row or three toothrow teeth, and its lock core then has two rows or the corresponding lock of three rows beans.

The key body 1 of many row's clavis spoon lock core assemblies can be cylindrical, the uniform twist cylindrical key surface that is arranged in of its many toothrows tooth 2; Lock core 3 endoporus that cooperate with key are also for cylindrical, and the also corresponding helical arrangement of lock beans 4 is on hole wall.

The key body 6 of many row's clavis spoon lock core assemblies also can be straight plate shape, and many toothrows tooth 5 is set up in parallel, and leaves gap 7 between each toothrow tooth; With also corresponding being set up in parallel of lock beans 10 on the lock core that key cooperates.Be shaped for ease of teeth, key is divided into single body 8,9 according to teeth row, divides other single body and function mechanical system or bonding way to connect into integral body at last.

It is still very convenient that the utility model and common single key cylinder are compared use. For the helical tooth structure, only The screw key of need taking advantage of a situation can insert lock core, continues rotation, just can normally unblank. The straight plate toothing of many rows Then identical with common monorow tooth structure, as broad as long when unblanking.

Many row's clavis spoon lock core modular constructions can improve the unlatching peace between mechanical lock key and the lock core effectively Overall coefficient greatly reduces the possibility of illegally unblanking, and makes antitheft, the safety performance of mechanical lock be suitable for wider General application.
